Portable weight lifting mechanical device

Abstract

In daily life and work of people, weights are often need to be lifted from low to high (or put down from high to low), for example, loading and unloading are carried out, bricks are carried by construction workers, and the like; and most of the operations need people to lift and carry with hands and shoulders, wast time and energy and have unsafe factors at any time. In order to solve the problems, a pulley, a bracket, a cable, a rolling wheel and other accessories are combined, wherein the bracket is of a foldable (or retractable) structure, so that during hoisting work, the bracket can be conveniently unfolded, self-fixed and simply lift (or put down) the weights; and when the hoisting work is finished, a box (vehicle) of the box shape can be conveniently folded or retracted, so that carrying and moving are convenient. The device is a labor-saving machine, and can improve the work efficiency and improve the operation safety. In the specification, the specific mode of execution of thedevice is applied to the process of transferring bricks to an operating frame at a construction site, the device with the proper size is designed in a drawing, and if the device is applied, the working efficiency can be greatly improved, the labor intensity can be reduced, and the personal safety can be improved.

Description

Technical field: [0001] In our daily life and work, it is often necessary to lift heavy objects to a certain height (or slowly lower the heavy objects from a certain height) for loading and unloading or moving. At present, it is mostly done by a large number of manpower, and there is no suitable tool. The invention innovates a portable mechanical device for hoisting heavy objects, which can be applied to various lifting (or lowering) scenarios of heavy objects. Background technique: [0002] At present, the common lifting tools for heavy objects include: cranes, forklifts, electric hoists, etc. However, the application of large-scale equipment in daily life requires a large space and high cost, which is not suitable for daily use. Although the small hydraulic forklift has the lifting capacity, the lifting speed is slow and the lifting height is also limited. Therefore, in many occasions, such as heavy loading and unloading trucks that are not in fixed loading and unloading ...

However, the application of large-scale equipment in daily life requires a large space and high cost, which is not suitable for daily use

Although the small hydraulic forklift has the lifting capacity, the lifting speed is slow and the lifting height is also limited. Therefore, in many occasions, such as heavy loading and unloading trucks that are not in fixed loading and unloading places, and workers on construction sites need to manually transfer bricks to the operating frame. etc. At present, this process is all manual operation without any mechanical assistance or substitution
