Abstract

The invention relates to an overload device of a crane, in particular to a protection device for safely using the crane, belonging to the technical field of measurement control. The invention is characterized in that a bearing is mounted in a pulley; a shaft and a shaft sleeve are installed in a pulley support; a pallet shaft is used to fix the shaft on the pulley support by using a bolt; a shafttype sensor is fixed in the pulley support; the pallet shaft is used to fix the shaft type sensor on the pulley support by using the bolt; a lantern ring, a rope clip, a steel wire rope, a shackle and an ear plate are connected to be a whole; and the ear plate is fixed at a position requiring force measurement of the crane by using electrical wielding. The invention has the advantages that the structure is simple, compact and reliable; weighting and force measurement have high precision and good stability, and mechanical parts are greatly simplified, thereby reducing production cost and simplifying work amount of installation and debugging; the work is safe and reliable; and the device is convenient for assembling and dismantling, and can improve correct rate of count to ensure the safe use of the crane.

Description

Technical field [0001] The invention relates to an overload device of a crane, in particular to a protection device for the safe use of a crane, and belongs to the technical field of metering control. Background technique [0002] At present, various overload devices used in the production and use of cranes have many problems, such as complex structures, difficult installation and disassembly, and low counting accuracy, which virtually bury the cranes hidden dangers in production safety. Summary of the invention [0003] The purpose of the present invention is to overcome the above shortcomings, thereby providing a crane overload device that is safe and reliable in work, easy to assemble and disassemble, can improve the counting accuracy, and ensure the safe use of the crane. [0004] According to the technical solution provided by the present invention, the overload device of the crane includes a pulley, a shaft, a shaft sleeve, a chuck shaft, a pulley support, a bush, a chuck plat...
