DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] like Figure 1 and Figure 2 As shown, this embodiment provides an embodiment of a digital electronic detonator zone line quick twisting device. In this embodiment, the twisting device includes a through pipe 1 for passing through the zone line. A rotating tube 2 is provided at one end of the through pipe 1. The zone line passes through the through pipe 1 and enters the rotating tube 2. The position of the zone line is fixed after passing through. A rotating disk 11 is fixedly connected to one end of the through pipe 1 close to the rotating tube 2. A rotating ring 21 is rotatably connected to the outer side of the rotating disk 11. The rotating ring 21 is fixedly connected to one end of the rotating tube 2, so that the rotating tube 2 can keep rotating in place under the action of the rotating disk 11 and the rotating ring 21, thereby realizing the twisting of the zone line.

[0023] Among them, the first fixing component 3 and the second fixing component 4 are used to compress and fix the zone line before twisting. The first fixing component 3 includes a fixing box 31 fixedly connected to one side of the through pipe 1, and the second fixing component 4 is installed on the rotating tube 2.

[0024] Further, see Figure 3 , driving the area line in the rotating tube 2 to rotate to realize the twisting mechanism 5, the twisting mechanism 5 includes a rotating rod 51, a first hand wheel 52, a gear 53, and a gear ring 54. The rotating rod 51 is rotatably connected to the side of the fixed box 31 close to the rotating tube 2, and the rotating rod 51 keeps rotating in place. The first hand wheel 52 is installed at one end of the rotating rod 51 close to the rotating tube 2, and the setting of the first hand wheel 52 facilitates the rotation of the rotating rod 51. The rotating rod 51 is also fixedly connected with a gear 53, and the rotating rod 51 drives the gear 53 to rotate synchronously when rotating. The outer ring sleeve of the rotating ring 21 is installed with a gear ring 54, and the gear ring 54 rotates synchronously with the rotating ring 21. The gear 53 is meshed with the gear ring 54, and the gear 53 drives the gear ring 54 to rotate synchronously when rotating.

[0025] Further, see Figure 4The first fixing assembly 3 also includes a first threaded rod 32, a second hand wheel 33, a threaded sleeve 34, a connecting frame 35, and a clamping block 36. The first threaded rod 32 is rotatably connected to the fixing box 31, and the first threaded rod 32 rotates in the original position. One end of the first threaded rod 32 passes through a side wall of the fixing box 31 and is fixedly connected to the second hand wheel 33. The second hand wheel 33 is arranged to facilitate the rotation of the first threaded rod 32. Two groups of threaded sleeves 34 are sleeved on the second hand wheel 33. The tops of the two groups of threaded sleeves 34 are fixedly connected to the connecting frame 35. The connecting frame 35 is an L-shaped structure and the two groups of connecting frames 35 are symmetrically arranged. The connecting frame 35 and the fixing box 31 are slidably matched, so that the connecting frame 35 moves smoothly. The ends of the two groups of connecting frames 35 that are close to each other are fixedly connected to the clamping block 36 that is slidably connected to the through pipe 1. When the threaded sleeve 34 moves, the clamping block 36 is driven to move synchronously through the connecting frame 35, so that the two groups of clamping blocks 36 can clamp and fix the area line in the through pipe 1 when they are close to each other.

[0026] Furthermore, the first fixing assembly 3 further includes a positioning block 37 rotatably connected to the middle position of the first threaded rod 32, and the positioning block 37 is fixedly connected to the inner wall of the fixing box 31, so that the position of the first threaded rod 32 is more stable. Two groups of threaded sleeves 34 are symmetrically arranged on both sides of the positioning block 37, and the first threaded rods 32 on both sides of the positioning block 37 have opposite thread directions. Both groups of threaded sleeves 34 are threadedly connected to the first threaded rod 32, so that when the first threaded rod 32 rotates, it can drive the two groups of first threaded rods 32 to move without rotating under the limiting action of the connecting frame 35, and at the same time, the movement directions of the two groups of threaded sleeves 34 are opposite.

[0027] Further, see Figure 5 The second fixing assembly 4 includes a pressing block 41, a limiting rod 42, a push plate 43, a limiting disk 44, and a spring 45. The pressing block 41 is slidably connected in the rotating tube 2, and the pressing block 41 presses the zone line in the rotating tube 2 after moving. A plurality of limiting rods 42 are fixedly connected to the side of the pressing block 41 away from the rotating tube 2, and the limiting rods 42 move synchronously with the pressing block 41. The plurality of limiting rods 42 are slidably connected to the push plates 43 together, and one end of each limiting rod 42 away from the pressing block 41 is fixedly connected to the limiting disk 44, and the limiting disk 44 is used for limiting to prevent the push plate 43 from detaching from the limiting rod 42. The outer ring of the limiting rod 42 is provided with a spring 45, and the spring 45 is arranged between the pressing block 41 and the push plate 43. The spring 45 releases its elastic force after being compressed, so that the pressing block 41 is pressed against the zone line to be compressed, and at the same time, it is prevented from being twisted due to excessive mechanical force.

[0028] Further, the second fixing assembly 4 further includes a second threaded rod 46, a knob 47, and a fixing plate 48. The second threaded rod 46 is rotatably connected to the side of the push plate 43 away from the rotating tube 2. The second threaded rod 46 drives the push plate 43 to move when moving, but the second threaded rod 46 does not drive the push plate 43 to rotate due to the limitation of the limiting rod 42 when rotating. The end of the second threaded rod 46 away from the push plate 43 is fixedly connected to the knob 47, and the setting of the knob 47 facilitates the rotation of the second threaded rod 46. The second threaded rod 46 is also threadedly connected to the fixing plate 48, and the fixing plate 48 is fixedly connected to the side of the rotating ring 21, so that the second threaded rod 46 can move along its own length direction when rotating.

[0029] Furthermore, the second fixing assembly 4 also includes a pressure pad 49 installed on the side of the pressure block 41 away from the limiting rod 42. The pressure pad 49 is made of rubber to prevent the area line from being squeezed too tightly. Excessive squeezing may cause the area line pressed in the rotating tube 2 to be unable to move when the rotating tube 2 rotates, thereby increasing the tension during rotation and causing breakage.

[0030] The utility model is provided with a first fixing assembly 3 and a second fixing assembly 4 in the through pipe 1 and the rotating pipe 2, respectively. The first fixing assembly 3 is used to clamp and fix the area line in the through pipe 1 firmly, and the second fixing assembly 4 is used to press the area line in the rotating pipe 2, and the twisting connection of the area line is realized when the rotating pipe 2 rotates, and the area line in the rotating pipe 2 slides toward the side of the through pipe 1 as the twisting connection is carried out. After the area line passes through the through pipe 1 and is inserted into the rotating pipe 2, the second hand wheel 33 is rotated and the first threaded rod 32 is driven to rotate, and at the same time, the first threaded rod 32 drives the two groups of threaded sleeves 34 to approach each other, and drives the two groups of clamping blocks 36 to approach each other through the connecting frame 35. After the two groups of clamping blocks 36 approach each other, the area line in the through pipe 1 is clamped and fixed. Then the knob 47 is rotated to make the second threaded rod 46 rotate, and at the same time, the second threaded rod 46 drives the push plate 43 to approach the side of the rotating pipe 2. At the same time, due to the setting of the spring 45, the pressing block 41 slides in the rotating pipe 2 and presses the area line, and at the same time, the pressing pad 49 contacts the area line. When the push plate 43 continues to move, the spring 45 is compressed, and the elastic force of the spring 45 causes the pressure pad 49 to press the zone line tightly. At the same time, when the zone line is subjected to tension, it can move along the length direction of the rotating tube 2. Finally, the first hand wheel 52 is turned, and the first hand wheel 52 drives the rotating rod 51 to rotate, so that the gear 53 rotates and engages with the gear ring 54. At this time, the rotating tube 2 starts to rotate, so that the zone line is twisted from the position between the first fixing component 3 and the second fixing component 4 to achieve twisting. At the same time, since the first fixing component 3 is rigid in fixing the zone line, as the zone line is twisted, the part of the zone line pressed by the pressure pad 49 can slide, thereby preventing the zone line from breaking due to increased tension. After the twisting is finally completed, the knob 47 is loosened, and the second hand wheel 33 is turned to make the two groups of clamps 36 move away from each other, so as to facilitate the extraction of the zone line after the twisting.

[0031] The above detailed description of the specific implementation of the utility model is only used as an example, and the utility model is not limited to the specific implementation described above. For those skilled in the art, any equivalent modification or substitution of the utility model is also within the scope of the utility model. Therefore, the equalization, modification, improvement, etc. made without departing from the spirit and principle of the utility model should be included in the scope of the utility model.
