Description

Technical Field

[0001] The utility model belongs to the technical field of bridge construction, and more specifically, particularly relates to an air-side operation platform for a bridge anti-collision wall. Background Art

[0002] The operating platform is a work platform set up to ensure the smooth progress of each construction process. It is widely used in housing construction, bridge construction and other projects. Commonly used operating platforms include fixed, mobile and lifting types. At present, the suspended operating platform is becoming more and more popular in the industry because it is easy and fast to build, flexible in combination, can be built in various specifications according to different actual needs, safe and stable, simple and convenient, easy to store and transport, small in space, materials can use on-site resources, and the components are short and easy to operate.

[0003] Based on the above, the inventors have discovered the following problems: the operating platform is usually located at the bottom of the bridge and is usually fixed with moving wheels, which is convenient for moving to the next location after the crash barrier at one location is repaired. However, there is generally no limiting device for limiting the positioning, which causes shaking when construction workers stand on the operating platform during work, which is quite dangerous and affects the construction. In order to increase safety, heavy objects also need to be placed on the top of the operating platform located at the bridge, which requires manual handling and increases the workload.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an aerial operation platform for bridge crash wall is provided, in order to achieve a more practical purpose. Utility Model Content

[0029] Among them, the threaded sleeve 12 and the first threaded rod 11 are threadedly connected, the bottom of the guide rail 3 is arranged in an inclined shape, and a slope 82 is arranged at the bottom of the moving block 8. The moving block 8 is slidably connected with the guide rail 3, so that when the moving block 8 slides downward inside the guide rail 3, it can slide from the inside of the guide rail 3, and the first threaded rod 11 is driven to rotate by the servo motor 10. The first threaded rod 11 rotates inside the threaded sleeve 12, so that the distance between the two ends becomes longer, and the moving block 8 is pushed out from the inside of the guide rail 3.

[0030] Among them, second moving wheels 83 are fixed at the four corners of the bottom of the moving block 8, and a protrusion 81 is fixed at the bottom of the end of the moving block 8 away from the base frame 1. When the moving block 8 slides out of the guide rail 3, the protrusion 81 will first touch the bridge deck, and the friction between the protrusion 81 and the bridge deck limits the first moving wheel 2. The second moving wheel 83 is set to enable the protrusion 81 to move better inside the guide rail 3.

[0031] Among them, a third connecting plate 20 is fixed in the middle of one side of the second support rod 5, and second pulleys 21 are fixed at both ends of the third connecting plate 20 close to the base frame 1. When in use, the second pulley 21 is fitted against the outside of the bridge crash barrier, and when moving, the second pulley 21 slides on the outside of the bridge crash barrier.

[0032] Among them, a second connecting plate 13 is fixed in the middle of the first support rod 4 and the middle of the top of the second support rod 5, a second threaded rod 18 is threadedly connected through the middle of the second connecting plate 13, a handle 19 is fixed at one end of the second threaded rod 18, and the other end of the second threaded rod 18 is rotatably connected to a movable plate 16.

[0033] Among them, a first pulley 17 is fixed on one side of the movable plate 16, and a plurality of first pulleys 17 are provided, and the plurality of first pulleys 17 are arranged horizontally and equidistantly. After the second pulley 21 is fitted with the outside of the bridge crash barrier, the positions of the first pulley 17 in the middle of the first support rod 4 and the first pulley 17 in the middle of the second support rod 5 are adjusted, and the second threaded rod 18 is driven to rotate by turning the handle 19.

[0034] Among them, the first telescopic rods 15 are fixed to both ends of the other side of the movable plate 16, and the first sleeve rods 14 are fixed to both ends of the second connecting plate 13 close to the movable plate 16.

Through the cooperation of the first telescopic rods 15 and the first sleeve rods 14, the movable plate 16 will not rotate with the rotation of the second threaded rod 18, so that the positions of the movable plate 16 and the first pulley are changed, and the two groups of first pulleys 17 are respectively fitted with the inner side and the top of the anti-collision wall, so that the device is more stable when moving.

[0035] The specific usage and function of this embodiment are as follows:

[0036] In the utility model, firstly, the second pulley 21 is fitted with the outside of the bridge anti-collision wall when in use, and the second pulley 21 slides on the outside of the bridge anti-collision wall when moving, and the positions of the first pulley 17 in the middle of the first support rod 4 and the first pulley 17 in the middle of the second support rod 5 are adjusted, and the second threaded rod 18 is driven to rotate by turning the handle 19. Through the cooperation of the first telescopic rod 15 and the first sleeve rod 14, the movable plate 16 will not rotate together with the rotation of the second threaded rod 18, so that the positions of the movable plate 16 and the first pulley are changed, and the two groups of first pulleys 17 are respectively fitted with the inner side and the top of the anti-collision wall, so that the device is more stable when moving. After the second pulley 21 and the first pulley 17 are adjusted, the worker enters the operating table 6 and starts the servo motor 10. The servo motor 10 drives the first threaded rod 11 to rotate. The first threaded rod 11 rotates inside the threaded sleeve rod 12, so that the distance between the two ends becomes longer, and the moving block 8 is pushed out from the inside of the guide rail 3. The second moving wheel 83 is set so that the protrusion 81 can move better inside the guide rail 3. When the moving block 8 slides out of the guide rail 3, the protrusion 81 will touch the bridge deck first. The friction between the protrusion 81 and the bridge deck limits the first moving wheel 2. At the same time, through the lever principle, the protrusion 81 is farther away from the second support rod 5 to provide greater supporting force.
