DETAILED DESCRIPTION

[0022] The following is combined with Figure 1-4 This application is described in further detail.

[0023] A walking type maintenance vehicle for bridge crash wall, referring to Figure 1 and Figure 2 , including a bracket upper part 100, a bracket lower part 200 and a bracket middle part 300 for connecting the bracket upper part 100 and the bracket lower part 200. The bracket upper part 100, the bracket middle part 300 and the bracket lower part 200 are all welded by angle steel to form a frame structure. The bracket upper part 100 is hooked on the top of the bridge crash wall in a curved shape, the bracket middle part 300 is attached to the side of the bridge crash wall, and the bracket lower part 200 is provided with a bearing seat to facilitate the staff to ride on the maintenance vehicle.

[0024] Reference Figure 1 and Figure 2 A connecting frame 110 is rotatably installed on the edge of the upper part 100 of the bracket. The connecting frame 110 is located at one end of the upper part 100 of the bracket hooked on the inner wall of the bridge crash barrier. The connecting frame 110 abuts against the inner wall of the bridge crash barrier, and a first torsion spring 120 is installed between the top of the connecting frame 110 and the upper part 100 of the bracket. The first end of the first torsion spring 120 abuts against the side of the connecting frame 110, and the second end of the first torsion spring 120 abuts against the side of the upper part 100 of the bracket, so that the connecting frame 110 is pressed tightly against the inner wall of the bridge crash barrier.

[0025] Reference Figure 3A first driving wheel 130 is rotatably mounted on the upper portion 100 of the bracket, and the first driving wheel 130 rolls against the surface of the bridge crash wall. A driving motor 140 is mounted on the upper portion 100 of the bracket, and the output shaft of the driving motor 140 is rotatably connected to the rotating shaft of the first driving wheel 130. The driving motor 140 controls the first driving wheel 130 to rotate, so that the maintenance vehicle moves along the bridge crash wall.

[0026] Reference Figure 3 , the two sides of the middle part 300 of the bracket are respectively rotatably mounted with auxiliary frames 310. Specifically, a fixing seat 320 is fixedly mounted on the side of the middle part 300 of the bracket, and a rotation hole is opened in the interior of the fixing seat 320 along the vertical direction. The auxiliary frame 310 includes two first auxiliary rods 311 and a second auxiliary rod 312. The second auxiliary rod 312 is parallel to the length direction of the middle part 300 of the bracket. The two ends of the second auxiliary rod 312 are respectively connected to the two first auxiliary rods 311. The end of the first auxiliary rod 311 away from the second auxiliary rod 312 is installed with a rotating vertical axis, and the rotating vertical axis is rotatably installed and connected in the rotating hole of the fixing seat 320. When the maintenance vehicle is out of use, the auxiliary rod is folded around the rotating vertical axis on the side of the middle part 300 of the bracket to reduce the occupied space of the maintenance vehicle. A connecting hook 330 is also installed on the side of the middle part 300 of the bracket. The connecting hook 330 is hooked on the second auxiliary rod 312, so that the auxiliary frame 310 can be stably folded on the side of the middle part 300 of the bracket.

[0027] Reference Figure 3 and Figure 4The second auxiliary rod 312 is rotatably mounted with an auxiliary wheel 313, and the auxiliary wheel 313 is used to abut against the outer wall of the bridge crash barrier. The rod body of the first auxiliary rod 311 is provided with a first limiting protrusion 340 and a second limiting protrusion 350, and a distance is reserved between the first limiting protrusion 340 and the second limiting protrusion 350, and the first limiting protrusion 340 and the second limiting protrusion 350 are both protruding from the rod body surface of the first auxiliary rod 311. The first auxiliary rod 311 is slidably mounted with a sliding sleeve 360, and the sliding sleeve 360 ​​is located between the first limiting protrusion 340 and the second limiting protrusion 350, and the distance between the first limiting protrusion 340 and the second limiting protrusion 350 is greater than the length of the sliding sleeve 360, so that the sliding sleeve 360 ​​can move between the first limiting protrusion 340 and the second limiting protrusion 350. A first spring 370 and a second spring 380 are also installed between the first limiting protrusion 340 and the second limiting protrusion 350. The first end of the first spring 370 abuts against the end of the first limiting protrusion 340, the second end of the first spring 370 abuts against the first end of the sliding sleeve 360, the first end of the second spring 380 abuts against the end of the second limiting protrusion 350, and the second end of the second spring 380 abuts against the second end of the sliding sleeve 360. A connecting ring 361 is installed on the side of the sliding sleeve 360, and a connecting rod 390 is rotatably installed on the side of the bracket middle part 300. The first end of the connecting rod 390 is rotatably connected to the bracket middle part 300, and the second end of the connecting rod 390 is installed with a hook 391, which is used to hook with the connecting ring 361. The connecting rod 390 is used to support the auxiliary frame 310 to abut against the outer wall of the bridge anti-collision wall.

[0028] The implementation principle of the embodiment of the present application is: when the maintenance vehicle is installed on the bridge crash barrier, the auxiliary frame 310 is rotated around the vertical axis of rotation so that the auxiliary frame 310 rotates toward the outer wall of the bridge crash barrier. The middle part 300 of the bracket and the auxiliary frame 310 are relatively fixed using the connecting rod 390 so that the auxiliary frame 310 is in an unfolded state. The auxiliary wheels 313 on the second auxiliary frame 310 are rolled against the outer wall of the bridge crash barrier. When the driving motor 140 drives the maintenance vehicle to move, the auxiliary frame 310 increases the stability of the middle part 300 of the bracket in the width direction. The first spring 370 and the second spring 380 are used to increase the flexibility between the auxiliary frame 310 and the connecting rod 390.

[0029] When the maintenance vehicle is out of use, the auxiliary frame 310 rotates around the vertical axis toward the side of the middle part 300 of the bracket until it fits against the side of the middle part 300 of the bracket, and is hooked on the second auxiliary frame 310 by the connecting hook 330, so that the auxiliary frame 310 is in a folded state and fixed to the middle part 300 of the bracket.

[0030] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
