Technical Field

[0001] The utility model relates to the technical field of drilling holes in foundation pit construction, in particular to a drilling hole device for foundation pit construction. Background Art

[0002] The soil drilling in foundation pit construction is mostly carried out by spiral drilling machines. During the drilling process, the cutting head at the bottom of the spiral drill is used to crush the soil. During the rotation of the spiral drill, the waste soil produced by the cutting head is discharged from the drill hole.

[0003] However, the existing spiral drilling machines all use multiple manual operations to apply downward pressure to the drilling machine to perform drilling. This is not only laborious but also easily causes the drilled holes to be skewed, thereby affecting subsequent construction projects. Therefore, it is necessary to make certain improvements to the drilling device.

[0004] For this reason, we propose a drilling device for foundation pit construction. Utility Model Content

[0005] The main purpose of the utility model is to provide a drilling device for foundation pit construction. By installing a motor and a spiral drill bit on the upper and lower parts of a movable plate, the movable plate can be driven up and down by an electric cylinder to automatically drill the spiral drill bit, and the verticality of the drilling can be ensured.

[0008] A rotating base is fixedly installed inside the movable plate, a connecting plate is sleeved on the outer side of the rotating base, the connecting plate is movably installed in a sliding chamber, the sliding chamber is opened inside the movable plate, and the other end of the connecting plate away from the rotating base is fixedly sleeved on the outer side of the spiral drill bit.

[0009] Furthermore, a motor is movably mounted on the top of the movable plate, an output end of the motor is fixedly connected to the top of the spiral drill bit, an arc-shaped slide groove is provided on the top of the movable plate, and the interior of the arc-shaped slide groove is connected to the interior of the sliding chamber.

[0020] A rotating base 9 is fixedly installed inside the movable plate 3, and a connecting plate 11 is movably sleeved on the outer side of the rotating base 9. The connecting plate 11 is movably installed in a sliding chamber 13. The sliding chamber 13 is opened inside the movable plate 3, and the other end of the connecting plate 11 away from the rotating base 9 is fixedly sleeved on the outer side of the spiral drill bit 4;

[0021] The top of the movable plate 3 is movably mounted with a motor 7, the output end of the motor 7 is fixedly connected to the top of the spiral drill bit 4, the top of the movable plate 3 is provided with an arc-shaped slide groove 12, the interior of the arc-shaped slide groove 12 is connected to the interior of the sliding chamber 13; the arc-shaped slide groove 12 is used for the output end of the motor 7 and the spiral drill bit 4 to slide, the outer side of the spiral drill bit 4 is fixedly sleeved with a limit plate 8, and the top of the limit plate 8 is in contact with the bottom end of the movable plate 3;
