Description

Technical Field

[0001] The invention relates to the technical field of cement mixing piles, in particular to an auxiliary pile hanging, positioning and pressing device based on a double-axis cement mixing pile pipe pile. Background Art

[0002] Double-axis cement mixing pile is a common foundation treatment method used to increase the strength and stability of the soil. It is done by mixing cement with soil to form a solid pile body, thereby increasing the bearing capacity and anti-settlement performance of the foundation. The advantages of double-axis cement mixing pile include short construction period, stable effect, environmental protection and energy saving. It is widely used in construction, bridges, docks, water conservancy projects and other fields to treat unstable or loose soil and improve the bearing capacity and stability of the foundation.

[0003] In the existing mixing pile pipe forming process, cement is often poured into the formed hole after drilling with a drilling rod, and the soil and cement in the hole are mixed by moving the drilling rod up and down for many times. In this method, the soil is often piled at the lower end of the hole, and the cement is poured on the upper side of the soil, and the maximum uniform mixing is achieved by moving the drilling rod up and down. However, this method still cannot turn over and mix the soil at the bottom of the hole evenly, resulting in the lower end of the formed cement mixing pile often being unstable, and even sinking due to excessive weight. In addition, the existing drilling method uses a single drill rod to drill vertically, which puts a large load on the motor and the drill rod and requires a lot of power.

[0004] The existing drilling length is determined by the movement of the moving seat controlled by the system to determine the drilling depth of the drill rod. However, due to different environments, the horizontal plane height at the upper end of the borehole is often different, resulting in an error between the theoretical length and the actual length of the borehole. The length of the borehole cannot be accurately controlled, affecting the subsequent forming process of the mixing pile.

[0005] To this end, the present invention provides a device for auxiliary pile hanging, positioning and pressing based on a double-axis cement mixing pile pipe pile to solve the above-mentioned problem. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides an auxiliary pile hanging, positioning and pile pressing device based on a double-axis cement mixing pile pipe pile, which solves the above problems.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a device for positioning and pressing piles based on a pipe pile auxiliary hanging of a double-axis cement mixing pile, comprising a column and a horizontal seat arranged at the lower end of the column, a stabilizing foot is arranged laterally at the lower end of the horizontal seat, a moving seat is slidably arranged on the side wall of the column, a servo motor is fixedly arranged at the end of the moving seat, an electric telescopic cylinder is connected to the lower end of the servo motor, a limiting eccentric wheel is fixedly arranged at the lower side wall of the electric telescopic cylinder, a bearing plate is rotatably arranged below the servo motor, a limiting groove matching the electric telescopic cylinder is opened on the upper wall of the bearing plate, four connecting columns are fixedly arranged at the lower wall of the bearing plate, and a connecting steel sheet is commonly arranged at the lower end of the four connecting columns, connecting rods are rotatably arranged on the lower walls of both sides of the connecting steel sheet, and a drill rod is fixedly arranged at the lower end of the two connecting rods, and scale lines are vertically and evenly engraved on the side wall of the drill rod for observing the actual drilling depth of the drill rod, and an intermediate gear is meshed between the power gears, and the upper wall of the intermediate gear is fixedly connected to the lower end of the electric telescopic cylinder;

[0008] A casting box is provided between the upper walls of the two stabilizing legs. The casting box is annular, and the inner ring diameter of the casting box is larger than the outermost ring rotation diameter of the two drill rods. A mud storage cavity is provided in the casting box. Two connecting ports are provided on the lower end side wall of the mud storage cavity, and elastic sealing components are provided in the two connecting ports.

[0009] Preferably, a fixed connecting plate is fixedly provided on the side wall of the movable seat, a fixed ring is fixedly provided at the end of the fixed connecting plate, and the bearing plate is limitedly rotated in the ring of the fixed ring.

[0010] Preferably, the two communication ports are respectively arranged on both sides of the mud storage cavity, and the two communication ports are both opened at the inner side wall of the ring body of the casting box.

[0011] Preferably: the elastic sealing assembly includes a sliding baffle slidably arranged at the connecting port, and a spring cavity is connected and opened at the side walls on both sides of the sliding baffle. The spring cavity and the sliding baffle correspond to each other, and three return springs are fixedly arranged between the inner side wall of the spring cavity and the side wall of the sliding baffle.

[0012] Preferably, a fixing block is fixedly provided on the side wall of the sliding baffle, a backing plate is provided on the outer side wall of the fixing block, and the fixing block and the backing plate are elastically connected via a torsion spring.

[0013] Preferably, two elastic plates are fixedly provided on the inner side wall of the casting box, and a plurality of mud removal tips are elastically and telescopically provided on the side wall of the elastic plate.

[0014] Preferably, the lower end side wall of the electric telescopic cylinder and the limiting eccentric wheel are integrally formed and connected. Beneficial Effects

[0015] The present invention provides a device for auxiliary pile hanging, positioning and pressing based on a double-axis cement mixing pile pipe pile. Compared with the prior art, it has the following beneficial effects:

[0016] (1) The device for assisted pile positioning and pressing based on dual-axis cement mixing pile pipe piles first completes the drilling process in one direction, then controls the electric telescopic cylinder to run and extend, so that the limit eccentric wheel is inserted into the limit groove, controls the servo motor to drive the electric telescopic cylinder to rotate, thereby causing the two drill rods to rotate, then controls the electric telescopic cylinder to return to its original position, that is, the limit eccentric wheel and the limit groove are separated again, and drilling in different directions can be completed. At the same time, the four holes are distributed in a four-leaf clover shape, and then the drill rod rotates around the electric telescopic cylinder to mix the four holes into a large borehole. Compared with the traditional single-drill rod drilling, the workload of the drill rod is reduced, the required high-load motor power is reduced, and this method effectively reduces the possibility of collapse in the borehole during the drilling process.

[0017] (2) The device for positioning and pressing piles based on the auxiliary pile hanging of the double-axis cement mixing pile pipe is such that as the drill rod rotates, the movable seat gradually moves upward, driving the drill rod to rotate and rise at the same time, and at the same time, the mud and the added cement are evenly mixed to form a mixing pipe pile. Compared with the transmission mixing pipe pile formation method, this method can intermittently add cement into the drill hole. With the gradual rise of the drill rod, the cement content of the mixing pipe pile at each height can be similar, ensuring the uniform quality of the mixing pipe pile. The continuous increase in the height of the uniform quality pipe pile can achieve the technical effect of pressing the pipe piles below, and effectively prevent the pipe piles from being severely deformed, which is more conducive to the stability and firmness of the mixing pipe piles.

[0018] (3) The device for positioning and pressing piles based on the auxiliary lifting piles of the dual-axis cement mixing pile pipe piles determines the theoretical depth of the drill hole by controlling the movement of the moving seat during the two drilling processes. In order to understand the error between the theoretical depth and the actual depth, the actual drilling height can be observed through the scale lines on the side wall of the drill pipe, and then the movement distance of the moving seat controlled by the system can be adjusted according to the error. That is, the difference between the actual drilling length and the theoretical drilling length can be solved by eliminating the error, thereby making the drilling length more accurate.

The lower ends of the two connecting rods 17 are fixed with drill rods 8. The side walls of the drill rod 8 are vertically and evenly engraved with scale lines. The theoretical depth of the hole drilled by the drill rod 8 is determined by controlling the movement of the moving seat 4 by the system. In order to understand the error between the theoretical depth and the actual depth, the actual drilling height can be observed through the scale lines on the side walls of the drill rod 8, and then the moving distance of the moving seat 4 controlled by the system is adjusted according to the error, that is, the gap between the actual drilling depth and the theoretical drilling depth is solved by eliminating the error, and the actual drilling depth of the drill rod 8 is observed. An intermediate gear 15 is also meshed between the power gears 16, and the upper wall of the intermediate gear 15 is fixedly connected to the lower end of the electric telescopic cylinder 6;

[0031] A casting box 9 is provided between the upper walls of the two stabilizing feet 3. The casting box 9 is annular, and the inner diameter of the casting box 9 is larger than the outermost rotation diameter of the two drill rods 8. A mud storage chamber 10 is provided in the casting box 9. Two connecting ports 20 are provided at the lower end side wall of the mud storage chamber 10. Both connecting ports 20 are provided with elastic sealing components. First, the punching process in one direction is completed, and then the moving seat 4 moves upward. The signal controls the electric telescopic cylinder 6 to operate and extend, so that the limiting eccentric wheel 13 is inserted into the limiting groove 14. At this time, the intermediate gear 15 and the power gear 16 are separated from each other, and the signal controls the servo motor 5 to drive the electric telescopic cylinder 6 to rotate 90 degrees, so that the two Each drill rod 8 rotates 90 degrees, and then the signal controls the electric telescopic cylinder 6 to return to its original position, that is, the limiting eccentric wheel 13 and the limiting groove 14 are separated again, and the intermediate gear 15 and the power gear 16 are re-engaged. At this time, the above-mentioned drilling process is repeated to complete the drilling in different directions. At the same time, the four holes are distributed in a four-leaf clover shape. Then, the drill rod 8 rotates around the electric telescopic cylinder 6 to stir the four holes into a large drilled hole. Compared with the traditional single drill rod drilling, the workload of the drill rod 8 is reduced, the required high-load motor power is reduced, and this method effectively reduces the possible collapse in the drilled hole during the drilling process. Example

[0032] See also Figure 6-8 This embodiment provides a technical solution based on the first embodiment:

[0033] In an optional embodiment: a fixed connecting plate 11 is fixedly provided on the side wall of the movable seat 4 , a fixed ring 12 is fixedly provided at the end of the fixed connecting plate 11 , and the bearing plate 7 is limitedly rotated in the ring of the fixed ring 12 .

[0034] It should be noted that while the bearing plate 7 rotates below the servo motor 5 , it can obtain structural support from the fixed connecting plate 11 and the fixed ring 12 , so that the bearing plate 7 can always be supported and limited in its rotational position as the movable seat 4 moves downward.

[0035] In an optional embodiment, two communication ports 20 are respectively provided on both sides of the mud storage chamber 10 , and both communication ports 20 are opened at the inner side wall of the ring body of the casting box 9 .

[0036] It should be noted that the cement in the mud storage chamber 10 can evenly enter the position where the mixing pile needs to be cast through the connecting port 20, and prevent the connecting ports 20 from being close to each other, so that the cement entering the hole is uneven, thereby affecting the construction efficiency and quality of the mixing pile.

[0037] In an optional embodiment: the elastic sealing assembly includes a sliding baffle 21 slidably arranged at the connecting port 20, and a spring cavity 25 is connected and opened at the side walls on both sides of the sliding baffle 21, the spring cavity 25 corresponds to the sliding baffle 21, and three return springs 26 are fixedly arranged between the inner side walls of the spring cavity 25 and the side walls of the sliding baffle 21, a fixed block 22 is also fixedly arranged at the side wall of the sliding baffle 21, a back plate 23 is arranged at the outer side wall of the fixed block 22, and the fixed block 22 and the back plate 23 are elastically connected by a torsion spring 24.

[0038] It should be noted that, through the elastic sealing assembly, when the two drill rods 8 rotate around the electric telescopic cylinder 6 after drilling, the drill rod 8 pushes the plate 23 to rotate when passing through the plate 23, so that the plate 23 can drive the sliding baffle 21 to move, thereby pushing one end of the sliding baffle 21 into the spring cavity 25, and the cement stored in the mud storage cavity 10 can flow into the drilled hole through the opening between the other end of the sliding baffle 21 and the connecting port 20. With the rotation of the drill rod 8, the cement entering the hole and the mud and sand in the hole can be evenly and thoroughly mixed. As the drill rod 8 continues to rotate, until the plate 23 is pushed and rotated, the torsion spring 24 is deformed, so that the drill rod 8 can leave the plate 23, and under the action of the torsion spring 24, the side walls of the fixed block 22 and the plate 23 are realigned, and the above process can be repeated through the rotation of the drill rod 8.

[0039] As the drill rod 8 continues to rotate, the sliding baffle 21 is pushed to move to the extreme position, and the support plate 23 rotates, so that the drill rod 8 and the support plate 23 are separated from each other. Under the action of the reset spring 26, the sliding baffle 21 re-seals the connecting port 20 to wait for the next grouting process, and the torsion spring 24 can twist the support plate 23 to be on the same plane with the fixed block 22. As the drill rod 8 rotates, the moving seat 4 gradually moves up, driving the drill rod 8 to rotate and rise, and at the same time, the mud and the added cement are evenly mixed to form a mixing pipe pile. Compared with the transmission mixing pipe pile formation method, this method can intermittently add cement to the borehole, and with the gradual rise of the drill rod 8, the cement content of the mixing pipe pile at each height can be similar, ensuring the uniform quality of the mixing pipe pile, which is more conducive to the stability and firmness of the mixing pipe pile.

[0040] In an optional embodiment: two elastic plates are fixedly provided on the inner side wall of the casting box 9, and a plurality of mud removal tips are elastically and telescopically provided on the side wall of the elastic plate.

[0041] It should be noted that when the drill rod 8 passes through the surface of the elastic plate, the mud and sand on the side wall of the drill rod 8 can be scraped off by the mud removal tip. At the same time, the elastic connection between the mud removal tip and the elastic plate can effectively prevent damage to the mud removal tip or the drill rod 8 body caused by direct impact, thereby ensuring the normal use of the device structure.

[0042] In an optional embodiment: the lower end side wall of the electric telescopic cylinder 6 and the limiting eccentric wheel 13 are integrally formed and connected.

[0043] It should be noted that when the limiting eccentric wheel 13 is clamped in the limiting groove 14 and rotates with the electric telescopic cylinder 6 , the limiting eccentric wheel 13 and the electric telescopic cylinder 6 are effectively prevented from falling off.

[0044] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0045] In this case, there are controllable electromagnetic brakes between the servo motor 5 and the electric telescopic cylinder 6, and between the connecting rod 17 and the connecting steel sheet 18, that is, it is difficult for them to rotate by themselves without external power.

[0046] First, the device is moved to the desired position, and then the servo motor 5 is positioned by hoisting and hoisted above the desired hole. When the device is in use, it is divided into two processes: drilling and stirring:

[0047] When drilling, follow the instructions Fig. 9As shown in , firstly, the servo motor 5 is operated. At this time, the limit eccentric wheel 13 is above the limit slot 14 and is not engaged with each other. The servo motor 5 drives the electric telescopic cylinder 6 to rotate, thereby driving the intermediate gear 15 to rotate, and the power gears 16 meshing with each other on both sides rotate accordingly, so that the drill rod 8 fixedly connected to the power gear 16 rotates, and at the same time, the electrically controlled moving seat 4 moves downward, first completing the drilling process in one direction, and then the moving seat 4 moves upward, and the signal controls the electric telescopic cylinder 6 to operate and extend, so that the limit eccentric wheel 13 is engaged in the limit slot 14. At this time, the intermediate gear 15 and the power gear 16 are separated from each other, and the signal controls the servo motor 5 to drive the electric telescopic cylinder 6 to rotate. The electric telescopic cylinder 6 is then controlled by the signal to return to its original position, that is, the limiting eccentric wheel 13 and the limiting groove 14 are separated again, and the intermediate gear 15 and the power gear 16 are re-engaged. At this time, the above-mentioned drilling process is repeated to complete the drilling in different directions. At the same time, the four holes are distributed in a four-leaf clover shape. Then, the four holes are stirred into a large borehole by the rotation of the drill rod 8 around the electric telescopic cylinder 6. Compared with the drilling of a traditional single drill rod, the workload of the drill rod 8 is reduced, the required high-load motor power is reduced, and this method effectively reduces the possible collapse of the borehole during the drilling process.

[0048] During the two drilling processes, the system controls the movement of the moving seat 4 to determine the theoretical depth of the drilling rod 8. In order to understand the error between the theoretical depth and the actual depth, the actual drilling height can be observed through the scale lines on the side wall of the drilling rod 8, and then the moving distance of the system-controlled moving seat 4 can be adjusted according to the error, that is, the gap between the actual drilling depth and the theoretical drilling depth can be solved by eliminating the error.

[0049] When stirring is performed, the drill rod 8 for the second drilling is in the hole, and the signal controls the electric telescopic cylinder 6 to run and extend, so that the limit eccentric wheel 13 is inserted into the limit groove 14, and the intermediate gear 15 and the power gear 16 are separated from each other. At this time, the servo motor 5 is controlled to run, driving the two drill rods 8 to rotate slowly with the electric telescopic cylinder 6 as the axis, so that the four holes and the thin-walled mud columns between the holes are pushed down and stirring is performed in the holes. It should be noted that the part between the four holes naturally collapses due to the adhesion between the soil and the rotation of the drill rod 8 around the electric telescopic cylinder 6 during stirring, so that the four holes are merged into a large borehole;

[0050] During stirring, in cooperation with the two drill rods 8 rotating around the electric telescopic cylinder 6, when the drill rod 8 slowly rotates and contacts with the butt plate 23, the butt plate 23, the fixed block 22 and the sliding baffle 21 are pushed to move together, and the sliding baffle 21 is pushed in the connecting port 20, and the return spring 26 in the spring chamber 25 is compressed, so that an outlet is generated between the connecting port 20 and the sliding baffle 21, and the cement stored in the mud storage chamber 10 can fall into the drill hole, and in cooperation with the stirring of the drill rod 8, the mud and sand are mixed with the cement to form a mixing pipe pile. As the drill rod 8 continues to rotate, the sliding baffle 21 is pushed to move to the extreme position, and the butt plate 23 rotates, so that the drill rod 8 and the butt plate 23 are separated from each other. Under the action of the return spring 26, the sliding baffle 21 re-closes the connecting port 20 0 is sealed to wait for the next grouting process, and the torsion spring 24 can twist the plate 23 to be on the same plane with the fixed block 22 again. As the drill rod 8 rotates, the movable seat 4 gradually moves up, driving the drill rod 8 to rotate and rise at the same time, and at the same time, the mud and the added cement are evenly mixed to form a mixing pipe pile. Compared with the transmission mixing pipe pile formation method, this method can intermittently add cement to the borehole, and with the gradual rise of the drill rod 8, the cement content of the mixing pipe pile at each height can be similar, ensuring the uniform quality of the mixing pipe pile. The continuous increase in the height of the uniform quality pipe pile can achieve the technical effect of pressing the piles below, and effectively prevent the pipe piles from being severely deformed, which is more conducive to the stability and firmness of the mixing pipe piles.
