Description

Technical Field

[0001] The invention relates to the technical field of pipeline cutting, and in particular to a cutting device for gas engineering pipeline installation. Background Art

[0002] As a pipeline system for the transportation of combustible gas, gas pipelines are mainly made of steel pipes and polyethylene pipes, and are laid underground or overhead. During installation, due to the complexity of the construction site, in order to adapt to the actual installation trajectory and connect pipes of different diameters, it is often necessary to cut the pipeline during the installation process to ensure the sealing performance of the pipeline after installation and ensure the safe and stable operation of the gas transportation system.

[0003] In the existing pipe cutting operation, one end of the pipe needs to be placed into the cutting equipment, and the cutting position needs to be adjusted before the cutting operation is carried out. If the cutting position is in the middle of the pipe, it is inconvenient to load the material, which affects the loading efficiency. If the cutting position is at the end of the pipe, the other end needs to be assisted by a supporting device. Otherwise, after the cutting is completed, the pipe will cause local stress concentration on the clamping part, which not only affects the service life of the clamping part, but also easily causes safety hazards. In addition, the supporting device needs to be adjusted according to the specifications of different pipes, which seriously affects the processing efficiency.

[0040] The clamping mechanism 1 44 comprises a docking seat 1 441 fixedly connected to the supporting seat 1 311, and the outer side of the docking seat 1 441 is symmetrically rotatably connected with a half gear ring 1 442 and a semicircular ring 1 443, and the half gear ring 1 442 and the semicircular ring 1 443 are symmetrically provided with circular grooves on one side close to the clamping mechanism 2 45, and the semicircular ring 1 443 is adapted to mesh with the gear 1 314;

[0041] The second clamping mechanism 45 includes a second docking seat 451 fixedly connected to the second dual-axis motor 322, and the outer side of the second docking seat 451 is symmetrically connected to a second half gear ring 452 and a second semicircular ring 453 for rotation, and the second half gear ring 452 and the second semicircular ring 453 are symmetrically fixedly connected to a fixed shaft 454 on one side close to the first clamping mechanism 44, and the second half gear ring 452 is adapted to mesh with the second gear 324;

[0042] The inside of the equipment base 1 is fixedly connected with a support block 42, the inner sides of the docking seat 1 441 and the docking seat 2 451 are fixedly connected with a fixing block 47, the positioning mechanism 43 is evenly arranged on the end close to the support block 42 and the two fixing blocks 47, and the laser cutting head 6 is fixedly connected between the two semicircular rings 2 453;

[0043] The bottoms of the docking seat 2 451 and the docking seat 1 441 are both fixedly connected with a fixing plate 48 , and the fixing plate 48 is slidably connected to the inside of the fixing block 47 .

[0044] In practical application, the embodiment of the present invention is as follows: Figures 1 to 3 As shown, firstly, the servo motor 2 on the equipment base 1 controls the transmission mechanism 46 to adjust the positions of the clamping mechanism 1 44 and the clamping mechanism 2 45, so as to adapt to gas engineering pipelines of different specifications and facilitate convenient clamping after subsequent loading;

[0045] like Figure 3 and Figure 5As shown, when the pipeline is manually placed between the clamping mechanism 1 44 and the clamping mechanism 2 45, the positioning mechanism 43 at the bottom and the support components 5 at both ends will achieve preliminary support for the pipeline, and preliminarily determine the approximate position of the pipeline in the clamping component 4, so that the clamping mechanism 1 44 and the clamping mechanism 2 45 are reset under the driving of the transmission mechanism 46, so that the pipeline is located between the three positioning mechanisms 43, and at this time, the docking seat 1 441 and the half gear ring 1 442 are docked and fixed at both ends of the support block 42, the half gear ring 1 442 and the half gear ring 2 452 are docked into a gear ring through the fixed shaft 454, and the semicircular ring 1 443 and the semicircular ring 2 453 are docked into a circular ring through the fixed shaft 454;

[0046] Then Figure 4 and Figure 5 As shown, the dual-axis motor 2 322 is started to drive the driving shaft 2 323 to rotate through the coupling. Since the gear 2 324 is meshed with the half gear ring 2 452, the driving shaft 2 323 can drive the half gear ring 2 452 to rotate synchronously. The half gear ring 2 452 drives the half gear ring 1 442 connected thereto to rotate synchronously and provides the power for the positioning mechanism 43 to position and clamp, thereby realizing the positioning and clamping of the pipeline between the three positioning mechanisms 43.

[0047] Then as Figure 1 , Figure 4 and Figure 5 As shown, the dual-axis motor 312 is started, so that the dual-axis motor 312 drives the gear 314 to rotate by driving the driving shaft 313, and the rotation of the gear 314 drives the semicircular ring 443 to rotate. Since the laser cutting head 6 is fixedly connected between the two semicircular rings 453, the semicircular ring 443 can drive the laser cutting head 6 to rotate synchronously, thereby evenly cutting the steel pipe.

[0048] like Figure 1 , Fig. 9 and Fig.10 As shown, the support assembly 5 includes a mounting base 51 fixedly connected to the inside of the equipment base 1, the mounting base 51 is slidably connected to a support base three 52 inside, the bottom of the support base three 52 is symmetrically fixedly connected to a connecting block 53, a spring three 54 is fixedly connected between the connecting block 53 and the inner wall of the mounting base 51, the inside of the mounting base 51 is slidably connected to a mounting sleeve 55 through a guide rail, the inside of the mounting sleeve 55 is slidably connected to a positioning block 57 through a guide block 56, the inside of the mounting sleeve 55 is rotatably connected to the positioning block 57, the positioning block 57 is threadedly connected to the outer side of the threaded rod two 58, and one end of the drive shaft one 313 located inside the threaded rod two 58 is symmetrically fixedly connected to a spring piece 59.

[0049] In actual application of the embodiment of the present invention, the support seat 3 52 of the support assembly 5 is in the initial position in the mounting seat 51, and the spring 3 54 is in a natural or pre-compressed state. When the pipeline is placed on the equipment base 1 and located between the clamping assemblies 4, the dead weight of the pipeline will cause the support seat 3 52 to slide downward in the mounting seat 51, and the spring 3 54 will be further compressed. At this time, the upward elastic force generated by the spring 3 54 plays a preliminary buffering and supporting role for the pipeline, and the support height is adaptively adjusted to meet the placement requirements of pipelines with different diameters. When the drive shaft 1 313 starts to rotate During movement, due to the rotation of the driving shaft 1 313, the spring piece 59 will push the threaded rod 2 58 to rotate inside the threaded rod 2 58. As the threaded rod 2 58 rotates, the positioning block 57 threadedly connected thereto will slide in the mounting sleeve 55 along the direction defined by the guide block 56. The sliding of the positioning block 57 will exert a force on the connecting block 53, overcoming the elastic force of the spring 3 54, achieving a predetermined position and locking, thereby ensuring that the pipeline can be stably and reliably supported during the cutting process, and effectively preventing problems such as pipeline displacement and deformation caused by unstable support.

[0050] like Figures 5 to 7 As shown, the positioning mechanism 43 includes a fixed seat 431, and a movable block 437 is slidably connected inside the fixed seat 431. A threaded rod 436 is also rotatably connected inside the fixed seat 431. One end of the threaded rod 436 is threadedly connected to the movable block 437, and the other end of the threaded rod 436 is fixedly connected to the driven wheel 433. The half gear ring 1 442 and the half gear ring 2 452 are both engaged with the driven wheel 433. The movable block 437 is symmetrically slidably connected to the connecting shaft 434. The two connecting shafts 434 are fixedly connected to the same block 432 at one end away from the fixed seat 431, and a spring 2 435 is fixedly connected between the connecting shaft 434 and the inner wall of the movable block 437.

[0051] In actual application of the embodiment of the present invention, when the half gear ring 1 442 is connected with the half gear ring 2 452 and starts to rotate under the drive of the dual-axis motor 2 322, since the half gear ring 1 442 and the half gear ring 2 452 are both engaged with the driven wheel 433, the driven wheel 433 will rotate accordingly, and the rotation of the driven wheel 433 drives the threaded rod 1 436 fixedly connected thereto to rotate synchronously. As the threaded rod 1 436 rotates, the movable block 1 437 threadedly connected thereto slides along a specific direction inside the fixed seat 431, and the movable block 1 437 slides. During the movement, the block 432 connected to it by the connecting shaft 434 will be driven to produce corresponding displacement. In the initial state, the spring 2 435 is in a certain pre-tightened or natural state. When the movable block 1 437 starts to move, the connecting shaft 434 will slide relatively inside the movable block 1 437, and the state of the spring 2 435 will also change. The elastic force generated by it will act on the connecting shaft 434 and the block 432, gradually approaching and finally fitting tightly to the outer surface of the pipe, thereby realizing the positioning and clamping of the pipe and ensuring the smooth progress of the cutting operation.

[0052] like Figures 2 to 6 As shown, the transmission mechanism 46 includes a movable block 461 symmetrically slidably connected to the equipment base 1, and the internal rotation of the equipment base 1 is connected with a bidirectional screw rod 462. The two movable blocks 461 are symmetrically threadedly connected to the outer sides of the bidirectional screw rod 462. The two movable blocks 461 are fixedly connected to the support seat 1 311 and the support seat 2 321 respectively, and the bidirectional screw rod 462 is fixedly connected to the output shaft of the servo motor 2 through a coupling.

[0053] In actual application of the embodiment of the present invention, when it is necessary to adjust the relative position of the support seat 1 311 and the support seat 2 321 in the driving assembly 3 to adapt to gas engineering pipelines of different lengths or to realize specific cutting path planning during the cutting process, the servo motor 2 is started, and the output shaft of the servo motor 2 rotates to drive the bidirectional screw rod 462 fixedly connected to it through the coupling to rotate. Since the two movable blocks 2 461 are respectively fixedly connected to the support seat 1 311 and the support seat 2 321 and are symmetrically threadedly connected to the outside of the bidirectional screw rod 462, the rotation of the bidirectional screw rod 462 The two movable blocks 461 will produce relative sliding motion along the axial direction of the bidirectional screw 462 in the equipment base 1. When the bidirectional screw 462 rotates forward, the two movable blocks 461 will move closer to or away from each other, thereby driving the support seat 1 311 and the support seat 2 321 and the clamping mechanism 1 44, the clamping mechanism 2 45 connected thereto and the related driving mechanism 1 31, the driving mechanism 2 32 components to perform synchronous relative position adjustment as a whole, thereby improving the versatility and automation of the equipment and reducing the tediousness and errors of manual adjustment.

[0054] like Figure 4 and Figure 8As shown, the limiting mechanism 41 includes a limiting mechanism 41 fixedly connected to the upper surface of the device base 1, a slider 412 is slidably connected inside the limiting mechanism 41, a spring 1 413 is symmetrically fixedly connected between the slider 412 and the inner wall of the limiting seat 411, and a clamping seat 414 is fixedly connected to the outer side of the support seat 1 311 and the support seat 2 321, and the top of the clamping seat 414 is slidably connected to the inside of the slider 412.

[0055] When the embodiment of the present invention is actually used, when the support seat 1 311 and the support seat 2 321 are moved by the driving of the transmission mechanism 46 and other related components, the clamping seat 414 fixedly connected thereto will also be displaced synchronously. Since the top of the clamping seat 414 is slidably connected to the inside of the slider 412, and the slider 412 is slidably connected to the inside of the limiting mechanism 41, and the spring 1 413 is symmetrically fixedly connected between the slider 412 and the inner wall of the limiting seat 411, when the clamping seat 414 moves, it will drive the slider 412 to slide accordingly in the limiting mechanism 41, thereby clamping the half gear ring 1 442 and the half gear ring 2 452, and preventing their rotation from affecting the subsequent positioning and clamping.
