Embodiment Construction

[0011] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0012] Such as Figure 1-2 As shown, a pneumatic lifting device of the present invention includes a lifting platform 2, three airbag cylinders 1, a guide rod 3, a wear-resistant copper sleeve 4, a copper sleeve fixing seat 5, a lifting protection device 6, a pin Shaft 7, guide rod limit block 8 and fixed frame 9;

[0013] The lifting platform 2 is the main force-bearing part, which is in direct contact with the load. The upper surface of the airbag cylinder 1 is fixedly connected to the lower surface of the lifting platform 2, and the lower surface is fixedly connected to the upper part of the fixed frame 9; the wear-resistant copper sleeve 4 is fixed on the upper part of the fixed frame 9 through the copper sleeve fi...

Abstract

The invention discloses a pneumatic lifting device. The pneumatic lifting device comprises a lifting platform, air bag type air cylinders, guiding rods, wear-resistant copper sleeves, lifting protection devices, pin shafts, limiting blocks for the guiding rods and a fixing frame, wherein the upper surface of the lifting platform is directly in contact with a carried weight; the upper surfaces of the air bag type air cylinders are fixedly connected with the lower bottom surface of the lifting platform; the lower surfaces of the air bag type air cylinders are fixedly connected with the upper part of the fixing frame; the wear-resistant copper sleeves are fixed at the upper part of the fixing frame; after penetrating through the wear-resistant copper sleeves, the top ends of the guiding rods are fixedly connected with a fixing sleeve on the lower bottom surface of the lifting platform; the limiting blocks for the guiding rods are fixed at the bottoms of the corresponding guiding rods separately; when a main air channel supplies air to the air bag type air cylinders (1), the air bag type air cylinders are inflated and expand, so that the lifting platform and the guiding rods are pushed to move together upwards along the inner sides of the wear-resisting copper sleeves (4). According to the pneumatic lifting device disclosed by the invention, the air bag type air cylinders which are high in capability of bearing axial loads and radial loads are adopted so that the flexible transmission of bearing force, effective stroke adjustment and high-efficiency control over the vibration can be realized, and the safety of the whole lifting and transporting process is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of pneumatic lifting, and in particular relates to a pneumatic lifting device for safe lifting and transportation. Background technique [0002] Generally, the commonly used methods of lifting are: lifting by hydraulically driven scissor mechanism, direct lifting by electric cylinder, etc. In the case of a large lifting force, hydraulically driven scissors are generally used to lift, but this method requires hydraulic pumps and other components, which is prone to oil leakage and unclean work sites; and direct lifting by electric cylinders not only costs more High, and the lift is not strong enough. Contents of the invention [0003] The purpose of the present invention is to provide a pneumatic lifting device to solve the problems of insufficient lifting force and oil leakage due to hydraulic drive. [0004] The technical solution of the present invention is: a pneumatic lifting device, including a lifti...
