Tail end hose device, concrete pump vehicle and pipeline transporter

Abstract

The invention discloses a tail end hose device used for a concrete pump vehicle, comprising a delivery pipe (1). The lateral wall of the delivery pipe (1) is sleeved with a mass disc (2), and a gap is arranged between the side wall of the inner ring of the mass disc (2) and the lateral wall of the delivery pipe (1); and a support part protruding out of the lateral wall of the delivery pipe (1) is arranged at least one of the upper and down parts of the mass disc (2), and the mass disc (2) is connected the with the support part through a flexible part so as to facilitate the mass disc (2) to reciprocate along the axial direction of the delivery pipe (1). The device can effectively reduce the vibration when the tail end hose device delivers materials, and has high the reliability of reducing vibration and low operation cost. In addition, the invention also discloses a concrete pump car comprising the tail end hose device. Furthermore, the invention discloses a pipeline delivery device.

Description

technical field [0001] The invention relates to the technical field of concrete pump trucks, in particular to a terminal hose device. In addition, the present invention also relates to a concrete pump truck comprising the end hose device. Furthermore, the present invention also relates to a pipeline delivery device. Background technique [0002] With the rapid development of my country's construction industry, the demand for construction machinery, especially concrete pump trucks, is also increasing. [0003] Please refer to figure 1 , figure 1 It is a structural schematic diagram of the terminal hose device of the concrete pump truck in the prior art. [0004] The terminal hose device includes an inner sleeve 1', an outer sleeve 2' and a rubber hose 3'. The inner sleeve 1' is connected to the distribution boom of the concrete pump truck, thereby realizing the connection between the end hose device and the distribution boom. The placing boom is arranged on the boom of t...

Problems solved by technology

This vibration damping device can effectively reduce the vibration of the component 5'3 to be damped, but this vibration damping device is not suitable for installation on the boom of a concrete pump truck, because the boom does not have a large space to install the boom after it is folded. Vibration damping device, which is therefore not suitable for reducing the vibration of the boom of the concrete pump truck, and thus not suitable for reducing the vibration of the end hose assembly

[0010] At present, domestic and foreign research on boom vibration reduction technology has gradually deepened. Most of them reduce boom vibration by optimizing the mechanical structure and hydraulic system control strategy, such as using closed-loop hydraulic control system for vibration reduction, but closed-loop hydraulic control system hydraulic pressure The high oil temperature has certain requirements on the service life of valves and electrical components, and the vibration damping structure is relatively complicated, which is difficult to implement and the work cost is relatively high
