Description

Technical Field

[0001] This application relates to the technical field of pile foundation bottom cleaning, and particularly relates to a pile foundation bottom cleaning device for pile foundation construction. Background Technique

[0002] Pile foundation bottom cleaning is an important link in the process of pile foundation construction. Specifically, it refers to the process of cleaning the bottom of the pile foundation (such as bored cast-in-place piles) after the formation of the pile foundation. The main purpose of this process is to remove sundries, sediment, and sediment at the bottom of the pile to ensure the cleanliness of the pile bottom and provide a good foundation for subsequent pouring work.

[0003] For pile foundation bottom cleaning projects, two major cleaning strategies are usually adopted: manual and mechanical. Manual cleaning, as the name implies, relies on human power to meticulously remove various sundries accumulated at the bottom of the pile, ensuring that every inch of space is carefully attended to. Mechanical cleaning, on the other hand, uses advanced mechanical equipment, such as spray guns and high-efficiency suction pumps, to carry out faster and more efficient cleaning operations.

[0004] For traditional mechanical cleaning methods, it mainly relies on spray guns to inject strong water flow deep into the pile foundation to wash away the dirt accumulated at the bottom of the pile. Subsequently, the suction pump is responsible for pumping out the water flow mixed with sundries outside the pile foundation. However, when dealing with stubbornly solidified sundries at the bottom of the pile foundation, this method often requires a longer time for cleaning, reducing the cleaning effect of the device. Content of the Utility Model

[0005] The purpose of this application is to solve the problem of low cleaning efficiency of stubbornly solidified sundries at the bottom of the pile foundation by the method of using a spray gun in cooperation with a suction pump to pump out the dirt accumulated at the bottom of the pile foundation. This application provides a pile foundation bottom cleaning device for pile foundation construction.

[0006] This application specifically adopts the following technical solutions to achieve the above purpose:

[0007] A pile foundation bottom cleaning device for pile foundation construction includes a suction cylinder. One end of the suction cylinder is provided with an annular slide rail. Inside the annular slide rail, driving sliders are symmetrically and slidably connected. One end of the two driving sliders is fixedly connected to an annular mounting frame. One end of the annular mounting frame is symmetrically and rotatably connected to cleaning brushes. The top of the cleaning brushes is fixedly connected to an impulse gear ring. One end of the suction cylinder is fixedly connected to a driving motor. The output end of the driving motor is fixedly connected to a driving gear that meshes with the impulse gear ring. The inner top of the suction cylinder is fixedly connected to a water spray head, and the inner top of the suction cylinder is also fixedly connected to a water suction head. A water adjustment component is installed at one end of the water spray head. A lifting mechanism is installed on the top of the suction cylinder.

[0008] By adopting the above technical solution, through the combined use of the water transfer component and the lifting mechanism, it is convenient to drive the cleaning brush in the suction cylinder to the inner bottom of the pile foundation. Then, the flushing water flow is input into the pile foundation through the water spray head. Next, by starting the drive motor, the driving gear is engaged with the impulse gear ring, and the annular mounting frame and the two cleaning brushes are driven to rotate. At the same time, the cleaning brushes are used to brush the sundries at the bottom of the pile foundation, thereby improving the brushing effect of the cleaning brushes on the sundries inside the pile foundation and enhancing the cleaning efficiency of the device.

[0009] Furthermore, the water transfer component includes an arched support base arranged above the suction cylinder. One end of the arched support base is fixedly connected with a water supply pump. The output end of the water supply pump is fixedly connected with a water supply hose. The output end of the water supply hose is fixedly connected with the water spray head. One end of the arched support base is fixedly connected with a water extraction pump. The input end of the water extraction pump is fixedly connected with a water extraction hose. The input end of the water extraction hose is fixedly connected with the water extraction head.

[0010] By adopting the above technical solution, through the combined use of the water supply pump and the water supply hose, and the water extraction pump and the water extraction hose, it is convenient to start the water supply pump and the water extraction pump, and respectively input the flushing water flow into the pile foundation through the water supply hose and the water spray head. At the same time, the water extraction pump and the water extraction hose extract the water flow and sundries inside the pile foundation, effectively improving the practicability of the device.

[0011] Furthermore, the lifting mechanism includes a lifting screw fixedly connected to the top of the suction cylinder. One end of the arched support base is provided with a lifting through hole adapted to the lifting screw. The top of the arched support base is rotatably connected with a lifting worm gear threadedly connected to the lifting screw. The top of the arched support base is rotatably connected with a lifting worm engaged with the lifting worm gear. The top of the arched support base is fixedly connected with a lifting motor. The output end of the lifting motor is fixedly connected with the lifting worm. A guiding component is installed inside the lifting through hole.

[0012] By adopting the above technical solution, through the combined use of the guiding component, the lifting screw, the lifting worm gear, and the lifting worm, starting the lifting motor can drive the lifting worm to engage with the lifting worm gear. At the same time, the lifting worm gear is threadedly connected to the lifting screw. Then, in cooperation with the guiding component, the lifting screw is driven to drive the suction cylinder to move downward along the length direction of the lifting screw, so as to facilitate driving the suction cylinder to move towards the inner bottom of the pile foundation, further improving the practicability of the device.

[0013] Furthermore, the guiding component includes guiding sliders symmetrically and fixedly connected to the inner side of the lifting through hole. One end of the lifting screw is symmetrically provided with guiding sliding grooves adapted to the guiding sliders.

[0015] Furthermore, a first bevel gear is fixedly connected to the bottom of the suction cylinder, and one end of the cleaning brush passes through the annular mounting bracket and is fixedly connected to a second bevel gear meshing with the first bevel gear.

[0016] By adopting the above technical solution, by setting the cooperation between the first bevel gear and the second bevel gear, it is convenient to drive the annular mounting bracket to drive the two cleaning brushes to rotate, while making the cleaning brush drive the second bevel gear to mesh with the first bevel gear and drive the cleaning brush to rotate self - rotatably, thereby further improving the cleaning efficiency of the cleaning brush on the bottom of the pile foundation.

[0017] Furthermore, a pair of abutting balls are symmetrically ball - hinged to one end of the driving slider, and one end of the abutting balls forms a rolling abutment with the inner side of the annular slide rail.

[0018] By adopting the above technical solution, by setting the cooperation between the abutting balls and the driving slider, a rolling abutment is formed between the driving slider and the annular slide rail, thereby effectively reducing the wear between the driving slider and the annular slide rail.

[0019] Furthermore, a water level sensor is fixedly connected to the inner side of the suction cylinder, and a controller is fixedly connected to the top of the arched support base. The controller is electrically connected to the water supply pump, the water extraction pump, and the water level sensor.

[0020] By adopting the above technical solution, by setting the cooperation between the water level sensor and the controller, it is convenient to control the start and stop of the water extraction pump and the water supply pump according to the change of the water level inside the pile foundation, effectively improving the practicability of the device.

[0021] Furthermore, organic silicone waterproof coatings are applied to the surfaces of the suction cylinder and the annular slide rail.

[0022] By adopting the above technical solution, by setting the organic silicone waterproof coating, the rust resistance of the device is effectively improved, and the service life of the device is extended.

[0023] In summary, the present application includes at least one of the following beneficial effects:
