Abstract
The utility model discloses an elevator disk machine with a synchronous motor as a tractor, and comprises a large diameter gear disk which is fixed on the output shaft of the tractor ,a gear shaft seat which is fixed on the tractor, a gear shaft which can covered on the gear shaft seat, a hand wheel of the disk machine which is arranged on the gear shaft; the gear shaft is provided with a small diameter gear disk which is meshed with the large gear disk. The utility model is a manual disk machine with low cost and high security.
Description
Technical field
The utility model relates to a kind of lift appliance, and it is to be applied in the turning gear that uses on the elevator that towing machine is a synchronous dynamo, under emergency operation or Installation and Debugging operating mode.
Background technology
The turning gear of elevator is an emergency operation mechanism when being mainly used in Lift out of order, according to standard GB 7588-1995 " elevator manufacturing with safety standard is installed " regulation; The car that has nominal payload if move up, required operating effort is not more than 400N, and the elevator drive main frame is installed and is established the manual emergency handling device, so that use level and smooth handwheel car is moved to a stop; If action required power is greater than 400N, the machine room planted agent is provided with a corresponding electrically-operated arrangement.Because the electrically-operated arrangement price is higher, and consider the elevator safety when improving the building electric fault, employing electrically-operated arrangement that should be the least possible, and adopt the mechanical device of realizing jiggering by the manual operation handwheel.
From present elevator technology present situation, adopting synchronous dynamo is a direction of elevator Future Development as towing machine.The change of towing machine must cause the variation of other corresponding component of elevator, device for emergency operation---turning gear also will change for it.
Because the asynchronous dynamo that original towing machine uses generally is furnished with drop-gear box, as long as can realize jiggering with less power rotary electric machine axle.And synchronous dynamo does not have speed reduction gearing, if adopt original barring mechanism, action required power will improve greatly, so present hand turning gear can not satisfy the requirement of national elevator standard.
Summary of the invention
The purpose of this utility model is that a kind of cost is low, safety good in order to provide, and can manually operated towing machine is the turning gear on the elevator of synchronous dynamo.
Main technical schemes of the present utility model is: this turning gear comprises the large diameter gear dish that is fixed on the synchronous dynamo output shaft, be installed in gear shaft block on the synchronous dynamo, can be sleeved on the gear wheel shaft on the gear shaft block, gear wheel shaft and handwheel fix, small-diameter gear on the gear wheel shaft is meshed with the large diameter gear dish when work, thereby realizes the jiggering action by rotating handwheel.
The big or small gear meshing of utilizing the utility model has reduced the operating effort of turning gear, its manufacture craft maturation, and cost is low, and safety is good, can satisfy the requirement of national standard about moving device for emergency operation.And the utility model and comparatively compact the combining of motor formation, save the space, be convenient to dismounting.
Description of drawings
Fig. 1 is the front view of an embodiment of the utility model;
Fig. 2 is the lateral plan of Fig. 1.
The specific embodiment
As shown in Figure 1, 2, present embodiment comprise be fixed on as the large diameter gear dish 2 on synchronous dynamo 1 output shaft of towing machine, be installed in the nonrotational part of synchronous dynamo gear shaft block 5, can be sleeved on the gear wheel shaft 3 on the gear shaft block, the small-diameter gear 6 that is fixed with handwheel 4 on the gear wheel shaft 3 and is meshed with large diameter gear dish 2.
