Description

Technical Field

[0001] The present invention relates to the technical field of hoisting devices, and in particular to a turning hoisting device and method for steel pipe pile construction. Background Art

[0002] Steel pipe piles are construction engineering supplies composed of steel pipes, tongue and groove mortise and tenon pins. The tongue and groove groove is vertically connected to the left end of the steel pipe diameter. The cross-section of the tongue and groove groove is a square frame with one side open. Reinforcing ribs are provided on the side of the tongue and groove groove. The tongue and groove pin is vertically connected to the right end of the steel pipe diameter and at a radial position. The groove section of the tongue and groove pin is I-shaped. During the specific installation process, the steel pipe pile needs to be hoisted by a crane when it is turned over due to its large size and mass.

[0003] It should be noted that during hoisting, the driver operates in the cab and turns over and hoists the steel pipe piles by controlling the hook on the crane arm. However, the installation environment of the steel pipe piles is very complex and is generally an initial construction site with very simple conditions. At the same time, due to the large size and mass of the steel pipe piles themselves, or due to the operator's mistakes, or the poor support conditions at the construction site, the problem of crane overturning may still occur during the hoisting process. During the overturning process of the crane, the driver is often very nervous under the conditions of the overturning and is easily stuck in the small space of the cab, making it impossible for the driver to escape quickly. Therefore, when a rollover accident occurs, it is easy to damage equipment and materials, but it is also very easy to cause personal injury. Summary of the Invention

[0015] Furthermore, in a preferred embodiment of the present invention, limiting slide bars are installed on both inner walls of the cockpit, and the driving push frame is slidably installed on the two limiting slide bars;

[0016] A pushing shaft is rotatably mounted on the rotating push rod, and the pushing shaft is movably mounted in the driving push frame.

[0021] Furthermore, in a preferred embodiment of the present invention, four transfer push-pull racks are slidably mounted on the bottom side of the integrated rack, and the four transfer push-pull racks are moved to push the four flip plates to rotate;

[0022] Buffer rods are installed at the four corners of the top side of the integrated frame, and four buffer grooves are opened on the bottom side of the crane chassis. The top ends of the four buffer rods are movably installed in the four buffer grooves, and buffer springs are installed on each of them. The top ends of the buffer springs are installed on the inner wall of the top side of the buffer groove.

[0023] Furthermore, in a preferred embodiment of the present invention, a rotating frame is rotatably mounted on the bottom side of the crane chassis, a cross is mounted on the rotating frame, and synchronous sliding shafts are rotatably mounted at the four corners of the cross, and the four synchronous sliding shafts are movably mounted in the four transfer push-pull frames respectively;

[0024] A jacking groove is provided at the center position of each of the four sides of the cross, and a jacking rod is movably installed in each of the four jacking grooves. Four locking grooves are provided on the bottom side of the crane chassis, and the four jacking rods are respectively stuck in the four locking grooves. A jacking spring is installed on the bottom side of the jacking rod, and the bottom end of the jacking spring is installed on the bottom inner wall of the jacking groove.

[0025] A method for turning over and hoisting steel pipe piles for construction is carried out according to the above-mentioned turning over and hoisting device for steel pipe pile construction, comprising the following steps:

[0026] S1. Push the rotating frame with force to drive the cross to rotate. The cross drives the four transfer push-pull frames to move through the four synchronous sliding shafts. The movement of the transfer push-pull frames drives the flip plate to rotate. The rotation of the cross drives the four jacking rods to move, and they are squeezed by the bottom side of the crane chassis, so that the jacking rods retract into the jacking slots and drive the jacking springs to be stressed. When the cross rotates ninety degrees, the four jacking rods correspond to the positions of the four locking slots respectively. Under the rebound force of the four jacking springs, the four jacking rods are respectively stuck in the four locking slots, so that the position of the cross is fixed and the flip plate is fixed in a state perpendicular to the integrated frame, so that the moving wheels are in contact with the ground.

[0027] S2. The crane chassis shakes slightly, squeezing the two moving wheels on either side to move, which in turn drives the integrated frame to move through the flip plate. The integrated frame moves in the four buffer slots through the four buffer rods, and drives the buffer springs to bear force. At this time, the flip plate is cushioned by the rebound force of the buffer springs.

[0028] S3. The tilt angle of the crane chassis is large, so that the integrated frame directly pushes the upper push frame to move, and the upper push frame drives the lifting column to move. The lifting column drives the arc block to rotate by pushing the friction, and then drives the rotating push rod to rotate. The rotating push rod synchronously drives the driving sleeve to rotate. At the same time, the rotating push rod drives the driving push frame to move through the ejection shaft. The driving push frame drives the seat out of the cockpit through the sliding push plate. At the same time, the driving push frame slides horizontally on the two limiting slide bars, so that the driver is separated from the cockpit.

[0029] S4. When the driving push frame drives the seat out of the cockpit through the sliding push plate, the blocking block is simultaneously driven to disengage from the cockpit. Under the return force of the recovery spring, the blocking block is pulled back to its original position and no longer blocks the seat. Under the torsional force of the rotating torsion spring, the seat rotates on the support shaft and is rotated to a state perpendicular to the cockpit.

[0030] The beneficial effects of the turning and hoisting device and method for steel pipe pile construction proposed by the present invention are:

[0031] In the present invention, through the setting of the emergency ejection device, when lifting steel pipe piles for turning operations, if the tilt angle of the crane chassis is large, the integrated frame directly pushes the upper push frame to move, the upper push frame drives the lifting column to move, the lifting column drives the arc block to rotate through the pushing groove, and then drives the rotating push rod to rotate, the rotating push rod drives the driving push frame to move, and the driving push frame drives the seat out of the cockpit through the sliding push plate, so that the driver can leave the cockpit in time, which is convenient for the driver to escape.

[0032] Furthermore, in the present invention, through the setting of the automatic rotation device, when the driving push frame drives the seat out of the cockpit through the sliding push plate, the blocking block is synchronously driven to disengage from the cockpit. At this time, the blocking block is pulled back to its original position under the return force of the recovery spring and no longer blocks the seat. At the same time, under the torsional force of the rotating torsion spring, the seat is rotated on the support shaft, and then the seat is rotated to a state perpendicular to the cockpit, further facilitating the driver's escape.

[0033] Furthermore, in the present invention, through the setting of the buffer trigger device, when the lifting arm lifts the steel pipe pile for turning over and a slight shake occurs, the two moving wheels on either side are squeezed to move, and then the integrated frame is driven to move through the flip plate. The integrated frame moves in the four buffer grooves through four buffer rods, and drives the buffer spring to be stressed. At this time, under the rebound force of the buffer spring, a buffer force is provided for the flip plate. If the crane chassis tilts too much, the emergency ejection device can be automatically triggered to push the seat out. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] For further information, please refer to the attached manual. Figure 3 -Attached Figure 5 , an embodiment of the present invention provides a turning and hoisting device for steel pipe pile construction, wherein an emergency pushing device 4 is installed on the cockpit 2, and the emergency pushing device 4 is used to urgently push out the seat 3; specifically, the emergency pushing device 4 includes a sliding push plate 401, which is slidably installed in the cockpit 2, and the seat 3 is movably installed on the sliding push plate 401. A driving push frame 402 is installed on one side of the sliding push plate 401, and a rotating push rod 405 is rotatably installed on the inner wall of the bottom side of the cockpit 2. The driving push frame 402 is movably installed on the rotating push rod 405. The rotating push rod 405 rotates and pushes the sliding push plate 401 to slide through the driving push frame 402, so as to push the seat 3 out of the cockpit 2. It should be noted that in the embodiment of the present invention, if the tilt angle of the crane chassis 1 is large, the integrated frame 601 drives the lifting column 404 to move, the lifting column 404 drives the rotating push rod 405 to rotate, the rotating push rod 405 drives the driving push frame 402 to move through the pushing shaft 406, and the driving push frame 402 drives the seat 3 out of the cockpit 2 through the sliding push plate 401, so that the driver can detach from the cockpit 2 in time, facilitating the driver's escape.

[0054] More specifically, in the embodiment of the present invention, the emergency ejection device 4 is equipped with an automatic rotation device 5, and the seat 3 is rotationally mounted on the automatic rotation device 5. The automatic rotation device 5 is used to rotate the seat 3. The automatic rotation device 5 includes a support shaft 501, which is mounted on the sliding push plate 401. The bottom side of the seat 3 is provided with a rotation groove 502, and the support shaft 501 is rotatably mounted in the rotation groove 502. A rotation torsion spring 503 is mounted on the inner wall of the rotation groove 502, and the other end of the rotation torsion spring 503 is mounted on the support shaft 501. It should be noted that in the embodiment of the present invention, when the seat 3 is ejected from the cockpit 2, the blocking block 504 is simultaneously disengaged from the cockpit 2. At this time, the return force of the recovery spring 506 pulls the blocking block 504 back to its original position and no longer blocks the seat 3. At this time, the torsional force of the rotation torsion spring 503 causes the seat 3 to rotate on the support shaft 501, thereby rotating the seat 3 to a position perpendicular to the cockpit 2, further facilitating the driver's escape.

[0055] More specifically, in an embodiment of the present invention, a buffer trigger device 6 is further included. The buffer trigger device 6 is installed on the bottom side of the crane chassis 1. The buffer trigger device 6 is used to buffer the bottom side of the crane chassis 1 and trigger the emergency ejection device 4; the buffer trigger device 6 includes an integrated frame 601, and the integrated frame 601 is movably installed on the bottom side of the crane chassis 1. The center positions of the four sides of the integrated frame 601 are rotatably installed with flip plates 603, and both sides of the flip plate 603 are rotatably installed with moving wheels 604. When the crane chassis 1 is tilted, the integrated frame 601 is squeezed and moved by the moving wheels 604. It should be noted that, in the embodiment of the present invention, when the lifting arm 7 lifts the steel pipe pile for turning over and slight shaking occurs, the two moving wheels 604 on either side are squeezed to move, and then the integrated frame 601 is driven to move through the flip plate 603. The integrated frame 601 moves in the four buffer grooves 615 through the four buffer rods 616, and drives the buffer spring 617 to be subjected to force. At this time, under the rebound force of the buffer spring 617, a buffer force is provided for the flip plate 603.

[0056] Please continue to refer to the instructions attached Figure 3-5 Furthermore, in an embodiment of the present invention, a turning and hoisting device for steel pipe pile construction is provided, wherein the emergency ejection device 4 further includes a lifting column 404, and the lifting column 404 is movably mounted on the bottom side of the crane chassis 1;

[0057] In addition, a drive sleeve 407 is mounted on the top side of the rotating push rod 405. The drive sleeve 407 is integrally provided with the rotating push rod 405, and the lifting column 404 is movably mounted within the rotating push rod 405 and the drive sleeve 407. It should be noted that in the embodiment of the present invention, when the lifting column 404 rotates, it rotates within the rotating push rod 405 and the drive sleeve 407, thereby achieving the purpose of pushing out the seat 3.

[0058] More specifically, in this embodiment of the present invention, an upper push frame 408 is mounted on the bottom side of the lifting column 404. The integrated frame 601 moves upward to push the upper push frame 408. Furthermore, a return spring 409 is mounted on the top side of the upper push frame 408, with the top end of the return spring 409 mounted on the bottom side of the crane chassis 1. It should be noted that in this embodiment of the present invention, when the integrated frame 601 pushes the upper push frame 408 to move, it simultaneously applies force to the return spring 409. Consequently, the return force of the return spring 409 helps the upper push frame 408 to reset the lifting column 404.

[0059] Please continue to refer to the instructions attached Figure 3 -Attached Figure 5More specifically, in this embodiment of the present invention, a push slot 410 is formed in an arc shape on the lifting column 404, and a push arc block 411 is mounted on the inner wall of the rotating push rod 405. The lifting column 404 moves vertically, pushing the push arc block 411 through the push slot 410, thereby driving the rotating push rod 405 to rotate. It should be noted that in this embodiment of the present invention, when the integrated frame 601 pushes the upper push frame 408 to move, it drives the lifting column 404 to move vertically. The lifting column 404 rotates within the rotating push rod 405 and the drive sleeve 407, and then drives the push arc block 411 to rotate through the push slot 410, causing the rotating push rod 405 to rotate.

[0060] More specifically, in the embodiment of the present invention, limiting slide bars 403 are installed on both sides of the inner wall of the cockpit 2, and the driving push frame 402 is slidably mounted on the two limiting slide bars 403; a push shaft 406 is rotatably mounted on the rotating push rod 405, and the push shaft 406 is movably mounted within the driving push frame 402. It should be noted that in the embodiment of the present invention, when the rotating push rod 405 rotates, the driving sleeve 407 is synchronously rotated, and the rotating push rod 405 drives the driving push frame 402 to move via the push shaft 406. The push shaft 406 slides within the driving push frame 402, thereby causing the sliding push plate 401 to drive the seat 3 out of the cockpit 2. At the same time, the driving push frame 402 slides horizontally on the two limiting slide bars 403, allowing the driver to promptly detach from the cockpit 2.

[0061] Please refer to the attached manual Figure 3 and Figure 6 , further specifically, in the embodiment of the present invention, the automatic rotation device 5 further includes a blocking block 504, the bottom side of the blocking block 504 is arranged in an arc shape, the blocking block 504 is slidably mounted on one side of the sliding push plate 401, and the blocking block 504 is used to block the rotation of the seat 3;

[0062] In addition, a retraction groove 505 is formed on one side of the sliding push plate 401, and a blocking block 504 is slidably mounted in the retraction groove 505. A recovery spring 506 is mounted on the bottom side of the blocking block 504, and the bottom end of the recovery spring 506 is mounted on the bottom inner wall of the retraction groove 505. It should be noted that in this embodiment of the present invention, when the seat 3 is driven out of the cockpit 2, the blocking block 504 is simultaneously driven to disengage from the cockpit 2. At this time, the return force of the recovery spring 506 pulls the blocking block 504 back to its original position and no longer blocks the seat 3. At the same time, the torsional force of the rotating torsion spring 503 causes the seat 3 to rotate on the support shaft 501, thereby rotating the seat 3 to a position perpendicular to the cockpit 2, thereby facilitating the driver's escape.

The ends of the connecting shaft 613 are mounted on the inner walls of the mounting base 602. A rebound torsion spring 614 is mounted on the inner wall of the rebound groove 612, with the other end of the rebound torsion spring 614 mounted on the connecting shaft 613. It should be noted that in this embodiment of the present invention, when the flip plate 603 rotates, it rotates on the connecting shaft 613 via the rebound groove 612, thereby applying force to the rebound torsion spring 614.

Four locking slots 618 are provided on the bottom side of the crane chassis 1, and the four jacking rods 609 are respectively locked in the four locking slots 618. A jacking spring 610 is installed on the bottom side of the jacking rod 609, and the bottom end of the jacking spring 610 is installed on the bottom inner wall of the jacking slot 608. It should be noted that in the embodiment of the present invention, when the lifting arm 7 lifts the steel pipe pile to perform the turning operation, the rotating frame 611 is first rotated to drive the cross 606 to rotate. The cross 606 drives the four transfer push-pull frames 605 to move through the four synchronous sliding shafts 607. At the same time, the synchronous sliding shafts 607 slide in the transfer push-pull frames 605. The transfer push-pull frames 605 move and push the flip plate 603 to rotate. The rotation of the cross 606 simultaneously drives the four jacking rods 609 to move and is driven by the crane chassis 1 The bottom side is squeezed, causing the lifting rod 609 to retract into the lifting groove 608, and driving the lifting spring 610 to be stressed; when the cross 606 rotates ninety degrees, the four lifting rods 609 correspond to the positions of the four locking grooves 618 respectively. At this time, under the rebound force of the four lifting springs 610, the four lifting rods 609 are helped to be stuck into the four locking grooves 618 respectively, so that the position of the cross 606 can be fixed, thereby achieving the purpose of vertically fixing the flip plate 603.

[0068] In summary, the working principle of a turning and hoisting device for steel pipe pile construction provided by an embodiment of the present invention, that is, the method of using the turning and hoisting device for steel pipe pile construction is as follows:

[0069] When the lifting arm 7 lifts the steel pipe pile for turning over, the rotating frame 611 is first rotated to drive the cross 606 to rotate. The cross 606 drives the four transfer push-pull frames 605 to move through the four synchronous sliding shafts 607. The transfer push-pull frames 605 move and drive the flip plate 603 to rotate. The flip plate 603 rotates on the connecting shaft 613 through the rebound groove 612 and drives the rebound torsion spring 614 to be stressed. The rotation of the cross 606 drives the four lifting clamping rods 609 to move at the same time, and is squeezed by the bottom side of the crane chassis 1, so that the lifting The card rod 609 retracts into the lifting groove 608, and drives the lifting spring 610 to be stressed; when the cross 606 rotates 90 degrees, the four lifting card rods 609 correspond to the positions of the four locking card grooves 618 respectively. At this time, under the rebound force of the four lifting springs 610, the four lifting card rods 609 are helped to be respectively locked into the four locking card grooves 618, so that the position of the cross 606 can be fixed, and at the same time, the flip plate 603 is fixed in a state perpendicular to the integrated frame 601, so that the moving wheel 604 is in contact with the ground;

[0070] Furthermore, when the hoist is being hoisted and a slight shake occurs, the two moving wheels 604 on either side are squeezed to move, thereby driving the integrated frame 601 to move through the flip plate 603. The integrated frame 601 moves in the four buffer grooves 615 through the four buffer rods 616, and drives the buffer springs 617 to be stressed. At this time, the rebound force of the buffer springs 617 provides a buffer force for the flip plate 603.

[0071] It should be noted that if the tilt angle of the crane chassis 1 is large, the integrated frame 601 directly pushes the upper push frame 408 to move, and the upper push frame 408 drives the lifting column 404 to move. The lifting column 404 drives the arc block 411 to rotate through the pushing groove 410, thereby driving the rotating push rod 405 to rotate. The rotating push rod 405 synchronously drives the driving sleeve 407 to rotate. At the same time, the rotating push rod 405 drives the driving push frame 402 to move through the pushing shaft 406. The driving push frame 402 drives the seat 3 out of the cockpit 2 through the sliding push plate 401. At the same time, the driving push frame 402 slides horizontally on the two limiting slide bars 403, so that the driver can leave the cockpit 2 in time, which is convenient for the driver to escape.

[0072] Furthermore, when the driving push frame 402 drives the seat 3 out of the cockpit 2 through the sliding push plate 401, the blocking block 504 is simultaneously driven to disengage from the cockpit 2. At this time, the blocking block 504 is pulled back to its original position under the return force of the recovery spring 506 and no longer blocks the seat 3. At this time, under the torsional force of the rotating torsion spring 503, the seat 3 rotates on the support shaft 501, and then the seat 3 rotates to a state perpendicular to the cockpit 2, further facilitating the driver's escape.

[0073] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.

Push the rotating frame with force to drive the cross to rotate. The cross drives the four transfer push-pull frames to move through the four synchronous sliding shafts. The movement of the transfer push-pull frames drives the flip plate to rotate. The rotation of the cross drives the four jacking rods to move, and they are squeezed by the bottom side of the crane chassis, so that the jacking rods retract into the jacking slots and drive the jacking springs to be stressed. When the cross rotates ninety degrees, the four jacking rods correspond to the positions of the four locking slots respectively.
