Description
Technical Field
The invention relates to a cable dragging protector.
Background
Cables are generally rope-like cables made by stranding several or groups of conductors, at least two in each group, each group being insulated from each other and often twisted around a center, the entire outer surface being covered with a highly insulating covering. The device is erected in the air or installed underground or underwater for telecommunication or power transmission.
The cable is mainly composed of the following 4 parts. Firstly, a conductive wire core: made of a high conductivity material (copper or aluminum). Each core may be formed by twisting a single wire or a plurality of wires according to the requirement of laying and using conditions on the flexibility degree of the cable. Insulating layer: the insulating material used as the cable should have high insulation resistance, high breakdown field strength, low dielectric loss and low dielectric constant. Common insulating materials used in cables are oil-impregnated paper, polyvinyl chloride, polyethylene, crosslinked polyethylene, rubber, and the like. Cables are often classified as insulating materials, such as oil impregnated paper insulated cables, polyvinyl chloride cables, crosslinked polyethylene cables, and the like. Sealing the sheath: protecting the insulated wire core from mechanical, moisture, humidity, chemicals, light, etc. For moisture-sensitive insulation, a lead or aluminum extrusion seal jacket is generally used. Protecting the covering layer: to protect the sealing boot from mechanical damage. Galvanized steel strips, steel wires or copper strips, copper wires and the like are generally used as armor to wrap the armor outside a sheath (called an armored cable), and the armor layer simultaneously plays the roles of shielding an electric field and preventing external electromagnetic wave interference. In order to avoid corrosion of the steel belts and wires by the surrounding medium, they are generally coated with asphalt or wrapped with an impregnated jute layer or an extruded polyethylene or polyvinyl chloride sheath.
The cable is when laying, need pull, at the cable in-process of pulling, takes place long-time friction between cable and the ground, causes the surperficial wearing and tearing of cable easily, and later stage is oxidation with higher speed, causes the cable fault.
Based on the above problem, it is desirable to provide a cable dragging protector capable of performing sheath protection on a cable during paving.
Disclosure of Invention
The invention aims to provide a cable dragging protector which can protect the sheath of a cable during paving.
In order to solve the problems, the invention adopts the following technical scheme:
a cable dragging protector comprises a circular outer plate and a rubber plate fixedly installed on the inner side of the outer plate, wherein an open slot is formed in the outer ring of the outer plate, the radian of the open slot is 1/3-1/2 pi, the rubber plate is provided with a first open slot corresponding to the open slot, the radian of the first open slot is smaller than that of the open slot, the rubber plate is in arc transition at two ends of the first open slot, two protruding columns are arranged at the inner side positions of the rubber plate and are provided with hollowed-out grooves, so that the protruding columns are easy to deform, when the cable dragging protector is assembled with the cable, the cable enters from the first open slot and then extrudes the deformed protruding columns, the cable dragging protector enters the lower positions of the two protruding columns and contacts the inner wall of the rubber plate, and two limit stop levers are symmetrically arranged on the outer wall position of the outer plate and are positioned by taking the open slot as the center, when the outer plate deflects to enable one limiting stop lever to contact the ground, an included angle alpha is formed between the center of the open slot and the horizontal plane, and alpha is larger than 30 degrees.
Preferably, the inner wall department of outer plate is provided with a plurality of conical location inserted blocks, be connected with the member between location inserted block and the outer plate, the diameter of member is less than the maximum diameter of location inserted block, electric welding is fixed between member and the outer plate the outer wall department of rubber slab is provided with a plurality of shoulder holes, location inserted block card is gone into in the shoulder hole to by spacing in the shoulder hole, through the cooperation of location inserted block with the shoulder hole, make the rubber slab be quick detachable, be convenient for change.
