Description

Technical Field

[0001] The utility model belongs to the technical field of mining blasting equipment, in particular to an open-air deep hole blasting water pressure spacer. Background Art

[0002] In the process of mining or exploration of various ores, blasting is often required. In order to facilitate blasting work, a large number of blasting equipment are used. Among them, spacers are a common blasting equipment. They are used to reduce the consumption of explosives, reduce shock and water, reduce the foundation, and reduce the explosion pressure in the blast hole, etc.

[0003] The existing document with the publication number CN214120955U discloses a lifting-type disc air spacer, including an upper disc, a lower disc, a support tube, a hanging ring, a traction rope, and a fixed ejection device. The support tube is fixedly connected between the upper disc and the lower disc, and a plurality of fixed ejection devices are arranged on the upper surface of the upper disc. The center of the upper disc is connected to the hanging ring, and the traction rope is connected to the hanging ring. The fixed ejection device includes two adjacently arranged cylinders, one end of the cylinder is closed and the other end is open. The cylinder is arranged radially along the upper disc, and its open end faces outward. A vertical groove is arranged in the middle of the cylinder. A lifting rod is clamped in the vertical grooves of the two cylinders. A compressed spring is arranged in the cylinder on one side of the lifting rod. The outer end of the spring is connected to the chuck. The center of the chuck is fixedly connected to the excitation needle. The middle of the lifting rod is connected to the lifting rope.

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. The air spacer mentioned above has a support tube fixedly connected between the upper disc and the lower disc, and the support tube is composed of a soft cover body and an elastic spiral steel wire, wherein the elastic spiral steel wire is located on the outside of the soft cover body. The setting of the elastic spiral steel wire facilitates the axial stretching of the soft cover body, but the presence of the elastic spiral steel wire also limits the circumferential stretching of the soft cover body, making it inconvenient to fill the entire blast hole, and is not suitable for blast holes of different apertures, and its applicability is poor;

[0006] 2. The fixed ejection device of the air spacer mentioned above is composed of a cylinder, a lifting rod, a spring and an excitation needle. The lifting rod and the spring drive the excitation needle to move, and the spacer is fixed by the excitation needle. However, since the power of the excitation needle mainly comes from the elastic restoring force of the spring, it is not convenient to insert the excitation needle into the inner wall of the borehole with higher hardness, and it is not convenient to fix the spacer in the boreholes with different hardness.

[0007] To this end, we provide an open-air deep hole blasting water pressure spacer to solve the above-mentioned problems. Utility Model Content

[0008] The utility model aims to provide a water pressure spacer for open-air deep hole blasting. Water is added to the interior of an elastic bag through a water inlet pipe in an auxiliary component to expand the elastic bag, so that the outer side of the elastic bag is tightly fitted on the inner wall of the blast hole, thereby solving the existing problem that it is inconvenient to fill blast holes of different sizes. A sleeve rod is driven to rotate by a motor in a fixed component, and under the action of a threaded connection between the sleeve rod and the inner rod, the arc plate drives the spike to move toward the inner wall of the blast hole, thereby solving the existing problem that it is inconvenient to fix inside blast holes of different hardnesses.

[0009] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0010] The utility model is a water pressure spacer for open-air deep hole blasting, comprising a cylinder, an auxiliary component is arranged on the outside of the cylinder, and a fixing component is also arranged on the bottom of the cylinder.
