[0005] The principle of the utility model is that when in use, the silk thread is passed under the guide roller and under the pressure wheel, and then the screw is manually rotated, the screw rotates and the screw barrel makes a threaded motion, thereby causing the screw barrel to move downward, and then the screw barrel drives the wheel seat to move downward, and the wheel seat drives the pressure wheel to move, pressing the silk thread against the ground, so that during the movement of the device for wire release, the silk thread is limited to prevent the device from moving and causing the silk thread to move, and then the device is moved, and the motor is started, the motor drives the support roller to rotate, and the support roller rotates to release the silk thread, during this process, the spring acts on the square plate, so that the square plate is pressed down, and then the square rod is pressed down, so that the square rod drives the mounting seat to move downward, and then the guide roller is pressed down, so that the silk thread is tensioned during the wire release process, and the silk thread is prevented from loosening.

[0006] The beneficial effect of the utility model is that the spring acts on the square plate, so that the square rod drives the mounting seat to move downward, thereby pressing the guide roller downward, thereby tensioning the wire during the wire-releasing process, and preventing the wire from loosening.

[0007] By rotating the screw rod and the screw barrel to make a threaded motion, the wheel seat drives the pressure wheel to move, pressing the wire tightly on the ground, so that the wire is limited during the movement of the device to prevent the wire from moving due to the movement of the device.

[0008] Furthermore, the tensioning mechanism includes a slide plate, a dovetail block, a square tube, a square rod, a square plate, a spring, a sliding pin, a mounting seat, and a guide roller.

[0020] like Figure 1 As shown, this embodiment provides a device for drilling positioning and laying out wires in blasting operations, including a base 1, a support 2 is welded to the upper end of the base 1, a support roller 3 is arranged inside the support 2, a motor 4 is arranged at the front end of the support 2, the output end of the motor 4 passes through the support 2 and is rotatably connected to the support 2, the output end is fixedly connected to the support roller 3, a wire 5 is arranged on the outer side of the support roller 3, a tensioning mechanism 6 is arranged on the base 1, a frame 7 is welded to the upper end of the base 1, and a wire pressing mechanism 8 is arranged on the frame 7.

[0021] like Figure 1 , Figure 2 , Figure 3 As shown, the tensioning mechanism 6 includes a slide plate 61, a dovetail block 62, a square tube 63, a square rod 64, a square plate 65, a spring 66, a sliding pin 67, a mounting seat 68, and a guide roller 69. The upper end of the base 1 is slidably connected with the slide plate 61, and the lower end of the slide plate 61 is welded with a dovetail block 62. The dovetail block 62 and the base 1 are slidably connected. By setting the dovetail block 62, the movement of the slide plate 61 is guided. The upper end of the slide plate 61 is welded with a square tube 63, and the inside of the square tube 63 is slidably connected with the square rod 64. The lower end of the square rod 64 is welded with a square plate 65, and the square plate 65 and the square tube 63 are slidably connected. The outer side of the square rod 64 is provided with a spring 66. The spring 66 One end is welded to the square plate 65, and the other end of the spring 66 is welded to the square tube 63. By setting the spring 66, the square plate 65 is elastically pressed down, and a sliding pin 67 is welded to the edge of the square plate 65. The sliding pin 67 and the square tube 63 are slidably connected. By setting the sliding pin 67, the movement of the square plate 65 is guided. A mounting seat 68 is welded to the upper end of the square rod 64, and a guide roller 69 is arranged in the mounting seat 68. The guide roller 69 is in contact with the wire 5. The spring 66 acts on the square plate 65, so that the square rod 64 drives the mounting seat 68 to move downward, thereby pressing the guide roller 69 downward, and thereby tensioning the wire 5 during the wire-releasing process to prevent the wire 5 from loosening.

[0022] like Figure 1 , Figure 4 As shown, the wire pressing mechanism 8 includes a screw 81, a screw barrel 82, a wheel seat 83, a pressure wheel 84, and a guide rod 85. The screw 81 is installed inside the frame 7 through a bearing, and the screw barrel 82 is connected to the outside of the screw 81 through a thread. The lower end of the screw barrel 82 is welded with a wheel seat 83, and the inside of the wheel seat 83 is provided with a pressure wheel 84. The upper end of the wheel seat 83 is welded with a guide rod 85. The guide rod 85 and the frame 7 are slidably connected. By setting the guide rod 85, the movement of the wheel seat 83 is guided. By rotating the screw 81 and the screw barrel 82 to make a threaded movement, the wheel seat 83 drives the pressure wheel 84 to move, and the wire 5 is pressed against the ground. In the process of moving the device to release the wire, the wire 5 is limited to avoid the movement of the device causing the wire 5 to move.

[0023] The specific implementation process of the utility model is as follows: when in use, the wire 5 is passed under the guide roller 69 and under the pressure wheel 84, and then the screw rod 81 is manually rotated. The screw rod 81 rotates and the screw barrel 82 makes a threaded motion, thereby causing the screw barrel 82 to move downward, thereby causing the screw barrel 82 to drive the wheel seat 83 to move downward, and the wheel seat 83 drives the pressure wheel 84 to move, pressing the wire 5 against the ground, so that during the movement and release of the device, the wire 5 is limited to prevent the device from moving and causing the wire 5 to move, and then the device is moved, and the motor 4 is started. The motor 4 drives the support roller 3 to rotate, and the support roller 3 rotates to release the wire 5. During this process, the spring 66 acts on the square plate 65, so that the square plate 65 is pressed down, and then the square rod 64 is pressed down, so that the square rod 64 drives the mounting seat 68 to move downward, thereby causing the guide roller 69 to be pressed down, thereby causing the wire 5 to be tensioned during the release process to prevent the wire 5 from loosening.

[0024] The spring 66 acts on the square plate 65, so that the square rod 64 drives the mounting seat 68 to move downward, thereby pressing the guide roller 69 downward, and thus the wire 5 is tensioned during the wire-releasing process to prevent the wire 5 from loosening.

[0025] By rotating the screw rod 81 and the screw barrel 82 to make a threaded motion, the wheel seat 83 drives the pressure wheel 84 to move, pressing the wire 5 against the ground, so that the wire 5 is limited during the movement of the device to prevent the wire 5 from moving due to the movement of the device.
