Abstract
The utility model discloses a self-locking device for safety ropes of pulling ropes. The locking device for safety ropes is composed of a frame body, a pulley block, a front bracket, a rear bracket, a screw clamping mechanism, and a self-locking mechanism, wherein, the screw clamping mechanism is arranged under the frame body, and the self-locking mechanism is arranged above a postposition pulley of the pulley block. The utility model has simple structure and convenient use and can provide reliable supporting points for fixing safety ropes for rescue persons in various places, the utility model has strong reliability and strong safety and can make rescue persons and auxiliary persons implement rescue work securely to provide convenience for the development of rescue actions.
Description
The utility model relates to a kind of cable traction foolproof apparatus.It is suitable for various types of rescues and hangs operation.
At present at the rescue that utilizes rope with hang in the operation, people continue to use simple artificial supplementary form always.Promptly hold safety rope all the time, more as required and the folding and unfolding rope by the support staff.This mode of operation not only allows the shop support staff difficultly require great effort, and refreshing essence is among the high-pressure state, and its reliability and security extreme difference all.As the support staff mishap is arranged slightly, will cause serious consequence.Therefore in rescue operation, press for the life security that a kind of rope safety device is guaranteed the rescue personnel.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art.And provide a kind of simple in structure, easy to use, good reliability, safe safety rope lock.
The purpose of this utility model reaches by following technical measures: this safety rope lock is made up of support body, spiral clamp mechanism, assembly pulley, fore-stock, after-poppet and self-locking mechanism.Wherein the spiral clamp mechanism is arranged on the bottom of support body.The preposition pulley of assembly pulley is the front that is fixed on support body top by fore-stock; The rearmounted pulley of assembly pulley is the back that is fixed on support body top by after-poppet.And self-locking mechanism is arranged on the top of the rearmounted pulley of assembly pulley.
Spiral clamp mechanism of the present utility model can be made of fixing chuck, movable chuck, screw rod, the nut and the crank that are fixed on the support body.
Self-locking mechanism of the present utility model can be made of extension spring, latch, dead axle and handle.Wherein the upper end of extension spring is fixed on the top of after-poppet, and the lower end of extension spring and the front end of latch join.Latch is to be set on the dead axle that is fixed on the after-poppet.The lower surface of latch has the cambered surface that matches with the pulley circular arc.The latch rear end is equipped with handle.
The drawing of accompanying drawing is described as follows:
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is the left view of Fig. 1.
The utility model is described in further detail below in conjunction with embodiment: this safety rope lock is made up of support body (1), spiral clamp mechanism (2), assembly pulley (3), fore-stock (4), after-poppet (5), self-locking mechanism (6).Wherein spiral clamp mechanism (2) is arranged on the bottom of support body (1).It is by fixedly chuck (2-5), movable chuck (2-4), screw rod (2-3), nut (2-2) and crank (2-1) are formed.Fixedly chuck (2-5) is to be fixed on the support body (1), and movable chuck (2-4) is that the front end with screw rod (2-3) links together.Screw rod (2-3) is to be set in the nut (2-2) that is fixed on the support body (1).The rear end of screw rod (2-3) and crank (2-1) join.Assembly pulley (3) is divided into preposition pulley (3-1) and rearmounted pulley (3-2).Preposition pulley (3-1) is the front that is fixed on support body (1) top by fore-stock (4).Rearmounted pulley (3-2) is the back that is fixed on support body (1) top by after-poppet (5).Self-locking mechanism (6) is arranged on the top of the rearmounted pulley (3-2) of assembly pulley (3).It is made of extension spring (6-1), latch (6-2), dead axle (6-3) and handle (6-4).Wherein latch (6-2) is to be set on the dead axle (6-3) that is fixed on the after-poppet (1).Latch (6-2) can rotate around dead axle (6-3).Lower surface at latch (6-2) is processed with the cambered surface that matches with the pulley circular arc.Be fixed with handle (6-4) in the rear end of latch (6-2).And the lower end of the front end of latch (6-2) and extension spring (6-1) joins.The upper end of extension spring (6-1) is fixed on the top of after-poppet (5).
When this safety rope lock uses, at first find suitable body of wall or building structure, two chucks of this lock are placed the wall body structure both sides.Rotating crank then allows two chucks tightly be clipped on the wall body structure.So whole safety rope lock is by firmly on wall body structure.Then lift the locking handle, safety rope is wrapped on the assembly pulley.Just safety rope can be fastened on rescue personnel's body afterwards.After the rescue personnel is sent to the area of recovering.Latch only needs the locking handle is put down, owing under the effect of extension spring, will can not move freely rope to the pressure of the generation of the rope body on the rearmounted pulley more than 40 kilograms.Meanwhile rope is subjected to downward tractive force and also allows the rope body that latch is produced counteractive frictional force, forms the anti-moment of doing the rope body is produced from compaction forces, thereby the locking rope suspends the purpose of human body in midair to reach safety.Can allow the support staff of fixing point needn't hold rope on the other hand again, can free hand to participate in other rescue operation fully.
The utility model has following advantage compared to existing technology: this locking device of safety rope is simple in structure, uses Convenient, can provide reliable safety rope fixed support point for the rescue personnel at the terrain of Various Complex. And its reliability is extremely strong, and security is very high, can allow rescuer and support staff go very relievedly reality Sue and labour and help operation, be very easy to carrying out of rescue action.
