Description

Technical Field

[0001] This utility model relates to the field of ventilation duct fabric docking technology, specifically to a quick docking device for ventilation duct fabric in iron ore mining roadways. Background Technology

[0002] In iron ore mining, to ensure the stable use of ventilation duct cloth, it is necessary to quickly connect multiple sections of ventilation duct cloth. For example, patent document CN220469997U discloses a dust isolation type ventilation duct cloth for mining. When connecting the ventilation duct cloth, a set of ventilation duct connecting rings with a large cross-section are set at the end of the ventilation duct. The outer wall of the ventilation duct connecting rings is opened with a spacing of clamping secondary grooves and clamping main grooves. In this way, when it is necessary to extend the length of the ventilation duct and connect the ventilation duct connecting rings at the ends of the two sets of ventilation ducts, the ventilation duct edge cloths at the ends of the two sets of ventilation ducts can be combined with the clamping secondary grooves or clamping main grooves of the opposite ventilation ducts, thereby achieving the purpose of extending the ventilation duct channel. Moreover, the double-layer ventilation duct edge cloth coverage enhances the sealing performance at the connection of the two sets of ventilation ducts, and the construction is simpler and saves more time. Furthermore, the outside of the connected ventilation duct connecting rings can be covered with a ring-shaped collar gasket and locked with a locking rope, thereby improving the strength of the ventilation duct connection and the sealing strength.

[0003] When the above-mentioned duct cloth is connected, it is only connected by rotating and snapping between multiple clamping slots. However, when the duct cloth is large in volume, it is not convenient to rotate the duct cloth during the connection process, which reduces the convenience and efficiency of connection.

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] This utility model discloses a quick-connection device for ventilation duct cloth in iron ore mining roadways.

[0018] This utility model provides, for example Figure 1-3 The device shown is a quick-connection device for ventilation duct cloth in iron ore mining roadways. It includes ventilation duct cloth 1 and head ring 2 and tail ring 3 fixedly sleeved at both ends of ventilation duct cloth 1. The outer wall of the head ring 2 has a rotating groove 4. The inner wall of the rotating groove 4 is fixedly provided with multiple fixed frames 5 evenly distributed in the axial direction. The inside of the fixed frame 5 is rotatably connected to a rotating shaft 6. The shaft wall of the rotating shaft 6 is fixedly sleeved with a clamping plate 7. The tail ring 3 is sleeved with the rotating groove 4. The inner wall of the tail ring 3 is fixedly embedded with a sealing ring 17 and has an annular groove 8. The end of the clamping plate 7 is engaged with the inside of the annular groove 8. The shaft wall of the rotating shaft 6 is sleeved with a torsion spring 9. The two ends of the torsion spring 9 are fixedly connected to the rotating shaft 6 and the fixed frame 5, respectively.

[0019] In order to enable the quick disassembly and separation of two adjacent ventilation duct fabrics, such as Figure 2-3 As shown, a pull-and-separate mechanism for pulling the clamping plate 7 is provided between the head ring 2 and the clamping plate 7. The pull-and-separate mechanism includes a pull plate 10. The outer wall of the head ring 2 has multiple axially evenly distributed moving grooves. A guide block 11 slides through the moving groove. A spring 12 is fixed between the guide block 11 and the inner wall of the moving groove. One end of the pull plate 10 is hinged to the outer wall of the guide block 11. The lower end of the clamping plate 7 has a groove. A support rod 13 is fixed in the groove. The upper end of the pull plate 10 is rotatably engaged with the support rod 13. A rotating ring 14 is rotatably sleeved on the outer wall of the head ring 2. A limiting bolt 16 is threaded between the rotating ring 14 and the head ring 2. Multiple push rods 15 are fixed on the outer wall of the rotating ring 14. The push rods 15 are U-shaped rods. The ends of the push rods 15 are engaged with the guide block 11. A guide groove is provided on the side of the guide block 11.

[0020] Working principle: When using, if two sections of duct cloth 1 need to be connected, first align the tail ring 3 at the end of one section of duct cloth 1 with the rotating groove 4 of the head ring 2 at the end of the other section of duct cloth 1, and push the tail ring 3 to gradually insert it into the rotating groove 4. During the insertion process, the outer wall of the tail ring 3 will contact the end of the clamping plate 7 and generate pressure, causing the clamping plate 7 to rotate around the rotating shaft 6 in the fixed frame 5. At this time, the torsion spring 9 sleeved on the shaft wall of the rotating shaft 6 is twisted and stored. When the tail ring 3 is fully inserted into the rotating groove 4 and the annular groove 8 on the tail ring 3 is aligned with the end of the clamping plate 7, the torsion spring 9 releases the stored force, drives the rotating shaft 6 to rotate in the opposite direction, and then pushes the end of the clamping plate 7 into the annular groove 8. Through the clamping and engagement of multiple axially evenly distributed clamping plates 7 and annular groove 8, the two sections of duct cloth 1 are quickly connected. At the same time, the sealing ring 17 fixedly embedded in the inner wall of the tail ring 3 is tightly fitted with the inner wall of the head ring 2 to ensure the sealing of the connection and prevent air leakage. To separate the two sections of the duct cloth 1, first loosen the limiting bolt 16 between the rotating ring 14 and the head ring 2, rotate the rotating ring 14, and the rotating ring 14 will drive the multiple U-shaped push rods 15 fixed on the outer wall to rotate synchronously. After the end of the push rod 15 contacts the guide groove on the side of the guide block 11, as the rotating ring 14 continues to rotate, the push rod 15 pushes the guide block 11 to slide in the moving groove of the head ring 2 along the guide groove. The guide block 11 squeezes the spring 12 on the inner wall of the moving groove to make it contract. When the guide block 11 slides, it pulls the support rod 13 at the lower end of the clamping plate 7 through the pull plate 10 that is hinged to it, causing the clamping plate 7 to rotate around the rotating shaft 6 and disengage from the annular groove 8. After all the clamping plates 7 have disengaged from the annular groove 8, the two sections of the duct cloth 1 can be pulled to pull the tail ring 3 out of the rotating groove 4, thus completing the separation. After separation, loosen the rotating ring 14, the spring 12 releases its stored force to push the guide block 11 to reset, the pull plate 10 drives the clamping plate 7 to return to the initial position, and then tighten the limit bolt 16 to fix the rotating ring 14 for the next docking.

[0021] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
