Description

Technical Field

[0001] This utility model relates to the field of pile foundation drilling technology, and in particular to a drilling device for civil engineering pile foundations. Background Technology

[0002] In civil engineering or when dealing with soft soil foundations, civil engineering piles are often used to reinforce the foundation. In pile foundation engineering, in order to deepen the pile's embedment depth and make the pile fully contact the surrounding soil, drilling can be used to increase the pile's embedment depth until the design depth is reached, thereby improving the pile's bearing capacity and stability.

[0003] However, existing drilling equipment for civil engineering pile foundations usually has a single drilling method, and different drilling equipment needs to be replaced according to different drilling requirements, which is inconvenient to use. Utility Model Content

[0004] Therefore, the purpose of this utility model is to propose a drilling device for civil engineering pile foundations to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, one embodiment of this utility model provides a drilling device for civil engineering pile foundations, including a drilling fixing base connected to a winch. A high-strength drill bit for drilling is rotatably connected to the bottom of the drilling fixing base. A positioning pin for engaging the high-strength drill bit is fixedly installed inside the drilling fixing base. The positioning pin is signal-connected to a main control unit for automated control. The main control unit is signal-connected to a drill bit drive base for lifting and adjusting. A transmission gear set for mechanical transmission is fixedly installed inside the drill bit drive base. A drilling motor for providing power is fixedly installed at one end of the transmission gear set. A balance detection base for balance detection is fixedly installed at the center of the drilling fixing base. A stainless steel plate for guidance is fixedly installed on the top surface of the drilling fixing base. A magnetic counterweight for adjusting the balance of the drilling fixing base is attached to the surface of the stainless steel plate.

[0006] Preferably, the bottom of the drilling fixing base is provided with a connecting claw platform for supporting and fixing the high-strength drill bit. The connecting claw platform has an installation groove for accommodating the positioning pin, and the high-strength drill bit has a slot around its perimeter that engages with the positioning pin.

[0007] The above technical solution is adopted: by setting a connecting claw platform at the bottom of the drilling fixing seat, the high-strength drill bit can be stably supported, and an installation groove is opened inside the connecting claw platform to fix the positioning pin, so that the grooves around the high-strength drill bit can be engaged with the positioning pin, ensuring that the drill bit can be firmly fixed and will not loosen during operation, thus ensuring the stability of the high-strength drill bit in operation.

[0008] Preferably, in any of the above embodiments, the positioning pin includes an electric telescopic rod connected to the main control unit and a locking pin for engaging the high-strength drill bit. The electric telescopic rod is fixedly installed inside the drilling fixing seat, and one end of the electric telescopic rod is fixedly installed with a locking pin that moves inside the connecting claw platform.

[0009] The above technical solution is adopted: after receiving the instruction from the main control unit, the electric telescopic rod will drive the locking pin to move inside the connecting claw platform. It can control the locking pin to lock the high-strength drill bit according to the working requirements of the high-strength drill bit, ensuring that the drill bit will not shift during operation and improving the drilling accuracy. Alternatively, the locking pin can be moved out of the high-strength drill bit to allow the high-strength drill bit to rotate, which can change the working mode of the high-strength drill bit and increase the diversity of drilling methods.

[0010] Preferably, in any of the above embodiments, the drilling motor is fixedly installed inside the drilling mounting base, the transmission gear set includes a driving gear and a driven gear for mechanical transmission, the driving gear is fixedly installed at the output end of the drilling motor, the driving gear meshes with the driven gear, and the driven gear and the drill bit drive base are fixedly installed.

[0011] The above technical solution involves concealing the drilling motor inside the drilling mounting base. The drilling motor outputs power to drive the transmission gear set according to the requirements, so that the driving gear transmits the power of the drilling motor to the driven gear. The driven gear then drives the drill bit drive base to rotate, thus transmitting the power of the motor to the drill bit and making it rotate.

[0012] Preferably, in any of the above embodiments, the drill bit drive base includes a drive shaft for transmission, a pneumatic telescopic rod connected to the main control unit for signal connection, and a drive block for engaging the high-strength drill bit. The drive shaft is rotatably connected to the middle of the drilling fixed base and fixedly installed with the driven gear. A pneumatic telescopic rod is fixedly installed inside the drive shaft, and a drive block that slides on the surface of the drive shaft is fixedly installed at one end of the pneumatic telescopic rod.

[0013] The above technical solution is adopted: the drive shaft inside the drill bit drive seat is responsible for transmitting the power output by the motor to the drive block, so that the drive block drives the high-strength drill bit to rotate. When the pneumatic telescopic rod receives the signal from the main control unit, it will drive the drive block to slide on the drive shaft. The drive block can be inserted into the interior of the high-strength drill bit to make the drill bit rotate, or the drive block can be moved out of the high-strength drill bit to make the high-strength drill bit move with the drilling fixing seat.

[0014] Preferably, in any of the above embodiments, the balance detection seat includes a balance support for support, a smooth balance block for sliding, a laser rangefinder sensor for detecting the position of the smooth balance block, and red and green indicator lights connected to the main control unit. The balance support is fixedly installed on the top of the drilling fixture. The smooth balance block that can slide freely is provided inside the balance support. The laser rangefinder sensor connected to the main control unit is fixedly installed around the balance support. The red and green indicator lights are fixedly installed on the top of the balance support, and the number of red and green indicator lights is the same as the number of laser rangefinder sensors.

[0015] Preferably, in any of the above embodiments, the magnetic counterweight is movably connected to the interior of the drilling fixture, and the bottom of the magnetic counterweight is provided with a magnet that magnetically attracts the stainless steel plate.

[0016] The above technical solution involves a balance detection seat used to check the balance of the drilling fixture. A smooth balance block slides freely inside the balance support. When the drilling fixture tilts, the smooth balance block slides to a lower position. A laser rangefinder detects the position of the smooth balance block and displays it via red and green indicator lights. When the smooth balance block slides to a lower position, the data detected by the laser rangefinders on a straight line differs, causing the red and green indicator lights to turn red. Moving the corresponding magnetic counterweight balances the drilling fixture, and once the drilling fixture is balanced, the smooth balance block slides to the center of the balance support. The data detected by the laser rangefinders on a straight line are now equal, causing the red and green indicator lights to turn green. This effectively adjusts the level of the drilling fixture, ensuring the stability of the drilling.

[0017] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0018] 1. A positioning chuck for engaging the high-strength drill bit and a drill bit drive seat for driving it are provided. The positions of the positioning chuck and the drill bit drive seat can be adjusted according to the drilling requirements. The positioning chuck and the drill bit drive seat allow the high-strength drill bit to switch between vertical extrusion and rotation working modes. The working mode of the high-strength drill bit can be adjusted according to the drilling requirements, thereby effectively improving the functionality of the drilling device, reducing the frequency of drilling device replacement, and improving the convenience of using the drilling device.

[0019] 2. A balance testing seat is set at the top of the drilling fixture to test the balance of the drilling device, and an adjustable magnetic counterweight is set to adjust the balance of the drilling device, which helps to ensure the stability of the drilling device and improves the convenience of using the drilling device.

[0029] Preferably, the bottom of the drilling base 1 is provided with a connecting claw platform for supporting and fixing the high-strength drill bit 2. The connecting claw platform has an installation groove for accommodating the positioning pin 3, and the high-strength drill bit 2 has a slot around its perimeter that engages with the positioning pin 3.

[0030] The above technical solution is adopted: by setting a connecting claw platform at the bottom of the drilling fixing seat 1, the high-strength drill bit 2 can be stably supported, and an installation groove is opened inside the connecting claw platform to fix the positioning pin 3, so that the slots around the high-strength drill bit 2 can be engaged with the positioning pin 3, ensuring that the drill bit can be firmly fixed and will not loosen during operation, thus ensuring the stability of the high-strength drill bit 2 during operation.

[0031] Preferably, the positioning pin 3 includes an electric telescopic rod 31 connected to the main control unit signal and a locking pin 32 for engaging the high-strength drill bit 2. The electric telescopic rod 31 is fixedly installed inside the drilling fixing base 1, and one end of the electric telescopic rod 31 is fixedly installed with the locking pin 32 that moves inside the connecting claw platform.

[0032] The above technical solution is adopted: After receiving the instruction from the main control unit, the electric telescopic rod 31 will drive the locking pin 32 to move inside the connecting claw platform. It can control the locking pin 32 to lock the high-strength drill bit 2 according to the working requirements of the high-strength drill bit 2, ensuring that the drill bit will not shift during operation and improving the drilling accuracy. Alternatively, the locking pin 32 can be moved out of the high-strength drill bit 2 to allow the high-strength drill bit 2 to rotate, which can change the working mode of the high-strength drill bit 2 and increase the diversity of drilling methods.

[0033] Preferably, in any of the above embodiments, the drilling motor 6 is fixedly installed inside the drilling mounting base 1, and the transmission gear set 5 includes a driving gear 51 and a driven gear 52 for mechanical transmission. The driving gear 51 is fixedly installed at the output end of the drilling motor 6, and the driving gear 51 meshes with the driven gear 52. The driven gear 52 and the drill bit drive base 4 are fixedly installed.

[0034] The above technical solution involves concealing the drilling motor 6 inside the drilling mounting base 1. The drilling motor 6 is controlled to output power to drive the transmission gear set 5 to transmit power as needed. The driving gear 51 transmits the power of the drilling motor 6 to the driven gear 52, which in turn drives the drill bit drive base 4 to rotate. This allows the power of the motor to be transmitted to the drill bit, making it rotate.

[0035] Preferably, in any of the above embodiments, the drill bit drive base 4 includes a drive shaft 41 for transmission, a pneumatic telescopic rod 42 for signal connection to the main control unit, and a drive block 43 for engaging the high-strength drill bit 2. The drive shaft 41 is rotatably connected to the middle of the drilling fixed base 1 and fixedly installed with the driven gear 52. The pneumatic telescopic rod 42 is fixedly installed inside the drive shaft 41, and a drive block 43 that slides on the surface of the drive shaft 41 is fixedly installed at one end of the pneumatic telescopic rod 42.

[0036] Using the above technical solution: the drive shaft 41 inside the drill bit drive seat 4 is responsible for transmitting the power output by the motor to the drive block 43, so that the drive block 43 drives the high-strength drill bit 2 to rotate. When the pneumatic telescopic rod 42 receives the signal from the main control unit, it will drive the drive block 43 to slide on the drive shaft 41. The drive block 43 can be inserted into the interior of the high-strength drill bit 2 to make the drill bit rotate, or the drive block 43 can be moved out of the high-strength drill bit 2 to make the high-strength drill bit 2 move with the drilling fixing seat 1.

[0037] Preferably, the balance detection seat 7 includes a balance support 71 for support, a smooth balance block 72 for sliding, a laser range sensor 73 for detecting the position of the smooth balance block 72, and red and green indicator lights 74 connected to the main control unit. The balance support 71 is fixedly installed on the top of the drilling fixture 1. The smooth balance block 72 that can slide freely is provided inside the balance support 71.

The red and green indicator lights 74 are fixedly installed on the top of the balance support 71, and the number of red and green indicator lights 74 is the same as the number of laser range sensors 73.

[0038] Preferably, in any of the above schemes, the magnetic counterweight 9 is movably connected to the inside of the drilling fixing base 1, and the bottom of the magnetic counterweight 9 is provided with a magnet that magnetically attracts the stainless steel plate 8.

[0039] The above technical solution is adopted: the balance detection seat 7 is used to detect whether the drilling fixture 1 is balanced. The smooth balance block 72 slides freely inside the balance support 71. When the drilling fixture 1 is tilted, the smooth balance block 72 slides to a lower position. The laser range sensor 73 detects the position of the smooth balance block 72 and then displays it through the red and green indicator lights 74. When the smooth balance block 72 slides to a lower position, the data detected by the laser range sensors 73 on the same straight line are different, and the red and green indicator lights 74 show red. The corresponding magnetic counterweight 9 is moved to balance the drilling fixture 1. After the drilling fixture 1 is balanced, the smooth balance block 72 slides to the center position of the balance support 71. The data detected by the laser range sensors 73 on the same straight line are the same, and the red and green indicator lights 74 show green. This can effectively adjust the level of the drilling fixture 1 and ensure the stability of the drilling.

[0040] The working principle of the drilling device for civil engineering pile foundations of this utility model is as follows:

[0041] Move the magnetic counterweight 9 until the red and green indicator lights 74 both turn green.
