Description

Technical Field

[0001] The utility model relates to the technical field of electric power protection devices, in particular to a retractable cable transfer box. Background Art

[0002] The oil and gas industry is a mineral extraction industry that provides vital energy for the national economy. Production targets non-renewable oil and gas resources, and production activities primarily rely on underground oil and gas reserves. The production process includes the acquisition of mining rights, oil and gas exploration, oil and gas development, and oil and gas production. Drilling rigs are key facilities used for onshore drilling operations and play a vital role in the exploration and development of oil and gas resources. Equipped with advanced equipment and strict management measures, they ensure safe and efficient onshore drilling operations, making a significant contribution to the development of the energy industry.

[0003] A drilling rig typically consists of a drilling mast and related equipment. The mast is the core component of the platform, used to support and position the drilling equipment and ensure accurate drilling operations. During construction, the drilling crew needs to move the mast horizontally. This process shortens the platform's power and control cables, necessitating the lengthening of the associated electrical cables and control lines. To achieve this, the cable to be lengthened is first cut at one point, and then the ends of the new cable are connected to the cut end of the cable.

[0004] However, according to construction requirements, the cable connection points cannot be exposed on the ground. Cables exposed on the ground are susceptible to external physical damage and environmental influences, resulting in cable damage, electrical equipment failure, and even work stoppages, leading to casualties. Utility Model Content

[0005] The purpose of the utility model is to provide a retractable cable transfer box to solve the problem that the cable connection point is exposed on the ground, causing cable damage, electrical equipment failure, and even work stoppage and production, resulting in casualties.

[0006] In order to achieve the above-mentioned purpose, the basic solution provided by the utility model is: a retractable cable transfer box, comprising box body one, several connecting frames, box body two and a telescopic frame, wherein box body one and box body two are each provided with a box door on one side, and several connecting frames are connected side by side through the telescopic frame, and the two connecting frames located on the outermost sides are respectively connected to box body one and box body two through the telescopic frame, and pulleys with brake pads are fixedly connected to the four corners of the bottom of box body one, connecting frame and box body two.

[0007] The working principle of the present invention is as follows: when it is necessary to splice the cable protection boxes, first place box body one and box body two back to back, then place several connecting frames between box body one and box body two, then hinge the telescopic frame between box body one, box body two and each connecting frame, then the staff pushes box body two to move toward box body one, box body two drives the connecting frame between box body one and box body two to move, and the telescopic frame hinged between box body one, box body two and each connecting frame is folded, and when the telescopic frame hinged between box body one, box body two and each connecting frame is completely folded, the splicing of the cable protection boxes can be completed.

[0008] When the cable needs to be lengthened, first cut the cable to be lengthened at one point, then open the box doors of box one and box two, then pass the two ends of the cut cable through the box doors of box one and box two respectively, then connect one end of the new cable to the end of the cable to be lengthened in box one, then pass the other end of the new cable through box one, the connection frame and box two and connect it to the other end of the cable to be lengthened in box two. At the same time, ensure that the two connectors on the cable line are located in box one and box two respectively.

[0009] When the length of the extended cable is greater than the distance between box one and box two, the staff first pushes box two in the opposite direction relative to box one. At this time, the telescopic frame hinged between box one, box two and each connecting frame is stretched. When the two connectors on the cable line are respectively located in box one and box two, the pushing is stopped. When the telescopic frame hinged between box one, box two and each connecting frame is fully stretched, if the length of the extended cable is still greater than the distance between box one and box two, a new connecting frame is added between box one, box two and each connecting frame, and is hinged through the telescopic frame until the two connectors on the cable line are respectively located in box one and box two.

[0010] When the cable does not need to be protected, the staff first pushes box two toward box one, and box two drives the connecting frame between box one and box two to move. The telescopic frame hinged between box one, box two and each connecting frame is folded, and the telescopic frame hinged between box one, box two and each connecting frame is completely folded.

[0011] The beneficial effects of the present invention are as follows: by providing the box body and the connecting frame, the cable can be effectively protected in the box body when the cable needs to be lengthened, preventing external factors from damaging the cable, and the wiring points are not exposed, which effectively guarantees the safety during the construction process, extends the service life of the cable, and improves the safety and reliability of the cable; by providing the connecting frame and the telescopic frame, the distance between the box body and the connecting frame can be changed according to the length of the wiring, ensuring that both ends of the cable wiring are located in the box body and the connecting frame.

[0012] Option 2 is the preferred option of the basic option. Connecting seats and connecting rods are respectively provided on both sides of box body one and box body two. Connecting seats and connecting rods are provided on both sides of each connecting frame. The two adjacent connecting seats and connecting rods are connected by pins. Connecting seats and connecting rods are provided on box body one, connecting frame and box body two to facilitate mutual limitation.

[0013] Option three is the preferred option of the basic option. Each of the box doors includes a main box door and a cable door. Each of the main box doors is hinged to box one and box two, and one end of the cable door is hinged to the main box door.

You only need to pass the extended cable through the cable door.

[0014] Option 4 is a preferred option of the basic option. A locking unit is provided on the box door. The locking unit is provided on the box door to facilitate limiting the box door.

[0015] Option 5 is a preferred option of Option 4. The locking unit includes a locking rod and a through-slot plate. Both ends of the through-slot plate are detachably connected to the main box door, and the locking rod is slidably connected to the through-slot plate.
