Technical Field

[0001] This invention relates to the field of drilling machine technology, and in particular to a drill rod connection structure for a blasting drilling machine. Background Technology

[0002] The drill rod docking structure for blasting drilling machines is a type of heavy machinery used in mining, tunnel engineering, building demolition, and other fields. It is mainly used to drill holes in rocks or concrete so that explosives can be loaded for subsequent blasting operations.

[0003] Currently, the drill rods of the drill rod splicing structure used in blasting drilling machines are too long, the drilling machines are too large, and the operation is inconvenient. Existing drill rod splicing is mostly done manually after the machine is stopped, and the drive structure is moved after the machine is stopped to replace the drive connection parts of the drill rod, which affects the efficiency of construction. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned shortcomings by providing a drill rod connection structure for a blasting drilling machine. This structure enables automatic and rapid assembly of drill rods without stopping the machine, and facilitates the replacement of the drill rods after drive installation. It also reduces the size of the drilling machine, makes the machine easier to operate, and improves construction efficiency.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a drill rod docking structure for a blasting drilling machine, comprising: A drill rod storage rack, installed on the drilling machine, is used to store drill rods; A docking part is provided on one side of the drill rod storage rack and on the drilling machine for removing the drill rod from the drill rod storage rack. The drill rod is provided with a driven gear. The drive unit, mounted on the drilling machine, includes a first drive unit and a second drive unit. The second drive unit is sleeved on the outer wall of the drill rod and is used to drive the drill rod to move up and down and to drill. The first drive unit is located at the top of the drill rod and is used to clamp the drill rod and to increase the rotation speed of the drill rod to be similar to that of another drill rod, thereby connecting the two drill rods. A connector is located at one end of the drill pipe; The mounting head is located at the other end of the drill rod. The docking part cooperates with the driving part to align the drill rod on the drill rod storage rack with the drill rod working on the drilling machine. The first driving unit and the second driving unit cooperate to install the two drill rods. The disassembly section is located on the second drive unit and is sleeved on the drill pipe. It is used to separate the connector and the mounting head.

[0006] Furthermore, the drill rod storage rack includes a bracket fixedly mounted on the drilling machine and a first telescopic member disposed at one end of the bracket, wherein the telescopic end of the first telescopic member is provided with a push plate; It also includes ball screws symmetrically arranged on the push plate, each ball screw having a telescopic rod at its end, and each telescopic rod having a baffle at its telescopic end. The ball screws are used to drive the telescopic rods and the baffles to rotate, thereby releasing the drill rod.

[0007] Furthermore, the docking part includes a second telescopic member disposed on the drilling machine and a clamping member disposed on the telescopic end of the second telescopic member, wherein the clamping member is provided with a third telescopic member for clamping the drill rod.

[0008] Furthermore, the second drive unit includes a lifting component mounted on the drilling machine and a drive source mounted on the lifting component; It also includes clamping components installed on the lifting components for clamping drill rods.

[0009] Furthermore, the drive source includes a fourth telescopic member disposed on the lifting member and a drive member disposed at the end of the fourth telescopic member, and the output shaft of the drive member is provided with a driving gear that meshes with the driven gear.

[0010] Furthermore, the clamping member includes a connecting rod disposed on the lifting member and a roller disposed at the end of the connecting rod and sleeved on the outer wall of the drill rod, and a fifth telescopic member for clamping the drill rod is disposed on the inner side of the roller.

[0011] Furthermore, the second drive unit has the same structure as the first drive unit, and the second drive unit is located below the first drive unit.

[0012] Furthermore, the disassembly unit includes a lifting body disposed on the top of the second drive unit and a support frame disposed on the lifting body; It also includes a sixth telescopic member and a seventh telescopic member symmetrically arranged on the support frame, wherein the telescopic end of the seventh telescopic member is provided with a pressure frame.

[0013] Furthermore, the connector includes a connector sleeve disposed on one side of the drill pipe and sliders symmetrically disposed on the outer wall of the connector sleeve; It also includes a fixing ring symmetrically arranged on the inner wall of the plug-in cylinder and a first spring arranged at the bottom of the fixing ring. The bottom of the first spring is fixedly provided with a movable ring that is slidably connected to the inner wall of the plug-in cylinder, and the bottom of the movable ring is fixedly provided with an inclined plate. It also includes an elastic outer cylinder symmetrically arranged inside the plug-in cylinder and a plug rod arranged inside the elastic outer cylinder and extending to the outside of the plug-in cylinder, wherein the outer wall of the plug rod is provided with a stop bar; It also includes a push ring frame located at the bottom of the movable ring, wherein the movable ring, the inclined plate and the push ring frame are integral.

[0014] Furthermore, the mounting head includes a mounting cylinder disposed at the other end of the drill pipe and a protective cylinder disposed on the mounting cylinder; The mounting cylinder has a groove adapted to the slider, and the mounting cylinder has a hole for inserting the plug rod. The mounting cylinder has a cylindrical groove for mounting the protective cylinder, and the protective cylinder is provided with a third spring, which is located in the cylindrical groove.

[0015] The beneficial effects of this invention are reflected in: This invention involves moving a drill rod on a support via a first telescopic component on a drill rod storage rack. The first telescopic component moves a push plate, which in turn rotates a ball screw. The ball screw then rotates a telescopic rod and a baffle, moving the drill rod to a clamping position. A second telescopic component moves the clamping component to the drill rod position, and a third telescopic component clamps the drill rod. The drill rod is then moved by the second telescopic component to a position directly above the drill rod in the borehole. A first drive unit clamps the drill rod, and the rotation speed of the drill rod driven by the first drive unit is similar to the speed of the working drill rod driven by the second drive unit. The drill rod descends, and the connector on the drill rod is inserted into the mounting head of the working drill rod. The connector slider aligns with the chute body, and the push ring frame on the connector presses against the mounting cylinder. The push ring frame pushes a movable ring to compress a spring and a fixed ring, causing the inclined plate on the movable ring to move away from the baffle. Finally, the insert rod on the elastic outer cylinder is inserted into the insertion hole, thus enabling the connection of two drill rods. The process involves docking, where the second drive unit drives the drill rod downwards to drill a hole. Similarly, the first drive unit, in conjunction with the docking part, removes the drill rod and installs it onto the drill rod driven by the second drive unit. Then, the first drive unit drives the newly installed drill rod to rotate, and the second drive unit moves it upwards to the driven gear of the previous drill rod, driving the drill rod to continue drilling downwards. The first drive unit moves upwards and, in conjunction with the first drive unit, installs the drill rod, thus enabling the replacement of the drive unit to drive the drill rod. When the drill rod needs to be disassembled, the drill rod is stationary, and the sixth telescopic component on the disassembly part presses against the protective cylinder. The lifting body moves the protective cylinder downwards, and then the seventh telescopic component approaches the installation head. The drill rod is rotated, and then the seventh telescopic component pushes the pressure frame into the elastic outer cylinder. The docking part disassembles the drill rod, and the drill rod is moved to the drill rod storage rack. This allows for automatic and rapid splicing of drill rods without stopping the machine, as well as changing the drive unit to drive the installed drill rod, reducing the size of the drilling machine, facilitating operation, and improving construction efficiency.

[0033] In use, the drill rod 6 to be installed rotates at a similar speed to the working drill rod 6. The insertion joint 7 is inserted into the installation head 8. The installation cylinder 81 presses against the push ring frame 79. The push ring frame 79 pushes the movable ring 74 to press against the first spring 73. The inclined plate 75 moves away from the stop bar 78, so that the insertion rod 77 is inserted into the insertion hole under the action of the elastic outer cylinder 76, thus installing the installation head 8 and the insertion joint 7.

[0034] In a specific embodiment, the mounting head 8 includes a mounting cylinder 81 disposed at the other end of the drill rod 6 and a protective cylinder 82 disposed on the mounting cylinder 81.

[0035] In use, the sixth telescopic member 53 clamps the protective cylinder 82, and the lifting body 51 drives the protective cylinder 82 to press the third spring. The height at which the protective cylinder 82 descends is the same as the height at which the seventh telescopic member 54 descends. The second drive unit 4 drives the drill rod 6 to rotate. The seventh telescopic member 54 and the pressure frame 55 face the insertion rod 77. The seventh telescopic member 54 squeezes the insertion rod 77, causing the insertion rod 77 to enter the insertion cylinder 71. Then, the two drill rods 6 are disassembled through the docking part 2. Driven by the docking part 2 and the operation of the drill rod storage rack 1, the drill rod 6 is placed on the drill rod storage rack 1.

[0036] During operation and installation, firstly, the second drive unit 4 on the drilling machine, with the roller 432 on the second drive unit 4 sleeved on the outside of the working drill rod 6, clamps the drill rod 6 through the fifth telescopic member 433, and the fourth telescopic member drives the drive member and the active gear to approach the driven gear of the drill rod 6.

Then, the first telescopic member 12 pushes the push plate 13, and the push plate 13 pushes the drill rod 6 to slide on the bracket 11. Then, the push plate 13 drives the ball screw 14 to rotate on the bracket 11, and the ball screw 14 drives the telescopic rod 15 and the baffle 16 to rotate, loading and unloading the drill rod 6. Then, the second telescopic member 21 drives the clamping member 22 to be positioned at the point where the drill rod 6 is lowered on the bracket 11. The third telescopic member 23 drives the clamping member 22 to clamp the drill rod 6. Then, the second telescopic member 21 drives the drill rod 6 to be aligned with the drill rod 6 clamped by the second drive unit 4. Then, the first drive unit 3 moves on the drill rod 6 to be installed, driving the drill rod 6 to be installed to accelerate to the same speed as the working drill rod 6 clamped by the second drive unit 4. Then, the first drive unit 3 drives the drill rod 6 to be installed to be connected and installed with the working drill rod 6. During the connection and installation, the insertion sleeve 71 is installed inside the installation sleeve 81. Then, by pushing the ring frame 79 to contact the bottom wall of the installation sleeve 81, the connection is completed. The push ring frame 79 presses the first spring 73 on the movable ring 74, and the movable ring 74 drives the inclined plate 75 away from the stop bar 78 and the insertion rod 77. The elastic outer cylinder 76 expands, and the insertion rod 77 is inserted and limited on the mounting cylinder 81 and the insertion cylinder 71. The inclined plate 75 moves away from the stop bar 78, and the second drive unit 4 drives the working drill rod 6 to continue drilling downward. The first drive unit 3 cooperates with the docking part 2 to remove the drill rod 6 from the drill rod storage rack 1 and continue to dock and install it. Then, when the first drive unit 3 drives the newly installed drill rod 6 to rotate, the second drive unit 4 moves to the driven gear of the middle drill rod 6, which is convenient for replacing the drive part of the second drive unit 4. When it is necessary to disassemble the drill rod 6, the stationary drill rod 6 is pressed against the protective cylinder 82 by the sixth telescopic member 53 on the disassembly part 5. The protective cylinder 82 is moved down by the lifting body 51, and then approaches the installation head 8 by the seventh telescopic member 54. The drill rod 6 is rotated, and then the insertion rod 77 is pushed into the elastic outer cylinder 76 by the seventh telescopic member 54 and the pressure frame 55. It is moved to the outer wall of the drill rod 6 by the first drive unit 3, clamps the drill rod 6, and pulls out the drill rod 6. Then, the drill rod 6 is clamped by the docking part 2 and moved to the drill rod storage rack 1. This realizes the automatic and rapid splicing of the drill rod 6 without stopping the machine, as well as the replacement of the drive part to drive the installed drill rod 6. This reduces the size of the drilling machine, facilitates the operation of the drilling machine, and improves construction efficiency.
