Description

Technical Field

[0001] This utility model relates to the field of pipe manufacturing technology, and more specifically, to a transfer cutting device. Background Technology

[0002] In the field of modern pipeline engineering, large-diameter pipelines are widely used in key scenarios such as municipal water supply and drainage, urban centralized heating, long-distance oil and gas transportation, industrial circulating water transportation, and agricultural irrigation main pipelines. With the acceleration of urbanization, the expansion of large-scale industrial projects, and the surge in demand for infrastructure upgrades, traditional pipeline materials (such as metal pipes, pure plastic pipes, and ordinary composite pipes) are gradually revealing their performance shortcomings. Various types of high-strength steel wire mesh reinforced composite pipes, with their composite advantages of "metal skeleton reinforcement + corrosion resistance of polymer materials," have become an important development direction for large-diameter pipelines. Due to their larger diameter, multiple composite layers, and the inclusion of a metal mesh skeleton, these large-diameter pipelines are not only stronger but also very heavy. Furthermore, existing pipe cutting equipment generally only cuts the pipe, and there is a lack of equipment for axial cutting of the pipe's sides. For large-diameter composite pipes with high body strength, the requirements for cutting equipment are high. Directly using existing ordinary cutting equipment results in poor cutting effects and makes it difficult to guarantee cutting accuracy. Existing ordinary cutting equipment is not suitable for cutting large-diameter composite pipes and cannot meet the axial cutting requirements of this type of pipe. Utility Model Content

[0003] To overcome the shortcomings of the prior art in lacking equipment suitable for axial cutting of large-diameter composite pipes, this utility model provides a transfer cutting device to meet the cutting needs of large-diameter composite pipes.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a transfer cutting device, comprising: a fixed bracket, a clamping assembly disposed on the fixed bracket, a transfer assembly disposed on the top of the fixed bracket, and a cutting assembly disposed on the moving end of the transfer assembly. The clamping assembly is used to clamp the pipe from both sides. The transfer assembly includes a transverse bracket disposed on the top of the fixed bracket, at least two guide rails disposed on the transverse bracket, a support plate slidably connected to the guide rails, and a first driving assembly disposed on the support plate. The driving end of the first driving assembly is connected to the fixed bracket or the transverse bracket. The first driving assembly is used to drive the support plate to move. The cutting assembly is mounted on the support plate.

[0005] The clamping assembly is located on the upper part of the fixed bracket. When cutting the pipe, the clamping assembly clamps the pipe from both sides, preventing the pipe from rolling left and right and reducing its own vibration, thereby indirectly improving the pipe cutting accuracy. The transfer assembly is used to drive the cutting assembly to move and cut. The transfer assembly moves axially to cut the top and side of the pipe. The cutting assembly is located at the top. When performing axial cutting, cutting from the top avoids the cutting assembly being pressed by the pipe, preventing the pipe from pressing down and affecting the cutting assembly, and also allows for better observation of the working status of the cutting assembly. In the transfer assembly, the two ends of the horizontal bracket are supported on the fixed bracket. The support plate moves relative to the guide rail. At least two guide rails are set to ensure the stability and accuracy of the cutting assembly's movement. When the first drive assembly is working, it drives itself, the support plate, the cutting assembly, and other components to move together. The first drive assembly preferably uses a gear and rack structure for driving.

[0006] Preferably, the first drive assembly includes a geared motor disposed on the support plate, a transmission gear disposed on the output shaft of the geared motor, and a transmission rack fixedly connected to the transverse bracket, wherein the transmission gear meshes with the transmission rack.

[0007] A stable low-speed, high-torque motor is provided, while smooth transmission is achieved through transmission gears and racks.

[0008] Preferably, the output shaft of the geared motor passes through the support plate and is positioned towards the ground, and the teeth of the transmission rack mesh with the transmission gear on the side.

[0009] The output shaft of the geared motor is set vertically towards the ground, and the transmission rack is set on the side of the transmission gear rather than underneath it, so that the meshing effect of the transmission gear and the transmission rack is better.

[0010] Preferably, the clamping assembly includes a fixed plate disposed on the fixed bracket, a movable frame slidably connected to the fixed plate, a second drive assembly connected to the fixed plate, a telescopic member disposed on the movable frame, a clamping bracket disposed on the telescopic end of the telescopic member, a clamping block slidably connected vertically to the clamping bracket, and a fixing member connected to the clamping block. The second drive assembly has a locking function and is used to drive the movable frame to move. The fixing member is used to fix the clamping block on the clamping bracket. The clamping assembly is symmetrically disposed on both sides of the fixed bracket.

[0011] The clamping components are symmetrically arranged on both sides of the fixed bracket. The clamping components on both sides are used in groups and work synchronously. The telescopic component drives the clamping block to extend and clamp the pipe. The second drive component is used to drive the moving frame to move, which in turn drives the clamping block to move and adjust. When the clamping bracket moves relative to the telescopic component, it can also drive the clamping block to move, thereby realizing the adjustment of the clamping block in two directions to meet the clamping of pipes of different sizes. The second drive component has a locking function, that is, the driving end of the second drive component can be locked after moving, so that the moving frame and clamping block and other components can remain fixed after the position is adjusted. The specific structure can refer to the existing transfer equipment, or a trapezoidal screw with a self-locking function can be used for transmission.

[0012] Preferably, the second drive assembly includes a trapezoidal lead screw rotatably connected to the fixed plate, a drive component connected to the trapezoidal lead screw, and a slider mounted on the trapezoidal lead screw. The slider is fixedly connected to the movable frame, and the trapezoidal lead screw is axially fixed relative to the fixed plate.

[0013] A trapezoidal lead screw is used for transmission to achieve self-locking after the moving frame moves, reducing the requirements for the selection of the drive component. The drive component drives the trapezoidal lead screw to rotate relative to the fixed plate, and the slider is restricted on the moving frame. Since the trapezoidal lead screw is axially fixed relative to the fixed plate, rotation can drive the slider and the moving frame to move. The drive component can be a motor or a handwheel.

[0014] Preferably, the clamping assembly further includes a screw fixedly connected to the clamping bracket, a connecting plate and a handle respectively connected to the clamping block, the fixing member being a nut matching the screw, the connecting plate being fitted onto the screw and slidably connected to the screw, and the fixing member being provided at both the upper and lower positions of the connecting plate to fix the connecting plate.

[0015] The nuts are threaded onto the screw rod. Tightening the two nuts, one at the top and one at the bottom of the connecting plate, secures the connecting plate to the screw rod. A handle allows for easy lifting and adjustment of the clamping block. Before lifting the clamping block, loosen the nuts at the top and bottom of the connecting plate, lift the clamping block to the set position, and then tighten the nuts. This nut-based fixation effectively prevents the clamping block from wobbling, ensuring a secure clamping effect. Furthermore, height markings are provided on the clamping bracket to indicate the clamping position for different pipe diameters, facilitating position adjustment. These height markings can use standard position indicators or distance scales. Finally, the clamping surface of the clamping block is V-shaped.

[0016] Preferably, the cutting assembly includes a drive motor and a reducer respectively disposed on the moving end of the transfer assembly, a transmission assembly connected to the drive end of the drive motor, and a cutter disc disposed on the output end of the reducer, wherein the output end of the transmission assembly is connected to the input end of the reducer.

[0017] The drive motor drives the transmission assembly, which in turn drives the reducer, which in turn drives the cutter head. The reducer is preferably a single-stage horizontal cycloidal pinwheel reducer. The transmission assembly uses either a chain and sprocket structure or a belt and pulley structure, with a belt and pulley structure being preferred.

[0018] Preferably, the transmission assembly includes pulleys respectively disposed on the drive end of the drive motor and the input end of the reducer, and a transmission belt fitted on the pulleys.

[0019] The cutting assembly uses pulleys and a drive belt for power transmission. During operation, the cutting assembly is subjected to significant impact and vibration forces, which can adversely affect the equipment. Belt drive effectively reduces these impact and vibration forces, achieving a better shock absorption effect. This is because belts have a certain degree of elasticity, which can absorb impact and vibration forces. Furthermore, the tensioning device in the belt drive can adjust the belt tension to maintain normal operation of the transmission.

[0020] Preferably, the cutting assembly further includes a protective cover that is fixedly connected at both ends to the drive motor and the reducer, respectively, and the protective cover is used to protect the pulley and the transmission belt.

[0021] The protective cover completely encloses the drive belt and pulleys, providing protection.

[0022] Preferably, it also includes a limiting frame disposed on the fixed bracket and used to limit the end of the pipe, the limiting frame being vertically arranged and having a clearance portion for avoiding the cutting assembly.

[0023] The limiting frame is fixedly connected to the fixed bracket. During cutting, the end of the pipe abuts against the limiting frame for cutting. The limiting bracket has a clearance treatment for the cutting component, that is, a clearance part is set up so that the cutting component will not cut the limiting bracket when it moves.

[0024] Compared with the prior art, the beneficial effects of this utility model are: The structural design of the transfer component provides a stable and reliable moving structure for the cutting component, ensuring stable linear movement. Simultaneously, the clamping component clamps and fixes the pipe from both sides, significantly reducing vibration and deviation during cutting. Furthermore, placing the cutting component on top of the fixed support eliminates pressure from the pipe on the cutting component, reducing external interference and further improving cutting accuracy, thus meeting the cutting requirements of heavy-duty composite pipes.

To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.

In the description of this utility model, it should be understood that if terms such as "upper," "lower," "left," "right," "long," and "short" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0029] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings: Example 1 like Figure 1-2 As shown, a transfer cutting device includes: a fixed bracket 1, a clamping assembly 2 disposed on the fixed bracket 1, a transfer assembly 3 disposed on the top of the fixed bracket 1, and a cutting assembly 4 disposed on the moving end of the transfer assembly 3. The clamping assembly 2 is used to clamp the pipe from both sides, such as... Figure 5 As shown, the transfer assembly 3 includes a transverse support 301 disposed on the top of the fixed support 1, at least two guide rails 302 disposed on the transverse support 301, a support plate 303 slidably connected to the guide rails 302, and a first drive assembly 304 disposed on the support plate 303. The drive end of the first drive assembly 304 is connected to the fixed support 1 or the transverse support 301. The first drive assembly 304 is used to drive the support plate 303 to move. The cutting assembly 4 is mounted on the support plate 303.

[0030] The clamping assembly 2 is located on the upper part of the fixed bracket 1. When cutting the pipe, the clamping assembly 2 clamps the pipe from both sides to prevent the pipe from rolling left and right and to reduce the vibration of the pipe itself, thereby indirectly improving the cutting accuracy. The transfer assembly 3 is used to drive the cutting assembly 4 to move and cut. The transfer assembly 3 moves axially to cut the top and side of the pipe. The cutting assembly 4 is located at the top. When performing axial cutting, cutting from the top can prevent the cutting assembly 4 from being pressed by the pipe, prevent the pipe from pressing down, avoid affecting the cutting assembly 4, and also make it easier to observe the working status of the cutting assembly 4. In the transfer assembly 3, the transverse bracket 301 is supported on the fixed bracket 1 at both ends. The support plate 303 moves relative to the guide rail 302. At least two guide rails 302 are set to ensure the stability and accuracy of the movement of the cutting assembly 4. When the first drive assembly 304 is working, it drives the first drive assembly 304 itself, the support plate 303, the cutting assembly 4 and other components to move together. The first drive assembly 304 preferably adopts a gear and rack structure for driving.

[0031] The beneficial effects of this embodiment are as follows: the structural design of the transfer component 3 provides a stable and reliable moving structure for the cutting component 4, which can ensure the stable linear movement of the cutting component 4. At the same time, the clamping component 2 clamps and fixes the pipe from both sides, which can greatly reduce the vibration and displacement of the pipe during cutting. Furthermore, placing the cutting component 4 on the top of the fixed bracket 1 can eliminate the squeezing of the cutting component 4 by the pipe, reduce external force interference, further improve cutting accuracy, and meet the cutting requirements of heavy composite pipes.

[0032] Example 2 This embodiment further defines the features of Embodiment 1, and its difference from Embodiment 1 lies in: like Figure 6 As shown, the first drive assembly 304 includes a reduction motor 3041 mounted on the support plate 303, a transmission gear 3042 mounted on the output shaft of the reduction motor 3041, and a transmission rack 3043 fixedly connected to the transverse bracket 301. The transmission gear 3042 meshes with the transmission rack 3043. The output shaft of the reduction motor 3041 passes through the support plate 303 and faces towards the ground. The teeth of the transmission rack 3043 mesh with the transmission gear 3042 on its side. Figure 3-4As shown, the clamping assembly 2 includes a fixed plate 201 disposed on the fixed bracket 1, a movable frame 202 slidably connected to the fixed plate 201, a second drive assembly 203 connected to the fixed plate 201, a telescopic member 204 disposed on the movable frame 202, a clamping bracket 205 disposed on the telescopic end of the telescopic member 204, a clamping block 206 vertically slidably connected to the clamping bracket 205, and a fixing member 207 connected to the clamping block 206. The second drive assembly 203 has a locking function and is used to drive the movable frame 202 to move. The fixing member 207 is used to fix the clamping block 206 on the clamping bracket 205. The clamping assembly 2 is symmetrically disposed on both sides of the fixed bracket 1. The second driving assembly 203 includes a trapezoidal lead screw 2031 rotatably connected to the fixed plate 201, a driving member 2032 connected to the trapezoidal lead screw 2031, and a slider fitted on the trapezoidal lead screw 2031. The slider is fixedly connected to the moving frame 202, and the trapezoidal lead screw 2031 is axially fixed relative to the fixed plate 201. The clamping assembly 2 also includes a screw 208 fixedly connected to the clamping bracket 205, a connecting plate 209 and a handle 210 respectively connected to the clamping block 206. The fixing member 207 is a nut that matches the screw 208. The connecting plate 209 is fitted on the screw 208 and slidably connected to the screw 208. The fixing member 207 is provided at both the upper and lower positions of the connecting plate 209 to fix the connecting plate 209.

[0033] The geared motor 3041 provides stable low-speed, high-torque transmission, while the transmission gear 3042 and transmission rack 3043 achieve smooth transmission. The output shaft of the geared motor 3041 is vertically oriented towards the ground, and the transmission rack 3043 is positioned to the side of the transmission gear 3042 rather than underneath it, resulting in better meshing between the transmission gear 3042 and the transmission rack 3043. The clamping components 2 are symmetrically arranged on both sides of the fixed bracket 1. The clamping components 2 on both sides are used in groups and work synchronously. The telescopic component 204 drives the clamping block 206 to extend and clamp the pipe. The second drive component 203 is used to drive the moving frame 202 to move and thus drive the clamping block 206 to move and adjust. When the clamping bracket 205 moves relative to the telescopic component 204, it can also drive the clamping block 206 to move, thereby realizing the adjustment of the clamping block 206 in two directions to meet the clamping of pipes of different sizes. The second drive component 203 has a locking function, that is, the driving end of the second drive component 203 can be locked after moving, so that the moving frame 202 and the clamping block 206 can remain fixed after the position is adjusted. The specific structure can refer to the existing transfer equipment, or a trapezoidal screw 208 with a self-locking function can be used for transmission. A trapezoidal lead screw 2031 is used for transmission to achieve self-locking after the moving frame 202 moves, reducing the selection requirements of the drive component 2032. The drive component 2032 drives the trapezoidal lead screw 2031 to rotate relative to the fixed plate 201. The slider is restricted on the moving frame 202, and the trapezoidal lead screw 2031 is axially fixed relative to the fixed plate 201. Therefore, rotation can drive the slider and the moving frame 202 to move. The drive component 2032 can be a motor or a handwheel. The nut is threaded to the screw 208. The two nuts are tightened relative to each other at the upper and lower positions of the connecting plate 209 to fix the connecting plate 209 to the screw 208. The handle 210 is provided to facilitate lifting and adjusting the position of the clamping block 206. Before lifting the clamping block 206, first loosen the nuts located at the upper and lower positions of the connecting plate 209, then lift the clamping block 206 to the set position, and then tighten the nuts. The use of nuts for fixation can effectively prevent the clamping block 206 from shaking and ensure the clamping effect. Furthermore, a height mark is provided on the clamping bracket 205 to mark the height of the clamping position for different pipe diameters, facilitating the position adjustment of the clamping block 206. The height mark can be a general position mark or a distance scale. Furthermore, the clamping surface of the clamping block 206 is V-shaped.

[0034] The remaining features and working principles of this embodiment are the same as those of Embodiment 1.

[0035] Example 3 Based on Example 1 or Example 2, Example 1 or Example 2 are further defined, with the following differences: like Figure 7-8As shown, the cutting assembly 4 includes a drive motor 401 and a reducer 402 respectively disposed on the moving end of the transfer assembly 3, a transmission assembly 403 connected to the drive end of the drive motor 401, and a cutter disc 404 disposed on the output end of the reducer 402. The output end of the transmission assembly 403 is connected to the input end of the reducer 402. The transmission assembly 403 includes pulleys 4031 respectively disposed on the drive end of the drive motor 401 and the input end of the reducer 402, and a transmission belt 4032 fitted on the pulleys 4031. The cutting assembly 4 also includes a protective cover 405 fixedly connected at both ends to the drive motor 401 and the reducer 402, the protective cover 405 being used to protect the pulleys 4031 and the transmission belt 4032. Figure 1-2 As shown, it also includes a limiting frame 101 disposed on the fixed bracket 1 and used to limit the end of the pipe. The limiting frame 101 is vertically disposed and has a clearance portion 102 for avoiding the cutting component 4.

[0036] The drive motor 401 drives the transmission assembly 403, which in turn drives the reducer 402, which in turn drives the cutter head 404. The reducer 402 is preferably a single-stage horizontal cycloidal pinwheel reducer. The transmission assembly 403 uses either a chain and sprocket structure or a belt and pulley 4031 structure, with the belt and pulley 4031 structure being preferred. The cutting assembly 4 uses pulley 4031 and a drive belt 4032 for transmission. The cutting assembly 4 needs to withstand significant impact and vibration during operation, which can adversely affect the equipment. Belt drive effectively reduces impact and vibration, achieving better shock absorption. This is because belts have a certain degree of elasticity, absorbing impact and vibration, and the tensioning device in the belt drive can adjust the belt tension to maintain normal transmission operation. The protective cover 405 completely encloses the drive belt 4032 and pulley 4031, providing protection. The limiting frame 101 is fixedly connected to the fixed bracket 1. During cutting, the end of the pipe abuts against the limiting frame 101 for cutting. The limiting bracket has a clearance treatment for the cutting component 4, that is, a clearance part 102 is set up so that the cutting component 4 will not cut the limiting bracket when it moves.

[0037] like Figure 1 As shown in this embodiment, the fixed bracket 1 is provided with a pipe feed port 103 on the side away from the limit frame 101. The pipe can be moved and fed by ordinary pipe moving equipment, or a ground track can be laid and a transfer trolley can be used for feeding. When the pipe is fed, the pipe axis is parallel to the moving path of the cutting component 4.

[0038] The remaining working principles and processes of this embodiment are the same as those of Embodiment 1 or Embodiment 2.

[0039] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0040] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
