Embodiment

[0037] Comply with the above technical solutions, such as Figure 1 to Figure 7 As shown, the present embodiment provides a lifting device, which includes a scissor arm lifting mechanism 1 and a vertical lifting mechanism 2 connected with the scissor arm lifting mechanism 1 .

[0038] The scissor arm lifting mechanism and the vertical lifting mechanism are jointly used for the lifting of the lifting device.

[0039] As a preference of this embodiment, the scissor arm lifting mechanism 1 includes a first upper scissor arm 3, a second upper scissor arm 4, a second lower scissor arm 5 and a first lower scissor arm 6 connected in sequence , the first upper scissors arm 3 and the first lower scissors arm 6 are hinged through the first connecting piece 7, and the second upper scissors arm 4 and the second lower scissors arm 5 are hinged through the second connecting piece 8.

[0040] The scissor arm lifting mechanism 1 also includes a scissor arm driving screw 9 connected between t...

Abstract

The invention discloses a lifting device which comprises a shear fork arm lifting mechanism and a vertical lifting mechanism connected with the shear fork arm lifting mechanism. The lifting device provided by the invention combines the shear fork type lifting device with a screw rod type lifting device, at the initial stage, lifting is performed by a vertical lifting worm device, and after liftingis performed to a certain height, the shear fork type lifting device bears subsequent lifting, so that with mechanical transmission, the lifting device is reasonable in mechanical structure, balancedin stress and low in fault rate, does not have a deflection torque and is safe and reliable.

Description

technical field [0001] The invention relates to the field of mechanical support, in particular to a lifting device. Background technique [0002] The scissor lift platform is a common lifting platform, which is used for the lifting of goods or personnel. It uses hydraulic cylinders as power, and the platform can be raised or lowered by changing the angle of the inner bracket of the scissor arm. [0003] For the scissor arm lift, the scissor arm structure is the key mechanism to realize the lifting. Whether its structural design is scientific and reasonable directly affects the working performance. In contrast, the scissor arm of the lift in the prior art has the problems of unbalanced force on the lifting device, tilting moment and instability, which causes a lot of inconvenience to the user and leads to poor user experience. Contents of the invention [0004] In view of the deficiencies and defects of the above-mentioned prior art, the purpose of the present invention is...
