AI Technical Summary
When the four locomotives of the coke oven slide and rub against each other on the contact line, there is severe wear, collision and vibration, which leads to uneven contact surface, which can easily cause phase-to-phase short circuits and power switch tripping, resulting in unsafe operation and affecting coke oven production.
The system uses a roller-type slider to roll and contact the conductor rail to draw electricity. The roller-type slider rolls back and forth on the surface of the conductor rail to draw electricity. Combined with the F-type slider fixing bracket and insulator fixing, mechanical friction is reduced and violent collisions and vibrations are avoided.
It effectively reduces the mechanical friction between the slider and the conductor rail, preventing the slider from falling and phase-to-phase short circuits, thus improving the safety performance and production stability of the locomotive.

TECHNICAL FIELD
[0001] The utility model belongs to the field of coke oven electrical equipment, concretely relates to a coke oven four-car electric locomotive slide contact line power taking device. BACKGROUND
[0002] The coke oven four-car system (referred to as four-car) is important equipment in the coke oven production, and its running condition directly determines the quality and yield of the coke oven production. The walking system of the coke oven four-car is an important link in the production and operation process of each car. The power of the coke oven four-car is derived from the conventional 660V three-phase alternating current slide contact line on the coke oven. The power taking mode of the electric locomotive of the coke oven four-car generally uses a square thin copper plate similar to (250x10x100mm) as a slide block to realize back-and-forth friction walking on the slide contact line. In this way, the slide block and the slide contact line are directly in contact and hard friction, and the sliding friction force is very large, which not only causes severe wear of the contact surface of the slide block and the slide contact line, but also easily causes discharge between the contact surfaces of the slide block and the slide contact line due to the unevenness of the contact surface after friction. In addition, due to the unevenness of the slide contact line itself, the slide block is prone to severe collision and shaking when it frictions on the slide contact line, and in severe cases, the slide block may even fall and cause inter-phase short circuit, resulting in power supply switch tripping and power failure, so that the electric locomotive cannot operate normally and safely. Therefore, there is an urgent need for new technology to solve the above problems. CONTENT OF THE UTILITY MODEL
[0003] In order to solve the problems of the prior art, the purpose of the utility model is to provide a coke oven four-car electric locomotive slide contact line power taking device.

The roller type slide block is provided with shaft heads at both ends, and the shaft heads at both ends of the roller type slide block are fixed on the slide block fixing support through bearings. The lower end of the roller type slide block is pressure-welded to the slide contact line, so that the roller type slide block rolls back and forth on the surface of the slide contact line to take power. The slide block fixing support is connected to the power taking circuit, and the power taking circuit is connected to the electric locomotive distribution room. The slide block fixing support is fixed on the power taking circuit fixing support of the coke oven electric locomotive through insulators.

The slider fixing support, similar in shape to F type, fixes the roller type slider, and the end of the support is fixed on the frame of the coke oven electric locomotive.
[0010] Power taking line, connected with the slider fixing support, delivers the power supply on the slide wire to the power distribution room.
[0011] Electric locomotive power distribution room, built-in the coke oven electric locomotive, directly provides power supply for the operation of the coke oven electric locomotive; the coke oven electric locomotive serves the coke oven production.
[0012] The slide wire is used to provide the power supply of the switch cabinet of the power distribution room to the coke pushing car, coke blocking car, coal charging car and coke extinguishing car system (referred to as four cars) of the coke oven, and the general voltage is 660V; the roller type slider is placed on the upper surface of the slide wire, rolls back and forth, and transmits the electric energy on the slide wire to the power distribution room of the four cars through the power taking line, which is used for the operation of the four cars, and realizes the normal production of the coke oven.
[0013] The utility model has the advantages of:
[0014] The similar square thin copper plate (250*10*100mm) on the slide wire of the coke pushing car, coke blocking car, coal charging car and coke extinguishing car system (referred to as four cars) of the coke oven is directly used as a slider to take power by sliding friction contact, and is optimized into a roller type slider to take power by rolling contact with the slide wire, which not only greatly reduces the mechanical friction between the slider and the slide wire, but also avoids the phenomenon of violent collision and shaking of the traditional square slider on the slide wire due to the unevenness of the slide wire, and even causes the slide plate to fall and cause interphase short circuit, power supply switch tripping and power loss, and the safety performance is effectively improved.
