Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and in particular to a plate unit anti-deformation assembly and disassembly machine based on a floating top frame beam. Background Technology

[0002] The steel box girder bridge deck structure currently used in bridges consists of plate units, which include longitudinal ribs and steel panels. During the manufacturing of plate units, the webs on both sides of the longitudinal ribs need to be welded to the steel panels along longitudinal corner seams. The longitudinal ribs are generally U-ribs (U-shaped rib plates). U-ribs are slender and narrow, typically exceeding 12 meters in length. Welding such extra-long plate units usually involves using two or more jigs to support an extra-long welding jig as a welding platform. Because plate unit welding is prone to warping and deformation, affecting the subsequent use of the workpiece, a reverse deformation welding process is required before welding the plate units.

[0003] Welding of plate units typically involves hoisting them onto a jig. Current technology for anti-deformation pretreatment of plate units primarily uses separate clamping equipment for this purpose. Two rows of hydraulic clamping devices are arranged on both sides of the plate unit where it contacts the jig for pre-compression. The multiple hydraulic cylinders applying pressure and fixed to the jig occupy a significant amount of space, which can substantially impact subsequent welding processes.

[0004] Patent CN216462632U discloses a plate unit anti-deformation welding jig mounting and disassembly machine of our company. It adopts the use of safety hooks to reduce the impact on the track. However, in actual use, the horizontal height of the lowest surface of the welding jig to be welded is not flat. This difference in height may be tens of millimeters. As a result, during the anti-deformation process, the entire gantry is lifted up by the hydraulic cylinder to compensate for the height difference between the safety hook and the welding jig, which may lead to the risk of derailment and affect production safety. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this invention provides a plate unit anti-deformation assembly and disassembly machine based on a floating top frame beam. The technical solution adopted is as follows:

[0006] The plate unit anti-deformation assembly and disassembly machine based on a floating top frame beam includes a movable gantry mechanism and a floating top frame beam anti-deformation mechanism. The movable gantry mechanism includes a gantry and a traveling mechanism. The traveling mechanism is located at the bottom of the gantry and provides the ability to move on tracks. Multiple floating track plates are set on the gantry. The floating top frame beam anti-deformation mechanism includes a floating frame beam, multiple floating guide devices, and multiple sets of floating anti-deformation devices. The floating frame beam is set between the multiple floating track plates through multiple floating guide devices on all four sides and moves freely up and down under the guidance of the floating guide devices. Multiple sets of floating anti-deformation devices are respectively set on both sides of the bottom of the floating frame beam and move up and down with the floating frame beam to provide anti-deformation clamping for the plate unit.

[0007] By adopting the above technical solution, in order to solve the risk of the gantry being lifted upwards by the hydraulic cylinder during the anti-deformation process, causing the traveling mechanism to disengage, a floating top frame beam anti-deformation mechanism is designed. When multiple sets of floating anti-deformation devices reach the anti-deformation position, the reaction force caused by the anti-deformation pre-compression exists only between the floating frame beam, the safety hook, and the welding jig, changing the original external force into an internal force. The floating frame beam is assembled between multiple floating track plates through multiple floating guide devices. In this way, the up and down floating of the floating frame beam will not affect the normal state of the gantry, thereby avoiding the risk of the gantry derailing. It can be applied to the anti-deformation process before welding of plate units of different specifications.

[0008] Optionally, the floating guide device includes a guide wheel mounting plate and a guide wheel. One side of the guide wheel mounting plate is fixedly installed on the outer side of the floating frame beam, and the base of the guide wheel is fixedly installed on the other side of the guide wheel mounting plate.

[0009] By adopting the above technical solution, the floating guide device is based on the guide wheel. When the deformation caused by the floating anti-deformation device applying anti-deformation pressure to the plate unit is fed back to the floating frame beam during operation, the floating frame beam will move up and down. Due to the presence of the guide wheel, the floating frame beam will move relative to the gantry, thus not affecting the normal state of the gantry and avoiding the risk of the gantry derailing.

[0010] Optionally, the floating guide device further includes a bottom limiting beam and a top limiting beam assembly. The bottom limiting beam is fixed to the bottom of the floating frame beam to limit the lowest descent position of the floating frame beam. The top limiting beam assembly includes multiple limiting blocks and a top limiting beam. The multiple limiting blocks are respectively fixedly installed on the top surface of the floating frame beam, and the top limiting beam is fixed to the top of the gantry to limit the highest rising point of the floating frame beam.

[0011] By adopting the above technical solution, the combined use of the bottom limiting beam and the top limiting beam assembly restricts the upper and lower limit positions of the floating frame beam. Before the reverse deformation pressing, the bottom limiting beam at the bottom of the floating frame beam is supported by the crossbeam on the gantry. During the reverse deformation process, the limiting block and the top limiting beam are set to limit the maximum upward movement of the floating frame beam, so as to avoid the irreversible damage to the plate unit caused by excessive reverse deformation due to excessive pressing.

[0012] Optionally, the floating anti-deformation device includes an anti-deformation vertical beam, an anti-deformation safety hook, and an anti-deformation clamping mechanism. The top of the anti-deformation vertical beam is mounted on the bottom surface of the floating frame beam. The anti-deformation safety hook is fixedly installed at the bottom of the anti-deformation vertical beam and hooks onto the bottom surface of the welding jig during the anti-deformation operation of the plate unit. The base of the anti-deformation clamping mechanism is installed on the bottom surface of the floating frame beam. The anti-deformation clamping mechanism is equipped with a telescopic rod. When the telescopic rod extends, it abuts against the upper surface of the plate unit to provide anti-deformation clamping force.

[0013] By adopting the above technical solution, during the reverse deformation process, the bearing surface of the reverse deformation safety hook contacts the bottom surface of the welding jig, and the end of the telescopic rod of the reverse deformation clamping mechanism extends and abuts against the upper surface of the plate unit. The telescopic rod of the reverse deformation clamping mechanism continues to extend and retract, which will perform reverse deformation pre-clamping on the plate unit. In this way, the deformation amount of the plate unit after full welding will meet the deformation amount required by the welding process. The bottom reaction force of the reverse deformation clamping mechanism acts on the floating frame beam, and the height difference between the safety hook and the bottom surface of the welding jig is compensated by the rise of the floating frame beam. During this process, the gantry is not subjected to external force, and the traveling mechanism always stays on the track, solving the previous derailment problem.

[0014] Optionally, the anti-deformation pressing mechanism is installed on the bottom surface of the floating frame beam via a position adjustment device. The position adjustment device includes a mounting base, four position adjustment wheel mounting bases, and four position adjustment wheels. The bottom surface of the mounting base is assembled and connected with the base of the anti-deformation pressing mechanism. The four position adjustment wheel mounting bases are respectively installed on the top surface of the mounting base. A deformation pressing mechanism hanger beam is provided on the floating frame beam. The four position adjustment wheels are rotatably installed on the four position adjustment wheel mounting bases via rotating shafts, and the wheel rims of the adjustment wheel mounting bases can move left and right on the deformation pressing mechanism hanger beam.

[0015] By adopting the above technical solution, the position adjustment device is set to make the position of the floating anti-deformation device adjustable. The floating anti-deformation device is generally used in pairs, with the left and right sides corresponding to the two sides of the plate unit respectively. Before the anti-deformation process, the anti-deformation clamping mechanism can be moved by the left and right position adjustment device. When moving, the four position adjustment wheels move left and right on the hanging beam of the deformation clamping mechanism. After the movement is completed, the reverse force of the anti-deformation clamping mechanism during the anti-deformation process makes the upper surface of the mounting base directly contact the bottom surface of the hanging beam of the deformation clamping mechanism, avoiding movement and ensuring safety and reliability.

[0016] Optionally, the position adjustment device also includes a pair of lateral limiting blocks, which are respectively disposed on the top surface of the mounting base and located on both sides of the position adjustment wheel mounting base to limit the lateral movement of the position adjustment wheel mounting base.

[0017] By adopting the above technical solution, the setting of a pair of lateral limiting blocks can prevent the anti-deformation clamping mechanism from deviating when it moves left and right to adjust its position.

[0018] Optionally, the anti-deformation safety hook is provided with a bearing surface, and an anti-slip plate is provided on the bearing surface. The upper surface of the anti-slip plate is used to support the plate unit.

[0019] By adopting the above technical solution, the anti-slip plate can prevent uncontrollable displacement between the bearing surface of the anti-deformation safety hook and the bottom surface of the plate unit during the anti-deformation process, thereby increasing the safety guarantee of the anti-deformation process.

[0020] Optionally, the anti-deformation clamping mechanism includes a hydraulic station, an anti-deformation hydraulic cylinder, and an anti-deformation pressure block. The base of the anti-deformation hydraulic cylinder is installed on the bottom surface of the floating frame beam, and the piston rod end of the anti-deformation hydraulic cylinder faces downward. The anti-deformation pressure block is installed on the piston rod end of the anti-deformation hydraulic cylinder and moves up and down with the piston rod. The hydraulic station is set on the top surface of the floating frame beam and is connected to the anti-deformation hydraulic cylinder through a hydraulic control element to provide hydraulic pressure. When the bottom surface of the anti-deformation pressure block abuts against the upper surface of the plate unit, the hydraulic control element continues to provide hydraulic pressure to achieve anti-deformation of the plate unit before welding.

[0021] By adopting the above technical solution, the hydraulic station provides hydraulic pressure to the anti-deformation hydraulic cylinder. The combination of the anti-deformation hydraulic cylinder and the anti-deformation pressure block can efficiently achieve the anti-deformation of the plate unit before welding under the control of the hydraulic control components.

[0022] Optionally, the traveling mechanism includes multiple pairs of traveling wheel mechanisms and a traveling drive motor. The multiple pairs of traveling wheel mechanisms are mounted on the bottom of the gantry and travel on the track. The traveling drive motor is mounted on the gantry, and the power shaft drives the traveling wheel mechanisms to move on the track through a transmission device.

[0023] By adopting the above technical solution, the traveling mechanism provides the gantry with the power to move, so that the gantry moves on the track, which can be used in conjunction with the plate unit conveying system to realize the reverse deformation process at different process requirements.

[0024] In summary, the present invention has at least one of the following beneficial technical effects:

[0025] This invention provides a plate unit anti-deformation assembly and disassembly machine based on a floating top frame beam. The floating top frame beam anti-deformation mechanism is assembled onto a gantry to realize the anti-deformation process of the plate unit. This solves the risk of gantry derailment in the anti-deformation process of the existing plate unit anti-deformation assembly and disassembly machine. It is safe and reliable. The position of the anti-deformation clamping mechanism can also be adjusted by a position adjustment device. It is suitable for anti-deformation processes of plate units with different widths.

[0032] The present invention will be further described in detail below with reference to the accompanying drawings.

[0033] This invention discloses a plate unit anti-deformation assembly and disassembly machine based on a floating top frame beam.

[0034] Reference Figure 1 - Figure 5 Example 1: A plate unit anti-deformation assembly and disassembly machine based on a floating top frame beam includes a movable gantry mechanism and a floating top frame beam anti-deformation mechanism. The movable gantry mechanism includes a gantry 1 and a traveling mechanism 2. The traveling mechanism 2 is located on the top of the gantry 1 and provides the ability to move on the track. Multiple floating track plates 11 are set on the gantry 1. The floating top frame beam anti-deformation mechanism includes a floating frame beam 3, multiple floating guide devices 4, and multiple sets of floating anti-deformation devices 5. The floating frame beam 3 is set between multiple floating track plates 11 through multiple floating guide devices 4 around its four sides and moves freely up and down under the guidance of the floating guide devices 4. Multiple sets of floating anti-deformation devices 5 are respectively set on both sides of the bottom of the floating frame beam 3 and move up and down with the floating frame beam 3 to provide anti-deformation clamping for the plate unit.

[0035] To address the risk of the gantry crane being lifted upwards by the hydraulic cylinders during the anti-deformation process, causing the traveling mechanism to disengage, a floating top frame beam anti-deformation mechanism is designed. When multiple floating anti-deformation devices 5 reach the anti-deformation position, the reaction force caused by the anti-deformation pre-compression exists only between the floating frame beam 3, the safety hook, and the welding jig, transforming the original external force into an internal force. The floating frame beam 3 is assembled between multiple floating track plates 11 through multiple floating guide devices 4. In this way, the up-and-down movement of the floating frame beam 3 will not affect the normal state of the gantry crane 1, thereby avoiding the risk of the gantry crane 1 derailing. This design is applicable to the anti-deformation process before welding plate units of different specifications.

[0036] Example 2: The floating guide device 4 includes a guide wheel mounting plate 41 and a guide wheel 42. One side of the guide wheel mounting plate 41 is fixedly installed on the outer side of the floating frame beam 3, and the base of the guide wheel 42 is fixedly installed on the other side of the guide wheel mounting plate 41.

[0037] The floating guide device 4 is based on the guide wheel 42. During operation, when the deformation caused by the floating anti-deformation device 5 applying anti-deformation pressure to the plate unit is fed back to the floating frame beam 3, the floating frame beam 3 will move up and down. Due to the presence of the guide wheel 42, the floating frame beam 3 will move relative to the gantry 1, thus not affecting the normal state of the gantry 1 and avoiding the risk of the gantry 1 derailing.

[0038] In embodiment 3, the floating guide device 4 also includes a bottom limiting beam 6 and a top limiting beam assembly 7. The bottom limiting beam 6 is fixed to the bottom of the floating frame beam 3 to limit the lowest descent position of the floating frame beam 3. The top limiting beam assembly 7 includes multiple limiting blocks 71 and a top limiting beam 72. The multiple limiting blocks 71 are respectively fixedly installed on the top surface of the floating frame beam 3, and the top limiting beam 72 is fixed to the top of the gantry 1 to limit the highest point of the floating frame beam 3.

[0039] The combined use of the bottom limiting beam 6 and the top limiting beam assembly 7 restricts the upper and lower limit positions of the floating frame beam 3. Before the reverse deformation pressing, the bottom limiting beam 6 at the bottom of the floating frame beam 3 is supported by the crossbeam part on the gantry 1. During the reverse deformation process, the limiting block 71 and the top limiting beam 72 are set to limit the maximum upward movement of the floating frame beam 3, so as to avoid the excessive reverse deformation caused by excessive pressing, which would cause irreversible damage to the plate unit.

[0040] Example 4: The floating anti-deformation device 5 includes an anti-deformation vertical beam 51, an anti-deformation safety hook 52, and an anti-deformation clamping mechanism 53. The top of the anti-deformation vertical beam 51 is mounted on the bottom surface of the floating frame beam 3. The anti-deformation safety hook 52 is fixedly installed on the bottom of the anti-deformation vertical beam 51 and hooks the bottom surface of the welding jig of the bearing plate unit during the anti-deformation operation of the plate unit. The base of the anti-deformation clamping mechanism 53 is installed on the bottom surface of the floating frame beam 3. The anti-deformation clamping mechanism 53 is equipped with a telescopic rod. When the telescopic rod extends, it abuts against the upper surface of the plate unit to provide anti-deformation clamping force.

[0041] During the reverse deformation process, the bearing surface of the reverse deformation safety hook 52 contacts the bottom surface of the welding jig of the bearing plate unit. The end of the telescopic rod of the reverse deformation clamping mechanism 53 extends and abuts against the upper surface of the plate unit. The telescopic rod of the reverse deformation clamping mechanism 53 continues to extend and retract, which will perform reverse deformation pre-clamping on the plate unit. In this way, the deformation amount of the plate unit after full welding will meet the deformation amount required by the welding process. The bottom reaction force of the reverse deformation clamping mechanism 53 acts on the floating frame beam 3, and the height difference between the reverse deformation safety hook 52 and the bottom surface of the welding jig is compensated by the rise of the floating frame beam. During this process, the gantry 1 is not subjected to external force, and the traveling mechanism 2 always stays on the track, solving the problem of derailment.

[0042] In Example 5, the anti-deformation pressing mechanism 53 is installed on the bottom surface of the floating frame beam 3 via a position adjustment device. The position adjustment device includes a mounting base 541, four position adjustment wheel mounting bases 542, and four position adjustment wheels 543. The bottom surface of the mounting base 541 is assembled and connected with the base of the anti-deformation pressing mechanism 53. The four position adjustment wheel mounting bases 542 are respectively installed on the top surface of the mounting base 541. A deformation pressing mechanism hanging beam 31 is provided on the floating frame beam 3. The four position adjustment wheels 543 are rotatably installed on the four position adjustment wheel mounting bases 542 via rotating shafts, and the wheel rims of the adjustment wheel mounting bases 542 can move left and right on the deformation pressing mechanism hanging beam 31.

[0043] The position adjustment device is set up so that the position of the floating anti-deformation device 5 can be adjusted. The floating anti-deformation device 5 is generally used in pairs, with the left and right sides corresponding to the two sides of the plate unit respectively. Before the anti-deformation process, the anti-deformation clamping mechanism 53 can be moved by the left and right position adjustment device. When moving, the four position adjustment wheels 543 move left and right on the deformation clamping mechanism hanging beam 31. After the movement is completed, the reverse force of the anti-deformation clamping mechanism 53 during the anti-deformation process makes the upper surface of the mounting base 541 directly contact the bottom surface of the deformation clamping mechanism hanging beam 31, avoiding movement and ensuring safety and reliability.

[0044] In embodiment 6, the position adjustment device further includes a pair of lateral limiting blocks 544, which are respectively disposed on the top surface of the mounting base 541 and located on both sides of the position adjustment wheel mounting base 542, for limiting the lateral movement of the position adjustment wheel mounting base 542.

[0045] The pair of lateral limit blocks 544 can prevent the anti-deformation clamping mechanism 53 from deviating when it moves left and right to adjust its position.

[0046] Example 7: The anti-deformation safety hook 52 is provided with a bearing surface, and an anti-slip plate 521 is provided on the bearing surface. The upper surface of the anti-slip plate 521 is used to support the plate unit.

[0047] The anti-slip plate 521 can prevent uncontrollable displacement between the bearing surface of the anti-deformation safety hook 52 and the bottom surface of the plate unit during the anti-deformation process, thereby increasing the safety of the anti-deformation process.

[0048] Example 8: The anti-deformation clamping mechanism 53 includes a hydraulic station 531, an anti-deformation hydraulic cylinder 532, and an anti-deformation pressure block 533. The base of the anti-deformation hydraulic cylinder 532 is installed on the bottom surface of the floating frame beam 3. The piston rod end of the anti-deformation hydraulic cylinder 532 faces downward. The anti-deformation pressure block 533 is installed on the piston rod end of the anti-deformation hydraulic cylinder 532 and moves up and down with the piston rod. The hydraulic station 531 is set on the top surface of the floating frame beam 3 and is connected to the anti-deformation hydraulic cylinder 532 through a hydraulic control element to provide hydraulic pressure. When the bottom surface of the anti-deformation pressure block 533 abuts against the upper surface of the plate unit, the hydraulic control element continues to provide hydraulic pressure to achieve anti-deformation of the plate unit before welding.

[0049] The hydraulic station 531 provides hydraulic pressure to the anti-deformation hydraulic cylinder 532. The combination of the anti-deformation hydraulic cylinder 532 and the anti-deformation pressure block 533, under the control of the hydraulic control components, can efficiently achieve anti-deformation of the plate unit before welding.

[0050] In embodiment 9, the walking mechanism 2 includes multiple pairs of walking wheel mechanisms 21 and a walking drive motor 22. The multiple pairs of walking wheel mechanisms 21 are assembled at the bottom of the gantry frame 1 and walk on the track. The walking drive motor 22 is mounted on the gantry frame 1, and the power shaft drives the walking wheel mechanisms 21 to move on the track through a transmission device.

[0051] The traveling mechanism 2 provides the moving power for the gantry 1, enabling the gantry 1 to move on the track. It can work with the plate unit conveying system to achieve reverse deformation processes at different process requirements.

[0052] The implementation principle of the plate unit anti-deformation assembly and disassembly machine based on the floating top frame beam in this embodiment of the invention is as follows:

[0053] In specific anti-deformation application scenarios, the walking drive motor 22 drives the walking wheel mechanism 21 to move on the track, so that the gantry 1 spans above the plate unit to be welded. The anti-slip plate 521 on the bearing surface of the anti-deformation safety hook 52 is located at the pressing point set in the anti-deformation process of the plate unit. The position of the anti-deformation pressing mechanism 53 is adjusted by the position adjustment device so that the paired anti-deformation pressing mechanisms 53 match the width of the plate unit. The piston rod of the anti-deformation hydraulic cylinder 532 extends. The combined use of the anti-deformation hydraulic cylinder 532 and the anti-deformation pressing block 533, under the control of the hydraulic control components, can efficiently achieve the pressing of the plate unit. Before welding, the anti-deformation hydraulic cylinder 532 continues to extend and retract, which will pre-compress the plate unit by anti-deformation. In this way, the deformation amount of the plate unit after full welding will meet the deformation amount required by the welding process. The bottom reaction force of the anti-deformation compression mechanism 53 acts on the floating frame beam 3. Since the downward displacement of each pressing point is inconsistent, especially the displacement difference on both sides is large, the lifting amount of each corner of the floating frame beam 3 is inconsistent. Under the action of the floating guide device 4, the inconsistent lifting amount will not affect the normal state of the gantry 1.

[0054] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
