Description

Technical Field

[0001] The utility model relates to the technical field of engineering blasting, in particular to a blasting tube protection structure. Background Art

[0002] Engineering blasting refers to the use of explosive energy to exert work on a medium to achieve a predetermined engineering goal. It is primarily used in large-scale projects such as railways, mines, and reservoirs. Examples include mountain tunneling during mining and road construction, and directional blasting for urban demolition. Existing engineering blasting tube protection structures typically incorporate a buffer structure to cushion the impact of blasting. However, this protection is not very effective and can cause the blasting tube to collide with the hole wall, damaging it. Therefore, we propose a blasting tube protection structure. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems in the related art to a certain extent. To this end, one object of the present invention is to provide a blasting tube protection structure to increase the protection effect of the blasting tube and prevent the blasting tube from being damaged.

[0004] According to the blasting tube protection structure proposed by the present invention, it includes a protection frame and a blasting tube body, and the upper and lower ends of the outer surface of the blasting tube body are provided with a plurality of first buffer plates distributed in a circle-centered array, the outer surfaces of the plurality of first buffer plates are fixedly connected to the first telescopic rod, one end of the plurality of first telescopic rods is fixedly connected to the second buffer plate, a first spring is fixedly connected between the plurality of second buffer plates and the first buffer plate, and the first spring is sleeved on the outer end of the first telescopic rod, the second telescopic rod is fixedly connected between the protection frame and the plurality of first buffer plates, and the second spring is fixedly connected between the protection frame and the plurality of first buffer plates, and the second spring is sleeved on the outer end of the second telescopic rod.

[0005] Preferably, the outer wall of the protection frame is provided with a plurality of arc-shaped grooves distributed in a circle-centered array, and the second buffer plates are all clamped in the arc-shaped grooves.

[0006] Preferably, a plurality of through holes are formed through the upper and lower end surfaces of the protective frame.

[0007] Preferably, the bottom of the protective frame is fixedly connected with a plurality of fixing nails.

[0008] Preferably, the inner diameter of the plurality of first buffer plates is adapted to the outer diameter of the blasting tube body.

[0009] The beneficial effect of the utility model is that when the blasting tube body is detonated, a part of the impact force of the blasting can be buffered by the arrangement of the first buffer plate, the second telescopic rod, the second spring, the protective frame, and the fixing nail, and then a part of the impact force can be further buffered by the action of the first telescopic rod, the first spring, the second buffer plate, and the through hole, thereby increasing the protective effect of the blasting tube and preventing the blasting tube from being damaged.

[0016] Reference Figure 1-5 The blasting tube protection structure includes a protection frame 1 and a blasting tube body 2. The upper and lower ends of the outer surface of the blasting tube body 2 are provided with several first buffer plates 21 distributed in a circle array. The outer surfaces of the several first buffer plates 21 are fixedly connected with the first telescopic rod 22, and one end of the several first telescopic rods 22 is fixedly connected with the second buffer plate 23. A first spring 24 is fixedly connected between the several second buffer plates 23 and the first buffer plate 21, and the first spring 24 is sleeved on the outer end of the first telescopic rod 22. The second telescopic rod 3 is fixedly connected between the protection frame 1 and the several first buffer plates 21. The second spring 31 is fixedly connected between the protection frame 1 and the several first buffer plates 21, and the second spring 31 is sleeved on the outer end of the second telescopic rod 3.

[0017] Furthermore, the outer wall of the protective frame 1 is provided with a plurality of arc grooves 11 distributed in a circle-centered array, and the second buffer plates 23 are all stuck in the arc grooves 11. The arc grooves 11 can accommodate the second buffer plates 23 and reduce the volume of the protective frame 1.

[0018] Furthermore, a plurality of through holes 12 are formed through the upper and lower end surfaces of the protective frame 1 , and the first telescopic rod 22 passes through the through holes 12 .

[0019] Furthermore, a plurality of fixing nails 13 are fixedly connected to the bottom of the protection frame 1 , and the protection frame 1 can be fixed in the hole through the plurality of fixing nails 13 .

[0020] Furthermore, the inner diameters of the plurality of first buffer plates 21 are adapted to the outer diameter of the blasting tube body 2 , and the impact force of the blasting tube body 2 will drive the first buffer plates 21 .

[0021] When the device is used, the protective frame 1 is first fixed in the hole by a number of fixing nails 13. When the blasting tube body 2 is detonated, the impact force will cause the first buffer plate 21 to be subjected to force to drive the second telescopic rod 3, thereby compressing the second spring 31. Under the buffering effect of the second spring 31, part of the impact force will be distributed on the protective frame 1. Then the first buffer plate 21 will drive the second buffer plate 23 to move outward through the first telescopic rod 22. When the second buffer plate 23 contacts the perforated wall, part of the impact force of the first buffer plate 21 will be distributed to the second buffer plate 23 under the action of the first spring 24, thereby increasing the protective effect when the blasting tube is exploded.
