Description

Technical Field

[0001] This utility model relates to the field of lifting platform technology, and in particular to an electric lifting platform. Background Technology

[0002] A lifting platform is a multi-functional lifting and loading / unloading machine widely used in industrial, commercial, and construction fields for the vertical transportation of goods or personnel. Lifting platforms are mainly divided into hydraulic and electric types. Hydraulic lifting platforms use changes in hydraulic oil pressure to lift goods, featuring high load-bearing capacity and stability, making them suitable for handling heavy goods and high-altitude operations. Electric lifting platforms are driven by a motor, are easy to operate, and are suitable for handling light goods; however, existing electric lifting platforms have relatively weak load-bearing capacity, limiting the weight of goods they can handle, necessitating improvements to their load-bearing structure. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems mentioned in the background art.

[0004] The present invention adopts the following technical solution: an electric lifting platform, including a base plate, a servo motor fixedly installed on one side of the base plate, a coupling fixedly installed on the output end of the servo motor, a ball screw fixedly connected to one side of the coupling, a nut seat threadedly connected to the surface of the ball screw, a slide fixedly installed on one side of the nut seat, a slider fixedly installed at the bottom of the slide, and a guide rail fixed to the base plate slidably connected inside the slider.

[0005] Preferably, a sloping rail is fixedly installed on the upper surface of the slide table, a small slide table is slidably connected to the surface of the sloping rail, and a platform is fixedly installed on the upper surface of the small slide table.

[0006] Preferably, side plates are fixedly installed at the front and rear of the base plate, and lifting rings are fixedly installed on the upper surface of the base plate near the side plates.

[0007] Preferably, the lifting rings are arranged in pairs on the upper surface of the base plate.

[0008] Preferably, the guide rail and the slider are symmetrically arranged on the lower surface of the slide table.

[0009] Preferably, two elongated grooves are formed on the upper surface of the platform.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] In this invention, a servo motor drives a coupling to rotate a ball screw. When the ball screw rotates, it causes the nut seat to move along the axial direction of the ball screw. The linear motion of the nut seat pushes the slide table to move on the guide rail, thereby forcing the small slide table to move obliquely upward on the inclined rail, achieving the purpose of lifting and lowering the platform. By pushing the small slide table obliquely on the surface of the inclined rail from the side, the conventional longitudinal lifting motion is changed into oblique pushing lifting, which improves the load-bearing capacity of the platform, thus enabling the lifting and lowering of heavier goods through electric drive.

[0017] 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.

[0018] 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.

[0019] Example

[0020] Please see Figure 1-3This utility model provides a technical solution: an electric lifting platform, including a base plate 1, a servo motor 2 fixedly installed on one side of the base plate 1, a coupling 3 fixedly installed at the output end of the servo motor 2, the main function of the coupling 3 is to connect the motor shaft and the ball screw 12 so that they can rotate together and transmit torque, the ball screw 12 is fixedly connected to one side of the coupling 3, the surface of the ball screw 12 is threadedly connected to a nut seat 4, a slide table 5 is fixedly installed on one side of the nut seat 4, a slider 6 is fixedly installed at the bottom of the slide table 5, a guide rail 7 fixed to the base plate 1 is slidably connected inside the slider 6, an inclined rail 8 is fixedly installed on the upper surface of the slide table 5, a small slide table 9 is slidably connected to the surface of the inclined rail 8, and a platform 10 is fixedly installed on the upper surface of the small slide table 9;

[0021] Side plates 11 are fixedly installed at the front and rear of the base plate 1, and lifting rings 13 are fixedly installed on the upper surface of the base plate 1 near the side plates 11. The lifting rings 13 are used to lift the entire platform. The lifting rings 13 are arranged in pairs on the upper surface of the base plate 1. Four lifting rings 13 make the platform more stable. The guide rail 7 and the slider 6 are symmetrically arranged on the lower surface of the slide table 5. Two long grooves are opened on the upper surface of the platform 10. The long grooves are used to reduce the weight of the platform 10 and to facilitate the use of ropes to tie and fix some goods.

[0022] Working principle: The servo motor 2 drives the coupling to rotate the ball screw 12. When the ball screw 12 rotates, it drives the nut seat 4 to move along the axis of the ball screw 12. The linear motion of the nut seat 4 pushes the slide table 6 to move on the guide rail 7, thereby forcing the small slide table 9 to move obliquely upward on the inclined rail 8, so as to drive the platform 10 to rise and fall.
