[0033] like Figure 1 As shown, a triangular slide device of a top coal caving hydraulic support includes: a tail beam triangular slide rail 2 arranged on a tail beam 1 and a plug-in plate triangular slide 4 arranged on a plug-in plate 3, wherein the tail beam triangular slide rail 2 is arranged above the plug-in plate triangular slide rail 4 and is slidably connected to the plug-in plate triangular slide rail 4.

[0034] In the above scheme, two tail beam triangular slide rails 2 are provided, which are respectively arranged on both sides of the tail beam 1, and two three slideways of the plug board 3 are also provided, which are respectively located on both sides of the plug board 3 and correspond to the tail beam triangular slide rails 2. A tail beam 1 jack is provided on the tail beam 1, and the tail beam 1 is driven to slide by the extension and contraction of the tail beam 1 jack. A plug board 3 jack is provided on the inner side of the two plug board triangular slideways 4 in the plug board 3, and the plug board 3 is driven to slide by the extension and contraction of the plug board 3 jack.

[0035] In order to ensure the service life and use effect, the tail beam triangular slide rail 2 and the insert plate triangular slideway 4 are both made of steel or other metal materials with strong rigidity.

[0036] Through the above scheme, the tail beam triangular slide rail 2 and the plug plate triangular slideway 4 can slide with each other to realize the relative sliding of the plug plate 3 and the tail beam 1. The tail beam triangular slide rail 2 and the plug plate triangular slideway 4 have simple structures and are easy to manufacture, saving material costs. In addition, the triangular structure is stable and can play a stable guiding function, thereby improving the load-bearing capacity and bending resistance of the plug plate 3.

[0037] In a specific embodiment, the tail beam triangular slide rail 2 is a V-shaped triangular slide rail opening upward, and the insert plate triangular slideway 4 is a V-shaped triangular slideway matching the V-shaped triangular slide rail.

[0038] In the above scheme, there is a groove in the V-shaped triangular slide, and the V-shaped triangular slide rail has a protrusion corresponding to the groove. When connected, the protrusion just falls into the groove, which can ensure that the V-shaped triangular slide rail slides in the V-shaped triangular slide and avoid derailment during sliding.

[0039] In a specific embodiment, the V-shaped triangular slide includes: a first slide side plate 41, a second slide side plate 42, a first slide inclined plate 43 and a second slide inclined plate 44. A slide mounting groove is provided on the plug plate 3. The first slide side plate 41 and the second slide side plate 42 are fixed on both sides of the slide mounting groove. The top of the first slide inclined plate 43 is fixed to the top of the first slide side plate 41, and the top of the second slide inclined plate 44 is fixed to the top of the second slide side plate 42. The bottoms of the first slide inclined plate 43 and the second slide inclined plate 44 intersect and are fixed on the inner sides of the first slide side plate 41 and the second slide side plate 42.

[0040] In the above scheme, the first slideway side plate 41 and the second slideway side plate 42 are used to fix the first slideway inclined plate 43 and the second slideway inclined plate 44, and the tops of the first slideway inclined plate 43 and the second slideway inclined plate 44 are respectively welded to the first slideway side plate 41 and the second slideway side plate 42 to form an integrated structure.

The first slide inclined plate 43 and the second slide inclined plate 44 are intersected and fixed on the slide fixing plate 45 at the bottom.

[0042] In the above scheme, since the slideway installation groove on the plug board 3 is relatively deep, in order to ensure that the first slideway inclined plate 43 and the second slideway inclined plate 44 can be better fixed, a slideway fixing plate 45 needs to be provided, and the slideway fixing plate 45 is welded to the middle of the first slideway side plate 41 and the second slideway side plate 42 as a whole, thereby further ensuring the stability of the V-shaped triangular slideway.

[0050] In the above scheme, the tops of the third slideway inclined plate 46 and the fourth slideway inclined plate 47 are welded as one, and the bottoms are respectively arranged on both sides of the slideway mounting groove of the insert plate 3, so as to ensure the formation of an inverted V-shaped triangular protrusion.

[0051] In addition, in order to better fix the third slide inclined plate 46 and the fourth slide inclined plate 47, a slide fixing plate 45 can also be set at the bottom, so that after the bottom of the third slide inclined plate 46 and the fourth slide inclined plate 47 are welded to the slide fixing plate 45 as a whole, the slide fixing plate 45 is installed in the corresponding position (for example, the middle) in the slide mounting groove.

[0052] In a specific embodiment, the inverted V-shaped triangular slide rail includes: a first slide rail side plate 24, a second slide rail side plate 25, a third slide rail inclined plate 26, and a fourth slide rail inclined plate 27.
