Description

Technical Field

[0001] The utility model relates to the technical field of dredging equipment, in particular to a mobile river channel dredging equipment. Background Art

[0002] During the operation of the river, due to the silt carried by the water flow or soil erosion on the slope, it is easy to cause silt accumulation in the riverbed, raising the height of the riverbed and causing the water level to rise. Therefore, regular dredging is required. At this stage, the most commonly used mobile dredging method is the chain bucket dredging ship, which uses a chain to drive the bucket to circulate, dig out the silt in the river channel, and then transport it for treatment through mud traps and mud barges.

[0003] In the above process, the chain bucket dredging equipment required for existing mobile dredging needs to cooperate with the swing of the hull to achieve the change of excavation direction. However, if the ship wants to fully control the course in the water, it needs to use the continuous raising and lowering of the anchor, so it is more laborious during the operation. In view of this, in-depth research was conducted on the above issues, and this case came into being. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 The utility model provides an implementation scheme: in modern river channel dredging equipment, in order to expand the cleaning range of the river channel and dredge the river channel close to the center of the river at the same time, a chain bucket dredging device mounted on a hull is often used. However, the existing chain bucket dredging equipment is arranged relatively close to the middle section of the hull. During the operation of the device, the hull needs to swing left and right to expand the dredging range. However, the movement of the ship in the river channel is restricted by the water depth, etc. On the one hand, it is inconvenient to move, and on the other hand, this method wastes energy.

[0022] In view of the above technical problems, the present application discloses a mobile river channel dredging equipment, which is connected to the rear of a ship body through a support plate 1, the support plate 1 is a rectangular plate, a pair of sliding rails 2 are symmetrically arranged on the support plate 1, a pair of sliding plates are arranged on the pair of sliding rails 2, an adjustment block 3 is mounted on the pair of sliding plates, a bucket bridge 4 is arranged on the adjustment block 3, and a plurality of dredging buckets 5 connected by a chain structure are mounted on the bucket bridge 4. In a specific implementation process, by adjusting the adjustment block 3 to move the sliding plate on the sliding rail 2, the adjustment block 3 can drive the head end of the bucket bridge 4 to completely extend out of the ship body;

[0023] Furthermore, a rotating disk 6 is provided on the adjusting block 3, and the rotating disk 6 and the adjusting block 3 are movably connected by an axle seat 7. A rotating gear 8 is sleeved on the bottom axle seat 7 of the rotating disk 6, and a swinging assembly 12 is provided on the adjusting block 3 to mesh with the rotating gear 8. In the specific implementation process, the swinging assembly 12 can drive the rotating gear 8 to swing and rotate, so that the axle seat 7 drives the rotating disk 6 to swing, and then the direction of the bucket bridge 4 is changed, thereby expanding the range of dredging without moving the hull;

[0024] Furthermore, a rotating shaft 9 is provided at the bottom end of the middle section of the bucket bridge 4, a pair of position-limiting rotating seats 10 are symmetrically provided on the rotating disk 6, the rotating shaft 9 is assembled on the pair of position-limiting rotating seats 10, a pair of adjusting cylinders 11 are provided on the rotating disk 6, and the telescopic ends of the pair of adjusting cylinders 11 are movably connected to the two sides of the bucket bridge 4;

[0025] During the specific implementation process, the rotating shaft 9 of the bucket bridge 4 is limited and installed by a pair of limiting swivel seats 10 on the rotating disk 6, and the bucket bridge 4 is pushed to change its posture by a pair of adjusting cylinders 11, thereby adjusting the pitch angle of the bucket bridge 4, and making the bottom end of the bucket bridge 4 contact the silt on the riverbed according to the working requirements.

[0026] Furthermore, a linear screw module 13 is provided on the support plate 1 and is arranged parallel to a pair of sliding rails 2 and between the two. The movable end of the linear screw module 13 is connected to the adjustment block 3. The linear screw module 13 can drive the sliding plate on the adjustment block 3 and the sliding rail 2 to move relative to each other, thereby changing the position of the adjustment block 3.

[0027] Furthermore, the bucket bridge 4 is a supporting rectangular frame formed by welding pipe fittings, and the rotating shaft 9 is located on the bottom surface of the bucket bridge 4 .

[0028] Furthermore, a pair of limiting rods 14 are symmetrically arranged on both sides of the rotating disk 6 on the adjusting block 3 to limit the rotation angle of the bucket bridge 4.

[0029] Furthermore, the swing assembly 12 includes a secondary reduction gear 121, which is arranged on one side of the rotating gear 8, and a driving worm gear 122 is coaxially arranged on the secondary reduction gear 121. An adjusting motor 123 is provided on the adjusting block 3, and an adjusting worm 124 is connected to the driving end of the adjusting motor 123, and the adjusting worm 124 is meshed with the driving worm gear 122;

[0030] During the specific implementation process, the adjusting motor 123 is used to drive the adjusting worm 124 to rotate, so that the adjusting worm 124 is meshed with the driving worm wheel 122, and the driving worm wheel 122 drives the coaxial secondary reduction gear 121 to rotate, so that the secondary reduction gear 121 is meshed with the rotating gear 8, so that the rotating gear 8 drives the shaft seat 7 to rotate. Since the number of teeth of the secondary reduction gear 121 and the rotating gear 8 is relatively small, and there are driving worms and driving worm wheels 122 to reduce speed, on the one hand, the rotation angle of the shaft seat 7 will change very little, which is convenient for the reverse swing of the driving motor. On the other hand, the power demand for the driving motor is reduced. On one side of the shaft seat 7, an encoder 125 for detecting the rotation angle of the shaft seat 7 is connected through a coupling for accurately detecting the rotation angle of the shaft seat 7.

[0031] From the above, it can be generally known that the mobile river dredging equipment moves the bucket bridge 4 of the traditional chain bucket dredger from the middle of the ship to the stern, and a rotating disk 6 driven by a swing assembly 12 is provided on the bucket bridge 4, which can adjust the orientation of the bucket bridge 4. Therefore, there is no need to adjust the posture of the hull. This saves operation and can conveniently control the position of the bucket bridge 4 without frequently swinging the hull, and can expand the operating range of the equipment.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
