[0027] Example:

[0028] A rapid support device for mine roadways, please refer to the appendix. Figure 1 -Appendix Figure 3 As shown, the device includes a column 1, a side support cylinder 2, and a movable beam 3. The upper end of the column 1 is fixed with a top beam 4, and the lower end of the column 1 is provided with a claw seat 5 for fixing the column 1 to the ground. The fixed end of the side support cylinder 2 is hinged with a toothed plate 6. The toothed plate 6 is slidably arranged along the length direction of the column 1 and can be fixed on the column 1. One end of the movable beam 3 is provided with a hinge lug 10. The telescopic end of the side support cylinder 3 is hinged to one end of the movable beam 3 through the hinge lug 10. The other end of the movable beam 3 is hinged to the end of the top beam 4 away from the column 1. The movable beam 3 and the top beam 4 are also provided with a limiting mechanism for fixing the movable beam 3 to the top beam 4.

[0029] The limiting mechanism includes a top beam limiting hole 4.1 on the top beam 4, a movable beam limiting hole 3.1 on the movable beam 3, and a limiting pin 7. The limiting pin 7 passes through the top beam limiting hole 4.1 and the movable beam limiting hole 3.1 to fix the movable beam 3 on the top beam 4.

[0030] The column 1 includes a vertical support cylinder 1.2 and a protective cover 1.1 sleeved on the vertical support cylinder 1.2. A top beam 4 is fixed on the protective cover 1.1 and is perpendicular to the protective cover 1.1. The top surface of the top beam 4 is flush with the top surface of the protective cover 1.1. A limiting shaft 8 is provided on the outer wall of the vertical support cylinder 1.2. The protective cover 1.1 is provided with a U-shaped groove 1.3. The limiting shaft 8 is sleeved in the U-shaped groove 1.3. A limiting plate 9 for fixing the limiting shaft 8 in the U-shaped groove 1.3 is also fixed on the outer wall of the protective cover 1.1. The limiting plate 9 is fixed on the protective cover 1.1 by fixing bolts. Through the above structure, the protective cover 1.1 can be firmly fixed on the vertical support cylinder 1.2. The claw seat 5 is fixed to the telescopic end of the vertical support cylinder 1.2 by a pin. The protective cover 1.1 is also provided with a hydraulic oil pipe interface 1.4 communicating with the vertical support cylinder 1.2.

[0031] A sliding plate 11 and a toothed seat 12 are fixedly provided on the outer wall of the protective cover 1.1. There is a movable gap 13 between the sliding plate 11 and the protective cover 1.1. The toothed seat 12 is placed in the movable gap 13. The sliding plate 11 is provided with a sliding groove 11.1. The toothed plate 6 passes through the sliding groove 11.1 and is engaged and fixed on the toothed seat 12. The toothed plate 6 can disengage from the toothed seat 12 under the action of external force. Specifically, the toothed plate 6 includes a hinge part 6.1 and a meshing part 6.2. The meshing part 6.2 is provided in the movable gap 13, and the width of the meshing part 6.2 is smaller than the movable gap. The hinge 6.1 passes through the slide groove 11.1 and is fixedly connected to the meshing part 6.2. The meshing part 6.2 can slide along the slide groove 11.1 through the hinge 6.1 within the movable gap 13. The fixed end of the side support cylinder 2 is hinged to the hinge 6.1. When the hinge 6.1 is subjected to an outward force, since the width of the meshing part 6.2 is less than the width of the movable gap 13, the meshing part 6.2 will disengage from the meshing state with the tooth seat 12. When the hinge 6.1 is subjected to an inward force, the meshing part 6.2 will move inward and mesh and fix with the tooth seat 12.

[0032] In practical use, the column 1 is placed vertically on the ground of the tunnel. Hydraulic oil is connected to the hydraulic pipe interface 1.4, and the telescopic end of the vertical support cylinder 1.2 extends. The upper end of the vertical support cylinder 1.2 begins to rise and abuts against the top surface of the mine. As the telescopic end of the vertical support cylinder 1.2 continues to extend, the claw seat 5 is pushed into the ground, thereby fixing the column 1 to the ground. The upper surface of the claw seat 5 is provided with reinforcing ribs 5.1, and the bottom surface of the claw seat 5 is also provided with multiple anti-slip teeth 5.2 to enhance the stability between the claw seat 5 and the ground. At this time, the movable beam 3 remains perpendicular to the top beam 4 under the action of gravity, and the telescopic end of the control side support cylinder 2 extends. Please refer to the appendix. Figure 4 As shown, the movable beam 3 rotates upward along the hinge point with the top beam 4 under the action of the side support cylinder 2. During the rotation of the movable beam 3, when the movable beam limiting hole 3.1 on the movable beam 3 aligns with the top beam limiting hole 4.1 on the top beam 4, the side support cylinder 2 stops extending and inserts the limiting pin 7 into the movable beam limiting hole 3.1 and the top beam limiting hole 4.1, thereby fixing the movable beam 3 onto the top beam 4. At this time, the telescopic end of the side support cylinder 2 is controlled to extend and retract inward. Please refer to the appendix. Figure 5 and attached Figure 7As shown, during the inward extension and retraction of the control side support cylinder 2, a pulling force is applied to the toothed plate 6, causing the meshing part 6.2 of the toothed plate 6 to disengage from the tooth seat 12. At this time, the hinge part 6.1 of the toothed plate 6 moves upward along the slide groove 11.1 under the pulling force of the side support cylinder 2. When the hinge part 6.1 of the toothed plate 6 reaches the top of the slide groove 11.1, the extension and retraction end of the control side support cylinder 2 is extended outward again. At this time, the side support cylinder 2 applies an inward pushing force to the meshing part 6.2, and the meshing part 6.2 re-engages and is fixed on the tooth seat 12. Finally... Remove the limiting pin 7, and the movable beam 3 continues to rotate upward under the push of the side support cylinder 2 and abuts against the top surface of the roadway. The side support cylinder 2 then supports the movable beam 3, thereby achieving the purpose of supporting the top surface of the mine. Since this invention is an integral support device and the support process is simple and easy to operate, it can achieve the effect of one side being excavated and the other side being supported during the mine tunneling process. Excavation and support can be carried out simultaneously, overcoming the drawback of the traditional support method that requires stopping the excavation process, and greatly improving the tunneling efficiency.

[0033] In the above embodiment, as a preferred embodiment, the protective cover 1.1 is designed with a square structure. The sliding plate 11, the toothed seat 12, and the top beam 4 are all fixed on one side wall of the protective cover 1.1. To enhance the strength of the entire device, two toothed plates 6 are provided. Two toothed seats 12 corresponding to the two toothed plates 6 are provided in the movable gap 13. A first fixed shaft 14 is provided between the two toothed plates 6. Correspondingly, the side support cylinders 2 are set as two side support cylinders. The fixed ends of the two side support cylinders 2 are respectively hinged to the ends of the first fixed shaft 14. At the same time, the movable beams 3 are also set as two movable beams. A second fixed shaft 15 is provided between the two movable beams 3. The telescopic ends of the two side support cylinders 2 are respectively hinged to the ends of the second fixed shaft 15. Two top beams 4 are fixed on the protective cover 1.1. A third fixed shaft 16 is provided between the two top beams 4. The two movable beams 3 are respectively hinged to the ends of the third fixed shaft 16. Through the above scheme, the support strength of the entire device can be enhanced, and the support effect of the entire device can be improved.

[0034] The embodiments described above are merely illustrative of specific implementations of the present invention, and while the descriptions are detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
