Description

Technical Field

[0001] The utility model relates to the field of cable laying technical equipment, in particular to an adjustable bracket for laying submarine cables. Background Art

[0002] Submarine cables are an effective means of transmitting signals and power underwater, and are also an important branch of the field of underwater engineering technology. Before laying, submarine cables are coiled in the cable drum of the cable-laying ship. The coiled cables will produce inherent rotational stress, which requires that some method be adopted to release the circular rotation force of the coils one by one when laying the submarine cables to prevent the accumulation of cable torque. There are two main types of devices currently used for releasing torque during the storage and retraction of submarine cables: one is a pull-up detwist device, and the other is a rotary detwist device. Among them, the rotary detwist device uses power to drive the rotary cable storage device to release the torque of the submarine cable, and then transports the cable through the cable guide. In the prior art, in order to reduce the friction resistance during cable transportation, a cable bracket is usually set between the cable guide and the traction machine, and the cable bracket bears the cable gravity and drag friction resistance during transportation.

[0003] A row of cable brackets is usually arranged on the hull of the prior art, and a row of cable brackets includes a plurality of single brackets. The structure of the existing single bracket includes two vertical support frames, and two horizontal rollers are rotatably arranged between the two vertical support frames; the fore and aft ends of the two vertical support frames are fixedly connected by a connecting plate, and two vertical rollers are rotatably arranged between the two connecting plates on one side of the two horizontal rollers. A conveying space for the cable to pass through is formed between the two horizontal rollers and the vertical rollers.

[0004] When a rotary back-twist device is used to release the torque of the submarine cable, since the position of the traction machine is fixed, it is necessary to continuously move the cable guide back and forth to keep it synchronized with the rotary back-twist device. While the cable guide is moving, the staff needs to adjust the position of the bracket according to the changing cable length, and in order to avoid increasing friction during cable transportation due to uneven spacing between adjacent brackets, the staff needs to keep the spacing between adjacent brackets uniform after position adjustment. However, the existing brackets are separate and adjacent brackets are not connected. It is not only time-consuming for the staff to move the bracket, but also requires a lot of physical strength. Moreover, the staff cannot ensure that the spacing between adjacent brackets after adjustment is uniform. Utility Model Content

DETAILED DESCRIPTION

[0024] The technical solution of the present invention is further elaborated in detail below in conjunction with specific embodiments. Parts that are not described in detail in the following embodiments of the present invention, such as adjacent hinged connectors that are short connecting rods are hinged together by locking members, etc., should be immediately known to or should be known to those skilled in the art.

[0025] Example 1

[0026] like Figure 1-3 As shown, an adjustable bracket for laying submarine cables comprises two rows of rolling bases 1, a plurality of brackets 2 and hinged connectors 3. Each row of rolling bases 1 is composed of five rolling bases 1 arranged at intervals, the number of rolling bases 1 is ten, and the number of brackets 2 is the same as the number of rolling bases 1, so the number of brackets 2 is ten.

[0027] The rolling base 1 includes a trapezoidal base 101, an L-shaped mounting plate 102, and two rollers 103. The base 101 is welded and fixed to one side plate of the L-shaped mounting plate 102 near its inner side. Two mounting holes (not shown in the figure) are provided on the other side plate of the L-shaped mounting plate 102 along its length direction, and bearings are installed in each of the mounting holes. The two rollers 103 are rotatably mounted on the outer side of the other side plate of the L-shaped mounting plate 102 after the rotating shaft passes through the corresponding bearings.

[0028] The bracket 2 is welded and fixed on the base 101 of the corresponding rolling base 1 in the vertical direction. The bracket 2 is a cylindrical long rod. A lower connecting plate 4 and an upper connecting plate 9 are arranged between the two brackets 2 arranged side by side. The upper connecting plate 9 is arranged at a position close to the upper end of the corresponding bracket 2, and the lower connecting plate 4 is located directly below the upper connecting plate 9. The arrangement of the upper connecting plate 9 and the lower connecting plate 4 not only improves the stability of the connection between the two brackets 2 arranged side by side, but also forms a conveying space for conveying cables between the upper connecting plate 9 and the lower connecting plate 4 and the corresponding bracket 2.

[0029] A fixing plate 6 is disposed on the inner side of each bracket 2 between the upper connecting plate 9 and the lower connecting plate 4. Two supports 8 are disposed on both sides of the fixing plates 6 on the two brackets 2 arranged side by side and spaced along the length direction thereof. The supports 8 are disposed at positions close to the ends of the corresponding fixing plates 6. The supports 8 include a fixing seat and an L-shaped roller support plate. The fixing seat is welded and fixed to the fixing plate 6. One side plate of the L-shaped roller support plate is fixed to the fixing seat by bolts. The other side plate of the L-shaped roller support plate can be disposed opposite to the L-shaped roller support plate on the other support 8.

[0030] A lower horizontal roller 5 is rotatably arranged between the two L-shaped roller support plates at the lower end of the left side surfaces of the two fixed plates 6, and an upper horizontal roller 10 is rotatably arranged between the two L-shaped roller support plates at the upper end of the left side surfaces of the two fixed plates 6. The rotation of the upper horizontal roller 10 and the lower horizontal roller 5 can reduce the friction resistance during cable transportation.

[0031] A vertical roller 7 is rotatably arranged between two supports 8 on the right side of each fixed plate 6. The arrangement of the vertical roller 7 can reduce the friction resistance generated by the contact between the vertical roller 7 and the bracket 2 during cable transportation through its rotation. The arrangement of the vertical roller 7 can also prevent the cable from escaping from the transportation space during cable transportation when the upper connecting plate 9 is not arranged.

[0032] A rotating shaft 302 is provided in the middle of each bracket 2, one end of the rotating shaft 302 is located outside the corresponding bracket 2, and the other end is located inside the corresponding bracket 2. One end of each hinged connector 3 is rotatably disposed on the corresponding bracket 2 through the rotating shaft 302, and the hinged connector 3 is a short connecting rod 301. A short connecting rod 301 is rotatably disposed at both ends of the rotating shaft 302 on the first and last brackets 2 of each row, and two short connecting rods 301 are rotatably disposed at both ends of the rotating shaft 302 on the remaining brackets 2, and two corresponding short connecting rods 301 on the same side of adjacent brackets 2 are hingedly connected through a locking member.

[0033] The cable tray is connected by hinged connection of hinged connectors 3 on two adjacent brackets 2, so that the length of the cable tray can be adjusted by extension or contraction according to the change of cable length, and the spacing between adjacent brackets 2 can be ensured to be uniform after the length adjustment, so that the length and position of the cable tray can be quickly adjusted, thereby reducing the friction resistance of the cable tray during transportation.

[0034] The specific implementation method of the utility model is as follows: first, the cable is passed through the conveying space on the cable bracket composed of the lower connecting plate 4, the corresponding bracket 2 and the upper connecting plate 9. When the length of the cable changes according to the position of the cable guide, the staff can adjust the length of the cable bracket by stretching or contracting to change the distance between adjacent brackets 2.

[0035] The above is a basic implementation method of the utility model, and further improvements, optimizations and limitations can be made on the above basis to obtain the following embodiments:

[0036] Example 2

[0037] This embodiment is an improved solution based on the embodiment 1. Its main structure is the same as that of the embodiment 1. The improvement is as follows: Figure 4-5As shown, the articulated connection 3 includes a short connecting rod 301 and a long connecting rod 303. A short connecting rod 301 is rotatably set at both ends of the rotating shaft 302 on the two rows of the first and tail end brackets 2, and a long connecting rod 303 is rotatably set at both ends of the rotating shaft 302 on the remaining brackets 2, and the middle part of the long connecting rod 303 is set on the corresponding rotating shaft 302.
