[0022] Compared with the prior art, the beneficial effects of the present application are:

[0023] 1. In use, a pit is dug in the middle position of a group of anchor cables, the underground assembly is buried in the pit, and then the positions of the moving supports are adjusted in turn to be close to the tensioning ends of the anchor cables, the tensioning ends of the anchor cables are fixed through the clamping mechanism, and then the anchor cables can be pulled by the tensioning hydraulic cylinders, so that the anchor cables are tensioned to a suitable prestress, and then the anchor cables are fixed, which is simple and convenient to use, and the positions of the moving supports can be adjusted to tension and fix the anchor cables at different positions;

[0024] 2. Through the design of the height adjusting mechanism, the height of the moving support can be adaptively adjusted through the height adjusting mechanism, so that the device can adapt to different installation conditions, and when the four second threaded rods are synchronously rotated, the second threaded rods and the second threaded sleeves are threadedly matched, so as to drive the lifting support seat to move up and down, thereby achieving the purpose of adjusting the height of the lifting support seat.

[0025] 3. Due to the presence of the incomplete gear, there are continuously distributed sector-shaped meshing teeth less than 180 degrees on the incomplete gear. When the incomplete gear rotates to the state where the meshing teeth are engaged with the first ring teeth on the disc, it can ensure that the incomplete gear will not mesh with the second ring teeth on the elliptical wheel, and vice versa. During the rotation of the incomplete gear, it can drive the elliptical wheel and the disc to rotate independently in sequence. By selecting appropriate part sizes, it can be maintained that the incomplete gear drives half a revolution for every revolution. When the long axis of the elliptical wheel is facing the locking pin, it can overcome the elastic force of the elastic telescopic rod and push the locking pin into the positioning hole, so that the guide locking plate cannot move up and down, thereby achieving the purpose of locking the height of the lifting support seat. As the incomplete gear is driven to rotate by the first handle, it can switch continuously between the locked and unlocked states.

[0026] 4. Each rotation of the incomplete gear drives the disc and the first spur gear to rotate by an angle. By selecting appropriate part sizes, the meshing of the first spur gear and the fourth spur gear is ensured to drive the second threaded rod to rotate several times and drive the lifting support to move a distance in the vertical direction. This distance is exactly the same as the distance between two adjacent positioning holes, so that it can move upwards intermittently by a distance. During the gap of movement, the elliptical wheel will rotate half a revolution, thereby achieving the effect of locking and unlocking.

[0027] 5. When adjusting the height, simply rotate the first handle continuously. During this process, the lifting support will first rise a certain distance and then stop. Then, the elliptical wheel will rotate 90 degrees, locking the height of the lifting support. When you continue to rotate the first handle, the elliptical wheel will continue to rotate 90 degrees, releasing the height lock of the lifting support. Then, the lifting support will continue to rise a certain distance, thus achieving continuous unidirectional adjustment. After the adjustment is completed, the height can also be locked. The operation is simple and convenient, requiring only continuous rotation of the first handle, making the installation of the device more convenient and efficient.

[0028] 6. Through the locking drive design, when one of the third threaded rods is rotated by the third handle, the meshing of the third spur gear and the transmission gear ring will drive the other third threaded rods to rotate synchronously. Then, through the cooperation of the third threaded rod and the third threaded sleeve, the arc-shaped clamping parts can be moved along the third slide rail. This allows for quick manual adjustment of the relative distance between the arc-shaped clamping parts, thus enabling the cable to be locked and released quickly. Attached Figure Description

[0052] When the four second threaded rods 401 rotate synchronously, the lifting support base 4 can be driven to move up and down due to the threaded cooperation between the second threaded rod 401 and the second threaded sleeve 201, so that the height of the lifting support base 4 is adjusted;

[0053] The two sides of the support outer frame 301 are fixed with horizontally arranged auxiliary guide supports 302, the bottom end of the lifting support base 4 is fixed with vertically arranged guide locking plates 4014 on both sides, the bottom end of the guide locking plate 4014 is movably penetrated through the auxiliary guide support 302 through a guide gap, a plurality of positioning insertion holes 4015 are equidistantly arranged on the guide locking plate 4014 from top to bottom, the two sides of the support outer frame 301 are fixed with horizontally arranged locking pins 303, the locking pins 303 are correspondingly matched with the positioning insertion holes 4015, and the outer wall of the support outer frame 301 is further fixed with elastic extension rods 306, and the movable end of the elastic extension rod 306 is fixed with the locking pin 303;

[0054] The elastic telescopic rod 306 is in a relaxed state, and pulling the locking bolt 303 moves towards the inside of the support outer frame 301, so that the locking bolt 303 does not contact the guide locking plate 4014. When the lifting support seat 4 moves up and down, the guide locking plate 4014 follows the lifting movement, and the sliding fit of the auxiliary guide bracket 302 and the guide locking plate 4014 plays an auxiliary guiding role for the movement of the lifting support seat 4.

[0055] The top end of the connecting support seat 2 is rotatably installed with a vertical rotating shaft 304, the top end of the vertical rotating shaft 304 is fixed with an oval wheel 305, the edge of the oval wheel 305 is in contact with one side of the locking bolt 303, the lifting support seat 4 is rotatably installed with a prismatic sleeve 4012, the outside of the prismatic sleeve 4012 is fixed with a first spur gear 4013, the outside of the second threaded rod 401 is fixed with a fourth spur gear 4011, the four fourth spur gears 4011 are arranged around the first spur gear 4013 and mesh with the first spur gear 4013, the support outer frame 301 is rotatably installed with a horizontally arranged horizontal rotating shaft 307, one end of the horizontal rotating shaft 307 is fixed with a first handle, the other end of the horizontal rotating shaft 307 is fixed with an incomplete gear 308, the support outer frame 301 is rotatably installed with a prismatic rod 801 through a connecting piece 8, the top end of the prismatic rod 801 extends into the prismatic sleeve 4012, the bottom end of the prismatic rod 801 is fixed with a disc 802, the bottom end of the disc 802 is provided with a first annular tooth 8021, the top end of the oval wheel 305 is provided with a second annular tooth 3051, the first annular tooth 8021 and the second annular tooth 3051 are correspondingly meshed with the incomplete gear 308;

The incomplete gear 308 can independently drive the oval wheel 305 and the disc 802 to rotate in sequence during rotation. By selecting appropriate part sizes, the incomplete gear 308 can drive half a circle to rotate every revolution. When the major axis of the oval wheel 305 is directed towards the locking bolt 303, the elastic force of the elastic telescopic rod 306 can be overcome to push the locking bolt 303 into the positioning hole 4015, so that the guide locking plate 4014 cannot move up and down, thereby achieving the purpose of locking the height of the lifting support seat 4.

[0058] When adjusting the height, only the first handle needs to be continuously rotated, and in this process, the lifting support base 4 will first rise by a distance, then stop, then the oval wheel 305 rotates by ninety degrees, so that the height of the lifting support base 4 is locked, and when the first handle continues to be rotated, the oval wheel 305 continues to rotate by ninety degrees, and the height of the lifting support base 4 is unlocked, and then the lifting support base 4 continues to rise by a distance, so as to achieve the purpose of continuous one-way adjustment, and after the adjustment is completed, the height can also be locked, and only the first handle needs to be continuously rotated during operation, which is simple and convenient to use, so that the device is more convenient and efficient.
