Releasing device for cable laying in tunnel and using method thereof

Abstract

The invention discloses a releasing device for cable laying in a tunnel and a using method thereof. The device comprises a right triangle frame structure, a cable pulley and a cable feeding angle adjusting structure, wherein the cable pulley is arranged on the bevel edge of the right triangle frame structure and used for transporting a cable; the cable feeding angle adjusting structure is arrangedat the junction of the bevel edge and the vertical edge of the right triangle frame structure and used for adjusting the horizontal angle of the tail end of the cable and guiding the cable to a cablerack; the right triangle frame structure comprises telescopic rods; the telescopic rods are arranged on the bevel edge and the vertical edge of the right triangle frame structure respectively and areused for adjusting the height of the releasing device. According to the releasing device, all the components are detachably connected, assembling difficulty is low, and working efficiency can be effectively improved; meanwhile, the upper end of the cable feeding angle adjusting structure is movably connected, only the weight of a small section of cable is borne in the using process, borne load issmall, and the risk of rollover of a cable laying vehicle is avoided.

Description

technical field [0001] The invention relates to the technical field of automatic lifting and transportation, in particular to a device for laying cables in tunnels and a method for using the same. Background technique [0002] At present, during the cable laying process of the transmission and distribution network, it is necessary to carry the cable from the ground to the cable rack by manpower. Due to the heavy weight and long length of the cable itself, about 20 manpower are required to carry the cable in sections, and the whole process costs a lot of money. manpower and time. [0003] And various cable laying devices in the prior art, though contribute to the release of cable lines, have the following problems: [0004] 1) The structure of the existing cable laying device is relatively complex, and the volume is large, and the cable tunnel is narrow. The laying device often needs to be installed on site according to the local environmental conditions. It is difficult to ...
