Description
Technical Field
[0001] This utility model belongs to the field of pipe processing technology, specifically a pipe cutting device for the construction of heating pipe networks. Background Technology
[0002] As a core piece of equipment in the construction of heating pipe networks, the cutting device is specifically designed for the cutting and beveling of heating pipes made of carbon steel, stainless steel, and other materials. By integrating clamping and fixing components with a cutting actuator, it can perform cutting, beveling, and other processing operations on pipes of different specifications, thereby meeting the needs of construction scenarios such as heating pipe network laying, node connection, and emergency repair. This cutting device is widely used in projects such as urban centralized heating pipe network construction and renovation of old pipe networks.
[0003] However, the above-mentioned implementation methods still have the following problems. In terms of pipe cutting operations, most rely on the movement of a mobile cutting mechanism around the pipe to complete the circumferential cutting. This method requires frequent adjustments to the trajectory and position of the cutting head to adapt to the pipe size. Especially when dealing with large-diameter or extra-long pipes, the operation steps are cumbersome and the cut is prone to irregularity due to deviations in the movement of the mechanism. In terms of operational convenience, when multiple cuts are required for the pipe, in confined environments such as pipe trenches or high-altitude operations, a lot of manpower is required to move and flip the pipe. This is not only labor-intensive, but also prone to deviations in the cut due to pipe displacement. It is difficult to meet the needs of efficient and convenient construction and use, and it is difficult to adapt to diverse on-site construction needs. It cannot guarantee efficient and convenient cutting operations. Therefore, it needs to be improved. Utility Model Content
[0004] The purpose of this invention is to address the above-mentioned problems. This invention provides a pipe cutting device for the construction of heating pipe networks, which has the advantage of improving operational convenience.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a pipe cutting device for construction of a heating pipeline network, comprising a base plate, a support frame hinged to the left side of the top of the base plate, a servo motor fixedly installed on the left side of the front of the support frame, a cutting disc movably sleeved on the right side of the front of the support frame, a pull rod fixedly connected to the right side of the support frame, a connecting plate movably sleeved inside the base plate, a fixing seat fixedly installed on the front of the connecting plate, a support seat fixedly installed at the top of the fixing seat, and two arc-shaped fixing blocks fixedly connected inside the support seat. The inner end of each arc-shaped fixing block is movable. An arc-shaped connecting block is dynamically connected. A rubber pad is fixedly installed at the inner end of the arc-shaped connecting block. A handle is fixedly connected to the front of the arc-shaped connecting block. An arc-shaped limiting block is fixedly installed on the outer surface of the arc-shaped connecting block. The outer surface of the arc-shaped limiting block is movably connected to the inner surface of the arc-shaped fixed block. Slider blocks are fixedly installed on both the left and right sides of the arc-shaped fixed block. A support block is fixedly connected to the outer surface of the support base. The outer surface of the slider is movably connected to the inner surface of the support block. A fixing plate is fixedly installed at the inner end of the support block. A screw is threaded into the internal thread of the fixing plate. The outer surface of the screw is movably connected to the inner surface of the arc-shaped fixed block.
[0006] As a preferred embodiment of this utility model, a support plate is movably connected to the top of the base plate, and a positioning block is fixedly installed at the bottom of the support plate.
[0007] In a preferred embodiment of this invention, the outer surface of the positioning block is movably sleeved with the inner surface of the base plate, and the inner surface of the support plate is movably connected with the outer surface of the pull rod.
[0008] As a preferred embodiment of this utility model, a cylinder is fixedly installed inside the base plate, and a limit post is movably sleeved inside the cylinder.
[0009] As a preferred embodiment of this utility model, a reset spring is fixedly installed on the right side of the limiting post, and the right end of the reset spring is fixedly connected to the inner surface of the cylinder.
[0010] As a preferred embodiment of this utility model, a round rod is fixedly connected to the right side of the limiting post, the outer end of the round rod penetrates through the cylinder and extends to the outside of the cylinder, and a handle is fixedly connected to the right side of the round rod.
[0011] As a preferred embodiment of this utility model, a circular groove is provided on the right side of the connecting plate, and the inner surface of the circular groove is movably sleeved with the outer surface of the limiting post.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model features an arc-shaped fixing block, a screw, a gripping rod, and an arc-shaped connecting block. The operator rotates the screw to move the arc-shaped fixing block upwards, opening the pipe's fixation. After opening, the operator grips the gripping rod to rotate the arc-shaped connecting block, causing the pipe to rotate as well. After rotating the pipe, the screw is rotated again to fix it. Simultaneously, the cutting disc is operated to cut the pipe. The overall operation is convenient; circumferential cutting can be completed simply by rotating the pipe itself in conjunction with the cutting disc. Furthermore, it eliminates the need for frequent adjustments to the pull rod or moving heavy, large pipes, reducing the labor intensity of construction workers and making it suitable for confined spaces or outdoor construction scenarios in heating pipe networks.
[0013] 2. This utility model, by setting up a round rod, a limiting post, a return spring, and a connecting plate, allows the operator to move the round rod by holding the handle. During the movement of the round rod, the limiting post will also move, compressing the return spring. At this time, the limiting post will disengage from the round groove, opening the fixation, and the connecting plate can then move. During the movement of the connecting plate, the fixing seat and the support seat will also move together. At this time, the combination of the arc-shaped fixing block, the arc-shaped connecting block, and the rubber pad will also move accordingly, thus completing the adjustment of the clamping position. Regardless of the length of the pipe, a stable support point can be found by adjusting the clamping position, avoiding the problem of ineffective fixation due to differences in pipe length. It is compatible with various length specifications of thermal pipes. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] like Figures 1 to 5 As shown, this utility model provides a pipe cutting device for the construction of a heating pipeline network, including a base plate 1. A support frame 2 is hinged to the left side of the top of the base plate 1. A servo motor 3 is fixedly installed on the left side of the front of the support frame 2. A cutting disc 4 is movably sleeved on the right side of the front of the support frame 2. A pull rod 5 is fixedly connected to the right side of the support frame 2. A connecting plate 6 is movably sleeved inside the base plate 1. A fixing seat 7 is fixedly installed on the front of the connecting plate 6. A support seat 8 is fixedly installed at the top of the fixing seat 7. Two arc-shaped fixing blocks 9 are fixedly connected inside the support seat 8. An arc-shaped connecting block 10 is movably connected to the inner end of each arc-shaped fixing block 9. A rubber pad 11 is fixedly installed on the inner end of block 10. A handle 12 is fixedly connected to the front of arc-shaped connecting block 10. An arc-shaped limiting block 13 is fixedly installed on the outer surface of arc-shaped connecting block 10. The outer surface of arc-shaped limiting block 13 is movably connected to the inner surface of arc-shaped fixing block 9. Slider blocks 14 are fixedly installed on both the left and right sides of arc-shaped fixing block 9. A support block 15 is fixedly connected to the outer surface of support base 8. The outer surface of slider 14 is movably connected to the inner surface of support block 15. A fixing plate 16 is fixedly installed on the inner end of support block 15. A screw 17 is threaded into the inner thread of fixing plate 16. The outer surface of screw 17 is movably connected to the inner surface of arc-shaped fixing block 9.
[0018] During use, the operator places the pipe between two arc-shaped fixing blocks 9. By rotating the screw 17, a threaded force is generated, which moves the arc-shaped fixing blocks 9 downward. When the arc-shaped fixing blocks 9 move, they will move the arc-shaped connecting blocks 10. When the arc-shaped connecting blocks 10 move, they will move the rubber pads 11 together. The rubber pads 11 come into contact with the pipe and deform. The pipe is fixed by the compression of the two rubber pads 11. At this time, the servo motor 3 is started, and its output shaft drives the transmission wheel and transmission belt to rotate, which in turn drives the cutting disc 4 to rotate. The operator holds the pull rod 5 and moves the cutting disc 4 downward to cut the pipe.
[0019] Among them, the top of the base plate 1 is movably connected to the support plate 18, and the bottom of the support plate 18 is fixedly installed with the positioning block 19.
[0020] When the support plate 18 moves, it is limited by the positioning block 19 so that it moves along a preset trajectory.
[0021] The outer surface of the positioning block 19 is movably sleeved with the inner surface of the base plate 1, and the inner surface of the support plate 18 is movably connected with the outer surface of the pull rod 5.
[0022] When not in use, the cutting disc 4 is positioned below the pull rod 5 by moving the support plate 18 to hold the pull rod 5.
[0023] The base plate 1 has a cylinder 20 fixedly installed inside, and the cylinder 20 is movably fitted with a limit post 21.
[0024] The limiting post 21 is connected to the connecting plate 6, thereby fixing the base plate 1 and the connecting plate 6.
[0025] A reset spring 22 is fixedly installed on the right side of the limiting post 21, and the right end of the reset spring 22 is fixedly connected to the inner surface of the cylinder 20.
[0026] During the movement of the limiting post 21, the return spring 22 will be compressed, and the return spring 22 will deform after being compressed.
[0027] Among them, a round rod 23 is fixedly connected to the right side of the limiting post 21. The outer end of the round rod 23 passes through the cylinder 20 and extends to the outside of the cylinder 20. A handle 24 is fixedly connected to the right side of the round rod 23.
[0028] The operator holds the handle 24 and moves the round rod 23. When the round rod 23 moves, it will move the limit post 21.
[0029] The connecting plate 6 has a circular groove 25 on its right side, and the inner surface of the circular groove 25 is movably connected to the outer surface of the limiting post 21.
[0030] As the limiting post 21 moves to the right, it will disengage from the circular groove 25, thus releasing the fixation between the base plate 1 and the connecting plate 6.
[0031] Working principle and usage process of this utility model: During use, the operator places the pipe between two arc-shaped fixing blocks 9. Rotating the screw 17 generates a threaded force that moves the arc-shaped fixing blocks 9 downwards. As the arc-shaped fixing blocks 9 move, they move the arc-shaped connecting blocks 10, which in turn moves the rubber pads 11. The rubber pads 11 come into contact with the pipe and deform, thus fixing the pipe under the pressure of the two rubber pads 11. At this point, the servo motor 3 is activated, its output shaft driving the transmission wheel and belt to rotate, which in turn drives the cutting disc 4 to rotate. The operator then holds the pull rod 5, causing the cutting disc 4 to move downwards to cut the pipe. When cutting large pipes, it is impossible to cut them all at once. In this case, the operator rotates the screw 17 to move the arc-shaped fixing block 9 upward, opening the fixation on the pipe. After opening the fixation, the operator holds the handle 12 to rotate the arc-shaped connecting block 10. The arc-shaped connecting block 10 is stabilized during rotation by the arc-shaped limiting block 13. When the arc-shaped connecting block 10 rotates, it will drive the pipe to rotate together. After the pipe is rotated, the screw 17 is rotated to fix it. At the same time, the cutting disc 4 is operated to complete the cutting of the pipe. The overall operation is convenient. The circumferential cutting can be completed by the rotation of the pipe itself and the cutting disc 4.
[0032] When the pipe lengths are different, the clamping position needs to be adjusted. The operator holds the handle 24 and moves the round rod 23. During the movement of the round rod 23, the limiting post 21 will move together, compressing the return spring 22. At this time, the limiting post 21 will disengage from the round groove 25, opening the fixation. The connecting plate 6 can then move. During the movement of the connecting plate 6, the fixing seat 7 and the support seat 8 will move together. At this time, the combination of the arc-shaped fixing block 9, the arc-shaped connecting block 10 and the rubber pad 11 will also move accordingly. The clamping position is then adjusted. The entire system can find a stable support point by adjusting the clamping position.
