Description

Technical Field

[0001] The utility model relates to the technical field of industrial lifts, in particular to a hydraulic lift with a rotary support. Background Art

[0002] A hydraulic lift is a type of lifting equipment driven by a hydraulic system and is widely used in various fields, including industrial production, construction, logistics and transportation, and public services. It primarily achieves its lifting function through the pressure transmission of hydraulic oil. The hydraulic oil is pressurized by a vane pump and enters the oil cylinder through a series of control valves and pipelines, pushing the cylinder piston to move, thereby driving the platform up and down. During descent, the vane pump stops, the control valve opens the oil drain circuit, and the platform slowly descends under its own weight.

[0003] However, in actual production applications, due to the different production processes in different fields, the height settings of hydraulic lifts are different, ranging from a few meters to dozens of meters. When transporting or carrying objects, the platform is only raised and supported by the cylinder. However, poor cylinder material or unreasonable sealing structure design may cause the cylinder to leak during use, thereby affecting the support effect; or during long-term use, the internal parts of the cylinder may wear or fatigue due to friction and vibration, which will also reduce the supporting force of the cylinder and may also cause safety accidents. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a hydraulic lift with a rotary support to solve one or more problems in the prior art.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows:

[0006] A hydraulic lift with a rotating support includes a base and an oil cylinder, wherein the oil cylinder is arranged on the base. The lift also includes a scissors-type mechanism and a platform, wherein the platform is matched with the oil cylinder and is also connected to the scissors-type mechanism. The lift also includes a rotating support assembly, wherein a part of the rotating support assembly is arranged on the base. When the platform rises, the rotating support assembly cooperates with the platform for support.

[0007] Furthermore, the rotation support assembly includes a first support member, a second support member and a support shaft, the first support member is arranged on the base, and the second support member is rotatably matched with the first support member via the support shaft.

[0008] Furthermore, the rotation support assembly includes a connecting rod and a connecting plate, one end of the connecting rod is connected to the second support member, and the other end is connected to the connecting plate.

[0010] Furthermore, the platform is provided with a docking portion, and one end of the second support member can be fixedly or detachably engaged with the docking portion.

[0011] Furthermore, the first support member, the second support member and the support shaft are all symmetrically arranged about the center of the connecting plate.

[0012] Furthermore, the scissor-type mechanism includes at least two groups of first lever arms and second lever arms, and the first lever arms and the second lever arms are rotatably connected to each other.

In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, please refer to the accompanying drawings.

[0023] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings in this specification are only used to match the contents disclosed in the specification so that people familiar with this technology can understand and read them. They are not used to limit the conditions for the implementation of this utility model and therefore have no substantive technical significance. Any structural modifications, changes in proportional relationships, or adjustments in size should still fall within the scope of the technical contents disclosed in this utility model without affecting the effects and purposes that can be achieved by this utility model.

[0024] The following describes the specific structure of a hydraulic lift with a rotating support:

[0025] See also Figures 1 to 3 The hydraulic lift with rotating support in this embodiment includes a base 1 and a cylinder 2. The cylinder 2 is arranged on the base 1. The lift also includes a platform 4, which is coordinated with the cylinder 2. Preferably, in this embodiment, four cylinders 2 are arranged on the base 1 for lifting the platform 4.

[0026] Furthermore, the elevator also includes a scissors-type mechanism 3, and the platform 4 is also connected to the scissors-type mechanism 3. The scissors-type mechanism 3 includes at least two groups of first lever arms 301 and second lever arms 302. The first lever arms 301 and the second lever arms 302 are rotatably connected to each other. Preferably, two groups of the first lever arms 301 and the second lever arms 302 are provided in this embodiment.

[0027] Furthermore, one end of the first lever arm 301 is rotatably connected to the base 1, and the other end of the first lever arm 301 is rotatably connected to the platform 4. One end of the second lever arm 302 is rotatably connected to the base 1, and the other end of the second lever arm 302 is rotatably connected to the platform 4. As the oil cylinder 2 pushes the platform 4 upward, the first lever arm 301 and the second lever arm 302 rotate around the base 1 and the platform 4 as the platform 4 rises, thereby opening.

[0028] Furthermore, the scissor mechanism 3 also includes a buffer 303. A first connecting shaft 304 is provided between the first lever arms 301, and a second connecting shaft 305 is provided between the second lever arms 302. One end of the buffer 303 is rotatably connected to the first connecting shaft 304, and the other end of the buffer 303 is rotatably connected to the second connecting shaft 305. The buffer 303 can provide a buffering effect when the platform 4 rises or falls, thereby preventing damage to the first lever arm 301 and the second lever arm 302 due to the platform 4 rising or falling too quickly.

[0029] Furthermore, the elevator further includes a rotating support assembly 5 , a portion of which is disposed on the base 1 . When the platform 4 rises, the rotating support assembly 5 cooperates with the platform 4 for support.

[0030] Furthermore, the rotating support assembly 5 includes a first support member 501 , a second support member 502 and a support shaft 503 . The first support member 501 is disposed on the base 1 , and the second support member 502 is rotatably engaged with the first support member 501 via the support shaft 503 .

[0031] Furthermore, the rotating support assembly 5 includes a connecting rod 504 and a connecting plate 505 . One end of the connecting rod 504 is connected to the second support member 502 , and the other end of the connecting rod 504 is connected to the connecting plate 505 .

[0032] Furthermore, the rotating support assembly 5 further includes a motor 506, which is disposed on the base 1, and the connecting plate 505 is rotatably connected to the motor 506. Driven by the motor 506, the connecting plate 505 rotates, thereby driving the connecting rod 504 to rotate, and the connecting rod 504 then pulls the second support member 502 to rotate relative to the first support member 501.

[0033] Furthermore, the platform 4 is provided with a docking portion 401 , and one end of the second support member 502 can be fixedly or detachably engaged with the docking portion 401 .

[0034] Furthermore, the rotating support assembly 5 is respectively provided with two first support members 501, two second support members 502 and two support shafts 503, and all are symmetrically arranged about the center of the connecting plate 505, so that the two second support members 502 can be rotated and adjusted synchronously under the drive of the motor 506.

[0035] The specific working process of the hydraulic lift with rotating support described in the embodiment of the utility model is described below:

[0036] The oil cylinder 2 pushes the platform 4 up to a height exceeding the maximum height to which the second support member 502 can rotate. Then, the motor 506 drives the connecting plate 505 to rotate, thereby driving the connecting rod 504 to rotate. Then, the connecting rod 504 pulls the second support member 502 to rotate relative to the first support member 501. Under the joint action of the scissor mechanism 3 and the oil cylinder 2, the height of the platform 4 is slowly lowered so that the docking portion 401 and the second support member 502 are connected, thereby forming a supporting effect. After the docking portion 401 and the second support member 502 are connected, even if the height of the platform 4 is lowered, the second support member 502 can be rotated around the first support member 501 under the drive of the motor 506 to adapt to the current height of the platform 4.

[0037] When the work is completed, the connection between the docking portion 401 and the second support member 502 is released, and the motor 506 is driven in reverse to disengage the second support member 502 from the docking portion 401 and reset. Then, under the joint action of the scissor mechanism 3 and the cylinder 2, the height of the platform 4 is slowly lowered back to an unused state.

[0038] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
