Description

Technical Field

[0001] The present invention relates to the technical field of elevators, and specifically to a passenger elevator with increased capacity, speed, and high transportation capacity. Background Art

[0002] An elevator generally consists of a hoistway, a machine room, a transmission part, a lifting part, a safety device, a control part, etc. Among them, the transmission part is the function of the traction system. The traction system mainly consists of a motor and a steel cable, which are used to output and transmit power to drive the elevator to run.

[0003] Currently, for existing elevators during descent, the kinetic energy of descent cannot be recycled. And if a sudden power outage occurs, a sealed space is formed inside the car. If there are passengers inside the car at this time, the sealed space will cause passengers to suffocate, and it does not have a safety protection function. Secondly, when existing elevators are running, they cannot reasonably distribute the traction force of the traction machine according to the number of passengers inside the car. When it is fully loaded, it cannot ensure that the elevator still runs at high speed. Therefore, the present invention makes further improvements to existing elevators. Summary of the Invention

[0004] (1) Technical Problems to be Solved

[0005] In view of the deficiencies of the prior art, the present invention provides a passenger elevator with increased capacity, speed, and high transportation capacity, which solves the shortcomings that existing elevators cannot ventilate in case of sudden power outage and cannot recycle the kinetic energy of elevator descent.

[0006] (2) Technical Solutions

[0007] To achieve the above objectives, the present invention is realized through the following technical solutions: A passenger elevator with increased capacity, speed, and high transportation capacity includes a shaft and a machine room, and the machine room is located at the top of the shaft. A car is provided inside the shaft, and a traction mechanism for driving the car to lift and lower is provided inside the machine room. A speed limiter is fixed inside the machine room and near the traction mechanism. A counterweight matching the car is provided inside the shaft. A kinetic energy recovery mechanism and a storage battery for recovering the kinetic energy of the car's descent are provided on the upper surface of the car. An air vent is opened on one side of the top wall of the car. An electric telescopic rod is fixed on the upper surface of the car near the air vent. The bottom telescopic end of the electric telescopic rod passes through the top wall of the car and is fixedly connected with a cover plate, and the cover plate fits with the air vent. An emergency light is fixed on the inner top wall of the car, and a main control cabinet is fixed inside the machine room.

[0008] Preferably, a door opening and closing system for driving the car door to open and close is fixed on the top of the car. A plurality of vertical guide rails are fixed inside the shaft, and a guiding mechanism matching the guide rails is fixed on the outer side wall of the car. Through the cooperation of the guide rails and the guiding mechanism, the car can move up and down stably inside the shaft.

[0009] Preferably, a plurality of shock absorption mechanisms are fixed to the inner bottom wall of the shaft. The shock absorption mechanisms can buffer the car when it descends to the bottommost position.

[0010] Preferably, the traction mechanism includes a bottom plate fixed inside the machine room. A first support seat is fixed on the upper surface of the bottom plate. The top end of the first support seat is rotatably connected to a first rotating shaft. A traction wheel is fixed in the middle of the first rotating shaft. A steel wire rope is wound around the surface of the traction wheel. One end of the steel wire rope is fixedly connected to the top wall of the car. The other end of the steel wire rope passes through the speed limiter and is fixedly connected to the counterweight. A worm gear is fixed to one end of the first rotating shaft. A first traction machine is fixed on the upper surface of the bottom plate near the worm gear. A worm is fixed to the driving end of the first traction machine. The worm meshes with the worm gear. When the elevator is running normally and the weight of the passengers inside the car does not exceed the preset value, the first traction machine drives the traction wheel to rotate, thereby driving the car to lift and lower.

[0011] Preferably, a second traction machine is fixed on the upper surface of the bottom plate on the side away from the first traction machine. The driving end of the second traction machine is fixedly connected to the first rotating shaft. When the weight of the passengers inside the car exceeds the preset value, the second traction machine is powered on and also participates in driving the traction wheel to rotate, so that the car can still lift and lower at high speed.

[0012] Preferably, the kinetic energy recovery mechanism includes a second support seat fixed on the upper surface of the car and a driving seat mechanism. A movable generator is provided at the top end of the driving seat mechanism. A second friction disk is fixedly connected to the driving shaft of the generator. The top end of the second support seat is rotatably connected to a second rotating shaft. A wheel disk is fixedly connected to the middle of the second rotating shaft. A driving steel wire is wound around the surface of the wheel disk. One end of the driving steel wire away from the wheel disk is fixedly connected to the inner top wall of the shaft. A first friction disk is fixed to one end of the second rotating shaft near the generator. The first friction disk is in contact with the second friction disk. The generator is electrically connected to the storage battery. When the car descends, the driving steel wire is pulled out from the wheel disk. At this time, the wheel disk starts to rotate, thereby driving the generator to rotate and realizing power generation.

[0013] Preferably, a reset motor is fixed on the second support seat on the side away from the generator. The driving end of the reset motor is fixedly connected to the second rotating shaft. When the car ascends, the wheel disk can be driven to rotate by the reset motor to realize the winding of the steel wire rope.

[0014] Preferably, the driving seat mechanism includes a base, and a chute is provided at the top of the base. A slider is slidably connected inside the chute, and the top end of the slider is fixedly connected to the generator. A lead screw is rotatably connected inside the chute. The lead screw passes through the slider and is in threaded rotation connection with the slider. One side of the outer wall of the base is fixedly provided with a servo motor, and one end of the lead screw close to the servo motor is fixedly connected to the driving end of the servo motor. By driving the lead screw to rotate forward or backward by the servo motor, the slider can be driven to move, thereby driving the generator to move. Only when the first friction disk contacts the second friction disk can the wheel disk drive the generator to rotate and generate electricity.

[0015] Working principle: During operation, the first traction machine drives the worm gear to rotate through the worm, thereby driving the first rotating shaft to rotate. The first rotating shaft drives the traction wheel to rotate, thereby driving the steel wire rope to move. The steel wire rope can pull the car up or down. If the weight of the passengers inside the car exceeds the preset value, the second traction machine will also participate in driving the traction wheel to rotate, so that the car can still maintain high-speed lifting and lowering. When the car is in the descending stage, the servo motor drives the slider and the generator to move towards the wheel disk by driving the lead screw to rotate until the first friction disk contacts the second friction disk. Therefore, the driving steel wire on the surface of the wheel disk will be pulled out during the descending process of the car, and the wheel disk will also rotate accordingly. Through the transmission of the first friction disk and the second friction disk, the generator can be driven to rotate and generate electricity, and the generated electric energy can be stored in the storage battery. When the car rises, the servo motor drives the slider and the generator to move in the opposite direction, so that the first friction disk and the second friction disk are separated. During the ascending process of the car, the reset motor drives the wheel disk to wind up the driving steel wire. When a sudden power failure occurs and the elevator stops operating, the storage battery supplies power to the electric telescopic rod and the emergency lamp, and the electric telescopic rod drives the cover plate to descend, so that the air vent is opened to prevent the inside of the car from being completely sealed.

[0016] (III) Beneficial effects

[0017] The present invention provides a high-capacity passenger elevator with increased capacity and speed and its method. It has the following beneficial effects:

[0018] 1. When in use, by setting the car, the traction mechanism, the speed limiter, the counterweight, the guiding mechanism, the shock-absorbing mechanism and the main control cabinet, the traction mechanism, the traction wheel, the steel wire rope, the worm gear, the first traction machine, the worm and the second traction machine. When the weight of the passengers inside the elevator exceeds the preset value, the second traction machine will participate in driving the traction wheel, so as to ensure that the car can quickly move up and down even when fully loaded, and improve the running speed of the elevator.

[0019] 2. When the present invention is in use, by setting up a kinetic energy recovery mechanism, a storage battery, a ventilation opening, an electric telescopic rod and a cover plate, the kinetic energy recovery mechanism can recover the descending kinetic energy of the car when the car descends and convert it into electric energy to be stored in the storage battery. When a sudden power failure occurs, the storage battery can provide electric energy for the electric telescopic rod, and the electric telescopic rod is used to drive the cover plate to descend, so that the ventilation opening is opened, avoiding the sealing of the interior of the car and causing passengers to suffocate, playing a role in safety protection.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Embodiment:

[0027] Such as Figure 1 - Figure 4As shown in the figure, the embodiment of the present invention provides a passenger elevator with increased capacity, speed, and high transportation capacity, including a shaft 1 and a machine room 2, and the machine room 2 is located at the top of the shaft 1. Inside the shaft 1, there is a car 3. Inside the machine room 2, there is a traction mechanism 4 for driving the car 3 to lift and lower. Inside the machine room 2 and near the traction mechanism 4, a speed limiter 5 is fixed. Inside the shaft 1, there is a counterweight 6 matching the car 3. On the upper surface of the car 3, there is a kinetic energy recovery mechanism 7 for recovering the kinetic energy of the car 3 descending and a storage battery 8. On one side of the top wall of the car 3, there is a ventilation opening 9. Near the ventilation opening 9 on the upper surface of the car 3, an electric telescopic rod 10 is fixed. The bottom telescopic end of the electric telescopic rod 10 passes through the top wall of the car 3 and is fixedly connected to a cover plate 11, and the cover plate 11 fits with the ventilation opening 9. On the inner top wall of the car 3, an emergency light 12 is fixed. Inside the machine room 2, a main control cabinet 17 is fixed. The main control cabinet 17 is used to control the operation of the elevator.

[0028] As Figure 1 shown, a switch door system 13 for driving the car door to open and close is fixed on the top of the car 3. Inside the shaft 1, a plurality of vertical guide rails 14 are fixed. On the outer side wall of the car 3, a guiding mechanism 15 matching the guide rails 14 is fixed. On the inner bottom wall of the shaft 1, a plurality of shock absorption mechanisms 16 are fixed. In this embodiment, the switch door system 13, the guiding mechanism 15, and the shock absorption mechanism 16 are all existing elevator technologies, and their specific working principles are the same as those of existing elevators.

[0029] As Figure 1 and Figure 2 shown, the traction mechanism 4 includes a bottom plate 41 fixed inside the machine room 2. On the upper surface of the bottom plate 41, a first support seat 42 is fixed. The top end of the first support seat 42 is rotatably connected to a first rotating shaft 43. In the middle of the first rotating shaft 43, a traction wheel 44 is fixed, and a steel wire rope 45 is wound on the surface of the traction wheel 44. One end of the steel wire rope 45 is fixedly connected to the top wall of the car 3, and the other end of the steel wire rope 45 passes through the speed limiter 5 and is fixedly connected to the counterweight 6. One end of the first rotating shaft 43 is fixed with a worm gear 46. On the upper surface of the bottom plate 41 and near the worm gear 46, a first traction machine 47 is fixed. The driving end of the first traction machine 47 is fixed with a worm 48, and the worm 48 meshes with the worm gear 46. Since the worm 48 and the worm gear 46 have a self-locking function, only the first traction machine 47 can be used to drive the first rotating shaft 43 and the traction wheel 44 to rotate, and the first traction machine 47 has a self-locking function. When the first traction machine 47 drives the traction wheel 44 to rotate, the car 3 can be driven to rise or fall.

[0030] On the upper surface of the bottom plate 41 and far from the first traction machine 47, a second traction machine 49 is fixed. The driving end of the second traction machine 49 is fixedly connected to the first rotating shaft 43. The second traction machine 49 does not have a self-locking function. Therefore, when the second traction machine 49 does not work, the second traction machine 49 will not affect the rotation of the first rotating shaft 43 either. When the weight of the passengers inside the car 3 exceeds the preset value, the second traction machine 49 will participate in driving the first rotating shaft 43 to rotate to ensure the rapid lifting and lowering of the car 3.

[0031] As Figure 1 , Figure 3 and Figure 4 shown, the kinetic energy recovery mechanism 7 includes a second support base 72 fixed to the upper surface of the car 3 and a driving seat mechanism 71. A movable generator 77 is provided at the top of the driving seat mechanism 71, and a second friction disc 78 is fixedly connected to the driving shaft of the generator 77. A second rotating shaft 73 is rotatably connected to the top of the second support base 72. A wheel disc 74 is fixedly connected to the middle of the second rotating shaft 73. A driving steel wire 75 is wound around the surface of the wheel disc 74, and one end of the driving steel wire 75 away from the wheel disc 74 is fixedly connected to the inner top wall of the shaft 1. A first friction disc 76 is fixed to one end of the second rotating shaft 73 close to the generator 77, and the first friction disc 76 is in contact with the second friction disc 78. The generator 77 is electrically connected to the storage battery 8. When the car 3 descends, the driving steel wire 75 on the wheel disc 74 will be pulled out, and the wheel disc 74 will also rotate. Therefore, the wheel disc 74 will drive the second rotating shaft 73 to rotate. Under the transmission of the first friction disc 76 and the second friction disc 78, the generator 77 is driven to rotate and generate electricity, and the generated electric energy is stored in the storage battery 8, which can supply power to the electric telescopic rod 10 and the emergency lamp 12.

[0032] A reset motor 79 is fixed to one side of the second support base 72 away from the generator 77, and the driving end of the reset motor 79 is fixedly connected to the second rotating shaft 73. When the car 3 ascends, the reset motor 79 can drive the wheel disc 74 to reverse, realizing the winding of the driving steel wire 75.

[0033] The driving seat mechanism 71 includes a base 711, and a chute 712 is opened at the top of the base 711. A slider 713 is slidably connected inside the chute 712, and the top of the slider 713 is fixedly connected to the generator 77. A lead screw 714 is rotatably connected inside the chute 712. The lead screw 714 penetrates through the slider 713 and is in threaded rotation connection with the slider 713. A servo motor 715 is fixed to one side of the outer side wall of the base 711, and one end of the lead screw 714 close to the servo motor 715 is fixedly connected to the driving end of the servo motor 715. Therefore, when the servo motor 715 drives the lead screw 714 to rotate, the slider 713 can be driven to move inside the chute 712, and the slider 713 will drive the generator 77 to move, so that the first friction disc 76 and the second friction disc 78 are in contact or separated.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
