Abstract
The invention discloses a traction system for an elevator. The traction system comprises an elevator car, a counterweight device, a motor and a hoisting rope, wherein a counterweight wheel is mounted at the top of the elevator car; an elevator car guide wheel is arranged above the elevator car; one end of the elevator car guide wheel is fixed to the outer surface of the top of the elevator car; the counterweight device comprises a closed piston barrel; a counterweight block is arranged inside the piston barrel; sealing devices are arranged at the upper and lower ends of the counterweight block; a fan is arranged at the lowest end of the piston barrel; a counterweight guide wheel is arranged above the counterweight device; and one end of the hoisting rope is fixed to the surface of the sealing device at the upper end, passes through a traction wheel of the motor through the counterweight guide wheel, and is fixed at the top of the elevator car through the counterweight wheel and the elevator car guide wheel. According to the traction system, the traction system is divided into three sections through the traction wheel of the motor, the elevator car guide wheel and the counterweight wheel to haul the elevator car, a three to one traction effect is achieved, and the stress of the hoisting rope is reduced; and the flow velocity of a gas inside the piston barrel is controlled through the fan, so that the motion of the counterweight block is controlled, the braking of the elevator car is achieved, and the safety is higher.
Description
Technical field
The present invention relates to a kind of elevator traction system, belong to elevator machine technical field of structures.
Background technology
The car of elevator drives mainly by motor and hoist ropes, but owing to the weight of car itself is the biggest, in order to avoid motor is because of by force unbalance, also need to pouring weight to make motor both sides relative equilibrium, ensure that the traction-driven of elevator is normal and the safety of elevator, but pouring weight itself is further increased the burden of hoist ropes, if blindly pursuing and reducing elevator energy consumption and production cost, and ignore the ability to bear of steel wire rope, likely there will be the situation that hoist ropes is broken in the course of the work, bring potential safety hazard to elevator.
Summary of the invention
The technical problem to be solved is the defect overcoming prior art, it is provided that a kind of elevator traction system, alleviates the burden of hoist ropes, improves the security performance of elevator.
For solving above-mentioned technical problem, the present invention provides a kind of elevator traction system, including car, counterweight, motor and hoist ropes；The top of described car is installed roller, and the top of car sets car directive wheel, and one end of car directive wheel is fixed on the outer surface of car roof by hoist ropes, and the other end connects by hoist ropes with to roller；Described counterweight uses piston structure, including the piston cylinder closed, sets pouring weight in piston cylinder, the upper/lower terminal of pouring weight is being set sealing device, will be sealed in pouring weight in piston cylinder, and set counterweight directive wheel above counterweight；One end of hoist ropes is fixed on the surface of end sealing device, through counterweight directive wheel, through the traction sheave of motor, then via to roller, car directive wheel, is fixed on the compartment top of car.
The splicing point of aforesaid car roof and the right-hand member of car directive wheel are positioned on same vertical line, and the left end of described car directive wheel is positioned on same vertical line with to the right-hand member of roller.
The aforesaid wiring point to pouring weight is positioned on same vertical line with the left end of counterweight directive wheel.
Aforesaid sealing device is sealing ring.
The bottom of aforesaid piston cylinder is provided with fan.
The wind-force size of aforesaid fan is adjustable.The beneficial effect that the present invention is reached:
The present invention passes through motor traction sheave, car directive wheel and roller separates three sections draw car, it is achieved the traction effect of three to, alleviates the stress of hoist ropes；It addition, counterweight of the present invention uses piston structure, by the flow velocity of gas in fan control piston cylinder, thus control the motion to pouring weight, it is achieved that the braking of car, safety is higher.
Accompanying drawing explanation
Fig. 1 is the elevator traction system structural representation of the present invention.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.Following example are only used for clearly illustrating technical scheme, and can not limit the scope of the invention with this.
As it is shown in figure 1, the elevator traction system of the present invention includes car 3, counterweight, motor and hoist ropes 10.Wherein, the top of car 3 is installed roller 2, and the top of car 3 sets car directive wheel 1, and one end of car directive wheel 1 is fixed on the outer surface of car 3 compartment top.
Counterweight uses piston structure, including the piston cylinder 6 closed, sets pouring weight 4 in piston cylinder 6, the upper/lower terminal of pouring weight 4 is being set sealing device 7, will be sealed in pouring weight 4 in piston cylinder 6, and set counterweight directive wheel 8 above counterweight.One end of hoist ropes 10 is fixed on the surface of end sealing device 7, through counterweight directive wheel 8, through the traction sheave 9 of motor, then via to roller 2, car directive wheel 1, is fixed on the compartment top of car 3.
Be provided with fan 5 in the bottom of piston cylinder 6, the wind-force size of fan 5 is adjustable, and the flow velocity of gas in controlling piston cylinder 6, so that moving up and down in piston cylinder 6 to pouring weight 4.When elevator stops, closing fan 5, make pouring weight 4 is ignorant of in vertical direction, it is achieved thereby that the braking of car 3.
Concrete, sealing device 7 can be sealing ring.
Concrete, when mounted, the splicing point of car 3 compartment top and the right-hand member of car directive wheel 1 are positioned on same vertical line, the left end of car directive wheel 1 is positioned on same vertical line with to the right-hand member of roller 2, the wiring point of pouring weight 4 and the left end of counterweight directive wheel 8 are positioned on same vertical line, so that hoist ropes is in plumbness as far as possible, improve the pulling effect of hoist ropes.
When real work, the traction sheave rotation traction traction car of motor, and by car directive wheel with roller is separated three sections draw car between motor and car, it is achieved the traction effect of three to, alleviate the stress of hoist ropes.
The above is only the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, on the premise of without departing from the technology of the present invention principle; can also make some improvement and deformation, these improve and deformation also should be regarded as protection scope of the present invention.
