Technical Field

[0001] The utility model relates to the technical field of drilling devices, and more specifically, to a bridge pile foundation drilling device. Background Art

[0002] Before a bridge is built, it is necessary to first build a bridge pile foundation. When building the bridge pile foundation, a bridge pile foundation drilling device is needed to drill holes so that the pile foundation can be built. During use, holes are drilled through a drill bit. During the use of the drill bit, the soil may stick to the drill bit due to the soil being relatively moist. When there is a lot of sticky soil, it may affect the drilling ability of the drill bit. The drill bit is large, and it is more troublesome to clean it manually, which reduces the drilling efficiency. Utility Model Content

[0009] As a preferred technical solution of the utility model, a piston cavity is opened in the middle of the tapered rod, and the piston cylinder is connected with the piston cavity through a vent pipe.

[0010] As a preferred technical solution of the utility model, the piston auxiliary rod is composed of a piston head and an insert rod, and the piston head is in contact with the inner wall of the piston cavity.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. After the drill bit has finished drilling, the utility model first drives the drill bit at the bottom end of the electric rod to vibrate through a vibration motor.

[0022] After the drill bit 7 has completed drilling, the drill bit 7 at the bottom end of the electric rod 5 is first driven to vibrate by the vibration motor 4. At this time, the drill bit 7 can vibrate stably due to the elasticity and flexibility of the spring assembly 3. At the same time, water is transported to the spray head 11 through the water pump 9, and sprayed to the surface of the drill bit 7 through the spray head 11, thereby cleaning the drill bit 7 and avoiding the situation in which the drill bit 7 is covered with too much soil on its surface during use, which affects its use.

[0023] Among them, a cylinder 12 is fixedly installed on the left side of the support frame 2, and a piston rod 13 is fixedly sleeved on the output shaft of the cylinder 12. A piston cylinder 14 is fixedly installed on the left side of the support frame 2. A vent pipe 15 is fixedly connected to the bottom end of the piston cylinder 14. A tapered rod 16 is fixedly installed on the bottom end of the vent pipe 15. A return spring 17 is fixedly installed in the inner cavity of the tapered rod 16. A piston auxiliary rod 18 is fixedly installed on the side of the return spring 17 away from the tapered rod 16.

[0024] After the tapered rod 16 at the bottom end of the installation base plate 1 is inserted into the ground, the cylinder 12 is started to drive the piston rod 13 to move in the inner cavity of the piston cylinder 14, thereby squeezing the air in the inner cavity of the piston cylinder 14, so that the air enters the inner cavity of the tapered rod 16 through the vent pipe 15, and then drives the piston auxiliary rod 18 in the inner cavity of the tapered rod 16 to extend out of the inner cavity of the tapered rod 16, thereby realizing the extension of the piston auxiliary rod 18, so that the tapered rod 16 and the piston auxiliary rod 18 form an L-shaped fixation, thereby increasing the stability of the installation base plate 1, and after use, it is only necessary to move the piston rod 13 in the inner cavity of the piston cylinder 14 to drive the piston auxiliary rod 18 to reset, which is simple and convenient, and improves the convenience of installation and disassembly of the installation base plate 1.

[0025] The bottom end of the electric rod 5 is provided with a placement cavity, and the servo motor 6 is fixedly installed inside the placement cavity;

[0026] Through the placement cavity of the electric rod 5, the servo motor 6 can be fixedly installed inside the placement cavity, so that the servo motor 6 can drive the drill bit 7 to rotate and perform drilling.

[0027] Among them, a connector 10 is fixedly installed at the input end of the water pump 9, and a spray head 11 is located on the left side of the drill bit 7;

[0028] Through the connector 10 at the input end of the water pump 9, the water source can be connected to the input end of the water pump 9 through the connector 10, so that the water pump 9 can transport water to the spray head 11, and then through the spray head 11 located on the left side of the drill bit 7, so that the water sprayed by the spray head 11 can clean the surface of the drill bit 7.

[0029] The spring assembly 3 is composed of a damping telescopic rod and a spring, and the damping telescopic rod is located at the center of the spring cavity;

[0030] By setting the spring, the vibration motor 4 can drive the drill bit 7 at the bottom end of the electric rod 5 to vibrate, and then by setting the damping telescopic rod, the electric rod 5 is positioned and guided by the damping telescopic rod to prevent the drill bit 7 at the bottom end of the electric rod 5 from shifting during the shaking process.

[0031] A piston cavity is provided in the middle of the tapered rod 16, and the piston cylinder 14 is connected to the piston cavity through a vent pipe 15;

[0032] Through the piston cavity in the middle of the tapered rod 16, the air in the inner cavity of the piston cylinder 14 can pass through the vent pipe 15 and the piston cavity, thereby driving the piston auxiliary rod 18 inside the piston cavity to move, thereby assisting in fixing the tapered rod 16 and increasing the stability of the mounting base 1.

[0033] The piston auxiliary rod 18 is composed of a piston head and an insertion rod, and the piston head fits the inner wall of the piston cavity;

[0034] The piston head fits against the inner wall of the piston cavity, so that the air output by the vent pipe 15 can stably squeeze the piston auxiliary rod 18 to move, thereby driving the insertion rod to insert into the ground squadron conical rod 16 for auxiliary support and fixation.

[0035] The working principle and use process of the utility model are as follows: first, the installation base plate 1 is moved to the designated position, then the tapered rod 16 is inserted into the ground, and then the air cylinder 12 is started to drive the piston rod 13 to move in the inner cavity of the piston cylinder 14, and the air in the inner cavity of the piston rod 13 is squeezed by the piston cylinder 14, so that the air is squeezed into the inner cavity of the tapered rod 16 through the vent pipe 15, and then the piston auxiliary rod 18 is driven to move to the outer side of the tapered rod 16, so that the piston auxiliary rod 18 is inserted into the ground;

[0036] After the fixing of the mounting base plate 1 is completed, the drill bit 7 is driven to rotate by starting the servo motor 6, and the drill bit 7 is driven to move downward along the axis direction of the electric rod 5 through the electric rod 5. When the drill bit 7 finishes drilling, the electric rod 5 drives the drill bit 7 to rise, and then through the mobility of the spring assembly 3, the vibration motor 4 is started to drive the drill bit 7 at the bottom of the electric rod 5 to shake and shake off the soil, and the water source is connected to the connector 10, and then the water pump 9 is started to transport water to the spray head 11, and the water is sprayed at high pressure to the surface of the drill bit 7 through the spray head 11 to clean the drill bit 7.
