[0035] As shown, Figure 4 the connecting rod 6 is rotatably connected inside the sliding frame 5; a torsional spring is installed at the rotating shaft of the connecting rod 6; during the mutual extrusion of the connecting rod 6 and the inner side wall of the steel beam, the connecting rod 6 can be effectively protected by being arranged inside the sliding frame 5 and being deflectable, so that the connecting rod 6 will not be broken when the inner width of the steel beam is different.

[0036] As shown, Figure 2 the top of the moving wheel 3 is fixedly connected with a positioning rod 16; the positioning rod 16 is slidably connected inside the moving frame body 1; a blocking block 17 is fixedly connected to the end of the positioning rod 16; during the sliding of the wheel frame 4 inside the moving frame body 1, the wheel frame 4 is less likely to tilt and slides more stably by the limitation of the moving frame body 1 to the positioning rod 16; meanwhile, the wheel frame 4 is stopped by the blocking block 17 at the end of the positioning rod 16, so that the wheel frame 4 is effectively prevented from falling out of the moving frame body 1.

[0037] As shown, Figures 3-4 the side wall of the connecting rod 6 is fixedly connected with a scraper 18; the scraper 18 is arranged at a position corresponding to the rotating direction of the stabilizing wheel 7; the end of the scraper 18 is in contact with the side wall of the stabilizing wheel 7; when the adsorbing magnetic block 701 is in contact with the inner side wall of the steel beam, the iron powder remaining on the inner side wall of the steel beam is easily adsorbed by the adsorbing magnetic block 701; the iron powder and other impurities on the surface of the adsorbing magnetic block 701 are scraped and cleaned by the scraper 18 arranged on the side wall of the connecting rod 6, so that the iron powder is effectively prevented from adhering to the surface of the adsorbing magnetic block 701 and affecting the magnetism of the adsorbing magnetic block 701.

[0038] As shown, Figure 8 the outer side wall and the end of the threaded rod 9 are fixedly connected with anti-dropping blocks 19; the anti-dropping blocks 19 are arranged at positions corresponding to the moving frame body 1; during the rotation of the threaded rod 9 inside the moving frame body 1, the anti-dropping blocks 19 are limited by the moving frame body 1, so that the threaded rod 9 is effectively prevented from tilting during the rotation, and the rotation of the threaded rod 9 is more stable.

[0039] The mobile frame body 1 and the anti-off block 19 are provided with a plurality of rolling balls 20; the side walls of the rolling balls 20 are in contact with the side walls of the mobile frame body 1 and the anti-off block 19; during work, when the anti-off block 19 rotates in the interior of the mobile frame body 1, the rolling balls 20 arranged between the mobile frame body 1 and the anti-off block 19 can change the sliding friction between the mobile frame body 1 and the anti-off block 19 into rolling friction, so that the wear between the mobile frame body 1 and the anti-off block 19 is less.

[0040] As shown in Figure 8 The side wall of the push block 8 is provided with a rubber pad 21; the rubber pad 21 is arranged at a position corresponding to the push block 8; during work, when the push block 8 pushes and supports the sliding frame 5, the friction between the push block 8 and the sliding frame 5 is greater, so that the supporting effect of the push block 8 on the sliding frame 5 is better.

[0041] During work, when the steel beam needs to be welded, the mobile frame body 1 can be released from one end of the steel beam, and then the mobile frame body 1 can be moved by the mobile wheels 3 to the welding point, and then the steel beam can be welded by the welding machine 2; if the worker cannot follow, a camera can be installed on the equipment to monitor the work of the equipment, so that the work of the equipment is more convenient; during the movement of the mobile frame body 1, when the mobile frame body 1 encounters an obstacle, the mobile wheels 3 will drive over the top of the obstacle by friction and the thrust of the subsequent mobile wheels 3, so that the equipment can continue to move forward; through the obstacle, during the movement of the mobile frame body 1 through the obstacle, the wheel frame 4 will retract into the interior of the mobile frame body 1, so that the movement of the mobile frame body 1 is more stable, so that the welding process can be carried out better, effectively solving the problem that the interior of the steel beam is blocked and the welding equipment is easily blocked; at the same time, the steel beam can be welded by the welding equipment, which can effectively relieve the pressure of the operator and make the welding work easier.

[0042] When the mobile frame body 1 drives into the interior of the steel beam, the push block 8 can slide away from the rotating disc 10 by rotating the rotating disc 10 and cooperating the threads of the rotating disc 10 and the push block 8, and then the push block 8 will push the sliding frame 5 to make the sliding frame 5 slide to the outside of the mobile frame body 1, and then the connecting rod 6 will be pressed against the inner side wall of the steel beam, so that the friction between the connecting rod 6 and the inner side wall of the steel beam is increased, so that the mobile frame body 1 can move stably in the interior of the steel beam and the welding machine 2 can weld the steel beam; at the same time, the adsorbing magnetic block 701 is arranged on the side wall of the stabilizing wheel 7, and the inner side wall of the steel beam can be adsorbed by the adsorbing magnetic block 701, so that the friction between the stabilizing wheel 7 and the steel beam is greater, so that the stabilizing effect of the stabilizing wheel 7 on the mobile frame body 1 is better.

[0043] In the process of welding machine 2 welding steel beam, the welding slag is easy to fly out with high heat, at this time, the exhaust fan can be started, so that the exhaust fan can suck the welding slag in the air through the connecting pipe 13 and the collection disc 11, and guide into the inside of the water storage tank 14 through the connecting pipe 13, and cool the welding slag, at the same time, the water storage tank 14 is arranged at the corner of the moving frame body 1, which can increase the counterweight of the moving frame body 1, so that the moving wheel 3 can be more stable when passing through the barrier.

[0044] In the process of the water storage tank 14 counterweighting the moving frame body 1, the ball joint of the connecting ball 15 can make the weight of the water storage tank 14 always downward, so that the counterweight effect of the water storage tank 14 is better.

[0045] When the connecting rod 6 is extruded with the inner side wall of the steel beam, the connecting rod 6 arranged in the sliding frame 5 can be deflected, which can effectively avoid the situation that the width of the steel beam is different, which may cause the connecting rod 6 to break, so as to protect the connecting rod 6.

[0046] When the wheel frame 4 slides in the moving frame body 1, the positioning rod 16 of the moving frame body 1 can limit the wheel frame 4 to slide, so that the wheel frame 4 is less inclined during sliding, and the sliding of the wheel frame 4 is more stable, and the blocking block 17 is arranged at the end of the positioning rod 16, which can stop the wheel frame 4 and effectively avoid the situation that the wheel frame 4 falls out of the moving frame body 1.

[0047] When the adsorbing magnetic block 701 contacts with the inner side wall of the steel beam, the iron powder remaining on the inner side wall of the steel beam is easy to be adsorbed by the adsorbing magnetic block 701, and the scraper 18 is arranged on the side wall of the connecting rod 6, which can scrape and clean the iron powder and other impurities on the surface of the adsorbing magnetic block 701, so as to effectively avoid the situation that the iron powder adheres to the surface of the adsorbing magnetic block 701, which may affect the magnetism of the adsorbing magnetic block 701.

[0048] When the threaded rod 9 rotates in the moving frame body 1, the anti-coming-off block 19 of the moving frame body 1 can limit the threaded rod 9 to rotate, so that the threaded rod 9 is less inclined during rotation, and the rotation of the threaded rod 9 is more stable.

[0049] When the anti-coming-off block 19 rotates in the moving frame body 1, the rolling ball 20 is arranged between the moving frame body 1 and the anti-coming-off block 19, which can change the sliding friction between the moving frame body 1 and the anti-coming-off block 19 into rolling friction, so that the wear between the moving frame body 1 and the anti-coming-off block 19 is less.

[0050] When the pushing block 8 pushes the sliding frame 5, the friction between the pushing block 8 and the sliding frame 5 is larger, so that the pushing block 8 can better support the sliding frame 5.
