Description

Technical Field

[0001] The utility model belongs to the technical field of dredging construction equipment, in particular to an assembled small-scale river channel hydraulic flushing and digging equipment. Background Art

[0002] In river dredging and other construction projects, it is usually necessary to use hydraulic flushing to remove silt. Hydraulic flushing refers to spraying water or mud at high speed to break up the silt and mix it with water or mud, eventually forming a slurry with strong fluidity. By increasing the fluidity of the silt, it is easier to extract and transfer, thus achieving the purpose of dredging and silting.

[0003] At present, in hydraulic flushing and excavation operations, it is usually necessary for multiple workers to hold high-pressure water guns and enter the drainage operation area to perform flushing and excavation operations. Specifically, a high-pressure water gun is manually held and aimed at the work surface to be flushed and excavated, and a high-pressure jet is ejected toward the flushing and excavation work surface. The aforementioned operation method consumes a lot of manpower, is inefficient, and has high operational risks, which are specifically reflected in the following aspects: First, the ground in the drainage operation area is not a hard ground, so it is inconvenient for construction workers to move in the drainage operation area, which is not conducive to continuous movement of positions during the flushing and excavation process; secondly, the manual flushing and excavation method requires construction workers to hold high-pressure water guns. Since the jet acts in the opposite direction on the personnel, in order for the construction personnel to hold the high-pressure water gun steadily, the pressure and flow rate of the jet cannot be too large, which affects the flushing and excavation effect of the jet on the silt; thirdly, in extreme cases, the jet in the high-pressure water gun will impact the construction personnel, causing construction accidents.

[0004] In summary, it is necessary to develop and design a river hydraulic flushing and excavation equipment to replace the current manual flushing and excavation operation method and solve the defects of the manual flushing and excavation construction method. Utility Model Content

[0008] Preferably, base ear plates are provided on both sides of the bottom of the adapter base, and the swing frame is in a U-shape, and the support plates on both sides thereof are hingedly connected to the two base ear plates by using rotating shafts.

[0009] Preferably, flanges are provided at the bottom of the upper disk body and the top of the lower disk body, and the two flanges are fixedly connected by bolts or clamps.

[0010] Preferably, two left and right assembly plates are provided on the top of the connecting plate, and the two assembly plates are respectively located on both sides of the lower base and are fixedly connected by bolts.

[0011] Preferably, an upper support arm is installed on the side of the adapter base, a lower support arm is installed on the side of the nozzle, the upper end of the cylinder body of the swing hydraulic cylinder is hingedly connected to the end of the upper support arm, and the lower end of the piston rod of the swing hydraulic cylinder is hingedly connected to the end of the lower support arm.

[0012] Preferably, the conveying pipeline passes through the rear part of the excavating arm and passes through the front part of the excavating arm, and the middle part of the conveying pipeline is arranged inside the excavating arm.

[0013] Preferably, a filter is installed at the end of the extraction line.

[0014] The advantages and positive effects of the utility model are:

[0015] The utility model provides a small-scale hydraulic flushing and excavation equipment for river channels with reasonable structural design. Compared with the existing hydraulic flushing and excavation facilities and hydraulic flushing and excavation methods based on manual methods, the hydraulic flushing and excavation equipment of the utility model is constructed based on excavator equipment, giving full play to the mobility and hydraulic driving ability of crawler excavators. It has the following effects: first, the excavator can move arbitrarily in the draining operation surface, and its walking crawler can be well supported by the draining operation surface, so it is not easy to sink, and the movement is flexible and fast. After completing the flushing and excavation operation at the current position, it can be quickly transferred to the next position to continue construction, which improves the construction efficiency; secondly, the excavation arm of the excavator can resist the stronger reverse effect of the hydraulic jet, so the pressure and speed of the jet ejected through the flushing and excavation device can be set to be larger, which can produce a stronger hydraulic flushing and excavation effect on the river channel silt, and improve the effect of hydraulic flushing and excavation construction; furthermore, when the hydraulic flushing and excavation construction is carried out by using the equipment, the construction personnel are the drivers of the excavator, who are located in the cab, so the hydraulic jet will not impact the construction personnel under any extreme circumstances, which improves the operation safety of hydraulic flushing and excavation construction.

[0016] The excavation device of the hydraulic flushing and excavation equipment is assembled from multiple parts from top to bottom, and the hydraulic flushing and excavation equipment is detachably connected to the front end of the excavation arm. Therefore, the hydraulic flushing and excavation equipment is an assembled device and a small device, which is convenient for installation and use on the excavator equipment. The flushing and excavation device can be disassembled for easy storage and transfer to the construction site for assembly and use. By installing a swing hydraulic cylinder between the adapter base and the nozzle, the nozzle can swing left and right. In addition, the excavator can drive the flushing and excavation device to swing up and down (the flushing and excavation device is installed at the original bucket position), so the jet direction can be adjusted up and down, left and right, so that the nozzle can be better aligned with the hydraulic flushing and excavation operation position.

Its operating principle is: the mud pump 4 extracts water or thin mud from the water area near the working area through the extraction pipeline 5, the water or thin mud is pressurized by the mud pump 4, and then transported to the flushing and excavation device 1 through the delivery pipeline 2, and finally ejected by the flushing and excavation device 1, so as to produce a hydraulic flushing and excavation effect on the river silt in the working surface.

[0024] The excavator 7 can be a general land excavator or a water excavator with a pontoon at the bottom. Different excavator equipment is selected according to different construction scenes. After the bucket originally configured on the excavator 7 is disassembled, the flushing and excavation device 1 is installed at the position where the original bucket was located, and the mud pump 4 is fixed to the chassis of the excavator 7 and connected to the power supply and control device in the cab of the excavator 7. During construction, the end of the extraction pipeline 5 is set in the waters near the construction area, and the mud pump 4 extracts water or thin mud from the nearby waters and pumps it to the flushing and excavation device 1 at high pressure.

[0025] In this embodiment, the delivery pipeline 2 passes through the rear of the digging arm 3 and passes through the front of the digging arm 3, and the middle part of the delivery pipeline 2 is arranged inside the digging arm 3.
