Description

Technical Field

[0001] The utility model relates to the technical field of pile driving and pulling machines, in particular to a double-acting force multi-section synchronous telescopic mechanism. Background Art

[0002] A pile driver is a pile-driving machine that uses vibration, static force or hammering to pull piles out of the ground. When the pile driver is working, the pile frame and the pile hammer are used to pull up the pile by gravity and friction with the pile body. When pulling out a pile, the soil around the pile body is first hammered or vibrated to loosen the soil, and then the pile body is pulled up while vibrating or hammering until the pile is pulled out. It is suitable for pulling out smaller piles or the remaining piles after static pile pressing, and the double-acting multi-section synchronous telescopic mechanism is one of the important components of the pile driver.

[0003] When the existing double-acting multi-section synchronous telescopic mechanism is in use, since the telescopic mechanism mostly fixes the hydraulic cylinder to a matching base with bolts and then installs the base, when the hydraulic cylinder is damaged and needs to be replaced, it is necessary to manually unscrew the bolts one by one with a wrench, which increases the labor intensity and makes disassembly troublesome.
