Description
Technical field
Declutched technical field, more particularly to a kind of elevator brake brake-releasing gear the present invention relates to elevator.
Background technology
At present, machine-roomless lift development is very swift and violent, with machine-roomless lift further genralrlization application, in the market it is inorganic
Machine room-free elevator product demand also increasingly increases, but the oppressive particularity brought by its design feature of rescuing of machine-roomless lift turns into one
Individual very important the problem of, existing machine-roomless elevator mainframe is arranged in hoistway, and people are equally straight without the organic machine room-free elevator of the image of Buddha
Connect and host service function is declutched, it is necessary to be operated outside hoistway to brake-releasing gear.Current machine-roomless lift is usually in well
Electric switch is operated to declutch by electrical means outside road, but the frequent electric brake releasing caused by band-type brake coil and terminal block failure of elevator
The problem of failure, easily it is out of order, it is impossible to ensure the safety of personnel.
The content of the invention
It is an object of the invention to provide a kind of elevator brake brake-releasing gear, brake-releasing gear can be avoided because of electric fault
It is the problem of failure, safe and reliable, and the synchronism that two brakes declutch is high.
To realize the purpose of the present invention, adopt the technical scheme that：
A kind of elevator brake brake-releasing gear, including the first brake being symmetricly set on elevator main and the second braking
Device, the first bearing and the second bearing, its also include tricing line, the operating mechanism that declutches outside the well for tensing or loosening tricing line,
First pull bar and the second pull bar arranged in a crossed manner, first pull bar one end is rotatably connected with the first bearing, and the other end is connected with cunning
Wheel, the first pull bar is provided with loose slot, and one end of the second pull bar is flexibly connected with the second bearing, and the other end is through loose slot with controlling
One end connection of rope, the other end of tricing line bypasses pulley and is connected with the operating mechanism that declutched outside well, the first brake and the second system
Dynamic device is connected with the middle part of the first pull bar and in the middle part of the second pull bar respectively.
When elevator, which breaks down, to be declutched with elevator brake brake-releasing gear, by being declutched outside well, operating mechanism is drawn
Tight tricing line, is linked pulley using tricing line, drive the first pull bar and the second pull bar rotating around the first bearing and the second bearing to
It is upper to rotate, while lifting the first brake and second brake upwards, make the brake shoe of the first brake and second brake with
The braked wheel of main frame is disengaged, and reaches the purpose declutched, lift car is smoothly moved under gravity；Unclamp operation of being declutched outside well
Mechanism, loosens tricing line, and brake shoe and braked wheel locking again, car are immovable.Elevator brake brake-releasing gear is used
Mechanical system is declutched, can avoid brake-releasing gear because electric fault fail the problem of, it is safe and reliable.And first pull bar and
Two pull bars are arranged in a crossed manner, tense tricing line after, the first pull bar and the second pull bar can be driven to be rotated up simultaneously, the first brake and
The synchronism that second brake declutches is high, and brake force is stable, and requirements of installation space is small.
Technical scheme is further illustrated below：
It is further that elevator brake brake-releasing gear also includes what is be connected with the one end of the second pull bar away from the second bearing
