Description

Technical Field

[0001] The present invention relates to river cleaning, and particularly to a river dredging device. Background Art

[0002] In river cleaning, the cleaning of river bottom silt is also a very important step. For the cleaning of silt, there are generally: dry cleaning, that is, first pumping out the water in the river, and then cleaning the silt by excavators, manual labor, etc. Although this method has good effects, it has a large workload and also has a great impact on the ecological environment of the entire river; wet cleaning, generally by boats, carrying an excavator on the boat or setting a sewage suction device for sucking silt on a steamship, and directly driving the boat into the river for dredging operations. This method is convenient to operate and has little impact on the ecological environment of the river.

[0003] However, for wet cleaning, the volume of general boats is relatively large and is not suitable for narrow rivers, especially for small rivers in some rural areas, and the dry cleaning method is still used. Summary of the Invention

[0014] With the above technical solution, during use, the moving mounting frame is driven to extend through the scissors lift, and the second moving and mounting part is guided by the guide rail and the second support rollers. The two first motors cooperate with the steel wire rope to drive the second moving and mounting part to move back and forth; in cooperation with the driving of the sewage suction vehicle, the position of the sludge suction can be adjusted well. When not in use, the moving mounting frame is driven to retract through the scissors lift, and the second moving and mounting part is supported only by the second support rollers, and the first steel wire rope is also wound up, and the guide rail is placed on the sewage suction vehicle.

[0015] Further, the second support roller includes a first support part and a second support part. The second moving and mounting part cooperates with the first support part, and the second support part is used to support the guide rail.

[0041] Please refer to Figure 1 , Figure 2 and Figure 3 , a river dredging device, comprising: a sewage suction truck 1, a fixed mounting bracket 2, a movable mounting bracket 3, two groups of scissor lifts 4, a hydraulic cylinder 5, two guide rails 6, a first movable mounting part 7, a second movable mounting part 8, a third movable mounting part 9, a driving mechanism, two first motors 10, a first steel wire rope 11, and a fixed pulley 12.

[0042] The sewage suction truck 1 is a prior art. Through the sewage suction pipe 1B, sludge can be sucked into the storage tank of the sewage suction truck 1. The sewage suction truck 1 is also equipped with a hose reel 1A, which is a prior art, connected to the storage tank, and can wind and release the sewage suction pipe 1B.

[0043] The fixed mounting bracket 2 is fixedly connected to the sewage suction truck 1. Two sets of scissor frames 4 are arranged between the fixed mounting bracket 2 and the movable mounting bracket 3 and can be telescopically extended and retracted horizontally. For the convenience of description, the hinge points on the scissor frame 4 are sequentially divided into top hinge points 4A, middle hinge points 4B, and bottom hinge points. Second support rollers 13 are arranged inwardly at the top hinge points 4A of the two sets of scissor frames 4.

[0044] The hydraulic cylinder 5 is arranged between the fixed mounting bracket 2 and the scissor frame 4 and is used to drive the movable mounting bracket 3 to telescopically extend and retract horizontally. Specifically, the cylinder body of the hydraulic cylinder 5 is hinged to the fixed mounting bracket 2. A first connecting rod 4D is arranged between the outer bottom hinge points of the two sets of scissor frames 4 close to the fixed mounting bracket 2, and the telescopic rod of the hydraulic cylinder 5 is hinged to the first connecting rod 4D.

[0045] Please refer to Figure 5 , grooves 8A for cooperating with the second support rollers 13 are arranged on both sides of the second movable mounting part 8. In this way, when the two sets of scissor frames 4 are in a retracted state, the distance between the second support rollers 13 is very small, and multiple second support rollers 13 can be accommodated in the grooves 8A at the same time. Only relying on the two rows of second support rollers 13, the support and limit of the second movable mounting part 8 can be completed.

[0046] Please refer to Figure 7 , optionally, when the scissor frame 4 is retracted, the fixed mounting bracket 2 and the movable mounting bracket 3 respectively abut against both sides of the second movable mounting part 8. In this way, when the scissor frame 4 is retracted, the second movable mounting part 8 remains stable, and the whole sewage suction truck 1 is not prone to shaking during driving.

[0047] Please refer to Figure 3 and Figure 10 , during the telescopic process of the scissor frame 4, the two rows of second support rollers 13 do not move up and down, and the height remains unchanged. That is, for each set of scissor frames 4, the top hinge points 4A on the left and right sides are respectively hinged to the fixed mounting bracket 2 and the movable mounting bracket 3, and first sliders 4E are hinged to the bottom hinge points 4C on the left and right sides. These first sliders 4E are respectively slidably connected to the fixed mounting bracket 2 and the movable mounting bracket 3 up and down.

[0048] Both ends of the two guide rails 6 are detachably and fixedly connected to the fixed mounting bracket 2 and the movable mounting bracket 3 respectively. The first movable mounting portion 7 is slidably connected to the two guide rails 6, and the second movable mounting portion 8 is also detachably and fixedly connected to the first movable mounting portion 7. Specifically, the two guide rails 6 can adopt the first linear guide rail 6, and the first mounting block that matches the first linear guide rail 6 is the first movable mounting portion 7.

[0049] After the two sets of scissor frames 4 are extended, the distance between the second support rollers 13 increases. Relying only on the two rows of second support rollers 13 cannot meet the support and limitation of the second movable mounting portion 8, and subsequent movement of the second movable mounting portion 8 along the two rows of second support rollers 13. Therefore, before the two sets of scissor frames 4 are extended:

[0050] S1. First, fixedly connect one end of the two guide rails 6 to the movable mounting bracket 3;

[0051] S2. Then adjust the position of the first movable mounting portion 7 and fixedly connect the second movable mounting portion 8 to the first movable mounting portion 7;

[0052] S3. Then extend the two sets of scissor frames 4 to pull out the two guide rails 6;

[0053] S4. Finally, fixedly connect the other ends of the two guide rails 6 to the fixed mounting bracket 2.

[0054] Please refer to Figure 9 , optionally, the second support roller 13 includes a first support portion 13-1 on the inner side and a second support portion 13-2 on the outer side. The second movable mounting portion 8 cooperates with the first support portion 13-1, and the second support portion 13-2 is used to support the guide rail 6. In this way, after the two guide rails 6 are erected between the fixed mounting bracket 2 and the movable mounting bracket 3, the middle parts are also respectively supported by the two rows of second support rollers 13, making it more stable.

[0055] Optionally, the second support portion 13-2 is provided with a limiting groove 13-2A that matches the bottom of the guide rail 6. In this way, through the limiting groove 13-2A, the two guide rails 6 can be more conveniently fitted to each second support roller 13.

[0056] Please refer to Figure 1 and Figure 6, the third moving mounting part 9 is used to fix the pipe orifice of the sewage suction pipe 1B and is slidably connected to the second mounting part up and down. Specifically, a plurality of telescopic bars 14 are arranged between the third moving mounting part 9 and the second mounting part. The driving mechanism is arranged on the second moving mounting part 8 and is used to drive the third moving mounting part 9 to slide. Specifically, a second motor 15 with a brake is arranged on the second moving mounting part 8 (a rechargeable power source for supplying power to the second motor 15 can also be arranged on the second moving mounting part 8). A second steel wire rope is arranged between the winding roller of the second motor 15 and the third moving mounting part 9 (the second steel wire rope is not shown in the drawings for the convenience of representation).

[0057] Please refer to Figure 4 , Figure 8 and Figure 9 , both first motors 10 are arranged on the fixed mounting frame 2, and the fixed pulley 12 is arranged on the moving mounting frame 3. Both ends of the first steel wire rope 11 are respectively arranged on the winding rollers of the two first motors 10, and the middle part passes through the fixed pulley 12. One side of the first steel wire rope 11 is also detachably and fixedly connected to the second moving mounting part 8. Specifically, a plurality of Ω-shaped clips 16 are arranged on the second moving mounting part 8 and are connected to the second moving mounting part 8 through screws on both sides. By tightening the screws on both sides, the first steel wire rope 11 can be clamped and fixed to the second moving mounting part 8.

[0058] In the above S3 step, first release the brake of one of the first motors 10. When the two sets of scissor frames 4 extend, while bringing out the two guide rails 6, they also bring out the first steel wire rope 11. After the above S4 step, fix one side of the first steel wire rope 11 to the second moving mounting part 8. In this way, for the two first motors 10, release the brake of one of the first motors 10, and the other first motor 10 winds the first steel wire rope 11, then the second moving mounting part 8 and the third moving mounting part 9 can be driven to move towards the moving mounting frame 3. By swapping the operations of the two motors, the second moving mounting part 8 and the third moving mounting part 9 can be driven to move towards the fixed mounting frame 2.

[0059] Briefly describe the working principle of the present utility model:

[0060] The sewage suction truck 1 drives to one side bank of the river channel, and the moving mounting frame 3 is extended to the other side bank through the scissor frame 4; when the moving mounting frame 3 extends, it also brings out the guide rails 6, completes the erection of the guide rails 6 between the moving mounting frame 3 and the fixed mounting frame 2, and connects the second moving mounting part 8 and the first moving mounting part 7; when the moving mounting frame 3 extends, it also brings out the first steel wire rope 11 and connects the first steel wire rope 11 and the second moving mounting part 8. In this way, the driving mechanism drives the pipe orifice of the sewage suction pipe 1B to sink into the river channel and suck out the silt at the river bottom; the sewage suction truck 1 moves along the bank, and in cooperation with the movement of the second moving mounting part 8 between the fixed mounting frame 2 and the moving mounting frame 3, the position of sucking silt can be conveniently adjusted.

[0061] After sucking up the silt, the third moving and installing part 9 moves upward to reset, and the second moving and installing part 8 moves toward the fixed mounting bracket 2 to reset. The connection between the two guide rails 6 and the fixed mounting bracket 2 is released, and the moving mounting bracket 3 moves toward the fixed mounting bracket 2 to reset. The hydraulic cylinder 5 can drive the two sets of scissor frames 4 to retract, thereby driving the moving mounting bracket 3 to move toward the fixed mounting bracket 2. However, in this process, the first steel wire rope 11 also needs to be retracted, and the synchronization between the two is not easy to control. Although it can be gradually retracted, the operation is not convenient.

[0062] Please refer to Figure 10 , optionally, the hydraulic cylinder 5 and the first connecting rod 4D are detachably hinged. Specifically, a Ω-shaped first connecting piece 17 is fixedly connected to the telescopic rod of the hydraulic cylinder 5, and a Ω-shaped second connecting piece 18 is detachably connected to the first connecting piece 17. In this way, for the step of "the moving mounting bracket 3 moves toward the fixed mounting bracket 2 to reset", the connection between the hydraulic cylinder 5 and the first connecting rod 4D can be released, the brake of one of the first motors 10 is locked, and the other first motor 10 winds up the first steel wire rope 11 to drive the moving mounting bracket 3 to move toward the fixed mounting bracket 2.

[0063] Please refer to Figure 5 , optionally, both ends of the groove 8A are inclined. In this way, during the movement of the second moving and installing part 8, the second support roller 13 can more easily enter the groove 8A of the second moving and installing part 8.

[0064] Please refer to Figure 1 and Figure 6 , optionally, a vertically telescopic first support roller 19 is provided on the moving mounting bracket 3. Specifically, support arms 20 are provided on both sides of the moving mounting bracket 3, the first support roller 19 is rotatably connected to the lower end of the support arm 20, and bolt and nut fasteners are provided between the support arm 20 and the moving mounting bracket 3. By loosening the bolt, the support arm 20 can be moved up and down, and by tightening the bolt, the support arm 20 can be fixed to the moving mounting bracket 3. In this way, after the moving mounting bracket 3 extends out, the support arm 20 can be extended downward to make the first support roller 19 touch the ground, so that the entire dredging device moves more stably along the riverbank, and the movement of the second moving and installing part 8 on the guide rail 6 is also more stable.
