Description

Technical Field

[0001] This invention belongs to the field of elevator operation control technology, and in particular relates to a low-noise operation control system for elevators at night. Background Technology

[0002] An elevator is a vertical lifting machine powered by an electric motor, equipped with a box-shaped cabin, used for carrying people or goods in multi-story buildings. The rollers in existing elevators generate noise when they come into contact with the elevator guide rails. This noise is not very noticeable during the day when the ambient noise is loud. However, at night, when the ambient noise is low, the noise generated by the rollers coming into contact with the elevator guide rails becomes exceptionally noticeable. For residential buildings, the noise generated can seriously affect the rest of the residents.

[0003] Based on this, CN103818802B discloses a low-noise high-speed elevator, including an elevator car. The elevator car is cylindrical, and both the top and bottom are provided with arc-shaped fairings. The fairings are connected to the elevator car in a rotating manner. A tubular rotating cover is provided outside the elevator car, located between the two fairings, and multiple evenly distributed helical blades are provided outside the rotating cover. Each helical blade extends from the top to the bottom of the rotating cover, and the rotation angle of each helical blade is 25°-50°. This invention can reduce the wind resistance and noise generated during elevator car operation and improve the smoothness of elevator car operation. CN105460750B provides an elevator device and a method for reducing noise inside the elevator car; it provides a simple and inexpensive method for effectively and stably reducing noise inside the elevator car by suppressing acoustic standing waves generated inside the elevator car, as well as a structure for implementing it. When the shape of the ceiling surface, which consists of six surfaces—the floor, ceiling, front, back, and left and right sides—viewed from the inside of the car as approximately quadrilateral, openings are provided at the four vertices of this quadrilateral. A cavity is also provided on the inner side of each opening, as viewed from inside the car. Second-order sound waves are used to control the output of these cavities, thereby radiating control second-order sound waves into the car from the openings at the four vertices of the ceiling surface. The two existing technologies described above address noise reduction during all-weather elevator operation; however, they do not address how to control noise reduction during nighttime operation compared to daytime operation. Summary of the Invention

[0004] The purpose of this invention is to provide a low-noise elevator operation control system for nighttime operation. By switching between daytime and nighttime modes using a first roller group and a second roller group, and by utilizing a nylon layer on the outer side of the second roller in the second roller group, the problem of noise reduction during nighttime elevator operation compared to daytime operation, as proposed in the prior art, is solved.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to a low-noise nighttime operation control system for elevators, comprising a controller connected to a nighttime mode entry module, an elevator car weighing device, a first roller group, and a second roller group. The nighttime mode entry module issues a command to "enter nighttime mode" or "enter daytime mode" upon triggering a preset event. The elevator car weighing device acquires the current load value of the elevator car. The first roller group is mounted on the elevator car and engages with a vertically arranged elevator guide rail. The second roller group is also mounted on the elevator car and engages with a vertically arranged elevator guide rail. The controller receives signals from the nighttime mode entry module and the elevator car weighing device, and controls the first or second roller group to slide along the length of the elevator guide rail.

[0007] Both the first roller assembly and the second roller assembly include a telescopic mounting bracket. The first roller assembly and the second roller assembly also include a first roller and a second roller that are fitted onto the telescopic mounting bracket. The outer side of the first roller is provided with a rubber layer, a metal layer, or a polyurethane layer. The outer side of the second roller is provided with a nylon layer. When entering night mode, the controller controls the second roller assembly to engage with the elevator guide rail. When entering day mode, the controller controls the first roller assembly to engage with the elevator guide rail.

[0008] Furthermore, the elevator nighttime low-noise operation control method based on the aforementioned elevator nighttime low-noise operation control system includes the following steps:

[0009] Step 1: When a preset event is triggered, the night mode entry module sends a command to the controller to enter "night mode", and the controller controls the entry into night mode.

[0010] Step 2: At this point, determine whether the elevator car is stopped at a certain floor. If so, proceed to Step 3; otherwise, continue running until the elevator car is detected and determined to be stopped at a certain floor.

[0011] Step 3: Control the elevator car to descend vertically to the lowest point, and during this process, disable the elevator button trigger signals;

[0012] Step 4: First, control the second roller to extend until it contacts the elevator guide rail, then control the first roller to retract and disengage from the elevator guide rail, and then release the shielding of the elevator buttons.

[0013] Furthermore, in daytime mode, when the elevator car weighing device obtains the current load value of the elevator car, and the controller determines that the load value is greater than the preset value M1, an alarm sound is emitted through the alarm installed in the elevator car; in nighttime mode, when the elevator car weighing device obtains the current load value of the elevator car, and the controller determines that the load value is greater than the preset value M2, an alarm light is emitted through the three-color light installed in the elevator car; wherein M1 > M2.

[0014] Furthermore, the night mode entry module includes a brightness detection module and a sound detection module installed on the top of the building; and both the brightness detection module and the sound detection module are connected to the controller; in daytime mode, when the brightness detection module detects that the ambient brightness is lower than a preset value L1, and the sound detection module detects that the ambient sound is lower than a preset value P1, the night mode entry module determines to enter night mode; then when the brightness detection module detects that the ambient brightness is higher than a preset value L2, and the sound detection module detects that the ambient sound is higher than a preset value P2, the night mode entry module determines to enter daytime mode; where P2 > P1, L2 > L1.

[0015] Furthermore, it also includes an elevator running speed detection module connected to the controller; when in daytime mode, it controls the elevator car to rise and fall at a running speed of V1; when in nighttime mode, it controls the elevator car to rise and fall at a running speed of V2; wherein V1 > V2.

[0016] Furthermore, the telescopic mounting bracket includes a telescopic component and a mounting component that is fitted onto the end of the telescopic component; the mounting component includes a base plate, two columns are provided on one side of the base plate, and a locking plate with a slot on one side is fixedly connected to the top of the two columns; three first rollers or three second rollers are fitted onto the mounting component; and a mounting seat for mounting the first rollers or second rollers is provided on the base plate.

[0017] Furthermore, when three first rollers or three second rollers are installed on the upper part, the axial direction of two of the first rollers is in the X-axis direction, and the axial direction of the other first roller is in the Z-axis direction; the mounting base includes a side plate disposed on the upper surface of the base plate and connected to the column, and a swing arm is rotatably connected to the side plate; one end of the swing arm is equipped with the first roller or the second roller, and the other end of the swing arm is fixedly connected to a buffer arm; the end of the buffer arm away from the swing arm is provided with a through hole A and a through hole B; the column... The column is provided with screws A and B, which are respectively movable through through holes A and B; two bolts A are provided on screw A, which are tightly attached together, and one of the bolts A abuts against the outer wall of the buffer arm; two bolts B are provided on screw B, which are tightly attached together, and a spring A is connected to one side of one of the bolts B, and the end of the spring A is fixed to the outer wall of the buffer arm; the column is also provided with a drive structure that extends and drives the first roller or the second roller to move away from the column; and both through holes A and B are oblong holes.

[0018] Furthermore, the driving structure includes a U-shaped frame fixed on the column, a guide rod movably mounted on the U-shaped frame, and the end of the guide rod being a spherical structure; a telescopic module A is also fixed on the column, the end of which abuts against the end of the guide rod and drives the guide rod to extend and retract along its length; a detection structure is also provided at the bayonet to detect whether the telescopic component controls the installation component to move to a designated position; the detection structure includes an infrared emitting module and an infrared receiving module respectively disposed on both sides of the bayonet, the infrared receiving module receiving infrared light emitted by the infrared emitting module.

[0019] Furthermore, the telescopic component includes a slider connected to the bottom side of the mounting base, the slider being fitted onto a slide rail; one end of the slide rail is fixed to the outer wall of the elevator car; the outer wall of the elevator car is also provided with a telescopic module B that drives the slider to move along the length of the slide rail; the output end of the telescopic module B is connected to the slider via a spring C; the upper surface of the slider has protruding edges on both sides that are connected to the mounting base.

[0020] Furthermore, an electromagnet is provided on the upper surface of the slide rail end, and a magnet that cooperates with the electromagnet is provided on the bottom side of the slider; when the electromagnet is energized, the electromagnet and the magnet repel each other; when the electromagnet is de-energized, the electromagnet and the magnet attract each other.

[0021] The present invention has the following beneficial effects:

[0022] This invention switches between using a first roller group and a second roller group in daytime and nighttime modes. The second roller in the second roller group has a nylon layer on its outer side, while the first roller in the first roller group has a rubber, metal, or polyurethane layer on its outer side. During use, the noise generated by the second roller interacting with the guide rail is lower than that generated by the first roller interacting with the guide rail, thus reducing noise generated during battery operation at night. Simultaneously, during the daytime, when usage is higher, the first roller interacting with the guide rail prevents the second roller with the nylon layer from cracking and deforming due to wear and aging. This overall improves the lifespan of the second roller and the elevator, reducing maintenance frequency.

[0023] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0035] like Figure 1 This invention relates to a low-noise nighttime operation control system for elevators, comprising a controller, a nighttime mode entry module connected to the controller, and a switchable first roller group 1 and second roller group 2. In the nighttime mode, the control switches to engage the second roller group 2 with the vertically arranged elevator guide rail; in the daytime mode, the control switches to engage the first roller group 1 with the vertically arranged elevator guide rail. Both the first roller group 1 and the second roller group 2 include a telescopic mounting bracket, and each also includes a first roller 10 and a second roller mounted on the telescopic mounting bracket. The outer side of the first roller 10 is provided with a polyurethane layer; the outer side of the second roller is provided with a nylon layer. The use of a nylon layer reduces noise generated when the second roller and elevator guide rail are in operation. However, compared to a polyurethane layer, the nylon layer is more prone to cracking and deformation due to wear and aging, resulting in a shorter lifespan. Therefore, this invention, when used in conjunction with the first roller assembly 1, allows for operation during high-frequency daytime use in noisy environments. In such conditions, the noise generated by the first roller assembly 1 and the elevator guide rail is less noticeable. Furthermore, the polyurethane layer, compared to the nylon layer, offers advantages such as a smooth surface, long service life, strong wear resistance, resistance to contamination, and no damage to the elevator steel rope, thus improving the overall lifespan of the elevator.

[0036] In some other possible implementations, the first roller 10 may also be configured as a metal and rubber layer.

[0037] It is understandable that, in one possible implementation, such as Figure 6The telescopic mounting bracket includes a telescopic component 3 and a mounting component 4 that is fitted onto the end of the telescopic component 3. The first roller 10 and the second roller are both fitted onto the mounting component 4. During use, the corresponding first roller 10 and second roller are activated or deactivated by controlling the extension and retraction of the telescopic component 3. When three first rollers 10 or three second rollers are fitted onto the mounting component 4, the axial direction of two first rollers 10 is in the X-axis direction, and the axial direction of the other first roller 10 is in the Z-axis direction.

[0038] Of course, it is known that in this implementation, such as Figure 2-5 The mounting component 4 involved includes a base plate 40, two columns 41 are provided on one side of the base plate 40, and a card plate 42 with a slot 421 on one side is fixedly connected to the top of the two columns 41; a mounting seat 43 for mounting the first roller 10 or the second roller is provided on the base plate 40.

[0039] Specifically, based on the above, the mounting base 43 includes a side plate 430 disposed on the upper surface of the base plate 40 and connected to the column 41. A swing arm 431 is rotatably connected to the side plate 430. A first roller 10 or a second roller is installed on one side of the end of the swing arm 431. The rotatable arrangement of the swing arm 431 facilitates the adjustment of the first roller 10 or the second roller to clamp / abut against the elevator guide rail during use.

[0040] Based on the switching requirements of the first roller group 1 and the second roller group 2, the present invention needs to control the first roller group 1 and the second roller group 2 to cooperate on the elevator guide rail. That is, it is necessary to control the first roller 10 or the second roller to disengage from the elevator guide rail during the control process, so as to facilitate the switching of the first roller group 1 and the second roller group 2.

[0041] Furthermore, in this invention, by setting such as Figure 5 The drive structure 44 drives the first roller 10 or the second roller to move away from the column 41. The drive structure 44 includes a U-shaped frame 440 fixed on the column 41. A guide rod 441 is movably arranged on the U-shaped frame 440. The end of the guide rod 441 is set as a spherical structure 442. A telescopic module A445 is also fixed on the column 41. The end of the guide rod 441 abuts against the end of the guide rod 441 and drives the guide rod 441 to extend and retract along its length. In use, the telescopic module A445 is controlled to drive the guide rod 441 along its length, so that the end of the guide rod 441 abuts against the end of the swing arm 431, thereby driving the swing arm 431 to rotate around the side plate 430. At this time, it is convenient to control the switching process of the first roller group 1 and the second roller group 2.

[0042] Of course, in the above, in order to facilitate the control of the guide rod 441 to return to its initial position, the guide rod 441 and the U-shaped frame 440 are connected to the return spring 444.

[0043] Meanwhile, to facilitate control of the first roller 10 or the second roller being in close contact with the elevator guide rail when the telescopic module A445 is in the retracted state, a buffer arm 432 is fixedly connected to the other side of the end of the swing arm 431; the end of the buffer arm 432 away from the swing arm 431 is provided with a through hole A433 and a through hole B434; the column 41 is provided with a screw A411 and a screw B412 that respectively move through the through hole A433 and the through hole B434; two bolts are provided on the screw A411 that are tightly attached together. A413, and a bolt A413 abuts against the outer wall of the buffer arm 432; two bolts B414 are provided on the screw B412, which are tightly fitted together, and a spring A415 is connected to one side of one bolt B414, the end of the spring A415 is fixed to the outer wall of the buffer arm 432; and the through hole A433 and the through hole B434 are both oblong holes; when the telescopic module A445 extends, the screws A411 and B412 are relatively displaced relative to the through holes A433 and B434 respectively, from Figure 4 Looking upwards, the buffer arm 432 moves upwards and tilts to a certain extent. After the telescopic module A445 retracts, the buffer arm 432 returns to its initial state under the action of the spring A415, at which point the first roller 10 or the second roller is in close contact with the elevator guide rail.

[0044] Of course, based on the above, in order to facilitate the control of the telescopic module A445 to extend or retract at the corresponding time points, such as... Figure 7 The device is equipped with a detection structure at the gate 421 to detect whether the telescopic component 3 controls the installation component 4 to move to the designated position. The detection structure includes an infrared emitting module 4210 and an infrared receiving module 4211 respectively set on both sides of the gate 421. There are two infrared emitting modules 4210 and two infrared receiving modules 4211. Both infrared emitting modules 4210 and infrared receiving modules 4211 are set at both ends of the gate 421. The infrared receiving module 4211 receives the infrared light emitted by the infrared emitting module 4210.

[0045] Based on the above, during the process of the latch 421 latching onto the elevator guide rail, when one infrared receiving module 4211 receives infrared light emitted by the infrared emitting module 4210, it is determined that the latch is being engaged. When another infrared receiving module 4211 also receives infrared light emitted by the infrared emitting module 4210, it is determined that the telescopic module A445 has extended into place. Conversely, during the process of the latch 421 disengaging from the elevator guide rail, when one infrared receiving module 4211 receives infrared light emitted by the infrared emitting module 4210, it is determined that the disengagement is being initiated. When another infrared receiving module 4211 also receives infrared light emitted by the infrared emitting module 4210, it is determined that the telescopic module A445 has retracted into place.

[0046] Based on the above, such as Figure 8To facilitate the smooth movement of the mounting base 43 to the corresponding position, the telescopic component 3 of this invention includes a slider 45 connected to the bottom side of the mounting base 43. The slider 45 is fitted onto a slide rail 46. One end of the slide rail 46 is fixed to the outer wall of the elevator car. A telescopic module B47 is also provided on the outer wall of the elevator car to drive the slider 45 to move along the length of the slide rail 46. The output end of the telescopic module B47 is connected to the slider 45 via a spring C471. The upper surface of the slider 45 has protruding edges 451 on both sides that are connected to the mounting base 43. The movement of the slider 45 is driven by the extension and retraction of the telescopic module B47. At the same time, the spring C471 is connected between the telescopic module B47 and the slider 45. The deformation of the spring C471 prevents the first roller 10 or the second roller from contacting the elevator guide rail, which would cause the slider 45 to vibrate and damage the telescopic module B47.

[0047] An electromagnet 461 is provided on the upper surface of the end of the slide rail 46, and a magnet 452 cooperating with the electromagnet 461 is provided on the bottom side of the slider 45. When the electromagnet 461 is energized, the electromagnet 461 and the magnet 452 repel each other; when the electromagnet 461 is de-energized, the electromagnet 461 and the magnet 452 attract each other. Based on the setting of the electromagnet 461 and the magnet 452, the power is turned off when the slider 45 moves to the corresponding position and is held. At this time, the electromagnet 461 and the magnet 452 fix the slider 45. When it is necessary to control the movement of the slider 45, the electromagnet 461 is energized, and the slider 45 can be disengaged from the slide rail 46.

[0048] It is understood that in this invention, the night mode entry module is used to issue a "enter night mode" or "enter day mode" command when a preset event is triggered; specifically, the night mode entry module includes a brightness detection module and a sound detection module installed on the top of the building; and both the brightness detection module and the sound detection module are connected to the controller; in the day mode state, when the brightness detection module detects that the ambient brightness is lower than the preset value L1, and the sound detection module detects that the ambient sound is lower than the preset value P1, the night mode entry module determines to enter night mode; then when the brightness detection module detects that the ambient brightness is higher than the preset value L2, and the sound detection module detects that the ambient sound is higher than the preset value P2, the night mode entry module determines to enter day mode; P2>P1, L2>L1.

[0049] Meanwhile, the elevator car weighing device is used to obtain the current load value of the elevator car. In daytime mode, when the elevator car weighing device obtains the current load value of the elevator car, and the controller determines that the load value is greater than the preset value M1, an alarm sound is emitted through the alarm installed in the elevator car. In nighttime mode, when the elevator car weighing device obtains the current load value of the elevator car, and the controller determines that the load value is greater than the preset value M2, an alarm light is emitted through the three-color light installed in the elevator car; M1 > M2. Based on the above, the present invention updates the maximum load value of the elevator car at night, and the maximum load value of the elevator car at night is reduced compared to daytime, thereby achieving low-noise operation of the elevator at night.

[0050] The elevator nighttime low-noise operation control method based on the elevator nighttime low-noise operation control system includes the following steps:

[0051] Step 1: When a preset event is triggered, the night mode entry module sends a command to the controller to enter "night mode", and the controller controls the entry into night mode.

[0052] Step 2: At this point, determine whether the elevator car is stopped at a certain floor. If so, proceed to Step 3; otherwise, continue running until the elevator car is detected and determined to be stopped at a certain floor.

[0053] Step 3: Control the elevator car to descend vertically to the lowest point, and during this process, disable the elevator button trigger signals;

[0054] Step 4: First, control the second roller to extend until it contacts the elevator guide rail, then control the first roller 10 to retract and disengage from the elevator guide rail, and then release the shielding of the elevator button.

[0055] The above-mentioned method is set to first detect the status of the elevator car, and when no one is riding, automatically control the elevator car to descend vertically to the lowest point, and complete the switching between the second roller and the first roller 10 at the lowest point. The switching is carried out in the first moment of entering night mode to avoid noise generation. During the switching process, the control of the elevator buttons is automatically disabled to prevent passengers from touching the elevator buttons set on each floor to control the elevator.

[0056] It also includes an elevator speed detection module connected to the controller; when in daytime mode, it controls the elevator car to rise and fall at a speed of V1; when in nighttime mode, it controls the elevator car to rise and fall at a speed of V2; V1 > V2; at night, it achieves low-noise operation of the elevator by reducing the elevator speed.
