Description

Technical Field

[0001] The utility model relates to the technical field of coal mines, in particular to an anti-falling device for an anchor tensioner. Background Art

[0002] In underground projects such as mines and tunnels, anchor tensioners are commonly used to perform tension tests on anchors to ensure they meet safety requirements. Traditional anchor tensioners are often suspended from the tunnel mesh using simple hooks or ropes. This method carries the risk of falling off, potentially damaging the equipment and injuring on-site workers. Furthermore, the connecting chains are often crude and prone to loosening, further increasing safety risks. Previously, anchor tensioners had to be manually attached to the anchor rods, which could easily cause them to fall off and injure personnel if the rods slipped. Summary of the Invention

[0003] The purpose of this utility model is to address the risk of falling off in existing hanging methods. Once falling off, it may not only damage the equipment but also cause harm to on-site workers. In addition, the installation method of connecting the iron chain is often relatively simple and easy to loosen, further increasing the safety hazard. Therefore, an anti-falling device for anchor tensioner is proposed.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] An anchor tensioner anti-falling device includes an anchor tensioner oil cylinder, an arc-shaped sleeve is welded to the outer wall of the anchor tensioner oil cylinder, a strip-shaped through-hole is opened on one side of the arc-shaped sleeve, two symmetrically arranged side plates are fixedly connected to one side of the arc-shaped sleeve, and the two side plates are respectively located on both sides of the strip-shaped through-hole. One side of the anchor tensioner oil cylinder is fixedly connected to a connecting iron chain via a connecting assembly;

[0006] The end of the connecting iron chain away from the anchor tensioner oil cylinder is provided with a hanging assembly for hanging the device;

[0007] The same set of fixing components for fixing and connecting iron chains is arranged inside the two side plates.

[0008] In one possible design, the connecting assembly includes a connecting rod fixedly connected to one end of the connecting chain, one end of the connecting rod is fixedly connected to an extrusion plate, the interior of the strip-shaped through hole is slidably connected to a sliding plate, and the extrusion plate is used in conjunction with the sliding plate.

[0009] In one possible design, the hanging assembly includes a hanging block fixedly connected to one end of the connecting chain, a sliding groove is provided at the bottom of the hanging block, a slider is slidably connected inside the sliding groove, a tension spring is fixedly connected between one side of the slider and the inner wall of one side of the sliding groove, and an arc-shaped hook is fixedly connected to one end of the slider.

[0010] In one possible design, the fixing assembly includes a rectangular hole opened inside the side panel, a baffle is slidably passed through the inside of the rectangular hole, a groove is opened on one side of the baffle, the groove is used in conjunction with the extrusion sheet, and an arc groove is opened on one side of the baffle, the arc groove is used in conjunction with the connecting rod.

[0011] In one possible design, an insertion rod is fixedly connected to the inner wall of one side of the arc-shaped groove, one end of the insertion rod is fixedly connected to a magnet, the two magnets are attracted to each other, a socket is opened inside the connecting rod, and the insertion rod is snapped into the socket.

[0012] In a possible design, a circular hole is opened inside the baffle, a bolt passes through the circular hole, and two symmetrically arranged nuts are threaded on the outer wall of the bolt, and the nuts are in conflict with one side of the baffle.

[0013] In a possible design, a rubber pad is fixedly connected to one side of the sliding sheet, and the rubber pad contacts the outer wall of the anchor tensioner cylinder.

[0014] In this application, when in use, the arc sleeve is welded to the anchor tensioner cylinder, and the connecting iron chain is installed on one side of the arc sleeve, and the anchor tensioner cylinder is hung on the tunnel mesh through the connecting iron chain, which can effectively prevent the occurrence of falling and injuring people;

[0015] When hanging, the arc hook can be pushed upwards. At this time, the arc hook drives the slider to move horizontally inside the slide slot, and the tension spring is stretched. At this time, there is a gap between the arc hook and the hanging block, which can facilitate the hanging of the arc hook. After the hanging is completed, the slider is reset under the tension of the tension spring, which can make the arc hook hook the tunnel mesh tightly and improve stability.

[0016] When installing the connecting chain, you can first press the extrusion plate against one side of the sliding plate. At this time, press the sliding plate against the outer wall of the anchor tensioner cylinder. The setting of the rubber pad can increase the friction and ensure stability. Then move the two baffles close to each other. At this time, the arc groove is engaged with the connecting rod, and the plug rod is inserted into the inside of the socket. The two magnets attract each other to ensure the connection stability of the device. Then insert the two bolts into the corresponding round holes and tighten the two nuts. At this time, the connection stability of the baffle can be guaranteed, the baffle can be prevented from loosening, and the stability of the device can be improved again.

[0017] Beneficial Effects: Improved safety: By welding the curved sleeve to the anchor tensioner cylinder and using a connecting chain to hang it on the roadway mesh, it effectively prevents the possibility of falling and injuring people. This stable and reliable structure ensures the stability of the anchor tensioner during use, greatly reducing safety risks.

[0018] Easy to hang: The hanging mechanism of this application is cleverly designed. Through the coordination of the arc hook and the slider, and the tension of the tension spring, the hanging process is more convenient and the stability after hanging is guaranteed. This design not only improves work efficiency, but also further enhances the safety of the equipment.

[0019] Stable connection: This application utilizes multiple connection mechanisms, including extrusion plates, sliding plates, baffles, connecting rods, inserts, and magnets, to secure the chain to the anchor tensioner cylinder. Furthermore, the use of bolts and nuts further enhances the stability of the connection, preventing loosening.

[0020] Strong adaptability: The device of this application has a simple structure and is easy to operate. It is applicable to various types and specifications of anchor tensioners and has strong versatility and adaptability. At the same time, its ruggedness and durability also enable the device to operate stably and long-term in harsh underground engineering environments. BRIEF DESCRIPTION OF THE DRAWINGS
