[0057] The highway bridge construction drilling platform refers to a work platform specially built to complete the drilling operation during the construction of bridge pile foundations. During the drilling operation, waste will continue to be generated in the hole, and conventional drilling platforms cannot clean the waste in the borehole. The bearing capacity of the pile foundation depends on the contact between the pile bottom and the bearing layer. If the waste covers the pile bottom, it will hinder the effective contact between the pile foundation and the bearing layer, thereby reducing the bearing capacity; at the same time, if the waste is not cleaned up and the sediment at the bottom of the hole is too thick, a weak interlayer will be formed at the bottom of the pile foundation, making it impossible to evenly transfer the load on the pile top to the bearing layer, which will lead to pile failure or settlement.

[0058] In view of the above technical problems, the present invention provides a highway bridge construction drilling platform, which can simultaneously meet the needs of drilling holes and cleaning the waste in the holes. The overall structure, working principle and technical effects of the highway bridge construction drilling platform provided by the present invention are described in detail below through embodiments and in conjunction with the accompanying drawings.

[0059] Please refer to Figure 1 and Figure 2 The present invention provides a highway bridge construction drilling platform, which is applied to the drilling operation during the bridge pile foundation construction. On the basis of satisfying the drilling operation, the present invention can also clean the waste in the hole to improve the bearing capacity of the pile foundation.

[0060] The highway bridge construction drilling platform provided by the present invention comprises a base plate 100, a mounting seat 200, a support column 300, a drilling mechanism, a cleaning mechanism, a flipping mechanism and a lifting mechanism, wherein the mounting seat 200 is arranged above the base plate 100, the support column 300 is installed on one side of the mounting seat 200, and the drilling mechanism and the cleaning mechanism are respectively installed at both ends of the support column 300. Among them, the drilling mechanism is used to drill holes on the ground, and the cleaning mechanism is used to clean the waste in the hole after the drilling is completed. The flipping mechanism is arranged on the mounting seat 200, the flipping mechanism is connected to the support column 300, and the flipping mechanism is used to drive the support column 300 to flip, thereby driving the drilling mechanism and the cleaning mechanism to rotate toward the ground respectively, so as to realize the switching of the drilling function and the cleaning function. At the same time, the lifting mechanism is also installed on the base plate 100, and the lifting mechanism is connected to the mounting seat 200, and the lifting mechanism is used to drive the mounting seat 200 to move in the vertical direction, thereby driving the support column 300 to approach or move away from the ground, so as to drive the drilling mechanism and the cleaning mechanism to operate close to the ground.

[0061] By setting up a drilling mechanism, a cleaning mechanism and a flipping mechanism and by switching the positions of the drilling mechanism and the cleaning mechanism, while satisfying the drilling operation through the drilling mechanism, the waste in the hole can also be cleaned through the cleaning mechanism to prevent the waste from remaining in the hole, hindering the effective contact between the pile foundation and the bearing layer, and reducing the bearing capacity.

The slider 402 is slidably arranged in the limit groove 401, and the slider 402 is arranged on both sides of the limit groove 401. The first motor 403 is installed between the two sliders 402, so that when the two sliders 402 move along the limit groove 401, the first motor 403 moves with the movement of the slider 402. The first threaded rod 404 is coaxially installed at the output end of the first motor 403, and the first threaded rod 404 is arranged along the length direction of the support column 300, and the thread of the first threaded rod 404 passes through the support column 300 and extends to the outside of the support column 300. A motor seat is fixedly connected to one end of the first threaded rod 404 outside the support column 300, and the second motor 405 is installed in the motor seat. The output end of the second motor 405 passes through the motor seat, and a fixing component is provided at one end of the output end of the second motor 405 outside the motor seat.

[0063] The first motor 403 drives the first threaded rod 404 to rotate. Since the first threaded rod 404 is threadedly connected to the support column 300, the first motor 403 is driven to move along the length direction of the limit slot 401, so as to drive the rotary drill bit 407 to move along the vertical direction to achieve drilling in the drilling operation. The second motor 405 drives the rotary drill bit 407 to rotate, so as to cut the soil layer through the rotary drill bit 407 to achieve the drilling effect.

When the fixing column 501 is clamped into the hollow column 406, the locking screw 502 penetrates the hollow column 406 and the fixing column 501 along the radial direction of the hollow column 406, thereby connecting the hollow column 406 and the fixing column 501, and achieving the effect of detachably mounting the rotary drill bit 407 on the second motor 405.

[0065] Please refer to Figure 1 and Figure 2 In some other optional embodiments, the cleaning mechanism includes a support block 601, a suction fan 602, a hollow tube 603 and a dust filter bag 604. Two support blocks 601 are arranged opposite to each other at one end of the support column 300 away from the drilling mechanism. The suction fan 602 is installed on the two support blocks 601, and the suction fan 602 is located on the side of the support block 601 away from the support column 300. The hollow tube 603 is connected and installed at the input end of the suction fan 602, and the hollow tube 603 is located at the end of the suction fan 602 away from the support block 601, and the hollow tube 603 extends along the length direction of the support column 300. The specific size of the hollow tube 603 is selected according to the size of the rotary drill bit 407 to meet the effect of the hollow tube 603 extending into the drill hole to suck the waste. The dust filter bag 604 is installed on one side of the support block 601, and the dust filter bag 604 is connected to the output end of the suction fan 602.

[0066] When cleaning the waste in the borehole, the cleaning mechanism is rotated to face the borehole, and the hollow tube 603 is driven to extend into the borehole.

[0067] Please refer to Figure 1 and Figure 4, in order to facilitate driving the support column 300 to flip, so as to drive the drilling mechanism and the cleaning mechanism to face the ground respectively. In other optional embodiments, the flipping mechanism includes a third motor 701, a first rotating gear 702, a rotating column 704 and a second rotating gear 703, the third motor 701 is mounted on the mounting seat 200, and the first rotating gear 702 is coaxially mounted on the output shaft of the third motor 701. The rotating column 704 is connected between the mounting seat 200 and the support column 300, and one end of the rotating column 704 is rotatably connected to the mounting seat 200, and the other end of the rotating column 704 is fixedly connected to the support column 300. The second rotating gear 703 is coaxially mounted on the rotating column 704, and the second rotating gear 703 is meshed with the first rotating gear 702. The third motor 701 drives the first rotating gear 702 to rotate, thereby driving the second rotating gear 703 meshed therewith to rotate, thereby driving the rotating column 704 to rotate, so as to achieve the effect of driving the support column 300 to rotate. Among them, in order to facilitate the installation and disassembly of the support column 300, a hollow block 705 is fixedly set at the end of the rotating column 704 away from the mounting seat 200, and the support column 300 is passed through and fixed on the hollow block 705. When the rotating column 704 drives the hollow block 705 to rotate, it drives the support column 300 to rotate, and the support column 300 is passed through the hollow block 705, which is convenient for disassembly and installation of the support column 300.

[0068] Please refer to Figure 1 and Figure 2 In some other optional embodiments, the lifting mechanism includes a support frame 801, a fourth motor 802 and a second threaded rod. The support frame 801 is a rectangular rod structure with a receiving groove inside. The support frame 801 is vertically mounted on the upper plate surface of the base plate 100. The fourth motor 802 is mounted on the top of the support frame 801, and the output shaft of the fourth motor 802 extends into the support frame 801 along the length direction of the support frame 801. The second threaded rod is rotatably arranged in the support frame 801 along the length direction of the support frame 801, and one end of the second threaded rod is coaxially connected with the output shaft of the fourth motor 802. The mounting seat 200 is an L-shaped plate body, one end of the mounting seat 200 is located in the support frame 801, and the second threaded rod is threaded through the mounting seat 200. Therefore, when the fourth motor 802 drives the second threaded rod to rotate, the mounting seat 200 is driven to move along the length direction of the support frame 801 to achieve the lifting and lowering of the support column 300, thereby achieving the effect of driving the drilling mechanism and the cleaning mechanism to approach or move away from the ground.

[0069] Please refer to Figure 1 and Figure 2, in order to facilitate the movement of the drilling platform to different drilling positions for operation and reduce the labor intensity of the operator. In some optional embodiments, a moving component is also provided on the base plate 100 to drive the base plate 100 to move. Among them, the moving component includes an electric push rod 901 and a universal wheel 902. A plurality of electric push rods 901 are provided on the upper plate surface of the base plate 100. In this embodiment, the electric push rods 901 are provided at the four corners of the base plate 100. The output shaft of the electric push rod 901 extends vertically downward and passes through the base plate 100. A universal wheel 902 is installed at the end of the output shaft of each electric push rod 901 to push the base plate 100. With the assistance of the universal wheel 902, the effect of facilitating the movement of the drilling platform is achieved. Furthermore, a plurality of storage grooves for accommodating the universal wheels 902 are provided on the lower surface of the base plate 100. When the drilling platform is moved into position, the universal wheels 902 are driven by the electric push rod 901 to move and be recovered into the storage grooves, so that the base plate 100 is placed on the ground, thereby providing good support during the drilling operation.

[0070] Please refer to Figure 1 and Figure 2 Further, in some optional embodiments, a slot for the support column 300 to pass through is provided on the bottom plate 100, so as to facilitate the operation of the drilling mechanism and the cleaning mechanism. In addition, a push-pull handle is provided on one side of the bottom plate 100, so as to facilitate workers to move the drilling platform.

[0071] In summary, the implementation principle of the highway bridge construction drilling platform of the present invention is as follows: by starting the electric push rod 901, it drives the universal wheel 902 to rise and fall. When it reaches the bottom of the base plate 100, it can drive the base plate 100 to move under the push of the worker. After moving to the preset position, the electric push rod 901 is started again to drive the universal wheel 902 to be stored in the storage groove. Then the fourth motor 802 is started to drive the second threaded rod to rotate, thereby driving the mounting seat 200 to rise and fall along the support frame 801. Then the first motor 403 is started to drive the first threaded rod 404 to rotate, and then under the action of the slider 402, the rotary drill bit 407 is driven to rise and fall, and then the second motor 405 is started to drive the hollow column 406 and the rotary drill bit 407 to rotate, so as to perform the drilling operation. After the drilling is completed, the fourth motor 802 can be started again to drive the mounting seat 200 to rise, and then the third motor 701 can be started to drive the first rotating gear 702 to rotate, and drive the second rotating gear 703 and the rotating column 704 meshed therewith to rotate, thereby driving the hollow block 705 and the support column 300 to rotate. Then the fourth motor 802 is started again to drive the mounting seat 200 to descend, so that the hollow tube 603 moves into the drill hole, and then the waste in the drill hole is sucked by starting the suction fan 602, and then filtered and collected by the dust filter bag 604 at the output end of the suction fan 602. The rotary drill bit 407 is prone to wear after long-term use. At this time, the locking screw 502 can be rotated to keep it away from the hollow column 406, so that the rotary drill bit 407 can be replaced.

[0072] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
