Tapered protecting sleeve connected with scattered rope sling to prevent main cable from rustiness

Abstract

The invention relates to a tapered protecting sleeve connected with a scattered rope sling to prevent a main cable from rustiness. The tapered protecting sleeve comprises an upper half tapered protecting steel plate and a lower half tapered protecting steel plate which can be spliced and fixed into a taper, wherein a drainage hole is formed at the bottom of the lower half tapered protecting steel plate; the tip of the taper formed by the upper half tapered protecting steel plate and the lower half tapered protecting steel plate is connected with the scattered rope sling; a steel plate matched with a port is arranged at an opening at the other end of the taper; and a plurality of branch cable open holes are formed in the steel plate. The upper half tapered protecting steel plate and the lower half tapered protecting steel plate which can be spliced and fixed into the taper are adopted, the tip of the taper is connected with the scattered rope sling, and the drainage hole is formed at the bottom of the lower half tapered protecting steel plate, so that the rustiness of a main cable and branch cables due to water accumulation in the scattered rope sling can be avoided. Since the steel plate is fixed at one end of the taper, and the branch cable open holes are formed in the steel plate, the ingress of the branch cables can be facilitated.

Description

technical field [0001] The invention belongs to the field of cable rust prevention, and in particular relates to a conical protective cover for preventing main cable from rusting by connecting loose cable sleeves. Background technique [0002] Due to the needs of anchoring, the main cable needs to be spread out when approaching the main tower. However, at present, only scatter cables are used to disperse the strands in China, resulting in a large force on the scatter cables; there is only a short section from the scatter cable to the anchorage end of the scatter cables to prevent rain The scatter cable is easy to be corroded due to the cover, and the scatter cable at the upstream port of the scatter cable sleeve is densely packed, which is easy to accumulate rainwater and cause corrosion of the scatter cable and the main cable. [0003] At present, there are the following problems in the domestic market where only the scatter cable is used to disperse the main cable: (1) The...

Problems solved by technology

[0002] Due to the needs of anchoring, the main cable needs to be spread out when approaching the main tower. However, at present, only scatter cables are used to disperse the strands in China, resulting in a large force on the scatter cables; there is only a short section from the scatter cable to the anchorage end of the scatter cables to prevent rain The scatter cable is easy to be corroded; the upstream port of the scatter cable sleeve is densely packed, and it is easy to accumulate rainwater to cause corrosion of the scatter cable and the main cable. At present, there is no special protection equipment for this section of the cable in China.

[0003] At present, there are the following problems in the domestic market where only the scatter cable is used to disperse the main cable: (1) There is only a small section of rain cover from the scatter cable to the anchor end, which makes this section of the scatter cable exposed to the air and is easy to rust; (2) The scatter cable The upstream cross-section of the sheath is too small and the loose cables are dense, which will easily accumulate water and cause corrosion on the loose rope sheath and the main cable.

[0004] Due to the above problems, the sub-cables are easy to rust, and the upstream port of the loose cable is easy to accumulate water. The corrosive gas can easily invade the inside of the main cable, which will also cause the corrosion of the loose cable and the main cable. Service life of the main cable and scatter casing
