Description

Technical Field

[0001] This invention relates to a steel structure factory building hoisting equipment and hoisting method, belonging to the technical field of steel structure hoisting equipment. Background Technology

[0002] When constructing a steel structure factory building, various prefabricated steel components need to be hoisted and assembled. Hoisting typically involves two truck cranes working together, requiring several experienced personnel for coordination and command. This results in a large workforce and high labor costs. Furthermore, during hoisting, steel components often exhibit axial torsion and tilting after being horizontally lifted by two truck cranes. Vertical hoisting, using only one truck crane, also results in tilting and axial torsion. These issues require manual adjustments by construction personnel and cannot be resolved by the truck cranes themselves. High-altitude operations are risky, time-consuming, and labor-intensive. Moreover, when using a truck crane for traction hoisting, precise positioning is difficult due to the swaying of the steel components at high altitudes, requiring repeated fine-tuning. To address these problems, this invention proposes a steel structure factory building hoisting equipment and method. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a steel structure factory building hoisting equipment and hoisting method to solve the existing problems.

[0009] A further improvement is that the inner panel assembly includes a fixed base, on which an L-shaped inner panel is hinged. The lower end of the L-shaped inner panel has a horizontal groove for a clamping mechanism. A support pad is provided at the bottom left side of the groove. A second hydraulic telescopic cylinder for lifting the left end of the L-shaped inner panel is installed on the bottom surface of the left end of the L-shaped inner panel. Multiple auxiliary support components are spaced apart on the outer side of the L-shaped inner panel for correspondingly fitting into the buffer rod sleeve holes. An angle sensor is also provided on the side of the L-shaped inner panel. Each auxiliary support component includes a universal joint, on which a support rod is hinged, and on the support rod are fitted a sliding sleeve and a first compression spring; The second hydraulic telescopic cylinder drives the left end of the L-shaped inner plate to rise to a maximum angle of 45º.

[0010] A further improvement is that the clamping mechanism includes two transverse sliding rods, with a clamping plate assembly and a guide rope slide seat spaced apart between the two transverse sliding rods. A second compression spring and a third compression spring are also spaced apart on the rods of the two transverse sliding rods. A third winding device is installed between the clamping plate assembly and the guide rope slide seat to pull the clamping plate assembly to the right and simultaneously swing the head to the upper right.

[0011] A further improvement is that the clamping plate assembly includes a first pull base, on which a lifting pressure plate is hinged. A return spring is fitted at the hinge point between the first pull base and the lifting pressure plate to cause the lifting pressure plate to flip down to the left.

Two first guide rope wheels and rope rings are fixed at the left and right openings of the pull rope guide channel, respectively. A pressure pad is provided on the top surface of the lifting pressure plate, and multiple pressure sensors are built into the pressure pad.

[0012] A further improvement is that the guide rope slide includes a second pull seat, and a second guide rope wheel and a third guide rope wheel are arranged horizontally on the top surface of the second pull seat.

[0013] A further improvement is that the main body of the hoisting vehicle has a built-in cross slide body, and the top surface of the cross slide body is equipped with a rotating bearing for axial rotation of the lifting boom. All of these are existing technologies, and the structure will not be described in detail here.

[0014] Further improvements are made to the fact that the lifting boom, lifting arm, lifting cross arm, first winder, hook, first camera body, second camera, electromagnetic chuck body, second winder, rotary encoder body, second hydraulic telescopic cylinder, tilt sensor, third winder and pressure sensor are all existing technologies, and their structures will not be described in detail here.

[0016] Furthermore, this invention also provides a hoisting method for the aforementioned steel structure workshop hoisting equipment, the hoisting method being as follows: First, move the steel component below the hook, and then use the first retractor to lower the hook and vertically lift the steel component, allowing it to rise to the front of the assembly auxiliary end.

[0017] Then, the first camera scans the steel component. When there is still a slight height difference between the steel component and the inner panel assembly, the lifting seat assembly drives the inner panel assembly to adjust its vertical height. Then, the rotating horizontal push seat drives the inner panel assembly to swing so that the tilt angle of the inner panel assembly and the steel component after being lifted is consistent. Then, the first hydraulic telescopic cylinder drives the inner panel assembly to move laterally towards the steel component, so that the steel component fits into the cavity of the L-shaped inner panel and abuts against the electromagnetic suction plate body. Then, the first winding device lowers the steel component onto the top surface of the inner cavity of the L-shaped inner panel.

[0018] Then, the right side of the steel component is magnetically fixed by the electromagnetic suction plate. Then, the left side of the steel component is pressed and tightened by the rightward lateral movement and upward lifting of the clamping mechanism. After the steel component is hoisted, it is placed on the assembly auxiliary end.

[0019] Then, the lifting boom lifts the steel components on the assembly auxiliary end to the corresponding installation height. At this time, the installation position is found by scanning with two second cameras. The lifting boom does not make precise height adjustments. When there are slight deviations in the height, left and right position, tilt angle, front and back swing of the steel components from the assembly position, the corresponding functions of the assembly auxiliary end are used for fine-tuning and correction to ensure that the steel components can be accurately aligned and spliced.

[0020] After the steel components are finally assembled, the lifting ropes on the hooks are removed, and then the various mechanisms on the assembly auxiliary end are reset in sequence to release the clamps on the steel components.

[0021] The beneficial effects of this invention are: This invention provides a steel structure factory hoisting equipment and method. The equipment comprises an assembly auxiliary end consisting of an upright boom, a lifting seat assembly, a first hydraulic telescopic cylinder, a support slide bar, a rotating horizontal push seat, a directional auxiliary assembly mechanism, and a clamping mechanism, integrated between the lifting boom and the lifting arm.

Through the coordination of multiple adjustment functions, it is convenient to assist in the horizontal adjustment of large-volume steel components hoisted by the first winding device and hook on the lifting arm. This allows the assembly auxiliary end to correct tilting and axial torsion issues of large-volume steel components in a suspended state, facilitating precise alignment and installation without the need for manual adjustment by construction personnel, saving time and effort, and reducing the risks of high-altitude operations.

[0029] The inner panel assembly 362 includes a fixed base 3621, on which an L-shaped inner panel 3622 is hinged. A horizontal groove 3623 for a clamping mechanism is laterally formed at the lower end of the L-shaped inner panel 3622. A support pad 3624 is provided at the bottom left side of the groove 3623.

[0030] The clamping mechanism 37 includes two transverse sliding rods 371. A clamping plate assembly 372 and a guide rope slide 373 are spaced apart between the two transverse sliding rods 371.

A third winding device 376 is installed between the clamping plate assembly 372 and the guide rope slide 373 to pull the clamping plate assembly to the right and simultaneously swing the head to the upper right.

[0031] The clamping plate assembly 372 includes a first pull base 3721, on which a lifting pressure plate 3722 is hinged. A return spring 3723 is fitted at the hinge point between the first pull base 3721 and the lifting pressure plate 3722 to make the lifting pressure plate 3722 automatically flip to the left and down. A pull rope guide channel 3724 is provided through the middle of the lifting pressure plate 3722. Two first guide rope wheels 3725 and rope rings 3726 are fixed at the left and right openings of the pull rope guide channel 3724, respectively. A pressure pad 3727 is provided on the top surface of the lifting pressure plate 3722. Multiple pressure sensors 3728 are built into the pressure pad 3727.

[0032] The guide rope slide 373 includes a second pull seat 3731, and a second guide rope wheel 3732 and a third guide rope wheel 3733 are arranged horizontally on the top surface of the second pull seat 3731.

[0033] Working principle: First, move the steel component below the hook 7, and then use the first retractor 6 to lower the hook 7 and vertically lift the steel component, allowing the steel component to rise to the front of the assembly auxiliary end 3.

[0034] The hoisting of the first coiler 6 and the hook 7 is a conventional technique, so I won't go into details. In addition, for small-volume steel components, the first coiler 6 and the hook 7 are used for direct hoisting without the assistance of the assembly auxiliary end 3. The assembly auxiliary end 3 is only used for the auxiliary installation of large-volume steel components.

[0035] Then, the first camera body 363 scans the steel component. When there is still a slight height difference between the steel component and the inner panel assembly 362, the lifting seat assembly 32 drives the inner panel assembly 362 to adjust vertically. Then, the rotating horizontal push seat 35 drives the inner panel assembly 362 to swing so that the tilt angle of the inner panel assembly 362 is consistent with that of the steel component after it is lifted. Then, the first hydraulic telescopic cylinder 33 drives the inner panel assembly 362 to move laterally towards the steel component, so that the steel component is inserted into the cavity of the L-shaped inner panel 3622 and abuts against the electromagnetic suction plate body 365. Then, the first winding device 6 lowers the steel component onto the top surface of the inner cavity of the L-shaped inner panel 3622.

[0036] In addition, the lifting seat assembly 32 is raised and lowered by the second retractor 323 pulling the lifting seat assembly 32 to slide up and down on the slide rail 312.

[0037] In addition, the rotating horizontal pusher 35 drives the inner plate assembly 362 to swing, and the servo motor 355 drives the ring gear 354 to rotate, so that the rotating seat 353 rotates on the load-bearing turntable 352. The rotary encoder body 3614 will sense the rotation angle of the L-shaped outer plate 361.

[0038] See also the attached document. Figure 1When the lifting boom 5 tilts to the left, the corresponding inner panel assembly 362 will also tilt to the left. At this time, the second hydraulic telescopic cylinder 3625 is needed to lift the left end of the L-shaped inner panel 3622 upwards so that the L-shaped inner panel 3622 is in a horizontal state. The auxiliary support 3626 acts as a stable support during the lifting. During the lifting process of the inner panel assembly 362, the tilt sensor 3627 will sense the tilt angle of the inner panel assembly 362.

[0039] Then, the right side of the steel component is magnetically fixed by the electromagnetic suction plate body 365. Then, the left side of the steel component is pressed and tightened by the rightward lateral movement and upward lifting of the clamping mechanism 37. After the steel component is hoisted, it is placed on the assembly auxiliary end 3.

[0040] In addition, when the clamping mechanism 37 is pulled to the right by the third winding device 376, the force to the right will cause the lifting pressure plate 3722 to flip to the right and upward on the first pull seat 3721. After the lifting pressure plate 3722 flips to the right and upward to a certain angle, the two first guide rope wheels 3725, the second guide rope wheel 3732 and the third guide rope wheel 3733 can make the steel rope on the third winding device 376 pull in an L-shape to prevent the steel rope from hitting the left side of the steel component and getting stuck.

[0041] In addition, when the pressure pad 3727 presses against the left side of the steel component, the pressure sensor 3728 will sense the pressure intensity, so that the third winding device 376 can determine whether it has been pulled into place.

[0042] Then, the lifting boom 2 drives the steel components on the assembly auxiliary end 3 to rise to the corresponding installation height. At this time, the installation position is found by scanning with two second cameras 364. The lifting boom 2 does not make precise height adjustment. When there is a slight deviation between the height, left and right position, tilt angle, front and back swing of the steel components and the assembly position, the corresponding function of the assembly auxiliary end 3 is used to make fine adjustment and correction so that the steel components can be accurately aligned and spliced.

[0043] Additionally, please refer to the appendix. Figure 1 The first hydraulic telescopic cylinder 33 on the assembly auxiliary end 3 can drive the rotating horizontal push seat 35 to make horizontal left and right lateral displacement, while the front and rear longitudinal displacement of the rotating horizontal push seat 35 requires the auxiliary operation of the cross slide body built into the main body of the crane vehicle 1.

[0044] After the steel components are finally assembled, the lifting rope on the hook 7 is removed, and then the various mechanisms on the assembly auxiliary end 3 are reset in sequence to release the clamps on the steel components.
