Description

Technical Field

[0001] The present invention belongs to the technical field of roadway operations, and specifically relates to a rock knocking and roof sounding device for roadways. Background Art

[0002] Rock knocking and roof sounding refers to a safety operation before underground production operations. Specifically, it is a method of using tools to strike the roadway, the roof and sidewalls of the working face, and detecting loose rocks and delaminations through the sounds emitted. This method can help workers determine whether the surrounding rock mass is loose, fractured or delaminated, so as to prevent potential safety hazards. When problems such as loosening occur, it is necessary to first mark the hidden danger points of the roadway and then carry out support to avoid safety problems such as roof falls and cause huge losses. Currently, during the operation of rock knocking and roof sounding, generally, workers with certain work experience use tools such as crowbars and steel drills to strike the roof and sidewalls, and detect the positions with potential hazards based on the sounds emitted.

[0003] The patent document with the patent number "CN220650563U" discloses a rock knocking and roof sounding tool for use in coal mines. It includes a metal knocking rod, and further includes: a clamping component provided at the bottom end of the metal knocking rod for clamping and positioning the metal knocking rod; a lockable telescopic rod provided below the clamping component for adjusting the use length of the metal knocking rod; a holding component provided at the bottom end of the lockable telescopic rod for facilitating the user to lift the metal knocking rod upward to achieve rock knocking and roof sounding of the coal mine shaft; and a gripping component. This utility model can facilitate workers to accurately and repeatedly strike the shaft wall of the coal mine when moving the metal knocking rod upward, which can not only improve the efficiency of rock knocking and roof sounding of the shaft wall, but also improve the safety of workers when using the tool.

[0004] Although the above technical solution solves the problem of being unable to repeatedly strike the shaft wall, when using this tool, workers need to lift it to strike the top of the roadway multiple times, and need to repeatedly counteract gravity through their own muscle contractions, which easily causes muscle soreness and may lead to non-standard operations during subsequent rock knocking and roof sounding, resulting in problems such as missed inspections or misinspections.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. The present invention adopts the technical means of cooperating the rod body, the rotating rod, the knocking rod and the spring. When the staff uses it, there is no need to raise the arm high. Just by pressing down the rod body, the knocking rod can be driven to rise under the action of the lever principle, so as to realize the operation of knocking on the roof and sides of the roadway. At the same time, when resetting, under the action of the pulling force of the spring and the gravity of the knocking rod, the reset operation can be easily realized, reducing the workload of the workers and reducing the occurrence of muscle soreness.

[0019] 2. By setting the observation mirror, the fixed pulley, the pulling rope and the cleaning plate in the present invention, the worker can look down at the observation mirror to determine the position of knocking on the roof and sides of the roadway. The worker does not need to look up for a long time, which may cause shoulder and neck soreness. At the same time, since there will be dust on the roof when knocking on the roof and sides of the roadway, the dust will fall on the observation mirror. The surface of the observation mirror can be cleaned by driving the cleaning plate to rotate by the rotating rod.

[0020] 3. By setting the structure of cooperating the knocking ball and the collision plate in the present invention, when knocking on the roof and sides of the roadway, due to the relatively large noise in the roadway, there is a certain interference with the sound at the knocking place, and it is not easy to judge the specific situation of the knocking position. After the knocking ball knocks, the knocking plate will move different distances under the action of different sizes of reaction forces. A collision plate is set at a certain distance. When the reaction force is small, the knocking plate cannot touch the collision plate. Whether the collision plate makes a sound can be used to judge the situation of the knocking position, which can improve the accuracy of judgment to a certain extent.

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] As Figures 1 to 9 shown, the embodiment of the present invention provides a device for knocking on the roof and sides of a roadway, including an elliptical sleeve 1 for wearing on the upper body, including:

[0033] A knocking mechanism is arranged on the elliptical sleeve 1. The knocking mechanism includes a mounting shell 5. A rotating rod 7 is rotatably installed on the inner wall of the mounting shell 5. A rotating plate 8 is fixedly installed on the rotating rod 7. A knocking rod 9 is fixedly installed on the rotating plate 8. A rod body 12 is fixedly installed on the rotating plate 8.

[0034] The working principle and beneficial effects of the above technical solution are as follows: When knocking on the roof and sides is required, the staff can press down the rod body 12. When the rod body 12 moves downward, it will drive the rotating plate 8 to rotate around the rotating rod 7. Under the action of the lever principle, the rotating plate 8 drives the knocking rod 9 to move upward, so as to knock on the top of the roadway. According to the knocking, the operation of knocking on the roof and sides can be realized. When the knocking rod 9 needs to be reset, release the hand, and it can be reset.

[0035] In one embodiment: A first mounting block is fixedly installed on the rotating plate 8, a second mounting block is fixedly installed on the inner top plate of the mounting shell 5, a spring 10 is fixedly installed on the first mounting block, and the other end of the spring 10 is fixedly connected to the second mounting block.

[0036] The working principle and beneficial effects of the above technical solution are that when the knocking rod 9 needs to be reset, the spring 10 provides a pulling force, and the reset effect is better.

[0037] In one embodiment: An observation mirror 6 is fixedly installed on the top plate of the mounting shell 5, and a cleaning mechanism for cleaning the observation mirror 6 is provided on the observation mirror 6.

[0038] The working principle and beneficial effects of the above technical solution are: The observation mirror 6 can be cleaned by the cleaning mechanism.

[0039] In one embodiment: The cleaning mechanism includes an arc-shaped mounting groove opened on the inner side of the lens frame, a rotating shaft 19 is rotatably installed in the arc-shaped mounting groove, a cleaning plate 18 is fixedly installed on the rotating shaft 19, a scraping strip 20 is arranged on the side of the cleaning plate 18 close to the lens, a torsion spring 21 is sleeved on the rotating shaft 19, one end of the torsion spring 21 is fixedly connected to the rotating shaft 19, and the other end thereof is fixedly connected to the inner wall of the lens frame. A pulling rope 13 is fixedly installed on the rod body 12, and the other end of the pulling rope 13 is fixedly connected to the cleaning plate 18. A circular hole is opened on the top of the mounting shell 5, and a fixed pulley 14 for guiding is rotatably installed on the top plate of the mounting shell 5 beside the circular hole. The middle section of the pulling rope 13 is in rolling cooperation with the fixed pulley 14.

[0040] The working principle and beneficial effects of the above technical solution are: When the rod body 12 moves, it will drive the pulling rope 13 to move. The movement of the pulling rope 13 will pull the cleaning plate 18 to move, and the scraping strip 20 on the cleaning plate 18 will clean the lens. The torsion spring 21 can reset the cleaning plate 18 after the external force of the pulling rope 13 is removed.

[0041] In one embodiment: An arc-shaped groove is opened on the side wall of the mounting shell 5, and a rubber protective pad 15 is fixedly installed at the end of the arc-shaped groove.

[0042] The working principle and beneficial effects of the above technical solution are: The rubber protective pad 15 can protect the rod body 12 and reduce the vibration when the rod body 12 is reset.

[0043] In one embodiment: A knocking ball 24 is fixedly installed at the end of the knocking rod 9 away from the mounting shell 5. The knocking ball 24 is of a hollow structure, a collision plate 28 is fixedly installed on the inner wall of the knocking ball 24, a receiving block 25 is slidably installed on the side wall of the knocking ball 24, a knocking plate is fixedly installed at the lower end of the receiving block 25, a sliding groove is opened on the knocking plate, a reset spring 26 is arranged on the side wall of the sliding groove, one end of the reset spring 26 is fixedly connected to the inner wall of the sliding groove, and a knocking head 27 is fixedly installed at the other end of the reset spring 26.

[0044] The working principle and beneficial effects of the above technical solution are as follows: When knocking, since the magnitudes of the reaction forces are different when knocking on the solid part and the hollow part, the reaction force at the solid part is larger and the reaction force at the hollow part is smaller. When knocking on the hollow part, the reaction force received by the receiving block 25 is small, and the moving distance will be shorter. At this time, the knocking block moves a shorter distance and cannot knock on the collision plate 28 to make it emit a sound. When knocking on the solid part, the reaction force received by the receiving block 25 is greater, and the moving distance will be longer, which will drive the knocking block to move a longer distance. Moreover, since the collision plate 28 is a metal plate, the knocking plate will knock on the collision plate 28 to make it emit a sound, so it is possible to judge whether the knocking part is hollow or solid by whether a sound is emitted.

[0045] In one embodiment: A shoulder strap 2 is fixedly installed on the elliptical sleeve 1. A hook-and-loop fastener male surface 22 is fixedly installed at one end of the shoulder strap 2 away from the fixed end. A hook-and-loop fastener female surface 23 is provided at a position on the elliptical sleeve 1 corresponding to the hook-and-loop fastener male surface 22 on the shoulder strap 2.

[0046] The working principle and beneficial effects of the above technical solution are as follows: The position of the hook-and-loop fastener male surface 22 on the shoulder strap 2 on the hook-and-loop fastener female surface 23 on the elliptical sleeve 1 can be adjusted to facilitate workers of different body sizes to use the device.

[0047] In one embodiment: A rotating disk 4 is fixedly installed on the mounting shell 5. A fixing block 3 is fixedly installed on one side of the rotating disk 4 away from the mounting shell 5. The fixing block 3 is fixedly connected to the elliptical sleeve 1. A fixing mechanism is provided on the rotating disk 4.

[0048] The working principle and beneficial effects of the above technical solution are as follows: Since knocking on the roof and sides of the roadway not only requires knocking on the top of the roadway, when knocking in other directions is needed, the worker can rotate the rotating disk 4 by hand, so as to drive the device on the rotating disk 4 to rotate, and then knocking on the roof and sides at the required position can be carried out.

[0049] In one embodiment: The fixing mechanism includes an internal gear ring 16. A locking tooth 17 is slidably installed on the fixing block 3 below the internal gear ring 16.

[0050] The working principle and beneficial effects of the above technical solution are as follows: The rotating disk 4 can be fixed through the cooperation of the locking tooth 17 and the internal gear ring 16 to prevent the rotating disk 4 from rotating during the work of knocking on the roof and sides of the roadway.

[0051] In one embodiment: A lighting mechanism is fixedly installed on the outer wall of the mounting shell 5. The lighting mechanism includes a mounting seat, and a lighting miner's lamp 11 is rotatably installed on the mounting seat.

[0052] The working principle and beneficial effects of the above technical solution are as follows: Since when the device is in use, the worker needs to lower his head to operate, and the miner's lamp on his head cannot illuminate the top of the roadway, a rotatable illuminating miner's lamp 11 is provided on the mounting shell 5, so as to illuminate the place that needs to be illuminated.

[0053] Working principle and usage process: When a worker needs to check the roof and sides of the roadway in the roadway, the device in this embodiment can be used. The worker can adjust the position of the hook surface 22 of the magic tape on the strap 2 on the loop surface 23 of the magic tape on the elliptical sleeve 1 to put on the device, and then move forward. When working, the worker can press down the rod body 12. When the rod body 12 moves downward, it will drive the rotating plate 8 to rotate. Under the action of the lever principle, the knocking rod 9 can be driven to move upward, so as to knock on the top of the roadway and realize the operation of checking the roof and sides. When the knocking rod 9 needs to be reset, release the hand, and it can be reset under its own gravity and the pulling force of the spring 10. At the same time, when the rod body 12 moves, it will drive the pull rope 13 to move. After being guided by the circular hole and the fixed pulley 14, the pull rope 13 will drive the cleaning plate 18 to move, so as to clean the surface of the observation mirror 6. After the knocking rod 9 is reset, the pull rope 13 is slack, and under the action of the torsion spring 21, it will drive the cleaning plate 18 to reset. When the knocking rod 9 knocks, it will drive the knocking ball 24 to move and knock. When knocking, since the reaction forces are different when knocking on the solid part and the hollow part, the reaction force of the solid part is larger and the reaction force of the hollow part is smaller. When knocking on the hollow part, the reaction force received by the bearing block 25 is small, and the moving distance will be shorter. At this time, the knocking block moves a shorter distance and cannot knock on the collision plate 28 to make it emit a sound. When knocking on the solid part, the reaction force received by the bearing block 25 is greater, and the moving distance will be longer, which will drive the knocking block to move a longer distance, and the knocking plate will knock on the collision plate 28 to make it emit a sound. Thus, it can be judged whether the knocking place is hollow or solid by whether a sound is emitted. Since checking the roof and sides not only requires knocking on the top of the roadway, when knocking on other directions is needed, the worker can rotate the rotating disc 4 by hand, so as to drive the device on the rotating disc 4 to rotate, and then the roof and sides of the required position can be checked. And since when the device is in use, the worker needs to lower his head to operate, and the miner's lamp on his head cannot illuminate the top of the roadway, a rotatable illuminating miner's lamp 11 is provided on the mounting shell 5, so as to illuminate the place that needs to be illuminated.
