Description

Technical Field

[0001] This utility model relates to the field of polishing device technology, and in particular to a pantograph carbon slide plate polishing device. Background Technology

[0002] The pantograph carbon sliding plate is a key component for electric locomotives and electric multiple units (EMUs) to obtain electrical energy from the overhead contact line. Installed on top of the pantograph, it directly contacts the contact wire. During train operation, it introduces electrical energy from the contact wire into the train, providing power. When the train is in motion, the pantograph rises, making close contact between the carbon sliding plate and the contact wire. Due to the excellent conductivity of the carbon sliding plate, the current in the contact wire is conducted through the carbon sliding plate and pantograph to the electrical equipment inside the train, thus converting electrical energy into train power and propelling the train. However, after use, many dents will appear on the surface of the pantograph carbon sliding plate. In order to ensure the stable operation of electric locomotives and electric multiple units, it is necessary to grind the dents on the surface of the pantograph carbon sliding plate, which requires the use of a grinding device. However, the existing grinding device requires the pantograph carbon sliding plate to be disassembled before it can be ground. This operation is time-consuming and labor-intensive, reducing the efficiency of grinding the pantograph carbon sliding plate. Summary of the Invention

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0013] Please see Figure 1 - Figure 3 This utility model provides a technical solution: A pantograph carbon strip polishing device includes a frame 1 with rectangular openings at both ends for easy gripping by the operator, facilitating the handling of the polishing device. Rectangular cavities 14 are provided at both ends of the frame 1, each containing a clamping mechanism. These clamping mechanisms allow for easy installation of the polishing device on the pantograph carbon strip, eliminating the need to disassemble the strip and improving polishing efficiency. Furthermore, the device can be installed on different pantograph carbon strips, enhancing its versatility. An electric belt sander 6 is slidably mounted inside the frame 1 via a stabilizing component. The electric belt sander 6 can be powered by a lithium battery or connected to an external power source via a wire. A dust collection component is provided on the side of the electric belt sander 6. The use of the dust collection component facilitates the absorption of carbon powder generated during the sanding of the pantograph carbon slide plate, preventing carbon powder from adsorbing onto surrounding electrical components and causing short circuits. It also prevents carbon powder from polluting the surrounding environment, which is beneficial to the protection of the atmospheric environment.

[0014] In this utility model, the clamping mechanism includes a support plate 13 fixedly connected inside a rectangular cavity 14. A bidirectional lead screw 11 is rotatably mounted on the support plate 13, and both ends of the bidirectional lead screw 11 extend movably out of the rectangular cavity 14 and are fixedly connected to a rotating handle 8. A gripper 12 is threadedly connected to the outer wall of the bidirectional lead screw 11, and a rubber pad (not shown in the figure) is also provided on the gripper 12 to improve the flexibility of the gripper 12, avoid damage to the pantograph carbon plate, and help protect the pantograph carbon plate; and the gripper 12 is slidably arranged with the rectangular cavity 14. In this utility model, the stabilizing component includes a connecting frame 3 disposed at both ends of the electric belt sander 6, a connecting shaft 2 fixedly connected to the connecting frame 3, and a guide rail 7 disposed on the inner wall of the frame 1. A slider 10 is slidably disposed on the guide rail 7, and a rotating arm 9 is rotatably disposed on the slider 10, and the rotating arm 9 is rotatably disposed with the connecting shaft 2. The use of the stabilizing component facilitates the support of the electric belt sander 6, thereby facilitating stable sanding of the pantograph carbon slide plate.

[0015] In this utility model, the dust collection component includes a dust collector 4 disposed on the side of the electric belt sander 6, with the air inlet of the dust collector 4 aligned with the sanding position of the electric belt sander 6, and a dust collection bag 5 disposed on the dust collector 4; by using the dust collector 4, it is easy to absorb the carbon powder generated during sanding into the dust collection bag 5, thereby facilitating the collection of carbon powder, avoiding carbon powder pollution of the surrounding atmospheric environment, and contributing to the protection of the surrounding atmospheric environment.

[0016] Working principle: When using this utility model to grind the pantograph carbon plate, the grinding device is first installed on the pantograph carbon plate. Specifically, the two jaws 12 are placed at both ends of the pantograph carbon plate. Then, the rotating handle 8 is rotated, which drives the bidirectional lead screw 11 to rotate, thereby driving the two jaws 12 to move relative to each other. The grinding device is fixedly installed on the pantograph carbon plate by the clamping force between the two jaws 12. Next, turn on the electric belt sander 6, hold the handle of the electric belt sander 6 and push it to move. The electric belt sander 6 slides on the surface of the pantograph carbon plate to sand the pantograph carbon plate. When the indentation on the pantograph carbon plate is deep, the operator needs to press the electric belt sander 6 firmly. When the indentation on the pantograph carbon plate is shallow, the operator needs to press the electric belt sander 6 lightly to achieve the sanding of the pantograph carbon plate. During the polishing process, the generated toner powder is collected by the vacuum cleaner 4 into the dust bag 5, thus collecting the toner powder and preventing it from polluting the surrounding atmosphere. After the pantograph carbon slide plate has been polished, turn the handle 8 to move the two grippers 12 away, thus removing the polishing device from the pantograph carbon slide plate.

[0017] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
