[0027] See also Figure 1-7 , the utility model provides a technical solution:
[0028] A multi-stage anti-fall elevator linear guide structure includes a guide rail body 1 and a connecting plate 2. One side of the connecting plate 2 is fixedly connected to a side 3. An air duct 4 is opened on the inner side of the side 3. A frame shell component 5 is fixedly connected to the inner side of the side 3. A movable locking component 6 is rotatably connected to the inner side of the frame shell component 5 through a bearing. The outer side of the movable locking component 6 is tightly attached to one side of the guide rail body 1. The frame shell component 5 includes a metal shell 51. An active air duct 52 is opened on the inner side of the metal shell 51. One side of the active air duct 52 opened on the metal shell 51 is fixedly connected to a multi-stage electric telescopic rod 53. A sealing plug 54 is fixedly connected to the inner side of the metal shell 51. A rectangular slide 55 is provided on the side, a cylindrical groove 56 is provided on the inner side of the metal shell 51, an axial hole 57 is provided on the inner side of the metal shell 51, and an air hole 58 is provided on the inner side of the metal shell 51. The movable locking assembly 6 includes a sticking wheel 61, an inner shaft rod 62 is fixedly connected to the inner side of the sticking wheel 61, and a slope column 63 is fixedly connected to the outer side of the inner shaft rod 62. A rectangular guide block 66 is slidably connected to the inner side of the rectangular slide 55 opened in the metal shell 51, and a column guide rod 64 is fixedly connected to the bottom end of the rectangular guide block 66. A sealing ring 65 is fixedly connected to the outer side of the column guide rod 64, and an ear seat 67 is fixedly connected to one side of the column guide rod 64, and a roller 68 is rotatably connected to the inner side of the ear seat 67.
[0029] As a further implementation of this solution, the front end of the guide rail body 1 is fitted with the outer side of the wheel 61, the number of the side 3 is two, and the side 3 is fixed to the left and right ends of the rear part of the connecting plate 2. The air duct 4 opened on the side 3 is connected to the air through hole 58 opened on the metal shell 51, and the air duct 4 runs through the lower end of the side 3. Two frame shell assemblies 5 are fixed inside the side 3. The number of frame shell assemblies 5 is the same as the number of movable locking assemblies 6. This layout increases the stability of the structure and ensures that the relevant components can move synchronously during the operation of the elevator, reducing the additional friction and wear caused by the displacement or instability of the components, thereby improving the smoothness and safety of the elevator operation.
[0030] As a further implementation of this solution, the air hole 58 provided in the metal shell 51 is connected to the movable air passage 52 provided in the metal shell 51. The air hole 58 is located between the sealing plug 54 and the column guide rod 64. A sealing ring is fixedly connected to the outside of the sealing plug 54. The sealing plug 54 is fitted with the inner side of the movable air passage 52 provided in the metal shell 51 through the sealing ring. The movable air passage 52 is cylindrical in shape, which ensures the sealing between the sealing plug 54 and the movable air passage 52 and prevents gas leakage after the sealing plug 54 passes over the air hole 58.
[0031] As a further implementation of this solution, the rectangular slide 55 is formed into a rectangular body, and the rectangular guide block 66 is formed into a rectangular body. The rectangular guide block 66 is slidably connected to the inside of the rectangular slide 55 formed in the metal shell 51, thereby ensuring the accuracy of the moving direction of the column guide rod 64 and the effectiveness of the limiting effect, thereby improving the control accuracy and operation stability of the entire braking system.
[0032] As a further implementation of this solution, the column guide rod 64 is shaped like a cylinder, and the outer side of the column guide rod 64 fits with the inner side of the active air channel 52 opened in the metal shell 51, and the outer side of the sealing ring 65 fits with the inner side of the active air channel 52 opened in the metal shell 51. The outer side of the inner shaft rod 62 is fixedly connected with a bearing, and the bearing of the inner shaft rod 62 is fixed to the inner side of the shaft hole 57 opened in the metal shell 51. The slope column 63 is inside the cylindrical groove 56, and the outer side of the roller 68 fits with the right side of the slope column 63. The right side of the slope column 63 is sloped, and the shape of the inner shaft rod 62 is cylindrical. A straight hole is opened on the inner side of the ear seat 67, which improves the rotation flexibility and durability of the inner shaft rod 62, reduces mechanical wear, extends the service life of components, improves the stability and reliability of the elevator braking system, and provides stable support and rotation axis for the inner shaft rod 62. Such structural design improves the stability and braking effect of the entire braking system, ensuring that the elevator can stop safely and quickly in an emergency.
[0033] Working process: First, when the device is operating normally, the connecting plate 2 is fixed to the elevator box body. When the elevator is lifted or lowered, the connecting plate 2 and the edge 3 are driven to move normally. The edge 3 drives the frame shell assembly 5 and the movable locking assembly 6 to move normally. The outer side of the wheel 61 is tightly attached to the guide rail body 1. When the device is lifted or lowered, the wheel 61 rotates. The rotation of the wheel 61 drives the slope column 63 to rotate through the inner shaft 62. The slope column 63 rotates to squeeze the roller 68 that is attached to the right side. The roller 68 rotates on the inner side of the ear seat 67. The inner shaft 62 rotates and is connected to the inner side of the metal shell 51 to prevent the guide rail from sliding. When the body 1 is subjected to long-term friction and deformation, the existing elevator control unit identifies the state of the elevator. When the elevator falls rapidly, the controller controls the multi-stage electric telescopic rod 53 to extend, and the multi-stage electric telescopic rod 53 drives the sealing plug 54 to move toward the column guide rod 64. A sealing ring is provided on the outside of the sealing plug 54 to seal between the sealing plug 54 and the metal shell 51. An air hole is opened inside the metal shell 51 near the multi-stage electric telescopic rod 53 to facilitate constant pressure on the space to the right of the sealing plug 54. When the sealing plug 54 passes over the air hole 58, the sealing plug 5 4 gradually approaches the column guide rod 64, and the active air channel 52 between the sealing plug 54 and the column guide rod 64 is in a sealed state. Under the pressure of the sealing plug 54, the gas inside the active air channel 52 is squeezed. At this time, the column guide rod 64 will encounter huge resistance when moving. The sealing ring 65 plays a role in sealing between the column guide rod 64 and the roller 61. Under the action of the resistance, the column guide rod 64 gradually moves toward the roller 61. The rectangular guide block 66 is slidably connected to the inside of the rectangular slide 55 opened in the metal shell 51, which plays a role in limiting the moving direction of the column guide rod 64. The column guide rod 64 moves, driving the ear seat 67 and the roller 68 to move. The roller 68 rolls on the right side of the slope column 63. Under the squeezing action of the column guide rod 64, the roller 68 continues to apply pressure to the slope column 63. At this time, the slope column 63 gradually stops rotating. After the slope column 63 stops, the roller 61 cannot rotate due to the connection with the inner shaft rod 62. The device uses the damping to convert into pressure to gradually stop the roller 61 from rotating, thereby greatly reducing the friction between the roller 61 and the guide rail body 1, ensuring the integrity of the guide rail body 1, and ensuring the operating efficiency and safety of the entire elevator system.
[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
