Embodiment Construction

[0026] Below in conjunction with the accompanying drawings, the technical scheme and optimal mode adopted by the patented screw jack will be further described:

[0027] Its static structure see figure 1 : As shown in the figure, the patented screw jack is composed of a motor (7-1), a limiter, a chassis (2), a lifting cylinder, a support rod (8) and a guardrail (3), wherein: the motor (7- 1) Installed under the bottom frame (2), the limiter is installed in the top tube (6) and the bottom tube (4) (5), the support rod (8) is installed in the top tube (6) and the bottom frame (2) Between, guardrail (3) is installed on top cylinder (6).

[0028] The four legs of its underframe (2) adopt the female leg (2-2) sleeve leg (2-3) method, the purpose is: the support rod (8) is loosely connected to the sub-leg (2-3), and the support rod (8) The upper end is fixed on the top cylinder (6). When the height of the lifting cylinder changes, the angle between the support rod (8) and the lifti...

Abstract

A spiral elevator comprises a three-phase alternating-current motor, a bottom frame, a lifting cylinder, a supporting rod, a stopper and a guardrail. The spiral elevator is characterized in that the three-phase alternating-current motor serves as power to drive the lifting cylinder of the elevator to rotate and rise, the bottom frame and the supporting rod of the elevator serve as an assisting unit. The stopper serves as a protection unit of the three-phase alternating-current motor, and the guardrail is mounted on a top cylinder of the elevator to take off and land vertically, accordingly, a movable elevation platform which is support-free, dependency-free and capable of rising straight from the ground to transport goods to the air is achieved. Compared with an electromechanical hydraulic elevation platform, the elevator is simple, in no need of maintenance cost, high in safety, reasonable in structure, scientific in design, wide in use, low in developing starting cost and broad in business outlook.

Description

technical field [0001] The invention relates to the mechanical and electrical field, in particular to a screw jack technology. Background technique [0002] The lifting platform is a multi-functional lifting and loading mechanical equipment, which can be used in factories, automatic warehouses, parking lots, municipal administration, docks, construction, decoration, logistics, electricity, transportation, petroleum, chemical industry, hotels, gymnasiums, industrial and mining, enterprises and other high-altitude There are many types of operation and maintenance at present, including mobile, fixed, guide rail, aluminum alloy, folding arm, curved arm, and vehicle-mounted. The structure is basically a combination of electromechanical and hydraulic pressure. The advantages of this type of product are stability and high safety, but the disadvantages are that the structure is relatively complicated, delicate and expensive, and the maintenance cost is high. The present invention i...
