Consignment vehicle for coal mine

Abstract

The invention discloses a consignment vehicle for a coal mine. The consignment vehicle for the coal mine comprises a consignment vehicle body and a mechanical arm movably arranged on the consignment vehicle body, the mechanical arm is stretchable, the free end of the mechanical arm is provided with a rotatable rotating connecting piece, and the rotating connecting piece is used for being connected with a base of a hydraulic support. The consignment vehicle for the coal mine, which is provided with the mechanical arm, is adopted to replace a prop pulling winch and a single hydraulic prop, the hydraulic support is removed, and integrated continuous operation of pulling out and dragging of the hydraulic support is achieved; compared with a steel cable hard dragging hydraulic support adopting the prop pulling winch in the prior art, the mechanical arm is large in structural strength and high in safety, and therefore construction safety is improved; and a steel cable does not need to be manually pulled to the removed support or the single hydraulic prop is manually carried and arranged, so that the labor intensity of workers is reduced, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of coal mine machinery and equipment, and more particularly, to a coal mine consignment vehicle. Background technique [0002] At present, there are usually two methods for the removal of hydraulic supports in fully mechanized coal mining face, namely: direct removal method and cover removal method. [0003] In the prior art, no matter whether the hydraulic support is removed by the direct removal method or the cover removal method, the hydraulic support is pulled out by the back-column winch and the steel cable or the hydraulic support is pulled out in the form of a single hydraulic support and a winch, and then the winch is used. Drag the hydraulic support to the working face loading platform or the loading chamber along the groove for loading and transportation. [0004] However, with the gradual development of the mine in the direction of large-scale, the type of hydraulic support used is also becoming ...

AI Technical Summary

Problems solved by technology

[0004] However, as the mine gradually develops toward large-scale development, the type of hydraulic support used is also getting larger and larger, and the weight of the hydraulic support is getting heavier and heavier. When the hydraulic support is removed by winch cable dragging, it is easy to cause Steel cables, hooks or pulleys, etc. slip or break, which is poor in safety and easy to cause injury to personnel. In the actual construction process, even if various protective measures are taken, safety accidents still inevitably occur from time to time

Moreover, if there is no return winch on the working surface, it is necessary to manually pull the steel cable to the removed support; when using a single hydraulic prop to assist in steering, it is necessary to manually carry and arrange the single hydraulic prop, etc., which is labor-intensive. Low construction efficiency
