Problems solved by technology

Due to the limited length of each middle slot, the straight plate must be pulled along the width direction of the middle slot, and the two parallel lower chains in the chain channel directly above the bottom plate are set along the length direction. It is impossible to draw out most of them to reach the required range, that is, only a small part can be drawn out, and only one down chain can be observed through the skylight at most, and the situation of two down chains cannot be observed at the same time, but the situation of the chain must be observed Observing two down chains at the same time can relatively accurately judge the actual situation of the chain. Therefore, this method severely limits the observation of the chain.

Embodiment 1

[0032] Please see 1 to 4 Furthermore, the middle slot 10 of the rotary skylight of the scraper loader used in the underground coal mine further comprises a reinforcing plate 80, both ends of which are fixedly connected with the bottom plate 20, and the reinforcing plate 80 is located just below the observation window 30, and the reinforcing plate 80 is rotatably connected with the vertex of the observation window 30 to provide the rotation fulcrum of the observation window 30 through the reinforcing plate 80, and the surface of the reinforcing plate 80 is in contact with the surface of the observation window 30 to support the observation window 30 through the reinforcing plate 80.

Embodiment 2

[0034] Please see Figs. 4 to 9 Furthermore, the middle slot 10 of the rotary skylight of the scraper conveyor used in the coal mine underground gateway further includes a reinforcing frame 90, which is a sector frame and fixed on the bottom plate 20. The reinforcing frame 90 is located right below the observation window 30, and two straight sides of the reinforcing frame 90 are attached to the edge of the observation port 21. The vertex of the observation window 30 is rotatably connected with the vertex of the reinforcing frame 90, so as to provide the rotation fulcrum of the observation window 30 through the reinforcing frame 90, and the surface of the reinforcing frame 90 is reinforced.

[0035] Furthermore, the distance between the curved edge of the reinforcing frame 90 and its apex is smaller than that between the curved edge of the observation port 21, and there is a lateral gap between the curved edge of the reinforcing frame 90 and the curved edge of the observation port 2...

Abstract

The invention discloses a scraper reversed loader rotary skylight opening middle groove for underground coal mine crossheading, and relates to the technical field of middle grooves. The scraper reversed loader rotary skylight opening middle groove comprises a bottom plate provided with an observation opening and an observation window arranged on the bottom plate. Lower chains are located above thebottom plate. The observation window is matched with the observation opening, the observation window is arranged at the observation opening, and the observation window is in a fan shape. The vertex of the observation window and the bottom plate can rotate relative to the plane. The connecting line of the two end points of the rotating track from 0 degree plane to 90 degree plane of the observation window is parallel to the width direction of the bottom plate. The observation window is also opened and closed in the width direction of the middle groove, but due to the fan-shaped design of the observation window and the design that the observation window rotates with the vertex of the observation window as the axis plane to open and close the observation opening, the two lower chains can beobserved at the same time when the observation window rotates by any angle within the range of 0-90 degrees, and even if the underground width space is small, the situation of the two lower chains canbe observed at the same time by rotating the observation window by a small angle.

Description

Technical field [0001] The invention relates to the technical field of the middle trough, in particular to a middle trough with a rotary skylight of a scraper loader used for underground gateway in a coal mine. technical background [0002] With the increase of mining speed of coal resources and the requirement of mining safety of coal resources, in order to effectively improve the operability, reliability and maintenance convenience of equipment, and reduce the failure rate of transportation equipment in working face, it is necessary to observe the chain track in real time. Therefore, it is necessary to open an observation window at a certain part of the loader. Looking at all parts of the loader, the middle slot is located in the suspended section of the loader because of its special setting position, which is very suitable for manual observation of the chain track. [0003] At present, the skylight opened in the middle slot is rectangular or square, and the opening and closing...
