The driving mechanism 300 can be a telescopic motor, and the telescopic push rod of the telescopic motor is connected with the rear side of the shuttle 200, so as to push the shuttle 200 to reciprocate forward and backward. Of course, the driving mechanism 300 can also be an electric telescopic cylinder.

[0040] The movable column 400 has a limiting state and a retracted state, and the movable column 400 is installed on the front side of the shuttle 200 to realize the switching of the limiting state and the retracted state. The movable column 400 in the limiting state is used to limit the front side of the tunnel inspection vehicle 101 on the shuttle 200, so as to stabilize the position of the tunnel inspection vehicle 101. The movable column 400 in the retracted state is lower than or flush with the upper end surface of the shuttle 200, so as to avoid the movable path of the tunnel inspection vehicle 101 moving along the front-rear direction, thereby unlocking the tunnel inspection vehicle 101, so that when the tunnel inspection vehicle 101 needs to go up the track 102, the tunnel inspection vehicle 101 can move forward into the track.

[0041] The utility model provides a tunnel inspection car upper and lower rail mechanism in one preferred embodiment, through set up along the front -back direction sliding installation in the receiving platform 100's pick -up car 200 and be used for driving pick -up car reciprocating sliding drive mechanism 300, realized the automatic pushing and receiving of tunnel inspection car 101. Compared with the traditional manual rail and derailment mode, the tedious steps of manual operation are greatly reduced, the efficiency of the inspection car upper and lower rail is significantly improved, a large amount of manpower and time cost are saved, the inspection car can be more quickly put into work or recovered after work, and the overall working efficiency of tunnel inspection is improved. The upper end surface of the pick -up car 200 is provided with a positioning edge column 210, which can abut and position the rear side and the left and right sides of the tunnel inspection car 101, and ensure the stable placement of the inspection car on the pick -up car. In addition, the movable column 400 has a limiting state and a retracted state. When in the limiting state, the front side of the inspection car on the pick -up car 200 can be limited to prevent displacement or falling on the receiving platform. When in the retracted state, the movable column is lower than or flush with the upper end surface of the pick -up car, avoiding hindering the forward and backward movement of the inspection car. This design effectively avoids the potential safety hazards of inaccurate alignment, inspection car shaking or falling during manual operation, ensuring the safety of the inspection car and the operator. The entire upper and lower rail process is automatically completed by the drive mechanism, and the operator does not need to directly contact the inspection car for operation. Only the start and stop of the drive mechanism need to be controlled, and the upper and lower rail of the inspection car can be easily realized, greatly reducing the operation difficulty and labor intensity, and improving the convenience and comfort of operation. At the same time, the mechanism has compact structure and reasonable layout, and can well adapt to the narrow and complex space environment in the tunnel, further enhancing its applicability and flexibility in practical application. In addition, the receiving platform can also be designed to be adjustable in height, so that when the inspection car is put on or taken off the rail, the receiving platform can be lowered to the appropriate position, facilitating the taking and placing of the inspection car. When the inspection car is working normally, the receiving platform can be raised to avoid the rail, leaving enough space for the operation of the inspection car. This ingenious space utilization method not only ensures the convenience of the inspection car upper and lower rail, but also does not affect the normal operation of other equipment and work in the tunnel, improves the utilization rate of the tunnel space, and reduces the mutual interference between equipment.

[0042] Referring to Figure 3 and Figure 4 In some embodiments of the utility model, the pick -up car 200 includes a top plate 220 and a bottom plate 230 spaced below the top plate 220, the bottom plate 230 and the side edge of the top plate 220 are connected and fixed through the side plate 240, so as to form an installation position between the bottom plate 230 and the top plate 220 for installing the movable column 400.

The movable column 400 bottom is equipped with the elastic member 430, to the movable column 400 with the elastic force that goes upwards. The press column 420 is spaced apart with the movable column 400 by using the transverse column 410 and avoids the movable path of the tunnel inspection vehicle 101 before and after activity, so that the press column 420 will not affect the tunnel inspection vehicle 101 before and after activity. The track 102 is equipped with the pressing plate 103, as shown in Figure 2 And Figure 4 The pick-up and drop-off position represents that the tunnel inspection vehicle 101 on the pick-up and drop-off vehicle 200 on the receiving platform 100 is aligned with the track 102, and the tunnel inspection vehicle 101 can be pushed on the track 102. When the receiving platform 100 is lifted to the pick-up and drop-off position, the upper end of the press column 420 is in contact with the pressing plate 103 and is pressed to the contracted state, and during the reciprocating movement of the top plate 220 at the pick-up and drop-off position, the upper end of the press column 420 is always in contact with the pressing plate 103 and is in the contracted state. That is, when the top plate 220 reaches the pick-up and drop-off position, due to the action of the pressing plate 103 pressing the press column 420, the movable column 400 is in the contracted state, so that the front side of the top plate 220 is not blocked by the structure of the tunnel inspection vehicle 101 entering or leaving, so that through the lifting movement of the receiving platform 100 and the cooperation of the pressing plate 103 and the press column 420, when reaching the pick-up and drop-off position, the movable column 400 is automatically switched to the contracted state, and the pick-up and drop-off of the tunnel inspection vehicle 101 can be smoothly realized. As shown in Figure 3 The movable column 400 limits the front side of the tunnel inspection vehicle 101 during the lifting process of the receiving platform 100 and the pick-up and drop-off vehicle 200, so that its position is stable during the lifting process and will not fall or have positional deviation to cause structural interference and collision with the track 102. Since the upper end of the press column 420 is always in contact with the pressing plate 103 during the reciprocating movement of the top plate 220 at the pick-up and drop-off position, in order to reduce the frictional resistance, the upper end of the press column 420 is provided with a roller 421.

The first guide column 440 and the first guide hole 231 are used to realize lifting guidance, and the first guide column 440 is used to facilitate the installation of the compression spring, so that the movable column 400 is elastically and movably installed, and the limiting structure 441 prevents the first guide column 440 from being separated from the first guide hole 231, thereby realizing stable installation. Specifically, the first guide column 440 is provided with a stud at the bottom, and the limiting structure 441 is a nut mounted on the stud. The nut has a larger profile than the first guide hole 231, and the nut cannot pass through the first guide hole 231, thereby limiting the movement range of the first guide column 440.

[0046] Referring to Figure 4 and Figure 5 In further embodiments of the present application, the pressing column 420 is provided with a second guide column 422 at the bottom, and the bottom plate 230 is provided with a second guide hole 232 for the second guide column 422 to insert, thereby realizing multi-position guidance and improving lifting stability.
