Description

Technical Field

[0001] This utility model relates to the field of blasting device technology, specifically a deep-hole blasting charge spacer. Background Technology

[0002] Spacers are typically used in blasting operations to separate the explosives loaded into the blast hole. This not only reduces explosive consumption but also facilitates control of blast energy, preventing excessive damage to the surrounding environment due to localized energy concentration. Currently, gas spacers are the most common type. However, gas spacers have relatively poor load-bearing capacity. As explosives are loaded into the blast hole, the gas spacer deforms under pressure, leading to errors in the explosive loading position. Furthermore, gas spacers require inflation, which demands high inflation stability. They are also significantly affected by extreme temperatures, resulting in shortcomings in their use.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 This utility model provides a technical solution: a deep-hole blasting charge spacer, including a spacer positioning component and a spacer support component. The spacer positioning component includes several telescopic positioning components 1, and two adjacent telescopic positioning components 1 are connected and fixed by a connecting cylinder 2. In use, an appropriate number of telescopic positioning components 1 are spliced ​​according to the requirements to meet the explosive spacing requirements in the blasting hole. Two sets of spacer support components are provided, and the two sets of spacer support components are respectively set at the upper and lower ends of the spacer positioning component. The spacer support component includes a positioning plate 4, which is also fixed to the end of the spacer positioning component by the connecting cylinder 2. The positioning plate 4 is used to increase the contact area between the telescopic positioning components 1 and the explosive and to stably support the explosive. The diameter of the positioning plate 4 is set according to the diameter of the blasting hole and can be adapted to the blasting hole.

[0019] The telescopic positioning component 1 includes a positioning cylinder 11 and a positioning rod 12. The positioning rod 12 is slidably disposed inside the positioning cylinder 11, and a fastening screw 13 for positioning the positioning rod 12 is provided on the upper side of the positioning cylinder 11. The length of the telescopic positioning component 1 is adjusted by sliding the positioning rod 12 inside the positioning cylinder 11 to meet the interval requirements. After adjusting the length of the telescopic positioning component 1, the fastening screw 13 is tightened to position the positioning rod 12 inside the positioning cylinder 11. The telescopic positioning component 1 uses a physical structure to support and position the explosive in the blast hole. Compared with the traditional gas spacer, it has higher structural support strength and is less affected by extreme external environmental temperatures. It also features quick adjustment, flexible splicing, and convenient use, and can be used immediately after installation.

[0020] A positioning post 14 is fixed at the end of the positioning rod 12 away from the positioning cylinder 11. The outer side of the positioning post 14 and the outer side of the positioning cylinder 11 are in contact with the inner side of the connecting cylinder 2. The positioning post 14 facilitates the splicing and fixing of two adjacent telescopic positioning parts 1 through the positioning cylinder 11.

[0021] Positioning holes are provided on the lower side of the positioning cylinder 11 and the side of the positioning post 14. An insertion hole is provided on the side of the connecting cylinder 2. A positioning pin 3 is provided in the insertion hole and is located in the positioning hole. The positioning pin 3 is engaged with the insertion hole and the positioning hole. The connecting cylinder 2 is placed at the splice of two adjacent telescopic positioning parts 1 and positioned by the positioning pin 3, which improves the connection stability and makes it easy to place this spacer in the blast hole for use.

[0022] A fixing post 5 is fixed on the side of the positioning plate 4. The outer side of the fixing post 5 contacts the inner side of the connecting cylinder 2. A limit hole is opened on the side of the fixing post 5. The limit hole is matched with the positioning pin 3 in the insertion hole. The setting of the fixing post 5 facilitates the connection and fixation of the positioning plate 4 and the telescopic positioning component 1. The connecting cylinder 2 is covered on the outside of the fixing post 5 and the bottom of the positioning cylinder 11 and fixed by the positioning pin 3, which facilitates the use of this spacer.
