Abstract
Description
Technical Field
[0001] This invention relates to the field of steel pipe drilling technology, specifically to a steel pipe drilling device for building construction. Background Technology
[0002] In construction engineering, steel pipes are commonly used as a core material for building various frames and supports. These steel pipes require precise drilling to ensure proper connection and integration with other components. Traditional drilling methods are typically labor-intensive, slow, and lack precision, thus affecting construction safety and efficiency.
[0003] A search revealed a Chinese patent with publication number CN113305580B, which includes a housing. A vertical telescopic mechanism is mounted on the inner top surface of the housing. A rotating mechanism is mounted at the lower end of the vertical telescopic mechanism. A multi-functional drilling mechanism is vertically mounted below the rotating mechanism. The rotating mechanism is used to drive the multi-functional drilling mechanism to rotate. A moving mechanism is mounted on the inner bottom surface of the housing. A clamping mechanism is mounted above the moving mechanism. The clamping mechanism is used to clamp the steel pipe. The multi-functional drilling mechanism is used to drill various different holes in the steel pipe. A controller is mounted on the housing. The controller is connected to the vertical telescopic mechanism, the rotating mechanism, the moving mechanism, the clamping mechanism, and the multi-functional drilling mechanism.
[0004] The aforementioned patent is controlled by a controller, has a simple structure, is easy to use, and can be used to process various different round holes. It can also be used to remove burrs from the inner and outer edges of round holes to prevent burrs from scratching the user's hands. In addition, when processing stepped holes, the aforementioned patent can prevent the stepped holes from deforming.
[0005] However, the aforementioned patent lacks a positioning function for the steel pipe. When performing multiple drilling operations, it is necessary to repeatedly adjust the steel pipe manually to determine the drilling position. The operation steps are cumbersome and prone to human error, which leads to a decrease in drilling accuracy. On the other hand, the aforementioned patent is only applicable to vertical drilling operations on rectangular tubes. When drilling at multiple angles, the clamping process of the clamping mechanism on the steel pipe may cause the steel pipe to deflect at a small angle under the impact force during drilling, thus causing drilling failure.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention. Example 1:
[0033] Please see Figures 1 to 9 This invention provides a technical solution: a steel pipe drilling device for construction engineering, comprising a fixed plate 1 and two sets of lifting mechanisms arranged on the front and rear sides of the upper surface of the fixed plate 1, two sets of traveling components arranged on the horizontal sides of the fixed plate 1, and two sets of deflection mechanisms arranged on the front and rear sides below the fixed plate 1. The device is characterized in that: support shafts 11 are fixedly connected to both horizontal sides of the lower surface of the fixed plate 1, and fixed frames 12 are fixedly connected to the bottom ends of the two support shafts 11. An inverted T-shaped groove is opened inside the fixed frame 12. A lifting block 14 is vertically penetrating and arranged inside the fixed plate 1. Multiple sets of symmetrically arranged vertical guide rails 13 are fixedly connected to the inner contour of both horizontal sides of the fixed plate 1, and the fixed plate 1 and the lifting block 14 are slidably connected through the vertical guide rails 13. A drill rig 15 driven by a motor is vertically penetrating and rotatably connected to the center of the lifting block 14.
[0034] The lifting mechanism includes fixed seats 2 that are fixedly connected to the front and rear sides of the upper surface of the fixed plate 1;
[0035] The traveling component includes a clamping mechanism for completing the steel pipe transmission work, a swinging mechanism for driving the steel pipe to move, and an adjustment mechanism for controlling the single travel amount of the steel pipe. The clamping mechanism includes a crown gear 3 that is connected to the lifting mechanism for transmission, and the swinging mechanism includes a support column 4 set on the outer contour of the fixed frame 12.
[0036] The deflection mechanism includes an adjusting shaft 6 for intermittent clamping of the steel pipe, the adjusting shaft 6 being connected through and rotatably limited to the front and rear sides of the lower surface of the fixed plate 1.
[0037] In this device, the fixed plate 1, the support shaft 11, and the fixed frame 12 are used as the frame structure to support the other mechanisms and achieve their transmission effect. The lifting mechanism drives the lifting block 14 and the drilling machine 15 to reciprocate to complete the drilling operation of the drilling machine 15. The maximum drilling depth of the drilling machine 15 can be adjusted by controlling the maximum lifting amount of the lifting mechanism. The vertical guide rail 13 limits the movement direction of the lifting block 14 to ensure that the lifting block 14 can only complete the vertical lifting movement, thereby avoiding the lifting block 14 and the drilling machine 15 from deflecting and causing the drilling operation to fail.
[0038] On the other hand, the lifting mechanism synchronously controls the operation of the clamping mechanism, which realizes intermittent clamping operation on the steel pipe. Specifically, when the lifting mechanism rises, the clamping mechanism extends and clamps the steel pipe, and when the lifting mechanism descends, the clamping mechanism retracts and releases the clamp on the steel pipe.
[0039] At the same time, the clamping mechanism intermittently controls the swing mechanism. While the swing mechanism swings back and forth, it drives the clamping mechanism to move horizontally back and forth synchronously under the limiting action of the fixed frame 12. Specifically, when the clamping mechanism clamps the steel pipe, the swing mechanism drives the clamping mechanism to complete the horizontal movement on one side. When the clamping mechanism relaxes, the swing mechanism drives the clamping mechanism to return to the initial position, thereby completing the intermittent pushing and moving operation of the steel pipe.
[0040] It should be noted that the maximum swing amount of the swing mechanism can be adjusted by controlling the adjustment mechanism, thereby further affecting the single travel amount of the steel pipe through the clamping mechanism, and thus improving the automation level of the device.
[0041] Furthermore, the clamping mechanism synchronously drives the deflection mechanism. The deflection mechanism also performs intermittent clamping of the steel pipe, but with the opposite effect to the clamping mechanism. Specifically, when the clamping mechanism clamps the steel pipe, the deflection mechanism loosens its grip on the steel pipe, and when the clamping mechanism loosens its grip, the deflection mechanism clamps the steel pipe. This achieves full-process clamping and fixation of the steel pipe while maintaining the movement between the clamping mechanism and the deflection mechanism without interference. Thus, when drilling the steel pipe, the clamping of the steel pipe by the deflection mechanism can effectively prevent the steel pipe from vibrating and causing drilling failure. After drilling is completed, the clamping mechanism can smoothly drive the steel pipe to move horizontally, thereby ensuring the operating efficiency and work quality of the device.
[0042] It should be noted that by controlling the adjusting shaft 6, the rotation angle of the steel pipe can be adjusted via the deflection mechanism, thereby fulfilling the functional requirement of multi-angle drilling of the steel pipe. Example 2:
[0043] Please see Figure 4 This embodiment further illustrates the following based on Embodiment 1: The fixed base 2 is rotatably connected to a drive shaft 21 that passes through it from front to back. A transmission wheel 22 is fixedly connected to the end of the drive shaft 21 away from the fixed disk 1. A telescopic linkage group 23 is fixedly connected to the end of the drive shaft 21 pointing towards the fixed disk 1. The other end of the telescopic linkage group 23 is rotatably connected to the front and rear sides of the lifting block 14 through it. The bottom end of the transmission wheel 22 is engaged and connected to a transmission gear ring 24 that is rotatably connected to the outer contour of the fixed disk 1.
[0044] The fixed base 2 is equipped with a motor, which controls the drive shaft 21 to rotate. When the motor is turned on, the drive shaft 21 drives the transmission wheel 22 and the transmission gear ring 24 to rotate synchronously. At the same time, the telescopic linkage group 23 rotates and, under the limiting action of the vertical guide rail 13, realizes the lifting operation of the lifting block 14 and the drilling machine 15. Specifically, when the telescopic linkage group 23 rotates, it synchronously undergoes folding and extending state changes. The synchronous lifting movement of the lifting block 14 and the drilling machine 15 realizes the drilling operation of the steel pipe.
[0045] It should be noted that when the drive shaft 21 rotates one revolution, the telescopic linkage 23 rotates 360° synchronously. During this process, the telescopic linkage 23 passes through two horizontal and vertical positions. When the telescopic linkage 23 is in the horizontal position, it reaches its maximum folding degree, and the lifting block 14 and the drilling rig 15 are at the same horizontal height as the transmission gear ring 24. At this time, the lifting block 14 and the drilling rig 15 reach the middle of their lifting stroke. When the telescopic linkage 23 is at the lowest or highest point of the vertical position, it reaches its maximum extension degree. At this time, the lifting block 14 and the drilling rig 15 are synchronously at the highest or lowest point of their lifting stroke. That is, during the process of the telescopic linkage 23 rotating one revolution with the drive shaft 21, there are two changes in the state of folding and extension. The lifting block 14 and the drilling rig 15 synchronously complete one reciprocating lifting operation. This process corresponds to the drilling rig 15 completing one drilling and resetting operation on the steel pipe.
[0046] by Figure 4 For example, the telescopic linkage 23 is initially in a horizontal position to the right of the drive shaft 21. At this time, the lifting block 14 and the drilling rig 15 are in the middle of their stroke. As the drive shaft 21 rotates clockwise, the telescopic linkage 23 rotates synchronously and unfolds downwards. When the drive shaft 21 rotates 90°, the telescopic linkage 23 reaches its maximum extension, at which point the lifting block 14 and the drilling rig 15 are at the lowest point of their lifting stroke. Subsequently, the drive shaft 21 continues to rotate, and the telescopic linkage 23 begins to fold upwards. When the drive shaft 21 rotates 90° again, the telescopic linkage... Group 23 returns to its horizontally folded state and is located to the left of drive shaft 21. At this time, lifting block 14 and drilling rig 15 rise synchronously and return to the middle of their stroke. Further, drive shaft 21 rotates 90° again. During this process, telescopic linkage group 23 unfolds upward and drives lifting block 14 and drilling rig 15 to the highest point of their lifting stroke. Subsequently, drive shaft 21 rotates 90° further, telescopic linkage group 23 folds downward and returns to the horizontal state located to the right of drive shaft 21. Lifting block 14 and drilling rig 15 synchronously reset to the middle of their stroke.
[0047] It should be noted that by adjusting the telescopic length of the telescopic linkage 23 itself, its maximum extension can be controlled. The maximum extension of the telescopic linkage 23 further affects the lifting height of the lifting block 14 and the drilling rig 15. Specifically, the distance between the horizontal height position of the lifting block 14 and the lowest point of the drilling rig 15 is equal to the maximum extension of the telescopic linkage 23. Meanwhile, the distance between the horizontal height position of the transmission gear ring 24 and the highest or lowest point of the stroke of the lifting block 14 and the drilling rig 15 in the middle of the stroke is equal to half the length of the maximum extension of the telescopic linkage 23, thereby completing the adjustment of the maximum drilling depth of the drilling rig 15. Example 3:
[0048] Please see Figure 5 This embodiment further illustrates the following based on Embodiment 2: The crown gear 3 is meshed and driven by the transmission gear ring 24 on both horizontal sides. A paddle 31 is fixedly connected to the top of the crown gear 3. A downwardly extending threaded column 32 is fixedly connected to the shaft of the crown gear 3. An internal threaded sleeve 33 is reciprocally threaded to the bottom of the threaded column 32. The internal threaded sleeve 33 is slidably connected to the top of the fixed frame 12 through and with a limiting position. Herringbone teeth are provided on the outer contour of the top of the internal threaded sleeve 33. A pressing block 34 with a limiting position and sliding connection is fixedly connected to the bottom of the internal threaded sleeve 33 and is slidably connected to the inside of the inverted T-groove of the fixed frame 12. The end of the pressing block 34 away from the fixed frame 12 is set with a downward inclined surface, and a clamping plate 35 is drivenly connected to the inclined surface of the pressing block 34. A telescopic shaft 36 with a limiting position and horizontal sliding connection is fixedly connected to the end of the clamping plate 35 pointing towards the fixed frame 12 and is slidably connected to the inside of the inverted T-groove of the fixed frame 12. A return spring is provided inside the telescopic shaft 36.
[0049] Furthermore, as the transmission gear ring 24 rotates, it drives the crown gear 3 and the threaded column 32 to rotate synchronously. The threaded column 32 further tends to drive the inner threaded sleeve 33 to rotate. However, the inner threaded sleeve 33 cannot rotate due to its limiting sliding connection with the fixed frame 12, which causes the inner threaded sleeve 33 to achieve its own reciprocating lifting motion at the top of the fixed frame 12 under the action of the rotation of the threaded column 32.
[0050] The transmission ratio between the crown gear 3 and the fixed seat 2 is limited to one to one, and the transmission ratio between the reciprocating thread of the internal threaded sleeve 33 and the threaded column 32 is limited to one to two. That is, when the fixed seat 2 rotates one revolution, the crown gear 3 also rotates one revolution and the internal threaded sleeve 33 achieves one reciprocating lifting and lowering, thereby corresponding the lifting and lowering process of the internal threaded sleeve 33 with the lifting and lowering process of the drilling rig 15.
[0051] When the internal threaded sleeve 33 descends, it pushes the extrusion block 34 to descend synchronously along the vertical direction of the inverted T-slot of the fixed frame 12. At this time, the extrusion block 34 further extrudes the clamping plate 35, while the clamping plate 35 is restricted by the horizontal direction of the inverted T-slot of the fixed frame 12 and cannot descend. As a result, the clamping plate 35 is squeezed out towards the steel pipe and completes the clamping operation on the steel pipe. During this process, the clamping plate 35 pulls the telescopic shaft 36 to move synchronously, while the other end of the telescopic shaft 36 is limited by the swing mechanism, causing the telescopic shaft 36 to be stretched. The return spring inside is stretched synchronously.
[0052] When the internal threaded sleeve 33 rises, the pressing block 34 rises synchronously and releases the pressing on the fixed frame 12. At this time, the telescopic shaft 36 slowly retracts under the action of its internal return spring and drives the clamping plate 35 to move synchronously to release the clamping plate 35 from the steel pipe. Thus, during the rotation of the fixed seat 2, the clamping plate 35 achieves the clamping and releasing process of the steel pipe.
[0053] It should be noted that by setting the initial screw orientation between the reciprocating thread of the internal threaded sleeve 33 and the threaded post 32, the lifting and lowering movement of the internal threaded sleeve 33 is adjusted to first rise and then fall, that is, the clamping plate 35 first relaxes and then clamps the steel pipe. This process corresponds to the process of the drilling rig 15 first falling and then rising. That is, when the drilling rig 15 falls and realizes the drilling process of the steel pipe, the clamping plate 35 does not come into contact with the steel pipe. Then, during the process of the drilling rig 15 rising and resetting, the clamping plate 35 squeezes out and clamps the steel pipe. Example 4:
[0054] Please see Figure 6 This embodiment further illustrates the following based on Embodiment 3: The support column 4 is fixedly connected to the upper surface of the fixed frame 12 on the side away from the fixed plate 1. The top of the support column 4 is horizontally penetrated and rotatably connected to a transmission shaft 41. The end of the transmission shaft 41 located directly above the crown gear 3 is fixedly connected to a lever 42. The two ends of the lever 42 correspond to the front and rear sides of the upper surface of the crown gear 3 and are intermittently connected to the lever 31. The end of the transmission shaft 41 away from the crown gear 3 is fixedly connected to a transmission rod 43. The bottom end of the transmission rod 43 is fixedly connected to a limiting plate 48, and the surface of the limiting plate 48 is provided with a vertical groove for the telescopic shaft 36 to be limited, raised, lowered, and slidably connected.
[0055] A limiting frame 44 is fixedly connected to the bottom end of the transmission rod 43 away from the fixed frame 12. A slider 45 is slidably connected inside the limiting frame 44. A compression spring 46 is fixedly connected between the slider 45 and the inner contour of the top of the limiting frame 44. A swing rod 47 is connected through and rotatably to the end of the slider 45 away from the fixed frame 12.
[0056] The adjustment mechanism includes an extension plate 5 fixedly connected to the bottom outer surface of the fixed frame 12 away from the clamping plate 35. The extension plate 5 extends upward and is fixedly connected to a fixing block 51. The fixing block 51 is internally limited and slidably connected to a positioning block 53. The extension plate 5 is vertically penetrated and extends downward to a threaded shaft 52. The threaded shaft 52 is screwed to the positioning block 53. The end of the positioning block 53 away from the fixed frame 12 is penetrated and is limited and rotatably connected to the bottom end of the swing rod 47.
[0057] During the rotation of the crown gear 3, the paddle 31 rotates synchronously and continuously moves the lever 42 to deflect it to both sides. Figure 6 Taking the initial position of the paddle 31 as an example, at this time, the paddle 31 and the lever 42 are not in contact. When the paddle 31 rotates with the crown gear 3 to the left side of the lever 42, it contacts the lever 42 and squeezes the lever 42 to deflect clockwise by a small angle. Then the paddle 31 and the lever 42 separate again and continue to rotate with the crown gear 3. When the paddle 31 contacts the right side of the lever 42, the paddle 31 contacts the lever 42 again and squeezes, causing the lever 42 to deflect counterclockwise. Since the two ends of the lever 42 correspond to the front and rear sides of the crown gear 3, that is, during the process of the crown gear 3 rotating one revolution, the paddle 31 just pushes the lever 42 to deflect back and forth twice. Furthermore, the swinging deflection of the lever 42 drives the transmission shaft 41 and the transmission rod 43 to move synchronously, thereby realizing the reciprocating swing of the transmission rod 43 with the transmission shaft 41 as the axis.
[0058] Furthermore, the transmission rod 43 synchronously drives the limiting plate 48 to swing back and forth. At this time, the limiting plate 48 tends to drive the telescopic shaft 36 to swing synchronously. However, the telescopic shaft 36 is restricted by the horizontal direction of the inverted T-shaped groove of the fixed frame 12, so that the telescopic shaft 36 can only perform horizontal reciprocating motion. At the same time, the contact position between the vertical groove of the limiting plate 48 and the telescopic shaft 36 changes synchronously. The setting of the vertical groove on the limiting plate 48 eliminates the stress generated by the horizontal movement of the telescopic shaft 36 due to the swing of the limiting plate 48, thereby maintaining the stability of the structure. The telescopic shaft 36 further drives the clamping plate 35 to move synchronously. At this time, if the clamping plate 35 clamps the steel pipe, the horizontal movement of the clamping plate 35 drives the steel pipe to move. If the clamping plate 35 does not contact the steel pipe, the horizontal movement of the clamping plate 35 realizes its own reset.
[0059] It should be noted that one rotation of the crown gear 3 corresponds to one reciprocating swing of the limit plate 48, that is, one horizontal reciprocating movement of the clamping plate 35. Simultaneously, the clamping plate 35 clamps or loosens its grip on the steel pipe. The overall movement of the clamping plate 35 is as follows: during the first half-turn of the crown gear 3's rotation, the clamping plate 35 gradually loosens its grip on the steel pipe until it no longer contacts it. Then, the lever 31 actuates the lever 42 once, at which point the clamping plate 35 rapidly moves horizontally to its limit distance. This process corresponds to the downward drilling operation of the drilling rig 15. Subsequently, the crown gear... In the second half of the rotation of wheel 3, clamping plate 35 is gradually squeezed out and clamps the steel pipe. At this time, lever 31 moves lever 42 again, clamping plate 35 moves horizontally and resets. During this process, clamping plate 35 drives steel pipe to move synchronously to complete the intermittent pushing and moving operation of steel pipe. This process corresponds to the rising and resetting process of drilling rig 15 and the moving operation only begins when drilling rig 15 rises to near the highest point. This effectively avoids the drilling rig 15 failing to disengage from steel pipe in time during the moving process, thus effectively ensuring the stability of steel pipe moving operation.
[0060] Furthermore, during the swinging process of the transmission rod 43, the limiting frame 44 drives the upper ends of the slider 45 and the swing rod 47 to swing synchronously. However, the lower end of the swing rod 47 is restricted by the adjusting mechanism and cannot move horizontally. As a result, during the swinging process of the transmission rod 43, the swing rod 47 simultaneously exhibits reciprocating deflection to both sides. During this process, since the length of the swing rod 47 is fixed and its bottom position is fixed, the swing rod 47 will synchronously drive the slider 45 to change its position inside the limiting frame 44. At this time, the compression spring 46 is simultaneously compressed or released. During the swinging process of the transmission rod 43, in the first half of the stroke, it moves from an inclined state towards a vertical state in the middle section. At this time, the swing rod 47 moves from an inclined state towards a vertical state in the middle section, and the compression spring 46 is synchronously compressed. After the transmission rod 43 passes through the middle vertical position, the transmission rod 43 and the swing rod 47 tend to tilt in opposite directions. At this time, the pressure of the swing rod 47 on the compression spring 46 gradually decreases, and the release of the compression spring 46 further provides power for the tilting movement of the swing rod 47 and the transmission rod 43. This causes the swing speed of the transmission rod 43 and the swing rod 47 to increase rapidly, thereby effectively increasing the horizontal reciprocating speed of the clamping plate 35 and the telescopic shaft 36.
[0061] As can be seen from the above, the paddle 31 needs to overcome the resistance of the compression spring 46 during the process of pressing the lever 42 to deflect to the horizontal state. When the lever 42 deflects to the horizontal state, the paddle 31 and the lever 42 are in contact and disengaged. At this time, the lever 42 continues to deflect under the release of the compression spring 46 and is positioned at the maximum angle.
[0062] It should be noted that the adjusting mechanism can control the maximum deflection angle of the swing rod 47. When the maximum deflection angle of the swing rod 47 changes, it pulls the transmission rod 43, causing the deflection angle of the transmission rod 43 to change synchronously. Furthermore, the transmission rod 43 is symmetrical about the support column 4 on both sides of its stroke, meaning that a change in the maximum deflection angle of the transmission rod 43 will cause a synchronous change in its swing stroke. At the same time, the maximum travel distance of the clamping plate 35 is the projected length of the swing stroke of the transmission rod 43 on the horizontal plane, thus causing a synchronous change in the maximum travel distance of the clamping plate 35. The maximum travel distance of the clamping plate 35 is the single travel distance of the steel pipe. The position of the positioning block 53 inside the extension plate 5 is adjusted by rotating the control threaded shaft 52, and the height of the bottom end of the swing rod 47 is further adjusted. When the positioning block 53 rises, the deflection angle of the swing rod 47 increases, and when the positioning block 53 falls, the deflection angle of the swing rod 47 decreases. When the transmission rod 43 swings to the maximum deflection angle of the swing rod 47, the swing rod 47 can no longer deflect and at the same time, it has a limiting effect on the transmission rod 43 to restrict the continued movement of the transmission rod 43. At this time, the clamping plate 35 and the telescopic shaft 36 move to the limit distance of horizontal travel. Thus, by rotating the threaded shaft 52, the function of adjusting the single travel amount of the steel pipe can be realized. Example 5:
[0063] Please see Figure 7-8 This embodiment further illustrates the following based on Embodiment 4: An adjusting wheel 61 is fixedly connected to the bottom end of the adjusting shaft 6. A positioning gear ring 64 is meshed and driven on the outer contour of the adjusting wheel 61. A spiral guide rail 65 is fixedly connected to the outer contour of the positioning gear ring 64 on the side opposite to the adjusting wheel 61. Four mirror-symmetrically arranged transmission blocks 66 are driven on the outer contour of the spiral guide rail 65. The end of each transmission block 66 opposite to the spiral guide rail 65 is limited and slidably connected to the same fixing plate 67, and the fixing plate 67 and the spiral guide rail 65 do not contact each other. A circular groove for the steel pipe to pass through is opened in the middle section of the fixing plate 67, and scale lines are evenly distributed on the edge of the circular groove.
[0064] A chain 62 is connected to the outer contour of the adjusting shaft 6 near the bottom. The other end of the chain 62 is sleeved on a helical gear 63 that passes through and is rotatably connected to the top of the fixed frame 12. The helical gear 63 meshes with the herringbone teeth on the outer contour of the internal thread sleeve 33 and is connected in a transmission manner.
[0065] During the process of the internal threaded sleeve 33 rising and falling due to the rotation of the threaded column 32, the meshing position of the herringbone teeth on the outer contour of the internal threaded sleeve 33 and the helical gear 63 changes synchronously. This process causes the helical gear 63 to rotate synchronously, and during a single rise or fall of the internal threaded sleeve 33, the helical gear 63 reciprocates once. Thus, in the first half of the rise or fall of the drilling rig 15, the helical gear 63 drives the chain 62 and the adjusting shaft 6 to rotate. The adjusting shaft 6 further drives the adjusting wheel 61, the positioning gear ring 64, and the spiral guide rail 65 to rotate synchronously. The rotation of the spiral guide rail 65... This causes the four transmission blocks 66 to tend to rotate synchronously, but the transmission blocks 66 cannot rotate under the limiting action of the fixed plate 67. They can only gradually move towards the center of the circular groove of the fixed plate 67 along the limiting direction of the fixed plate 67. As the transmission blocks 66 gradually move closer, they achieve clamping and fixing of the steel pipe surface and further tightening. In the latter half of the drilling rig 15's ascent or descent, the helical gear 63 rotates in the opposite direction to relax the transmission blocks 66 and the steel pipe. Thus, while completing the intermittent clamping of the steel pipe, it does not affect the movement of the traveling component driving the steel pipe during its travel.
[0066] When it is necessary to rotate the steel pipe to complete multi-angle drilling, the chain 62 is moved upward to disengage from the helical gear 63, at which point the transmission relationship between the adjusting shaft 6 and the helical gear 63 is released. Then, the adjusting shaft 6 is rotated, and the transmission block 66 gradually moves towards the center of the circular groove to clamp and fix the surface of the steel pipe and further tighten it. The fixing plate 67 is further rotated, and the rotation angle of the steel pipe can be determined by observing the scale lines on the surface of the fixing plate 67 to achieve the purpose of precise adjustment.
