Description

Technical Field

[0001] This utility model relates to the field of reduction gearbox technology, specifically a lifting fixture for a reduction gearbox gear package. Background Technology

[0002] A gear reducer works by connecting a prime mover to a reducer, which in turn connects to a working machine. It is a power transmission device. The gearbox is an important component of the reducer. When repairing a reducer, the gearbox needs to be removed and then hoisted by an overhead crane.

[0003] Existing lifting fixtures for gearboxes mainly rely on wire rope clamps to temporarily create wire hooks for lifting. However, creating these wire hooks is complex and cannot maintain the stability of the gearbox. Therefore, a new type of lifting fixture for gearboxes is needed. Utility Model Content

[0004] The purpose of this utility model is to provide a hoisting fixture for a gearbox gear set, which solves the problems mentioned in the background art.

[0005] This application provides a gearbox gear assembly lifting fixture, including a gear assembly body. A support frame is fixedly sleeved on the outside of the gear assembly body. A rod is transversely inserted through the support frame. A limit block and a locking nut are threadedly connected to the rod. The locking nut is located on the side of the limit block near the support frame. A slider is slidably connected to the rod. The slider is engaged between the limit block and the locking nut. A fixing frame is fixedly connected to the top of the slider. A lifting ring is fixedly connected to the top of the fixing frame.

[0006] In use, first insert the rod into the support frame, then lock the rod in place with the locking nut, then put the slider on the outside of the rod and use the fixing frame to complete the installation of the lifting ring. Then, use the limit block to limit the slider between the locking nut and the limit block. Pass the sling through the lifting ring and use the overhead crane to complete the hoisting of the equipment. It has good stability and the hoisting structure is easy to assemble and disassemble.

[0007] Optionally, the support frame is provided with a socket adapted to the insertion rod.

[0008] The above technical solution facilitates the installation of the insertion rod.

[0009] Optionally, two insertion rods are provided, and the two insertion rods are arranged symmetrically front to back.

[0010] By adopting the above technical solution, the stability of the mounting bracket can be improved.

[0011] Optionally, two fixing frames are provided, and the two fixing frames are arranged symmetrically on the left and right.

[0012] By adopting the above technical solution, it is beneficial to install two lifting rings. When the two lifting rings are installed simultaneously with the lifting straps and used in conjunction with the overhead crane for hoisting, the stability of the gear package body hoisting can be improved.

[0013] Optionally, both the insertion rod and the fixing bracket are made of steel.

[0014] By adopting the above technical solutions, the strength of the insertion rod and the fixing frame can be improved, making them less prone to deformation and damage.

[0015] Optionally, the insertion rod and the gear package body are spaced 3 cm apart.

[0016] By adopting the above technical solution, it is beneficial to quickly disassemble and assemble the limit block, slider, and locking nut.

[0017] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0018] The technical solution of this application first inserts the plug rod into the support frame, then locks and fixes the plug rod with the locking nut, then puts the slider on the outside of the plug rod, and completes the installation of the lifting ring with the fixing frame. Then, the slider is limited between the locking nut and the limiting block by the limiting block. Through the cooperation of the above structures, the gear pack body can be stably lifted and the disassembly and assembly are convenient. Attached Figure Description
