The detector 10 is fixedly installed on the top of the second observation tube 4. A light filtering mechanism is provided inside the other end of the first observation tube 3. Two limiting mechanisms are symmetrically arranged on the top of the mobile vehicle frame 1.

[0027] When in use, by setting the first observation tube 3, the second observation tube 4 and a plurality of reflecting mirrors 7, an observation channel is formed. The height of the second observation tube 4 can be adjusted according to the height of the detection position, so as to send the detector 10 to the position to be detected. Through the observation channel, it can be checked at one end of the first observation tube 3 whether the detector 10 is accurately delivered, and timely adjustments can be made, improving the accuracy of the equipment for delivering the detector, and further improving the accuracy of the detection data.

[0028] The observation channel composed of the first observation tube 3 and the second observation tube 4 is provided with a reflector 7 at each corner, and the position of the detector 10 can be mapped to one end of the first observation tube 3 through the reflector 7 at all times, so that the operator can accurately adjust the height of the second observation tube 4 until the point to be detected can be observed. A magnet plate 701 and a metal positioning shaft 20 are provided, so that the reflector 7 can be adsorbed on the inclined square hole 19 by magnetic force, which is more convenient for assembly or disassembly. Through the limiting mechanism, the entire device can be limited while the second observation tube 4 is raised to avoid the shaking of the mobile frame 1 and improve the stability of the device in the working state. A filtering mechanism is provided to facilitate the staff to filter the light when observing the detection point through the observation channel to avoid strong light suddenly appearing in the observation channel and flashing to people's eyes, causing visual damage, thereby improving the practicality of the equipment.

[0029] In this embodiment, an electric telescopic rod 8 is fixedly installed on the top of the first observation tube 3, and the telescopic end of the electric telescopic rod 8 is fixedly installed on one side of the second observation tube 4. Handles 5 are fixedly installed on both opposite sides of the first observation tube 3, and a controller 16 for controlling the extension and retraction of the electric telescopic rod 8 is embedded on the surface of each handle 5.

The filtering mechanism includes a frame 15 and a dark-colored light-transmitting mirror 12, and the dark-colored light-transmitting mirror 12 is fixedly installed in the frame 15. A plurality of slide grooves 18 adapted to the frame 15 are opened inside one end of the first observation tube 3, and the plurality of slide grooves 18 all penetrate the surface of one side of the first observation tube 3. The plurality of frames 15 are respectively slidably installed in the plurality of slide grooves 18. A plurality of fastening bolts 17 are threadedly connected to one side of the first observation tube 3, and the plurality of fastening bolts 17 all penetrate the outer surface of the first observation tube 3 and abut against one side of the plurality of frames 15. A dust cover 6 is hinged at one end of the first observation tube 3.

[0030] When in use, a plurality of universal wheels are installed at the bottom of the mobile frame 1 to facilitate the transfer of the device. The mobile frame 1 is pushed by the handle 5 to push the entire device below the point to be detected, and then the electric telescopic rod 8 is started by the controller 16 at the handle 5 to drive the second observation tube 4 to rise in height. At the same time, the detector 10 is observed through one end of the first observation tube 3 to see whether it has been delivered to the monitoring point. A plurality of mirror frames 15 and a plurality of dark-colored translucent mirrors 12 are provided. The dark-colored translucent mirrors 12 can be provided with a variety of colors, so that the device can select a translucent mirror of a suitable color to filter the light in the observation channel according to the surrounding light environment during use. A dust cover 6 is provided to close the opening at one end of the first observation tube 3 when the device is in an idle state to prevent dust from entering the observation channel, thereby improving the practicability of the device.

[0031] In this embodiment, the limiting mechanism includes a limiting column 2 and an air cylinder 11. The limiting column 2 is a T-shaped cylindrical structure. The surfaces of the mobile frame 1 and the air cylinder 11 are provided with through holes that are compatible with the limiting column 2. The limiting column 2 is slidably installed in the through hole. A rubber block for anti-slip is detachably fixedly installed at the bottom of the limiting column 2. The air cylinder 11 is fixedly installed on the top of the mobile frame 1. A first air cavity 1101 and a second air cavity 1102 are provided in the air cylinder 11. A piston 1103 is slidably installed in the first air cavity 1101, and a push plate 21 is slidably installed in the second air cavity 1102. A plurality of push rods 13 are fixedly installed on the top of the push plate 21. The top ends of the plurality of push rods 13 pass through the outer surface of the air cylinder 11 and are fixedly connected to the top end of the limiting column 2. A reset spring 14 is sleeved on the surface of the limiting column 2. One end of the reset spring 14 is fixedly installed on the top of the limiting column 2, and the other end is fixedly installed on the surface of the air cylinder 11.

[0032] During use, when the second observation tube 4 rises driven by the electric telescopic rod 8, the top of the piston 1103 is no longer squeezed by the protrusion 9, and the limiting column 2 slides toward the ground under the action of its own gravity and the force of the return spring 14 until the rubber block at the bottom of the limiting column 2 is against the ground, and the return spring 14 always generates a downward pulling force on the limiting column 2, thereby improving the stability of the device during use. An air cylinder 11 is provided. When the device completes the detection work and needs to be transferred or stored, the second observation tube 4 is first lowered to the lowest position to facilitate a more stable device movement process. When the second observation tube 4 drops to a certain position, the piston 1103 is squeezed by the protrusion 9, and then air pressure is gradually generated in the first air cavity 1101 and the second air cavity 1102 to push the push block 21 to slide upward, and then the limiting column 2 is lifted by the push rod 13, so that the anti-sliding block is out of contact with the ground, so that the device can be transferred, thereby improving the linkage consistency of the device.

[0033] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: when in use, first open the dust cover 6, select a suitable dark-colored light-transmitting mirror 12 according to the on-site light environment, then push the device to the position below the point to be detected, start the electric telescopic rod 8 to drive the second observation tube 4 to rise, and observe whether the detection position is reached through one end of the first observation tube 3, and then accurately send the detector 10 to the detection point, thereby improving the accuracy of equipment detection. While the second observation tube 4 is rising, the limit column 2 slides toward the ground under the action of its own weight and the tension of the reset spring 14, and the limit column 2 drives the anti-sliding block to resist the ground, thereby improving the stability of the equipment during use and preventing the shaking of the equipment from affecting the accurate detection of the detector 10.

[0034] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
