Description

Technical Field

[0001] The utility model relates to the technical field of engineering blasting, in particular to an explosive tube supporting device. Background Art

[0002] Blasting projects mainly involving tunnel, laneway and cave excavation construction usually do not purchase large-diameter explosives separately due to the small amount of deep-hole blasting work. Instead, small-diameter explosive tubes commonly used in tunnel blasting are used, and the small explosive rolls are bundled together with tape and ropes for use.

[0003] However, this method has many problems. On the one hand, the quality of bundling is difficult to guarantee. The bundling is not firm, which may cause the explosives to scatter during loading and become blocked, resulting in uneven distribution of explosives and affecting the blasting effect. It is also easy for the emulsion explosive tube to be damaged or the diameter of the explosive to be changed due to over-tight bundling, thus affecting the blasting effect. On the other hand, due to the bundling form, the amount of explosives may be insufficient. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example

[0030] like Figure 1-9 As shown, an explosive tube supporting device comprises a cylindrical explosive tube 1 and a supporting device for connecting several explosive tubes 1, the supporting device comprises a main tube 2 and a sub-tube 5, a shell 3 is arranged on the outer side of the main tube 2, an annular groove 31 is arranged between the shell 3 and the main tube 2, a charging bin Ⅰ21 is arranged inside the main tube 2, the charging bin Ⅰ21 penetrates the main tube 2, the explosive tube 1 is placed in the charging bin Ⅰ21, an insert piece 6 is arranged on the sub-tube 5, the insert piece 6 extends into the annular groove 31, a charging bin Ⅱ51 is arranged inside the sub-tube 5, the charging bin Ⅱ51 penetrates the sub-tube 5, when two explosive tubes 1 are connected, the explosive tubes 1 are respectively placed in the charging bin Ⅰ21 and the charging bin Ⅱ51, and the sub-tube 5 is tightly attached to the outer side of the shell 3.

[0031] like Figure 1 , 4As shown in Figures 5, 6, 7, 8, and 9, the inserting strip 6 includes a connecting plate 61 and an inserting plate 62. A slide groove 611 is provided inside the connecting plate 61. A slider 621 is provided at one end of the inserting plate 62. The inserting plate 62 is connected to the lower end of the connecting plate 61, and the slider 621 is slidably connected in the slide groove 611. Both ends of the slider 621 are raised. At the same time, the shape of the slide groove 611 is the same as that of the slider 621 to prevent the slider 621 from detaching from the slide groove 611. The inserting plate 62 can slide at the lower end of the connecting plate 61. 6 extends into the annular groove 31, and the inserting piece 6 and the annular groove 31 are respectively provided with mutually meshing tooth block assemblies, and the tooth block assembly includes tooth block I4 and tooth block II63. The tooth block I4 is arranged on the inner surface of the shell 3, and the tooth block I4 is arranged in an annular shape. The inserting piece 6 can extend into the annular groove 31 at different angles to connect a plurality of auxiliary pipes 5 and the main pipe 2. The tooth block II63 is arranged on the inserting plate 62. When the inserting piece 6 extends into the annular groove 31, the tooth block I4 and the tooth block II63 are meshed to prevent the auxiliary pipe 5 and the main pipe 2 from separating.

[0032] like Figure 7 , 8 As shown, there is interference fit between the explosive tube 1 and the charging bin Ⅰ21. When two explosive tubes 1 are to be connected, the auxiliary tube 5 is first placed on one side of the main tube 2, and the sliding plate 62 is moved away from the auxiliary tube 5. At this time, the insert plate 62 is inserted into the annular groove 31.

When the insert plate 62 is connected to the bottom of the annular groove 31, the explosive tube 1 is inserted into the charging bin Ⅰ21. The main tube 2 is made of elastic material. When the explosive tube 1 is inserted, the diameter of the main tube 2 becomes larger, so that the width of the annular groove 31 becomes smaller. At this time, the tooth block Ⅰ4 and the tooth block Ⅱ63 are directly meshed, and the auxiliary tube 5 and the main tube 2 are fixed. At this time, the explosive tube 1 is inserted into the charging bin Ⅱ51, and the two explosive tubes 1 are connected.
