Description

Technical Field

[0001] This utility model relates to the field of pipeline construction technology, specifically a pipeline insulation construction operation platform. Background Technology

[0002] Pipeline construction is a core component of urban infrastructure development, encompassing water supply and drainage, gas supply, heating, oil and gas transportation, and other sectors related to people's livelihoods and industry. Its core objective is to achieve the safe laying and long-term stable operation of pipeline networks through scientific planning and standardized operations.

[0003] Pipeline insulation construction is an important part of pipeline construction, aiming to reduce the transfer of heat from the system to the outside or the transfer of external heat into the system. It is generally carried out by wrapping an insulation layer around the outer surface of the pipeline.

[0004] When wrapping insulation layers around large-diameter pipes with high installation heights, the pipes are too thick. When wrapping the upper half of the pipe with a fixed-height work platform, it is relatively easy because the operator can stand and work. However, when wrapping the lower half of the pipe, the height difference requires the operator to squat or kneel, which can easily cause worker fatigue. Furthermore, due to the angle, the insulation material may not adhere tightly, affecting the insulation effect. Therefore, a pipe insulation construction work platform is proposed to address the above problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0034] Please see Figure 1-10 This utility model provides a technical solution:

[0035] A pipeline insulation construction platform includes a lifting platform 3, a work platform 4 fixedly connected to the upper end of the lifting platform 3, a base plate 41, a left limiting plate 42 fixedly connected to the upper end of the base plate 41, a right limiting plate 43 fixedly connected to the upper end of the base plate 41, an upper plate assembly 44 fixedly connected to one side of the left limiting plate 42, a guardrail 45 fixedly connected to the inner side of the left limiting plate 42, and the left limiting plate 42 includes a left upright plate 421, with a guardrail 45 on one side of the left upright plate 421. A horizontal plate 422 is fixedly connected, and a hollow tube 423 is fixedly connected to the inner side of the horizontal plate 422. A horizontal piston rod 424 is slidably connected to the inner side of the hollow tube 423. A rod head 425 is fixedly connected to one end of the horizontal piston rod 424. A vertical piston rod 426 is slidably connected to the inner side of the hollow tube 423. A handle 427 is fixedly connected to one end of the vertical piston rod 426. The right limiting plate 43 includes a right upright plate 431, and a support plate 43 is fixedly connected to one side of the right upright plate 431. 2. A locking post 433 is slidably connected to the inner side of the support plate 432. A connecting spring 434 is fixedly connected to one end of the locking post 433. A threaded hole 435 and a square hole 436 are opened on one side of the support plate 432. A bolt post 437 is spirally connected to the inner side of the threaded hole 435. A locking rod 438 is rotatably connected to the outer side of the bolt post 437. The upper plate assembly 44 includes a fixing plate 441. An ear plate 442 is opened at the upper end of the fixing plate 441. A lug 442 is fixedly connected to one side of the lug 441. A torsion spring 443 is fixedly connected to one side of the lug 442. A shaft 444 is rotatably connected to the inner side of the lug 442. A rotating plate 445 is fixedly connected to one end of the torsion spring 443. A through groove 446 is opened on the inner side of the rotating plate 445. A circular plate 447 is fixedly connected to the inner side of the through groove 446. A compression spring 448 is fixedly connected to one side of the circular plate 447. A sliding column 449 is fixedly connected to one end of the compression spring 448.

[0036] As a further implementation of this scheme, support columns 1 are set on both sides of the lifting platform 3. The two support columns 1 are symmetrically distributed. The lifting platform 3 is set below the pipe 2. Setting the lifting platform 3 below the pipe 2 facilitates various operations on the pipe 2. Since the support columns 1 on both sides are symmetrically distributed, they will not obstruct the operator's range of movement too much, making the operating space more open and improving work efficiency.

[0037] As a further implementation of this solution, two hollow tubes 423 are provided, symmetrically distributed. The horizontal piston rod 424 and the rod head 425 are on the same axis. The outer side of the horizontal piston rod 424 is in close contact with the inner side of the hollow tube 423. The outer diameter of the rod head 425 is the same as the inner diameter of the through groove 446. Two vertical piston rods 426 are provided, and the two vertical piston rods 426 are parallel to each other. Part of the vertical piston rod 426 is set in the hollow tube 423. The structure of the vertical piston rod 426 is the same as that of the horizontal piston rod 424. The arrangement of the two hollow tubes 423 can better play a guiding role, ensuring that the horizontal piston rod 424 and the vertical piston rod 426 move along a predetermined trajectory, thereby better realizing the operating effect of the device. The coaxial design of the horizontal piston rod 424 and the rod head 425 can ensure that the horizontal piston rod 424 maintains linear motion during the movement, reducing friction and wear with other components, and improving the smoothness and reliability of the movement.

[0038] As a further implementation of this solution, the right vertical plate 431 and the left vertical plate 421 are parallel to each other, the upper end face of the support plate 432 and the upper end face of the horizontal plate 422 are on the same horizontal plane, a part of the locking post 433 is set in the through groove 446, one end of the locking post 433 is attached to one side of the circular plate 447, and one end of the connecting spring 434 is fixedly connected to the support plate 432. The design that the upper end face of the support plate 432 and the upper end face of the horizontal plate 422 are on the same horizontal plane can ensure that the two components are at the same height during installation and use, providing a flat and stable support platform to prevent instability caused by height difference. The setting of the locking post 433 can better restrict the rotation of the rotating plate 445.

[0039] As a further implementation of this solution, two square holes 436 are provided and symmetrically distributed on one side of the support plate 432. The angle between the locking rod 438 and the support plate 432 is 90°. The outer side of the locking rod 438 is in close contact with the inner side of the square hole 436. The setting of the outer side of the locking rod 438 in close contact with the inner side of the square hole 436 makes the locking rod 438 more stable during movement, so as to accurately reach the preset position and play a role in restricting the rotation of the rotating plate 445.

[0040] As a further implementation of this solution, a cavity is provided on the inner side of the fixing plate 441, and several holes are evenly distributed in a rectangular array at the upper end of the fixing plate 441. Two hollow tubes 423 are provided and are symmetrically distributed. The circular plate 447, the compression spring 448 and the sliding column 449 are on the same axis. The sliding column 449 and the locking column 433 are magnetically attracted to each other. The holes at the upper end of the fixing plate 441 can change the friction of the upper surface of the fixing plate 441, thereby achieving an anti-slip effect. At the same time, debris and other garbage falling on the upper end of the fixing plate 441 can enter the cavity inside the fixing plate 441 through the holes, ensuring the cleanliness of the upper surface of the fixing plate 441 and preventing the operator from slipping after stepping on it. The coaxial design of the circular plate 447, the compression spring 448 and the sliding column 449 allows the sliding column 449 to better bear the force and slide in the through groove 446.

[0041] Workflow: When using the device, move the lifting platform 3 to the middle of the two support columns 1 and below the pipe 2. Then adjust the height of the lifting platform 3 so that the worktable 4 on the lifting platform 3 is at a suitable angle. At this time, you can stand on the upper plate assembly 44 to wrap the insulation layer around the pipe 2. The guardrail 45 provides safety protection. When wrapping the pipe 2, you can first wrap the upper half of the pipe 2. After the upper half of the pipe 2 is wrapped, you can hold the handle 427 and lift it upward. When the handle 427 moves upward, the vertical piston rod 426 will be in the hollow... The inner side of the tube 423 slides, creating a negative pressure inside the hollow tube 423. At this time, the horizontal piston rod 424, influenced by the negative pressure inside the hollow tube 423, will slide deeper into the hollow tube 423. After the horizontal piston rod 424 has slid a certain distance, the rod head 425 will exit from the through groove 446 and be completely inside the horizontal plate 422. At this time, the rod head 425 no longer applies pressure to the sliding column 449. Under the elastic force generated by the compression spring 448, the sliding column 449 will move away from the circular plate 447. At this time, the positions of the sliding column 449 and the locking column 433 change. The magnetic attraction between the locking posts 433 is less than the pulling force of the connecting spring 434 on the locking posts 433. Under the action of the pulling force of the connecting spring 434, the locking posts 433 will exit from the through slot 446 and fully enter the support plate 432. At this time, stepping down on the rotating plate 445 will cause the rotating plate 445 to rotate on one side of the fixed plate 441. The ear plate 442 and the shaft 444 limit the rotation of the rotating plate 445. At the same time, the torsion spring 443 deforms. After the rotating plate 445 has rotated a certain distance, the worker can go down to the platform from the distance between the two fixed plates 441. On the surface of plate 41, by rotating bolt column 437, the bolt column 437 drives the clamping rod 438 to extend out of square hole 436 through the threaded hole 435, thereby limiting the rotating plate 445. At this time, the worker can better wrap the lower half of the pipe 2, avoiding the need to bend over due to an unsuitable standing position, which would make it difficult to wrap the insulation layer, resulting in a loose fit and affecting the effect. After the wrapping is completed, simply rotate bolt column 437 again and push clamping rod 438 back to its position. At this time, the rotating plate 445 will quickly return to its original position under the force generated by the recovery deformation of torsion spring 443.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
