Description
Technical Field

Background
One of the core systems of the concrete pump truck is a pumping unit, which comprises a main oil cylinder, a concrete cylinder, a hopper, a distributing valve and the like. The spectacle plate and the cutting ring are used as key components of the distributing valve, and the spectacle plate is fixed, and the cutting ring is connected with a moving component S pipe. Under the action of the swing oil cylinder, the S pipe drives the cutting ring to swing from one concrete conveying hole to the other concrete conveying hole of the glasses plate, the cutting ring swings reciprocally around the fixed center, and a pair of plane friction pairs are formed on the end faces of the glasses plate and the cutting ring.
When the spectacle plate and the cutting ring work, concrete abrasive particles are worn, eroded, sheared and the like, and the failure mode mainly comprises serious wear of a plane friction pair material, falling of a hard alloy block, serious erosion of inner walls of two material conveying holes of the spectacle plate and serious erosion of inner circular surfaces of the cutting ring; especially along with the increase of pumping pressure required by high-rise buildings, high-speed and high-pressure concrete jet flow is formed at the gap at the moment when the conveying holes of the cutting ring of the glasses plate are completely closed, so that the range of 90 degrees in the 2-5 o ' clock direction, the range of 90 degrees in the 7-10 o ' clock direction and the range of 90 degrees in the 7-5 o ' clock direction of the inner wall of the two conveying holes of the glasses plate, the range of 90 degrees in the 7-10 o ' clock direction of the inner surface of the conveying holes of the cutting ring, and the range of 90 degrees in the 7-10 o ' clock direction are seriously eroded, thereby directly leading to the long service life of the cutting ring of the glasses plate, having to stop for replacement and seriously affecting the pumping efficiency of concrete.
In the prior art, in order to improve the service lives of the eyeglass plate and the cutting ring, a common mode is to weld a hard alloy block and an alloy ring at a vulnerable part or directly build up a wear-resistant layer, etc. However, because the steel matrix and the hard alloy are different materials, the linear expansion coefficients are different by more than 1 time, and the joint shapes are different; moreover, the welding is easy to deform, the residual internal stress is large, the defects of welding holes, slag inclusion and the like are many, the full welding rate is low, and the binding force is small; the surfacing material has insufficient wear resistance and erosion resistance, and the service life of the eyeglass plate and the cutting ring is still difficult to meet the higher requirements of the industry due to the fact that cracks of a surfacing layer in a common process are difficult to control.
