Description

Technical Field

[0001] This utility model relates to the field of dredging equipment technology, and in particular to a dredging equipment for water conservancy construction. Background Technology

[0002] Dredging equipment used in water conservancy construction is specifically designed to remove silt and impurities from the bottom of water bodies, such as dredging excavators. It is crucial for the maintenance of water conservancy projects, the ecological protection of rivers and lakes, and the normal operation of municipal drainage systems.

[0003] During dredging operations, excavators often need to be driven into river channels filled with silt. However, some river channels are complex, and the silt often contains large rocks and other hard debris. If these debris hit the chassis of the excavator while it is moving, it may damage the chassis, and in severe cases, it may even affect the normal use of the excavator. Utility Model Content

[0004] This utility model is a water conservancy construction dredging device proposed to address the problem that some river channels have complex formations and often contain large stones and other hard debris in the silt. If these debris collide with the chassis of the dredging excavator during its operation, it may cause damage to the chassis, and in severe cases, it may even affect the normal use of the dredging excavator.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a water conservancy construction dredging equipment, including a chassis, with tracked wheels on both sides of the chassis, a vehicle body rotatably connected to the top of the chassis, a robotic arm on one side of the top of the vehicle body, a bucket rotatably connected to one end of the robotic arm, a protective device on one side of the chassis, the protective device including an extension plate, the outer surface of which is inserted into the inner wall of the extension plate, a connecting plate on the top of the baffle, a disassembly device between the connecting plate and the baffle, a threaded rod threadedly connected to the inner wall of the connecting plate, and one end of the threaded rod being disposed on the inner wall of the extension plate.

[0006] The effect achieved by the above components is as follows: by setting up a baffle, under the action of the threaded rod, rotating the threaded rod will drive the connecting plate to move in the vertical direction. The connecting plate will drive the baffle to slide synchronously on the inner wall of the extension plate until the baffle completely covers one side of the chassis, but does not completely exceed the bottom of the chassis. Then the baffle can protect the side of the chassis that is moving forward, which helps to prevent debris from directly hitting the chassis and causing damage to the chassis.

[0007] Preferably, one end of the threaded rod is fixedly connected to a bearing, and the outer surface of the bearing is fixedly connected to the inner wall of the extension plate.

[0008] The effect achieved by the above components is that by setting bearings, the friction between the threaded rod and the extension plate can be reduced when rotating the threaded rod, making it easier to rotate the threaded rod.

[0009] Preferably, an operating block is fixedly connected to the other end of the threaded rod, and the outer surface of the operating block is provided with protrusions.

[0010] The effect achieved by the above components is as follows: by setting the operating block, rotating the operating block can drive the threaded rod to rotate. At the same time, the outer surface of the operating block is provided with protrusions, which can effectively increase the friction of the outer surface of the operating block and have an anti-slip effect when rotating the operating block.

[0011] Preferably, the inner wall of the connecting plate is symmetrically fixedly connected with round rods, and one end of each of the two round rods is fixedly connected to the top of the extension plate.

[0012] The effect achieved by the above components is as follows: by setting the round rod, when the connecting plate moves vertically under the drive of the threaded rod, it will drive the connecting plate to slide synchronously on the outer surface of the round rod, so the round rod can play the role of limiting and guiding the connecting plate.

[0013] Preferably, a threaded push rod is symmetrically threaded onto one side of the extension plate, and a rotating block is fixedly connected to one end of the threaded push rod.

[0014] The effect achieved by the above components is as follows: by setting a threaded push rod, rotating the rotating block drives the threaded push rod to rotate, so that the threaded push rod extends and retracts on the inner wall of the extension plate until one end of the threaded push rod abuts against one side of the baffle, which can provide auxiliary fixation between the extension plate and the baffle, thereby making the fixation between the extension plate and the baffle more stable.

[0015] Preferably, the easy-to-disassemble device includes two slot blocks, one side of each slot block is symmetrically and fixedly connected to one side of the connecting plate, a threaded pin is inserted into the inner wall of each slot block, one end of each threaded pin is fixedly connected to one side of the baffle, and a nut is threaded onto the outer surface of each threaded pin.

[0016] The effect achieved by the above components is as follows: by setting a threaded pin, inserting the threaded pin into the inner wall of the slot block, inserting the baffle into the inner wall of the extension plate, and making one side of the slot block abut against one side of the baffle, and then putting a nut on one end of the threaded pin, rotating the nut so that one side of the nut abuts against one side of the slot block, the baffle and the connecting plate can be fixed, and it is also convenient to disassemble, maintain and replace the baffle separately.

[0017] Preferably, a rubber pad is fixedly connected to one side of the nut, and the outer surface of the threaded pin is inserted into the inner wall of the rubber pad.

[0018] The effect achieved by the above components is that by setting a rubber pad, one side of the nut can be replaced by the other side of the slot block, and the friction between the nut and the slot block is increased, making the nut less likely to loosen.

[0019] Preferably, a U-shaped block is symmetrically fixedly connected to one side of the baffle, and the outer surface of the slot block is inserted into the inner wall of the U-shaped block.

[0020] The effect achieved by the above components is that by setting up U-shaped blocks, the U-shaped blocks can assist in fixing and limiting the slot blocks, thereby improving the stability of the connection between the connecting plate and the baffle.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, by setting a baffle, under the action of the threaded rod, the threaded rod can drive the baffle to slide synchronously on the inner wall of the extension plate until the baffle completely covers one side of the chassis, but does not completely exceed the bottom of the chassis. Then the baffle can protect the side of the chassis that is moving forward, which helps to prevent debris from directly hitting the chassis and causing damage to the chassis.

Detailed Implementation

[0029] Example 1, referring to Figures 1-3As shown, this embodiment discloses a dredging equipment for water conservancy construction, including a chassis 1. Tracked wheels 2 are provided on both sides of the chassis 1. A vehicle body 3 is rotatably connected to the top of the chassis 1. A robotic arm 4 is provided on one side of the top of the vehicle body 3. A bucket 5 is rotatably connected to one end of the robotic arm 4. A protective device 6 is provided on one side of the chassis 1. The protective device 6 includes an extension plate 61. The outer surface of a baffle 62 is inserted into the inner wall of the extension plate 61. A connecting plate 63 is provided on the top of the baffle 62. A disassembly device 7 is provided between the connecting plate 63 and the baffle 62. The inner wall of the connecting plate 63 is threaded. A threaded rod 64 is connected, with one end of the threaded rod 64 set on the inner wall of the extension plate 61. By setting a baffle 62, the threaded rod 64 is rotated under the action of the threaded rod 64. The threaded rod 64 will drive the connecting plate 63 to move in the vertical direction. The connecting plate 63 will drive the baffle 62 to slide synchronously on the inner wall of the extension plate 61 until the baffle 62 completely covers one side of the chassis 1, but does not completely exceed the bottom of the chassis 1. Then the baffle 62 can protect the side of the chassis 1 that is moving forward, which helps to prevent debris from directly hitting the chassis 1 and causing damage to the chassis 1.

[0030] Reference Figure 2 and Figure 3 As shown, a bearing 65 is fixedly connected to one end of the threaded rod 64. The outer surface of the bearing 65 is fixedly connected to the inner wall of the extension plate 61. By setting the bearing 65, the friction between the threaded rod 64 and the extension plate 61 can be reduced when rotating the threaded rod 64, making it easier to rotate the threaded rod 64. An operating block 66 is fixedly connected to the other end of the threaded rod 64. The outer surface of the operating block 66 is provided with protrusions. By setting the operating block 66, rotating the operating block 66 can drive the threaded rod 64 to rotate. At the same time, the protrusions on the outer surface of the operating block 66 can effectively increase the friction on the outer surface of the operating block 66, providing an anti-slip effect when rotating the operating block 66.

[0031] Reference Figures 2-5 As shown, round rods 67 are symmetrically fixedly connected to the inner wall of the connecting plate 63. One end of each round rod 67 is fixedly connected to the top of the extension plate 61. By setting the round rods 67, when the connecting plate 63 moves vertically under the drive of the threaded rod 64, it will drive the connecting plate 63 to slide synchronously on the outer surface of the round rods 67. Thus, the round rods 67 can limit and guide the connecting plate 63. Threaded push rods 68 are symmetrically threaded into one side of the extension plate 61. One end of the threaded push rod 68 is fixedly connected to a rotating block 69. By setting the threaded push rod 68, rotating the rotating block 69 drives the threaded push rod 68 to rotate, so that the threaded push rod 68 extends and retracts on the inner wall of the extension plate 61 until one end of the threaded push rod 68 abuts against one side of the baffle 62. This can provide auxiliary fixation between the extension plate 61 and the baffle 62, thereby making the fixation between the extension plate 61 and the baffle 62 more stable.

[0032] Reference Figure 4 and Figure 5 As shown, the easy-to-disassemble device 7 includes two slot blocks 71. One side of the two slot blocks 71 is symmetrically fixedly connected to one side of the connecting plate 63. A threaded pin 72 is inserted into the inner wall of the slot block 71. One end of the threaded pin 72 is fixedly connected to one side of the baffle 62. A nut 73 is threadedly connected to the outer surface of the threaded pin 72. By setting the threaded pin 72, inserting the threaded pin 72 into the inner wall of the slot block 71 and the baffle 62 into the inner wall of the extension plate 61, and making one side of the slot block 71 abut against one side of the baffle 62, and then putting the nut 73 on one end of the threaded pin 72, rotating the nut 73, and making one side of the nut 73 abut against one side of the slot block 71, the baffle 62 and the connecting plate 63 can be fixed together. At the same time, it is also convenient to disassemble, maintain and replace the baffle 62 separately.

[0033] Reference Figure 4 and Figure 5 As shown, a rubber pad 74 is fixedly connected to one side of the nut 73, and the outer surface of the threaded pin 72 is inserted into the inner wall of the rubber pad 74. By setting the rubber pad 74, one side of the nut 73 can be replaced to abut against one side of the slot block 71, and the friction between the nut 73 and the slot block 71 can be increased, making the nut 73 less likely to loosen. A U-shaped block 75 is symmetrically fixedly connected to one side of the baffle 62, and the outer surface of the slot block 71 is inserted into the inner wall of the U-shaped block 75. By setting the U-shaped block 75, the U-shaped block 75 can assist in fixing and limiting the slot block 71, and can improve the stability of the connection between the connecting plate 63 and the baffle 62.

[0034] Working principle: When chassis 1 needs protection, rotating the operating block 66 drives the threaded rod 64 to rotate. Under the limit of the two round rods 67, the threaded rod 64 drives the connecting plate 63 to move vertically. The connecting plate 63 drives the baffle 62 to slide synchronously on the inner wall of the extension plate 61 until the baffle 62 completely covers one side of chassis 1, but does not completely exceed the bottom of chassis 1. Then, rotating the rotating block 69 drives the threaded push rod 68 to rotate, causing the threaded push rod 68 to extend and retract on the inner wall of the extension plate 61 until one end of the threaded push rod 68 abuts against one side of the baffle 62. This provides auxiliary fixation between the extension plate 61 and the baffle 62, allowing the baffle 62 to protect the chassis. The forward side is protected to prevent debris from directly impacting the chassis 1 and causing damage. When it is necessary to install the connecting plate 63 and the baffle 62, insert the threaded pin 72 into the inner wall of the slot block 71, insert the baffle 62 into the inner wall of the extension plate 61, and insert the slot block 71 into the inner wall of the U-shaped block 75, so that one side of the slot block 71 abuts against one side of the baffle 62. Then, put the nut 73 on one end of the threaded pin 72 and rotate the nut 73 so that the rubber pad 74 on one side of the nut 73 abuts against one side of the slot block 71. This can fix the baffle 62 and the connecting plate 63, and also facilitate the individual disassembly, maintenance and replacement of the baffle 62.
