Tubular pile concrete injection device

Abstract

The invention provides a tubular pile concrete injection device. The tubular pile concrete injection device comprises first supporting pieces, a lifting assembly, a second supporting piece and a fixed supporting frame which are sequentially distributed along the same straight line, wherein a mold is placed at the upper ends of the multiple first supporting pieces, a conveying pipe is placed at the upper ends of the second supporting piece and the fixed supporting frame, the fixed supporting frame is fixed to the ground, the first supporting pieces and the second supporting piece can linearly move along the distribution straight line of the first supporting pieces and the second supporting piece, the lifting assembly comprises side plates fixed to the two sides of the ground, a top plate is fixed to the tops of the side plates, a connecting arm is fixed to the lower end of the top plate, and an electromagnet is fixed to the lower end of the connecting arm. According to the concrete injection device provided by the invention, concrete is evenly injected into the mold through the conveying pipe by moving the mold, upward magnetic force is provided for the conveying pipe through the electromagnet, the conveying pipe is kept horizontal during working, and the problem that the conveying pipe is bent downwards due to no support and accordingly deforms and even fractures is avoided.

Description

technical field [0001] The invention relates to the technical field of concrete pipe piles, in particular to a concrete injection device for pipe piles. Background technique [0002] Concrete pipe piles are prestressed pipe piles that are formed by injecting concrete into a cylindrical mold and formed by centrifugal action. At present, when the factory produces concrete pipe piles, the steel skeleton of the pipe piles is first put into the cylindrical hollow mold, and then injected into the mold Concrete is injected inside. In large-scale pipe pile enterprises, concrete is usually transported by pipeline. When injecting concrete into the mold, the concrete delivery pipe enters from the opening at one end of the mold and extends into the other end of the mold, and then the delivery pipe begins to spread evenly. The concrete is conveyed and the concrete enters the mould. [0003] Due to the long length of the pipe pile mold, the length of the conveying pipe that can extend in...

Problems solved by technology

[0003] Due to the long length of the pipe pile mold, the length of the conveying pipe that can extend into the pipe pile mold also needs to be long enough. The conveying pipe conveys a certain amount of concrete into the pipe pile mold at one time, and then weighs the mold together with the injected concrete , so that it reaches the preset value. After multiple injections, the total amount of concrete in the mold and the interior reaches the preset weight. The part of the conveying pipe that extends into the pile cannot be supported by other structures, which leads to a large gap at the front end of the concrete conveying pipe. There is no support for a long period of time, and the gravity at the front end of the delivery pipe will make it bend or even break when used for a long time, which will affect the accuracy of the amount of concrete fed, and then affect the quality of the product
