Description

Technical Field

[0001] This utility model belongs to the field of mining equipment technology, specifically, it relates to a suspended mounting frame and an intrinsically safe camera for mining. Background Technology

[0002] In mining operations, intrinsically safe cameras play a crucial role in environmental monitoring. However, the harsh environment inside the mine presents many challenges to the stable operation and clear imaging of these cameras.

[0003] Mines experience frequent vibrations and impacts, such as blasting vibrations from mining operations, collisions with transport equipment, and rockfalls. However, existing mining camera mounting frames are mostly rigid structures, which cannot effectively buffer these vibrations and impacts. This makes the precision electronic components inside the camera, such as the focusing components of the lens and the image sensor, extremely susceptible to damage due to vibrations and impacts, thereby shortening the camera's lifespan and increasing maintenance costs and the risk of equipment failure. In view of this, this utility model is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a suspension mounting frame and an intrinsically safe camera for mining that can overcome or at least partially solve the above problems.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0006] A suspension mounting bracket includes a reinforcing rod and further includes: a buffer cavity formed within the reinforcing rod, wherein a slider is slidably connected within the buffer cavity, and a damping sleeve is fixedly connected to the slider, the damping sleeve fitting against the inner wall of the buffer cavity; a spring one disposed within the buffer cavity, wherein one end of the spring one is fixedly connected to the slider, and the other end is fixedly connected to the inner wall of the lower end of the buffer cavity; a fixing rod fixedly connected to the slider; a connecting ring fixedly connected to the reinforcing rod, wherein a rotating shaft is symmetrically rotatably connected to the connecting ring, both ends of the rotating shaft are fixedly connected to limit blocks, a connecting rod one is fixedly connected to the rotating shaft, a torsion spring is sleeved on the rotating shaft, one end of the torsion spring is fixedly connected to the limit block, and the other end is fixedly connected to the side wall of the connecting ring; and a connecting rod two, one end of which is rotatably connected to the end of the connecting rod one away from the connecting ring, and the other end of which is fixedly connected to the end of the fixing rod penetrating the lower end of the buffer cavity.

[0007] Preferably, it further includes a mounting base, which is connected to the reinforcing rod, and the mounting base has multiple mounting holes equidistantly spaced around its circumference.

[0008] In order to adjust the length of the suspension mounting bracket according to the needs, the upper end of the reinforcing rod is provided with a plug groove, and a telescopic rod is slidably connected in the plug groove. The reinforcing rod is provided with multiple adjustment holes that communicate with the plug groove at equal intervals. The telescopic rod is provided with a locking component that cooperates with the adjustment holes. The mounting base is fixedly connected to the end of the telescopic rod away from the plug groove.

[0009] In order to lock and limit the telescopic rod, the locking component further includes a sliding groove formed on the telescopic rod and a locking block slidably connected in the sliding groove. A second spring is provided in the sliding groove, one end of which is fixedly connected to the locking block and the other end is fixedly connected to the inner wall of the sliding groove.

[0010] The intrinsically safe camera for mining also includes a camera body, which is detachably connected to one end of the fixed rod that passes through the lower end of the buffer cavity.

[0011] To facilitate the assembly and disassembly of the camera body, multiple fixing bolts are further included, and the camera body is detachably connected to the fixing rod through multiple fixing bolts.

[0012] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0013] This invention utilizes the elastic deformation of torsion springs and springs to buffer vibrations in the horizontal and vertical directions, respectively. At the same time, the damping sleeve increases the damping when the slider slides, consuming some vibration energy. This effectively reduces the impact of external vibrations and impacts on the camera body, protects internal precision components, extends service life, and ensures the stability and clarity of the captured images.

[0014] The design of the telescopic rod and reinforcing rod, along with the locking mechanism, allows for flexible adjustment of the mounting height according to the actual environment and needs. This ensures the camera is positioned at the optimal shooting location, meeting different monitoring angle requirements and improving applicability and monitoring effectiveness. Meanwhile, the combination of spring 2 and locking block guarantees the stable and fixed position of the telescopic rod after adjustment, preventing slippage due to vibration.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0022] Example 1:

[0023] Reference Figure 1 , Figure 2 , Figure 3 The suspended mounting frame and intrinsically safe mining camera include a reinforcing rod 1, and further include: a buffer cavity 2 formed within the reinforcing rod 1, wherein a slider 201 is slidably connected within the buffer cavity 2, and a damping sleeve 202 is fixedly connected to the slider 201, the damping sleeve 202 fitting against the inner wall of the buffer cavity 2; a spring 204 disposed within the buffer cavity 2, wherein one end of the spring 204 is fixedly connected to the slider 201, and the other end is fixedly connected to the inner wall of the lower end of the buffer cavity 2; a fixing rod 203 fixedly connected to the slider 201; and a connecting ring 4. The connecting ring 4 is symmetrically connected to the reinforcing rod 1. A rotating shaft 401 is rotatably connected to the connecting ring 4. Limiting blocks 402 are fixedly connected to both ends of the rotating shaft 401. A connecting rod 403 is fixedly connected to the rotating shaft 401. A torsion spring 404 is sleeved on the rotating shaft 401. One end of the torsion spring 404 is fixedly connected to the limiting block 402, and the other end is fixedly connected to the side wall of the connecting ring 4. A second connecting rod 405 is rotatably connected to the end of the first connecting rod 403 away from the connecting ring 4, and the other end is fixedly connected to the end of the fixed rod 203 that passes through the lower end of the buffer cavity 2.

[0024] It also includes a camera body 5, which is detachably connected to one end of the fixing rod 203 that passes through the lower end of the buffer cavity 2.

[0025] When the suspended mounting bracket is subjected to external vibration or impact, the camera body 5 drives the fixed rod 203 to move, which in turn drives the connecting rod 403 and the rotating shaft 401 to rotate through the connecting rod 2 405, causing the torsion spring 404 to undergo torsional deformation. At the same time, the fixed rod 203 drives the slider 201 to slide in the buffer cavity 2, compressing or stretching the spring 204. Then, when the vibration or impact disappears, the torsion spring 404 and the spring 204 restore their deformation, causing the mounting bracket and the camera body 5 to return to their initial positions.

[0026] In summary, by utilizing the elastic deformation of torsion spring 404 and spring 204 to absorb and buffer external vibration and impact energy, torsion spring 404 twists when connecting rod 403 rotates, storing elastic potential energy and buffering vibration in the horizontal direction. Spring 204 is compressed or stretched when slider 201 slides, storing and releasing energy and playing a buffering role in the vertical direction. At the same time, damping sleeve 202 fits against the inner wall of buffer cavity 2, increasing the damping when slider 201 slides, which can consume some vibration energy and make the buffering effect more stable. This design can effectively reduce the impact of external vibration and impact on camera body 5, protect the precision components inside camera body 5, extend the service life of camera body 5, and ensure the stability and clarity of the images captured by camera body 5.

[0027] Example 2:

[0028] Reference Figure 1 The suspended mounting frame and the intrinsically safe camera for mining are basically the same as in Embodiment 1. Furthermore, it also includes a mounting base 102, which is connected to the reinforcing rod 1. Multiple mounting holes 103 are equidistantly opened on the circumference of the mounting base 102.

[0029] The mounting base 102 and mounting holes 103 provide a connection interface between the suspended mounting frame and the outside world. The mounting holes 103, which are equidistant from each other on the circumference, can be adapted to connectors of different specifications and installation methods, making it convenient for the mounting frame to be firmly connected to different mounting surfaces. This improves the versatility and ease of installation of the mounting frame and ensures that the mounting frame can be stably fixed in complex environments such as mines.

[0030] Example 3:

[0031] Reference Figure 1 , Figure 2 , Figure 4The suspension mounting frame and the intrinsically safe camera for mining are basically the same as in Embodiment 1. Furthermore, the upper end of the reinforcing rod 1 is provided with a plug groove, and a telescopic rod 101 is slidably connected in the plug groove. Multiple adjustment holes 303 that communicate with the plug groove are provided at equal intervals on the reinforcing rod 1. The telescopic rod 101 is provided with a locking component that cooperates with the adjustment holes 303. The mounting base 102 is fixedly connected to the end of the telescopic rod 101 away from the plug groove.

[0032] The locking component includes a sliding groove 3 formed on the telescopic rod 101 and a locking block 301 slidably connected in the sliding groove 3. A second spring 302 is provided in the sliding groove 3. One end of the second spring 302 is fixedly connected to the locking block 301, and the other end is fixedly connected to the inner wall of the sliding groove 3.

[0033] When the height of the mounting bracket needs to be adjusted, first press the locking block 301 to overcome the elastic force of the second spring 302 and exit from the corresponding adjustment hole 303. Then slide the telescopic rod 101 to move to the appropriate height in the insertion slot. At this time, under the action of the second spring 302, the locking block 301 is inserted into the corresponding adjustment hole 303 to lock the position of the telescopic rod 101.

[0034] In summary, the insertion and connection of the telescopic rod 101 and the reinforcing rod 1, along with the design of the locking components, allows the height of the mounting frame to be flexibly adjusted according to the actual installation environment and requirements. By adjusting the height of the mounting frame, the camera body 5 can be positioned at the optimal shooting position, meeting the requirements of different mine roadway heights and monitoring angles, thus improving the applicability of the mounting frame and the monitoring effect of the camera. At the same time, the cooperation between the spring 2 302 and the locking block 301 ensures that the telescopic rod 101 is stably fixed in the adjusted position, preventing the telescopic rod 101 from sliding due to vibration or other factors, and ensuring the stability of the mounting frame.

[0035] Example 4:

[0036] Reference Figure 1 , Figure 2 The suspended mounting frame and the intrinsically safe camera for mining are basically the same as in Embodiment 1. Furthermore, they also include multiple fixing bolts 501. The camera body 5 is detachably connected to the fixing rod 203 through multiple fixing bolts 501.

[0037] The connection method using multiple fixing bolts 501 provides greater connection force, making the connection between the camera body 5 and the fixing rod 203 more secure and reliable. It can withstand the vibration and impact in the mine environment, preventing the camera body 5 from loosening or falling off. At the same time, the connection and disassembly of the fixing bolts 501 are relatively simple, making it easier for workers to install and maintain the equipment, thus improving work efficiency.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model.
