Description

Technical Field

[0001] The present application relates to the field of anchor rod technology, and in particular to an integrated anchor rod fastening and detection device. Background Art

[0002] Anchor rods are the most basic component of tunnel support in modern coal mines. They reinforce the surrounding rock of the tunnel so that the surrounding rock can support itself. Anchor rods are not only used in mines, but also in engineering technology to reinforce the main body of slopes, tunnels, and dams. As a tensile member that penetrates deep into the stratum, one end of the anchor rod is connected to the engineering structure, and the other end penetrates deep into the stratum. The entire anchor rod is divided into a free section and an anchoring section. The free section refers to the area where the tension at the anchor rod head is transmitted to the anchor body. Its function is to apply prestress to the anchor rod.

[0003] The patent document with publication number CN216422430U in the prior art provides a T-type anchor rod fastening device. The device uses the T-type anchor rod fastening device and the T-type anchor rod pre-tightening device to utilize the lever principle to twist the anchor rod limit nut. When in use, external force is applied to the handle along the direction of thread rotation to twist the anchor rod limit nut. The operation is simple, safe and reliable, avoiding the previous phenomenon of manually standing on the operating table and tightening the limit nut with a large wrench, ensuring the safety of workers during construction, and ensuring that the anchor rod pre-tightening force meets the requirements.

[0029] Reference Figure 1 and Figure 2 , the embodiment of the present application discloses an integrated anchor bolt fastening and detection device. Shell 1, a fastening mechanism 2 and a torque limiter 3 are mounted on the shell 1;

[0030] The fastening mechanism 2 includes a transmission frame 4 connected and fixed to the torque limiter 3, and a plurality of transmission rods 5 are slidably connected inside the transmission frame 4. The plurality of transmission rods 5 are internally snap-fitted with a limiting nut 6, and one end of the limiting nut 6 is rotatably connected to an abutment frame 7, and the limiting nut 6 is threadedly connected to the screw on the anchor rod.

[0031] The tightening mechanism 2 cooperates with the design of the torque limiter 3, and can stop after reaching the specified torque according to the setting of the torque limiter 3 when tightening the anchor rod. In this way, the anchor rod can be guaranteed to be qualified after tightening, and the fixing of the anchor rod is relatively easy and fast, with high work efficiency.

[0032] Reference Figure 2 A fastening motor 8 is connected and fixed to the torque limiter 3 , and the fastening motor 8 is installed in the housing 1 .

[0033] The output shaft of the tightening motor 8 drives the transmission frame 4 through the connected torque limiter 3, thereby driving the transmission rod 5 inside it to rotate, and the limit nut 6 at the end of the transmission rod 5 will be rotated to connect with the screw part of the anchor rod. As the abutment frame 7 abuts against the wall, etc., the inserted part of the anchor rod will expand and be fastened to the inside of the wall, etc. When the torque limiter 3 works, the anchor rod is fixed.

[0034] Reference Figure 2 A compression spring 9 is connected and fixed inside the transmission frame 4 , and the other end of the compression spring 9 is connected and fixed to the transmission rod 5 .

[0035] The design of the transmission rod 5 being in sliding connection with the transmission frame 4 in cooperation with the compression spring 9 can make the device suitable for installation of different anchor rods and has a wide application range.

[0036] An adjusting frame 10 is rotatably connected to the transmission frame 4, an adjusting rod 11 is slidably connected inside the adjusting frame 10, a plurality of matching grooves 12 are opened on the adjusting frame 10, the adjusting rod 11 is fixedly connected to the transmission rod 5, the adjusting rod 11 is slidably connected to the matching groove 12, and the adjusting frame 10 is rotatably connected to the torque limiter 3.

[0037] The adjusting frame 10 can be rotated to drive the adjusting rod 11 to slide inside it, and the other end of the adjusting rod 11 is limited by the matching groove 12, so the other end of the adjusting rod 11 can drive the transmission rod 5 to move outward. At this time, the compression spring 9 is compressed, so that multiple transmission rods 5 can be driven to expand at the same time, which is convenient for connecting different limit nuts 6 and abutment frames 7, and is more convenient to use.

[0038] Reference Figure 3 A plurality of limit springs 13 are connected and fixed to the adjustment frame 10 , and the other end of the limit spring 13 is connected and fixed to a limit block 14 .

[0039] After the adjustment frame 10 is rotated, the limit spring 13 drives the limit block 14 to engage with the limit groove 15. In this way, the adjustment frame 10 can remain in a fixed state after rotation without external force, which further facilitates the installation of the limit nut 6 and the abutment frame 7.

[0040] The implementation principle of the anchor bolt fastening and detection integrated device of the embodiment of the present application is as follows: after the anchor bolt is inserted into the wall, the limit nut 6 is threadedly connected with the screw on the anchor bolt, and then the output shaft of the fastening motor 8 drives the transmission frame 4 through the connected torque limiter 3, thereby driving the transmission rod 5 inside it to rotate, and the limit nut 6 at the end of the transmission rod 5 will be rotated to connect with the screw part of the anchor bolt, and as the abutment frame 7 abuts against the wall, the inserted part of the anchor bolt will expand and be fastened to the inside of the wall, and when the torque limiter 3 works, the anchor bolt is fixed;

[0041] When replacing the limit nut 6, rotating the adjustment frame 10 drives the adjustment rod 11 to slide inside it, and the other end of the adjustment rod 11 is limited by the matching groove 12, so the other end of the adjustment rod 11 can drive the transmission rod 5 to move outward. At this time, the compression spring 9 is compressed, so that multiple transmission rods 5 can be driven to expand at the same time. At this time, the limit spring 13 drives the limit block 14 to engage with the limit groove 15. In this way, in the absence of external force, the adjustment frame 10 can remain in a fixed state after rotation. After replacing the limit nut 6, the adjustment frame 10 can be rotated in the opposite direction.
