DETAILED DESCRIPTION

Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0039] The side loading system provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0040] like Figures 1 to 7 As shown, an embodiment of the present application provides a side loading system, including a cargo hold opening and closing assembly and a telescopic load-bearing assembly.

[0041] The cargo hold opening and closing assembly includes a porthole 400, an opening and closing operating cylinder 500, and an upper opening hinge 420 and a lower opening hinge 430 fixedly arranged at the opening position of the cargo hold chamber 140. The upper opening hinge 420 is located at a corresponding position of the cabin roof 180 of the cargo hold chamber 140, and the lower opening hinge 430 is located at a corresponding position of the cabin deck 120 of the cargo hold chamber 140.

[0042] A fixed hinge 170 is fixedly provided on the inner wall of the cargo hold 140 , a driven hinge 410 is fixedly provided on the end surface of the porthole 400 close to the cargo hold 140 , and the fixed end of the opening and closing operating cylinder 500 is hinged to the fixed hinge 170 , and the telescopic end is hinged to the driven hinge 410 .

[0043] The telescopic load-carrying assembly includes a transverse frame 210 located at a corresponding position of the cabin roof 180 and capable of moving laterally, and also includes a power unit for driving the transverse frame 210 to move laterally and a load-carrying unit 600 fixedly arranged on the transverse frame 210. The transverse frame 210 can move laterally until the load-carrying unit 600 is located outside the cargo hold 140.

[0044] The load unit 600 includes an electric winch assembly, a guide wheel assembly, and a steel wire rope 640, one end of which is connected to the electric winch assembly, and the other end of which is passed around the guide wheel assembly and is used to connect the load.

[0045] Among them, the upper hinge 420 is located on the side of the transverse frame 210 away from the cabin deck 120; when the porthole 400 is closed, the two ends of the porthole 400 in the vertical direction are hinged to the upper hinge 420 and the lower hinge 430 respectively; when the porthole 400 is opened upward, the end of the porthole 400 away from the cabin deck 120 is hinged to the upper hinge 420, and when the porthole 400 is opened downward, the end of the porthole 400 away from the cabin top 180 is hinged to the lower hinge 430.

[0046] It is understandable that if Figure 1 As shown, when the two ends of the porthole 400 in the vertical direction are connected to the upper hinge 420 and the lower hinge 430 respectively, the porthole 400 can completely close the opening of the cargo hold 140. At this time, the cargo hold 140 is in a closed state, the transverse frame 210 does not extend to the outside of the cargo hold 140, and cargo can be stored in the cargo hold 140; Figure 5As shown, when the side door 400 is connected to the lower hinge 430 only at the end away from the cabin roof 180, and the end away from the cabin deck 120 is not connected to the upper hinge 420, the telescopic end of the opening and closing operating cylinder 500 can push the side door 400 to flip to the side away from the cargo hold 140 after being extended, and at the same time, the opening and closing operating cylinder 500 adaptively rotates relative to the fixed hinge 170 to adjust the angle. At this time, the side door 400 is in a downward opening state. When the transverse frame 210 is extended to the outside of the cargo hold 140, the side door 400 can be used as a temporary cargo platform, and the load unit 600 is located above the cargo, and the steel wire rope 640 can be retracted and released through the electric winch assembly to realize the lifting and loading and unloading of the cargo; Figure 7 As shown, when the porthole 400 is connected to the upper hinge 420 only at one end away from the cabin deck 120, and the end away from the cabin top 180 is not connected to the lower hinge 430, the telescopic end of the opening and closing operating cylinder 500 is extended to push the porthole 400 to flip to the side away from the cargo hold 140, and the opening and closing operating cylinder 500 adaptively rotates relative to the fixed hinge 170 to adjust the angle. At this time, the porthole 400 is in an upwardly opened state. When the transverse frame 210 is extended to the outside of the cargo hold 140, since the upper hinge 420 is located on the side of the transverse frame 210 away from the cabin deck 120, the porthole 400 will not interfere with the transverse movement of the transverse frame 210, and the water area at the position of the side plate 110 is open. Floating cargo such as small boats move to the bottom of the porthole 400 and close to the side plate 110. The load unit 600 is located above the floating cargo, and the floating cargo can be loaded and unloaded by retracting and releasing the wire rope 640 through the electric winch assembly.

[0047] In an embodiment of the present application, the above-mentioned side loading system is adopted, and the porthole 400 has two working modes when opened: upper opening and lower opening. In the lower opening state, the porthole 400 can be used as a temporary loading platform for cargo. In the upper opening state, an open water space can be provided for floating cargo at the side plate 110. When the transversely movable transverse frame 210 drives the load-carrying unit 600 to move to the corresponding position of the cargo, the cargo can be hoisted by the steel wire rope 640, and the lifting and translation operations of the cargo can be realized by the cooperation of the transverse frame 210 and the electric winch assembly. Compared with the side-swinging and elevator loading and unloading systems, it has the characteristics of simple structure, high reliability and applicability.

[0048] In a preferred embodiment, Figures 1 to 3 , Figures 5 to 7 As shown, the telescopic load-bearing assembly also includes a guide groove 160 arranged at the position of the cabin top 180, and a guide sliding block 220 slidably connected to the guide groove 160 is fixedly provided on the transverse frame 210.

[0049] It can be understood that the power unit can drive the guide slider 220 to slide in the guide groove 160, thereby driving the transverse frame 210 and the load unit 600 to move transversely relative to the cargo compartment 140. At this time, the guide groove 160 can support and guide the transverse movement of the transverse frame 210.

[0050] In a preferred embodiment, Figure 3 , Figure 6 As shown, two guide grooves 160 are provided at the position of the cabin top 180 , and the two guide grooves 160 are respectively located at corresponding positions of two opposite side walls of the cargo compartment 140 .

[0051] It can be understood that the overall lateral movement stability of the lateral movement frame 210 can be improved by the sliding cooperation between the two guide grooves 160 and the guide slider 220 on the lateral movement frame 210 .

[0052] In a preferred embodiment, Figures 1 to 3 , Figure 5 , Figure 7 As shown, the power unit includes a multi-stage electric push rod 300 fixedly arranged on the cabin roof 180 , and the telescopic end of the multi-stage electric push rod 300 is located on the opening side of the cargo compartment 140 and is fixedly connected to the transverse frame 210 .

[0053] When the telescopic end of the multi-stage electric push rod 300 is extended, it can drive the transverse frame 210 to move toward the opening side of the cargo compartment 140, thereby moving the load unit 600 to the outside of the cargo compartment 140 to realize the loading and unloading operations of the cargo.

[0054] It is understandable that the setting form of the power unit is not limited to the above-mentioned one. For example, it can also be set to other transverse movement structures such as gear racks, threaded screws, etc., as long as it can achieve transverse movement drive of the transverse movement frame 210, which will not be elaborated here.

[0055] In a preferred embodiment, the fixed end of the multi-stage electric push rod 300 is hinged to the cabin roof 180 , and the telescopic end is hinged to the transverse frame 210 .

[0056] It can be understood that, through the above-mentioned connection method, when the multi-stage electric push rod 300 drives the transverse frame 210 to move laterally, a greater longitudinal degree of freedom can be provided for the multi-stage electric push rod 300, that is, the multi-stage electric push rod 300 can adaptively deflect the angle to adapt to the height of the connection point with the transverse frame 210, thereby improving its tolerance for the longitudinal position error with the transverse frame 210, and further improving the stability and reliability of the multi-stage electric push rod 300 in driving the transverse frame 210 laterally.

[0057] In a preferred embodiment, Figures 3 to 7As shown, the load unit 600 also includes a mounting frame 610 fixedly disposed on the transverse frame 210 , and the electric winch assembly includes a winding motor 620 fixedly connected to the mounting frame 610 , and a winch wheel 630 fixedly connected to the output end of the winding motor 620 .

[0058] The steel wire rope 640 is wound on the winch wheel 630 .

[0059] It is understandable that when the winding motor 620 drives the capstan 630 to rotate, the wire rope 640 on the capstan 630 can be tightened or loosened, thereby achieving lifting and lowering control of the end of the wire rope 640 away from the capstan 630 connected to the load.

[0060] In a preferred embodiment, Figures 3 to 7 As shown, the guide wheel assembly includes a first guide wheel 650 and a second guide wheel 660 rotatably disposed on the mounting frame 610 .

[0061] Among them, the rotation axis of the first guide wheel 650 is located in the vertical direction, and the rotation axis of the second guide wheel 660 is located in the horizontal direction. The end of the wire rope 640 away from the winch 630 passes around the first guide wheel 650 and the second guide wheel 660 in turn and is used to connect the load.

[0062] It is understandable that the setting form of the guide wheel assembly is not limited to the above-mentioned one, as long as it can guide the wire rope 640, which will not be elaborated here.

[0063] In a preferred embodiment, Figures 3 to 7 As shown, two winding parts are axially provided on the winch 630, and steel wire ropes 640 are respectively wound on the two winding parts.

[0064] Two groups of first guide wheels 650 and second guide wheels 660 are symmetrically arranged on the mounting frame 610 about the first reference plane, and the wire ropes 640 on the two winding parts are respectively passed around the two groups of first guide wheels 650 and second guide wheels 660.

[0065] Among them, the axial direction of the winch 630 is parallel to the lateral direction of the lateral frame 210, the first reference plane is specifically set as the axial vertical plane of the winch 630 at the connection position of the two winding parts, and the second guide wheel 660 is located on the side of the first guide wheel 650 of the corresponding group away from the first reference plane.

[0066] It can be understood that the winding of the two steel ropes 640 can be controlled simultaneously by the winch 630. When the two steel ropes 640 are respectively led out from the two second guide wheels 660, the cargo can be connected at two points, thereby improving the loading and unloading stability of the cargo.

[0067] In a preferred embodiment, Figure 3 , Figure 6As shown, two groups of load carrying units 600 are symmetrically arranged on the transverse frame 210 with respect to the second reference plane.

[0068] The second reference plane is specifically set to be a bisecting plane between two opposite side walls of the cargo compartment 140 .

[0069] It should be noted that the side walls of the cargo hold chamber 140 refer to the inner walls on both sides in the front-to-back direction as shown in the figure, and the bisecting plane refers to a plane located between two planes (i.e., two opposite side walls of the cargo hold chamber 140) and at the same distance from the two planes.

[0070] It can be understood that since the winch 630 of a load unit 600 can control the winding of two steel ropes 640 at the same time, the two groups of load units 600 can achieve connection to the four corners of the cargo through four steel ropes 640, further improving the connection reliability and loading and unloading stability of the cargo. At the same time, the four lifting points of the two groups of load units 600 can also be operated independently, which is more adaptable to the cargo and further improves the practicality of the loading system.

[0071] In a preferred embodiment, Figure 3 , Figure 6 As shown, the transverse frame 210 is provided with a connecting beam 230 which is perpendicular to two opposite side walls of the cargo compartment 140 , and the mounting frame 610 is fixedly disposed on the connecting beam 230 .

[0072] In a preferred embodiment, Figure 1 , Figure 3 , Figures 5 to 7 As shown, it also includes a working compartment 130 separated from the cargo compartment 140 by a partition longitudinal wall 150.

[0073] When the transverse moving frame 210 does not extend out of the cargo compartment 140 , a portion of the transverse moving frame 210 is located at a position corresponding to the cabin roof 180 of the working compartment 130 .

[0074] It should be noted that, in this article, the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise one..." do not exclude the presence of other identical elements in the process, method, article or device including the element. In addition, it should be pointed out that the scope of the methods and devices in the embodiments of the present application is not limited to performing functions in the order shown or discussed, and may also include performing functions in a substantially simultaneous manner or in reverse order according to the functions involved, for example, the described method may be performed in an order different from that described, and various steps may also be added, omitted, or combined. In addition, the features described with reference to certain examples may be combined in other examples.

[0075] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
