Elevator traction actuating device
technical field:
The utility model relates to a kind of elevator traction actuating device, belongs to elevator technology field.
background technology:
Be the particularity of the household ladder driving device structure of 2:1 due to traction ratio, need a kind of novel elevator traction drive unit, enough steady, quiet during to ensure that elevator runs, meet the needs of total, and reduce tunnel dimension as far as possible.
summary of the invention:
Technical problem to be solved in the utility model is: provide a kind of new elevator traction actuating device, should meet the household ladder Special use performance that traction ratio is 2:1, also will ensure steady safety when elevator runs.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of elevator traction actuating device, includes towing machine, is provided with towing machine adapter plate bottom described towing machine, it is characterized in that: be provided with roof beam, described roof beam is installed on hoistway overhead.
In order to reduce the vibrations of towing machine at operational process, further, between described towing machine and towing machine adapter plate, be fixedly installed cushion blocking.
In order to the speed of elevator better can be controlled, more further, described roof beam is provided with velocity limiter adapter plate, described velocity limiter adapter plate is fixedly connected with speed limiter.
Compared with prior art, usefulness of the present utility model is: provide a kind of new elevator traction actuating device, should meet the household ladder Special use performance that traction ratio is 2:1, also will can ensure steady safety when elevator runs.
