Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline laying and drilling holes, in particular to a pipeline laying and drilling hole device. Background Art

[0002] There are two ways to lay pipelines, either burying the pipeline directly in the soil (direct burial), or digging a trench in the ground, placing the pipeline in it and then covering the trench (trench laying). Before laying the pipeline, holes are drilled in the ground where the pipeline is to be laid. The purpose of drilling holes is to provide enough space to install and lay the pipeline. By drilling holes, a channel or trench suitable for laying the pipeline can be created.

[0003] In the prior art, a rotary drilling technique is usually used to drill holes in the ground, that is, a motor provides operating power to it, which is transmitted to a power head to rotate a drill bit mounted on a drill rod to break the ground, and then the drill bit is lifted out of the hole by a lifting device and a telescopic drill rod. This process is repeated until the designed drilling depth is reached.

[0004] During long-term use and observation, it was found that during the drilling process of the drilling rig, the soil knocked out during drilling tends to accumulate at the hole mouth, causing the drill bit to be inaccurately positioned or difficult to enter the hole when drilling holes in the ground where pipelines need to be laid.

[0005] To this end, the utility model provides a pipeline laying drilling device. Utility Model Content

[0006] In order to make up for the deficiencies of the prior art and solve at least one problem raised in the background technology, a pipeline laying drilling device is proposed.

[0007] The technical solution adopted by the utility model to solve its technical problems is as follows: a pipeline laying drilling device described in the utility model comprises a fixed seat; a motor is arranged on the top of the fixed seat; a rotating seat is fixedly connected to the output end of the motor; a first fixed rod is fixedly connected to the bottom of the rotating seat; a conical auger is fixedly connected to the middle of the side wall of the first fixed rod; a drilling head is fixedly connected to the end of the first fixed rod; a blocking cover is rotatably connected to the middle of the side wall of the first fixed rod; a support frame is rotatably connected to the middle of the inner wall of the blocking cover; the support frames are multiple and evenly arranged on the inner wall of the blocking cover; the support frames The end is rotatably connected to a first slip ring; the first slip ring slides in the middle of the side wall of the first fixed rod; the blocking cover, the support frame and the first slip ring are all arranged above the conical auger; this step can block the soil produced by the conical auger and the drill head when drilling holes in the ground where pipes need to be laid outside the hole by arranging the blocking cover, the support frame and the first slip ring, effectively reducing the accumulation of soil produced by the conical auger and the drill head when drilling holes at the hole mouth, thereby hindering the entry and operation of the conical auger and the drill head when drilling holes in the ground where pipes need to be laid, resulting in reduced drilling work efficiency.

[0008] Preferably, a second fixing rod is fixedly connected to the middle part of the side wall of the first fixing rod; the second fixing rod is arranged between the conical auger and the drilling head; a claw-shaped blade is fixedly connected to the middle part of the bottom of the second fixing rod; the claw-shaped blades are multiple and are regularly arranged in a circular array at the bottom of the second fixing rod; the claw-shaped blades are made of high-hardness material; in this step, by arranging the claw-shaped blades, the ground around the drilling head can be broken while the drilling head is drilling a hole in the ground where the pipeline needs to be laid, so that the subsequent conical auger can be driven into the ground more easily, which can reduce the situation where the conical auger fails or is shut down for maintenance due to the hard ground that is difficult to break, and at the same time improves the work efficiency so that the drilling work can be completed efficiently and quickly.

[0009] Preferably, a water storage bag is fixedly connected to the middle of the side wall of the first fixing rod; the water storage bag is arranged above the conical auger; water outlets are opened at the top and bottom of the water storage bag; the water outlets are multiple and are correspondingly arranged at the top and bottom of the water storage bag; multiple first connecting ropes are fixedly connected to the bottom of the first slip ring; the first connecting rope is made of elastic material; multiple sealing covers are fixedly connected to the middle of the first connecting rope; the sealing covers and the water outlets are correspondingly arranged; a hose water injection port is fixedly connected to the middle of the outer wall of the water storage bag; the hose water injection port is made of elastic material; this step sets the water storage bag, the water outlet, the first connecting rope Rope, sealing cover and hose water injection port. When the conical auger and the drilling head are drilling holes in the ground where pipes need to be laid, the water injected into the water storage bag can flow along the outer wall of the conical auger to the ground through this arrangement, thereby wetting the ground where holes need to be drilled. The moist ground helps to reduce the temperature generated by the conical auger and the drilling head during the drilling process, thereby preventing the conical auger and the drilling head from overheating and being damaged. At the same time, for harder ground, wetting can soften it and make it easier to be penetrated by the conical auger and the drilling head, which can reduce the wear of the conical auger and the drilling head and further improve the drilling efficiency.

[0010] Preferably, a first spring is fixedly connected to the bottom of the rotating seat; a support shaft is provided in the middle of the first spring; there are multiple first springs and they are regularly arranged in a circular array at the bottom of the rotating seat; a second slip ring is fixedly connected to the end of the first spring; the second slip ring slides in the middle of the side wall of the first fixed rod; a brush is fixedly connected to the bottom of the second slip ring; there are multiple brushes and they are regularly arranged in a circular array at the bottom of the second slip ring; multiple second connecting ropes are fixedly connected to the side wall of the second slip ring; the end of the second connecting rope is fixedly connected to the outer wall of the blocking cover; the second connecting rope is made of elastic material; in this step, by arranging the first spring, the second slip ring, the brush and the second connecting rope, during the winding and unfolding process of the blocking cover, the second slip ring will move up and down in the middle of the first fixed rod and the outer wall of the blocking cover, so that the brush at the bottom of the second slip ring can clean the dirt remaining on the surface of the blocking cover, because the hair material of the brush has a certain hardness, which can effectively clean the dirt on the surface of the blocking cover, reducing the blocking cover from being unfolded and wound due to excessive dirt remaining on the surface of the blocking cover during drilling operation, resulting in the situation that the dirt cannot be quickly blocked from accumulating at the hole mouth during the next drilling operation.

[0011] Preferably, a protective cover is fixedly connected to the bottom of the second fixing rod; a second spring is fixedly connected to the middle of the outer wall of the protective cover; the other end of the second spring is fixedly connected to the outer wall of the second fixing rod; a support shaft is provided in the middle of the second spring; in this step, by providing the protective cover and the second spring, the soil splashed when the drill head drills a hole can be restricted inside the protective cover, thereby reducing the physical harm caused to the workers by the splashed soil. At the same time, the splashed soil may cause the drilling rig to be contaminated and damaged. By providing the protective cover, the soil can be prevented from damaging the drilling rig and its service life can be extended.

[0012] Preferably, a crushing blade is fixedly connected to the bottom of the claw-shaped blade; the crushing blades are multiple and evenly arranged at the bottom of the claw-shaped blade; this step can improve the breaking strength of the claw-shaped blade on the ground around the drilling head by arranging the crushing blade, further reduce the situation where the conical auger fails or is shut down for maintenance due to the hard ground being difficult to break, further improve the work efficiency so that the drilling work can be completed efficiently and quickly.

[0013] The beneficial effects of the utility model are as follows:

[0014] 1.

[0015] 2. The utility model describes a pipeline laying drilling device, through which the water injected into the water storage bag flows along the outer wall of the conical auger to the ground, thereby wetting the ground to be drilled. The moist ground helps to reduce the temperature generated by the conical auger and the drilling head during the drilling process, thereby preventing the conical auger and the drilling head from overheating and being damaged. At the same time, for relatively hard ground, wetting can soften it and make it easier to be penetrated by the conical auger and the drilling head, which can reduce the wear of the conical auger and the drilling head and further improve the drilling efficiency.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Specific examples are given below.

[0026] like Figures 1 to 4As shown, a pipeline laying drilling device described in an embodiment of the utility model comprises a fixed seat 1; a motor 11 is provided on the top of the fixed seat 1; a rotating seat 12 is fixedly connected to the output end of the motor 11; a first fixed rod 13 is fixedly connected to the bottom of the rotating seat 12; a conical auger 14 is fixedly connected to the middle of the side wall of the first fixed rod 13; a drilling head 15 is fixedly connected to the end of the first fixed rod 13; a blocking cover 16 is rotatably connected to the middle of the side wall of the first fixed rod 13; a support frame 17 is rotatably connected to the middle of the inner wall of the blocking cover 16; the support frame 17 is a plurality of And evenly arranged on the inner wall of the blocking cover 16; the end of the support frame 17 is rotatably connected to the first slip ring 18; the first slip ring 18 slides in the middle of the side wall of the first fixed rod 13; the blocking cover 16, the support frame 17 and the first slip ring 18 are all arranged above the conical auger 14; when working, the staff uses a crane to lift the fixed seat 1, and then turns on the motor 11, the motor 11 drives the output end rotating seat 12 to rotate, and the rotating seat 12 rotates while driving the first fixed rod 13 fixed at the bottom to rotate, at this time, the conical auger 14 fixed to the middle of the first fixed rod 13 The cone auger 14 and the drilling head 15 rotate synchronously with the rotation of the first fixing rod 13. The rotating cone auger 14 and the drilling head 15 will drill holes in the ground where the pipeline needs to be laid. When the cone auger 14 is completely immersed in the ground, the first slip ring 18 is pushed upward. At this time, the support frame 17 is opened outward under the drive of the first slip ring 18, and the blocking cover 16 rotatably connected to the support frame 17 is also unfolded outward. When the drilling operation on the ground where the pipeline needs to be laid is completed, the cone auger 14 and the drilling head 15 will be pulled outward, and then the first slip ring 18 will be pushed downward. Driven by the support frame 17 and the first slip ring 18, the blocking cover 16 shrinks and returns to its original state. In this step, by setting the blocking cover 16, the support frame 17 and the first slip ring 18, the soil driven out by the conical auger 14 and the drilling head 15 when drilling a hole in the ground where the pipeline needs to be laid can be blocked outside the hole, effectively reducing the situation in which the soil driven out by the conical auger 14 and the drilling head 15 when drilling a hole accumulates at the hole mouth, thereby hindering the conical auger 14 and the drilling head 15 from entering and operating when drilling a hole in the ground where the pipeline needs to be laid, resulting in reduced drilling efficiency.

[0027] Further, such as Figure 1 , Figure 2 and Figure 5As shown, a second fixing rod 2 is fixedly connected to the middle of the side wall of the first fixing rod 13; the second fixing rod 2 is arranged between the conical auger 14 and the drilling head 15; a claw-shaped blade 21 is fixedly connected to the middle of the bottom of the second fixing rod 2; the claw-shaped blades 21 are multiple and are regularly arranged in a circular array at the bottom of the second fixing rod 2; the claw-shaped blades 21 are made of high hardness material; when working, the staff turns on the motor 11, the motor 11 drives the rotating seat 12 to rotate, and the rotating seat 12 rotates while driving the first fixing rod 13 to rotate, at this time, the conical auger 14 and the drilling head 15 fixed to the middle of the first fixing rod 13 start to move the hole to be paved as the first fixing rod 13 rotates. The drilling operation is performed on the ground where the pipeline is to be laid. When the drilling head 15 drills a hole in the ground, the claw blade 21 will come into contact with the ground during the descent. Because the claw blade 21 is made of a high-hardness material, the claw blade 21 will break the ground around the drilling head 15 during rotation. In this step, by setting the claw blade 21, the ground around the drilling head 15 can be broken while the drilling head 15 is drilling a hole in the ground where the pipeline needs to be laid, so that the subsequent conical auger 14 can be driven into the ground more easily, which can reduce the situation where the conical auger 14 malfunctions or shutdowns for maintenance due to the hard ground being difficult to break, and at the same time improves the work efficiency so that the drilling work can be completed efficiently and quickly.

[0028] Further, such as Figure 1 , Figure 2 and Figure 4As shown, a water storage bag 3 is fixedly connected to the middle of the side wall of the first fixing rod 13; the water storage bag 3 is arranged above the conical auger 14; a water outlet 31 is opened at the top and bottom of the water storage bag 3; the water outlet 31 is multiple and is correspondingly arranged at the top and bottom of the water storage bag 3; a plurality of first connecting ropes 32 are fixedly connected to the bottom of the first sliding ring 18; the first connecting rope 32 is made of elastic material; a plurality of sealing covers 33 are fixedly connected to the middle of the first connecting rope 32; the sealing covers 33 are arranged correspondingly to the water outlet 31; the outer wall of the water storage bag 3 is The bottom of the water storage bag 3 is fixedly connected with a hose water injection port 34; the hose water injection port 34 is made of elastic material; when working, when the drilling rig is in place and about to start drilling, the first slip ring 18 falls in place, and the blocking cover 16 is in a reeled state. Because the sealing cover 33 is corresponding to the water outlets 31 opened at the top and bottom of the water storage bag 3, the sealing cover 33 completely blocks the water outlets 31. Then the staff injects water into the water storage bag 3 from the hose water injection port 34. When the motor 11 is started, the conical auger 14 and the drilling head 15 start to drill the ground where the pipeline needs to be laid. When drilling a hole, the first sliding ring 18 is pushed upward, driving the first connecting rope 32 to move upward. At this time, the first connecting rope 32 will pull the sealing cover 33 upward and pull it out until the sealing cover 33 is separated from the inside of the water storage bag 3. At this time, the water inside the water storage bag 3 will drip along the water outlet 31 at the bottom of the water storage bag 3 and the surface of the conical auger 14 to the ground where the pipeline needs to be laid. This step sets the water storage bag 3, the water outlet 31, the first connecting rope 32, the sealing cover 33 and the hose water injection port 34. When the conical auger 14 and the drilling head 15 are used to drill the ground where the pipeline needs to be laid, When drilling a hole, this arrangement can be used to allow the water injected into the water storage bag 3 to flow along the outer wall of the conical auger 14 toward the ground, thereby wetting the ground to be drilled. The moist ground helps to reduce the temperature generated by the conical auger 14 and the drilling head 15 during the drilling process, thereby preventing the conical auger 14 and the drilling head 15 from overheating and being damaged. At the same time, for relatively hard ground, wetting can soften it and make it easier to be penetrated by the conical auger 14 and the drilling head 15, which can reduce the wear of the conical auger 14 and the drilling head 15 and further improve the drilling efficiency.

[0029] Further, such as Figures 1 to 3As shown, a first spring 4 is fixedly connected to the bottom of the rotating seat 12; a supporting shaft is provided in the middle of the first spring 4; there are multiple first springs 4 and they are regularly arranged in a circular array at the bottom of the rotating seat 12; a second slip ring 41 is fixedly connected to the end of the first spring 4; the second slip ring 41 slides in the middle of the side wall of the first fixed rod 13; a brush 42 is fixedly connected to the bottom of the second slip ring 41; there are multiple brushes 42 and they are regularly arranged in a circular array at the bottom of the second slip ring 41; a plurality of second connecting ropes 43 are fixedly connected to the side wall of the second slip ring 41; the end of the second connecting rope 43 is fixedly connected to the outer wall of the blocking cover 16; the second connecting rope 43 is made of elastic material; during operation, when the drilling rig is in place and is about to start drilling, the first slip ring 18 falls into place, and the blocking cover 16 is in a reeled state. Under the reeling and pulling of the blocking cover 16, the multiple second connecting ropes 43 fixedly connected to the outer wall of the blocking cover 16 will pull the second The slip ring 41 is pulled to pull the second slip ring 41 downward, so that the second slip ring 41 passes through the retracted surface of the blocking cover 16. At this time, multiple brushes 42 fixed to the bottom of the second slip ring 41 clean the surface of the blocking cover 16. This step is achieved by setting the first spring 4, the second slip ring 41, the brush 42 and the second connecting rope 43. During the winding and unfolding process of the blocking cover 16, the second slip ring 41 will move up and down between the middle of the first fixed rod 13 and the outer wall of the blocking cover 16, so that the brush 42 at the bottom of the second slip ring 41 can clean the dirt remaining on the surface of the blocking cover 16. Because the hair material of the brush 42 has a certain hardness, it can effectively clean the dirt on the surface of the blocking cover 16, reducing the blocking cover 16 unfolding and winding action jamming due to excessive dirt remaining on the surface of the blocking cover 16 during drilling operations, resulting in the next drilling operation. The situation where the dirt cannot be quickly blocked from accumulating at the hole mouth.

[0030] Further, such as Figure 1 , Figure 2 and Figure 5As shown, a protective cover 5 is fixedly connected to the bottom of the second fixing rod 2; a second spring 51 is fixedly connected to the middle of the outer wall of the protective cover 5; the other end of the second spring 51 is fixedly connected to the outer wall of the second fixing rod 2; a supporting shaft is provided in the middle of the second spring 51; during operation, when the drilling head 15 drills a hole to break the ground where the pipeline needs to be laid, the protective cover 5 can block the soil splashed out during the drilling inside the protective cover 5. When the drilling head 15 is completely immersed in the ground, the ground will give the protective cover 5 a thrust, so that the protective cover 5 flips up backwards and is pressed against the surface of the second fixing rod 2. When the drilling head 15 is pulled out of the ground, the protective cover 5 returns to its original state under the rebound of the second spring 51. In this step, by setting the protective cover 5 and the second spring 51, the soil splashed when the drilling head 15 drills a hole can be limited to the inside of the protective cover 5, thereby reducing the situation where the splashed soil causes physical harm to the staff. At the same time, the splashed soil may cause the drilling rig to be contaminated and damaged. By setting the protective cover 5, the soil can be prevented from causing damage to the drilling rig and its service life can be extended.

[0031] Further, such as Figure 1 , Figure 2 and Figure 5 As shown, a crushing blade 6 is fixedly connected to the bottom of the claw-shaped blade 21; the crushing blade 6 is multiple and evenly arranged at the bottom of the claw-shaped blade 21; this step can improve the breaking strength of the claw-shaped blade 21 on the ground around the drilling head 15 by setting the crushing blade 6, further reduce the situation of the conical auger 14 malfunctioning or shutting down for maintenance due to the hard ground being difficult to break, further improve the work efficiency so that the drilling work can be completed efficiently and quickly.

[0032] Working principle: the staff uses a crane to lift the fixed seat 1, and then turns on the motor 11. The motor 11 drives the output end rotating seat 12 to rotate. The rotating seat 12 drives the first fixed rod 13 fixed to the bottom to rotate at the same time. At this time, the conical auger 14 and the drilling head 15 fixed to the middle of the first fixed rod 13 rotate synchronously with the rotation of the first fixed rod 13. The rotating conical auger 14 and the drilling head 15 will drill holes on the ground where pipes need to be laid. When the conical auger 14 is completely immersed in the ground, it pushes the first slip ring 18 upward. At this time, the support frame 17 is opened outward under the drive of the first slip ring 18, and the blocking cover 16 rotatably connected to the support frame 17 is also expanded outward. When the drilling operation on the ground where pipes need to be laid is completed, The conical auger 14 and the drilling head 15 are pulled outward, and then the first slip ring 18 is pushed downward. Driven by the support frame 17 and the first slip ring 18, the blocking cover 16 shrinks and returns to its original state. The staff turns on the motor 11, and the motor 11 drives the rotating seat 12 to rotate. The rotating seat 12 drives the first fixed rod 13 to rotate while rotating. At this time, the conical auger 14 and the drilling head 15 fixed to the middle of the first fixed rod 13 start to drill holes in the ground where pipes need to be laid as the first fixed rod 13 rotates. When the drilling head 15 drills a hole in the ground, the claw blade 21 will contact the ground during the descent. Because the claw blade 21 is made of high hardness material, the claw blade 21 will break the ground around the drilling head 15 during rotation. When the drilling rig When the drilling operation is about to begin, the first slip ring 18 falls into place and the blocking cover 16 is in a reeled state. Because the sealing cover 33 is corresponding to the water outlets 31 opened at the top and bottom of the water storage bag 3, the sealing cover 33 completely blocks the water outlet 31. Then the staff injects water into the water storage bag 3 from the hose water inlet 34. When the motor 11 is started, the conical auger 14 and the drilling head 15 start to drill holes in the ground where pipes need to be laid, the first slip ring 18 is pushed upward, driving the first connecting rope 32 to move upward. At this time, the first connecting rope 32 will pull the sealing cover 33 upward and pull it out until the sealing cover 33 is detached from the water storage bag 3. At this time, the water in the water storage bag 3 will flow along the water outlet 31 at the bottom of the water storage bag 3 and along the surface of the conical auger 14 The first slip ring 18 is dripped into the ground where the pipeline needs to be laid. When the drilling rig is in place and is about to start drilling, the first slip ring 18 falls into place and the blocking cover 16 is in a reeled state. Under the reeling pull of the blocking cover 16, multiple second connecting ropes 43 fixed to the outer wall of the blocking cover 16 will pull the second slip ring 41, and pull the second slip ring 41 downward, so that the second slip ring 41 passes through the retracted surface of the blocking cover 16. At this time, multiple brushes 42 fixed to the bottom of the second slip ring 41 clean the surface of the blocking cover 16. When the drilling head 15 drills a hole to break the ground where the pipeline needs to be laid, the protective cover 5 can block the soil splashed during drilling inside the protective cover 5. When the drilling head 15 is completely immersed in the ground, the ground will give the protective cover 5 a thrust.The protective cover 5 is flipped back and pressed against the surface of the second fixing rod 2. When the drilling head 15 is pulled out from the ground, the protective cover 5 returns to its original state under the rebound of the second spring 51.
