Description

TECHNICAL FIELD

[0001] The utility model relates to hydraulic elevator technical field, concretely relates to a hydraulic elevator. BACKGROUND

[0002] The hydraulic elevator is mainly driven by the pressure of hydraulic oil to realize the function of lifting, and the scissor mechanical structure makes the lifting machine have high stability, wide operation platform and high carrying capacity, so that the high-altitude operation range is larger and multiple people can work at the same time, and the high-altitude operation efficiency is higher and the safety is more guaranteed.

[0003] The hydraulic elevator disclosed by Chinese patent application file CN220999162U comprises an elevator body, and a rotating mechanism is arranged on the outer wall of the elevator body. The rotating mechanism enables the elevator body to be stably supported on a rugged road surface. The rotating mechanism comprises a fixed component, a driven component, a driving component and a limiting component. The driving component in a moving state drives the driven component and the fixed component to rotate synchronously. The utility model sets the rotating mechanism, pulls the rack to slide along the sliding groove, drives the gear to rotate synchronously through the sliding of the rack, drives the rotating shaft, the fixed block, the hydraulic cylinder and the supporting leg to rotate and tilt synchronously through the rotation of the gear, and clamps the limiting block into the corresponding insertion hole when the inclination angle of the supporting leg is consistent with the ground, thereby completing the limiting and fixing of the supporting leg, enabling the supporting leg to completely adhere to the ground on a rugged ground, and improving the stability of the ground support of the elevator body on a rugged road surface.

[0004] However, the rotation angle range of the supporting leg is limited by the interval of the insertion holes. Only when the interval of the insertion holes is denser, the rotation angle range of the supporting leg is wider. Specifically, when the interval of the insertion holes is A1, the rotation angle of the supporting leg is B1 when the limiting block moves by one insertion hole, and when the interval of the insertion holes is A2, the rotation angle of the supporting leg is B2 when the limiting block moves by one insertion hole. If A1>A2, B1>B2. Therefore, if the rotation angle of the supporting leg needs to be adjusted accurately, the interval of the insertion holes should be denser. Although the accurate adjustment of the rotation angle of the supporting leg is realized, the manual adjustment of the rack with small displacement brings about the complexity of operation.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example

[0023] The present invention will now be further described with reference to the accompanying drawings.

[0024] like Figures 1 to 5 As shown, this embodiment provides a hydraulic lift, including a lift body 1 and outrigger assemblies 2 installed near the four corners of the lift body 1. It also includes an adjustment assembly 3 installed on the side of the lift body 1 and used to adjust the tilting angle of the outrigger assemblies 2. The adjustment assembly includes a fixing block 31 and outrigger assemblies 2 installed on the fixing block 31. The fixing block 31 is rotatably installed on the side of the lift body 1 via a mounting shaft 32. The mounting shaft 32 is equipped with a spur gear 33 and a spur gear 34 of different diameters. The adjustment block 35 is slidably installed on the side of the lift body 1 and located below the mounting shaft 32. The adjustment block 35 is equipped with a rack 36 adapted to the spur gear 33 and a rack 37 adapted to the spur gear 34.

[0025] The working principle and beneficial effects of the above technical solution are as follows:

[0026] This utility model discloses a hydraulic lift. An adjusting block 35 is equipped with a rack 36 adapted to a spur gear 33 and a rack 37 adapted to a spur gear 34. The adjusting block 35 drives the racks 36 and 37 to slide laterally. The spur gears 33 and 34 have different diameters and different gear modules. Therefore, when rack 36 meshes with spur gear 33 and rack 37 meshes with spur gear 34, the rotational speed of the mounting shaft 32 is changed, thus enabling flexible adjustment of the rotation angle of the mounting shaft 32. This allows for precise adjustment of the rotation angle of the outrigger assembly 2, which is mounted on the mounting shaft 32 via a fixing block 31. This utility model provides a hydraulic lift that, through the use of spur gears 33 and 34 with different diameters, achieves flexible adjustment of the rotation angle of the outrigger assembly 2, thereby better adapting to rough terrain.

[0027] In one embodiment, the diameter of spur gear 33 is smaller than the diameter of spur gear 34. Spur gear 34 is positioned close to the fixing block 31. There is a gap between spur gear 33 and spur gear 34. When rack 37 meshes with spur gear 34, rack 36 is located at the gap.

[0028] The working principle and beneficial effects of the above technical solution are as follows:

[0029] The diameter of spur gear 33 is smaller than that of spur gear 34, and their gear modules are also different. As a result, the rotational speed of the mounting shaft 32 when spur gear 33 and rack 36 are meshed is faster than the rotational speed of the mounting shaft 32 when spur gear 34 and rack 37 are meshed, thereby enabling flexible adjustment of the rotation angle of the mounting shaft 32.

[0030] In one embodiment, a side mounting block 38 is also installed on the side end of the elevator body 1. The side mounting block 38 is located below the adjusting block 35. A number of limiting slots 39 are evenly distributed on the top of the side mounting block 38. A screw block 30 is fixedly installed on the adjusting block 35. A screw rod 41 is installed on the screw block 30. A limiting rod 42 that is adapted to the limiting slots 39 is installed at the bottom end of the screw rod 41.

[0031] The working principle and beneficial effects of the above technical solution are as follows:

[0032] After the outrigger assembly 2 is rotated to the appropriate position, the screw 41 on the screw block 30 is manually rotated so that the limit lever 42 is locked in the limit slot 39, thereby realizing the limit of the adjusting block 35 on the side mounting block 38.

[0033] In one embodiment, the side end of the adjusting block 35 is provided with an adjusting groove 43, and the bottom end of the adjusting groove 43 is provided with a waist-shaped hole 44. The square adjusting block 45 is slidably connected in the adjusting groove 43. The square adjusting block 45 is connected to the side end of the elevator body 1 through an adjusting rod 46. The adjusting rod 46 is slidably connected in the waist-shaped hole 44. When the adjusting block 35 moves towards the elevator body 1, the square adjusting block 45 disengages from the adjusting groove 43.

[0034] The working principle and beneficial effects of the above technical solution are as follows:

[0035] like Figure 4 As shown, this is the meshing state of spur gear 34 and rack 37, while rack 36 is located at the gap. Spur gear 33 and rack 36 are disengaged. When the adjusting block 35 is manually pulled, the square adjusting block 45 slides within the adjusting groove 43; and as... Figure 5 As shown, this is the state where spur gear 33 and rack 36 are engaged, while spur gear 34 and rack 37 are disengaged. The adjusting rod 46 is flat, thereby increasing the contact area with the oblong hole 44. When the adjusting block 35 is manually pulled, the adjusting rod 46 slides in the oblong hole 44.

[0036] In one embodiment, a set of traveling wheels 4 is installed at the bottom of the elevator body 1, and a lifting platform 6 is installed at the top of the elevator body 1 via a scissor lift 5.

[0037] The beneficial effects of the above technical solutions are:

[0038] The walking wheel set 4 is arranged to facilitate the movement of the elevator body 1.

[0039] In one embodiment, the outrigger assembly 2 comprises a hydraulic cylinder 21 mounted on the fixed block 31 and an outrigger 22 connected to the output end of the hydraulic cylinder 21.

[0040] The working principle and beneficial effects of the above technical solutions are:

[0041] The hydraulic cylinder 21 works to drive the outrigger 22 mounted on the output end of the hydraulic cylinder 21 to move towards the direction of the rugged road surface. When the outrigger 22 approaches the rugged road surface, the outrigger 22 is adjusted to the appropriate position through the meshing of the spur gear one 33 and the rack one 36, and then the precise adjustment of the position of the outrigger 22 is realized through the meshing of the spur gear two 34 and the rack two 37.

[0042] In one embodiment, the top end of the screw rod 41 is provided with a rotating block 40.

[0043] The beneficial effects of the above technical solutions are:

[0044] The rotating block 40 is arranged to facilitate the rotation of the screw rod 41 through a specific tool (open wrench, etc.).

[0045] Obviously, the above embodiments are only examples for clear illustration, and not a limitation on the embodiments. For those skilled in the art, other different forms of changes or variations can be made on the basis of the above description. It is not necessary and impossible to enumerate all the embodiments. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
