Abstract

This utility model discloses a lifting platform with an extended platform, relating to the field of lifting platform technology. It includes a support plate, a fixed plate on top of the support plate, a telescopic assembly on the inner wall of the fixed plate, an extension plate on the outer wall of the fixed plate, and a reinforcing assembly on top of the support plate. The telescopic assembly includes a main rod base, which is fixedly connected to the inner wall of the fixed plate. This lifting platform with an extended platform, by starting a dual-axis motor to drive a threaded rod to rotate, utilizes the threaded transmission principle to ensure that the threaded slide, guided by the slide rod, makes stable and precise linear motion along the axial direction, effectively preventing rotation or deviation and ensuring smooth and reliable telescopic movement.

[0002] A lifting platform is a mechanical device used for vertically lifting personnel or goods. It plays a crucial role in many fields such as construction, logistics, and warehousing. On construction sites, construction lifting platforms are indispensable "helpers," quickly and safely transporting workers and building materials to work surfaces at different heights, greatly improving construction efficiency and shortening project cycles. Their robust structure and reliable safety devices provide strong protection for the lives of construction workers. In logistics and warehousing centers, freight elevators enable the rapid transfer of goods between different floors, optimizing the utilization of storage space and reducing manual handling costs. Lifting platforms come in various types, including fixed and mobile models, allowing for flexible selection based on different scenario requirements. In terms of operation, modern lifting platforms are mostly equipped with intelligent control systems, making operation simple and precise. With continuous technological advancements, lifting platforms are developing towards greater safety, efficiency, and energy conservation, providing better solutions for vertical transportation in various industries.

[0003] However, existing lifts without extendable platforms have significant shortcomings. Their operating range is limited, and the fixed platform size makes it difficult to flexibly extend and cover large areas or long distances. This requires multiple moves of equipment, increasing operation time and labor costs. Therefore, we need a lift with an extendable platform. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lifting platform with an extended platform, comprising a support plate, characterized in that: a fixed plate is provided on the top of the support plate, a telescopic assembly is provided on the inner wall of the fixed plate, an extension plate is provided on the outer wall of the fixed plate, a reinforcing assembly is provided on the top of the support plate, the telescopic assembly includes a main rod base, and the main rod base is fixedly connected to the inner wall of the fixed plate, a threaded rod is movably connected to the inner wall of the main rod base, a dual-axis motor is fixedly connected to one end of the threaded rod, a threaded slide is threadedly connected to the outer wall of the threaded rod, a slide rod is fixedly connected to the inner wall of the main rod base, and a linkage bracket is fixedly connected to one side of the threaded slide.

A base connecting block is fixedly connected to the top of the support base. A fixed motor is fixedly connected to one side of the base connecting block.

[0012] Compared with the prior art, the beneficial effects of this utility model are: this is a lift with an extended platform, (1) By starting the dual-axis motor to drive the threaded rod to rotate, the threaded slide block can make stable and precise linear motion along the axis under the guidance of the slide rod, effectively preventing rotation or deviation, and ensuring smooth and reliable telescopic action. The linkage bracket connects the threaded slide block and the extension plate to realize motion transmission, so that the extension plate can extend and retract synchronously with the slide block.

[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] This utility model embodiment provides a lift with an extended platform, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the system includes a support plate 1, a fixed plate 2 on top of the support plate 1, a telescopic assembly 3 on the inner wall of the fixed plate 2, an extension plate 4 on the outer wall of the fixed plate 2, and a reinforcing assembly 5 on top of the support plate 1. The telescopic assembly 3 includes a main rod base 301, which is fixedly connected to the inner wall of the fixed plate 2. A threaded rod 302 is movably connected to the inner wall of the main rod base 301. A dual-axis motor 303 is fixedly connected to one end of the threaded rod 302. A threaded slide 304 is threadedly connected to the outer wall of the threaded rod 302. A slide rod 305 is fixedly connected to the inner wall of the main rod base 301. A linkage bracket 306 is fixedly connected to one side of the threaded slide 304. By starting the dual-axis motor 303, the threaded rod 302 is rotated, allowing the threaded slide 304 to engage with the external thread of the threaded rod 302 through its internal thread. In conjunction with the rotation of the threaded rod 302, the threaded slide 304, constrained by the slide rod 305 and its own structure, can move linearly along the axial direction of the threaded rod 302. When the threaded rod 302 rotates clockwise, the threaded slide 304 moves in one direction along the threaded rod, and when it rotates counterclockwise, it moves in the opposite direction. The linkage bracket 306 is connected to the threaded slide 304, so that when the threaded slide 304 moves linearly on the threaded rod 302, it will drive the linkage bracket 306 to move together, thereby driving the extension plate 4 to move linearly in sync. This allows the extension plate 4 to extend and retract, so that when the slide moves outward, the extension plate 4 extends, and when the slide moves inward, the extension plate 4 retracts. Thus, the platform at the top of the elevator can be extended and adjusted according to the daily needs of the personnel.

[0017] Further as Figure 2 As shown, the dual-axis motor 303 forms a threaded transmission structure with the threaded rod 302 and the threaded slide 304. The output shaft of the dual-axis motor 303 is fixedly connected to the end of the threaded rod 302, and the external thread of the threaded rod 302 is connected to the internal thread of the threaded slide 304. With the dual-axis motor 303, when the dual-axis motor 303 is started, it can drive the threaded rod 302 to rotate, and when the threaded rod 302 rotates, it can drive the threaded slide 304 to move left and right.

[0018] Further as Figure 2 As shown, the threaded slide 304 forms a fixed structure with the extension plate 4 through the linkage bracket 306, and one side of the threaded slide 304 is fixedly connected to one end of the linkage bracket 306, and the other end of the linkage bracket 306 is fixedly connected to one side of the inner wall of the extension plate 4. When the threaded slide 304 slides, it can drive the linkage bracket 306 to move, and when the linkage bracket 306 moves, it can drive the extension plate 4 to move.

[0019] Further as Figure 2As shown, the main rod base 301 forms a sliding structure with the slide rod 305 and the threaded slide block 304. The inner wall of the main rod base 301 is fixedly connected to one end of the slide rod 305, and the outer wall of the slide rod 305 is slidably connected to the inner wall of the threaded slide block 304. The threaded slide block 304 can slide on the slide rod 305, which facilitates the extension plate 4 to extend and retract.

[0020] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the reinforcement component 5 includes a support base 501, the bottom of which is fixedly connected to the top of the support plate 1. A base connecting block 502 is fixedly connected to the top of the support base 501. A fixed motor 503 is fixedly connected to one side of the base connecting block 502. The output shaft of the fixed motor 503 is fixedly connected to a movable rod 504 via a coupling. A rope wheel rotating shaft 505 is fixedly connected to one end of the movable rod 504. A telescopic traction rope 506 is movably connected to the outer wall of the rope wheel rotating shaft 505. A steering guide rope frame 507 is fixedly connected to one end of the telescopic traction rope 506. A rope end fixing device is fixedly connected to one side of the steering guide rope frame 507. The fixed pin 508, by activating the fixed motor 503, can drive the movable rod 504 to rotate. The movable rod 504 is fixedly connected to the rope wheel rotation shaft 505, which allows the movable rod 504 to rotate. By winding and unwinding the telescopic traction rope 506 wound on it, the tension can be controlled. When the movable rod 504 rotates forward, the rope wheel rotation shaft 505 simultaneously winds up the telescopic traction rope 506, which pulls the extension plate 4 for support. When it rotates backward, the telescopic traction rope 506 is released, allowing it to relax. After the extension plate 4 is adjusted, it can be easily tightened by relying on the telescopic traction rope 506, thus improving the reinforcement stability of the extension plate 4.

[0021] Further as Figure 4 As shown, the fixed motor 503 forms a rotating structure with the rope wheel rotation shaft 505 via the movable rod 504. The output shaft of the fixed motor 503 is fixedly connected to one end of the movable rod 504, and one side of the movable rod 504 is fixedly connected to the inner wall of the rope wheel rotation shaft 505. With the fixed motor 503, when the fixed motor 503 is started, it can drive the movable rod 504 to rotate, and when the movable rod 504 rotates, it can drive the rope wheel rotation shaft 505 to rotate.

[0022] Further as Figure 4As shown, the telescopic traction rope 506 forms a rotating structure with the steering guide rope frame 507 and the rope end fixing pin 508. One end of the telescopic traction rope 506 is fixedly connected to the outer wall of the steering guide rope frame 507, and one side of the steering guide rope frame 507 is fixedly connected to one side of the rope end fixing pin 508. With the steering guide rope frame 507, when the steering guide rope frame 507 rotates, it can drive the telescopic traction rope 506 to wind around the steering guide rope frame 507, which can fix the extension plate 4.

[0023] Working Principle: By starting the dual-axis motor 303, the threaded rod 302 is rotated, allowing the threaded slide 304 to engage with the external thread of the threaded rod 302 through its internal thread. When the threaded rod 302 rotates, the threaded slide 304, constrained by the slide rod 305 and its own structure, moves linearly along the axial direction of the threaded rod 302. Clockwise rotation of the threaded rod 302 causes the threaded slide 304 to move in one direction along the threaded rod, and counterclockwise rotation causes it to move in the opposite direction. Connected to the linkage bracket 306, the linear motion of the threaded slide 304 on the threaded rod 302 causes the linkage bracket 306 to move as well, thereby causing the extension plate 4 to move synchronously in a linear motion, allowing the extension plate 4 to advance... The telescopic mechanism allows the extension plate 4 to extend when the slide moves outward and retract when the slide moves inward. This allows for adjustment of the platform at the top of the elevator according to the daily needs of users. By activating the fixed motor 503, the movable rod 504 can be rotated. The movable rod 504 is fixedly connected to the rope wheel shaft 505, allowing it to rotate. The tension is controlled by winding and unwinding the telescopic traction rope 506 wound around it. When the movable rod 504 rotates forward, the rope wheel shaft 505 simultaneously winds up the telescopic traction rope 506, pulling the extension plate 4 for support. When it rotates backward, the telescopic traction rope 506 is released, allowing it to relax. After the extension plate 4 is adjusted, it can be easily tightened by the telescopic traction rope 506, improving the stability of the extension plate 4.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
