Through the test, the effect ideal.

Description

Elevator speed limiter wire rope clamps special locking pliers

Technical field

The utility model belongs to lift facility inspection steel rope clamping technical field, is particularly useful for the field of elevator governor field-checking, maintaining and rapid simulated test.Such as during elevator governor inspection, the folder becket bridle that steel rope separates from elevator governor is saved, and other relate to wire rope tightening, fixing field.

Background technology

Along with the quickening of Urbanization in China, elevator quantity gets more and more, and elevator, as vertical manned transport equipment, once elevator is in the situations such as brake failure, wire cable rupture or braking force are not enough, may causes car speeding to fall, cause casualties.The effect of speed limiter system be just can when above-mentioned situation occurs stop car, thus avoid the generation of safety misadventure, therefore speed limiter system is the indispensable important component part of elevator safety operation.Velocity limiter is in process of production through type test, in-use performance can be guaranteed under normal circumstances, but after elevator place in operation, velocity limiter may cause impaired performance even malfunctioning due to reasons such as corrosions, therefore must carry out periodical survey to the speed limiter system of elevator." elevator surveillance inspection and periodical survey rule " regulation, when elevator uses 2 years or occurs that velocity limiter is abnormal, should have tool elevator to check the mechanism of qualification to carry out velocity limiter inspection, to ensure that velocity limiter action is normal, ensure the safe operation of elevator.

China, in the eighties in last century, is just classified as " special equipment " and is carried out safety supervision management.And in the process of elevator governor field-checking, must in advance the steel rope of elevator governor and governor sheave be departed from, just can carry out inspection work below.

At present common on the market elevator speed limiter wire rope typically have a diameter from φ 8 or φ 6mm, at home market do not have unit clamp, be generally used in the locking pliers bought on the market, but its jaw shapes is sharper, each use all has and causes steel rope by pinch off in varying degrees, crushes, squeezes the phenomenons such as flat, sometimes also there is the unsafe condition skidded, poor reliability.Some Inspection Units even need the velocity limiter overall pulling down all elevators, and deliver to formulation place testing platform and detect, then transport go back to use scene and reinstall, not only work efficiency is very low, also delays elevator and uses.

Summary of the invention

The purpose of this utility model is for the indeterminable problems of above-mentioned background technology, design a kind of special locking pliers of elevator speed limiter wire rope of special shape jaw, cause in clamp rope slack rope process steel rope to hinder rope energetically in order to solve routine, skid, the problem such as dangerous, unreliable, inefficiency.

The utility model is specially for φ 8 or φ 6mm Wire Rope Design, and technical scheme adopted to achieve these goals is as follows:

Elevator speed limiter wire rope clamps special locking pliers, primarily of binding clip and clamp handle composition; Described binding clip is made up of upper clamp 1 and lower clamp 2, and described upper clamp 1 is made up of jaw 9 and spacing dog 10; Described lower clamp 2 is made up of jaw 13 and dog catching groove 14; Upper clamp 1 is connected by bearing pin 16 with lower clamp 2; Be provided with 4 dogs 10 near upper jaw 12, lower clamp should have dog catching groove 14 mutually near jaw place, and dog 10 and dog catching groove 14 fit tightly and make can entirely surround clamping steel wire rope in clamp clamping process, and upper clamp 1 and lower clamp 2 engage each other.

Design in a clamping process realize complete surrounding, inside face is without corner angle and have the binding clip of support function, other parts are made up of a locking pliers, the circular arc of composition jaw is applicable to the steel rope of more than 4mm below 10mm, this makes for the steel rope of 2 kinds of the most frequently used diameter 6mm and 8mm of elevator governor, with solve elevator governor inspection steel rope clamping process wound rope, skid and the problem of space interference, and simplify the operation, increase work efficiency (for the steel rope of other diameters, in like manner can making by different specifications).

The beneficial effects of the utility model are that this jaw adopts full enclosed clamped design, and can be used for the elevator speed limiter wire rope of diameter 6mm, 8mm, jaw inside face is bright and clean without corner angle, even if step up steel rope also zero damage.Tighten in cylindrical in two panels jaw tightening process, after its clamping, the unlikely steel rope that causes is pressed from both sides flat distortion, binding clip thickness 18mm increases area of contact, effectively prevent skidding, male-female engagement is adopted when associated jaw portion closes, fit tightly, clamp handle part adopts existing locking pliers handle self-locking mechanism on the market; The size of its gripping power can regulate as required.This binding clip have certain thickness in order to support and spacing, caliper can be supported on the hole of the various different size of velocity limiter, avoid space interference, make the position that clamping system energy secure support is being determined; The conventional difficulties that this locking pliers solves elevator governor field inspection process folder rope wound rope and skids.The blank of home market wire rope nondestructive clamp device filled up by this locking pliers; Through onsite application, this device is simple to operate, safe and reliable, substantially increases work efficiency, satisfactory for result.Utilize this device, rapid simulated test can be carried out to elevator governor; Fast slack rope operation is carried out to elevator governor, be the periodical survey of elevator Inspection Unit, the self-inspection of elevator maintenance maintenance unit, greatly increase work efficiency, provide a great convenience; Popularizing application prospect is wide.

Detailed description of the invention

This device is utilized to carry out the operation of clamping slack rope to elevator governor field inspection process: above the steel rope hole of elevator governor expansion tightening wheel side, use these steel rope special vice clamping steel wire rope concrete operations as follows: according to the upper clamp 1 of diameter adjustment and lower clamp 2 opening angle of steel rope 9, then steel rope steel clamp being entered upper clamp 1 has in the jaw of dog 10 side, parallelly be placed on above hole, regulate lock bolt 4, to hold with a firm grip fixed caliper 3 and moving caliper 6, closed upper clamp 1 and lower clamp 2, clamping speed limit steel rope 9, the up a bit of stroke of car crawl is made with inspection speed, just can carry out de-rop exercise work very like a cork, by rope or waste leading wire section, speed limit rope is gently tied to side if desired, just (can note: during speed limit rope reset operation velocity limiter work of testing, for avoiding gang switch action below, car crawl should be made).Stir pine pincers ripping bar 5 after being verified, get final product easy removal.
