Adjustable tensioning guide device for retracting hose cable

Abstract

The invention discloses an adjustable tensioning guide device for retracting a hose cable, and the device comprises a mounting base plate, a driving pinch roller, a lower pressure-bearing wheel, a handle, a rocker arm, a screw rod, a pressure regulating nut, a pressure spring, a rotary connecting seat and a lower check nut, wherein the driving pinch roller and the lower pressure-bearing wheel are arranged at the frontage of the mounting base plate; the lower pressure-bearing wheel is positioned below the driving pinch roller; one end of the rocker arm is connected with the upper part of the mounting base plate, and the other end of the rocker arm is connected with the end part of the driving pinch roller by virtue of a pin shaft; one end of the rotary connecting seat is sheathed on the pin shaft positioned at the outer side of the driving pinch roller, and the other end of the rotary connecting seat is sheathed on the screw rod; the spring is sheathed on the screw rod arranged above the rotary connecting seat; the pressure regulating nut is sheathed at the end part of the screw rod; the lower check nut is sheathed on the screw rod arranged below the rotary connecting seat; the bottom end of the screw rod is connected with the lower pressure-bearing wheel by a pin shaft; and the handle is arranged on the pin shaft. The adjustable tensioning guide device can be used for changing the tensile force and the pressure gap by virtue of simple adjustment, thus adapting to different cables.

Description

Technical field [0001] The invention relates to an adjustable tension guide device for retracting and unwinding a hose and cable, in particular to a tension guide device additionally installed behind a cable reel, and belongs to the technical field of auxiliary devices for retracting and unwinding cables. Background technique [0002] At present, the auxiliary device used for the reel of the hose and cable is basically just a simple guide device, composed of four fixed guide wheels, which respectively limit the movement of the cable in all directions, because there is no cable When tension is applied, the reel cannot be tightly wound on the drum when the cable is recycled, and manual tension is required. This not only requires additional personnel, but also has low safety and efficiency. Therefore, how to operate cable recycling simply, effectively and conveniently and quickly has become a major problem in engineering applications. [0003] Summary of the invention [0004] The pu...

Problems solved by technology

[0002] At present, the auxiliary device used for the reel of the hose cable is basically just a simple guide device, which is composed of four fixed guide wheels, respectively restricting the movement of the cable in all directions up, down, left, and right, because there is no guide for the cable. When tension is applied, the reel cannot be tightly wound on the drum when retrieving the cable, and it needs to be tightened manually, which not only requires additional personnel, but also has low safety and efficiency
