[0024] The following are specific embodiments of the present application and in combination with the accompanying drawings, the technical solutions of the present application are further described, but the present application is not limited to these embodiments. In the following description, providing specific details such as specific configurations and components is only to help comprehensively understand the embodiments of the present application. Therefore, those skilled in the art should clearly understand that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. Additionally, descriptions of known functions and structures are omitted for clarity and conciseness.

[0025] It should be noted that, without conflict, the implementation manners and features in the implementation manners of the present application can be combined with each other.

[0026] Refer to Figures 1 - 4 , the elevator guiding and limiting component 100 includes a fixed bracket 10 and one or more adjustable limiting units 20 arranged on the fixed bracket 10. The elevator guiding and limiting component 100 is a guiding and limiting device for the car, and is used to guide and limit the car to move up and down along the guide rail. Specifically, the limiting wheel of the adjustable limiting unit 20 can press against the guide rail of the elevator and guide the car to move up and down. N adjustable limiting units 20 can be provided on the fixed bracket 10, and N can specifically be 1, 2, 3, 4, 5, 6,....

[0027] Specifically, the adjustable limit unit 20 includes a mounting bracket 21, a limit wheel 22, an elastic element 23, and an adjusting element 24; the limit wheel 22 is rotatably mounted on the mounting bracket 21 and is used to abut against the guide rail 50 of the elevator to limit and guide the movement of the elevator car 40; the mounting bracket 21 is arranged on the fixed bracket 10, and the mounting bracket 21 is movable relative to the fixed bracket 10. The elastic element 23 acts on the mounting bracket 21 to press the limit wheel 22 against the guide rail 50 of the elevator, and the adjusting element 24 is used to adjust the deformation amount of the elastic element 23 to adjust the pressing force of the limit wheel 22.

[0028] In the adjustable limit unit 20, the mounting bracket 21 is movably mounted on the fixed bracket 10, and an elastic element 23 applies an elastic force to the mounting bracket 21 to urge the limit wheel 22 thereon to elastically press against the guide rail of the elevator. During the lifting and lowering of the car, the elastic element 23 can urge the limit wheel 22 to maintain a state of pressing against the guide rail. In an adjustable limit unit 20, one or more limit wheels can be provided. In a specific embodiment, the elastic element 23 can be specifically set as a spring.

[0029] Furthermore, the adjusting element 24 is used to adjust the deformation amount of the elastic element 23 to adjust the elastic force applied to the mounting bracket 21, thereby realizing the adjustment of the pressing force of the limit wheel 22. During installation, the installer can pre-adjust the pressing force of the limit wheel through the adjusting element, and during use, the maintenance personnel can further adjust the pressing force of the limit wheel through the adjusting element to ensure the smooth operation of the car. It should be understood that the adjusting element is used to adjust the deformation amount of the elastic element, and the adjusting element can be designed into various structural components according to needs.

[0030] Furthermore, the adjustable limit unit 20 includes a number of first adjustable limit units 20a and / or a number of second adjustable limit units 20b; for the first adjustable limit unit 20a, the mounting bracket 21 is slidably mounted; for the second adjustable limit unit 20b, the mounting bracket 21 is rotatably mounted.

[0031] Specifically, the above adjustable limit unit 20 includes two structural types, specifically the first adjustable limit unit 20a and the second adjustable limit unit 20b. As Figure 2 shown, for the first adjustable limit unit 20a, its mounting bracket 21 is slidably mounted. In this structural form, the mounting bracket can be slidably adjusted within a certain range, and under the action of the elastic element, the limit wheel on the mounting bracket elastically presses against the guide rail of the elevator. As Figure 3 and Figure 4As shown, for the second adjustable limit unit 20b, its mounting bracket 21 is rotatably mounted. In this structural form, the mounting bracket can be rotationally adjusted within a certain range, and under the action of the elastic element, the limit wheel on the mounting bracket elastically presses against the guide rail of the elevator.

[0032] In the first embodiment of the present application, all of the adjustable limit units 20 of the elevator guiding and limiting assembly 100 are the first adjustable limit units 20a, and the mounting brackets are all slidably mounted. In the second embodiment of the present application, all of the adjustable limit units 20 of the elevator guiding and limiting assembly 100 are the second adjustable limit units 20b, and the mounting brackets are all rotatably mounted. In the third embodiment of the present application, some of the adjustable limit units 20 of the elevator guiding and limiting assembly 100 are the first adjustable limit units 20a, and some are the second adjustable limit units 20b.

[0033] Further referring to Figure 1 , the adjustable limit unit 20 simultaneously includes the first adjustable limit unit 20a and the second adjustable limit unit 20b, and the limit wheels 22 of the first adjustable limit unit 20a and the limit wheels 22 of the second adjustable limit unit 20b are arranged in different directions. In the Figure 1 shown structure, the adjustable limit unit 20 includes one first adjustable limit unit 20a and one second adjustable limit unit 20b, and moreover, the arrangement directions of the limit wheels 22 of the first adjustable limit unit 20a and the limit wheels 22 of the second adjustable limit unit 20b are perpendicular to each other.

[0034] Further referring to Figure 1 , the elevator guiding and limiting assembly 100 further includes a fixed limit wheel 30. The fixed limit wheel 30 is mounted on the fixed bracket 10, and the fixed limit wheel 30 is rotatably mounted on the fixed bracket 10 and is used to abut against the guide rail 50 of the elevator to limit and guide the movement of the elevator car. In the Figure 1 shown structure, the adjustable limit unit 20 includes one first adjustable limit unit 20a, one second adjustable limit unit 20b, and one fixed limit wheel 30. Among them, the arrangement directions of the limit wheel of the second adjustable limit unit 20b and the fixed limit wheel 30 are opposite, and are used to press the guide rail in the reverse direction, and the arrangement directions of the limit wheels of the first adjustable limit unit 20a and the second adjustable limit unit 20b are perpendicular to each other.

[0035] Referring to Figure 2In one embodiment of the present application, for the first adjustable limiting unit 20a, the first adjustable limiting unit 20a further includes guide rods 25 arranged on both sides of the limiting wheel 22, and the mounting bracket 21 is provided with guide holes adapted to the guide rods 25; the guide rods 25 are mounted on the fixed bracket 10, and pass through the guide holes on the mounting bracket 21 to guide the mounting bracket 21 to move; the adjustment element 24 is a nut threadedly matched with the guide rod 25; the elastic element 23 is sleeved on the guide rod 25 and is limited between the nut and the mounting bracket 21; based on the threaded match, the nut can adjust the position along the guide rod 25 to change the deformation amount of the elastic element 23. Further, the guide rod 25 is a bolt, which is mounted on the fixed bracket 10 by threaded match.

[0036] based on Figure 2 The first adjustable limit unit 20a shown in the figure has a guide rod 25 arranged on each side of the limit wheel 22 on the fixed bracket 10. The guide rod 25 passes through the guide hole on the mounting bracket 21, and the mounting bracket 21 can slide up and down along the guide rod 25 to achieve sliding installation. The adjustment element 24 is a nut, which is threadedly matched with the guide rod 25 and can be adjusted up and down along the guide rod 25 by rotation. The elastic element 23 is confined between the nut and the mounting bracket 21. When the nut adjusts its position on the guide rod, the distance between the nut and the mounting bracket 21 changes, and the deformation of the elastic element 23 also changes accordingly, and the clamping force of the limit wheel on the guide rail also changes accordingly. Figure 2 As shown, when the limiting wheel is pressed by the guide rail, the mounting bracket retreats by compressing the elastic element backwards. The greater the compression of the elastic element caused by retreat, the greater the pressure provided by the elastic element.

[0037] refer to Figure 3 and Figure 4 In one embodiment of the present application, for the second adjustable limiting unit 20b, the second adjustable limiting unit 20b further includes a force rod 26, the force rod 26 is movably connected to the mounting bracket 21, and the mounting bracket 21 is rotatably mounted on the fixed bracket 10; the fixed bracket 10 is provided with a limited support 11, the force rod 26 passes through the opening on the limited support 11, and the adjustment element 24 is a nut threadedly matched with the force rod 26; the elastic element 23 is sleeved on the force rod 26 and is limited between the nut and the limited support 11; based on the threaded match, the nut can adjust the position along the force rod 26 to change the deformation of the elastic element 23. Further, the force rod 26 and the limiting wheel 22 are distributed on both sides of the rotation connection part of the mounting bracket 21.

[0038] based on Figure 3 and Figure 4 The second adjustable limit unit 20b shown is mounted on the fixed bracket 10, and the mounting bracket 21 is rotatably mounted, and can be rotated and adjusted based on the rotating connection part k. Figure 3As shown, the mounting bracket 21 is a long strip structure, and the force application rod 26 and the limiting wheel 22 are respectively located on both sides of the rotational connection part k. The force application rod 26 is movably connected to the mounting bracket 21. The force application rod 26 is used to apply a force to the mounting bracket 21 to press the limiting wheel on the mounting bracket against the guide rail. Further, the adjusting element 24 is a nut, which is in threaded cooperation with the force application rod 26. A limiting support 11 is provided on the fixing bracket 10. The force application rod 26 passes through the limiting support 11, and the elastic element 23 is restricted between the nut and the limiting support 11. When the nut adjusts its position on the force application rod 26 by rotation, the distance between the nut and the limiting support 11 changes, the deformation amount of the elastic element 23 also changes accordingly, and the pressing force of the limiting wheel on the guide rail also changes accordingly. When the limiting wheel is pressed against the guide rail, the mounting bracket rotates backward, and the rotation of the mounting bracket causes the elastic element to be compressed.

[0039] Reference Figure 5 and Figure 6 , the embodiment of the present application also provides a car, and the car 40 includes the elevator guiding and limiting assembly 100 provided in the previous part. In Figure 5 the structure shown, two elevator guiding and limiting assemblies 100 are arranged on the upper and lower sides at the rear of the car 40 respectively.

Two elevator guiding and limiting assemblies 100 are arranged on the upper and lower sides at the rear of the car 40 respectively. The elevator guiding and limiting assembly 100 can be used to guide the car 40 to run smoothly on the guide rail. For the related technical effects and descriptions, refer to the descriptions in the previous part, and will not be elaborated here.

[0041] In the present application, the elevator guiding and limiting assembly is installed on the car of the elevator, and one or more adjustable limiting units are provided thereon. For the adjustable limiting unit, the mounting bracket can move relative to the fixing bracket, and the elastic element acts on the mounting bracket to press the limiting wheel on it against the guide rail of the elevator. The adjusting element is used to adjust the deformation amount of the elastic element to adjust the pressing force of the limiting wheel. During installation, the limiting wheel can be pre-adjusted through the adjusting element, and during use, the pressing force of the limiting wheel can be further adjusted through the adjusting element to ensure the smooth running of the car.
