Description

Technical Field

[0001] This utility model relates to the technical field of pipe lifting clamp devices, specifically to an adaptive pipe clamp for preventing loosening during pipe lifting. Background Technology

[0002] Pipeline hoisting is a crucial process in engineering fields such as construction, chemical engineering, and municipal engineering. It is used to transport and install long-distance, high-altitude pipelines. Among these tools, round pipe lifting clamps have become one of the most widely used hoisting tools in the industry due to their simple structure and convenient operation. Traditional round pipe lifting clamps mostly adopt a scissor-type structure, which uses the pulling force during hoisting to drive the lower clamping arm to automatically clamp the pipeline without the need for an additional locking mechanism. This makes them suitable for the hoisting needs of conventional short-distance, small-diameter pipelines.

[0003] However, existing pipe clamps have significant technical drawbacks: their clamp arm width is fixed and cannot be adaptively adjusted, resulting in a limited clamping contact range. When dealing with long pipes, the clamp arm structure limits the clamp's ability to precisely grip the pipe's center of gravity, easily leading to a deviation of the clamping point from the center of gravity. This causes the pipe to tilt or become unbalanced during lifting. This imbalance not only increases the local stress on the clamp arm but also compromises clamping stability, making the pipe prone to loosening and slipping during lifting and transport. Utility Model Content

[0004] (I) Technical Issues

[0005] This invention provides an adaptive pipe clamp for anti-loosening pipe hoisting, which solves the problem that traditional round pipe hoisting clamps are difficult to adapt to the center of gravity of long pipes due to the non-adjustable clamp arm width, thereby improving the stability and safety of long pipe hoisting.

[0006] (II) Technical Content

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: an adaptive pipe clamp for anti-loosening pipe hoisting, including a round pipe clamp, with right-angle clamps fixedly provided on the inner sides of the two clamping arms of the round pipe clamp, and telescopic rods fixedly provided on the front and rear sides of the two clamping arms of the round pipe clamp, with an adaptive clamp fixedly provided at the other end of the telescopic rod, and a driving mechanism for driving the adaptive clamp away from or close to the round pipe clamp fixedly provided on the outer side of the telescopic rod, and multiple roller assemblies provided on the side of the adaptive clamp that contacts the outer wall of the pipe.

[0008] Furthermore, the telescopic rod includes an outer rod fixedly disposed on the side of the cylindrical pipe clamp arm, and an inner rod inserted into the outer rod, with the adaptive clamp plate fixedly disposed at the outer end of the inner rod.

[0009] Furthermore, the drive mechanism includes an electric push rod fixedly disposed on the outside of the outer rod, and the piston end of the electric push rod is fixedly connected to one end of the inner rod.

[0010] Furthermore, the roller assembly includes a groove located inside the adaptive clamping plate, and a roller is rotatably disposed inside the groove, the roller contacting and rollingly connecting with the pipe.

[0011] Furthermore, the right-angle clamp and the adaptive clamp are arranged in parallel and clamp the pipe synchronously.

[0012] Furthermore, a rubber pad is fixedly provided on the side of the right-angle clamp that contacts the pipe.

[0013] Furthermore, both clamping arms of the round pipe clamp are straight arms, and a right-angle clamping plate is fixedly installed on the inner side of the straight arm.

[0014] (III) Technical Effects

[0015] The advantages of this utility model compared with the prior art are:

[0016] 1. The adaptive clamping plate is moved and adjusted by the telescopic rod and drive mechanism, which can flexibly adjust the clamping contact range according to the length of the pipeline, avoiding the problem of uneven weight caused by the fixed clamping arm of traditional lifting clamps, and adapting to the lifting needs of pipelines of different lengths.

[0017] 2. The right-angle clamp and the adaptive clamp clamp are parallel and synchronously clamp the pipe to form a double clamping structure. The rubber pad of the right-angle clamp increases the friction, and the adaptive clamp rolls against the outer wall of the pipe through the roller assembly to reduce friction. Even during hoisting, the position of the adaptive clamp can be easily adjusted to prevent uneven weight distribution and solve the problem of loosening and slipping during pipe lifting and transportation.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] Combined with appendix Figure 1 To be continued Figure 6 An adaptive pipe clamp for anti-loosening pipe hoisting includes a round pipe clamp 1. Right-angle clamping plates 2 are fixedly installed on the inner sides of both clamping arms of the round pipe clamp 1. Telescopic rods 3 are fixedly installed on the front and rear sides of both clamping arms of the round pipe clamp 1. An adaptive clamping plate 4 is fixedly installed at the other end of the telescopic rod 3. A driving mechanism for driving the adaptive clamping plate 4 away from or towards the round pipe clamp 1 is fixedly installed on the outer side of the telescopic rod 3. Multiple roller assemblies 5 are provided on the side of the adaptive clamping plate 4 that contacts the outer wall of the pipe. The right-angle clamping plates 2 and the adaptive clamping plates 4 are arranged in parallel and clamp the pipe synchronously. A rubber pad 7 is fixedly installed on the side of the right-angle clamping plate 2 that contacts the pipe. Both clamping arms of the round pipe clamp 1 are straight arms, and the right-angle clamping plate 2 is fixedly installed on the inner side of the straight arm.

[0029] In this embodiment, as a preferred technical solution, the telescopic rod 3 includes an outer rod 31 fixedly disposed on the side of the clamp arm of the round pipe clamp 1, and an inner rod 32 inserted into the outer rod 31. The adaptive clamping plate 4 is fixedly disposed at the outer end of the inner rod 32. The driving mechanism includes an electric push rod 6 fixedly disposed on the outside of the outer rod 31. The piston end of the electric push rod 6 is fixedly connected to one end of the inner rod 32.

[0030] In this embodiment, as a preferred technical solution, the roller assembly 5 includes a groove 51 disposed inside the adaptive clamping plate 4, and a roller 52 is rotatably disposed inside the groove 51. The roller 52 contacts and rolls with the pipe.

[0031] The working principle of this utility model is as follows: A drive mechanism controls the extension and retraction of the telescopic rod, which in turn drives the adaptive clamping plate to flexibly adjust the clamping range. Combined with the right-angle clamping plate, this forms a bidirectional synchronous clamping structure, preventing uneven weight distribution. Furthermore, the combination of friction enhancement and rolling resistance reduction ensures clamping stability while facilitating fine-tuning of the position, ultimately achieving safe hoisting of long pipelines. An electric push rod drives the inner rod to extend and retract along the outer rod, adjusting the relative distance between the adaptive clamping plate and the right-angle clamping plate to adapt to the pipeline length and cover the center of gravity. The adaptive clamping plate reduces contact friction through a roller assembly, and the dual clamping action prevents the pipeline from loosening. Simultaneously, the rolling characteristics of the roller assembly allow for fine-tuning of the clamping plate position during hoisting, further mitigating the risk of uneven weight distribution.

[0032] The working process of this utility model is as follows:

[0033] 1. Place the pipe to be hoisted between the two right-angle clamps 2 of the round pipe hoisting clamp 1. Connect the upper end of the round pipe hoisting clamp 1 to the external hoisting equipment. Start the hoisting equipment. The right-angle clamps 2 on the inner side of the two straight arms of the round pipe hoisting clamp 1 approach each other and fit against the outer wall of the pipe. The rubber pads 7 on the right-angle clamps 2 contact the surface of the pipe to form an initial clamp and prevent the pipe from shifting during subsequent adjustments.

[0034] 2. Based on the pipe length, start the electric push rod 6. The piston end of the electric push rod 6 pushes the inner rod 32 to extend outward along the outer rod 31, causing the adaptive clamping plate 4 fixed at the end of the inner rod 32 to move outward. By observing the horizontal state of the pipe, determine the position of the center of gravity. If the pipe is tilted, the extension and retraction of the inner rod 32 can be finely adjusted by the electric push rod 6 to adjust the position of the adaptive clamping plate 4 until the pipe is kept horizontal.

[0035] 3. The right-angle clamping plate 2 and the adaptive clamping plate 4 apply clamping force in parallel and synchronously, forming a double clamping structure. The right-angle clamping plate 2 increases the friction with the pipe through the rubber pad 7 to prevent the pipe from sliding axially; the adaptive clamping plate 4 makes rolling contact with the outer wall of the pipe through the roller 52 to reduce the frictional resistance during clamping and adjustment. Even if a slight imbalance is found before lifting, the position of the adaptive clamping plate 4 can still be finely adjusted by the electric push rod 6 to ensure the stability of the lifting.

[0036] 4. Continue to start the lifting equipment and use the round pipe clamp 1 to transfer the pipe. After the pipe is in place, the clamp arm of the round pipe clamp 1 is released. Then, the inner rod 32 is driven by the electric push rod 6 to retract into the outer rod 31, which drives the self-adaptive clamp 4 to reset. Finally, the round pipe clamp 1 is removed to complete the entire lifting operation.

[0037] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
