[0027] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0028] Example: Figure 1 As shown, the connection device for pulling the pipe seam anchor in this embodiment includes an anchor connector 1 and a connection seat 2. The anchor connector 1 is detachably mounted on the end of the pipe seam anchor. The connection seat 2 is close to the end of the pipe seam anchor and is detachably connected to the anchor connector 1. The connection seat 2 is provided with an assembly part 23 connected to the pulling device.

[0029] The usage process is as follows:

[0030] First, assemble the anchor rod connector 1 at the end of the pipe seam anchor rod, then assemble the connection seat 2 and the anchor rod connector 1, and then connect the assembly part 23 to the pulling device, and operate the pulling device to perform a pulling test on the assembly part 23, the connection seat 2 and the anchor rod connector 1. Since the pipe seam anchor rod connector 1 is firmly installed at the end of the pipe seam anchor rod, the pulling will act on the pipe seam anchor rod, and the pulling test of the pipe seam anchor rod is realized. The overall structural design is simple and reasonable, the assembly is quick and convenient, and the pipe seam anchor rod and the pulling device can be stably connected, ensuring that the pipe seam anchor rod can be effectively pulled out.

[0031] As a preferred embodiment, the anchor rod connector 1 is a high-pressure pipe clamp, which includes two semicircular ring-shaped hoops 11, and the two ends of the two hoops 11 are respectively provided with connecting parts 12. The two hoops 11 are embraced on the end side walls of the above-mentioned pipe seam type anchor rod, and the connecting parts 12 at both ends of the two are close to each other one by one, and are connected by bolts passing through the corresponding two connecting parts 12.

[0032] In the above implementation scheme, the anchor rod connector 1 adopts a conventional high-pressure pipe clamp, the size of which is selected to be compatible with the pipe seam type anchor rod, and is fixed on the end side wall of the pipe seam type anchor rod, and then the anchor rod connector 1 is assembled with the connecting seat 2. Among them, the anchor rod connector 1 has a simple structure and is relatively quick and convenient to operate.

[0033] As a preferred embodiment, the connecting seat 2 includes a plate-shaped seat body 21 , one end of which is vertically provided with a connecting block 22 corresponding to the connecting parts 12 at both ends, and the bolt passes through the corresponding two connecting parts 12 and the connecting block 22 .

[0034] In the above-mentioned implementation scheme, one end of the seat body 21 of the connecting seat 2 is provided with a connecting block 22 adapted to the connecting parts 12 at both ends of the high-pressure pipe clamp. When the high-pressure pipe clamp is assembled at the end of the pipe seam type anchor rod, the connecting block 22 is placed against the connecting part 12, and bolts are used to penetrate the holes on the connecting part 12 and the connecting block 22, and then nuts are installed on the rods of the bolts to lock them. This structural design can make the connecting seat 2 and the high-pressure pipe clamp firmly connected while operating the high-pressure pipe clamp to clamp the pipe seam type anchor rod. The bolts of the high-pressure pipe clamp are used to connect the two, and the structural design is relatively ingenious.

[0035] As a preferred embodiment, the pulling device is a mortar anchor puller, and the assembly part 23 is a pulling rod that passes through the seat body 21 along the long axis direction of the tube seam anchor. The end of the pulling rod away from the tube seam anchor is provided with a threaded section that is threadedly connected to the mortar anchor puller.

[0036] In the above embodiment, the pulling device adopts a mortar anchor puller of a model adapted from the prior art. The oil cylinder of the mortar anchor puller is provided with a threaded hole. Therefore, a threaded section is provided at the end of the pulling rod away from the above-mentioned pipe seam anchor and is threadedly connected to the oil cylinder. The assembly is relatively simple, convenient and quick.

[0037] As a preferred embodiment, a through hole is penetrated through the seat body 21 , one end of the pulling rod passes through the through hole and is connected to the mortar anchor pulling instrument, and the other end is provided with a limiting portion 31 .

[0038] In the above embodiment, due to the design of the limiting portion 31, after the pulling pin passes through the through hole of the seat body 21, it will not completely pass through and will be limited by the limiting portion 31. Therefore, after the pulling pin is connected to the mortar anchor pulling instrument, when pulling in a direction away from the pipe seam anchor, the pulling force can be applied to the pipe seam anchor. The structural design is simple and is conducive to the subsequent effective pulling test operation.

[0039] In this embodiment, Figure 2 As shown, the above-mentioned assembly part 23 can also use a countersunk bolt. A bolt hole adapted to the above-mentioned countersunk bolt is penetrated through the above-mentioned seat body 21. The screw rod of the countersunk bolt can be threadedly connected with the bolt hole adapted to the cylinder of the mortar anchor puller, which is convenient for disassembly and assembly.

[0040] In this embodiment, the seat body 21 is a steel member, and the connecting block 22 is welded and fixed to the seat body 21. The structural strength of the two is relatively high and can meet the drawing requirements.

[0041] As a preferred embodiment, Figure 3 and 4 As shown, the connecting block 22 is a U-shaped block, whose closed end is welded and fixed to the seat body 21 , and whose two ends are respectively arranged at the two ends of the corresponding two connecting parts 12 , and the bolts penetrate the two corresponding connecting parts 12 and the two ends of the connecting block 22 .

[0042] In the above implementation scheme, the connecting block 22 adopts a U-shaped block. During assembly, the two ends of the connecting block 22 are respectively "stuck" on the two sides of the two corresponding connecting parts 12, and then the high-pressure pipe clamp is penetrated by bolts and locked by nuts to achieve the clamping of the high-pressure pipe clamp on the pipe seam anchor rod and the assembly of the connecting seat 2.

[0043] In this embodiment, Figure 5 As shown, the above-mentioned anchor rod connector 1 is provided with two groups. When designing, the length of the connecting block 22 is lengthened and extends to the side ends of the connecting parts 12 of the two groups of anchor rod connectors 1 along the long axis direction of the anchor rod, respectively, and the corresponding two connecting parts 12 are respectively fixed by bolts penetrating through them and the connecting block 22, and the two groups of anchor rod connectors 1 are fixed on the anchor rod very firmly to avoid falling off when pulling.

[0044] In this embodiment, Figure 6 As shown, the end of the above-mentioned pipe seam anchor is welded with a limiting ring 3. The design of the limiting ring 3 can limit the anchor connector 1 from being separated from the end of the pipe seam anchor, ensuring smooth pulling.
