Description
Technical field
The utility model relates to a kind of elevator device, belongs to the elevator technology field.
Background technology
Existing elevator main, car, counterweight arrangement are as follows: main frame is installed in the top of elevator hoistways, car and counterweight are by traction steel-cable or steel band, be suspended on the traction sheave both sides of main frame, steel rope or steel band pass crosshead sheave or the sedan-chair return pulley of car, realize hard the connection at the hoistway top layer, steel rope or steel band other end are passed the counterweight wheel and are realized hard the connection at the hoistway top layer.Also having a kind of mode is that car and counterweight pass through traction steel-cable or steel band, is suspended on main frame traction sheave both sides, and steel rope or steel band two realize being connected firmly with car and counterweight respectively.This dual mode car quality and counterweight quality all are added on the traction sheave, in the traction sheave rotary course, friction force by traction sheave grooving and steel rope or traction sheave and steel band produces traction, driving car rises or descends, this arrangement has two drawbacks: the one, and steel rope or steel band rise and hang and the traction double action, to having relatively high expectations of steel rope or steel band; The 2nd, car quality and counterweight quality all are added on the traction sheave, cause the axle load of main frame very big.These two drawbacks all can cause the elevator major part life-span to descend, and overall security reduces.
Chinese patent file by retrieval, retrieve U.S. Otis company and have several about the patent of invention of elevator installation system, be called such as the ZL99803363.4 name and have the Machineroom-less elevator system that is installed in the elevator main on the lift car, or the ZL99803364.2 name is called the elevator device that has the drive motor that is positioned at the top, but the technology contents of all patents all is different with the utility model.
The utility model content
The purpose of this utility model is to provide a kind of and operates steadily, cost is low, the simple elevator device of technology, host output shaft will bear car quality and counterweight quality in the prior art to solve, cause the axle load of main frame very big, and steel rope or lower problem of steel band life-span.By suspension and the type of drive of improving current lift car and counterweight, to reach the purpose of this utility model, technical scheme is as follows:
A kind of elevator device comprises main frame 9, car 2, tensioning member, assembly pulley and counterweight 7, and wherein, main frame 9 is fixed on hoistway bottom 11; Assembly pulley comprises at least one group of car pulley 3, at least one group of fixed pulley 4 and counterweight wheel 6, and wherein car pulley 3 is fixed together with car 2, and fixed pulley 4 is fixed on well headroom 12, and counterweight wheel 6 is fixed together with counterweight 7; Tensioning member comprises transmission tensioning member 1 and drives tensioning member 8, wherein, described transmission tensioning member 1 one ends are fixed on well headroom 12, the other end is walked around car pulley 3, fixed pulley 4 and counterweight wheel 6 at least, and be fixed on well headroom 12, described driving tensioning member 8 one ends are fixed on the car 2, and the other end is walked around the traction sheave of main frame 9 at least, and is fixed on the counterweight 7.
The assembling of car pulley can have dual mode, one, and car pulley 3 has two groups at least, is separately fixed at the right and left of the bottom of car 2.
Its two, car pulley 3 has one group at least, is fixed on the top of car 2, described transmission tensioning member 1 is walked around car pulley 3 and then is walked around fixed pulley 4.
Described tensioning member is steel rope, or the belt conveyor of flats.
Described fixed pulley 4 has two groups at least, bears the weight of car 2 and the weight of counterweight 7 respectively.
The utility model is divided into tensioning member the transmission tensioning member and drives tensioning member, the corresponding requirement that has reduced as steel rope or the belt conveyor of tensioning member, improved the life-span of steel rope or belt conveyor, improve the stressing conditions of host output shaft, because car and the full hoistway height of counterweight all have steel rope or belt conveyor, can replace the effect of compensated chain.Because car and counterweight hang and be driven apart, and have reduced the requirement of steel rope or steel band, have reduced the axle load of main frame, because main frame is contained in well pit, in arranging, no machine room also reduced headroom height.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the structural representation of the utility model embodiment 2.
Among the figure: 1, transmission tensioning member; 2, car; 3, car pulley; 4, fixed pulley; 6, counterweight wheel; 7, counterweight; 8, drive tensioning member; 9, main frame; 11, hoistway bottom; 12, well headroom.
The specific embodiment
The purpose of this utility model, technical scheme and useful technique effect are more clear to be understood in order to make, and below in conjunction with accompanying drawing technology contents of the present utility model and the specific embodiment is described in further detail.Should be understood that the specific embodiment of describing in this specification sheets only is in order to explain the utility model, is not in order to limit the utility model.
