Description

Technical Field

[0001] This utility model relates to an auxiliary device for steel pipe threading. Background Technology

[0002] In modern building interior design, small-diameter steel pipes in fire suppression systems are connected using threaded connections. After the steel pipes are transported to the construction site, they need to be threaded centrally before installation. In actual construction, during the threading process, one end of the steel pipe is placed in the threading machine, while the other end often requires manual assistance to hold, or is placed on a wooden frame. The former has low production efficiency, and it is difficult for one person to operate when the steel pipe is long. In addition, the steel pipe is prone to tilting, resulting in failure to thread or inaccurate threading. Therefore, designing an auxiliary device with accurate positioning and high stability is the research direction of this utility model. Utility Model Content

[0025] Reference Figure 1-5 As shown, an auxiliary device for threading steel pipes includes...

[0026] A central rod 1; a first elastic element 10 is sleeved on the outer wall of the central rod 1.

[0027] A support structure 2 is provided at one end of the central rod 1. The support structure 2 includes a support 20, on which a placement assembly for placing steel pipes is stacked sequentially. The placement assembly includes a first support 21, a second support 22, and a third support 23. Assembly rods 230 are provided at both ends of the second support 22 and the third support 23, and positioning bolts 24 are provided at both ends of the first support 21. Adjustment rulers 27 are symmetrically arranged at the front and rear ends of the support 20. Support ends 28 are provided on the adjustment rulers 27, and insertion holes 29 are arranged at equal intervals on the adjustment rulers 27. A positioning block 312 is provided at the bottom of the support 20, and a pin 313 is movably mounted on the positioning block 312. The pin 313 is inserted into the insertion holes 29 on the adjustment ruler 27 to position the support 20.

[0028] In this embodiment, the support structure 2 works in conjunction with the central rod 1 to form a stable and adjustable support system for placing and fixing steel pipes. The support structure 2 includes a support 20 on which multiple placement components are stacked: a first support 21, a second support 22, and a third support 23 (three support assemblies of different specifications to place steel pipes of different sizes). These placement components together form a multi-layered support platform. Each component is fixed in place by assembly rods 230 or positioning bolts 24 at both ends to ensure the stability of the entire structure and the correct placement of the steel pipes. The design of the support 20 is particularly critical. The adjusting scales 27 symmetrically arranged at its front and rear ends are equipped with support ends 28. These support ends 28 provide additional support force and enhance the stability of the structure. The insertion holes 29 on the adjusting scales 27 are connected to the positioning blocks 31 at the bottom of the support 20. The pin 313 on support 20 allows for precise positioning, adapting to various installation needs and environmental conditions. The movable pin 313 allows support 20 to move within a certain range and be fixed via the insertion hole 29, enabling fine-tuning to ensure the accuracy and reliability of the support structure. Through the cooperation and coordinated operation of these components, the entire support structure 2 achieves stable support and precise positioning of the steel pipe. The use of the adjusting ruler 27 and pin 313 provides structural flexibility and adaptability, enabling the support structure to adapt to different installation scenarios, maintaining the stability of the steel pipe in both straight and curved arrangements. Furthermore, the use of positioning bolts 24 and assembly rods 230 ensures a tight connection between the components, further improving the stability and load-bearing capacity of the entire support system. In summary, this design not only improves the installation efficiency of the support structure but also ensures the safety and stability of the steel pipe within the support structure, making it suitable for various building and engineering applications.

[0029] It should be noted that the central rod 1 is a telescopic rod, and the central rod is divided into a first support rod and a second support rod. The first support rod is connected to the support 20, and the second support rod has a cavity inside, in which an elastic element is installed. The first rod is connected to the elastic element, so that the support 20 has a buffering and pressure-resistant effect, avoiding support fatigue and damage to the support 20 (the above structure is not shown in this case).

[0030] Furthermore, a mounting groove is formed on the support 20, and a shaft 25 is provided inside the mounting groove, with a sliding wheel 26 movably mounted on the shaft 25. In actual use, since steel pipes have different specifications, even with the placement component provided in this embodiment to place steel pipes of different specifications, there will inevitably be thinner steel pipes. Therefore, a space is reserved between the placement component and the support 20 for installing thinner steel pipes. The steel pipe can pass through this space and slide through the sliding wheel 26 on the shaft 25, thereby enabling threading of more types of steel pipes.

[0031] An auxiliary positioning structure 3 is sleeved on the central rod 1 and used to support the steel pipe; the auxiliary positioning structure 3 includes a first positioning element 30 and a second positioning element 31; wherein, a first rod 33 and a third rod 310 are movably arranged at both ends of the first positioning element 30 and the second positioning element 31, a second rod 36 is arranged between the first rod 33 and the third rod 310, a support rod 39 is arranged at one end of the first rod 33, and a movable support structure is arranged at one end of the support rod 39; a first movable element 34 is arranged at both ends of the first positioning element 30 and the second positioning element 31, the first movable element 34 is connected to the first rod 33 and the third rod 310, a second movable element 35 is also arranged on the first rod 33 and connected to the second rod 36, and a third movable element 38 is arranged at the other end of the first rod 33 and connected to the support rod 39;

[0032] In this design, a clearance groove 37 is formed at the end of the second rod 36 that is connected to the first movable member 34.

[0033] The movable support structure includes a fourth movable member 390 disposed at one end of the support rod 39, and a first support block 391 and a second support block 392 hinged to the fourth movable member 390.

[0034] A movable groove 3100 is formed at the connection between the third rod 310 and the support rod 39, a fifth movable member 3111 is connected to the movable groove 3100, and a second elastic member 3112 is disposed inside the movable groove 3100.

[0035] The first positioning member 30 and the second positioning member 31 each have a mounting port 32 at their center for connection with the center rod 1. The top surface of the second positioning member 31 has a connection port 311 on both sides of the mounting port 32 for insertion into the adjusting ruler 27.

[0036] When supporting the steel pipe, the auxiliary positioning structure 3 works in conjunction with the central rod 1 to support and stabilize the steel pipe. The auxiliary positioning structure 3 includes a first positioning element 30 and a second positioning element 31, which are interconnected by movable rods at both ends—a first rod 33, a second rod 36, a third rod 310, and a support rod 39—to form an adjustable support frame. These members are connected by multiple movable parts (first movable part 34, second movable part 35, and third movable part 38), making the entire structure flexible and expandable. When the steel pipe needs support, it is placed on the placement assembly, and the central rod 1 bears the force and supports the placement assembly. At this time, the first rod 33, the third rod 310, and the support rod 39 expand outward under the action of force. Through the synergistic action of the first movable part 34, the second movable part 35, and the third movable part 38, the contact area between the steel pipe and the placement assembly is increased, thereby improving the stability of the steel pipe. The relief groove 37 formed at the end of the second rod 36 connected to the first movable part 34 allows the second rod 36 to have a certain amount of movement space when under force, further enhancing the adaptability and stability of the structure. The dynamic support structure, including a fourth movable component 390, a first support block 391, and a second support block 392, is connected by a hinge, providing additional support force to ensure the steel pipe's stable position on the placement assembly. The movable groove 3100 formed at the connection between the third rod 310 and the support rod 39 cooperates with the fifth movable component 3111 and the second elastic component 3112, providing elastic support and buffering for the structure, effectively protecting the steel pipe from external impacts. The mounting port 32 formed at the center of the first positioning component 30 and the second positioning component 31 is used to connect with the central rod 1, ensuring the stability of the entire auxiliary positioning structure 3. The connection port 311 on the top surface of the second positioning component 31 is inserted into the adjusting ruler 27, further enhancing the structure's adjustability and adaptability. In summary, this solution achieves effective support and stability for the steel pipe through the coordinated work of the auxiliary positioning structure 3 and the central rod 1. The precise design and mutual cooperation of the various components in the structure not only improve the stability of the steel pipe but also enhance the flexibility and adaptability of the entire support system, making it suitable for various installation environments and application scenarios.

[0037] Furthermore, in practical use, the solution of this embodiment can play an effective supporting role. Moreover, since the steel pipe needs to be fixed during the processing, and there are already good technologies for fixing structures in the prior art, this solution does not set up an additional fixing structure. The fixing structure can be set up according to actual needs.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
