Description

Technical Field

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

[0002] A drill rod is an important tool for connecting a drill bit and rock drilling in roadway engineering. Drill rods are generally divided into two types: hexagonal hollow steel and hollow round steel. In underground work, a drill rod can be used as a fixing tool for equipment such as cables and pipe columns to ensure that the equipment can be firmly installed underground and prevent safety accidents caused by the equipment falling or slipping; the drill rod transmits power and signals by connecting various equipment, such as cables, pumps, and various sensors, to ensure the normal operation and data transmission of underground equipment; during the drilling process, drill rods are commonly used to construct wellbores, help fix the wellbore wall, and prevent the wellbore from collapsing, thus ensuring the safety of the wellhead.

[0003] In related technologies, the front end of the drill rod is a pyramid structure, and two symmetrically distributed positioning surfaces are provided on the side wall near the rear end. A positioning surface is also provided at the rear end of the drill rod. Usually, a deep hole drilling machine is used to drill deep holes in the drill rod.

[0004] Chinese Patent with the authorization announcement number CN117102542B discloses a deep hole processing device, processing method, and deep hole drilling machine. The patent includes: a bottom plate, a power head assembly, a rotating assembly, a linear driving assembly, and an oil feeding device assembly. The bottom 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 diversion sleeve. The rotating assembly is used to drive the drill rod to rotate, the linear driving assembly is used to drive the drill rod to slide axially, the oil feeding device assembly includes an oil feeding main body and an oil feeding pressing shaft. The oil feeding main body is a hollow cavity, a diversion channel is provided in the center of the oil feeding pressing shaft, through holes are provided on the oil feeding pressing shaft to communicate the hollow cavity and the diversion channel. There is a telescopic gap between the diversion channel and the drill rod. A first chip removal hole is provided in the drill bit, a diversion hole is provided in the diversion sleeve, a second chip removal hole is provided in the drill rod, and a plurality of spiral diversion grooves are provided on the outer cylindrical surface of the diversion sleeve.

[0005] Through the above patent, by setting a diversion sleeve between the drill bit and the drill rod, the swirling pressure formed by a plurality of spiral diversion grooves can accelerate the flow rate of the coolant in the drill hole, play a role in quickly cooling the drill bit, and avoid the phenomenon of overheating and nodulation of the drill bit. During the high-speed rotation of the drill bit, the convex edge higher than the spiral diversion groove can direct the diversion of the coolant, so that the liquid quickly enters the first chip removal hole of the drill bit, and the coolant overflowing in the gap between the convex edge and the processed hole wall will form a centripetal pressure on the circumferential direction of the diversion sleeve 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 onto the fixture of the deep hole drilling machine, which is time-consuming and laborious and affects the processing efficiency. Summary of the Invention

[0007] The present invention provides a drill rod drilling device, aiming to solve the problems of manual feeding and clamping of drill rods in the related art.

[0008] The drill rod drilling device of the present invention includes: a frame and a feeding assembly;

[0009] A drilling mechanism is provided on the frame;

[0010] The feeding assembly includes a conveyor belt, a lifting plate and a positioning seat. The conveyor belt is arranged beside the frame. The lifting plate is slidably fitted on the frame and can move up and down. The positioning seat is slidably fitted on the frame and is located between the lifting plate and the drilling mechanism. An inclined surface block is provided at one end of the positioning seat close to the lifting plate. The positioning seat is provided with a first clamping member and a second clamping member, and the first clamping member and the second clamping member are distributed at intervals.

[0011] Beneficial effects: The lifting plate is located at the bottom of the frame. The conveyor belt transports the drill rod to be drilled onto the lifting plate. The lifting plate is driven by a lifting mechanism to move upward until the lifting plate moves to the uppermost end. The positioning seat moves forward, and the inclined surface block gradually approaches the rear end of the drill rod until the inclined surface block extends between the drill rod and the lifting plate. Under the push of the inclined surface block, the rear end of the drill rod is lifted upward. At this time, the front end of the drill rod can abut against the limiting block, and the limiting block prevents the drill rod from moving forward. When the center of gravity of the drill rod is behind the inclined surface block, the rear end of the drill rod falls on the second clamping member. At this time, the first clamping member and the second clamping member can clamp the drill rod to realize the positioning of the drill rod. The positioning seat moves backward until the drill rod abuts against the drilling mechanism, and at this time, the drill rod can be drilled.

[0012] Preferably, a limiting block is provided at the end of the frame, and the limiting block can abut against the drill rod.

[0013] The effect is that the limiting block is provided to prevent the drill rod from moving forward when the positioning seat moves forward to lift the drill rod, resulting in the inability to lift the drill rod.

[0014] Preferably, a push plate is further provided on the limiting block, and the push plate is connected to the limiting block through a first elastic member, and the push plate can abut against the drill rod.

[0015] Preferably, a positioning block is provided on the lifting plate, and an arc-shaped groove is provided on the positioning block.

[0016] The effect is that the drill rod is located in the arc-shaped groove on the positioning block, thereby realizing the positioning of the drill rod and making the drill rod on the same axis as the inclined surface block, the first clamping member and the second clamping member.

[0017] Preferably, the lifting plate is inclined, and the end close to the positioning seat is higher than the end far from the positioning seat.

[0018] Its effect is that: the lifting plates are inclined and distributed, which is beneficial for the inclined blocks to extend into between the drill rod and the lifting plates, facilitating the lifting of the drill rod.

[0019] Preferably, the first clamping member includes a first clamping rod and a second clamping rod. The first clamping rod and the second clamping rod are spaced apart and both are slidably engaged with the positioning seat. Driving members are provided in both the first clamping rod and the second clamping rod, and the driving members are used to drive the first clamping rod or the second clamping rod to approach or move away from each other. The second clamping member has the same structure as the first clamping member and includes a third clamping rod and a fourth clamping rod.

[0020] Preferably, buffer blocks are provided at the tops of both the third clamping rod and the fourth clamping rod. The buffer blocks are made of flexible materials, and the tops of the buffer blocks are of inclined surface structures.

[0021] Its effect is that: setting the buffer blocks can prevent the impact generated when the drill rod falls on the third clamping rod and the fourth clamping rod from damaging the drill rod.

[0022] Preferably, a limiting protrusion is further provided on the side wall of the third clamping rod, and the limiting protrusion can abut against the positioning surface of the drill rod.

[0023] Preferably, a blanking box is further provided at the bottom of the frame. A limiting plate is provided at the top of the blanking box, and the limiting plate is connected to the blanking box through a second elastic member. A buffer plate is provided in the blanking box, and the buffer plate is connected to the blanking box through a second elastic member.

[0024] Preferably, an aggregate box is further provided beside the blanking box. The top of the buffer plate is of an inclined surface structure, and the end close to the aggregate box is lower than the end far from the aggregate box.

[0025] Adopting the above technical solutions, the beneficial effects of the present invention are as follows:

[0026] Beneficial effects: For the drill rod drilling device according to the present invention, the lifting plates are located at the bottom of the frame. The conveyor belt transports the drill rod to be drilled onto the lifting plates, and the lifting plates are driven by the lifting mechanism to move upward until the lifting plates move to the uppermost end. The positioning seat moves forward, and the inclined blocks gradually approach the rear end of the drill rod until the inclined blocks extend into between the drill rod and the lifting plates. Under the push of the inclined blocks, the rear end of the drill rod is lifted upward. At this time, the front end of the drill rod can abut against the limiting block, and the limiting block prevents the drill rod from moving forward. When the center of gravity of the drill rod is behind the inclined block, the rear end of the drill rod falls on the second clamping member. At this time, the first clamping member and the second clamping member can clamp the drill rod to realize the positioning of the drill rod. The positioning seat moves backward until the drill rod abuts against the drilling mechanism, and at this time, the drill rod can be drilled.

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.

[0037] As Figures 1 to 3As shown in the figure, the feeding component 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. A plurality of baffles are provided on the conveyor belt 31, 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. A lifting mechanism is provided on the frame 1. The lifting mechanism includes a transmission chain and a driving motor. The transmission chain is rotationally matched with the frame 1. The driving motor is fixedly connected to the bottom of the frame 1, and its output end is engaged with the transmission chain.

A positioning block 321 is also provided on the lifting plate 32, and an arc-shaped groove is provided on the positioning block 321. The drill rod can be placed in the arc-shaped groove, so as to prevent the drill rod from rolling on the lifting plate 32. A limiting block 6 is also provided at the front end of the frame 1. A pushing plate 7 is provided on the limiting block 6. The pushing plate 7 is elastically connected to the limiting block 6 through a first elastic member, and the first elastic member is a spring.

[0038] As Figure 1 , Figure 2 and Figure 4 shown in the figure, a slide rail is provided on the frame 1. The positioning seat 33 is slidably matched with the slide rail. A driving unit is provided in the positioning seat 33. 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. 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 thereof. The first clamping member 4 includes a first clamping rod and a second clamping rod. Both the first clamping rod and the second clamping rod are slidably matched with the positioning seat 33. Driving members are provided in both the first clamping rod and the second clamping rod. The driving members are cylinders, which are used to drive the first clamping rods to approach or separate from each other. The second clamping member 5 has the same structure as the first clamping member 4. It includes a third clamping rod 51 and a fourth clamping rod 52. Buffer blocks 8 are also provided at the tops of the third clamping rod 51 and the fourth clamping rod 52. The buffer blocks 8 are made of rubber. The top of the buffer block 8 is a bevel end. The two buffer blocks 8 are symmetrically distributed left and right, and a V-shaped groove is formed between the two buffer blocks 8. A limiting protrusion 511 is provided on the side wall of the third clamping rod 51 close to the fourth clamping rod 52.

[0039] As Figure 1 and Figure 5As shown, a blanking box 9 is also provided at the bottom of the frame 1. The front end of the blanking box 9 abuts against and is slidably engaged with the lifting plate 32. A limiting plate 10 is provided at the top of the blanking box 9. The limiting plate 10 is elastically connected to the blanking box 9 through a second elastic member. The second elastic member is a spring. The top end of the limiting plate 10 can abut against the positioning seat 33. The top end of the limiting plate 10 is of a double-bevel structure. When the positioning seat 33 moves to contact the limiting plate 10, it can move along the inclined surface of the limiting plate 10 and squeeze the limiting plate 10 downward. A buffer plate 11 is also provided in the blanking box 9. The buffer plate 11 is elastically connected to the bottom end of the blanking box 9 through a third elastic member. The third elastic member is a spring. An aggregate box 12 is also provided on the left side of the blanking box 9. The aggregate box 12 is communicated with the blanking box 9. The top surface of the buffer plate 11 is of an inclined surface structure, and its left end is lower than its right end.

[0040] According to the drill rod drilling device of the present invention, the lifting plate 32 is located at the bottom of the frame 1. The conveyor belt transports the drill rod to be drilled onto 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. At this time, the front end of the drill rod can abut against the limiting block 6, and the limiting block 6 prevents the drill rod from moving forward. When the center of gravity of the drill rod is located behind the inclined surface block 331, the rear end of the drill rod falls on the buffer blocks 8 at the tops of the third clamping rod 51 and the fourth clamping rod 52 and slides downward along the V-shaped groove formed between the two buffer blocks 8. When the positioning surface on its side wall fits with the limiting protrusion 511, the rear end of the drill rod can slide downward 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 frontmost end, the front end of the positioning seat 33 abuts 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 protruding out of the positioning seat 33. The positioning seat 33 moves backward until its rear end abuts against the positioning table 21. At this time, the positioning surface at the rear end of the drill rod abuts against the positioning flange on the positioning table 21. The driving member drives the first clamping rod, the second clamping rod, the third clamping rod 51 and the fourth clamping rod 52 to approach each other, so as to tightly clamp the drill rod and realize the fixation of the drill rod. Subsequently, the drill rod 23 drills the drill rod.

[0041] After the drilling is completed, the first clamping member 4 and the second clamping member 5 release the drill rod that has completed drilling. The positioning seat 33 moves forward. At this time, the lifting plate 32 lifts the next drill rod to be drilled upward. During the forward movement of the positioning seat 33, the positioning seat 33 will cross the limit plate 10. The rear end of the drill rod to be processed abuts against the front end of the processed drill rod, and pushes the front end of the processed drill rod to lift. The processed drill rod tilts out of the positioning seat 33 from the rear end of the positioning seat 33 and slides down along the limit plate 10, and finally lands on the buffer plate 11. Under the gravity of the processed drill rod, the buffer plate 11 moves downward to prevent the processed drill rod from hindering the backward movement of the positioning seat 33. The processed drill rod moves along the inclined surface of the buffer plate 11 into the aggregate box 12, realizing automatic blanking.
