Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a workbench for cleaning front and rear surfaces of a vehicle.

[0002]

[Prior art]

 When cleaning the front and rear surfaces of a train or the like, it is necessary to install a workbench and a ladder on which a worker rests to perform the cleaning work. However, the workbench and the ladder are extremely unstable, and there is a risk that accidents such as the fall of workers may occur. Therefore, a workbench has been developed that has a workbench that moves forwards and backwards on the side of the track of a train so that work can be performed in a stable state.

[0003]

[Problems to be solved by the device]

 However, the conventional workbench described above has a drawback in that it is mechanically complicated and expensive. In addition, it was necessary to provide one workbench for each track of the electric train, which had the drawback of being inefficient. The present invention aims to solve the above-mentioned problems of the prior art.

[0004]

[Means and Actions for Solving the Problems]

 In order to achieve the above object, a workbench for cleaning the front and rear surfaces of a vehicle according to the present invention is horizontally rotatably mounted on a side of a traveling road of a vehicle to be cleaned, and is horizontally movable when cleaning the front and rear surfaces of the vehicle to be cleaned. It is characterized in that it is installed so as to rotate and cross the traveling path, and is located so as to face the front or rear surface of the vehicle to be cleaned. By rotating the workbench on the front or rear surface of the vehicle to be washed, a relatively simple structure can be achieved. Also, the workbench can be made stable. By mounting such a workbench horizontally rotatable between the two running paths of the vehicle to be washed, it is possible to wash the vehicles on the two running paths with one working table. It is possible to improve efficiency and reduce costs.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1 is a plan view thereof, and FIG. 2 is an elevation view thereof. A vehicle to be cleaned X and a vehicle to be cleaned X'arrive on the traveling path A and the traveling path A, respectively, and the front surface and the rear surface thereof are cleaned. The vehicles to be cleaned X and X'are rail vehicles such as trains in this embodiment. A base 5 is installed between the travel path A and the travel path A ', and the workbench 1 is installed there. The workbench 1 can be rotated by a rotation support portion 2.

When the workbench 1 is not used, the workbench 1 is housed between the travel path A and the travel path A ′, and extends downward from the rotation support portion 2 in the drawing, and the tip is placed on the platform 3. It has become. When cleaning the front surface or the rear surface of the vehicle to be cleaned X, X ', the workbench 1 is rotated about 90 ° and installed at a position crossing the traveling path A or A'. Outside the traveling paths A and A '(on the side opposite to the base 5), there are provided platforms 3a and 3b for receiving the tip of the workbench 1, respectively. It is designed to be placed on the tip of the platform 3a or 3b so that the cleaning work can be performed.

The elevation view of FIG. 2 shows a state in which the workbench 1 is rotated toward the platform 3a so that the front surface of the vehicle X to be cleaned on the right side of the drawing can be washed. The workbench 1 is provided with a safety fence 4 and is configured to ensure the safety of the worker.

3 and 4 are enlarged views of the tip portion of the workbench 1 and the platform 3 (3a and 3b have the same structure). The workbench 1 is provided with three wheels 10 arranged in the width direction at the tip end thereof. The wheel 10 passes over the inclined plate 30 provided on the platform 3 and abuts the stopper 31. It is designed to be placed on the platform 3. The combination of the wheel 10 and the inclined plate 30 ensures that the tip of the workbench 1 is reliably placed on the platform 3 even if the tip of the workbench 1 is slightly lowered due to gravity.

FIG. 5 is a cross-sectional view showing a drive unit of the rotation support unit 2. The rotation support portion 2 is rotatably mounted on a bearing 50 mounted on the base 5, a rotation shaft 20 extends downward from the center of the rotation support portion 2, and a sprocket 21 is provided below the base 5. It is adapted to be rotationally driven by a motor 22 via the motor. An operating piece 24 is mounted on the rotary shaft 20, and when the operating piece 24 approaches the proximity switch 23, the turning angle of the turning support portion 2 is detected to control the on / off of the motor 22. ing.

In the above-described configuration, in the state where the workbench 1 is stored on the platform 3 at the center, the wash target vehicles X and X'can be normally run on the travel paths A and A '. When cleaning the front surface or the rear surface of the vehicle to be cleaned X, X ', the vehicle to be cleaned X, X'is stopped at a predetermined position, and the workbench 1 is rotated toward the platform 3a or 3b. Then, when the front end of the workbench 1 is placed on the platform 3a or 3b, the workbench 1 is installed on the front surface or the rear surface of the vehicle to be cleaned as shown in FIG. This work table 1 is not a ladder or a temporary work table, but is securely held by the rotation support portion 2 and the platform 3, so that it is extremely stable and safe work is possible. In addition, the safety fence 4 enables safer work. In addition, one workbench 1 can be selectively used for two roads A and A ′, the number of workbench 1 can be reduced, and the installation space can be saved. Is. Further, since the workbench 1 is adapted to rotate, the structure is relatively simple.

[0011]

[Effect of device]

 As described above, the workbench for cleaning the front and rear surfaces of the vehicle of the present invention is capable of performing safe work, has a relatively simple structure, and requires only one to be installed on two traveling paths. It is possible to reduce the installation cost and save the installation space.
