[0027] The present invention provides a multifunctional tunnel inspection platform, such as Figure 1-4 As shown, it includes a base 1 and a support base 2 slidably arranged on the base 1, a walking mechanism 3 is arranged between the support base 2 and the base 1, and the walking mechanism 3 can realize that the support base 2 can move forward and backward along the base 1. Specifically, a guide rail 7 is arranged on the base 1, and a guide wheel 8 matching the guide rail 7 is arranged at the bottom of the support base 2, and anti-rollover walking wheels 9 are clamped on both sides of the guide rail 7. Through the design of the anti-rollover walking wheels 9, the stability of the support base 2 when moving forward and backward along the base 1 can be ensured, and the rollover problem of the support base 2 can be avoided. 3 comprises a travel motor 10 arranged at one end of the base 1, a driving wheel is arranged on the output shaft of the travel motor 10, a driven wheel 11 is arranged at the other end of the base 1 at a position corresponding to the driving wheel, and a chain connected to the support base 2 is arranged on the driving wheel and the driven wheel 11, and the travel motor 10 drives the driving wheel to rotate forward or reverse, so that the support base 2 can be driven by the chain to move forward or backward along the guide rail 7 on the base 1, and the speed of the support base 2 moving forward or backward along the guide rail 7 on the base 1 can be adjusted by adjusting the speed of the travel motor 10.

[0028] At least two lifting platforms 4 that can move up and down are symmetrically arranged on the support seat 2 to realize bidirectional operation on the support seat 2. The lifting platform 4 can be telescopically moved left and right through a telescopic mechanism 5 and is arranged on the support seat 2. Specifically, the telescopic mechanism 5 includes a telescopic sleeve 12 and a telescopic cylinder 13 arranged on a telescopic support frame 16. The telescopic sleeve 12 and the telescopic cylinder 13 are each provided with two. The telescopic sleeve 12 includes a first sleeve 17, a second sleeve 18 and a third sleeve 19 that are slidably connected from the inside to the outside in sequence. Specifically, wear-resistant plates are provided between the first sleeve 17 and the second sleeve 18 and between the second sleeve 18 and the third sleeve 19 to prevent sliding wear between the sleeves. The first sleeve 17 is connected to the lifting platform 4, and the third sleeve 19 is fixedly connected to the telescopic support frame 16. The telescopic cylinder 13 includes a first cylinder 20 and a second cylinder 21. The first cylinder 20 is slidably connected to the telescopic support frame 16, and its telescopic end is connected to the lifting platform 4. Specifically, A sliding block and a sliding groove that cooperate with each other are provided between the first oil cylinder 20 and the telescopic support frame 16. The second oil cylinder 21 is fixed on the telescopic support frame 16, and its telescopic end is connected with the second sleeve 18 and the first oil cylinder 20. When working, the telescopic movement of the first oil cylinder 20 can push the lifting platform 4 to drive the first sleeve 17 along the second sleeve 18 to realize the first-level telescopic movement. The telescopic movement of the second oil cylinder 21 can push the second sleeve 18 along the third sleeve 19 and push the first oil cylinder 20 along the telescopic support frame 16 to drive the lifting platform 4 after the first-level telescopic movement to realize the second-level telescopic movement. Through the cooperation of the first-level telescopic movement and the second-level telescopic movement, the left and right telescopic movement of the lifting platform 4 on the support seat 2 can be realized. Furthermore, the telescopic direction of the telescopic mechanism 5 is perpendicular to the walking direction of the support seat 2. The lifting direction of the lifting platform 4 is perpendicular to the telescopic direction of the telescopic mechanism 5 and the walking direction of the support seat 2. Through the movement cooperation of the above three, the three-dimensional direction of the detection position can be arbitrarily adjusted.

[0029] One end of the telescopic mechanism 5 is rotatably connected to the support seat 2, and a balancing mechanism 6 is provided between the other end and the support seat 2. Specifically, one end of the telescopic support frame 16 is hinged to the support seat 2, and the other end is connected to the balancing mechanism 6 between the support seat 2. The balancing mechanism 6 includes a telescopic cylinder 14 that can move up and down, one end of the telescopic cylinder 14 is fixed on the support seat 2, and the other end is connected to the telescopic support frame 16. When the lifting platform 4 is telescopically moved left and right under the action of the telescopic mechanism 5, the force of the lifting platform 4 on the telescopic mechanism 5 changes, and a tilting phenomenon will occur. Therefore, when the lifting platform 4 extends outward, the telescopic cylinder 14 contracts downward, and when the lifting platform 4 is retracted inward, the telescopic cylinder 14 extends upward. That is, through the rotational connection between the telescopic mechanism 5 and the support seat 2 and the design of the balancing mechanism 6, the stability of the lifting platform can be adaptively adjusted when the lifting platform 4 is telescopically adjusted to the left and right positions.

[0030] Furthermore, a storage bin 15 is provided at one end of the base 1, and the storage bin 15 is arranged at the end of the base 1 where the travel motor 10 is provided. Through the design of the storage bin 15, the travel motor 10 can be protected, and at the same time, the support base 2 can be convenient for walking and retrieving the storage bin 15 when there is no operation, which can provide sun protection, rain protection and dust prevention, thereby increasing the service life of the equipment.

[0031] To sum up, the multifunctional working platform for tunnel inspection provided by the present invention has a simple structure and is easy to operate. It realizes the functions of automatic walking, automatic speed regulation and two-way operation. It has the advantages of flexible direction adjustment, high re-inspection accuracy, low cost, safety and portability, and improves inspection efficiency and saves manpower and material resources.
