[0001] This application relates to the field of box girder hoisting technology, and in particular to a hoisting clamp for a box girder hoisting hole. Background Technology

[0002] In bridge construction, the hoisting of box girders is a critical process. Existing technology typically uses high-strength suspenders and high-strength bolts to fix the suspenders to the box girder to achieve the girder lifting operation.

[0003] During the box girder hoisting process, a steel plate needs to be placed below the hoisting hole to distribute the pressure generated by the hoisting rods or bolts, protect the surface of the box girder structure, and ensure the stability and safety of the hoisting operation.

[0004] The installation and removal of traditional steel plates mainly rely on manual operation. However, due to the large weight of the steel plates, there are significant safety hazards in the operation process. For example, personnel are prone to slipping and falling, causing injuries. In addition, the installation efficiency is low, and there is a lack of special tools to assist, which affects the construction progress and overall reliability.

In addition, the installation efficiency is low, and there is a lack of special tools to assist, which affects the construction progress and overall reliability.

[0024] Therefore, there is an urgent need for a hoisting clamp for the box girder hoisting hole to solve the above problems.

[0025] To address the aforementioned issues, this application provides a hoisting clamp for the box girder hoisting hole, which effectively prevents the hoisting steel plate from sliding downwards during installation, ensuring construction safety.

[0026] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0028] See Figure 1-5 A hoisting fixture for a box girder hoisting hole includes: a hoisting steel plate 1, a hoisting nut 2, and a steel plate clamp 3 fixed on the hoisting steel plate 1, all mounted on the hoisting bolt rod.

[0029] The steel plate clamp 3 includes: a clamping plate 301 and a limiting plate 302, wherein the clamping plate 301 is fixedly installed on the limiting plate 302; The front end of the clamping plate 301 is provided with a clamping groove 3011, the depth and width of which match the thread parameters of the lifting bolt rod, and is used to fix the clamping plate 301 in the thread of the lifting bolt rod.

[0030] The limiting plate 302 includes a limiting fixing plate 303 and limiting side plates 304 disposed on both sides of the limiting fixing plate 303. A first positioning hole 3031 is provided on the limiting fixing plate 303, and a second positioning hole 3041 is provided on the limiting side plate 304.

[0031] In this embodiment, by setting up a steel plate clamp 3, the clamping groove 3011 at the front end of the clamping plate 301 and the thread of the hoisting bolt can be precisely matched to achieve rapid fixation of the hoisting steel plate 1, effectively preventing the hoisting steel plate 1 from sliding downward during the installation process and ensuring construction safety. At the same time, by setting up a limiting plate 302, the installation of the steel plate clamp 3 can be guided, and the installation and alignment of the steel plate clamp 3 can be completed quickly, reducing the difficulty of operation and improving construction efficiency.

[0032] The front wall of the hoisting steel plate 1 is provided with a first fixing threaded hole 101 corresponding to the first positioning hole 3031, and the two side walls of the hoisting steel plate 1 are provided with a second fixing threaded hole 102 corresponding to the second positioning hole 3041. The limiting plate 302 is fixedly connected to the hoisting steel plate 1 by bolts.

[0033] In this embodiment, by using bolts to fix the first positioning hole 3031 and the first fixing threaded hole 101, and the two second positioning holes 3041 and the second fixing threaded hole 102 respectively, the steel plate clamp 3 and the hoisting steel plate 1 can be stably fixed, effectively preventing the steel plate clamp 3 from deflecting or twisting when under force, and ensuring the safety of hoisting construction.

[0034] In this embodiment, during installation, the lower pad steel plate is first installed, then the lower pad steel plate is fixed using the steel plate clamp 3, and then the lifting nut 2 is tightened; during disassembly, the lifting nut 2 is first loosened, then the steel plate clamp 3 is removed, and finally the lower pad steel plate is removed.

[0035] Specifically: a rubber pad is provided at the bottom of the card plate 301.

[0036] In this embodiment, the rubber pad at the bottom of the clamp 301 can play an anti-slip role, effectively preventing the clamp from loosening during hoisting and transportation.

[0037] Specifically: Steel plate lugs 103 are provided on both sides of the hoisting steel plate 1.

[0038] In this embodiment, the handles and lugs provided on both sides of the hoisting steel plate 1 provide gripping points for operators, making manual installation more convenient and labor-saving.

[0039] Specifically: The top of the lifting nut 2 is provided with a connecting flange 201.

[0040] In this embodiment, the flange at the top of the lifting nut 2 provides a larger contact area, which can further ensure the fixed stability of the lifting nut 2.

[0041] Specifically: the rear end of the card plate 301 is the card plate handle 305.

[0042] In this embodiment, the handle at the rear end of the clamp 301 provides construction workers with an additional point of leverage, making the installation and disassembly of the clamp more convenient and labor-saving.

[0043] The technical solution provided in this application has the following beneficial effects: This application, by setting up a steel plate clamp 3, achieves rapid fixation of the hoisted steel plate 1 through the precise engagement of the clamping groove 3011 at the front end of the clamping plate 301 with the thread of the hoisting bolt rod. This effectively prevents the hoisted steel plate 1 from sliding downwards during installation, ensuring construction safety. At the same time, by setting up a limiting plate 302, the installation of the steel plate clamp 3 can be guided, quickly completing the installation and alignment of the steel plate clamp 3, reducing operational difficulty and improving construction efficiency.

[0044] This application achieves stable fixation of the steel plate clamp 3 and the hoisting steel plate 1 by using bolts to fix the first positioning hole 3031 and the first fixing threaded hole 101, and the two second positioning holes 3041 and the second fixing threaded holes 102, thereby effectively preventing the steel plate clamp 3 from deflecting or twisting under stress and ensuring the safety of hoisting construction.
