Technical Field

[0001] This utility model relates to the technical field of building construction, specifically a drilling device for building construction. Background Technology

[0002] Construction refers to the production activities during the implementation phase of a project. It is the process of building various types of buildings, or the process of turning the lines on the design drawings into physical objects at a designated location. It includes foundation construction, main structure construction, roof construction, decoration construction, etc. The place where construction work is carried out is called the "construction site" or "construction site". Drilling is often required during construction, and drilling equipment is used for this purpose.

[0003] However, existing drilling devices do not limit the drill bit during drilling, and the drill bit will generate a lot of vibration after drilling to the ground, which can easily cause the drill bit to shake, thereby changing the drilling position of the drill bit and affecting the drilling accuracy. Therefore, this application provides a drilling device for building construction to meet the needs. Utility Model Content

The reinforcement rod is installed on one side of the support frame, and fixing plates are fixed at both ends of the reinforcement rod. A fixing bolt passes through one side of the fixing plate.

[0011] Preferably, the reinforcing rod is threadedly connected to the support frame via a fixing bolt, and the reinforcing rod is symmetrically arranged about the central axis of the support frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. A drilling device for building construction, through the coordinated use of a column, a movable frame, a guide sleeve, a connecting rod, and a limiting ring, improves the stability of the movable frame's lifting and lowering process through the guide sleeve, allowing for a smoother lifting and lowering process. At the same time, after the drill bit reaches above the ground, the limiting ring limits the outer side of the drill bit, thereby preventing the drill bit from vibrating excessively and deviating, ensuring that the drill bit is in the preset drilling position, and improving the drilling accuracy of the device; 2.

Guide sleeve 7 is symmetrically arranged around the central axis of movable frame 6. Guide sleeve 7 matches the size of column 2. During the lifting and lowering process of movable frame 6, guide sleeve 7 can improve the stability of lifting and lowering of movable frame 6, and the lifting and lowering process can be carried out more smoothly. After drill bit 15 drills above the ground, limit ring 9 can limit the outside of drill bit 15, thereby avoiding large vibration of drill bit 15 and deviation, ensuring that drill bit 15 can be in the preset drilling position, and improving the drilling accuracy of the device. A connecting rod 8 is fixed on one side of movable frame 6, and a limit ring 9 is fixed below the connecting rod 8. Please see Figure 2-3A second motor 10 is installed on one side of the movable frame 6. A drive shaft 11 is installed at the lower output end of the second motor 10. A positioning bolt 12 passes through one side of the drive shaft 11. A connecting block 13 is installed inside the drive shaft 11. The connecting block 13 is threadedly connected to the drive shaft 11 through the positioning bolt 12. The positioning hole 14 is set corresponding to the positioning bolt 12. During long-term drilling operations, the drill bit 15 will wear out. The operator can pull out the positioning bolt 12, so that the connecting block 13 can be taken out from under the drive shaft 11, which is convenient for replacing the drill bit 15. A positioning hole 14 is opened on one side surface of the connecting block 13. The drill bit 15 is fixed below the connecting block 13. The drill bit 15 forms a rotating structure with the movable frame 6 through the drive shaft 11. The drill bit 15 and the central axis of the drive shaft 11 are matched, which is convenient for drilling the ground and has high efficiency. Please see Figure 1 and Figure 4 A reinforcing mechanism 16 is provided on one side of the support frame 3. The reinforcing mechanism 16 includes a reinforcing rod 1601, a fixing plate 1602, and a fixing bolt 1603. The reinforcing rod 1601 is installed on one side of the support frame 3. The fixing plates 1602 are fixed at both ends of the reinforcing rod 1601. The fixing bolt 1603 passes through one side of the fixing plate 1602. The support frame 3 can be connected to the base 1 through the reinforcing rod 1601, which improves the overall structural stability of the device. The device will not be at risk of tipping over when subjected to large vibrations. The reinforcing rod 1601 is threaded to the support frame 3 through the fixing bolt 1603. The reinforcing rod 1601 is symmetrically arranged about the central axis of the support frame 3. The reinforcing rod 1601 can be disassembled and assembled through the fixing bolt 1603, making the structure more flexible.

[0017] Working principle: When using this drilling device for construction, first connect the external power supply, then align the drill bit 15 with the drilling position, turn on the switch of the second motor 10 to drive the drill bit 15 to rotate, then turn on the switch of the first motor 4 to drive the lead screw 5 to rotate, driving the movable frame 6 to rise and fall, and then driving the drill bit 15 to descend to drill the ground. After the drill bit 15 drills above the ground, the outer side of the drill bit 15 can be limited by the limiting ring 9, which can prevent the drill bit 15 from vibrating too much and deviating, ensuring that the drill bit 15 can be in the preset drilling position. Finally, the drill bit 15 will wear out after long-term drilling operations. The operator can pull out the positioning bolt 12, so that the connecting block 13 can be taken out from under the drive shaft 11 for easy replacement of the drill bit 15. When the device is not in use, disconnect the external power supply. The model of the first motor 4 is 6IK200RGU-CF, and the model of the second motor 10 is XD-3420-2. This completes the use of the drilling device for construction.
