Description
Invention field
The utility model relates to the detection that is used for elevator up-down hypervelocity fault and the technical field of safety devices of correction, specifically relates to a kind of bidirectional speed limiter for elevator.
Technical background
Traditional elevator governor is descending unidirectional speed limit, for improving the safety of operation, need up-down bidirectional is all carried out speed limit, be head it off, China's patent of invention has proposed " bidirectional speed limiter for elevator " (patent No.: 00105650.6), it is improved on traditional centrifugal block for clutch use velocity limiter basis, its brake equipment has a rope sheave, there are two pairs of rope-clamping plierses at the governor rope two ends, moving rope-clamping pliers is connected with the two ends of a compression spring, the lagging hinge linkage on moving rope-clamping pliers end and the friction wheel; Brake equipment also comprises the friction wheel coaxial with rope sheave; Flip flop equipment comprises that two fly iron, and two fly iron becomes parallelogram with two rod hinge connections, is with centrifugal spring on two connecting rods and is connected with shift fork, flies the moving shift fork that makes of Railway transportation and triggers friction shoe and friction wheel locking; Fly iron and can drive the triggering micro-switch that re-packs; This bidirectional speed limiter for elevator has solved the descending slide car of elevator, the speed limit problem of up slide car, free fall preferably; But this velocity limiter also exists following problems: the one, and processed complex, difficulty is big; The 2nd, because of the wearing and tearing of friction shoe, often occur not contacting when friction shoe should trigger; The 3rd, the action of the moving rope-clamping pliers of glancing impact is pressed firmly by connecting rod, and it is stiff to move, back two reliability that reduce elevator safety operation.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art, provides a kind of simple in structure, and Installation and Debugging are convenient, a kind of bidirectional speed limiter for elevator that good manufacturability and reliability are high.
For achieving the above object, the technical solution adopted in the utility model is: a kind of bidirectional speed limiter for elevator, form by rack-mounted rope sheave assembly, two-way rope grip mechanism, two-way overspeed switch assembly, reset detection switch and the parts such as two-way ratchet assembly that are hinged on the rope sheave; Its main shaft of the rope sheave of said rope sheave assembly is fixed on the frame, be connected with rope sheave by antifriction-bearing box, on two symmetric points of a pair of spoke of rope sheave, be hinged with the centrifugal block for clutch use of two symmetries respectively by pivot pin, two centrifugal block for clutch use connect with connecting rod link, on another spoke of rope sheave, also be hinged with a governing spring device, the other end of this device and centrifugal block for clutch use arm are hinged, a screw with square head is fixed in this centrifugal block for clutch use end, on the hinge-point of itself and rope sheave, also be hinged with a two-way ratchet, and on the rope sheave web, fix a trip(ping) bar; Said two-way ratchet assembly is made up of two-way ratchet that is fixed together and two-way shift fork, its ratchet matches with ratchet, and and rope sheave be concentric, be enclosed within on the rope sheave main shaft, at ratchet and the superimposed place of two-way shift fork one circular arc fluting is arranged, passing the lock pin that is fixed on the frame, in the middle of two-way shift fork, a waist hole is arranged, be installed on the frame riser the steel ball that ejects by spring in the locating bush by this location, waist hole; Said two-way rope grip mechanism is made up of left and right moving rope-clamping pliers piece and the spring installation, left and right sides suspension hook, the quiet pincers piece in the left and right sides etc. that connect this two pincers piece; The eccentrically weighted shaft and the frame of its moving rope-clamping pliers piece are hinged, and eccentrically weighted shaft has the self-locking clamping action, also are fixed with the hook spare that switch re-packs and contact with left and right sides suspension hook respectively on left and right moving pincers piece; The spring shaft two ends of spring installation are fixed on the left and right moving pincers piece, and the centre is connected with one group of belleville spring by axle sleeve; The quiet pincers piece in its left and right sides is separately fixed on the two ends of gantry base; Left and right sides suspension hook fixes with frame by the suspension hook axle and matches with two-way shift fork; On frame, also be fixed with two-way overspeed switch and left and right sides reset detection switch.
Working process of the present utility model is such: when velocity limiter during in normal operation, speed limiter wire rope rotates along with the up-downgoing of lift car drives the governor sheave both forward and reverse directions.When elevator overspeed, along with the increase (increasing to desired location) of velocity limiter centrifugal block for clutch use radius of rotation, the screw with square head on the centrifugal block for clutch use makes two-way overspeed switch action, thereby makes the safety return circuit outage of elevator, reaches the purpose that stops elevator to continue operation.If two-way overspeed switch fails to stop elevator to continue operation, when elevator speed reaches the mechanical action speed of velocity limiter setting, the centrifugal block for clutch use arm of velocity limiter makes the trip(ping) bar tripping operation, this moment, two-way ratchet broke off relations left side pincers piece or right pincers piece by two-way ratchet, two-way shift fork, left suspension hook or right suspension hook, left side pincers piece or right pincers piece fall under the effect of gravity, along with the continuation operation speed limiter wire rope of elevator is clamped between left side pincers piece or right pincers piece and the quiet pincers piece.Under the effect of steel rope and pincers interblock friction force, be installed in the safety tongs action on the lift car, the deceleration of elevator stop.When velocity limiter left side pincers piece or right pincers piece fall, be installed in switch on left side pincers piece or the right pincers piece and re-pack and make the reset detection switch motion, this switch does not play the purpose that stops the elevator operation before left side pincers piece or right pincers piece reset.
A kind of bidirectional speed limiter for elevator of the present utility model is big without difficulty of processing, friction wheel that safety factor is not high and friction shoe are as trigger mechanism, but adopted the trigger mechanism of two-way ratchet, two-way ratchet, two-way shift fork etc., so reliability height, Installation and Debugging are convenient, have favorable manufacturability simultaneously; Simple in structure as the velocity limiter of the same type of trigger mechanism with two ratchets, two ratchets than need, Installation and Debugging are convenient; The two-way rope grip mechanism of this velocity limiter is on the basis of Wedge-type rope grip mechanism, has increased a pair of rope-clamping pliers, so it has the advantage of voussoir clamping-rope type rope grip mechanism, and has two-way folder rope function; Simultaneously, the two-way rope grip mechanism of this velocity limiter has adopted disk spring, because the disk spring volume is little, can conserve space helps the realization of this structure, also can require superimposed, involutory, the compound different spring assembly that goes out according to the folder rope power of different range.
