Description

Technical Field

[0001] The utility model relates to the technical field of a truss device, and more specifically, to a truss device. Background Art

[0002] In the existing technology, the truss device used in the roof of the coal mine roadway faces a common problem during operation. Due to the particularity of the internal environment of the coal mine, a large amount of dust and coal slag often accumulates on the slide rails. This dust not only affects the smooth sliding of the slide rails, but also may have an adverse effect on the accuracy and stability of the truss device. However, the existing truss device is not equipped with an effective dust removal system, which makes it difficult to effectively solve the dust problem, thereby affecting the normal use and maintenance of the equipment.

This not only reduces the operating efficiency of the equipment, but also poses a potential risk to the safety of the coal mine tunnels. In addition, dust may enter the internal structure of the equipment, accelerate the wear of mechanical parts, and reduce the service life of the equipment. Utility Model Content

The pushing mechanism includes a threaded sleeve 13 and a thrust bearing 14. The threaded sleeve 13 is threadedly connected to the fixed sleeve 5, and the thrust bearing 14 is sleeved on the fixed sleeve 5, and the two ends of the thrust bearing 14 are respectively against the top rod 7 and the threaded sleeve 13. The fixed sleeve 5 is coaxially provided with a bottom sleeve 15, and the bottom sleeve 15 is provided with a spring 16. The fixed sleeve 5 is slidably provided with an unlocking sleeve 1 7. An unfastening sleeve 17 is connected to the spring 16. An unfastening groove 18 is provided on the unfastening sleeve 17. Unfastening rods 19 are provided on both sides of the middle plate 11. The unfastening groove 18 abuts against the unfastening rod 19. A plurality of push rods 20 are provided on the unfastening sleeve 17. The push rods 20 are supported on the thrust bearing 14.

The slider 2 is slidably connected to the slide rail 21.

[0030] In this embodiment, when it is necessary to connect the external blowing mechanism to the connecting pipe 3, the external pipe 6 is first inserted into the fixed sleeve 5. At this time, the threaded sleeve 13 is loosened to make the threaded sleeve 13 move upward. Therefore, under the action of the spring 16, the unwinding sleeve 17 is driven to move upward, and then the unwinding groove 18 is pressed against the unwinding rod 19, and then the push rod 7 is moved outward, so that the external pipe 6 can be directly inserted into the fixed sleeve 5. When the external pipe 6 is inserted into the fixed sleeve 5, the threaded sleeve 13 is rotated to first push out the unwinding sleeve 17 through the push rod 20, and at the same time, the thrust bearing 14 is also pressed on the push rod 7. Because the push rod 7 is inserted into the follow-up groove 10 under the action of the tension spring 12, and then the external connecting rod is pressed downward under the action of the threaded sleeve 13, thereby completing the sealing process. When it is necessary to unwind, it is only necessary to unwind the threaded sleeve 13 and the push rod 7 can be pushed out under the action of the spring 16, thereby completing the unwinding process.

[0031] More specifically, when the transverse frame 22 needs to be used, the slider 2 is installed on the transverse frame 22, and then the slider 2 is slidably connected to the slide rail 21. At the same time, gas is ejected through the dust blowing pipe 4 to blow away the dust on the slide rail 21, thereby avoiding the slider 2 from pressing on the slide rail 21, thereby improving the sliding effect and ensuring the stability of the truss.

[0032] In summary, when the overall equipment is in use or running: when it is necessary to connect the external blowing mechanism to the connecting pipe 3, first insert the external pipe 6 into the fixed sleeve 5, then loosen the threaded sleeve 13, so that the threaded sleeve 13 moves upward, so under the action of the spring 16, the unfastening sleeve 17 will be driven to move upward, and then the unfastening groove 18 will be pressed against the unfastening rod 19, and then the push rod 7 will be moved outward, so that the external pipe 6 can be directly inserted into the fixed sleeve 5. When the external pipe 6 is inserted into the fixed sleeve 5, the threaded sleeve 13 is rotated to first push out the unfastening sleeve 17 through the push rod 20, and at the same time, the thrust bearing 14 is also pressed on the push rod 7. Because the push rod 7 is inserted into the follow-up groove 10 under the action of the tension spring 12, and then the external connecting rod is pressed downward under the action of the threaded sleeve 13, thereby completing the sealing process. When it is necessary to unfasten, you only need to unfasten the threaded sleeve 13 and push the push rod 7 out under the action of the spring 16, thereby completing the unfastening process.

[0033] When the transverse frame 22 is needed, the slider 2 is installed on the transverse frame 22, and then the slider 2 is slidably connected to the slide rail 21. At the same time, gas is ejected through the dust blowing pipe 4 to blow away the dust on the slide rail 21, thereby avoiding the slider 2 from pressing on the slide rail 21, thereby improving the sliding effect and ensuring the stability of the truss.
