An anti-running grinding safety protection device and a winch with the same

Abstract

The invention discloses an anti-running and grinding safety protection device. The shells on both sides are connected by connecting bolts, and the steel wire rope is arranged inside the gap between the shells on both sides; The first chute is arranged on the upper and lower sides of the hood, and the first chute is arranged obliquely from the left rear to the right front. The invention also discloses a winch mill with a safety protection device for anti-running grinding, which includes a base, vertical plates arranged on both sides of one end of the base, a second rotating shaft arranged between the vertical plates on both sides, and a second rotating shaft sheathed on the second rotating shaft. The external reel and the above-mentioned anti-running safety protection device. During the normal operation of the present invention, the rollers are in contact with the steel wire rope. When the winch mill runs, the steel wire rope moves in the opposite direction. The distance between the side rollers is reduced, and at the same time, the rollers exert a pressing force on the wire rope, thereby avoiding running grinding of the winch.

Description

Technical field [0001] The present invention belongs to the field of rope motion control technology, and in particular, the present invention relates to a procedure of the anti-run milling safety protection device and a strand having it. Background technique [0002] Wiring is one of the most commonly used mechanical equipment in transmission line construction. It is mainly used for traction operations, extensive applications in various processes of line construction, such as: Tower is formed, tightening line, and has a cable. [0003] In the on-site construction process, the unexpected conditions occurred substantially running, and the meaning of running is: when using the gentle, the traction rope that is wound on the strand is rapidly traction due to the normal traction of the strand. The reverse direction. If running, the strand is lost, and the traction rope will retracerate quickly, and the axial ringing direction is rapidly moved. If the scene personnel do not fall, it cau...

AI Technical Summary

Problems solved by technology

If running and grinding occurs, the winch will lose its function, and the traction rope will quickly withdraw, driving the wire axis to move rapidly in the direction of the winch. If the on-site personnel cannot dodge in time, it will cause injury or even death to the on-site personnel

[0004] Winch mills generally have different forms of braking devices, mainly including a set of auxiliary braking devices (working when the clutch is open) and a set of braking devices (working when abnormal reversing occurs, consisting of bearings and rollers) , immersed in transmission oil); in actual use, the access speed of the brake device will be affected by the viscosity of the transmission oil, especially in the low-temperature environment on the plateau, it is more likely to be affected, and it is prone to abnormal reversing of the winch (running Grinding) when the brake device does not work or does not intervene in time, resulting in safety accidents

Therefore lack a kind of safety device that can effectively play secondary protection under the situation that its braking device does not work, avoid the generation of safety accident
