Embodiment 1

[0025] Such as image 3 As shown, the end hose safety device of the pump truck of the present invention includes a fixed ring 10 fixed on the upper part of the end hose 9 and a reset ring 14 fixed on the middle of the end hose 9, and the tension ring 12 can be moved up and down on the end hose. 9 and located between the fixed ring 10 and the reset ring 14, it is connected to the fixed ring 10 through 4 tension safety ropes 11 arranged on the side of the end hose 9, and the tension ring 12 and the end hose 9 maintain a certain degree of looseness , can slide up and down; the lower part of the tension ring 12 is connected with the reset ring 14 through 8 return springs 13, wherein, the distance between the tension ring 12 and the reset ring 14 is based on the preload distance of the return spring 13. In this embodiment, the reset The length of the spring 13 is 1 cm, the total length of the end hose is 3 meters, and the height of the tension ring is 10 cm to ensure that the tensi...

Embodiment 2

[0027] The difference from Example 1 is that the total length of the end hose is 3 meters, the height of the tension ring 12 is 11 cm, and the length of the return spring 13 is 2 cm. All the other operating modes are the same as in Example 1.

Embodiment 3

[0029] The difference from Example 1 is that the total length of the end hose is 3 meters, the height of the tension ring 12 is 12 cm, and the length of the return spring 13 is 3 cm. All the other operating modes are the same as in Example 1.

[0030] The present invention is obtained through long-term production practice and creative labor by technical research and development personnel, and it has been tried out in the company. Due to the low production cost and good application effect of the present invention, it is well received by front-line workers.

Abstract

The invention discloses a safety device for a tail end hose of a pump truck. The safety device is used for reducing swing of the tail end hose (9), and is characterized in that the safety device comprises a fixed ring (10) fixed at the upper part of the tail end hose (9), and a return ring (14) fixed at the middle part of the tail end hose (9), wherein a tension ring (12) is arranged in the tail end hose (9) in an up and down movable manner, positioned between the fixed ring (10) and the return ring (14), and connected with the fixed ring (10) by tension safety ropes (11) arranged at the edge of the tail end hose (9); and the lower part of the tension ring (12) is connected with the return ring (14) by a return spring (13). The safety device has the advantages that the safety device can limit instant swing of the tail end hose, so that the operational safety performance of the tail end hose is improved, and a danger coefficient during construction is reduced.

Description

technical field [0001] The invention relates to a fixing mechanism for a hose at the end of a pump truck, in particular to a safety device for a hose at the end of a pump truck. Background technique [0002] With the development of urban construction, the requirements and reliance on mechanization technology in urban construction are getting higher and higher. Since the concrete delivery pump truck (referred to as pump truck) is more flexible and convenient in pouring concrete, it has become the leading concrete pouring in the construction industry. One of the devices. Concrete pump truck is a machine that uses pressure to continuously transport concrete along a specific pipeline, such as figure 1 As shown, it is mainly composed of chassis 1, pumping mechanism 3, boom system 2 and so on. The boom system is the more dangerous part of the concrete pump truck; the system is mainly composed of multi-section boom 4, connecting rod 5, oil cylinder 6 and connector 7, etc., and th...
