[0002] In construction projects, steel pipes are often used as core materials for building various frames and supports. These steel pipes need to be precisely drilled to ensure proper connection and integration with other components.

At the same time, when processing step holes, the above patent can prevent the step holes from deformation.

[0005] However, the above patent lacks the function of positioning the steel pipe. When performing multiple drilling operations, the steel pipe needs to be manually adjusted repeatedly to determine the drilling position. The operation steps are cumbersome and prone to human errors, resulting in reduced drilling accuracy. On the other hand, the above patent is only applicable to vertical drilling operations on rectangular tubes.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0021] See also Figures 1 to 9 The present 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, characterized in that: the horizontal sides of the lower surface of the fixed plate 1 are fixedly connected with support shafts 11, the bottom ends of the two support shafts 11 are fixedly connected with a fixed frame 12, an inverted T-shaped groove is provided inside the fixed frame 12, a lifting block 14 is vertically penetrated and arranged in the fixed plate 1, a plurality of sets of symmetrically arranged vertical guide rails 13 are fixedly connected to the inner contours on the horizontal sides of the fixed plate 1, and the fixed plate 1 and the lifting block 14 are limitedly slidably connected by the vertical guide rails 13, and the center of the lifting block 14 is vertically penetrated and limitedly rotated and connected with a drilling rig 15 driven by a motor; The traveling assembly includes a clamping mechanism for completing the steel pipe transmission work, a swinging mechanism for driving the steel pipe movement, and an adjusting mechanism for controlling the single travel amount of the steel pipe. The clamping mechanism, the swinging mechanism, and the adjusting mechanism are all arranged on the outer contour of the fixed frame 12 at corresponding positions; The deflection mechanism includes an adjustment shaft 6 for realizing intermittent clamping of the steel pipe. The adjustment shaft 6 penetrates through and is rotationally connected to the front and rear sides of the lower surface of the fixed plate 1 in a limited manner.

[0022] In this device, a fixed plate 1, a support shaft 11 and a fixed frame 12 are used as a frame structure to carry the remaining mechanisms while realizing their transmission effects. The lifting block 14 and the drill rig 15 are driven to lift and lower back and forth by the lifting mechanism to complete the drilling operation of the drill rig 15, and the maximum drilling depth of the drill rig 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 lifting movement in the vertical direction, thereby avoiding the deflection of the lifting block 14 and the drill rig 15 and causing the drilling operation to fail.

[0023] On the other hand, the lifting mechanism synchronously controls the operation of the clamping mechanism, and the clamping mechanism 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 clamping of the steel pipe.

[0024] At the same time, the clamping mechanism intermittently controls the swinging mechanism. While the swinging mechanism realizes reciprocating swing, it drives the clamping mechanism to synchronously reciprocate horizontally under the limiting action of the fixed frame 12. Specifically, when the clamping mechanism clamps the steel pipe, the swinging mechanism drives the clamping mechanism to complete unilateral horizontal movement. When the clamping mechanism is relaxed, the swinging mechanism drives the clamping mechanism to return to the initial position, thereby completing the intermittent pushing and moving operation of the steel pipe.

[0025] 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, thereby improving the degree of automation of the device.

[0026] Furthermore, the clamping mechanism synchronously transmits the deflection mechanism, which also completes the intermittent clamping operation of the steel pipe but has the opposite effect to that of the clamping mechanism. Specifically, when the clamping mechanism clamps the steel pipe, the deflection mechanism relaxes its clamping of the steel pipe, and when the clamping mechanism relaxes, the deflection mechanism clamps the steel pipe, thereby achieving full clamping and fixation of the steel pipe while maintaining the movement between the clamping mechanism and the deflection mechanism without interfering with each other. Therefore, when drilling the steel pipe, the clamping of the steel pipe by the deflection mechanism can effectively prevent the vibration of the steel pipe and cause drilling failure, and after the 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.

[0027] It should be noted that the rotation angle of the steel pipe can be adjusted by controlling the adjustment shaft 6 through the deflection mechanism transmission, thereby meeting the functional requirements of multi-angle drilling of the steel pipe. Example

[0028] See also Figure 4 This embodiment is further described on the basis of the first embodiment: the lifting mechanism includes a fixed seat 2 fixedly connected to the front and rear sides of the upper surface of the fixed plate 1, the fixed seat 2 is penetrated from front to back and is rotatably connected with a driving shaft 21, the end of the driving shaft 21 away from the fixed plate 1 is fixedly connected with a transmission wheel 22, the end of the driving shaft 21 pointing to the fixed plate 1 is fixedly connected with a telescopic connecting rod group 23, the other end of the telescopic connecting rod group 23 is penetrated and limitedly rotatably connected to the front and rear sides of the lifting block 14, the bottom end of the transmission wheel 22 is meshed and transmission-connected with a transmission gear ring 24 on the outer contour of the fixed plate 1 with limited rotation.

[0029] A motor is arranged in the fixed seat 2 and the motor controls the driving shaft 21 to realize rotation. When the motor is turned on, the driving shaft 21 drives the transmission wheel 22 and the transmission gear ring 24 to rotate synchronously. At the same time, the telescopic connecting rod group 23 rotates and realizes the lifting operation of the lifting block 14 and the drilling rig 15 under the limiting action of the vertical guide rail 13. Specifically, when the telescopic connecting rod group 23 rotates, its state changes of folding and stretching occur synchronously, and the lifting block 14 and the drilling rig 15 are lifted and lowered synchronously to realize the drilling operation of the steel pipe.

[0030] It should be noted that when the drive shaft 21 rotates one circle, the telescopic connecting rod group 23 rotates 360° synchronously. During this process, the telescopic connecting rod group 23 passes through two horizontal positions and vertical positions. When the telescopic connecting rod group 23 is in the horizontal position, it reaches the maximum folding degree, and the lifting block 14 and the drilling rig 15 are at the same horizontal height position as the transmission gear ring 24. At this time, the lifting block 14 and the drilling rig 15 reach the middle section of their lifting stroke; when the telescopic connecting rod group 23 is at the lowest point or the highest point in the vertical position, it reaches the maximum extension degree. At this time, the lifting block 14 and the drilling rig 15 are synchronously at the highest point or the lowest point of the lifting stroke; that is, in the process of the telescopic connecting rod group 23 rotating one circle with the drive shaft 21, two folding and extension state changes occur, and the lifting block 14 and the drilling rig 15 synchronously complete a reciprocating lifting operation, and this process corresponds to the drilling rig 15 completing a drilling and resetting operation of the steel pipe.

[0031] by Figure 4 For example, the telescopic link group 23 is initially in a horizontal position on the right side of the drive shaft 21. At this time, the lifting block 14 and the drilling rig 15 are in the middle of the stroke. As the drive shaft 21 rotates clockwise, the telescopic link group 23 rotates synchronously and unfolds downward. When the drive shaft 21 rotates 90°, the telescopic link group 23 reaches the maximum extension degree. At this time, the lifting block 14 and the drilling rig 15 are at the lowest point of the lifting stroke; then the drive shaft 21 continues to rotate, and the telescopic link group 23 begins to fold upward. When the drive shaft 21 rotates 90° again, the telescopic link group 23 The group 23 is in a horizontal folded state again and is located on the left side of the driving shaft 21. At this time, the lifting block 14 and the drilling rig 15 rise synchronously and return to the middle of their stroke; further, the driving shaft 21 rotates 90° again. During this process, the telescopic connecting rod group 23 unfolds upward and drives the lifting block 14 and the drilling rig 15 to move to the highest point of their lifting stroke; then the driving shaft 21 rotates further 90°, the telescopic connecting rod group 23 folds downward and returns to a horizontal state located on the right side of the driving shaft 21, and the lifting block 14 and the drilling rig 15 are synchronously reset to the middle of their stroke.

[0032] It should be noted that by adjusting the telescopic length of the telescopic link group 23 itself, its maximum extension can be controlled. The maximum extension of the telescopic link group 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 drilling rig 15 and the lowest point is equal to the maximum extension of the telescopic link group 23, and the middle section of the stroke of the lifting block 14 and the drilling rig 15, that is, the distance between the horizontal height position of the transmission ring gear 24 and the highest point or the lowest point of the stroke of the lifting block 14 and the drilling rig 15 is equal to half the length of the maximum extension of the telescopic link group 23, thereby completing the adjustment of the maximum drilling depth of the drilling rig 15. Example

[0033] See also Figure 5, this embodiment is further described on the basis of the second embodiment: the clamping mechanism includes a crown gear 3 meshed and transmission-connected to the horizontal sides of the transmission gear ring 24, the top of the crown gear 3 is fixedly connected with a paddle 31, the axis of the crown gear 3 is fixedly connected with a threaded column 32 extending downward, the bottom end of the threaded column 32 is screwed with an internal threaded sleeve 33 through a reciprocating thread, the internal threaded sleeve 33 penetrates and is limitedly slidably connected to the top of the fixed frame 12, the outer contour of the top of the internal threaded sleeve 33 is provided with a herringbone tooth, the bottom end of the internal threaded sleeve 33 is fixedly connected with a squeeze block 34 that is limitedly lifted and slidably connected to the inside of the inverted T-slot of the fixed frame 12, the end of the squeeze block 34 away from the fixed frame 12 is arranged with a downward inclined surface, and a clamping plate 35 is transmission-connected on the inclined surface of the squeeze block 34, the end of the clamping plate 35 pointing to the fixed frame 12 is fixedly connected with a telescopic shaft 36 that is limitedly horizontally slidably connected to the inside of the inverted T-slot of the fixed frame 12, and a return spring is arranged inside the telescopic shaft 36.

[0034] Furthermore, when the transmission ring gear 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 internal threaded sleeve 33 to rotate, but the internal threaded sleeve 33 cannot rotate due to the limited sliding connection between it and the fixed frame 12, resulting in the internal threaded sleeve 33 realizing its own reciprocating lifting and lowering motion at the top of the fixed frame 12 under the rotation of the threaded column 32.

[0035] 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 circle, the crown gear 3 also rotates one circle and the internal threaded sleeve 33 realizes one reciprocating lifting, so that the lifting process of the internal threaded sleeve 33 corresponds to the lifting process of the drilling rig 15.

[0036] When the internal threaded sleeve 33 descends, it pushes the extrusion block 34 to synchronously descend along the vertical direction of the inverted T-slot of the fixed frame 12. At this time, the extrusion block 34 further squeezes the clamping plate 35, and the clamping plate 35 is restricted in the horizontal direction of the inverted T-slot of the fixed frame 12 and cannot descend, thereby causing the clamping plate 35 to be extruded toward the steel pipe and complete the clamping operation of the steel pipe. In this process, the clamping plate 35 pulls the telescopic shaft 36 to move synchronously, and the other end of the telescopic shaft 36 is limited by the swing mechanism, causing the telescopic shaft 36 to be stretched, and the return spring inside it is stretched synchronously.

[0037] When the internal threaded sleeve 33 rises, the extrusion block 34 rises synchronously and releases the extrusion 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 clamping the steel pipe. Therefore, during the process of the fixed seat 2 rotating one circle, the clamping plate 35 realizes the process of clamping and loosening the steel pipe.

[0038] It should be noted that, by setting the initial threaded connection direction between the reciprocating thread of the internal threaded sleeve 33 and the threaded column 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 is first relaxed and then clamped 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 descends and realizes the process of drilling a hole in the steel pipe, the clamping plate 35 does not contact the steel pipe, and then in the process of rising and resetting the drilling rig 15, the clamping plate 35 squeezes out and clamps the steel pipe. Example

[0039] See also Figure 6 , this embodiment is further described on the basis of the third embodiment: the swing mechanism includes a support column 4 fixedly connected to the upper surface of the fixed frame 12 away from the fixed plate 1, the top of the support column 4 is horizontally penetrated and limitedly rotated with 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 transmission-connected with the paddle 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 limiting the lifting and sliding connection of the telescopic shaft 36.

[0040] The bottom end of the transmission rod 43 is fixedly connected to a limit frame 44 on one side away from the fixed frame 12, and a slider 45 is connected to the limit frame 44 for limiting sliding inside. A compression spring 46 arranged inside the limit frame 44 is fixedly connected between the slider 45 and the inner contour of the top end of the limit frame 44, and a swing rod 47 is penetrated and connected to the end of the slider 45 away from the fixed frame 12 for limiting rotation.

[0041] The adjustment mechanism includes an extension plate 5 fixedly connected to the outer surface of the bottom end of the fixed frame 12 away from the clamping plate 35. The extension plate 5 extends upward and is fixedly connected to a fixed block 51. The internal limiting sliding connection of the fixed block 51 is connected to a positioning block 53. The extension plate 5 is vertically penetrated and extended downward by a threaded shaft 52. The threaded shaft 52 is screwed to the positioning block 53. The positioning block 53 penetrates one end away from the fixed frame 12 and is connected to the bottom end of the swing rod 47 for limiting rotation.

[0042] During the rotation of the crown gear 3, the paddle 31 rotates synchronously and continuously moves the paddle 42 to deflect it to both sides. Figure 6Taking the initial position of the paddle 31 shown in as an example, at this time, the paddle 31 does not contact the lever 42. When the paddle 31 rotates to the left side of the lever 42 along with the crown gear 3, 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 are separated again and continue to rotate along with the crown gear 3. When the paddle 31 contacts the right side of the lever 42, the paddle 31 contacts and squeezes the lever 42 again, 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, in the process of one rotation of the crown gear 3, the paddle 31 just drives the lever 42 to reciprocate 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.

[0043] Furthermore, the transmission rod 43 synchronously drives the limit plate 48 to swing back and forth. At this time, the limit plate 48 has a tendency to drive the telescopic shaft 36 to swing synchronously, but the telescopic shaft 36 is restricted in the horizontal direction of the inverted T-slot of the fixed frame 12, so that the telescopic shaft 36 can only perform horizontal reciprocating motion. At the same time, the contact position of the vertical groove of the limit plate 48 and the telescopic shaft 36 changes synchronously. The setting of the vertical groove on the limit plate 48 eliminates the stress generated by the conversion of the swing of the limit plate 48 into the horizontal motion of the telescopic shaft 36, 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 motion of the clamping plate 35 drives the steel pipe to move forward. If the clamping plate 35 is not in contact with the steel pipe, the horizontal motion of the clamping plate 35 realizes its own resetting.

[0044] It should be noted that one rotation of the crown gear 3 corresponds to one reciprocating swing of the limit plate 48, that is, the clamping plate 35 reciprocates horizontally once, and at the same time, the clamping plate 35 realizes the clamping or loosening of the steel pipe, that is, the overall movement change of the clamping plate 35 is that in the first half of the rotation of the crown gear 3, the clamping plate 35 gradually relaxes the clamping of the steel pipe until there is no contact with the steel pipe, and then the paddle 31 paddles the paddle rod 42 once, and at this time the clamping plate 35 quickly moves horizontally to the limit distance. The above process corresponds to the downward pressure drilling operation of the drilling rig 15; then, in the crown gear In the second half of the rotation of the wheel 3, the clamping plate 35 is gradually squeezed out and the steel pipe is clamped. At this time, the paddle 31 pushes the lever 42 again, and the clamping plate 35 moves horizontally and resets. In this process, the clamping plate 35 drives the steel pipe to move synchronously to complete the intermittent pushing and moving operation of the steel pipe. This process corresponds to the rising and resetting process of the drilling rig 15 and the moving operation is started only when the drilling rig 15 rises to near the highest point, thereby effectively avoiding the movement interference caused by the drilling rig 15 not being able to detach from the steel pipe in time during the moving process, thereby effectively ensuring the stability of the steel pipe moving operation.

[0045] Furthermore, during the swinging of the transmission rod 43, the limit frame 44 drives the slider 45 and the upper end of the swing rod 47 to swing synchronously, while the lower end of the swing rod 47 is restricted by the adjustment mechanism and cannot move horizontally, resulting in the swing rod 47 synchronously deflecting back and forth to both sides during the swinging of the transmission rod 43. During this process, since the length of the swing rod 47 is fixed and its bottom end position is fixed, the swing rod 47 will synchronously drive the slider 45 to change its position inside the limit frame 44, and the compression spring 46 will be synchronously compressed or released. During the swinging of the transmission rod 43, in the first half of the swinging, it approaches the vertical state of the middle section from the inclined state, and at this time, the swing rod 47 synchronously approaches the vertical state of the middle section from the inclined state, and the compression spring 46 is synchronously compressed. After the transmission rod 43 passes the middle vertical position, the transmission rod 43 and the swing rod 47 have a tendency to tilt in the opposite direction. 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 to the tilting movement of the swing rod 47 and the transmission rod 43. The swing speed of the transmission rod 43 and the swing rod 47 is rapidly accelerated, thereby effectively improving the speed of the horizontal reciprocating movement of the clamping plate 35 and the telescopic shaft 36.

[0046] From the above, it can be seen that the paddle 31 needs to overcome the resistance of the compression spring 46 in the process of squeezing the lever 42 to deflect to the horizontal state. When the lever 42 is deflected to the horizontal state, the paddle 31 is out of contact with the lever 42. At this time, the lever 42 continues to deflect and is positioned at the maximum angle under the release of the compression spring 46.

[0047] It should be noted that the adjustment mechanism can control the maximum deflection angle of the swing rod 47, and when the maximum deflection angle of the swing rod 47 changes, it pulls the transmission rod 43 so that the deflection angle of the transmission rod 43 changes synchronously; further, the transmission rod 43 is symmetrical on both sides of the support column 4 as the axis in the movement stroke, that is, the change of the maximum deflection angle of the transmission rod 43 will cause its swing stroke to change synchronously, and at the same time, the maximum travel distance of the clamping plate 35 is the projection length of the swing stroke of the transmission rod 43 on the horizontal plane, so that the maximum travel distance of the clamping plate 35 changes synchronously, and the maximum travel distance of the clamping plate 35 is the single travel distance of the steel pipe; By controlling the threaded shaft 52 to rotate and adjust the position of the positioning block 53 inside the extension plate 5, 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 drops, the deflection angle of the swing rod 47 decreases; when the transmission rod 43 swings to the point where the swing rod 47 is at the maximum deflection angle, the swing rod 47 cannot continue to deflect and at the same time exerts a limiting effect on the transmission rod 43 to limit 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, so that the function of the device to adjust the single travel amount of the steel pipe can be realized by rotating the threaded shaft 52. Example

[0048] See also Figure 7-8 This embodiment is further described on the basis of the fourth embodiment: an adjusting wheel 61 is fixedly connected to the bottom end of the adjusting shaft 6, a positioning gear ring 64 is meshed and transmission-connected 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 away from the adjusting wheel 61, four mirror-symmetrically arranged transmission blocks 66 are transmission-connected to the outer contour of the spiral guide rail 65, and the ends of the transmission blocks 66 away from the spiral guide rail 65 are both limitedly slidably connected to the same fixed plate 67, and there is no contact between the fixed plate 67 and the spiral guide rail 65, and a circular groove for the steel pipe to pass through is opened in the middle section of the fixed plate 67, and scale lines are evenly distributed on the edge of the circular groove.

[0049] A chain 62 is transmission-connected on the outer contour of the adjusting shaft 6 near the bottom end, and the other end of the chain 62 is sleeved on a bevel gear 63 that penetrates and is rotationally limitedly connected to the top of the fixed frame 12. The bevel gear 63 meshes with the herringbone teeth on the outer contour of the internal threaded sleeve 33 and is transmission-connected.

[0050] In the process of the threaded column 32 rotating to cause the internal threaded sleeve 33 to rise and fall, the meshing position of the herringbone teeth on the outer contour of the internal threaded sleeve 33 and the bevel gear 63 changes synchronously, and this process causes the bevel gear 63 to rotate synchronously. In the single rise or fall process of the internal threaded sleeve 33, the bevel gear 63 reciprocates once, so that in the first half of the rise or fall of the drilling rig 15, the bevel gear 63 drives the chain 62 and the adjusting shaft 6 to rotate, and the adjusting shaft 6 further drives the adjusting wheel 61, the positioning gear ring 64 and the spiral guide rail 65 to rotate synchronously, and the rotation of the spiral guide rail 65 As a result, the four transmission blocks 66 tend to rotate synchronously, but the transmission blocks 66 cannot rotate due to the limiting effect of the fixed plate 67, and can only gradually move toward the center position 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 clamp and further tighten the surface of the steel pipe; in the second half of the ascent or descent of the drilling rig 15, the bevel gear 63 rotates in the opposite direction to loosen the steel pipe of the transmission block 66, thereby completing the intermittent clamping of the steel pipe without affecting the movement of the steel pipe driven by the traveling assembly during the traveling process.

[0051] When it is necessary to rotate the steel pipe to complete the multi-angle drilling operation, the chain 62 is moved up to make it disengage from the bevel gear 63. At this time, the transmission relationship between the adjusting shaft 6 and the bevel gear 63 is released; then the adjusting shaft 6 is rotated, and the transmission block 66 begins to gradually move toward the middle of the circular groove and completes the clamping and further clamping of the steel pipe surface, and further rotates the fixing plate 67. By observing the scale lines on the surface of the fixing plate 67, the rotation angle of the steel pipe can be judged to achieve the purpose of precise adjustment.
