Construction process, the use of concrete pump repair

Concrete pump is now one of the most commonly used construction machinery, the main role is and concrete mixer used in conjunction with the construction now, and will require substantial use of concrete mixer, with the help of the project are very large, so when the concrete pump When the car encounters a failure, how to deal with, the following give an analysis of concrete pump truck when it encounters an error how to tackle and repair.

The exact location and physical characteristics of the Boom Crash
Ear hinge point at the end of the two-arm completely broken, most of the fault trace is displayed as the old crack (knuckle arm Tail: The sections on one arm and the head of the connecting end section arm; arm section head: boom sections The next section is connected with the rear end of the arm. below) the other ear plate section trailing second arm completely distorted, big bend rod, small curved rod and because two-arm rear ear pull fracture caused by a knuckle arm head Ministry ear plate partial extrusion. In addition to a knuckle arm head portion is deformed, the rest are new cracks due to a two-arm rear plate fracture caused by ear.
Since a two-arm root cause ear plate fracture obvious to the naked eye is difficult to find, we need to measure defects such as deformation and boom cylinder, connecting rod damage.
Boom fault repair method
According to the analysis of the accident, summed up the boom repair method first one, two, three, four boom (up from the turntable at) hanging down. Detection of parts, focus on examination of a damaged section and second section of the second arm of the boom cylinder damage. After examination, the results are as follows: turntable, undercarriage, three, four arms, each arm cylinder intact sections; one section two arm connecting pin, copper sets, three, four arm connecting pin, copper sleeve, arm, copper sets the turret connector is damaged, need to measure manufacturing; head section arms except a small place is crowded two-arm bending stress at other deformation is small, does not affect the assembly performance and use; the roots of a second arm section ear plate has been completely pulled crack, but also because of the ear on the other side plate cracking and seriously distorted; connecting a large section of the second arm bent rod and large-link is also due to two-arm lug plate fracture.
These are the reasons concrete pump experience a failure of analysis, breaking down in the face, we must first ensure the safety of personnel, and then analyze the cause of the malfunction, repair in accordance with article content was analyzed in order to ensure maximum efficiency of the project. In this article from the mixing station parts manufacturers Jin Ming Metallurgical Machinery website Xiaobian finishing release, Jin Ming Metallurgical Machinery manufacturers are specialized in manufacturing all kinds of accessories mixer, mixing station accessories and seal parts and other engineering machinery and equipment manufacturers.
