Description
Technical Field
[0001] The utility model relates to the technical field of damping buffers, in particular to a damping buffer with adjustable height for elevators. Background Technique
[0002] A damping buffer is a device used to reduce or eliminate vibrations and impacts in a mechanical system. It reduces the vibration amplitude and impact force of the system by absorbing and dispersing energy, thereby improving the stability and safety of the system.
[0003] Currently, damping buffers are installed in elevators. The damping buffers for elevators are crucial components in the elevator safety system. Their main function is to quickly and effectively reduce the impact speed of the elevator or the elevator car and stop it safely during the operation of the elevator when abnormal situations such as overspeed and falling occur, thereby protecting passengers and elevator equipment from being damaged or injured.
[0004] However, the height of the existing damping buffers for elevators cannot be changed, so they cannot be adapted to different types of elevators. They need to be manufactured specifically according to the elevator type, and the scope of application is small.
[0005] Therefore, in view of the above problems, it is necessary for the applicant to design a damping buffer with adjustable height for elevators to solve the problems. Summary of the Invention
[0006] The purpose of the utility model is to provide a damping buffer with adjustable height for elevators to solve the problems mentioned in the above background technique.
[0007] To achieve the above purpose, the utility model provides the following technical solution: A damping buffer with adjustable height for elevators, including a connecting plate, and a buffer spring is fixedly arranged on one side of the connecting plate. One end of the buffer spring away from the connecting plate is fixedly provided with a threaded disc. A threaded sleeve is internally threaded in the threaded disc, and one end of the threaded sleeve is fixedly provided with a connecting piece fixedly installed with the elevator.
[0008] It further includes: an adjusting mechanism for adjusting the length, and the adjusting mechanism is fixedly connected with the connecting plate. The adjusting mechanism includes a fixed sleeve fixedly connected with the connecting plate, and a hollow sleeve is fixedly arranged on the inner surface of one side of the fixed sleeve. A threaded rod is internally threaded in the hollow sleeve, and a hydraulic outer cylinder slidably connected with the fixed sleeve is slidably arranged on the outer surface of the threaded rod.
[0009] Furthermore, a sliding rod is slidably arranged inside the threaded sleeve, and one end of the sliding rod away from the threaded sleeve is fixedly connected with the connecting plate.
[0010] With the above structural design, during use, rotating the threaded sleeve facilitates adjusting the distance between the threaded sleeve and the sliding rod, which will facilitate adjusting the length of the overall damping buffer, so as to adapt to elevators of different specifications and have a wide range of applications.
[0011] Furthermore, a hydraulic inner cylinder is fixedly arranged inside the hydraulic outer cylinder, a piston is slidably arranged on the inner surface of the hydraulic inner cylinder, and one side of the piston is fixedly connected to the end of the threaded rod far from the hollow sleeve.
[0012] With the above structural design, the movement of the threaded rod facilitates driving the movement of the piston. The reciprocating movement of the piston in the hydraulic inner cylinder will consume the impact energy of the elevator, thereby achieving the purpose of buffering and improving the stability and safety of the elevator.
[0013] Furthermore, the piston divides the hydraulic inner cylinder into a first cavity and a second cavity, and oil inlet pipes extending to the outside of the hydraulic outer cylinder are fixedly communicated with one side of the first cavity and the second cavity respectively.
[0014] With the above structural design, it is convenient to fill the first cavity and the second cavity with oil through the oil inlet pipes.
[0015] Furthermore, a return spring is fixedly arranged on the side of the piston far from the threaded rod, and the return spring is fixedly connected to the inner surface of the hydraulic inner cylinder.
[0016] With the above structural design, the return spring and the oil in the hydraulic inner cylinder are convenient for controlling the reciprocating movement of the piston, thereby consuming the impact energy of the elevator.
[0017] Furthermore, a check valve is detachably installed inside the piston, and the two ports of the check valve are respectively fixedly communicated with the first cavity or the second cavity.
[0018] With the above structural design, the check valve can ensure the one-way flow of the oil in the hydraulic inner cylinder, prevent the oil from flowing back, and is convenient for protecting the safety of the system and equipment.
[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows: The damping buffer with adjustable height for elevators has strong buffering ability and can adjust the length, so as to be convenient for adapting to elevators of multiple specifications and has a wide range of applications. The specific content is as follows:

[0021] 2. A buffer spring is provided. When in use, when the impact force of the elevator acts on the connecting piece, the pressure will push the threaded sleeve to slide directionally along the sliding rod. The movement of the threaded sleeve will squeeze the threaded disc, and the threaded disc will push the buffer spring. The buffer spring will consume the impact energy of the elevator, thereby achieving the purpose of buffering and improving the stability and safety of the elevator.

[0030] Through the above structural design, during use, when the impact force of the elevator acts on the connecting member 14, the pressure will push the threaded sleeve 12 to slide directionally along the direction of the sliding rod 13. The movement of the threaded sleeve 12 will squeeze the threaded disc 11, and the threaded disc 11 will push the buffer spring 10, and the buffer spring 10 will consume the impact energy of the elevator, thereby achieving the purpose of buffering and improving the stability and safety of the elevator.
[0031] It further includes an adjusting mechanism 2 for adjusting the length, and the adjusting mechanism 2 is fixedly connected to the connecting plate 1. The adjusting mechanism 2 includes a fixed sleeve 20 fixedly connected to the connecting plate 1. One side inner surface of the fixed sleeve 20 is fixedly provided with a hollow sleeve 21. A threaded rod 22 is threadedly arranged inside the hollow sleeve 21. The outer surface of the threaded rod 22 is slidably provided with a hydraulic outer cylinder 23 slidably connected to the fixed sleeve 20.
[0032] Through the above structural design, during use, when it is necessary to adjust the length of the damping buffer, rotate the hollow sleeve 21. The rotation of the hollow sleeve 21 in cooperation with the threaded rod 22 will change the length of the adjusting mechanism 2, which will facilitate controlling the length of the overall damping buffer, making it adaptable to various elevators, with convenient use and a wide range of applications.
[0033] A hydraulic inner cylinder 25 is fixedly arranged inside the hydraulic outer cylinder 23. A piston 24 is slidably arranged on the inner surface of the hydraulic inner cylinder 25. One side of the piston 24 is fixedly connected to one end of the threaded rod 22 away from the hollow sleeve 21. The piston 24 divides the hydraulic inner cylinder 25 into a first cavity 240 and a second cavity 241.

Working principle: When using the height-adjustable damping buffer for the elevator, when it is necessary to adjust the length of the damping buffer, rotate the hollow sleeve 21. The rotation of the hollow sleeve 21 in cooperation with the threaded rod 22 will change the length of the adjusting mechanism 2, facilitating the control of the overall length of the damping buffer. During use, when the impact force of the elevator acts on the connecting member 14, the pressure will push the threaded sleeve 12 to slide directionally along the slide rod 13. The movement of the threaded sleeve 12 will squeeze the threaded disc 11, and the threaded disc 11 will push the buffer spring 10. The buffer spring 10 will consume the impact energy of the elevator, thereby achieving the purpose of buffering. At the same time, when the threaded sleeve 12 moves to press against the fixed sleeve 20, the fixed sleeve 20 will push the threaded rod 22 to move. The movement of the threaded rod 22 will drive the piston 24 to move. Under the action of the hydraulic fluid in the hydraulic inner cylinder 25 and the return spring 26, the piston 24 will reciprocate within the hydraulic inner cylinder 25, consuming the impact energy of the elevator, thereby achieving the purpose of buffering and improving the stability and safety of the elevator.
