The utility model content
Problem to be solved in the utility model is for overcoming above-mentioned technological deficiency, providing a kind of simple in structure, easy to adjust, safe in operation, the machine-roomless lift that noise is low.
In order to address the above problem, the utility model by the following technical solutions:
A kind of machine-roomless lift, comprise hoistway, be connected with main girder steel in the described hoistway, be fixedly connected with towing machine on the described main girder steel, described main girder steel is connected with counterweight, car by steel rope, be fixedly connected with a bracing frame respectively on two sidewalls of described hoistway, described main girder steel is connected with bracing frame by rubber isolator.
Below be further improvement of the utility model:
Two mass are set on the described main girder steel.
Further improve:
Described counterweight comprises counterweight frame, described counterweight frame comprises two columns, the upper end of described two columns is fixedly connected with two entablatrances, the lower end of two columns is fixedly connected with cross sill, be fixedly connected with connecting panel between described two entablatrances, described connecting panel is connected with wheel bracket by center bolt, is connected with guide wheel on the described wheel bracket.
Further improve:
The position that is positioned at the guide wheel below on the described cross sill is provided with some balance iron.
Further improve:
Described car bottom is connected with the diversion sheave group.
Further improve:
The quantity of diversion sheave is three in the described diversion sheave group.
The utility model adopts such scheme, and described main girder steel is connected with bracing frame on being arranged on hoistway by rubber isolator, thereby improves isolation efficiency greatly; Being provided with of mass increased the stability that elevator moves; Wheel bracket rotates at any angle, convenient angular adjustment when counterweight frame and guide wheel are not parallel; Easier for installation; The quantity of diversion sheave is three in the diversion sheave group, the stability in the time of can effectively increasing the elevator operation.
