Description

Technical Field

[0001] The invention relates to the technical field of pipe pile construction, in particular to a ring cutting frame for pipe pile production and a ring cutting method thereof. Background Art

[0002] In the process of pipe pile production, cutting pipe piles is an important and challenging task. The traditional pipe pile cutting method has many disadvantages, which seriously affect the production efficiency, cutting quality and operation safety.

[0003] On the one hand, if the pipe pile is cut directly with a rope saw, since the concrete material of the pipe pile has a certain hardness and toughness, the rope saw needs to spend a lot of time and energy to break the integrity of the pipe pile surface, making the cutting process extremely slow and greatly reducing production efficiency. Moreover, the rope saw is very easy to slide on the surface of the pipe pile, making it difficult to accurately locate the cutting position, which makes the cut surface extremely uneven, seriously affecting the subsequent use of the pipe pile.

[0004] On the other hand, when the saw blade is cutting pipe piles, especially when cutting pipe piles with high hardness or containing coarse aggregates, the friction and impact between the saw teeth of the saw blade and the pipe pile material may cause the cut surface to be rough. This is because during the cutting process, the saw teeth may cause tiny cracks and tears on the surface of the pipe pile, thus affecting the flatness of the cut surface. Its cutting accuracy may be limited by factors such as the thickness of the saw blade, the installation accuracy of the saw blade, and the vibration during the cutting process. The saw blade itself has a certain thickness, which means that a certain width of the cutting seam will be generated during the cutting process, making it difficult to achieve a very high standard of dimensional accuracy of the cut pipe pile.

[0005] Therefore, there is an urgent need for a new ring cutting frame and ring cutting method for pipe pile production to solve the problems of low efficiency and poor precision existing in the above-mentioned traditional cutting method. Summary of the invention

[0009] A rope saw mechanism is provided on the top of the lower base plate, and the rope saw mechanism is used to cut again along the cutting opening on the pipe pile to cut the pipe pile evenly. At the same time, the pipe pile is clamped by two clamping structures during the cutting process to prevent the waste pipe pile from falling directly after cutting.

[0010] Preferably, a plurality of groups of lifting rings are installed on the top of the upper base plate, and lifting is performed through the plurality of lifting rings.

[0011] Preferably, the clamping structure includes a rotatable movable ring arranged inside the cutting circular mouth, and the upper and lower surfaces of the movable ring are provided with a plurality of groups of positioning columns distributed in a circular array, and the upper and lower surfaces of the upper base plate and the lower base plate are hinged with a plurality of groups of load-bearing frames distributed in a circular array, and the load-bearing frames are provided with movable openings for movement with the positioning columns, and positioning claws are installed at one end of the upper and lower corresponding load-bearing frames, and a connecting beam is installed on the movable ring, and the connecting beam is driven by an A electric cylinder so that the connecting beam drives the movable ring to rotate, and the positioning column moves at the movable opening on the load-bearing frame, so that the load-bearing frame rotates to output and clamp the pipe pile.

[0012] Preferably, two ends of the A electric cylinder on the upper base plate are respectively connected to the connecting beam and the upper base plate by a hinged manner, and two ends of the A electric cylinder on the lower base plate are respectively connected to the connecting beam and the lower base plate by a hinged manner.

[0013] Preferably, the ring cutting structure includes a turntable bearing arranged on the top of the lower base plate and distributed around the cutting circle. The lower base plate is rotatably connected to the fixed ring through the turntable bearing. A movable beam is hinged on the inner side of the fixed ring, and a cutting saw blade driven by a motor is provided at the other end of the movable beam. A B electric cylinder is hinged on the inner side of the fixed ring, and the other end of the B electric cylinder is hinged to the side of the movable beam. The movable beam is pushed to rotate by the extension and retraction of the B electric cylinder, so that the cutting saw blade contacts the pipe pile, and the fixed ring is driven to rotate by the motor.

[0014] Preferably, a tooth groove is provided on the outer side of the fixing ring, a rotatable gear is provided on the lower base plate, and the gear is meshed with the tooth groove on the fixing ring, and the gear is driven by a motor so that the fixing ring drives the cutting saw blade to cut a cutting opening along the side of the pipe pile.

[0015] Preferably, the rope saw mechanism includes two guide rails and a linear motor installed on a lower base plate, and a U-shaped frame is installed on the sliders of the two guide rails, the slide of the linear motor is connected to the bottom of the U-shaped frame, and a plurality of guide wheels distributed in a rectangular shape and a driving wheel are installed on the U-shaped frame, and a transmittable rope saw is provided on the guide wheel and the driving wheel, which is driven by a motor through the driving wheel.

[0016] Preferably, the cutting positions of the rope saw mechanism and the ring cutting structure are in the same horizontal plane, a circle of notches is cut on the side of the pipe pile by the ring cutting structure, and then the rope saw mechanism performs depth cutting along the notches.

[0017] A ring cutting method for pipe pile production, the specific operation is as follows:

[0018] S1, inserting the pipe pile into the cut circular openings on the upper base plate and the lower base plate, and clamping the side of the pipe pile by the clamping structures on the upper base plate and the lower base plate, and tying the pipe pile with the cut sleeve by a rope;

[0019] S2. Then the ring cutting structure cuts a circle of cutting openings on the side of the pipe pile, and the ring cutting structure finally moves to the position opposite to the rope saw mechanism, and then the rope saw mechanism moves forward and continues cutting along the cutting opening until the pipe pile is cut off, and finally the clamping structure on the upper base plate is released, and finally the cut pipe pile is hoisted out by the rope.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] (1) The circular cutting structure is used to first open a circle of flat cutting openings on the pipe pile, and then the rope saw mechanism performs deep cutting along the cutting opening, taking advantage of the fast opening of the saw blade cutting machine and the suitability of the rope saw for deep cutting. The pre-opening of the saw blade reduces the resistance of the rope saw when cutting into the pipe pile, speeds up the cutting speed of the rope saw, greatly shortens the overall cutting time, improves production efficiency, and ensures the flatness of the cut surface after cutting.

[0022] (2) The clamping structure at the cutting circle of the upper and lower substrates can firmly fix the pipe pile during the cutting process to prevent the pipe pile from shaking, greatly improving the cutting stability and ensuring that the cutting process is not affected by the displacement of the pipe pile, thereby ensuring the cutting accuracy and making the cross-section of the pipe pile smooth after cutting, meeting production requirements. During the entire cutting process, the two clamping structures always clamp the pipe pile, effectively preventing the waste pipe pile from falling directly after cutting, avoiding possible damage to the operator and surrounding equipment, and ensuring the safety of the operation site.

[0023] (3) Several sets of lifting rings are installed on the top of the upper base plate. In actual use, the entire ring cutting frame can be easily lifted by lifting equipment, so that the equipment can perform pipe pile cutting operations at different positions. This greatly improves the mobility and applicability of the equipment and can better adapt to different working scenarios and pipe pile distribution conditions.

[0024] (4) The circular cutting structure can accurately adjust the contact pressure and cutting depth between the cutting saw blade and the pipe pile by controlling the extension and contraction of the B electric cylinder, thereby ensuring the flatness and quality of the cutting edge and providing a good foundation for the subsequent cutting of the rope saw mechanism.

[0031] In order to make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. In order to keep the following description of the embodiments of the present disclosure clear and concise, the present disclosure omits detailed descriptions of known functions and known components to avoid unnecessary confusion of the concepts of the present invention.

[0032] See also Figure 1 and Figure 2 A ring cutting frame for pipe pile production The ring cutting frame for pipe pile production is mainly composed of an upper base plate 1, a lower base plate 2 and a plurality of connecting columns 3 connecting the two. A cutting circular opening for inserting pipe piles is provided on both the upper base plate 1 and the lower base plate 2, and a clamping structure 4 is provided at the cutting circular opening. In practical application, after the pipe pile is inserted into the cutting circular opening, the pipe pile is clamped by two clamping structures 4 to ensure that the equipment remains stable during the cutting process and to prevent the pipe pile from shaking and affecting the cutting effect.

[0033] A ring cutting structure 5 and a rope saw mechanism 6 are provided on the top of the lower base plate 2. The ring cutting structure 5 is used to open a circle of smooth cutting openings on the pipe pile, and the rope saw mechanism 6 cuts again along the cutting openings opened by the ring cutting structure 5 on the pipe pile, so as to cut the pipe pile smoothly. At the same time, during the entire cutting process, the pipe pile is clamped by two clamping structures 4 to prevent the waste of the pipe pile from falling directly after cutting, thereby ensuring safe operation.

[0034] The concrete material of the pipe pile has a certain hardness and toughness. If the wire saw is used directly for cutting, it will take more time and energy to break the integrity of the pipe pile surface at the beginning, and the cutting process will be slow. After the saw blade cutter opens, the wire saw can directly enter the broken incision, reducing the resistance to cutting and thus speeding up the cutting speed. If the wire saw is used directly for cutting, the wire saw can easily slide on the surface of the pipe pile, making it difficult to accurately locate the cutting position. This results in an uneven cut surface after cutting.

[0035] Several groups of lifting rings 7 are installed on the top of the upper base plate 1. In actual use scenarios, the entire ring cutting frame can be easily lifted by lifting equipment through these lifting rings 7, which is convenient for performing pipe pile cutting operations at different positions, thereby improving the mobility and applicability of the equipment.

[0036] See also Figure 3 The clamping structure 4 is mainly composed of a movable ring 41, a positioning column 42, a load-bearing frame 43, a positioning claw 45, a connecting beam 46 and an A electric cylinder 47. The movable ring 41 is arranged inside the cutting circular opening and can rotate around the central axis of the cutting circular opening. A plurality of groups of positioning columns 42 in a circular array are evenly distributed on the upper and lower surfaces of the movable ring 41, and the positioning columns 42 and the movable ring 41 are fixed by welding or threaded connection.

[0037] The upper and lower surfaces of the upper base plate 1 and the lower base plate 2 are both hinged with a plurality of groups of load-bearing frames 43 distributed in a circular array. The number of the load-bearing frames 43 corresponds to the number of the positioning columns 42, and the load-bearing frames 43 are provided with movable openings 44 for movably cooperating with the positioning columns 42. Positioning claws 45 are installed at one end of the two corresponding upper and lower load-bearing frames 43. The positioning claws 45 are made of wear-resistant and non-slip materials to ensure good friction with the surface of the pipe pile and can effectively clamp the pipe pile. A connecting beam 46 is installed on the movable ring 41, and the connecting beam 46 is fixedly connected to the movable ring 41, and the connecting beam 46 is driven by the A electric cylinder 47.

[0038] When the A electric cylinder 47 on the upper base plate 1 and the lower base plate 2 is started, the piston rod of the A electric cylinder 47 extends or retracts, driving the connecting beam 46 to move. Since the connecting beam 46 is fixed to the movable ring 41, the movable ring 41 rotates. During the rotation of the movable ring 41, the positioning column 42 rotates with the movable ring 41, and the positioning column 42 moves in the movable opening 44 on the load-bearing frame 43, forcing the load-bearing frame 43 to rotate around its hinge point with the base plate, so that the positioning claws 45 on the upper and lower corresponding load-bearing frames 43 gradually approach the pipe pile, and finally clamp the pipe pile. It should be noted that the two ends of the A electric cylinder 47 on the upper base plate 1 are respectively connected to the connecting beam 46 and the upper base plate 1 by a hinged manner, and the two ends of the A electric cylinder 47 on the lower base plate 2 are also respectively connected to the connecting beam 46 and the lower base plate 2 by a hinged manner. This hinged manner can ensure that during the driving process of the A electric cylinder 47, the movement of the connecting beam 46 and the movable ring 41 is smoother, avoiding stress concentration and motion interference caused by rigid connection.

[0039] See also Figure 4 The ring cutting structure 5 includes a turntable bearing 51, a fixed ring 52, a movable beam 53, a cutting saw blade 54, a B electric cylinder 55, a tooth groove 56 and a gear 57. The turntable bearing 51 is arranged on the top of the lower base plate 2 and is distributed around the cutting circular opening. Its outer ring is fixedly connected to the lower base plate 2, and its inner ring is fixedly connected to the fixed ring 52, so that the fixed ring 52 can rotate smoothly relative to the lower base plate 2 through the turntable bearing 51. The inner side of the fixed ring 52 is hinged with a movable beam 53 by means of a pin shaft, etc., and the other end of the movable beam 53 is installed with a cutting saw blade 54. The cutting saw blade 54 is driven by a special motor to rotate at a high speed to achieve cutting of the pipe pile. The inner side of the fixed ring 52 is also hinged with a B electric cylinder 55, and the other end of the B electric cylinder 55 is hinged to the side of the movable beam 53. A tooth groove 56 is arranged on the outer side of the fixed ring 52, and a rotatable gear 57 is installed on the lower base plate 2. The gear 57 is meshed with the tooth groove 56 on the fixed ring 52, and the gear 57 is driven to rotate by the motor.

[0040] When the pipe pile needs to be circumcised, the motor driving the gear 57 is first started, and the gear 57 rotates, driving the fixed ring 52 to rotate around the central axis of the turntable bearing 51 through the tooth groove 56. At the same time, the B electric cylinder 55 is started, and the piston rod of the B electric cylinder 55 is extended and retracted, pushing the movable beam 53 to rotate around its hinge point with the fixed ring 52, so that the cutting saw blade 54 gradually approaches the pipe pile. When the cutting saw blade 54 contacts the pipe pile, the motor driving the cutting saw blade 54 is started, and the high-speed rotating cutting saw blade 54 cuts a circular cutting along the side of the pipe pile as the fixed ring 52 rotates. By controlling the extension and retraction of the B electric cylinder 55, the contact pressure and cutting depth of the cutting saw blade 54 and the pipe pile can be accurately adjusted to ensure the flatness and quality of the cutting.

[0041] See also Figure 5The rope saw mechanism 6 is composed of two guide rails 61, a linear motor 62, a U-shaped frame 63, a guide wheel 64, a driving wheel 65 and a rope saw 66. The two guide rails 61 are installed in parallel on the lower base plate 2, and the U-shaped frame 63 is installed on the slider of the guide rail 61. The slide of the linear motor 62 is connected to the bottom of the U-shaped frame 63, and can drive the U-shaped frame 63 to move linearly along the guide rail 61. A plurality of guide wheels 64 and a driving wheel 65 are installed on the U-shaped frame 63, and a transmittable rope saw 66 is wound around the guide wheel 64 and the driving wheel 65. The driving wheel 65 is driven to rotate by the motor.

[0042] After the ring cutting structure 5 cuts a circle of notches on the side of the pipe pile, the linear motor 62 is started, and the slide of the linear motor 62 drives the U-shaped frame 63 to move forward along the guide rail 61, so that the rope saw 66 is close to the cutting opening on the pipe pile. At the same time, the motor driving the driving wheel 65 is started, and the driving wheel 65 rotates, driving the rope saw 66 to circulate on the guide wheel 64 and the driving wheel 65. Since the rope saw 66 has a certain degree of flexibility and toughness, it can perform deep cutting along the notch cut by the ring cutting structure 5 until the pipe pile is cut off. The setting of the guide wheel 64 can ensure the stability and guidance of the rope saw 66 during the movement, and prevent the rope saw 66 from being offset or twisted, which affects the cutting effect.

[0043] When the rope saw mechanism 6 is running, since the cutting positions of the rope saw mechanism 6 and the circular cutting structure 5 are in the same horizontal plane, they will interfere with each other. After the circular cutting structure 5 is circularly cut, it is necessary to move to the opposite side of the rope saw mechanism 6 and shrink the circular cutting structure 5 to avoid contact between the rope saw 66 and the circular cutting structure 5.

[0044] A ring cutting method for pipe pile production, the specific operation is as follows:

[0045] Preparation: First, insert the pipe pile into the cutting circular openings on the upper base plate 1 and the lower base plate 2 to ensure that the pipe pile is positioned accurately. Then, start the clamping structure 4 on the upper base plate 1 and the lower base plate 2, and drive the connecting beam 46 through the A electric cylinder 47 to rotate the movable ring 41, drive the positioning column 42 to move in the movable opening 44 of the load-bearing frame 43, and then rotate the load-bearing frame 43, so that the positioning claw 45 tightly clamps the side of the pipe pile to ensure that the pipe pile will not move during the cutting process. After the clamping is completed, use a rope to tie it to the pipe pile to be cut so that the cut pipe pile can be hoisted later.

[0046] Cutting process: Next, the ring cutting structure 5 is started. The motor of the driving gear 57 drives the gear 57 to rotate, and the fixed ring 52 rotates around the turntable bearing 51 through the tooth groove 56. At the same time, the B electric cylinder 55 is extended and pushed to push the movable beam 53, so that the cutting saw blade 54 contacts the pipe pile and cuts a circle of cutting openings along the side of the pipe pile. When the ring cutting is completed, the ring cutting structure 5 is controlled to move so that the cutting saw blade 54 moves to the opposite position of the rope saw mechanism 6. Then the rope saw mechanism 6 is started, and the linear motor 62 drives the U-shaped frame 63 to move forward along the guide rail 61. At the same time, the driving motor of the driving wheel 65 drives the driving wheel 65 to rotate, so that the rope saw 66 circulates on the guide wheel 64 and the driving wheel 65, and continues to cut along the existing cutting openings on the pipe pile until the pipe pile is cut off.

[0047] Subsequent operation: After the pipe pile is cut, the A electric cylinder 47 of the clamping structure 4 on the upper base plate 1 is stopped to release the pipe pile by the positioning claw 45. Finally, the cut pipe pile is lifted out by the lifting equipment through the rope pre-tied to the pipe pile, completing the entire pipe pile cutting operation process.
