Air pressure brake type hydraulic coupling hose or cable coiling block

Abstract

The invention discloses an air pressure brake type hydraulic coupling driving hose or cable coiling block. A hydraulic coupler is connected with a drive motor through a rigidity coupler. The drive motor is controlled by an electrical control box to rotate forwards and reversely and drives the hydraulic coupler to rotate. A transition plate is connected with the drive motor and the speed reduction box, and the two ends of a connecting shaft are connected with an output shaft of the drive motor and a main shaft of the speed reduction box correspondingly. A brake frame of an air pressure brake is arranged on a connecting installing base through a fixing pin, and the main shaft of the speed reduction box is in rigidity connection with a reel. According to the air pressure brake type hydraulic coupling driving hose or cable coiling block, air pressure brake type hydraulic coupling is adopted for driving the hose or the cable, the speed of hose or cable winding and unwinding through the reel is adjustable, the winding and unwinding speed and the tension of the hose or the cable can be easily and conveniently adjusted in the hose or cable winding and unwinding process, and the hose or the cable can be more effectively protected.

Description

technical field [0001] The invention relates to a mobile energy supply device, in particular to a hose or cable reel driven by a pneumatic brake hydraulic coupling. technical background [0002] At present, the hose or cable reel is mainly driven by several forms of hydraulic coupling, variable frequency drive or hysteresis coupling. The above various driving forms have their own advantages and disadvantages, which are described as follows: the hose or cable reel driven by the hydraulic coupling, through the flexible driving system composed of the high-slip hydraulic coupling and the electrical controller, is relatively It solves the problems of high frequency, high speed and high reliability of retracting and releasing hoses or cables. However, because the hydraulic coupling is rotated by the high-speed liquid, the coupling turbine is subjected to the impact force of the hydraulic oil, so the hydraulic coupling hose or cable reel needs to maintain a fast retracting speed, ...

AI Technical Summary

Problems solved by technology

In addition, the hydraulic coupling can only transmit the input torque to the output device unchanged.

Due to the above characteristics, the speed and winding force of the hose or cable reel driven by the hydraulic coupling are not easy to control and adjust during the process of retracting the hose or cable. impact tension failure

[0003] The hose or cable reel driven by frequency conversion needs to customize the frequency converter, and the control is complicated, especially for the working conditions with large moment of inertia, high acceleration and fast speed, which cannot meet this requirement very well

And due to acceleration requirements, in terms of response speed, frequency conversion speed regulation reels usually have to reduce energy efficiency, which can only be solved by using a large horse-drawn cart, which cannot effectively protect hoses or cables

[0004] Hose or cable reels driven by hysteresis coupling, due to the high back-pull force when laying down the tube or cable, the hose or cable is prone to injury

In addition, the torque provided by the hysteresis coupler must be controlled by adjusting the air gap between the induction disc of the hysteresis coupler and the disk, and the adjustment is not very convenient.
