Description

Technical Field

[0001] This utility model belongs to the field of elevator technology, specifically relating to an elevator emergency braking buffer optimization device. Background Technology

[0002] Elevator emergency braking buffer optimization equipment is a mechanical device dedicated to improving the buffering performance of elevators during emergency braking. It ensures that the elevator will not move when stationary and can release the brake when running, aiming to reduce the harm of accidents and protect the safety of personnel and equipment.

[0003] Existing elevator emergency braking buffer optimization devices use a single buffer component, which is difficult to completely absorb the kinetic energy of the elevator falling. Especially in high-speed falling scenarios, the remaining kinetic energy may cause the elevator car to hit the bottom, exacerbating the risk of equipment damage and personal injury. Therefore, an elevator emergency braking buffer optimization device is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an elevator emergency braking buffer optimization device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an elevator emergency braking buffer optimization device, comprising an elevator car, with limit rails fixedly connected to both sides of the elevator car, guide rails slidably connected to the inner walls of the two limit rails, a buffer pad fixedly connected to the bottom of the elevator car, a combined plate fixedly connected to the bottom of the buffer pad, two protective shells fixedly connected to both sides of the combined plate, brakes fixedly connected to the interior of the four protective shells, brake pads fixedly connected to the braking ends of the four brakes, and limit inclined plates fixedly connected to the bottom of the four protective shells. The inclined plates are rotatably connected to pulleys. Protective plates are fixedly connected to the bottom of the four inclined plates. A main spring is fixedly connected to the bottom of the combined plate. A main damper is fixedly connected to the bottom of the combined plate. A force ring is fixedly connected to one end of the main spring. A force collar is fixedly connected to the surface of the force ring. Four connecting rods are fixedly connected to the surface of the force collar. Two force plates are fixedly connected to the surface of the four connecting rods. Four follower springs are fixedly connected to the top of the two force plates. Four follower dampers are fixedly connected to the top of the two force plates. A speed sensor is fixedly connected to the inside of each of the four protective shells.

[0006] By setting up the above structure, the speed sensor can monitor abnormal elevator car speed in real time and trigger the brake, so that the brake pads rub against the guide rail to achieve braking and deceleration. At the same time, the buffer pad, main spring and main damper at the bottom of the elevator car can absorb the kinetic energy of the elevator car falling by compression. With the help of the secondary spring and secondary damper, the remaining kinetic energy can be further consumed. Under the synergistic effect of the above buffer components, a multi-level buffer structure can be formed to gradually absorb the kinetic energy of the elevator car falling, effectively reducing the risk of elevator car collapse and ensuring the safety of the elevator car and personnel.

[0007] As a preferred embodiment, the main spring is sleeved on the surface of the main damper.

[0008] As a preferred embodiment, the top of the force-bearing ring is fixedly connected to one end of the main damper.

[0009] As a preferred embodiment, the two guide rails slide inside the force-bearing plate.

[0010] As a preferred embodiment, one end of the spring is fixedly connected to the bottom of the protective shell.

[0011] As a preferred embodiment, one end of the damper is fixedly connected to the bottom of the protective shell.

[0012] By setting limit rails and guide rails, the limit rails and guide rails work together to limit the displacement of the elevator car during the entire braking and buffering process, ensuring its smooth buffering. The pulleys in the limit inclined plate can help stabilize the movement trajectory of the elevator car, and the protection plate can protect the braking structure composed of the brake, brake pads and pulleys throughout the process.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention, by incorporating a speed sensor, can monitor abnormal elevator car speed in real time and trigger the brake, causing the brake pads to rub against the guide rails to achieve braking and deceleration. Simultaneously, the buffer pads, main springs, and main dampers at the bottom of the elevator car can absorb the kinetic energy of the elevator car falling through compression. In conjunction with the secondary springs and secondary dampers, the remaining kinetic energy can be further dissipated. Under the synergistic effect of the above buffer components, a multi-level buffer structure can be formed to gradually absorb the kinetic energy of the elevator car falling, effectively reducing the risk of elevator car collapse and ensuring the safety of the elevator car and personnel.

[0015] This utility model, by setting a limiting rail and a guide rail, can limit the displacement of the elevator car and ensure its smooth buffering during the entire braking and buffering process. The pulley in the limiting inclined plate can help stabilize the movement trajectory of the elevator car, and the protective plate can protect the braking structure composed of the brake, brake pad and pulley throughout the process.

The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0022] Please see Figure 1-3This utility model provides an elevator emergency braking buffer optimization device, including an elevator car 1. Limiting rails 2 are fixedly connected to both sides of the elevator car 1. Guide rails 3 are slidably connected to the inner walls of the two limiting rails 2. A buffer pad 4 is fixedly connected to the bottom of the elevator car 1. A combined plate 5 is fixedly connected to the bottom of the buffer pad 4. Two protective shells 6 are fixedly connected to both sides of the combined plate 5. Brakes 7 are fixedly connected inside the four protective shells 6. Brake pads 8 are fixedly connected to the braking ends of the four brakes 7. Limiting inclined plates 9 are fixedly connected to the bottom of the four protective shells 6. Pulleys 1 are rotatably connected inside the four limiting inclined plates 9. 0. Protective plates 11 are fixedly connected to the bottom of the four limiting inclined plates 9 respectively. A main spring 12 is fixedly connected to the bottom of the combined plate 5. A main damper 13 is fixedly connected to the bottom of the combined plate 5. A force-bearing ring 14 is fixedly connected to one end of the main spring 12. A force-bearing collar 15 is fixedly connected to the surface of the force-bearing ring 14. Four connecting rods 16 are fixedly connected to the surface of the force-bearing collar 15. Two force-bearing plates 17 are fixedly connected to the surface of the four connecting rods 16. Four slave springs 18 are fixedly connected to the top of the two force-bearing plates 17. Four slave dampers 19 are fixedly connected to the top of the two force-bearing plates 17. Speed ​​sensors 20 are fixedly connected to the inside of the four protective shells 6 respectively. By setting a speed sensor 20, the speed sensor 20 can monitor the abnormal speed of the elevator car 1 in real time and trigger the brake 7, so that the brake pad 8 rubs against the guide rail 3 to achieve braking and deceleration. At the same time, the buffer pad 4, main spring 12 and main damper 13 at the bottom of the elevator car 1 can absorb the kinetic energy of the elevator car 1 falling by compression. With the help of the secondary spring 18 and the secondary damper 19, the remaining kinetic energy can be further consumed. Under the synergistic effect of the above buffer components, a multi-level buffer structure can be formed to gradually absorb the kinetic energy of the elevator car 1 falling, effectively reduce the risk of the elevator car 1 falling, and ensure the safety of the elevator car 1 and the personnel.

[0023] The main spring 12 is sleeved on the surface of the main damper 13.

[0024] The top of the force ring 14 is fixedly connected to one end of the main damper 13.

[0025] The two guide rails 3 slide inside the force plate 17 respectively.

[0026] One end of the spring 18 is fixedly connected to the bottom of the protective shell 6.

[0027] One end of the damper 19 is fixedly connected to the bottom of the protective shell 6. By setting the limit rail 2 and the guide rail 3, the limit rail 2 and the guide rail 3 can restrict the displacement of the elevator car 1 during the entire braking and buffering process, ensuring its smooth buffering. The pulley 10 in the limit inclined plate 9 can help stabilize the movement trajectory of the elevator car 1. The protective plate 11 can protect the braking structure composed of the brake 7, brake pad 8 and pulley 10 throughout the process.

[0028] Working principle and usage process of this utility model:

[0029] When the elevator car 1 falls, the speed sensor 20 monitors the running speed of the elevator car 1 in real time. If an overspeed abnormality is detected, the brake 7 in the protective shell 6 will be triggered immediately, so that the brake pad 8 and the guide rail 3 will rub against each other to brake and decelerate the elevator car 1.

[0030] If the braking distance of the brake pad 8 is too large, the elevator car 1 may still come into contact with the ground. At this time, the buffer pad 4 and the combined plate 5 at the bottom of the elevator car 1 will work together with the main spring 12 and the main damper 13 to absorb kinetic energy through compression. The secondary spring 18 and the secondary damper 19 at the top of the force plate 17 will further consume the remaining kinetic energy through elastic deformation and damping effect. The multiple buffer components work together to gradually absorb the falling kinetic energy, effectively reduce the risk of the elevator car 1 falling, and ensure the safety of the elevator car 1 and the personnel.
