[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] The cutting efficiency is low, and the cutting accuracy is also low.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0008] This disclosure provides a concrete pipe cutting device to improve cutting efficiency and accuracy.

[0009] In some embodiments, the concrete pipe cutting equipment includes: a support base, a support arm, a rotating arm, and an auxiliary support frame. The support base is rotatably equipped with two support rollers for supporting the concrete pipe; the support arm is slidably connected to the support base; the rotating arm is rotatably connected to the top end of the support arm, and a cutting machine is located at one end, above one of the support rollers; one end of the auxiliary support frame is slidably connected to the cutting machine, and the other end is equipped with a rotating wheel for contacting the concrete pipe.

[0010] Optionally, a limiting block is provided on one side of the cutting machine, the limiting block is rotatably connected to the rotating rod, and the auxiliary support frame is slidably connected to the rotating rod.

[0011] Optionally, the auxiliary support frame has a fork arm at one end facing away from the rotating rod, the fork arm has multiple rotating wheels, and a guide rod is fixedly installed on the fork arm.

[0012] Optionally, the support roller includes: a sliding shaft, a first sliding roller, and a second sliding roller. The two ends of the sliding shaft are rotatably connected to the support base; there are two first sliding rollers, each slidably connected to the sliding shaft; the second sliding roller is disposed between the two first sliding rollers and is slidably connected to the sliding shaft.

[0013] Optionally, the support roller further includes: a movable seat, an adjusting roller, and a belt. The movable seat is slidably disposed on the support seat and disposed below one of the first sliding rollers; two adjusting rollers are provided, both of which are slidably connected to the movable seat; the belt is slidably connected to the first groove on the first sliding roller and the second groove on the adjusting roller, and the belt can be positioned on the outside of the concrete pipe.

[0014] Optionally, both ends of the belt are fixedly connected to fixing blocks, and each fixing block is provided with a slot, which is inserted into the plug blocks at both ends of the soft belt.

[0015] Optionally, both adjusting rollers are slidably connected to the movable seat via roller seats, and the movable seat is rotatably provided with a bidirectional lead screw, the two ends of which are threadedly connected to the two roller seats respectively.

[0017] The concrete pipe cutting equipment provided in this disclosure can achieve the following technical effects:

[0018] The concrete pipe to be cut is placed on two support rollers, with the pipe's axis parallel to the rollers' axes. The rotation of the support rollers causes the concrete pipe to rotate, and the end of the rotating arm with the cutter faces the pipe until the cutter's blade contacts the outer wall of the pipe. The cutter then rotates relative to the pipe, cutting it without manual intervention, resulting in relatively high efficiency. Simultaneously, the rotating wheel on the auxiliary support frame rotates and abuts against the outer wall of the pipe, providing lateral support to the cutter and reducing the risk of wobbling during cutting. This lowers the risk of deviation and produces a smoother cut with relatively high precision.

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0036] Combination Figure 1As shown in the figure, this embodiment of the present disclosure provides a concrete pipe cutting device including: a support base 100, a support arm 200, a rotating arm 300, and an auxiliary support frame 400. The support base 100 is rotatably equipped with two support rollers 500, which are used to support the concrete pipe; the support arm 200 is slidably connected to the support base 100; the rotating arm 300 is rotatably connected to the top end of the support arm 200, and a cutting machine 600 is provided at one end, with the cutting machine 600 located above one of the support rollers 500; one end of the auxiliary support frame 400 is slidably connected to the cutting machine 600, and the other end is provided with a rotating wheel 410, which is used to abut against the concrete pipe.

[0037] Using the concrete pipe cutting equipment provided in this embodiment, the concrete pipe to be cut is placed on two support rollers 500, with the axis of the concrete pipe parallel to the axis of the support rollers 500. The rotation of the support rollers 500 causes the concrete pipe to rotate, and the end of the rotating arm 300 equipped with the cutting machine 600 rotates towards the concrete pipe until the cutting blade of the cutting machine 600 contacts the outer wall of the concrete pipe. The cutting machine 600 then rotates relative to the concrete pipe, cutting it without manual intervention, resulting in relatively high cutting efficiency. Simultaneously, the rotating wheel 410 on the auxiliary support frame 400 rotates and abuts against the outer wall of the concrete pipe, providing lateral support to the cutting machine 600, reducing the risk of wobbling during cutting, lowering the risk of cutting deviation, and producing a smoother cut with relatively high cutting precision.

[0038] Combination Figure 2 As shown, optionally, a base 210 is fixedly provided at the bottom of the support arm 200, and a guide groove 110 is provided on the support base 100. The base 210 is slidably connected to the guide groove 110. Specifically, a T-shaped guide rail is provided on the guide groove 110, and a T-shaped sliding groove that cooperates with the T-shaped guide rail is provided on the base 210. The base 210 is fitted onto the T-shaped guide rail through the T-shaped sliding groove. In practical applications, after the position of the base 210 is moved and adjusted, a set screw can be provided on the base 210 to improve its stability. The set screw presses against the bottom plane of the guide groove 110 to improve the stability of the base 210. In this way, the base 210 and the guide groove 110 cooperate to provide guidance for the sliding of the support arm 200. By adjusting the relative position of the base 210 and the support base 100, the position of the support arm 200 and the rotating arm 300 relative to the concrete pipe can be adjusted, allowing for flexible cutting of concrete pipes of different sizes according to construction requirements.

[0039] Understandably, the cutting machine 600 utilizes existing and conventional technologies. One side of the supporting main structure of the cutting machine 600 is fixedly connected to one end of the rotating arm 300, and both the cutting saw blade and the drive motor of the saw blade are mounted on its supporting main structure.

[0040] Combination Figure 3 As shown, optionally, a limiting block 610 is provided on one side of the cutting machine 600. The limiting block 610 is rotatably connected to the rotating rod 420, and the auxiliary support frame 400 is slidably connected to the rotating rod 420. In this way, the limiting block 610 provides a limit for the movement of the rotating rod 420 in the longitudinal and lateral directions, resulting in relatively high connection stability. When the rotating wheel 410 abuts against the concrete pipe, the auxiliary support frame 400 can slide relative to the rotating rod 420. After the cutting distance of the cutting machine 600 is adjusted, the auxiliary support frame 400 slides accordingly, and the rotating rod 420 rotates relative to the limiting block 610. This ensures that the rotating wheel 410 can tightly abut against the concrete pipe, thereby improving the lateral support effect on the cutting machine 600.

[0041] Optionally, two limit blocks 610 are provided, and both limit blocks 610 are rotatably connected to the rotating rod 420. In this way, the two limit blocks 610 cooperate with the rotating rod 420, and the connection stability is relatively high.

[0042] Optionally, the auxiliary support frame 400 has a fork arm 430 at one end facing away from the rotating rod 420. The fork arm 430 has multiple rotating wheels 410, and a guide rod 440 is fixedly mounted on the fork arm 430. In this way, before the concrete pipe is cut, the rotating wheels 410 are not in contact with the concrete pipe. As the cutting machine 600 moves toward the concrete pipe, the guide rod 440 first contacts the concrete pipe. As the cutting machine 600 continues to move, the concrete pipe slides relative to the guide rod 440, which drives the fork arm 430, the auxiliary support frame 400, and the rotating rod 420 to rotate, so that the rotating wheels 410 move toward the concrete pipe until the rotating wheels 410 abut against the concrete pipe.

[0043] Specifically, there are two rotating wheels 410. This results in a relatively large number of rotating wheels 410, and a relatively large number of contact points with the concrete pipe, which can provide better lateral support for the cutting machine 600.

[0044] Optionally, a spring 450 is fitted on the outer side of the auxiliary support frame 400, with one end of the spring 450 abutting against the rotating rod 420. The spring 450 provides elastic force for the auxiliary support frame 400 to slide away from the rotating rod 420. In this way, when the cutting machine 600 is cutting the concrete pipe, the spring 450 is compressed by the auxiliary support frame 400. After the cutting is completed, the cutting machine 600 moves away from the concrete pipe, and the spring 450 springs back to its original position, making it convenient to cut the concrete pipe again.

[0045] Combination Figure 4 , Figure 5 and Figure 6As shown, optionally, the support roller 500 includes: a sliding shaft 510, a first sliding roller 520, and a second sliding roller 530. The two ends of the sliding shaft 510 are rotatably connected to the support base 100; two first sliding rollers 520 are provided, each slidably connected to the sliding shaft 510; the second sliding roller 530 is disposed between the two first sliding rollers 520 and slidably connected to the sliding shaft 510. Thus, the first sliding rollers 520 and the second sliding rollers 530 abut against the concrete pipe, and the sliding shaft 510 rotates relative to the support base 100, thereby driving the first sliding rollers 520 and the second sliding rollers 530 to rotate, and consequently driving the concrete pipe to rotate. The first sliding roller 520 can slide relative to the sliding shaft 510. The interval between the two first sliding rollers 520 can be adjusted according to the length of the concrete pipe to better meet the needs of cutting the concrete pipe. Furthermore, after adjusting the positions of the first sliding roller 520 and the second sliding roller 530 on the sliding shaft 510, to improve the stability of the first sliding roller 520 and the second sliding roller 530 on the sliding shaft 510, a set screw can be provided on both the first sliding roller 520 and the second sliding roller 530. The pressing force of the set screw on the sliding shaft 510 is used to further position the first sliding roller 520 and the second sliding roller 530. If the interval between the first sliding roller 520 and the second sliding roller 530 is too large, the second sliding roller 530 can provide support for the concrete pipe between the two first sliding rollers 520, reducing the risk of deformation of the concrete pipe.

[0046] Optionally, two second sliding rollers 530 are provided. In this way, the number of second sliding rollers 530 is relatively large, the number of support positions is relatively large, and the support stability is better.

[0047] Understandably, the two support rollers 500 have the same structure, so I will not go into details here.

[0048] Optionally, a first motor 540 is provided on one side of the support base 100, and the output end of the first motor 540 is connected to one of the sliding shafts 510. In this way, the first motor 540 provides power for the rotation of the sliding shaft 510, and drives the concrete pipe to rotate through the first sliding roller 520 and the second sliding roller 530.

[0049] Optionally, the length of the sliding shaft 510 is greater than the length of the first sliding roller 520, and the length of the first sliding roller 520 is greater than the length of the second sliding roller 530. In this way, the length of the sliding shaft 510 is relatively long, and the length of the concrete pipe that can be cut is also relatively long.

[0050] Optionally, the support roller 500 further includes: a movable seat 550, an adjusting roller 560, and a belt 570. The movable seat 550 is slidably disposed on the support base 100 and is disposed below one of the first sliding rollers 520; two adjusting rollers 560 are provided, both slidably connected to the movable seat 550; the belt 570 is slidably connected to the first groove 521 on the first sliding roller 520 and the second groove 561 on the adjusting roller 560, and the belt 570 can be tightened around the outside of the concrete pipe. Thus, when the concrete pipe is placed on the first sliding roller 520, the belt 570 is fitted over the outside of the concrete pipe, and the belt 570 abuts against the first sliding roller 520 and the two adjusting rollers 560. The two adjusting rollers 560 then slide relative to the movable seat 550, causing the belt 570 to gradually tighten, thereby tightening the concrete pipe. The rotation of the first sliding roller 520 also drives the belt 570 to rotate, and the belt 570 can tighten the concrete pipe, reducing the risk of the concrete pipe falling off.

[0051] Understandably, the movable seat 550, adjusting roller 560 and belt 570 are provided in multiple sets. Each set has a movable seat 550, two adjusting rollers 560 and one belt 570. Each first support roller 500 is provided with a corresponding set and each second sliding roller 530 is provided with a corresponding set.

[0052] Optionally, a slider 551 is fixedly provided at the bottom of the movable seat 550, and a corresponding groove 120 is provided on the support seat 100, with the lower side wall of the slider 551 being higher than the bottom side wall of the groove 120. In this way, the groove 120 is relatively deep, and the risk of dust and debris in the concrete pipe falling into the groove 120 and interfering with the sliding of the slider 551 is relatively low.

[0053] Optionally, both ends of the belt 570 are fixedly connected to fixing blocks 571, and each fixing block 571 is provided with a slot 572. The slot 572 is inserted into the insert blocks 574 at both ends of the flexible belt 573. In this way, the insert blocks 574 can be pulled out from the slots 572, thereby removing the flexible belt 573 so that the belt 570 can be tied to the outside of the concrete pipe.

[0054] Optionally, both adjusting rollers 560 are slidably connected to the movable seat 550 via roller seats 562. A bidirectional lead screw 552 is rotatably mounted on the movable seat 550, and both ends of the bidirectional lead screw 552 are threadedly connected to the two roller seats 562 respectively. In this way, the rotation of the bidirectional lead screw 552 causes the two roller seats 562 to move closer or further apart, thereby loosening or tightening the belt 570.

[0055] Optionally, a second motor 553 is provided on one side of the movable seat 550, and the output end of the second motor 553 is connected to one end of the bidirectional lead screw 552. In this way, the second motor 553 provides power for the rotation of the bidirectional lead screw 552 to control the two roller seats 562 to move closer or further apart, thereby loosening or tensioning the belt 570.

[0056] Combination Figure 7 As shown, optionally, a counterweight box 310 is provided at one end of the rotating arm 300 facing away from the cutting machine 600. The bottom side of the counterweight box 310 is rotatably connected to the output end of the hydraulic cylinder 320, and the other end of the hydraulic cylinder 320 is rotatably connected to the support arm 200. In this way, the hydraulic cylinder 320 provides power for the rotation of the rotating arm 300 relative to the support arm 200. Furthermore, the counterweight box 310 balances the weight of the cutting machine 600, facilitating the rotation of the rotating arm 300 relative to the support arm 200.

[0057] Understandably, the hydraulic cylinder 320 is a three-section hydraulic cylinder, which is a current and conventional technology.

[0058] Specifically, the distance between the connection point of the rotating arm 300 and the support arm 200 and the cutting machine 600 is greater than the distance between the connection point and the counterweight box 310.
