Description

Technical Field

[0001] The invention relates to the technical field of construction engineering equipment, in particular to an automatic lifting device for a steel cage. Background Art

[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories (such as floor slabs, wall panels, etc.) are processed and manufactured in the factory, transported to the construction site, and assembled and installed on site through reliable connection methods.

[0003] Prefabricated buildings mainly include prefabricated concrete structures, steel structures, modern wooden structures, etc. Because they adopt standardized design, factory production, assembly construction, information management, and intelligent applications, they are representatives of modern industrialized production methods. They can also effectively improve project quality and are increasingly widely used in modern production.

[0004] In the prior art, prefabricated assembled concrete structures are mainly formed by pouring concrete into a steel cage to shape it. The steel cage is the most basic and important component. During its production process, the top and bottom of the steel cage need to be tied or welded with a full-covered steel mesh. Its function is to effectively prevent the expansion of the mold when grouting the steel cage. When installing the steel mesh at the bottom, the steel cage needs to be lifted to a certain height. The height of the steel cage has a certain range of variation, and the steel cage itself has a large weight, which makes manual handling more cumbersome and laborious. Different projects also have different requirements for the height of the lifting strain. There are also certain requirements for the stability of the device during the lifting process. Existing equipment is difficult to accommodate the requirements of height change and lifting stability. In addition, the ends of the steel cage may not be consistent during the actual production process, and irregular edges may be generated, resulting in some positions falling off the lifting equipment during the lifting of the steel cage, making it impossible for the entire steel cage to be completely lifted smoothly for the installation of the steel mesh at the bottom.

[0005] Therefore, it is urgent to develop an automatic lifting device for steel cages to solve the technical problems in the existing technology that the steel cage lifting device cannot be adjusted to adapt to the different heights of the steel cage and the stability of the lifting process, and the end of the steel cage cannot be placed smoothly on the lifting device as a whole.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) The present invention receives the steel cage transmitted from the previous workstation through a conveyor belt, adjusts the crossbeam frame on the side of the sliding connection with the installation frame, so that the claw mechanism at the lower end of the crossbeam frame on the sliding connection side is slightly close to the end of the steel cage; the lifting cylinder extends to drive the claw mechanism to descend, and the lower end of the claw mechanism descends to the middle position of the steel cage, and the crossbeam frame slidably connected to the installation frame continues to move inward, completely containing the steel cage in the two opposite claw mechanisms, and the lifting cylinder is retracted in an orderly manner; the weld claws are all hooked to the end of the steel cage, and the steel cage is smoothly lifted up, and then the mesh conveying mechanism is placed in the steel mesh at the bottom, and the lifting cylinder is extended again to drive the lifted steel cage to descend and reset.

[0018] (2) The present invention sets a hook mechanism. When encountering a steel cage with an irregular end, the edge of the irregular steel cage contacts the rolling bar first. The rolling bar squeezes the weld claw inward, and the weld claw swings upward to a vertical state, so that the weld claw here is not subjected to force and does not interfere with the normal operation of other weld claws. Multiple groups of weld claws can effectively hook the steel cage as a whole, and will not collapse when the steel cage needs to be transported and lifted, thereby affecting construction efficiency.

[0020] (4) The present invention sets up a diagonal support fixing mechanism. When the lifting cylinder is extended or retracted, the diagonal support mechanism moves along the direction of the guide rail, safely and effectively lifting the steel cage required by the hook mechanism, and the yaw correction mechanism eliminates the eccentric load torque of the slider during movement. The structure is simple, and it can effectively enhance the stability of the lifting device in the automation equipment and extend the service life of each component.

[0040] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0042] In the description of the present invention, unless otherwise specified, "plurality" means two or more; terms such as "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," and "tail" indicate positions or relationships based on those shown in the accompanying drawings. These terms are intended solely to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limiting the present invention. Furthermore, terms such as "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0043] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0044] like Figures 1 to 19 As shown, a mounting frame 1 is fixed on the ground, a crossbeam frame 2 is fixed on one side of the upper end of the mounting frame 1, and a crossbeam frame 2 is slidably provided on the other side of the upper end of the mounting frame 1, a locking mechanism 5 is fixed on the bottom of the crossbeam frame 2, and a diagonal bracing fixing mechanism 3 is fixed on the crossbeam frame 2. The locking mechanism 5 can effectively prevent the sudden fall of the diagonal bracing fixing mechanism 3, and a hook mechanism 4 is fixed at the lower end of the diagonal bracing fixing mechanism 3. A conveyor belt 6 is fixed on the bottom inner side of the mounting frame 1, and the conveyor belt 6 is arranged parallel to the crossbeam frame 2. The conveyor belt 6 is used to receive the workpiece to be processed transmitted from the previous workstation and to transport the processed workpiece to be processed.

[0045] The hook mechanism 4 includes a lifting frame 401, a clamping claw base plate 402, a rebound connector 403, a mounting plate 404 and a clamping claw assembly. The lower end of the lifting frame 401 is fixedly mounted with a clamping claw base plate 402, and the lower end of the clamping claw base plate 402 is fixedly provided with a rebound connector 403; one side of the clamping claw base plate 402 is fixedly connected to the mounting plate 404 by bolts, and a clamping claw assembly is provided on the inner side of the mounting plate 404. The clamping claw assembly includes a clamping plate 405, a limit pin 406, a weldment hand claw 407, a scroll bar 408 and a rotating shaft 409. Multiple groups of clamping plates 405 are fixedly installed in the mounting plate 404, and limit pins 406 are fixedly pierced on the clamping plates 405; welding claws 407 are respectively installed on both sides of the clamping plates 405, and a rolling bar 408 is provided on the upper end of the welding claw 407. The upper end surface of the welding claw 407 is lower than the upper end surface of the rolling bar 408, so that the edge of the steel cage 7 can be smoothly pushed to the welding claw 407 by the rolling bar 408. There is a gap between the two ends of the rolling bar 408 and the clamping plate 405, so that a single welding claw 407 can work independently.

[0046] A relatively rotatable rotating shaft 409 is provided at the lower part of the welding gripper 407, and both ends of the rotating shaft 409 are respectively fixed on the clamping plate 405; waist holes 410 are relatively opened on both sides of the welding gripper 407, and a limit pin 406 is movably sleeved in the waist hole 410.

[0047] The lower end of the welding claw 407 is arc-shaped, and a gap is left between the welding claw 407 and the mounting plate 404. When the welding claw 407 moves along the range of the waist hole 410, it will not be interfered by the mounting plate 404.

[0048] The welding claw 407 is attached to the outside of the rebound connector 403 in the vertical direction. The rebound connector 403 is a bent baffle. When the welding claw 407 is pushed to a vertical state by the steel cage 7, it is squeezed onto the rebound connector 403. When the steel cage 7 is lowered, the rebound connector 403 can quickly restore the welding claw 407 without affecting continued use.

[0049] The working principle of the claw mechanism 4 is as follows: the weld claw 407 can swing along the range of the waist hole 410. When the edges of the steel cage 7 are all neatly cut ports, the weld claw 407 naturally stops at the position where the steel cage 7 is cut. Figure 13 In the position shown, the edge of the reinforcement cage can be hooked and placed on the upper end of the weldment gripper 407;

[0050] When the edge of the steel cage 7 is artificial stirrups and its end is irregular, the edge of the irregular steel cage 7 first contacts the rolling bar 408, and the rolling bar 408 squeezes the weldment claw 407 inward. Figure 11 and Figure 12 As shown, the welding claw 407 swings upward to a vertical state, so that the welding claw 407 here is not subjected to force and does not interfere with the normal work of other welding claws 407.

[0051] The locking mechanism 5 includes a fixed component and a movable component, which are adapted to be installed. The fixed component includes a connecting plate 501, a fixed plate 502 and an inductive proximity switch 503. The upper end of the connecting plate 501 is integrally provided with a fixed plate 502, and one side of the fixed plate 502 is provided with an inductive proximity switch 503; the movable component includes a swing cylinder 504, a sliding bearing 505, a push block 506, a hinge shaft 507 and a stop block 508. The lower end of the connecting plate 501 is fixedly installed with a cylinder mounting seat 509 The cylinder mounting seat 509 is adapted and fixed to the swing cylinder 504, and the output end of the swing cylinder 504 is adapted and connected to the sliding bearing 505. The sliding bearing 505 is connected to one end of the push block 506 through the fixed shaft 510. The other end of the push block 506 is provided with a hinge shaft 507. The hinge shaft 507 passes through the push block 506, the connecting plate 501, the stop block 508 and the fixed plate 502 from bottom to top, and the hinge shaft 507 is fixedly connected to the fixed plate 502, and the push block 506 and the stop block 508 rotate synchronously.

[0052] A positioning notch is provided at the lower end of the fixing plate 502 , and a stopper 508 is provided in the positioning notch. The width of the positioning notch is greater than that of the stopper 508 . An inductive proximity switch 503 is fixedly installed on one side of the positioning notch, and a gap is left between the inductive proximity switch 503 and the stopper 508 .

[0053] The working principle of the locking mechanism 5 is as follows: when the lifting cylinder 301 lifts the weight vertically, the proximity switch 503 senses the normal operation of the lifting cylinder 301, the swing cylinder 504 retracts and pulls the push block 506 back, and simultaneously drives the stop block 508 back into the positioning notch without affecting the normal operation of the lifting cylinder 301;

[0054] When the lifting cylinder 301 fails and falls, the induction proximity switch 503 senses that its descending speed is abnormal, and drives the swing cylinder 504 to extend, pushing the push block 506 to synchronously drive the stop block 508 to extend under the lifting cylinder 301, timely blocking the sudden fall of the hook mechanism 4 lifted by the lifting cylinder 301, avoiding the occurrence of safety accidents, and effectively protecting the output end of the lifting cylinder 301 and the hook mechanism 4 to avoid damage.

[0055] The diagonal bracing fixing mechanism 3 includes a lifting cylinder 301, a sway correction mechanism and a diagonal bracing mechanism. A lifting cylinder 301 is fixedly provided in the middle of the crossbeam 2. Both sides of the lifting cylinder 301 are provided with sway correction mechanisms. The back side of the sway correction mechanism is fixedly connected to the crossbeam 2. The front side of the sway correction mechanism is slidably connected to the diagonal bracing mechanism. The diagonal bracing mechanism includes a vertical rod 302, a horizontal rod 303, a first diagonal rod 304 and a second diagonal rod 305. A horizontal rod 303 is fixedly installed between the vertical rods 302. A cross rod 303 is provided below the cross rod 303. The first diagonal rod 304 and the second diagonal rod 305 are fixed by a fork, and there are two second diagonal rods 305, and one end of the two second diagonal rods 305 is welded and fixed to the midpoint of the first diagonal rod 304 respectively. The first diagonal rod 304 and the second diagonal rod 305 are both fixedly connected to the vertical rod 302, and the lower end of the vertical rod 302 and the output end of the lifting cylinder 301 are fixedly connected to the lifting frame 401 respectively. The cross bar 303, the first diagonal rod 304 and the second diagonal rod 305 form a triangle to enhance the stability of the diagonal support fixing mechanism 3.

[0056] The yaw correction mechanism includes a correction base plate 306, a support plate 307, a correction component and a slider 308. The back side of the correction base plate 306 is fixed on the crossbeam frame 2, and the support plate 307 and the slider 308 are fixedly installed on the front side of the correction base plate 306. The correction component is fixed on the outer side of the support plate 307, and the correction component is pressed on the front side of the vertical rod 302. The back side of the vertical rod 302 is provided with a guide rail 314, and the slider 308 is adaptively connected to the guide rail 314.

[0057] The correction component includes a guide block 309, a large pressure wheel 311, a small pressure wheel 312 and a correction wheel shaft 313. An adjustment groove 310 is opened on the inner side of the guide block 309, and multiple groups of correction wheel shafts 313 are passed through one side of the adjustment groove 310. The two ends of the correction wheel shaft 313 are coaxially rotatably connected to the large pressure wheel 311 and the small pressure wheel 312 respectively. The outer diameter of the large pressure wheel 311 extends out of the outer surface of the guide block 309, and the surface of the large pressure wheel 311 is against the front of the vertical rod 302. A gap is left between the small pressure wheel 312 and the vertical rod 302. Specifically, in actual use, the large pressure wheel 311 and the small pressure wheel 312 correspond to each other, and there are at least three groups. Three groups are shown in the drawings of this embodiment.

[0058] The working principle of the diagonal support fixing mechanism 3 is: when the lifting cylinder 301 is extended or retracted, the diagonal support mechanism moves along the direction of the guide rail 314, safely and effectively lifting the steel cage 7 required by the weldment clamp 407, and the yaw correction mechanism eliminates the eccentric load torque generated by the slider 308 during the movement, effectively maintaining the service life of the slider 308.

[0059] The overall working principle of the present invention is as follows: the conveyor belt 6 receives the steel cage 7 transmitted from the previous station, and adjusts the crossbeam frame 2 on the side of the sliding connection with the mounting frame 1 so that the hook mechanism 4 at the lower end of the crossbeam frame 2 on the side of the sliding connection is slightly close to the end of the steel cage 7;

[0060] The lifting cylinder 301 extends, driving the hook mechanism 4 to descend. The lower end of the hook mechanism 4 descends to the middle of the steel cage 7. The crossbeam frame 2, which is slidably connected to the mounting frame 1, continues to move inward, completely containing the steel cage 7 within the two opposing hook mechanisms 4.

[0061] The lifting cylinder 301 is retracted in an orderly manner, and the weld claws 407 are hooked to the ends of the steel cage 7, and the steel cage 7 is smoothly lifted up. The mesh conveying mechanism then puts the steel mesh at the bottom (not shown in the figure), and the lifting cylinder 301 is extended again, driving the lifted steel cage 7 to descend and reset.

[0062] The entire steel cage lifting process is fully automated and can be compatible with steel cages of different heights and widths for effective lifting. Its locking mechanism 5 protects the safety of operators and equipment. The steel cage 7 is relatively stable during the lifting process, and the hook mechanism 4 can effectively hook the edge of the entire steel cage 7.

[0063] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of rights of the present invention. Therefore, modifications, equivalent changes, improvements, etc. made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
