Description

Technical Field

[0001] The present invention relates to the technical field of construction equipment, and in particular to a universal device for assisting in dismantling a bracket. Background Art

[0002] In the bridge construction industry, truss structures are widely used due to their high strength, lightweight and good stability. However, during the demolition or reconstruction of bridges, the removal and transfer of trusses have always faced many challenges. In traditional methods, after the trusses are removed, the position of the load-bearing device needs to be manually adjusted so that it is located directly below the truss for smooth loading and transfer. This process is not only time-consuming and labor-intensive, but also prone to human operational errors that may cause the truss's center of gravity to be unstable, increasing safety hazards. At the same time, traditional load-bearing devices lack effective positioning and stabilization mechanisms when carrying trusses, making them prone to shaking or offsetting during transfer, and may even overturn due to unstable center of gravity.

[0003] In addition, when traditional devices are moved on complex steel frame structures, they are prone to deviation due to uneven surfaces or external forces, and lack effective deviation monitoring and automatic adjustment functions. Once the deviation occurs, manual intervention and adjustment are required, which reduces work efficiency and may delay the timing and cause accidents. Moreover, traditional devices lack the function of real-time monitoring of center of gravity changes during the transfer process, and cannot detect and adjust the center of gravity deviation in time, which increases the risk. Finally, traditional devices can usually only adapt to specific scenarios or truss structures, lack versatility and adaptability, and are difficult to meet the diverse needs of the bridge construction industry.

[0004] Therefore, the existing technology has many problems in the transfer process after the truss is dismantled. There is an urgent need for a device that can automatically position, stably load, and monitor the offset and center of gravity changes in real time to improve construction efficiency and safety.

The first box is installed in the outer wall of the shell, and a first trigger signaler is installed at the bottom of each first box. The first trigger signaler is electrically connected to the terminal.

[0009] Preferably, the diameter of the first full gear is greater than the diameter of the second full gear, and the second full gear, the gear rod and the first housing are all symmetrically arranged about the center line of the housing.

[0028] Working principle: According to Figure 1As shown, after the truss is dismantled, it needs to be safely moved to the designated location. First, the truss is steadily lifted up using a jack to separate it from the supporting structure. Then, the device is pushed under the truss. As the jack slowly lowers the truss, due to the generally inverted "concave" structure under the truss, its two ends will first contact the inclined surface of the guide plate 302. As the truss is lowered, the guide plate 302 is squeezed, pushing the housing 1 to automatically move to the middle position directly below the truss in conjunction with the moving roller 2. This process not only makes the subsequent load-bearing force on the truss more stable, but also effectively avoids the tedious operation of manually adjusting the position of the device, significantly improving work efficiency.

[0029] As the jack continues to lower, the lower ends of the truss will contact the top sides of the shell 1 and the rough roller 402; at this time, the device begins to bear the weight of the truss, providing stable support for subsequent transfer operations;

[0030] Since the transfer of the truss after dismantling is usually carried out on a steel frame rather than a flat concrete surface of the bridge, it needs to be pulled by a fall chain; during the pulling process, the operator should ensure that the front and rear fall chains are tightened and loosened synchronously to make the truss move smoothly and slowly; if during the movement, the device and the truss carried on it deviate on the steel frame, the roller drum 505 on the shell 1 close to the offset side will first break away from the upper end surface contact of the steel frame; under the action of the spring member 506, the roller drum 505 will drive the vertical rod 504 to move downward; the second movable plate 503 connected to the upper end of the vertical rod 504 moves downward in the second box body 502 until it contacts the second trigger signal device 507; at this time, the second trigger signal device 507 will transmit a signal to the terminal to remind the staff who controls the fall chain for pulling to stop pulling and make adjustments in time to correct the deviation and ensure the stable movement of the device and the truss;

[0031] During the traction movement, if the device and the truss carried on it are affected by factors such as pauses or speed changes, and are about to be offset and misaligned, resulting in an unstable center of gravity, the contact area between the lower end of the truss and the top of the shell 1 will move and be misaligned; at this time, the rough roller 402 that is fitted and connected to the lower end of the truss will rotate accordingly; the rough roller 402 drives the first full gear 403 to rotate, and the first full gear 403 drives the meshing second full gear 404 to rotate; since the diameter of the first full gear 403 is much larger than the diameter of the second full gear 404, the second full gear 404 will rotate multiple circles, thereby driving the gear rod 405 to push the first movable plate 406 to move into the first box 407; when the first movable plate 406 contacts the first trigger signal device 408 in the first box 407, the first trigger signal device 408 will transmit a signal to the terminal, reminding the staff who controls the fall chain for traction to make timely adjustments to ensure the stable movement of the device and the truss. This is the working principle of the universal device for assisting in the removal of the bracket.
