Description

Technical Field

[0001] This application relates to the field of underground monitoring equipment technology, and in particular to a coal mine sensor lifting device. Background Technology

[0002] After the underground sensors are installed, they need to be calibrated regularly and their height set due to changes in the surrounding rock. However, due to the influence of the roadway height, the monitoring and maintenance personnel often need to use ladders to climb up the height when performing monthly probe calibration. When adjusting the sensor height, it is sometimes necessary to disassemble and reinstall the sensor. The uneven floor of the mining roadway makes climbing up the height dangerous and disassembling and reinstalling the sensor inconvenient, which consumes time, manpower and resources.

[0035] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] The coal mine sensor lifting device according to this application embodiment includes:

[0037] The system comprises a collection component 1 and a connecting rope 2. The collection component 1 is located on the sidewall and is adapted to collect or release the connecting rope 2. A pulley assembly 3 is located on the roof or the top of the sidewall. A mounting frame assembly 4 includes a mounting base 41, a first pulley 42, a rotating shaft 43, and a tilting adjustment frame 44. The mounting base 41 is located on the roof and has a first groove. The rotating shaft 43 is rotatably mounted in the first groove. One end of the tilting adjustment frame 44 is fitted onto the rotating shaft 43. The first pulley 42 is located at the end of the mounting base 41 adjacent to the collection component 1. The connecting rope 2 is wound sequentially around the pulley assembly 3 and the first pulley 42, and the connecting rope 2 is ultimately connected to the end of the tilting adjustment frame 44 away from the mounting base 41.

[0038] The collecting component 1 collects or releases the connecting rope 2 to adjust the rotation of the flipping adjustment frame 44.

[0039] The coal mine sensor lifting device of this application embodiment facilitates the adjustment of the sensor's monitoring angle and improves the flexibility of sensor monitoring.

[0040] Specifically, such as Figures 1 to 6 As shown, the collecting component 1 is installed on the side wall of the tunnel, and is adapted to collect and release the connecting rope 2. The pulley assembly 3 is installed on the top of the tunnel wall or on the roof to guide the connecting rope 2 during operation. The pulley assembly 3 is installed above the collecting component 1, or in other words, between the mounting collecting component 1 and the mounting frame assembly 4, so that the connecting rope 2 can run smoothly.

[0041] Mounting bracket assembly 4 is mounted on the top plate, and the sensor can be a wind speed sensor or other existing types of sensors.

[0042] Mounting base 41 is mounted on the top plate, and a first pulley 42 is provided at the lower end of mounting base 41. Rotating shaft 43 is disposed in the first groove. The rear end of the tilting adjustment frame 44 is sleeved in the rotating shaft 43, and the tilting adjustment frame 44 is rotatable in the vertical direction relative to mounting base 41 to adjust the relative angle of the tilting adjustment frame 44 with respect to the horizontal plane. It can be understood that the angle between the straight line extending from the tilting adjustment frame 44 and the horizontal plane changes as the tilting adjustment frame 44 rotates vertically, thereby monitoring equipment at different heights to adapt to different operating environments.

[0043] like Figure 1 As shown, the extension direction of the mounting bracket assembly 4 can be in the front-to-back direction, or as... Figure 2 As shown, in another embodiment, the mounting bracket assembly 4 can extend in the left and right directions to accommodate different monitoring needs.

[0044] In some embodiments, the coal mine sensor lifting device further includes a coil spring, which is sleeved on the rotating shaft 43. One end of the coil spring is connected to the mounting base 41, and the other end of the coil spring is connected to the tilting adjustment frame 44.

[0045] A coil spring is mounted on the rotating shaft 43 to ensure that the tilting adjustment frame 44 always tends to rotate backward in the vertical direction. When the collecting assembly 1 collects the connecting rope 2, the connecting rope 2 is collected onto the collecting assembly 1, and the tilting adjustment frame 44 rotates in the vertical direction and forward to move away from the mounting base 41 and the collecting assembly 1. After the collecting assembly 1 releases the connecting rope 2, the tilting adjustment frame 44 rotates forward. A sensor can be mounted on the tilting adjustment frame 44 to adjust the sensor's height and monitoring angle.

[0046] In some embodiments, the coal mine sensor lifting device further includes a connecting ring 5, which is located at the end of the tilting adjustment frame 44 away from the mounting base 41. The connecting rope 2 is connected to the connecting ring 5 after being wound around the pulley assembly 3 and the first pulley 42 in sequence.

[0047] The connecting ring 5 is located at the end of the tilting adjustment bracket 44 away from the mounting base 41, that is... Figure 1 The front end of the tilting adjustment frame 44 is located there. The collecting assembly 1 is adapted to collect and release the connecting rope 2. The connecting rope passes sequentially through the pulley assembly 3 and the first pulley 42, and finally connects to the connecting ring 5. By setting the connecting ring 5, the connecting rope 2 can be detachably mounted on it. In actual operation, when it is necessary to install or replace the coal mine sensor, the operator can quickly connect or disconnect the connecting rope 2 from the connecting ring 5, shortening the equipment installation and debugging time and improving work efficiency.

[0048] In some embodiments, the tilting adjustment frame 44 is provided with reflective strips, and multiple weight-reducing holes are provided in the extending direction of the tilting adjustment frame 44. In coal mine environments, the light is dim, and there is dust and smoke, which affects the visibility of personnel. After the tilting adjustment frame 44 is provided with reflective strips, when a light source, such as a miner's lamp or lighting equipment, shines on the reflective strips, the reflective strips will reflect the light back, making the tilting adjustment frame 44 more visible in the dim environment. Operators can more easily find the position and monitoring status or angle of the tilting adjustment frame 44, so that when the collecting component 1 collects and releases the tilting adjustment frame 44, they can see the rotation status of the tilting adjustment frame 44, and also avoid collisions with the tilting adjustment frame 44 during operation, effectively reducing the probability of safety accidents.

[0049] In some embodiments, the coal mine sensor lifting device further includes a sensor connecting frame 6, which is located at the end of the tilting adjustment frame 44 away from the mounting base 41. The sensor connecting frame 6 has multiple mounting slots for mounting sensors. Furthermore, the shape and size of the mounting slots can be matched to the shape of the sensor to restrict the movement of the sensor in all directions, preventing the sensor from being displaced or falling off due to vibration or shaking during device operation, thereby improving the stability and reliability of sensor installation.

[0050] In some embodiments, the coal mine sensor lifting device further includes anti-collision pads 7, and there are multiple anti-collision pads 7. These multiple anti-collision pads 7 are disposed on the upper and lower sides of the sensor connecting frame 6, and are spaced apart along the extending direction of the sensor support. For example... Figure 1As shown, anti-collision pads 7 are installed at the upper and lower ends of the sensor connecting frame 6, and multiple anti-collision pads 7 are installed on the upper and lower sides of the sensor connecting frame 6. When a collision occurs, the anti-collision pads 7 can absorb a large amount of impact energy through their own elastic deformation, transforming rigid collisions into flexible buffers, which greatly reduces the impact of impact force on the internal structure of the device and the sensor.

[0051] Because the anti-collision pads 7 are spaced apart and distributed on the upper and lower sides along the extension direction of the sensor bracket, they act as a buffer when impacts come from the front-to-back direction. Alternatively, when the device is subjected to a vertical impact, the anti-collision pads 7 at both ends can work together. Frequent collisions can cause fatigue damage to the device structure, reducing its strength and stability. By buffering collisions, the anti-collision pads 7 reduce the number of stress cycles and the stress amplitude experienced by the device structure, lowering the probability of structural fatigue damage, thereby extending the service life of the entire coal mine sensor lifting device and reducing equipment maintenance and replacement costs.

[0052] Alternatively, the buffering effect of the anti-collision pad 7 can reduce the impact force on the connecting parts, protect the integrity of other connecting parts on the sensor connecting frame 6, ensure that the connection between the various parts of the device is firm and reliable, and maintain the normal operation of the device.

[0053] In some embodiments, the collecting assembly 1 includes a drum 11, a handle 12, and a mounting plate 13. The handle 12 is connected to the drum 11, the mounting plate 13 is disposed on the side of the tunnel, the drum 11 is rotatably disposed on the mounting plate 13, and the drum 11 rotates relative to the mounting plate 13 to collect or release the connecting rope 2.

[0054] The drum 11 rotates to collect or release the connecting rope 2. The mounting plate 13 is positioned on the side of the tunnel, making full use of the space on the tunnel side, saving tunnel space, and leaving sufficient space for the placement of other equipment and personnel passage, thus improving tunnel utilization. It also avoids interference with the normal operation of the collecting component 1. The drum 11 rotates on the mounting plate 13, and the connecting rope 2 is collected and released along a preset path under the guidance of the pulley assembly 3, avoiding cross-interference with other equipment or lines.

[0055] In some embodiments, the handle 12 is provided with anti-slip texture. The anti-slip texture design allows the operator to grip the handle 12 more easily, reducing relative slippage between the hand and the handle 12, and reducing hand friction and fatigue. For example, after performing multiple sensor lifting operations in succession, the operator's hand will not exert excessive force due to frequent slippage, thereby reducing hand fatigue and improving operating comfort.

[0056] In some embodiments, a plurality of first holes are provided on the drum 11, and the plurality of first holes are spaced apart in the circumferential direction of the drum 11. The mounting plate 13 is provided with a plurality of second holes corresponding to the first holes.

[0057] For example, fasteners can be passed through the first and second holes to secure the drum 11 relative to the mounting plate 13, preventing the drum 11 from releasing or collecting the connecting rope 2 after the sensor installation is completed. The fasteners can be on-site reinforcing bars or bolts, allowing operators to restrict the rotation of the drum 11 using the fasteners.

[0058] In some embodiments, the pulley assembly 3 includes an anchor plate 31 and a second pulley 32. The anchor plate is disposed on the top of the roadway wall or the roof, and the second pulley is disposed on the anchor plate. The second pulley is disposed on the anchor plate, which is disposed on the upper end of the roadway wall or the roof, or the anchor plate is disposed on the anchor cable or anchor rod. The connecting rope 2 is wound or laid on the second pulley and the first pulley 42 in sequence from the drum 11, and finally connected to the connecting ring 5 on the tilting adjustment frame 44. The second pulley and the first pulley 42 guide the connecting rope 2 to make its operation smoother.

[0059] The foregoing has provided a detailed description of the method provided in this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this application.
