Hydraulic cylinders 11 are respectively fixedly mounted on the back of several rotating blocks 1 5, and the output shafts of several hydraulic cylinders 11 are respectively fixedly connected to several rotating blocks 2 10.

[0031] When the bridge is being inspected, pressing button 29 on controller 28 activates multiple hydraulic cylinders 11, which drive the L-shaped robotic arm 8 to rotate upwards, placing the L-shaped robotic arm 8 onto the bridge's crash barrier.

[0032] Among them, such as Figure 5As shown, electric drive balance wheels 12 are fixedly installed on the top inner wall of several L-shaped robotic arms 8, electric drive balance wheels 23 are fixedly installed on the back inner wall of several L-shaped robotic arms 8, several hydraulic cylinders 24 are fixedly installed on the back of the support plate 2, and self-propelled wheels 35 are fixedly installed on the output shaft of several hydraulic cylinders 24.

[0033] By setting the restart hydraulic cylinder 11 to drive the L-shaped mechanical arm 8 to rotate downwards, the electric drive balancing wheels 12 and 213 on the L-shaped mechanical arm 8, together with the start hydraulic cylinder 214, drive the self-propelled wheel 315 to fix the bridge crash barrier. By using the hydraulic cylinders 11 and 214 to drive the electric drive balancing wheels 12, 213 and 315, the device can be fixed and moved, which is beneficial to improving the practicality of the device.

[0034] Among them, such as Figure 1 As shown, the configuration mechanism includes a hanging basket 16 threadedly mounted on the back of two support columns 1, a protective door 17 rotatably mounted on the hanging basket 16, a handle 18 fixedly mounted on the front of the protective door 17, and a ladder 19 threadedly mounted on the front of the support plate 2.

[0035] After the device is fixed in place, staff can pull handle 18 to rotate the protective door 17, open the hanging basket 16, and enter the hanging basket 16 for safe operation. When bridge inspection is required, it can be carried out through ladder 19.

[0036] Among them, such as Figure 4 As shown, a motor housing 20 is fixedly installed on the right side of the corresponding support plate 2. A motor 21 is fixedly installed on the inner wall of the right side of the motor housing 20. A rotating shaft 22 is fixedly installed on the output shaft of the motor 21. The rotating shaft 22 passes through the two support columns 1 and is rotatably connected to the two support columns 1.

[0037] By setting the motor 21, the rotating shaft 22 and the two worm gears 23 on the rotating shaft 22 will rotate synchronously.

Gears 26 are fixedly sleeved on the outer wall of the two rotating shafts 25 respectively. The two gears 26 mesh with the two worm gears 23 respectively. Moving wheels 27 are fixedly sleeved on the outer wall of the two rotating shafts 25 respectively.

[0039] By setting up two worm gears 23 meshing with two gears 26, the two worm gears 23 can drive the two gears 26 to rotate when they rotate, so that the rotating shaft 25 can drive the two moving wheels 27 on it to rotate and contact the guardrail, thereby enabling the device to move.

[0042] A specific application of this embodiment is as follows: During the test, pressing button 29 on controller 28 activates multiple hydraulic cylinders 11 to rotate the L-shaped mechanical arm 8 upwards, placing the L-shaped mechanical arm 8 into the bridge crash barrier. Then, hydraulic cylinders 11 are activated to rotate the L-shaped mechanical arm 8 downwards, causing the electric drive balancing wheels 12 and 13 on the L-shaped mechanical arm 8 to work in conjunction with hydraulic cylinder 214 to drive the self-propelled wheels 15, thus securing the bridge crash barrier. By using hydraulic cylinders 11 and 214 to drive the electric drive balancing wheels 12, 13, and 15, the device can be fixed and moved, improving its practicality. After the device is fixed, the operator can pull handle 18 to rotate the protective door 17, opening the hanging basket 16 and entering the basket. 6. For safe operation, when bridge inspection is required, it can be performed via ladder 19. When the device needs to be moved, press button 29 on controller 28 to start motor 21. Motor 21 will drive shaft 22 and the two worm gears 23 on shaft 22 to rotate synchronously. Since the two worm gears 23 mesh with the two gears 26, the rotation of the two worm gears 23 can drive the two gears 26 to rotate, so that the two shafts 25 can drive the two moving wheels 27 on them to rotate and contact the guardrail, thereby enabling the device to move. When the electric drive balance wheel 12 and electric drive balance wheel 23 are moving, when they encounter a road pole on the crash barrier, the L-shaped mechanical arm 8 in the forward direction will rise and fall individually in sequence, ensuring that at least 3 sets of hydraulically controlled telescopic L-shaped mechanical arms 8 form a safe support, thereby passing through the road pole on the crash barrier.
