Description

Technical Field

[0001] This utility model relates to the field of elevator guide rails, and in particular to an adjustable positioner for connecting elevator guide rails. Background Technology

[0002] Elevator guide rails are rigid metal components that guide the movement of elevator cars, counterweights, and other parts. They are mostly T-shaped or have a similar cross-section and require multiple sections to be joined together to form a complete guide path. The quality of this joining directly affects the smoothness of operation. They can be precisely spliced ​​inside the shaft or prefabricated and joined outside the shaft for overall installation. Elevator guide rail joining positioners are designed for both scenarios, assisting in calibrating the position of the joining ends to ensure that guide rails of different specifications are joined flush and securely, improving installation efficiency and accuracy, and adapting to diverse joining requirements inside and outside the shaft.

[0003] However, current elevator guide rail docking positioners have the following drawbacks: First, they lack versatility, cannot adapt to guide rails of different sizes, have a limited fixing range, and are difficult to meet the docking needs of various guide rail specifications. Second, they lack stability, cannot effectively maintain a horizontal state, and are prone to wobbling on uneven installation surfaces, affecting positioning accuracy and operational reliability. In response to this technical problem, this application proposes an adjustable positioner for elevator guide rail docking. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an adjustable positioner for elevator guide rail docking. The aim is to enable the positioner to fix guide rails of different sizes, improve the positioner's versatility, and allow the positioner to remain horizontal, adapting to installation surfaces with different flatness, thereby increasing the stability of the positioner during operation.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An adjustable positioner for elevator guide rail docking includes a base plate. Rotary rods are rotatably connected to the four corners of the top side of the base plate. An eccentric wheel for clamping the guide rail is fixedly connected to the top of each rotating rod. A rubber ring is fixedly connected to the outer wall of the eccentric wheel. A rotating assembly is installed inside the base plate to drive the eccentric wheel to rotate. A level is installed on the front side of the top side of the base plate. Metal plates are connected to the four corners of the bottom side of the base plate via lifting assemblies to adjust the height of the metal plates. A handle is fixedly connected to the right side of the base plate.

[0006] Furthermore, the rotating assembly includes a gear fixedly connected to the outer wall of the rotating rod, and racks are slidably connected to the four corners inside the base plate, with the gear and racks meshing with each other.

[0007] Furthermore, each of the four corners inside the base plate is rotatably connected to a first threaded rod, and the rack is threadedly connected to the outer wall of the first threaded rod.

[0008] Furthermore, two first knobs are rotatably connected to the left and right sides of the base plate via damping shafts, and the end of the first threaded rod is fixedly connected to the inside of the first knob.

[0009] Furthermore, the lifting assembly includes lifting rods slidably connected to the four corners inside the base plate, and the bottom end of the lifting rods is fixedly connected to the top side of the metal plate.

[0010] Furthermore, four protruding strips are fixedly connected to the outer wall of the lifting rod. The protruding strips are slidably connected to the inside of the base plate, and the bottom end of the protruding strips is fixedly connected to the top side of the metal plate.

[0011] Furthermore, a second threaded rod is rotatably connected to each of the four corners inside the base plate, and a second knob is rotatably connected to each of the four corners on the top side of the base plate via a damping shaft. The top end of the second threaded rod is fixedly connected to the inside of the second knob.

[0012] This utility model has the following beneficial effects: In this invention, the rack is driven to slide by the first threaded rod, which in turn drives the gear to rotate the rotating rod, thereby causing the eccentric wheel to rotate. This allows the distance between the edge of the eccentric wheel and the guide rail to be adjusted, enabling the positioner to fix guide rails of different sizes and improving the versatility of the positioner. In this invention, the lifting rod is driven by the second threaded rod to move the protrusion and the metal plate up and down, thereby adjusting the height of the metal plate and leveling the base plate. This allows the positioner to remain horizontal, adapt to different flatness of the mounting surface, and increase the stability of the positioner during operation. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Reference Figures 1-3 This utility model provides an embodiment of an adjustable positioner for elevator guide rail docking, comprising a base plate 3. Rotating rods 7 are rotatably connected to the four corners of the top side of the base plate 3. An eccentric wheel 2 for clamping the guide rail is fixedly connected to the top of each rotating rod 7. The rotating rods 7 drive the eccentric wheel 2 to rotate, causing the edge of the eccentric wheel 2 to move closer to the guide rail, thus clamping the guide rail. A rubber ring 4 is fixedly connected to the outer wall of the eccentric wheel 2 to increase the friction between the eccentric wheel 2 and the guide rail, thereby increasing the clamping force and preventing damage to the guide rail by the eccentric wheel 2. A level 1 is installed on the front side of the top side of the base plate 3 to detect the levelness of the base plate 3. Metal plates 6 are connected to the four corners of the bottom side of the base plate 3, and a handle 5 is fixedly connected to the right side of the base plate 3 for easy carrying of the positioner by personnel. A gear 8 is fixedly connected to the outer wall of the rotating rod 7. A rack 9 is slidably connected to each of the four corners inside the base plate 3. The gear 8 and the rack 9 mesh with each other. A first threaded rod 10 is rotatably connected to each of the four corners inside the base plate 3. The rack 9 is threadedly connected to the outer wall of the first threaded rod 10. Two first knobs 11 are rotatably connected to the left and right sides of the base plate 3 through damping shafts. The end of the first threaded rod 10 is fixedly connected to the inside of the first knob 11. By rotating the first knob 11, the first threaded rod 10 is rotated, which drives the rack 9 to slide, thereby driving the gear 8 to drive the rotating rod 7 to rotate, thus causing the eccentric wheel 2 to rotate. This adjusts the distance between the edge of the eccentric wheel 2 and the guide rail, allowing the positioner to fix guide rails of different sizes and improving the versatility of the positioner.

[0017] Reference Figure 1 , Figure 2 and Figure 4A lifting rod 12 is slidably connected to the four corners inside the base plate 3. The bottom end of the lifting rod 12 is fixedly connected to the top side of the metal plate 6. Four protruding strips 13 are fixedly connected to the outer wall of the lifting rod 12. The protruding strips 13 are slidably connected to the inside of the base plate 3. The bottom end of the protruding strips 13 is fixedly connected to the top side of the metal plate 6. A second threaded rod 14 is rotatably connected to each of the four corners inside the base plate 3. A second knob 15 is rotatably connected to each of the four corners on the top side of the base plate 3 via a damping shaft. The top end of the second threaded rod 14 is fixedly connected to the inside of the second knob 15. By rotating... The second knob 15 rotates the second threaded rod 14, which drives the lifting rod 12 to move the convex strip 13 and the metal plate 6 up and down, thereby adjusting the height of the metal plate 6 and leveling the base plate 3. This allows the positioner to remain horizontal, adapting to mounting surfaces with different flatness and increasing the stability of the positioner during operation. The damping shaft in this design is designed to withstand vibrations generated during use to prevent the corresponding structure from rotating. This design is mainly for guide rails that are docked outside the shaft.

[0018] Working principle: First, place the base plate 3 on the mounting surface, then observe the level 1 to determine the levelness of the base plate 3. Adjust the height of the four corners of the base plate 3 according to the level 1 to keep it level. When leveling the base plate 3 is required, rotate the second knob 15 to rotate the second threaded rod 14, which drives the lifting rod 12 to move the protrusion 13 and metal plate 6 up and down, thereby adjusting the height of the metal plate 6 and leveling the base plate 3. This ensures the positioner remains level. Next, place the two guide rails on the base plate 3, positioning them between the four eccentric wheels 2. Then, rotate the first knob 11 to rotate the first threaded rod 10, which drives the rack 9 to slide, thereby driving the gear 8 to rotate the rotating rod 7. This causes the eccentric wheels 2 to rotate, allowing their edges to fit against the sides of the guide rails, thus fixing the guide rails in place. The guide rails can then be connected.

[0019] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
