Technical Field
[0001] This utility model belongs to the field of building construction technology, and more specifically, it relates to a deep drilling device for roadbed settlement reinforcement. Background Technology
[0002] In today's rapidly developing society, urbanization is constantly advancing and building heights are continuously increasing, which places more stringent demands on the stability of the foundation. To effectively ensure the stability of the foundation and prevent settlement, the commonly used method is to perform deep drilling on the foundation.
[0003] However, based on the current situation, existing drilling devices have a prominent problem when performing drilling operations: the inner walls of the drilled holes are usually very uneven. This unevenness causes many problems for subsequent steel reinforcement insertion and concrete pouring, thereby reducing the bearing capacity and stability of the entire foundation structure and posing potential risks to the quality of the construction project. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a deep drilling device for roadbed settlement reinforcement, which solves the problem that the hole wall formed after the existing foundation drilling device completes the drilling operation is obviously uneven, which makes it impossible to ensure a tight fit between the reinforcing bar and the hole wall when inserting the reinforcing bar or pouring concrete.
[0005] This utility model provides a deep drilling device for roadbed settlement reinforcement, which is achieved by the following specific technical means:
[0006] A deep drilling device for roadbed settlement reinforcement includes a triangular base plate; three sets of balance plates are arranged around the triangular base plate; a support plate is erected on the upper surface of the triangular base plate; a triangular top plate is fixedly connected to the top of the support plate; two guide columns are fixedly connected between the triangular top plate and the triangular base plate; a lead screw is rotatably connected between the triangular top plate and the triangular base plate; one end of the lead screw is connected to a first motor, and the body of the first motor is fixed to the triangular top plate; a first lifting frame and a second lifting frame are located between the guide columns and the lead screw; the first lifting frame and the second lifting frame are fixedly connected by a connecting sleeve. Each lifting frame is equipped with a sliding sleeve, which forms a sliding connection with the guide column. The second lifting frame is also equipped with a threaded sleeve, which forms a helical transmission connection with the lead screw. A rotating rod is inserted through the connecting sleeve, and a second motor is connected to the upper end of the rotating rod. The body of the second motor is fixed on the second lifting frame. The rotating rod is equipped with a helical chip removal groove, and a drilling and smoothing mechanism is provided at the lower end of the rotating rod. A drill bit is provided at the lower end of the drilling and smoothing mechanism. The drilling and smoothing mechanism includes a smoothing counterweight and smoothing arc plates. There are three sets of smoothing arc plates, which are arranged in a circular array, with the convex side of the smoothing arc plates facing outward.
[0007] Furthermore, the drill bit is provided with a spiral blade, and the spiral blade is aligned with the spiral chip removal groove in the same spiral direction; the drill bit has three vertical discharge holes.
[0008] Furthermore, the drilling and smoothing mechanism also includes two sets of fixed limiting rings, which are respectively fixedly connected to the rotating rod and the drill bit. A partition plate is fixedly connected between the two sets of fixed limiting rings through a connecting plate. There are three sets of partition plates, and the three sets of partition plates are connected to the central sleeve.
[0009] Furthermore, three sets of guide plates are fixedly connected to the outer side of the central sleeve, and a central connecting column is inserted through the central sleeve. A set of counterweight round handles is fixedly connected to each end of the central connecting column. The counterweight round handles are located in the fixed limiting ring to form a rotational connection, and three active drive rods are connected between the two sets of counterweight round handles.
[0010] Furthermore, a connecting sleeve is fitted onto the active drive rod, and a set of arc-shaped traction rods are fixedly connected to each end of the connecting sleeve. A driven drive rod is rotatably connected between the two sets of traction rods.
[0011] Furthermore, the driven rod passes through the counterweight block, which consists of three sets of counterweight blocks. The three sets of counterweight blocks are separated by a partition plate. The counterweight block has a guide plate groove, and the guide plate is located in the guide plate groove to form a sliding connection. The counterweight block is fixedly connected to the smoothing arc plate by a support plate.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. This utility model is equipped with a drilling smoothing mechanism. After the drilling operation is completed, the rotating rod slowly extends towards the ground surface. At the same time, it performs a reverse acceleration rotation. With the help of the inertia of the counterweight, the counterweight is pushed outward by the traction rod. At this time, the smoothing arc plate contacts the inner wall of the borehole. The counterweight applies pressure, and the smoothing arc plate rotates at high speed against the inner wall of the borehole, thereby smoothing the inner wall and effectively reducing its unevenness, creating favorable conditions for subsequent rebar insertion.
[0014] 2. This utility model is provided with a first lifting frame and a second lifting frame, which are spaced apart and fixedly connected by a connecting sleeve. The rotating rod passes through the connecting sleeve and works in conjunction with the guide column to limit the sliding sleeve. In this way, when the drill bit gradually penetrates deeper into the foundation, the rotating rod can significantly improve the stability of the rotation during drilling operations under the synergistic effect of this structure, thereby maintaining the integrity of the hole wall.

[0023] Example:
[0024] As attached Figure 1 To be continued Figure 5 As shown:
[0025] This utility model provides a deep drilling device for roadbed settlement reinforcement, including a triangular base plate 1; three sets of balance plates 2 are arranged around the triangular base plate 1; a support plate 3 is erected on the upper surface of the triangular base plate 1; a triangular top plate 4 is fixedly connected to the top of the support plate 3; two guide columns 5 are fixedly connected between the triangular top plate 4 and the triangular base plate 1; a lead screw 6 is rotatably connected between the triangular top plate 4 and the triangular base plate 1; one end of the lead screw 6 is connected to a first motor 7; the body of the first motor 7 is fixed on the triangular top plate 4; a first lifting frame 8 and a second lifting frame 9 are located between the guide columns 5 and the lead screw 6; the first lifting frame 8 and the second lifting frame 9 are fixedly connected by a connecting sleeve 10; the first lifting frame 8 and the second lifting frame 9 are... Each is equipped with a sliding sleeve 11, which forms a sliding connection with the guide column 5. The second lifting frame 9 is also equipped with a threaded sleeve 12, which forms a helical transmission connection with the lead screw 6. A rotating rod 14 is inserted through the connecting sleeve 10. The upper end of the rotating rod 14 is connected to a second motor 13, and the body of the second motor 13 is fixed on the second lifting frame 9. The rotating rod 14 is equipped with a spiral chip removal groove 15, and the lower end of the rotating rod 14 is equipped with a drilling and smoothing mechanism. The lower end of the drilling and smoothing mechanism is equipped with a drill bit 29. The drilling and smoothing mechanism includes a smoothing counterweight 27 and a smoothing arc plate 28. There are three sets of smoothing arc plates 28, which are arranged in a circular array, and the side of the smoothing arc plate 28 protrudes outward.
[0026] Among them, such as Figure 3 As shown, the drill bit 29 is provided with a spiral blade 30, and the spiral blade 30 is in the same spiral direction as the spiral chip removal groove 15; three discharge holes 31 are vertically penetrating the drill bit 29; when the rotating rod 14 drives the drill bit 29 to rotate, the foundation is crushed through the spiral blade 30, some of the debris reaches the top of the drill bit 29 through the discharge holes 31, and another part of the debris reaches the top of the drill bit 29 from the outside of the spiral blade 30. Then the debris is transported from the bottom of the hole to the surface through the spiral chip removal groove 15.
[0027] Among them, such as Figure 4As shown, the drilling and smoothing mechanism also includes two sets of fixed limiting rings 16, which are fixedly connected to the rotating rod 14 and the drill bit 29 respectively. A partition plate 18 is fixedly connected between the two sets of fixed limiting rings 16 through a connecting plate 17. There are three sets of partition plates 18, which are connected to the central sleeve 19. The rotating rod 14 and the drill bit 29 are fixedly connected in sequence through the fixed limiting rings 16, the connecting plate 17, the partition plate 18, the connecting plate 17, and the fixed limiting rings 16.
[0028] Among them, such as Figure 4 As shown, three sets of guide plates 20 are fixedly connected to the outside of the central sleeve 19, and a central connecting post 22 is inserted through the central sleeve 19. A set of counterweight round handles 21 are fixedly connected to each end of the central connecting post 22. The counterweight round handles 21 are located in the fixed limiting ring 16 to form a rotatable connection. Three active drive rods 23 are connected between the two sets of counterweight round handles 21. The counterweight round handles 21, the central connecting post 22 and the active drive rods 23 together constitute an inertial counterweight, which forms a rotatable connection between the two sets of fixed limiting rings 16. When the rotating rod 14 rotates, the inertial counterweight does not rotate synchronously with the rotating rod 14 in real time.
[0029] Among them, such as Figure 5 As shown, a connecting sleeve 24 is fitted onto the active drive rod 23, as... Figure 4 As shown, each end of the connecting sleeve 24 is fixedly connected to a set of arc-shaped traction rods 25, and a driven rod 26 is rotatably connected between the two sets of traction rods 25; the driven rod 26 passes through the counterweight 27, which consists of three sets, separated by a partition plate 18. The counterweight 27 has guide slots, and the guide plate 20 is located within these guide slots to form a sliding connection; the counterweight 27 is fixedly connected to the smoothing arc plate 28 via a support plate; during drilling operations... When the rotating rod 14 rotates forward, the active drive rod 23 of the inertial counterweight pulls the driven drive rod 26 in the opposite direction through the traction rod 25, causing the counterweight block 27 to move. In conjunction with the guide plate groove, the guide plate 20 is limited, causing the counterweight block 27 to move inward, and the three sets of smoothing arc plates 28 to retract towards the center. After the drilling operation is completed, the rotating rod 14 rotates in the opposite direction to accelerate, and pushes the driven drive rod 26 in the forward direction through the traction rod 25, causing the three sets of smoothing arc plates 28 to separate outward.
[0030] The specific usage and function of this embodiment are as follows:
[0031] In this invention, the first motor 7 drives the lead screw 6 to rotate, which, in conjunction with the guide column 5 limiting the sliding sleeve 11, causes the lead screw 6 to helically drive the threaded sleeve 12, driving the first lifting frame 8 and the second lifting frame 9 to move vertically, thereby changing the depth of the rotating rod 14 into the foundation borehole. The second motor 7 then drives the rotating rod 14 to rotate forward, causing the drill bit 29 to rotate. The drill bit 29 is then crushed by the spiral blade 30. Some of the debris reaches the top of the drill bit 29 through the discharge hole 31, while the remaining debris reaches the top of the drill bit 29 from the outside of the spiral blade 30. The debris is then transported from the bottom of the hole to the surface through the spiral chip discharge groove 15. During the drilling operation, the rotating rod 14 continuously extends into the foundation borehole while simultaneously rotating forward. The active drive rod 23 of the inertial counterweight pulls the driven drive rod 26 in the opposite direction through the traction rod 25, causing the counterweight block 27 to move. In conjunction with the guide plate groove, the guide plate 20 is limited, causing the counterweight block 27 to move inward, and the three sets of smoothing arc plates 28 to retract towards the center. After the drilling operation is completed, the rotating rod 14 slowly extends towards the ground surface. At the same time, the rotating rod 14 rotates in the opposite direction with accelerated rotation. Through the traction rod 25, the driven drive rod 26 is pushed forward, and the three sets of smoothing arc plates 28 separate outward. The smoothing arc plates 28 contact the inner wall of the borehole and apply pressure through the counterweight block 27. The smoothing arc plates 28 press against the inner wall of the borehole and rotate at high speed, thereby smoothing the borehole and reducing the unevenness of the inner wall, which is conducive to the subsequent rebar insertion work.
