Description

[0002] During the process of oil well repair, a pipe laying mechanism is needed to send the oil pipe to the well repair platform or send it down to the platform for placement. The mechanization of domestic well repair operations has made great progress compared with the past. For example, disassembly, assembly and transportation have achieved the integration of lifting, loading and transportation.

[0003] In order to adapt the installation relationship between the oil pipe and the well repair platform, the length of the oil pipe needs to be measured to calculate the insertion length of the oil pipe.

[0072] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0073] refer to Figure 1-Figure 3 The present application proposes a pipe laying machine, which includes a cofferdam assembly 100, a track assembly 200 and a gantry assembly 300. The cofferdam assembly 100 is supported on the ground to provide a foundation for supporting the entire pipe laying machine. The track assembly 200 is arranged on both sides of the cofferdam assembly 100. The gantry assembly 300 is movably connected to the track assembly 200 and moves along the track assembly 200 to arrange the oil pipes 500.

[0074] The cofferdam assembly 100 is a frame structure arranged on the ground. Two detection members arranged opposite to each other are arranged on the cofferdam assembly 100, and a detection position is formed between the two detection members.

[0075] The two detection components can be fixedly supported at both ends of the cofferdam assembly 100 through detection brackets, or can be directly arranged on the track assembly 200 at both ends of the cofferdam assembly 100.

[0076] For ease of understanding, the length direction of the track assembly 200 is defined as the X direction, the length direction of the cofferdam assembly 100 is defined as the Y direction, and the height direction of the track assembly 200 is defined as the Z direction.

[0077] The detection element includes a first detection element 410 and a second detection element 420 which are arranged opposite to each other. The first detection element 410 and the second detection element 420 are both infrared or other structures capable of realizing distance detection.

[0078] For the convenience of detection, the first detection member 410 and the second detection member 420 are respectively located at a certain height from the cofferdam assembly 100 in the Z direction, that is, the detection position is formed at a certain height from the cofferdam assembly 100 .

[0079] The distance L between the first detection member 410 and the second detection member 420 is always known.

[0080] During the inspection, the gantry assembly 300 hoists the target oil pipe 500 and moves it along the X direction and the Z direction to the inspection position interval.

[0081] Then, the first detection member 410 detects the distance L1 between itself and the first end of the oil pipe 500 close to the first detection member 410, and the second detection member 420 detects the distance L2 between itself and the second end of the oil pipe 500 close to the second detection member 420. Then, the length L of the oil pipe 500 = Ltotal - L1 - L2, thereby obtaining the length of the oil pipe 500.

[0082] This detection method can improve the detection efficiency. Compared with the traditional measurement method in which one end of the oil pipe 500 must be moved to the starting position for measurement, the pipe laying machine involved in the present application can realize automatic detection of the oil pipe 500 by installing two detection parts on the basis of the structure of the existing pipe laying machine. The degree of automation and detection accuracy are higher, no human participation is required, and safety is stronger. It can be modified on the basis of the existing pipe laying machine, with lower cost, reduced cost of supporting mechanical devices, and reduced size of the entire equipment.

[0083] Next, the structure of the pipe laying machine is further described in detail:

[0084] Specific reference Figure 2 The cofferdam assembly 100 includes a main cofferdam assembly 110 and an auxiliary cofferdam assembly 120. The number of the auxiliary cofferdam assemblies 120 is set according to actual needs. The cofferdam assembly 100 is composed of the main cofferdam assembly 110 and the auxiliary cofferdam assembly 120, which is convenient for processing and transportation.

[0085] The main cofferdam assembly 110 and the auxiliary cofferdam assembly 120 are arranged in sequence, and the adjacent main cofferdam assemblies 110 and auxiliary cofferdam assemblies 120 and the auxiliary cofferdam assemblies 120 are connected by cofferdam buckle plates 130 .

[0086] A plurality of cross arm supports 140 are arranged at intervals along the length direction of the cofferdam assembly 100 for supporting the oil pipe 500 .

[0087] The track assembly 200 includes a first track assembly 201 and a second track assembly 202 arranged at both ends of the cofferdam assembly 100, and the first track assembly 201 and the second track assembly 202 both include a track fixing frame 210, a track folding frame 220 and at least one folding ear seat assembly 230 arranged along the height direction of the track fixing frame 210.

[0088] refer to Figure 1 For easy installation, the first detection member 410 and the second detection member 420 are respectively arranged on the track fixing frame 210 of the first track assembly 201 and the second track assembly 202 at a certain height from the cofferdam assembly 100 .

[0089] Specifically, the track fixing frame 210 includes a supporting frame 212 and a fixed track segment 211 horizontally arranged on the supporting frame 212 , and the bottom of the supporting frame 212 is fixed on the cofferdam assembly 100 .

[0090] The first detection member 410 and the second detection member 420 are respectively mounted on two oppositely disposed support frames 212 .

[0091] refer to Figure 4 The gantry assembly 300 involved in the present application includes a gantry 310, a moving assembly 320 and a lifting assembly 330. The two ends of the gantry 310 are movably connected to the first track assembly 201 and the second track assembly 202 along the X direction.

[0092] The moving assembly 320 can move along the length direction of the gantry 310 and along the Y direction. The lifting assembly 330 is connected to the moving assembly 320 and can be lifted and lowered relative to the moving assembly 320 .

[0093] The lower part of the lifting assembly 330 is connected to an electromagnetic assembly 340 , and the lifting assembly 330 drives the electromagnetic assembly 340 to move along the Z direction to adsorb the oil pipe 500 .

[0094] The movement of the oil pipe 500 is achieved through the gantry assembly 300. In order to achieve that the electromagnetic component 340 on the gantry assembly 300 can be more effectively attached to the surface of the oil pipe 500 to increase the magnetic attraction of the electromagnetic component 340 on the oil pipe 500 and thereby improve the reliability of the gantry assembly 300.

[0095] The moving assembly 320 includes a driving component 321, a transmission component 322 and a moving seat 323. The driving component 321 is connected to the gantry 310, and the moving seat 323 is connected to the driving component 321 through the transmission component 322. The moving seat 323 is movably connected to the gantry 310 under the action of the driving component 321.

[0096] The lifting component 330 includes a lifting drive component, a lifting rod 331, a cross beam 332 and a plurality of electromagnetic components 340 connected to the cross beam 332. The lifting drive component is fixed on the moving seat 323. The lifting rod 331 is connected to the output end of the lifting drive. The cross beam 332 is installed at the bottom of the lifting rod 331. The electromagnetic component 340 is arranged on the cross beam 332.

[0097] In order to improve the stability during the lifting process, two lifting rods 331 are provided, at least one lifting rod 331 is connected to the lifting drive member, and the cross beam member 332 is connected to the bottom of the lifting rod 331 .

[0098] The driving method and specific moving process of the moving assembly 320, the lifting assembly 330 and the gantry 310 are prior arts, which are not the design focus of this application and will not be described in detail here.

[0099] refer to Figure 5-Figure 8 , the connection of the electromagnetic assembly 340 in the lifting assembly 330 is described below:

[0100] A first sliding rod 333 is disposed at the bottom of the lifting rod 331 , and a first plug 334 is disposed at the lower end of the first sliding rod 333 .

[0101] The cross beam 332 is provided with a first guide hole and a second guide hole.

[0102] refer to Figure 7 , Figure 8 The electromagnetic assembly 340 includes an electromagnet 341, a connecting seat 342 and a second slide rod 343, the connecting seat 342 is provided with a mounting hole 3421, the lower end of the second slide rod 343 is provided with a second plug 345, and the upper end of the second slide rod 343 is provided with a third plug 344.

[0103] The connecting seat 342 is arranged on the electromagnet 341, and the second slide bar 343 is inserted into the mounting hole 3421. A gap is formed between the outer wall of the second slide bar 343 and the hole wall of the mounting hole 3421. The second slide bar 343 can slide vertically relative to the mounting hole 3421, and the second slide bar 343 can swing horizontally relative to the mounting hole 3421. The second plug 345 is configured to limit the second slide bar 343 from detaching from the mounting hole 3421.

[0104] The first slide rod 333 passes through the first guide hole, the first plug 334 is configured to limit the first slide rod 333 from being separated from the first guide hole, the second slide rod 343 passes through the second guide hole, and the third plug 344 is configured to limit the second slide rod 343 from being separated from the second guide hole.

[0105] Specifically, a plurality of electromagnetic assemblies 340 are arranged on the cross beam 332 along its length direction as required, and the oil pipe 500 is sucked by energizing the electromagnets 341 in the electromagnetic assemblies 340 to generate magnetic force.

[0106] The cross beam 332 is connected to the first slide bar 333 disposed at the bottom of the lifting rod 331, and the first plug 334 disposed at the bottom of the first slide bar 333 can abut against the bottom of the cross beam 332 to prevent the cross beam 332 from detaching from the first slide bar 333. In addition, the cross beam 332 can also slide up and down on the first slide bar 333 to meet the suction requirements of the bending cylinder.

[0107] As for the electromagnetic assembly 340 set on the cross beam 332, the electromagnetic assembly 340 is suspended and installed on the cross beam 332 through the second slide rod 343. The third plug 344 can limit the second slide rod 343 from detaching from the second guide hole, and the second slide rod 343 can also slide relative to the cross beam 332.

[0108] The lower end of the second slide bar 343 is installed in the mounting hole 3421 set on the connecting seat 342 through the second plug 345. The aperture of the mounting hole 3421 is larger than the outer circumferential size of the second slide bar 343, thereby forming a gap between the second slide bar 343 and the mounting hole 3421, and the second plug 345 in the mounting hole 3421 can limit the second slide bar 343 from detaching from the mounting hole 3421. In this way, the second slide bar 343 can slide vertically up and down relative to the mounting hole 3421 when in use, and can also swing horizontally relative to the mounting hole 3421, so that the electromagnet 341 can be tilted as a whole relative to the second slide bar 343.

[0109] In actual use, the lifting rod 331 drives the cross beam 332 to move downward, so that the electromagnetic assembly 340 is close to the oil pipe 500 below.

[0110] For the bent oil pipe 500, when the electromagnet 341 of the electromagnetic assembly 340 on the cross beam 332 is attached to the surface of the oil pipe 500, the surface of the oil pipe 500 is tilted after the oil pipe 500 is bent. At this time, the electromagnet 341 will be tilted at a certain angle relative to the second slide bar 343, so that the electromagnet 341 can be more effectively attached to the surface of the oil pipe 500.

[0111] In this way, the occurrence of unreliable absorption due to the small effective absorption area of ​​the electromagnet 341 and the oil pipe 500 can be reduced, thereby improving the reliability of use.

[0112] Compared with the prior art method of only relying on the tilting of the cross beam 332, since the electromagnets 341 in the electromagnetic assembly 340 at different positions can be tilted appropriately according to the corresponding parts of the oil pipe 500, it can ensure that the electromagnets 341 at different positions are more effectively attached to the surface of the oil pipe 500.

[0113] Moreover, compared with the method of only tilting the cross beam 332, for the relatively curved oil pipe 500 at both ends, after the electromagnet 341 at one end is attached, the electromagnet 341 at the other end cannot be attached to the oil pipe 500. However, the present application uses the electromagnets 341 at different positions to adaptively adjust their tilt directions according to the posture of the oil pipe 500, so as to ensure that the electromagnets 341 at both ends of the oil pipe 500 can more effectively absorb the oil pipe 500.

[0114] By setting a gap between the second slide bar 343 and the mounting hole 3421, on the one hand, the second slide bar 343 can slide relatively vertically in the mounting hole 3421, and on the other hand, the second slide bar 343 can swing horizontally in the mounting hole 3421. In actual use, for the oil pipe 500 with a larger bend, after the electromagnet 341 is attached to the surface of the oil pipe 500, due to the certain gap between the second slide bar 343 and the mounting hole 3421, the electromagnet 341 can be deflected relative to the second slide bar 343, so that the electromagnet 341 can be more effectively attached to the surface of the oil pipe 500, thereby increasing the effective magnetic adsorption area between the electromagnet 341 and the oil pipe 500, so that the electromagnet 341 can be more effectively attached to the surface of the oil pipe 500 to increase the magnetic attraction force of the electromagnet 341 on the oil pipe 500, thereby improving the reliability of the electromagnetic clamp for the pipe laying machine.

[0115] Specifically, the mounting hole 3421 is a stepped hole structure as a whole, and has a first hole section and a second hole section with different apertures. The aperture of the first hole section is smaller than that of the second hole section, so that a step surface is formed at the connection between the two. During assembly, the second slide bar 343 is inserted into the first hole section and extends to the second hole section, and the second plug 345 is located in the second hole section. The outer contour size of the second plug 345 is larger than the aperture of the first hole section, so that the second plug 345 is restricted by the step surface to restrict the second slide bar 343 from escaping from the mounting hole 3421.

[0116] refer to Figure 9-11 , the track assembly 200 is described in detail below:

[0117] Two groups of folding ear seat assemblies 230 are respectively arranged on the first track assembly 201 and the second track assembly 202 along the height direction corresponding to the track fixing frame 210 .

[0118] That is, the first track assembly 201 and the second track assembly 202 are arranged at intervals along the Y direction at both ends of the cofferdam assembly 100 .
