Description

Technical Field

[0001] This utility model relates to the field of pile extraction machine technology, and in particular to a pile extraction device for civil engineering. Background Technology

[0002] A hydraulic pile extractor is an engineering device that uses the powerful pulling or vibration force generated by a hydraulic system to pull piles out of the ground. It is widely used in pile demolition or recycling operations in construction, bridge, dock and other engineering projects.

[0003] The main components are: a hydraulic system, the core power source, including hydraulic pumps, cylinders, motors, control valves, and high-pressure oil pipes, which provides a stable high-pressure oil flow to drive the pulling or vibrating action of the pile extractor; a clamping device, used to firmly clamp the pile head (such as precast concrete piles, steel piles, etc.), common types of which include mechanical clamps, hydraulic clamps, or chain locking mechanisms; and a power station (hydraulic pump station), driven by a diesel engine or electric motor, which provides power to the hydraulic system and is usually equipped with cooling and filtration devices.

[0004] In actual working conditions, most pipe piles have a lot of soil attached to their surface. When the pile extractor clamps the pipe pile and lifts it up little by little, the soil on the pipe pile is scraped off and often accumulates on the upper side of the pile extractor after the relative movement between the pipe pile and the clamping parts. The soil adhesion increases the frictional resistance between the pile extractor and the pipe pile. Hard soil or stones may damage the mechanical parts. Moreover, the soil accumulation on the upper side of the pile extractor makes it difficult to observe the integrity of the pipe pile, such as cracks and corrosion. When a large amount of soil accumulates, it needs to be cleaned manually with a shovel.

[0005] Therefore, a novel pile foundation extraction device capable of self-cleaning soil and preventing soil accumulation is proposed. Utility Model Content

[0006] To address the aforementioned problems, this utility model provides a pile extraction device for civil engineering, which can effectively reduce the amount of soil on the pipe pile, prevent the soil from being scraped down and accumulating on the upper side of the pile extractor after the pipe pile is raised, realize automated cleaning operation, eliminate the need for manual cleaning, and improve the operational stability of the pile extractor.

[0007] The technical solution adopted to solve the above technical problems is: a pile extraction device for civil engineering, including a pile extraction machine body, a pipe pile, a support and a scraper. The pile extraction machine body is connected to the support on both sides below. The support rotates around the axis of the pipe pile. The scraper is movably connected to the support and rotates with the support. The scraper is used to scrape off the soil on the outer wall of the pipe pile.

[0008] Furthermore, it also includes a lead screw and a limiting rod. One end of the lead screw is rotatably connected to the scraper, the lead screw passes through the bracket, and the lead screw is threadedly engaged with the bracket. The end of the limiting rod is fixed to the scraper and then passes through the bracket, and the limiting rod is slidably connected to the bracket.

[0009] Furthermore, it also includes: the end of the lead screw is movably connected to the scraper, the end of the lead screw and the scraper are slidable, a spring is sleeved on the lead screw, and the spring provides elastic force to the scraper.

[0010] Furthermore, it also includes a slewing support, a gear ring, a hydraulic motor, and a gear set. The slewing support is coaxially connected to the lower side of the pile extractor body, the gear ring is rotatably connected to the slewing support, the two brackets are respectively connected to both sides of the gear ring, the hydraulic motor is connected to the lower side of the pile extractor body, and the gear set is rotatably connected to the lower side of the pile extractor body. The gear set links the gear ring with the output shaft of the hydraulic motor.

[0011] The beneficial effects of this utility model are as follows: This utility model sets a support on the lower side of the pile extractor body, the support rotates around the axis of the pipe pile, and a scraper is movably set on the support. The movable and adjustable scraper adapts to pipe piles of different sizes, so that the scraper abuts against the outer wall of the pipe pile. When the scraper rotates with the support, it scrapes the soil off the outer wall of the pipe pile. Working in conjunction with the pile extractor body, it first scrapes and cleans the pipe pile on the lower side, and then rises and pulls out the pipe pile. This effectively reduces the amount of soil on the pipe pile and prevents the soil from being scraped down and accumulating on the upper side of the pile extractor after the pipe pile rises. It realizes automated cleaning operation, eliminates the need for manual cleaning, and improves the operational stability of the pile extractor. Attached Figure Description

[0019] In the above embodiments, a support 3 is set on the lower side of the pile extractor body 1. The support 3 rotates around the axis of the pipe pile 2. A scraper 4 is movably set on the support 3. The movable and adjustable scraper 4 adapts to pipe piles 2 of different sizes, so that the scraper 4 abuts against the outer wall of the pipe pile 2. When the scraper 4 rotates with the support 3, it scrapes the soil off the outer wall of the pipe pile 2. Working in conjunction with the pile extractor body 1, the scraper 4 first scrapes and cleans the pipe pile 2 from the lower side, and then rises and pulls out the pipe pile 2. This effectively reduces the soil on the pipe pile 2 and prevents the soil from being scraped down and accumulating on the upper side of the pile extractor after the pipe pile 2 rises. This achieves automated cleaning operation without the need for manual cleaning and improves the stability of the pile extractor operation.

Two brackets 3 are respectively connected to both sides of the gear ring 9. The hydraulic motor 10 is connected to the lower side of the pile extractor body 1. The gear set 11 is rotatably connected to the lower side of the pile extractor body 1. The gear set 11 links the gear ring 9 with the output shaft of the hydraulic motor 10.

[0025] In the above embodiments, the hydraulic motor 10 drives the gear set 11 to rotate, the gear set 11 drives the gear ring 9 to rotate, and the gear ring 9 drives the bracket 3 to rotate to achieve the scraping and cleaning operation.

[0026] The working principle of this utility model is as follows: The pile extractor body 1 is set up at the position of the pipe pile 2. The screw 5 is turned with a wrench. Under the action of the limit rod 6, the scraper 4 moves on the support plate. The scraper 4 abuts against the outer wall of the pipe pile 2.
