Technical Field

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

[0002] Lifting equipment is widely used in industrial production, warehousing and logistics, and construction. Traditional lifting platforms mostly adopt a fixed structure, which is easily contaminated by dust and debris during the lifting process, affecting the equipment's lifespan and operational safety. In addition, existing lifting platforms often have limited functionality and cannot achieve horizontal rotation adjustment, resulting in poor flexibility of use. Although some equipment has attempted to incorporate dustproof or rotation functions, problems such as complex structure, inconvenient maintenance, and unsatisfactory dustproof effects still exist. Utility Model Content

[0006] The placement rack includes a connecting plate that slides on the lifting frame. A dust cover is provided on the side of the connecting plate away from the lifting frame. Dustproof cloth guide wheels are symmetrically arranged on the inner walls of the dust cover near the connecting plate, and the dustproof cloth passes through the dustproof cloth guide wheels.

[0010] In addition, a preferred structure is that slide rails are symmetrically arranged on the front surface of the lifting frame, and sliders are symmetrically slidably fitted on the slide rails on both sides. The sliders are installed on the surface of the connecting plate away from the placement frame.

[0011] Furthermore, in a preferred configuration, the lifting mechanism includes a lifting servo motor assembly and a ball screw. The ball screw is vertically rotatably mounted on the frame between the two slide rails of the lifting frame, and the lifting servo motor assembly is vertically mounted on the side of the lifting frame away from the ball screw.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-6 The lifting platform includes a rotating base 1, a vertically mounted lifting frame 8 on the rotating base 1, a vertically mounted lifting mechanism 7 on the lifting frame 8, and a vertically sliding placement frame 3 on the lifting frame 8. The placement frame 3 is vertically displaced on the lifting frame 8 by the drive of the lifting mechanism 7. A dustproof cloth 9 is provided on the upper surface of the rotating base 1 and outside the lifting frame 8. The upper and lower ends of the dustproof cloth 9 are fixedly connected to the upper and lower ends of the front surface of the outer shell 2. The placement frame 3 is vertically sliding on the front surface of the outer shell 2. The placement frame 3 includes a connecting plate 31, which is slidably fitted on the lifting frame 8. A dust cover 32 is provided on the side of the connecting plate 31 away from the lifting frame 8. Dustproof cloth guide wheels 33 are symmetrically arranged on the inner walls of the dust cover 32 near the connecting plate 31. The dustproof cloth 9 passes through the dustproof cloth guide wheels 33, and the dustproof cloth 9 can effectively prevent dust.

[0023] The dust cover 32 is horizontally fixed to a connecting bracket 34 at the end away from the connecting plate 31. Placement rods 35 are provided at both ends of the connecting bracket 34, and the placement rods 35 effectively suspend items.

[0024] In addition, an external toothed rotary support base 11 is rotatably mounted on the upper surface of the rotating base 1, and the lifting frame 8 is mounted on the upper surface of the external toothed rotary support base 11. A rotary servo motor assembly 6 is mounted on one side of the lifting frame 8 on the upper surface of the external toothed rotary support base 11. A gear disk 12 that meshes with the external toothed rotary support base 11 is assembled and connected to the bottom output end of the rotary servo motor assembly 6. The rotary servo motor assembly 6 realizes the rotation of the external toothed rotary support base 11, which can realize the rotation of the lifting frame 8 around the rotating base 1 as the axis.

[0025] Meanwhile, a motor cover 5 is provided on the rear surface of the outer shell 2, a control panel 4 is provided on the side of the outer shell 2 adjacent to the motor cover 5, a sheet metal cover 01 is provided on the outside of the rotating base 1, and a control box 02 is provided on the lifting frame 8 above the lifting mechanism 7.

[0026] Among them, slide rails 81 are symmetrically arranged on the front surface of the lifting frame 8, and sliders 82 are symmetrically slidably fitted on the slide rails 81 on both sides. The sliders 82 are installed on the side surface of the connecting plate 31 away from the placement frame 3, and the slide rails 81 ensure the vertical displacement of the placement frame 3.

[0027] Meanwhile, the lifting mechanism 7 includes a lifting servo motor assembly 71 and a ball screw 73. The ball screw 73 is vertically rotatably mounted on the frame of the lifting frame 8 located between the slide rails 81 on both sides. The lifting servo motor assembly 71 is vertically mounted on the side of the lifting frame 8 away from the ball screw 73.

[0028] In addition, a first sprocket 72 is mounted and connected to the bottom output end of the lifting servo motor assembly 71, and a second sprocket 74 is mounted and connected to the bottom of the ball screw 73. The first sprocket 72 and the second sprocket 74 are located on the same plane. A slide block 75 is slidably fitted on the ball screw 73. The slide block 75 is connected to the connecting plate 31. A chain is sleeved on the outside of the first sprocket 72 and the second sprocket 74. Through chain transmission, the lifting servo motor assembly 71 drives the ball screw 73 to rotate.

[0029] In this embodiment, when lifting or lowering an item, the item can be suspended on the placement rod 35. When lifting or lowering the placement rod 35, the lifting servo motor assembly 71 is driven to rotate, and the first sprocket 72 works with the chain to make the second sprocket 74 rotate synchronously, thereby making the ball screw 73 rotate. This allows the slide block 75 to work with the slider 82 to lift or lower the connecting plate 31. The dustproof cloth 9 passes through the dustproof cloth guide wheel 33, so that when the front placement rack 3 is lifted or lowered, the front of the outer shell 2 does not need to be opened. Furthermore, the rotation servo motor assembly 6 can be driven to rotate the gear disk 12, thereby causing the external gear rotary support base 11 to rotate around its axis, adjusting the orientation of the placement rod 35.

[0030] In this utility model, by setting up a dustproof cloth 9 and a dustproof cover 32, and setting a dustproof cloth guide wheel 33 inside the dustproof cover, dust can be effectively prevented from entering the equipment and the service life of the equipment can be extended. The sliding structure of the slide rail 81 and the slider 82 is adopted, combined with the ball screw 73 and the lifting servo motor assembly 71 for driving. The lifting process is stable and reliable. The gear disk 12 is driven by the rotary servo motor assembly 6 to mesh with the external gear rotary support base 11, so as to realize the horizontal rotation of the entire lifting frame 8, which is convenient for multi-directional operation.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
