Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] Such as figure 1 and figure 2 As shown, the top of the tamper 6 is provided with a counterbore 9, and the flange 10 at the bottom of the pull ring 1? The tamper 6 is connected as a whole by the bolt 2, a buffer pad 5 is placed at the bottom of the counterbore 9, the large end of the pull rod 4 is placed on the buffer pad 5, and a Buffer spring 3 is arranged, and the top of buffer spring 3 is fixed by the flange of the bottom of draw ring 1, and pull bar 4 passes buffer spring 3, and the end links to each other with wire rope 7, and wear-resisting hammer end 8 is welded on the end of rammer 6.

[0020] Such as figure 1 and figure 2 As shown, when the pile driver uses the rammer to tamp the bottom of the expanded hole, the composite rammer with its own buffer device is lifted to a certain height, and the rammer 6 falls freely through...

Abstract

The invention discloses a composite pounder with a buffering device. The composite pounder comprises a pounder (6), wherein the top of the pounder (6) is provided with a counter bored hole (9); the buffering device is arranged in the counter bored hole (9); a flange on the lower part of a pull ring (1) is in conveniently detachable connection with the pounder (6); and the buffering device is connected with a steel wire rope. The composite pounder with the buffering device effectively reduces impact on a hydraulic control system in the working process and ensures that a hydraulic system has certain response time when the pounder is lifted and leaves the ground.

Description

technical field [0001] The invention relates to a rammer, in particular to a composite rammer which is used for a static pressure sinking pipe grouting pile machine to tamp the bottom of a hole and has a buffer device. Background technique [0002] At present, the static pressure sinking pipe grouting machine must be equipped with a rammer of a certain weight in order to effectively tamp the bottom of the rammed and reamed hole before the pile hole is poured. During the working process, first raise the rammer to the set height, and then make the rammer fall freely through the control of the electro-hydraulic system, relying on the kinetic energy generated by the free fall of the rammer to tamp the bottom of the pile hole and increase the ground endurance at the bottom of the pile hole. After the rammer touches the ground, it is lifted rapidly, and the speed is instantly increased from zero to a certain value. The gravity of the tamper is loaded on the wire rope in a very sh...
