Abstract

PURPOSE:To increase the recoil strength of a tube used in a squeezing concrete pump, by forming a pump case in a hermetical manner, and charging a liquid in the pump case. CONSTITUTION:When a pair of rollers 4 are turned in tight contact with a tube 7, a vacuum space V is formed. By the vacuum force of the vacuum space V, the tube 7 flattened restores its round cross section. Since the frictional heat produced by relative slipping of the surfaces of a pad 6, the tube 7 and the rollers 4 is absorbed by a liquid in a pump case 1, it is enabled to increase the recoil strength of the tube used in a squeezing concrete pump.

[Detailed description of the invention] A pumping action is applied to the tube by the tube suppressing action by an uninvented roller and the restoring action of the tube itself, so that the concrete is pumped into the tube, and the inhaled confetti is also pumped. This invention relates to a squeeze-type concrete pump.

Generally, in this type of squeeze-type concrete pump, the tube that has been pressed into a flat shape by rollers is restored, and the restoring force of this tube is used to compress the concrete inside the hopper, which is connected to the tube suction side. It is inhaled into a tube.

Therefore, if the restoring force of the tube is weak, the amount of suction into the tube will be small, causing a problem that efficient pumping cannot be performed.

For this reason, in the past, the inside of the pump case was sealed, and the inside of the pump case was evacuated by driving a separate vacuum valve, and this vacuum force restored the compressed flat tube to a perfect circle. This allows more concrete to enter the tube, resulting in more efficient concrete pumping.

By the way, in the @se L-type concrete pump, frictional heat is generated by the slip between the pad surface and the tube surface or the roller and the tube surface when the concrete is compressed by the roller and the inside of the case is pumped. Because it is in a vacuum, it is difficult for it to escape outside the case, which shortens the life of the tube.

As described above, in the present invention, when a liquid is filled in a sealed case and the tube is compressed by a roller, a volume change occurs and a vacuum portion is created in the case.
The tube 1l- is compressed by the vacuum force of this vacuum part.
j This ensures that the cross section is restored to a perfect circular shape, which allows for efficient pumping. Furthermore, even if frictional heat is generated due to slippage between the pad and the tube or between the tube and the roller, this heat is absorbed by the liquid.
This has the feature that the tube does not become high temperature and the life of the tube is extended.
