Description

Technical Field

[0001] The present application relates to the technical field of deep foundation pit excavation, and in particular to a drilling device. Background Art

[0002] At present, deep foundation pit excavation is a crucial link in the construction of power transmission line infrastructure in mountainous areas, especially in tunnel excavation, mountain highway bridge pile foundation excavation and power grid foundation pit excavation. It is widely used and has significant effects. Due to the complex terrain and large undulating terrain in mountainous areas, it is difficult for large-scale hole-forming machinery and equipment to enter the construction site. Therefore, the method of manually operated water-grinding drilling and manual coring has always been used. The water-grinding drilling construction process has many advantages such as low noise, high construction flexibility, low dust, low vibration, good hole quality, and no explosive safety problems. In addition, the water-grinding drilling construction process will not destroy the integrity of the rock mass, making the integrity of the pile wall and the pile bottom rock stronger, thereby improving the bearing capacity of the pile foundation, making the structure more stable and reliable, and providing a solid foundation for subsequent pile foundation reinforcement. However, at present, workers are still used to descend to the working area together with the water-grinding drill to perform on-site drilling operations.

[0104] In this embodiment, the drilling drive device 51, such as a permanent magnet synchronous motor, is decelerated and torque amplified by a reducer 53. Since the output shaft speed of the reducer 53 is relatively slow, an acceleration gearbox 54 is installed below it to make the speed of the drill bit 52 reach the average level of the engineering speed, and the water seal assembly 55 forms a sealed water-passing structure. Of course, it is not limited to this, and the drilling mechanism 5 may not include the reducer 53, the acceleration gearbox 54, and the water seal assembly 55, that is, the drilling drive device 51 may directly drive the drill bit 52 to rotate, which is selected according to actual needs.

[0108] In this embodiment, the water seal device assembly is connected and sealed with the output shaft of the acceleration gear box 54 and the main shaft of the drill bit 52 by a skeleton oil seal 552, and is limited by an elastic retaining ring 553. Preferably, a threaded hole is drilled in the middle part of the skeleton oil seal 552 for installing water pipes and other devices, and a countersunk hole is made along the axial direction at one end of the drill bit 52 so that the water seal device assembly and the drill bit 52 form a sealed water-permeable structure as a whole. It can be seen that the drill bit 52 structure is a water-grinding drill bit 52. Of course, it is not limited to this, and the type of drill bit 52 can also be selected according to actual needs.

[0109] In one embodiment of the present application, preferably, Figure 8 As shown, the number of the drill bit 52, the water seal assembly 55 and the output end of the acceleration gear phase are multiple and correspond to each other one by one.

[0115] In this embodiment, multiple drilling mechanisms 5 such as water-grinding drills can be controlled to perform drilling operations simultaneously, which greatly improves the operating efficiency.

[0116] In summary, the detailed working process of the drilling device provided by this application is as follows:

[0117] First, three traction ropes are connected to the lifting ring 127 on the supporting mechanism 1, and the whole device is lowered into the foundation pit through the ropes.

[0118] Then, the second screw 35, such as a small lead screw, is driven to rotate, thereby driving the middle and upper movable plate to move, causing the displacement adjustment mechanism 4 to extend and retract, driving the drilling mechanism 5 to move horizontally, and the drilling drive device 51, such as a motor, drives the drill bit 52 to rotate through the reducer 53 and the acceleration gear box 54;

[0119] Then, the first screw 32, such as a large lead screw, is driven to rotate, thereby driving the lower moving member 33 together with the displacement adjustment mechanism 4 and the drilling mechanism 5 to move downward or upward, that is, the drilling mechanism 5 is fed downward and raised upward to complete the drilling action;

[0120] Then the rotary drive device 21 is made such as a motor to drive the drilling mechanism 5 to rotate a certain angle according to different pit diameters, and the drilling action is continued until the free surface is drilled out, and finally the device is restored to the starting state and is raised by the rope. Of course, it is not limited to the above steps, and can also be adjusted according to actual needs.

[0121] Therefore, the present application provides a new type of automatic water-grinding drilling device for mountain rock foundation, which replaces the manually operated water-grinding drill and can automatically control multiple drilling mechanisms 5 such as water-grinding drills to perform drilling operations at the same time.
