Abstract
The utility model relates to a speed differential anti-dropping device for a climbing rope. The speed differential anti-dropping device comprises a frame, a speed differential and a guide pulley fixed on the frame, a rope threading in from one side of the speed differential and threading out from the other side of the speed differential and led out from the frame via the guide pulley circumference, and a lock catch ring provided on the side wall of the frame. The speed differential anti-dropping device provided by the utility model has simple structure, simple and convenient installation, double safety protection, no dropping after installation, light weight and small size, and is especially for use in highrise operation of electric systems and other fields.
Description
Technical field
The utility model belongs to safety device, particularly a kind of rope speed differential anti-fall device of ascending a height.
Background technology
In the at present domestic work high above the ground field, the work high above the ground personnel do not have a desirable protection equipment, all are to tie up on waist through the safety rope that gets off from high empty set to be caught hold of by the security official usually, and randomness is bigger, and potential safety hazard is big.
Summary of the invention
The purpose of the utility model is a kind of rope speed differential anti-fall device technical scheme of ascending a height that proposes to the problems referred to above; This scheme is lived a speed difference device and a leading block through a frame fixation; Pass in the poor rapidly device of safety rope; Make a response rapidly and stop safety rope to slide when quick slip speed per hour difference device appears in safety rope, and then realized safe anti-fall.
To achieve these goals; The scheme of the utility model is: a kind of rope speed differential anti-fall device of ascending a height; Comprise a framework; Be fixed with a speed difference device and a leading block in the framework, the opposite side that a side of a poor rapidly device of rope penetrates poor rapidly device passes through the leading block circumference draws from framework, and the sidewall of said framework is provided with the snap close ring.
Also be provided with rope up and down respectively in side of leading block in the said framework and help to pulley and rope anticreep pulley, said rope is walked around 1/2nd leading block circumference at least and is helped to pulley from rope and draw.
Be installed with fixedly snap close of turntable on the said snap close ring, said turntable fixedly snap close includes right angle locking bar and locking nut, and the right angle locking bar is provided with screw thread, and locking nut is spun on the right angle locking bar, on the right angle locking bar of locking nut inboard, is with the lock hook piece.
Said right angle locking bar is to be formed by connecting through snap close two straight locking bars.
The utility model is simple in structure, and simple and fast is installed, and the dual fail-safe protective device is arranged, and can not come off after installing, and in light weight, volume is little, is particularly suitable for multiple field work high above the ground personnel uses such as power system.
Below in conjunction with accompanying drawing and embodiment the utility model is made a detailed description.

Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model rope structural representation that detours;
Fig. 3 is the utility model side schematic view;
Fig. 4 is a fixedly snap close sketch map of the utility model side band turntable.
The specific embodiment
A kind of rope speed differential anti-fall device of ascending a height; Referring to Fig. 1 to Fig. 4; Corresponding device comprises a framework 1; The opposite side that a side that is fixed with a speed difference device 2 and 3, one poor rapidly devices of rope 4 of a leading block in the framework penetrates poor rapidly device passes through the leading block circumference draws from framework, and the sidewall of said framework is provided with snap close ring 5.
Speed difference device among the embodiment is a kind of prior art; In order to guarantee that rope passes smoothly on leading block; Also be provided with rope in the said framework in side of leading block up and down respectively and help to pulley 6 and rope anticreep pulley 7, said rope is walked around 1/2nd leading block circumference at least and is helped to pulley from rope and draw.
Framework described in the embodiment is the framework that is connect by the weld all around of metallic plate phase, also can be the frame aluminium alloy extrusions, and speed difference device and leading block are through bearing pin and be bolted in the framework.
In the application of reality; Said device is to be fixed on the shelf that will ascend a height, in order to guarantee fixation, is installed with fixedly snap close 8 of turntable on the said snap close ring; Said turntable fixedly snap close includes right angle locking bar 8-1 and locking nut 8-2; The right angle locking bar is provided with screw thread, and locking nut is spun on the right angle locking bar, on the right angle locking bar of locking nut inboard, is with lock hook piece 8-3.For said right angle easy to carry locking bar at ordinary times is to be formed by connecting through snap close two straight locking bars.
The use principle of this device is: with this device through turntable fixedly snap close be fixed on the brandreth in multiple work high above the ground places such as electric power, wind-powered electricity generation, building, communication, bridge; The work high above the ground personnel carry rope and upwards climb; Per 3 meters are passed one on brandreth, be provided with one with rope and knot until the scope of operation; Knotting of per 3 meters settings is to prevent that the dynamics of falling when the rope distance is long is excessive, injury operating personnel safety; Knot and speed difference device formation dual fail-safe protective device; Former the comprehending of falling and producing the speed difference when speed per hour difference device utilizes object tenesmus to quicken as the work high above the ground personnel rapidly with rope stretch; Prevent that the work high above the ground personnel from falling; This device rope is capable of expansion and contraction from 10 meters to 100 meters, and the people is accidental falling horse back locking when work high above the ground, has effectively ensured personal safety; Be in the present domestic work high above the ground field, work high above the ground personnel's a desirable protection equipment.This device is installed simple and fast, and the dual fail-safe protective device is arranged, and can not come off after installing, and in light weight, volume is little, obtains the extremely outstanding evaluation of work high above the ground personnel in multiple fields such as power systems.
