[0002] Medium-deep hole drilling and blasting is one of the commonly used mining methods in metal and non-metal mines. Among them, deep hole drilling and blasting has become a widely used ore extraction technology due to its lower cost and higher efficiency.

[0003] In the process of mining using deep-hole drilling and blasting, from the start of deep-hole construction in the ore chamber until blasting, in order to prevent the borehole opening from collapsing or other debris such as rocks from falling into the hole and affecting the normal progress of drilling and subsequent deep-hole blasting, a rolled-up iron casing needs to be installed at the blasting hole opening during construction. The casing is then retrieved during deep-hole blasting.

[0004] Traditionally, sheet metal tubes are made by manually hammering and mechanically rolling, which is time-consuming and labor-intensive. The work is carried out underground, involving hot work, and the emission of welding fumes and pollutants is difficult, posing high safety risks and complicated approval procedures.

[0031] Figure 1 This is a front view of the deep hole orifice iron tube winding device according to an embodiment of the present utility model; Figure 2 This is a side view of the deep hole orifice iron tube winding device according to an embodiment of the present utility model.

[0032] like Figure 1 and Figure 2 As shown in the figure, the deep hole opening sheet metal tube winding device provided by this utility model mainly includes a base 1, a drive shaft 2 and two driven shafts 3.

[0033] The base 1 includes a fixed plate 11 and a bottom plate 12 connected to the fixed plate, which can fix the drive shaft 2 and the driven shaft 3 between the two fixed plates 11. The drive shaft 2 and the driven shaft 3 are arranged in a triangle between the fixed plates 11, and the two driven shafts 3 are arranged parallel to each other above the bottom plate 12. The drive shaft 2 is located above the driven shaft 3. The sheet metal to be rolled enters through the gap between the drive shaft 2 and the driven shaft 3 and is rolled upward into a sheet metal tube, which is convenient for workers to remove the formed sheet metal tube.

[0034] A crank handle 4 is provided at one end of the drive shaft 2, which can drive the drive shaft 2 to rotate; a vertical downward adjustment groove 5 is provided on the top of the fixed plate 11, and a pre-tightening device 6 is provided in the adjustment groove 5. The pre-tightening device 6 is used to adjust the width of the gap between the drive shaft 2 and the driven shaft 3, which can adapt to iron sheets of different thicknesses to be rolled.

[0035] In one specific embodiment of this utility model, the base plate 12 is a rectangular steel plate or is connected by steel pipes, which can firmly connect the two fixing plates 11 together and fix the drive shaft 2 and the driven shaft 3 between the two fixing plates 11; and the base plate 12 does not affect the operation of the drive shaft 2 and the driven shaft 3; the fixing plate 11 has a structure that is narrow at the top and wide at the bottom, which can adapt to the triangular structure of the drive shaft 2 and the driven shaft 3, saving raw materials and having an aesthetically pleasing appearance, and can also prevent sharp corners from scratching workers and improve construction safety.

[0036] In one specific embodiment of this utility model, both the drive shaft 2 and the driven shaft 3 include a hollow shaft body and a rotating shaft fixedly connected to the hollow shaft body. The hollow shaft body can reduce the overall weight of the device and facilitate movement. Both ends of the rotating shaft extend out of the hollow shaft body and are movably connected to the fixing plate 11. A rotating hole 7 is provided on the fixing plate 11, and both ends of the rotating shaft of the driven shaft 3 pass through the rotating hole 7. The two ends of the rotating shaft can also be fixed with baffles to prevent the rotating shaft from coming out of the rotating hole 7. In addition, the hollow shaft body and the rotating shaft of the driven shaft 3 can also be movably connected, fixing the rotating shaft to the fixing plate 11, and the hollow shaft body can rotate around the rotating shaft. The rotating shaft of the drive shaft 2 passes through the adjusting groove 5. The width of the adjusting groove 5 is slightly larger than the outer diameter of the rotating shaft of the drive shaft 2, so that the drive shaft 2 can rotate freely without deviation, thus avoiding affecting the production quality.

[0037] In one specific embodiment of this utility model, the length and outer diameter of the hollow shafts of the drive shaft 2 and the driven shaft 3 are equal, and both can be made from scrap drill rods, which can ensure that the iron tube is formed regularly and save costs; the crank handle 4 is fixedly connected to the rotating shaft of the drive shaft 2, and cranking the crank handle 4 drives the hollow shaft of the drive shaft 2 to rotate, and under the friction of the iron sheet to be rolled, the driven shaft 3 is rotated.

[0038] In one specific embodiment of this utility model, the pre-tightening device 6 includes a support plate 61 and a pre-tightening bolt 62. The support plate 61 is used to support and fix the pre-tightening bolt 62. The support plate 61 is horizontally arranged on the top of the fixing plate 11 and welded to the fixing plate 11. A threaded adjustment hole 63 is provided on the support plate 61. The threaded adjustment hole 63 is located at the center of the adjustment groove 5. The pre-tightening bolt 62 is vertically downward and threadedly connected to the support plate 61 through the threaded adjustment hole 63. The bottom end of the pre-tightening bolt 62 abuts against the rotating shaft of the drive shaft 2 to adjust the width of the gap between the drive shaft 2 and the driven shaft 3 to accommodate iron sheets of different thicknesses to be rolled. A nut can also be provided on the threaded adjustment hole 63 to increase the thread length and make the connection between the pre-tightening bolt 62 and the support plate 61 more stable.

[0039] In one specific embodiment of this utility model, the pre-tightening bolt 62 is a T-bolt, which is convenient for workers to rotate. A clamping block 64 is fixedly provided at the bottom of the pre-tightening bolt 62, which can increase the contact surface between the bottom end of the pre-tightening bolt 62 and the rotating shaft of the drive shaft 2, and prevent the rotating shaft of the drive shaft 2 from sliding out from the bottom end of the pre-tightening bolt 62 during use. Pre-tightening devices 6 are provided on both fixing plates 11 to keep the width of the gap at both ends consistent.

[0040] As can be seen from the above technical solution, the deep hole orifice iron tube winding device provided by this utility model has a reasonable structure, is easy to operate, and is made of scrap drill rods and scrap iron parts, resulting in low cost. Using this device, the work site can be moved to the surface, effectively avoiding underground hot work, solving the problem of welding fume pollution, and improving construction safety.
