Hose winder and engineering machine

Abstract

The invention provides a hose winder and an engineering machine. The hose winder comprises a winding drum on which a hose is wound, the hose is connected with an actuating part, and moreover, the hose winder also comprises a linear part, a reel, a first fixing part and a connecting mechanism; the linear part is connected with the reel and the actuating part; the reel can rotate relative to the first fixing part, and an elastic part is arranged between the first fixing part and the reel, and can apply pull force on the reel, so that the linear part can be retracted; the connecting mechanism is arranged between the reel and the winding drum; in at least one working condition, the linear part is pulled by the actuating part, and the pull force on the linear part is transmitted by the connecting mechanism, so that the hose is retracted. The hose winder can tension the hose without needing to depend on the action of a coil spring, and has the advantages of compact structure, light weight, self-adaptive following, adjustable tensile force, easy serialization, low cost and the like, driving is not needed, and the number of the turns of the wound hose is large.

Description

technical field [0001] The invention mainly relates to the field of construction machinery, in particular to a hose winding device and construction machinery including the hose winding device. Background technique [0002] During the operation of construction machinery, the executive components are often located in different working positions relative to the vehicle body. The hoses supplied by the hydraulic lines usually need to move with the movement of the actuator. The hose is generally wound on a reel and retracted according to the position of the actuator. The hose winding device needs to meet two requirements: first, the hose of the hose reel can be automatically released and tightened when the actuator moves; Big pull. [0003] figure 1 Shown is a schematic structural view of a prior art hose winding device. The hose winding device comprises a reel 1', on which a scroll spring 3' is arranged, and the hose 2' is wound under the action of the scroll spring 3'. The...

AI Technical Summary

Problems solved by technology

Simultaneously, the performance requirements of the device itself to the scroll spring 3' have also greatly increased the production and use costs of the scroll spring.

[0004] In addition, the stretching pretightening force of the reel of the structure increases with the extension of the hose, and the recovery pretightening force increases accordingly, which will increase the strength of the driving parts and connecting parts, and the shape and structure will become It is bulky, and the excessive pulling force causes some unnecessary malfunctions of the actuator, which seriously affects the normal operation of the actuator
