Lower die polishing device and polishing method

Abstract

The invention relates to a lower die polishing device and a polishing method. The lower die polishing device comprises a truss, a longitudinal beam moving mechanism, a bidirectional moving mechanism, a main polishing head mechanism and an auxiliary polishing head mechanism. The longitudinal beam moving mechanism is installed on the truss in a sliding mode, the bidirectional moving mechanism is installed on the longitudinal beam moving mechanism in a sliding mode, the longitudinal beam moving mechanism moves in the first direction of the truss, the bidirectional moving mechanism moves in the second direction and the third direction of the truss, and every two of the first direction, the second direction and the third direction are perpendicular to each other; the main polishing head mechanism is connected with the bidirectional moving mechanism; the auxiliary grinding head mechanisms are oppositely installed on the longitudinal beam moving mechanisms on the two sides of the main grinding head mechanism. The main polishing head mechanism and the auxiliary polishing head mechanism carry out mechanical polishing operation on the lower die, the number of workers needing to participate in polishing operation is reduced, the construction safety is improved, the polishing efficiency of the lower die is improved through the main polishing head mechanism and the auxiliary polishing head mechanism, then the production efficiency of the bent cap is improved, and the requirement of factory type operation is met.

Description

technical field [0001] The invention relates to the technical field of cover beam construction, in particular to a lower mold grinding device and a grinding method. Background technique [0002] The cap beam refers to the beam set on the top of the bent pile pier in order to support, distribute and transmit the load of the superstructure, also known as the cap beam. [0003] Reinforced concrete or less-reinforced concrete beams are set on piers (platforms) or row piles. The main function is to support the superstructure of the bridge and transfer all loads to the substructure. Some bridge piles are directly connected to the cover beam, and some bridge piles are connected to the column and then connected to the cover beam. [0004] Prefabricated cap beams have been developed rapidly and widely used at home and abroad due to their large section torsional strength and bending strength, simple structure, convenient construction, low cost, and time-saving construction.

AI Technical Summary

Problems solved by technology

[0008] There is no corresponding lower mold grinding device on the existing cover beam production line. Therefore, it is necessary to manually operate the grinding of the lower mold, and the grinding efficiency is limited to a certain extent, which in turn has a certain impact on the production efficiency of the cover beam, which cannot meet the requirements. factory-style requirements
