Description

Trapezoidal adjustable flexible coaster of cable laying

Technical Field

The utility model relates to an adjustable flexible coaster of cable laying trapezoidal belongs to cable laying technical field.

Background

In recent years, with the aging and updating demands of cables, a great amount of cable updating and replacing projects will appear in various cities. Because the tunnel is narrow and small, the working surface is narrow, and can not replace all the old cables once when replacing the cables, but replace the old cables in batches and in batches, the construction difficulty is increased. Moreover, the power cable is touched and damaged in personnel construction, so that loss is caused to power supply reliability and personal and property safety. Therefore, under the condition that similar standard operation flows and construction processes do not exist, the paying-off support is used, so that the operation of constructors is facilitated, and the smooth completion of cable laying is facilitated.

SUMMERY OF THE UTILITY MODEL

In order to solve the defects of the prior art, the utility model provides a cable laying ladder-shaped adjustable telescopic pulley, which can fully ensure that the replaced cable is not damaged and ensure the integrity and the use function of the cable; the laying of cables at the S-shaped bend in the tunnel can be adapted, and the smooth construction of cable replacement is ensured; greatly improves the working efficiency and saves more than 80 percent of labor.

The utility model provides a technical scheme that its technical problem adopted is: a cable laying trapezoidal adjustable telescopic pulley comprises upright post angle steel, cross beam angle steel, a fixed block, a lead screw and a limiting wheel; the upper end, the middle end and the lower end of each of the two stand column angle steels are fixedly connected through the cross beam angle steel respectively, the two ends of each of the two stand column angle steels are fixedly connected with fixing blocks, the fixing blocks are provided with threaded holes, the fixing blocks are in threaded connection with the lead screws, the two ends of each limiting wheel are connected with the two stand column angle steels through bolts and nuts respectively, the hexagonal prism is arranged in the middle of each lead screw, and the two stand column angle steels are provided with a plurality of symmetrical bolt through.

At tunnel S type bend department, the adjustable flexible coaster level of trapezoidal is placed, through screwing up the lead screw, and the level is fixed in the tunnel, because the characteristics of S type bend, the cable can be close to tunnel S type bend convex surface department when passing S type bend, so adjust spacing round to be close to tunnel S type bend convex surface department, protection and spacing to the cable.

The utility model has the advantages that: the utility model can fully ensure that the replaced cable is not damaged, and ensure the integrity and the use function of the cable; the laying of cables at the S-shaped bend in the tunnel can be adapted, and the smooth construction of cable replacement is ensured; if an S-shaped bend is encountered, the effective control of the cable can be guaranteed; greatly improves the working efficiency and saves more than 80 percent of labor.

Detailed Description

As shown in fig. 1-3, the cable laying ladder-type adjustable telescopic pulley comprises upright post angle steel 11, beam angle steel 12, a fixed block 13, a lead screw 14 and a limiting wheel 15; the upper end, the middle end and the lower end of each of the two upright post angle steels 11 are fixedly connected with one another through a beam angle steel 12 respectively, the two ends of each of the upright post angle steels 11 are fixedly connected with fixing blocks 13, the fixing blocks 13 are provided with threaded holes, the fixing blocks 13 are in threaded connection with lead screws 14, hexagonal prisms are arranged in the middles of the lead screws 14, the two ends of the limiting wheel 35 are connected with the two upright post angle steels 11 through bolt nuts respectively, a plurality of symmetrical bolt through holes are formed in the two upright post angle steels 11, and the.

Detailed description of the preferred embodiment

At tunnel S type bend 3 department, adjustable flexible coaster 1 level of trapezoidal is placed, through screwing up lead screw 14, and the level is fixed in the tunnel, because the characteristics of S type bend, cable 2 can be close to tunnel S type bend 3 convex surface department when passing S type bend, so adjust spacing wheel 15 to be close to tunnel S type bend 3 convex surface department, to the protection of cable 2 with spacing.
