[0027] The technical scheme of the utility model is described in further detail below through specific embodiments.

[0028] As Figures 1-7As shown, the ultra-long telescopic top beam structure of the filling hydraulic support of this utility model includes a rear top beam 10, which serves as part of the top beam structure of the hydraulic support and is used to complete the support operation. A telescopic box 11 is fixedly installed on the rear top beam 10, extending along the length direction of the rear top beam 10. The telescopic box 11 serves as part of the main load-bearing structure beam on the rear top beam 10, and plays a role in bearing and supporting the load. The opening of the box 11 is located at the rear end of the rear top beam 10. A telescopic beam 20 is slidably installed at the rear of the rear top beam 10. A portion of the telescopic beam 20 extends into the telescopic box 11 from the opening, allowing one end of the telescopic beam 20 to slide inside the telescopic box 11, while the other end of the telescopic beam 20 is located outside the telescopic box 11. The telescopic beam 20 extends and retracts outward from the rear of the rear top beam 10 along its length direction to extend the support range of the rear top beam 10.

[0029] A rear column socket 12 is fixedly provided at the bottom of the telescopic box 11. The rear column socket 12 is used to connect the rear column of the hydraulic support. The telescopic box 11 is used as part of the main load-bearing structure on the rear top beam 10. The rear column socket 12 is set at the bottom of the telescopic box 11. The length of the telescopic box 11 can be set as long as possible within the limited length of the rear top beam 10, which breaks through the limitation of setting an ultra-long telescopic beam structure. Therefore, the length of the telescopic beam structure can be maximized, thus forming the ultra-long telescopic top beam structure of the filling hydraulic support of this utility model.

[0030] In one embodiment, the rear top beam 10 serves as part of the top beam structure of the hydraulic support. The top beam structure can be a split structure, such as a structure in which the rear top beam 10 and the front top beam are hinged. Specifically, the rear top beam 10 is provided with a hinge arm 13, which is rotatably connected to the hinge seat on the front top beam. The hinge arm 13 and the telescopic box 11 serve as two parts of the structural main beam on the rear top beam 10. Connecting the hinge arm 13 to the telescopic box 11 allows the load-bearing main beam to extend through the length of the rear top beam 10, thereby enhancing the overall structural strength of the rear top beam 10.

[0031] In one embodiment, the top beam structure can also be an integral structure, in which case the rear top beam 10 is the rear half of the integral top beam structure, and the telescopic box 11 is part of the load-bearing main beam on the rear top beam 10. The telescopic box 11 is connected to the load-bearing main beams of other parts of the top beam structure, so that the load-bearing main beams can run through the length of the top beam structure.

[0032] In one embodiment, as a common structural form of hydraulic supports, such as Figure 2As shown, two telescopic box bodies 11 are arranged on the rear roof beam 10, and two rear stand column sockets 12 and two hinge arms 13 are arranged corresponding to the two telescopic box bodies 11, and the two rear stand column sockets 12 are respectively connected to two rear stand columns of the hydraulic support.

[0033] As shown, Figure 2 The telescopic beam 20 includes a telescopic main beam 21 and an end connecting beam 22, the telescopic main beam 21 is slidingly arranged in the telescopic box body 11, and the telescopic main beam 21 abuts against the four surrounding side walls of the telescopic box body 11, when the telescopic main beam 21 slides out a part from the telescopic box body 11, the telescopic box body 11 can still effectively support the telescopic main beam 21, and the telescopic main beam 21 itself serves as a structural main beam of the telescopic beam 20, so that the telescopic beam 20 as a whole plays a supporting role; the end connecting beam 22 is used for connecting one end of the plurality of telescopic main beams 21 outside the telescopic box body 11, so that the plurality of telescopic main beams 21 become a whole structure.

[0034] Based on the above, two telescopic main beams 21 are arranged in a single telescopic box body 11, which can reduce the use of materials and the overall weight on the premise of ensuring the structural strength of the telescopic main beam 21; the two telescopic main beams 21 in a single telescopic box body 11 are arranged side by side in the length direction of the telescopic beam 20; the top end surface of the two telescopic main beams 21 in a single telescopic box body 11 is also provided with a connecting plate 25, which plays an auxiliary supporting role; the space between the two telescopic main beams 21 in a single telescopic box body 11 can also be provided with a telescopic beam jack 23, and the two ends of the telescopic beam jack 23 are respectively connected with the telescopic box body 11 and the end connecting beam 22.

[0035] As shown, Figure 2 The telescopic beam 20 is also provided with a top protection plate 24, the top protection plate 24 is fixedly connected with the end connecting beam 22, the top protection plate 24 is arranged on the telescopic beam 20 at a position between the two telescopic box bodies 11, there is a gap between the top protection plate 24 and the telescopic main beam 21 to prevent interference during telescoping, and the top protection plate 24 is used for auxiliary support.

[0036] The telescopic beam 20 is hingedly provided with a protection plate 30 at the rear end, the protection plate 30 is used for increasing the supporting range of the telescopic beam 20, the protection plate 30 can be arranged on the end connecting beam 22 at the rear end of the telescopic beam 20, the protection plate 30 telescopes with the telescopic beam 20, the protection plate 30 can also rotate relative to the telescopic beam 20, after the telescopic beam 20 is unfolded to the limit position, the protection plate 30 is rotated and opened on the telescopic beam 20, so as to further increase the supporting range of the telescopic beam 20. In other embodiments, a two-stage telescopic structure can be used instead of the protection plate 30.

[0037] In one embodiment, the telescopic beam 20 is further provided with a support plate 31, which can be disposed in the space between the two telescopic boxes 11. The end of the support plate 31 can be connected to the end connecting beam 22 of the telescopic beam 20. The support plate 31 is provided with a side jack 32 for driving the side plate 30 to rotate. The two ends of the side jack 32 are respectively hinged to the side plate 30 and the support plate 31, so that the side plate 30 can rotate. In other embodiments, the side jack 32 can be disposed on the top protection plate 24, and the two ends of the side jack 32 are respectively hinged to the top protection plate 24 and the side plate 30.

When the telescopic beam 20 extends and the side guard plate 30 opens, the telescopic beam 20 or the side guard plate 30 is located on the upper side of the isolation mechanism 40, which can support the isolation mechanism 40. When the telescopic beam 20 retracts and the side guard plate 30 closes, the telescopic beam 20 and the side guard plate 30 are located inside the isolation mechanism 40. At this time, the telescopic beam 20 and the side guard plate 30 will not interfere with the lifting of the isolation mechanism 40, so as to complete the filling operation smoothly. When the filling is completed and the hydraulic support is moved, the telescopic beam 20 extends and the side guard plate 30 opens, completing the support for the rear overhang space.

[0039] This utility model discloses an ultra-long telescopic top beam structure for a filling hydraulic support. The telescopic beam 20 can extend and retract outward from the rear of the rear top beam 10 to increase the support range of the rear top beam 10. The side guard plate 30 rotates and opens on the telescopic beam 20 to further increase the support range of the rear top beam 10, giving the filling hydraulic support good support flexibility. The telescopic box 11 is used as part of the main load-bearing structure on the rear top beam 10, and the rear column socket 12 is set at the bottom of the telescopic box 11. The length of the telescopic box 11 can be set as long as possible within the limited length of the rear top beam 10, breaking through the limitation of setting an ultra-long telescopic beam structure. Therefore, it has an ultra-long telescopic range, which meets the mining requirements of large-step filling process. The telescopic box 11 is used as part of the main load-bearing structure on the rear top beam 10, and the telescopic main beam 21 of the telescopic beam 20 is slidably set in the telescopic box, so that the rear top beam 10 and the telescopic beam 20 have high structural strength.
