Device capable of adjusting large shaft turning jack

Abstract

The invention discloses a device capable of adjusting a large shaft turning jack. The device comprises an arc-shaped bracket, a spherical adjusting bolt, an adjusting bolt, a rectangular supporting frame, a jack, a rapid pressure rod handle, a magnetic base, a V-shaped groove, a magnetic switch, a reinforcing rib, a fine adjustment pressure rod handle, an oil cylinder, a rotating baffle, an oil drain valve, a large cylinder, a large piston, a supporting column, a one-way valve, a middle piston, a middle cylinder, a small piston and a small cylinder. The device is mainly used for auxiliary equipment of large shafts, and the technical principle of machinery and the jack is adopted, so that the technical problem of large shaft turning clamping is solved; and the jack in the device is operated through double pressing rods, the rapid pressure rod and the fine adjustment pressure rod are operated in an alternative mode, the arc-shaped bracket is arranged above the device and used for supporting a large shaft, and the adjusting bolt on the arc-shaped bracket can be adjusted according to the diameter of the large shaft. The height of the device can be rapidly and accurately adjusted according to requirements, shafts with different diameters can be moved, and the device is convenient, rapid, safe and reliable.

Description

technical field [0001] The invention relates to the clamping technology of auxiliary equipment for processing large axle cars, in particular to an adjustable jack device for processing large axle cars. Background technique [0002] At present, for some production workshops that need to move larger and heavier shafts, the operation process of crane hoisting is generally used, which doubles the work intensity for operators, and is prone to excessive fatigue accidents, which is not conducive to safety. Assure. For example, the large-scale shafts in workshop processing generally have a length of 3m-5m, a diameter of φ250mm-φ300mm, and a weight of 1-3 tons. Difficult to adjust, labor-intensive, time-consuming, and even accidents that cause people to be smashed and injured. [0003] Current jacks are stationary and difficult to move during use. There are two types of jacks: mechanical and hydraulic. The application range of hydraulic jacks is more than that of mechanical jacks...

AI Technical Summary

Problems solved by technology

Therefore, in order to solve these problems, scientific research units and enterprise scientific and technological personnel are constantly exploring and researching, and using modern science and technology, hope to manufacture a jack device that can quickly adjust the large axle car processing. Although some progress has been made in technology, in practice There are still technical problems that have not been overcome in the application
