Problems solved by technology

[0002] The single trolley used in the traditional large-section power cable pay-off has the disadvantage that each single trolley must be fixed to the ground. Depending on the terrain, it may not be completely fixed firmly, and the number of rivets used is large.
Due to the heavy weight of the large-section cable itself, the single pulley is prone to roll over during the pay-off, and the deviation is misplaced, which makes it difficult to pay-off the cable and damages the contact with the ground.

Embodiment Construction

[0015] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0016] Such as figure 1 As shown, the row blocks for large-section cable payout of the present invention include several individual blocks 1, and the individual blocks 1 are connected in series, and the adjacent individual blocks 1 are connected by a steel block fixing plate. 2 are connected to each other, and the single tackle 1 at both ends is connected with two steel rope sleeves 4 respectively. The single block 1 includes a pulley 11 and a supporting iron plate 12, the supporting iron plate 12 is composed of two triangular side plates 121 and a rectangular bottom plate 122, and the two triangular side plates 121 are welded on the rectangular bottom plate 122 Two triangular side plates 121 are connected to the pulley 11 by bolts on both sides of the pulley. Both ends of the tackle fixing plate 2 are provided with screw holes, and the tackle fixing plate 2 and the...

Abstract

The invention relates to a connection row pulley for large-section cable paying off. The connection row pulley comprises a plurality of single pulley bodies, adjacent single pulley bodies are connected through pulley fixing boards, the single pulley bodies at the head end and the tail end are respectively connected with a steel rope sleeve, each single pulley body comprises a pulley wheel and a supporting iron board, each supporting iron board is composed of two triangular side boards and a rectangular bottom board, and the side boards are connected with the pulley wheels through bolts. According to the connection row pulley, the plurality of single pulley bodies are connected through the pulley fixing boards in series, the length of each connection row pulley can achieve 10-20 meters, and rolling and malposition of each single pulley body are avoided. Contacting areas of the pulley wheels and cables are greatly enlarged, a paying off process is smooth, the pulley fixing boards are made of steel, bearing performance of the connection row pulley is increased, the pulley fixing boards are connected with the single pulley bodies through the bolts, and installation, disassembly and conveying are convenient and rapid.

Description

technical field [0001] The invention relates to a row block for large-section cables. Background technique [0002] The single trolley used in the traditional large-section power cable pay-off has the disadvantage that each single trolley must be fixed to the ground. Depending on the terrain, it may not be completely fixed firmly, and the number of rivets used is large. Due to the heavy weight of the large-section cable itself, the single pulley is prone to roll over and deviate from the position during the pay-off, which makes it difficult to pay-off the cable and damages the contact with the ground. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a row block for large-section cable payout, so that the large-section cable can be unwound smoothly and will not be damaged by friction. [0004] In order to solve the problems existing in the prior art, the technical solution adopted in the present invent...
