Detachable bridge combined swivel support

Abstract

The invention discloses a detachable bridge combined swivel support which comprises a base, two connecting blocks are connected to the upper surface of the base in a penetrating mode, a rotating shaftis fixedly connected to the upper surface of each connecting block, a pulley is rotatably connected to the upper surface of each connecting block, and a supporting plate is connected to the upper surface of the base in a penetrating mode; a computer is fixedly connected with one side of the base; a linear motor, the pulley and the connecting blocks are arranged, the linear motor is controlled through buttons, telescopic rods are controlled to extend , the height of the connecting blocks is increased, after the connecting blocks reach the height flush with a tray, the positions of the telescopic rods are fixed, a sliding rod is pulled, and a circular supporting plate is taken out of the lower surface of a pier; the telescopic rods are used for sharing the gravity borne by the tray, meanwhile, the sliding rod connected between a connecting bottom plate and a supporting bottom in a sliding mode is used, the device can be easily taken out of the pier, and any part of the device cannot deform due to excessive stress.

Description

technical field [0001] The invention belongs to the technical field of bridge supports, in particular to a detachable bridge combined swivel support. Background technique [0002] With the development of my country's society and economy, and the start of a new round of infrastructure construction, it is necessary to build more bridges across existing roads, railways, rivers, ditches, etc. The advantages of small impact and low safety risk have been widely used. The bridge swivel method can avoid the impact on the nearby transportation lines to the greatest extent, and it can also overcome the difficulties of erecting long-span bridges on rivers with high mountains and canyons, deep water and fast currents, or frequent ship navigation, especially in the construction of cities in heavy traffic areas. For flyover bridges and railway flyover bridges, the advantages of the bridge swivel method are more obvious. In recent years, bridge swivel construction technology has become mo...

AI Technical Summary

Problems solved by technology

[0003] 1. The existing bridge support device is inconvenient to take out after supporting the bridge, and the base of the device is easily deformed in the case of forced removal

[0004] 2. In addition, in the existing bridge support device, the contact between the tray and the bridge cannot be buffered. As the use time increases, the supporting capacity of the device will decrease

[0005] 3. Finally, most of the existing bridge support devices use bolts to fix the internal structure. During the construction process, the violent collision between the device and the bridge will easily cause the internal structure of the device to shift
