Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bridge maintenance, in particular to a bridge maintenance and inspection device. Background Technique
[0002] Bridge maintenance refers to the inspection, detection, evaluation, and repair and reinforcement work carried out to ensure that the bridge is always in a normal working state. During the process of bridge maintenance, it is particularly necessary to inspect the state of the guardrail and the connection state between the bridge slab and the pier, and discover and solve problems in a timely manner.
[0003] The technical solution disclosed in the Chinese patent with the authorization announcement number CN216920009U can be installed on one side of the bridge alone through the main load-bearing beam, legs and pulleys by providing a connecting flange at the right end of the vertical suspension rod. It is also possible to arrange two identical devices on both sides of the bridge respectively, and connect them through the connecting flange of the vertical suspension rod and fix them with bolts. Then the two devices on the left and right are combined into an inspection device arranged in the gap between the two bridges, so that only one type of bridge inspection hanging basket needs to be designed to adapt to the inspection work of two bridge forms, greatly reducing the working cost. Moreover, the side pulleys, elastic pulleys and supporting devices can hold the bridge to increase the stability of the hanging basket. The main load-bearing beam of the utility model can slide in the sliding cylinder, so that the inside and outside movement of the hanging basket can be controlled to adapt to different inspection requirements. And this sliding function can also adapt to different bridge gaps when the two devices are butted and combined, so as to better carry out the connection operation.
[0004] However, this device still has deficiencies: when the device is actually used, it is troublesome for the staff to get on and off, and the risk factor is large. At the same time, when the main load-bearing beam slides along the inside of the sliding cylinder towards the counterweight block, the hanging basket is extremely easy to collide with the bridge.

Detailed implementation manners
[0023] Embodiment 1
[0024] Such as Figures 1-4As shown in the figure, a bridge maintenance and inspection device proposed by the utility model includes a vehicle body 1, a sliding frame 5, a lifting drive assembly, and a material transfer assembly. A column 2 is arranged on the vehicle body 1. A circular ring is arranged at one end of the support 3, and the circular ring is sleeved outside the column 2 and rotatably connected to the column 2. A drive assembly 4 for driving the support 3 to rotate is arranged on the vehicle body 1. The drive assembly includes a motor, a gear A, and a gear B. A reinforcing plate for fixing the column 2 is arranged on the vehicle body 1, the motor is connected to the reinforcing plate, and the motor is drivingly connected to the gear A. The gear B is connected to the circular ring, and the gear B is coaxial with the circular ring. The gear A meshes with the gear B. The sliding frames 5 are symmetrically arranged on the support 3 and slidably connected thereto. The two side sliding frames 5 are connected to the same mounting plate 6. A hoist A7 is arranged on the mounting plate 6, and the hoist A7 is drivingly connected to the hanging basket A8. The lifting drive assembly connects the sliding frame 5 and the limiting assembly. The lifting drive assembly includes a hanging rod 9, a sliding rod 10, and a hydraulic cylinder 12. The hanging rod 9 is connected to the sliding frame 5. The sliding rod 10 is inserted into the hanging rod 9 and slidably connected thereto. The two groups of sliding rods 10 are connected to the same cross plate 11. The body of the hydraulic cylinder 12 is connected to the hanging rod 9, and the push rod of the hydraulic cylinder 12 is connected to the cross plate 11. The limiting assembly is arranged between the hanging basket and the drive assembly 4. The limiting assembly is stuck on the bridge guardrail in the working state and moves along with the movement of the vehicle body 1. The limiting assembly includes a U-shaped frame 13, a support roller 14, a limiting roller 16, and a two-way module 17. The U-shaped frame 13 is rotatably connected to the cross plate 11. The support roller 14 is rotatably connected to the U-shaped frame 13. Two sliders 15 are symmetrically and slidably arranged on the U-shaped frame 13. The limiting roller 16 is rotatably connected to the slider 15. The rotation direction of the limiting roller 16 is perpendicular to the rotation direction of the support roller 14. The distance between the limiting roller 16 and the cross plate 11 is greater than the distance between the support roller 14 and the cross plate 11. The two-way module 17 is arranged on the U-shaped frame 13 and drives the two side sliders 15 to approach or move away from each other synchronously. The material transfer assembly is slidably connected to the support 3. The material transfer assembly transfers materials or tools to the hanging basket A8 in the working state.
[0025] In this embodiment, the position of the U-shaped frame 13 is appropriately adjusted so that it can just straddle the guardrail at a fixed point. Then, the staff carry tools and enter the hanging basket A8 on the vehicle body 1. The motor drives the support 3 to rotate until the U-shaped frame 13 is above the guardrail. Then, the hydraulic cylinder 12 presses down the U-shaped frame 13 and makes it stuck on the guardrail. At this time, the support roller 14 falls on the upper surface of the guardrail, and the two side limiting rollers 16 are respectively located on both sides of the guardrail, while the hanging basket A18 is located on the side of the guardrail away from the vehicle body 1. At this time, the two-way module 17 is started, and the two-way module 17 drives the two side sliders 15 to approach each other and makes the two side limiting rollers 16 respectively press against both sides of the guardrail. During the movement of the vehicle body 1, the support roller 14 and the limiting roller 16 slide freely along the guardrail, and the U-shaped frame 13 automatically rotates when the vehicle body 1 or the guardrail turns. Moreover, when the vehicle body 1 is in the state of moving away from or approaching the guardrail, the sliding frame 5 automatically slides. Since both the hanging basket A8 and the U-shaped frame 13 are connected to the sliding frame 5, the distance between the hanging basket A8 and the guardrail always remains unchanged, and it will not hit the guardrail.
[0026] Embodiment 2
[0027] As Figure 1 and Figure 2 shown, a bridge maintenance and inspection device proposed by the present utility model, compared with Embodiment 1, this embodiment also specifically discloses the structure of the material transfer assembly. The material transfer assembly includes a winch B18, a hanging basket B19, and a linear module 20. The linear module 20 is slidably connected to the bracket 3. The housing of the winch B18 is connected to the output end of the linear module 20, and a limiting rod parallel to the linear module 20 is provided on the bracket 3. The limiting rod penetrates through the housing of the winch B18 and slides with it. The hanging basket B19 is connected to the output end of the winch B18. The housing of the winch B18 is located between the two side sliding frames 5, and the housing of the winch B18 is located below the mounting plate 6.
[0028] In this embodiment, the materials or tools to be transferred are placed into the hanging basket B19. The winch B18 lifts the hanging basket B19, and then the linear module 20 drives the winch B18 and the hanging basket B19 to move close to the hanging basket A8. Then the hanging basket B19 lowers its height for easy access by the staff. This structure will never collide with the sliding frame 5 and the mounting plate 6 during the process of transferring materials.
