Description

Technical Field

[0001] This utility model relates to the field of oil and gas drilling technology, and in particular to a cable trough that is easy to install quickly. Background Technology

[0002] Currently, with the continuous advancement of drilling technology, drilling companies are placing increasingly higher demands on the rapid mobility of oil and gas drilling rigs. In deep well drilling, cables connect the control room and the drill platform to transmit large currents between the two; if the cables are exposed, they are prone to accidents due to wear or short circuits. Cable troughs, as bridges for cables at the well site, are widely used in oilfield drilling, well workover, and pressurized operations. Cable troughs protect cables through enclosed designs (such as metal covers or high-strength plastic shells) to effectively isolate them from external impacts.

[0003] However, existing technologies for installing cable trays on drilling platforms have consistently faced challenges, including difficulties in installation and low accuracy in positioning dimensions. Furthermore, the cable trays must be re-hoisted after each site relocation, a cumbersome process that hinders rapid installation and wastes construction time. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a cable trough that is easy to install quickly, which solves the problems of cumbersome installation and inconvenient transportation of existing cable troughs.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A cable trough that is easy to install quickly includes a support frame, which is installed on the electrical control room; a lower section of the cable trough is movably connected to the support frame, an upper section of the cable trough is movably connected to the end of the lower section of the cable trough away from the support frame, and a drilling platform is movably connected to the end of the upper section of the cable trough away from the lower section of the cable trough.

[0007] In this design, the lower and upper cable troughs are movably connected, and their height can be adjusted according to the raising and lowering of the drilling platform. During the lifting process of the drilling platform driven by the base at its bottom, the lower and upper cable troughs rotate with the base, extending into an extended state. When the base reaches its highest position, the lower and upper cable troughs simultaneously form a stable "Z"-shaped structure. During the lowering process, the lower and upper cable troughs rotate with the base. When the lowest position is reached, the connection point between the upper cable trough and the drilling platform is disconnected, and the upper and lower cable troughs fold into a folded state. After folding, they are fixed to the top of the electrical control room by a support frame for easy transportation.

[0008] Furthermore, the support frame includes a first portal frame and a second portal frame, both of which are installed on the electrical control room; a hinge seat is installed on the top of the first portal frame, and the hinge seat is hinged to the end of the lower cable trough via a first pin; a limit groove is installed on the top of the second portal frame, and the limit groove is used to limit the lower cable trough.

[0009] In this design, the lower cable trough is movably connected to the first portal frame via a hinged seat. When the height of the drilling platform changes, the lower cable trough rotates relative to the hinged seat to adapt to the height change. When the lower cable trough is lowered to its lowest position and the upper and lower cable troughs are folded, the lower cable trough is embedded in the limiting groove at the top of the second portal frame to ensure the stability of the lower cable trough during transportation.

[0010] Furthermore, the first portal frame includes two support columns, which are welded to both sides of the electrical control room; the tops of the two support columns are connected to crossbeams by bolts, and hinge seats are set on the crossbeams.

[0011] Furthermore, both the lower and upper cable troughs are equipped with hinged lugs at their ends, and the lower and upper cable troughs are rotatably connected by a second pin that passes through the hinged lugs.

[0012] Furthermore, a single lug plate is provided at one end of the upper cable trough that connects to the drill table surface, and a double lug plate is provided on one side of the drill table surface. The single lug plate and the double lug plate are rotatably connected by a third pin.

[0013] In this design, a single-ear plate and a double-ear plate are used to achieve a rotating connection, which allows for convenient and quick installation and disassembly.

[0014] Furthermore, a protective railing is installed at the top of the upper cable trough; a protective iron chain is installed between the protective railing and the drilling platform.

[0015] In this scheme, the drilling platform is located at a high position. When the upper cable trough is raised to approximately the same height as the drilling platform, laying cables on the upper cable trough is difficult and dangerous. Setting up guardrails can provide safety for workers. Since the upper cable trough and the drilling platform are connected movably, setting up protective chains will not interfere with the movement between the two, while also protecting the workers.

[0016] Furthermore, fixing lugs are provided at the top of the lower cable trough and at the bottom of the upper cable trough.

[0017] In this solution, when the lower cable trough and the upper cable trough are in a folded state, they are connected by a fixing lug to prevent the upper cable trough from springing up due to bumps during transportation.

[0018] Furthermore, several lifting lugs are installed on both the lower and upper sections of the cable trough.

[0019] In this design, lifting lugs are provided to facilitate hoisting using crane equipment during installation.

[0020] Furthermore, the lower and upper cable troughs are trough structures made of welded profiles, and the interior of the trough structure is used for laying cables.

[0021] The beneficial effects of this utility model are:

[0022] This utility model provides a cable trough that facilitates quick installation. During operation, the cable is installed in both the upper and lower cable trough sections at once. The upper and lower cable trough sections are extended according to the height of the drilling platform, eliminating the need to adjust the platform height and connect the upper cable trough to the platform each time, making installation convenient. For transportation, the upper and lower cable trough sections are lowered to their lowest position, folded in place. They are then fixed to the control room by a support frame and can be transported directly, making transportation convenient. The overall structure is rationally designed, with adjustable height during operation, and requires no disassembly or reassembly during relocation, saving significant time on cable trough disassembly or assembly.

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. The specific embodiments of the present invention are described below to facilitate understanding by those skilled in the art. However, it should be understood that the present invention is not limited to the scope of the specific embodiments. For those skilled in the art, various changes are obvious as long as they fall within the spirit and scope of the present invention as defined and determined by the appended claims. All inventions utilizing the concept of the present invention are protected.

[0033] like Figures 1-3 As shown, this embodiment provides a cable trough that is easy to install quickly. This cable trough can be extended according to the height changes of the drill platform, saving time for cable trough installation and disassembly; specifically, it includes:

[0034] Support frame 1, lower cable trough 3 and upper cable trough 4;

[0035] Among them, the support frame 1 is installed on the electrical control room 2; the lower cable trough 3 is movably connected to the support frame 1, the upper cable trough 4 is movably connected to the end of the lower cable trough 3 away from the support frame 1, and the drilling platform 5 is movably connected to the end of the upper cable trough 4 away from the lower cable trough 3.

[0036] like Figure 4 As shown, the support frame 1 includes a first portal frame 11 and a second portal frame 12, both of which are mounted on the electrical control room 2. A hinge seat 13 is mounted on the top of the first portal frame 11, and the hinge seat 13 is hinged to the end of the lower cable trough 3 via a first pin 14. A limiting groove 15 is mounted on the top of the second portal frame 12, which is used to limit the movement of the lower cable trough 3. The lower cable trough 3 is movably connected to the first portal frame 11 via the hinge seat 13. When the height of the drilling platform 5 changes, the lower cable trough 3 rotates relative to the hinge seat 13 to adapt to the height change. When the lower cable trough 3 is lowered to its lowest position and the upper cable trough 4 and lower cable trough 3 are folded, the lower cable trough 3 is embedded in the limiting groove 15 on the top of the second portal frame 12, ensuring the stability of the lower cable trough 3 during transportation.

[0037] The first portal frame 11 includes two support columns 16, which are welded to both sides of the electrical control room 2 respectively; the tops of the two support columns 16 are connected to a crossbeam 17 by bolts, and a hinge seat 13 is set on the crossbeam 17.

[0038] The structure of the second portal frame 12 is similar to that of the first portal frame 11, and the limiting groove 15 is provided on the crossbeam 17 of the second portal frame 12.

[0039] like Figure 6 As shown, both the lower cable trough 3 and the upper cable trough 4 are provided with hinged lugs 31 at their ends, and the lower cable trough 3 and the upper cable trough 4 are rotatably connected by a second pin 32 that passes through the hinged lugs 31.

[0040] like Figure 5 As shown, a single ear plate 41 is provided at one end of the upper cable trough 4 that connects to the drill platform 5, and a double ear plate 51 is provided on one side of the drill platform 5. The single ear plate 41 and the double ear plate 51 are rotatably connected by a third pin 42. The single ear plate 41 and the double ear plate 51 are rotatably connected, and the connection allows for convenient and quick installation and disassembly.

[0041] A guardrail 43 is installed on the top of the upper cable trough 4; a protective chain 44 is installed between the guardrail 43 and the drilling platform 5. Since the drilling platform 5 is located at a high position, laying cables 6 on the upper cable trough 4 becomes difficult and dangerous when the upper cable trough 4 is raised to approximately the same height as the drilling platform 5. The guardrail 43 provides safety for workers. Because the upper cable trough 4 and the drilling platform 5 are connected movably, the protective chain 44 does not interfere with their movement while simultaneously protecting workers.

[0042] like Figure 7 As shown, both the top of the lower cable trough 3 and the bottom of the upper cable trough 4 are provided with fixing lugs 33. When the lower cable trough 3 and the upper cable trough 4 are in a folded state, the fixing lugs 33 are used to connect the two to prevent the upper cable trough 4 from springing up due to bumps during transportation.

[0043] Both the lower cable trough 3 and the upper cable trough 4 are equipped with several lifting lugs 34; the lifting lugs 34 facilitate the use of crane equipment for lifting during the installation process.

[0044] The lower cable trough 3 and the upper cable trough 4 are trough structures made of welded profiles, and the inside of the trough structure is used to lay cables 6.

[0045] The working principle of this embodiment is as follows:

[0046] During operation, cable 6 is first installed in the upper cable trough 4 and the lower cable trough 3 at once; during the process of the base driving the drilling platform 5 to rise, the lower cable trough 3 and the upper cable trough 4 rotate with the rise of the base, and the upper cable trough 4 and the lower cable trough 3 are in an extended state; when the base is raised to the high position, the lower cable trough 3 and the upper cable trough 4 also form a stable "Z" shaped structure at the same time.

[0047] During transportation, the upper cable trough 4 and the lower cable trough 3 are lowered to their lowest positions, so that they are folded. At this time, the upper cable trough 4 and the lower cable trough 3 are fixed on the electrical control room 2 by the support frame 1, and then they can be transported directly. Transportation is convenient and there is no need to disassemble or reinstall them during transportation.

[0048] Those skilled in the art will recognize that the embodiments described herein are intended to help the reader understand the principles of this invention, and should be understood that the scope of protection of this invention is not limited to such specific statements and embodiments. Those skilled in the art can make various other specific modifications and combinations based on these technical teachings disclosed in this invention without departing from the essence of this invention, and these modifications and combinations are still within the scope of protection of this invention.
