Small portable type symmetrical crane

Abstract

The invention discloses a small portable type symmetrical crane. The small portable type symmetrical crane comprises a vehicle frame, a travelling driving mechanism and lifting driving mechanisms, wherein the travelling driving mechanism is arranged at the bottom of the vehicle frame and used for driving the vehicle frame to conduct horizontal moving at any direction, and the lifting driving mechanisms are symmetrically arranged on the two sides of the vehicle frame and used for hauling heavy objects; each lifting driving mechanism comprises a winding engine used for providing hauling power, ahauling sliding block used for driving the heavy objects to go up and go down, a hauling cable used for transmitting output power of each winding engine to the corresponding hauling sliding block anda hauling guide rail used for providing a moving rail for each hauling sliding block; and each hauling sliding block is outwards provided with a load bearing rod used for lifting and taking the heavyobjects, the two ends of the hauling cables are correspondingly connected to the hauling sliding blocks and rotating shafts of the winding engines, and the hauling cables are arranged along the hauling guide rails. According to the small portable type symmetrical crane, the structure is simple, mounting is convenient, the occupied position is small, the requirement for working conditions is low,the cost is low, and the small portable type symmetrical crane can fully meet safety technical requirements and daily use requirements required by light-weight lifting.

Description

technical field [0001] The invention relates to the field of mechanical transportation, in particular to a small portable symmetrical crane. Background technique [0002] At present, most lifting machinery is used in engineering construction and other fields. Commonly used crane mechanisms include screw lifting mechanism, hydraulic lifting mechanism, electric push rod lifting mechanism and other lifting mechanisms that can achieve lifting functions, but hydraulic lifting mechanisms are mostly used in high-altitude and heavy-load workplaces. The screw lifting mechanism has low lifting speed, complex structure, high maintenance cost and easy wear and tear. At present, the crane has not been miniaturized and is not easy to carry. SUMMARY OF THE INVENTION [0003] In order to solve the above problems, the purpose of the present invention is to provide a small portable symmetrical crane, which not only has a simple structure, is easy to install, occupies a small position, but ...

AI Technical Summary

Problems solved by technology

Commonly used crane mechanisms include screw lifting and lifting mechanisms, hydraulic lifting mechanisms, electric push rod lifting mechanisms and other lifting mechanisms that can realize lifting functions, but hydraulic lifting mechanisms are mostly used in high-altitude and heavy-duty workplaces. The lifting speed of the screw lifting lifting mechanism is low, the structure is complex, the maintenance cost is high, and it is easy to wear and tear. Moreover, the crane has not yet been miniaturized and is not easy to carry
