Technical Field

[0001] This utility model relates to the field of blasting technology, and in particular to blasting auxiliary tools. Background Technology

[0002] When carrying out blasting operations, it is necessary to pre-drill blasting holes at the blasting location. Since a single blasting operation requires the arrangement of many blasting holes, the total drilling time is long. The pre-drilled blasting holes are exposed for a long time, and sand and rainwater may enter them, affecting the subsequent loading of explosives and causing the final blasting effect to deviate from the expected result. To solve this problem, it is necessary to use auxiliary tools to seal the surface of the blasting holes. Traditional sealing tools are not easy to install and have poor applicability. More suitable auxiliary tools are needed. Therefore, a blasting auxiliary tool was designed. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in related technologies. Therefore, one objective of this utility model is to provide a blasting auxiliary tool that is easy to assemble and disassemble and has strong applicability.

[0004] The blasting auxiliary tool proposed according to this utility model includes a box body and a sealing cover. An upper cover and a lower cover are fixed to the top and bottom of the box body, respectively. An upper limit plate is fixed to the lower surface of the upper cover, and an upper limit plate is fixed to the upper surface of the lower cover. A guide plate is provided inside the box body. Multiple guide rods are fitted between the upper limit plate, the lower limit plate, and the guide plate. A guide plate is fixed to the surface of each guide rod. A positioning arc plate is fixed to one end of the guide plate extending outside the box body. A transmission rod is provided at the center of the guide plate. The transmission rod passes through the guide plate, the upper limit plate, the upper cover, and the sealing cover. Limit rods are symmetrically fixed to the upper surface of the upper cover on both sides of the transmission rod. A pusher is threadedly connected to the top of each limit rod. A rotating rod is threaded through the middle of the pusher, and the bottom of the rotating rod is fixed to the top of the transmission rod.

[0006] Preferably, the guide plate has a threaded hole at its center, and a through hole at the bottom of the threaded hole. The bottom of the transmission rod has stepped threads and reverse threads. The threaded portion of the transmission rod is connected to the threaded hole of the guide plate, and the reverse threaded portion of the transmission rod passes through the through hole of the guide plate. A reverse threaded nut is threaded onto the reverse threaded portion extending out of the through hole.

[0007] Preferably, a handrail is symmetrically fixed to the upper surface of the sealing cap, a telescopic rod is fixed to the upper surface of the sealing cap, a flashlight is fixed to the top of the telescopic rod, and a soft pad is fixed to the lower surface of the sealing cap.

[0009] Preferably, pin holes are vertically and equidistantly opened on the surface of the limiting rod, and a U-shaped piece is inserted between the limiting rods.

[0010] The beneficial effects of this utility model are:

[0011] 1. This auxiliary tool is easy to install. The operation steps are divided into five hand actions: holding the hand tube, pressing the pusher, rotating the turntable, pushing the hand tube, and inserting the U-shaped tube. This completes the installation of the auxiliary tool on the surface of the blast hole to seal the blast hole. When disassembling, simply remove the U-shaped tube and then rotate the turntable in the opposite direction to remove the auxiliary tool. The whole process is easy to disassemble and assemble.

[0012] 2. This auxiliary tool is highly versatile. It is equipped with an upper limit plate, a lower limit plate, and a guide plate that work together to move the guide rod linearly. The guide rod drives the guide plate and the positioning arc plate to move synchronously, thereby adjusting the position of the positioning arc plate. This allows the auxiliary tool to be used for blasting holes of different diameters within a certain range. During assembly, if the positioning effect is poor on the first attempt, it may be due to damage to the inner wall of the blasting hole at that depth. The positioning position can be adjusted by pushing and pulling the pusher to adapt to the inner wall of the blasting hole. It has strong assembly applicability. Attached Figure Description

The overall rotation angle of the guide plate 7 is less than 60°. Multiple guide rods 8 are fitted between the upper limit plate 5, the lower limit plate 6 and the guide plate 7. A guide plate 9 is fixed on the surface of the guide rod 8. The end of the guide plate 9 extending out of the box 1 is fixed with a positioning arc plate 10. The outer surface of the positioning arc plate 10 is provided with a protrusion, which generates greater friction when in contact with the inner wall of the blast hole. A transmission rod 11 is provided at the center of the guide plate 7. The transmission rod 11 passes through the guide plate 7, the upper limit plate 5, the upper cover 3 and the sealing cover 2. Limiting rods 12 are symmetrically fixed on the upper surface of the upper cover 3 and on both sides of the transmission rod 11. The top of the limiting rods 12 are threadedly connected to a pusher 13. A rotating rod 14 is provided through the middle of the pusher 13. The bottom of the rotating rod 14 is fixed to the top of the transmission rod 11. A turntable 15 is threadedly connected to the top of the rotating rod 14.

[0019] A bearing 16 is fixed to the outer ring surface of the guide plate 7, and a sleeve 17 is fixed to the outer ring surface of the bearing 16. The outer ring surface of the sleeve 17 is provided with multiple protrusions in a circular array. The inner side wall of the box body 1 is provided with multiple docking grooves in a circular array. The protrusions dock with the docking grooves. The outer surface of the box body 1 is provided with multiple side through grooves in a circular array for the movement of the guide plate 9. With the above structure, the guide plate 7 can be quickly installed into the box body 1.

[0020] A threaded hole is provided at the center of the guide plate 7, and a through hole is provided at the bottom of the threaded hole. The bottom of the transmission rod 11 has stepped distribution of forward and reverse threads. The forward threaded part of the transmission rod 11 is connected to the threaded hole of the guide plate 7, and the reverse threaded part of the transmission rod 11 passes through the through hole of the guide plate 7. A reverse threaded nut is installed on the reverse threaded part extending out of the through hole. The forward and reverse threaded nuts are used to position the transmission rod 11 from two rotation directions to prevent the transmission rod 11 from loosening when the auxiliary tool is in use.

[0021] A handrail is symmetrically fixed to the upper surface of the sealing cover 2. A telescopic rod is fixed to the upper surface of the sealing cover 2. A flashlight is fixed to the top of the telescopic rod. The flashlight allows workers to quickly identify the position of the auxiliary tool. A soft pad 18 is fixed to the lower surface of the sealing cover 2. The soft pad 18 is elastic and can better fit the blast hole.
