Mounting and fixing device of tower crane weight limiter

Abstract

The invention discloses a mounting and fixing device of a tower crane weight limiter. The mounting and fixing device comprises a mounting rack, wherein a fixing plate and a fixing column are arrangedat the top of the mounting rack; fixing grooves and fixing plate fixing screws are arranged at the top of the fixing plate; a movable fixing rack is arranged at the top end of the fixing column; a pulley shaft is arranged in the movable fixing rack; a pulley is arranged on the outer side of the pulley shaft; a movable disc is arranged at one end of the pulley shaft; a gravity sensing interface isformed in the obverse side of the mounting rack; a gravity sensing transmission line is arranged at one end of the gravity sensing interface; a limiter fixing plate and a fixing column fixing buckle are arranged on one side of the mounting rack; a shockproof layer is arranged at the bottom of the mounting rack; and the mounting rack is provided with a weight limiter rear cover through the shockproof layer. By utilizing the strong movable fixing rack, the pulley, the movable disc and the fixing column, the purposes of improving the flexibility of the fixing device and facilitating mounting or dismounting of the fixing device are realized.

Description

technical field [0001] The invention relates to the technical field of installation and fixing equipment, in particular to an installation and fixing device for a weight limiter of a tower crane. Background technique [0002] The lifting capacity limiter is a safety protection device for hoisting machinery, which is specially used for electric hoist single and double girder cranes of various models and specifications. The device has the functions of sound alarm, immediate alarm, cutting off the hoisting motor circuit of the crane, and displaying the weight of the hoisted object, which can avoid equipment and personal accidents caused by overloading of the hoisting equipment. Therefore, it is of great significance to the modern safety production of industries such as metallurgy, machinery, mines, railways, docks, and warehouses. [0003] However, the installation and fixing device of the existing weight limiter is time-consuming and laborious when installing or dismounting t...
