Description

Technical Field

[0001] This utility model relates to the field of mine safety technology, and specifically discloses a sensor lifting device. Background Technology

[0002] In underground coal mine operations, the installation and calibration of sensors are crucial for ensuring safe production. However, existing sensor installation methods mostly involve suspending sensor frames from the tunnel ceiling, which suffers from problems such as improper hanging, poor stability, and inconvenient calibration. Especially when operators are installing, maintaining, and calibrating sensors, they often need to work at heights, which poses significant safety risks and causes numerous inconveniences for the operators.

[0003] Chinese patent CN109231053A discloses a sensor lifting device, comprising: a lifter, a transmission component, a hanging rod for suspending sensors, and a transmission rod. The transmission component includes a steel wire rope and a hanging component. A hanging component for suspending the steel wire rope is installed on the tunnel roof. The lifter is installed on the tunnel side. The steel wire rope wound around the lifter passes over the hanging component, and the end of the steel wire rope is connected to the end of the transmission rod or the middle of the hanging rod. The transmission rod is an adjustable telescopic rod. The upper end of the transmission rod is hinged to the hanging rod, and the lower end is hinged to a hinge seat on the tunnel side. The sensor cable passes through the cavity of the transmission rod and finally exits through the wire hole of the transmission rod. The hanging rod has several through holes for suspending sensors.

[0004] The aforementioned document discloses a sensor lifting device that directly suspends the sensor on the top of the tunnel using a steel wire rope. However, the sensor is easily affected by wind in the tunnel, causing it to sway and become unstable during lifting, which can easily affect the monitoring results. Therefore, a sensor lifting device is needed to solve this problem. Utility Model Content

[0005] This utility model proposes a sensor lifting device, which, through the cooperation of a scissor-type telescopic frame and a lifting device, achieves flexible adjustment and stable lifting of the sensor height, making it easy to maintain and safe and reliable.

[0006] This utility model is implemented as follows: a sensor lifting device includes a sensor body installed in a tunnel. Two supports are fixedly connected to the top of the tunnel. Two first sliders are provided on the outer walls of the two supports. The two first sliders on the left are fixedly connected to the two supports respectively, and the two first sliders on the right are slidably connected to the two supports respectively. An installation plate is provided below the supports. The sensor body is installed on the lower end face of the installation plate. Two sliding rods are fixedly connected to the upper end face of the installation plate through ear plates. Two second sliders are provided on the outer walls of the two sliding rods. The two second sliders on the left are fixedly connected to the two sliding rods respectively, and the two second sliders on the right are slidably connected to the two sliding rods respectively. A scissor-type telescopic frame is movably arranged between the four first sliders and the four second sliders.

[0007] A lifting device is installed on the side of the tunnel, and a pulling rope is wrapped around the outer wall of the lifting device. The other end of the pulling rope is fixedly connected to the mounting plate.

[0008] As a preferred embodiment of the sensor lifting device of this utility model, the top and side walls of the tunnel are provided with multiple pulleys for limiting the position of the traction rope.

[0009] As a preferred embodiment of the sensor lifting device of this utility model, the sidewall of the tunnel is hinged with a hollow telescopic rod via a hinge seat, and the other end of the telescopic rod is hinged to the outer wall of the mounting plate.

[0010] As a preferred embodiment of the sensor lifting device of this utility model, the telescopic rod includes a first sleeve and a second sleeve, the second sleeve is slidably connected to the inner wall of the first sleeve, and a fixing bolt is threadedly connected to the outer wall of the first sleeve, the threaded end of the fixing bolt abutting against the second sleeve.

[0011] As a preferred embodiment of the sensor lifting device of this utility model, the lifting device is a hand-cranked lifting device with a self-locking function.

[0012] In a preferred embodiment of the sensor lifting device of this utility model, the pulling rope is a steel wire rope.

[0013] The beneficial effects of this utility model are:

[0014] 1. By using a scissor-type telescopic frame in conjunction with a lifting device, the height of the sensor body can be adjusted smoothly and precisely to adapt to different working conditions. When maintenance or calibration is required, simply operate the lifting device to release the pull rope, and the sensor will descend to its lowest position, making operation convenient and improving maintenance efficiency.

[0015] 2. A scissor-type telescopic frame is used as the lifting mechanism, coupled with a slider guide, to ensure a smooth and undisturbed lifting process. Furthermore, the combination of wire rope and a self-locking lifting device enhances the load-bearing capacity and safety of the device, preventing accidental falls, making it suitable for complex environments such as mines and tunnels.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0023] Please see Figure 1-4A sensor lifting device includes a sensor body 2 installed in a tunnel 1. Two supports 6 are fixedly connected to the top of the tunnel 1. Two first sliders 7 are provided on the outer walls of the two supports 6. The two first sliders 7 on the left side are fixedly connected to the two supports 6 respectively, and the two first sliders 7 on the right side are slidably connected to the two supports 6 respectively. An installation plate 8 is provided below the supports 6. The sensor body 2 is installed on the lower end face of the installation plate 8. Two sliding rods 9 are fixedly connected to the upper end face of the installation plate 8 through ear plates. Two second sliders 10 are provided on the outer walls of the two sliding rods 9. The two second sliders 10 on the left side are fixedly connected to the two sliding rods 9 respectively, and the two second sliders 10 on the right side are slidably connected to the two sliding rods 9 respectively. A scissor-type telescopic frame 11 is movably arranged between the four first sliders 7 and the four second sliders 10.

[0024] A lifting device 3 is installed on the side of the tunnel 1. A pulling rope 5 is wrapped around the outer wall of the lifting device 3. The other end of the pulling rope 5 is fixedly connected to the mounting plate 8.

[0025] In this embodiment: when the sensor needs to be raised, the lifting device 3 tightens the pull rope 5, pulling the mounting plate 8 upward. At this time, the first slider 7 on the right slides to the right along the bracket 6, the second slider 10 on the right slides to the right along the slide bar 9, and the scissor-type telescopic frame 11 gradually retracts, causing the mounting plate 8 to rise horizontally as a whole. Conversely, when the lifting device 3 releases the pull rope 5, the mounting plate 8 descends under the action of gravity, the scissor-type telescopic frame 11 unfolds, and the sensor descends to its lowest position, allowing for sensor maintenance and calibration. This structure enables flexible adjustment of the sensor at different heights within the tunnel 1 while maintaining stability during the lifting process.

[0026] As a technical optimization of this utility model, the top and side walls of the tunnel 1 are provided with multiple pulleys 4 for limiting the pull rope 5.

[0027] In this embodiment, multiple pulleys 4 facilitate the limiting of the pulling rope 5.

[0028] As a technical optimization of this utility model, the sidewall of the tunnel 1 is hinged with a hollow telescopic rod 12 through a hinge seat, and the other end of the telescopic rod 12 is hinged to the outer wall of the mounting plate 8.

[0029] In this embodiment, the telescopic rod 12 extends and retracts with the lifting and lowering of the mounting plate 8. By setting the hollow telescopic rod 12, it is convenient to pass the cable of the sensor body 2 through the telescopic rod 12 for protection.

[0030] As a technical optimization of this utility model, the telescopic rod 12 includes a first sleeve 1201 and a second sleeve 1202. The second sleeve 1202 is slidably connected to the inner wall of the first sleeve 1201. The outer wall of the first sleeve 1201 is penetrated and threadedly connected with a fixing bolt 1203. The threaded end of the fixing bolt 1203 abuts against the second sleeve 1202.

[0031] In this embodiment: tightening the fixing bolt 1203 facilitates fixing the second sleeve 1202 to the first sleeve 1201.

[0032] As a technical optimization of this utility model, the lifting device 3 adopts a hand-cranked lifting device with a self-locking function.

[0033] In this embodiment: the lifting device 3 can be a conventional hand-cranked lifting device available on the market. The lifting device 3 has a self-locking function, that is, when the hand crank stops, the wire rope also stops moving (the self-locking lifting device is existing technology and will not be described in detail).

[0034] As a technical optimization of this utility model, the pulling rope 5 is a steel wire rope.

[0035] In this embodiment, by setting the pulling rope 5 as a steel wire rope, the strength of the device can be improved and its service life can be extended.

[0036] The working principle and usage of this utility model are as follows: When it is necessary to raise the sensor, the lifting device 3 tightens the pull rope 5, pulling the mounting plate 8 upward. At this time, the first slider 7 on the right slides to the right along the bracket 6, the second slider 10 on the right slides to the right along the slide rod 9, and the scissor-type telescopic frame 11 gradually retracts, causing the mounting plate 8 to rise horizontally as a whole. Conversely, when the lifting device 3 releases the pull rope 5, the mounting plate 8 descends under the action of gravity, the scissor-type telescopic frame 11 unfolds, and the sensor descends to its lowest position, allowing for sensor maintenance and adjustment. This structure enables flexible adjustment of the sensor at different heights within the tunnel 1 while maintaining stability during the lifting process.

[0037] In the description of this utility model, it should be understood that the terms "left", "right", "up", "down", "top", "bottom", "front", "back", "inner", "outer", "back", "middle", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0038] However, the above description is only a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
