Description

Technical Field

[0001] The present invention relates to the technical field of mine blasting, in particular to a mine mining blasting drilling device. Background Art

[0002] When a mine is being mined and constructed, it is necessary to blast the mine. Before blasting, holes need to be drilled at the mining location, and sufficient explosives need to be placed in the drilled holes before blasting. The depth of the holes required for mine blasting usually depends on the specific blasting method, which mainly includes shallow hole blasting, medium hole blasting and deep hole blasting. In order to meet the needs of deeper drilling, traditional drilling machines usually need to connect multiple drill rods when performing deeper drilling work, which is cumbersome to operate and has low drilling efficiency.

[0003] In order to solve the above technical problems, the utility model patent with publication number CN217206296U in the prior art provides a drilling device for mining blasting engineering. The drill rod can be easily installed through the clamping mechanism, and additional drill rods can be installed according to the drilling depth. The drill rods can be tightened without the help of tools such as wrenches.

[0004] In the prior art, the requirements of different drilling depths are met by adding multiple sets of drill rods. In actual drilling, the required drilling depth is even far beyond the height of the device itself. If a drill rod with a total length that meets the requirement is to be installed, multiple sets of drill rods or longer drill rods are required to be installed. The multiple sets of drill rods are installed manually, and the installation process is inefficient. The depth of the drill hole may need to be adjusted during the actual drilling process. If the depth is not enough, additional drill rods need to be installed. The drilling depth is limited by the length of the drill rod, and the drill rod length cannot be easily adjusted, resulting in repeated operations in the entire drilling process, which is inefficient.

[0059] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0060] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the present invention provides a mining blasting drilling device, which includes a frame 1, a drilling machine top 2, a positioning frame 3, a slide 4 and other structures.

[0061] A retractable cabin 5 is installed on the frame 1, and a pulling rope 6 is led out downward from the bottom of the side of the retractable cabin 5. A retractable shaft 7 is installed in the retractable cabin 5. The retractable shaft 7 rotates to control the length of the pulling rope 6 led out to the outside of the retractable cabin 5. The pulling rope 6 is generally made of steel wire.

[0062] The top 2 of the drilling machine is connected to the bottom end of the pulling rope 6. A driving cabin 10 is installed at the bottom of the top 2 of the drilling machine. A lift seat 11 that can be raised and lowered is installed in the driving cabin 10. A lift drive assembly 8 is movably connected to the lift seat 11, and the lift drive assembly 8 can drive the lift seat 11 to descend.

[0063] The positioning frame 3 can realize the positioning of the drilling structure in the channel. The positioning frame 3 can be rotatably installed on the peripheral side of the drive cabin 10. The end of the positioning frame 3 is hingedly installed with a positioning plate 12. The lifting seat 11 descends and pushes the positioning frame 3 to rotate outward, so as to drive the positioning plate 12 to move outward and fit against the inner wall of the drilled channel.

[0064] The slide 4 is arranged at the bottom of the drive cabin 10, and a drill rod 13 is installed at the bottom of the slide 4. A rotary drive structure 9 is installed in the slide 4. The rotary drive structure 9 can drive the drill rod 13 to rotate to perform drilling. A slide rail 14 is installed at the bottom of the drive cabin 10, and the slide 4 is slidably arranged in the slide rail 14.

[0065] The drill rod 13 may be configured as a threaded rod structure, and its bottom may be configured as a pointed shape in order to further drill downwards.

[0066] The lifting drive assembly 8 can pass through the lifting seat 11, and its bottom is opposite to the top of the slide 4 to push the slide 4 and the drill rod 13 downward and cooperate with the rotation of the drill rod 13 to complete downward drilling.

[0067] In the present invention, the drilling machine top 2, the drive cabin 10, the slide 4, the drill rod 13, etc. form a drilling structure, and the drilling structure is pulled by the pulling rope 6. The length of the pulling rope led out to the outside of the retracting cabin 5 is controlled by rotating the retracting shaft 7, so as to control the position of the drilling structure deep into the tunnel. First, a hole is opened in the mine through the drilling structure, and then the pulling rope 6 is gradually retracted and released to make the drilling structure go deep into the tunnel. Every time it descends to a certain depth, the drilling structure is fixed to the depth position by the positioning frame 3, and then the drill rod 13 is driven downward to perform drilling work. The drilling of the entire tunnel is achieved through multiple descents and drillings. The depth of the drilling is not limited by the length of the drill rod 13, and the drilling depth can be directly controlled by the pulling rope 6, thereby improving the efficiency of the entire drilling process.

[0068] In the present invention, in order to realize the retraction and extension of the pulling rope 6, it is necessary to rotate the retraction shaft 7. The retraction shaft 7 is externally connected to a drive motor 50. The drive motor 50 can drive the retraction shaft 7 to rotate. Under the action of gravity, the pulling rope 6 led downward is in a vertical state. In addition, in order to allow the pulling rope 6 to pass through the plane of the frame 1 and connect downward to the drilling structure, an opening 48 is provided at the bottom side of the retraction cabin 5, and a through slot 49 for the pulling rope 6 to pass through is provided on the plane of the frame 1. The opening 48 is opposite to the through slot 49. The pulling rope 6 passes through the opening 48 and the through slot 49 in turn and is led downward.

[0069] In the present invention, the lifting drive assembly 8 can not only drive the positioning of the drilling structure, but also drive the drill rod 13 to move downward to cooperate with the drilling work. The lifting drive assembly 8 of the present invention adopts the following preferred embodiments, such as Figure 5 and Figure 6 As shown, the lifting drive assembly 8 includes a driving cylinder 81 and a push rod 82 connected to the output end of the driving cylinder 81; when the driving cylinder 81 is not driven, there is a gap between the bottom of the push rod 82 and the top of the slide 4.

[0070] In the above embodiment, the push rod 82 can pass through the lifting seat 11, and its end is directly above the slide 4. Under the drive of the driving cylinder 81, the push rod 82 moves downward, and after moving downward a certain distance, it can abut against the upper end of the slide 4 and push the slide 4 down.

[0071] The push rod 82 can push the lifting seat 11 to move downward, and the lifting seat 11 can also be reset when the push rod 82 is reset. For this purpose, the present invention makes the following design, such as Figure 5 、 Figure 6 and Figure 7 As shown, the drive cabin 10 is provided with a radial groove 15 along the radial direction, the radial groove 15 connects the inside and outside of the drive cabin 10, a radial rod 16 is connected to the side of the lifting seat 11, and an annular groove 17 is provided on the outer wall of the drive cabin 10. A connecting ring 18 is slidably provided in the annular groove 17, and the outer end of the radial rod 16 is connected to the connecting ring 18.

[0072] A support frame 19 is hinged on the outer periphery of the connecting ring 18 facing the positioning frame 3 , and the outer end of the support frame 19 is hinged on the middle position of the positioning frame 3 , and both the positioning frame 3 and the support frame 19 are tilted downward.

[0073] The radial rod 16 , the lifting seat 11 , and the connecting ring 18 can move up and down together in the vertical direction, so that the lifting seat 11 can drive the connecting ring 18 to move downward through the radial rod 16 .

[0074] like Figure 7 As shown, the drilling machine top 2 is connected to the driving cabin 10 through the connecting column 20, the driving cylinder 81 is installed at the bottom of the drilling machine top 2, and the top of the driving cabin 10 is provided with a first central groove 21 for the push rod 82 to pass through;

[0075] A fixing ring 22 is connected to the outside of the push rod 82, and a first spring 23 is connected between the fixing ring 22 and the lifting seat 11. The first spring 23 is wound around the outside of the push rod 82. A second center groove 24 is provided on the lifting seat 11 for the push rod 82 to pass through, and a third center groove 25 is provided at the bottom of the drive cabin 10 for the push rod 82 to pass through.

[0076] When the driving cylinder 81 is driven, the push rod 82 is driven to move downward, thereby the lifting seat 11 is moved downward by the first spring 23. In the process of the lifting seat 11 following the push rod 82 to move downward, the length of the first spring 23 is basically unchanged, and the lifting seat 11 moves downward and drives the connecting ring 18 to move downward through the radial rod 16, driving the end of the support frame 19 to move downward. In the process of the end of the support frame 19 moving downward, the support frame 19 is rotated as a whole and supports the positioning frame 3 outward, so that the positioning frame 3 rotates outward. In the process of the positioning frame 3 gradually rotating outward, the positioning plate 12 is driven to gradually move outward to a certain extent and abut against the inner wall of the channel. At this time, the lifting seat 11 can no longer move downward, and the push rod 82 continues to move downward. In this process, the first spring 23 will be gradually squeezed, and the downward force applied to the lifting seat 11 will be greater, and the force of the positioning frame 3 pressing the channel outward will gradually increase, thereby achieving further tightening of the positioning frame 3.

[0077] In the present invention, the slide 4 can move downward under the push of the push rod 82, and can also automatically reset when the push rod 82 is reset. For this purpose, the present invention makes the following design, such as Figure 7 As shown, a connecting tube 26 is installed at the bottom of the driving cabin 10, and the connecting tube 26 is opposite to the third center groove 25. A second spring 27 is connected inside the connecting tube 26, and the bottom end of the second spring 27 is connected to the slide seat 4.

[0078] When the push rod 82 gradually moves downward until it abuts against the upper end of the slide 4, it continues to move downward to push the slide 4 downward. During the upward return process of the push rod 82, under the action of the second spring 27, the slide 4 gradually returns upward to its initial position.

[0079] In the present invention, the rotary drive structure 9 can drive the drill rod 13 to rotate, and a drive cavity 28 is provided in the slide 4; Figure 8 As shown, the rotary drive structure 9 includes a driving gear 91 arranged in the driving cavity 28; a limiting arc seat 92 is installed on the side of the driving gear 91, and the limiting arc seat 92 is installed on the inner wall of the driving cavity 28. The driving gear 91 can rotate in the limiting arc seat 92, and a main driving gear 93 is engaged with the side of the driving gear 91, and the main driving gear 93 is connected to the motor.

[0080] The motor drive can drive the main drive gear 93 to rotate, and the rotation of the main drive gear 93 drives the drive gear 91 to rotate. Among them, the limit arc seat 92 plays a role in limiting the position of the drive gear 91 rotating in the drive cavity 28, that is, the drive gear 91 can only rotate at the position corresponding to the limit arc seat 92.

[0081] In the present invention, the drill rod 13 is not in a normally open state, and is driven to rotate only after the drill rod 13 moves down a certain distance to achieve drilling.

[0082] To achieve the above purpose, the present invention is designed as follows: Figure 8 As shown, the driving gear 91 is provided with a fourth central groove 29, a rotating shaft column 30 is provided through the fourth central groove 29, a vertical clamping block 31 is installed on the side of the rotating shaft column 30, and at least part of the groove wall of the fourth central groove 29 is in engagement with the vertical clamping block 31;

[0083] A first transmission disc 32 is mounted on the bottom of the rotating shaft 30;

[0084] A drive shaft 33 is installed on the drill rod 13 , and the drive shaft 33 passes through the bottom of the slide 4 and extends into the drive cavity 28 . The top of the drive shaft 33 is connected to the second transmission disc 34 , and the first transmission disc 32 is directly above the second transmission disc 34 .

[0085] Driven by the vertical clamping block 31 , the driving gear 91 can drive the rotating shaft 30 to rotate.

[0086] The first transmission disc 32 and the second transmission disc 34 are both disc structures with friction surfaces or uneven surfaces installed thereon. When the first transmission disc 32 moves down to the second transmission disc 34, it can immediately drive the second transmission disc 34 to rotate. However, in the initial state, the first transmission disc 32 is away from the second transmission disc 34. In other words, the first transmission disc 32 is in a normally open state, and the second transmission disc 34 is not in a normally open state.

[0087] In the above embodiment, the rotating shaft column 30 can be raised and lowered. When it moves downward, it drives the first transmission plate 32 to move downward to the second transmission plate 34, so that the first transmission plate 32 can drive the second transmission plate 34 to rotate, and drive the drill rod 13 to rotate through the drive shaft 33.

[0088] In order to simultaneously lower the rotating shaft column 30 during the downward movement of the slide 4, the present invention further provides the following design: a movable shaft rod 35 is coaxially mounted on the top of the rotating shaft column 30, and the bottom end of the movable shaft rod 35 is rotatably mounted on the top of the rotating shaft column 30 via a connecting plate 36;

[0089] A mounting plate 37 is installed in the driving chamber 28 for the movable shaft 35 to pass through, and a third spring 38 is connected between the mounting plate 37 and the movable shaft 35;

[0090] An inclined notch 39 is formed on a side wall of the movable shaft 35 .

[0091] In the above embodiment, the rotating shaft column 30 rotates along with the driving gear 91, and under the pulling action of the third spring 38, the movable shaft rod 35 does not rotate. During this process, the rotating shaft column 30 rotates relative to the movable shaft rod 35. In addition, when the movable shaft rod 35 rises or falls, the rotating shaft column 30 also rises or falls accordingly.

[0092] The present invention also has the following design: Figure 8 As shown, a limit frame 40 is installed on the side of the slide rail 14, and a baffle 41 is provided on the side of the limit frame 40 close to the slide rail 14. An inclined slope 42 is provided at the end of the baffle 41. A telescopic frame 43 is telescopically installed on the side of the slide 4, and a fourth spring 44 is connected between the telescopic frame 43 and the side of the slide 4.

[0093] An inclined opening 45 is provided on the side of the telescopic frame 43, and is opposite to the inclined slope 42. A push rod 46 is connected to the inner wall of the telescopic frame 43. The push rod 46 passes through the side wall of the slide 4 and extends into the drive cavity 28. An inclined notch 47 is provided at the end of the push rod 46, and is opposite to the opening edge of the inclined notch 39.

[0094] As the slide 4 gradually moves downward, the inclined opening 45 on the top of the telescopic frame 43 moves toward the side of the slide 4 under the action of the inclined slope 42, and at the same time drives the telescopic frame 43 to move toward the side of the slide 4, drives the support rod 46 to move toward the side of the inclined notch 39, and under the push of the inclined notch 47, the inclined notch 39 moves downward, thereby driving the movable shaft rod 35 to move downward, and at the same time drives the rotating shaft column 30 to move downward.

[0095] During the resetting process of the push rod 82, the slide 4 gradually resets, and the telescopic frame 43 moves away from the limit frame 40. Under the action of the fourth spring 44, the telescopic frame 43 resets, driving the push rod 46 to reset to the initial position, and the movable shaft 35 is also reset to the initial position under the drive of the third spring 38.

[0096] In the present invention, in order to carry out preliminary drilling on the surface of the mine, an installation nacelle 51 is installed at the bottom of the plane of the frame 1 opposite to the through groove 49. The installation nacelle 51 can be used for placing the drilling machine top 2 and the drive cabin 10. Drilling is carried out when the drilling machine top 2 and the drive cabin 10 are in the installation nacelle 51.

[0097] In summary, the main implementation process of the present invention is:

[0098] In the initial state, the drilling machine top 2 and the driving cabin 10 are in the installation nacelle 51, and the driving cylinder 81 drives the push rod 82 to move downward. Since the positioning frame 3 is also in the installation nacelle 51 at this time, the lifting base 11 cannot move downward;

[0099] Pushed by the push rod 82, the slide 4 moves downward along the slide rail 14. During the downward movement, the inclined opening 45 at the top of the telescopic frame 43 moves toward the side of the slide 4 under the action of the inclined slope 42, and at the same time drives the telescopic frame 43 to move toward the side of the slide 4, driving the support rod 46 to move toward the side of the inclined notch 39. Under the push of the inclined notch 47, the inclined notch 39 moves downward, the movable shaft 35 moves downward, and at the same time drives the rotating shaft column 30 downward, driving the first transmission plate 32 to move downward onto the second transmission plate 34, so that the first transmission plate 32 can drive the second transmission plate 34 to rotate, and drive the drill rod 13 to rotate through the drive shaft 33.

[0100] The drill rod 13 moves downward along with the slide 4 and rotates simultaneously to achieve preliminary downward drilling;

[0101] After drilling to a certain depth, the driving cylinder 81 is reset, driving all the structures to reset;

[0102] The driving motor 50 drives the retracting shaft 7 to rotate, and the pulling rope 6 gradually extends downward to a certain height, driving the drilling structure to move downward to a certain height;

[0103] Then, the driving cylinder 81 is driven to move the push rod 82 downward. If the push rod 82 has not yet been separated from the mounting nacelle 51, the above steps are repeated.

[0104] If the nacelle 51 has been detached from the installation nacelle and entered the hole drilled in the aforementioned process, the push rod 82 drives the lifting seat 11 to move downward. As the lifting seat 11 follows the push rod 82 downward, the lifting seat 11 moves downward and drives the connecting ring 18 downward through the radial rod 16, driving the end of the support frame 19 downward. As the end of the support frame 19 moves downward, the support frame 19 rotates as a whole and supports the positioning frame 3 outward, causing the positioning frame 3 to rotate outward. As the positioning frame 3 gradually rotates outward, it drives the positioning plate 12 gradually outward to abut against the inner wall of the hole.

[0105] The push rod 82 continues to move downward and pushes the slide 4 to move downward along the slide rail 14. During the downward movement, the first transmission plate 32 gradually moves downward to the second transmission plate 34, so that the first transmission plate 32 can drive the second transmission plate 34 to rotate, and drive the drill rod 13 to rotate through the drive shaft 33.

[0106] The drill rod 13 is lowered and rotated at the same time to achieve deeper drilling;

[0107] Continue to lower the pulling rope 6 and repeat the above steps until the hole is drilled to a preset depth. In the process of continuously lowering the pulling rope 6, the drilling structure performs repeated drilling and resetting actions.

[0108] The above embodiments are merely exemplary embodiments of the present application and are not intended to limit the scope of the present application. The scope of protection of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and scope of protection of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the scope of protection of the present application.
