Description

Technical Field

[0001] This utility model relates to the field of pile extraction technology, specifically a pile extractor for a hydraulic breaker. Background Technology

[0002] A pile extractor is a mechanical device that removes piles using hydraulic jacking or high-frequency vibration technology. It mainly consists of a main unit and a power station. The device adopts an integrated lifting design, supports wireless remote control operation, and is compatible with H-beam steel piles, I-beam steel piles, and other pile types ranging from 300-900mm. It can operate in clay, sand, and soil layers containing a small amount of gravel. Its core working principle has two modes: hydraulic cylinders lift the pile segment by segment, and high-frequency vibration liquefies the soil to reduce frictional resistance and achieve pile extraction.

[0003] During the construction process, the removal of old equipment requires the extraction of piles. Directly breaking the piles results in a large number of piles remaining in the soil, making removal inconvenient. Therefore, it is necessary to extract the piles before further processing. Most pile extractors require separate operation, which increases the cost for the construction team. Therefore, we propose a pile extractor for hydraulic breakers, which works in conjunction with hydraulic breakers to achieve rapid pile extraction. It also features a simple structure and is easy to carry. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pile puller for hydraulic breakers, which solves the problem of high demolition costs associated with independent pile pullers mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pile puller for a hydraulic breaker, comprising a hydraulic breaker support shell, wherein a hydraulic breaker is fixedly supported inside the hydraulic breaker support shell, a hanging plate is movably fitted on the outer side of the rear top crossbar of the hydraulic breaker support shell, a movable sleeve is movably supported at the bottom end of the hanging plate, a flip plate is fixedly installed at the front end of the movable sleeve, a connecting rod is movably connected to the rear end of the movable sleeve, and a gravity clamp is movably supported at the bottom end of the connecting rod.

[0006] Optionally, a gasket is fixedly installed on the inner side of the bottom end of the gravity clamp, and the distance between the front end of the flip plate and the hanging plate is greater than the distance between the connecting rod and the hanging plate.

[0007] Optionally, the gasket is made of rubber, and the outer surface of the gasket has friction texture. The gravity clamp is located below the movable sleeve and the flip plate.

[0008] Optionally, the hydraulic breaker is located in the inner cavity of the hydraulic breaker support shell near the front end, and the breaker cone at the bottom of the hydraulic breaker is attached to the front side of the flip plate.

[0009] This utility model provides a pile puller for a hydraulic breaker, which has the following advantages:

[0010] This hydraulic breaker pile extractor features a movable sleeve with a tilting plate supported at the front and a hanging plate connected to the inside. During use, this creates a lever, positioning the tilting plate below the hydraulic breaker. A gravity clamp is attached to the rear of the movable sleeve via a connecting rod, utilizing the gravity clamp's properties in conjunction with upward pulling force to efficiently extract piles. The device is simple in design and easy to use. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Please see Figures 1 to 3 This utility model provides a technical solution: a pile extractor for a hydraulic breaker, including a hydraulic breaker support shell 1, a hydraulic breaker 2 fixedly supported inside the hydraulic breaker support shell 1, a hanging plate 3 movably mounted on the outer side of the rear top crossbar of the hydraulic breaker support shell 1, a movable sleeve 4 movably supported at the bottom end of the hanging plate 3, a flipping plate 5 fixedly installed at the front end of the movable sleeve 4, the cooperation of the hanging plate 3, the movable sleeve 4 and the flipping plate 5 can form a lever, thereby assisting in continuously applying a vibration force to the pile body, so that it loosens with the soil during the vibration friction process, the rear end of the movable sleeve 4 is movably connected to a connecting rod 6, the bottom end of the connecting rod 6 is movably supported by a gravity clamp 7, the setting of the gravity clamp 7 can assist in the stable clamping function and prevent the pile body and the gravity clamp 7 from loosening.

[0017] A shim 8 is fixedly installed on the inner side of the bottom end of the gravity clamp 7. The distance between the front end of the flip plate 5 and the hanging plate 3 is greater than the distance between the connecting rod 6 and the hanging plate 3. The shim 8 can help improve the friction. The hanging plate 3 can be hung on the front end of the breaker to assist the breaker in pulling out the pile body, thus realizing the extension of the function of the breaker.

[0018] The gasket 8 is made of rubber and has friction texture on its outer surface. The gravity clamp 7 is located below the movable sleeve 4 and the flip plate 5.

[0019] The hydraulic breaker 2 is located in the inner cavity of the hydraulic breaker support shell 1 near the front end, and the breaker cone at the bottom of the hydraulic breaker 2 is attached to the front side of the flip plate 5.

[0020] In summary, when using this hydraulic breaker pile puller, first hang the hanging plate 3 on the rear crossbar of the hydraulic breaker support shell 1, so that the top surface of the flipping plate 5 is in contact with the bottom of the hydraulic breaker cone 2. Then, by controlling the movable arm of the breaker cone, the hanging plate 3, the movable sleeve 4, and the flipping plate 5 are moved. The right end of the movable sleeve 4 drives the connecting rod 6 and the gravity clamp 7 to move, so that the bottom end of the gravity clamp 7 moves the pad 8 to above the pile to be pulled out, so that the gravity clamp 7 is lowered. After the bottom of the gravity clamp 7 contacts the pile, the gravity clamp 7 is lowered further, rotating around the central axis, and the bottom gravity clamp... Clamp 7 opens, allowing the bottom end of gravity clamp 7 and pad 8 to move to the outside of the pile. Then, gravity clamp 7 is lifted, and the bottom of gravity clamp 7 clamps the pile using gravity. Then, hydraulic breaker 2 is activated, continuously hammering the tilting plate 5. By continuously applying downward force to the tilting plate 5, the tilting plate 5 and movable sleeve 4 drive the connecting rod 6 around the bottom end of the hanging plate 3, applying an upward impact force, causing the connecting rod 6 to rise upward. This further stabilizes the gravity clamp 7 in clamping the pile while lifting the pile upward. At the same time, the movable lever arm is lifted, completing the removal of the pile.
