DETAILED DESCRIPTION

[0014] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] like Figure 1-Figure 5 As shown, a sensor hanging frame lifting device comprises a hanging frame 1 and a supporting frame 2, wherein a vertical supporting frame 2 is fixed to the bottom end of the hanging frame 1, and a vertical double-acting cylinder 3 is fixed to the hanging frame 1 and the supporting frame 2 together, wherein the piston rod of the double-acting cylinder 3 passes through the bottom of the hanging frame 1, and a vertical lower supporting seat 4 is fixed to the top of the piston rod of the double-acting cylinder 3, and a vertical upper supporting seat 5 is fixed to the bottom end of the upper part of the hanging frame 1, and the upper supporting seat 5 is rotatably connected to a No. 2 pulley 6, and the lower supporting seat 4 is rotatably connected to a No. 3 pulley 7 and a No. 1 pulley 8 from left to right in sequence, and the No. 2 pulley 6, the No. 3 pulley 7 and the No. 1 pulley 8 Parallel to each other, a three-position four-way reversing valve 9 is fixed at the bottom end of the support frame 2, and the three-position four-way reversing valve 9 is manually controlled. The A port and B port of the three-position four-way reversing valve 9 are connected with the two air ports of the double-acting cylinder 3 through a pneumatic hose, and the P port of the three-position four-way reversing valve 9 is connected with the external air source through a pneumatic hose, and the T port of the three-position four-way reversing valve 9 is connected with the external air. The cable 10 passes through the upper part of the hanging frame 1 and is bent through the first pulley 8, the second pulley 6, and the third pulley 7 in sequence and is fixed to the bottom end of the upper part of the hanging frame 1. A threaded hole 11 is opened at the rear of the hanging frame 1, and a cleaning mechanism 12 is installed.

[0016] When in use, the upper end of the cable 10 is fixed somewhere on the top of the tunnel, and then the gas detection sensor is installed on the back of the hanging bracket 1 using the threaded hole 11. By controlling the three-position four-way reversing valve 9, the airway passage can be changed, so that the piston rod of the double-acting cylinder 3 can be extended and retracted, and then the distance between the upper support seat 5 and the lower support seat 4 can be changed, so that the hanging bracket 1 can be raised and lowered compared to the tunnel through the cable 10, and then the height position of the sensor compared to the tunnel is changed, so that the sensor can be easily inspected and maintained.

[0017] The cleaning mechanism 12 includes an upper support shaft 13, a lower support shaft 14, a pulley 15, a belt 16, a transmission rod 17, a third support shaft 18, a brush roller 19, and a shield 20. The right part of the hanging frame 1 is rotatably connected with a horizontal upper support shaft 13 and a lower support shaft 14 in sequence from top to bottom. The upper support shaft 13 and the lower support shaft 14 are respectively coaxially rotatably connected with the pulley 15, and the two pulleys 15 are rotatably connected with the belt 16 together. A horizontal transmission rod 17 is fixed to the right part of the lower support seat 4, and the transmission rod 17 is plugged with the belt 16. The upper part of the hanging frame 1 is rotatably connected with a vertical third support shaft 18 running through it from top to bottom. The third support shaft 18 is transmission-connected with the upper support shaft 13 through the meshing of bevel gears. A brush roller 19 is coaxially fixed to the upper part of the upper support shaft 13, and the bristles of the brush roller 19 are always in contact with the cable 10. The front part of the hanging frame 1 is closed and fastened with a shield 20 by bolts.

[0018] Furthermore, when the double-acting cylinder 3 retracts and extends the piston rod, the belt 16 can be rotated through the transmission rod 17, thereby driving the upper support shaft 13 and the lower support shaft 14 to rotate through the pulley 15, and then the brush roller 19 is rotated through the bevel gear and the third support shaft 18, so that the surface of the cable 10 can be cleaned, and the mineral dust attached to the surface of the cable 10 is reduced from entering the protective cover 20, thereby reducing the interference of the mineral dust on the pulley 15, the belt 16, the first pulley 8, the second pulley 6 and the third pulley 7, so as to reduce wear.

[0019] The protective cover 20 is made of transparent material, and the cable 10 is a steel wire cable 10. A screw barrel 21 is slidably connected to the front of the protective cover 20, and the sliding direction of the screw barrel 21 is reciprocating between the front upper and the rear lower. A support plate 22 is fixed along the circumference of the rear of the screw barrel 21, and a sponge 23 is fixed to the rear end of the support plate 22. The sponge 23 is connected to the hollow part of the screw barrel 21, and a guide groove 24 is opened on the outer wall of the screw barrel 21 in the axial direction. The screw barrel 21 is slidably connected to the protective cover 20 through the guide groove 24. A nut 25 is coaxially threadedly connected to the outer wall of the screw barrel 21, and a screw cover 26 is threadedly connected to the front end. The screw barrel 21 has a tendency to slide backward and downward along the protective cover 20 under the action of gravity, and the rear end of the nut 25 can be pressed against the front of the protective cover 20 under the action of gravity.

[0020] Furthermore, the front and rear positions of the screw barrel 21 relative to the protective cover 20 can be adjusted by rotating the nut 25 forward and backward. When the screw barrel 21 moves backward to a certain position, the sponge 23 can be made to contact the surface of the cable 10. At this time, the screw cover 26 is removed, and anti-rust oil is poured into the screw barrel 21. The anti-rust oil can be applied to the surface of the cable 10 through the sponge 23, thereby performing an anti-rust treatment on the cable 10 and extending its service life.

[0021] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
