Description
Technical Field
The invention relates to a steel wire rope splitting technology, in particular to an anti-twisting device for splitting a steel wire rope or a steel strand.
Background
The steel wire rope is a key part of important equipment related to life and production safety, such as an elevator, hoisting machinery and the like. The steel wire rope is closely related to national economic development, becomes an essential component or material in the fields of energy, traffic, war industry, agriculture and forestry, ocean, metallurgy, mine, petroleum and natural gas drilling and production, mechanical chemical engineering, aerospace and the like, and has unique performance without replacement in the processes of lifting, traction, tensioning, bearing and the like. The steel strand has wide application in the fields of buildings, electric power and the like. The steel wire rope is usually in a multi-strand spiral winding structure, steel wires in each strand are also wound into strands in a spiral winding mode, the steel strand is spirally wound by a plurality of steel wires together, and the structure of the steel wire rope is the same as that of a strand of the steel wire rope; in comparison, the wire diameter of the steel wire rope is generally thin, and the wire diameter of the steel strand is thick.
After the steel wire rope or the steel strand is used for a certain service life, the steel wire usually breaks, the steel wire rope may also break strands or break ropes, and after the steel wire rope or the steel strand breaks, the whole steel wire rope or the steel strand can only be replaced and is discarded to ensure the use safety. Therefore, in the production process of industries such as long-term construction, energy, mines and the like, a large amount of waste steel wire ropes are inevitably generated, and the recycling of the waste steel wire ropes or steel strands also has important social and economic meanings. The steel wire rope, the steel strand or the raw wire are cut into small sections to form steel wire shots, and the shot cutting products can be widely applied to sand cleaning, rust removing, strengthening, forming, stress relieving, surface cleaning of various sectional materials, roughness (galling) pretreatment before coating and electroplating and the like in various fields. The steel wire rope or steel strand shot cutting firstly needs to split the steel wire rope into single strands, or split the steel strand into single steel wires, and then cut the steel wire rope into strands or split the steel wire rope into filaments and then cut the steel wire rope or the steel strand. In the process of splitting the steel wire rope or the steel strand, the steel wire rope and the steel strand are in spiral winding structures, and when the steel wire rope or the steel strand is split, the steel wire rope or the steel strand needs to be reversely twisted and drawn, so that the steel wire rope or the steel strand needs to be fixed to be smoothly split. The existing fixing mode is that one end of a steel wire rope or a steel strand is fixed through a clamping device, and free sections of the steel wire strand or the steel wire are reversely twisted, so that the longer steel wire rope or the longer steel strand is required to be integrally cut or sheared into small sections and then can be split, the efficiency is low, and the cutting or shearing needs high-power equipment, so that a large amount of power consumption is caused, and the environment-friendly concept is contrary to. For this reason, improvements are required.
Disclosure of Invention
The invention aims to provide a steel wire rope anti-twisting device aiming at the defects of low splitting efficiency and high energy consumption of the existing steel wire rope or steel strand. So as to prevent the steel wire rope or the steel strand from rotating in the braking state; and under the free rotation state, fully releasing the torsional energy reserve of the tail section steel wire rope or the steel strand which does not enter the rope threading drum. The steel wire rope or the steel strand can continuously pass through the rope penetrating cylinder in the strand separating and pulling process, and the steel wire rope or the steel strand can be rapidly separated, so that the separation efficiency is improved, the steel wire rope or the steel strand does not need to be subjected to punching shearing or cutting segmentation before separation, and the kinetic energy consumption is saved.
In order to achieve the purpose, the invention adopts the following technical scheme.
A torsion preventing device for disassembling a steel wire rope or a steel strand comprises a base and a rope threading barrel for the steel wire rope or the steel strand to pass through; the wall of a rope penetrating hole in the rope penetrating cylinder is provided with spirally distributed bulges, the rope penetrating cylinder is rotatably arranged on the base, and the rope penetrating cylinder is connected with a braking device which is used for intermittently braking the rope penetrating cylinder.
According to the invention adopting the technical scheme, the rotatable rope penetrating cylinder is arranged on the base, the rope penetrating cylinder rotates for a moment and stops at a moment under the intermittent braking action of the braking device, and the rope penetrating cylinder can effectively block the rotation of the steel wire rope or the steel strand caused by reverse twisting and strand releasing from being transmitted to the tail section which does not enter the rope penetrating cylinder under the braking state, so that the steel wire rope or the steel strand releasing device is influenced to normally release the steel wire rope or the steel strand. In the strand releasing process, the steel wire rope or the steel strand continuously passes through the rope passing cylinder, at the moment, the section to be treated which does not enter the rope passing cylinder forms torsion due to the single-stranded wire or the spiral structure of the single wire of the steel strand, and the section inevitably forms torsion energy storage under the condition that the release end of the steel wire rope or the steel strand is limited or partially limited; therefore, after the rope threading drum is converted into a freely rotatable state from a braking state, the torque of the energy reserve drives the rope threading drum to rotate quickly through the interaction of the steel wire rope strand or the steel strand monofilament and the spiral protrusion of the rope threading drum, so that the torsional energy reserve of the tail section of the steel wire rope or the steel strand is fully released. The steel wire rope or the steel strand can pass through the rope passing cylinder to move continuously in the strand separating and pulling process, and the steel wire rope or the steel strand is ensured to be rapidly separated, so that the separation efficiency is improved, the steel wire rope or the steel strand does not need to be punched or cut before separation, and the kinetic energy consumption is saved.
