Pile grinding device for concrete pipe piles

Abstract

The invention discloses a pile grinding device for concrete pipe piles. The device comprises a first speed adjusting motor, a second motor, a grinder, a dovetail groove, a chassis, a driven support roller, a screw tilting fillet, a support roller bearing tilting fillet, a grinding disc, a screw hand wheel, a positioning bearing, a driving support roller and a lead screw. The first speed adjustingmotor is connected with the driving support roller through a chain; the second motor is connected with the grinder through a triangular belt; the grinder is mounted in the dovetail groove; the grinding disc of the grinder extends out of the dovetail groove; the screw hand wheel is fixedly connected with the lead screw; the screw tilting fillet supports the lead screw; the chassis is mounted on thepositioning bearing; the driven support roller and the driving support roller are arranged on the chassis; and the driven support roller is arranged on the support roller bearing tilting fillet. Compared with the prior art, the grinding disc of the pile grinding device for the concrete pipe piles and pipe sections are rotated at the same time; and the whole pipe wall end surfaces are uniformly contacted with the grinding disc, so that the flatness of the pipe wall end surfaces is easy to meet the standard requirement.

Description

technical field [0001] The present application relates to the field of construction machinery, and more particularly, to a pile grinding device for concrete pipe piles. Background technique [0002] PHC pipe piles are prestressed high-strength concrete pipe piles. It adopts the pre-tensioned prestressed centrifugal forming process, and after 10 atmospheric pressure (about 1.0Mpa) and steam curing at about 180°C, a hollow cylindrical concrete prefabricated component is made. The standard section length is 10m, and the diameter is from 300mm ~ 800mm, concrete strength grade ≥ C80. In recent years, the PHC pipe pile industry has developed rapidly. At present, domestic PHC pipe piles are mainly used in the field of real estate construction. As the country increases the intensity of construction of affordable housing, the application proportion in the field of real estate accounts for about 80% in 2012; the application proportion in the field of road construction is about 10%; ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the pile grinding machine is used for the lower casing, and the flatness of the end surface of the PHC pipe wall is the key point of the project quality. The uneven contact makes it difficult for the flatness of the end surface of the pipe wall to meet the standard requirements, which seriously affects the progress and quality of the project
