Description

Technical Field

[0001] This utility model relates to the technical field of preheating devices, and more specifically, to a preheating device for gas pipeline processing. Background Technology

[0002] Gas pipelines are pressurized pipelines used to transport natural gas, manufactured gas, liquefied petroleum gas, and other gases. They are important infrastructure for urban energy supply and industrial production. They are usually buried underground and are made of materials such as steel pipes and PE pipes. They are pressurized by pressurization stations and transported from gas source plants and gate stations to urban pressure regulating stations, and then distributed to industrial users, residential users, and commercial users. It is one of the main methods of modern energy transmission. When processing gas pipelines, preheating devices are needed to preheat the processing area.

[0003] For example, Chinese patent disclosure: A preheating device for a pipe opening, application number: CN201921974735.9, includes: a circular back plate, a central heating unit and circumferential heating units distributed along the circumference of the circular back plate, the central heating unit and the circumferential heating units are both connected to the circular back plate through adjustable guide rails, and an annular heating cylinder is provided on the outer circumferential surface of the circular back plate, the annular heating cylinder is connected to a fixed bracket.

[0004] However, the existing gas pipeline preheating devices in the above-mentioned technical solutions adopt an integral structure with fixed heating units. Their design focuses on heating efficiency and temperature control accuracy, and does not adequately consider the space occupation of the device when it is not in operation. This makes the large overall size of these devices cause significant inconvenience for transportation and storage after the completion of on-site work or when they need to be moved to different work sites (gas pipelines are mostly installed outdoors). Not only may they require large transportation vehicles, but they also occupy valuable storage space, which is extremely inconvenient for work teams that need to frequently move construction sites. Utility Model Content

[0005] The main objective of this invention is to provide a preheating device for gas pipeline processing, which can effectively solve the problem that existing gas pipeline preheating devices in the background technology adopt an integral structure with fixed heating units. Their design focuses on heating efficiency and temperature control accuracy, but does not adequately consider the space occupation of the device when it is not in operation. This makes the large overall size of these devices, after completing on-site work or when they need to be moved to different work sites (gas pipelines are mostly installed outdoors), cause significant inconvenience to transportation and storage. It may require large transportation vehicles and occupy valuable storage space, which is extremely inconvenient for work teams that need to frequently move work sites.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a preheating device for gas pipeline processing, comprising a base, a protective shell fixedly mounted on the base, a groove provided on the protective shell, a chassis slidably mounted in the groove, a plurality of first sliding grooves provided in the center of the chassis and a plurality of second sliding grooves distributed along the circumference of the chassis, a sliding plate slidably mounted in each of the first and second sliding grooves, two support plates fixedly mounted on the outer wall surface of one side of the sliding plate, an adjustment component provided on the support plate, a heating unit provided on the adjustment component, a plurality of threaded holes provided on the inner wall of one side of each of the first and second sliding grooves, and screws threadedly mounted on the sliding plate.

[0007] Preferably, the heating unit is located between two support plates.

[0008] Preferably, the adjustment assembly has a first rotating column rotatably mounted on the support plate, a worm gear is mounted on the first rotating column, and a worm is engaged with one side of the worm gear.

[0009] Preferably, the worm gear is provided with a second rotating column, and a knob is fixedly provided on one end of the second rotating column.

[0010] Preferably, the first rotating column is fixedly connected to the heating unit.

[0011] Preferably, the worm gear is rotatably connected to the support plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) When the device needs to be moved, the chassis is first pushed so that the part of the chassis outside the groove enters the groove. Then, the second rotating column is rotated by the knob. The second rotating column drives the worm to rotate, the worm drives the worm wheel to rotate, and the worm wheel drives the heating unit to rotate through the first rotating column. The heating unit rotates 90 degrees around the first rotating column, so that the part of the heating unit outside the groove is taken into the groove, reducing the overall space occupied by the device and making it convenient to transport the device.

[0022] When the heating unit 10 needs to be stored, the second rotating column 904 is rotated by the knob 905. The second rotating column 904 drives the worm gear 903 to rotate, the worm gear 903 drives the worm wheel 902 to rotate, and the worm wheel 902 drives the heating unit 10 to rotate through the first rotating column 901, so that the heating unit 10 rotates 90 degrees around the first rotating column 901, thereby storing the heating unit 10.

[0023] The working principle of a preheating device for gas pipeline processing:

[0024] In use, first turn screw 12 to move a portion of it out of the threaded hole 11, releasing the fixation of the slide plate 7. Then adjust the position of the slide plate 7 so that the heating unit 10 is at a suitable distance from the inner and outer walls of the gas pipeline to be heated. Next, turn screw 12 to fix the position of the slide plate 7 through screw 12 and threaded hole 11. Then the gas pipeline can be heated by the heating unit 10. When the device needs to be moved, first push the chassis 4 so that the part of the chassis 4 outside the groove 3 enters the groove 3. Then, turn the knob 905 to rotate the second rotating column 904. The second rotating column 904 drives the worm gear 903 to rotate, and the worm gear 903 drives the worm wheel 902 to rotate. The worm wheel 902 drives the heating unit 10 to rotate through the first rotating column 901, so that the heating unit 10 rotates 90 degrees around the first rotating column 901, thereby taking the part of the heating unit 10 outside the groove 3 into the groove 3, reducing the overall space occupied by the device and facilitating the transportation of the device.
