Description

Technical Field

[0001] This utility model belongs to the field of pipe processing technology, and in particular relates to a rotating and sliding tripod for pipe processing. Background Technology

[0002] In the field of pipe processing, operations such as cutting, welding, and grinding are often required, which necessitates stable and reliable pipe support equipment. The rotating and sliding tripod for pipe processing is a key device for supporting pipe processing; its stability directly affects the quality of pipe processing, operational safety, and work efficiency.

[0003] When processing pipelines, there is a need for outdoor processing, such as in the laying of long-distance oil and gas pipelines, where the construction environment is complex and pipelines need to be processed on-site in the field. Tripods are easy to transport and quickly set up in different terrains, enabling on-site processing of pipelines without the support of fixed processing facilities. However, it is often difficult to ensure the flatness of the ground in outdoor environments. Therefore, existing technologies often choose adjustable screw support feet and nut assemblies to support the tripod on all four sides.

[0004] However, the above method has a significant problem: while adjusting the extension length of the screw support legs ensures stable placement, when one or more screw support legs need to extend considerably, the longer-extended legs bear greater pressure than the shorter-extended legs, creating weak support points and uneven stress distribution, leading to a shift in the tripod's overall center of gravity. During pipe processing, external forces such as the torque generated by pipe rotation and vibrations during cutting can easily cause the tripod to slip, resulting in instability. Therefore, we propose a pipe processing rotating sliding tripod, which extends two wider legs by lowering the displacement, obtaining a larger contact area and thus improving placement stability.

[0005] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content

[0006] To address the aforementioned issues, the purpose of this invention is to provide a rotating sliding tripod for pipe processing. By lowering the tripod, the two widened legs extend, resulting in a larger contact area and thus improving placement stability.

[0007] To achieve the above objectives, this utility model proposes a rotating and sliding tripod for pipe processing, including a tripod base. An adjustable support leg is threadedly connected inside the tripod base. An extension mechanism for sliding widening is provided inside the adjustable support leg. The extension mechanism includes two rectangular widened base plates, a lifting support, and two connecting rods. Both rectangular widened base plates are slidably connected inside the adjustable support leg. The lifting support is slidably connected inside the tripod base. The two connecting rods are rotatably connected to the lifting support and the outer surfaces of the two rectangular widened base plates, respectively. An internally threaded cylinder is threadedly connected to the outer surface of the adjustable support leg, and the lifting support is located on the outer surface of the internally threaded cylinder.

[0008] Specifically, a bearing is fitted onto the outer surface of the internally threaded cylinder, and the bearing is fitted onto the inner surface of the lifting support.

[0009] Specifically, the upper end of the tripod base is provided with a rotating sliding mechanism for pipe support. The rotating sliding mechanism includes an external threaded lifting rod, a pipe placement platform, and two sets of gold balls.

[0010] Specifically, the external threaded lifting rod is threadedly connected to the upper end of the tripod base.

[0011] Specifically, the pipe placement platform is rotatably connected to the outer surface of the externally threaded lifting rod.

[0012] Specifically, both sets of alloy balls are rotatably connected inside the pipe placement platform.

[0013] The pipe processing rotary sliding tripod proposed in this utility model can bring the following beneficial effects:

[0014] When the ground is uneven during outdoor placement, the extension length can be controlled by screwing on the four adjustable support feet inside the tripod base. When one or more adjustable support feet extend too far, use a hex wrench to screw on the internal threaded cylinder. The internal threaded cylinder will cause the lifting support to move independently relative to the rectangular widened base plate. The displacement of the lifting support and connecting rod will push the rectangular widened base plate to extend, increasing the contact area. Rubber anti-slip pads are installed on the surface of the rectangular widened base plate and the adjustable support feet. The rubber anti-slip pads will increase friction, ensure the stability of the base, and significantly increase friction to resist external forces generated during pipe processing, as well as wind forces that may occur outdoors. This further prevents the tripod from sliding, shifting, or tipping over, comprehensively improving the stability of the placement from static placement to dynamic processing.

[0026] like Figures 1-4 As shown in the figure, the embodiment of this utility model proposes a rotating and sliding tripod for pipe processing, which includes a tripod base 1. The tripod base 1 serves as the base of the tripod as a whole, and together with the external threaded lifting rod 8 and the pipe placement platform 9 at its upper end, it forms the tripod as a whole, which is used to place pipes that need to be processed in an outdoor environment.

[0027] The tripod base 1 has an internal threaded connection to adjustable support feet 2. There are four adjustable support feet 2 in total (see the instruction manual). Figure 1 , 2 As can be seen, the adjustable support feet 2 are key components for the flat placement of the tripod base 1. By turning the four adjustable support feet 2 individually, the number of turns can be controlled to obtain different extension lengths. The four adjustable support feet 2 with different extension lengths provide support for the tripod base 1, thereby ensuring that the tripod base 1 can stably contact the ground in outdoor processing environments and ensuring the stable placement of the pipe. After the adjustment is completed, the stability of its placement needs to be ensured by turning the nuts and washers.

[0028] The adjustable support foot 2 contains two rectangular widened base plates 3, a lifting support 4, and two connecting rods 5. The two rectangular widened base plates 3 are slidably connected inside the adjustable support foot 2. These two rectangular widened base plates 3, sliding within the adjustable support foot 2, are used to achieve lateral widening, thereby increasing the contact area with the ground. Dovetail-shaped sliders are installed on both sides of the outer surface of the rectangular widened base plates 3, which slide within the adjustable support foot 2. Rubber anti-slip pads are glued to the lower ends of the two rectangular widened base plates 3 and the adjustable support foot 2 to further increase the contact area with the ground. Due to the friction of the surface, the lifting support 4 is slidably connected inside the tripod base 1. Four T-shaped rods are installed on the upper end of the lifting support 4. The T-shaped rods limit the sliding inside the tripod base 1, and the protrusions at the upper ends of the four T-shaped rods limit the maximum sliding length of the lifting support 4. Two connecting rods 5 are rotatably connected to the outer surfaces of the lifting support 4 and the two rectangular widened base plates 3 respectively. When the lifting support 4 slides downward, it will push the rectangular widened base plates 3 outward through the connecting rods 5 to slide outward. When the lifting support 4 slides upward, the opposite is true, pushing the rectangular widened base plates 3 inward to slide and retract.

[0029] The adjustable support foot 2 has an internally threaded cylinder 6 threadedly connected to its outer surface. The internally threaded cylinder 6 is rotatably connected to the bearing 7. When the adjustable support foot 2 is twisted or extended, it pulls the lifting support 4 to move through the internally threaded cylinder 6. At this time, the lifting support 4 and the two rectangular widened base plates 3 move synchronously without pushing them to move. When the adjustable support foot 2 extends downwards, the operator uses a hex wrench to screw the internally threaded cylinder 6, which drives the lifting support 4. At this time, the lifting support 4 moves independently relative to the rectangular widened base plate 3. The rectangular widened base plate 3 is pushed to retract or extend by the displacement of the lifting support 4 and the connecting rod 5. The bearing 7 is sleeved on the outer surface of the internally threaded cylinder 6 and sleeved on the inner surface of the lifting support 4. The internally threaded cylinder 6 is rotatably connected to the lifting support 4 through the sleeved bearing 7 on its outer surface.

[0030] The upper end of the tripod base 1 is equipped with an external threaded lifting rod 8, a pipe placement platform 9, and two sets of gold ball bearings 11. The external threaded lifting rod 8 is threadedly connected to the upper end of the tripod base 1. The threaded connection of the external threaded lifting rod 8 can control the extension height, thereby adjusting the placement height of the pipe being processed. Inside the tripod base 1, a handle limiting rod is threadedly connected. By turning the handle limiting rod, it contacts and presses against the external threaded lifting rod 8, thus preventing the external threaded lifting rod 8 from loosening or shifting during pipe processing. The smooth surface of the external threaded lifting rod 8 provides rotational support for the upper pipe placement platform 9. The pipe placement platform 9 is rotatably connected to the outer surface of the external threaded lifting rod 8. The upper surface of the pipe placement platform 9 is in a triangular shape, and a nearly V-shaped placement groove is formed inside, so that the pipe being processed has at least two points of contact area with the upper surface of the pipe placement platform 9. Both sets of gold balls 11 are rotatably connected inside the pipe placement platform 9. The alloy balls 11 rotate inside the pipe placement platform 9, and their spherical shape can rotate freely 360 degrees. When the pipe is placed on the upper end of the pipe placement platform 9, it will contact the surface of the two sets of gold balls 11. At this time, the alloy balls 11 provide support for the rotation and sliding adjustment of the pipe.

[0031] Working principle: When placed outdoors, the extension length is controlled by turning the four adjustable support feet 2 inside the tripod base 1. When the ground is uneven and the extension is too long, the internal thread cylinder 6 outside the adjustable support feet 2 is turned with a hex wrench, which drives the lifting support 4 to move independently relative to the rectangular widened base plate 3. The displacement of the lifting support 4 and the connecting rod 5 pushes the rectangular widened base plate 3 to extend and increase the contact area. The rubber anti-slip pads increase the friction and ensure the stability of the base. The extension height is controlled by turning the external thread lifting rod 8 at the upper end of the tripod base 1 to adjust the pipe placement height. The pipe is placed on the pipe placement platform 9, which has a triangular-like upper end and a near-V-shaped internal placement groove to ensure that the pipe has at least two points of contact to ensure stability. The two sets of gold ball bearings 11 can rotate freely 360 degrees, providing support for the rotation and sliding adjustment during pipe processing.
