[0030] In order to better implement the utility model, refer to Figure 3 In one embodiment, each slip base 301 is provided with at least two groups of mobile components 2, each group of mobile components 2 is provided with a hydraulic cylinder 201, a piston rod 202 and a sliding track 203, the sliding track 203 is installed on the installation platform, the sliding track 203 is in the form of a groove with the opening upward, to ensure that the lubricating oil dropped into the sliding track 203 will not flow out of the sliding track 203 from the side. A plurality of sliding blocks 204 matched with the sliding track 203 are arranged in the sliding track 203, the sliding track 203 is a dovetail groove, the sliding block 204 has a trapezoidal cross section, the sliding block 203 can slide in the dovetail groove, and the dovetail groove can clamp the sliding block 203 inside, so that the sliding block 203 is not easy to fall off, such as Figure 5The arc-shaped slope is lower than the oil outlet hole 503, so that the lubricating oil flowing out of the oil outlet hole 503 can smoothly flow into the sliding rail 203. The slip assembly 3 is located on the top of the sliding block 204, that is, a plurality of sliding blocks 204 are arranged on the bottom of the slip base 301 respectively, and the slip base 301 is arranged in the sliding rail 203 through the sliding block 204, so that the slip base 301 can slide along the sliding rail 203. The slip base 301 of the slip assembly 3 is connected with one end of the piston rod 202, and the other end of the piston rod 202 extends into the hydraulic cylinder 201. The hydraulic cylinder 201 is connected with the hydraulic pump through the hydraulic pipeline 7. In the embodiment, one slip base 301 is provided with two groups of moving assemblies 2, and the hydraulic cylinder 201 is located on the same side of the slip base 301. When the hydraulic pump transmits the hydraulic oil into the hydraulic cylinder 201 through the hydraulic pipeline 7, the piston rod 202 in the hydraulic cylinder 201 will extend out of the hydraulic cylinder 201, and drive the slip base 301 to extend out of the side of the mounting table. In order to avoid the slip base 301 from being taken out of the sliding rail 203, a limiting device can be arranged in the sliding rail 203, and the sliding length of the slip base 301 in the sliding rail 203 is generally 1 / 3 of the slip base 301, so that the slip teeth 302 can be conveniently replaced and maintained.

[0031] In order to better implement the utility model, refer to Figure 3 And Figure 4 In one embodiment, the sliding rail 203 is provided with a lubricating adjusting assembly 5 away from the slip assembly 3 on one side, and the lubricating adjusting assembly 5 comprises an oil tank 501. The length direction of the oil tank 501 is parallel to the extension direction of the sliding rail 203, and the oil tank 501 is installed on the mounting table. A plurality of oil outlet holes 503 are arranged on the side wall of the oil tank 501 close to the sliding rail 203, and the height of the oil outlet hole 503 on the oil tank 501 is higher than the height of the sliding rail, so that the lubricating oil in the oil tank 501 can flow into the sliding rail along the oil outlet hole 503.

[0032] The lubrication adjusting assembly 5 further comprises an adjusting plate 502, a plurality of first connecting blocks 506 and a plurality of second connecting blocks 507.

In the embodiment, two adjusting holes 504 and two oil outlet holes 503 are arranged. The adjusting plate 502 abuts against the side wall of the oil tank 501 provided with the oil outlet hole 503, and the height of the adjusting plate 502 is consistent with the internal height of the oil tank 501. The two ends of the adjusting plate 502 are connected to the inner wall of the oil tank 501 through elastic members 505. When the elastic members 505 are in a natural state, all the oil outlet holes 503 need to be covered to avoid the lubricating oil in the oil tank 501 flowing into the sliding rail 203 from the oil outlet holes 503 in the initial state of the adjusting plate 502. To avoid the adjusting plate 502 from tilting during sliding, a plurality of elastic members 505 can be additionally arranged at the two ends. The first connecting blocks 506 are arranged in the oil outlet holes 503, one end of the first connecting blocks 506 is connected to the adjusting plate 502, and the other end is fixedly connected to the second connecting blocks 507. The second connecting blocks 507 are installed on the side wall of the slip bowl assembly 3 away from the first connecting blocks 506.

When the elastic members 505 are in a natural state, the distance from the side of the first connecting blocks 506 away from the hydraulic cylinder 201 to the side of the oil outlet holes 503 away from the hydraulic cylinder 201 is greater than the distance from the edge of the adjusting holes 504 away from the hydraulic cylinder 201 to the side of the oil outlet holes 503 close to the hydraulic cylinder 201. When the elastic members 505 are in a natural state, the side of the first connecting blocks 506 close to the hydraulic cylinder 201 abuts against the side wall of the oil outlet holes 503, and at this time, the adjusting holes 504 are misaligned with the oil outlet holes 503.

[0036] When the slip base 301 continues to move out of the mounting table, the tension of the elastic member 505 close to the one end of the adjusting plate 502 gradually increases, and the first connecting block 506 gradually approaches the side wall of the oil outlet hole 503; if the slip base 301 continues to move, the first connecting block 506 and the second connecting block 507 will be separated, the first connecting block 506 is blocked by the oil outlet hole 503 and cannot continue to move with the second connecting block 507; when the first connecting block 506 and the second connecting block 507 are separated, the adjusting plate 502 will return to the original position under the action of the elastic member 505, the elastic member 505 returns to the original length, and the lubricating oil will not flow into the sliding rail 203.

[0037] When the hydraulic cylinder 201 drives the piston rod 202 to retract, the slip base 301 returns to the initial position, and the first connecting block 506 and the second connecting block 507 are connected together again by the magnet sheet.
