Description

Technical Field

[0001] The utility model relates to the technical field of blasting, in particular to a blasting charge loading device for underground metal mine mining. Background Art

[0002] In medium and deep hole blasting in metal mines, drilling operations are usually carried out on a pre-built bench. The drilling is generally divided into two forms: vertical drilling and inclined drilling. The drilling rig drills holes at pre-planned fixed points. The drilled holes are usually called blast holes. Then, explosive packages are placed in the qualified blast holes. In the charging process of the explosive package in the vertical blast hole, an explosive package with a detonating circuit is usually placed at the bottom of the blast hole, and then other explosive packages without circuits are stacked in sequence. The explosive packages fall in the blast hole by their own gravity.

[0003] Due to the rough inner wall of the blast hole, the explosive package is prone to skew during the falling process of charging, resulting in the problem of explosive package blockage. Currently, the method of inserting a blasting rod into the blast hole to push the explosive package down is often used for dredging. However, the blasting rod needs to be taken out after each dredging, and the work efficiency is low. Content of the Utility Model

[0004] In view of this, the purpose of the utility model is to provide a blasting charge loading device for underground metal mine mining to solve the problem that after the explosive package is blocked in the prior art, it is necessary to insert a blasting rod into the blast hole to push the explosive package down for dredging, but the blasting rod needs to be taken out after each dredging, and the work efficiency is low.

[0005] The utility model is realized through the following technical solutions:

[0006] A blasting charge loading device for underground metal mine mining includes a first vertical plate and a second vertical plate. The bottoms of the first vertical plate and the second vertical plate are respectively hinged with a first support plate and a second support plate. A locking component is installed between the first support plate and the second support plate. The second support plate can be connected to the first support plate under the action of the locking component.

[0007] Further, the locking component includes a bolt. A limiting hole adapted to the bolt is provided on the first support plate. A through hole adapted to the bolt is provided on the second support plate. The bolt is slidably connected in the through hole. A traction component is installed at one end of the bolt away from the first support plate. The traction component can pull the bolt out of the limiting hole.

[0008] Further, the traction component includes a traction rope. One end of the traction rope is fixedly connected to the bolt, and the other end extends outwards to the top of the second vertical plate.

[0009] Further, an elastic support component is installed in the through hole. In the natural stretching state of the elastic support component, the bolt can protrude from one end of the through hole away from the traction rope under the action of the elastic support component.

[0010] Further, the through hole is stepped, the elastic support assembly includes a spring, two ends of the spring respectively abut against the side wall of the through hole and the side wall of the plug pin. When the spring is in a natural extended state, the plug pin can protrude from the end of the through hole away from the towing rope under the action of the spring.

[0011] Further, a groove is formed on one side of the through hole close to the towing rope, the groove communicates with the through hole, and a connecting rod is installed between the plug pin and the towing rope. One end of the connecting rod is movably connected to the plug pin, and the other end is fixedly connected to the towing rope.

[0012] Further, a mounting plate is installed on the tops of the first vertical plate and the second vertical plate. A strip-shaped hole adapted to the cross-sections of the first vertical plate and the second vertical plate is formed on the mounting plate. The first vertical plate and the second vertical plate are slidably connected in the strip-shaped hole. First limit plates and second limit plates are respectively fixedly connected to the tops of the first vertical plate and the second vertical plate, and both the first limit plate and the second limit plate are located on the upper surface of the mounting plate.

[0013] Further, a plurality of ground cones are fixedly connected to the bottom surface of the mounting plate, and the plurality of ground cones are evenly distributed on both sides of the limit plate.

[0014] Further, a threaded hole is formed in the side wall of the first vertical plate, and a screw rod is inserted into the threaded hole. One end of the screw rod is rotatably connected to the second vertical plate.

[0015] Further, a card slot is formed in the inner side wall of the first vertical plate, and the card slot extends along the length direction of the first vertical plate.

[0016] The beneficial effects of the utility model are as follows:

[0017] For the underground metal mine blasting charge loading device, the first support plate and the second support plate are connected together through the locking assembly. Then, the bottoms of the first vertical plate and the second vertical plate are placed into the blast hole, and then the first vertical plate and the second vertical plate are moved in opposite directions to increase the relative distance between the first vertical plate and the second vertical plate.
