Detailed description of the invention
Below in conjunction with accompanying drawing, this patent utility model is described further
As shown in Figure 1, Figure 2, a kind of hydraulic support tilting prevention device shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Figure 10, Figure 11.
Back timber is respectively one grade with middle-grade, two caps the width of back timber is divided into third gear, the trend of each grade is that rear end from back timber is until front end.
Affiliated anti-down sleeve (2), the place of certain distance is had to drill hole in its distance aperture, one end, for hole (10), by perforate on the cover plate of the cap two grades of back timber front end, the position longitudinal direction in hole has certain distance from cap, there is certain distance horizontal direction distance back timber front end, this needs the stroke changing anti-down jack just can arrive requirement, the size in hole can be held anti-down sleeve (2) and pass, by in the patchhole of anti-down sleeve (2) one end, anti-down sleeve (2) is drilled with one end of perforation (10) outwardly, in a welding manner anti-down sleeve (2) is welded on back timber.
Described connection gudgeon (3), there is engaging lug its one end, engaging lug there is perforation (11), on axle below engaging lug, the place lathe car of certain distance has U-type groove (12), one end of engaging lug is not had to insert in anti-down sleeve (2) by connecting gudgeon (3), make the planes overlapping at hole (10) place on the plane at U-type groove (12) place, center and anti-down sleeve (2), with U-shaped pin (4) successively through the hole (10) on anti-down sleeve (2), connect the U-type groove (12) on gudgeon (3), affiliated U-shaped pin (4), perforation (13) is had what have a ground drill with ferrule of certain distance apart from its both ends of the surface, with the first cottor pin (7) through the fixing U-shaped pin (4) in the hole (13) on U-shaped pin (4), thus make connection gudgeon (3) axial restraint, really to be rotated about axis,
One end of described anti-down jack (6) is by bearing pin (5), second cottor pin (8), packing ring (9) is connected gudgeon (3) with one hinged, wherein, affiliated bearing pin (5), the place of certain distance is had to be drilled with bore a hole (14) at its little extreme direction and small end face, one end of anti-down jack (6) is placed between two ears connecting gudgeon (3), bearing pin (5) is successively through the hole (11) connected on gudgeon (3), the hole (15) of anti-down jack (6) one end or hole (16), packing ring (9), the second cottor pin (8) is finally used to fix through the hole (14) on bearing pin (5), the other end of described anti-down jack (6) with above identical articulated manner with adjacent frame, nearest one to link gudgeon hinged.
