vertical lifting mechanism

Abstract

The invention discloses a vertical lifting mechanism. The vertical lifting mechanism comprises a base, a loading platform and a lifting mechanism which is arranged between the base and the loading platform and used for driving the loading platform to vertically lift; the lifting mechanism comprises a fixing part, at least a mobile part and a screw rod which are sequentially arranged; the lower end portion of the fixing part is fixed on the base; the lower end surface of every mobile part is provided with a chain wheel; chains are engaged to the chain wheel; the screw rod is arranged on the loading platform along the vertical direction; the screw rod can idle along the peripheral direction relative to the loading platform; a nut is engaged outside the screw rod through threads; the nut is fixedly connected with the mobile part which is far from the fixing part and arranged on the innermost side; the upper end portion of the screw rod is provided with a hand wheel which is used for driving the screw rod to rotate. The vertical lifting mechanism is a pure mechanical mechanism, simple in structure and low in manufacturing cost; avoids a hydraulic system, does not contain hydraulic oil, completely does not need driving of exterior energy, is energy-saving and environmental friendly and can be applicable to some working environments having rigorous requirements for cleaning.

Description

technical field [0001] The invention relates to the technical field of transport vehicles, in particular to a vertical lifting mechanism. Background technique [0002] Due to the characteristics of small size, light weight, small turning radius and large carrying capacity, the vertical column lift truck is especially suitable for high-altitude operations in narrow spaces such as warehouses and aisles. It has been widely used in stations, docks, bridges, Halls, workshops and other indoor and outdoor mechanical installation, equipment maintenance, building maintenance and cargo storage, etc. However, the lifting mechanism of the vertical column lift truck manufactured by the current manufacturer is generally driven by a hydraulic system or an electric system. Due to the high cost of use and maintenance of the hydraulic system and the leakage of oil, the vertical column lift truck cannot be used for food Some relatively harsh clean working environments such as processing, and ...

However, the lifting mechanism of the vertical column lift truck manufactured by the current manufacturer is generally driven by a hydraulic system or an electric system. Due to the high cost of use and maintenance of the hydraulic system and the leakage of oil, the vertical column lift truck cannot be used for food Some harsh clean working environments such as processing, and because the push rod mechanism of the electric system is relatively expensive, the cost of the whole vehicle is high
