Description
Technical field
The present invention relates to a kind of falling proof devices, and in particular to a kind of fall arrest dress applied on vertical-lift elevator
It sets.
Background technique
Currently, vertical-lift elevator occur the hidden danger of safety first is that the drag rope due to elevator is broken, cause
Elevator falls.There are safety when unreasonable structural design, use is poor for pure mechanic structure falling proof device in the prior art
The problem of, it can not achieve more safe and effective fall arrest purpose；Such as Patent No. " CN201710331942.1 ", title
It is that fall arrest is carried out by mechanical structure for the patent document of " one kind is used for vertical-lift elevator anti-falling self-locking device "
, when used during elevator falling is to 5 position of rack bar, ball roller bar 622 and stripe board 52 after stretching form self-locking angle, elevator
It is blocked, and stops falling by self-locking；Itself the problem is that ball roller bar 622 is overhanging after position is relatively fixed to bounce back,
Carriage, which can not move up, after being stuck can not also move down, and subsequent maintenance difficulty is big, therefore unreasonable structural design；Bulb simultaneously
Cylindrical bar 622 stretching be rely on effect of inertia be thrown out of, ball roller bar 622 can effectively throw away by uncertain factor influenced compared with
Greatly, such as between straight pin and/or ball roller bar 622 and blind hole 621 it is influenced by cargo sweat or into factors such as dusts and is increased
Big drag effect can then make individual ball roller bars 622 occur failing the case where being thrown out of in time, and elevator cannot be effective at this time
Stuck, safe effect is not good enough.Such as Patent No. " CN201820509116.1 ", entitled " elevator falling-proof safety device "
Patent document is to carry out fall arrest by mechanical structure, fills in 1 rapid descent of carriage by the elevator anti-falling safe
It sets, normal impact occurs for percussion hammer and impact head, and the entire arm that engages obtains larger kinetic energy, locking head is driven to move in a circle to carriage
It is close, critical localisation is crossed, card-stopping bar rests on limit brick side, and locking head encounters car side wall, and in permanent magnet piece
Under the action of be adsorbed on car side wall, until encounter stop block, under the support of limit brick, carriage stop motion；It exists
The problem of be that entire locking arm is unfavorable for being laid in elevator, unreasonable structural design；Head and stop block are engaged simultaneously
For instantaneous rigid contact, percussion is big, cannot be buffered by rubbing action, and the safety and stabilization of carriage are unfavorable for.
Summary of the invention
The purpose of the present invention is being directed to the deficiencies in the prior art, a kind of apply on vertical-lift elevator is provided
Falling proof device；Its is reasonable in design, can more safely and effectively realize elevator fall arrest purpose.
To achieve the above object the technical solution adopted by the present invention is that:
A kind of falling proof device applied on vertical-lift elevator, comprising:

Beneficial effects of the present invention:
Two tracks are fixed on elevator two sides to the present invention when in use, and stop sliding case moves in orbit, and carriage is clamped in
It is connect between two tracks and with stop sliding case；During the lifting moving of carriage routine, damping wheel can be on grip block
It rolls, and carriage can be moved down quickly after drag rope is broken, the revolving speed of damping wheel increases, torque improves, damping action
Reinforce, and it is made to move down the decrease speed of velocity lag cabinet, damping wheel drives differential crane to compress second spring phase at this time
Cabinet is moved up and is contacted with stopping wheel, stopping wheel and damping wheel generate rubbing action, make damping wheel stop, damping wheel and clamping
Plate generates friction, realizes fall arrest using frictional resistance, while stopping wheel also makes damping wheel opposite case transverse shifting outward,
The squeezing action power between damping wheel and grip block is increased, frictional resistance is increased, and then can more safely and effectively be realized
Stop slides the fixation of case relative orbit, to realize carriage stop；After the completion of drag rope replacement, it can pull in carriage
It moves, carriage drives cabinet to move up, and differential crane can gradually opposite case resets under second spring effect, damping wheel and stop
Wheel is rapidly separated, and the first spring is suitable for the variation of damping wheel lateral displacement, can realize that carriage smoothly moves up and down at this time.This hair
Stop sliding case and track in bright are conducive to be laid in elevator in design feature, can realize in structure design anti-
It falls purpose, while structure design upper stop sliding case and track locks when falling are after death, and realization can be moved up by carriage automatically
Unlock, the maintenance after falling convenient for elevator；The present invention realizes damping wheel when to carriage fall arrest, using stopping wheel
Stop, while damping wheel also being promoted to move the frictional resistance increased between damping wheel and track lateral out, make stopping effect more preferably, energy
It is enough more safely and effectively to realize elevator fall arrest.
