Description

Technical Field

[0001] The invention relates to the technical field of sonic detection tube cutting, and in particular to a sonic detection tube positioning cutting device and a positioning method. Background Art

[0002] The sonic detection tube is a sonic detection tube, which is mainly used in conjunction with ultrasonic detection equipment to detect the internal state of the cast-in-place pile.

[0003] According to the publication (announcement) number CN220463418U, the publication (announcement) date is 2024-02-09, and a kind of ultrasonic detection pipe grinding wheel cutting machine is disclosed, including a cutting table, a slide groove and a pipe cutting table, a slide groove is provided in the middle of the cutting table, and a cylinder is fixedly installed at the front end of the slide groove, and a pipe cutting table is fixedly installed at the end of the cylinder, a hinge seat is fixedly installed on the right side of the cutting table, and the cutting machine is fixedly connected between the hinge seats. This device places the ultrasonic detection pipe by setting a pipe cutting table, and a cutting groove is provided on the pipe cutting table, so that the cutting machine can prevent the cutting knife from cutting the pipe cutting table by mistake when cutting, and then the motor is started to drive the cutting machine to rotate at high speed to cut the ultrasonic detection pipe. After cutting a section, when the remaining ultrasonic detection pipe needs to be cut, the cylinder is used to work horizontally, and the pipe cutting table installed at the end of the cylinder rod is driven to move, so that the position where it needs to be cut is moved to the cutting machine, and then cut again. This method avoids the need for the staff to reposition and adjust the ultrasonic detection pipe after taking out the cut ultrasonic detection pipe each time when cutting the ultrasonic detection pipe multiple times, which effectively improves the work efficiency.

[0004] In the prior art including the above patents, the sonic detection pipe needs to be connected with a pipe joint during use, and the most commonly used one is the clamp-type sonic detection pipe joint. When producing the clamp-type sonic detection pipe joint, a predetermined length is generally cut from the pipe blank by a cutting machine, and then the cut section of the pipe is reprocessed. The cutting machine often applies a large pressure to the sonic detection pipe when cutting it, and the high-speed rotating cutting blade and the sonic detection pipe will generate heat by friction. The sonic detection pipe at high temperature is easily deformed under a certain pressure, resulting in the cross section of the cut pipe head not being a perfect circle, which in turn affects subsequent use.

[0053] Specifically, after the cutting work is completed, the heating cylinder 146 heats the pipe 2, and then the push rod 125 on the movable disk 121 and the push rod 125 on the mounting ring 123 move in a direction away from the axis of the pipe 2, and the push rod 125 pushes the pipe 2 to make the pipe 2 bulge. At the same time, the second movable tube 12 drives the push rod 125 to rotate, and multiple push rods 125 push the pipe 2, so that the pipe 2 forms two annular bulges for subsequent use.

[0054] As another embodiment further provided by the present invention, the movable disk 121 moves so that the push rod 125 thereon pulls the pipe 2 to move, and the fixing ring 144 extends to the outside of the pipe 2 .

[0055] Specifically, a chuck 143 located between the mounting ring 123 and the movable disk 121 and used to fix the pipeline 2 is rotatably provided on the frame 1 , and the movable disk 121 is slidably mounted on the second movable pipe 12 .

[0056] Furthermore, during the rotation of the second movable tube 12, the push rod 125 on the movable disk 121 and the push rod 125 on the mounting ring 123 push the pipe 2, so that two protrusions are formed on the pipe 2. At the same time, the movable disk 121 moves to approach the mounting ring 123 to pull the cut pipe 2 toward the heating cylinder 146 to prevent the part between the two protrusions from being broken due to excessive pulling. At the same time, the cutting surface contacts the fixing ring 144, and the fixing ring 144 pushes the burrs on the inner wall of the pipe 2 for subsequent processing.

[0057] As another embodiment further provided by the present invention, a third movable tube 13 is disposed on the frame 1 , and movable rings 131 for driving the plurality of push rods 125 to move are symmetrically disposed on the third movable tube 13 .

[0059] Furthermore, when the third movable tube 13 rotates relative to the second movable tube 12 , the third movable tube 13 drives the movable ring 131 to rotate, and the planar thread on the movable ring 131 moves along the sliding groove on the push rod 125 to push the push rod 125 to move relative to the second movable tube 12 .

[0060] As another embodiment further provided by the present invention, one movable ring 131 is rotatably mounted on the movable disk 121 , and the third movable tube 13 rotates and moves along the axis of the pipeline 2 to pull the movable disk 121 to slide along the second movable tube 12 .

[0061] Specifically, the movable ring 131 matched with the push rod 125 on the mounting ring 123 is slidably installed on the third movable tube 13, and a spring is arranged between the movable ring 131 and the third movable tube 13, a threaded hole is arranged on the frame 1, and a threaded portion adapted to the threaded hole is arranged on the third movable tube 13.

[0062] Furthermore, during the rotation of the third movable tube 13 , the threaded portion of the third movable tube 13 moves along the thread line of the threaded hole on the frame 1 , thereby driving the movable ring 131 to move along the second movable tube 12 via one of the movable rings 131 .

[0063] Furthermore, in the above embodiment, a clamping block for limiting the corresponding movable ring 131 may be provided on the movable disk 121 , so that the movable disk 121 moves along with the corresponding movable ring 131 .

[0064] As another embodiment further provided by the present invention, a support rod 122 is provided between the movable disk 121 and the mounting ring 123 , and the support rod 122 is retracted to allow the retractable mounting ring 123 to remain in place during the movement of the movable ring 131 .

[0065] Specifically, a support rod 122 passing through the movable disk 121 and the second movable tube 12 is provided between the movable disk 121 and the second movable tube 12 , and the support rod 122 is specifically a self-elastic telescopic rod.

[0066] Furthermore, a second gear ring 132 is provided on the third movable tube 13, a support ring 127 is provided on the second movable tube 12, a rotation damper is provided between the support ring 127 and the frame 1, a first gear 113 meshing with the first gear ring 112 is rotatably provided on the frame 1, a shaft 115 is provided on the first gear 113, a second gear 114 meshing with the second gear ring 132 is slidably provided on the shaft 115, a convex ring 116 is provided on the second gear 114 to keep it always in meshing state with the second gear ring 132, a support seat 145 for supporting the steel pipe is provided on the frame 1, and the transmission ratio between the second gear ring 132 and the second gear 114 is greater than the transmission ratio between the first gear ring 112 and the first gear 113.

[0067] Furthermore, when cutting, the pipe 2 is placed on the frame 1 and put on the mounting rod 14. The end of the pipe 2 is against the frame 1. The motor outputs torque to drive the mounting rod 14 to rotate. The mounting rod 14 rotates with the mounting plate 147. The first gear ring 112 is blocked by the rotation damper, so that the first movable tube 11 rotates relative to the mounting rod 14. The flat thread on the mounting plate 147 moves along the slide groove on the second slider 142, and pushes the second slider 142 to approach the inner wall of the pipe 2, and the protrusion of the second slider 142 pushes the first slider 141, so that the first slider 141 approaches the inner wall of the mounting plate, and the second slider 142 and the first slider 141 form a fixing ring 144 to fix the pipe 2.

[0068] The mounting rod 14 continues to rotate, at which time the first slider 141 and the second slider 142 can no longer move and provide a reaction force to the drive ring, thereby driving the first movable tube 11 to rotate, and the pipe 2 rotates with the mounting rod 14. The gear ring on the first movable tube 11 drives the third gear 156 to rotate, thereby driving the take-up drum 155 to rotate, and the take-up drum 155 reels in the traction rope 154 to drive the sliding seat 151 to move downward along the guide rail 15, and the sprocket 153 rotates to drive the cutting chain 152 to move and cut the pipe 2, and in the process of the movable seat moving downward, the depth of the cutting chain 152 cutting the pipe 2 gradually deepens, and the cutting chain 152 is adjacent to the mounting plate 147 on the vertical plane. The mounting plate 147 can provide support for the inner side of the cut pipe 2 to avoid excessive deformation of the cut pipe 2.

[0069] At the same time, the first toothed ring 112 on the first movable tube 11 drives the first gear 113 to rotate, the first gear 113 drives the second gear 114 to rotate through the shaft 115, the second gear 114 drives the third movable tube 13 to rotate through the second toothed ring 132 meshing therewith, the third movable tube 13 drives the movable ring 131 to rotate, and at this time the second movable tube 12 is blocked by the rotation damper, the movable ring 131 rotates relative to the second movable tube 12, and the flat thread on the movable ring 131 drives the push rod 125 to move and gradually approach the inner wall of the pipe 2.

[0070] When the cutting chain 152 cuts the pipe 2, the movable ring 131 also pushes the push rod 125 against the inner wall of the pipe 2. At this time, the heating cylinder 146 heats the pipe 2, and the push rod 125 pushes the pipe 2 to deform the pipe 2. Since the transmission ratio between the second gear ring 132 and the second gear 114 is greater than the transmission ratio between the first gear ring 112 and the first gear 113, the speed at which the first movable pipe 11 and the mounting rod 14 rotate with the pipe 2 is greater than the speed at which the third movable pipe 13 drives the push rod 125 to rotate, so that the push rod 125 pushes out an annular protrusion on the pipe 2, and during the rotation of the third movable pipe 13, the threaded portion on the third movable pipe 13 moves along the The thread line of the threaded hole on the frame 1 moves, thereby driving the movable ring 131 to move along the second movable tube 12 through one of the movable rings 131, the support rod 122 between the movable disk 121 and the mounting ring 123 is compressed, the pull rope 124 pulls the mounting ring 123 to stay in place, and the movable disk 121 approaches the mounting ring 123 to pull the end of the cut pipe 2 close to the heating tube 146 to prevent the part between the two protrusions from being broken due to excessive pulling. At the same time, the cutting surface contacts the fixed ring 144, and the fixed ring 144 pushes the burrs on the inner wall of the pipe 2 for subsequent processing, and the chuck 143 limits the flat part between the two protrusions.

[0071] After the processing is completed, the motor outputs a reverse torque to drive the mounting rod 14 to rotate in the opposite direction, thereby causing the first movable tube 11 to rotate in the opposite direction relative to the mounting rod 14, thereby driving the second slider 142 to approach the axis of the pipeline 2, and the third movable tube 13 to rotate in the opposite direction relative to the second movable tube 12, thereby driving the push rod 125 to approach the axis of the pipeline 2. At this time, the processed pipe joint can be removed for subsequent use.
