Embodiment Construction

[0025] The specific embodiments of the present invention will be further specifically described below through specific embodiments in conjunction with the accompanying drawings.

[0026] Such as figure 1 As shown, it is a structural diagram of a pile driver for civil engineering. The tail support rod 3 is fixed at the rear of the base 4. The tail support rod 3 includes a base, a hydraulic rod and a hinged joint. The hinged joint and the base are respectively located at both ends of the hydraulic rod. The seat is fixedly connected with the base 4, and the hinge joint is hinged with the end of the hammer rod 2. There is a thickened area in the middle of the hammer rod 2, and there is a hollow slot in the thickened area. The slot hole cooperates with the crankpin 11 of the crankshaft to form a sliding pair. The end is fixedly connected with the hammer head 5, the column 7 is fixedly installed on the front part of the base 4, the crankshaft 6 is installed on the column 7, one end ...

Abstract

The invention relates to the technical field of construction equipment, in particular to a pile driver. The pile driver for civil engineering comprises a base, a hammer rod and a hammer head and is characterized in that a tail supporting rod, a stand column, a crankshaft, a flywheel and a power device are further included; the tail supporting rod is fixed to the base, one end of the hammer rod ishinged to the tail supporting rod, and the other end of the hammer rod is fixedly connected with the hammer head; a thickening area is arranged in the middle of the hammer rod, and a groove hole is machined in the thickening area; the groove hole and a crank pin of the crankshaft cooperate to form a sliding pair, and crank arms are located on the two sides of the hammer rod; the stand column is fixed to the front portion of the base, a hinge hole is formed in the upper portion of the stand column, and the hinge hole and a main journal of the crankshaft are hinged; and one end of the crankshaftis fixedly connected with the flywheel, and the other end of the crankshaft is connected with the power device. The pile driver has the beneficial effects that the impact frequency and impact kineticenergy of a percussion hammer can be changed by adjusting the rotating speed of the crankshaft, and therefore the pile driver can adapt to pile driving work of different ground pile strengths, materials and sizes, and multiple purposes are achieved.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a pile driver. Background technique [0002] With the rapid development of national economic construction and infrastructure construction, all kinds of buildings continue to emerge, regardless of the size and purpose of the building, it is inevitable to use ground piles in a large number of buildings, because if large-scale ground buildings are to be built On the ground, the ground must bear a lot of pressure, so it is necessary to ensure that the ground has enough strength to resist the pressure, which is often difficult to do. Therefore, it is necessary to strengthen the ground bearing the building or improve the bearing mode of the ground, so it is thought of driving piles on the foundation, so that most of the weight of the building can be transmitted to a deep position below the ground through piles, because the foundation at this position is relatively deep. ...
