Description
Technical Field
[0001] The utility model relates to the technical field of explosive hole charging, in particular to an explosive charging structure in an engineering blasting water hole. Background Technique
[0002] The application of engineering blasting in engineering is undoubtedly the most important and common. In mining and mountain opening, drill and blast methods are used to excavate tunnels for railways and highways, and it is also used in some water conservancy projects. Among engineering blasting, underwater blasting is a common blasting method.
[0003] For underwater blasting, explosives need to be placed in water. When existing charging equipment is used, explosives are generally directly inserted, making it easy for the explosives to come into contact with sundries in the external water. Furthermore, under the extrusion of the blasting hole, the waterproof layer of the explosives is damaged, which will affect the progress of underwater blasting. Therefore, it is necessary to propose an explosive charging structure in an engineering blasting water hole. Summary of the Utility Model
[0004] The utility model aims to at least solve one of the technical problems in the related technologies to some extent. For this reason, an object of the utility model is to propose an explosive charging structure in an engineering blasting water hole. The packaged explosives are inserted into the storage groove above the rubber pad, and then the positioning cone is inserted into the blasting hole to prevent sundries in the water from entering the blasting hole. At the same time, the blasting hole is aligned with the notch of the storage groove, and then the lifting block is driven to move and push the explosives to move. The explosives will squeeze the rubber pad and expand the opening in the middle, so that the explosives are pushed and enter the blasting hole, so that the explosives can avoid being damaged by extrusion with sundries in the water during the loading process.
[0005] According to the explosive charging structure in an engineering blasting water hole proposed by the utility model, it includes a fixed rod. A positioning cone is fixedly connected to the lower end of the fixed rod. A storage groove is jointly opened on the fixed rod and the positioning cone. A moving groove is opened on the groove wall of the storage groove. A threaded rod is rotatably connected between the groove walls of the moving groove through a bearing. A threaded sleeve is threadedly connected to the rod wall of the threaded rod. A moving block is fixedly sleeved on the outer side wall of the threaded sleeve. One end of the moving block penetrates and extends into the storage groove and is fixedly connected to a lifting block. An annular rubber pad is fixedly connected at the notch of the storage groove.
[0006] Preferably, a support ring is fixedly sleeved on the outer rod wall of the fixed rod near the bottom end.
[0007] Preferably, two hand-held handles are fixedly connected to the outer rod wall of the fixed rod near the top end.
[0008] Preferably, the upper end of the threaded rod extends through the fixed rod, and a rotating handle is fixedly connected to one end of the threaded rod outside the fixed rod.
[0009] Preferably, the moving block is slidably connected in the moving groove, and the lifting block is slidably connected in the receiving groove.
[0010] The beneficial effects of the present utility model are as follows: First, insert the packaged explosive into the receiving groove above the rubber pad, then insert the positioning cone into the blasting hole to prevent debris in the water from entering the blasting hole. At the same time, align the blasting hole with the notch of the receiving groove, and then rotate the threaded rod to drive the lifting block to move and push the explosive. The explosive will squeeze the rubber pad and expand the opening in the middle, so that the explosive is pushed and enters the blasting hole, avoiding damage caused by squeezing with debris in the water during the loading process of the explosive.

[0015] Refer to Figures 1-3 , the blasting charge structure in the engineering blasting water hole includes a fixed rod 1. A positioning cone 2 is fixedly connected to the lower end of the fixed rod 1. A receiving groove 3 is jointly opened on the fixed rod 1 and the positioning cone 2. A moving groove 4 is opened on the groove wall of the receiving groove 3. A threaded rod 5 is rotatably connected between the groove walls of the moving groove 4 through a bearing. A threaded sleeve 6 is threadedly connected to the rod wall of the threaded rod 5. A moving block 7 is fixedly sleeved on the outer side wall of the threaded sleeve 6. One end of the moving block 7 extends through the receiving groove 3 and is fixedly connected to a lifting block 8. An annular rubber pad 9 is fixedly connected to the notch of the receiving groove 3.
[0016] Among them, a support ring 10 is fixedly sleeved on the outer rod wall of the fixed rod 1 near the bottom end. By abutting the support ring 10 against the outer wall of the position where the blasting hole is located, when the fixed rod 1 enters the blasting hole, it will cause large-scale expansion of the blasting hole and affect the fixation of the explosive.
[0017] Among them, two hand-held handles 11 are fixedly connected to the outer rod wall of the fixed rod 1 near the top end. The fixed rod 1 can be moved by holding the hand-held handles 11, and the positioning cone 2 can be inserted into the blasting hole.
[0018] Among them, the upper end of the threaded rod 5 penetrates and extends outside the fixed rod 1, and a rotating handle 12 is fixedly connected to one end of the threaded rod 5 located outside the fixed rod 1. The threaded rod 5 can be rotated by rotating the rotating handle 12.
[0019] Among them, the moving block 7 is slidably connected in the moving groove 4, and the lifting block 8 is slidably connected in the storage groove 3, so that the moving block 7 and the lifting block 8 can only move parallelly.
[0020] When the device is used, first insert the packaged explosive into the middle hole of the rubber pad 9 and expand it, then insert it into the storage groove 3 above the rubber pad 9 along the hole. At this time, the rubber pad 9 supports the explosive to store it in the storage groove 3. After that, when charging is required, first clean the blasting hole, then the positioning cone 2 can be inserted into the blasting hole to prevent sundries in the water from entering the blasting hole. Then rotate the threaded rod 5 by rotating the rotating handle 12. The threaded rod 5 drives the moving block 7 to move in the moving groove 4 through the cooperation with the threaded sleeve 6, and the moving block 7 will drive the lifting block 8 to move synchronously and push the explosive, so that the explosive is inserted into the middle hole of the rubber pad 9 and expands it, and then enters the blasting hole along the hole and the notch of the storage groove 3, making the loading of the explosive relatively simple and convenient and avoiding damage caused by extrusion with sundries in the water.
