[0002] Coiled tubing equipment has been hailed as a "universal equipment" and is widely used in oil and gas field workover, drilling, completion, logging and other operations. The roller is a storage and transportation device for coiled tubing, which is used to evenly wind the coiled tubing. During operation, the tubing is placed in a suitable delivery position, which can not only effectively reduce damage to the tubing, but also greatly improve the safety and convenience of the operation. The existing roller vehicle mainly adjusts the delivery position of the tubing through the pipe arrangement mechanism. However, due to the limited adjustment angle of the pipe arrangement mechanism, the pipe arrangement mechanism cannot adjust the tubing to a suitable delivery position under conditions such as small well sites. During the transportation process, the tubing is very likely to be damaged, and the pipe arrangement mechanism is very likely to break due to excessive force.

[0003] Therefore, it is necessary to provide a new lifting roller vehicle to solve the above-mentioned technical problems. Utility Model Content

[0034] The utility model provides a lifting roller vehicle, aiming to solve the problem that the existing roller vehicle cannot adjust the oil pipe to a suitable conveying position.

[0035] The embodiment of the utility model provides a lifting roller vehicle, such as Figure 1 , Figure 2 and Figure 4 As shown, the lifting roller vehicle includes a chassis 100, a roller mechanism 200, a lifting mechanism 300 and a pipe-discharging mechanism 400. The roller mechanism 200 includes a mounting seat 210 and a roller 220. The mounting seat 210 is arranged on the chassis 100, and the roller 220 is rotatably arranged on the mounting seat 210; the lifting mechanism 300 is arranged on the chassis 100, and the lifting mechanism 300 is connected to the mounting seat 210 to drive the mounting seat 210 to rise and fall; the pipe-discharging mechanism 400 is rotatably arranged on the mounting seat 210, and the pipe-discharging mechanism 400 has a pipe hole 431 for the oil supply pipe to pass through.

[0036] In this embodiment, the pipe arrangement mechanism 400 is rotatably arranged on the mounting seat 210. By rotating the pipe arrangement mechanism 400 and adjusting the position of the pipe arrangement mechanism 400, the delivery position of the oil pipe can be adjusted; the lifting mechanism 300 is used to drive the mounting seat 210 to rise and fall, and then drive the roller 220 to rise and fall. The lifting mechanism 300 drives the roller 220 to rise and fall to cooperate with the pipe arrangement mechanism 400 to adjust the delivery position of the oil pipe, so that the pipe arrangement mechanism 400 can still adjust the oil pipe to a suitable delivery position even under the working condition of limited site. In the prior art, the adjustment of the delivery position of the oil pipe is mainly achieved by the pipe arrangement mechanism 400. However, under the working condition of limited site such as a small well site, due to the limitation of the adjustment angle of the pipe arrangement mechanism 400, the oil pipe cannot be adjusted to a suitable delivery position. In the process of delivering the oil pipe, the oil pipe is very easy to be damaged, and the pipe arrangement mechanism 400 is very easy to break due to excessive force. The lifting roller vehicle drives the roller 220 to rise and fall through the lifting mechanism 300, and adjusts the height position of the roller 220 to cooperate with the pipe laying mechanism 400 to adjust the conveying position of the oil pipe, so that the pipe laying mechanism 400 can still adjust the oil pipe to a suitable conveying position even under working conditions with limited space such as a small well site, which can effectively protect the oil pipe and avoid damage to the oil pipe during transportation. At the same time, it can also improve the force applied to the pipe laying mechanism 400 and avoid breakage of the pipe laying mechanism 400.

[0037] It should be noted that, in the present embodiment, the chassis 100 is provided with an accommodating space, the mounting seat 210 is accommodated in the accommodating space, and the lifting mechanism 300 can drive the mounting seat 210 to rise and fall in the accommodating space. Furthermore, in order to ensure the stability of the mounting seat 210 when it is raised and lowered in the accommodating space, a guide block can be provided on the chassis 100, a guide rod can be provided on the mounting seat 210, and the guide rod can be passed through the guide block.

[0038] like Figure 1 and Figure 2 As shown, there are two lifting mechanisms 300, which are respectively arranged obliquely on both sides of the drum 220; and one end of each lifting mechanism 300 is rotatably connected to the chassis 100, and the other end is rotatably connected to the mounting seat 210. The two lifting mechanisms 300 are respectively arranged obliquely on both sides of the drum 220, and the two lifting mechanisms 300 act simultaneously to drive the mounting seat 210 to rise and fall, thereby driving the drum 220 to rise and fall, which can ensure the stability of the lifting mechanism 300 when driving the drum 220 to rise and fall. At the same time, in order to further ensure the stability of the drum 220 when it is raised and lowered, the lifting mechanisms 300 on both sides can be set as multiple or at least one obliquely set lifting mechanism 300 can be set around the mounting seat 210 according to actual needs during design.

[0039] like Figure 1As shown, each lifting mechanism 300 includes a cylinder body 310 and a telescopic rod 320 telescopically arranged in the cylinder body 310. The end of the cylinder body 310 away from the telescopic rod 320 is rotatably connected to the chassis 100, and the end of the telescopic rod 320 away from the cylinder body 310 is rotatably connected to the mounting seat 210. The lifting roller vehicle adopts a telescopic oil cylinder or a telescopic air cylinder to drive the mounting seat 210 to rise and fall, and then drives the roller 220 to rise and fall. The oil cylinder and the air cylinder have the characteristics of simple structure and good stability, which can simplify the structure of the lifting roller vehicle, and at the same time, can ensure the stability of the lifting mechanism 300 when driving the roller 220 to rise and fall. In addition, other methods such as electric cylinders can also be used to drive the roller 220 to rise and fall.

[0040] like Figure 2 As shown, the chassis 100 is provided with a distance sensor 110, and the distance sensor 110 is connected to the lifting mechanism 300 by electrical signals. In this embodiment, the distance sensor 110 is installed on the side of the chassis 100 close to the wellhead, and is used to measure the distance between the lifting roller vehicle and the wellhead, and the distance sensor 110 can maintain linkage with the lifting mechanism 300, and rely on the measured distance information to extend or retract the lifting mechanism 300 to a specific length, thereby raising or lowering the roller 220 to a suitable height position. According to the distance information measured by the distance sensor 110, the extension and retraction of the lifting mechanism 300 are adjusted to raise or lower the roller 220 to a suitable height position, which can cooperate with the pipe arrangement mechanism 400 to adjust the oil pipe to a suitable conveying position to avoid damage to the oil pipe during the conveying process, and can also improve the force of the pipe arrangement mechanism 400 to avoid the breakage of the pipe arrangement mechanism 400.

[0041] like Figure 1 and Figure 2 As shown, the lifting roller vehicle also includes a crawler 500, which is movably arranged on the chassis 100. Through the crawler 500 movably installed on the chassis 100, the staff can adjust the lifting roller vehicle to a suitable horizontal position before the operation, which can improve the convenience of the lifting roller vehicle and solve the problem of inconvenience in the movement of the roller vehicle in the prior art; at the same time, the movement of the lifting roller vehicle is realized by the crawler 500, which can cooperate with the lifting mechanism 300 and the pipe arrangement mechanism 400 to adjust the oil pipe to a more suitable conveying position to avoid damage to the oil pipe during the conveying process, and can also improve the force of the pipe arrangement mechanism 400 to avoid the breakage of the pipe arrangement mechanism 400. Further, the number of crawlers 500 is four, and the four crawlers 500 are arranged on the chassis 100 in a rectangular shape. The movement of the lifting roller vehicle is realized by four crawlers 500, which can improve the stability of the lifting roller vehicle when it moves.

[0042] like Figure 1 and Figure 2As shown, the chassis 100 is provided with four support rods 120, and the four support rods 120 are respectively provided at the four corners of the chassis 100. When the lifting roller vehicle is moved to a suitable horizontal position by the crawler 500, the staff can adjust the height position of the support rod 120 so that the support rod 120 abuts against the ground, thereby supporting the entire lifting roller vehicle to ensure the stable position of the lifting roller vehicle when conveying the oil pipe.

[0043] like Figures 3 to 5 As shown, the pipe arrangement mechanism 400 includes a bracket 410, a slider 420 and a conveying block 430. The bracket 410 is rotatably arranged on the mounting seat 210, the slider 420 is slidably arranged on the bracket 410 along the axis direction of the roller 220, and the conveying block 430 is arranged on the slider 420, and the conveying block 430 is provided with a pipe delivery hole 431. In this embodiment, the oil pipe is wound on the roller 220 in a multi-layer stacked form. When conveying the oil pipe, the slider 420 can slide along the axis direction of the roller 220 according to the position of the oil pipe, so that the oil pipe is always conveyed in a direction perpendicular to the axis of the roller 220, which can effectively protect the oil pipe and avoid damage to the oil pipe during the conveying process; the pipe delivery hole 431 is provided for the oil pipe to pass through, so as to provide guidance and lubrication for the conveying of the oil pipe.

[0044] like Figure 1 , Figure 3 and Figure 5 As shown, the mounting base 210 is provided with a vertical pole 211, the bracket 410 is rotatably connected to the vertical pole 211, and the vertical pole 211 is provided with a telescopic cylinder 212, and one end of the telescopic cylinder 212 away from the vertical pole 211 is rotatably connected to the bracket 410. The rotation of the bracket 410 is driven by the telescopic cylinder 212, and the telescopic cylinder 212 can be an oil cylinder or an air cylinder, which has the characteristics of simple structure and good stability, can simplify the structure of the lifting roller vehicle, and can also ensure the stability of the pipe arrangement mechanism 400 when rotating.

[0045] like Figure 5 As shown, the bracket 410 is provided with a screw rod 411 extending along the axis direction of the drum 220, and the slider 420 is engaged with the screw rod 411. The slider 420 is driven to slide along the axis direction of the drum 220 by the screw rod 411 transmission. The screw rod 411 transmission has the characteristics of simple structure and good stability, which can simplify the structure of the lifting drum vehicle and ensure the stability of the slider 420 when sliding along the axis direction of the drum 220.

[0046] In this embodiment, if Figure 4As shown, a roller 421 and a counter 422 are also provided on the slider 420. The counter 422 is connected to the roller 421. The roller 421 abuts against the oil pipe passing through the pipe hole 431. When the oil pipe is transported, the contact friction between the oil pipe and the roller 421 will cause the roller 421 to rotate. The counter 422 can record the length of the oil pipe in real time according to the rotation of the roller 421, so that the staff can observe and record the transportation length of the oil pipe in real time.

[0047] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
