DETAILED DESCRIPTION

[0022] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0023] See also Figure 1-4 The utility model provides a technical solution: a measuring device for measuring the damage degree of tunnel surrounding rock base, comprising a table 1, an engineering endoscope detection instrument 2 is placed on the surface of the table 1, a fixed shell 3 is fixedly connected to the surface of the engineering endoscope detection instrument 2, a line 4 is arranged inside the fixed shell 3, and both ends of the line 4 pass through the surface of the fixed shell 3, the surface of the line 4 is slidably connected to the inside of the fixed shell 3, one end of the line 4 is fixedly connected to the engineering endoscope detection instrument 2, and a detection probe 5 is fixedly connected to the end of the line 4 away from the engineering endoscope detection instrument 2, a fixed shell 8 is fixedly connected to the surface of the fixed shell 3, a rotating rod 9 is rotatably connected to the surface of the fixed shell 8, and the rotating rod 9 passes through the inside of the fixed shell 3, a pulley 13 is fixedly connected to the end of the rotating rod 9 located inside the fixed shell 3, and a rubber pad is arranged on the surface of the pulley 13 contacting the line 4, and a fixed block 14 is fixedly connected to the inner wall of the fixed shell 3, and the line 4 is limited by the setting of the pulley 13 and the fixed block 14, so that the line 4 is not allowed to slide freely inside the fixed shell 3.

[0024] When it is necessary to retract or release the line 4, the staff rotates the rotating rod 9. At the same time, due to the setting of the rubber pad on the surface of the pulley 13, the friction between the pulley 13 and the line 4 is increased when the pulley 13 rotates, and then the rotating rod 9 drives the pulley 13 to rotate, which pushes the line 4, and then pushes the line 4 to the outside of the fixed shell 3, completing the operation of releasing the line 4. At the same time, the rotating rod 9 is reversed, and the rotating rod 9 drives the line 4 to move toward the inside of the fixed shell 3 and retract. By rotating the rotating rod 9, the retraction and release of the line 4 can be completed. There is no need for two or more people to cooperate to complete the measurement and laying-out operation, which is convenient for the staff to use, saves manpower, and improves work efficiency.

[0025] Two slide grooves 16 are provided inside the fixed shell 3, and the inner walls of the two slide grooves 16 are slidably connected with second sliding rods 22, and the two second sliding rods 22 are arranged opposite to each other. The interior of the fixed shell 3 is rotatably connected with two threaded rods 17, and the two threaded rods 17 both penetrate into the interior of the fixed shell 28. The surfaces of the two threaded rods 17 are respectively connected with the internal threads of the two second sliding rods 22. The interior of the fixed shell 28 is rotatably connected with a rotating rod 2 19, and the surface of the rotating rod 2 19 is fixedly connected with a worm gear 20. The surface of the rotating rod 19 located inside the fixed shell 28 is fixedly connected with a worm 18, and the surface of the worm 18 is meshed with the surface of the worm gear 20. The surface of the rotating rod 2 19 is fixedly connected with two bevel gears 21, and the surfaces of the two threaded rods 17 located inside the fixed shell 28 are fixedly connected with bevel gears 21, and the bevel gears 21 on the surfaces of the two threaded rods 17 are respectively meshed with the bevel gears 21 on the surfaces of the two rotating rods 19.

[0026] When the rotating rod 19 rotates, the rotating rod 19 drives the worm 18 to rotate, and the worm 18 drives the rotating rod 2 19 and the worm wheel 20 to rotate. Since the surface of the rotating rod 2 19 and the surface of the threaded rod 17 are meshed and connected with the bevel gear 21, the rotating rod 2 19 drives the bevel gear 21 and the threaded rod 17 to rotate. Due to the setting of the slide groove 16, the second sliding rod 22 will not rotate with the threaded rod 17, but will slide inside the slide groove 16 as the threaded rod 17 rotates. The two second sliding rods 22 slide inside the fixed shell 3, and then the rotating rod 19 is rotated to send the line 4 outward. At the same time, the two second sliding rods 22 will move relative to each other and no longer straighten the line 4. When the line 4 is retracted into the fixed shell 3, as the rotating rod 19 is reversed, the two second sliding rods 22 will move away from each other to straighten the line 4, so that the line 4 located inside the fixed shell 3 is always in a straightened state, avoiding the situation where the line 4 is entangled, which is convenient for the staff to perform the line laying operation.

[0027] A fixing rod 6 is fixedly connected to the surface of the table top 1, and a fixing frame 7 is fixedly connected to one end of the fixing rod 6 away from the table top 1, and the fixing frame 7 is arranged in a ring shape. A sponge brush is arranged on the inner wall of the fixing frame 7. When the line 4 is laid out, the detection probe 5 and the line 4 are passed through the fixing frame 7, so that when the line 4 is pulled, the sponge brush inside the fixing frame 7 can sweep and clean the sand and soil attached to the surface of the line 4, thereby avoiding the sand and soil from adhering to the surface of the line 4, thereby avoiding the staff from rubbing and cleaning the line 4, and facilitating the use of the staff.

[0028] A first sliding rod 10 is fixedly connected to the bottom surface of the table top 1, and through holes 11 are arranged equidistantly on the surface of the first sliding rod 10. A supporting leg 15 is slidably connected to the surface of the first sliding rod 10, and a clamping rod 12 is slidably connected to the surface of the supporting leg 15. The height of the table top 1 can be adjusted by pulling out the clamping rod 12, so that the staff can place the table top 1 conveniently.

[0029] Working principle: the staff rotates the rotating rod 9, and the rotating rod 9 drives the pulley 13 to rotate to push the line 4, and then pushes the line 4 to the outside of the fixed shell 3, completing the operation of releasing the line 4, and at the same time, the rotating rod 9 is reversed, and the rotating rod 9 drives the line 4 to move toward the inside of the fixed shell 3 and retract. By rotating the rotating rod 9, the retraction and release of the line 4 can be completed.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
