Fully enclosed telescopic safety protection device of transloading machine

Abstract

The invention relates to a mining device and particularly relates to a fully enclosed telescopic safety protection device of a transloading machine. The fully enclosed telescopic safety protection device comprises a fully enclosed sliding plate which can slide forward and backward, wherein the cross section of the fully enclosed sliding plate is in the shape of L which is rotated 180 degrees, thehorizontal part of the fully enclosed sliding plate is slidably mounted between an upper sealing cover plate and a lower sealing cover plate, the vertical part of the fully enclosed sliding plate is positioned on the outer side of a coal blocking plate of the transloading machine, and a driving device of the fully enclosed sliding plate is mounted on the lower sealing cover plate. The fully enclosed telescopic safety protection device has the beneficial effects that the openings of the noses of a front scraper conveyor and a rear scraper conveyor are fully sealed, and operation staff can enter into the place above the upper sealing cover plate of the transloading machine for working during the normal operation process of the transloading machine and be prevented from falling into the transloading machine, thereby providing a working platform for working staff, not only being convenient to operate, but also ensuring the safety of the operation staff. The device adopts a hydraulic control advanced technology for performing automatic control. The device can play a role in indirect reduction of secondary coal dust.

Description

technical field [0001] The invention relates to mining equipment, in particular to a safety protection device for the open area at the overlapping joint between a loader on a fully mechanized mining face and front and rear scraper conveyor heads, that is, a fully enclosed telescopic safety protection device for a loader. Background technique [0002] During the normal operation of the transfer machine, since the transfer machine is in front of the working surface, the scraper conveyor head at the rear and the transfer machine overlap the transfer place, during the production process of the working surface, the two heads and the high sealing plate of the transfer machine The inner side of the transfer machine is exposed, and there are unsafe factors during the operation of the equipment, and personal accidents may occur due to the failure of fully enclosed protection for the operating equipment. Contents of the invention [0003] In order to make up for the defi...
