A convenient emergency lifter

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 an emergency lifting device that does not need to use power, fuel, can be easily carried and used, and is powerful. Background technique [0002] Lifting device, also known as "lifting device" or "crane", refers to a mechanical appliance that can lift a certain object from the ground. It is often used for handling, vehicle maintenance, rescue and disaster relief operations.
