Crane cable chain systems, as a type of cable conveyor system, offer advantages such as precise guidance, good cable protection, and long service life.

[0003] The front beam of a knuckle boom crane is mainly divided into two sections with two hinge points. When the front beam is raised, the overall height is relatively low, which is of great significance for ports with strict height restrictions. However, due to the special structural design of the knuckle boom crane, the hinge point positions have an angle when designing the cable carrier main beam, and conventional arrangements are difficult to meet the design requirements.

[0004] Specifically, due to the unique structural design of the articulated boom crane, which has both a landside hinge point and a seaside hinge point on the front main beam, the landside hinge point of the front main beam is located at a counter-clockwise angle, allowing for a conventional disconnect design. However, the seaside hinge point of the front main beam is located at a clockwise angle, making a conventional design unsuitable.

[0005] Therefore, the inventors of this application have designed a folding boom crane cable chain system and a cable conveying system including the same, in order to overcome the above-mentioned technical problems. Summary of the Invention

[0012] According to one embodiment of the present invention, the first end of the second cable chain groove is connected to the first cable chain groove via a rotating component, and the second cable chain groove is rotatable around the first cable chain groove.

[0031] Furthermore, the invention should be understood not only through the actual terminology used, but also through the meaning implied by each term.

[0032] like Figure 1 As shown, this invention discloses a cable chain system for a folding boom crane, including a cable chain bracket 10 and a cable chain main beam 20. A cable chain is disposed within the cable chain main beam 20, and the cable chain main beam 20 is fixed to the cable chain bracket 10. Figure 2 As shown, the cable chain bracket 10 is fixedly connected to a frame structure by a first angle steel 11 and a second angle steel 12, for example by welding. At least one diagonal bracing angle steel 13 is fixed to the first angle steel 11, and the diagonal bracing angle steel 13 is located in the direction of the cable chain bracket 10 towards the trolley.

[0033] Preferably, two diagonal bracing angle steels 13 are fixed to the first angle steel 11, and the diagonal bracing angle steels 13 and the first angle steel 11 are preferably arranged in a triangular structure. The diagonal bracing angle steels 13 can increase the stiffness in this direction, reduce the swaying of the drag chain main beam 20, and thus extend its service life.

[0034] like Figure 3 and Figure 4 As shown, a steel plate 14 is preferably fixed on the second angle steel 12.

[0035] like Figure 5 and Figure 6 As shown, the portion of the main cable beam 20 located at the seaside hinge point of the front beam includes a first cable chain groove 21, a second cable chain groove 22, and a third cable chain groove 23 that are rotatably connected in sequence. Here, the second cable chain groove 22 can preferably be a movable cable chain groove.

[0036] Specifically, the structure of the second cable chain groove 22 can preferably be configured such that the first end of the second cable chain groove 22 is connected to the first cable chain groove 21 via a rotating component, and the second cable chain groove 22 is rotatable around the first cable chain groove 21. Here, the rotating component can be a hinge shaft, or other rotating connection component that can realize rotational movement.

[0037] A movable element 24 is provided at the second end of the second cable chain groove 22, and the second cable chain groove 22 moves along the third cable chain groove 23 via the movable element 24. Here, the movable element 24 can preferably be a roller.

[0038] Preferably, the second end of the second cable chain groove 22 is further provided with a sliding connection part 25, one end of the sliding connection part 25 is connected to the bottom end face of the second cable chain groove 22, and the moving part 24 is installed at the other end of the sliding connection part 25.

[0039] like Figure 5 As shown, when the main beam is in a horizontal state, the second cable chain groove 22 slides until the first cable chain groove 21, the second cable chain groove 22, and the third cable chain groove 23 are connected and in a horizontally connected position. Figure 6 As shown, when the main beam is raised, the second drag chain groove 22 moves towards the sea side along the third drag chain groove 23, and the first drag chain groove 21, the second drag chain groove 22 and the third drag chain groove 23 are disconnected from each other.

[0040] The present invention also provides a cable conveying system comprising the articulated boom crane cable chain system described above.

[0041] According to the above structural description, the articulated boom crane cable chain system of the present invention mainly consists of a cable chain bracket and a cable chain main beam. Specifically, at the cable chain bracket, the articulated boom crane cable chain system incorporates diagonal bracing angle steel in the trolley direction, increasing rigidity in that direction, reducing swaying of the cable chain main beam, and extending service life. At the cable chain main beam, a movable second cable chain groove is added. One end of the second cable chain groove is connected via a hinge pin and can rotate around the first cable chain groove. The other end of the second cable chain groove is designed with a rolling wheel. When the front beam is raised, it moves along the cable chain groove towards the sea side, disconnecting the first, second, and third cable chain grooves.

[0042] In summary, the present invention, a folding boom crane cable chain system and a cable conveying system therein, effectively solves the problem of designing the hinge point position of the folding boom crane cable chain main beam by adding diagonal bracing angle steel and movable cable chain groove through structural design of the cable chain main beam and cable chain support.

[0043] The articulated boom crane cable chain system has a simple structure and is easy to operate. It can reduce the swaying of the main cable chain beam, extend its service life, and improve work efficiency.
