[0033] Embodiment 1:

[0034] As attached Figure 1 To Attachment Figure 3 As shown:

[0035] The present invention provides a tunnel inspection vehicle. The track of the tunnel inspection vehicle adopts a 38kg / m track 2 with a height of 93mm and a width of 93mm. The track is arranged on both sides of the tunnel wall. The distance between the two tracks 2 is 9.59m. The track 2 includes a mounting frame and an I-shaped steel rail 22. The mounting frame is installed on the tunnel wall 1 through an anchor bolt 3. The I-shaped steel rail 22 is vertically arranged on the mounting frame. The mounting frame is fixed to the tunnel wall by a mounting frame contacting the bottom of the rail, a stainless steel clamping plate and a chemical anchor bolt 3.

[0036] A frame 5 is provided on the two tracks 2, and both ends of the frame 5 are slidably connected to the tracks 2 through a walking mechanism 4. A platform 7 is provided on the frame 5. Maintenance personnel can enter the platform 7 on the inspection vehicle from the left and right sides to perform maintenance work on the tunnel. The inspection vehicle ensures the passage of two lanes during use, reducing the impact on traffic;

[0037] The traveling mechanism 4 comprises a driving box with an opening at the bottom, in which a driving wheel is rotatably connected, and the driving wheel extends out of the driving box and contacts the I-shaped rail 22 on the track 2. A motor is arranged on the side of the driving box to connect the driving wheel axle, so as to realize the forward and backward movement of the inspection vehicle; and the driving wheel support width is greater than the width of the I-shaped rail 22, and the wheel body is widened so as to reserve lateral adaptation space with an adaptation range of ±50mm, so as to overcome the driving asynchronism or installation error of the track gauge of the inspection vehicle that may occur during the movement of the inspection vehicle, so that the traveling wheel of the inspection vehicle is not stuck, thereby avoiding deformation and damage of the track 2 or the truss.

[0038] The frame 5 is a trapezoidal truss structure, and the legs on both sides of the frame 5 are in an eight-shaped support to increase the structural stability of the entire inspection vehicle. Wheel frames are provided on the legs at both ends of the frame 5, and guide wheels 6 are rotatably provided on the wheel frames. The guide wheels 6 roll with the tunnel wall 1. When the inspection vehicle is moving, the guide wheels 6 roll and rub with the tunnel wall 1 to increase stability.

[0039] In addition, a guardrail 9 is provided on the platform 7 to protect the workers during the maintenance process, and a notch is provided on the guardrail 9 corresponding to the axial position of the jet fan in the tunnel. A gantry is movably provided at the two notches of the guardrail 9. The gantry can be slid at the tunnel jet fan so that the gantry is opened to reveal the notch, and the inspection vehicle can pass the fan smoothly. On the one hand, a slide groove is provided on the platform 7 along the length direction, and the bottom of the gantry is slidably stuck in the slide groove, and the gantry slides and overlaps at the guardrail 9 to reveal the notch. On the other hand, the gantry can also be hinged on one side of the notch in the guardrail 9 or the bottom of the gantry is hinged on the platform 7, and the notch is revealed by flipping the gantry.

[0040] Embodiment 2:

[0041] As attached Figure 4 To Attachment Figure 7 As shown:

[0042] The difference between this embodiment and the first embodiment is that a yield structure is designed for the track 2 at the tunnel shelter, including mounting plates 201 arranged on the inner walls of both sides of the shelter, a notch is opened in the track 2 at the shelter, so that the track 2 is disconnected to avoid blocking the shelter, a slide rail 202 is arranged on the mounting plate 201, a slider 204 is provided in the slide rail 202, a connecting platform 206 is arranged between the two sliders 204, the movement of the slider 204 can drive the connecting platform 206 to connect the track 2 on both sides of the notch, before the inspection vehicle passes through the shelter, the connecting platform 206 is moved out by an automatic mechanism to fill the notch on the track 2, so that the inspection vehicle can pass through the shelter smoothly, in this embodiment, a threaded rod 203 is rotatably arranged in the slide rail 202, the threaded rod 203 passes through the slider 204 and is threadedly connected to the slider 204, one end of the threaded rod 203 is connected to a motor, driving the threaded rod 203 to rotate can control the movement of the slider 204, thereby controlling the movement of the connecting platform 206;

[0043] And as Figure 7 As shown, the connecting platform 206 is connected to the slider 204 through the bracket 205. When the inspection vehicle passes over the connecting platform 206, the force is entirely applied by the inclined bracket 205. Therefore, the track 2 is also improved in this embodiment, such as Figure 5 and Figure 6 As shown, the track 2 in this embodiment includes a hollow support body 21 and an I-shaped steel rail 22 on the support body 21, a swivel seat 11 and a worm 14 are respectively arranged in the support body 21, a worm wheel 12 meshing with the worm 14 is rotatably connected to the swivel seat 11, a screw rod 13 runs through the center of the worm wheel 12, and two ends of the screw rod 13 are respectively connected to a reinforcing frame 10 and a balancing frame 15, the screw rod 13 is threadedly connected to the worm wheel 12, the reinforcing frame 10 and the balancing frame 15 are slidably clamped in the inner cavity of the support body 21, the worm 14 is vertically rotatably connected in the support body 21 and driven by a motor, the motor drives the worm 14 to rotate and drive the worm wheel 12 to rotate, and when the worm wheel 12 rotates, the screw rod 13 threadedly connected thereto moves back and forth in the support body 21; since a connecting shell 207 matching the support body 21 is arranged at the bottom of the connecting platform 206, the movement of the screw rod 13 can drive the reinforcing frame 10 to slide into the connecting shell 207;

[0044] Before the walking mechanism passes through the escape tunnel, the connecting platform 206 moves to be flush with the track 2, and a photoelectric switch is provided at the end of the support body 21, and the photoelectric switch is connected to the motor circuit of the driving worm 14. The connecting platform 206 blocks the photoelectric switch at the end of the support body 21 and triggers the switch. At this time, the worm 14 works to drive the reinforcing frame 10 to slide into the connecting shell 207 to play a temporary support role, thereby strengthening the supporting strength of the connecting platform 206 for the inspection vehicle. After the inspection vehicle leaves, the reinforcing frame 10 and the connecting platform 206 can be retracted. The setting of the photoelectric switch enables the movement of the inspection vehicle and the support of the reinforcing frame 10 to be coordinated, thereby avoiding safety accidents such as the inspection vehicle easily collapses and the connecting platform 206 easily deforming due to the negligence of the staff in increasing the support of the reinforcing frame 10 when the inspection vehicle passes through the connecting platform 206.

[0045] The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
