A reel device and refueling truck

Abstract

The invention provides a winding device and a fuelling vehicle. The winding device comprises a winding frame, a guide assembly mounted on the winding frame and a damping device mounted on the guide assembly, wherein the winding frame comprises a central shaft and a baffle plate; the guide assembly comprises a two-way lead screw and a guide element which sleeves the two-way lead screw, and cable-pipe inlet and outlet are formed in the guide element; the damping device comprises a U-shaped damping roller, a spring connected with the U-shaped damping roller and the guide element, respectively, and a locking device for controlling the angle of rotation of the U-shaped damping roller with an end thereof as a rotation point. The damping device, under the control of the locking device, is capable of applying resistance to a cable or a pipe on the winding device according to requirements, so that the cable or the pipe can be tightly wound around a central shaft of the winding device when being reeled, and when the cable or the pipe is unreeled, the cable or the pipe can be quickly unreeled without being affected by the resistance. The winding device is capable of keeping the cable or the pipe wound around the central shaft regular and tidy, and also capable of guaranteeing quick unreeling of the cable or the pipe.

Description

technical field [0001] The invention relates to the field of retracting and unwinding cables and pipes, in particular to a reel device for controlling the release and retraction of cables and pipes and a refueling vehicle equipped with the reel device. Background technique [0002] In many industries, there is repeated use of cables and pipes, including the operation of releasing and retracting corresponding cables and pipes, such as cables, fire hoses, telephone lines, and fuel pipes. This type of operating device generally utilizes a reel structure with a shaft in the middle and baffles at both ends, and the cables and pipes are released and retracted through the rotation of the central shaft or the entire reel. [0003] In order to enable cables and tubes to be wound on reels in a compact manner. Some reels are provided with a locking mechanism made of elastic material that is sleeved on the outside of the cable and tube. The holes that pass through the cable and tube ar...

AI Technical Summary

Problems solved by technology

However, such guide components are rarely used on large-scale reels due to structural reasons, so large-scale reel devices usually require special personnel to straighten out the cables and tubes when they are retracted.

[0005] In addition, the automatic control of the reel in the prior art is generally set on the reel, such a structure allows the operator to return to the reel to operate when necessary

Or it needs to be specially equipped with a controller, which is less efficient
