Modular height adjusting device, support and intelligent adjusting system

Abstract

The modular height adjusting device and support comprises a support body, a height adjusting mechanism is arranged above or below the support body, a connecting part used for being connected with a module power device is arranged on the height adjusting mechanism, and the module power device provides adjusting power for the height adjusting mechanism. The driving device is connected with a controller for controlling the action of the driving device. According to the scheme, modular design of heightening power is achieved, mounting and dismounting are convenient, and meanwhile intelligent and accurate heightening is achieved.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to a modular height adjustment device, a support and an intelligent adjustment system. Background technique [0002] The height adjustment device of the bridge is an important structural component connecting the upper structure and the lower structure of the bridge. It can reliably transmit the reaction force and deformation (displacement and rotation angle) of the upper structure of the bridge to the lower structure of the bridge. The basin height adjustment device has a bearing capacity The advantages of large, large displacement, flexible rotation angle, consistent rotation performance in all directions, and wide application range of temperature are widely used in municipal, highway, and railway bridges. During the construction and operation of bridges, in order to ensure the safety of bridges, it is necessary to Keep abreast of the stress status of the height adjustme...

Problems solved by technology

Once the height adjustment device is empty, the durability of the height adjustment device itself will be affected, the number of design support points will be reduced, and the load limit of the adjacent height adjustment device will be aggravated, and it will be in an overloaded state, shortening its normal service life, thus changing the force mode of the height adjustment device , multi-point stress displacement and single-point stress induce structural damage, threaten the safety and health of the height adjustment device structure, and are prone to disasters such as falling beams

[0003] At present, the height adjustment of the height adjustment device basically adopts the height adjustment method of the backing plate and the spiral height adjustment method. It is necessary to lift the beam body to realize the height adjustment of the height adjustment device. The height adjustment method and process are complicated, the construction is troublesome, and the cost is high; the filling height adjustment Although the method does not need to lift the beam body, before the height adjustment, it can only be determined according to the theoretical bearing force of the height adjustment device or through manual monitoring of the force of the height adjustment device to determine the height adjustment amount. The period for determining the height adjustment amount is long , The accuracy rate is low, and the force change of each height adjustment device cannot be determined during the height adjustment process and after the height adjustment, which brings hidden dangers to the safety of the structure

[0004] Moreover, the currently commonly used jacking method is composed of an electric motor, a high-pressure hydraulic pump, a fuel tank, an operation control system, a jack, oil pipes, and a flow divider. The traffic on the bridge needs to be closed, the social impact is great, the construction progress is slow, and the cost is high. The existing height-adjusting support cannot realize real-time and accurate intelligent adjustment of the support, and the height-adjusting power system cannot realize modular installation
