Description

Technical Field

[0002] As the voltage level and capacity of transformers continue to increase, the size of transformers will also increase accordingly, and the assembly of the transformer body will become relatively complicated and difficult, which brings many inconveniences to operators. In the assembly process of large transformers, assembly racks must be used to complete the assembly, and the installation and debugging of the body parts are completed through the forward and backward movement of the assembly rack and the up and down movement of the lifting platform.

[0003] However, in the assembly process of large transformers, there are usually small tooling for some small parts, which also rely on mobile overall assembly frames to complete the assembly work, occupying the crane and reducing work efficiency.

[0004] Therefore, it is necessary to propose an improvement to overcome the defects of the prior art. Summary of the invention

[0005] The utility model aims to solve the problems in the prior art and provides an assembly rack with an electric hoist on the top to solve the problem of small tooling assembly of small transformer parts when the large transformer assembly rack is working, so as to improve work efficiency.

[0006] The technical solution of the utility model is:

[0007] An assembly rack with an electric hoist on the top comprises an assembly rack, wherein the assembly racks on the left and right sides are both provided with lifting seats, a material discharge platform is installed between the two lifting seats, an upper cross beam is installed between the upper ends of the assembly racks on the left and right sides, a support beam is fixed on the upper cross beam, an electric hoist is installed on the support beam, and the electric hoist is arranged above the material discharge platform.

[0008] Through the above technical solution, during the transformer assembly operation, the electric hoist moves along the support beam and is used to hoist the transformer parts on the unloading platform during the small tooling assembly. It does not occupy the crane of the overall assembly frame, solves the assembly problem of small transformer parts, and improves work efficiency.

[0009] As a preferred technical solution, a reinforcing crossbeam is installed between the rear side surfaces of the left and right assembly frames to reinforce the overall vehicle frame.

[0011] As a preferred technical solution, a guide slide is provided at the bottom of the discharge platform, an adaptive guide slider is provided on the guide slide, and an electric cylinder is installed on the guide slider.

[0012] Among them, during the assembly process of large transformers, the transformer box is placed under the discharge platform, and transformer parts are stacked on the discharge platform for transformer assembly. In order to prevent the discharge platform from tilting or deforming due to pressure loss caused by excessive stacking of materials, a supporting electric cylinder is installed at the bottom of the discharge platform to solve the problem of tilting or deformation of the discharge platform.

[0013] As a preferred technical solution, guide wheels are provided on both sides of the lifting seat, and a lifting slide is provided on the assembly frame. The guide wheels are arranged in the lifting slide. When the lifting seat moves up and down, the guide wheels slide along the lifting slide, thereby ensuring the stability of the lifting seat when it moves up and down.

[0014] As a preferred technical solution, vertical screws are installed on the assembly frames on the left and right sides, a nut block matching the screw is rotatably installed on the lifting seat, a lifting motor is provided in the lifting seat, and the lifting motor drives the nut block to rotate, thereby driving the lifting seat to move up and down.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The utility model is provided with an assembly frame for an electric hoist on the top. By arranging the assembly frame, a lifting seat is arranged on the assembly frame, an upper crossbeam is installed on the assembly frame above the lifting seat, and the electric hoist is installed on the upper crossbeam, the purpose of not occupying the overall driving during the assembly of small parts of the transformer is achieved, which is convenient for operators to perform assembly operations and improves the overall work efficiency.
