Embodiment Construction

[0029] See attached figure 1 , 2 , 3, the scissor type hydraulic lifting platform shown in the first embodiment of the present invention, comprises work platform, the X-shaped lifting mechanism that is made up of outer arm 3, inner arm 5, hydraulic mechanism, electric control mechanism, chassis 20, so The lowermost ends of the outer arm 3 and the inner arm 5 in the lifting mechanism are mechanically connected to the two ends of the chassis 20, and a lifting cylinder 4 is arranged in the central part of the chassis, and the piston rod of the lifting cylinder drives the X-shaped shears through the fixed upper lug 7. The yoke then drives the working platform up and down. Here, the lower roller 1 and the upper roller 6 play a guiding role.

[0030] The working platform is composed of upper, middle and lower floors and worktables. Among them, the upper and middle floors are frame structures with movable plates around them. The lower frame and the upper end of the X-shaped scissor...

Abstract

The invention relates to a fork hydraulic lifting platform. An upper working table is improved on the basis of the traditional fork hydraulic lifting platform and provided with an upper layer, a middle layer and a lower layer which are provided with thrust bearings and motion guide rails; the upper layer, the middle layer and the lower layer are respectively provided with a transversely-moving oil cylinder, a longitudinally-moving oil cylinder, a rotary oil cylinder, a transverse guide rail, a longitudinal guide rail, a rotary gear and a rack motioning mechanism; with a hydraulic motor as thepower source, the transversely-moving oil cylinder and the longitudinally-moving oil cylinder directly push a platform face to make transverse movement and longitudinal movement; the rotary oil cylinder utilizes the oil cylinder to drive a rack, and the engagement of the rack with a toothed disc enables the toothed disc to rotate; and a floating platform face is driven to rotate through the rotation of the toothed disc. The fork hydraulic lifting platform realizes the transverse and longitudinal+/-50 mm movement of the floating platform face and micro adjustment of 1mm every time as well as the rotation of +/-10 degrees, has stable and reliable action, overcomes the shortcoming that the operation platform only can finish the up-down lifting in the vertical direction in the prior art, and enlarges the application range of the hydraulic lifting platform.

Description

(1) Technical field: [0001] The invention relates to a scissor-type hydraulic lifting platform, which belongs to the field of hydraulic lifting machinery and equipment. (two) background technology: [0002] In the prior art, the scissor-type hydraulic lifting platform is a multifunctional lifting and unloading mechanical device, which is widely used in logistics systems and the like. The "hydraulic lifting platform" disclosed in Chinese patent 200420079729.4 includes a working platform, a lifting mechanism, a hydraulic mechanism, an electric control mechanism, and a chassis. The lifting mechanism is composed of two sets of booms arranged in an "X" shape. The two ends of the uppermost boom are mechanically connected to the two ends of the bottom surface of the work platform, and the two ends of the lowermost boom are mechanically connected to the two ends of the chassis surface. A hydraulic mechanism is set in the central part of the chassis, the piston rod of the lifting cy...
