Pile cutter for construction engineering

Abstract

The invention relates to the technical field of construction machinery, and discloses a pile cutter for construction engineering, which includes a drill rod device, an adjustment groove is opened in the middle of the drill rod device, and a hydraulic oil cylinder is movably installed inside the adjustment groove. The middle part of the hydraulic cylinder is movably socketed with a drill rod, and the middle part of the top of the hydraulic cylinder is fixedly equipped with an adjusting fastening device which protrudes above the top surface of the drill rod device. An oil chamber is opened inside the hydraulic cylinder, The connection between the hydraulic cylinder and the oil inlet pipe is provided with an oil inlet hole, and the inside of the hydraulic cylinder is located between the oil cavity and the oil inlet hole. Vertical hole ball, the bottom of the vertical hole ball is fixedly connected with a hanging ball through a stay rope, and the middle part of the vertical hole ball is provided with an oil hole. long life.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a pile cutter for construction engineering. Background technique [0002] In construction projects, many concrete piles will be poured to play a supporting role, but when dismantling, due to its good solidification, it is necessary to use a pile cutter to cut them off and then dismantle them. There are also many prefabricated piles that need Partial cutting requires the use of a pile cutter. The pile cutter uses a hydraulic cylinder to act on the drill rod to insert it into the inside of the pile to cut it off, and then remove the cut part. However, the existing There are also some problems in the use of the pile cutter: [0003] 1. The concrete piles poured in the existing buildings basically use round piles and square piles. In this way, when cutting piles early, it is necessary to choose a pile cutter according to different pile shapes, and the pile cutter itse...

AI Technical Summary

Problems solved by technology

[0003] 1. The concrete piles poured in the existing buildings basically use round piles and square piles. In this way, when cutting piles early, it is necessary to choose a pile cutter according to different pile shapes, and the pile cutter itself is very heavy. The transportation and installation of the pile cutter will be subject to certain restrictions. At the same time, even round or square piles will have unevenness after pouring because their edges are in contact with other walls. The surface of the pile is not vertical, which is not conducive to better truncating the pile, and will also cause damage to the drill rod;

[0004] 2. When cutting piles, you will encounter uneven unevenness on the surface of concrete piles. At this time, since the pile cutting machine is used under the suspension of machinery such as excavators, it will lead to if the pile is suspended at a certain height when cutting piles. In the case of hydraulic drive, when the drilling rod is extended to act on the uneven surface of the uneven concrete pile, the raised side will be forced first to make the opposite end tilt up, so that the continued hydraulic drive will cause the cut pile to not be on the same plane. , not only the pile cutting efficiency is low, but also the inclined work will cause great damage to the hydraulic cylinder and drill rod, reducing its service life
