Problems solved by technology
When pulling out the pile, the pile body is usually tightened with a steel wire rope, and then the hoist is started to wind up the wire rope to pull the pile body from the soil layer. There is a problem that the wire rope locking operation is not convenient and reliable enough.
There are also special clamps for pile extraction. The two clamp arms are opened or tightened under the drive of the horizontal drive mechanism to clamp / release the pile body, and then the clamp is driven up and down by starting the longitudinal drive mechanism to pull the pile. The clamping and lifting actions of the clamp are separately equipped with a driving mechanism, resulting in a complex structure of the equipment and high manufacturing costs
In view of the unsatisfactory cost performance of the existing clamps when pulling out piles, it cannot be well applied to small-scale engineering applications such as garden construction

The embodiment of the invention discloses a clamp. The clamp is characterized in that the first ends of two upper jaw arm clamps of the clamp are rotationally installed on lower jaw plates, arc-shapedsliding grooves are formed in the second ends of the two upper jaw arm clamps respectively and used for allowing arm clamp driving pins to be installed therein in a penetrating mode, and when the lower jaw plates and the two arm clamp driving pins move along with a driving device, the clamp clamps and locks a pile body to be pulled. The above clamp is installed on a rack of the pile pulling machine, and during operation, the two upper jaw arm clamps are driven to clamp a pile to be pulled for pile pulling so that the small pile body can be pulled out conveniently and quickly, and the high cost performance is achieved.
Description
technical field [0001] The invention relates to the technical field of power tools, in particular to a clamp and a pile extractor, which is especially suitable for small projects such as garden construction. Background technique [0002] For occasions such as garden construction, often need to carry out pile extraction operation, be about to be placed in the square or circular pile of other types of soil layer and pull out ground. When pulling out the pile, the pile body is generally tightened with a steel wire rope, and then the hoist is started to take up the wire rope to remove the pile body from the soil layer. There is a problem that the wire rope locking operation is not convenient and reliable enough. There are also special clamps for pile extraction. The two clamp arms are opened or tightened under the drive of the horizontal drive mechanism to clamp / release the pile body, and then the clamp is driven up and down by starting the longitudinal drive mechanism to pull t...
