[0002] In infrastructure construction, piling is a necessary process. The equipment used for piling is a pile driver. Pile drivers include drop hammer pile drivers, steam hammer pile drivers, diesel hammer pile drivers, hydraulic hammer pile drivers, and spiral pile drivers. Crawler pile drivers refer to pile drivers that use crawler travel systems.

[0021] The outer side of the counterweight telescopic cylinder 31 is fixedly connected to the top of the workbench 2 through a support plate, the bottom of the matching plate 35 is fixedly connected to the top of the workbench 2, and the matching plates 35 are symmetrically arranged along the two sides of the workbench 2, the outer wall of the limiting plate 37 is fixedly connected to the inner wall of the matching plate 35, a slide groove 36 is opened in the wall of the matching plate 35, the inner wall of the slide groove 36 is fixedly connected to the outer wall of the limiting plate 37, the outer wall of the moving wheel 321 is rollingly connected with a guide rail 322, the outer wall of the guide rail 322 is fixedly connected to the top of the workbench 2, and the guide rail 322 is symmetrically arranged along the two sides of the workbench 2.
[0022] The buffer device 4 includes a counterweight baffle 41, the inner wall of which is fixedly connected to a fixed box 45, three groups of fixed boxes 45 are provided, and the inner wall of each group of fixed boxes 45 is slidably connected to a movable rod 43, the bottom of the counterweight baffle 41 is fixedly connected to the top of the workbench 2, the outer wall of the matching plate 35 is fixedly connected to the outer wall of the counterweight baffle 41, the end of the movable rod 43 close to the counterweight member 33 is fixedly connected to a rubber gasket 42, the outer side of the movable rod 43 is fixedly connected to a compression spring 44, and the end of the compression spring 44 away from the rubber gasket 42 is fixedly connected to the inner wall of the fixed box 45.
[0023] Working principle:
[0024] When in use, the mobile crawler 1 is driven to drive the workbench 2 to move, and the workbench 2 drives the pile driving column 5 to move. The position of the counterweight 33 of the crawler pile driver is adjusted by the adjusting device 3, so that the pile driving column 5 can pile on the ground. The buffer device 4 has a shock-absorbing and buffering effect on the counterweight 33.
[0025] In the above process, firstly, according to the center of gravity of the crawler pile driver, the counterweight telescopic cylinder 31 is started to work, and the position of the counterweight member 33 is adjusted by controlling the outward extension distance of the counterweight telescopic cylinder 31 to prevent mechanical failure or safety accidents caused by the forward movement of the center of gravity of the crawler pile driver, so that the counterweight telescopic cylinder 31 pushes the support plate 32 to slide along the direction of the guide rail 322, and the support plate 32 drives the moving wheel 321 to slide on the inner wall of the guide rail 322. The movement of the support plate 32 drives the counterweight member 33 to slide along the direction of the slide groove 36, so that the sliding friction between the support plate 32 and the workbench 2 is converted into the rolling friction between the moving wheel 321 and the guide rail 322, which effectively reduces the friction force of the support plate 32 on the workbench 2, thereby increasing the output force of the counterweight telescopic cylinder 31 to push the counterweight member 33;
[0026] In addition, during the sliding process of the counterweight 33, bolts are used to penetrate between the counterweight 33 and the U-shaped plate 34 to fix them, so as to prevent the counterweight 33 from loosening and falling off. The movement of the counterweight 33 drives the U-shaped plate 34 to slide in the slide groove 36, and the bottom of the U-shaped plate 34 rolls on the ball 371. The rolling ball 371 rotates in the arc groove on the inner wall of the limiting plate 37, so that the sliding friction between the U-shaped plate 34 and the matching plate 35 is transformed into the rolling friction between the U-shaped plate 34 and the ball 371, thereby reducing the friction force of the matching plate 35 on the U-shaped plate 34. The rolling friction between the ball 371 and the U-shaped plate 34 reduces the friction resistance of the sliding of the counterweight 33.
[0027] In the process of the counterweight 33 approaching the counterweight baffle 41, the surface of the counterweight 33 contacts the rubber gasket 42, and the counterweight 33 squeezes the rubber gasket 42. The squeezed rubber gasket 42 drives the movable rod 43 to slide along the axial direction of the fixed box 45. The sliding of the movable rod 43 compresses the compression spring 44, and the buffer device 4 is used to dampen the sliding counterweight 33, thereby reducing the damage caused by the direct collision between the counterweight 33 and the counterweight baffle 41.
