Embodiment 1

[0033] In order to realize the reliable and stable decoupling and hooking action of the piling hammer, this embodiment provides a decoupling device for the guide rod piling hammer, its structure see figure 1 As shown, it includes a decoupling frame 1, a decoupling actuator 2 that is installed on the decoupling frame 1 and can move up and down, and several groups of barb units located under the decoupling actuator 2. Each group of barb units is symmetrically arranged on the decoupling frame. Composed of two barbs 3, the barb 3 is rotatably arranged on the decoupling frame 1, the bottom of the barb 3 also extends laterally and forms a hook-shaped protrusion 4, and the upper part of the barb 3 is also provided with a side wall against the decoupling execution The opening slot 5 of the part 2; when the decoupling actuator 2 moves down to pin the opening slot 5, the barb 3 is locked and the two hook-shaped protrusions 4 are relatively close to and hooked on the piling hammer (that i...

Abstract

The invention relates to an unhooking device for a guide rod pile hammer. The unhooking device comprises an unhooking frame, an unhooking execution piece which is mounted on the unhooking frame and can move up and down, and two overhead hooks which are symmetrically arranged on the unhooking frame and are positioned below the unhooking execution piece; the overhead hooks are rotationally arranged on the unhooking frame; the bottoms of the overhead hooks extend laterally to form hook-shaped protrusions; the upper portions of the overhead hooks are further provided with open grooves with the side walls abutting against the unhooking execution piece; when the unhooking execution piece moves downwards to pin the open grooves, the overhead hooks are locked, and the two hook-shaped protrusions are relatively close to each other and hook the pile hammer; and when the unhooking execution piece moves upwards to be separated from the open grooves, the overhead hooks are unlocked, and the two hook-shaped protrusions are relatively far away from each other, so that unhooking of the pile hammer is achieved. Compared with the prior art, smooth unhooking of the pile hammer can be achieved.

Description

technical field [0001] The invention belongs to the technical field of high-end equipment manufacturing, and relates to a decoupling device for a guide rod piling hammer. Background technique [0002] As a kind of foundation piling equipment, the guide rod diesel piling hammer has been widely used in the construction of bridges, embankments, house construction and general construction projects. For example, the linkage-type guide rod diesel piling hammer disclosed in Chinese patent CN102304921A generally uses a hoist to lift the cylinder hammer during specific work, and after the hook of the undercarriage and the cylinder hammer is controlled to be unhooked, the cylinder hammer falls under its own gravity. , and cooperate with the cylinder compression ignition explosion to repeat the piling action of "rising-falling-rising". It can be seen that the decoupling action can be said to be a starting point of the piling work. At the same time, since the cylinder hammer moves up a...
