Technical Field
[0001] This utility model belongs to the field of pipeline welding, and in particular relates to a grounding clamp tool and fixture for pipeline welding. Background Technology
[0002] When performing circumferential welding on pipes, the pipes are usually placed on a roller frame for welding. Before welding, a grounding clamp is usually installed on the pipes to ensure the welding operation is safe.
[0003] However, in engineering projects using grounding clamps, the following problems often exist: During the welding process, the grounding clamp usually rotates with the pipeline, causing the grounding wire to become tangled and knotted, resulting in damage to the grounding clamp and the grounding wire; at the same time, due to the weight or welding heat transferred to the grounding clamp, the fixing screws of the grounding clamp may loosen, causing the grounding clamp to deform and be damaged, and there is also a risk of falling and injuring personal safety.
[0004] Therefore, there is an urgent need to design a grounding clamp tool for pipe welding to solve the technical problems of grounding clamp deformation and cable knotting mentioned above. Utility Model Content
[0005] To address the technical problems mentioned in the background art, such as the grounding clamp causing the grounding wire to become entangled and knotted, and the grounding clamp deforming and being damaged, a grounding clamp tooling and fixture for pipe welding is provided to solve the above problems.
[0006] To achieve the above objectives, the specific technical solution of this utility model for a grounding clamp tool and fixture for pipe welding is as follows:
[0007] A grounding clamp for pipe welding includes a support mechanism with a connecting rod on the support mechanism. One end of the connecting rod is sleeved on the support mechanism, and the other end is provided with a clamping mechanism. The connecting rod can slide relative to the support mechanism. The clamping mechanism is used to clamp the side wall of the pipe. The support mechanism is located on the straight line of the pipe axis. The support mechanism can drive the clamping mechanism and the pipe to rotate through the connecting rod.
[0008] Furthermore, the support mechanism includes a support rod that passes through a guide sleeve, and the guide sleeve is connected to the end of the connecting rod near the support rod.
[0009] Furthermore, the support mechanism also includes a stop, which is mounted on the guide sleeve and can fix the support rod to the guide sleeve.
[0010] Furthermore, the end of the guide sleeve is provided with an L-shaped groove, and a stop is inserted through the L-shaped groove and the support rod so that the support rod is fixed to the guide sleeve and the stop can abut against the side wall of the L-shaped groove.
[0011] Furthermore, the guide sleeve and connecting rod are integrally formed.
[0012] Furthermore, the support rod and the connecting rod are set at an angle.
[0013] Furthermore, the clamping mechanism includes a first clamping arm, a second clamping arm, and a connecting arm that connects the first clamping arm and the second clamping arm.
[0014] Furthermore, the inner surfaces of both the first and second clamping arms are provided with serrations.
[0015] Furthermore, the clamping mechanism also includes a second locking component, which is disposed on the outside of the first clamping arm and / or the second support arm, for secondary clamping of the pipe.
[0016] A clamp, comprising the aforementioned grounding clamp fixture for pipe welding.
[0017] The grounding clamp fixture for pipe welding of this utility model has the following advantages: By setting the support mechanism on the central axis of the pipe, when the fixture drives the pipe to rotate through the clamping mechanism, the grounding clamp cable will not come into contact with the clamping mechanism, thus avoiding the grounding clamp cable from being entangled by the clamping mechanism. At the same time, the connecting rod can slide relative to the support mechanism, so that the length of the fixture can be adjusted to meet the needs of different working occasions.
[0018] The grounding clamp fixture for pipe welding of this utility model has the following advantages: This fixture enables workers to reduce damage to the pipe surface during welding, and protects the grounding clamp cable from being caught in the clamping mechanism or other components during grounding. While ensuring the pipe welding effect, it improves the safety of pipe welding. At the same time, the fixture shortens the rotation radius of the grounding wire connection, which can reduce the wear of the grounding clamp. Moreover, when the welding heat is transferred to the grounding clamp through the grounding clamp fixture for pipe welding, the heat loss is large, which can reduce the damage of welding heat to the grounding clamp.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0026] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.
[0027] The following is a reference to the appendix. Figure 1 To be continued Figure 2 This utility model describes a grounding clamp tool and fixture for pipe welding.
[0028] In related technologies, when performing circumferential welds on pipes, it is generally necessary to place the pipe on a roller frame for welding. Before welding, a grounding clamp is usually installed on the pipe to ensure the welding operation.
[0029] However, in engineering projects using grounding clamps, the following problems often exist: During the welding process, the grounding clamp usually rotates with the pipeline, causing the grounding wire to become tangled and knotted, resulting in damage to the grounding clamp and the grounding wire; at the same time, due to the weight or welding heat transferred to the grounding clamp, the fixing screws of the grounding clamp may loosen, causing the grounding clamp to deform and be damaged, and there is also a risk of falling and injuring personal safety.
[0030] Based on this, this embodiment provides a grounding clamp tool for pipe welding, such as... Figure 1 and Figure 2 As shown, the grounding clamp for pipe welding includes a support mechanism 10. A connecting rod is provided on the support mechanism 10. One end of the connecting rod is sleeved on the support mechanism 10, and a clamping mechanism is provided on the other end. The connecting rod can slide relative to the support mechanism 10. The clamping mechanism is used to clamp the side wall of the pipe. The support mechanism 10 is located on the straight line where the pipe axis is located. The support mechanism 10 can drive the clamping mechanism and the pipe to rotate through the connecting rod.
[0031] This grounding clamp for pipe welding places the support mechanism 10 on the central axis of the pipe. When the clamp rotates the pipe through the clamping mechanism, the grounding clamp cable will not come into contact with the clamping mechanism, thus preventing the grounding clamp cable from getting tangled in the clamping mechanism. At the same time, the connecting rod can slide relative to the support mechanism 10, making the length of the clamp adjustable to meet the needs of different working conditions.
[0032] Furthermore, such as Figure 1 As shown, the support mechanism 10 includes a support rod 101, which passes through a guide sleeve 202. The guide sleeve 202 is connected to one end of the connecting rod near the support rod 101.
[0033] Specifically, such as Figure 1 and Figure 2 As shown, a clamping part 102 is provided at the end of the support rod 101 away from the guide sleeve 202. The clamping part 102 is a protruding structure for connecting with the grounding clamp. In use, the grounding clamp can clamp the clamping part 102 on the support rod 101, thereby causing the support rod 101 to rotate around its axis, which in turn drives the pipeline to rotate.
[0034] In this embodiment, as Figure 2 As shown, baffles are fixedly provided on both sides of the clamped part 102 on the connecting rod 201, and the baffles can prevent the grounding clamp from falling off.
[0035] Furthermore, such as Figure 1 and Figure 2 As shown, the support mechanism 10 also includes a stop 203, which is installed on the guide sleeve 202 and can fix the support rod 101 to the guide sleeve 202.
[0036] Optionally, the stop 203 includes a nut snapped into a slot and a screw threadedly connected to the nut, wherein the screw passes through the guide sleeve 202 and is threadedly connected to the nut, thereby fixing the support rod 101 and preventing the support rod 101 from rotating or wobbling relative to the guide sleeve 202.
[0037] Furthermore, such as Figure 1 As shown, the end of the guide sleeve 202 is provided with an L-shaped groove 204. The stop member 203 passes through the L-shaped groove 204 and the support rod 101, so that the support rod 101 is fixed to the guide sleeve 202, and the stop member 203 can abut against the side wall of the L-shaped groove 204. By providing the L-shaped groove 204 on the guide sleeve 202, the stability of the stop member 203 is ensured, thereby preventing the stop member 203 from falling off the guide sleeve 202.
[0038] Specifically, the guide sleeve 202 is integrally formed with the connecting rod.
[0039] Optionally, in order to make the support rod 101 more stable, a first locking component 205 is provided at the end of the guide sleeve 202 where the L-shaped groove 204 is not provided. The first locking component 205 is used to fix the guide sleeve 202, the connecting rod and the support rod 101.
[0040] Specifically, a through hole or a threaded hole is provided on the connecting rod 201. The first locking component 205 is set as a screw. The screw can pass through the connecting rod 201 to fix the connecting rod 201, the connecting part and the guide sleeve 202 relatively. In addition, the screw can be easily replaced by the staff, thereby reducing costs.
[0041] Optionally, multiple first locking components 205 can be provided. In this embodiment, two locking components are provided, spaced apart along the axial direction of the guide sleeve 202.
[0042] Furthermore, the support rod 101 and the connecting rod 201 are set at an angle.
[0043] It should be noted that the different angles of the support rod 101 and the connecting rod 201 facilitate welding of different specifications and adapt to welding operations in different environments. For example, if the support rod 101 and the connecting rod 201 are set at 45°, the support rod 101 will usually extend into the pipe during welding, making it convenient for workers to hang welding tools on the support rod 101. When the pipe needs to bear different forces, the angles of the support rod 101 and the connecting rod 201 can also be adjusted to provide support for the pipe in different directions. Therefore, during manufacturing, workers can choose the appropriate angle for processing according to actual needs. In this embodiment, the support rod 101 and the connecting rod 201 are set perpendicular to each other to provide radial support for the pipe and ensure that the pipe has the highest stability during welding.
[0044] Furthermore, such as Figure 1 As shown, the clamping mechanism includes a first clamping arm 301, a second clamping arm 302, and a connecting arm 303 connecting the first clamping arm 301 and the second clamping arm 302. The first clamping arm 301 and the second clamping arm 302 are used to clamp the side wall of the pipe.
[0045] Furthermore, such as Figure 1 As shown, the inner surfaces of both the first clamping arm 301 and the second clamping arm 302 are provided with serrations. In order to facilitate clamping the pipe, the inner surfaces of the first clamping arm 301 and the second clamping arm 302 are provided with serrations to increase the friction between the first clamping arm 301 and the second clamping arm 302 and the pipe.
[0046] In some embodiments, the inner side of the first clamping arm 301 is provided with serrations, and the second clamping arm 302 is not provided with serrations; or, the inner side of the first clamping arm 301 is not provided with serrations, and the second clamping arm 302 is provided with serrations.
[0047] Furthermore, the clamping mechanism also includes a second locking component 304, which is disposed on the outside of the first clamping arm 301 and / or the second support arm, for secondary clamping of the pipe.
[0048] In some embodiments, the second locking assembly 304 includes a nut and a screw threadedly connected to the nut, the nut being fixed to the second clamping arm 302. Exemplarily, the nut is welded to the second clamping arm 302, the second clamping arm 302 having a through hole or a threaded hole, the screw threadedly engaging with the nut, and the screw being screwed into the interior of the second clamping arm 302, with the protruding bottom of the screw contacting the pipe to clamp it.
[0049] In some embodiments, to increase stability, multiple second locking components 304 may be provided. In this embodiment, such as... Figure 1 As shown, there are two second locking components 304.
[0050] This embodiment provides a clamp, including the aforementioned grounding clamp fixture for pipe welding. This clamp allows workers to reduce damage to the pipe surface during welding and protects the grounding clamp cable from being caught in the clamping mechanism or other components during grounding. While ensuring the welding effect, it also improves the safety of pipe welding. Furthermore, the clamp shortens the rotation radius of the grounding wire connection, reducing wear on the grounding clamp. Additionally, when welding heat is transferred to the grounding clamp through the pipe welding grounding clamp fixture, heat loss is minimal, reducing damage to the grounding clamp from welding heat.
