A road and bridge crane with double hooks that can stably lift larger construction materials

Abstract

The invention relates to a double-hook road and bridge crane being capable of stably hoisting large construction materials. The double-hook road and bridge crane includes a fixed cross beam, wherein a beam protecting shell fixedly sleeves an external wall of the fixed cross beam. Two fixed supporting columns are fixedly connected to the external wall of the lower end of the fixed cross beam. A rotating machine fixedly sleeves the external wall of the upper part of each fixed supporting column and includes a first fixing clamping trough, a rotating disk, a third three-phase asynchronous motor, a fixed connecting block, and a second fixing clamping trough. The first fixing clamping trough is fixedly embedded in the middle part of the inner wall of the rotating disk. The rotating disk is electrically connected to the middle part of the external wall of the third three-phase asynchronous motor. The fixed connecting block is fixedly connected to the outer wall of the lower end of the third three-phase asynchronous motor. The crane has stable performance when hoisting materials and is improved in work efficiency, and also can hoist materials in all directions and to all positions in a work site, thereby saving construction cost and achieving excellent work performance.

Description

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a double-hook road bridge crane that can stably lift relatively large construction materials, which can solve the problem that the existing road bridge cranes basically lift relatively heavy materials, although a single hook can lift the material However, when encountering relatively large materials, the stability of the single hook will become poor when lifting the material, and there are also problems with the working efficiency of the single hook during construction, which greatly lengthens the construction time. The cost of construction is increased and because the existing road and bridge cranes basically place the hook on the beam and use the sliding trolley to lift materials back and forth, but this design is extremely limited, and the crane can only lift materials in one direction , multiple road and bridge cranes are needed to complete the lifting of the materials required for construction, which greatly wastes the construction time and increases the construction cost. At the same time, the movement of the road and bridge cranes is relatively slow, which will waste A lot of time problems can realize the stable performance of the road and bridge crane when lifting materials, improve work efficiency, and at the same time can carry out all-round lifting of the construction site in all directions, saving construction costs and good work performance
