Background

The steel wire rope can be seen everywhere in engineering construction, and the steel wire rope is small enough for installing a scaffold and big enough for bearing key engineering. The steel wire rope commonly adopted in China is a mode that a plurality of carbon steel wires with the diameter of 0.3-3 mm are twisted into strands, and then a plurality of strands are twisted into a rope around a rope core. In the construction and use process, the steel wire rope and the steel member are connected through a clamping or pressing sleeve method, the steel wire rope belongs to a temporary bearing structure, the steel wire rope cannot be movably disassembled before the construction is not finished, the steel wire rope must be ensured to be intact, and knotting and abrasion are avoided. Under the great condition of steel member self quality, the contact site of wire rope and steel member edges and corners can take place concentric or eccentric wearing and tearing under the pulling force effect, because the complexity of work progress, the continuous accumulation of wire rope wearing and tearing not only can lead to wire rope to take place disconnected silk phenomenon, also can produce unrecoverable's destruction to the steel member. The currently adopted method is: and directly connecting a cushion at the contact part of the steel wire rope and the edge of the steel member. However, after the steel wire rope is stressed and tensioned, the rubber pad may fall off and be damaged, so that the steel wire rope is in direct contact with the steel member.

SUMMERY OF THE UTILITY MODEL

The utility model discloses an alleviate steel member edges and corners to wire rope's wearing and tearing, restrict the wire rope displacement simultaneously. The steel wire rope protection device for the edges and corners of the steel member comprises a protective cylinder, wherein the contact surface of the protective cylinder and the steel wire rope is an edge-free smooth surface, and the edge of the protective cylinder, which is abutted against the steel member, is vertical; the protective cylinder is provided with a plurality of internal thread pipes penetrating through the protective cylinder body, the internal thread pipes are arranged in two rows, and the internal thread pipes are in threaded connection with bolts; and magnets are arranged at the tail of the drooping edges at the two sides of the casing.

Furthermore, a rubber cushion layer is arranged on the protective sleeve and covers the contact surface of the protective sleeve and the steel wire rope.

Furthermore, mushroom nails are distributed on the outer side face of the protective cylinder, and the rubber cushion layer is buckled with the mushroom nails. The rubber cushion layer is attached to the protective cylinder through the mushroom nails fixedly arranged on the outer side face of the protective cylinder, so that the rubber cushion layer is firm to mount and is difficult to fall off after long-term use and weather erosion. The rubber cushion layer is convenient to damage and replace, and can be pulled out by external force and installed again.

Furthermore, the contact surface of the protective cylinder and the steel wire rope is a hyperbolic paraboloid, the steel wire rope naturally rolls towards the center of the protective cylinder and is not easy to fall off, and the protective cylinder can simultaneously bear a plurality of steel wire ropes, so that the use is more flexible and the construction cost is reduced.

Furthermore, the end that the bolt precessed is hemispheroid, and spherical end and steel member contact, and bolt end atress is more even, reduces the extrusion of bolt to the steel member surface simultaneously.

Furthermore, the protective cylinder is provided with four internal thread pipes in total, and the four internal thread pipes are symmetrically arranged relative to the central line of the section of the protective cylinder body.

Further, the extension line of the axis of the bolt passes through the circle center of the edge of the outer side of the section of the casing body where the bolt is located, so that the stress on the edge of the bolt and the edge of the casing is more balanced, the casing is installed on edges and corners of steel members at different angles under the same pressure, and the root of the internal thread pipe connected with the casing is not prone to stress concentration and fracture.

Compared with the prior art, the utility model has the advantages that:

the utility model provides a pair of steel member is wire rope protection device for edges and corners, simple manufacture, convenient to use, through a saddle-shaped protects a section of thick bamboo support wire rope, the wire rope is difficult for controlling rocking, takes place the displacement. Meanwhile, the rubber cushion layer is connected with the mushroom nails on the outer surface of the pile casing, the rubber cushion is prevented from falling, friction between the steel wire rope and the edges and corners of the steel member is effectively controlled, and abrasion and damage of the steel wire rope are prevented. Simultaneously, accessible adjusting bolt, the control bolt is twisted into the inboard length of a protecting section of thick bamboo soon to at the edges and corners that agree with the steel member, can install in the steel member edges and corners department of multiple angle seamlessly.

Detailed Description

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.

As shown in fig. 1; a steel wire rope protection device for edges and corners of a steel member comprises a pile casing 1, wherein the contact surface of the pile casing 1 and a steel wire rope is an edge-free smooth surface, and the edge of the pile casing 1 abutted to the steel member is vertical; protect and be provided with 4 internal thread pipes 2 that run through its body on the section of thick bamboo 1, 4 internal thread pipes 2 arrange for two, 4 internal thread pipe 2 for protect the central line symmetry setting in 1 body cross-section of a section of thick bamboo, 4 internal thread pipes 2 set up for protecting 1 body length direction's central line symmetry simultaneously. The internal threaded pipe 2 is in threaded connection with a bolt 3; the screwed end of the bolt 3 is in a semi-sphere shape. The extension line of the axis of the bolt 3 passes through the circle center of the outer side edge of the section of the body of the pile casing 1 where the bolt is located. Bolt 3 and steel member butt 1, the auxiliary stay protects a section of thick bamboo 1, places and protects 1 middle part stress concentration of a section of thick bamboo, and the too big fracture that leads to of load.
