Abstract

The invention discloses a manual hoist with a weighing function. The manual hoist comprises a manual hoist body (1), further comprises an analog-to-digital converter (23) connected to the amplifying circuit, an information processing system (3) connected to the analog-to-digital converter (23), a display system (4) connected to the information processing system (3), and a storage system (5) connected to a display system (4); a static pulley (11) of the manual hoist body (1) is rotatably connected onto a housing (13) through a rotary shaft (12); and a pressure sensor (21) and an amplifying circuit connected to the pressure sensor (21) are arranged on a connection position of the rotary shaft (12) and the housing (13). With the adoption of the structure, the manual hoist can realize the functions of weighing and displaying weighed results during hoisting, and is high in practicability.

Description

technical field [0001] The invention relates to the field of hoisting equipment, in particular to a manual hoist with a weighing function. Background technique [0002] Chain block is a kind of manual lifting machine that is easy to use and easy to carry. It is suitable for short-distance lifting of small equipment and goods. The lifting capacity generally does not exceed 100T. , light weight, easy to carry, beautiful appearance, small size, and durable features. It is suitable for factories, mines, construction sites, docks, docks, warehouses, etc. to install machines and lift goods, especially for open-air and no-power operations. show its superiority. [0003] Because in many occasions, the measurement method of the goods is based on the quality of the goods, so weighing is required in most cases. In practice, the user uses a manual hoist to lift the goods on the scale for weighing. In the above-mentioned process, the user needs to operate the manual hoist all the time...
