Description

Technical Field

[0001] The utility model relates to the technical field of rock climbing, in particular to an in-situ impact device for rock plates. Background Art

[0002] Rock climbing, often called "rock ballet" or "rhythmic gymnastics on cliffs," is a derivative of mountaineering and a highly technical and adventurous sport, making it a key extreme sport. The loads exerted on the rock slab during the climber's descent can affect its quality and, in turn, its service life, creating safety hazards and potentially damaging the slab, posing a threat to personal safety. Therefore, testing the impact resistance of rock slabs is essential.

[0003] At present, when testing the impact performance of rock slabs, the test rock slabs need to be transported to the laboratory for testing. This not only requires tedious disassembly and assembly of the rock slabs, but also requires transportation and testing. The operation process is complicated and time-consuming, which affects the testing efficiency. To this end, an in-situ rock slab impact device is proposed as an improvement. Utility Model Content

[0004] The purpose of the present invention is to solve at least one of the above technical deficiencies.

[0005] To this end, one purpose of the present invention is to propose an in-situ impact device for rock slabs to solve the problems mentioned in the background technology and overcome the deficiencies in the prior art.

[0006] In order to achieve the above-mentioned purpose, an embodiment of one aspect of the present invention provides an in-situ impact device for rock slabs, comprising a hammer body, a threaded groove being provided on the top surface of the hammer body, a mounting hole being provided in the middle of the hammer body, a connecting column being threadedly connected in the threaded groove, a hanging ring being fixedly connected to the top of the connecting column, a hammer sleeve being provided at the bottom end of the hammer body, and a connecting ring being provided at the top of the hammer sleeve.

[0007] Preferably, any of the above solutions is that a thread is provided on the outer side of the bottom of the hammer body, and the thread groove is provided in the middle of the top surface of the hammer body.

[0008] Preferably, any of the above solutions is that the mounting hole is provided through the hammer body, and a transition plate is provided between the connecting column and the hanging ring.

[0009] The above technical solution is adopted: the hammer body, as the main part of the impact device, should have a certain weight so that it can generate enough impact energy during the falling process, and then hit the rock plate to test the impact performance of the rock plate. The hammer body can be made of materials with a relatively large weight, such as stainless steel and copper. A thread is provided on the outside of the bottom of the hammer body, which can be used to connect the hammer sleeve and the hammer body together with a connecting ring. The mounting hole is used to connect the external pull rod or rope to the hammer body, which is arranged in the middle of the hammer body so that the hammer body as a whole is in a balanced state as much as possible when the external pull rod or rope is pulled on the hammer body. The connecting column is threadedly connected to the hammer body through a threaded groove, so that the hanging ring can be easily disassembled and assembled. The hanging ring can facilitate the external rope to pull the hammer body from the top. A transition plate is provided between the hanging ring and the connecting column to improve the reliability of the connection between the two.

[0010] Preferably, any of the above solutions is that the hammer sleeve adopts a hemispherical structure and is made of silicon-based material.

[0011] Preferably, any of the above solutions has a threaded inner side of the connecting ring and is threadedly connected to the bottom of the hammer body.

[0012] The above technical solution is adopted: the hammer sleeve is used to directly impact the rock plate instead of the hammer body. The hammer sleeve adopts a hemispherical structure. Compared with the structure with a flat bottom surface, it can better simulate the dynamic process of the contact area of ​​the rock climber's feet changing from small to large when contacting the rock plate, which can make the force conditions during the rock plate impact test closer to the force conditions during actual use, making the test data more accurate. The hammer sleeve is connected to the bottom of the hammer body through a connecting ring thread, so that it can be easily disassembled and replaced. The hammer sleeve is made of silicon-based material, which has excellent mechanical strength and toughness, so that the hammer sleeve has high impact resistance and durability, thereby reducing the frequency of replacing the hammer sleeve and making the device as a whole more durable.

[0013] Compared with the prior art, the advantages and beneficial effects of the present invention are as follows:

[0014] 1. This in-situ impact device for rock slabs is equipped with a hammer, connecting column, hanging ring, hammer sleeve and other structures. When performing impact testing, the hanging ring is installed on the top of the hammer using the threaded groove and connecting column, and the hammer sleeve is installed on the hammer using the connecting ring. An external pull rod or pull rope is inserted through the mounting hole and connected to the hammer and the pull rod or pull rope by bolts or knots. Another pull rope is then used to tie the hanging ring from the top. The end of the pull rod or pull rope connected to the mounting hole, away from the hammer, is rotated and fixed above the surface of the rock slab to be tested. Another pull rope is used to pull the device so that the pull rod or the first pull rope is in a horizontal state and the device is in a vertical state. At this time, the pull rope connected to the hanging ring is released. Under the action of gravity and the traction of the pull rod or the first pull rope, the device performs a 1 / 4 circle motion and hits the rock slab. This process is repeated multiple times, and the test results are obtained based on the state of the rock slab. There is no need to transport the rock slab to a laboratory for testing, making the testing process faster, more convenient and more practical.

[0015] 2. This in-situ rock impact device features a threaded groove in the center of the hammer's top surface, through which the connecting post is threadedly connected to the hammer, allowing for easy assembly and disassembly of the hanging ring. The hammer sleeve is threaded onto the bottom of the hammer via the connecting ring, allowing for convenient assembly and disassembly. The sleeve is made of a silicon-based material, which has excellent mechanical strength and toughness, resulting in high impact resistance and durability. This reduces the frequency of sleeve replacement and enhances the overall durability of the device.
