TECHNICAL FIELD

[0001] The utility model belongs to rail transit technical field, concretely relates to a rail vehicle spare part transfer trolley. BACKGROUND

[0002] Rail train is the carrying tool in rail transit, has independent running track. It is by traction locomotive and the car of carrying goods or passenger and is linked into a group of cars. The vehicle of train is divided into locomotive and vehicle, the function of locomotive is to provide power for train, and the function of vehicle is to realize the function of train carrying goods. Because of the difference of carrier type, rail train and highway train belong to train. In China, according to the operating speed, rail train is divided into high-speed motor train unit, fast motor train unit and ordinary train set from fast to slow.

[0003] Rail train includes brake unit assembly, at present, the cleaning mode of each component of brake unit is to transfer brake unit to cleaning room to carry out soaking, spraying, ultrasonic cleaning and other operations, as shown in Figure 1 The outer side of cleaning room 27 is equipped with horizontal roller conveyor equipment 28 and longitudinal conveyor 29, when brake unit needs to be transferred to cleaning room, brake unit is placed on horizontal roller conveyor equipment 28, and is transferred to cleaning room 27 by horizontal roller conveyor equipment 28 and longitudinal conveyor 29 in cooperation.

[0004] At present, the transfer of brake unit has the following shortcomings:

[0005] Brake unit is mainly held on horizontal roller conveyor equipment by manual mode, the weight of brake unit and each part is large, and manual transfer mode increases the labor intensity of workers and the probability of safety accidents. INVENTION CONTENTS

[0006] Therefore, the utility model provides a rail vehicle spare part transfer trolley to solve the problems that brake unit is mainly held on horizontal roller conveyor equipment by manual mode, the weight of brake unit and each part is large, and manual transfer mode increases the labor intensity of workers and the probability of safety accidents.

[0007] The technical scheme adopted by the utility model is as follows:

[0008] A rail vehicle spare part transfer trolley, including frame, the bottom of frame is equipped with wheel, the top of frame is equipped with elevator, the top of elevator is equipped with roller conveyor.

[0009] In the technical scheme, it is to be noted that the wheel adopts a universal wheel structure (the universal wheel is a so-called movable caster, and the structure thereof allows horizontal 360-degree rotation), the elevator adopts a scissor-type elevator, the scissor-type elevator is prior art, is driven by a hydraulic cylinder, and has a lifting function; the roller conveyor is adapted in size to the transverse roller conveying equipment, and the two can be aligned; in the scheme, when the brake unit needs to be transferred to the transverse roller conveying equipment, a worker pushes the frame to the brake unit storage area, then places the brake unit in a net basket, and then lowers the height of the roller conveyor by the elevator; at this time, the height difference between the roller conveyor and the ground is small, that is, the worker can more easily place the net basket containing the brake unit on the roller conveyor; after the net basket containing the brake unit is placed on the roller conveyor, the worker pushes the frame to the transverse roller conveying equipment, and makes the roller conveyor parallel to the transverse roller conveying equipment; then the elevator is started again, so that the roller conveyor is raised to a position in which the roller conveyor is flush with the transverse roller conveying equipment; and finally, the net basket on the roller conveyor is pushed to the transverse roller conveying equipment.

[0010] Preferably, the frame is further provided with a control box on one side of the top of the frame for controlling the starting of the elevator, two tactile sensors are arranged on the side wall of the control box from top to bottom, the two tactile sensors are electrically connected to the control box respectively, and a sensing sheet is arranged on the roller conveyor and located between the two tactile sensors.

[0011] In the technical scheme, it is to be noted that the control box and the tactile sensors both adopt prior art, and will not be described in detail herein; when the height of the roller conveyor needs to be lowered, the starting of the elevator is controlled by a control button on the control box, the elevator drives the roller conveyor to be lowered, the sensing sheet on the roller conveyor contacts the lowermost tactile sensor, the tactile sensor sends a sensing signal to the control box, and the control box controls the elevator to be closed; similarly, when the height of the roller conveyor needs to be raised, the starting of the elevator is controlled by a control button on the control box, the elevator drives the roller conveyor to be raised, the sensing sheet on the roller conveyor contacts the uppermost tactile sensor, the tactile sensor sends a sensing signal to the control box, and the control box controls the elevator to be closed; in summary, the two tactile sensors, the sensing sheet and the control box can realize semi-automatic lifting of the elevator, and reduce the work burden of the worker.

[0012] Preferably, each of the tactile sensors is mounted on the control box through a mounting shaft arranged along the width direction of the control box, a mounting sheet is sleeved on the mounting shaft, and a clamping device for clamping the mounting sheet is arranged on the mounting shaft, and the tactile sensor is arranged at one end of the mounting sheet.
