[0029] The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0030] This invention provides an angle-adjustable pipeline clamp, including a clamping platform 1, a support, and a clamping assembly. The following is a detailed description of each part.

[0031] like Figure 1 , Figure 2 As shown, in an embodiment of the present invention, an angle-adjustable pipeline clamp includes:

[0032] Clamping table 1, for detachable connection to the worktable;

[0033] Support, set on the workbench;

[0034] The clamping assembly, rotatably connected to the support, is used to clamp the pipeline to be processed.

[0035] The workbench is a dedicated operating platform for pipeline processing and can adopt any of the existing structural forms. The clamping table 1 is the mounting base for the support and clamping components. The three are connected to form an integral structure of the pipeline clamp, realizing integrated installation and disassembly. By designing the workbench and clamping table 1 as separate and detachable units, the problem of pipeline clamps being fixed on the workbench and unable to move in the existing technology is solved. In use, the clamping table 1 can be installed at any position on the workbench as needed, or the installed clamping table 1 can be removed, its orientation or position adjusted, and then reinstalled on the workbench, meeting the needs of different operating scenarios. Installation and disassembly are more convenient, use is more flexible, and applicability is stronger.

[0036] The clamping assembly is configured to stably clamp the pipeline being processed, thus preventing axial rotation or movement of the pipeline during processing. The pipeline is typically a tubular structure of a certain length. When clamped on the clamping assembly, different parts of the pipeline face different directions. In this embodiment, by rotatably connecting the clamping assembly to the support, the pipeline can rotate relative to the support and clamping table 1 along with the clamping assembly, ensuring that the part of the pipeline to be processed faces the operator. This eliminates a significant amount of repetitive clamping, rotating, and re-clamping work, reducing the difficulty of operation for the operator.

[0037] In a specific embodiment, such as Figure 3 As shown, the clamping table 1 adopts a planar plate structure. The worktable has an installation surface. The clamping table 1 and the installation surface have corresponding bolt holes 11, so that the clamping table 1 can be installed on the worktable by bolts.

[0038] Furthermore, in this embodiment, as Figure 3 As shown, the support includes spaced-apart support plates 2 and pins 4. Both ends of the pins 4 are fixed to the top of the support plates 2, and the clamping assembly is rotatably connected to the pins 4. Specifically, the support is positioned in the middle of the clamping platform 1 to ensure balanced force distribution and improve the overall structural stability. Two parallel and spaced-apart support plates 2 are positioned between them, and the clamping assembly is connected to the support plates 2 via the pins 4. The assembly can rotate around the pins 4 to adjust the angle of the pipeline clamped on the clamping assembly.

[0039] Furthermore, in this embodiment, the support plate 2 is also provided with an arc-shaped limiting groove 21, which is centered on the pin 4. A limiting member 3 is slidably disposed in the arc-shaped limiting groove 21. The limiting member 3 passes through the clamping assembly and extends out of the arc-shaped limiting groove 21 to both sides, and its protruding end is provided with a fastener. The arc-shaped limiting groove 21 penetrates the thickness of the support plate 2, and its opening width is adapted to the limiting member 3. When the clamping assembly rotates around the pin 4, the limiting member 3 can slide freely in the arc-shaped limiting groove 21. At the same time, the two ends of the limiting member 3 respectively protrude out of the arc-shaped limiting groove 21 of the two support plates 2, and each protruding end is provided with a fastener. The shape of the fastener is larger than the opening of the arc-shaped limiting groove 21, so that it can be locked on the support plate 2 on the side of the arc-shaped limiting groove 21 away from the clamping assembly, so as to lock the limiting member 3 in a suitable position in the arc-shaped limiting groove 21.

[0040] Preferably, the fastener is threaded to the protruding end of the limiting member 3. By tightening the fastener, it can be clamped to the support plate 2, and sufficient friction is formed between the fastener and the support plate 2, making it difficult for the fastener to move, thereby fixing the limiting member 3 in the required position and thus locking the clamping component. When the angle of the clamping component is adjusted to the correct position, the clamping component can be kept in a fixed position by locking the fixing member 7, so that the operator can process the pipeline. By loosening the fixing member 7, the lock can be released, thereby allowing the support plate 2 to rotate around the pin 4, thereby adjusting the angle of the clamping component.

[0041] Furthermore, in this embodiment, the clamping assembly includes a support plate 5, which is placed between the support plates 2 and has a pin hole and a limiting hole 52; the pin 4 passes through the pin 4; the limiting member 3 passes through the limiting hole 52. The distance between the limiting hole 52 and the pin hole is equal to the distance between the arc-shaped slide groove 61 and the pin hole, so that when the support plate 5 is installed between the support plates 2, the limiting member 3 can pass through both the limiting hole 52 and the arc-shaped slide groove 61 at the same time. It can slide in the arc-shaped slide groove 61 as the support plate 5 rotates, and can also be fixed at a certain position in the arc-shaped slide groove 61 by fasteners to lock the support plate 5 and fix the angle of the clamping assembly.

[0042] In a preferred embodiment, the support plate 5 is symmetrically arranged with the line connecting the pin hole and the limiting hole 52 as the center line to ensure that the support plate 5 is subjected to balanced force; the arc-shaped slide 61 can be symmetrically or asymmetrically arranged with the vertical straight line where the pin 4 is located as the center line. The length of the arc-shaped slide 61 can be set according to the requirements to limit the extreme angle of rotation of the support plate 5, so as to ensure the stability and safety of the overall structure while meeting the usage requirements.

[0043] Preferably, there are two support plates 5, which are arranged opposite to each other between the two support plates 2. The limiting member 3 passes through both support plates 2 and both support plates 5, making the overall structure connection more stable and the locking more reliable.

[0044] Furthermore, in the embodiments of this application, such as Figure 4 , Figure 5 As shown, the clamping assembly also includes a base 6 and clamping members; the base 6 is vertically connected to the end of the support plate 5 away from the limiting hole 52; the clamping members are adjustablely positioned on the side of the base 6 away from the support plate 5. The clamping members are used to clamp the pipeline and are in direct contact with it. The distance between the two clamping members can be adjusted according to the outer diameter of the pipeline, allowing it to be used to clamp pipelines of various sizes. The base 6 and the limiting hole 52 are respectively located on both sides of the pin hole. When the limiting member 3 rotates around the pin hole, the base 6 also rotates synchronously around the pin hole, enabling the clamping member on the other side of the base 6 to rotate the pipeline to the required angle.

[0045] In one specific embodiment, the base 6 is a flat plate-shaped component, the support plate 5 is connected to one side of the base 6 plate, and the clamping member is connected to the other side of the base 6 plate. Preferably, the edge of the support plate 5 extending between the support plates 2 is arc-shaped and may include one or more arc-shaped edges to avoid the part of the support plate 5 protruding from the support plate 2 from rubbing against other components, tools or operators when the support plate 5 rotates around the pin 4, thus affecting work safety.

[0046] Furthermore, in an alternative technical solution of this embodiment, the clamping member includes a fixing member 7 and a sliding member 8. The fixing member 7 is fixed to one end of the base 6; the sliding member 8 is slidably connected to the base 6 to adjust the distance between the sliding member 8 and the fixing member 7. With this arrangement, when the sliding member 8 is close to the fixing member 7, a small gap is formed between the two, which can clamp pipelines with smaller diameters; by moving the sliding member 8 away from the fixing member 7, a larger gap is formed between the two, which can clamp pipelines with larger diameters, thereby achieving convenient adjustment of the distance between the two.

[0047] In one specific embodiment, the fixing member 7 and the sliding member 8 are plate-shaped components of the same size and structure, and both are vertically arranged on the plate surface of the base 6 away from the support plate 5.

[0048] Furthermore, in the above embodiment, the clamping assembly also includes a fixing block 10 and a lead screw 9. The fixing block 10 is disposed at the end of the base 6 away from the fixing member 7 and is threadedly connected to the lead screw 9; the end of the lead screw 9 near the fixing member 7 is connected to the sliding member 8. Preferably, the end of the lead screw 9 away from the fixing member 7 is provided with a handle 11. By rotating the handle 11, the lead screw 9 can be rotated relative to the fixing block 10. Since the lead screw 9 is threadedly connected to the fixing block 10, rotating the lead screw 9 can move the lead screw 9 relative to the fixing block 10 towards or away from the fixing member 7, thereby driving the sliding member 8 connected to the other end of the lead screw 9 to move towards or away from the fixing member 7. Through this setting, the positions of the lead screw 9 and the sliding member 8 can be continuously adjusted, and the threaded connection has a self-locking function, so that the lead screw 9 and the sliding member 8 can be fixed in the required position to prevent them from moving during the clamping of the pipeline and affecting operational safety.

[0049] Furthermore, in this embodiment, the base 6 is provided with a groove 61, and the bottom of the slider 8 is provided with a slider 81. The slider 81 is slidably connected to the groove 61 and engages with the groove 61. By providing the groove 61, the slider 8 can be limited from the bottom, so that it can only move along the groove 61, which further improves the stability of the slider 8; the slider can engage with the groove 61 during the movement along the groove 61, which can prevent the slider 8 from disengaging from the groove 61 during the sliding process, further improving the safety of the operation.

[0050] In one specific embodiment, the base 6 is a plate-shaped component with a certain length and width. The fixing member 7 and the fixing block 10 are respectively fixed at both ends of the base 6 along its length. The sliding groove 61 extends from the fixing block 10 toward the fixing member 7, penetrates the thickness of the base 6, and is set along the middle of the width direction of the base 6. The support plate 5 is symmetrically arranged on both sides of the sliding groove 61. A connecting rod is provided between the slider 81 and the sliding member 8. The shape of the connecting rod is smaller than the opening of the sliding groove 61 and can extend into the sliding groove 61. The shape of the slider 81 is larger than the opening of the sliding groove 61 and is placed outside the opening of the sliding groove 61 to achieve a snap-fit ​​with the sliding groove 61.

[0051] In a preferred embodiment, the end of the base 6 near the fixing member 7 is connected to the support plate 5. This arrangement allows the clamping position of the pipeline to correspond to the position of the support plate 5, so that the gravity of the pipeline and the impact force during processing can be directly transmitted to the support plate 5, and then to the support and clamping table 1, which is beneficial to improving the stability of the pipeline. At the same time, it allows the slide groove 61 to extend to a sufficient length so that the spacing of the clamping members has a large adjustable range.

[0052] Furthermore, in the embodiments of this application, both the fixing member 7 and the sliding member 8 adopt a two-section folding structure. For example... Figure 6 As shown, both the fixing member 7 and the sliding member 8 can be folded or unfolded along the direction perpendicular to the base 6, allowing them to be further adapted to the shape of the pipeline to be processed, especially when the pipeline diameter is large, thus improving the stability of the pipeline. For example, both the fixing member 7 and the sliding member 8 are formed by two flat plates connected by two-section pins 82, which is simple in structure and easy to manufacture and use.

[0053] Preferably, the side of the fixing member 7 and the sliding member 8 that contacts the pipeline is provided with an anti-slip layer.

[0054] In this embodiment, the clamping platform 1, support plate 2, support plate 5, base 6, fixing member 7, sliding member 8, fixing block 10, etc., can all be made of metal or wood. They can be processed in the factory according to a unified standard and then transported to the site for assembly, or they can be assembled in the factory and then transported to the site for overall installation on the workbench. Two or more adjustable clamps can be used to clamp the same pipeline to ensure that the pipeline is stably clamped.

[0055] The advantages and positive effects of this invention are:

[0056] (1) By detachably connecting the clamping table to the workbench, the problem that the pipeline clamp is fixed on the workbench and cannot be moved in the prior art is solved. It is more convenient to set or adjust the installation position of the clamping table according to the needs, meet the needs of different operation scenarios, and make installation and disassembly more convenient, use more flexible, and more applicable.

[0057] (2) By setting the clamping assembly to be rotatably connected to the support, the pipeline can rotate with the clamping assembly, making it easier to adjust the angle of the pipeline, saving a lot of repeated clamping, rotating and clamping work, and reducing the difficulty of operation for operators.

[0058] (3) The overall device has a simple structure, can be made from common materials on the construction site, is easy to assemble and convenient to use.
