Description

Technical Field

[0001] This utility model relates to the technical field of passenger elevator lifting equipment, and in particular to a passenger elevator steel cable guiding device. Background Technology

[0002] A passenger elevator is a permanent transportation device that serves several specific floors within a building. Its car moves on at least two rigid rails that are perpendicular to the horizontal plane or have an inclination angle of less than 15° from the vertical. Passenger elevators run between at least two rigid guide rails that are vertical or have an inclination angle of less than 15°. For example, passenger elevators used in high-rise buildings move vertically by being pulled by passenger elevator cables.

[0003] In the prior art, such as the steel cable limiting and guiding device for passenger elevators in Chinese Patent CN 219906613 U, it includes a mounting plate and a limiting mechanism. The mounting plate has mounting grooves on its upper end, and guide grooves on the front side of the arc surface of each mounting groove. The lower end of the mounting plate has mounting seats, and mounting columns are rotatably connected to the connecting grooves at the lower end of the mounting seats via bearings. Roller frames are provided in the middle of the outer arc surface of each mounting column, and guide wheels are rotatably connected to the clearance grooves at the lower end of the roller frames via pins. This steel cable limiting and guiding device for passenger elevators can limit and guide steel cables of different sizes of passenger elevators through ball bearings during the vertical movement of the passenger elevator body pulled by the steel cables. This replaces the traditional method of limiting and guiding the steel cables of passenger elevators by setting multiple sets of guide wheels. The structure is simple and can ensure that the steel cables of passenger elevators remain stable and perpendicular to the passenger elevator during the operation and lifting of the passenger elevator, preventing arbitrary swinging. However, this patent still has the following problems.

[0004] In the aforementioned patent, although the steel cable of the passenger elevator can be guaranteed to remain perpendicular to the passenger elevator during the elevator's operation and lifting process, preventing arbitrary swaying, the length of the support column and the angle of the support seat set by the patent are fixed. If the installation position is not flat, it may cause the entire device to tilt, thereby affecting the guidance of the steel cable. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that in the existing technology, the length of the support column and the angle of the support seat are fixed, which may cause the whole device to tilt if the installation position is not flat. Therefore, a passenger elevator steel cable guide device is proposed.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a passenger elevator cable guide device, comprising a support platform, with placement frames fixedly installed at the four corners of the bottom of the support platform, an extension plate slidably installed inside the placement frame, a threaded groove opened at the top of the extension plate, a second threaded rod rotatably installed inside the placement frame, the top of the second threaded rod passing through the support platform and fixedly installed with a second handle, the second threaded rod being threadedly connected to the threaded groove, a rotating shaft rotatably installed at the bottom of the extension plate, a rotating block fixedly installed at the bottom of the rotating shaft, rotating rods fixedly installed at both ends of the rotating block, a fixing plate fixedly installed on the opposite sides of the two rotating rods, a connecting plate fixedly installed at the bottom of the two fixing plates, and a bolt threadedly connected to the outer wall of one of the two fixing plates.

[0007] Preferably, the inner wall of the placement frame is provided with a sliding groove, and a slider is fixedly installed on the outer wall of the extension plate, the slider being slidably connected to the sliding groove.

[0008] Preferably, the bottom of the support platform is fixedly installed with three evenly distributed first fixed seats and three evenly distributed second fixed seats. Each of the first fixed seats and the second fixed seats has a rotating plate hinged inside. A guide wheel is rotatably installed at one end of the rotating plate.

[0009] Preferably, three evenly distributed first threaded rods are rotatably mounted on the bottom of the support platform. The top of each first threaded rod passes through the support platform and is fixedly mounted with a first handle. A movable frame is threadedly connected to the outer wall of each first threaded rod.

[0010] Preferably, three evenly distributed limiting rods are fixedly installed at the bottom of the support platform, and the limiting rods pass through the moving frame and are slidably connected to the moving frame.

[0011] Preferably, a limit plate is fixedly installed at the bottom of each of the three limit rods.

[0012] Preferably, the top of the support platform has three evenly distributed through holes.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, during installation, the worker rotates the second handle, which drives the second threaded rod to rotate, causing the extension plate to move along the placement frame. One end of the extension plate leaves the placement frame, thus adjusting the length. Then, the worker rotates the connecting plate according to the ground inclination at the installation location until the inclination of the connecting plate is the same as the ground. Then, the worker rotates the bolt, which contacts the rotating block. The friction between the two fixes the rotating block. The setting of the rotating shaft and the rotating rod allows the worker to freely adjust the inclination direction of the connecting plate. Finally, the worker continues to rotate the second handle until the connecting plate is in contact with the ground. Then, the worker can use screws to install the plate through the mounting holes on the connecting plate.

[0015] 2. In this utility model, when the operator rotates the second handle, the extension plate moves along the placement frame and drives the slider to slide in the groove. The slider can prevent the extension plate from leaving the placement frame. Attached Figure Description

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1, as Figures 1-5 As shown, this utility model provides a passenger elevator steel cable guiding device, including a support platform 1. Placement frames 2 are fixedly installed at the four corners of the bottom of the support platform 1. An extension plate 10 is slidably installed inside the placement frame 2. A threaded groove 11 is opened at the top of the extension plate 10. A second threaded rod 9 is rotatably installed inside the placement frame 2. The top of the second threaded rod 9 passes through the support platform 1 and is fixedly installed with a second handle 5. The second threaded rod 9 is threadedly connected to the threaded groove 11. A rotating shaft 12 is rotatably installed at the bottom of the extension plate 10. A rotating block 13 is fixedly installed at the bottom of the rotating shaft 12. Rotating rods 14 are fixedly installed at both ends of the rotating block 13. Fixing plates 15 are fixedly installed on opposite sides of the two rotating rods 14. Connecting plates 16 are fixedly installed at the bottom of the two fixing plates 15. A bolt 24 is threadedly connected to the outer wall of one of the two fixing plates 15.

[0025] The effect achieved by the entire embodiment 1 is as follows: During installation, the worker rotates the second handle 5, which drives the second threaded rod 9 to rotate, causing the extension plate 10 to move along the placement frame 2. One end of the extension plate 10 leaves the placement frame 2, thus adjusting the length. Then, the worker rotates the connecting plate 16 according to the ground inclination at the installation position until the inclination of the connecting plate 16 is the same as that of the ground. Then, the worker rotates the bolt 24, which contacts the rotating block 13. The friction between the two fixes the rotating block 13. The setting of the rotating shaft 12 and the rotating rod 14 facilitates the worker to freely adjust the inclination direction of the connecting plate 16. Finally, the worker continues to rotate the second handle 5 until the connecting plate 16 is in contact with the ground. Then, the worker can use screws to install the plate by passing them through the mounting holes on the connecting plate 16.

[0026] Example 2, as Figures 1-5 As shown, further, a groove 17 is provided on the inner wall of the placement frame 2, and a slider 18 is fixedly installed on the outer wall of the extension plate 10. The slider 18 is slidably connected to the groove 17.

[0027] Furthermore, three evenly distributed first fixed seats 20 and three evenly distributed second fixed seats 21 are fixedly installed at the bottom of the support platform 1. A rotating plate 22 is hinged inside the first fixed seat 20 and the second fixed seat 21. A guide wheel 23 is rotatably installed at one end of the rotating plate 22.

[0028] Furthermore, three evenly distributed first threaded rods 6 are rotatably mounted on the bottom of the support platform 1. The top of the first threaded rods 6 passes through the support platform 1 and is fixedly mounted with a first handle 4. A movable frame 8 is threadedly connected to the outer wall of the first threaded rods 6.

[0029] Furthermore, three evenly distributed limiting rods 7 are fixedly installed at the bottom of the support platform 1. The limiting rods 7 pass through the movable frame 8 and are slidably connected to the movable frame 8.

[0030] Furthermore, limit plates 19 are fixedly installed at the bottom of each of the three limit rods 7 to prevent the moving frame 8 from leaving the outer wall of the limit rod 7.

[0031] Furthermore, the top of the support platform 1 has three evenly distributed through holes 3 to facilitate the passage of steel cables.

[0032] The effect achieved by the entire embodiment 2 is that when the operator rotates the second handle 5, the extension plate 10 moves along the placement frame 2, thereby driving the slider 18 to slide in the groove 17. The slider 18 can prevent the extension plate 10 from leaving the placement frame 2.

[0033] Working principle: During installation, the operator rotates the second handle 5, which drives the second threaded rod 9 to rotate, causing the extension plate 10 to move along the placement frame 2. One end of the extension plate 10 leaves the placement frame 2, allowing for length adjustment. Then, the operator rotates the connecting plate 16 according to the ground inclination at the installation location until the inclination of the connecting plate 16 is the same as the ground. Then, the operator rotates the bolt 24, which contacts the rotating block 13. The friction between the bolt and the rotating block 13 fixes the rotating block 13 in place. The setting of the rotating shaft 12 and the rotating rod 14 allows the operator to freely adjust the inclination direction of the connecting plate 16. Finally, the operator continues to rotate the second handle 5 until the connecting plate 16 is flush with the ground. Then, the operator can use screws to install the plate through the mounting holes on the connecting plate 16. When the operator rotates the second handle 5, the extension plate 10 moves along the placement frame 2, which in turn causes the slider 18 to slide within the groove 17. The slider 18 prevents the extension plate 10 from leaving the placement frame 2. During the guiding process, the worker passes the steel cable through the through hole 3, and then the worker rotates the first handle 4, the first threaded rod 6 rotates, the moving frame 8 rises, and the moving frame 8 pushes the two rotating plates 22 to rotate, and the two guide wheels 23 move closer to each other until the opposite sides of the two guide wheels 23 are in contact with the steel cable, thus completing the guiding of the steel cable.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
