[0030] like Figure 1-Figure 5 As shown, the utility model provides an electromagnetic clamp for a pipe laying machine, comprising:

[0031] A lifting rod 1, wherein a first sliding rod 11 is disposed at the bottom of the lifting rod 1, and a first plug 12 is disposed at the lower end of the first sliding rod 11;

[0032] A crossbeam 2, wherein a first guide hole 21 and a second guide hole 22 are provided on the crossbeam 2;

[0033] The electromagnetic assembly 3 comprises an electromagnet 31, a connecting seat 32 and a second slide bar 33, wherein the connecting seat 32 is provided with a mounting hole 321, a second plug 34 is provided at the lower end of the second slide bar 33, and a third plug 35 is provided at the upper end of the second slide bar 33; the connecting seat 32 is provided on the electromagnet 31, the second slide bar 33 is inserted into the mounting hole 321, and a gap is formed between the outer wall of the second slide bar 33 and the outer wall of the second plug 34 and the hole wall of the mounting hole 321, the second slide bar 33 can move horizontally and vertically relative to the mounting hole 321, the second slide bar 33 can move horizontally and vertically relative to the mounting hole 321, and the second plug 34 is configured to restrict the second slide bar 33 from escaping from the mounting hole 321;

[0034] The first slide rod 11 passes through the first guide hole 21, the first plug 12 is configured to limit the first slide rod 11 from being separated from the first guide hole 21, the second slide rod 33 passes through the second guide hole 22, and the third plug 35 is configured to limit the second slide rod 33 from being separated from the second guide hole 22.

[0035] Specifically, a plurality of electromagnetic components 3 are arranged on the crossbeam 2 along its length direction as required, and the electromagnets 31 in the electromagnetic components 3 are energized to generate magnetic force to suck the oil pipe. The crossbeam 2 is connected to the first slide bar 11 disposed at the bottom of the lifting rod 1, and the first plug 12 disposed at the bottom of the first slide bar 11 can abut against the bottom of the crossbeam 2 to prevent the crossbeam 2 from detaching from the first slide bar 11. In addition, the crossbeam 2 can also slide up and down on the first slide bar 11 to meet the suction requirements of the bending cylinder.

[0036] As for the electromagnetic component 3 arranged on the beam 2, the electromagnetic component 3 is suspended and installed on the beam 2 through the second slide rod 33. The third plug 35 can limit the second slide rod 33 from escaping from the second guide hole 22, and the second slide rod 33 can also slide relative to the beam 2.

[0037] More importantly, the lower end of the second slide bar 33 is installed in the mounting hole 321 set on the connecting seat 32 through the second plug 34. The aperture of the mounting hole 321 is larger than the outer circumferential size of the second slide bar 33, thereby forming a gap between the second slide bar 33 and the mounting hole 321, and the second plug 34 in the mounting hole 321 can limit the second slide bar 33 from detaching from the mounting hole 321. In this way, the second slide bar 33 can move vertically up and down relative to the mounting hole 321 when in use, and can also move horizontally relative to the mounting hole 321, so that the electromagnet 31 can be tilted as a whole relative to the second slide bar 33.

[0038] In this way, for the electromagnets 31 distributed at both ends of the oil pipe. In the case where the end of the oil pipe is bent upward, after the electromagnet 31 at the end position contacts the oil pipe, the outer wall of the second slide bar 33 and the outer wall of the second plug 34 and the hole wall of the mounting hole 321 form a gap, so that the second slide bar 33 moves relative to the electromagnet 31, and at the same time, the second plug 34 moves relative to the electromagnet 31, so that the outer end of the electromagnet 31 tilts upward and the inner end tilts downward. In the case where the end of the oil pipe is bent downward, after the electromagnet 31 at the end position contacts the oil pipe, the outer wall of the second slide bar 33 and the outer wall of the second plug 34 and the hole wall of the mounting hole 321 form a gap, so that the second slide bar 33 moves vertically relative to the electromagnet 31, and at the same time, the second plug 34 moves relative to the electromagnet 31, so that the outer end of the electromagnet 31 tilts downward and the inner end tilts upward.

[0039] That is to say, after the electromagnet 31 is suspended on the second slide bar 33 through the second plug 34, the electromagnet 31 can move in the corresponding direction relative to the second slide bar 33 and the second plug 34 after being subjected to external force. The electromagnet 31 can swing arbitrarily within the set range, so that the electromagnet 31 at different positions can adjust its own inclination posture as needed, and can be more effectively attached to the surface of the oil pipe to increase the effective magnetic attraction area.

[0040] In actual use, the lifting rod 1 drives the crossbeam 2 to move downward so that the electromagnetic assembly 3 is close to the oil pipe below. For the bent oil pipe, when the electromagnet 31 of the electromagnetic assembly 3 on the crossbeam 2 is attached to the surface of the oil pipe, the surface of the oil pipe is tilted after the oil pipe is bent. At this time, the electromagnet 31 will be tilted at a certain angle relative to the second slide bar 33 so that the electromagnet 31 can be more effectively attached to the surface of the oil pipe. In this way, the phenomenon of unreliable absorption caused by the small effective adsorption area between the electromagnet 31 and the oil pipe can be reduced, thereby improving the reliability of use.

[0041] Compared with the prior art method that only relies on the tilting of the crossbeam 2, since the electromagnets 31 in the electromagnetic assembly 3 at different positions can be tilted according to the corresponding oil pipe position, it can ensure that the electromagnets 31 at different positions are more effectively attached to the surface of the oil pipe. In addition, compared with the method that only relies on the tilting of the crossbeam 2, for oil pipes with relatively curved ends, after the electromagnet 31 at one end is attached, the electromagnet 31 at the other end cannot be attached to the oil pipe. The present application uses the electromagnets 31 at different positions to adaptively adjust their own tilting direction according to the posture of the oil pipe to ensure that the electromagnets 31 at both ends of the oil pipe can more effectively absorb the oil pipe.

[0042] By setting a gap between the second slide bar 33 and the mounting hole 321, on the one hand, the second slide bar 33 can move relatively vertically in the mounting hole 321, and on the other hand, the second slide bar 33 can move relatively horizontally in the mounting hole 321. Therefore, in actual use, for oil pipes with larger bends, after the electromagnet 31 is attached to the surface of the oil pipe, due to the certain gap between the second slide bar 33 and the mounting hole 321, the electromagnet 31 can be deflected relative to the second slide bar 33, so that the electromagnet 31 can be more effectively attached to the surface of the oil pipe, thereby increasing the effective magnetic adsorption area between the electromagnet 31 and the oil pipe, so that the electromagnet 31 can be more effectively attached to the surface of the oil pipe to increase the magnetic attraction force of the electromagnet 31 on the oil pipe, thereby improving the reliability of the electromagnetic clamp for the pipe laying machine.

[0043] In one embodiment, the outer end surface of the second plug 34 is a curved surface structure; or, the outer end surface of the second plug 34 is a conical surface; or, the edge of the outer end surface of the second plug 34 is provided with a chamfered structure.

[0044] Specifically, since the electromagnet 31 can be tilted and deflected relative to the second slide bar 33, in order to increase the deflection angle of the electromagnet 31 relative to the second slide bar 33, the outer end of the second plug 34 is set to a structure with thinner sides and a curved surface in the middle, and the outer end surface is described as an example.

[0045] When the electromagnet 31 contacts the surface of the oil pipe, if the oil pipe is bent, the electromagnet 31 will adapt to the surface of the oil pipe and tilt. Since the outer end surface of the second plug 34 is an arc structure, the electromagnet 31 can deflect at a larger angle.

[0046] In order to facilitate the installation of the second slide bar 33, the installation hole 321 includes a first hole section 3211 and a second hole section 3212 connected in sequence, and a step surface 3213 is formed at the connection between the first hole section 3211 and the second hole section 3212;

[0047] The second plug 34 is located below the step surface 3213 , and a gap is formed between the outer wall of the second sliding rod 33 and the hole wall of the second hole section 3212 .

[0048] Specifically, the mounting hole 321 is a stepped hole structure as a whole, and has a first hole section 3211 and a second hole section 3212 with different apertures. The aperture of the first hole section 3211 is smaller than that of the second hole section 3212, so that a step surface 3213 is formed at the connection between the two. During assembly, the second slide bar 33 is inserted into the first hole section 3211 and extends to the second hole section 3212, and the second plug 34 is located in the second hole section 3212. The outer contour size of the second plug 34 is larger than the aperture of the first hole section 3211, so that the second plug 34 is restricted by the step surface 3213 to restrict the second slide bar 33 from escaping from the mounting hole 321.

[0049] In order to ensure that the electromagnet 31 can be firmly supported and installed by the second slide bar 33, the two ends of the electromagnet 31 are respectively provided with the connecting seats 32, and the second slide bar 33 is arranged on the connecting seats 32, and the two second slide bars 33 are arranged vertically side by side.

[0050] In another embodiment of the present application, a mounting bracket 23 is provided on the crossbeam 2 , a proximity switch 24 is provided on the mounting bracket 23 , a detection component 13 for cooperating with the proximity switch 24 is provided on the lifting rod 1 , and the detection component 13 is arranged above the crossbeam 2 .

[0051] Specifically, in order to accurately control the descending amount of the lifting rod 1 during the descending process of the lifting rod 1, after the electromagnet 31 is effectively adsorbed on the oil pipe, the lifting rod 1 is promptly controlled to stop descending, and a proximity switch 24 is provided on the crossbeam 2 through the mounting bracket 23. During use, after the electromagnet 31 is attached to the oil pipe, the lifting rod 1 continues to move downward, and after the second slide bar 33 slides relative to the crossbeam 2 and the connecting seat 32 abuts against the bottom of the crossbeam 2, the crossbeam 2 will slide relative to the first slide bar 11 at the bottom of the lifting rod 1, so that the detection component 13 gradually moves downward and approaches the proximity switch 24. In addition, after the proximity switch 24 detects the detection component 13, it will trigger the lifting rod 1 to stop moving downward, so as to avoid the permanent magnet being squeezed and damaged due to the continuous descent of the lifting rod 1.

[0052] In order to ensure that the crossbeam 2 can be lifted and lowered smoothly, two lifting rods 1 vertically arranged side by side are provided on the crossbeam 2 , and a proximity switch 24 is disposed on one side of each lifting rod 1 .

[0053] In some embodiments, a wiring shield 25 is further provided on the crossbeam 2 . The wiring shield 25 is provided on the crossbeam 2 and forms a wiring channel with the crossbeam 2 . The cables connected to the electromagnet 31 are arranged in the wiring channel.

[0054] Specifically, since a plurality of electromagnetic components 3 are arranged at the bottom of the beam 2, the electromagnet 31 in each electromagnetic component 3 needs to be powered by cables. In order to ensure the safety and reliability of cable wiring, a wiring shield 25 is provided on the beam 2 to protect the cables arranged on the beam 2.

[0055] In another embodiment, a storage slot 26 is further provided on the crossbeam 2 , the opening of the storage slot 26 is arranged upward, and the storage slot 26 is configured to store a cable drag chain.

[0056] Specifically, the cable drag chain disposed above the crossbeam 2 can be placed in the storage slot 26 disposed on the crossbeam 2 to facilitate storage of the cable drag chain.

[0057] The utility model also provides a pipe laying machine, including a movable frame, on which a driving mechanism is arranged, and also includes the electromagnetic clamp for the pipe laying machine; the lifting rod 1 is connected to the driving mechanism, and the driving mechanism is configured to drive the lifting rod 1 to move up and down.

[0058] Specifically, the pipe laying machine is provided with a frame, and the frame can move above the oil pipe, so as to drive the electromagnetic clamp to move above the specific oil pipe through the frame, and then the oil pipe is sucked by the electromagnetic clamp to perform the pipe laying operation.

[0059] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited to this. Any changes or substitutions that can be easily thought of by technicians familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
