When using the crossbeam of the frame, weld the connecting ring 2 to the top of the crossbeam main body 1, then place the upper frame on the top of the rotating disc 3 rotatably arranged inside the connecting ring 2, and then place the crawlers on both side surfaces of the crossbeam main body 1, so that the excavator can be well assembled together.

[0028] Refer to Figure 2 and Figure 3, the limiting device 4 includes a connecting rod 401. The bottom of the connecting rod 401 is threadedly inserted into the bottom of the connecting ring 2, and the connecting rod 401 is slidably inserted into the top of the crossbeam main body 1. When using the limiting device 4, threadedly insert the connecting rod 401 into the bottom of the connecting ring 2, and then make the connecting rod 401 pass through the top of the crossbeam main body 1. This can, to a certain extent, prevent the connecting ring 2 from moving during welding and affecting the welding. A support plate 402 is fixedly connected to the bottom of the connecting rod 401. A circular rod 403 is uniformly fixedly connected to one side of the support plate 402. A connecting frame 404 is rotatably sleeved on the surface of the circular rod 403. A limiting frame 405 is fixedly connected to the bottom of the crossbeam main body 1. A rectangular plate 406 is slidably connected to the inner wall of the limiting frame 405. A chute 407 is opened on one side of the rectangular plate 406. A clamping plate 409 is slidably connected to the inner wall of the chute 407. The clamping plate 409 is slidably connected to the inner wall of the connecting frame 404. Manually control the connecting frame 404 to rotate on the surface of the circular rod 403, so that one side of the connecting frame 404 is attached to the bottom of the connecting rod 401. Then slide the rectangular plate 406 into the limiting frame 405, and then control the clamping plate 409 to slide into the connecting frame 404. This can well limit the connecting rod 401 inside the crossbeam main body 1. A first spring 408 is fixedly connected to one side of the inner wall of the chute 407. One end of the first spring 408 close to the inner wall of the chute 407 is fixedly connected to one side of the clamping plate 409. The clamping plate 409 is well limited inside the connecting frame 404 by the first spring 408 pressing the clamping plate 409 away from the chute 407. A rotating rod 410 is fixedly connected to one side of the support plate 402. A baffle 411 is rotatably sleeved on the surface of the rotating rod 410. An L-shaped plate 412 is slidably inserted through one side of the rotating rod 410. A damping rod 413 is fixedly connected to one side of the L-shaped plate 412. One end of the damping rod 413 is fixedly connected to one side of the support plate 402. A second spring 414 is sleeved on the surface of the damping rod 413. One end of the second spring 414 is fixedly connected to one side of the L-shaped plate 412. One end of the second spring 414 close to the damping rod 413 is fixedly connected to one side of the support plate 402. Manually control the baffle 411 to rotate on the surface of the rotating rod 410 so that the baffle 411 is arranged on one side of the connecting frame 404. Then insert the L-shaped plate 412 into one side of the support plate 402. The baffle 411 is well limited on one side of the connecting frame 404 by the second spring 414 pulling the L-shaped plate 412 towards the support plate 402.

[0029] Refer to Figure 4, the lubrication device 5 includes a roller 504. On one side of the inner wall of the connecting ring 2, a receiving groove 501 is provided. On one side of the connecting ring 2, a circular groove 510 is provided. Through the circular groove 510, the lubrication device 5 can be well arranged inside the connecting ring 2. The inner wall of the receiving groove 501 is slidably connected with a U-shaped plate 502. Inside the inner wall of the U-shaped plate 502, a positioning rod 503 is fixedly connected. The roller 504 is rotatably sleeved on the surface of the positioning rod 503. When using the lubrication device 5, lubricating oil is arranged on the surface of the roller 504. Since the surface of the roller 504 is provided with a cloth surface, the lubricating oil can adhere to the surface of the roller 504. The roller 504 is pressed against one side of the rotating disk 3. When the rotating disk 3 rotates, the lubricating oil can be well applied to the connection between the rotating disk 3 and the connecting ring 2, which can play a good lubricating role. One side of the U-shaped plate 502 is inserted with a connecting pipe 505. The connecting pipe 505 slidably penetrates and is inserted on one side of the receiving groove 501. One end of the connecting pipe 505 close to the U-shaped plate 502 is fixedly connected with a rubber cylinder 506. One end of the connecting pipe 505 far from the U-shaped plate 502 is provided with a rubber plug 507. Through the connecting pipe 505, lubricating oil can be arranged on the surface of the roller 504. The surface of the connecting pipe 505 is evenly fixedly connected with protrusions 508. A rubber ring 509 is slidably sleeved on the surface of the connecting pipe 505. The rubber ring 509 is arranged on the inner wall of the circular groove 510. When the lubrication device 5 is not in use, the U-shaped plate 502 is made to closely adhere to one side of the inner wall of the receiving groove 501, and then the rubber ring 509 is arranged on the surface of the connecting pipe 505, and then the rubber ring 509 is arranged inside the circular groove 510. In this way, the roller 504 can be well separated from the rotating disk 3, and the connecting pipe 505 can be well restricted inside the connecting ring 2.

[0030] Working principle: When using the frame crossbeam, weld the connecting ring 2 to the top of the crossbeam main body 1, then place the upper frame on the top of the rotating disk 3 rotatably arranged inside the connecting ring 2, and then set the crawlers on both side surfaces of the crossbeam main body 1, so that the excavator can be assembled well. When using the limiting device 4, thread the connecting rod 401 into the bottom of the connecting ring 2, then make the connecting rod 401 pass through the top of the crossbeam main body 1, and then manually control the connecting frame 404 to rotate on the surface of the round rod 403, so that one side of the connecting frame 404 is in contact with the bottom of the connecting rod 401. Then slide the rectangular plate 406 into the limiting frame 405, and then control the clamping plate 409 to slide into the connecting frame 404. Manually control the baffle plate 411 to rotate on the surface of the rotating rod 410, so that the baffle plate 411 is arranged on one side of the connecting frame 404. Then insert the L-shaped plate 412 into one side of the support plate 402, and pull the L-shaped plate 412 towards the support plate 402 by the second spring 414. In this way, the baffle plate 411 can be well restricted on one side of the connecting frame 404, and the connecting rod 401 can be well restricted inside the crossbeam main body 1, which can avoid the movement of the connecting ring 2 during welding and affect the welding to a certain extent. When using the lubricating device 5, the lubricating oil can be set on the surface of the roller 504 through the connecting pipe 505. Because the surface of the roller 504 is provided with a cloth surface, the lubricating oil can adhere to the surface of the roller 504. Squeeze the roller 504 against one side of the rotating disk 3. When the rotating disk 3 rotates, the lubricating oil can be well applied to the connection between the rotating disk 3 and the connecting ring 2, which can play a good lubricating role. When not using the lubricating device 5, make the U-shaped plate 502 close to one side of the inner wall of the receiving groove 501, and then set the rubber ring 509 on the surface of the connecting pipe 505, and then set the rubber ring 509 into the round groove 510. In this way, the roller 504 can be well separated from the rotating disk 3, and the connecting pipe 505 can be well restricted inside the connecting ring 2.
