Description

Technical Field

[0001] The utility model relates to the technical field of deep hole pre-splitting blasting, in particular to an anti-dumping positioning instrument for medium-deep hole pre-splitting blasting. Background Art

[0002] Medium-deep hole pre-splitting blasting is a commonly used blasting method in mining. It involves drilling medium-deep holes at equal intervals above the rock formation to be blasted. Connecting wires are then placed between each blasthole, and explosive cartridges and fuses are installed inside the blastholes. This method is characterized by its simple structure, ease of use, and ease of implementation. It can minimize damage to the rock slopes that need to be preserved, effectively improving work efficiency and safety. The explosive cartridges are lowered and loaded using a shaped casing and connecting sleeve, and are assembled section by section.

[0003] At present, in the process of charging, due to the deep pre-crack hole, the explosive roll will be lowered by connecting the energy-gathering sleeve and the connecting sleeve, which will increase the direction of the energy-gathering sleeve, resulting in unstable blasting effect. In addition, during blasting, the shock wave generated by the blasting causes the explosives to tilt or fall during the blasting process, which reduces the blasting accuracy and poor blasting effect. Utility Model Content

[0008] Preferably, a mounting plate is fixedly connected to the side wall of the clamping box, a fixing screw is meshedly connected to the mounting plate, and the clamping block is fitted in the limiting groove.

[0009] Preferably, the two ends of the No. 1 spring are respectively fixedly connected to the side wall of the mounting block and the inner wall of the chassis, and the two ends of the No. 2 spring are respectively fixedly connected to the side wall of the extrusion block and the inner wall of the chassis.

[0010] Preferably, both ends of the No. 3 spring are respectively connected to the inner side walls of the connecting blocks on both sides.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. By installing the limiting mechanism into the limiting groove, the slider squeezes the supporting device to increase the distance between the supporting devices. At this time, the No. 1 spring is compressed, and the No. 1 spring generates an inward force on the mounting block. The mounting block drives the supporting device through the connecting rod to generate an inward force so that the supporting device clamps and fixes the limiting mechanism, further limiting the energy-gathering casing. At the same time, the fixing mechanism and the supporting device are inserted into the pre-cracked hole. The No. 2 spring is in an extended state, and the No. 2 spring generates an outward force on the extrusion block. The extrusion block drives the guide rod to squeeze the fixed block, so that the fixed block squeezes the inner wall of the pre-cracked hole, thereby avoiding the energy-gathering casing from tilting or tipping during the blasting process, thereby further improving the blasting effect.

[0013] 2. By installing the energy-gathering sleeve between the arc-shaped plates and engaging the energy-gathering grooves with each other, the direction of the energy-gathering sleeve is controlled by the energy-gathering grooves, thereby avoiding the direction of the energy-gathering sleeve from changing when the sleeve is placed in the pre-crack hole, thereby improving the accuracy of blasting.

[0014] 3. Pull the handle to engage the clamping block with the limit groove. At this time, the No. 3 spring is in a stretched state. The No. 3 spring generates a pulling force on the connecting blocks on both sides, which in turn causes the clamping block to generate a pulling force on the upper part of the supporting equipment, thereby strengthening the clamping and fixing effect of the limit mechanism. At the same time, the fixing screw is fixed on the outer wall of the pre-crack hole to further prevent the energy-gathering casing from tilting or tipping over, thereby improving the accuracy and effect of blasting.
