Description

Technical Field

[0001] This utility model relates to the technical field of shock absorption and buffer devices, and in particular to a shock absorption and buffer device for elevator lifting. Background Technology

[0002] Elevators, as an indispensable vertical transportation device in modern buildings, are widely used in various high-rise buildings, commercial centers, hospitals, residences and other places. With the acceleration of urbanization and the continuous increase in building height, people have put forward higher and higher requirements for the safety, comfort and reliability of elevators. The stable operation of elevators is not only related to the life safety of passengers, but also directly affects people's daily travel experience.

[0003] During elevator operation, the supporting structure of existing elevator lifting devices is prone to swaying. With frequent lifting and lowering and prolonged use, this may affect the normal operation of the elevator and even cause safety hazards. Existing elevator shock absorption devices may have simple structures and are difficult to buffer when faced with vibrations and impacts generated during elevator operation. As a result, a large amount of vibration and impact force is directly transmitted to the elevator car, which can damage the electronic equipment and precision components inside the elevator, affecting its normal operation and lifespan. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a shock-absorbing and buffering device for elevator lifting.

[0005] This utility model is achieved by the following technical solution: a shock-absorbing and buffering device for elevator lifting, including a lifting mechanism, a buffering mechanism at the bottom of the lifting mechanism, and a support mechanism at the bottom of the buffering mechanism.

[0006] The lifting mechanism includes a base, a support column is fixedly connected inside the base, a support ring is fixedly connected to the top of the support column, a connecting block is fixedly connected to one side of the support column, a sliding groove is provided on the side of the connecting block away from the support column, a limit shaft is provided in the sliding groove, and the limit shaft is fixedly connected to the connecting block.

[0007] Through the above technical solution, the lifting mechanism and the support column provide stable support for the device. The support ring enhances the stability of the top of the support column. The sliding block can slide smoothly along the limit shaft through the groove and limit shaft of the connecting block, which greatly improves the smoothness of the elevator lifting and reduces shaking and deviation.

[0008] As a further improvement to the above solution, a sliding block is sleeved on the surface of the limiting shaft, a support block is fixedly connected to the side of the sliding block away from the connecting block, a support plate is fixedly connected to the top of the support block, and an elevator is fixedly connected to the top of the support plate.

[0009] As a further improvement to the above solution, the buffer mechanism includes a first buffer disk, a buffer plate fixedly connected to the top of the first buffer disk, a second buffer disk fixedly connected to the top of the buffer plate, a load-bearing block fixedly connected to the top of the second buffer disk, and a load-bearing plate fixedly connected to the top of the load-bearing block.

[0010] As a further improvement to the above solution, the load-bearing plate is fixedly connected to the base, a protective plate is fixedly connected to the top of the load-bearing plate, a protective frame is fixedly connected to the top of the protective plate, a first protective rod is fixedly connected to the top of the protective plate, a second protective rod is sleeved on the top of the first protective rod, and the second protective rod is fixedly connected to the support block.

[0011] Through the above technical solution, the buffer mechanism can effectively absorb and disperse the vibration and impact force generated during elevator operation. When the elevator is subjected to vibration or impact, the first buffer plate first bears part of the force, and then the buffer plate further buffers the remaining impact force, thereby dispersing the impact force to a larger area and ensuring that the vibration and impact force transmitted to the elevator car is greatly reduced, thus improving the safety of the device. Through the load-bearing block and load-bearing plate, it not only plays the role of bearing the weight of the elevator, but also assists the buffer plate in playing a stable role during the buffering process, ensuring the reliability of the entire buffering process.

[0012] As a further improvement to the above solution, the support mechanism includes a base plate, a stabilizing frame is fixedly connected to the top of the base plate, a first fixed shaft is fixedly connected to both sides of the stabilizing frame, a belt is sleeved on the surface of the first fixed shaft, a second fixed shaft is sleeved on the side of the belt away from the first fixed shaft, and the second fixed shaft is fixedly connected to the base plate.

[0013] As a further improvement to the above solution, the stabilizing frame is fixedly connected to the first buffer disk.

[0014] The above technical solution, through the support mechanism, provides a solid foundation for the entire device. The stabilizing frame enhances the stability of the overall structure. When the stabilizing frame is subjected to external force, the belt can rotate around the first and second fixed axes, thus ensuring the stability and flexibility of the connection between the stabilizing frame and the base plate. This allows it to adapt to possible angle changes during elevator operation, thereby improving the reliability and durability of the device.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention utilizes a lifting mechanism, which in turn provides stable support to the device via a support column. The support ring enhances the stability of the support column top. Through the sliding groove and limiting shaft in the connecting block, the sliding block can slide smoothly along the limiting shaft, greatly improving the smoothness of elevator lifting and reducing swaying and deviation. The buffer mechanism effectively absorbs and disperses the vibrations and impacts generated during elevator operation. When the elevator is subjected to vibration or impact, the first buffer plate first absorbs part of the force, and then the buffer plate further buffers the remaining impact force, thus distributing the impact force over a larger area and ensuring that the vibrations and impacts transmitted to the elevator car are effectively contained. The force is significantly reduced, thereby improving the safety of the device. The load-bearing blocks and plates not only bear the weight of the elevator, but also assist the buffer plate in playing a stable role during the buffering process, ensuring the reliability of the entire buffering process. The support mechanism provides a solid foundation for the entire device, and the stabilizing frame enhances the stability of the overall structure. When the stabilizing frame is subjected to external force, the belt can rotate around the first and second fixed axes, thereby ensuring the stability and flexibility of the connection between the stabilizing frame and the base plate. This allows it to adapt to possible angle changes during elevator operation, thereby improving the reliability and durability of the device. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] Example:

[0026] Please combine Figure 1-5 This embodiment provides a shock-absorbing and buffering device for elevator lifting, including a lifting mechanism 1, a buffering mechanism 2 at the bottom of the lifting mechanism 1, and a support mechanism 3 at the bottom of the buffering mechanism 2.

[0027] The lifting mechanism 1 includes a base 101, a support column 102 is fixedly connected inside the base 101, a support ring 103 is fixedly connected to the top of the support column 102, a connecting block is fixedly connected to one side of the support column 102, a sliding groove is provided on the side of the connecting block away from the support column 102, a limit shaft is provided in the sliding groove, and the limit shaft is fixedly connected to the connecting block.

[0028] A sliding block 104 is sleeved on the surface of the limiting shaft. A support block 105 is fixedly connected to the side of the sliding block 104 away from the connecting block. A support plate is fixedly connected to the top of the support block 105. An elevator is fixedly connected to the top of the support plate.

[0029] The buffer mechanism 2 includes a first buffer plate 201, a buffer plate fixedly connected to the top of the first buffer plate 201, a second buffer plate 202 fixedly connected to the top of the buffer plate, a load-bearing block 203 fixedly connected to the top of the second buffer plate 202, and a load-bearing plate 204 fixedly connected to the top of the load-bearing block 203.

[0030] The load-bearing plate 204 is fixedly connected to the base 101. A protective plate is fixedly connected to the top of the load-bearing plate 204. A protective frame 205 is fixedly connected to the top of the protective plate. A first protective rod is fixedly connected to the top of the protective plate. A second protective rod is sleeved on the top of the first protective rod. The second protective rod is fixedly connected to the support block 105.

[0031] The support mechanism 3 includes a base plate 301, a stabilizing frame 302 is fixedly connected to the top of the base plate 301, a first fixing shaft 303 is fixedly connected to both sides of the stabilizing frame 302, a belt 304 is sleeved on the surface of the first fixing shaft 303, a second fixing shaft 305 is sleeved on the side of the belt 304 away from the first fixing shaft 303, and the second fixing shaft 305 is fixedly connected to the base plate 301.

[0032] The stabilizing frame 302 is fixedly connected to the first buffer disk 201.

[0033] The implementation principle of one embodiment of this application is as follows: When the elevator rises or falls, the support block 105 slides in the groove along the limiting shaft. Due to the limiting effect of the limiting shaft, the support block 105 can only move in a straight line, thereby driving the support plate and the elevator to rise or fall smoothly. During the operation of the elevator, when encountering vibration or impact, firstly, the impact force transmitted by the elevator acts on the load-bearing plate 204. The load-bearing plate 204 transmits the force to the load-bearing block 203, and then passes through the second buffer plate 202, the buffer plate and the first buffer plate 201 in sequence, thereby gradually absorbing and dispersing the impact force, thereby greatly reducing the vibration amplitude transmitted to the elevator car. During the operation of the elevator, when the device is subjected to forces from different directions, the belt 304 can rotate around the axis within a certain range to ensure that the stabilizing frame 302 always provides stable support for the buffer mechanism 2 and the lifting mechanism 1, maintaining the balance and stability of the entire device.

[0034] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
