Abstract
The utility model relates to the safety protection field preventing a steel wire rope from loosing and breaking, particularly to a device for protecting the steel wire rope from loosing and breaking and aims to provide the device which has a simple structure, is convenient to mount, and can control the on-off of a limit switch along with the loosing state of the steel wire rope, so as to fulfill the purpose of protection. The device comprises a base, a bracket, an induction arm and a travel switch, wherein the base is fixed on a winch; the bracket is perpendicularly erected on the base and fixed through a bolt; one end of the induction arm is connected with the bracket through a bolt, and an inductive pinch roller is arranged at the other end of the induction arm; the inductive pinch roller is arranged on the steel wire rope; the inductive pinch roller, the induction arm and the travel switch are connected with a control system through a sensor; a rope wheel is arranged on one side of the bracket; the steel wire rope is arranged on the rope wheel. The device has a simple structure, is convenient to mount, particularly suitable for the winch and a theatre stage hoisting system and high in practicality, and has a broad market prospect.
Description
Technical field
The utility model relates to the disconnected rope of a kind of pine limiting device, belongs to the field of hanging, and is specifically related to a kind of loose rope broken protector.
Background technology
At present, in a lot of occasions, all use steel rope as the suspender medium, as the studio upper space lifts all kinds of filming apparatus and light fixture equipment etc., often a large amount of steel ropes that use are as the suspender medium.Our said winch namely, winch (being again winch) is to drive reel, coiling rope to complete the device of traction work by manpower or mechanical power.Can vertical-lift, level or inclination drag and draw weight.Winch is divided into two kinds of manual hoist and electric winchs.Take electric winch now as main.Electric winch is comprised of electrical motor, plunging joint, drg, gear case and reel, jointly is arranged on frame.For lifting altitude and the large work of volume of goods loaded and unloaded situation frequently, good speed adjustment features, can make empty hook fast-descending.To installation in position or responsive material, can use less speed.Yet in use, because hanging object often will carry out displacement according to actual conditions, therefore be prone to steel rope and the cylinder angle is excessive, cause steel rope on cylinder, arrange inhomogeneous, degree of tightness is inconsistent, so that the load-bearing of each point steel rope is unbalance, cause suspender to topple or steel rope damages the accidents such as disconnected; Simultaneously steel rope with by hanging object fixedly the time, each point tightness of steel wire rope degree is inconsistent, also easily causes steel rope to damage disconnected or lax, long-term use there will be potential safety hazard.In order to ensure being perfectly safe of equipment, will install safety device additional at the links of hanging equipment, to eliminate safe hidden trouble.
Summary of the invention
The utility model purpose is to provide a kind of disconnected fender guard of steel rope pine that can prevent from hanging, and it is simple in structure, easy for installation, can control the closed of limit switch and open with the degree of tightness state of steel rope, plays a protective role.
For achieving the above object, the utility model is achieved in that a kind of loose rope broken protector, comprise base, support, sensing arm and travel switch, described base is fixed on winch, and described support vertical is erected on base, and is bolted; Described sensing arm one end is connected with support by bolt, and the described sensing arm other end is provided with the induction pinch roller, and described induction pinch roller is arranged on steel rope, and described induction pinch roller, sensing arm and travel switch are connected with control system by inductor.
Described support one side is provided with rope sheave, and described rope sheave is provided with steel rope.
Technique scheme is further analyzed; described support is the supporting mechanism of sensing arm; sensing arm is played a supporting role; sensing arm is the direct-detection mechanism of loose breaking rope protecting signal; after the steel rope pine is disconnected, sensing arm can under the effect of own wt, around him, the rotation of the hinge on support descends, when touching travel switch; send electric signal to control system by travel switch, winch is stopped operating.
The disconnected rope of the pine that the utility model provides limit switch, utilize the induction pinch roller of sensing arm front end to be positioned on steel rope, and under normal circumstances, steel rope is tensioned state, and travel switch is in normally closed.When steel wire rope looseness or disconnection, due to the effect of gravity, sensing arm can under the effect of own wt, around him, the rotation of the hinge on support descends; when touching travel switch; send electric signal to control system by travel switch, winch is stopped operating, thereby play the effect of safety guard-safeguard.
The utility model has the advantages that:
1, simple in structure, easy for installation, can control the closed of travel switch and open with the degree of tightness state of steel rope, play a protective role.
2, extensively adapt to various installation environments, especially applicable winch, stage arenas hangar system, practical, there are wide market outlook.

The specific embodiment
A kind of loose rope broken protector: it comprises base 1, support 2 and sensing arm 3, and base 1 is fixed on winch, and support 2 stands vertically on base 1, and is bolted, sensing arm 3 one ends are connected with support 2 by bolt, support one side is provided with rope sheave 5, rope sheave 5 is provided with steel rope 4, sensing arm 3 other ends are provided with induction pinch roller 31, induction pinch roller 31 is arranged on steel rope 4, support 2 is supporting mechanisms of sensing arm 3, sensing arm 3 is played a supporting role, sensing arm 3 is direct-detection mechanisms of loose breaking rope protecting signal, after steel rope 4 pines are disconnected, sensing arm 3 can under the effect of own wt, around him, the rotation of the hinge on support 2 descends, when touching travel switch, send electric signal to control system by travel switch, winch is stopped operating, thereby play the effect of safety guard-safeguard.
Claims (2)
1. a loose rope broken protector, it is characterized in that: it comprises base, support, sensing arm and travel switch, and described base is fixed on winch, and described support vertical is erected on base, and is bolted; Described sensing arm one end is connected with support by bolt, and the described sensing arm other end is provided with the induction pinch roller, and described induction pinch roller is arranged on steel rope, and described induction pinch roller, sensing arm and travel switch are connected with control system by inductor.
