Jacking device for roller shaft

Abstract

The invention relates to a jacking device for a roller shaft. The jacking device for the roller shaft comprises a bottom plate, stand columns fixed on the bottom plate, and a supporting table connected to the tops of the stand columns, a servo motor is installed on the supporting table, a driving shaft of the servo motor is connected with a long worm, and three lifting mechanisms are uniformly distributed on the long worm in the axis direction of the long worm; each lifting mechanism comprises two worm wheels which are distributed in a front-back mode and are meshed with the long worm, the worm wheels are rotationally connected with mounting seats fixed on the supporting table, and avoiding vertical holes which are distributed coaxial with the worm wheels are formed in the mounting seats;and the middles of the worm whees are in threaded connection with long screw rods penetrating through the avoiding vertical holes, guide rods which are fixed on the bottom plate and limit the rotationof the bottom plate are arranged at the bottoms of the long screw rods in a sliding fit mode, and supporting blocks are fixed at the tops of the long screw rods. According to the jacking device for the roller shaft, when the roller shaft is lifted, the higher stability is achieved, the mounting precision relative to a clamping table is high, so that the use safety is greatly improved, and the whole device has the advantages of being simple to operate, convenient to use and capable of moving.

Description

technical field [0001] The invention relates to the technical field of lifting machinery, in particular to a jacking device for a roller shaft. Background technique [0002] Roller shaft, generally refers to the general name of the cylindrical parts that can roll on the machine. Generally, the roller shaft is large and heavy, and it is difficult to move and lift. It needs to be installed with the clamping table after being lifted by driving or lifting equipment. However, most of the driving or hoisting equipment is a steel cable structure, which has poor stability during hoisting, low installation accuracy with the clamping table, and the roller shaft is easy to shake during the lifting and lowering process, which is highly dangerous and has great potential safety hazards, which is not conducive to Roller jacking. Contents of the invention [0003] In order to avoid and solve the above technical problems, the present invention proposes a jacking device for a roller. [0...
