Description

Technical Field

[0001] This utility model belongs to the field of elevator guide shoe technology, and in particular relates to a hydraulically driven rolling guide shoe device based on multi-information fusion. Background Technology

[0002] Guide shoes are installed on the elevator car frame and are in direct contact with the guide rails. Their function is to restrict the elevator car from moving up and down along the guide rails and to suppress or weaken the transmission of vibrations from the guide rails to the car frame and car. Their quality directly determines whether the elevator runs smoothly.

[0003] Common rolling guide shoes typically use damping springs or rubber dampers for shock absorption, which only allows for passive adjustment and cannot actively adjust the contact between the rollers and the guide rails to actively avoid vibration. Furthermore, the vibration of the elevator increases significantly when passengers are going up and down, making real-time adjustment of the rolling guide shoes particularly important. Additionally, when the elevator is stationary, uneven loading can cause permanent deformation of the rollers in the rolling guide shoes, affecting the comfort of the elevator ride. Therefore, it is also necessary to actively adjust the rolling guide shoes to address uneven loading.

[0004] Therefore, adjusting the contact between the rolling guide shoe and the guide rail based on data from the elevator operation process has important practical significance. Utility Model Content

[0005] The purpose of this invention is to provide a hydraulically driven rolling guide shoe device based on multi-information fusion to solve the problems existing in the background art.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A hydraulically driven rolling guide shoe device based on multi-information fusion includes a rolling guide shoe, which is fixed on the elevator car frame and contacts the guide rail. The rolling guide shoe is equipped with a hydraulic adjustment device and a control console.

[0008] The rolling guide shoe includes a base plate and three sets of roller assemblies located on the base plate. The roller assembly includes a roller body, a support arm, and a base. The two ends of the support arm are rotatably connected to the roller body and the base, respectively.

[0009] The hydraulic adjustment device includes a hydraulic cylinder and a hydraulic station. Each roller assembly corresponds to a hydraulic cylinder. One end of the piston rod of the hydraulic cylinder is hinged to the middle of the support arm. The hydraulic cylinder is connected to the hydraulic station through a flow path.

[0010] The control console includes a control system, a vibration sensor, a speed sensor, an angle sensor, and a position encoder. The control system is electrically connected to the hydraulic station.

[0011] Furthermore, a shock-absorbing assembly is provided between the hydraulic cylinder and the support arm. The shock-absorbing assembly includes a telescopic rod and a spring. Fixed plates are provided at both ends of the telescopic rod. The fixed plate at one end of the telescopic rod is fixed to the support arm, and the fixed plate at the other end of the telescopic rod is hinged to the piston rod of the hydraulic cylinder. The spring is sleeved on the outside of the telescopic rod and connected to the two fixed plates.

[0012] Furthermore, the vibration sensor, speed sensor, and angle sensor are respectively fixed to the bottom of the elevator car, and the position encoder is fixed to the outside of the elevator car.

[0013] Furthermore, the control system is integrated with the hydraulic station, and the multiple hydraulic cylinders are adjusted by the control system.

[0014] Furthermore, the control system is wirelessly connected to an external host or mobile device.

[0015] The beneficial effects of this utility model are:

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] See Figures 1-3 This utility model provides a technical solution:

[0024] like Figures 1-3 As shown, a hydraulically driven rolling guide shoe device based on multi-information fusion includes a rolling guide shoe 1, which is fixed on the elevator car frame and in contact with the guide rail. The rolling guide shoe 1 includes a base plate 14 and three sets of roller assemblies located on the base plate 14. The roller assembly includes a roller body 11, a support arm 12 and a base 13. The two ends of the support arm 12 are rotatably connected to the roller body 11 and the base 13, respectively.

[0025] like Figure 1 and Figure 2 As shown, the three sets of roller assemblies are used to contact the three surfaces of the guide rail. Since both ends of the support arm 12 are rotatably connected to the roller body 11 and the base 13 respectively, the rolling friction between the roller body 11 and the guide rail surface is used to adjust and ensure the car moves vertically along the guide rail. The other end of the support arm 12 rotates with the base 13, and the roller body 11 is pressed or loosened against the guide rail surface by adjusting the support arm 12. If the gap is too large, the rolling guide shoe 1 will lose contact with the guide rail, thus affecting the stability of the elevator; if the gap is too small, the friction between the rolling guide shoe 1 and the guide rail will increase, accelerating the wear of the rolling guide shoe 1.

[0026] The rolling guide shoe 1 in this design is equipped with a hydraulic adjustment device 2 and a control console.

[0027] The hydraulic adjustment device 2 includes a hydraulic cylinder 21 and a hydraulic station 22. Each roller assembly corresponds to a hydraulic cylinder 21. One end of the piston rod of the hydraulic cylinder 21 is hinged to the middle of the support arm 12. The hydraulic cylinder 21 is connected to the hydraulic station 22 through a flow path.

[0028] The control console includes a control system, a vibration sensor, a speed sensor, an angle sensor, and a position encoder. The control system is electrically connected to the hydraulic station 22.

[0029] The above technical solution collects elevator operation data through vibration sensors, speed sensors, angle sensors, and position encoders, transmits the data back to the control system, and adjusts the operation of the hydraulic station 22 through the control system. This, in turn, adjusts the output of the corresponding hydraulic cylinders 21. The position of the corresponding support arm 12 is adjusted by pushing or retracting the hydraulic cylinders 21, thereby adjusting the gap between the roller body 11 and the guide rail surface.

[0030] Vibration sensors can detect elevator vibrations and adjust hydraulic cylinders 21 in real time to control the gap between roller body 11 and guide rail surface, reducing impact. An angle sensor can detect whether the elevator car is level. If there is an uneven load, the roller on the lighter side can be adjusted to reduce the gap, increase friction, and maintain stable operation.

[0031] Meanwhile, the speed sensor and position encoder can dynamically adjust the gap between the roller body 11 and the guide rail surface according to the speed of the elevator car. When the elevator stops at each floor, the gap can be reduced and friction increased. The roller body 11 provides a certain friction braking, which facilitates smooth stopping.

[0032] Furthermore, such as Figure 2 and Figure 3 As shown, a shock-absorbing assembly 23 is provided between the hydraulic cylinder 21 and the support arm 12. The shock-absorbing assembly 23 includes a telescopic rod 24 and a spring 25. The telescopic rod 24 has fixing plates 26 at both ends. The fixing plate 26 at one end of the telescopic rod 24 is fixed to the support arm 12, and the fixing plate 26 at the other end of the telescopic rod 24 is hinged to the piston rod of the hydraulic cylinder 21. The spring 25 is sleeved on the telescopic rod 24 and connected to the two fixing plates 26.

[0033] Through the above technical solution, since the telescopic rod 24 has an inner and outer cylinder sleeve structure, when the piston rod of the hydraulic cylinder 21 extends, it will drive the corresponding hinged fixed plate 26 and the outer cylinder of the telescopic rod 24 to move towards the support arm 12. This causes the outer cylinder to move on the inner cylinder, reducing the distance of the telescopic rod 24. The spring 25 then contracts accordingly, and simultaneously, the spring 25 reacts the force of the telescopic rod 24 to the support arm 12, thereby causing the support arm 12 to move. The shock absorption component 23 prevents the hydraulic cylinder 21 from being directly connected to the support arm 12, reducing the impact of vibration during the operation of the rolling guide shoe 1 on the hydraulic cylinder 21.

[0034] Furthermore, the vibration sensor, speed sensor, and angle sensor are respectively fixed to the bottom of the elevator car, and the position encoder is fixed outside the elevator car. The vibration sensor, speed sensor, angle sensor, and position encoder are respectively connected to the control system via wired or wireless means. The control system is wirelessly connected to an external host or mobile device. The control system is integrated with the hydraulic station 22, and the multiple hydraulic cylinders 21 are adjusted through the control system.

[0035] Through the above technical solution, the host of the control system can be directly connected to the hydraulic station 22 and arranged inside the hydraulic station 22. At the same time, the data collected by the control system through various sensors can be transmitted back to external hosts, mobile phones, computers, etc., and the data can be stored in real time for subsequent maintenance and judgment.

[0036] It can also be remotely operated and controlled via an external host or mobile device, and the roller body 11 and guide rail surface can be remotely adjusted for maintenance.

[0037] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
