[0020] It also includes a cleaning unit 6 installed at the front end of the magnetic vehicle body. The cleaning unit includes a mounting base 61, a fixing plate 62, a telescopic cylinder 63, an L-shaped seat 64, a cleaning block 68, and a mounting mechanism. The mounting base is installed at the front end of the magnetic vehicle body. A fixing plate is installed on top of the mounting base. A telescopic cylinder is installed on the fixing plate. An L-shaped seat is driven and connected to the cylinder rod of the telescopic cylinder. A guide block 65 is provided on the back of the vertical surface of the L-shaped seat, and this guide block slides within a guide groove 66 provided on the mounting base. A cleaning port 67 is provided on the horizontal surface of the L-shaped seat, and the cleaning block is installed at this cleaning port via the mounting mechanism. The cleaning block has an abrasive particle structure at the bottom of the block body; the abrasive particle is alumina or silicon carbide.
[0021] The installation mechanism includes a limiting component, which is symmetrically installed on both the left and right sides of the cleaning port. The limiting component includes a shaft seat 69, a connecting shaft 610, and a screw 611. The shaft seats are arranged opposite each other, and a connecting shaft is connected between the two shaft seats. A screw is installed on the connecting shaft, and the screw is threaded into the internal threaded hole on the side of the cleaning block to limit the cleaning port.
[0022] The installation mechanism includes a snap-fit component 612 and a plug-in component. The snap-fit component is installed at the front end of the cleaning port, and the plug-in component is provided at the rear end of the cleaning port. The snap-fit assembly includes an adapter block 613, a base 6121, a locking member 6122, a pressing block 6123, and a return spring 6124.

Pressing blocks are provided on the outer side of the two locking members, and a return spring is provided between the two pressing blocks and the base. The plug-in assembly includes a plug-in plate 614 and a plug-in slot 615. The plug-in slot is provided at the rear end of the cleaning port, and the plug-in plate is provided at the rear end of the cleaning block. The cleaning block is hung by inserting the plug-in plate into the plug-in slot.
[0023] The magnetic cart body is symmetrically provided with handles 7 on the left and right sides. The handles make it convenient for workers to place the magnetic cart body at the position to be cut on the steel sealing door, and to remove the magnetic cart body from the steel sealing door.
[0024] The principle and usage process of this utility model: Before use, the staff first need to install the plasma cutting machine gun head on the adjustment bracket of the magnetic car body 1, fix the gun head with the second pipe clamp, and fix the cutting position of the gun head with the first pipe clamp. When in use, the staff lifts the handle and places the magnetic car body onto the steel sealing door. Then, the staff moves away from the site and controls the cutting device through the remote control. The operator controls the telescopic cylinder, which drives the L-shaped seat to move downwards. When the cleaning block on the L-shaped seat comes into contact with the steel door, the telescopic cylinder stops working. Then, the operator controls the start of the cutting machine via remote control and controls the magnetic carriage to move on the steel door according to the required cutting operation. During the movement, the cleaning block removes debris and attachments along the path, ensuring the reliability and aesthetics of the steel door cutting. Then, the cutting head cuts the steel door. After cutting in one straight direction, the operator manually assists in changing the direction and starts cutting in another straight direction until the cutting operation is completed. The cleaning block can also be disassembled for cleaning. First, turn the two screws to disengage them from the cleaning block. Then, press the two pressing blocks to open the two locking parts. At this time, the adapter block on the cleaning block is no longer wrapped and is in a releasable state. Then, lift the cleaning block to complete the disassembly of the cleaning block. When the cleaning block needs to be installed after cleaning, the staff first aligns the bottom of the cleaning block with the cleaning port, and inserts the plug plate on the cleaning block into the plug slot. At the same time, the adapter block on the other side will also be locked between the two locking pieces. The two locking pieces can initially position the cleaning block by wrapping the adapter block. At this time, the cleaning block is not stable, so the screws on both sides need to be screwed into the cleaning block 68 to further fix the cleaning block.
