[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides two technical solutions:

[0025] Figure 1 to Figure 2 The first embodiment is shown: an anchor withdrawal device based on a tensioning jack 1, comprising a jack 1, an anchor withdrawal assembly 2 installed above the jack 1, an outer wall of the anchor withdrawal assembly 2 being rotatably connected to a hammer handle 3 via an axle pin, a hammer head 4 being inserted at the upper end of the hammer handle 3, the hammer head 4 being positioned on the hammer handle 3 via a snap assembly installed on the hammer handle 3, and a driving assembly for causing the hammer head 4 to hammer the anchor cable lock is installed on the outer wall of the anchor withdrawal assembly 2.

[0026] The driving assembly includes a motor 5, a support plate 6 is fixedly connected to the outer wall of the anchor removal assembly 2, the motor 5 is fixedly connected above the support plate 6, a rotating rod 7 is fixedly connected to the output end of the motor 5, the rotating rod 7 is opposite to the hammer handle 3, and a first spring 8 is fixedly connected to the lower end of the hammer handle 3, and the end of the first spring 8 facing away from the hammer handle 3 is fixed to the outer wall of the anchor removal assembly 2.

[0027] A reinforcing plate 14 is fixedly connected below the supporting plate 6 , and one end of the reinforcing plate 14 facing away from the supporting plate 6 is fixed to the anchor withdrawal assembly 2 .

[0028] This application sets up a motor 5, a support plate 6, a first spring 8, a rotating rod 7, a hammer head 4 and a hammer handle 3, so that when the anchor cable lock cannot fall naturally during the anchor withdrawal work, the motor 5 can be used to directly drive the hammer head 4 to knock on the lock, forcing the lock core in the lock to loosen and fall, without manual hammering, which is more convenient and practical.

[0029] Figures 2 to 3A second embodiment is shown, and its main difference from the first embodiment is that: the snap assembly includes a pull rod 9, and the upper end of the hammer handle 3 is slidably connected to the pull rod 9 through a sliding hole, and the upper end of the hammer handle 3 extends outward to form two support blocks 10, and the end of the pull rod 9 close to the anchor withdrawal assembly 2 is fixedly connected to a second spring 11, and the end of the second spring 11 close to the hammer handle 3 is fixed to the outer wall of the hammer handle 3, and the end of the pull rod 9 facing away from the spring is fixedly connected to a clamping block 12, and a clamping groove 13 is provided on the side of the hammer head 4 close to the clamping block 12, and the clamping block 12 is clamped in the clamping groove 13.

[0030] The block 12 is arranged in a trapezoidal shape.

[0031] The outer edge of the slot 13 is rounded.

[0032] This application provides a snap assembly so that the hammer head 4 can be removed when not in use, thereby reducing the weight of the device. The hammer head 4 is easily worn out by hammering, and the snap assembly makes the replacement of the hammer head 4 faster and more convenient.

[0033] Working principle:

[0034] The jack 1 and the anchor withdrawal assembly 2 adopt the anchor cable tensioning jack and anchor withdrawal device in CN 213540441 U, which are prior arts and will not be described in detail.

[0035] When the anchor withdrawal work begins, it is necessary to align the center of the anchor withdrawal component 2 with the center of the anchor cable lock, drive the jack 1 to make the anchor withdrawal component 2 push the anchor cable lock shell upward, so that the anchor cable shell is pushed upward, and after the anchor cable lock shell is pushed up, the lock core of the anchor cable lock naturally falls into the anchor withdrawal component 2, and then the lock shell and the lock support plate are removed to complete the anchor cable lock withdrawal.

[0036] When the turning rod 7 rotates one circle, the lower end of the hammer handle 3 is pressed once, and the first spring 8 is squeezed at the same time. When the lower end of the hammer handle 3 is pressed, the hammer head 4 at the upper end of the hammer handle 3 is away from the anchor withdrawal component 2, until the turning rod 7 moves away from the anchor withdrawal component 2, the pressure ends, and the first spring 8 rebounds quickly and makes the hammer handle 3 return to its original position quickly, and the upper end of the hammer handle 3 drives the hammer head 4 to knock on the anchor cable lock; the turning rod 7 completes one knocking each time it rotates one circle, and the anchor cable lock is knocked back and forth in this way, so that the lock core is loosened and falls off.

[0037] During long-term use, the hammer head 4 is prone to wear and tear. The snap assembly can be used to conveniently replace the hammer head 4. When the hammer head 4 is not needed, the snap assembly can be used to more conveniently remove the hammer head 4 to reduce the overall weight of the device. Use of the snap assembly: pull the pull rod 9 in the direction away from the anchor withdrawal assembly 2, the second spring 11 is compressed, and the block 12 leaves the slot 13, and the hammer head 4 can be moved in the direction away from the hammer handle 3. Remove the hammer head 4 and loosen the pull rod 9 to allow the spring to rebound. If you need to replace the hammer head 4, just align the socket at the lower end of the replaced hammer head 4 with the hammer handle 3 and insert it. When the lower end of the hammer head 4 abuts against the trapezoidal surface of the block 12, the block 12 is squeezed and bounced open, and the second spring 11 is compressed until the lower end of the hammer head 4 abuts against the support block 10. The second spring 11 rebounds, and the block 12 is immediately snapped into the slot 13 to position the replaced hammer head 4 on the hammer handle 3.
