Progressive pile driving device for building construction

Abstract

The invention discloses a progressive pile driving device for building construction. The center of the upper portion of a device body is fixedly connected with a drive motor; the lower portion of thedrive motor is rotationally connected with a sleeve; the sleeve penetrates through the center of the upper portion of the device body and is rotationally connected with a retaining bearing of the device body; the lower portion of the sleeve is sleeved with a step shaft; the lower end of the step shaft is fixedly connected with a sleeve column; convex rings are arranged on the upper and lower portions of the sleeve column; the middle of the sleeve column is combined with the middle of a cross beam in a sleeving mode; the two ends of the cross beam are connected with sliding grooves in a slidingmode; and the sliding grooves are fixedly connected with the inner walls of two sides of the device body. According to the device, the sleeve drives a first bevel gear to rotate and then drives a second bevel gear and a driven shaft to rotate, the driven shaft drives a cam to rotate, reciprocated vertical movement of the cross beam and the sleeve column is achieved under the dual functions of a return spring and the cam, the sleeve column drives a threaded rod to rotate and vertically move in a reciprocated mode, the rotating threaded rod drives a drill column to vertically move in a reciprocated mode and downwards move relative to the threaded rod at the same time, and the punching depth of a puncher chip is continuously and progressively deepened.

Description

technical field [0001] The invention relates to a construction machine, in particular to a progressive piling device for construction. Background technique [0002] Pile driving refers to driving piles into the ground to make the foundation of the building firm. Because if 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 sufficient strength to resist pressure, which is often difficult to do, so it is necessary to reinforce the ground that bears the building or To improve the bearing mode of the ground, it is thought of driving piles on the foundation, so that most of the weight of the building is transmitted to a deep position below the ground through piles, because the foundation at this position is much larger than the bearing capacity of the ground. [0003] In the piling process, it is often necessary to use external force to impact the drill rod into the ground. The depth of the pil...

Problems solved by technology

[0003] In the piling process, it is often necessary to use external force to impact the drill rod into the ground. The depth of the pile is not completed in one pass. The depth of the pile required for a deeper pile often needs to be completed through multiple impacts. The existing piling equipment does not have the progressive drill rod. Impact function, there are many inconveniences
