Description

Machine-roomless lift
Technical field
The utility model belongs to the elevator field, is specifically related to a kind of machine-roomless lift.
Background technology
No machine room developed so far from the early 1990s in last century, and elevator technology is now quite ripe, and the main layout pattern that does not have machine room at present is that main frame is placed hoistway top, but installs, overhauls and maintain cumbersome; Also have part producer with towing machine as for hoistway bottom, also need by the hoistway bottom around top but steel cable is final to hoistway, steel cable length is longer, cost is higher, the while needs compensated chain for big lifting height, the also corresponding increase of cost.In a word, existing machine-roomless lift or installation, maintenance inconvenience, or need the installing compensated chain, the cost height needs to do further the improvement.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, and a kind of machine-roomless lift is provided, and this elevator installation, easy maintenance, cost are low.
The utility model is achieved through the following technical solutions:
A kind of machine-roomless lift comprises hoistway, top erecting by overhang, counterweight, car, towing machine and steel cable, and towing machine is provided with traction sheave, and the top erecting by overhang is located at the top of hoistway, and car is located in the hoistway; This elevator also comprises diversion sheave, described steel cable comprises dragged wire-rope and hangs steel cable, towing machine is installed on the bottom of hoistway, and the top of counterweight and car is suspended on the erecting by overhang of top by suspension steel cable, diversion sheave, and the bottom of counterweight and car is connected with traction sheave by dragged wire-rope.
In the utility model, towing machine is located at the bottom of hoistway, installs and maintain very convenient, described steel cable is divided into upper and lower two sections, and the length of steel cable is shortened, and does not also need compensated chain is set again, and cost is low.
Further structure of the present utility model is:
Described diversion sheave is at least three, be located at described counterweight top, described top erecting by overhang below, described car top respectively, after described suspension steel cable was walked around the diversion sheave of described counterweight top, described top erecting by overhang below, described car top successively, its two ends were connected on the erecting by overhang of described top.After adopting this structure, can avoid movable parts being set the safety when the raising maintainer keeps in repair at the top of hoistway.
Described diversion sheave is four, and wherein two diversion sheaves are located at the both sides of described car top respectively, and are more steady during cage operation after car top is provided with two diversion sheaves, the traveling comfort height.
One end of described dragged wire-rope is connected with described counterweight, and the other end is connected with described car after walking around described traction sheave.
This elevator also includes the adjustment spring, and the end of described traction is connected with described counterweight or car by adjusting spring.Can regulate tension force size between dragged wire-rope and the traction sheave by adjusting spring, to guarantee the dragged wire-rope effect of traction sheave.
Bottom at described hoistway also is provided with the guiding tension wheel, and described dragged wire-rope is walked around this guiding tension wheel simultaneously, can adjust tension force between dragged wire-rope and the traction sheave by the guiding tension wheel, also can adjust the cornerite of traction sheave.
Described guiding tension wheel is provided with regulating spring, by regulating spring also can be to the tension force between dragged wire-rope and the traction sheave, adjust.
To sum up, the utility model has the advantages that:
1, traction sheave is located at the bottom of hoistway, is installed and easy maintenance;
2, steel cable length is shorter, also need not add compensated chain, and cost is lower.
