Description

Technical Field

[0001] The present application relates to the technical field of auxiliary devices for filling emulsion explosives into blasting holes, and in particular to a deep-hole auxiliary explosive delivery device for a mixed emulsion explosive truck in an open-pit mine. Background Art

[0002] In the metal and non-metal open-pit mining industry, with the continuous development of mechanization, automation and intelligence, more and more open-pit mines are gradually popularizing the use of mechanical equipment to replace traditional manual charging at blasting construction sites. A field mixed emulsion explosive operation system with low manpower input, high degree of automation, stable construction efficiency, safe and reliable construction has also been rapidly promoted. However, the field mixed emulsion explosive operation system also has various differences in actual use due to the different degrees of influence of different mining areas and different hydrogeological conditions. Affected by the hydrogeology of the mining area, the water porosity of the blastholes in the mining area is more than 70%, and the water fullness of the water holes averages more than 65% of the blasthole depth.

[0003] However, after the blasting area is drilled, the rock slag and rock chips on the hole wall are relatively soft and unstable. During the process of the mixed emulsion explosive truck lowering the pipe to feed the explosives into the blast hole, the delivery pipe will frequently scratch the hole wall, causing rock blocks and rock chips to fall from the hole, thereby resulting in a decrease in the quality of the charge. Utility Model Content

[0004] In order to solve or partially solve the problems existing in the related art, the present application provides a deep hole auxiliary explosive delivery device for an open-pit mine mixed emulsion explosive truck.

[0005] To achieve the above objectives, this application is implemented through the following technical solutions:

[0006] A deep hole auxiliary drug delivery device for an open-pit mine mixed emulsion explosive vehicle comprises a drug delivery pipe and a blasthole, one end of the drug delivery pipe is connected to the mixed emulsion explosive vehicle, and the deep hole auxiliary drug delivery device for an open-pit mine mixed emulsion explosive vehicle further comprises:

[0007] a support ring having an inner diameter greater than the inner diameter of the blasthole;

[0008] A first protective ring is arranged inside the support ring and on the same horizontal plane as the support ring, and a pulley is provided on the first protective ring, and the pulley is in sliding contact with the drug delivery tube;

[0009] A second guard ring is arranged parallel to and below the first guard ring. The inner diameters of the first guard ring and the second guard ring are consistent and both are smaller than the inner diameter of the blast hole.

[0010] Optionally, a first connecting rod is provided between the support ring and the first protective ring, and at least one first connecting rod is provided.

[0011] Optionally, a second connecting rod is provided between the first guard ring and the second guard ring, and at least a pair of second connecting rods is provided.

[0012] Optionally, a mounting seat is fixed on the first protective ring, and the pulley is mounted on the first protective ring through the mounting seat.

[0013] Optionally, a first handle is provided on the mounting seat, and two ends of the first handle are respectively fixedly connected to two sides of the mounting seat.

[0014] Optionally, a second handle is provided on the support ring.

[0015] Optionally, the front view surface of the mounting seat is U-shaped.

[0016] The beneficial effects of the present application are as follows: when the drug delivery tube of the present application performs a lifting and lowering movement in the annular protective space formed by the first protective ring and the second protective ring, due to the supporting auxiliary effect of the pulley and the protective effect of the first protective ring and the second protective ring, the drug delivery tube cannot contact the mouth wall and the hole wall of the blast hole during the lifting and lowering process, thereby avoiding the problem of scratching the hole mouth wall and causing rock blocks and rock chips to fall from the hole mouth, thereby improving the charging quality. In addition, the drug delivery tube can be filled with explosives while rising, so that the drug column can remain continuous, thereby further ensuring the charging quality.

[0031] In order to make the purpose, technical solutions and beneficial effects of the present application clearer, the preferred embodiments of the present application will be described in detail below in conjunction with the accompanying drawings to facilitate understanding by technical personnel.

[0032] Embodiment 1:

[0033] See also Figures 1 to 4 A deep hole auxiliary drug delivery device for mixed emulsion explosive vehicle in an open-pit mine, comprising a drug delivery pipe 1 and a blasthole 2, one end of the drug delivery pipe 1 is connected to the mixed emulsion explosive vehicle, and the deep hole auxiliary drug delivery device for mixed emulsion explosive vehicle in an open-pit mine also includes:

[0034] A support ring 3, the inner diameter of which is larger than the inner diameter of the blast hole 2;

[0035] A first protective ring 4 is arranged inside the support ring 3 and is located on the same horizontal plane as the support ring 3. A pulley 5 is provided on the first protective ring 4. The pulley 5 is in sliding contact with the drug delivery tube 1.

[0036] The second guard ring 6 is arranged parallel to and below the first guard ring 4 . The inner diameters of the first guard ring 4 and the second guard ring 6 are consistent and both are smaller than the inner diameter of the blast hole 2 .

[0037] Specifically, the support ring 3 is an irregular ring shape, and its inner diameter is larger than the inner diameter of the borehole 2, so that the support ring 3 can be placed above the borehole 2. The first protective ring 4 and the second protective ring 6 are both ring-shaped, and the two are located on the same vertical plane. The inner diameters of the first protective ring 4 and the second protective ring 6 are consistent and smaller than the inner diameter of the borehole 2, so that when the support ring 3 is placed above the borehole 2, the second protective ring 6 can extend into the borehole 2, and the first protective ring 4 and the second protective ring 6 form an annular protective space, and the drug delivery tube 1 rises and falls in the annular protective space; the middle part of the pulley 5 has a groove, and the drug delivery tube 1 is placed in the groove. The pulley 5 is in sliding contact with the drug delivery tube 1, and the groove is used to limit the movement trajectory of the drug delivery tube 1 to reduce its shaking amplitude;

[0038] When in use, by placing the support ring 3 above the blasthole 2, the second guard ring 6 is extended into and suspended in the blasthole 2, and the end of the drug delivery tube 1 away from the mixed emulsion explosive vehicle is placed in the groove of the pulley 5, and the movement of the mixed emulsion explosive vehicle drives the drug delivery tube 1 to move downward on the pulley 5, and the drug delivery tube 1 passes through the first guard ring 4 and the second guard ring 6 from top to bottom to enter the blasthole 2. When the drug delivery tube 1 descends to the target depth, the mixed emulsion explosive vehicle is controlled to fill the explosive into the blasthole 2 through the drug delivery tube 1. As the explosive column rises, the mixed emulsion explosive vehicle is controlled to move in the opposite direction, driving the drug delivery tube 1 to rise at the target speed on the pulley 5, so that the drug delivery tube 1 is filled with explosives while rising, thereby ensuring the continuity of the explosive column and the charging quality;

[0039] In this embodiment, when the drug delivery tube 1 performs lifting and lowering movement in the annular protective space formed by the first protective ring 4 and the second protective ring 6, due to the supporting auxiliary function of the pulley 5 and the protective function of the first protective ring 4 and the second protective ring 6, the drug delivery tube 1 cannot contact the mouth wall and the hole wall of the blasthole 2 during the lifting and lowering process, thereby preventing the drug delivery tube 1 from scratching the hole wall and causing the hole mouth rock blocks and rock chips to fall, thereby improving the charging quality. In addition, the drug delivery tube 1 can be filled with explosives while rising, so that the drug column can remain continuous, thereby further ensuring the charging quality;

[0040] After the device is put into use, the vehicle-mounted drug delivery tube reel system cooperates with the auxiliary device to effectively solve the problem of manual retraction and release of the drug delivery tube, reduce the labor intensity of manual assistance, and improve the efficiency of charging construction.

[0041] It should be noted that the support ring 3 can also be a regular circular ring, or other shapes, such as square, elliptical, in short, as long as the size of the support ring 3 is larger than the inner diameter of the bore 2, it can achieve the supporting function.

[0042] Embodiment 2:

In this way, the support ring 3 and the first protective ring 4 are connected to form an integral structure, thereby enhancing the stability of the two. By increasing the number of first connecting rods 7, the connection strength and stability of the two are further enhanced. In this embodiment, four first connecting rods 7 are provided, and the first connecting rods 7 can be evenly arranged at equal intervals, or they can be arranged as follows.

[0046] Specifically, the upper end of the second connecting rod 8 is fixedly connected to the lower end of the first protective ring 4, and the lower end of the second connecting rod 8 is fixedly connected to the upper end of the second protective ring 6. In this way, the first protective ring 4 and the second protective ring 6 are connected to form an integral structure, thereby enhancing the stability of the two. At the same time, the combination of the first protective ring 4, the second protective ring 6 and the second connecting rod 8 facilitates the formation of an annular protective space to limit the movement of the drug delivery tube 1 and prevent it from contacting the mouth wall and hole wall of the blast hole 2.

[0047] In this embodiment, two pairs of second connecting rods 8 are provided at equal intervals to ensure the connection strength and stability between the first protective ring 4 and the second protective ring 6 .

[0048] Further and optionally, a mounting seat 9 is fixed on the first protection ring 4 , and the pulley 5 is mounted on the first protection ring 4 through the mounting seat 9 .

[0049] Specifically, two support rods 12 are fixedly connected between the support ring 3 and the first protection ring 4. The lower end surface of the mounting seat 9 is fixedly connected to the first protection ring 4 and the upper ends of the two support rods 12 respectively. The mounting seat 9 is provided with two holes for allowing the rotating shaft of the pulley 5 to pass through. The rotating shaft is passed through the holes, and the pulley 5 is rotatably mounted on the mounting seat 9 through the rotating shaft.

[0050] In this embodiment, the mounting seat 9 is provided to support the pulley 5, thereby enhancing the stability of the pulley 5 when rotating.

[0051] Further and optionally, a first handle 10 is provided on the mounting seat 9 , and two ends of the first handle 10 are fixedly connected to two sides of the mounting seat 9 respectively.

[0052] Specifically, the two ends of the first handle 10 are fixedly connected to the two sides of the mounting base 9, and the first handle 10 has a certain angle with the horizontal plane, so that the first handle 10 is inclined. The first handle 10 is provided to facilitate the movement of the entire device, and it is also convenient to move the mounting base 9 after disassembly.

[0053] Further and optionally, a second handle 11 is provided on the support ring 3 .

[0054] Specifically, the upper end of the support ring 3 is fixedly connected to the lower end of the second handle 11, the angle between the second handle 11 and the horizontal plane is 90°, and the second handle 11 is opposite to the first handle 10. By setting the second handle 11 to cooperate with the first handle 10, the overall movement of the device is further facilitated.

[0055] Further and optionally, the front view surface of the mounting seat 9 is U-shaped.

[0056] Specifically, the mounting seat 9 is composed of two side walls and a bottom plate, so that its front view is U-shaped, so as to facilitate the pulley 5 to be rotatably installed in the U-shaped groove of the mounting seat 9.

[0057] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the present application rather than to limit it.
