DETAILED DESCRIPTION

[0020] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0021] like Figure 1-Figure 9As shown, an automatic pile-forming equipment suitable for cement-soil composite piles includes a fixed plate 3, a spiral rod 1 and a grouting pipe 2. A disc 4 is provided on the left side of the fixed plate 3. The spiral rod 1 and the grouting pipe 2 are respectively connected to the disc 4 in a transmission manner. The spiral rod 1 and the grouting pipe 2 are arranged below the disc 4 so that the spiral rod 1 and the grouting pipe 2 can be used at intervals. The pile hole is first driven by the spiral rod 1, and then the grouting pipe 2 is placed in the pile hole for grouting, so as to avoid blockage of the grouting pipe 2.

[0022] When in use, it is necessary to first fix the fixed slide rail 30 in the construction area so that the fixed plate 3 can move freely. Specifically, a plurality of fourth telescopic devices 28 (the fourth telescopic device 28 is a fourth hydraulic telescopic rod) are fixedly provided at the bottom of the fixed plate 3. A sliding sleeve 29 is fixedly provided at the bottom of the fourth telescopic device 28. The fourth telescopic device 28 can adjust the height of the fixed plate 3. When reaching the construction area, the fourth telescopic device 28 can be used to make the bottom of the second lead screw 19 and the second light rod 20 stop against the ground, thereby improving stability and avoiding shaking during drilling or grouting.

[0023] The sliding sleeve 29 is slidably mounted on the fixed rail 30, and the fixed rail 30 is fixed on the ground. The fixed rail 30 and the sliding sleeve 29 cooperate with each other to drive the fixed plate 3 to move along the extension direction of the fixed rail 30. A driving motor is provided inside the sliding sleeve 29, and a rolling wheel is fixed on the output shaft of the driving motor, so that the driving motor can drive the rolling wheel to rotate after it is started. When the rolling wheel rotates, it can drive the sliding sleeve 29 to slide along the fixed rail 30, thereby driving the fixed plate 3 to move, so as to adjust the position of the fixed plate 3 for easy operation.

[0024] By setting the multi-section telescopic rod mechanism 6, column cores can be inserted into multiple pile holes at the same time. Specifically, an L-shaped connecting plate 5 is provided below the fixed plate 3, and a multi-section telescopic rod mechanism 6 (the multi-section telescopic rod mechanism 6 is a multi-section electric push rod) extending in the left-right direction is fixedly provided on the right side of the L-shaped connecting plate 5. The multi-section telescopic rod mechanism 6 is provided with a plurality of first driving devices 7 (the first driving device 7 is a first driving self-locking motor) extending in the left-right direction, and a clamping limit mechanism 8 is provided on the output shaft of the first driving device 7. The multi-section telescopic rod mechanism 6 is provided with a plurality of first cameras, which can observe the clamping situation of the clamping limit mechanism 8. The clamping limit mechanism 8 is used to clamp the column core and insert it into the pile hole. The first driving device 7 is driven to start, so that the output shaft of the first driving device 7 can drive the clamping limit mechanism 8 to rotate, so that the column core can be clamped in the clamping limit mechanism 8.

[0025] The multi-section telescopic rod mechanism 6 is used to drive the plurality of first driving devices 7 to evenly telescope in the left-right direction.

[0026] The column core can be clamped by the clamping and limiting mechanism 8 so that the column core can be inserted into the piling hole, thereby improving the stability of the pile body. Specifically, the clamping and limiting mechanism 8 includes a fixed frame 801, a clamping member 802 and a third drive device 803 (the third drive device 803 is a third drive self-locking motor). There are two clamping members 802 and they are spaced apart. The initial state of the clamping and limiting mechanism 8 is a vertical state contracted in the L-shaped connecting plate 5, so that when the L-shaped connecting plate 5 rotates, the clamping and limiting mechanism 8 will not contact the fourth telescopic device 28.

[0027] The front side of the fixed frame 801 is fixed on the output shaft of the first driving device 7. When the multi-section telescopic rod mechanism 6 is extended, the fixed frame 801 is also driven by the first driving device 7 to flip into a horizontal state so as to clamp the limiting column core. The left and right sides of the fixed frame 801 are respectively hingedly connected with the first connecting rod 14, and the left and right sides of the clamping member 802 are both hingedly connected with the first connecting rod 14. When the clamping member 802 rotates, the first connecting rod 14 also rotates accordingly.

[0028] The third driving device 803 is fixed on the fixed frame 801, and the output shaft of the third driving device 803 is fixedly provided with a first gear 15. One side of the fixed frame 801 is rotatably provided with two gear rods 16 spaced up and down (the gear rod 16 is formed by a gear and a short rod fixedly connected). The two gear rods 16 are meshed with each other, and the first gear 15 is meshed with one of the gear rods 16. The front side of the clamping member 802 is hingedly connected to the front side of the gear rod 16, and the third driving device 803 is driven to start, so that the output shaft of the third driving device 803 drives the first gear 15 to rotate. Since the first gear 15 is meshed with one of the gear rods 16, it can drive one of the gear rods 16 to rotate. Since the two gear rods 16 are meshed with each other, they can drive the other gear rod 16 to rotate, so that the two gear rods 16 rotate in opposite or opposite directions.

[0029] When the two gear rods 16 rotate, they can drive the two clamping members 802 to move toward or away from each other, thereby clamping the column core to limit the column core.

[0030] The direction of the multi-section telescopic rod mechanism 6 can be changed by the steering mechanism 9 so as to extend it in different directions, thereby inserting the column core into the pile holes in different directions. Specifically, a steering mechanism 9 is provided above the L-shaped connecting plate 5, and the steering mechanism 9 is used to adjust the direction of the L-shaped connecting plate 5.

[0031] The steering mechanism 9 includes a second driving device 901 (the second driving device 901 is a second driving self-locking motor), a rotating plate 902 and a first telescopic device 903 extending in the up-down direction (the first telescopic device 903 is a first hydraulic telescopic rod).

[0032] The second driving device 901 is fixedly arranged at the bottom of the fixed plate 3, and the output shaft of the second driving device 901 is fixedly connected to the top of the rotating plate 902. The second driving device 901 is driven to start, so that the output shaft of the second driving device 901 can drive the rotating plate 902 to rotate, thereby changing the direction of the multi-section telescopic rod mechanism 6. A limiting groove 10 extending along the extension direction of the rotating plate 902 and opening downward is provided at the bottom of the rotating plate 902, and the cross-sectional shape of the limiting groove 10 is an inverted convex structure.

[0033] A slider 11 is fixedly provided on the top of the fixed rod of the first telescopic device 903, and the slider 11 is slidably arranged in the limit groove 10. The bottom of the movable rod of the first telescopic device 903 is fixedly arranged on the top of the L-shaped connecting plate 5. When the clamping and limiting mechanism 8 clamps the column core, the first telescopic device 903 is driven to start, so that the clamping and limiting mechanism 8 drives the column core to move downward together, so that the column core can be inserted into the pile hole.

[0034] A first lead screw 12 extending in the left-right direction is rotatably provided in the limiting groove 10, and a tenth driving device 13 (the tenth driving device 13 is a tenth driving self-locking motor) is fixedly provided on the left side of the rotating plate 902. The output shaft of the tenth driving device 13 passes through the rotating plate 902 and is fixedly connected to the first lead screw 12. The tenth driving device 13 is driven to start, so that the output shaft of the tenth driving device 13 drives the first lead screw 12 to rotate. When the first lead screw 12 rotates, it can drive the slider 11 to move along the limiting groove 10, thereby pushing the L-shaped connecting plate 5 out of the fixed plate 3, which is convenient for the extension and storage of the multi-section telescopic rod mechanism 6.

[0035] When the first lead screw 12 rotates, it drives the slider 11 to move along the extending direction of the limiting groove 10 .

[0036] By opening the annular sliding groove 17, the hanging plate 18 can slide along the annular sliding groove 17 so as to adjust the position of the hanging plate 18. Specifically, an annular sliding groove 17 is opened on the peripheral side surface of the fixed plate 3, and the top of the disc 4 is rotatably provided with a hanging plate 18. The right side of the hanging plate 18 is slidably arranged in the annular sliding groove 17. A mobile driving mechanism is provided on the hanging plate 18. The mobile driving mechanism is used to drive the hanging plate 18 to move along the annular sliding groove 17. The mobile driving mechanism includes two seventh driving motors spaced apart from each other and a plurality of traveling wheels, wherein two traveling wheels are fixedly connected to the output shaft of the seventh driving motor, and the seventh driving motor is driven to start, so that the seventh driving motor can drive the traveling wheel to rotate, and the traveling wheel can move along the annular sliding groove 17 when rotating.

[0037] A sixth drive device 31 (the sixth drive device 31 is a sixth drive self-locking motor) is fixedly provided on the top of the suspension plate 18. The output shaft of the sixth drive device 31 passes through the suspension plate 18 and is fixedly connected to the disc 4. The sixth drive device 31 is driven to start, so that the output shaft of the sixth drive device 31 drives the disc 4 to rotate, so that the spiral rod 1 and the grouting pipe 2 can be switched for use, so that the spiral rod 1 and the grouting pipe 2 do not affect each other.

[0038] A second camera is provided in the middle of the bottom of the disc 4 , which can penetrate the situation of the spiral rod 1 or the grouting pipe 2 .

[0039] The bottom of the disc 4 is provided with two second lead screws 19 and a second polished rod 20 spaced apart from each other and extending in the up-down direction.

[0040] A fourth drive device 21 (the fourth drive device 21 is a fourth drive self-locking motor) is fixedly provided on the top of one of the second lead screws 19. The top of the fourth drive device 21 is fixedly provided at the bottom of the disc 4. The fourth drive device 21 is driven to start, so that the output shaft of the fourth drive device 21 drives one of the second lead screws 19 to rotate. When the second lead screw 19 rotates, it can drive the left lifting plate 22 and the right lifting plate 23 to move up and down along the second light rod 20. The other second lead screw 19 is rotatably provided at the bottom of the disc 4. Sprockets 24 are fixedly provided on the two second lead screws 19. The two sprockets 24 are connected to each other by a chain. Through the mutual cooperation of the sprocket 24 and the chain, the other second lead screw 19 can be driven to rotate, so that the left lifting plate 22 and the right lifting plate 23 move toward each other or away from each other.

[0041] A left lifting plate 22 and a right lifting plate 23 are provided below the disc 4. The left lifting plate 22 and the right lifting plate 23 are respectively mounted on the corresponding second lead screw 19 and the second light rod 20, and the left lifting plate 22 and the right lifting plate 23 are threadedly connected to the second lead screw 19. When the left lifting plate 22 moves downward, the right lifting plate 23 moves upward.

[0042] When the two second lead screws 19 rotate, they are used to drive the left lifting plate 22 and the right lifting plate 23 to move in opposite directions or in opposite directions.

[0043] The left lifting plate 22 is provided with a punching mechanism for drilling pile holes, and the right lifting plate 23 is provided with a grouting mechanism for pouring grout.

[0044] The punching mechanism includes a fifth driving device 25 (the fifth driving device 25 is a fifth driving self-locking motor) fixedly arranged on the top of the left lifting plate 22 , and the top of the fifth driving device 25 is lower than the bottom of the disc 4 .

[0045] The output shaft of the fifth driving device 25 passes through the left lifting plate 22 and is fixedly connected to the screw rod 1, driving the fifth driving device 25 to start. When the fifth driving device 25 rotates, it can drive the screw rod 1 to rotate so as to perform drilling.

[0046] The grouting mechanism includes a slurry box 26 fixed on the top of the right lifting plate 23. The top of the slurry box 26 is lower than the bottom of the disc 4. When the left lifting plate 22 is raised, the right lifting plate 23 moves downward. However, since a pump is provided in the slurry box 26, the slurry can be transported to the drilled hole through the grouting pipe 2.

[0047] The grouting mechanism passes through the bottom of the right lifting plate 23 and is fixedly connected to the grouting pipe 2 .

[0048] Because the first camera and the second camera are interconnected with the controller, and the controller is connected to a display screen, the construction workers only need to observe the display screen to realize pile forming without manual operation, and the fourth telescopic device 28, the multi-section telescopic rod mechanism 6, the first drive device 7, the third drive device 803, the second drive device 901, the first telescopic device 903, the tenth drive device 13, the sixth drive device 31, the fourth drive device 21, the fifth drive device 25, the driving motor and the seventh drive motor are all interconnected with the controller, so the operation can be performed through the controller, which plays a simple and convenient role.

[0049] Working principle: construction personnel operate the controller to control the start-up of the driving mobile motor, so that a rolling wheel is fixed on the output shaft of the driving mobile motor, so that after the driving mobile motor is started, it can drive the rolling wheel to rotate, and when the rolling wheel rotates, it can drive the sliding sleeve 29 to slide along the fixed slide rail 30, and then drive the fixed plate 3 to move, so as to adjust the position of the fixed plate 3, and stop when it reaches the construction area.

[0050] Then, the seventh drive motor is driven so that the seventh drive motor can drive the traveling wheel to rotate. When the traveling wheel rotates, it can move along the annular sliding groove 17 to adjust the position of the suspension plate 18. When the screw rod 1 is located directly above the hole to be punched, it stops. Then, the fourth drive device 21 is driven to start, so that the output shaft of the fourth drive device 21 drives one of the second lead screws 19 to rotate. When the second lead screw 19 rotates, it can drive the left lifting plate 22 to move downward, and at the same time, the right lifting plate 23 moves upward.

[0051] The fifth driving device 25 is driven to start. When the fifth driving device 25 rotates, it can drive the screw rod 1 to rotate so as to perform drilling. After the pile hole is drilled, the sixth driving device 31 is started to drive so that the output shaft of the sixth driving device 31 drives the disc 4 to rotate so that the screw rod 1 and the grouting pipe 2 can be switched for use. Then the fourth driving device 21 is driven to start so that the output shaft of the fourth driving device 21 drives one of the second lead screws 19 to rotate. When the second lead screw 19 rotates, it can drive the left lifting plate 22 to move upward, and at the same time the right lifting plate 23 moves downward. By grouting the pile holes, the construction workers can observe the drilling and grouting conditions through the second camera.

[0052] After a plurality of pile holes are drilled, while the screw rod 1 continues to work, the construction worker can operate the controller to start the second drive device 901 so that the output shaft of the second drive device 901 can drive the rotating plate 902 to rotate, thereby changing the direction of the multi-section telescopic rod mechanism 6.

[0053] After the orientation is set, the multi-section telescopic rod mechanism 6 is driven to start, driving the multiple clamping and limiting mechanisms 8 to extend evenly. During the extension process, the fixed frame 801 is driven to flip into a horizontal state through the first driving device 7 so as to clamp the limiting column core. Then, the multiple column cores are placed in the clamping and limiting mechanisms 8 respectively, and the third driving device 803 is driven to start, so that the output shaft of the third driving device 803 drives the first gear 15 to rotate. Since the first gear 15 is meshed with one of the gear rods 16, it can drive one of the gear rods 16 to rotate. Since the two gear rods 16 are meshed with each other, the other gear rod 16 can be driven to rotate, forming the two gear rods 16 rotating in opposite or opposite directions. When the two gear rods 16 rotate, they can drive the clamping member 802 to move in opposite or opposite directions, thereby clamping the column core to limit the column core.

[0054] After clamping the column core, the first telescopic device 903 is driven to start, so that the clamping limit mechanism 8 drives the column core to move downward together, so that multiple column cores can be inserted into the pile hole, thereby facilitating operation. The clamping condition of the clamping limit mechanism 8 can be observed through the first camera.

[0055] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is limited by the appended claims rather than the above description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
