TECHNICAL FIELD

[0001] The present application relates to the technical field of pipe-in-pipe transportation, and particularly relates to a turnover frame and a continuous pipe transportation device. BACKGROUND

[0002] In recent years, with the gradual development of oil and gas wells, the well conditions are increasingly complex, and higher requirements are put forward for the specifications and performance of the coiled tubing. In order to meet the deep development of shale gas, there are currently multiple super-large pipe diameter coiled tubing devices in operation, which continuously improve the mining mode, so that the small pipe diameter and conventional length coiled tubing cannot meet the requirements of the process and well depth, and the large pipe diameter and super-long coiled tubing gradually become the trend of future development of coiled tubing.

[0003] When transporting the coiled tubing, firstly, the core shaft diameter of the drum needs to meet the standard requirements, and secondly, the size of the drum is constrained by transportation, and cannot be infinitely increased to meet the length requirement of the coiled tubing, so transportation becomes the biggest problem limiting the super-long and large pipe diameter coiled tubing.

[0004] At present, the common way to solve this problem is to increase the outer diameter of the drum, which can accommodate the super-long and large pipe diameter coiled tubing, but cannot solve the transportation problem. Increasing the outer diameter means increasing the delivery height, which cannot be transported under the premise of the height limit of domestic transportation. CONTENT OF THE INVENTION

The turnover frame includes a first state and a second state. When the turnover frame is in the first state, the first support frame supports the drum, and the drum is placed vertically. When the turnover frame is in the second state, the second support frame supports the drum, and the drum is placed horizontally.

[0010] In a possible implementation, the second support frame is provided in plurality, and the plurality of second support frames are arranged along the circumference of the roller.

[0011] In a possible implementation, the first support frame is provided in two, and the two first support frames are arranged at two ends of the roller in the axial direction, and the two first support frames are connected by the second support frame.

[0013] In a possible implementation, the second support frame is provided with an arc-shaped support surface at one end away from the roller, and the turnover frame can switch between the first state and the second state through the arc-shaped support surface.

[0014] In a possible implementation, the turnover frame further comprises a support leg, and the support leg is used to support the first support frame or the second support frame, so that the turnover frame is kept in the second state.

[0039] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0040] The following disclosure provides many different embodiments or examples for implementing different structures of the embodiments of the present application. In order to simplify the disclosure of the embodiments of the present application, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the embodiments of the present application. In addition, the reference numerals and / or letters in the embodiments of the present application can be repeated in different examples. Such repetition is for the purpose of simplification and clarity, and does not indicate the relationship between the various embodiments and / or settings discussed.

[0041] For the convenience of description, spatial relative terms can be used in the specification to describe the relative position relationship or movement condition of one element or feature with respect to another element or feature as shown in the drawings, such as "inner", "outer", "inboard", "outboard", "under", "below", "on", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the drawings. For example, if the device in the drawings is turned over or the posture is changed or the movement state is changed, the directional indications will also change accordingly, for example: the element described as "under" or "below" another element or feature will be oriented as "above" or "above" another element or feature. Therefore, the example term "below" can include both the upper and lower positions. The device can be additionally oriented (rotated by 90 degrees or in other directions) and the spatial relative relationship descriptors used in the specification are interpreted accordingly.

[0042] To solve the problems in the prior art, the application provides a turnover frame and a continuous pipe conveying device, which can effectively solve the problem of excessive height when a drum conveys an ultra-long large-diameter continuous pipe.

[0043] As shown in Figures 1-17 The application provides a turnover frame, which has a first support frame 1 and a hoisting part 2. The first support frame 1 is arranged at one end of the drum 7 in the axial direction and is used to support the drum 7 in the axial direction of the drum 7. The hoisting part 2 is used to connect a hoisting device, so that the turnover frame and the drum 7 can be switched between the vertical type and the horizontal type. Specifically, the vertical type of the drum 7 means that the axial direction of the drum 7 is along the vertical direction, and the horizontal type means that the circumferential direction of the drum 7 is along the horizontal direction. Specifically, the drum 7 has a continuous pipe wound thereon, and the drum 7 with the continuous pipe needs to be transported to the operation site of the oil and gas field for exploitation, and then the drum is matched with a pipe reverser at the operation site to complete the conveying and lowering of the continuous pipe through the pipe reverser.

[0044] In the application, the first support frame 1 is arranged at one side of the existing drum 7 in the axial direction, so as to support the drum 7 in the axial direction. The hoisting part 2 hoists and turns over the turnover frame together with the drum 7, so as to turn over the drum 7 from the horizontal type to the vertical type, thereby reducing the occupied space in the height direction of the drum 7, and effectively solving the problem of excessive height when the drum 7 conveys an ultra-long large-diameter continuous pipe.

[0045] In the related art, in recent years, with the gradual development of oil and gas wells, the well conditions are increasingly complex, and higher requirements are put forward for the specifications and performance of the coiled tubing. In order to meet the deep development of shale gas, currently there are multiple super large pipe diameter coiled tubing equipment operations, which makes the mining mode continue to improve, so the small pipe diameter, conventional length coiled tubing cannot meet the requirements of the process and well depth, and the large pipe diameter, super long coiled tubing gradually becomes the trend of future development of coiled tubing. When transporting the coiled tubing, firstly, the core shaft diameter of the roller 7 needs to meet the standard requirements, and secondly, due to the transportation restrictions, the size of the roller 7 is restricted, and cannot be increased infinitely to meet the length requirements of the coiled tubing, so transportation becomes the biggest problem restricting the super long large pipe diameter coiled tubing.

[0046] Currently, the common way to solve this problem is to increase the outer diameter of the roller 7, make a special delivery truck for transporting super long large pipe diameter coiled tubing, change the shape and structure of the transportation roller 7, etc. Increasing the outer diameter of the roller 7 can accommodate the super long large pipe diameter coiled tubing, but cannot solve the transportation problem. Increasing the outer diameter means increasing the delivery height, which cannot be transported under the premise of height limit in domestic transportation. Making a special delivery truck for transporting super long large pipe diameter coiled tubing can meet the transportation requirements, but the cost is greatly increased, and with the increase of the order quantity of super long large pipe diameter coiled tubing trucks, it means that more customized delivery trucks need to be made, which will greatly increase the cost and reduce the profit of enterprises, and is not conducive to the development of enterprises. Changing the shape and structure of the transportation roller 7, etc. needs to ensure that the roller 7 is adapted to the customer's on-site pipe unloader, otherwise even if it is transported to the operation site, the coiled tubing cannot be used for pipe unloading. Therefore, how to transport the super long large pipe diameter coiled tubing is still a problem to be solved.

[0047] Moreover, the current roller 7 needs to be placed vertically after being fully loaded with coiled tubing in order to ensure the stability of the structure of the roller 7 during transportation and use. If the fully loaded coiled tubing roller 7 is forcibly placed horizontally, it is easy to cause uneven stress on the roller 7 and deformation, affecting subsequent transportation and use.

[0048] In the embodiment of the present application, a turnover frame is provided, which is detachably connected with the roller 7. After the turnover frame is fixed with the roller 7, the first support frame 1 of the turnover frame can support one end of the roller 7 in the axial direction. The turnover frame is turned over through the lifting part 2 on the turnover frame. In the process of turning over, the first support frame 1 can support the axial direction of the roller 7, so as to avoid deformation of the roller 7 in the process of turning over. Thus, the roller 7 can be switched between vertical and horizontal positions. When the roller 7 needs to be transported, the roller 7 is placed horizontally by the turnover frame, so as to reduce the occupied space in the height direction and meet the transportation requirements. When transported to the construction site, the roller 7 is turned over to the horizontal position by the turnover frame, so as to cooperate with the pipe unloader for pipe feeding.

[0049] In some embodiments, at least one side of the first support frame 1 is larger than the diameter of the roller 7.

[0050] In the present application, by setting at least one side of the first support frame 1 to be larger than the diameter of the roller 7, the hoisting part 2 can be arranged outside the roller 7, thereby facilitating the switching of the roller 7 between the vertical and horizontal positions by the turnover frame.

[0051] In a specific embodiment, the first support frame 1 is square, and the side length of the first support frame 1 is greater than or equal to the diameter of the roller 7. When the roller 7 is placed horizontally, the roller 7 can be supported by one side, and the force acting on the first support frame 1 during the turnover process can reduce or avoid deformation of the roller 7. Specifically, the side length of the first support frame 1 is equal to the diameter of the roller 7, and when the roller 7 is placed horizontally, the first support frame 1 is hoisted to one end of the axial direction of the roller 7, i.e., the positioning between the first support frame 1 and the roller 7 is completed, facilitating the connection between the first support frame 1 and the roller 7. The hoisting part 2 is provided with four, and the four hoisting parts 2 are respectively located at the four corners of the first support frame 1, facilitating the connection with the hoisting equipment and ensuring the stability of the turnover frame and the roller 7 during the turnover process.

[0052] In some embodiments, the first support frame 1 is provided with a connecting part 3, and the connecting part 3 is used to connect the roller 7.

[0053] In the present application, by providing the connecting part 3 on the first support frame 1, the connecting part 3 is a fixed lug plate, and the fixed lug plate is provided with a fixed hole. After positioning the first support frame 1 at one end of the axial direction of the roller 7, the fixed lug plate and the diagonal support rectangular tube inside the roller 7 are fixed by tensioning the material. The number of fixed lug plates is multiple to ensure the reliability of the connection between the first support frame 1 and the roller 7. The tensioning material can be a chain tensioner, a packing belt, a sling, etc., without limitation.

[0054] As shown in FIG. 1, Figures 1-4 In a specific embodiment, the turnover frame only includes the first support frame 1, the four corners of the first support frame 1 are respectively provided with the hoisting part 2, the first support frame 1 is provided with the connecting part 3, the connecting part 3 is used to connect the turnover frame and the roller 7, and the hoisting part 2 is used for the turnover of the turnover frame and the roller 7.

[0055] As shown in FIG. 1, Figures 5-6As shown in the drawings, in some embodiments, the turnover frame further comprises a second support frame 4 connected with the first support frame 1, the second support frame 4 is arranged at the outer periphery of the roller 7 and is used to support the roller 7 along the radial direction of the roller 7, and the turnover frame comprises a first state and a second state, when the turnover frame is in the first state, the first support frame 1 supports the roller 7, and the roller 7 is placed vertically; when the turnover frame is in the second state, the second support frame 4 supports the roller 7, and the roller 7 is placed horizontally.

[0056] In the present application, by arranging the second support frame 4 at the outer periphery of the roller 7, when the turnover frame is in the first state, the first support frame 1 supports the roller 7, at this time the roller 7 is placed vertically and is used for transportation of the roller 7; when the turnover frame is in the second state, the second support frame 4 supports the roller 7, at this time the roller 7 is placed horizontally to ensure the supporting effect of the roller 7. When the roller 7 is switched between the vertical and horizontal positions, no interaction force is generated between the roller 7 and the hoisting equipment or between the roller 7 and the ground, further improving the protection of the roller 7. When the roller 7 is switched between the vertical and horizontal positions, the first support frame 1 and the second support frame 4 jointly support the roller 7.

[0057] Specifically, at this time, the first support frame 1 and the second support frame 4 are respectively provided with a hoisting part 2, and the turnover frame can be turned by selecting the hoisting part 2 connected with the hoisting equipment as needed.

[0058] As shown in the drawings, Figures 7-12 In some embodiments, the second support frame 4 is arranged in multiple numbers, and the multiple second support frames 4 are arranged along the circumferential direction of the roller 7.

[0059] In the present application, by arranging multiple second support frames 4, the multiple second support frames 4 are all connected with the first support frame 1, when the roller 7 is placed horizontally, only one second support frame 4 supports the roller 7, and the remaining second support frames 4 play a role in increasing the structural strength of the entire turnover frame, and when the turnover frame and the roller 7 are turned over, the remaining second support frames 4 can also play a role in assisting the support of the roller 7, avoiding the situation that the roller 7 slips due to unreliable connection between the turnover frame and the roller 7 during hoisting.

[0060] In a specific embodiment, the number of second support frames 4 can be two, three or four, each second support frame 4 is connected with one edge of the first support frame 1, playing a role in reinforcing the structural strength of the turnover frame.

[0061] Specifically, after the roller 7 is transported to the work site, the turnover frame can be cut to take out the roller 7 from the turnover frame, and the second support frame 4 of the turnover frame can also be arranged in an openable and closable form, and the roller 7 can be taken out from the turnover frame by opening the second support frame 4.

[0062] In some embodiments, two first support frames 1 are provided, and the two first support frames 1 are respectively arranged at two ends of the drum 7 in the axial direction, and the two first support frames 1 are connected by the second support frame 4.

[0063] In the present application, by providing two first support frames 1, the two first support frames 1 are respectively arranged at two ends of the drum 7 in the axial direction, and the two first support frames 1 are connected by at least one second support frame 4, the strength of the overall structure of the turnover frame can be further improved, and when the drum 7 is vertically placed, one of the first support frames 1 can be selected to support the drum 7. The first support frame 1 supporting the drum 7 is selected according to the actual loading position and angle, which is convenient for operation.

[0064] In some embodiments, the lifting part 2 is arranged on the first support frame 1 and / or the second support frame 4.

[0065] In the present application, the lifting part 2 can be arranged on the first support frame 1 and the second support frame 4 respectively, and the lifting position can be selected according to actual needs. Generally, four lifting parts 2 are selected during lifting to ensure the stability of the turnover frame during turnover, two of which are connected to one power end of the lifting equipment, and the other two are connected to the other power end of the lifting equipment, and the turnover of the turnover frame is completed by the lifting of the two power ends.

[0066] As shown in FIG. 1, Figures 13-17 In some embodiments, the end of the second support frame 4 away from the drum 7 is provided with an arc-shaped support surface 5, and the turnover frame can be switched between the first state and the second state through the arc-shaped support surface 5.

[0067] In the present application, by providing the arc-shaped support surface 5 at the end of the second support frame 4 away from the drum 7, the arc-shaped support surface 5 contacts the ground or the loading vehicle during the turnover of the turnover frame, assisting the turnover frame in the transition during the turnover process, and facilitating the switching of the turnover frame between the first state and the second state.

[0068] In some embodiments, the turnover frame further comprises a support leg 6, which is used to support the first support frame 1 or the second support frame 4, so as to keep the turnover frame in the second state.

[0069] In the present application, the first support frame 1 or the second support frame 4 can be assisted by the support leg 6, thereby ensuring the stability of the turnover frame in the second state. The support leg 6 is separately arranged from the first support frame 1 and the second support frame 4, and when the turnover frame needs to be kept in the second state, the first support frame 1 or the second support frame 4 is supported by the support leg 6; when the turnover frame needs to be turned over, the support leg 6 can be removed, and then the turnover frame is turned over by the arc-shaped support surface 5 of the second support frame 4.

[0070] In a possible implementation, the support leg 6 is arranged separately from the first support frame 1 or the second support frame 4.

[0071] Specifically, one end of the arc-shaped support surface 5 is provided with a support portion, and the support leg 6 supports the support portion, so that the turnover frame can be stably kept in the second state. The support leg 6 can be multiple or an integral support leg, which is not limited here. When the turnover frame in the second state needs to be supported, the first support frame 1 or the second support frame 4 can be supported by the support leg 6, and when the turnover frame needs to be turned to the second state, the support leg 6 is removed.

[0072] The turnover frame supports the roller 7 in the axial direction by arranging the first support frame 1 on one side of the roller 7 in the axial direction, and the roller 7 is hoisted and turned together with the turnover frame by the hoisting portion 2, so that the roller 7 can be turned from a horizontal type to a vertical type, thereby reducing the occupied space in the height direction of the roller 7, and effectively solving the problem of overheight of the roller 7 when transporting the super-long large-diameter continuous pipe.

[0073] The embodiment of the present application provides a continuous pipe transporting device, which comprises a roller and the above turnover frame. The continuous pipe is wound on the roller, and the roller can be switched between the horizontal type and the vertical type by the turnover frame, so as to switch the roller to a vertical placement state during transportation, reduce the occupied space in the height direction, and then transport the super-long large-diameter continuous pipe.

[0074] In the present application, the roller 7 and the turnover frame are arranged separately, and when the roller 7 needs to be transported, the roller 7 is connected with the turnover frame, and then the roller 7 is assisted by the turnover frame to be laid down from the horizontal type to the vertical type, thereby reducing the occupied space in the height direction and solving the problem of overheight of the super-long large-diameter continuous pipe. Moreover, the structure of the roller 7 itself can be protected by the turnover frame, so as to avoid the situation that the roller 7 is extruded and deformed due to uneven stress during the turnover process, and ensure the normal use of the roller 7. After being transported to the operation site, the roller 7 is turned from the vertical type to the horizontal type by the turnover frame, so as to cooperate with the pipe unloader at the operation site. Without changing the structure and shape of the roller 7 itself and without developing a special delivery vehicle for transporting the super-long large-diameter continuous pipe, the transportation of the super-long large-diameter continuous pipe can be completed, which is low in cost and convenient to operate.
