Description

Technical Field

[0001] The invention relates to the technical field of drilling equipment, in particular to a drill rod drilling device. Background Art

[0002] Drill rods are important tools for connecting drill bits and rock drills in well engineering. Drill rods are generally divided into two types: hexagonal hollow steel and hollow round steel. Drill rods can be used as fixing tools for cables, pipes and other equipment in underground work to ensure that the equipment can be firmly installed underground to avoid safety accidents caused by equipment falling or sliding. Drill rods transmit power and signals by connecting various equipment, such as cables, pumps and various sensors, to ensure the normal operation of underground equipment and data transmission. During the drilling process, drill rods are often used to construct wellbores, help fix the well wall, and prevent wellbore collapse, thereby ensuring the safety of the wellhead.

[0003] In the related art, the front end of the drill rod is a pyramid structure, and its side wall is provided with two symmetrically distributed positioning surfaces near the rear end. The rear end of the drill rod is also provided with a positioning surface. The drill rod is usually deep-hole drilled using a deep-hole drilling machine.

[0004] A Chinese patent with authorization announcement number CN117102542B discloses a deep hole processing device, a processing method and a deep hole drilling machine. The patent includes: a base plate, a power head assembly, a rotating assembly, a linear drive assembly and an oiler assembly. The base plate is provided with a slide rail group along the length direction. The power head assembly includes a drill rod, a drill bit and a guide sleeve. The rotating assembly is used to drive the drill rod to rotate. The linear drive assembly is used to drive the drill rod to slide axially. The oiler assembly includes an oiler body and an oiler pressure shaft. The oiler body is a hollow cavity. A guide channel is provided at the center of the oiler pressure shaft. A through hole is provided on the oiler pressure shaft, connecting the hollow cavity and the guide channel. An expansion joint is left between the guide channel and the drill rod. A first chip removal hole is provided in the drill bit, a guide hole is provided in the guide sleeve, a second chip removal hole is provided in the drill rod, and a plurality of spiral guide grooves are provided on the outer circumferential surface of the guide sleeve.

[0005] The above patent sets a guide sleeve between the drill bit and the drill rod. The swirl pressure formed by multiple spiral guide grooves can accelerate the flow speed of the coolant in the drill hole, quickly cool down the drill bit, and avoid overheating and nodule formation on the drill bit. During the high-speed operation of the drill bit, the convex edge that is higher than the spiral guide groove can directionally divert the coolant, so that the liquid quickly enters the first chip removal hole of the drill bit. The coolant overflowing in the gap between the convex edge and the machined hole wall will form a centripetal pressure on the guide sleeve in the circumferential direction to ensure the centering accuracy of the drill bit in the drill hole, thereby improving the accuracy of deep hole processing.

[0006] However, the above patent requires manual loading and manual clamping of the drill rod to the fixture of the deep hole drilling machine, which is time-consuming and labor-intensive and affects the processing efficiency. Summary of the invention

[0031] like Figures 1 to 5 As shown, the drill rod drilling device of the present invention comprises: a frame 1 and a feeding assembly.

[0032] Specifically, Figure 1 and Figure 2 As shown, the frame 1 is a frame structure, and a drilling mechanism is provided at the rear end of the frame 1.

A motor is provided in the frame 1, and the motor is used to drive the lead screw to rotate, thereby driving the driving seat 22 to move along the axial direction of the lead screw.

[0033] like Figures 1 to 3As shown, the feeding assembly includes a conveyor belt 31, a lifting plate 32 and a positioning seat 33. There are two conveyor belts 31, which are respectively located on the left and right sides of the frame 1. The conveyor belt 31 is provided with multiple baffles, and compartments are formed between adjacent baffles. The drill rod can be placed in the compartments, so as to ensure that the drill rod rolls on the conveyor belt 31 when the drill rod is transported. The lifting plate 32 is arranged at the front end of the frame 1. The frame 1 is provided with a lifting mechanism, which includes a transmission chain and a drive motor. The transmission chain rotates and cooperates with the frame 1. The drive motor is fixedly connected to the bottom of the frame 1, and its output end is meshed with the transmission chain. The lifting plate 32 is fixedly connected to the transmission chain. The drive motor is used to drive the transmission chain to move cyclically, thereby driving the lifting plate 32 to move up and down. The lifting plate 32 is tilted, and its front end is lower than its rear end. The lifting plate 32 is also provided with a positioning block 321, and the positioning block 321 is also provided with an arc groove. The drill rod can be placed in the arc groove, so as to prevent the drill rod from rolling on the lifting plate 32. A limit block 6 is also provided at the front end of the frame 1, and a push plate 7 is provided on the limit block 6. The push plate 7 is elastically connected to the limit block 6 through a first elastic member, and the first elastic member is a spring.

[0034] like Figure 1 , Figure 2 and Figure 4 As shown, a slide rail is provided on the frame 1, and a positioning seat 33 is slidably matched on the slide rail. A driving unit is provided in the positioning seat 33, and the driving unit is a cylinder, which is used to drive the positioning seat 33 to move along the slide rail. A bevel block 331 is provided at the front end of the positioning seat 33, and a first clamping member 4 is also provided at the front end of the positioning seat 33, and a second clamping member 5 is provided at the rear end. The first clamping member 4 includes a first clamping rod and a second clamping rod, and the first clamping rod and the second clamping rod are both slidably matched on the positioning seat 33. A driving member is provided in the first clamping rod and the second clamping rod, and the driving member is a cylinder, which is used to drive the first clamping rod to move closer to or away from each other. The second clamping member 5 has the same structure as the first clamping member 4, and includes a third clamping rod 51 and a fourth clamping rod 52. The top ends of the third clamping rod 51 and the fourth clamping rod 52 are also provided with a buffer block 8, which is made of rubber, and the top ends of the buffer blocks 8 are bevel ends. The two buffer blocks 8 are symmetrically distributed on the left and right, and a V-shaped groove is formed between the two buffer blocks 8. The third clamping rod 51 is provided with a limiting protrusion 511 on a side wall thereof close to the fourth clamping rod 52 .

[0035] like Figure 1 and Figure 5As shown, a feed box 9 is also provided at the bottom of the frame 1. The front end of the feed box 9 is abutted and slidably matched with the lifting plate 32. A limit plate 10 is provided at the top of the feed box 9. The limit plate 10 is elastically connected to the feed box 9 through a second elastic member, which is a spring. The top of the limit plate 10 can abut against the positioning seat 33. The top of the limit plate 10 is a double-bevel structure. When the positioning seat 33 moves to contact the limit plate 10, it can move along the slope of the limit plate 10 and squeeze the limit plate 10 downward. A buffer plate 11 is also provided in the feed box 9. The buffer plate 11 is elastically connected to the bottom end of the feed box 9 through a third elastic member, which is a spring. A collection box 12 is also provided on the left side of the feed box 9. The collection box 12 is connected to the feed box 9. The top surface of the buffer plate 11 is a slope structure, and its left end is lower than its right end.

[0036] According to the drill rod drilling device of the present invention, the lifting plate 32 is located at the bottom of the frame 1, and the transmission belt transports the drill rod to be drilled to the lifting plate 32, and the lifting plate 32 is driven to move upward by the lifting mechanism until the lifting plate 32 moves to the uppermost end. The positioning seat 33 moves forward, and the inclined surface block 331 gradually approaches the rear end of the drill rod until the inclined surface block 331 extends between the drill rod and the lifting plate 32. Under the push of the inclined surface block 331, the rear end of the drill rod is lifted upward, and at this time, the front end of the drill rod can stop with the limit block 6, and the limit block 6 prevents the drill rod from moving forward. When the center of gravity of the drill rod is located behind the inclined block 331, the rear end of the drill rod falls on the buffer block 8 at the top of the third clamping rod 51 and the fourth clamping rod 52, and slides down along the V-shaped groove formed between the two buffer blocks 8. When the positioning surface of its side wall fits with the limiting protrusion 511, the rear end of the drill rod can slide down along the gap between the third clamping rod 51 and the fourth clamping rod 52 until its bottom contacts the positioning plate. When the positioning seat 33 moves to the front end, the front end of the positioning seat 33 stops against the push plate 7, and the push plate 7 can push the drill rod backward to prevent the front end of the drill rod from extending out of the positioning seat 33. The positioning seat 33 moves backward until its rear end stops against the positioning platform 21. At this time, the positioning surface at the rear end of the drill rod stops against the positioning flange on the positioning platform 21. The driving member drives the first clamping rod and the second clamping rod and the third clamping rod 51 and the fourth clamping rod 52 to approach each other, thereby tightly clamping the drill rod to fix the drill rod, and then drilling the drill rod through the drill rod 23.

[0037] After the drilling is completed, the first clamping member 4 and the second clamping member 5 release the drill rod with the drilled hole, and the positioning seat 33 moves forward. At this time, the lifting plate 32 lifts the next drill rod to be drilled upward. In the process of the positioning seat 33 moving forward, the positioning seat 33 will pass over the limit plate 10, and the rear end of the drill rod to be processed will stop at the front end of the processed drill rod, and push the front end of the processed drill rod to be lifted. The processed drill rod tilts out of the positioning seat 33 from the rear end of the positioning seat 33, slides downward along the limit plate 10, and finally falls on the buffer plate 11. Under the action of the gravity of the processed drill rod, the buffer plate 11 moves downward to prevent the processed drill rod from hindering the positioning seat 33 from moving backward. The processed drill rod moves along the inclined surface of the buffer plate 11 to the collection box 12 to realize automatic unloading.
