Description

Technical Field

[0001] This utility model relates to the field of lifting platform technology, and specifically to a lifting platform. Background Technology

[0002] A lifting platform is a type of equipment commonly used in industry, construction, warehousing, and other fields, primarily for lifting and lowering objects vertically. It utilizes electric, hydraulic, or pneumatic power to drive the lifting mechanism, thereby enabling the vertical transport of goods.

[0003] A lifting platform disclosed in CN211867736U includes a base, a working platform located above the base, and a lifting mechanism for adjusting the height of the working platform relative to the base. The lifting mechanism includes at least two vertically arranged adjusting rods, and the base and the working platform are fixedly connected with connecting blocks corresponding to the adjusting rods. Both the upper and lower ends of the adjusting rods are threaded, and the upper and lower connecting blocks are threaded to engage with the threads at the upper and lower ends of the adjusting rods. The threads at the upper and lower ends of the adjusting rods have opposite directions of rotation; or the threads at the upper and lower ends of the adjusting rods have the same direction of rotation but different pitches. This lifting platform adjusts the height of the working platform by rotating the adjusting rods to raise or lower it relative to the base. Furthermore, it has at least two independent adjusting rods, so that when the ground is uneven or the upper surface of the base is uneven, causing the working platform to tilt, the levelness of the working platform can be adjusted by rotating each adjusting rod individually.

[0004] Although the aforementioned patent allows the work platform to be raised or lowered relative to the base by rotating the adjusting rod to adjust the height of the work platform, and it has at least two independent adjusting rods so that the levelness of the work platform can be adjusted by rotating each adjusting rod when the ground or the upper surface of the base is uneven and the work platform is tilted, the device has the following drawbacks in actual use: its structural design results in a relatively high initial height and a large overall size, which causes inconvenience for placing goods on the platform, handling the platform, and utilizing the space.

[0005] Therefore, there is an urgent need for a lifting platform to solve the above problems. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a lifting platform, which can effectively solve the problems of high initial height and large device size in the existing technology.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: a lifting platform, comprising a base, a set of slide rails on the surface of the base, movable seats A slidably connected to the surfaces of two slide rails, a pull rod fixedly connected between the two movable seats A, a set of rotating rods A rotatably connected to the outside of the pull rod, fixed seats A rotatably connected to one end of each of the two rotating rods A, a set of fixed seats B fixedly connected to the surface of the base, rotating rods B rotatably connected to one side of each of the two fixed seats B, movable seats B rotatably connected to one end of each of the two rotating rods B, a bracket slidably connected to the top surface of each of the two movable seats B, and a lifting cylinder fixedly connected to the surface of the base.

[0010] As a further embodiment of this utility model, top plates are fixedly connected to both sides of the bracket, and power-assisted cylinders are fixedly connected to both sides of the base. The two power-assisted cylinders are located directly below the two top plates, and the power-assisted cylinders facilitate the initial lifting and lowering of the platform.

[0011] As a further embodiment of this utility model, the lifting cylinder is fixedly connected to one side of the pull rod, and the pull rod is slidably connected to the surface of the base, so that the lifting cylinder can smoothly pull the pull rod.

[0012] As a further embodiment of this utility model, the inner sidewall of the bracket is rotatably connected to several conveying rollers, and the several conveying rollers are the same size and have equal spacing, which facilitates the movement of goods on the conveying rollers.

[0013] As a further embodiment of this utility model, a set of connecting blocks is fixedly connected to both sides of the base, and a support foot is fixedly connected to the bottom surface of both sets of connecting blocks, which facilitates the fixation of the platform.

[0014] As a further embodiment of this utility model, a rotating shaft is rotatably connected between the two rotating rods A and B, which facilitates the rotation between the rotating rods A and B.

[0015] (III) Beneficial Effects

[0016] This utility model provides a lifting platform, which has the following beneficial effects:

[0017] This lifting platform, through the arrangement of rotating rod A, rotating rod B, lifting cylinder, and assist cylinder, initially has a low height due to the large angle between rotating rod A and rotating rod B, making it easy to place goods. However, when raising the platform, the large angle between rotating rod A and rotating rod B requires the lifting cylinder to provide a large pulling force initially, which can easily damage the lifting cylinder. The assist cylinder helps the lifting cylinder raise the platform in the initial stage, extending the service life of the lifting cylinder. This mechanism has a low initial height, occupies little space, and is easy to use in a wide range of applications. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figures 1 to 2 This utility model provides a technical solution: a lifting platform, including a base 1, a set of slide rails 2 on the surface of the base 1, movable seats A3 slidably connected to the surfaces of the two slide rails 2, a pull rod 4 fixedly connected in the middle of the two movable seats A3, a set of rotating rods A5 rotatably connected to the outside of the pull rod 4, a fixed seat A6 rotatably connected to one end of the two rotating rods A5, a set of fixed seats B7 fixedly connected to the surface of the base 1, a rotating rod B8 rotatably connected to one side of the two fixed seats B7, a movable seat B9 rotatably connected to one end of the two rotating rods B8, a bracket 10 slidably connected to the top surface of the two movable seats B9, and a lifting cylinder 11 fixedly connected to the surface of the base 1. Through the arrangement of rotating rods A5, rotating rods B8, lifting cylinder 11 and assist cylinder 13, the initial height is low, the space occupied is small, and it is easy to use widely.

[0023] Please see Figure 1 The support 10 is fixedly connected to the top plate 12 on both sides, and the base 1 is fixedly connected to the two sides of the assist cylinder 13. The two assist cylinders 13 are located directly below the two top plates 12. The assist cylinders 13 facilitate the initial lifting and lowering of the platform.

[0024] Please see Figure 2 The lifting cylinder 11 is fixedly connected to one side of the pull rod 4, and the pull rod 4 is slidably connected to the surface of the base 1, so that the lifting cylinder 11 can smoothly pull the pull rod 4.

[0025] Please see Figure 1The inner sidewall of the support 10 is rotatably connected to several conveyor rollers 14. The several conveyor rollers 14 are the same size and have equal spacing, which facilitates the movement of goods on the conveyor rollers 14.

[0026] Please see Figure 1 A set of connecting blocks 15 are fixedly connected to both sides of the base 1, and a support foot 16 is fixedly connected to the bottom surface of both sets of connecting blocks 15. The support foot 16 facilitates the fixation of the platform.

[0027] Please see Figure 1 A rotating shaft 17 is rotatably connected between the two rotating rods A5 and B8, which facilitates the rotation between the rotating rods A5 and B8.

[0028] In this invention, the working steps of the device are as follows:

[0029] The goods are placed on the conveyor roller 14, and then the assist cylinder 13 and the lifting cylinder 11 are activated. The lifting cylinder 11 pulls the pull rod 4, and the pull rod 4 drives the moving seat A3 to move on the surface of the base 1. The angle of the rotating rod A5 and the rotating rod B8 is reduced by the movement of the rotating shaft 17 and the moving seat B9, so that the platform rises. The assist cylinder 13 can help raise the platform in the initial stage of the lifting cylinder 11. After the goods are lifted, the angle of the rotating rod A5 and the rotating rod B8 is increased by the movement of the rotating shaft 17 and the moving seat B9, so that the platform falls to the lowest point, reducing the space occupied by the platform. The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
