Description

Technical Field

[0001] The utility model relates to the field of railway construction auxiliary tools, in particular to an auxiliary device for installing a high-speed railway box girder hanger. Background Art

[0002] The box girder hoist is a metal product with a large mass. In actual installation, at least one person is required to hold it up so that another person can install the bolts. The work intensity of the person responsible for holding it up is very high. Often, after installing several box girder hoists, the arm cannot be lifted. Considering how to solve the problem of box girder installation more efficiently, a high-speed railway box girder hoist installation auxiliary device is designed. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a high-speed railway box beam hanger installation auxiliary device which can reduce the labor intensity of workers and facilitate the installation of the box beam hanger.

[0004] The purpose of the utility model is achieved as follows: it includes a base frame, a plurality of universal self-locking wheels are provided at the bottom of the base frame, a load-bearing rod extending upward is fixed to the middle of the base frame, a U-shaped groove recessed downward is opened on the upper end surface of the load-bearing rod, and corresponding holes are provided on the two side walls of the U-shaped groove.

[0005] It also includes a top support rod, which has a plurality of radial pivot holes arranged in a front-to-rear manner at equal distances. The top support rod is placed in a U-shaped groove at the top of the load-bearing rod and is hinged to the load-bearing rod through stud bolts and nuts. That is, after the stud bolts are inserted into the holes on the two side walls of the U-shaped groove at the top of the load-bearing rod and a pivot hole on the top support rod, a nut is screwed on the stud bolts.

[0006] A handle is fixed to the rear end of the top support rod, and the handle is a curved hook handle.

[0007] A cross bar is fixed at the front end of the top support rod, and vertical bars extending forward are fixed at both ends of the cross bar. The upper surfaces of the front ends of the two vertical bars are correspondingly provided with disassembly grooves recessed downwards.

[0008] The utility model has the advantages that the top support rod and the load-bearing rod form a lever structure, and under the action of the lever, the box beam hanger can be driven upward, so that workers can install the box beam hanger more conveniently and achieve a labor-saving effect.

[0009] The load-bearing rod and the top support rod are hinged by a double-headed screw and a plurality of pivot holes are equidistantly provided on the top support rod. The double-headed screw here passes through the pivot hole and then nuts are screwed on both ends to realize the hinge of the top support rod. At the same time, in order to adjust the installation of box girder hangers of different heights, the top support rod here is detachable and the rotation position can be changed according to the position of the pivot hole, thereby achieving adjustment according to the quality of different models of box girder hangers and the installation height.

[0010] Fixing a hook handle at the rear end of the top support rod can provide workers with a better force application point during construction. At the same time, the design of the hook handle can facilitate workers to better drive the movement of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0012] Combine the following Figure 1 Further explain the utility model;

[0013] It comprises a base frame 1, a plurality of universal self-locking wheels 2 are arranged at the bottom of the base frame, a load-bearing rod 3 extending upward is fixed in the middle of the base frame, a U-shaped groove recessed downward is opened on the upper end surface of the load-bearing rod, and corresponding holes are arranged on the two side walls of the U-shaped groove;

[0014] It also includes a top support rod 4, which has a plurality of radial pivot holes 5 equidistantly arranged in a front-to-rear manner. The top support rod 4 is placed in a U-shaped groove at the top of the load-bearing rod and is hinged to the load-bearing rod through stud bolts and nuts. That is, after the stud bolts are inserted into the holes on the two side walls of the U-shaped groove at the top of the load-bearing rod and a pivot hole on the top support rod, a nut is screwed onto the stud bolts.

[0015] A handle 6 is fixed to the rear end of the top support rod, and the handle is a hook handle.

[0016] A cross bar 7 is fixed to the front end of the top support rod, and vertical bars 8 extending forward are fixed to both ends of the cross bar. The upper surfaces of the front ends of the two vertical bars are correspondingly provided with downwardly recessed disassembly grooves 9.

[0017] When in use, the connecting rod 10 is passed through the hole in the middle of the box beam hanger 11, and both ends of the connecting rod are exposed from the box beam hanger, and the connecting rods exposed from both ends of the box beam hanger are placed in the disassembly grooves at the front ends of the two vertical rods. Then the handle at the rear end of the top support rod is pressed down, and under the action of the lever, the box beam hanger can be driven to move upward, so that workers can greatly improve work efficiency and achieve labor-saving effects when installing the box beam hanger.

[0018] A number of radial pivot holes arranged front and back are equidistantly provided on the top support rod. By selecting different pivot holes, the installation of box beam hangers of different heights can be adapted, thereby achieving adjustment according to the quality and installation height of different types of box beam hangers, which is convenient for use.

[0019] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
