Description

Technical Field

[0001] The utility model relates to the technical field of road and bridge construction equipment, in particular to a dredging device for road and bridge construction. Background Art

[0002] During the construction of roads and bridges, it is necessary to cross rivers or tidal flats. These terrains usually have a large amount of silt, which will hinder the construction of roads and bridges. The silt needs to be removed to expose the hard soil layer to meet the support needs of roads and bridges.

[0003] A road and bridge dredging device provided by the publication number CN221095255U includes a moving mechanism, a pumping mechanism and a scraping mechanism. The moving mechanism includes moving wheels, a lifting column is installed on the upper part of the moving wheels, a rotating seat is fixedly connected to the upper end of the lifting column, and a support plate is fixedly connected to the front end of the rotating seat.

[0004] The device drives the movement of the device by applying a thrust to the push handle to drive the rolling of the moving wheels, and adjusts the height of the device by the work of the lifting component to clean the silt at different depths. However, in the silt, the moving wheels and the lifting column are easily trapped in the silt. Due to the blocking and adsorption of the silt, it is difficult to move, and it is difficult to drive the device to move only by pushing the push handle. In the prior art, a crawler is used to drive the movement of the device. In relatively hard silt, even if the crawler is half trapped in the silt, it can still maintain power. However, in relatively soft or muddy silt, the crawler will still be trapped in the silt. At this time, the friction between the silt and the crawler is low, and the device cannot move forward.

[0029] Embodiment 1:

[0030] Please refer to Figures 1-4 , and the above technical solutions of the present invention will be described in detail through the following embodiments:

[0031] A road and bridge construction silt cleaning device includes:

[0032] A silt cleaning assembly 1 for cleaning silt, a moving device 2 is arranged below the silt cleaning assembly 1, and an anti-sinking assembly 3 is arranged below the moving device 2.

[0033] The silt cleaning assembly 1 includes a bucket 11 rotatably installed on the front side of the anti-sinking assembly 3. An auger 13 is rotatably installed inside the bucket 11. A blocking net 12 is welded at the front end opening of the bucket 11. The back of the bucket 11 is connected to a sludge pump 16 through a pipeline.

[0034] On the side of the bucket 11, a first motor 14 is fixedly installed by bolts. The first motor 14 is a well-known submersible motor. The output shaft of the first motor 14 is clamped with the auger 13. When the first motor 14 works, it can drive the auger 13 to rotate, so as to squeeze the silt from both sides to the middle.

[0035] The top of the bucket 11 is rotatably connected with an adjusting oil cylinder 15. When the adjusting oil cylinder 15 works, it can drive the bucket 11 to rotate, so as to control the height of the lower edge of the front end of the bucket 11, and further control the depth of the bucket 11 inserted into the silt.

[0036] The blocking net 12 is used to block large hard impurities in the silt, such as stones, larger branches, etc., from entering the bucket 11.

[0037] The discharge port of the sludge pump 16 is connected to the outside through a pipeline. When the sludge pump 16 works, it can suck out the silt in the bucket 11 through the pipeline and then pump it to the outside through the pipeline.

[0038] The moving device 2 includes a frame 21. A driving device is arranged inside the frame 21. Crawler moving devices are arranged on the left and right sides of the frame 21. The driving device is connected to the crawler moving devices and is used to drive the crawler moving devices to work, so as to drive the device to move.

[0039] The frame 21 is made of welded metal plates and is hollow inside.

[0040] The driving device includes two third motors 22. The output shafts of the two third motors 22 are each self-connected with a transmission shaft 23 through a gear transmission structure. The transmission shaft 23 penetrates through the frame 21 and extends to the outside of the frame 21.

[0041] The third motor 22 can be a servo motor. The two third motors 22 independently control the rotation of a transmission shaft 23. The frame 21 can protect the third motor 22.

[0042] The crawler moving device includes two crawler wheels 24. The front crawler wheel 24 is fixedly connected to the transmission shaft 23. A crawler 26 is wrapped outside the two crawler wheels 24. A support frame 25 is arranged between the two crawler wheels 24. The support frame 25 is fixedly connected to the frame 21.

[0043] The support frame 25 is used to support the middle part of the crawler 26.

[0044] When the third motor 22 works, it can drive the crawler wheel 24 to rotate through the transmission shaft 23, so as to drive the crawler 26 to rotate, and further drive the device to move. By controlling the rotation speed and rotation direction of the two crawlers 26, the moving speed and moving direction of the device can be controlled.

[0045] The anti-sinking component 3 includes a pressure dispersion component which is used to distinguish the pressure of the silt cleaning component 1 and the moving device 2 on the silt to reduce the pressure. Above the pressure dispersion component, there is a floating box 36 which is used to provide buoyancy.

[0046] The floating box 36 is made by blow molding process and is hollow inside.

[0047] The pressure dispersion component includes a uniform pressure plate 31 which is fixedly installed on the bottom surface of the frame 21. The uniform pressure plate 31 is provided with a crawler groove 32 through it. The crawler moving device is located in the crawler groove 32, and the bottom surface of the crawler moving device is lower than the bottom surface of the uniform pressure plate 31.

[0048] The uniform pressure plate 31 can increase the contact area between the device and the silt, so as to reduce the pressure.

[0049] The lower part of the crawler 26 is located below the uniform pressure plate 31, which can facilitate the movement of the device in the silt environment and on the hard bottom surface.

[0050] At the front and rear ends of the uniform pressure plate 31, there are welded approaching inclined plates 33 which are inclined outwards. The floating box 36 is fixedly installed on the top surfaces of the uniform pressure plate 31 and the approaching inclined plates 33 through bolts.

[0051] When the device is moving, the approaching inclined plates 33 can press the silt and hard impurities in the moving direction to the bottom surface of the uniform pressure plate 31 to avoid damage to the device. At the same time, the approaching inclined plates 33 squeeze the silt downwards, which can obtain an upward force and reduce the possibility of the device sinking.

[0052] At the bottom surfaces of the uniform pressure plate 31 and the approaching inclined plates 33, there are welded flow guiding plates 34, and between the flow guiding plates 34 there is a flow guiding groove 35.

[0053] The flow guiding plates 34 and the flow guiding groove 35 can separate the silt.

[0054] In this embodiment, when the operator uses this equipment, the device is placed on the silt surface to be cleaned.

[0055] Control the regulating oil cylinder 15 to work, lower the bucket 11, and make the front lower edge of the bucket 11 insert into the silt.

[0056] Control the first motor 14, the sludge pump 16 and the third motor 22 to work.

[0057] When the third motor 22 works, it drives the crawler wheel 24 to rotate through the transmission shaft 23, thereby driving the crawler 26 to rotate, and further driving the device to move. By controlling the rotation speed and rotation direction of the two crawlers 26, the movement speed and movement direction of the device can be controlled.

[0058] When the device moves, silt will enter the bucket 11 from the front opening of the bucket 11. The blocking net 12 can prevent large hard impurities in the silt, such as stones, larger branches, etc., from entering the bucket 11.

[0059] When the first motor 14 works, it can drive the auger 13 to rotate. The silt that enters the bucket 11 will converge towards the middle of the bucket 11 under the drive of the auger 13.

[0060] When the sludge pump 16 works, it can suck out the silt in the bucket 11 through a pipeline and then pump it to the outside through the pipeline.

[0061] When the device is working, the equalizing plate 31 can increase the contact area between the device and the silt, thereby reducing the pressure and the possibility of the device sinking.

[0062] When the device moves, the approaching inclined plate 33 can press the silt and hard impurities in the moving direction onto the bottom surface of the equalizing plate 31 to avoid damage to the device. At the same time, when the approaching inclined plate 33 presses the silt downward, an upward force can be obtained, which can reduce the possibility of the device sinking.

[0063] The floating box 36 can provide additional buoyancy when the device moves to softer silt or silt mixed with muddy water, to avoid the device sinking too deep.

[0064] The deflector plate 34 and the diversion groove 35 can separate the silt and reduce the adsorption of the silt on the equalizing plate 31 and the approaching inclined plate 33.

[0065] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and do not limit the present invention.
