[0002] The hoisting device with few hoisting points for anti-overturning reinforcement of single-column piers is a device used for reinforcing the structure of single-column piers. It can provide additional support, enhance the stability of the pier body, and prevent overturning. This device has a unique design and realizes the convenience of installation and disassembly through fewer hoisting points. The specific device design and operation process may vary depending on the manufacturer and specific circumstances. Generally speaking, this device will support the single-column pier from multiple directions through a special frame and support system to increase its anti-overturning ability. It is usually made of high-strength materials and can withstand the action of the pier body and external forces to ensure the stability of the structure.

[0003] However, the existing devices still have the following defects:

[0004] For the traditional installation construction of the steel capping beam of a single-column pier, it is necessary to implant steel bars and add lifting lugs at the bottom slab and web of the box girder, which will inevitably cause certain damage to the original prestressed structure of the box girder and easily cause damage inside the box girder. Therefore, we need to propose a hoisting device with few hoisting points for anti-overturning reinforcement of single-column piers. Content of the Utility Model

[0005] The purpose of the utility model is to provide a hoisting device with few hoisting points for anti-overturning reinforcement of single-column piers. By designing a bracket on the top of the pier, a distribution beam is arranged on the top of the bracket, and the bracket is set by post-anchoring. The device is characterized in that there is no need to implant steel bars and add hoisting points on the main beam, which can reduce the influence on the steel bar implantation of the prestressed bridge. The main hoisting point adopts a cross-shaped hoist, and the cross-shaped hoist is welded into a whole with section steel and is arranged on the top of the bridge pier. By setting hoisting points on the bridge pier and the main hoisting point of the cross-shaped hoist on the top of the pier, the hoisting of the steel capping beam can be realized, so as to solve the problems put forward in the above background technique.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-4 , the present invention provides a technical solution:

[0026] The rotating assembly 9 includes a motor 91 fixedly installed inside the bracket 7. A winding roller 92 is fixedly connected to the output end of the motor 91. A mounting bracket 93 is rotatably connected to the outside of the winding roller 92. A plurality of annularly distributed limiting holes 94 are opened inside the winding roller 92. A limiting rod 95 is slidably arranged inside the limiting hole 94. A fixing ring 96 is fixedly connected to the outside of the limiting rod 95. A spring 97 is sleeved on the outside of the limiting rod 95. A fixing pipe 98 is slidably connected to the outside of the limiting rod 95.

[0027] Exemplarily, the limiting rod 95 is pulled out, and the limiting rod 95 moves upward, disengaging from the limiting hole 94, releasing the limit on the winding roller 92. When the limiting rod 95 moves upward, the limiting rod 95 drives the fixing ring 96 to rise, and the fixing ring 96 squeezes the spring 97, causing the spring 97 to contract under force. The motor 91 is turned on, and the motor 91 drives the winding roller 92 to rotate. The winding roller 92 winds the connecting rope 4. The connecting rope 4 is driven through multiple pulleys, facilitating the lifting and lowering of the lifting plate 2 by the connecting rope 4. After the connecting rope 4 completes the lifting and lowering of the lifting plate 2, the limiting rod 95 is released. Under the elastic force of the spring 97, the fixing ring 96 drives the limiting rod 95 to move downward, and the limiting rod 95 is inserted into the inside of the limiting hole 94 to limit the winding roller 92.

[0028] The fixed pipe 98 is fixedly connected to the bracket 7, and the fixed pipe 98 is slidably connected to the fixing ring 96 and the limiting rod 95 respectively.

[0031] Exemplarily, the mounting bracket 93 installs the winding roller 92.

[0032] Two symmetrically distributed square wood plugs 12 are fixedly connected to the upper end of the cross-shaped hoist 10.

[0033] Exemplarily, the cross-shaped hoist 10 installs the square wood plugs 12.

[0036] A box girder 14 abuts against the upper end of the bearing pad stone 13, and the box girder 14 contacts the square wood plug 12.

[0037] Exemplarily, the bearing pad stone 13 and the square wood plug 12 support the box girder 14.

[0038] Working principle: When the present utility model is used, brackets 7 are designed at the top of the pier, a distribution beam 6 is arranged at the top of the brackets 7, and the brackets 7 are set by post-anchoring. The feature of the device is that there is no need to implant steel bars in the main beam to add lifting points, which can reduce the impact on the steel bar implantation of the prestressed bridge. The main lifting point uses the cross-shaped hoist 10. The cross-shaped hoist 10 is welded into an integral body with profiled steel and is arranged at the top of the bridge pier 1. Lifting points are set through the bridge pier 1 and the main lifting point of the cross-shaped hoist 10 at the top of the pier. Pulleys are arranged at the lifting points to facilitate the use of the connecting rope 4, and the hoisting of the steel cover beam can be realized.

[0039] Pull out the limit rod 95. The limit rod 95 moves upward, disengages from the limit hole 94, and releases the limit on the winding roller 92. When the limit rod 95 moves upward, the limit rod 95 drives the fixed ring 96 to rise. The fixed ring 96 squeezes the spring 97, and the spring 97 contracts under the force. The motor 91 is turned on, and the motor 91 drives the winding roller 92 to rotate. The winding roller 92 winds the connecting rope 4. The connecting rope 4 is driven through multiple pulleys, facilitating the connecting rope 4 to drive the lifting plate 2 to lift and lower. After the connecting rope 4 completes the lifting and lowering of the lifting plate 2, release the limit rod 95. Under the elastic force of the spring 97, the fixed ring 96 drives the limit rod 95 to move downward, and the limit rod 95 is inserted into the inside of the limit hole 94 to limit the winding roller 92.
