The long-range device that declutches of a kind of elevator emergency
The utility model relates to the long-range device that declutches of a kind of elevator emergency, does not need emergency source of electrical power when being applicable to the machine-roomless lift dead electricity, can manually declutch, implements promptly to rescue, guarantee the elevator reliability of operation at a distance.
The elevator of prior art mostly is organic machine room-free elevator greatly, when emergency ratings such as elevator has a power failure, maintenance, when control system can not declutch because of dead electricity, but because machine room is arranged, people can realize manually declutching in machine room and make lift car carry out upper and lower moving under the effect of turning gear, realize the purpose of interior personnel of rescue sedan-chair and convenient maintenance.In recent years, along with developing rapidly of elevator technology, machine-roomless lift little by little replaces original machine room elevator just as the technology main flow.But because of the main frame (towing machine) of machine-roomless lift generally be mounted in hoistway on put/top, when emergency ratings such as appearance power failure or maintenance, control system just can't declutch when no emergency source of electrical power, and organic machine room-free elevator device that declutches of reality can not be used for machine-roomless lift.People must consider to invent a kind of energy distance control elevator machine brake, and its enforcement is manually declutched to reach rescue by the purpose of pass personnel or maintenance.
The declutch patent of aspect of Chinese patent by retrieval, relevant elevator only has two pieces, and structure that they and the utility model provide and operating mode are all inequality.Referring to the patent No.: 00242638.2; 03256409.0.In sum, prior art none flexibly reliable again, long-range device that declutches that can be widely used in gearless machine or geared machine drg simple in structure, easy to install still.
Summary of the invention
The utility model provides a kind of elevator emergency the long-range device that declutches, and it has flexibly reliable again, the desirable long-range control system that declutches that can be widely used in the gearless machine or the geared machine drg of machine-roomless lift simple in structure, easy to install; But it can not need the emergency source of electrical power remote manual to declutch, implement promptly to rescue, guarantee the elevator reliability of operation when the elevator dead electricity.
Concrete technical scheme of the present utility model is as follows: the long-range device that declutches of a kind of elevator emergency, be that the former integral type device that declutches is divided into two parts, promptly by control mechanism and brake-loosing mechanism, and interconnect to pin down through one wire drawing/steel wire cable and realize the manually long-range purpose that declutches; On solid electrical control cubicles, ground or other buildings outside elevator hoistways of control mechanism dress; Brake-loosing mechanism is divided into two two kinds of drg brake-loosing mechanism and folding brake brake-loosing mechanisms that push away according to real drg classification, and they are respectively installed on brake support frame or the towing machine web; One end of wire drawing  and the pipe link  in the control mechanism connect solid; The spanner pipe link  of the other end of wire drawing  and brake-loosing mechanism is fixing; Wherein: control mechanism is made of the removable handle that declutches , pipe link , overcoat , pin , locating dowel pin , base , semi-disc lever  and a wire drawing  that is " Z " shape; Wherein: brake-loosing mechanism is made of the fulcrum  of spanner , pipe link , fixed jacket .The long-range device that declutches of above-mentioned a kind of elevator emergency, wherein the pipe link in the control mechanism  dress is solid on semi-disc lever , sells  again semi-disc lever  is installed on the base ; Locating dowel pin  is installed in the dowel hole of base  and semi-disc lever .Spanner in the brake-loosing mechanism wherein  is contained in drg and declutches on six prisms, and spanner  can be around six prismatic rotations; Pipe link  is fixed in the other end mounting hole of spanner , and the other end of wire drawing  and pipe link  are fixing; Wherein: two drgs that push away are installed on the brake support frame; Folding brake is installed on the towing machine web.

The specific embodiment
Further describe working principle of design of the present utility model and embodiment below in conjunction with accompanying drawing.
Design of the present utility model adopted 1, with former integral type declutch device be designed to split type two independent install can interconnect by one wire drawing/steel wire cable again pin down, thereby realized the manual long-range purpose that declutches simply, emergency relief and repair and maintenance when having guaranteed the machine-roomless lift generation outage of inhead type (main frame) and not had emergency source of electrical power.2, the handle that declutches of control mechanism generally can adopt the cylinder type tube bending to become " Z " shape, does not take up space after making rapid operation save time, be convenient to remove, take in.3, semi-disc lever  drives wire drawing/steel wire cable, make the power of declutching and the displacement of declutching big, be the once linear functional relation with the rotation of the handle that declutches.
The Unit Installation that declutches in the utility model order is as follows: earlier spanner  is installed on the former interface that manually declutches of traction machine brake, load onto spanner pipe link  then in the installation site of spanner, one end of wire drawing  is fixed on the spanner pipe link , fulcrum  is installed on the casing, then overcoat  is fixed on the fulcrum , brake-loosing mechanism partly installs like this.
The assembling of control mechanism as shown in Figure 1 in the utility model: the other end and the pipe link  with wire drawing  connects solid earlier, pipe link  is installed on the semi-disc lever , then semi-disc lever  is installed on the base  with pin , after base  fixed, overcoat  in addition end be fixed on the base .For the factor that prevents to prevent takes place, drive semi-disc lever  after all installing with upper-part, locating dowel pin  is installed in the dowel hole of base  and semi-disc lever .When need rescue or maintenance, should at first draw locating dowel pin , spanner  is installed on the pipe link , the pin-and-hole that requires the pin-and-hole of spanner  and pipe link  simultaneously is collinear, insert locating dowel pin  (preventing the same pipe link of spanner   slippage in implementing the process that declutches), can implement the remote manual control of declutching.
The utility model remote manual manner of execution that declutches is: when spanner  when pin  rotates to an angle α, wire drawing  will be along the U type groove elongation (overcoat  is fixing can't to be moved) of semi-disc lever, the play motion of control end wire drawing  reduces, wire drawing  can be considered rigid body when moving vertically, the play motion of the wire drawing of the other end  will reduce gradually, when power reaches required value, order about spanner  and rotate, satisfy the purpose that declutches when reaching certain stroke around the fulcrum on the drg.(or under setting stick wheel drive) cab moves up and down under the gravitational difference effect of counterweight and cab, when arriving the desired position, cancellation is added in the power of the handle that declutches, effect lower ejector lever , wire drawing , the spanner that declutches  in retracing spring  and drg band-type brake power are returned to previous status, release, the cab stop motion.
This shows, position and the very convenient remote manual effect of easily finishing machine-roomless lift of declutching that the utility model can allow the people stand in a safety, become clear, it can extensively be useful in gearless or geared machine, be a kind of desirable machine-roomless lift remote manual of the safe and reliable practicality device that declutches, have that cost is low, flexible for installation, easy to use, low cost and other advantages.
