Abstract
The utility model discloses an underneath type elevator without a machine room, which comprises a lift car positioned in a lift shaft and a counterweight matched with the lift car, and further comprises a tractor driving the lift car to ascend or descend through a steel wire rope; a left fixing end and a right fixing end, which are used for fixing the steel wire rope, are arranged at the top of the lift shaft; a counterweight guide wheel and a lift car guide wheel are arranged between the two fixing ends; the tractor is positioned at the bottom of the lift shaft; one end of the steel wire rope is connected to the right fixing end, and then is connected to the left fixing end after bypassing a lift car wheel at the bottom of the lift car, the lift car guide wheel, a traction wheel of the tractor and the counterweight guide wheel in sequence; the counterweight is suspended on a section of steel wire rope between the counterweight guide wheel and the lift fixing end. The underneath type elevator without the machine room has the advantages that the mounting and the maintaining are convenient, the rescue is convenient, high temperature resistance and noise insulation are achieved, the service life is long, and the top height is reduced.
Description
Technical field
The utility model relates to a kind of elevator, specifically a kind of bottom elevator without cabin.
Background technology
The towing machine of tradition machine-roomless lift all is mounted in the top of elevator hoistways usually, be provided with simultaneously car and counterweight in elevator hoistways, during installation, steel rope is walked around the traction sheave of walking around again towing machine behind car bottom, and then from the roller lower end is walked around and steel rope is fixed, make thus towing machine drive traction sheave and make the car lifting, adopt existing this overhead type elevator without machine room, although make the route that detours of steel rope shorter, but have following defective:
1, when elevator breaks down, the maintainer need to arrive the top of elevator hoistways and keep in repair, and has increased thus the maintenance difficulty of maintainer to elevator;
2, when elevator causes elevator to close the accident such as people due to reasons such as power failures, be difficult to trapped personnel is succoured;
3, the towing machine top that is positioned at elevator hoistways can make sunlight shine directly on towing machine, thereby can make towing machine the intensification that causes due to solar radiation occur, not only easily causes the frequent generation of elevator faults, more can make the service life that shortens towing machine;
4, traditional inhead type towing machine is positioned at by attic resident family bedroom, and the normal operation meeting of towing machine causes noise jamming to attic resident family;
5, owing to towing machine being placed in the building top layer, increased the height of building, traditional machine-roomless lift headroom height has not only increased the hoistway cost thus greater than more than 4500mm, also can be subject to the limitation in height of building in city planning.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of not only installation and maintenance and rescue is convenient, and can reduce the building roof layer height, extends the towing machine bottom elevator without cabin in service life.
in order to solve the problems of the technologies described above, bottom elevator without cabin of the present utility model, comprise the car that is positioned at elevator hoistways and the counterweight that is complementary with car, also comprise the towing machine by the lifting of Steel rope drive car, the top of elevator hoistways is provided with two and is used for the fixedly left and right fixed end of steel rope, be provided with counterweight track adjusting wheel and car track adjusting wheel between two fixed ends, towing machine is positioned at the bottom of elevator hoistways, after being connected on right fixed end, one end of steel rope walks around successively the car wheel of car bottom, the car track adjusting wheel, the traction sheave of towing machine, be connected on left fixed end after the counterweight track adjusting wheel, counterweight is by being suspended on roller on one section steel rope between counterweight track adjusting wheel and left fixed end.
The height of described elevator hoistways is more than 3800mm.
The utility model has the advantage of:
1, installation and maintenance are convenient: towing machine is arranged on the bottom of elevator hoistways, not only flexible and convenient to use, when elevator broke down, the maintainer just can keep in repair in the bottom of elevator hoistways, had reduced thus the maintenance difficulty of maintainer to elevator.
2, convenient rescue: when causing the accident such as elevator people from pass due to reasons such as power failure when elevator, the rescue personnel can carry out jiggering to towing machine easily puts the people;
3, anti-high temperature, long service life: towing machine is positioned at the bottom of elevator hoistways, avoided sunlight to shine directly on towing machine, the intensification that causes due to solar radiation can not appear in the towing machine temperature, has reduced the frequent generation of elevator faults, but extends the service life of towing machine;
4, noise-proofing: the noise that the normal operation of towing machine and control housing contactless switch send can not produce noise jamming to resident family;
5, reduce headroom height: owing to towing machine being placed in the bottom of elevator hoistways, having reduced the height of building, can be more than 3800 with the machine-roomless lift headroom height, has not only reduced thus the hoistway cost, also can not be subject to the limitation in height of building in city planning.
Description of drawings
Fig. 1 is the structural representation of the utility model bottom elevator without cabin.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, bottom elevator without cabin of the present utility model is described in further detail.
as shown in the figure, bottom elevator without cabin of the present utility model, comprise the car 2 that is positioned at elevator hoistways 1 and the counterweight 4 that is complementary with car, also comprise the towing machine that drives car 2 liftings by steel rope 3, the top of elevator hoistways 1 is provided with two and is used for fixedly left fixed end and the right fixed end of steel rope 3, be provided with counterweight track adjusting wheel 6 and car track adjusting wheel 7 between left fixed end and right fixed end, towing machine is positioned at the bottom of elevator hoistways, after being connected on right fixed end, one end of steel rope 3 walks around successively the car wheel 8 of car 2 bottoms, car track adjusting wheel 7, the traction sheave 5 of towing machine, be connected on left fixed end after counterweight track adjusting wheel 6, counterweight 4 is by being suspended on roller 9 on one section steel rope between counterweight track adjusting wheel 6 and left fixed end, the height of elevator hoistways 1 is more than 3800mm.
Bottom that further can elevator hoistways 1 is set to a height lower than the melt pit on (garage) ground, be arranged on towing machine in melt pit and make it higher than (garage) ground, the maintainer is keeped in repair in melt pit, easy to maintenance.
