Description

Technical Field

[0001] This utility model relates to the field of cable trough technology, and in particular to a cable conveying device. Background Technology

[0002] Horizontal cable troughs are widely used in the field of mobile horizontal drilling rigs in the oil industry. Since horizontal drilling rigs are equipped with a large number of electrical devices, many power cables and signal cables of different thicknesses need to be guided from the power distribution room to the horizontal motor. In order to ensure that the cables can move with the horizontal drilling rig when it moves, the conventional practice is to reserve a certain amount of cable and support and protect it with auxiliary devices such as horizontal cable troughs to avoid improper dragging during the movement of the drilling rig, which could cause the cables to break or be damaged. For example, a double-row cluster well rapid transfer drilling rig cable trough with patent number CN103061714B.

[0003] In practical applications, the power supply area is far from the drilling site, and due to the complex terrain in special areas, the cable cannot be transported to the drilling site in a straight line. In related technologies, when transporting cables in special terrain, it is also necessary to make special horizontal cable troughs according to the terrain to complete the cable transport, which is very troublesome and affects the construction period. Utility Model Content

[0004] The purpose of this utility model is to provide a cable conveying device that solves the problem that cable troughs in related technologies cannot meet the needs of actual drilling applications where the power supply area is far from the drilling site and there are special terrain features that make it inconvenient to convey cables.

[0005] This utility model is implemented as follows: a cable conveying device is installed between the power supply area and the drilling area for cable conveying, including a cable storage and transportation section, a guide rail extension section and a mobile device. At least one of each of the cable storage and transportation section, the guide rail extension section and the mobile device is provided. The cable storage and transportation section and the guide rail extension section are detachably connected. The mobile device can slide along the cable storage and transportation section and the guide rail extension section respectively.

[0006] The guide rail extension includes a straight segment and an arc segment, and at least one straight segment and one arc segment are provided. The two straight segments, the two arc segments, and the arc segment and the straight segment can be detachably connected.

[0007] Addressing the complex terrain where the power supply area and drilling area are far apart, and the irregular shape of the drilling area, this invention first arranges cable storage and transportation sections with cables along the area between the power supply area and the drilling area. Then, track extension sections are connected between the cable storage and transportation sections. Depending on the specific terrain, straight and curved sections can be freely combined to adapt to different complex terrains. Even at bends, curved sections can be used for adaptation, ensuring that the mobile equipment can drive the cable to complete the transportation on complex terrain. The cable transportation device is easy to assemble and transport, greatly improving work efficiency. Moreover, this invention can meet the drilling rig's drilling needs at different angles in the drilling area with a single installation.

[0008] A further improvement of this invention includes at least one support mechanism, which is arranged along the cable conveying direction and used to support both the straight segment and the curved segment. The support mechanism, arranged along the cable conveying direction, supports the guide rail extension segment, ensuring the connection stability of the guide rail extension segment.

[0009] A further improvement of this utility model is that the support mechanism includes a support frame and a cantilever, wherein the cantilever is disposed at the upper end of the support frame and extends in the horizontal direction;

[0010] A mounting bracket extending along the direction of the arc-shaped segment is provided above the arc-shaped segment, and the arc-shaped segment is attached to the cantilever via the mounting bracket. The arc-shaped segment is detachably connected to the support mechanism via the mounting bracket, allowing the arc-shaped segment to be suspended on the cantilever, which is convenient for assembly and disassembly and does not affect the cable transmission.

[0011] A further improvement of this utility model: a slot is formed on the cantilever, the slot extending along the cable conveying direction, and the hook-on part is hooked into the slot to limit the left and right sides of the arc-shaped segment. The slot is provided along the cable conveying direction, and the cable is placed in the slot of the cantilever to ensure left and right side limitation during cable conveying.

[0012] A further improvement of this utility model: Two opposing partitions are installed on the cantilever, forming the slot between the two partitions, and the tops of the two partitions open outward to form a guide portion. The slot is composed of two partitions, and the cable is clamped between the two partitions. To ensure ease of installation, an outwardly opening guide portion is provided at the top of the slot.

[0013] A further improvement of this utility model: The hanging part includes a hanging rod and vertical rods. The hanging rod is arranged along the extension direction of the arc-shaped segment. The hanging rod is connected to the arc-shaped segment through multiple vertical rods. A limiting space for the cantilever is formed between two adjacent vertical rods to limit the front and rear sides of the arc-shaped segment. The hanging rod extends in the same direction as the arc-shaped segment. The vertical rods are used to connect the hanging rod and the arc-shaped segment. When the arc-shaped segment is connected to the cantilever, the cantilever is locked between two adjacent vertical rods, ensuring the front and rear direction limitation of the arc-shaped segment.

[0014] A further improvement of this invention is that both ends of the straight segment and the curved segment are provided with detachable connecting parts. This facilitates the assembly of the straight segment and the curved segment according to complex terrain, thus adapting to cable transportation in complex terrain.

[0015] A further improvement of this utility model: a detachable limiting component at the end of the arc-shaped section. After the cable tray is fixedly connected to the monorail crane, the rollers of the monorail crane are installed on both sides of the guide rail extension section, and the limiting component prevents the monorail crane from sliding out of the guide rail extension section; when disassembly or transportation is required, the limiting component is removed, allowing the mobile device to return from the guide rail extension section to the cable storage and transportation section.

[0016] A further improvement of this invention: The mobile device includes a mobile trolley and a cable tray connected to the mobile trolley. The mobile trolley moves on the guide rail extension, causing the cable tray to move the cable.

[0017] A further improvement of this invention is that the cable storage and transportation section is equipped with multiple mobile devices for storing cables. During transportation, all cables are collected into the cable storage and transportation section, which is fitted with limit blocks to prevent the mobile devices from sliding. This facilitates transportation and effectively protects the cables.

[0018] The beneficial effects of this utility model are as follows: For complex terrains where the power supply area and drilling area are far apart, and for the complex and irregular conditions of the drilling area, this utility model first arranges cable storage and transportation sections with cables along the area between the power supply area and the drilling area. Then, track extension sections are connected between the cable storage and transportation sections. Depending on the specific terrain, straight and curved sections can be freely combined to adapt to different complex terrains. Even at bends, curved sections can be used for adaptation, ensuring that the mobile equipment can drive the cable to complete the transportation on complex terrain. The cable transportation device is easy to assemble and transport, greatly improving work efficiency. Moreover, this utility model can meet the drilling rig's drilling needs at different angles in the drilling area with a single installation.

[0019] The guide rail extension section of the drilling rig uses a combination of arc-shaped guide rails and support frames of a certain degree. This allows the cable to move and rotate with the drilling rig during translation and rotation, without needing to move any device to turn the cable to the other side of the well site. This solves the problem of cable translation during drilling, is convenient, eliminates the hassle of installation and disassembly, improves work efficiency, reduces manual operation, saves costs, and enables rapid rig movement. Besides being applicable to conventional translation drilling rigs, this invention can also be used for translation drilling rigs in well sites with limited space, complex and irregular drilling conditions.

[0041] In this embodiment, the support mechanism 4 is welded and is installed as a whole, which is convenient to install. It can be placed in place using a forklift or crane.

[0042] In this embodiment, the support mechanism 4 includes a support frame 41 and a cantilever 42, wherein the cantilever 42 is disposed on the upper end of the support frame 41 and extends in the horizontal direction;

[0043] A mounting portion 5 extending along the extension direction of the arc-shaped segment 21 is provided above the arc-shaped segment 21, and the arc-shaped segment 21 is mounted on the cantilever 42 through the mounting portion 5. The arc-shaped segment 21 is detachably connected to the support mechanism 4 through the mounting portion 5, and the arc-shaped segment 21 is suspended on the cantilever 42, which is convenient for disassembly and assembly and does not affect the transmission of the cable 6.

[0044] In this embodiment, a slot 43 is formed on the cantilever 42, extending along the conveying direction of the cable 6. The hooking part 5 is hooked into the slot 43 to limit the left and right sides of the arc-shaped segment 21. The cantilever 42 has a slot 43 along the conveying direction of the cable 6, and the hooking part 5 is hooked into the slot 43 of the cantilever 42, so that the arc-shaped segment 21 or the straight segment 25 can be hooked onto the cantilever 42, limiting the arc-shaped segment 21 or the straight segment 25 to the left and right; ensuring the stability of the cable 6 during the conveying process.

[0045] In this embodiment, when the guide rail extension 2 is installed with the support mechanism 4, the slot 43 plays a good limiting role, preventing the guide rail extension 2 from detaching from the support mechanism 4 during use.

The arc segment 21 is installed on the support mechanism 4 through the hook part 5, and the arc segment 21 is suspended on the support mechanism 4. This makes it convenient to install the mobile device 3. Moreover, the arc segment 21 can be installed on the support mechanism 4 by using a forklift or crane. The installation is convenient and easy to operate, and can be installed quickly.

[0049] In this embodiment, detachable connecting parts 22 are provided at both ends of the straight segment 25 and the arc segment 21. This facilitates free assembly of the straight segment 25 and the arc segment 21 according to complex terrain, adapting to the cable 6 transport in complex terrain.

The rigid pipe 26 used on the straight section 25 provides high strength and stability, while the flexible hose used on the arc-shaped section 21 facilitates installation and use.

[0060] The working principle of this utility model is as follows: During installation, the support mechanism 4 is first placed in position, and then a crane is used to clamp the guide rail extension section 2 into the slot 43 of the support mechanism 4 through the hook part 5. It can be quickly installed without alignment or hammering. After the monorail crane and the cable tray 32 are connected together with the pin shaft, the rollers are placed on the guide rail extension section 2. During disassembly, all cable trays 32 including cables 6 are moved into the cable storage and transportation section 1, and then the guide rail extension section 2 is disassembled. Only a crane is needed to complete the process. The support frame 41 and the straight section 25 and the arc section 21 of the guide rail extension section 2 are all disassembled for transportation, which takes up little space and saves costs. Therefore, this utility model solves the problems of complex assembly and difficult disassembly of traditional cable trays. The structure is reasonable and compact, convenient to use, stable and reliable. It can realize the rapid assembly and disassembly of the support frame 41 and the straight section 25 and the arc section 21 of the guide rail extension section 2, thus greatly improving work efficiency and realizing the rapid horizontal movement of the drilling rig.

[0061] The cable delivery device for the drilling rig uses a combination of an arc-shaped guide rail extension section 2 and a support frame 41, allowing the cable 6 to move with the drilling rig and rotate during rig translation and rotation. The cable 6 can be rotated to the other side of the well site without moving any other device, solving the problem of cable 6 translation during drilling. This is convenient, eliminates the hassle of installation and disassembly, improves work efficiency, reduces manual operation, saves costs, and enables rapid rig movement. Besides being applicable to conventional translational drilling rigs, this invention can also be used for translational drilling rigs in well sites with limited, complex, and irregular drilling conditions. The cable 6 delivery device and the drilling rig host layout of this invention are as follows: Figure 1 As shown.
