Problems solved by technology

Since the pitch angle of the boom changes greatly during work and maintenance, the above anti-off-rope device cannot effectively protect the wire rope at any angle
Since the above anti-off-rope devices are all fixed, it is easy to cause the wire rope to be stuck, resulting in a broken rope accident

Abstract

The invention discloses a device for preventing a pulley rope from slipping off. The device is characterized by comprising bearings, counter weights, support plates and positioning gear rods, the bearings are arranged at the two ends of a revolving shaft of a pulley of a crane in a sleeving mode, each counter weight is constituted by a swing arm and a balancing weight, each swing arm is vertically arranged, the upper end of each swing arm is fixed to the lower end of the corresponding bearing, each balancing weight is fixed to the lower end of the corresponding swing arm, one end of each support plate is fixed to the side face of the corresponding bearing, the positioning gear rods are arranged to be parallel to the revolving shaft of the pulley of the crane, the two ends of each positioning gear rod are fixed to the other ends of the support plates located at the two sides respectively, and each support plate and the corresponding swing arm are arranged in a forked mode, wherein an obtuse angle is formed between each support plate and the corresponding swing arm. A swing structure is adopted for the device, so that under emergency, the steel wire rope cannot squeeze and be stuck with the pulley, rope fracture accidents are avoided, and the service life of the device can be long.

Description

technical field [0001] The invention relates to an anti-off-rope device, in particular to an anti-off-rope pulley device. Background technique [0002] A crane refers to a multi-action hoisting machine that lifts vertically and carries heavy objects horizontally within a certain range. Also known as a crane. At present, Guangdong Shunfa Heavy Equipment Co., Ltd. has gradually canceled the function of hoisting and traveling for major hoisting machines in China. Some working characteristics of lifting equipment are intermittent movements, that is, in a working cycle, the corresponding mechanisms for retrieving, moving, unloading and other actions work alternately. The development and use of cranes in the market are becoming more and more extensive. [0003] In various types of single-jib cranes with pitch and amplitude, the anti-off-rope device of the fixed pulley at the head of the jib generally has the following forms: 1. Use the distance control between the steel structur...
