Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of clip anchor unanchoring, in particular to a clip anchor unanchoring device and clip anchor unanchoring equipment. Background Art
[0002] Existing photovoltaic flexible brackets mostly use clip anchors to tension the steel strands at the ends. After tensioning, if a part of the structure is not installed properly or there are quality problems, it is necessary to use an anchor withdrawal tool to release the prestress of the anchor cable and withdraw the clip before reinstalling it. Some flexible bracket structures use double-layer clip anchors to ensure safe anchoring, so the clips of the double-layer anchor need to be withdrawn.
[0003] The existing anchor withdrawal scheme usually directly uses an anchor withdrawer to support the end of the anchor, and then uses a jack to pull the steel strand backward, so that the steel strand drives the clip out of the anchor to achieve the anchor withdrawal effect. The existing anchor withdrawer and the anchor are not positioned, and the contact surface between the anchor withdrawer and the anchor is small. Improper operation can easily damage the anchor and the clip. In addition, when a double-layer anchor is used for anchoring, the anchor withdrawer directly supports the end of the rear anchor, because the front anchor clip is supported by the rear anchor and cannot be withdrawn, which will result in the inability to withdraw the anchor. Forcibly pulling the anchor withdrawal will cause damage to the steel strand and the clip. Utility Model Content

The steel strand 3 is led out through the second through hole 42 and the first through hole 13 in sequence. When pulling the steel strand 3, the first stepped hole 11 limits the auxiliary sleeve 4, and the third stepped hole 41 limits the wedge anchor 2, achieving the effects of positioning, a large pulling force-bearing surface, and a small force on the wedge anchor 2, and will not cause damage to the wedge anchor 2.
[0036] When performing the withdrawal of a double wedge anchor 2, only need to sleeve two wedge anchors 2 into the main sleeve 1, and lead the steel strand 3 out through the first through hole 13. By pulling the steel strand 3, the double wedge anchor 2 moves synchronously, so that the wedges are loosened. Manually move the front wedge anchor 2 forward, take out the wedges in the rear wedge anchor 2, pull the wedges of the rear wedge anchor 2 to the most end position of the second stepped hole 12, press the front wedge anchor 2 against the top plate and make the rear wedge anchor 2 press against the front wedge anchor 2, and then slowly return and unload the force repeatedly until the force is completely unloaded, realizing the withdrawal operation of the double wedge anchor 2.
[0037] By providing a plurality of through grooves 14 on the main sleeve 1 that communicate with the second stepped hole 12, multiple operations can be performed when hooking out the wedges, making the operation more convenient.
[0038] Optionally, the length of the main sleeve 1 is not less than the length of three wedge anchors 2, which is convenient for accommodating the auxiliary sleeve 4 or multiple wedge anchors 2.
[0039] Optionally, the depth of the first stepped hole 11 is the same as that of the secondary sleeve 4, which improves the stability of the secondary sleeve 4 within the first stepped hole 11.

[0043] Optionally, both the main sleeve 1 and the secondary sleeve 4 are cylinders, which is convenient for assembly.
[0044] A device for retracting a wedge-type anchor device, comprising:
[0045] A retractor for the wedge-type anchor device;
[0046] A jack 5;
[0047] Wherein, the first stepped hole 11 is used for accommodating the secondary sleeve 4 or the wedge-type anchor device 2, the second stepped hole 12 is used for accommodating the wedge-type anchor device 2, the steel strand 3 is led out through the first through hole 13, the third stepped hole 41 is used for accommodating the wedge-type anchor device 2, the steel strand 3 is led out through the second through hole 42, the steel strand 3 is introduced into the wire threading hole of the jack 5, and the working end of the jack 5 is used to abut against the end of the main sleeve 1 away from the secondary sleeve 4.
[0048] Usage method:
[0049] When retracting a single wedge-type anchor device 2: put the secondary sleeve 4 on the installed wedge-type anchor device 2, then put the main sleeve 1 on the secondary sleeve 4, pass the jack 5 through the steel strand 3 and jack it against the end of the main sleeve 1 for retraction. The jack 5 pulls the steel strand 3 backward. Since the wedge-type anchor device 2 is blocked by the third stepped hole 41 in the secondary sleeve 4, the steel strand 3 can only drive the wedges in the wedge-type anchor device 2 to move backward. When the wedges are pulled out and loosen at the end of the wedge-type anchor device 2, use a tool to completely pull the wedges out of the wedge-type anchor device 2 to the outermost end position of the second stepped hole 12, and then slowly retract the jack 5 to relieve the force. If the prestress is large, repeat the above retraction operation multiple times until the force is completely relieved.
[0050] When the double wedge anchor 2 is de-anchored: directly use the main sleeve 1 to sleeve over the double wedge anchor 2, pass the jack 5 through the steel strand 3 and push it to the end of the main sleeve 1 for de-anchoring. After the jack 5 pulls the steel strand 3 backward, since there is no longer a step blocking the wedge anchor 2, the double-layer wedge anchor 2 will be pulled backward together with the steel strand 3. After pulling out a certain position, use a tool to pry the front wedge anchor 2 forward, then completely remove the wedges of the front wedge anchor 2, pull the wedges of the rear wedge anchor 2 to the outermost end position of the second step hole 12, press the front wedge anchor 2 against the top plate, and press the rear wedge anchor 2 against the front wedge anchor 2. Then slowly retract the jack 5 to relieve the force. When the prestress is large, repeat the above de-anchoring operation multiple times until the force is completely relieved (for subsequent de-anchoring, only the rear wedge anchor 2 has wedges, and just pull out the wedges of the rear wedge anchor 2).
