Description

Technical Field

[0001] This invention relates to the field of elevator components technology, specifically to a leveling and anti-slip mechanism for passenger elevators. Background Technology

[0002] With the rapid development of urban construction and the acceleration of urbanization, the number of elevators has increased dramatically year by year. Elevator malfunctions and incidents of people being trapped in slipping elevators are frequent occurrences. Elevator safety is a matter of public concern, and the issue of people being trapped in slipping elevators is a common topic of discussion among ordinary people. Elevator slippage generally has several causes: 1. The brake is not engaging (not engaging) or the brake engagement time is delayed; 2. The brake engages but the braking torque is insufficient, the brake spring is corroded and has lost its elasticity, or the spring force is not properly adjusted, or the spring is too loose; 3. Insufficient traction force, or severe wear of the traction sheave groove; 4. Speed ​​governor malfunction; 5. Safety gear malfunction; 6. Other causes, such as improper adjustment of the landing door or car door, causing the electrical interlocking device of the landing door or car door to intermittently engage or disengage during elevator operation.

[0003] Patent CN214611047U discloses an elevator car leveling anti-slip mechanism, including a car, an elevator shaft, and an anti-slip mechanism. The anti-slip mechanism includes a sliding seat, an anti-slip pin, a limiting seat, a stop groove, and a drive unit. The drive unit includes a rotating shaft, a swing arm, and hinge rods. The ends of the two hinge rods away from the swing arm are hinged to the other ends of the two anti-slip pins. When the rotating shaft rotates, it drives the swing arm to swing, thereby causing the two hinge rods to drive the two anti-slip pins to slide horizontally. The rotating shaft is driven to rotate circumferentially by the rotating unit. The rotation of the rotating shaft causes the swing arm to swing, which in turn drives the two hinge rods to slide the two anti-slip pins horizontally. This allows the anti-slip pins to be inserted into the stop grooves of the two limit seats, thereby limiting the car and preventing it from slipping when the car stops. However, the existing patent CN214611047U uses anti-slip pins that extend outward from inside the elevator car to prevent slipping. This method of extending outward from inside the elevator car is unsafe and does not have a shock absorption effect, resulting in a poor user experience. Therefore, there is an urgent need for a leveling anti-slip mechanism for passenger elevators. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This invention, through the installation of an elevator shaft, an elevator car, a first anti-slip component, a first load-bearing plate, a second anti-slip component, and a second load-bearing plate, achieves the installation of two sets of anti-slip structures below the elevator car, namely the first anti-slip component and the second anti-slip component. The anti-slip plates in the first and second anti-slip components can both rotate and extend below the elevator car, positioning them directly below the elevator car to prevent the elevator car from continuing to descend and slip, thus achieving the purpose of preventing slippage. The anti-slip plates can be retracted when the elevator car is moving normally up or down, without interfering with the normal use of the elevator car. At the same time, the way of extending below the elevator car is relatively safe, and together with the shock-absorbing components installed below, it can improve the passenger's user experience.

[0017] 2. The present invention, through the setting of a first shock-absorbing component and a second shock-absorbing component, realizes the addition of a first shock-absorbing component and a second shock-absorbing component for shock absorption on the anti-slip plate used to prevent the elevator from slipping. The first shock-absorbing component and the second shock-absorbing component are equipped with shock-absorbing rubber, shock-absorbing damping and spring shock-absorbing structure. The three components work together to minimize the vibration experienced by passengers in the elevator car when the elevator stops, thereby achieving the purpose of buffering and shock absorption and making the passenger experience in the elevator car better.

[0018] 3. This invention, through the setting of pressure sensors, timers, and controllers, enables the elevator car to stop on the anti-slip plate. When the pressure sensor receives a weight signal, it will not retract. However, if the timer detects that the stopping time is too long, it may be that there is a problem with the elevator's drive components. In this case, the controller can notify an alarm, increase the alarm path, and improve passenger safety.

[0019] 4. This invention, through the installation of infrared transmitters and receivers, enables the controller to receive signals when the infrared rays are blocked for an extended period. These signals are then sent to the motor, causing it to rotate and extend the anti-slip plate beneath the elevator car to prevent it from slipping. Furthermore, the controller can also activate the motor based on the floor number entered by the passenger. The infrared transmitters and receivers serve as supplementary preventative devices, further preventing situations where the motor fails to activate. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] The embodiments of the present invention will now be described.

[0029] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4A passenger elevator leveling and anti-slip mechanism includes an elevator shaft 1, an elevator car 2 inside the elevator shaft 1, drive components on both sides and the rear of the elevator car 2, and the elevator car 2 moves up and down in the elevator shaft 1 via the drive components. An elevator door is located on the front of the elevator car 2, and an outer door is located on the outside of the elevator shaft 1; both the outer door and the elevator door can be opened. Control buttons are located inside the elevator car 2, which control door opening / closing, floor selection, and alarm activation, and are electrically connected to the elevator master controller. The drive components can be existing pulley systems, which are common elevator drive components. A first anti-slip component 3 is installed at intervals on one side inside the elevator shaft 1. The first anti-slip component 3 includes a motor 301, a reducer 302, an anti-slip plate 303, and a safety device. The system includes a mounting plate 304, pulleys 305, and a sliding groove 306. Motor 301 is located inside elevator shaft 1, and reducer 302 is located at the output end of motor 301. Anti-slip plate 303 is located at the output end of reducer 302, and mounting plate 304 is located below anti-slip plate 303. Pulley 305 is located at the bottom end of one side of anti-slip plate 303, and sliding groove 306 is located inside mounting plate 304. Motor 301 is a forward / reverse motor, and reducer 302 is a worm gear reducer to prevent rotation. The sliding groove 306 on mounting plate 304 does not penetrate through mounting plate 304; the groove trajectory only allows anti-slip plate 303 to slide onto the corresponding first load-bearing plate 4. The matching of pulleys and sliding grooves facilitates motor 301 driving anti-slip plate 303. Reducer 301... The output end of 02 is connected to an output shaft, which is rotatably connected to the mounting plate 304 via a bearing. An anti-slip plate 303 is located outside the output shaft, and is detachably connected to the output shaft via a connector. The anti-slip plate 303 rotates above the mounting plate 304. A pulley 305 and a slide rail 306 are matched. During normal elevator car 2 movement, the anti-slip plate 303 is stored inside the elevator shaft 1 on one side, without obstructing the normal movement of the elevator car 2. The anti-slip plate 303 is made of reinforced and thickened metal steel plate with strong compressive strength. Although only one set of anti-slip plates 303 contacts the elevator car 2 during descent, the anti-slip plates in the first load-bearing plate 4 and the second anti-slip assembly 5 at the bottom share the load. Furthermore, one end of the anti-slip plate 303... A first load-bearing plate 4 is installed on the other side inside the elevator shaft 1. The first load-bearing plate 4 is fixedly installed on one side inside the elevator shaft 1. After the anti-slip plate 303 rotates, its tail end rests on the first load-bearing plate 4. One edge of the first load-bearing plate 4 can seal the protrusion, so that the anti-slip plate 303 can only move within a limited area on the first load-bearing plate 4. Although the first load-bearing plate 4 has a small area, it can be a metal reinforcing plate fixed inside the elevator shaft 1 or a reinforced concrete slab directly embedded into the elevator shaft, and its load-bearing capacity is considerable. Below the anti-slip plate 303, below the motor 301, a second anti-slip component 5 is installed, and a second load-bearing plate 6 is installed below one end of the second anti-slip component 5. The second anti-slip component 5 and the first anti-slip component 3 have the same structure.Furthermore, the second anti-slip component 5 also includes a drive motor, a reducer, an anti-slip plate, a mounting plate, pulleys, and a sliding groove. After the anti-slip plate rotates, its tail end rests on the second load-bearing plate 6. The second anti-slip component 5 has the same structure as the first anti-slip component 3, and the second load-bearing plate 6 has the same structure as the first load-bearing plate 4. The two sets of load-bearing plates are symmetrically arranged but not on the same horizontal plane. Similarly, the two sets of anti-slip components, through the arrangement of elevator shaft 1, elevator car 2, first anti-slip component 3, first load-bearing plate 4, second anti-slip component 5, and second load-bearing plate 6, achieve the installation of two sets of anti-slip components below elevator car 2. The structure used to prevent the elevator car from rolling away consists of a first anti-rollover component 3 and a second anti-rollover component 5. The anti-rollover plates 303 in both components 3 and 5 can rotate and extend from below the elevator car 2, positioning themselves directly beneath it to prevent the elevator car 2 from continuing to descend and roll away. The anti-rollover plates 303 can be retracted during normal elevator car 2 movement, without interfering with its normal operation. The extension mechanism from below the elevator car 2 is also safer, and combined with the shock-absorbing components below, it improves the passenger experience.

[0030] Please see Figure 3 and Figure 5The passenger elevator leveling anti-slip mechanism has a first damping component 7 connected to the top of the anti-slip plate 303. The first damping component 7 includes a first rubber plate 701, a second rubber plate 702, a top plate 703, a bottom plate 704, a buffer damper 705, a longitudinal spring 706, a hinge rod 707, a sleeve block 708, a crossbar 709, and a transverse spring 710. The first rubber plate 701 is located above the anti-slip plate 303, the second rubber plate 702 is located at the top of the anti-slip plate 303, the top plate 703 is located below the first rubber plate 701, the bottom plate 704 is located at the top of the top plate 703, the buffer damper 705 is located between the bottom plate 704 and the top plate 703, and the longitudinal spring 706 is located at one side of the buffer damper 705. On the side, the hinge rod 707 is located on one side of the longitudinal spring 706, the sleeve block 708 is located at one end of the hinge rod 707, and the crossbar 709 is located inside the sleeve block 708. The transverse spring 710 is located on one side of the sleeve block 708 and is sleeved on the outside of the crossbar 709. The top plate 703, bottom plate 704, buffer damping 705, longitudinal spring 706, hinge rod 707, sleeve block 708, crossbar 709, and transverse spring 710 between the first rubber plate 701 and the second rubber plate 702 are all in multiple sets, providing segmented vibration damping and reducing the vibration between the elevator car 2 and the anti-slip plate 303. In addition, when the elevator car 2 descends, the drive assembly will also reduce the speed through the braking assembly to prevent sudden drops. On the anti-slip plate 303, a second shock-absorbing component 8 is provided above the second anti-slip component 5. The first rubber plate 701 and the second rubber plate 702 are both made of rubber, and the first rubber plate 701 is fixedly connected to the top plate 703, the second rubber plate 702 is fixedly connected to the anti-slip plate 303, and the bottom plate 704 is fixedly connected to the second rubber plate 702. Both ends of the hinge rod 707 are provided with pivots, and the hinge rod 707 is rotatably connected to the top plate 703 via the pivots. The hinge rod 707 is rotatably connected to the sleeve block 708 via the pivots, and the sleeve block 708 is sleeved on the outside of the crossbar 709. There are two sets of sleeve blocks 708, and the two sets of sleeve blocks 708 mutually compress and stretch the transverse spring 710 at the middle position. The second shock-absorbing component 8 and... The first shock absorber component 7 has the same structure. The two shock absorber components are laid out in a cross shape on the corresponding anti-slip plate, but they are not on the same horizontal plane. The second shock absorber component 8 below supports the first shock absorber component and provides a certain degree of shock absorption. By setting the first shock absorber component 7 and the second shock absorber component 8, the first shock absorber component 7 and the second shock absorber component 8 for shock absorption are added to the anti-slip plate 303 used to prevent the car from slipping. The first shock absorber component 7 and the second shock absorber component 8 are equipped with shock-absorbing rubber, shock-absorbing damping and spring shock absorption structure. The three work together to minimize the vibration of passengers in the elevator car 2 when the car stops, so as to achieve the purpose of buffering and shock absorption and make the passengers in the elevator car 2 feel better.

[0031] Please see Figure 2 , Figure 5 and Figure 6 The passenger elevator's leveling anti-slip mechanism includes a pressure sensor 9 installed on the anti-slip plate 303, with a timer 10 connected to one side of the pressure sensor 9. A controller 11 is installed on the outside of the elevator shaft 1. The pressure sensor 9 and the timer 10 are electrically connected, as are the timer 10 and the controller 11. The pressure sensor 9, timer 10, and controller 11 work together to enhance passenger safety in the elevator car 2 and reduce the likelihood of the elevator stopping. If the elevator stops, the controller 11 will not control the motor 301 to retract the anti-slip plate. Through the pressure sensor 9, timer 10, and controller 11, the elevator car 2 is positioned on the anti-slip plate 303. The pressure sensor 9 will not retract when it receives a weight signal. However, if the timer 10 detects that the dwell time is too long, it may indicate a problem with the elevator's drive components. In this case, the controller 11 can be used to issue an alarm, increasing the alarm path and improving passenger safety.

[0032] Please see Figure 2 and Figure 6 The passenger elevator's leveling and anti-slip mechanism includes an infrared transmitter 12 installed on one side of the elevator shaft 1, and an infrared receiver 13 installed on the other side of the elevator shaft 1. The infrared transmitter 12 and receiver 13 are electrically connected, and the receiver 13 is also electrically connected to the controller 11. A timer is installed between the infrared transmitter 12 and receiver 13. Under normal circumstances, the infrared light emitted by the infrared transmitter 12 is received by the infrared receiver 13. If there is only a short-term blockage, the controller 11 will not control the motor to start based on the timer's reading. However, if the infrared light is blocked by the elevator car 2 for a prolonged period, the controller will... The controller controls the motor to start based on information about the floors where the elevator car 2 is stopped. Infrared transmitters 12 and 13 act as predictive devices; when the infrared light is blocked for an extended period, the controller 11 receives the signal and sends it to the motor 301. This causes the motor 301 to rotate the anti-slip plate 303, which extends and rotates beneath the elevator car 2 to prevent it from slipping. Furthermore, the controller 11 also controls the motor to start based on the floor number entered by the passenger. The infrared transmitters 12 and 13 serve as supplementary preventative devices, further preventing the motor 301 from failing to start.

[0033] Working principle: During use, the elevator control system controls the elevator car 2 to move up and down. When the control system receives information from a passenger pressing a floor button in elevator car 2, it will control elevator car 2 to move up or down towards the target floor. When elevator car 2 ascends or descends to the target floor, the control system has a braking function, so the time spent entering and staying at the corresponding floor is longer. When elevator car 2 stays between infrared transmitter 12 and infrared receiver 13 for a long time, controller 11 will determine the activation of the first anti-slip component 3 and the second anti-slip component 5 based on the floor command and the information from infrared receiver 13. The first anti-slip component 3... When the motor 301 receives the start command, it drives the anti-slip plate 303 to rotate via the reducer 302. This causes the anti-slip plate 303 to rotate on the mounting plate 304 via pulleys 305 and sliding grooves 306. The anti-slip plate 303 changes from a storage device to an inclined installation in the elevator shaft 1. Simultaneously, one end of the anti-slip plate 303 rests on the first load-bearing plate 4 for easy weight distribution. Similarly, the anti-slip plate in the second anti-slip assembly 5 unfolds, forming a vertically intersecting state with the anti-slip plate 303. When the elevator car 2 descends to the corresponding floor and stays for a period of time, the bottom of the elevator car 2 first contacts the first shock-absorbing assembly 7. The first rubber plate 701 and the second rubber plate 702 in component 7 play a certain role in shock absorption and buffering. The damping 705 in the first shock absorption component 7 can also provide shock absorption and buffering for the elevator car 2. Secondly, the hinge rod 707 rotates due to vibration, thereby pushing the sleeve block 708 to move outside the crossbar 709, pushing the inner transverse spring 710 to compress and expand. Simultaneously, the longitudinal spring 706 located between the top plate 703 and the bottom plate 704 also compresses and expands. The two sets of springs compress and expand in different directions, thus mutually restraining each other and playing a certain counteracting role. Combined with the rubber plate and damping 705, it can... To provide better shock absorption and cushioning, the anti-slip plate 303, while preventing the flow of air, can reduce the vibration felt by passengers in the elevator car 2 by the first shock-absorbing component 7 at the top. When the elevator car 2 stops on the anti-slip plate 303, the pressure sensor 9 will send a signal to the controller 11, and the timer 10 will start timing. If the stop time is too long, the controller 11 will trigger an alarm to prevent the elevator car 2 from accidentally getting stuck on a floor. When the personnel in the control room hear the alarm, they will immediately contact the passengers in the elevator car 2 to inquire whether everything is normal, thus reducing passenger safety hazards.
