Description

Technical Field

[0001] This utility model relates to the field of coal mining equipment technology, and in particular to a fluid supply regulation device for fully mechanized mining faces. Background Technology

[0002] A coal mine is an area where humans extract coal resources in coal-rich areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, tunnels are typically dug underground to extract the coal; this is called an underground coal mine.

[0003] Fully mechanized coal mining refers to the mechanization of basic processes such as coal breaking, loading, transportation, support, and post-mining goaf treatment in a coal mining face. Such a working face is called a fully mechanized coal mining face, or simply a longwall mining face. Longwall mining faces use a variety of mechanical equipment, among which hydraulic mechanical equipment is indispensable.

[0004] Hydraulic machinery uses a hydraulic station to pump hydraulic oil and also controls the pumping process. Typically, the hydraulic pumping control area of ​​a hydraulic station is located at the top, leaving it unprotected. Objects falling from above the longwall face can easily damage this area.

[0005] In view of this, we propose a fluid supply regulation device for fully mechanized mining faces. Utility Model Content

[0046] Furthermore, the top of the gantry frame 5 is positioned and engaged with the insertion block 601 via the positioning structure 8;

[0047] The positioning structure 8 includes a through plate 802, a connecting plate 801, and a handle 804.
