The utility model adopts structural form of chain drive, when emergency power supply is unavailable, traction sheave may be rotated by rotating barring handwheel, so as to realize up, down running of the car by manpower. The utility model has novel unique structure, may be installed and used practically, flexibly and conveniently, requires small operating force during barring, has the advantages of low cost and good safety performance, is a practical manual barring device.
Description
Technical field
The utility model relates to a kind of elevator emergency device, and this device is to be applied on the anodontia towing machine, is used for the hand turning gear of mobile car under emergency or when maintenance is installed.
Background technology
When the elevator operation is broken down or had a power failure, generally adopt backup power or manual jiggering mode to make car move to correct position.Use the backup power cost too high, and when the backup power et out of order, still can't use.And along with the development of elevator technology, anodontia towing machine will progressively be substituted with the tooth towing machine, become the main flow of elevator hoist, and be directed to tooth towing machine design-calculated hand turning gear has not had the ample scope for abilities thereupon yet.So it is just very necessary to design the hand turning gear that is suitable for anodontia towing machine.
Chinese patent by retrieval, search the patent of relevant anodontia towing machine, wherein: " elevator with the hand turning gear of anodontia towing machine ", the patent No.: 200420071131.0, this patent is to utilize sprocket wheel as driving device, but fail to consider two aspect problems, the one, handwheel is not provided with stop motion mechanism, be difficult to like this finish chain is installed to work fixing on the sprocket wheel, and before unclamping band-type brake, can't know the force direction that is subjected to of traction sheave at all, the operator is difficult to the correct operation hand turning gear of safety after unclamping band-type brake like this.The 2nd, the basic out of reach request of national standard in operating effort aspect.Stipulate according to standard GB 7588-1995 " elevator manufacturing and installation safety standard ": have the car of nominal payload if move up, action required power can not be greater than 400N.Since national Specification the transmitting ratio i between two sprocket wheels of chain sprocket drive general≤7, be up to 10, that is to say single dependence chain-driving, it is stressed to be that the one-level transmission reduces, operating effort can only be reduced to wheel along about 1/7 of power, and actual satisfying under the condition of national standard, the wheel of traction sheave along power generally all more than 4000N, so this device can not satisfy the requirement of national standard to operating effort when practical application.
Also retrieve two relevant patents in addition: " hand turning gear of gearless machine ", the patent No.: 02217935.6 and " hand turning gear of anodontia towing machine ", the patent No.: 00241548.8, the also big problem of ubiquity operating effort, transmission reduces operating effort because the hand turning gear of these anodontia towing machines all uses the gear one-level.Do not use the reason of speed reduction gearing to be, these hand turning gears all be direct mount on the fuselage of towing machine because the relation of structure and space and installation has limited the utilization of speed reduction gearing, operating effort has substantially exceeded 400N like this.In addition, the hand turning gear direct mount is not only installed inconvenience on the fuselage of towing machine, and influence the towing machine overall appearance, also increased cost.
Summary of the invention
Design original intention of the present utility model is to address the above problem, and provides a kind of real jiggering power little, easy for installation, and processing is simple, the hand turning gear of safety of operation, easy anodontia towing machine.
Function of the present utility model is achieved in that handwheel is coaxial and has a miniature gears that miniature gears and a big gear wheel are meshing with each other, and play deceleration effort.Big gear wheel is coaxial to have a minor sprocket, and the traction sheave at elevator main tightens a hinge wheel simultaneously, and minor sprocket links to each other by chain with hinge wheel, a gearing, thus reach the purpose of manual jiggering.
Be equipped with lock pin aperture on big gear wheel and the jiggering support,, just can handwheel and each gear, sprocket wheel remained static, be convenient to install as long as stop pin is passed pin-and-hole.When unclamping band-type brake, do not extract earlier stop pin, wheel can drive each wheel and handwheel has a fine motion along power, at this moment just can correctly judge the action direction of wheel along power, extract stop pin again after holding handwheel, just can carry out manual jiggering along correct direction.
The utility model has adopted the secondary type of drive, and the first order is a chain sprocket drive, and the second stage is gear transmission, all play the effect that subtracts moment, the transmitting ratio of entire mechanism has reached 22.5, has reduced the jiggering power of manual jiggering greatly, meets the requirement of national standard to jiggering power size fully.
Two installation shaft that wherein have handwheel, speed reduction gearing and minor sprocket all are installed on the same jiggering support, compact conformation has a style of one's own like this, as long as find two relative positions between the sprocket wheel during installation accurately, the jiggering support is riveted on the frame of carrying towing machine, can finishes installation.Mounting means can unload this covering device under the situation of the normal operation of elevator so easily, also can only unload chain.Because the utility model is not to be directly connected on the towing machine fuselage, to the not infringement of structure of towing machine itself, it is time saving and energy saving, easy to operate to install, and range of use is big.The jiggering support can be fixed on any side frame of towing machine rope sheave both sides, and is very little to the requirement of erecting stage.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further
Figure is a structural representation of the present utility model.
Wherein: 1. 4. 5. 6. minor sprockets of handwheel 2. miniature gearss, 3. jiggering supports, 7. big gear wheels, 8. stop pins, 9. chains, 10. hinge wheels, 11. towing machine rope sheaves.
The specific embodiment
Handwheel 1 links to each other with miniature gears 2 by axle 4, and miniature gears 2 is meshing with each other with big gear wheel 7, a deceleration effort.Big gear wheel 7 links to each other with minor sprocket 6 by axle 5, and axle 4 is fixed on the jiggering support 3 by bearing installation with spools 5.Towing machine rope sheave 11 at elevator tightens a hinge wheel 10, and minor sprocket 6 links to each other by chain 9 with hinge wheel 10, plays gearing.Stop pin 8 is inserted in the stop pin through hole of big gear wheel and jiggering support, when mounted with jiggering before start-stop action usefulness, and assist operator is correctly judged the direction of wheel along power when unclamping band-type brake.After preparation work is carried out, extract stop pin 8, rotate handwheel, thereby realize manually finishing the upper and lower motion of car.
