Description

Technical Field

[0001] The utility model relates to the technical field of column safety valve protection, in particular to an anti-collapse device for a column safety valve. Background Art

[0002] The column safety valve is a key component of the hydraulic support column. When the support is subjected to impact ground pressure or the pressure reaches a safe value, the safety valve will automatically open the valve to unload the pressure inside the column, thereby achieving the purpose of protecting the column.

[0003] During the use of the support, due to the complex underground conditions, the column safety valve is easily damaged by flying stones or coal blocks, and anti-collapse measures are particularly important. If anti-collapse measures cannot be effectively taken, the equipment will need to be frequently shut down for maintenance, which will indirectly lead to an increased probability of equipment damage and a gradual reduction in lifespan. To this end, we propose an anti-collapse device for the column safety valve to solve the above problems. Utility Model Content

[0022] See also Figure 1-4In the present invention, a collapse prevention device for a column safety valve comprises a protection box 3, on the outer surface of which two groups of first springs 2 and two groups of second springs 13 are fixedly mounted, one end of each group of first springs 2 is fixedly mounted with a first collapse prevention plate 17, one end of each group of second springs 13 is fixedly mounted with a second collapse prevention plate 18, and on the outer surface of the protection box 3 two groups of first dampers 9 and two groups of second dampers 14 are fixedly mounted, one end of each group of first dampers 9 is fixedly mounted with the inner wall of the first collapse prevention plate 17, and one end of each group of second dampers 14 is fixedly mounted with the inner wall of the second collapse prevention plate 18. The column safety valve can be placed inside the protection box 3, each group of first springs 2 and each group of first dampers 9 connect the first anti-collapse plate 17 and the protection box 3, and the first anti-collapse plate 17 can prevent flying gangue or coal blocks from directly hitting the protection box 3, each group of second springs 13 and each group of second dampers 14 connect the second anti-collapse plate 18 and the protection box 3, and the second anti-collapse plate 18 can prevent flying gangue or coal blocks from directly hitting the protection box 3, the two groups of first dampers 9 and the two groups of second dampers 14 can respectively limit the two first anti-collapse plates 17 and the two second anti-collapse plates 18.

[0023] The outer surface of each first anti-collapse plate 17 is fixedly installed with a first protective pad 4, and the outer surface of each second anti-collapse plate 18 is fixedly installed with a second protective pad 10. Each first protective pad 4 can protect the outer surface of the first anti-collapse plate 17, and can effectively prevent splashing gangue or coal blocks from directly hitting the first anti-collapse plate 17 to produce a loud noise. Each second protective pad 10 can protect the outer surface of the second anti-collapse plate 18, and can effectively prevent splashing gangue or coal blocks from directly hitting the second anti-collapse plate 18 to produce a loud noise. The outer surface of the protective box 3 is hinged with a protective cover 6 through a hinge 12. A first circular hole 15 is provided on the upper surface of the protective cover 6. The protective cover 6 can be flipped freely, so that the column safety valve can be conveniently placed inside the protective box 3. The protective cover 6 can protect the top of the column safety valve. By providing a first circular hole 15 on the upper surface of the protective cover 6, it is convenient to connect the pipeline to the top of the column safety valve.

[0024] The outer surface of the protection box 3 is fixedly installed with a buckle 8, and the outer surface of the protection cover 6 is fixedly installed with a handle 7. The buckle 8 is fastened to the handle 7. Through the fastening of the buckle 8 and the handle 7, the protection box 3 and the protection cover 6 can better protect the column safety valve. Three mounting blocks 11 are fixedly installed on the outer surface of the protection box 3. A mounting hole 1 is opened on the upper surface of each mounting block 11. By installing three mounting blocks 11 on the outer surface of the protection box 3 and opening a mounting hole 1 on the upper surface of each mounting block 11, the device can be firmly installed underground after a bolt is passed through the mounting hole 1. A protection tube 5 is fixedly installed on the upper surface of the protection cover 6, and a second circular hole 16 is opened on the bottom surface of the protection box 3. By installing the protection tube 5 on the upper surface of the protection cover 6, the connection between the column safety valve and the pipeline can be effectively protected. By opening a second circular hole 16 on the bottom surface of the protection box 3, the pipeline below can be conveniently connected to the bottom end of the column safety valve.

[0025] The working principle of this utility model is:

[0026] When gangue or coal blocks splash, the first protective pad 4 or the second protective pad 10 will provide protection for the outer surface of the first anti-collapse plate 17 or the second anti-collapse plate 18. When the gangue or coal blocks splash and the fragments are large, the first anti-collapse plate 17 or the second anti-collapse plate 18 will squeeze the first spring 2 or the second spring 13 after being hit. When the first spring 2 is squeezed and deformed, the two first dampers 9 can shrink. When the second spring 13 is squeezed and deformed, the two second dampers 14 can shrink. When the collision is over, the two first dampers 9 can drive the first anti-collapse plate 17 to return to its initial position, and the two second dampers 14 can drive the second anti-collapse plate 18 to return to its initial position.

[0027] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
