Description

Technical Field

[0001] This utility model relates to the field of pipeline engineering technology, and in particular to a pre-treatment and cutting equipment for large petrochemical pipe fittings. Background Technology

[0002] With the development of modern technology, pipeline transportation is used in more and more fields. In the field of chemical engineering, pipelines are often used for product production and transportation. Large pipelines need to be cut during the laying and maintenance process to meet the actual application needs. At present, when cutting larger pipelines, it is generally necessary to use a support device to support the pipeline, and then use a cutting device to cut the pipeline.

[0003] Currently, pipe cutting commonly employs two methods: manual handheld cutting machines and large mechanical cutting machines. When using a manual handheld cutting machine, the worker first cuts a section of the pipe, then rotates the pipe to allow the cutting blade to cut the remaining sections. This method is inaccurate, unstable, extremely physically demanding, poses significant safety hazards, and is inconvenient for workers. When using a large mechanical cutting machine, a support device is typically needed to support the pipe before the cutting device cuts it. Furthermore, a gantry crane is used for transportation, which requires considerable space and places high demands on factory space. The operation of the gantry crane is also cumbersome and time-consuming. Therefore, it is necessary to provide a large-scale petrochemical pipe pretreatment and cutting equipment to solve the aforementioned technical problems. Utility Model Content

[0013] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0014] Please refer to the following: Figure 1-6A large petrochemical pipe pretreatment cutting device includes a cutting device 3. The cutting device 3 includes a cutting bracket 301. A cutting ring rail 302 is fixedly installed on the upper part of the cutting bracket 301. A ring gear 304 is fixedly installed inside the cutting ring rail 302. The ring gear 304 meshes with a second gear 305. The second gear 305 is fixedly connected to the output end of a third motor 307. The third motor 307 is fixedly installed on a cutting support frame 306. The cutting support frame 306 is fixedly connected to a second telescopic rod 309 by bolts. A fourth motor 308 is fixedly installed at one end of the second telescopic rod 309. The output end of the fourth motor 308 is connected to a cutting tool 310. Support devices 1 are symmetrically arranged on both sides of the cutting device 3 with respect to the central plane. A clamping device 2 is fixedly arranged on the side of the support device 1 closest to the cutting device 3.

[0015] The cutting ring rail 302 has a fixed ring rail groove 303 inside, which is slidably connected to the cutting support frame 306. A third motor 307 is fixedly installed on the lower sliding plate of the cutting support frame 306. A support plate is fixedly installed on the upper side of the sliding plate of the cutting support frame 306. A telescopic groove is provided on the upper part of the support plate. The telescopic groove has multiple threaded holes that are bolted to a second telescopic rod 309. A fourth motor 308 is fixedly installed on the upper part of the second telescopic rod. A cutter 310 is fixedly installed on the output end of the fourth motor 308. The second telescopic rod 309 allows the device to extend and retract according to the diameter of the pipe during cutting, thus expanding its application range.

[0016] The support device 1 includes a base plate 101, with support legs 102 fixedly installed at the four corners of the lower part of the base plate 101. Multiple rollers 14 are provided on the inner side of the base plate 101, and a first motor 103 is fixedly installed on one side of the middle part of the base plate 101. The output end of the first motor 103 is rotatably connected to a belt, and the belt is rotatably connected to the rollers 14. This makes it easier to transport the pipes when they are being cut, improves the applicability of the equipment, and reduces complex operations.

[0017] The clamping device 2 includes a clamping support frame 201. Two support beams are arranged on the upper part of the clamping support frame 201. A support platform is provided on the upper part of the support beam near the cutting device 3. A hydraulic cylinder 203 is fixedly installed on the upper part of the support platform. A hydraulic pump 202 is connected to the side of the hydraulic cylinder 203 via a hydraulic connecting pipe. The hydraulic pump 202 is fixed to the support platform. A hydraulic rod 204 is connected to the output end of the hydraulic cylinder 203. An upper clamping plate 205 is connected to the lower side of the hydraulic rod 204. Sliding slots 211 are fixedly installed on the left and right sides above the other support beam. The sliding slots 211 slidably connect to the sliding plate. The sliding rod 208 has a rack fixedly installed on the inner side of its upper part. A second motor 206 is fixedly installed on the upper part of the support beam. A first gear 207 is fixedly installed on the output end of the second motor 206. The first gear 207 is fixedly installed on the rack on the sliding rod 208 through gear meshing. The lower part of the sliding rod is connected to a first telescopic rod 209 by bolts. A side clamping plate 210 is fixedly installed on the lower part of the first telescopic rod 209 by bolts. Thus, when the pipe moves to the cutting position, the second motor 206 and the hydraulic cylinder 203 can drive the side clamping plate 210 and the upper clamping plate 205 to clamp the pipe.

[0018] The sliding rod 208 has a telescopic groove at its lower part, and multiple threaded holes are provided on the outside of the telescopic groove. The threaded holes are connected to the first telescopic rod 209 by bolts, which makes the position of the pipe more accurately fixed when the pipe is pre-processed and cut, and makes it easier to replace, reducing the cost of use and the difficulty of replacement operation.

[0019] The upper clamping plate 205 is connected to the hydraulic rod 204 by multiple bolts. The upper clamping plate 205 is designed in an arc shape, which makes the position of the pipe more accurately fixed when the pipe is pre-processed and cut, and makes it easier to replace, reducing the cost of use and the difficulty of replacement operation.

[0020] Working principle: When the pipe needs to be cut, firstly, the pipe is transported to the bottom plate 101 and the first motor 103 is turned on. The first motor 103 drives the roller 104 to rotate, transporting the pipe towards the cutting device 3. When the pipe is transported to the cutting position, the first motor 103 is stopped. Then, the first telescopic rod 209 is adjusted to a suitable position and fixed to the sliding rod 208 with bolts. After adjustment, the second motor 206 is turned on, causing the side clamping plate 210 to clamp the pipe. Then, the hydraulic pump 202 is turned on, causing the upper clamping plate 205 to extend and retract downward to clamp the pipe, thus fixing the pipe. After completion, adjust the second telescopic rod 309 so that the cutter 310 reaches the appropriate working position. Then, turn on the third motor 307 and the fourth motor 308 so that the cutter 310 can perform circumferential cutting on the pipe. After the cutting is completed, turn off the third motor 407 and the fourth motor 308, then turn off the second motor 206, and at the same time turn on the hydraulic pump 202 so that the upper clamping plate 205 can extend and retract upward to release the clamp on the pipe. After the clamp is released, turn on the first motors 103 on both sides so that the cut pipe moves to both sides to the transfer device and leaves the pre-processing cutting equipment.
