Technical Field

[0001] The invention belongs to the technical field of oil and gas drilling equipment, and in particular relates to a vertical folding and retracting cable device. Background Art

[0002] When the oil electric drive drilling rig is drilling in cluster wells, the mainframe of the drilling rig needs to move between the wellheads of the cluster wells, while the power system module of the drilling rig is usually fixed at the well site. Therefore, the power and control cables between the mainframe of the drilling rig and the power system module of the drilling rig need to be retracted and released to adapt to the movement of the mainframe of the drilling rig. At present, most drilling rigs use large-capacity adjustable rail-type cable installation and storage brackets for cable retraction and release. Although this device meets the problem of cable retraction and release, it has the following shortcomings: First, due to the limitations of transportation height and length, the capacity of the cable still cannot meet the requirements of cluster well construction technology; second, the workload of bundling and fixing the cables before transportation is large, and during transportation, the cables and the cables and the cable storage rack structures are prone to collision with each other, causing cable damage. Summary of the invention

[0003] The object of the present invention is to provide a vertical folding cable retracting device, which has the characteristics of large cable capacity and reliable position limiting.

[0004] The technical solution adopted by the present invention is a vertical folding cable retractable device, comprising a chain-type main frame composed of short-span universal wheel vertical brackets and long-span universal wheel vertical brackets arranged alternately, a cable bin for retracting the chain-type main frame, and a guide base one and a guide base two for support and guidance, a connecting bracket is hinged between the short-span universal wheel vertical bracket and the long-span universal wheel vertical bracket, a connecting ear seat is fixedly connected to the inner wall of the cable bin, one end of the chain-type main frame is hinged to the connecting ear seat, one end of the guide base one is connected to the cable bin, and the other end is connected to the guide base two.

[0007] The connecting component is a connecting ear plate or an ear seat.

[0008] When the chain-type main frame is folded, a group of cross beams of the short-span universal wheel vertical bracket is located on the inner side of a group of cross beams of the long-span universal wheel vertical bracket.

[0009] The short-span universal wheel vertical bracket and the long-span universal wheel vertical bracket have the same length and the length is smaller than the inner width of the cable bin.

[0010] The guide base 2, the guide base 1 and the cable bin form a skid-type structure, and the top surface of the guide base 2 and the top surface of the guide base 1 are both at the same height as the bottom surface of the cable bin.

[0023] The short-span universal wheel vertical bracket 1, the long-span universal wheel vertical bracket 3 and the connecting bracket 2 are all sheet-like frame-type structural members with connecting ear plates or ear seats at both ends. The short-span universal wheel vertical bracket 1, the long-span universal wheel vertical bracket 3 and the connecting bracket 2 have the same height. A group of parallel cross beams are fixedly connected to the bottom of the short-span universal wheel vertical bracket 1 and the bottom of the long-span universal wheel vertical bracket 3, and universal wheels are arranged at both ends of the cross beams. During assembly, the short-span universal wheel vertical bracket 1, the connecting bracket 2, the long-span universal wheel vertical bracket 3, the connecting bracket 2, the short-span universal wheel vertical bracket 1, and the long-span universal wheel vertical bracket 3 are alternately arranged and connected together by hinged means using pins to form a vertical foldable cable retractable chain main frame. When the chain main frame is folded, a group of cross beams of the short-span universal wheel vertical bracket 1 are located on the inner side of a group of cross beams of the long-span universal wheel vertical bracket 3, such as Figure 3 As shown, the cables are fixed on each universal wheel vertical bracket and the connecting bracket 2 in order from low to high.

[0024] like Figure 4 As shown, the cable bin 6 is placed on the ground of the drilling rig site, the chain main frame is folded and stored in the cable bin 6, and the cable bin 6 and the vertical foldable cable chain main frame and cables thereon are hoisted and transported as a transport unit.

[0025] The short-span universal wheel vertical bracket 1 and the long-span universal wheel vertical bracket 3 have the same length and are smaller than the inner width of the cable bin 6 .

[0026] The guide base 1 5 and the guide base 2 4 are also placed on the ground of the drilling rig well site for support and guidance. The guide base 2 4, the guide base 1 5 and the cable bin 6 form a skid structure, and the top surface of the guide base 2 4 and the top surface of the guide base 1 5 are both at the same height as the bottom surface of the cable bin 6. The cross section of the guide base 1 5 is square or trapezoidal, and guide baffles 8 are provided on both sides of the guide base 1 5 and the guide base 2 4.

[0027] When the cable is retracted or released toward the left side of the cable bin 6, the guide base 2 4, the guide base 1 5 and the cable bin 6 are placed side by side in order from left to right, and the foldable and retractable cable chain main frame is located above the guide base 2 4, the guide base 1 5 and the cable bin 6; when the cable is retracted or released toward the right side of the cable bin 6, the guide base 2 4, the guide base 1 5 and the cable bin 6 are placed side by side in order from right to left.

[0028] The vertical folding cable retracting device of the present invention, the specific process of using the vertical folding cable retracting device to release the cable to the left side is as follows: the first short-span universal wheel vertical bracket 1 on the left side first rotates around the left hinge point of the first connecting bracket 2 on the left side connected thereto, and the first short-span universal wheel vertical bracket 1 on the left side is supported on the guide base 5 by four universal wheels and moves to the left side; then, under the pulling of the first short-span universal wheel vertical bracket 1 on the left side and the first connecting bracket 2 on the left side, the first long-span universal wheel vertical bracket 3 on the left side rotates around the left hinge point of the second connecting bracket 2 on the left side connected thereto, and the first long-span universal wheel vertical bracket 3 on the left side is supported on the cable bin 6 and the guide base 5 by four universal wheels and moves to the left side, and so on, according to the cable length requirements, the cables are released to the left side in sequence from left to right.

[0029] After the drilling is completed by placing the cable to the left, the specific process of using the vertical folding cable retracting device to retract the cable into the cable bin is as follows: the first connecting bracket 2 on the right is connected to the connecting ear seat 7 fixed to the cable bin 6 by a hinged manner, and the first long-span universal wheel vertical bracket on the right is pulled to rotate around the left hinge point of the first connecting bracket 2 on the right connected thereto, and the first long-span universal wheel vertical bracket 3 on the right is supported on the cable bin 6 by four universal wheels and moves to the right until the first long-span universal wheel vertical bracket 3 on the right is received in the initial position; At the same time, under the pulling of the first long-span universal wheel vertical bracket 3 on the right, all the released universal wheel vertical brackets and connecting brackets 2 move to the right with the first long-span universal wheel vertical bracket 3 on the right, and then, the first long-short span universal wheel vertical bracket 3 on the right is pulled to rotate around the left hinge point of the second right connecting bracket 2 connected to it, and the first short-span universal wheel vertical bracket on the right is supported by four universal wheels on the cable bin and moves to the right, and so on, until the first short-span universal wheel vertical bracket 1 on the left is received in the cable bin 6.

[0030] The process of laying out and retracting the cables to the right using the vertical folding cable-releasing and retracting device is similar to the process of laying out and retracting the cables to the left.

[0031] The vertical folding cable retracting device of the present invention is suitable for oil drilling rigs and well repairing rigs of various specifications and driving types.

[0032] The vertical folding cable retracting device of the present invention uses the vertical folding cable retracting device to retract and release cables. After multiple cables are arranged side by side, the plane formed by the center lines of the cables changes from being parallel to the well site foundation surface to being perpendicular to the well site foundation surface, and the cable capacity changes from being limited by the height to being limited by the width of the cable bin. The domestic transportation width limit is 3.75 meters, which is larger than the height limit of 3 meters. When the length of the cable bin is the same, it is beneficial to expand the cable capacity; a universal wheel vertical bracket supported on the cable bin is used to support and fix the cable, and the support of the cable changes from high-position support to low-position support, which is beneficial to weight reduction of the structural parts of the folding cable retracting device; the cables have more fixed bundling points on each universal wheel vertical bracket and the connecting bracket, and the positioning between each universal wheel vertical bracket and the cable bin is reliable, which solves the problems of large workload of bundling and fixing cables before transportation in the prior art and easy collision between cables and cables and cables and cable storage rack structural parts during transportation, causing cable damage.
