Description

Technical Field

[0001] The utility model relates to a supporting device, specifically a temporary supporting device for pipe processing, mainly used for auxiliary support during pipe processing or for temporarily supporting and placing pipes, achieving the function of centralized placement and stacking of pipes, belonging to the auxiliary technical field of construction supplies. Background Technique

[0002] When generally carrying out pipe trench processing at the construction site, simple materials such as wooden beams and piers are usually used to assist workers for temporary support. This construction method not only wastes working hours, but also it is very difficult to ensure qualified quality in terms of processing accuracy.

[0003] Currently, although there are already devices in the prior art specifically for supporting and lifting pipes to assist in pipe processing, but currently these existing structures all have the problems of relatively complex structures and cumbersome operations during use. When welding and processing pipes of different diameters, manual adjustment of the device needs to be carried out multiple times to achieve.

[0004] After retrieval, the Chinese invention patent CN108057752A discloses a steel pipe flat bracket for a grooving machine. Although this kind of steel pipe flat bracket can adjust the height of the support according to the needs of the processing personnel, the adjustment of the existing structure needs to be done before the pipe is placed. Once the pipe is placed, it is very difficult to adjust the height of the entire support, and the adjustment is time-consuming and laborious. As the processing time prolongs, there will be a displacement in the adjusted height, which will affect the processing. In short, it is often very inconvenient. However, using this device as a temporary support during pipe trench processing can not only adapt to various pipe diameter processing scenarios, such as trench processing, grooving cutting, etc., but also can adjust to meet the processing requirements of different pipe diameters, and the height of the support can be freely adjusted to ensure that the pipe is in a horizontal position.

[0005] Therefore, the key to solving the above technical problems is to develop a temporary supporting device for pipe processing with a simple structure and convenient operation. Summary of the Invention

[0041] Wherein, a non-slip cushion is sleeved on the hand - holding part of the hand crank (52).

[0042] The working principle is as follows: Before using a temporary support device for pipe processing with the above - designed structure, the already - fabricated temporary support device needs to be manually carried directly by workers or transported to the designated pipe - processing position by corresponding handling equipment for use.

[0043] During use, first, the operator selects a reasonable number of multiple temporary support devices with the designed structure of the present utility model according to the number of pipes to be processed and the number of workers for standby. When installing and using, the operator only needs to place at least two temporary support devices with adjusted heights side by side and opposite to each other in the processing operation area and place them stably and reliably;

[0044] Then, the operator uses a hoisting device or manually by two operators to lift and place the pipe (7) above the support seat (1) of the side - by - side arranged support devices. Under the double - limit protection of the protective mounting seat (12) and the protective rod (6), the pipe (7) will not easily slide, so as to place the pipe (7) stably and reliably in the support seat (1) of the present utility model;

[0045] Finally, the operator can perform processing operations on the pipeline (7) above the support base (1). During the processing, the operator can rotate the crank (52) clockwise or counterclockwise to adjust the unilateral height or bilateral height of the pipeline (7). When raising the height of the pipeline (7), when the operator holds the grip part of the crank (52) and rotates it clockwise, the transmission screw rod (51) connected to the crank (52) will drive the first hinge rod (3) and the second hinge rod (4) to approach each other, thereby driving the support base (1) to move upward, and then achieving the purpose of raising the height of the pipeline (7). When lowering the height of the pipeline (7), the operator rotates the crank (52) counterclockwise, and the transmission screw rod (51) connected to the crank (52) will drive the first hinge rod (3) and the second hinge rod (4) to move away from each other, thereby driving the support base (1) to move downward, and then achieving the purpose of lowering the height of the pipeline (7). After adjusting to the appropriate pipeline processing position, the operator can stop rotating the crank (52), and then enter the corresponding subsequent pipeline processing process.

[0046] During the above entire operation and use process, if it is necessary to process the pipeline for a long time or prevent the entire support device from tilting and collapsing, the operator can pass the fastening screw or the jacking bolt through each reinforcement hole (211) on the base (2) for jacking and limiting fixation, so as to ensure the stability of the operator during the processing of the pipeline (7) and increase the safety during the pipeline processing.

[0047] The beneficial effects of the present utility model compared with the prior art are as follows:

[0048] 1. The structure of the present utility model is simple, highly practical, safe and reliable, convenient for handling, and can process pipelines of different lengths through free combination. It is flexible in use, simple in structure, novel and reasonable in design. According to the needs of pipeline processing, the height of the device can be manually adjusted to a suitable operating plane, thereby meeting the processing needs of the operator.

[0049] 2. The middle part of the protective plate of the protective mounting seat of the present utility model is provided with an arc-shaped or V-shaped recess, which can adapt to pipelines of various pipe diameters for processing operations.

[0050] 3. The protective mounting seat of the present utility model is also provided with a protective rod, which can better limit the pipeline to the central position of the support base, effectively prevent the pipeline from slipping, and achieve the protection of the safety of the operator.

[0051] 4. The two ends of the protective rod of the present utility model are also provided with protective pads, which can prevent the outer wall of the pipeline from being worn when the pipeline is placed and processed, and effectively protect the integrity of the supported pipeline.

[0052] 5. In addition to supporting the pipeline during pipeline processing, the utility model can also centrally stack and organize the pipelines during the process of pipeline placement and arrangement, preventing corrosion caused by directly placing the pipelines on the ground or pipeline rusting due to long-term contact with the ground, which affects the qualified quality of the pipelines. Furthermore, it can ensure the quality during the pipeline use process, meet the effect of centralized pipeline placement, and reach the requirements of civilized construction standards.

[0053] 6. The exterior of the utility model is coated with an anti-rust layer or a waterproof layer. Therefore, it can prevent rusting and extend the service life of the device. At the same time, a fluorescent layer is also sprayed on the exterior of the support device. Therefore, it can ensure the safety during underground construction or dark construction environments, play a warning role, improve visibility, and ensure construction safety.

[0105] Before using the temporary support device for pipeline processing of the above-mentioned design structure, the completed temporary support device needs to be directly transported manually or by corresponding transport equipment to a designated pipeline processing position for use.

[0106] In use, first, the operator selects a reasonable number of multiple temporary support devices with the design structure of the present invention for standby according to the number of pipes to be processed and the number of workers. During installation and use, the operator only needs to place at least two temporary support devices with adjusted heights side by side and relatively in the processing operation area and place them stably and reliably.

[0107] Then, the operator hoists the pipe 7 to above the support seat 1 of the support devices arranged side by side through a hoisting device or manually by two operators. Under the double limit protection of the protective mounting seat 12 and the protective rod 6, the pipe 7 will not easily slide, so as to place the pipe 7 stably and reliably in the support seat 1 of the present invention.

[0108] Finally, the operator can perform processing operations on the pipe 7 above the support seat 1.

When raising the height of the pipe 7, when the operator holds the handle part of the crank 52 and rotates it clockwise, the transmission screw 51 connected to the crank 52 will drive the first hinge rod 3 and the second hinge rod 4 to approach each other, thereby driving the support seat 1 to move upward, and then achieving the purpose of raising the height of the pipe 7. When lowering the height of the pipe 7, the operator rotates the crank 52 counterclockwise, and the transmission screw 51 connected to the crank 52 will drive the first hinge rod 3 and the second hinge rod 4 to move away from each other, thereby driving the support seat 1 to move downward, and then achieving the purpose of lowering the height of the pipe 7. After adjusting to a suitable pipe processing position, the operator can stop rotating the crank 52 and then enter the subsequent corresponding pipe processing process.

[0109] During the above entire operation and use process, if it is necessary to process the pipe for a long time or prevent the entire support device from tilting and collapsing, the operator can pass the fastening screws or the jacking bolts through the respective reinforcement holes 211 on the base 2 for jacking and limiting fixation, so as to ensure the stability of the operator when processing the pipe 7 and increase the safety during the pipe processing.
