Inner wall high-temperature quenching spiral rapid straight pipe for concrete pump truck

Abstract

The invention discloses an inner wall high-temperature quenching spiral rapid straight pipe for a concrete pump truck, which comprises two straight pipe bodies which are mutually inserted and a connecting sleeve arranged between the surfaces of the two straight pipe bodies in a sleeving manner, rifle grooves are formed in the inner walls of the two straight pipe bodies, sealing rings are fixed on the two sides of the connecting sleeve, and the connecting sleeve is connected with the straight pipe bodies in a sleeving manner. The invention relates to the technical field of inner wall high-temperature quenching internal spiral rapid straight pipes for concrete pump trucks. According to the inner wall high-temperature quenching spiral rapid straight pipe for the concrete pump truck, through the arrangement of the pressing sealing mechanism, multi-point extrusion can be conveniently conducted on the sealing ring, the sealing ring can be tightly attached to the surface of the straight pipe body, comprehensive sealing is achieved, then the sealing effect between the straight pipe body and the connecting sleeve can be improved, the leakage risk is greatly reduced, and the service life of the straight pipe is prolonged. And through the arrangement of the pipeline connecting and positioning mechanism, the two straight pipe bodies can be conveniently and rapidly connected and positioned, flange connection is not needed, and the two straight pipe bodies are very convenient to detach and separate.

Description

technical field [0001] The invention relates to the technical field of inner wall high-temperature quenched inner spiral fast straight pipe for concrete pump trucks, in particular to a high-temperature inner wall quenched spiral fast straight pipe for concrete pump trucks. Background technique [0002] The concrete pump truck is a machine that uses pressure to continuously transport concrete along the pipeline. It consists of pump body and delivery pipe. According to the structural form, it is divided into piston type, extrusion type and hydraulic diaphragm type. The pump body is installed on the chassis of the car, and then equipped with a telescopic or inflection boom, a pump truck is formed. The concrete pump truck is transformed from the chassis of the truck. It is equipped with movement and power transmission devices, pumping and mixing devices, distribution devices and other auxiliary devices on the chassis. The power of the concrete pump truck transmits the power o...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a high-temperature quenched spiral fast straight pipe with an inner wall for concrete pump trucks, which solves the problem that the existing high-temperature quenched spiral fast straight pipe with an inner wall for concrete pump trucks is generally connected by the direct passage method. It is very inconvenient to disassemble the connection with the blue plate. Nowadays, there are pipe connection sleeves for connection, but the sealing effect between the pipe connection sleeve and the straight pipe is average, and there is a risk of leakage.
