Jacking trolley for quickly assembling culvert sections and control method

Abstract

The invention discloses a jacking trolley for quickly assembling culvert sections and a control method. The jacking trolley comprises a trolley frame, a top sliding groove is formed in the upper surface of the trolley frame, and a bottom sliding groove is formed in the surface of the bottom of the trolley frame; a culvert section conveying crown block used for moving the culvert sections is arranged on the top sliding groove; hydraulic jacking devices used for jacking the trolley frame are arranged at the four ends of the bottom of the trolley frame; traveling crane auxiliary supporting legs for moving the trolley frame are arranged on the bottom sliding grooves; and an electric appliance operation control system is arranged in the trolley frame and used for controlling driving motors and the hydraulic jacking devices. A conventional traction pushing operation mode is changed, damage to finished products in the culvert section jacking construction process is effectively avoided while the operation efficiency and the operation safety are improved, and the purposes of saving labor and large hoisting traction equipment and being safe and efficient are achieved.

Description

technical field [0001] The invention relates to a rapid assembling trolley for concrete components, in particular to a jacking trolley and a control method for quickly assembling culverts. Background technique [0002] The prefabricated assembly technology of concrete box culverts can greatly increase the construction speed on site, reduce the environmental impact on the location of the box culvert and traffic interference, easily ensure the quality of the project, and reduce the life cycle cost of the box culvert. Its technical and economic advantages are increasingly being recognized by the bridge industry in various countries. Highly agree. [0003] In the assembly structure of concrete bridges using prefabricated assembly technology, there are a large number of box culvert components. Usually box culvert components are regular culvert blocks with large volume and high quality. In the construction and installation process, the measures of winch traction and slideway sli...

AI Technical Summary

Problems solved by technology

In the construction and installation process, the measures of winch traction and slideway sliding are usually adopted. This installation process requires multiple workers to work together inside the component, and it is difficult to adjust the lateral accuracy of the culvert during manual installation. When using a winch to pull the component The process is more likely to generate local stresses resulting in reduced component integrity and reduced life cycle

Therefore, the traditional construction technology obviously has the characteristics of insufficient installation accuracy, low construction efficiency, and large safety hazards.
