Description

Technical Field

[0001] The 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 is vertically connected to the pipe wall at the left end of the steel pipe diameter. The cross-section of the tongue and groove is a square frame with one side open. Reinforcing ribs are provided on the side of the tongue and groove. A tongue and groove pin is vertically connected to the pipe wall at 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 of the steel pipe pile, due to its large size and mass, it is necessary to use a crane to lift the steel pipe pile when turning it over.

[0003] It should be noted that during hoisting, the driver operates in the cab and controls the hook on the crane arm to turn over and hoist the steel pipe piles. 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 mistakes of the operators, or the poor support conditions of the construction site, the crane may still overturn 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, in the event of a rollover accident, it is not only easy to damage equipment and materials, but also very easy to cause personal injury. Summary of the invention

[0014] A method for turning over and hoisting steel pipe pile construction is carried out according to the above-mentioned turning over and hoisting device for steel pipe pile construction, and comprises the following steps: 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 four synchronous sliding shafts. The transfer push-pull frames move and drive the flip plate to rotate. The rotation of the cross drives the four jacking rods to move and 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 90 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; S2. The crane chassis shakes slightly, squeezing the two moving wheels on either side to move, and then driving the integrated frame 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, the flip plate is buffered under the rebound force of the buffer spring; S3. The tilt angle of the crane chassis is relatively 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 drives the driving sleeve to rotate synchronously. At the same time, the rotating push rod drives the driving push frame to move through the push shaft. The driving push frame drives the seat out of the cockpit through the sliding push plate, and 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; 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 is rotated on the support shaft to a state perpendicular to the cockpit.

[0015] The beneficial effects of the turning over and hoisting device and method for steel pipe pile construction proposed by the present invention are: In the present invention, by setting up the emergency ejection device, when lifting the steel pipe pile for turning over operation, if the tilt angle of the crane chassis is large, at this time 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.

[0016] 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 by sliding the push plate, the blocking block is synchronously driven to disengage from the cockpit. At this time, the blocking block is pulled to reset 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 rotates on the support shaft, and then the seat rotates to a state perpendicular to the cockpit, further facilitating the driver's escape.

[0017] 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 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

At the same time, the synchronous sliding shafts 607 slide in the transfer push-pull frames 605. The transfer push-pull frames 605 move to push the flip plate 603 to rotate. The rotation of the cross 606 simultaneously drives the four lifting rods 609 to move and is driven by the crane chassis 1 The bottom side is squeezed, so that the lifting rod 609 retracts into the lifting groove 608, and drives 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.

[0038] 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: When the lifting arm 7 lifts the steel pipe pile for turning over, first the rotating frame 611 is rotated to drive the cross 606 to rotate, and the cross 606 drives the four transfer push-pull frames 605 to move through the four synchronous sliding shafts 607, and the transfer push-pull frames 605 move to drive the flip plate 603 to rotate, and 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, and the rotation of the cross 606 drives the four jacking clamping rods 609 to move at the same time, and is squeezed by the bottom side of the crane chassis 1, so that the jacking The clamping rod 609 retracts into the lifting groove 608 and drives the lifting spring 610 to bear force; when the cross 606 rotates 90 degrees, the four lifting clamping rods 609 correspond to the positions of the four locking clamping grooves 618 respectively. At this time, under the rebound force of the four lifting springs 610, the four lifting clamping rods 609 are helped to be respectively locked into the four locking clamping 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; Furthermore, when the hoisting is performed and a slight shake 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 stressed. At this time, the buffer spring 617 provides a buffer force for the flip plate 603 under the rebound force. 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, 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, and then drives the rotating push rod 405 to rotate, the rotating push rod 405 synchronously drives the driving sleeve 407 to rotate, and at the same time, 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, and 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; Furthermore, when the driving push frame 402 drives the seat 3 out of the cockpit 2 by means of 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 is rotated on the support shaft 501, and then the seat 3 is rotated to a state perpendicular to the cockpit 2, further facilitating the driver's escape.
