Description

Technical Field

[0001] The present invention relates to the technical field of pile driving devices, and more specifically, to an anti-tilting pile driving device. Background Art

[0002] In the process of civil engineering construction and general structure construction, in order to further increase the firmness of the foundation or improve the structural stability, it is necessary to drive piles into the ground, and the pile driving equipment is an important facility for driving piles into the ground. The prior art document with the publication number CN209908405U provides an anti-tilting pile driving device for civil engineering that is easy to fix. This device only drills holes through the auger and then manually places the steel pile, which increases unnecessary processes and prolongs the construction period. At the same time, although it can prevent the pile from tilting during pile driving, it cannot guarantee the verticality of the pile, and tilting still occurs, resulting in unstable buildings in the later stage, posing a safety hazard, and it cannot adapt to piles of different diameters. In addition, although in CN215925969U, different diameter piles can be adapted by replacing the casing, and it can ensure that the pile remains vertical or substantially vertical during pile driving, the operation of disassembling and replacing the casing is troublesome, and multiple casings need to be configured, and it cannot be adjusted adaptively according to the pile diameter. In view of this, we propose an anti-tilting pile driving device. Summary of the Invention

[0019] 3. Beneficial effects

[0020] Compared with the prior art, the advantages of the present invention are as follows:

[0021] (1) Through the setting of the diameter-adaptive anti-tilting clamping mechanism in the present invention, after the pile is clamped, due to the arc-shaped anti-tilt groove on the anti-tilting positioning column, the pile can be vertically clamped. Before the pile reaches directly below the driving pile column, it is in a suspended state, so it will not be affected by uneven ground. At the same time, the fixed box and the driving pile column itself are in a vertical state. At this time, it can be directly knocked into the soil, ensuring the verticality of the pile and preventing it from tilting, thus guaranteeing the stability of the later building and enabling it to adapt to piles of different diameters.

[0022] (2) Through the setting of the pile positioning and driving mechanism in the present invention, during the use process, the fixed box can be driven to extend by the push rod to fix and position the pile, and then drive the pile column, avoiding the cumbersome process of drilling holes first and then placing the pile, improving the driving efficiency.

[0023] (3) In the present invention, one end of the three-claw limiting rod, the first stop rod and the second stop rod are all provided with rotating columns. An empty groove is opened in the middle of the anti-tilting positioning column, and two adjusting grooves are symmetrically opened inside the empty groove. The adjusting grooves are rotatably connected to the rotating columns. At this time, when clamping the pile, due to the clamping force, the anti-tilting positioning column adapts to the outer wall radian of the pile by changing the angle, so that a certain distance of the pile is stuck inside the arc-shaped anti-tilt groove, thus ensuring the verticality of the pile.

[0033] Please refer to Figures 1-6 The present invention provides a technical solution:

[0034] A pile driving device capable of preventing tilting, including a mobile pile driving box 1, a protective cover 2 is provided on the upper side of the mobile pile driving box 1, a pile positioning and driving mechanism with fixed piles 3 is provided on the mobile pile driving box 1, a machine box 101 is provided on one side inside the mobile pile driving box 1, a motor 102 is provided inside the machine box 101, and a rotating groove 103 is opened in the middle of the surface of the mobile pile driving box 1;

[0035] A fixed box 4 is slidably arranged through the outside inside the mobile pile driving box 1, an arc groove 401 is opened in the middle position on the outside of the fixed box 4, and a diameter-adaptive anti-tilting clamping mechanism 5 is provided inside the fixed box 4.

[0036] Specifically, the pile positioning and driving mechanism with fixed piles 3 includes an adjusting rod 301, one end of the adjusting rod 301 is rotatably connected to a V-shaped limiting plate 302, a balance rod 303 is arranged in parallel above the V-shaped limiting plate 302, and one end of the V-shaped limiting plate 302 and one end of the balance rod 303 are rotatably connected to the same pile driving support rod 304, and a pile driving column 305 is fixedly arranged on the bottom surface of the pile driving support rod 304.

[0037] The diameter-appropriate anti-tilt clamping mechanism 5 includes an opening enclosure rod 502, to which a plurality of limit bars are rotatably connected, and an anti-tilt positioning column 5011 is provided at one end of the limit bar. The plurality of limit bars are rotatably connected in sequence through a connecting rod to form a series linkage structure, wherein a telescopic rod 505 is connected to one of the limit bars, and the telescopic rod 505 is rotatably connected to the inner wall of the fixed box 4.

[0038] In this technical solution, a controller is provided on the piling device, and the fixed box 4 is driven by the controller to perform reciprocating motion inside and outside along the mobile piling box 1. When the fixed box 4 is extended, the pile is placed inside the arc groove 401, and then the telescopic rod 505 is driven to extend and retract, driving multiple limit stop rods to rotate inward synchronously and gather together, thereby forming a clamping. The anti-tilt positioning column 5011 can clamp a certain distance of the pile inside the arc anti-tilt groove 5011, thereby ensuring the verticality of the pile. After the pile is stably clamped, the fixed box 4 is controlled to be driven to be retracted, and the pile is moved to the position to be piled.

[0039] After moving into position, the telescopic adjustment rod 301 can be driven to extend, and one end of the telescopic adjustment rod is rotatably connected to the rotating groove 103, thereby driving the V-shaped limiting plate 302 to change its angle, pushing the piling support rod 304 to drive the piling column 305 to move downward to knock the pile, and a balance rod 303 is arranged parallel to the upper end of the V-shaped limiting plate 302, so that it can be limited by the balance rod 303, so that the piling column 305 can maintain a vertical state, so that the surface of one end of the pile is evenly stressed, and the verticality of the piling is further improved.

[0040] The present invention arranges the diameter-appropriate anti-tilt clamping mechanism 5 so that after clamping the pile, the pile can be vertically clamped due to the arrangement of the anti-tilt positioning column, and the pile is suspended before reaching directly below the pile driving column 305, so it will not be affected by the uneven ground. At the same time, the fixing box 4 and the pile driving column 305 itself are in a vertical state. At this time, it can be directly hammered into the soil, ensuring the verticality of the pile and preventing it from tilting, thereby ensuring the stability of the later construction and making it adaptable to columns of different diameters.

[0041] By setting the pile positioning and piling mechanism 3, during use, the fixing box 4 can be extended to fix the pile by pushing the rod 307, and then pulled back. At this time, it is just below the pile driving column 305, so that it can be directly hit once to drive the pile, avoiding the tedious process of drilling holes first and then placing piles, thereby improving the efficiency of piling. At the same time, the staff can stay away, avoiding the situation of manual placement and then hitting, which is prone to danger, so that the pile driving column 305 can accurately hit and fix the pile when hitting.

[0042] In some technical solutions, such as Figure 3As shown in the figure, a motor 102 is provided inside the movable pile driving box 1. A push rod 307 is provided on the inner side of the movable pile driving box 1. The inner end of the push rod 307 is rotatably connected to a movable rod 308. The outer end of the push rod 307 is rotatably provided with a hinge seat B309. The outer end of the movable rod 308 is coaxially connected and fixed to the output shaft of the motor 102. The hinge seat B309 is connected and fixed to the outer wall of the fixed box 4.

[0043] The output shaft of the motor 102 is driven to rotate by the controller. Since the outer end of the movable rod 308 is coaxially connected to the output shaft of the motor 102, the movable rod 308 is driven to rotate, so that the fixed box 4 can perform reciprocating motion inside and outside.

[0044] Furthermore, as Figure 2 shown in the figure, the inner end of the balance rod 303 is rotatably connected to the hole inside the protective cover 2 through a pin shaft. The middle part of the V-shaped limiting plate 302 is rotatably connected to the hole inside the protective cover 2 through a pin shaft.

[0045] In the present invention, by the arrangement that the balance rod 303 and the V-shaped limiting plate 302 are rotatably connected to the holes inside the protective cover 2, the pile driving column 305 can move up and down.

[0046] Still further, the outer end of the balance rod 303 is rotatably connected to the upper end of the pile driving support rod 304 through a pin shaft. When the pile driving column 305 is at the knocking limit position, it is in a straight line with the center of the arc of the arc-shaped groove 401.

[0047] In the present invention, by the pile driving column 305 being in a straight line with the center of the arc of the arc-shaped groove 401, the pile driving column 305 can accurately knock and fix the pile when knocking.

[0048] In some technical solutions, fixing blocks 306 are fixedly provided at both ends of the telescopic adjusting rod 301. The outer end of the telescopic adjusting rod 301 is rotatably connected to the V-shaped limiting plate 302 through the fixing block 306. One end of the telescopic adjusting rod 301 is rotatably connected to the rotating groove 103 through the fixing block 306 to improve the rotating effect of the telescopic adjusting rod 301.

[0049] In this embodiment, a further refined design of the diameter-adaptive anti-tilting clamping mechanism 5 is carried out. Combining Figures 4 to 6Looking at it, the diameter-adaptable anti-tilting clamping mechanism 5 further includes a V-shaped control rod 501. An opening surrounding rod 502 is fixedly provided at the outer end of the V-shaped control rod 501. The opening surrounding rod 502 is fixedly provided with a plurality of fixing columns 503 in a triangular structure. A three-claw limiting rod 504 is rotatably arranged in the middle of the opening surrounding rod 502 through the fixing columns 503. An expansion rod 505 is arranged inside the V-shaped control rod 501. One end of the expansion rod 505 is provided with a rotating seat A 506, and the other end of the expansion rod 505 is provided with a rotating seat B 507. A first blocking rod 508 is rotatably arranged at one end of the opening surrounding rod 502, and a second blocking rod 509 is rotatably arranged at the other end of the opening surrounding rod 502. Two connecting rods 5010 are symmetrically rotatably arranged on the outer side of the three-claw limiting rod 504 through pin shafts. The outer end of one of the connecting rods 5010 is rotatably connected to the outer end of the first blocking rod 508 through a pin shaft, and the outer end of the other connecting rod 5010 is rotatably connected to the outer end of the second blocking rod 509 through a pin shaft. A plurality of anti-tilting positioning columns 5011 are arranged at equal intervals in a ring inside the opening surrounding rod 502. A plurality of arc-shaped anti-tilt grooves 5012 are arranged at equal intervals in a ring on the circumferential outer wall of the anti-tilting positioning column 5011.

[0050] Through the setting of the diameter-adaptable anti-tilting clamping mechanism 5 of the present invention, after the pile is clamped, due to the setting of the arc-shaped anti-tilt grooves 5012 on the anti-tilting positioning columns 5011, the pile can be vertically clamped. The expansion and contraction of the driving rod 505 drives the change of the angle of the three-claw limiting rod 504. And due to the change of the angle of the three-claw limiting rod 504, and the connecting rods 5010 are all rotatably connected to the three-claw limiting rod 504, the angles of the second blocking rod 509 and the first blocking rod 508 are simultaneously driven to change, so as to form clamping. And during this process, due to the clamping of the pile, there is a clamping force acting.

[0051] In addition, the fixing columns 503 are fixedly connected to the inside of the fixing box 4. The rotating seat A 506 is rotatably connected to the inner end of the V-shaped control rod 501 through a pin shaft. The rotating seat B 507 is rotatably connected to one of the claws of the three-claw limiting rod 504 through a pin shaft.

[0052] Through the expansion and contraction of the expansion rod 505 of the present invention, the angle of the three-claw limiting rod 504 is driven to change.

[0053] In addition, one end of each of the three-claw limiting rod 504, the first blocking rod 508 and the second blocking rod 509 is provided with a rotating column 5013. An empty groove 5014 is opened in the middle of the anti-tilting positioning column 5011. Two adjusting grooves 5015 are symmetrically opened inside the empty groove 5014. The adjusting grooves 5015 are rotatably connected to the rotating columns 5013.

[0054] Through the present invention, when clamping the pile, due to the action of the clamping force, the anti-tilting positioning column 5011 adapts to the outer wall radian of the pile by changing the angle, so that a certain distance of the pile is stuck inside the arc-shaped anti-tilt grooves 5011, thus ensuring the verticality of the pile.

[0055] On the basis of the above embodiments, a movable pile driving box 1 with liftable adjustment is adopted. After one pile driving is completed, the height of the movable pile driving box 1 is adjusted so that the diameter-adaptive anti-tilting clamping mechanism 5 can clamp and fix the pile again. Subsequently, pile driving by knocking is carried out again, and the same pile can be knocked multiple times.

[0056] To improve the coherence of pile driving, simplify the pile driving mechanism and control strategy, and reduce the redundancy of the device, the adjusting rod 301 adopts the structure as Figure 7 shown. The rotating groove 103 penetrates one side surface of the movable pile driving box 1. One end of the adjusting rod 301 is rotatably connected to one side of the surface of the fixed box 4, and the adjusting rod 301 moves in the rotating groove 103.

[0057] In this technical solution, as Figure 7 and Figure 8 shown, the adjusting rod 301 adopts a bent structure. When the fixed box 4 reciprocates inward and outward along the movable pile driving box 1, it drives the adjusting rod 301 rotatably connected thereto to move accordingly. Since the adjusting rod 301 is rotatably connected to the V-shaped limiting plate 302, the adjusting rod 301 can rotate, thereby driving the V-shaped limiting plate 302 to change its angle. Through the limiting of the balance rod 303, the pile driving column 305 can move up and down for pile driving. By using one driving component, the fixed box 4 can be driven to reciprocate inward and outward, and at the same time, the pile driving column 305 moves downward for pile driving, which can reduce the structural and control redundancy of the device and improve the integration degree of the device structure and control.

[0058] When the anti-tilting pile driving device is needed, first, place the movable pile driving box 1 at the required position. At this time, drive the output shaft of the motor 102 to rotate through the controller. The outer end of the movable rod 308 is coaxially connected to the output shaft of the motor 102, driving the movable rod 308 to rotate, so that the fixed box 4 can reciprocate inward and outward. When the fixed box 4 extends, at this time, place the pile inside the inner side of the arc-shaped groove 401. At this time, drive the telescopic rod 505 to expand and contract through the controller, driving the change of the angle of the three-claw limiting rod 504. And due to the change of the angle of the three-claw limiting rod 504, and the connecting rods 5010 are all rotatably connected to the three-claw limiting rod 504. At this time, the angles of the second stop rod 509 and the first stop rod 508 are changed simultaneously, forming a clamping. And during this process, due to the clamping force acting on the pile when clamping the pile, the anti-tilting positioning column 5011 changes its angle to adapt to the outer wall radian of the pile, so that a certain distance of the pile is stuck inside the arc-shaped anti-tilting groove 5011, thus ensuring the verticality of the pile. Subsequently, drive the motor 102 to drive the fixed box 4 to retract;

[0059] The V-shaped limit plate 302 is driven by the adjusting rod 301 to change the angle. A balance rod 303 is arranged in parallel at the upper end of the V-shaped limit plate 302, so that it can be limited by the balance rod 303. With the arrangement that the balance rod 303 and the V-shaped limit plate 302 are rotatably connected to the holes inside the protective cover 2, the pile driving column 305 can move up and down, avoiding the cumbersome process of drilling holes first and then placing the pile, improving the pile driving efficiency. At the same time, the staff can stay away, avoiding the dangerous situation that is likely to occur when manually placing and then knocking. This enables the pile driving column 305 to accurately knock and fix the pile when knocking.
