Abstract
A remote brake release jigger device of an elevator without a machine room is characterized in that the remote brake release jigger device comprises a traction sheave provided with a traction steel wire and an internal contracting brake, the traction sheave is further fixedly connected with a large gear, the large gear is connected with a jigger by the aid of a jigger pinion, and the remote brake release jigger device is further provided with a brake release handle for controlling opening and closing of the internal contracting brake. The jigger is driven manually, the possibility of mechanical faults is decreased, the remote brake release jigger device is high in reliability, a safety pressing plate is further arranged at the position of the control handle, the control handle can be operated by necessarily detaching the safety pressing plate, the elevator is completely disconnected with a power supply when the safety pressing plate is detached, and accidents caused by accidental power-on in a rescue process can be avoided.
Description
Technical field
The utility model relates to a kind of long-range turning gear that declutches of machine-roomless lift, belongs to elevator and makes the field.
Background technology
Along with the traction elevator application more and more widely of no machine room, the product style of machine-roomless lift is also more and more, and also has nothing in common with each other as the realization of the emergency relief device that concerns passenger's life security.But the emergency relief device of machine-roomless lift more than organic machine room-free elevator complexity many, more be difficult to design, also more be difficult to use, reliability is not high, and the core of the emergency relief device turning gear that promptly declutches.
The utility model content
The utility model is for solving the prior art problem, and a kind of long-range turning gear that declutches of safe and reliable machine-roomless lift is provided.
The technical solution of the utility model is: a kind of long-range turning gear that declutches of machine-roomless lift, it is characterized in that: comprise traction sheave, traction steel wire is arranged on the traction sheave, traction sheave also is provided with band-type brake, described traction sheave also is fixedly connected with big gear wheel, big gear wheel is connected with jiggering by the jiggering miniature gears, and the described long-range turning gear that declutches also is provided with the handle that declutches, the switch of the described handle control band-type brake that declutches.
As preferably, described handle and the jiggering handle of declutching is respectively arranged with safe pressing plate.
As preferably, the described long-range jiggering that declutches also is provided with observation window, and described observation window is made by transparent material, can see the state of kinematic motion of traction sheave and traction steel wire by observation window.
As preferably, the described long-range jiggering that declutches also is provided with free wrench, and described free wrench is connected with big gear wheel by ratchet gear, and described jiggering handle is by ratchet steel wire control free wrench.
In sum, the utlity model has following advantage:
1, drives jiggering manually, reduce the possibility that produces mechanical breakdown, the reliability height;
2, the control handle place is provided with safe pressing plate, must take off safe pressing plate and could operate, and takes off safe pressing plate then with the complete power cut-off of elevator, unexpected incoming call can not occur and cause accident in the assurance rescue process.
Description of drawings
Fig. 1 is the utility model overall structure scheme drawing;
