Description

Technical Field

[0001] The utility model relates to the technical field of geotechnical engineering, in particular to a drilling device capable of preventing deviation. Background Art

[0002] Geotechnical investigation is a key activity that aims to prepare detailed investigation documents by identifying, analyzing and evaluating the geological, environmental characteristics and geotechnical conditions of the construction site. This is essential for building construction projects. Geotechnical drilling equipment is one of the main tools for geotechnical investigation. It can collect rock and soil samples underground and obtain stratigraphic data by using different types of drill bits and drilling tools. The choice of geotechnical drilling equipment depends on the purpose of the investigation and the specific geological conditions.

[0003] However, due to its bulky nature, traditional drilling rigs usually have wheels installed on the bottom to increase their mobility. However, the wheels are prone to shaking and deflection, which in turn affects the stability of the drilling rig. This stability issue has an important impact on the safety and accuracy of drilling operations. In view of this, we propose a drilling device that can prevent deviation. Utility Model Content

[0008] The side wall of the motor is fixedly connected with a connecting rod, the connecting rod is sleeved with a movable rod, and the bottom end surface of the movable rod is fixedly connected with the cone.

[0009] Preferably, a mounting groove is provided on one side of the movable rod close to the cone, a spring 2 is fixedly connected to the inner top surface of the mounting groove, an end of the spring 2 away from the inner top surface of the mounting groove is fixedly connected to the mounting rod, and an end of the mounting rod away from the spring 2 is fixedly connected to a rubber pad.

[0010] Preferably, the upper gear ring is meshed with the lower gear ring, and the rotation of the upper gear ring drives the lower gear ring to move.

[0011] Preferably, one end of the movable rod away from the cone is fixedly connected to the limiting block, the side wall of the movable rod is sleeved with a spring 1, the spring 1 is fixedly connected to the limiting block, and the end of the spring 1 away from the limiting block is fixedly connected to the top end surface of the connecting rod, and the movable rod is reset by pulling the elasticity of the spring 1.

[0014] Compared with the prior art, the utility model provides a drilling device that can prevent deviation, and has the following beneficial effects:

[0015] 1. The anti-deviation drilling equipment has an upper gear ring, a lower gear ring and a cone. The cone is inserted into the soil to prevent the universal wheel from shaking and deflecting. At the same time, during the drilling process, lateral pressure from the soil or resistance from rocks may be encountered. These forces may cause the deviation or shaking of the drilling equipment. The insertion of the cone can increase the stability of the equipment in the drilling direction and reduce the impact of lateral force on the equipment. When the motor drives the shaft and the drill bit to drill, the upper gear ring drives the lower gear ring to rotate, and then drives the inner ring to rotate. The connecting rod and the inner ring provide additional support and stability, reduce the shaking and deviation of the drilling equipment, and make the drilling operation more stable and accurate.

[0016] 2. The anti-deviation drilling equipment has a mounting rod and a rubber pad. When the ground is a hard rock surface, the cone cannot be inserted into the rock, but the rubber pad contacts the ground, providing additional support for the drilling equipment and improving the stability of the equipment.

[0024] The hydraulic cylinder 4 pushes the motor 5 to move downward, so that the cross bar 7 moves downward, the connecting rod 8 moves downward, and the upper ring gear 9 is meshed with the lower ring gear 13. When the motor 5 drives the rotating shaft and the drill bit 6 to drill, the upper ring gear 9 drives the lower ring gear 13 to rotate, and then drives the inner ring 12 to rotate. Through the connecting rod 8 and the inner ring 12, additional support and stability are provided, reducing the shaking and deviation of the drilling equipment, making the drilling operation more stable and accurate. At the same time, when the motor 5 moves downward, it drives the connecting rod 14 and the movable rod 15 to move downward, so that the cone 17 is inserted into the soil to prevent the universal wheel 2 from shaking and deflecting.
