Technical Field

[0001] This utility model relates to the field of bridge construction technology, specifically to a hanger device for bridge construction. Background Technology

[0002] In bridge construction and other large-scale engineering projects, the hoisting of long steel strips such as H-beams and square steel is one of the key processes.

[0003] The existing gantry system involves personnel pulling the chains at the bottom of the gantry to both ends of the bundled H-beams. The bundled H-beams are then installed using hooks at the ends of the chains. Finally, the gantry is lifted by the hoisting device, which facilitates the transfer or transport of the bundled H-beams.

[0004] Although the above equipment can lift bundles of H-beams, the varying lengths of the bundles necessitate constant chain replacements to adjust the chain length and accommodate different bundles of H-beams. This process requires continuous chain disassembly, increasing the workload for the personnel. Utility Model Content

[0005] In view of this, the present invention provides a gantry device for bridge construction. The present invention allows the rope to be extended or retracted, thereby adapting to the hoisting work of steel of different lengths.

[0006] To solve the above-mentioned technical problems, this utility model provides a gantry device for bridge construction, including a gantry body, a support shell at the bottom of the gantry body, and a winding assembly inside the support shell. The winding assembly includes a winding roller inside the support shell, with two sets of ropes wound on the winding roller. A rectangular groove is provided at the bottom of the support shell, and hooks are provided at the ends of the two sets of ropes. According to the length of the H-beam or square steel, the operator rotates the winding roller in the winding assembly. When the winding roller rotates, the two sets of ropes originally wound on it will gradually loosen with the rotation, realizing the release of the ropes and extending the length of the ropes to reach the two ends of the bundled H-beams. The operator pulls the extended two sets of ropes to the two ends of the bundled H-beams respectively, and uses the hooks provided at the ends of the ropes to firmly hook them onto the H-beams, establishing a connection between the ropes and the H-beams, thus adapting to the hoisting work of steel of different lengths.

[0007] The winding assembly also includes a worm gear disposed on one end of the winding roller, and a worm is disposed inside the support housing, with the worm gear meshing with the worm; that is, the worm and the worm gear mesh, which has a self-locking function.

[0008] The winding assembly also includes a drive button located on the side of the support housing, with the side of the drive button connected to one end of the worm gear; that is, the drive button facilitates the driving of the worm gear.

[0009] The winding assembly also includes two limiting discs mounted on the winding roller. The sides of the two limiting discs are located at one end of each of the two sets of ropes. A separator disc is mounted on the winding roller, and the separator disc is located at the center of the two limiting discs. The separator disc can thus prevent the ropes from getting tangled.

[0010] Two support crossbars are provided on the bottom of the hanger body, and the side ends of the two support crossbars are connected to the two ends of the support shell; that is, the support crossbars provide support for the support shell.

[0011] Both support crossbars are equipped with several hanging holes; this facilitates the subsequent installation and use of multiple hooks and chains to hoist different objects.

[0012] The main body of the hanger is provided with two lifting holes, each containing a connecting ring, and each connecting ring containing a lifting ring; that is, a lifting ring, so as to facilitate the use of lifting devices to lift the whole unit.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects: 1. First, the operator rotates the drive button, which allows the worm gear to rotate clockwise or counterclockwise. This causes the worm gear to rotate, which in turn drives the winding roller to rotate, facilitating the winding and unwinding of the rope and adapting to hoisting work with steel of different lengths.

[0014] 2. Several hanging holes on the support bar facilitate the subsequent installation and use of multiple hooks and chains to hoist different objects. Attached Figure Description
