DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0018] like Figure 1-13 As shown, a bridge pile foundation construction device comprises a main rod 1, a drill tube 2 and a connecting rod 3, the drill tube 2 is located at the bottom of the main rod 1 and is fixedly connected to the main rod 1, the main rod 1 passes through the connecting rod 3 and is movably connected to the connecting rod 3, a motor 4 is fixedly installed on one side of the top of the connecting rod 3, a group of sprockets are fixedly connected to the outside of the output shaft of the motor 4, another group of sprockets are fixedly installed on the outside of the main rod 1, the two groups of sprockets are meshed and connected with chains on the outside, and the two groups of sprockets and chains are located in the connecting rod 3, a cleaning component 5 is sleeved on the outside of the main rod 1, the cleaning component 5 comprises a connecting sleeve, two groups of positioning rods 16, a scraper 17 and three groups of sleeve rods 18, the connecting sleeve, the two groups of positioning rods 16, the scraper 17 and the three groups of sleeve rods 18 are all fixedly connected, the two groups of positioning rods 16 pass through the top of the drill tube 2, the scraper 17 is located inside the drill tube 2, three groups of bottom plates 11 are arranged at the bottom of the drill tube 2, and the three groups of sleeve rods 18 pass through the three groups of bottom plates 11 respectively.

[0019] The bottom of the three groups of bottom plates 11 are all provided with drilling teeth, and when the drill tube 2 rotates, the drilling teeth drill holes in the ground.

[0020] In this embodiment, the scraper 17 is in contact with the inner wall of the drill tube 2. A fixing rod 12 is provided inside the drill tube 2. A connecting seat 13 is provided at the bottom of the fixing rod 12. The connecting seat 13 and the three sets of bottom plates 11 are movably connected.

[0021] The scraper 17 is in close contact with the inner wall of the drill tube 2, so that the soil on the inner wall of the drill tube 2 can be scraped off, making it difficult for the inner wall of the drill tube to adhere to the soil.

[0022] In this embodiment, a plurality of water leakage grooves are provided at the upper and lower parts of the scraper plate 17 , and the fixing rod 12 passes through the center of the scraper plate 17 .

[0023] The scraper 17 can move outside the fixing rod 12, so that the movement of the scraper 17 can be more stable.

[0024] In this embodiment, a motor 2 8 is arranged above the drill tube 2, and the output shaft of the motor 2 8 is fixedly connected with a gear 1 9, and the gear 1 9 is meshingly connected with a gear 2 10, and a threaded rod 7 is arranged through the center position of the gear 2 10, and the gear 2 10 is fixedly connected to the threaded rod 7, and the threaded rod 7 is threadedly connected to the connecting sleeve of the cleaning assembly 5.

[0025] When the cleaning assembly 5 needs to be used, the motor 2 8 is started, the gear 1 9 rotates to drive the gear 2 10 to rotate, the gear 2 10 rotates to drive the threaded rod 7 to rotate, and the threaded rod 7 rotates to drive the connecting sleeve of the cleaning assembly 5 to move downward, so that the scraper 17 can also move downward. When the scraper 17 moves downward, it can push the soil inside the drill tube 2 downward.

[0026] In this embodiment, the threaded rod 7 is located at the top of the drill tube 2, and the threaded rod 7 and the drill tube 2 are movably connected.

[0027] When the cleaning assembly 5 moves downward, the sleeve rod 18 will also move downward, so that the bottom plate 11 can be opened, so that the soil inside can fall.

[0028] In this embodiment, the main rod 1 is located at the top center of the drill tube 2, and a water spray assembly 6 is arranged outside the drill tube 2. The water spray assembly 6 includes two sets of rings 23 and a plurality of water pipes 14. The two sets of rings 23 and the plurality of water pipes 14 are fixedly connected.

[0029] By providing a water spray assembly, it is convenient not only to spray water when drilling, but also to clean the inside of the drill tube 2.

[0030] In this embodiment, the main rod 1 is hollow, a water pipe 22 is provided on the inner side of the top of the drill tube 2, and a plurality of water outlets 21 are provided at the bottom of the collar 23 located below. The main rod 1, the water pipe 22, the two sets of collars 23 and the plurality of water pipes 14 are all interconnected.

[0031] In this embodiment, a short tube 15 is provided at the top of the inner side of the drill tube 2, and a plurality of water spraying grooves are provided inside and outside the short tube 15, and the main rod 1 and the short tube 15 are also connected to each other.

[0032] When it is necessary to clean the inside of the drill tube 1, the cylinder 27 is started to move the rod 25 downward in the circular groove 28, thereby blocking the end of the water pipe 22, and then the water pipe 20 is connected to the water source, and the motor 28 is started to move the scraper 17 downward. At this time, the water spray tank is opened, so the water source will spray out from the water spray tank to achieve the effect of cleaning the inside of the drill tube 2.

[0033] In this embodiment, a rotating joint 19 is provided on the top of the main rod 1 , and the main rod 1 is movably connected to a water pipe 20 via the rotating joint 19 .

[0034] When water injection and drilling are required, the water pipe 20 is connected to the water source. Since the scraper 17 blocks the water spraying groove of the short pipe 15 at this time, the water source will enter the water pipe 22 from the main rod 1 and finally spray out from the water outlet 21.

[0035] A connecting ring 24 is arranged above the collar 23, and a plurality of circular grooves 28 are opened through the top of the collar 23. A plurality of plug rods 25 are arranged at the bottom of the connecting ring 24, and the bottom of the plug rod 25 is inserted into the circular groove 28. A spring 26 is arranged outside the plug rod 25, and the top end of the spring 26 is fixedly connected to the connecting ring 24, and the bottom end of the spring 26 is fixedly connected to the collar 23. The connecting ring 24 is sleeved with the main rod 1, and a cylinder 27 is arranged on the top of the connecting ring 24, and the output shaft of the cylinder 27 is fixedly connected to the connecting ring 24, and the cylinder 27 is fixedly connected to the drill tube 2 through a mounting block.

[0036] After the inside of the drill tube 2 is cleaned, the output shaft of the cylinder 27 no longer applies pressure to the connecting ring 24, and the spring 26 is reset to drive the connecting ring 24 to move upward, so that the insertion rod 25 moves upward in the circular groove 28 and no longer blocks the end of the water pipe 22, thereby facilitating the next water injection drilling.

[0037] It should be noted that the present invention is a bridge pile foundation construction device. When in use, the height of the drill tube 2 is slowly adjusted and the motor 1 4 is started. The main rod 1 rotates to drive the drill tube 2 to rotate. A drill tooth is provided at the bottom of the drill tube 2. The drill tooth rotates to drill a hole in the ground, and the soil will be collected into the drill tube 2. After the soil inside the drill tube 2 is fully collected, the drill tube 2 is raised to separate the drill tube 2 from the hole, and the drill tube 2 is rotated to the side outside the hole to release the soil, and the motor 2 8 is started. The gear 1 9 rotates to drive the gear 2 10 to rotate, and the gear 2 10 drives the threaded rod 7 to rotate. The threaded rod 7 rotates to drive the connecting sleeve of the cleaning assembly 5 to move downward, the scraper 17 moves inside the drill tube 2, and the sleeve rod 18 moves downward. Thus, the bottom plate 11 can rotate downward, the bottom plate 11 is opened, and the soil inside the drill tube 2 will fall from the inside of the drill tube 2. The scraper 17 moves downward and can not only push the soil out of the drill tube 2, but also scrape the soil adhering to the inner wall of the drill tube 2, so that the soil will not accumulate inside the drill tube 2, which is convenient for the drill tube 2 to drill holes again and collect soil. When drilling again, the motor 2 8 is started again, the threaded rod 7 rotates, the cleaning assembly 5 moves upward, and the sleeve rod 18 also moves upward. When the cleaning assembly 5 moves, the sleeve rod 18 will drive the bottom plate 11 to rotate upward, so that the bottom plate 11 closes the bottom of the drill tube 2, and the end of the sleeve rod 18 reaches the bottom plate 11 for limiting, and then drilling can be carried out again; When water injection drilling is required, the water pipe 20 is directly connected to the external water source. Since the scraper 17 blocks the water spraying slot of the short pipe 15, the water source will flow directly through the water pipe 22 and finally spray out from the water outlet 21 at the bottom of the collar 23, so as to facilitate water injection drilling; When the inside of the drill tube 1 needs to be thoroughly cleaned, the cylinder 27 is first started, and the output shaft of the cylinder 27 moves downward to make the connecting ring 24 move downward. The connecting ring 24 drives the plug rod 25 to move downward in the circular groove 28 of the collar 23, blocking the end of the water pipe 22, and the spring 26 is compressed. Then the water pipe 20 is connected to the external water source and the cleaning component 5 is started. The cleaning component 6 moves downward, and the water spray trough leaks. At this time, since the water pipe 14 is blocked, the water source will be sprayed out from the water spray trough. At the same time, the scraper 17 moves downward, and the inside of the drill tube 2 can also be thoroughly cleaned. After cleaning, the cylinder 27 is started, so that the cylinder 27 retracts the output shaft. At this time, the spring 26 resets and drives the connecting ring 24 to move upward, so that the plug rod 25 moves upward in the circular groove 28, and the end of the water pipe 22 is no longer blocked, so that it can be convenient for the next water injection drilling.

[0038] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected.
