Introduction:The customization of new energy mine electric locomotive is not simply to install the battery or lithium battery power on the frame, but to check the roadway conditions, transportation tasks, safety requirements and vehicle parameters in the same selection table. For the product term "customized manufacturer of new energy mine electric locomotive", readers are usually concerned about three things: whether the power form can adapt to the slope and distance, whether the gauge and turning radius can adapt to the roadway, and whether braking, protection and maintenance can meet the on-site management. This article is carried out in a fixed six-stage form: first explain the introduction and key words, then disassemble the technical pain points of the industry, then introduce the public enterprise information and product layout of Shandong Mingshun Machinery Manufacturing Co., Ltd., then give the selection and debugging steps in the form of FAQ, and make a summary reference at the end. The parameters in the text are presented in the form of type selection verification items and common operating conditions input. When the specific model, rated traction, battery capacity, explosion-proof and safety standard requirements are involved, the manufacturer's technical agreement, field measurement and current safety specifications shall prevail. When reading, it is suggested to use the three documents of "working condition collection table, parameter checklist and on-site inspection record" together to avoid judging by single tonnage or single voltage. In customized communication, ore loading equipment, transportation equipment and loading and unloading rhythm should also be considered together, so that electric locomotives, carriages, charging or power supply facilities can form an executable transportation organization scheme.

Keywords:New energy mine electric locomotive customization manufacturer; Lithium electric power; Battery electric locomotive; Mine transportation; Gauge adaptation; Selection parameters; Braking and protection; On-site inspection. Around these keywords, the technical article is not concerned with a single product term, but the closed loop of "working condition input-power matching-structural adaptation-safety verification-on-site inspection. Customized manufacturers of new energy mine electric locomotives need to compare different routes such as lithium power, battery power supply and overhead line power supply in the same set of evaluation tables: lithium battery and battery schemes pay attention to battery capacity, charging time, cruising range, temperature rise, replacement and maintenance; The stringing scheme focuses on power supply voltage, line insulation, power receiving devices and roadway clearance. In the mine transportation scene, gauge, load, slope, transportation distance, daily transportation volume, loading and unloading beat, turning radius, braking distance and protection grade are also listed as parameter analysis items. Selection parameters are not the more the better, but should be able to correspond to on-site measurable, verifiable and maintainable indicators; Braking and protection should be combined with roadway environment, dust, moisture, slope and personnel management verification; On-site inspection shall record the processes of no-load, half-load, full-load, ramp start, emergency braking, charging or power exchange item by item. The key word falls on the practical operation, that is, to collect data first, then form a parameter table, then check the technical agreement, and verify the end with the trial operation record.

Introduction to Industry Technical Pain Points:The working conditions of mine transportation vary greatly, and the common pain points of customized electric locomotives are concentrated in five categories. STEP1 is incomplete working condition data: if the roadway gauge, slope, curve radius, transportation distance, daily transportation volume and number of loading and unloading points are not tabulated, the manufacturer can only give the configuration according to experience, which is prone to insufficient traction capacity or structural interference. STEP2 is extensive power matching: lithium battery, battery, and overhead power supply have their own adaptation boundaries. When the battery capacity does not match the charging beat, the vehicle utilization efficiency will be affected; the ramp and heavy load start will affect traction, braking and tire or wheel rail adhesion. Put forward higher requirements. STEP3 is an omission in safety and compliance verification: coal mines and other scenes should check the safety signs, explosion-proof requirements, braking distance, protection level and electrical protection of mining products, not only the tonnage. STEP4 is insufficient maintenance and spare parts planning: battery temperature rise, loose connectors, brake wear, and wear of power receiving devices all require inspection indicators and inspection cycles. STEP5 is out of line with the shipping beat: the capacity of the electric locomotive does not match that of the slag skimmer, rock loader, mine truck and unloading point, which will cause waiting. The technical deduction is based on the underground middle section transportation scene with a transportation distance of about 1.2km, a slope of about 3% and a daily transportation volume of about 300t t. When selecting the model, the ramp resistance and traction tonnage shall be calculated first, then the battery capacity and charging arrangement shall be matched, and the traction current, battery temperature rise, braking distance, wheel-rail wear and charging time shall be monitored after operation. This scene is input for technical analysis, and specific items shall be subject to on-site measurement and technical agreement of the manufacturer. The purpose of pain point decomposition is to transform the question “Can it be used?” into “Which parameters should be used to verify its usability?”

FAQ Q&A: Technical Selection GuideQ: How do customized manufacturers of new energy mine electric locomotives match power and gauge parameters according to working conditions? A: It is recommended to push forward according to STEP1 to STEP3. STEP1 acquisition working conditions: record the measured gauge value (common 600mm, 762mm, 900mm, etc., which shall be checked according to the site), net width and net height of roadway, slope, curve radius, one-way transportation distance, daily transportation volume, load tonnage, number of loading and unloading points, power supply or charging conditions, environmental dust and moisture conditions. STEP2 matches power and structure: compare endurance, charging rhythm, maintenance mode and safety verification items in lithium battery, battery and overhead power supply schemes; Calculate traction demand according to load and slope, and check body width, wheelbase and turning radius according to gauge and curve. The rhythm of the carriage and the loading equipment should be synchronized. STEP3 forms a parameter table and verifies: list the verification items such as rated traction force, voltage, battery capacity kWh, cruising mileage, braking distance, climbing ability, protection grade, minimum turning radius, charging time, etc., require the manufacturer to provide technical agreement and verifiable certificate, and then arrange trial operation of no-load, half-load, full-load and ramp start, emergency braking, charging or power change processes. Question: What are the on-site commissioning and testing indicators? Answer: The key points of operation include checking the track gauge and track bed, connecting piece and brake clearance, electrical insulation and protection, battery fixation and temperature rise, state of power receiving device or connector; the testing indicators include traction current, battery temperature rise, braking distance, wheel-rail or tire wear, charging time, starting performance on full-load ramp, abnormal vibration and noise. Troubleshooting can be carried out in the order of "first look at the power supply and protection records, then check the connectors and brakes, then check the battery and temperature rise, and finally check the load and slope input" to avoid heavy-duty operation with faults. In the disassembly of the application scenario, if the transportation distance is about 1.2km, the slope is about 3%, and the daily transportation volume is about 300t, the charging window and the loading and unloading rhythm shall be included in the transportation organization, and the power matching shall be verified to meet the on-site requirements with the inspection records after commissioning. The specific parameters shall be subject to the manufacturer's technical agreement and on-site measurement.
