Municipal engineering cable equipment

Abstract

The invention belongs to the field of cable laying, and particularly relates to municipal engineering cable equipment which comprises rods A, telescopic rod structures, supporting feet, guide rings, idler wheels A, idler wheels B and the like. Four supporting feet matching the wall of a cable well are symmetrically installed on the two rods A connected through the two symmetrically-distributed telescopic rod structures. According to the invention, when the wire drawing direction is changed and is not consistent with the running direction of the underground cable of the cable, by adjusting thedirections of the idler wheels A and the idler wheels B, the cable is still located on the idler wheels A and the idler wheels under the condition that the pulling direction of cable pulling personnelon the ground is changed; therefore, abrasion caused by contact between the cable and the well edge or the corner in the cable well due to the fact that the cable is separated from the idler wheels Aand the idler wheels B when the pulling direction of the ground wire pulling personnel is changed is avoided; and the cable is prevented from being damaged while the cable construction efficiency isguaranteed.

Problems solved by technology

[0002] In the traditional cable laying method, the cable in the cable well is pulled without any auxiliary equipment. During the pulling process, the cable rubs against the edge of the cable well or the corner in the cable well, causing The skin of the cable is worn or damaged to varying degrees during the pulling process

The service life of cables with worn skin is limited, and the safety of cables with damaged skin cannot be guaranteed during actual operation, which affects the quality of cable construction

On the other hand, the friction between the cable and the well edge slows down the speed of cable laying, thus reducing the efficiency of cable laying to a certain extent

[0003] The azimuths of the rollers A and B in the "A special bracket for interspersed cables in municipal engineering" with the published publication number "103956692A" are fixed, so that it is only suitable for the situation where the direction of the pull wire is consistent with the running direction of the cable underground

If the actual situation on the road surface causes the direction of the cable on the ground to change, at this time, the cable will break away from the roller A and roller B in the "a special bracket for interspersed cables in municipal engineering" with the publication number "103956692A" under the action of tension, so that the cable can be reassembled. Contact with the edge of the well or the corner of the cable well to generate friction and cause the cable skin to be worn or damaged

The "a special bracket for interspersed cables in municipal engineering" with the publication number "103956692A" cannot completely solve the problem of friction between the cable and the well edge in the traditional pulling method without the aid of auxiliary equipment
