Abstract
Description
Technical Field
[0001] This utility model relates to the field of engineering construction technology, and in particular to a dredging device for construction engineering. Background Technology
[0002] Silt is a type of soft soil with a natural water content greater than its flow limit and a porosity greater than 1.5. It is a modern sediment formed in slow-moving environments such as bays, lakes, or river bends through the action of microorganisms. The presence of silt in the foundation can easily cause building subsidence; therefore, dredging is necessary before construction work in relatively damp areas.
[0003] Silt is often encountered during construction projects. Usually, silt in river channels is diluted. However, when the river is wide, workers need to stand in the middle to flush the silt. Usually, a wooden board is placed on the river and the workers stand on it to flush the silt. Although this method can remove silt, it is very difficult to place and retrieve the board, and the board is not easy to move in the silt. Summary of the Invention
[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.
[0005] The purpose of this utility model is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a dredging device for construction engineering.
[0006] The purpose of this utility model is achieved through the following technical solution: a dredging device for construction engineering, including a fixed frame, a motor fixedly connected to one side of the fixed frame, a rotating rod fixedly connected to the output end of the motor, a wire reel fixedly connected to the outer surface of the rotating rod, a connecting wire provided inside the wire reel, and connecting plates fixedly connected to the left and right sides of the bottom of the fixed frame, with anchor rods inserted into the inside of the connecting plates;
[0007] One end of the connecting line is fixedly connected to a clamping plate, and a clamping plate is snapped into the inside of the clamping plate. Bolts are inserted into the inside of the clamping plate and the clamping plate. An adjusting rod is fixedly connected to one side of the clamping plate. A threaded hole is opened inside the adjusting rod. A fixing cylinder is sleeved on the bottom of the adjusting rod. A fixing screw is threadedly connected to one side of the fixing cylinder. A pedal is fixedly connected to the bottom of the fixing cylinder. Rounded corners are opened on both the left and right sides of the pedal.
[0008] Preferably, there are two fixing brackets, which are located on the left and right sides of the pedal respectively, and both fixing brackets are fixedly connected to the pedal by connecting lines.
[0009] By adopting the above technical solution, two fixed frames driven by motors to rotate the reels can connect the two ends of the pedal. When the left reel releases the line, the right reel retracts the line, and the pedal moves to the right. Conversely, the pedal moves to the left, making it easy to adjust the position of the pedal on the silt.
[0010] Preferably, there are two coils, which are symmetrically arranged on the outer surface of the rotating rod. The connecting wire is made of steel wire. There are four connecting plates, which are symmetrically welded to the left and right sides of the bottom of the fixing frame.
[0011] By adopting the above technical solution, the fixing frame can be stably installed on the ground through the connecting plate and anchor rod.
[0012] Preferably, the internal dimensions of the clamping plate are adapted to the thickness of the card plate, and both the clamping plate and the card plate have round holes adapted to the bolts.
[0013] By adopting the above technical solution, the clamping plate and the card plate can be quickly snapped together, and the two can be quickly connected by bolts alone.
[0014] Preferably, the adjusting rod is a rectangular rod, and the number of threaded holes is several. Several adjusting rods are linearly arranged at the center of the adjusting rod, and the size of the threaded holes is adapted to the size of the fixing screw.
[0015] By adopting the above technical solution, the adjusting rod can be adjusted in terms of its extension and retraction length within the fixed cylinder by means of a fixing screw.
[0016] Preferably, there are four fixing cylinders, which are welded to the four corners of the top of the pedal. The top surface of the pedal is provided with a stainless steel layer, and the bottom of the pedal is a wooden layer.
[0017] By adopting the above technical solutions, the stainless steel top surface is more wear-resistant, which can increase the service life of the pedal, and the wooden pedal can float lightly on the mud surface.
[0018] Compared with the prior art, the present invention has the following advantages:
[0019] 1. The dredging device used in this construction project is equipped with a reel. The output end of the motor is fixedly connected to a rotating rod, and the outer surface of the rotating rod is fixedly connected to the reel. The reel contains a connecting wire. Two fixed frames driven by the motor to rotate the reel can connect the two ends of the pedal. When the left reel releases the wire, the right reel retracts the wire, and the pedal moves to the right. Conversely, it moves to the left. This makes it easy to adjust the position of the pedal on the silt and also makes it easy to place and retrieve the pedal, thus achieving the purpose of ease of use.
[0020] 2. The dredging device used in this construction project features an adjusting rod. An adjusting rod is fixedly connected to one side of the clamping plate. The adjusting rod has a threaded hole inside, and a fixed cylinder is fitted to the bottom of the adjusting rod. A fixing screw is threaded onto one side of the fixed cylinder. The adjusting rod can move up and down within the fixed cylinder. The fixing screw limits the extension and retraction length of the adjusting rod within the fixed cylinder. The height of the adjusting rod can be adjusted according to the surface height of the silt, ensuring the connecting line is as close to horizontal as possible, preventing contact with the ground, and not affecting the normal extension and retraction of the connecting line. The rounded corners on both sides of the pedal reduce the impact of the pedal on the silt when moving left and right. Attached Figure Description

[0028] With the above setup, the two fixed frames 1 driven by the motor 2 to rotate the reel 4 can connect the two ends of the pedal 15. When the left reel 4 releases the line, the right reel 4 retracts the line, and the pedal 15 moves to the right, and vice versa. This makes it easy to adjust the position of the pedal 15 on the silt, and also makes it easy to place and retrieve the pedal 15, thus achieving the purpose of being easy to use.
[0029] like Figure 1-4 As shown, one end of the connecting line 5 is fixedly connected to a clamping plate 8, a clamping plate 9 is snapped into the inside of the clamping plate 8, and bolts 10 are inserted into the inside of the clamping plate 8 and the clamping plate 9. An adjusting rod 11 is fixedly connected to one side of the clamping plate 9. A threaded hole 12 is opened inside the adjusting rod 11. A fixing cylinder 13 is sleeved on the bottom of the adjusting rod 11. A fixing screw 14 is threadedly connected to one side of the fixing cylinder 13. A pedal 15 is fixedly connected to the bottom of the fixing cylinder 13. Rounded corners 16 are opened on both the left and right sides of the pedal 15.
[0030] With the above settings, the adjusting rod 11 can move up and down inside the fixed cylinder 13. The fixing screw 14 can limit the extension and retraction length of the adjusting rod 11 inside the fixed cylinder 13. The height of the adjusting rod 11 can be adjusted according to the height of the silt surface, so that the connecting line 5 is as close to horizontal as possible, avoiding contact between the connecting line 5 and the ground, and not affecting the normal extension and retraction of the connecting line 5. The rounded corners 16 on both sides of the pedal 15 can reduce the impact of the pedal 15 on the silt when it moves left and right.
[0031] As a preferred technical solution of this utility model, there are two fixing brackets 1, which are located on the left and right sides of the pedal 15 respectively, and both fixing brackets 1 are fixedly connected to the pedal 15 through connecting lines 5.

[0034] As a preferred technical solution of this utility model, the adjusting rod 11 is a rectangular rod, and the number of threaded holes 12 is several. Several adjusting rods 11 are linearly arranged at the center of the adjusting rod 11, and the size of the threaded holes 12 is adapted to the size of the fixing screws 14.
[0035] As a preferred technical solution of this utility model, there are four fixing cylinders 13. The four fixing cylinders 13 are respectively welded to the four corners of the top of the pedal 15. The top surface of the pedal 15 is provided with a stainless steel layer, and the bottom of the pedal 15 is a wooden layer.
[0036] The working process of this utility model is as follows:
[0037] S1. The two fixed frames 1 can be fixed to both banks of the river channel by connecting plates 6 and anchor bolts 7;
[0038] S2, clamp 8 and clamp 9 can be quickly snapped together, and the two can be quickly connected by bolt 10. The connecting line 5 can be connected to the clamp 9 on the top of the pedal 15 through clamp 8. The fixing frame 1 is connected to the pedal 15 through the connecting line 5.
[0039] S3. When the left reel 4 releases the line, the right reel 4 retracts the line, then the pedal 15 moves to the right; conversely, the pedal 15 moves to the left, making it easy to adjust the position of the pedal 15 on the silt.
[0040] S4. The fixing screw 14 can limit the extension and retraction length of the adjusting rod 11 in the fixing cylinder 13. The height of the adjusting rod 11 can be adjusted according to the height of the silt surface so that the connecting line 5 is as close to horizontal as possible.
