Description

Technical Field

[0001] This utility model relates to the field of hydraulic manual lifting platform technology, specifically to a hydraulic manual lifting platform for the production of thick coating liquid for non-oriented silicon steel. Background Technology

[0002] The main functions of thick coating liquid for non-oriented silicon steel include improving corrosion resistance, insulation, and mechanical strength. Specifically, the coating liquid forms a protective film to prevent corrosion of the silicon steel sheets during processing and use, while also improving its insulation properties and reducing eddy current losses, thereby improving the efficiency and stability of the motor. A hydraulic lift is required for the coating process. The hydraulic lift primarily achieves its lifting function through the pressure transmission of hydraulic oil. Its scissor-lift mechanism provides high stability during lifting, and its large working platform and high load-bearing capacity allow for a wider range of high-altitude operations and are suitable for multiple people working simultaneously.

[0003] A search revealed existing technology (publication number: CN214218055U), which describes "a hydraulic manual lifting machine for the production of insulating coating liquid for large motors, including a base, with support frames fixed on both sides of the base, and a lifting platform at the top of the base via a hydraulic assembly. The hydraulic assembly includes two U-shaped square tubes, two first sliding plates, and two second sliding plates. The two U-shaped square tubes are fixed on both sides of the top of the base, the two first sliding plates are slidably disposed on one side of the inner wall of the U-shaped square tubes, and the two second sliding plates are slidably disposed on the other side of the inner wall of the U-shaped square tubes. The interior of the U-shaped square tubes is filled with hydraulic oil. The beneficial effects of this utility model are: by rotating the handle of the fine-tuning component, the second gear meshes with the first gear, causing the rectangular threaded tube and the rectangular sleeve to move threadedly. The rectangular sleeve is connected to the second sliding plate, driving it to move up and down. The lifting purpose is achieved by sliding the hydraulic oil with the second sliding plate, while facilitating fine-tuning and making it convenient to use."

[0004] Although the hydraulic manual lift described in the aforementioned patent document achieves manual fine-tuning, it still has some shortcomings: the existing hydraulic manual lift relies entirely on manual operation of the threaded column, which results in low efficiency and high labor intensity when performing lifting operations with a large stroke. Secondly, the two handles involved cannot guarantee synchronous rotation or consistent speed, which leads to different pressures on the lower sides of the first slide plate on both sides. When there are heavy objects on the lifting platform, it cannot maintain stable lifting. Utility Model Content

[0005] To overcome the shortcomings of the existing technology, a hydraulic manual lifting machine for producing thick coating liquid for non-oriented silicon steel is provided to solve the problems mentioned in the background technology.

[0006] To achieve the above objectives, a hydraulic manual lifting machine for producing thick coating liquid for non-oriented silicon steel is provided, comprising: a base, a drive device and a hydraulic assembly on the upper side of the base, the drive device and the hydraulic assembly being connected by a connecting pipe; the drive device including a hydraulic tank, a hand-cranked screw lifting device connected to the upper side of the hydraulic tank, and the lower end of the ball screw inside the hand-cranked screw lifting device being rotatably connected to a first piston plate inside the hydraulic tank; the hydraulic assembly including a base plate, side plates connected to both ends of the base plate, and a sliding plate slidably connected inside the side plates; hydraulic oil being provided inside the base plate, side plates and hydraulic tank; a first platform connected to the upper end of the sliding plate, an electro-hydraulic actuator connected to the lower end of the first platform, and a second platform connected to the upper end of the electro-hydraulic actuator.

[0007] Furthermore, one end of the connecting pipe is connected to the hydraulic tank at the lower side of the first piston plate, while the other end of the connecting pipe is connected to the upper middle part of the base plate.

[0008] Furthermore, the upper end of the hand-cranked screw lifting device is connected to a fixing plate, and the fixing plate is welded to the outer wall of the side plate.

[0009] Furthermore, both the bottom plate and the side plate have internal cavities that are interconnected, and a second piston plate is provided in the inner cavity of the side plate.

[0010] Furthermore, the second piston plate is connected to the lower end of the slide plate, and the upper end of the slide plate is located on the upper side of the side plate. The upper end of the slide plate is fixedly connected to the first platform through a connecting block.

[0011] Furthermore, a synchronization controller is installed on the lower side of the first platform, and the synchronization controller is electrically connected to the electro-hydraulic actuator, which is located between the side plates.

[0012] Furthermore, the piston rod of the electro-hydraulic actuator slides through the first platform, and the upper end of the piston rod is fixedly connected to the bottom of the second platform.

[0013] Furthermore, both the outer edges of the first piston plate and the second piston plate are provided with sealing rings.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. In use, the four electro-hydraulic actuators can be started simultaneously by the synchronous controller to push the second platform upward to the appropriate position. Then, the first piston plate is driven downward by manually operating the hand-cranked screw lifting device. This pushes the hydraulic oil in the hydraulic tank to the bottom plate and side plate through the connecting pipe. The second piston plate inside the side plate is pushed upward, and the first platform is pushed upward by the sliding plate. Since it is a manual operation, the speed of pushing the first platform out is relatively slow, which achieves the effect of fine adjustment. At the same time, during a large lifting stroke, the second platform can be raised to the near position in one go by the electro-hydraulic actuators, thus avoiding the defects of high labor intensity and low efficiency caused by manual operation throughout the process.

[0016] 2. By connecting the base plate and side plates and connecting them to the hydraulic tank through connecting pipes, the movement of hydraulic oil in the two side plates is kept synchronous. That is, the pushing force of the hydraulic oil on the two slide plates is balanced, thereby achieving a relatively stable pushing process of the slide plates. When there are heavy objects on the platform, stable lifting can be guaranteed. Attached Figure Description

[0024] Reference Figures 1 to 5 As shown, this utility model provides a hydraulic manual lifting machine for the production of coating liquid for thick coating of non-oriented silicon steel, including: a base 1, a drive device 2 and a hydraulic component 3 on the upper side of the base 1, and the drive device 2 and the hydraulic component 3 are connected by a connecting pipe 6. The drive device 2 includes a hydraulic tank 21, and a hand-cranked screw lifting device 22 is connected to the upper side of the hydraulic tank 21. The lower end of the ball screw 221 inside the hand-cranked screw lifting device 22 is rotatably connected to the first piston plate 222 inside the hydraulic tank 21. The hydraulic component 3 includes a base plate 31, and side plates 32 are connected to both ends of the base plate 31. A sliding plate 33 is slidably connected inside the side plate 32. Hydraulic oil 35 is provided inside the base plate 31, the side plates 32 and the hydraulic tank 21. A first platform 4 is connected to the upper end of the sliding plate 33, and an electro-hydraulic push rod 8 is connected to the lower end of the first platform 4. A second platform 5 is connected to the upper end of the electro-hydraulic push rod 8.

[0025] In this embodiment, the base 1, drive device 2, hydraulic component 3, first platform 4, second platform 5, and electro-hydraulic actuator 8 constitute the main structure of the hydraulic manual lift for producing non-oriented silicon steel thick coating liquid involved in this application.

[0026] Specifically, the hand-cranked screw jack 22 is a hand-cranked screw jack of the SWL type under the existing technology.

[0027] Specifically, there are four electro-hydraulic actuators 8, which are distributed in a matrix structure on the lower side of the first platform 4 to achieve stable support for the second platform 5.

[0028] like Figures 1 to 5In this configuration, one end of the connecting pipe 6 is connected to the hydraulic tank 21 at the lower side of the first piston plate 222, while the other end of the connecting pipe 6 is connected to the upper middle part of the base plate 31. The upper end of the hand-cranked screw lifting device 22 is connected to a fixing plate 23, which is welded to the outer wall of the side plate 32. Both the base plate 31 and the side plate 32 have internal cavities that are interconnected. A second piston plate 34 is slidably connected within the cavity of the side plate 32 and is connected to the lower end of the sliding plate 33. The upper end of the slide plate 33 is located on the upper side of the side plate 32, and the upper end of the slide plate 33 is fixedly connected to the first platform 4 through the connecting block 36. The outer edges of the first piston plate 222 and the second piston plate 34 are both provided with sealing rings. A synchronization controller 7 is installed on the lower side of the first platform 4, and the synchronization controller 7 is electrically connected to the electro-hydraulic push rod 8. The electro-hydraulic push rod 8 is located between the side plates 32. The piston rod of the electro-hydraulic push rod 8 slides through the first platform 4, and the upper end of the piston rod is fixedly connected to the bottom of the second platform 5.

[0029] Specifically, the ball screw 221 rotates through the fixed plate 23, and a screw sleeve is provided on the upper side of the fixed plate 23, that is, the ball screw 221 rotates and moves up and down inside the screw sleeve.

[0030] Specifically, the connecting pipe 6 is attached to the upper side of the base plate 31 and passes around the side plate 32.

[0031] Specifically, the inner cavities of the base plate 31 and the side plate 32 form a U-shaped cavity structure.

[0032] In use, the four electro-hydraulic actuators can be activated simultaneously using a synchronous controller to push the second platform upwards to the appropriate position. Then, the first piston plate is driven downwards by manually operating the hand-cranked screw lifting device, which in turn pushes the hydraulic oil inside the hydraulic tank through the connecting pipe to the bottom plate and side plate. This pushes the second piston plate inside the side plate upwards, causing the first platform to be pushed upwards via the sliding plate. Because it is a manual operation, the speed at which the first platform is pushed out is relatively slow, allowing for fine-tuning. At the same time, during a large lifting stroke, the second platform can be raised to the near position in one go using the electro-hydraulic actuators, thus avoiding the high labor intensity and low efficiency caused by requiring manual operation throughout the process.

[0033] The hydraulic manual lifting platform for the production of non-oriented silicon steel thick coating liquid of this utility model can effectively solve the problems mentioned in the background technology. It achieves the effect of finely adjusting the position of the lifting platform, high operating efficiency, reduced labor intensity, and stable lifting effect on the basis of the existing hydraulic manual lifting platform technology for the production of non-oriented silicon steel thick coating liquid.
