Description

Technical Field

[0001] The utility model relates to the technical field of cast-in-place piles, in particular to a green noise reduction and slag discharge device for a rotary drilling tube. Background Art

[0002] During the drilling process of the rotary drilling barrel, when encountering semi-dense rock and soil, broken rock, strongly weathered soft rock and other strata, it is easy for the slag inside the drill barrel to be dense and difficult to discharge when lifting the drill to unload the slag. When this happens, it is usually necessary to repeatedly rotate the drill barrel forward and backward, brake suddenly, and use the inertia of the drill barrel and the internal slag to discharge the slag. While rotary drilling and discharging slag, the collision between the drill barrel and the drill rod, and the drill rod and the transmission device will generate a lot of noise, causing the noise around the construction site to exceed the standard, affecting the normal life of nearby residents, and resulting in more complaints. In serious cases, it will be punished or even ordered to stop work for rectification, which is not conducive to green and harmonious construction. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] The green noise reduction and slag discharge device for the rotary drilling barrel in the embodiment of the utility model is used to solve the problem that noise is easily generated during the slag discharge process of the rotary drilling barrel, thereby realizing green and harmonious construction.

[0023] like Figure 1 - Figure 6 As shown, the green noise reduction and slag discharge device of the rotary drilling barrel includes a base 1 and a slag discharge column 2. The base 1 is placed firmly on the ground as the supporting part of the whole device to ensure the stability of the device during operation. The slag discharge column 2 is arranged on the base 1 in the up-down direction, and its lower end is connected to the base 1. In actual use, the rotary drilling barrel 3 filled with dense slag 4 is moved to the top of the slag discharge column 2 placed on the ground and the rotary drilling barrel 3 is moved down. The slag discharge column 2 penetrates into the slag 4 of the rotary drilling barrel 3. Through static close contact, with the help of the rotation of the rotary drilling barrel 3 and the up-and-down movement of the rotary drilling barrel 3, the dense slag 4 in the drill barrel is stirred, becomes loose and falls, and gradually separates from the rotary drilling barrel 3 under the action of the deadweight of the slag 4, so as to achieve green noise reduction and slag discharge.

[0024] In some embodiments, the slag discharge column 2 is made of a steel pipe column, which has high strength and can withstand a large workload. The diameter and length of the steel pipe column can be selected according to actual construction requirements to achieve the best slag discharge effect.

[0025] In some embodiments, in order to ensure a firm connection between the slag column 2 and the base 1, the lower end of the slag column 2 is fixed to the base 1 by welding, and the welding point is polished to ensure the welding quality and prevent loosening or breakage during use.

[0026] In other embodiments, Figure 1 and Figure 2 As shown, in order to enhance the stability of the connection between the slag column 2 and the base 1, a reinforcement is also provided at the lower end of the slag column 2. The reinforcement is made of a triangular steel plate 5, one right-angled side of which is welded to the outer wall of the slag column 2, and the other right-angled side is welded to the base 1. The triangular steel plate 5 has good stability and can effectively disperse and resist the stress from the slag column 2, thereby ensuring the stability of the device.

[0027] Specifically, multiple triangular steel plates 5 are arranged at intervals along the circumferential direction of the outer wall of the slag column 2, which can further improve the overall stability of the device. These triangular steel plates 5 are evenly spaced and reasonably distributed, which can effectively improve the bearing capacity of the device and ensure that the device can maintain stable performance under long-term and high-load working conditions.

[0028] Working principle:

[0029] When the pile hole is excavated, the rotary drilling rig is in place and the hole is drilled. For the hard ground when drilling the hole, as well as the upper dense fill layer or the layer containing construction waste, the rotary drilling barrel 3 is used for drilling. When drilling, light pressure and slow rotation are used, and the verticality of the drill hole is controlled to meet the requirements. After the rotary drilling barrel 3 is lifted out of the hole, Figure 3 As shown, the rotary drilling tube 3 is moved above the slag column 2, and the slag column 2 is placed at a designated position. Figure 4As shown, the rotary drilling tube 3 is aligned with the slag column 2 and slowly lowered, and the slag column 2 penetrates into the slag 4 in the rotary drilling tube 3. At the same time, Figure 5 As shown, the rotary drilling rig is operated to make the rotary drilling barrel 3 rotate slowly, as shown in FIG. Figure 6 As shown, the dense slag 4 inside the rotary drilling tube 3 is disturbed and loosened and discharged. After the rotary drilling tube 3 is discharged, it is moved into the pile hole to continue drilling. For the drill slag accumulated on the base 1, an excavator is used on site to clean it to the stacking position in time, and then it is loaded and transported out.

[0030] The utility model discloses a green noise reduction and slag discharge device for a rotary drilling barrel, which realizes the function of reducing noise when discharging slag during the drilling process of the rotary drilling barrel. It has the advantages of simple structure, convenient operation and remarkable effect. It is suitable for rotary drilling construction under various geological conditions and has good application prospect and promotion value.

[0031] Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the protection scope of the utility model.
