[0024] The following is combined with Figure 1-3 The utility model is described in further detail.

[0025] The utility model embodiment discloses a crane for river cleaning, referring to Figure 1 , including a crane body 1, a telescopic arm installed on one side of the crane body 1, an electric grab 3 installed at the end of the telescopic arm and used to grab garbage in the river, and a control mechanism installed on the crane body 1. The crane body 1 is an existing port crane. The crane body 1 adopts a steel structure and is installed on the shore or a mobile platform. It has stable support and lifting capabilities. The electric grab 3 installed at the end of the telescopic arm has an opening and closing function and can grab garbage in the river.

[0026] Reference Figure 1The end of the telescopic arm is connected to the electric grab 3 by a wire rope, and the end of the wire rope is connected to the winch of the crane body 1. The crane body 1 can lift or lower the electric grab 3 by winding or extending the wire rope by the winch. The wire rope, winch and other components are common components of existing cranes, and their connection and principles have been disclosed, so they will not be elaborated here.

[0027] Reference Figure 1-2 The telescopic arm includes a fixed arm 2 which is fixed and inclined on one side of the crane body 1, a movable arm 21 which is slidably arranged in the fixed arm 2, and a first hydraulic cylinder 22 which is fixedly installed between the bottom end of the movable arm 21 and the inner bottom of the fixed arm 2. The first hydraulic cylinder 22 can be an electric hydraulic cylinder. The fixed arm 2 can support and limit the movable arm 21. After the first hydraulic cylinder 22 is extended or retracted, it will drive the movable arm 21 to move up and down on the fixed arm 2, thereby realizing the extension and retraction of the telescopic arm.

[0028] Reference Figure 1 The control mechanism includes a PLC control cabinet 4 fixed on the outer wall of the crane body 1 for controlling the extension and retraction of the first hydraulic cylinder 22 and the opening and closing of the electric grab 3. The PLC control cabinet 4 can realize precise control of the telescopic arm and the electric grab 3 according to programming and other settings to improve the cleaning efficiency. The PLC control cabinet 4 and the electric grab 3 are common components of existing cranes, and their internal connections have been disclosed and will not be repeated here.

[0029] Reference Figure 1 A cleaning system for quickly cleaning up the grabbed garbage is provided on one side of the crane body 1. The cleaning system includes a garbage collection mechanism provided on one side of the crane body 1 for collecting the garbage grabbed by the crane, a garbage disposal mechanism provided on one side of the crane body 1 for processing the collected garbage, and a transportation mechanism provided on one side of the crane body 1 for transporting the processed garbage to a designated location, thereby realizing systematic and rapid processing of the garbage grabbed by the crane and improving efficiency.

[0030] Reference Figure 1 and Figure 3 A bottom plate 11 is fixedly provided at the bottom of the crane body 1, and the garbage collection mechanism includes a garbage collection pool 5 fixedly provided on the top of the bottom plate 11. The bottom plate 11 can support and fix the crane body 1 and the garbage collection pool 5 and other components. The crane body 1 can grab the garbage in the river through the electric grab 3 and transport it to the top of the garbage collection pool 5, and then control the opening and closing of the electric grab 3 so that the grabbed garbage can be put down and fall into the garbage collection pool 5.

[0031] Reference Figure 1 and Figure 3The garbage disposal mechanism includes a second hydraulic cylinder 6 fixedly arranged on the inner side of the garbage collection pool 5, and a pressure plate 61 fixedly arranged at the telescopic end of the second hydraulic cylinder 6 for compressing the garbage in the garbage collection pool 5. The pressure plate 61 is slidably connected in the garbage collection pool 5. The second hydraulic cylinder 6 can be a multi-stage hydraulic cylinder. After the second hydraulic cylinder 6 is telescoped, it will drive the pressure plate 61 to move horizontally. After the pressure plate 61 moves, it can first push the garbage in the garbage collection pool 5 to gather, and then compress the gathered garbage.

[0032] Reference Figure 1 and Figure 3 A triangular prism 62 is fixedly provided on the top of the pressure plate 61 for limiting the compressed garbage and guiding the garbage dropped by the electric grab 3. The triangular prism 62 can cover the top of the garbage when compressing the garbage, making the garbage more concentrated and convenient for compression. When the electric grab 3 drops the garbage, some of the fallen garbage is guided by the inclined surface of the top of the triangular prism 62 and is more likely to enter the compression area in the garbage collection pool 5 under the influence of gravity.

[0033] Reference Figure 1 and Figure 3 A plurality of drain pipes 51 are fixedly provided at the bottom of one end of the garbage collection pool 5 away from the second hydraulic cylinder 6, and a filter plate 52 is fixedly installed on the inner wall of the top end of the drain pipe 51. The drain pipe 51 can discharge the water flowing down when the garbage in the garbage collection pool 5 is compressed, and the filter plate 52 can block the garbage, so that the garbage is not easy to enter the drain pipe 51 during compression and block the drain pipe 51.

[0034] Reference Figure 1 and Figure 3 The transport mechanism includes a transport vehicle 7 that cooperates with and abuts against the top of the bottom plate 11. After the garbage is compressed, the crane can transfer the compressed garbage to the transport vehicle 7 through the electric grab 3, and the transport vehicle 7 transports the processed garbage to a designated location.

[0035] The implementation principle of a crane for river cleaning in the embodiment of the utility model is:

[0036] When in use, the crane body 1 can realize precise control of the telescopic arm and the electric grab 3 through the PLC control cabinet 4. The electric grab 3 can grab the garbage in the river after opening and closing, so as to clean the river. After the first hydraulic cylinder 22 is extended and retracted, it will drive the movable arm 21 to move up and down on the fixed arm 2, so as to realize the extension and retraction of the telescopic arm. By adjusting the length of the telescopic arm, the crane can grab the garbage in the river at different distances, so as to meet the cleaning needs in different river distance environments;

[0037] Next, the crane body 1 can grab the garbage in the river through the electric grab 3 and transfer it to the top of the garbage collection pool 5, and then control the opening and closing of the electric grab 3 so that the grabbed garbage can be put down and fall into the garbage collection pool 5. At this time, the fallen garbage is guided by the top inclined surface of the triangular prism 62 and is more likely to enter the compression area in the garbage collection pool 5 with gravity;

[0038] Then the second hydraulic cylinder 6 is controlled to extend and retract to drive the pressing plate 61 to move horizontally. After the pressing plate 61 moves, it can first push and gather the garbage in the garbage collection pool 5, and cooperate with the triangular prism 62 to block and limit the garbage to compress the gathered garbage;

[0039] After the garbage is compressed, the crane can transfer the compressed garbage to the transport vehicle 7 through the electric grab 3, and the transport vehicle 7 transports the processed garbage to a designated location to systematically and quickly clean up the grabbed garbage.

[0040] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
