[0041] Please refer to Figures 1 to 5, the inventor provides a hydraulic support at the end of a fully-mechanized coal mining face with a roof beam that can be adjusted at all angles, including a support assembly 10 and an assembly connection device 20. The support assembly 10 includes a base 11, a vertical telescopic rod 12, a support frame 13, an end support member 14, and a steering hinge member 15. The number of vertical telescopic rods 12 is more than two. One end of the vertical telescopic rod 12 is rotatably connected to the support frame 13 through a socket and a cap, and the other end is connected to the base 11 through a socket and a cap. The end support member 14 is hinged to the base 11 through a bracket. The steering hinge member 15 includes a first hinge portion 16 and a second hinge portion 17. The hinge rotation directions of the first hinge portion 16 and the second hinge portion 17 are staggered with each other on the projection plane. The first hinge portion 16 of the steering hinge member 15 is hinged to the end support member 14, and the second hinge portion 17 of the steering hinge member 15 is hinged to the support frame 13. The assembly connection device 20 includes a horizontal telescopic rod 21, and both ends of the horizontal telescopic rod 21 are respectively connected to a support assembly 10.

[0042] According to the above structure, during the use of the end hydraulic support in the fully mechanized mining face where the top beam can be adjusted at all angles, when one of the support assemblies 10 is lifted by the elongation of multiple vertical telescopic rods 12, the corresponding support frame 13 is pushed to lift and contact the area to be supported. During the contact process, the length of the extended vertical telescopic rods 12 is relied on to adjust the adaptation between the support frame 13 and the area to be supported. Meanwhile, during the lifting process of the support frame 13, the support frame 13 realizes the angle adaptation between the steering hinge 15 and the support frame 13 through the second hinge part 17. The first hinge part 16 of the steering hinge 15 adapts to the junction area of the end support member 14, so that when the support frame 13 adapts to the top support area, the end support member 14 can be deployed without interference. When the end support member 14 rotates along the hinge point with the base 11 or is hinged to the base 11 through the corresponding adapted hinge bracket, the area to be supported near the base 11 is expanded and abutted. During the angle adjustment process, the socket and cap structure used when the end of the vertical telescopic rod 12 is connected to the support frame 13 enables the angle between the support frame 13 and the vertical telescopic rod 12 to be changed and adapted. Subsequently, the horizontal telescopic rod 21 is driven. One of the support assemblies 10 remains relatively stationary, and the other support assembly 10 is pushed forward by the horizontal telescopic rod 21 to move to the next support direction, and the vertical telescopic rod 12 is pushed and the support frame 13 is supported. When the support assembly 10 needs to be lowered, the distance between the two support assemblies 10 is shortened to facilitate the next movement. The vertical telescopic rod 12 of the support assembly 10 is lowered, driving the support frame 13 to leave the support area. Subsequently, the horizontal telescopic rod 21 of the assembly connection device 20 contracts, pulling the lowered support assembly 10 towards the support assembly 10 that is still in the support state and whose support frame 13 supports the support area. By setting the vertical telescopic rod 12, the support frame 13 can be rotatably connected through the socket and cap structure. During the lifting process, the support frame 13 can adapt to the uneven top surface of the area to be supported, and during the lifting process, the vertical telescopic rod 12 is linked to assist in expanding and supporting the end, greatly improving the adaptability to the support surface and the adapted support area of the end area.
