Convenient rescue jack

Abstract

The invention relates to a hoisting device and particularly relates to a convenient rescue jack which is convenient to carry and use and strong in power and can be implemented without using a power supply and fuel. The convenient rescue jack comprises thirty-six components such as a wedge plate end cover, a wedge plate, a handwheel bearing end cover, a base shell, a guide post elastic block, a guide post screw hole end cover, a handwheel handle, a handwheel, a handwheel bearing, a handwheel shaft pin, a tapered gear, a reversing disc, a top pillar, a top pillar top pedestal, a top pedestal fixed screw, a top pillar sliding bearing, a guide post, a guide post handle, a guide post end cover, a hoisting plate, and the like; and the thirty-six components are formed into three modules, namely a base module, a power module and a hoisting module. By using the convenient rescue jack provided by the invention, the defects that the existing known hoisting device is huge in equipment, poor in adaptability, small in strength and the like are overcome, and the convenient rescue jack provided by the invention has the characteristics of small and exquisite structure, powerful function, strong adaptability, wide application range, and the like; and in addition, the technical scheme is simple to implement and the convenient rescue jack is easy to manufacture; and the prepared jack product is beautiful in structure, solid, durable, convenient to use, broad in market space and high in added economic value.

Description

technical field [0001] The invention relates to a lifting device, in particular to a powerful emergency lifter which can be easily carried and used without using a power supply or fuel. Background technique [0002] A jack, also known as "lifting device" or "crane", refers to a mechanical device that can lift a certain object from the ground. It is often used in operations such as handling, vehicle maintenance, and emergency rescue. [0003] Known emergency lifter at present, has two big classes, and a class is manpower lifting device, as iron brazing, steel pick, jack etc., and another kind is mechanical lifting device, as forklift, winch, hoist etc. . Among them, the human lifting device is easy to carry, easy to operate, can adapt to complex terrain and features, and can work under special conditions without power resources and fuel resources. The disadvantage is that the lifting force is small and the efficiency is low. Large and heavy objects seem powerless; the mecha...
