Description

Technical Field

[0001] This application relates to the field of elevator equipment technology, and in particular to a shock-absorbing and anti-tilting device for elevator traction machines. Background Technology

[0002] With the development of elevator technology and the improvement of people's living standards, elevators are increasingly widely used in daily life and have become an indispensable part of daily life. An elevator mainly consists of a traction machine, guide rails, a counterweight, a car, and landing doors. The traction machine is usually installed in a machine room and typically uses wire rope friction drive. The wire rope passes around the traction sheave, with both ends connected to the car and the counterweight, respectively. The motor drives the traction sheave to raise and lower the car.

[0003] Elevator traction machines generate vibrations during operation, which are transmitted through the installation station to the building walls and then to the residential buildings, creating noise that affects residents' sleep and health. Existing vibration damping structures are generally made of rubber, which is ineffective. Moreover, in actual operation, elevator traction machines do not only vibrate in the vertical direction. For example, the elevator's start-up and stop processes cause changes in the direction of the force, and the randomness of the passengers' positions inside the car also causes changes in the direction of the force each time they get on and off the elevator. As a result, the elevator traction machine exerts a non-vertical force on the vibration damper. This force causes the top plate of the vibration damper to shift non-vertically. How to counteract and reduce this force has become one of the urgent problems to be solved by those skilled in the art. If a spring-based vibration damping structure is used, due to the characteristics of the spring itself, when it ages or is damaged and loses its elasticity, it can easily cause the entire elevator to tilt, thus affecting its safety. Summary of the Invention

[0004] This invention provides a shock-absorbing and anti-tilting device for elevator traction machines to solve the above-mentioned technical problems. The specific implementation method is as follows:

[0005] A shock-absorbing and anti-tilting device for an elevator traction machine, comprising:

[0006] Elevator car;

[0007] The mounting base and the limiting rod located vertically on the side of the mounting base are slidably connected. The mounting base is connected to the traction machine to achieve vertical lifting.

[0008] The shock absorption assembly is located between the mounting base and the elevator car. It consists of a first shock absorption structure located in the center and a second shock absorption structure located around the perimeter. The second shock absorption structure is an elastic telescopic component with a rotatable angle. The elastic telescopic component has a built-in proximity switch for detecting whether it has lost its elasticity. When the elevator car tends to tilt during normal operation, the corresponding elastic telescopic component generates a reverse pressure, and the remaining elastic telescopic component generates a tensile force, thereby improving the shock absorption effect during elevator operation.

[0009] The anti-tilt component is a motor-driven telescopic structure. When the elastic telescopic component loses its elasticity or the elevator stalls, the anti-tilt component extends a locking block that is interference-fitted with the limit rod, thereby restoring the elevator car to a stable and locked position.

[0010] The controller's signal input is electrically connected to a proximity switch and a speed sensor mounted on the elevator car. The speed sensor is used to detect whether the elevator's lifting speed is abnormal, and its signal output is electrically connected to the motor.

[0011] Based on the above technical solution, a reflective photoelectric speed sensor is selected as the speed sensor. It is often used to measure the speed of elevator cars during the lifting and lowering process. It does not need to contact the object being measured during use. A reflective surface is fixed on the turntable where the speed to be measured, and the black turntable is used as a non-reflective surface. The two have different reflectivities. When the shaft rotates, the reflective and non-reflective surfaces appear alternately. The photoelectric device indirectly receives the reflected light signal, converts it into an electrical pulse signal, and the speed value can be obtained after processing.

A proximity switch is located between the two horizontal plates to detect the change in the distance between them.

[0014] Optionally, the first shock-absorbing structure specifically comprises a fixed rod and an arc-shaped deformation ring located at the center of the top of the elevator car. A circular through hole is provided at the center of the mounting base, the fixed rod is fitted inside the circular through hole, and the diameter of the circular through hole is larger than the diameter of the fixed rod. Several arc-shaped deformation rings are equidistantly arranged along the circumference between the fixed rod and the circular through hole.

[0015] Optionally, the bottom of the fixing rod is configured as a second conical platform, the lower part of the circular through hole is provided with a hollow first conical platform, and a first spring for vertical buffering is provided between the first conical platform and the second conical platform.

[0016] Optionally, a drive assembly is also provided between the anti-tilt component and the motor, which includes four L-shaped positioning plates located on the top of the elevator car. The four L-shaped positioning plates are arranged in a rectangular shape. A screw is provided between two adjacent L-shaped positioning plates. The ends of the adjacent screws are meshed with helical gears. The output end of the motor is connected to any screw via a belt structure.

[0017] Optionally, several anti-tilt components are provided. Each anti-tilt component includes two sliders threaded to both sides of a screw, with the threads on both sides of the screw in opposite directions. A positioning groove is provided on the top of the elevator car parallel to the screw direction. A limiting block is provided on the slider for sliding into the positioning groove. A connecting rod is rotatably connected to the side of each slider. The other end of the connecting rod is connected to a translation seat. The two connecting rods are in a cross-shaped X structure. A locking block with a rotatable angle is provided on the outside of the translation seat. The locking block and the translation seat are provided with a corresponding arc-shaped reset structure.

[0018] Optionally, the connecting rod is provided with a second limiting groove along its length, and a telescopic support rod is vertically fixed at the center of the intersection between the two second limiting grooves, with the two ends of the telescopic support rod connected to the mounting base and the elevator car respectively.

[0019] Optionally, the translation seat includes a U-shaped block hinged to the connecting rod. The back of the U-shaped block is provided with two reverse extension plates, and a fixed shaft is provided between the two reverse extension plates.

[0042] The following is in conjunction with the appendix Figure 1-12 This application will be described in further detail.

[0043] This application discloses a shock-absorbing and anti-tilting device for elevator traction machines. Example 1

[0044] Reference Figures 1 to 12This embodiment provides a shock-absorbing and anti-tilting device for an elevator traction machine, including an elevator car 5, a mounting base 3, a limiting rod 1, and a shock-absorbing assembly. The limiting rod 1 is vertically disposed on the three-way side of the mounting base 3 (not disposed on the opening / closing door side of the elevator car 5), and the two are slidably connected. The mounting base 3 achieves vertical lifting and lowering by connecting with the traction machine. The shock-absorbing assembly is disposed between the mounting base 3 and the elevator car 5, and consists of a first shock-absorbing structure disposed in the center and a second shock-absorbing structure disposed around the perimeter. In this structure, the mounting base 3 is connected to the output part of the traction machine, and the first and second shock-absorbing structures achieve omnidirectional shock absorption of the elevator car 5 relative to the mounting base 3.

[0045] The second damping structure is a rotatable elastic damping rod 4. The elastic damping rod 4 has spheres 401 on both sides and two interlocking L-shaped plug plates 403 on the inner side. Each L-shaped plug plate 403 is fixedly connected to the sphere 401 at its adjacent position. A second spring 402 is sleeved on the outer side of the two L-shaped plug plates 403. The two spheres 401 are rotatably connected to the top of the elevator car 5 and the bottom of the mounting base 3, respectively. In this structure, the two L-shaped plug plates 403 can be displaced along the direction of the horizontal plate 4034. The vertical plate 4033 of any L-shaped plug plate 403 can be connected to the horizontal plate 4034 of the other L-shaped plug plate 403 through the spring, thereby improving the damping and restoring effect after the elastic damping rod 4 undergoes corresponding deformation.

[0046] The first shock absorption structure specifically consists of a fixed rod 501 and an arc-shaped deformation ring 9 located at the center of the top of the elevator car 5. A circular through hole 301 is provided at the center of the mounting base 3. The fixed rod 501 is fitted into the circular through hole 301, and the diameter of the circular through hole 301 is larger than the diameter of the fixed rod 501. Several arc-shaped deformation rings 9 are equidistantly arranged along the circumference between the fixed rod 501 and the circular through hole 301. In this structure, the fixed rod 501 can tilt at any angle following the elevator car 5. The corresponding arc-shaped deformation ring 9 provides a reverse restoring force, and under the action of all the arc-shaped deformation rings 9, the fixed rod 501 is restored to a vertical state.

[0047] The bottom of the fixing rod 501 is set as a second conical platform 503, and the lower part of the circular through hole 301 is provided with a hollow first conical platform 302. A first spring 11 for vertical buffering is provided between the first conical platform 302 and the second conical platform 503. In this structure, the first spring 11 provides a vertical shock absorption effect. Example 2

[0048] Reference Figures 1 to 12Based on the above embodiments, this embodiment also provides a shock-absorbing and anti-tilting device for an elevator traction machine, which further includes an anti-tilting component 6, a proximity switch 13, a motor 8, and a controller 10. The anti-tilting component 6 is a telescopic structure driven by the motor 8. The signal input terminal of the controller 10 is electrically connected to the proximity switch 13 and the speed sensor 12 installed on the elevator car 5, and its signal output terminal is electrically connected to the motor 8. In this structure, the proximity switch 13 is built into the elastic shock-absorbing rod 4. When the elastic shock-absorbing rod 4 loses its elasticity or the elevator stalls, the anti-tilting component 6 extends a locking block 603 that is interference-fitted with the limit rod 1, thereby restoring the elevator car 5 to a stable and locked state.

[0049] The L-shaped plug-in plate 403 is divided into a vertical plate 4033 pointing towards the center of the sphere 401 and a horizontal plate 4034 perpendicular to the vertical plate 4033. The vertical plate 4033 has a first limiting through groove 4031 along its length. The end of the horizontal plate 4034 has a plug-in block 4032 extending along its length, and the plug-in block 4032 is inserted into the first limiting through groove 4031 on the adjacent side. The proximity switch 13 is located between the two horizontal plates 4034 to detect the change in the distance between them. When the trend of the data change measured by the proximity switch 13 exceeds the normal value, it proves that the elasticity between the two horizontal plates 4034 has been lost.

[0050] A drive assembly 2 is also provided between the anti-tilt component 6 and the motor 8. The drive assembly 2 includes four L-shaped positioning plates 201 located on the top of the elevator car 5. The four L-shaped positioning plates 201 are arranged in a rectangular shape. A screw 202 is provided between two adjacent L-shaped positioning plates 201. The ends of the adjacent screws 202 are meshed with helical gears 203. The output end of the motor 8 is connected to any screw 202 through a belt structure.

[0051] Three anti-tilt components 6 are provided, each corresponding to a limit rod 1. Each anti-tilt component 6 includes two sliders 604 threaded to both sides of a screw 202, with the threads on both sides of the screw 202 in opposite directions. A positioning groove 502 is provided on the top of the elevator car 5 parallel to the direction of the screw 202. A limit block 6041 for sliding into the positioning groove 502 is provided on the slider 604. A connecting rod 601 is rotatably connected to the side of each slider 604. The other end of the connecting rod is connected to a translation seat 602, and the two connecting rods 601 form a cross-shaped X structure. A snap-fit ​​block 603 is provided on the outer side of the translation seat 602.

[0052] The specific implementation process is as follows: When the proximity switch 13 or the speed sensor 12 detects abnormal data, the controller 10 controls the motor 8 to rotate, and then the two sliders 604 move closer together along the screw 202; then the translation seat 602 and the locking block 603 are pushed out horizontally. The locking block 603 is interference-fitted with the limit rod 1, so that friction is generated between the two. Then, during the elevator car 5's stall lifting process, the locking block 603 provides a reverse force to reduce its speed and ensure the safety of passengers in the event of a malfunction. Example 3

[0053] Reference Figures 9 to 11 Based on the above embodiments, this embodiment also provides a shock-absorbing and anti-tilting device for an elevator traction machine. The locking block 603 is rotatable relative to the translation seat 602, and an arc-shaped elastic rod 605 is provided between the two. The translation seat 602 includes a U-shaped block 6021 hinged to the connecting rod 601. The back of the U-shaped block 6021 is provided with two reverse extension plates 6022, and a fixed shaft 6023 is provided between the two reverse extension plates 6022. The locking block 603 is rotatably connected to the fixed shaft 6023. The back of the U-shaped block 6021 is also provided with a fixed seat 6024 parallel to the fixed shaft 6023, and the fixed seat 6024 is connected to the upper and lower parts of the locking block 603 respectively through the arc-shaped elastic rod 605. In this structure, after the locking block 603 is pushed out horizontally, it locks the limiting rod 1. When the elevator car 5 moves vertically, the locking block 603 flips in the opposite direction, thereby improving the interference fit effect between the two.

[0054] The connecting rod 601 has a second limiting through groove 6011 along its length. A telescopic support rod 7 is vertically fixed at the center of the intersection between the two second limiting through grooves 6011. The two ends of the telescopic support rod 7 are respectively connected to the mounting base 3 and the elevator car 5. The connecting rod 601 in this structure is horizontally arranged. During the vertical movement of the elevator car 5, the connecting rod 601 is easily subjected to vertical force. Therefore, the telescopic support rod 7 is added to form a more stable anti-bending structure.

[0055] The side of the limit rod 1 closest to the elevator car 5 is provided with a limit protrusion 101, and the corresponding side of the snap-fit ​​block 603 is also provided with a corresponding limit recess. The vertical cross section of the snap-fit ​​block 603 is designed as an isosceles trapezoidal structure. In this structure, after the snap-fit ​​block 603 flips over, the inclined surface of its isosceles trapezoidal shape rubs against the limit protrusion 101, resulting in a larger contact area between the two and a better stopping effect on the elevator car 5.

[0056] Many other changes and modifications can be made without departing from the concept and scope of this invention. It should be understood that this invention is not limited to the specific embodiments, and the scope of this invention is defined by the appended claims.
