Detailed Embodiment

[0018] Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] As Figures 1-3 shown, a roof-cutting energy-gathering pipe expansion fixing device mainly consists of an energy-gathering pipe body 1, three identical adjustable pressure fixing structures, and an installation support structure.

[0020] The adjustable pressure fixing structure mainly consists of a rotating hinge seat 2, a support rod 3, an installation groove 4, a fixed block 5, a sliding bracket 6, a sliding groove 7, a moving block 8, a compression spring 9, and a connecting support rod 10. Three identical adjustable pressure fixing structures are installed at the front end of the outer wall surface of the energy-gathering pipe body 1.

[0021] The rotary hinge base 2 is installed at the front end position of the outer wall surface of the shaped charge pipe body 1. One end of the support rod 3 is movably installed on the rotary hinge base 2. An installation groove 4 is opened at the other end of the support rod 3. The fixing block 5 is installed in the installation groove 4. The sliding bracket 6 is installed at the position behind the rotary hinge base 2. A sliding groove 7 is opened in the sliding bracket 6. The moving block 8 is embedded in the sliding groove 7. The compression spring 9 is installed inside the sliding groove 7 and its two ends are respectively installed on the inner wall surface of the sliding groove 7 and the moving block 8. The two ends of the connecting support rod 10 are respectively movably installed on the support rod 3 and the moving block 8.

[0022] Furthermore, the support rod 3 is installed on the rotary hinge base 2 through a pin shaft 11; the fixing block 5 is movably installed in the installation groove 4 through a connecting block 12; anti-slip teeth are opened on the fixing block 5; the two ends of the connecting support rod 10 are installed on the moving block 8 and the support rod 3 through connecting hinge seats 13.

[0023] The installation and support structure is installed at the rear end of the outer wall surface of the shaped charge pipe body 1. The installation and support structure is mainly composed of two pairs of installation blocks 14, two pairs of damping telescopic rods 15 and two pairs of support rollers 16.

[0024] Two pairs of installation blocks 14 are installed at the rear end position of the outer wall surface of the shaped charge pipe body 1. Two pairs of damping telescopic rods 15 are installed on the two pairs of installation blocks 14. Two pairs of support rollers 16 are installed on the output ends of the two pairs of damping telescopic rods 15.

[0025] The shaped charge pipe body 1 installs and supports the whole equipment. Insert the rear end of the shaped charge pipe body 1 into the blasting hole. Adjust the telescopic length of the damping telescopic rod 15 installed on the installation block 14 according to the aperture of the blasting hole, drive the support roller 16 installed at its output end to adjust the position, so that it can be attached and abutted against the inner wall of the blasting hole. Then press down the support rod 3 installed on the rotary hinge base 2 through the pin shaft 11. While pressing down, drive the connecting support rod 10 connected to it through the connecting hinge seat 13 to drive the moving block 8 to slide in the sliding groove 7 opened in the sliding bracket 6, so that the moving block 8 compresses the compression spring 9. After the pressing down is completed, continue to push the shaped charge pipe body 1 into the blasting hole. When it is completely pushed into the blasting hole, release it. Driven by the deformation elastic force of the compression spring 9, the support rod 3 rebounds outwards. The support rod 3 drives the fixing block 5 installed in the installation groove 4 opened on it through the connecting block 12 to abut against the inner wall of the blasting hole. The toothed structure of the fixing block 5 cooperates with the support roller 16 to stably support the shaped charge pipe body 1 and ensure the fixing effect.
