Technical Field

[0001] The present invention relates to the technical field of blast hole filling, and specifically relates to a fixed-distance installation mechanism for explosives in mine blast holes. Background Art

[0002] When filling multiple explosive tubes in mine blast holes, sand and gravel need to be backfilled between adjacent groups of explosive tubes. Since the blast holes are underground and invisible, it is impossible to ensure the depth of the backfilled sand and gravel, so the distance between the two groups of explosive tubes cannot be determined, and the blasting is not accurate enough.

Detailed Embodiment

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0022] As Figure 1 , Figure 2 and Figure 3 shown, a fixed-distance installation mechanism for explosive charges in mine blast holes includes a column body 100. Two groups of cavities 110 and loading tubes 120 are provided inside the column body 100, and the two groups of cavities 110 are distributed around the outside of the loading tube 120;

[0023] Inside the cavity 110, a counterweight 140 is inserted. Inside the loading tube 120, a bearing bottom plate 130 is inserted. A connecting rope 150 is connected between the bearing bottom plate 130 and the counterweight 140. When the bearing bottom plate 130 descends, it drives the counterweight 140 to rise equidistantly.

[0024] Above the counterweight 140, a measuring rod 170 is connected. The rising height of the measuring rod 170 is equal to the descending height of the bearing bottom plate 130.

[0025] In the above, before measurement, the counterweight 140 is placed on the bottom wall of the cavity 110, and then the cylinder 100 is inserted into the blasting hole. After the explosive tube is placed on the surface of the bearing bottom plate 130 and pressed down, when the upper end surface of the explosive tube is flush with the upper end surface of the cylinder 100, record the initial height M of the measuring rod 170. Set the distance N between two groups of explosive tubes. Press down the explosive tube and backfill sand and gravel into the loading tube 120. Observe the height of the measuring rod 170. When the height of the measuring rod 170 reaches M + N, at this time, the second group of explosive tubes can be placed and pressed down until it is flush with the upper end surface of the cylinder 100, and record the height M of the measuring rod 170 again. Repeat the above steps to perform fixed-distance filling of the explosive tubes.

[0026] The surface of the measuring rod 170 is provided with scale values.

[0027] Through the above design, the operator can directly read the value on the surface of the measuring rod 170, thereby shortening the installation time of the explosive tube.

[0028] As Figure 4 shown, the two groups of cavities 110 are connected through a slideway 111, and the two groups of counterweights 140 are connected through a slide bar 141. When the slide bar 141 rises, it slides along the track of the slideway 111.

[0029] Through the above design, the two groups of counterweights 140 are connected, and in cooperation with the sliding of the slide bar 141 inside the slideway 111, the stability of the counterweight 140 when rising is ensured.

[0030] On the upper surface of the cylinder 100, a fixed pulley 160 is connected, and the connecting rope 150 bypasses the surface of the fixed pulley 160.

[0031] Through the above design, it is avoided that the connecting rope 150 directly contacts the upper end surface of the cylinder 100, and the friction between the connecting rope 150 and the cylinder 100 is reduced.

[0032] On the side wall of the bearing bottom plate 130, a slider 131 is connected. On the side wall of the loading tube 120, a chute 121 for the slider 131 to slide is opened, and the slider 131 slides inside the chute 121.

[0033] Through the above design, the slider 131 can slide inside the chute 121, thereby avoiding the inclination of the bearing bottom plate 130 when it descends and ensuring the stability of the bearing bottom plate 130 when it descends.

[0034] A measuring ring 180 is sleeved outside the measuring rod 170, and a bolt 190 is threadedly connected inside the measuring ring 180, and the bolt 190 abuts against the measuring rod 170.

[0035] Through the above design, the measuring ring 180 is fixed at the initial value M, and the value M can be continuously recorded.

[0036] A plug rod 161 is connected to the bottom of the fixed pulley 160, and a hole for inserting the plug rod 161 is provided inside the column 100.

[0037] Through the above design, the operator can conveniently disassemble the fixed pulley 160 for multiple uses.

[0038] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention. Any reference signs in the claims should not be regarded as limiting the claims involved.
