[0002] An oil and gas field refers to the sum of oil reservoirs, gas reservoirs, and oil and gas reservoirs within the same area controlled by a single local structural unit. If there are only oil reservoirs within this local structural range, it is called an oil field; if there are only gas reservoirs, it is called a gas field. During the construction of the oil and gas field, in order to facilitate the transportation of the collected oil and gas, it is often necessary to lay pipelines. When laying pipelines, in order to obtain pipelines of appropriate length, it is often necessary to use cutting devices to cut the pipelines.

[0003] After searching, the Chinese patent publication number is CN219685113U, which discloses a hydraulic cutting device for oil and gas pipelines, including a workbench with a working groove on the top of the workbench. Two placing devices are fixed on the inner lower surface of the working groove, and a rectangular groove is opened on the inner lower surface of the working groove between the two placing devices.

[0004] The prior art is similar to the above-mentioned oil and gas pipeline cutting device, but it requires manual adjustment of the position of the pipeline after each cutting before cutting again, which is not only troublesome to operate, but also seriously reduces the efficiency of continuous pipeline cutting.

[0005] Therefore, it is desired in the art to provide a pipe cutting device to solve the above technical problems. Utility Model Content

[0006] The utility model aims to provide a pipe cutting device, which can drive a screw rod to rotate forward or reversely by a first motor so that a clamping member slides along the length direction of a first through slot, thereby realizing automatic adjustment of the position of the pipe.

[0007] According to the utility model, a pipeline cutting device is provided, comprising a cutting disc for cutting a pipeline, and

[0008] A clamping mechanism adapted to the cutting disc, the clamping mechanism comprising a feeding platform and a first through slot formed in the feeding platform and accommodating a screw rod,

[0009] The clamping mechanism further includes a clamping member sleeved outside the screw rod and used to clamp the pipe, and a first motor disposed at the first end of the feeding platform and adapted to the screw rod.

[0010] The screw rod can rotate under the driving action of the first motor, thereby allowing the clamping member to drive the pipe to move along the length direction of the first through slot.

[0011] In one embodiment, the clamping member includes a body configured as a T-shaped structure, and a clamping assembly disposed on the body.

[0012] In one embodiment, a second through groove is formed at the upper end surface of the body.

[0013] The clamping assembly includes a bidirectional threaded rod arranged in the second through groove, a pair of spaced-apart clamping rings adapted to the bidirectional threaded rod, and an electrical control box arranged outside the main body and adapted to the bidirectional threaded rod, wherein the two clamping rings can move toward each other or away from each other under the action of the electrical control box.

[0014] In one embodiment, the clamping ring is constructed as a semi-annular structure, and anti-slip convex particles are provided on the inner wall surface of the clamping ring.

[0015] In one embodiment, the cross-section of the anti-slip convex particles is a semicircular structure.

[0016] In one embodiment, the pipe cutting device further comprises a base fixed to the lower end surface of the feeding platform.

[0017] In one embodiment, the clamping mechanism further comprises a first fixing ring disposed at the second end of the feeding platform and used to fix the pipeline.

[0018] A gantry is also provided on the base, and a second fixing ring matched with the first fixing ring is provided on the gantry.

[0023] First, the utility model can drive the screw rod to rotate forward or reversely by the first motor, so that the clamping member slides along the length direction of the first through slot, thereby realizing automatic adjustment of the position of the pipeline. It can be seen that the utility model does not need manual adjustment of the pipeline, thereby not only reducing labor costs but also effectively improving the efficiency of continuous cutting of the pipeline.

[0024] Secondly, the utility model can play a dual fixing and clamping role on the pipeline through the clamping ring and the clamping ring and the first fixing ring and the second fixing ring, thereby not only ensuring the stability of the pipeline during the cutting process, but also effectively avoiding the damage caused by the shaking of the pipeline during the cutting process.

[0025] Thirdly, the utility model can smoothly adjust the position of the pipe according to the required length of the pipe by setting an extension hole on the fixing plate. In other words, when the pipe to be cut is short, it can be fixed by using the clamping ring and the clamping ring and the first fixing ring and the second fixing ring 25; when the pipe to be cut is long, the head of the pipe is passed outward through the extension hole, which can solve the problem of cutting caused by the long pipe.

[0031] In order to make the technical solutions and advantages of the present invention more clearly understood, the exemplary embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than an exhaustive list of all embodiments. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other if there is no conflict.

[0032] The utility model will be further described below in conjunction with the accompanying drawings.

[0033] Figure 1 The structure of the pipe cutting device 100 according to the present invention is schematically shown;

[0034] Figure 2 is a side structural schematic diagram of a pipe cutting device 100 according to the utility model;

[0035] Figure 3 for Figure 1 Enlarged view of point A in the middle.

[0036] like Figures 1-2 As shown, the pipe cutting device 100 according to the utility model mainly includes a cutting disc 11 for cutting pipes (not shown in the drawings), and a clamping mechanism adapted to the cutting disc 11. The clamping mechanism includes a feeding table 21, and a first through slot 22 formed in the feeding table 21. Preferably, a screw rod 221 is accommodated in the first through slot 22.

[0037] According to the utility model, if Figures 1-2 As shown, the pipe cutting device 100 further includes a base 12 fixed to the lower end surface of the feeding platform 21. In this way, the pipe cutting device 100 can have good stability when performing cutting work.

[0038] In one embodiment of the present invention, Figures 1-2 As shown, the clamping mechanism also includes a clamping member sleeved on the screw rod 221, and a first motor 23 arranged at the first end of the feeding table 21. The clamping member can effectively clamp the pipe to ensure that the pipe has good stability during the cutting process; the first motor 23 is adapted to the screw rod 221, so as to drive the screw rod 221 to rotate to cause the clamping member to slide, and the content thereof is described below.

[0039] In the present invention, the first motor 23 can drive the screw rod 221 to rotate forward or reversely. Since the clamping member is threadedly connected to the screw rod 221, the clamping member can slide along the length direction of the first through slot 22 under the rotation of the screw rod 221 to drive the pipeline to be adjusted automatically, thereby facilitating the cutting work, and further improving the continuous cutting efficiency of the pipeline cutting device 100. Compared with the prior art, the present invention can automatically adjust the position of the pipeline for cutting work, thereby reducing the manual operation links, further reducing the labor cost and improving the work efficiency.

[0040] In one embodiment, Figures 1 to 3 As shown, the clamping member includes a body 31 configured as a T-shaped structure, and a clamping assembly disposed on the body 31. Preferably, the body 31 includes a sliding portion threadedly connected to the screw rod 221, and a fixed portion disposed above the sliding portion and used to place the clamping assembly.

[0041] In one embodiment, Figures 1 to 3 As shown, a second through groove 32 is formed at the upper end surface of the main body 31, and the clamping assembly includes a bidirectional threaded rod 41 arranged in the second through groove 32, a pair of spaced apart clamping rings 43 and a clamping ring 44 adapted to the bidirectional threaded rod 41, and an electric control box 42 arranged outside the main body 31 and adapted to the bidirectional threaded rod 41.

[0042] In the present invention, the bidirectional threaded rod 41 includes a forward rotating thread and a reverse rotating thread. Preferably, the clamping ring 43 is sleeved outside the forward rotating thread, and the clamping ring 44 is sleeved outside the reverse rotating thread. Therefore, when the bidirectional threaded rod 41 is driven to rotate by the electric control box 42, the clamping ring 43 and the clamping ring 44 will move toward or away from each other, thereby clamping or releasing the pipe to facilitate subsequent cutting work.

[0043] In other embodiments, the clamping ring 43 may also be sleeved outside the reverse rotating thread, and correspondingly, the clamping ring 44 may be sleeved outside the forward rotating thread.

[0044] In one embodiment, the clamping ring 43 and the clamping ring 44 are both constructed as semi-annular structures, and the inner wall surfaces of the clamping rings are both provided with anti-skid convex particles 45. Therefore, when the clamping rings 43 and 44 clamp the pipe, they can not only be more easily wrapped on the outer wall of the pipe through the semi-annular structure to increase the contact area between the clamping ring and the pipe, thereby increasing the holding force of the pipe cutting device 100 on the pipe; the anti-skid convex particles 45 can also increase the friction between the clamping ring and the pipe, thereby further improving the stability of the pipe during the cutting process.

[0045] Preferably, the cross section of the anti-skid convex particle 45 is a semicircular structure. In this way, the surface of the anti-skid convex particle 45 can have a certain smooth effect, thereby effectively avoiding the problem of damage to the pipeline caused by the anti-skid convex particle 45 during the clamping process.

[0046] In one embodiment, Figures 1-2 As shown, the clamping mechanism further includes a first fixing ring 24 disposed at the second end of the feeding platform 21, and a gantry 13 is further disposed on the base 12. Preferably, a second fixing ring 25 adapted to the first fixing ring 24 is disposed on the gantry 13.

[0047] In the present invention, the first fixing ring 24 and the second fixing ring 25 are spliced ​​to form an inner circle and outer square structure, so as to effectively fix the pipeline, and cooperate with the clamping ring 43 and the clamping ring 44 to ensure the stability of the pipeline during the cutting process.

[0048] In one embodiment, Figure 2As shown, a telescopic member is provided between the second fixing ring 25 and the gantry 13. Preferably, the telescopic member includes a second motor fixed on the inner wall of the gantry 13, and a telescopic rod 26 provided between the second motor and the second fixing ring 25. In the utility model, the telescopic rod 26 can be driven by the second motor to achieve longitudinal telescoping to further adjust the height of the second fixing ring 25, so that it can be more easily matched with the first fixing ring 24 to firmly press the pipeline, thereby avoiding damage caused by pipeline shaking during the cutting process.

[0049] Preferably, if Figure 1 As shown, a buffer pad 27 is provided on the inner wall of the first fixing ring 24 and the second fixing ring 25. In the present invention, the buffer pad 27 is made of rubber material, and when the first fixing ring 24 and the second fixing ring 25 contact the pipeline, the buffer pad 27 can play an effective buffering role, thereby avoiding damage to the outer wall of the pipeline.

[0050] According to the utility model, if Figures 1-2 As shown, the pipe cutting device 100 also includes a mounting frame 14 fixed on the base 12, a hydraulic cylinder 15 arranged between the mounting frame 14 and the cutting disc 11, and a hydraulic rod 16 adapted to the hydraulic cylinder 15. The mounting frame 14 is configured as an L-shaped structure, and includes a fixing plate 141 vertically arranged on the base 12, and a supporting plate 142 connected to the fixing plate and arranged parallel to the base 12. Preferably, the hydraulic cylinder 15 is fixed on the supporting plate 142, and can drive the hydraulic rod 16 to cause the cutting disc 11 to complete the lifting movement.

[0051] Preferably, if Figures 1-2 As shown, an extension hole 143 is provided on the fixing plate 141. In the present invention, according to the required length of the pipeline, the pipeline can pass outward through the extension hole 143. In this way, it can not only provide a certain support for the pipeline, but also avoid the trouble caused by the cutting operation when cutting a long pipeline.

[0052] The working principle of the utility model is introduced below:

[0053] First, the pipe is fixed to the body 31 by the clamping ring 43 and the clamping ring 44;

[0054] Then, the position of the body 31 in the first through slot 22 is adjusted by the first motor 23 to further change the position of the pipeline;

[0055] After that, after the cutting position is determined, the pipe is fixed for a second time by the first fixing ring 24 and the second fixing ring 25;

[0056] Finally, the hydraulic cylinder 15 and the hydraulic rod 16 push the cutting disc 11 downward to complete the work of cutting the pipe.

[0057] It is worth noting that if the pipe to be cut is long, the head of the pipe can be passed out through the extension hole 143.

[0058] Compared with the prior art, the advantages of the present invention are:

[0059] First, the utility model can drive the screw rod 221 to rotate forward or reversely by the first motor 23, so that the clamping member slides along the length direction of the first through slot 22, thereby realizing automatic adjustment of the position of the pipeline. It can be seen that the utility model does not need manual adjustment of the pipeline, thereby not only reducing labor costs but also effectively improving the efficiency of continuous cutting of the pipeline.

[0060] Secondly, the utility model can play a dual fixing and clamping role on the pipeline through the clamping ring 43 and the clamping ring 44 and the first fixing ring 24 and the second fixing ring 25, thereby not only ensuring the stability of the pipeline during the cutting process, but also effectively avoiding the damage caused by the shaking of the pipeline during the cutting process.

[0061] Thirdly, the utility model can smoothly adjust the position of the pipe according to the required length of the pipe by setting the extension hole 143 on the fixing plate 141. In other words, when the pipe to be cut is short, it can be fixed by the clamping ring 43 and the clamping ring 44 and the first fixing ring 24 and the second fixing ring 25; when the pipe to be cut is long, the head of the pipe is passed outward through the extension hole 143, which can solve the problem of cutting caused by the long pipe.
