Description

Drilling pile driver

Technical Field

The utility model relates to the technical field of land construction, in particular to a drilling pile driver.

Background

Since the ground building is built on the ground and the ground is subjected to a great pressure, the ground must have sufficient strength against the pressure, which is difficult to achieve, and therefore the ground bearing the building must be reinforced or the bearing way of the ground is improved, so that it is conceivable to pile the ground to transfer most of the weight of the building to a position deep below the ground through the pile, because the ground bearing capacity of the position is much larger than that of the ground.

In the drilling pile driver disclosed in the patent publication No. CN208845100U, a lifting motor is started to drive a main gear to rotate, a transmission chain rotates, a fixing member on the transmission chain drives a rack to move, so that the rack moves downwards, and a drill rod passes through a scraping barrel to drill the ground, however, the drilling pile driver has disadvantages in that, on one hand, the main gear rotates to drive the transmission chain to rotate, so that the fixing member on the transmission chain drives the rack to move, thereby achieving the purpose of drilling the ground by the drill rod, but the transmission chain can only drive the fixing member to move downwards, since the transmission chain has a certain toughness, a good ground drilling effect cannot be achieved, and on the other hand, the driving motor, the connecting shaft and the rotating rod are used to drill the ground, although the purpose of drilling can be achieved, the drill rod cannot be protected well, when the drill bit drills to hard substances on the ground, the rotating rod is enabled to rotate downwards all the time due to the fact that the rotating rod is not provided with a protection device, and therefore the drill bit is prone to being damaged.
