Description
Technical field
The present invention relates to a kind of traction elevator, particularly a kind of traction propulsive effort is not changed by car weight and steel rope hangs the indirect-drive towed elevator of suspended core distance limit.It is applicable to that passenger elevator, sightseeing elevator, Medical Service Elevator, goods are with vertical lift elevators such as elevators.
Background technology
At present, the traditional traction elevator that in the hoistway of high-rise, is provided with, generally hang car, counterweight, balancing chain (or balance rope) etc. by traction sheave and track adjusting wheel haulage cable and form the suspension driving system by the actuating device towing machine, the friction force that utilizes traction sheave and steel rope to produce provides enough traction propulsive effort direct drive cars to move up and down along hoistway.Traditional towing machine is when design, and its stressing conditions must be considered following two key elements in the lump, promptly considers to provide the bearing capacity of suspension driving systems such as hanging car, counterweight and makes upper and lower the moving of whole suspension driving system that enough moments of torsion are provided.Consider that thus designed towing machine main shaft diameter is bigger, the design of this main shaft also will be considered because of car is decorated the increase of weight, the factors such as increase of lifting travel cause that the weight of steel rope balancing chain or balance rope increases in addition, and have influence on the increasing of towing machine main bearing loading capability, so the diameter of main shaft will correspondingly increase, simultaneously, the volume of towing machine, material consumption all can be bigger.Because towing machine will provide enough driving torques, so steel rope will have enough cornerites on rope sheave, the distance that can make steel rope hang suspended core is subjected to certain limitation.In addition, traditional towing machine direct drive car, the vibration of towing machine inevitably is directly delivered to car, and therefore, the operation noise in the car is bigger, and especially express elevator is even more serious.
Summary of the invention
The purpose of this invention is to provide a kind of indirect-drive towed elevator, it has solved the towing machine main shaft size that direct drive exists in the prior art effectively and influenced by the driving system changes in weight, the serious problem of operation noise, reasonable in design, realize that car drives indirectly, and the traction propulsive effort is not changed by car weight and the restriction of steel rope suspension suspended core distance, can carry out light-weight design and flexible the decoration to car, help machine room, towing machine, to focusing on the random arrangement in the hoistway, reach and simplify the non-standard lift design, enlarge the material field of application, energy-conservation, significantly reduce noise and the purpose that improves the elevator running quality.
The object of the present invention is achieved like this: this elevator comprises towing machine, counterweight, car and connection steel rope therebetween, its technical essential is: described towing machine is assembled on the machine bed girder steel, walk around an end of the driving steel rope of towing machine traction sheave, the following driving movable pulley of driving fixed pulley and counterweight is fixed on the bottom base under the warp, drive the other end of steel rope, the movable pulley that go up to drive through counterweight is connected with tightening device on being fixed on the machine bed girder steel, hanging steel rope on the car is walked around and is fixed on the suspension fixed pulley that hangs the support girder steel, directly is fixed on the counterweight that mates with car.
A described end of walking around the driving steel rope of towing machine traction sheave, go up driving movable pulley through counterweight left and right is connected with tightening device on being fixed on the machine bed girder steel, drive the other end of steel rope, the left and right driving movable pulley down through driving fixed pulley and counterweight is fixed on the bottom base.
A described end of walking around the driving steel rope of towing machine traction sheave, the left and right driving fixed pulley of going up on driving movable pulley and being fixed on the machine bed girder steel of going up through counterweight is connected with tightening device, drive the other end of steel rope, be fixed on the bottom base through the left and right driving movable pulley down of left and right driving fixed pulley down and counterweight.
Hanging steel rope on the described car is walked around and is fixed on the upper and lower suspension fixed pulley that hangs the support girder steel, directly is fixed on the counterweight that mates with car.
Because the two ends of the driving steel rope of towing machine traction sheave are walked around in utilization of the present invention, respectively by on the counterweight, following driving movable pulley is connected on pedestal and the tightening device, form a closed loop traction system, utilize hanging steel rope direct connection car and with the counterweight of its coupling on, so traditional towing machine is provided the dragging and driving mechanism of the integral type direct drive car of suspended load power and moment of torsion, resolve into suspended structure and traction drive configuration two parts of indirect driving, and solved the towing machine main shaft size that direct drive exists in the prior art thus effectively and influenced by the driving system changes in weight, the serious problem of operation noise.The towed elevator reasonable in design that should drive indirectly, can realize the indirect driving of car, not only can fundamentally reduce noise, and the traction propulsive effort is not changed by car weight and the restriction of steel rope suspension suspended core distance, can carry out light-weight design and flexible the decoration to car.So just help to machine room, towing machine, to focusing on the random arrangement in the hoistway, be that machine room is put on can be in hoistway, underlying or side, towing machine can be arranged in the left side or the right side of counterweight, rear side, left side or right side, particularly car that counterweight can be arranged in car can be arranged in different hoistway space with counterweight.From as can be seen above, towing machine main bearing loading capability is low, towing machine is subjected to the influence that car weight changes and lifting travel increases hardly, the calculating of elevator traction propulsive effort is simple relatively, layout in the hoistway becomes quite flexible, therefore not only can reduce the material consumption of towing machine, and also can obtain simplifying the design of non-standard lift.Traditional towed elevator is for guaranteeing pulling ability, and car must enough weigh by design-calculated, has to dispose bigger towing machine.The present invention needn't consider that car weight changes the influence that brings, so the car interior trim has just been had bigger degree of freedom, has enlarged the field of application of materials such as car decoration because the car deadweight is had no effect to towing machine.Influence because of the traction propulsive effort is not changed by car weight so the design of towing machine main shaft diameter can reduce relatively, can reach purpose energy-conservation, material-saving, also can significantly reduce the operation noise simultaneously and improve the elevator running quality.If the present invention disposes current state-of-the-art elevator control technology and permanent-magnet synchronous traction main frame again, so just can provide the better Based Intelligent Control type towed elevator energy-efficient, environmental protection that integrates.
