Problems solved by technology
Moreover, the cables are thick and heavy, and multiple people are required to cooperate with the suspension. The tensioning of the plastic-coated steel wire rope also requires an additional tensioning device or a hand chain hoist, which is time-consuming, laborious and material-intensive.
[0003] It can be seen that for the operation of the roadheader on the fully mechanized excavation face, the excavation speed is very fast, and the belt tail is pulled frequently. Since there has been no fast and convenient method and equipment, there has always been a problem that the second transportation cable of the roadheader cannot be hoisted in time. problem, and it is also a very annoying task for comprehensive excavation

The invention discloses an automatic feeding and retracting device for a secondary conveyor cable of a heading machine. The automatic feeding and retracting device comprises a plastic coated steel wire rope and a transfer bridge located on the heading machine and is characterized in that an upper pulley and a lower pulley are respectively arranged on the transfer bridge. A supporting pulley is arranged at the tail end of the heading machine. The front end of the plastic coated steel wire rope is fixed at the front end of the heading machine, and then the plastic coated steel wire rope is sequentially wound on the lower pulley, an upper sliding ring and the supporting pulley and then is fixedly connected to the rear end of the heading machine. The plastic coated steel wire rope located between the upper pulley and the supporting pulley is provided with multiple hanging rings, and the secondary conveyor cable is sequentially and spirally wound the hanging rings and then is connected to a transfer bridge circuit. Compared with the prior art, the automatic feeding and retracting device has the advantages of being small in labor intensity, high in heading efficiency and speed, safe and convenient.
Description
technical field [0001] The invention relates to a warp-wrapping shrinking device for cables, in particular to a self-feeding shrinking device for the second transport cable of a roadheader which is fixed at the front and back and winds around a pulley in the middle. Background technique [0002] The original roadheader cable suspension was to tension the plastic-coated steel wire rope on the support anchor of the roadway roof. Due to the limited length of the plastic-coated steel wire rope, the average daily hanging of the plastic-coated steel wire rope, tensioning of the plastic-coated steel wire rope, and cable suspension once. Moreover, the cables are thick and heavy, and multiple people are required to cooperate with the suspension. The tensioning of the plastic-coated steel wire rope also requires an additional tensioning device or a chain block, which is time-consuming, laborious and material-intensive. [0003] It can be seen that for the operation of the roadheader ...
