Abstract
Description
Technical Field
[0001] This utility model relates to the field of hydraulic integration technology, specifically to a hydraulic integration system for scissor lift platforms. Background Technology
[0002] Scissor lift platforms are widely used in industry, construction, logistics, and other fields to lift and move goods. The hydraulic system, as the core drive component of the scissor lift platform, directly affects the platform's performance, ease of maintenance, and space utilization.
[0003] Traditional scissor lift hydraulic integrated systems typically have the hydraulic pump and drive unit fixedly mounted inside the base or support frame. While this design simplifies the structure to some extent, it still presents problems in practical use: When the scissor lift base is designed to be movable, the traditional hydraulic integrated system is fixedly located inside the base, making it difficult to efficiently maintain and repair the internal hydraulic integrated system. On the other hand, when the scissor lift base is designed to be immovable, the traditional hydraulic integrated system is located on the outside of the base and can be moved around. While this facilitates maintenance and repair, it occupies space and results in messy wiring and piping. Consequently, it is impossible to reduce space usage and facilitate maintenance and repair when using the scissor lift. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a hydraulic integrated system for scissor lift platforms, solving the problems mentioned in the background section.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic integrated system for a scissor lift platform, comprising a base, a lifting frame at the upper end of the base, a platform fixed at the upper end of the lifting frame, a support frame fixed inside the base, a hydraulic cylinder rotatably connected to the support frame, the output end of the hydraulic cylinder rotatably connected to the lifting frame, a hydraulic integrated mechanism inside the support frame, the hydraulic integrated mechanism comprising an integrated box, a hydraulic pump and a drive motor fixed inside the integrated box, the drive motor driving the hydraulic pump, the hydraulic pump being connected to the hydraulic cylinder, the integrated box being slidably mounted on the support frame and slidable to the outside of the base, an opening being provided on the base, and a sealing plate being fixedly connected to the opening by screws.
[0006] Furthermore, a guide rail is fixedly connected to the support frame, and a limiting groove is formed at the upper end of the guide rail. A bracket is fixedly connected to the lower end of the integrated box, and guide wheels are rotatably connected to both sides of the lower end of the bracket. The guide wheels are located on both sides of the guide rail.

A guide rod is fixedly connected to the middle of the lower end of multiple brackets, and the guide rod is slidably matched with the limiting groove.
[0007] Furthermore, support rods are rotatably connected to both sides of the outer end of the integrated box, and extension rods are threadedly connected to the ends of the support rods, with washers fixed to the ends of the extension rods.
[0008] Furthermore, a fixing plate is fixedly connected to the middle of the outer end of the integrated box, a fixing rod is threadedly connected to the fixing plate, a positioning threaded cylinder is fixedly connected inside the base, and the fixing rod and the positioning threaded cylinder are threadedly connected.
[0009] Furthermore, the base is provided with rollers at the four corners, with two rollers on one side being omnidirectional and two rollers on the other side being fixed, and all rollers can be locked.
[0010] Furthermore, the two side walls of the integrated box are provided with connection holes, and the connecting pipe between the hydraulic pump and the oil cylinder is provided through the connection holes.
[0011] Compared to the aforementioned background technology, the hydraulic integrated system for scissor lift platforms provided in this application includes a hydraulic integrated system that is now very mature in technology, and a hydraulic integrated mechanism as the core component.

[0022] 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.
[0023] Please see Figure 1-7This utility model provides a technical solution: a hydraulic integrated system for a scissor lift platform, including a base 1, a lifting frame 2 at the upper end of the base 1, a platform 3 fixed at the upper end of the lifting frame 2, a support frame 4 fixed inside the base 1, a hydraulic cylinder 5 rotatably connected to the support frame 4, the output end of the hydraulic cylinder 5 rotatably connected to the lifting frame 2, a hydraulic integrated mechanism inside the support frame 4, the hydraulic integrated mechanism including an integrated box 9, a hydraulic pump 11 and a drive motor 10 fixed inside the integrated box 9, the drive motor 10 driving the hydraulic pump 11, the hydraulic pump 11 being connected to the hydraulic cylinder 5, the integrated box 9 being slidably mounted on the support frame 4, and slidable to the outside of the base 1, the base 1 having an opening, and a sealing plate 21 fixedly connected to the opening by screws; the design upgrade is based on existing hydraulic integrated technology. Traditional hydraulic integrated technology designs the hydraulic pump 11 and drive motor 10 in one place for easy maintenance and repair, while the overall position is either fixed or... The traditional hydraulic integrated design has a design flaw when the base 1 is designed to be both movable and fixed. Movable positions take up too much space, while fixed positions are inconvenient for maintenance and repair. Therefore, this design movably mounts the integrated box 9 on the support frame 4 inside the base 1. The hydraulic pump 11, drive motor 10, and other integrated equipment are placed inside the integrated box 9. Since this is existing technology, it will not be described in detail here. After placing all the integrated equipment inside the integrated box 9, the sealing plate 21 can be removed during maintenance and repair through the opening, and then the integrated box 9 can be pulled out. When in use, the integrated box 9 is pushed back into the base 1. This not only takes up little space but also facilitates the maintenance and repair of the hydraulic integrated equipment, improving the overall ease of use and practicality. The hydraulic integrated mechanism drives the cylinder 5, which in turn drives the lifting frame 2 to fold and stretch, which is existing technology and will not be described in detail here.
[0024] like Figure 7 As shown, a guide rail 7 is fixedly connected to the support frame 4. A limiting groove 8 is opened at the upper end of the guide rail 7. A bracket 13 is fixedly connected to the lower end of the integrated box 9. Guide wheels 14 are rotatably connected to both sides of the lower end of the bracket 13. The guide wheels 14 are located on both sides of the guide rail 7. The bracket 13 is set in an inverted "mountain" shape, and the protruding part in the middle is limited and slidably set with the limiting groove 8. The guide rail 7 is matched with the position of the opening. A guide rod 15 is fixedly connected to the middle of the lower end of multiple brackets 13. The guide rod 15 is matched and slidably set with the limiting groove 8. The multiple brackets 13 at the lower end of the integrated box 9 can provide more stable support. The guide wheels 14 are rotatably connected to both sides of the bracket 13. The guide wheels 14 roll with the guide rail 7, and the unique shape of the bracket 13 matches the limiting groove 8 for limited sliding, which makes it more stable when pulling out in front and behind. Under the action of the guide rod 15, it can be pulled more stably, improving the overall support.
[0025] like Figure 6As shown, support rods 16 are rotatably connected to both sides of the outer end of the integrated box 9. An extension rod 17 is threadedly connected to the end of the support rod 16, and a washer is fixed to the end of the extension rod 17. The support rod 16 is rotatably set at the outer end of the integrated box 9. There is a damping force between the support rod 16 and the integrated box 9. The extension rod 17 is threadedly connected to the end of the support rod 16. Depending on different ground and environment, the integrated box 9 can be supported, which facilitates the maintenance and repair of the internal hydraulic integrated mechanism.
[0026] like Figure 6 As shown, a fixing plate 18 is fixedly connected to the middle of the outer end of the integrated box 9. A fixing rod 19 is threadedly connected to the fixing plate 18. A positioning threaded cylinder 20 is fixedly connected inside the base 1. The fixing rod 19 is threadedly connected to the positioning threaded cylinder 20. The fixing plate 18 is fixed at the middle position of the outer side of the integrated box 9. This position not only makes it easy to pull the integrated box 9 outward, but also the fixing rod 19 is threadedly connected to the fixing plate 18. When the integrated box 9 is pushed into the base 1, the fixing rod 19 is rotated downward and threadedly connected to the positioning threaded cylinder 20. In this way, the integrated box 9 will not move due to vibration during the overall operation, and the overall hydraulic integrated mechanism's operating stability is improved.
[0027] like Figure 5 As shown, rollers 6 are provided at the four corners of the base 1. Two rollers 6 on one side are universal, while two rollers 6 on the other side are fixed. The rollers 6 on both sides are elastic rubber wheels. The two rollers 6 on one side are universal to facilitate directional control during movement, while the fixed rollers 6 provide overall stability during movement. This makes the rotation direction more stable during movement, and all rollers 6 can be locked to ensure stability when not moving.
[0028] like Figure 2 As shown, connection holes 12 are provided on both side walls of the integrated box 9. The connecting pipe between the hydraulic pump 11 and the cylinder 5 passes through the connection holes 12. The connection holes 12 can be used to bind the connecting pipe between the hydraulic pump 11 and the cylinder 5 and to organize the internal connecting lines. Not only the connecting pipe between the hydraulic pump 11 and the cylinder 5, but also the connecting line between the cylinder 5 and the overall hydraulic integrated mechanism can pass through the connection holes 12, improving the aesthetics of the overall wiring.
