Description

Technical Field

[0001] The utility model belongs to the field of coal mine production, and particularly relates to a device for encapsulating yellow mud in deep-hole blast holes. Background Art

[0002] The blast-hole blasting method is a commonly used method in rock excavation. It involves drilling a certain number of blast holes in the rock, then loading an appropriate amount of explosive and plugging it, and finally detonating it. When plugging the explosive, yellow mud is needed for plugging. In the prior art, when using yellow mud for plugging, a pressed yellow mud column is filled by hand, resulting in the problem that the filling is not firm, which in turn affects the detonation effect. Content of the Utility Model

[0003] The purpose of the utility model is to provide a device for encapsulating yellow mud in deep-hole blast holes to solve the problem that the hand-filled yellow mud column is not firm, which in turn affects the detonation effect.

[0004] The utility model adopts the following technical solutions: A device for encapsulating yellow mud in deep-hole blast holes, comprising:

[0005] A mud loading cylinder filled with a yellow mud column, which is used to be inserted into the blast hole together with the yellow mud column, and continuously withdrawn from the blast hole after the yellow mud column enters the blast hole, so that the yellow mud column plugs the blast hole; A fixing ring is sleeved on the outer end of the mud loading cylinder, and the inner edge of the fixing ring is integrally connected with the outer wall of the mud loading cylinder and is coaxially arranged with the mud loading cylinder;

[0006] An extrusion mechanism for extruding the yellow mud column in the mud loading cylinder so that the yellow mud column leaves the mud loading cylinder and is inserted into the blast hole;

[0007] The extrusion mechanism includes: a limit ring, an extrusion plate, a connecting rod, and a hydraulic cylinder; The limit ring is arranged close to the fixing ring and is connected to the fixing ring through a flange; The extrusion plate is located outside the mud loading cylinder and is used to extend into the inner cavity of the mud loading cylinder filled with yellow mud, and continuously extrude the yellow mud column so that the yellow mud column leaves the mud loading cylinder and is inserted into the blast hole; The inner end of the connecting rod is fixedly connected to the extrusion plate, and its outer end extends outward and is used to push the extrusion plate to extrude the yellow mud column through it; The piston rod of the hydraulic cylinder is fixed on the outside of the limit ring and is used to push the connecting rod to move into the inner cavity of the mud loading cylinder, thereby extruding the yellow mud column to leave the mud loading cylinder and enter the blast hole.

[0008] Further, it further includes:

[0009] A connecting plate, which is fixedly connected to the outer end of the connecting rod and the fixed end of the hydraulic cylinder respectively, and is used to drive the connecting rod to move into the inner cavity of the mud loading cylinder under the drive of the hydraulic cylinder.

[0010] Further, two hydraulic cylinders are provided and are symmetrically arranged, and the connecting plate is fixedly connected to the fixed ends of the two hydraulic cylinders respectively.

[0011] The beneficial effects of the present utility model are as follows:

[0012] The present utility model can greatly improve the density of the filled yellow mud column. By setting a hydraulic cylinder to drive a connecting plate, the connecting plate pushes a connecting rod, and then squeezes an extrusion plate, so that the extrusion plate squeezes the yellow mud column and forces the yellow mud column to leave the mud loading cylinder and enter the blast hole. During the movement of the hydraulic cylinder, by applying an external force manually to pull the mud loading cylinder outward from the blast hole, then as the mud loading cylinder withdraws from the blast hole outward, the yellow mud column enters the blast hole, making the encapsulated yellow mud dense and firm.

[0017] The present utility model discloses a device for encapsulating yellow mud in deep blast holes, as Figure 1 shown, including: a mud loading cylinder 10, a fixed ring 11, and an extrusion mechanism.

[0018] The mud loading tube 10 is a cylindrical structure with openings at both ends. The mud loading tube 10 is filled with yellow mud columns. The outer end opening of the mud loading tube 10 is used to load the yellow mud columns, and the inner end opening is used for the yellow mud columns to escape from the inner cavity of the mud loading tube 10 and enter the blasthole. The mud loading tube 10 is used to be inserted into the blasthole together with the yellow mud columns, and continuously withdraw from the blasthole after the yellow mud columns enter the blasthole, so that the yellow mud columns seal the blasthole.

[0019] The fixing ring 11 is sleeved on the outer end of the mud tube 10, and the inner edge of the fixing ring 11 is integrally connected with the outer wall of the mud tube 10, and the fixing ring 11 is coaxially arranged with the mud tube 10. The squeezing mechanism is used to squeeze the yellow mud column in the mud tube 10 so that the yellow mud column leaves the mud tube 10 and is inserted into the blasthole.

[0020] The extrusion mechanism includes: a limiting ring 12 , an extrusion plate 13 , a connecting rod 14 , and a hydraulic cylinder 15 .

[0021] The limiting ring 12 is arranged close to the fixing ring 11 and is connected to the fixing ring 11 through a flange; the extrusion plate 13 is located on the outside of the mud filling tube 10, and the extrusion plate 13 is used to extend into the inner cavity of the mud filling tube 10 filled with yellow mud, and continuously squeeze the yellow mud column so that the yellow mud column leaves the mud filling tube 10 and is inserted into the blasthole.

[0022] The inner end of the connecting rod 14 is fixedly connected to the extrusion plate 13, and the outer end of the connecting rod 14 extends outward and is used to push the extrusion plate 13 to extrude the yellow mud column; the piston rod of the hydraulic cylinder 15 is fixed on the outside of the limit ring 12, and the hydraulic cylinder 15 is used to push the connecting rod 14 to move toward the inner cavity of the mud loading barrel 10, thereby squeezing the yellow mud column out of the mud loading barrel 10 and entering the blasthole.

[0023] The utility model further comprises: a connecting plate 16, which is fixedly connected to the outer end of the connecting rod 14 and the fixed end of the hydraulic cylinder 15 respectively, and the connecting plate 16 is used to drive the connecting rod 14 to move toward the inner cavity of the mud loading barrel 10 under the drive of the hydraulic cylinder 15.

[0024] Preferably, two hydraulic cylinders 15 are provided and are symmetrically arranged, and the connecting plate 16 is fixedly connected to the fixed ends of the two hydraulic cylinders 15 respectively.

[0025] The utility model can greatly improve the density of the filled yellow mud column, and drives the connecting plate 16 by arranging the hydraulic oil cylinder 15, so that the connecting plate 16 pushes the connecting rod 14, and then squeezes the squeezing plate 13, so that the squeezing plate 13 squeezes the yellow mud column, and forces the yellow mud column to leave the mud filling tube 10 and enter the blasthole. During the movement of the hydraulic oil cylinder 15, the mud filling tube 10 is pulled to move outside the blasthole by external force, and then the yellow mud column enters the blasthole while the mud filling tube 10 withdraws outward from the blasthole, so that the encapsulated yellow mud is dense and firm.

[0026] In the prior art, it usually takes 1 hour to seal holes per shift. After using the present utility model, it only takes 0.5 hours to seal holes per shift, greatly shortening the deep hole blasting operation time of the fully mechanized mining face and improving the production efficiency.
