Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of river dredging, in particular to a river chain bucket dredging ship. BACKGROUND

[0002] River dredging generally refers to river regulation and belongs to water conservancy projects. Through mechanical equipment, the silt deposited at the river bottom is stirred into turbid water and flows away with the river water, thereby playing a dredging role.

[0003] The smoothness of the river directly affects the local flood discharge and flood control capacity, especially during the flood season. At present, the main methods for river dredging on the market are manual excavation and traditional ship excavation. Common excavation ships include chain bucket dredging ships. During use, due to the continuous rotation of the bucket chain and the collision of the bucket with the soil, a large amount of noise and vibration is generated, which not only affects the health and work efficiency of the operators, but also may cause noise pollution to the surrounding environment. CONTENT OF THE INVENTION

[0004] In view of the deficiencies of the prior art, the present application provides a river chain bucket dredging ship, which has the advantages of reducing noise and vibration, and solves the problems raised in the background art.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical scheme: a river chain bucket dredging ship, comprising a ship body, a bucket bridge is installed at the left end of the ship body, two transmission rollers are rotationally connected to the inner wall of the bucket bridge, two bucket chains are transmissionally connected to the outer surfaces of the two transmission rollers, a plurality of excavators are hingedly connected between the two bucket chains and are distributed at equal distances, a support frame is arranged at the low end of each excavator, a contact rod is rotationally connected to the inner wall of each support frame, each support frame is slidingly inserted into the excavator close to it at the upper end, two first springs are fixedly connected to the upper surface of each support frame, the other end of each first spring is fixedly connected to the excavator close to it, a plurality of buffer cylinders are arranged above the bucket bridge, a sliding piece is slidingly connected to the inside of each buffer cylinder, a first steel cable is fixedly connected to the upper end of each sliding piece, the other end of each first steel cable is fixedly connected to the excavator close to it, a second steel cable is fixedly connected to the low end of each buffer cylinder, and the other end of each second steel cable is fixedly connected to the bucket chain close to it.

[0006] Through the above-mentioned scheme, the vibration generated when the excavator contacts the bucket bridge can be reduced by installing the first spring and the contact rod in cooperation, so that the excavator can maintain a stable state.

[0007] Further, a second spring is fixedly connected to the inner wall of each buffer cylinder, and the other end of each second spring is fixedly connected to the sliding piece close to it.

[0008] Through the above scheme, the installation of the second spring can drive the sliding reset through the deformation force of the second spring, and can buffer the swing force when the excavator bucket swings, so that the excavator bucket can stably swing.

[0009] Further, the inner wall of the bucket bridge is slidingly inserted with a plurality of sliding buffers, the outer surfaces of the plurality of sliding buffers are fixedly connected with elastic members, and the other ends of the plurality of elastic members are fixedly connected with the bucket bridge.

[0010] Through the above scheme, the cooperation of the sliding buffer and the elastic member can make the flexible contact between the contact rods and the sliding buffer, and can avoid generating large noise.

[0011] Further, the two transmission rollers are drivingly connected through a chain wheel and a chain.

[0012] Through the above scheme, the transmission between the two transmission rollers through the chain can stably output power, so that the two transmission rollers can synchronously rotate.

[0013] Further, the plurality of contact rods are made of rubber material.

[0014] Through the above scheme, the contact rod made of rubber material can avoid the collision between the excavator bucket and the bucket bridge under the condition that the excavator bucket is heavy, and can avoid generating large noise and unstable condition, thereby improving the stability of the excavator bucket.

[0015] Further, the upper surfaces of the plurality of sliding buffers are made of rubber material.

[0016] Through the above scheme, the upper surface of the sliding buffer made of rubber material can improve the overall buffering capacity of the excavator, thereby avoiding the instability of the excavator due to rigid contact.

[0017] Further, the upper ends of the plurality of buffer cylinders are provided with sealing rings, and the plurality of sealing rings are in contact with the first steel cables adjacent thereto.

[0018] Through the above scheme, the installation of the sealing ring can seal the buffer cylinder, so that the buffer cylinder can maintain a sealed state, and the pressure in the buffer cylinder can be kept balanced.

[0019] Further, the plurality of first springs and the plurality of elastic members are subjected to anti-rust and anti-corrosion treatment.

[0020] Through the above scheme, the anti-corrosion treatment of the first spring and the elastic member can improve the anti-corrosion property of both, and avoid the corrosion of water to cause the decrease of elastic force.

[0021] Compared with the prior art, the technical scheme of the present application has the following beneficial effects:

[0022] This type of river dredging vessel uses a first spring and a contact rod to reduce vibrations when the bucket contacts the bucket bridge, thus maintaining the bucket's stability. The use of a buffer cylinder and a sliding component reduces noise during bucket tilting, further ensuring bucket stability. This reduces noise and vibration transmitted by the bucket during operation, enabling stable dredging operations. Attached Figure Description

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] Please see Figure 1 , Figure 2 and Figure 3This embodiment of a river dredging vessel includes a hull 1. A bucket bridge 2 is installed at the left end of the hull 1. Two drive rollers 3 are rotatably connected to the inner wall of the bucket bridge 2. Two bucket chains 4 are drively connected to the outer surfaces of the two drive rollers 3. Multiple buckets 5 are hinged between the two bucket chains 4 and are distributed at equal intervals. Each bucket 5 has a support frame 6 at its lower end. Each support frame 6 has a contact rod 7 rotatably connected to its inner wall. The upper ends of each support frame 6 are slidably inserted into the buckets 5 adjacent to them. Two first springs 8 are fixedly connected to the upper surfaces of each support frame 6. The other ends of each first spring 8 are fixedly connected to the buckets 5 adjacent to them. Multiple buffer cylinders 9 are provided above the bucket bridge 2. The interiors of the multiple buffer cylinders 9 are slidably connected. A sliding member 10 is attached, and the upper end of each sliding member 10 is fixedly connected to a first steel cable 11. The other end of each first steel cable 11 is fixedly connected to a bucket 5 adjacent to it. The lower end of each buffer cylinder 9 is fixedly connected to a second steel cable 12. The other end of each second steel cable 12 is fixedly connected to a bucket chain 4 adjacent to it. By installing the first spring 8 and the contact rod 7, the vibration generated when the bucket 5 contacts the bucket bridge 2 can be reduced, so that the bucket 5 can maintain a stable state. By installing the buffer cylinder 9 and the sliding member 10, the abnormal noise emitted by the bucket 5 when it is overturned can be reduced, so that the bucket 5 can maintain stability. The noise and vibration transmitted by the bucket 5 during operation can be reduced, so that the dredging work can be carried out stably.

[0031] Please see Figure 1 , Figure 2 and Figure 3 Multiple buffer cylinders 9 have second springs 13 fixedly connected to their inner walls. The other ends of the multiple second springs 13 are fixedly connected to the adjacent sliding parts 10. The installation of the second springs 13 can drive the sliding weight reduction to reset through the deformation force of the second springs 13, and at the same time can buffer the swing force when the bucket 5 swings, so that the bucket 5 can swing stably. Multiple sliding buffer parts 14 are slidably inserted into the inner wall of the bucket bridge 2. Elastic parts 15 are fixedly connected to the outer surface of the multiple sliding buffer parts 14. The other ends of the multiple elastic parts 15 are fixedly connected to the bucket bridge 2. The installation of sliding buffer parts... The cooperation between the punch 14 and the elastic element 15 enables flexible contact between the contact rod 7 and the sliding buffer 14, while avoiding excessive noise. The two drive rollers 3 are connected by a sprocket and a chain drive, which enables stable power output and allows the two drive rollers 3 to rotate synchronously. The upper surfaces of the multiple sliding buffers 14 are all made of rubber. The rubber material on the upper surfaces of the sliding buffers 14 improves the overall buffering capacity of the bucket 5, thereby preventing instability of the bucket 5 due to rigid contact.

[0032] Please see Figure 1 , Figure 2 and Figure 4Multiple contact rods 7 are made of rubber. The rubber material of the contact rods 7 can prevent the bucket 5 from colliding with the bucket bridge 2 when it is heavy, thus avoiding the generation of large noise and instability, thereby improving the stability of the bucket 5. Multiple buffer cylinders 9 are equipped with sealing rings 16 at their upper ends. Multiple sealing rings 16 are in contact with the first steel cable 11 that is close to them. The installation of sealing rings 16 can seal the buffer cylinders 9, so that the buffer cylinders 9 can maintain a sealed state and the pressure inside the buffer cylinders 9 can be kept balanced. Multiple first springs 8 and multiple elastic elements 15 are treated with anti-rust and anti-corrosion. The anti-corrosion treatment of the first springs 8 and elastic elements 15 can improve their corrosion resistance and prevent them from being corroded by water, which would lead to a decrease in elasticity.

[0033] In this embodiment, a river dredging vessel using a chain bucket can reduce the vibration generated when the bucket 5 contacts the bucket bridge 2 by installing a first spring 8 in cooperation with a contact rod 7, thus keeping the bucket 5 in a stable state. By installing a buffer cylinder 9 in cooperation with a sliding member 10, the abnormal noise emitted by the bucket 5 when it is overturned can be reduced, thus keeping the bucket 5 stable. This reduces the noise and vibration transmitted by the bucket 5 during operation, enabling the dredging work to be carried out stably.

[0034] The working principle of the above embodiment is as follows: First, the hull 1 drives the bucket bridge 2 to swing, so that one end of the bucket bridge 2 is submerged underwater. Then, the drive equipment on the hull 1 drives the right-side transmission roller 3 to rotate. Through the transmission of the sprocket and chain, the two transmission rollers 3 can rotate synchronously. When the two transmission rollers 3 rotate, they can drive multiple buckets 5 to perform dredging work in a cyclical manner through the bucket chain 4. During this process, the cooperation of the first spring 8 and the contact rod 7 can reduce the vibration generated when the bucket 5 contacts the bucket bridge 2, so that the bucket 5 can maintain a stable state. The contact rod 7 is made of rubber to prevent the bucket 5 from colliding with the bucket bridge 2 when it is heavy, thus avoiding excessive noise and instability, thereby improving the stability of the bucket 5. When the bucket 5 moves onto the sliding buffer 14, the cooperation between the sliding buffer 14 and the elastic element 15 allows for flexible contact between the contact rod 7 and the sliding buffer 14, while also preventing excessive noise. The upper surface of the sliding buffer 14 is made of rubber to improve the overall buffering capacity of the bucket 5, thereby preventing instability caused by rigid contact. When the bucket 5 moves to the right drive roller 3, The bucket 5 will tilt. During the tilting process, the first steel cable 11 drives the sliding member 10 to slide inside the buffer cylinder 9, so that the buffer cylinder 9 can be in a negative pressure state. With the cooperation of the second spring 13, the deformation force of the second spring 13 can drive the sliding member to return to its original position. At the same time, it can buffer the swinging force of the bucket 5, so that the bucket 5 can swing stably. By installing the buffer cylinder 9 and the sliding member 10, the abnormal noise emitted by the bucket 5 during tilting can be reduced, so that the bucket 5 can remain stable, reduce the noise and vibration transmitted by the bucket 5 during operation, and make the dredging work stable.
