DETAILED DESCRIPTION

[0021] 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.

[0022] like Figures 1 to 5 As shown:

[0023] Embodiment 1: The utility model provides a clip removal auxiliary device for anchor cable pulling test, comprising: an anchor cable mechanism 1, including a tray 11, an anchor cable assembly 12 installed on the tray 11; an anchor withdrawal mechanism 2, including a sleeve assembly 21 located below the tray 11, and an anchor withdrawal assembly 22 slidably embedded in the sleeve assembly 21.

[0024] Specifically, the anchor cable assembly 12 includes an anchor cable steel strand 121 , one end of which passes through the tray 11 , a clip 122 is embedded on the outside of the anchor cable steel strand 121 , and an anchor cup 123 is slidably connected to the outside of the clip 122 .

[0025] Specifically, the sleeve assembly 21 includes a sleeve body 211 that is attached to the bottom of the tray 11. The sleeve body 211 is sleeved on the outside of the anchor cable strand 121. An annular groove is provided on the sleeve body 211, and a spring 212 is slidably embedded in the annular groove. A plurality of limiting grooves 213 are provided on the sleeve body 211 in a circular array. The limiting grooves 213 are connected to the annular groove. A threaded hole 214 is symmetrically provided on one side of the sleeve body 211 close to the bottom.

[0026] Specifically, a bolt 215 is threadedly connected in the threaded hole 214 , and the bolt 215 can fix the anchor withdrawal assembly 22 to the sleeve body 211 .

[0027] As can be seen from the above, when the clip 122 needs to be removed, the bolt 215 is rotated so that the bolt 215 releases the limit on the anchor withdrawal assembly 22. At this time, the anchor cup 123 can be pushed upward, and the anchor cup 123 squeezes the anchor withdrawal assembly 22 upward so that the anchor withdrawal assembly 22 slides on the sleeve body 211. When the anchor cup 123 moves upward, the limit on the clip 122 can be released. At this time, the clip 122 can be easily taken out, which is convenient for the staff to operate.

[0028] Embodiment 2: This embodiment is basically the same as the previous embodiment, with the difference that the anchor withdrawal assembly 22 includes an anchor withdrawal ring 221 that is slidably embedded in the annular groove, a plurality of limit blocks 222 are fixedly connected to the anchor withdrawal ring 221 in a circular array, the limit blocks 222 are slidably embedded in the limit groove 213, and a plurality of extrusion blocks 223 are fixedly connected to the bottom of the anchor withdrawal ring 221 in a circular array.

[0029] Specifically, the top of the anchor cup 123 abuts against a plurality of extrusion blocks 223 .

[0030] As can be seen from the above, when the anchor cup 123 is pushed upward, the anchor cup 123 pushes the extrusion block 223, and the extrusion block 223 drives the anchor withdrawal ring 221 to move upward. Through the cooperation of the limit block 222 and the limit groove 213, the anchor withdrawal ring 221 can move upward stably. While the anchor withdrawal ring 221 moves upward, it squeezes the spring 212, so that the spring 212 is in a compressed state. After the clip 122 is taken out, the squeezing of the anchor withdrawal assembly 22 is released. At this time, the spring 212 restores its deformation and pushes the anchor withdrawal assembly 22 to its original state, and the anchor withdrawal assembly 22 is fixed to the sleeve body 211 by the bolt 215 so that it can be used next time.

[0031] The embodiments of the present invention are provided for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
