Omni-directional precise transfer crane

Abstract

The invention discloses an omni-directional precise transfer crane, and relates to the technical field of hoisting machinery equipment. The omni-directional precise transfer crane comprises a machinebody, wherein the machine body comprises a frame, a lifting mechanism and a travelling mechanism, and a sliding mechanism is arranged on the frame; the sliding mechanism comprises a guide rail, a sliding block is arranged on the guide rail in a sliding mode, a transmission screw is arranged on the guide rail, penetrates through the sliding block and is in threaded connection with the sliding block, and a first driving device is arranged at one end of the guide rail; the lifting mechanism comprises a winding drum, an upper pulley block, a lower pulley block, ropes, a lifting appliance platformand a lifting appliance; the upper pulley block is arranged on the sliding block, the lower pulley block is arranged on the lifting appliance platform, upper pulleys are connected with the lower pulley block through the ropes in a winding mode, the winding drum is rotationally arranged on the sliding block, and a second driving device is arranged on the sliding block; and the travelling mechanismcomprises steering wheels. The omni-directional precise transfer crane is simple and reliable in structure, good in safety, small in space occupation, flexible in movement, capable of preventing swingand high in precision.

Description

technical field [0001] The invention relates to the technical field of hoisting machinery and equipment, in particular, it relates to an omnidirectional precision transfer crane. Background technique [0002] A crane refers to a multi-action hoisting machine that lifts vertically and carries heavy objects horizontally within a certain range. The working characteristics of lifting equipment are intermittent movements, that is, the corresponding mechanisms for taking materials, moving, and unloading in a working cycle are alternately working. The development and use of cranes in the market are becoming more and more extensive. [0003] Nowadays, in manufacturing factories, docks and other environments, a large number of goods need to be transported horizontally. Straddle carriers and traditional cranes can meet the needs of lifting and transporting large-scale goods. However, because most of the existing cranes use the traditional single-rope winding method, the way the troll...

AI Technical Summary

Problems solved by technology

The fixed-point hoisting of traditional lifting equipment has a large size and takes up a lot of space, which cannot meet the requirements of flexible handling indoors, and the single-rope winding method is easy to shake and has poor stability, resulting in low accuracy of lifting goods, which needs to be improved. place
