Description

Technical Field

[0001] The utility model belongs to the technical field of blasting engineering, in particular to a blasting hole charging structure. Background Art

[0002] Blasting engineering refers to a construction method that uses explosives to excavate soil and stone, and demolish or destroy foundations, buildings, and structures. During the blasting operation, a drilling rig or rock drill is required to drill a suitable number of blasting holes at suitable locations in the rock and soil layers, and place a suitable amount of explosives in the blasting holes. When placing explosives in the blasting holes, a charging structure is usually used to charge the blasting holes to achieve better blasting results.

[0003] After retrieval, the authorization announcement number CN213021280U and the authorization announcement date 2021.04.20 disclose a combined charging structure for foundation pit blasting holes, including a positioning sleeve, a fixing plate is clamped between the upper and lower parts of the two clamps, a fixing rod is fixedly connected between the middle parts of the two fixing plates, an anchor nail is fixedly connected to the lower surface of the chassis, the other ends of the two connecting rods are hinged to each other, a spring is provided between the common hinge point of the two connecting rods and the slide groove away from the inner surface of the clamp, a positioning rod is fixedly connected to the upper surface of the slider, and a frame plate is provided on the upper surface of the positioning sleeve corresponding to the front and rear sides of the clamping plate, and a horizontal sleeve is fixedly connected to the upper part of the outer wall of the positioning sleeve, so that the explosives can be evenly and stably placed, the blasting effect is better, the explosives can be vertically inserted into the foundation pit, and the displacement of the position of the explosives can be prevented, so that the blasting accuracy is higher, and it is convenient to disassemble the positioning sleeve and fix the next foundation pit explosive.

[0004] The prior art requires real-time adjustment of the positioning tube during charging so that the rivet can be vertically inserted into the soil layer. During the adjustment process, the rivet is repeatedly tilted when the angle is adjusted, resulting in the hole being approximately trumpet-shaped when inserted into the soil layer. When the positioning tube is removed, the rivet is tilted due to the unstable connection between the rivet and the soil layer, resulting in the displacement of the explosive placement position, which reduces the accuracy of the blasting. In addition, the prior art is relatively laborious when inserting the rivet into the soil layer, which is inconvenient to use. For this reason, we provide a blasting hole charging structure to solve the above-mentioned problems. Utility Model Content

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a blast hole charging structure, comprising a charging device, wherein the charging device comprises a connecting rod, a plurality of placing boxes are axially fixed to the outer peripheral wall of the connecting rod, a mounting tube is arranged outside the placing box, a ring plate is fixed to the top of the mounting tube, a plurality of screw rods are arranged in an outer circumferential array of the mounting tube, an inner moving block is rotatably connected to the lower end of the screw rod through a bearing, an outer moving block is arranged outside the inner moving block, and a side plate is arranged outside the outer moving block;

[0009] The utility model is further configured that an end plate is fixed to the upper end of the connecting rod, and a plurality of insertion rods are fixed to a circumferential array on the lower wall of the placement box located at the lower end of the connecting rod.

[0010] The utility model is further configured as follows: the screw is threadedly connected to the annular plate, a top plate is fixed to the upper end of the screw, a screw block is fixed to the upper wall of the top plate, and a horizontal bubble is fixed to the upper wall of the annular plate.

[0011] The utility model is further configured such that the inner moving block and the outer moving block are both configured as isosceles triangles, and the inclined surface of the inner moving block contacts the inclined surface of the outer moving block, a connecting strip is fixed to the outer side wall of the outer moving block, and the outer end of the connecting strip is fixedly connected to the corresponding side panel.

[0012] The utility model is further configured such that the cross section of the connecting strip is rectangular, a boss is fixed to the outer peripheral wall of the mounting tube corresponding to the position of the outer moving block, a mounting plate is provided outside the connecting strip, and the mounting plate is L-shaped.

[0013] The utility model is further configured such that the connecting strip is gap-matched with the mounting plate, the inner end of the mounting plate is fixedly connected to the mounting tube, and the outer side wall of the side plate is arc-shaped.

[0014] The utility model is further configured such that the rotating plate is U-shaped, a protrusion is fixed to the inner side wall of the lower end of the rotating plate, a connecting plate is fixed to the outside of the protrusion corresponding to the upper wall of the annular plate, and the protrusion is rotatably connected to the connecting plate through a bearing, and a reinforcing plate is fixed to the upper end of the inner side wall of the rotating plate.
