Socket and spigot type prefabricated pier automatic positioning device and operation method

Abstract

The invention relates to the technical field of concrete bridge prefabricated assembly, in particular to a socket and spigot type prefabricated pier automatic positioning device and an operation method. The device comprises the components of a concrete carrier which has a certain thickness, and a bell and spigot is formed in the surface for inserting the prefabricated pier; multiple positioning mechanisms which are arranged around the prefabricated pier and are matched with one another to clamp the prefabricated pier to adjust the position of the prefabricated pier in the bell and spigot; a lifting mechanism which is used for supporting the positioning mechanism and adjusting the position of the positioning mechanism in the vertical direction; an electric control mechanism which is in circuit connection with the positioning mechanism; the positioning mechanism comprises a fixing box, a fixing rod, a wheel strip and a gear; the fixed box is connected with the lifting mechanism; the wheel strips penetrate through the fixing box and abut against the prefabricated pier. And a plurality of tooth grooves are distributed on the wheel strips. Aiming at the defects in the prior art, the invention provides the socket and spigot type prefabricated pier automatic positioning device and the operation method, and the practicability is improved.

Description

technical field [0001] The invention relates to the technical field of prefabricated concrete bridges, in particular to an automatic positioning device and an operation method for socket-type prefabricated bridge piers. Background technique [0002] The prefabricated assembly technology of concrete bridges can speed up on-site construction, greatly reduce the impact on the bridge environment and traffic interference, easily ensure the quality of the project, and reduce the cost of the bridge life cycle. Its technical and economic advantages are increasingly recognized by the bridge industry in various countries . With the improvement of my country's industrialization level and the rise of labor costs, prefabrication and assembly technology is an inevitable trend in the future development of the construction industry.

AI Technical Summary

Problems solved by technology

[0003] In the process of placing large-scale prefabricated bridge piers, in order to ensure that the bridge piers are evenly stressed, the accuracy of placement is relatively high. However, the current positioning of traditional prefabricated bridge piers is to use a large crane and cooperate with several workers to place them. This process is expensive. , the accuracy is not enough, and it is easy to cause accidental injury
