Problems solved by technology

[0004] 1. Concrete segregation affects all aspects of concrete performance;
[0005] 2. The segregated aggregate in the concrete impacts and rubs against the inner wall of the end concrete delivery elbow 20' at high speed, causing rapid wear and wear of the elbow, which greatly reduces the service life and loses the use function
This problem leads to the fact that the service life of the concrete delivery elbow with a nominal service life of 30,000 cubic meters for pump trucks and placing machines is generally about several thousand cubic meters at this position. When pumping poor concrete materials, the service life may even be less than 1,000 cubic meters. , which seriously affects the overall service life of the concrete delivery pipe

Embodiment Construction

[0028] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0029] The arrows in the figure point to the concrete conveying direction.

[0030] Such as figure 2 , image 3 with Figure 4 As shown, according to the first embodiment of the present invention, the elastic damper 10 includes a positioning notch 11 and an elastic damping tube 12 disposed on one side of the positioning notch 11 . The positioning notch 11 is a flange structure arranged at the mouth of the elastic damping tube 12 . The elastic damping tube 12 includes an elastic wall 13 protruding toward the central axis of the elastic damping tube 12 and an outer connecting wall 14 disposed on the outer periphery of the elastic wall 13 . The elastic wall 13 is fixedly connected to the positioni...

Abstract

The invention provides an elastic damper, a material distribution arm support and concrete material distribution equipment. The elastic damper comprises an elastic damping tube (12), wherein the elastic damping tube (12) comprises an elastic wall (13) protruded towards the pipe center axis of the elastic damping tube (12). According to the elastic damper, a separation phenomenon caused by overhigh motion speed of concrete can be avoided, and the phenomena of high speed impact and abrasion on a conveying bent tube, which are caused by overhigh speed of separated aggregates, are avoided, so that the service life of the conveying bent tube is prolonged.

Description

technical field [0001] The invention relates to the field of concrete distribution machines, in particular to an elastic damper, a distribution boom and concrete distribution equipment. Background technique [0002] The key component of the concrete pump truck and the distribution machine is the distribution arm that transports the concrete to the distribution position. The cloth boom is composed of several boom sections hinged to each other, and the boom sections are driven to rotate through the connecting rod cylinder mechanism. When fabricating, the boom is arranged in various postures to meet the fabric needs of the construction site. The common laying posture is that the jib rises, passes through the building, the end boom sinks, and the end hose is placed at the laying point for laying. The concrete is delivered to the delivery pipe attached to the boom device, and is delivered to the outlet of the end hose under the continuous push of the pumping device. [0003] S...
