Two-degree-of-freedom portable jack

Abstract

The invention discloses a two-degree-of-freedom portable jack, and belongs to the field of mechanical equipment. The jack comprises a base assembly, a translation assembly and a lifting assembly, wherein the base assembly comprises load bearing wheels, steering wheels, a base supporting frame and a vertical base mounting plate; due to arrangement of the base assembly, free movement of the jack onthe ground can be realized; the translation assembly comprises a hand wheel, a sprocket, a chain, a linear guide rail pair, a supporting plate and a lead screw pair, and due to arrangement of the translation assembly, horizontal translation of the jack can be realized; and the lifting assembly comprises a support column, a support arm, a jack, a telescopic arm and a lifting hook, and can be used for lifting up and move heavy objects. The two-degree-of-freedom portable jack disclosed by the invention has degrees of freedoms which are located in the directions of up-down movement and horizontaltranslation, and has the advantages of being simple in structure and flexible in use.

Description

technical field [0001] The invention belongs to the field of mechanical equipment, in particular to a two-degree-of-freedom portable jack. Background technique [0002] A crane is a kind of mechanical equipment that can lift heavy objects and has the function of short-distance transportation. At present, the lifting equipment for small space, small lifting capacity and special working scenes is relatively scarce in the market. For small space, small loading and unloading weight The goods are mainly carried out by manpower, which is time-consuming and labor-intensive. [0003] For special lifting scenarios such as field, emergency, station, warehouse, delivery, etc., the manual method is inefficient; in the above scenarios, a portable lifter that can play a good role is urgently needed. For example: communication equipment, testing instruments, generators (300-500kg) in emergency work, etc. need to be transported by portable cranes to save time and manpower, and gain valuabl...
