DETAILED DESCRIPTION

[0039] The present invention will be further described below in conjunction with the accompanying drawings:

[0040] The directional nouns involved in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application according to the visual orientation shown in the accompanying drawings. Unless otherwise clearly specified and limited, the terms "setting", "installation", "connection", etc. should be understood in a broad sense. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0041] like Figures 1 to 6 As shown, a steel beam lifting device for assembling a steel structure workshop comprises: a lifting platform 100, a climbing device 200, a pushing device 300, a self-fixing device 400, and a driving device 500, characterized in that: a plurality of slideways 101 adapted to the partial structure of the pushing device 300 are provided on one side of the lifting platform 100, and a rack rail 102 and a plurality of slide bars 104 are provided on the other side, and are adapted to be connected with the driving device 500; the climbing device 200 is installed on one side of the lifting platform 100, located on both sides of the slide bar 104; the pushing device 300 is arranged adjacent to the climbing device 200, and comprises a traction assembly 310, a claw assembly 320, wherein the claw assembly 320 20 is movably arranged in the slide 101 and is movably connected to the traction assembly 310 on the other side of the lifting platform 100; the self-fixing device 400 is installed on the side of the traction assembly 310 away from the climbing device 200, and is movably connected to the lifting platform 100, and part of the structure extends to the outside of the lifting platform 100 and is connected to the fastening assembly 410; the driving device 500 is adaptively connected to the rack 102 and the slide bar 104, and is movably arranged between the climbing device 200, the pushing device 300, and the self-fixing device 400, and moves to a specific position in a sliding manner to engage with the climbing device 200 or the pushing device 300 or the self-fixing device 400, and engages with the driving device.

[0042] Optionally, an embedding groove 103 is provided on the opposite side wall of the lifting platform 100. In this way, the self-fixing device 400 can extend to the inner side of the lifting platform 100 through the embedding groove 103, and the self-fixing device 400 can also slide telescopically along the embedding groove 103.

[0043] Optionally, a special-shaped through groove is provided on one side of the lifting platform 100, which is adapted to the climbing device 200. In this way, the lifting platform 100 and the climbing device 200 are connected to each other through the special-shaped through groove, and the movement of the climbing device 200 is not affected.

[0044] Optionally, a plurality of sets of bearing seats 105 are fixed to one side of the lifting platform 100, and the bearing seats 105 are connected to both ends of the slide bar 104. In this way, the slide bar 104 is supported by the bearing seats 105, so that a certain distance is left between the slide bar 104 and the lifting platform 100.

[0045] like Figures 6 to 8As shown, the climbing device 200 includes a linkage box 210, a rotating shaft 220, a fixing buckle 221, a linkage gear 222, a climbing gear 223, and a bracket 230. The linkage box 210 is provided with a plurality of linkage boxes, which are fitted with the side wall of the lifting platform 100. The rotating shaft 220 is rotatably embedded in the top of the linkage box 210, with a linkage gear 222 fixed at one end and a climbing gear 223 fixed at the other end, and the climbing gear 223 extends into the linkage box 210. Among them, one end of the rotating shaft 220 equipped with the linkage gear 222 is rotatably connected to the bracket 230 fixed on the lifting platform 100. In this way, the linkage gear 222 is meshed with the driving device 500, thereby driving the rotating shaft 220 and the climbing gear 223 connected in series with the linkage gear 222 to rotate synchronously. The rotating shaft 220 is fixed and limited by the cooperation of the fixing buckle 221 and the bracket 230, which reduces the possibility of the rotating shaft 220 being offset or disengaged during the rotation process, and effectively improves the working stability of the rotating shaft 220, the linkage gear 222, and the climbing gear 223.

[0046] like Figure 8 As shown, the linkage box 210 is provided with a climbing groove 211, and a plurality of auxiliary wheels 212 are embedded on one side of the climbing groove 211; at the same time, a slot 213 adapted to the climbing gear 223 is provided on the side wall facing the climbing groove 211, and the climbing groove 211 is connected to the slot 213. In this way, the auxiliary wheels 212 arranged in the climbing groove 211 can reduce the friction of the linkage box 210 during the climbing process of the lifting platform 100, thereby extending the service life of the linkage box 210 and the lifting platform 100. On the other hand, the inner diameter of the climbing groove 211 can be reduced by the auxiliary wheels 212, so that the linkage box 210 can be more closely connected to the climbing object.

[0047] Optionally, the outer peripheral wall of the auxiliary wheel 212 is made of rubber material. In this way, the rubber material has good flexibility, and when the inner diameter of the climbing groove 211 is smaller than the climbing object, the climbing object can still pass through the climbing groove 211 by virtue of its flexibility. Thus, the firmness of the connection between the linkage box 210 and the climbing object is improved.

[0048] like Fig. 9 and Fig.10As shown, the traction assembly 310 is installed on one side of the climbing device 200, including a frame 311, a shaft 312, a driven gear 313, a winch wheel 314, a first guide wheel 315, a second guide wheel 316, and a cable 317. The winch wheel 314 is fixed at both ends of the shaft 312, and a driven gear 313 adapted to the driving device 500 is also installed on the shaft 312, adjacent to the winch wheel 314; the shaft 312 is rotatably connected to the frame 311 fixed to one side of the lifting platform 100; the first guide wheel 315 is provided with a plurality of groups, which are respectively installed on both sides of the frame 311; the second guide wheel 316 is fixed at both ends of the lifting platform 100, and is located below the end of the slideway 101; wherein the winch wheel 314, the first guide wheel 315, and the second guide wheel 316 are on the same straight line; a plurality of cables 317 are provided, one end of which is fixed to the winch wheel 314, and the other end of which is fixed to the claw assembly 320. In this way, when the driven gear 313 meshes and rotates with the driving device 500, it can drive the cable wheel 314 connected to the shaft 312 to rotate synchronously. Therefore, the cable 317 connected to the cable wheel 314 is synchronously wound and released under the rotation of the cable wheel 314, so as to pull the claw assembly 320 to slide along the slideway 101 in different directions. The cable wheel 314, the first guide wheel 315, and the second guide wheel 316 arranged on the same straight line can guide the cable 317 when winding and releasing, so as to prevent the cable 317 from deviating from the original running track, thereby improving the stability of the traction assembly 310.

[0049] It can be understood that the cables 317 are fixedly connected to the winch wheel 314 in different directions, that is, one cable 317 passes through the first guide wheel 315 on one side of the frame 311 and contacts the second guide wheel 316 on the same side, and then is connected to one end of the claw assembly 320. The other cable 317 passes through the first guide wheel 315 on the other side of the frame 311 and contacts the second guide wheel 316 on the same side, and then is connected to the other end of the claw assembly 320. When the winch wheel 314 rotates clockwise, the cable 317 at one end is reeled in, pulling the claw assembly 320 to move toward one end of the lifting platform 100, and the other cable 317 connected thereto is released following the claw assembly 320. On the contrary, when the winch wheel 314 rotates counterclockwise, the two cables 317 move in opposite ways, pulling the claw assembly 320 to move toward the other end of the lifting platform 100.

[0050] like Figures 11 to 13As shown, the claw assembly 320 includes a slider 321, a connecting seat 330, and a claw 332. The slider 321 is provided with a slide groove 322 adapted to the slideway 101 on both sides; a groove 323 is provided on the top of the slider 321; the connecting seat 330 is detachably fixed to the top of the slider 321, and part of the structure is embedded in the groove 323; the claw 332 is hinged on the top of the connecting seat 330 and rotates toward one side; wherein the connecting seat 330 can be connected to the slider 321 in reverse. In this way, the connecting seat 330 is a semi-enclosed structure, that is, only one end is provided with an opening. When an object moves from the opening direction toward the other end, the claw 332 will be continuously squeezed. At this time, during the squeezing process of the claw 332, the upper part of the claw 332 will automatically flip toward the moving direction of the object to prevent the claw 332 from hindering the movement of the object; when the object passes over the claw 332, the claw 332 will automatically return to its initial state. When the object moves in the opposite direction, since only one end of the connecting seat 330 is provided with an opening, the claw 332 is blocked by the other end of the connecting seat 330. Therefore, even if the claw 332 is squeezed by the object, it will not flip, so that the claw 332 can hook the object and push the object to the designated position under the drive of the winding wheel 314. On the contrary, if the object needs to be pushed to the other end, it only needs to remove the mounting seat in advance and install it in the opposite direction. Thereby, the flipping direction of the claw 332 is changed, and the object can be hooked and moved toward the other end.

[0051] Optionally, the top of the connecting seat 330 is provided with hinged ears 331 arranged opposite to each other, and a hinge rod is embedded between the hinged ears 331. In this way, the claw 332 can be movably installed between the hinged ears 331 through the hinge rod, so that the claw 332 can be flexibly turned over, thereby improving the stability of the turning of the claw 332.

[0052] Optionally, buckles 324 are installed at both ends of the slider 321. In this way, the slider 321 can be connected to the cable 317 through the slider 321.

[0053] like Fig.14 and Fig.15As shown, the self-fixing device 400 includes a telescopic joint 401, an inner connecting rod 402, a tooth plate 403, and an outer connecting rod 404. The telescopic joint 401 is symmetrically connected to the side wall of the lifting platform 100, and one end located in the lifting platform 100 is connected to the inner connecting rod 402; the tooth plate 403 is fixed to one side of the inner connecting rod 402 and meshed with the driving device 500; the outer connecting rod 404 is sleeved and fixed to the other end of the telescopic joint 401, and the other end of the outer connecting rod 404 is connected to the fastening assembly 410. In this way, after the tooth plate 403 is meshed with the driving device 500, the tooth plate 403 moves toward or in the opposite direction under the drive of the driving device 500. Through the inner connecting rod 402, the telescopic joint 401, and the outer connecting rod 404 connected to each other, the fastening assembly 410 installed at the end of the outer connecting plate is driven to move toward or away from the lifting platform 100.

[0054] like Fig.16 and Fig.17As shown, the fastening assembly 410 includes an upper clamping plate 411, a lower clamping plate 412, a connecting plate 413, an electric telescopic rod 414, a fastening wheel 415, a screwdriver 416, a fastening platform 417, a fastening motor 418, a fastening gear 419, a guide column 420, and a steel chain 421. The electric telescopic rod 414 is provided with at least two, both of which are embedded in the outer connecting rod 404; a plurality of connecting plates 413 adapted to the electric telescopic rod 414 are installed at one end of the upper clamping plate 411, and the connecting plates 413 are fixedly connected to the electric telescopic rod 414; a plurality of fastening wheels 415 and guide columns 420 are distributed on the top of the upper clamping plate 411, wherein one of the fastening wheels 415 The end of the clamping plate 412 extends to the bottom of the upper clamping plate 411 and is installed with a screwdriver bit 416; the fastening platform 417 is fixed to one side of the top of the upper clamping plate 411, and a fastening gear 419 is embedded in the inner side thereof; the fastening motor 418 is installed on the top of the fastening platform 417, and its power output end extends to the inside of the fastening platform 417 and is fixedly connected to the fastening gear 419; the lower clamping plate 412 is located below the upper clamping plate 411, and one end of the upper clamping plate 411 is installed with a plurality of connecting plates 413 adapted to the electric telescopic rod 414, and the connecting plates 413 are fixedly connected to the electric telescopic rod 414; the top of the lower clamping plate 412 is provided with an empty slot 422 adapted to the screwdriver bit 416. In this way, driven by the electric telescopic rod 414, the upper clamping plate 411 and the lower clamping plate 412 connected to the electric telescopic rod 414 through the connecting plates 413 enable the two to move synchronously in opposite directions or in reverse directions. When the upper clamping plate 411 and the lower clamping plate 412 move toward each other, the tightening wheel 415 and the screwdriver bit 416 connected thereto rotate synchronously with the cooperation of the tightening motor 418, the tightening gear 419 and the steel chain 421 until they stop when they move to a specific position between the upper clamping plate 411 and the lower clamping plate 412. In addition, a screw is embedded in the screwdriver bit 416, and a nut adapted to the screw is embedded in the empty groove 422. With the opposite movement of the upper clamping plate 411 and the lower clamping plate 412 and the rotation of the screwdriver bit 416, the screw can connect with the nut by itself and complete the tightening.

[0055] Optionally, the screwdriver bit 416 and the empty slot 422 are both detachable structures. In this way, screwdriver bits 416 of different specifications and the corresponding empty slots 422 can be selected according to actual work needs, so as to adapt and connect the screw rod and the nut, which effectively improves the applicability of the device.

[0056] Optionally, a magnet is fixed in the screwdriver bit 416. In this way, the screw can be fixed in the screwdriver bit 416 by the magnet, so that it is not easy to fall off during the movement of the device. In addition, the screw is fixed in the screwdriver bit 416 by the magnet, so that after the screw is tightened, it will automatically separate from the screwdriver bit 416 during the separation process of the upper clamping plate 411 and the lower clamping plate 412, and no other operations are required.

[0057] Optionally, a magnet is fixed in the empty slot 422. In this way, it has the same function as the magnet fixed in the screwdriver bit 416, and is used to fix the nut, and no further description is given.

[0058] like Fig.18 and Fig.19 As shown, the side wall of the driving device 500 is provided with a rectangular through slot 501 adapted to the rack 102 and a circular through slot 502 adapted to the slide bar 104; a sliding motor 510 is installed on one side of the driving device 500, and a sliding gear 511 adapted to the rack 102 is installed on the power output end of the sliding motor 510; driving gears 505 are installed on the power output ends of both ends of the driving device 500. In this way, through the cooperation of the rectangular through slot 501 and the circular through slot 502, the driving device 500 can make a straight line reciprocating motion along the rack 102 and the slide bar 104, effectively avoiding the occurrence of deviation or separation of the driving device 500 during the sliding process, and ensuring the stability of the operation of the driving device 500. At the same time, the driving device 500 can run to a predetermined position under the cooperation of the sliding motor 510 and the sliding gear 511, so as to achieve the purpose of driving the climbing device 200, the pushing device 300 and the self-fixing device 400 to run respectively.

[0059] Optionally, an extension plate 503 connected to the driving device 500 is fixed between the rectangular through slot 501 and one of the circular through slots 502. In this way, the sliding motor 510 can be fixed on the extension plate 503, so that the sliding motor 510 can move synchronously with the driving device 500.

[0060] Optionally, a hinge plate 504 is further provided on the side wall of the driving device 500, which is in the same straight line as the power output end of the sliding motor 510 and the sliding gear 511, and the end of the sliding gear 511 away from the sliding motor 510 is rotatably connected to the hinge plate 504. In this way, the hinge plate 504 is provided to limit the sliding gear 511, thereby preventing the sliding gear 511 from jumping due to excessive torque when meshing with the rack 102. This allows the sliding gear 511 to maintain a tight meshing connection with the rack 102, thereby ensuring the stability of the operation of the sliding gear 511.

[0061] like Fig. 20As shown, it also includes a standard section 600 and a climbing rail 700. The standard section 600 includes a first frame 601 and a second frame 602. The two have the same structure and are arranged opposite to each other and spliced ​​into a whole. At the same time, both are composed of a support column 610, a first flange 611, a crossbeam 620, a diagonal brace 621, and a second flange 622. The first frame 601 and the second frame 602 each include two parallel support columns 610, and the support columns 610 are connected with a crossbeam 620 and a diagonal brace 621; both ends of the support columns 610 are fixed with a first flange 611; the ends of the crossbeam 620 and the diagonal brace 621 of the first frame 601 and the second frame 602 that are arranged opposite to each other are fixed with a second flange 622; the climbing rail 700 is fixed on one side of each support column 610. In this way, after the first frame 601 and the second frame 602 are butted against each other, the second flanges 622 provided on the cross beams 620 and diagonal braces 621 of the two frames are fixed, so that the first frame 601 and the second frame 602 form a complete standard section 600. At the same time, multiple standard sections 600 are stacked and connected in sequence from top to bottom, and the first flanges 611 provided thereon are butted against each other and aligned, and fixed by a fastening device.

[0062] Optionally, when two standard sections 600 are superimposed and connected, their first flanges 611 abut against each other and are aligned. The driving device 500 moves to a specified position, meshes with the rack of the self-tightening device, and drives the fastening assembly 410 to move toward the flange. When the fastening assembly 410 moves to a specified position, the screws and nuts are distributed perpendicular to the threaded holes on the flange. Driven by the fastening device, each screw aligned with the threaded hole is rotated and sequentially passed through the superimposed first flange 611 and fastened to the nut. Thereby achieving the purpose of completing the fastening of multiple screws at the same time, effectively improving the working efficiency of the connection and fixation of the standard section 600.

[0063] Optionally, a positioning notch is provided at the edge of the first flange 611. In this way, the positioning connection of the climbing rail 700 is facilitated, so that the climbing rail 700 can always be in a straight line after installation, and the lifting platform 100 is convenient to move up or down along the climbing rail 700.

[0064] Exemplarily, the outer sides of the first frame 601 and the second frame 602 are both installed with a lifting platform 100, and are used to transport the first frame 601 or the second frame 602 respectively. When the first frame 601 or the second frame 602 is transported, the first frame 601 or the second frame 602 is placed on the surface of the lifting platform 100, and the bottom crossbeam 620 of the first frame 601 or the second frame 602 is connected with the claw 332 to ensure that the first frame 601 or the second frame 602 remains stable during the lifting process, so that it is not easy to fall off. When the lifting platform 100 is driven by the climbing device 200 to run to the top of the first flange 611, it stops automatically. At this time, the climbing device 200 is locked by itself, and the driving device 500 moves to the preset position to engage with the pushing device 300, and drives the winch wheel 314 to rotate, so that the claw 332 pushes the first frame 601 and the second frame 602 to move in a counter manner until the second flanges 622 of the two are abutted and fixed to each other. At this time, the two vertically stacked first flanges 611 are aligned with each other, the driving device 500 is separated from the driving device 500, moved to a predetermined position to engage with the self-fixing device 400, and drives the upper clamping plate 411 and the lower clamping plate 412 of the fastening device to move above and below the two overlapping first flanges 611, so that the fastening device can fasten the two flanges by itself. Then, the driving device 500 is separated from the self-fastening device, moves toward the climbing device 200, and engages with the climbing device 200, driving the climbing device 200 to move downward along the climbing rail 700 until it lands on the ground, and performs loading work on the first frame 601, the second frame 602, the screw, and the nut.

[0065] On the contrary, if the first frame 601 and the second frame 602 need to be disassembled, the connection seat 330 equipped with the claw 332 needs to be removed and installed in reverse. After the preliminary work is completed, the driving device 500 drives the climbing device 200 to move the lifting platform 100 to the specified position, and the driving device 500 drives the claw 332 of the pushing device 300 to move toward the first frame 601 or the second frame 602. When the claw 332 abuts against the first frame 601 and the second frame 602, the claw 332 folds itself under the action of the extrusion force. When the claw 332 moves to the other side of the first frame 601 or the second frame 602, the claw 332 recovers itself and abuts against the crossbeam 620 of the first frame 601 or the second frame 602. Then, the driving device 500 engages with the self-tightening device, so that the upper clamping plate 411 and the lower clamping plate 412 of the fastening assembly 410 are connected to the screw and the nut respectively, and rotate in the opposite direction to separate the screw and the nut. After removing the screws and nuts on the first flange 611 and the second flange 622, the driving device 500 returns to the engagement position of the pushing device 300 again, and pulls the first frame 601 or the second frame 602 to the surface of the lifting platform 100. Finally, the driving device 500 drives the lifting platform 100 to fall back to the ground position, thereby completing the disassembly of one standard section 600.

[0066] like Fig.21 As shown, the climbing rail 700 is adapted to be connected with the climbing groove 211, and the side of the climbing rail 700 facing away from the support column 610 is provided with climbing teeth 710 adapted with the climbing gear 223; the side of the climbing rail 700 facing the support column 610 is fixed with equidistantly arranged fixing rings 720 and embedded rings 730, wherein one side of the embedded ring 730 abuts against the first flange 611. In this way, through the provided fixing rings 720 and embedded rings 730, not only the lateral connection force between the climbing rail 700 and the support column 610 is enhanced, but also the longitudinal compressive resistance between the climbing rail 700 and the support column 610 is improved, thereby ensuring that the lifting platform 100 can stably perform lifting and lowering motion under the drive of the climbing device 200, and effectively improving the stability of the device operation.

[0067] Optionally, an alignment protrusion adapted to the alignment notch is provided on the inner wall of the embedded ring 730 .

[0068] Finally, although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
