Technical Field

[0001] This utility model belongs to the field of elevator safety technology, specifically a highly safe elevator car operation stabilization device. Background Technology

[0002] Elevators have become an indispensable vertical transportation tool for carrying people or goods. Elevator cars have always operated using a wire rope traction drive system. By setting up a machine room, traction motor, and reduction gear on the top floor of the building, the wire rope is driven to pull the car and counterweight along the track in the shaft. Elevators serve a specified number of floors in a building, so their uses are very wide. Therefore, elevator safety protection measures are very important. To ensure the smooth movement of the elevator car, a stabilizing device is installed on the outside of the elevator car. When using the existing stabilizing device, the elevator needs to be stopped suddenly when it reaches the designated floor, which can easily cause the elevator to shake violently, making passengers in the car prone to falling and getting injured. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a highly safe elevator car operation stabilization device, which solves the problem that when the elevator reaches a designated floor, it is necessary to make an emergency stop, which can easily cause the elevator to shake violently, making passengers in the car prone to falling and getting injured due to the shaking.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-safety elevator car operation stabilization device, comprising an elevator body, with linkage seats fixedly connected to both the upper and lower sides of the elevator body, a damping telescopic rod provided on the side of the linkage seat away from the elevator body, and the same protective shell installed on the ends of the two damping telescopic rods away from the linkage seats, with four sliding frames fixedly connected to the bottom and top of the inner side of the protective shell, two limiting grooves symmetrically opened inside each sliding frame, and a movable seat slidably connected inside each sliding frame, with a spring provided on one side of the movable seat, the spring being fixedly connected to the inner wall of the sliding frame, and four connecting rods rotatably connected to the outer wall of the linkage seat via pins, the connecting rods being rotatably connected to the movable seat via pins.

[0005] As a further embodiment of this utility model: limiting sliders are fixedly connected to both sides of the movable seat, and the limiting sliders are slidably connected to the inner wall of the limiting groove.

[0006] As a further embodiment of this utility model: movable rods are fixedly connected to the four corners of the upper and lower sides of the elevator body, and four mounting plates are fixedly connected inside the protective shell. The mounting plates are slidably connected to the movable rods, and a spring is provided on the surface of the movable rod on one side of the mounting plate.

[0007] As a further embodiment of this utility model: both sides of the protective shell are slidably connected to mounting frames, and the side of the mounting frame away from the protective shell is rotatably connected to a pressure rod via a pin, and one end of the pressure rod is rotatably connected to a roller via a pin.

[0008] As a further embodiment of this utility model: a motor is fixedly connected to the bottom of the mounting frame, the motor is provided with a threaded rod through the output shaft, the threaded rod is rotatably connected to the mounting frame through a bearing, a movable block is threadedly connected to the outside of the threaded rod, and the movable block is slidably connected to the inner wall of the mounting frame.

[0009] As a further embodiment of this utility model: a lifting seat is fixedly connected to one side of the movable block, and an adjusting rod is rotatably connected to one side of the lifting seat via a pin, and the adjusting rod is rotatably connected to the pressure rod via a pin.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This highly safe elevator car operation stabilization device, through the setting of elevator body, damping telescopic rod, connecting rod and sliding frame, when the elevator body moves or stops suddenly, the elevator body can drive the damping telescopic rod and connecting rod to move together through the linkage seat. The friction generated by the movement of the damping telescopic rod can buffer the vibration of the elevator body. At the same time, the connecting rod drives the movable seat to slide inside the sliding frame. The sliding friction of the movable seat against the inner wall of the sliding frame generates relative elastic force to reduce the vibration of the elevator body, reduce the vibration caused by the movement or sudden stop of the elevator body, and improve the safety of the elevator body when riding.

[0012] 2. This highly safe elevator car operation stabilization device consists of a motor, a threaded rod, a movable block, and a pressure rod. The motor drives the threaded rod to rotate via its output shaft, causing the threaded rod to slide the movable block inside the mounting frame. The movable block, through a linkage seat, drives an adjusting rod to press against the pressure rod, thereby adjusting the pressure rod. This causes the pressure rod to drive a roller to press against the inner wall of the elevator shaft, improving the stability of the elevator body during movement. Attached Figure Description

[0017] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0018] like Figure 1-3 As shown, this utility model provides a technical solution: a high-safety elevator car operation stabilization device, including an elevator body 1, with movable rods 11 fixedly connected to the four corners on the upper and lower sides of the elevator body 1, and four mounting plates 12 fixedly connected inside the protective shell 4. The mounting plates 12 are slidably connected to the movable rods 11, and a spring 13 is provided on the surface of the movable rod 11 on one side of the mounting plate 12. By setting the movable rod 11, the movable rod 11 can slide within the mounting plate 12 as the elevator body 1 shakes, so that the mounting plate 12 can limit the shaking of the elevator body 1 through the movable rod 11.

[0019] The elevator body 1 is fixedly connected to the upper and lower sides with linkage seats 2. The linkage seats 2 are provided with damping telescopic rods 3 on the side away from the elevator body 1. The two damping telescopic rods 3 are installed with the same protective shell 4 at the ends away from the linkage seats 2. The protective shell 4 is slidably connected to the two sides with mounting frames 14. The mounting frame 14 is rotatably connected to the side away from the protective shell 4 by a pin shaft with a pressure rod 15. One end of the pressure rod 15 is rotatably connected to a roller 16 by a pin shaft. By setting the roller 16, the roller 16 can slide on the inner wall of the elevator shaft as the elevator body 1 moves, so that the roller 16 can cooperate with the pressure rod 15 to make the elevator body 1 move stably inside the elevator shaft.

[0020] A motor 17 is fixedly connected to the bottom of the mounting frame 14. The motor 17 has a threaded rod 18 on its output shaft. The threaded rod 18 is rotatably connected to the mounting frame 14 via a bearing. A movable block 19 is threadedly connected to the outside of the threaded rod 18. The movable block 19 is slidably connected to the inner wall of the mounting frame 14. By setting the threaded rod 18, the threaded rod 18 can rotate together with the output shaft of the motor 17, thereby driving the movable block 19 to slide in the mounting frame 14, so as to adjust the position of the movable block 19 and the adjusting rod 21.

[0021] A lifting seat 20 is fixedly connected to one side of the movable block 19. An adjusting rod 21 is rotatably connected to one side of the lifting seat 20 via a pin. The adjusting rod 21 is rotatably connected to the pressure rod 15 via a pin. By setting the adjusting rod 21, the adjusting rod 21 moves with the lifting seat 20, so that the adjusting rod 21 can drive the pressure rod 15 to rotate, and control the roller 16 to stick to the inner wall of the elevator shaft.

[0022] Four sliding frames 5 are fixedly connected to the bottom and top of the inner shell 4. Two limiting grooves 6 are symmetrically opened inside each sliding frame 5. A movable seat 8 is slidably connected inside each sliding frame 5. Limiting sliders 10 are fixedly connected to both sides of the movable seat 8. The limiting sliders 10 are slidably connected to the inner wall of the limiting groove 6. By setting the limiting sliders 10, the limiting sliders 10 can slide inside the limiting groove 6 as the movable seat 8 moves. Thus, the limiting groove 6 can limit the movement of the movable seat 8 through the limiting sliders 10, so that the movable seat 8 can slide stably inside the sliding frame 5.

[0023] A spring 9 is provided on one side of the movable seat 8. The spring 9 is fixedly connected to the inner wall of the slide frame 5. Four connecting rods 7 are rotatably connected to the outer wall of the linkage seat 2 through pins. The connecting rods 7 are rotatably connected to the movable seat 8 through pins. By setting the spring 9, the movable seat 8 moves and squeezes the spring 9, so that the spring 9 generates a relative elastic force, which facilitates the subsequent reset of the movable seat 8 by the elastic force of the spring 9.

[0024] The working principle of this utility model is as follows:

[0025] The motor 17 is started, and the motor 17 drives the threaded rod 18 to rotate through the output shaft. The threaded rod 18 drives the movable block 19 to move within the mounting frame 14. The movable block 19 drives the adjusting rod 21 to move through the lifting seat 20. The adjusting rod 21 can squeeze the pressure rod 15, thereby causing the pressure rod 15 to rotate and drive the roller 16 to move towards the inner wall of the elevator shaft until the roller 16 abuts against the surface of the inner wall of the elevator shaft, which facilitates the stable movement of the elevator body 1. When the elevator body 1 moves or stops suddenly, the elevator body 1 can simultaneously drive the linkage seat 2 and the movable block 19 on the upper and lower sides of the elevator body 1 to move. The linkage seat 2 simultaneously drives the damping telescopic rod 3 and the connecting rod 7 to slide. The movement of the damping telescopic rod 3 generates friction to dampen the vibration of the elevator body 1. The connecting rod 7 pushes the movable seat 8 to slide inside the slide frame 5. The movable seat 8 squeezes the spring 9 and rubs against the inner wall of the slide frame 5 to generate relative friction to dampen the vibration of the elevator body 1.
