Abstract

The invention provides a jacking fixing system. The jacking fixing system comprises a hydraulic system, a plunger type hydraulic cylinder, a following mechanism and a gear transmission system. The plunger type hydraulic cylinder comprises a cylinder body, a crown sheet and a plunger. The following mechanism comprises a bevel gear nut and a screw. Inner threads are arranged inside the bevel gear nut, outer threads which are matched with the inner threads are arranged outside the screw, the screw is arranged inside the bevel gear nut, a release valve is arranged on the cylinder body, the crown sheet is arranged on the plunger, and the plunger, the bevel gear nut and the screw are all arranged inside the cylinder body. The hydraulic system drives the plunger to rise or fall, and the gear transmission system drives the bevel gear nut to rotate so as to enable the screw to rise or fall. The jacking fixing system can satisfy the demand of synchronous control of the plunger, and when the hydraulic system fails, can conduct top protection within a safe range to guarantee the safety of a component during jacking and falling processes.

Description

technical field [0001] The invention relates to the field of hoisting and installation, in particular to a jacking and roof protection system. Background technique [0002] In the field of hoisting and installation, hydraulic jacks are commonly used to lift heavy objects, and follow-up operations are carried out after lifting the heavy objects to a predetermined height. As a result, serious personal and equipment accidents are caused, and mechanical methods are often used to fix them, which is often called "roof protection". At present, measures such as screw support device support, special steel pier support, and wooden pier support are commonly used in construction. These methods need to occupy work space, affect subsequent operations, and are troublesome and time-consuming in implementation. Contents of the invention [0003] The purpose of the present invention is to provide a jacking and securing system to realize the integration of the jacking device and the securin...
