Description

Technical Field

[0001] This utility model relates to the field of plate unit welding technology, and in particular to a plate unit support frame. Background Technology

[0002] Plate units are core prefabricated components in modern steel structures (such as bridges and buildings), consisting of a panel and multiple ribs assembled by welding. The arrangement of the ribs (such as U-ribs and T-ribs) directly affects the fatigue performance and stability of the structure. For example, full penetration welding of U-ribs in orthogonal shaped plates of bridges can significantly improve fatigue resistance.

[0003] Currently, the main working method for internal welding of plate units is to first hoist the assembled and positioned plate units onto the assembly platform, and then insert multiple internal welding arms of the gantry-type internal welding machine through the holes in the middle of the fixed plate unit ribs to perform internal welding. However, the ribs of different plate units have different sizes and numbers. After installation, the existing jigs are only applicable to a single size of plate unit. When positioning plate units of different sizes, it is often necessary to disassemble multiple positioning columns and move and reinstall them to complete the production changeover, resulting in low production changeover efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a plate unit support frame. The technical solution is as follows: A plate unit support frame includes multiple fixed support beam assemblies, a support frame plate, and multiple plate unit lifting assemblies for assisting hoisting. The bottoms of the multiple fixed support beam assemblies are detachably installed on a precast foundation, and the tops form a support surface. The bottom of the support frame plate is detachably installed on the top surface of the multiple fixed support beam assemblies. Fixed positioning process holes and dynamic positioning process holes are respectively opened on the support frame plate at the positions corresponding to the multiple fixed support beam assemblies. The plate unit lifting assembly includes a lifting cylinder and a lifting column. The base of the lifting cylinder is detachably installed on the precast foundation, and the bottom of the lifting column is detachably installed on the piston rod end of the lifting cylinder. When the piston rod of the lifting cylinder extends or retracts, the lifting column extends and retracts at the lifting auxiliary process hole opened on the support frame plate.

[0005] Optionally, the plate unit position adaptive adjustment positioning device includes a fixed end positioning component and a moving end positioning component, which are detachably mounted on the fixed support beam component.

[0006] Optionally, the fixed end positioning assembly includes a fixed end telescopic cylinder and a fixed hook plate. The cylinder body of the fixed end telescopic cylinder is detachably mounted on the fixed support beam assembly. One end of the fixed hook plate is detachably mounted on the piston rod end of the fixed end telescopic cylinder and located in the fixed positioning process hole. When the piston rod of the fixed end telescopic cylinder retracts, the fixed hook plate fixes one side of the steel panel of the plate unit to be welded.

[0007] Optionally, the mobile end positioning component includes a mobile end linear guide, a mobile end telescopic cylinder, a mobile hook plate, and a lateral movement hydraulic cylinder. The mobile end linear guide and the lateral movement hydraulic cylinder are respectively mounted on the fixed support beam assembly. The cylinder body of the mobile end telescopic cylinder is detachably mounted on the slider of the mobile end linear guide. One end of the mobile hook plate is detachably mounted on the piston rod end of the mobile end telescopic cylinder and located within the dynamic positioning process hole. The piston rod of the lateral movement hydraulic cylinder is connected to the cylinder body of the mobile end telescopic cylinder. When the piston rod of the lateral movement hydraulic cylinder extends or retracts, it drives the mobile end telescopic cylinder to move linearly laterally on the track of the mobile end linear guide. At the same time, the mobile hook plate moves within the dynamic positioning process hole. The positional change between the mobile hook plate and the fixed hook plate matches the lateral dimensions of the plate units to be welded of different specifications.

[0008] Optionally, the unit position adaptive adjustment positioning device also includes a plate unit edge removal mechanism. The plate unit edge removal mechanism includes a reverse moving telescopic cylinder and a reverse moving hook plate. The reverse moving telescopic cylinder is detachably mounted on the fixed support beam assembly. One end of the reverse moving hook plate is mounted on the piston rod end of the reverse moving telescopic cylinder, and the other end is located in the fixed positioning process hole. When the piston rod of the reverse moving telescopic cylinder is in the initial position, the reverse moving hook plate is parallel to the fixed hook plate. When the piston rod of the reverse moving telescopic cylinder extends, the reverse moving hook plate separates one side of the plate unit to be welded from the fixed hook plate.

[0009] By adopting the above technical solution, the plate unit to be welded is roughly placed on the support frame plate by external hoisting equipment (such as a crane), so that its position roughly corresponds to the support surface formed by the fixed support beam assembly.

[0010] Then, the operator activates the plate unit lifting assembly. The piston rod of the lifting cylinder extends, driving the lifting column upward until it passes through the lifting auxiliary process hole opened on the support frame plate and presses against the bottom of the plate unit to be welded.

[0011] As the lifting column continues to rise, it lifts the plate unit to be welded slightly off the support surface of the supporting frame plate, creating a small gap between the plate unit and the supporting frame plate. At this point, the external hoisting equipment can release its hook.

[0012] The piston rod of the fixed-end telescopic cylinder retracts, causing the fixed hook plate to move inward. The fixed hook plate is designed to enter the fixed positioning process hole on the support jig plate and ultimately hook onto the steel panel on one side of the plate unit to be welded. This provides a fixed lateral positioning reference.

[0013] Operate the lateral movement hydraulic cylinder according to the specific lateral dimensions (width) of the plate unit to be welded.

[0014] The piston rod of the lateral moving hydraulic cylinder extends or retracts, driving the moving end telescopic cylinder and its mounted cylinder body to move laterally in a straight line along the moving end linear guide rail.

[0015] The piston rod of the movable telescopic cylinder retracts, causing the movable hook plate to move inward, allowing it to enter the corresponding dynamic positioning process hole on the support frame plate and hook onto the steel panel on the other side of the plate unit to be welded. By adjusting the position of the lateral moving hydraulic cylinder, the position of the movable hook plate relative to the fixed hook plate can be changed, thus accommodating plate units of different widths to be welded. The design of the dynamic positioning process hole allows for position adjustment.

[0016] The piston rods of the fixed-end telescopic cylinder and the moving-end telescopic cylinder are retracted respectively, and the moving hook plate and the fixed hook plate respectively position and press the steel panel of the plate unit to be welded. The plate unit to be welded has been precisely positioned and fixed on the plate unit support frame according to its own dimensions.

[0017] The combined use of the fixed-end positioning component and the moving-end positioning component enables the plate unit support jig to adapt to plate units of different sizes and shapes to be welded, thus improving the versatility of the plate unit support jig.

[0018] In summary, this utility model has at least one of the following beneficial technical effects: This invention provides a plate unit support frame. By adjusting the position of the lateral moving hydraulic cylinder, the position of the moving hook plate relative to the fixed hook plate can be changed, thereby adapting to plate units of different widths to be welded. The design of the dynamic positioning process hole allows for position adjustment.

[0019] The piston rods of the fixed-end telescopic cylinder and the moving-end telescopic cylinder are retracted respectively. The moving hook plate and the fixed hook plate respectively position and press the steel panel of the plate unit to be welded, so that the plate unit to be welded is accurately positioned and fixed on the plate unit support frame according to its own size.

[0020] The combined use of the fixed-end positioning component and the moving-end positioning component enables the plate unit support jig to adapt to plate units of different sizes and shapes to be welded, thus improving the versatility of the plate unit support jig. Attached Figure Description

[0023] The present invention will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model discloses a plate unit support frame.

[0025] Reference Figure 1 - Figure 3 Example 1: A plate unit support frame includes multiple fixed support beam assemblies 11, a support frame plate 12, and multiple plate unit lifting assemblies for assisting hoisting. The bottoms of the multiple fixed support beam assemblies 11 are detachably installed on a precast foundation, and the tops form a support surface. The bottoms of the support frame plate 12 are detachably installed on the top surface of the multiple fixed support beam assemblies 11. Fixed positioning process holes 121 and dynamic positioning process holes 122 are respectively opened on the support frame plate 12 at the positions corresponding to the multiple fixed support beam assemblies 11. The plate unit lifting assembly includes a lifting cylinder 131 and a lifting column 132. The base of the lifting cylinder 131 is detachably installed on the precast foundation, and the bottom of the lifting column 132 is detachably installed on the piston rod end of the lifting cylinder 131. When the piston rod of the lifting cylinder 131 extends or retracts, the lifting column 132 extends and retracts at the lifting auxiliary process hole 123 opened on the support frame plate 12.

[0026] Example 2: The plate unit position adaptive adjustment positioning device includes a fixed end positioning component and a moving end positioning component, which are detachably mounted on the fixed support beam component 11.

[0027] Example 3: The fixed end positioning assembly includes a fixed end telescopic cylinder 141 and a fixed hook plate 142. The cylinder body of the fixed end telescopic cylinder 141 is detachably mounted on the fixed support beam assembly 11. One end of the fixed hook plate 142 is detachably mounted on the piston rod end of the fixed end telescopic cylinder 141 and is located in the fixed positioning process hole 121. When the piston rod of the fixed end telescopic cylinder 141 retracts, the fixed hook plate 142 fixes one side of the steel panel of the plate unit 100 to be welded.

[0028] Example 4: The mobile end positioning component includes a mobile end linear guide rail, a mobile end telescopic cylinder 151, a mobile hook plate 152, and a lateral moving hydraulic cylinder 153. The mobile end linear guide rail and the lateral moving hydraulic cylinder 153 are respectively mounted on the fixed support beam assembly 11. The cylinder body of the mobile end telescopic cylinder 151 is detachably mounted on the slider of the mobile end linear guide rail. One end of the mobile hook plate 152 is detachably mounted on the piston rod end of the mobile end telescopic cylinder 151 and located in the dynamic positioning process hole 122. The piston rod of the lateral moving hydraulic cylinder 153 is connected to the cylinder body of the mobile end telescopic cylinder 151. When the piston rod of the lateral moving hydraulic cylinder 153 extends or retracts, it drives the mobile end telescopic cylinder 151 to move linearly laterally on the track of the mobile end linear guide rail. At the same time, the mobile hook plate 152 moves within the dynamic positioning process hole 122. The positional change between the mobile hook plate 152 and the fixed hook plate 142 matches the lateral dimensions of the weldable plate unit 100 of different specifications.

[0029] Example 5: The unit position adaptive adjustment positioning device further includes a plate unit edge removal mechanism. The plate unit edge removal mechanism includes a reverse movement telescopic cylinder and a reverse movement hook plate. The reverse movement telescopic cylinder is detachably installed on the fixed support beam assembly 11. One end of the reverse movement hook plate is installed at the piston rod end of the reverse movement telescopic cylinder, and the other end is located in the fixed positioning process hole 121. When the piston rod of the reverse movement telescopic cylinder is in the initial position, the reverse movement hook plate is parallel to the fixed hook plate 142. When the piston rod of the reverse movement telescopic cylinder extends, the reverse movement hook plate separates one side of the plate unit 100 to be welded from the fixed hook plate 142.

[0030] The plate unit 100 to be welded is roughly placed on the support frame plate 12 by external hoisting equipment (such as a crane), so that its position roughly corresponds to the support surface formed by the fixed support beam assembly 11.

[0031] Then, the operator activates the plate unit lifting assembly. The piston rod of the lifting cylinder 131 extends, driving the lifting column 132 to move upward until the lifting column 132 passes through the lifting auxiliary process hole 123 opened on the support frame plate 12 and presses against the bottom of the plate unit 100 to be welded.

[0032] As the lifting column 132 continues to rise, it lifts the plate unit 100 to be welded from the support surface of the support frame plate 12 by a small height, creating a small gap between the plate unit 100 to be welded and the support frame plate 12. At this time, the external hoisting equipment can release its hook.

[0033] The piston rod of the fixed-end telescopic cylinder 141 retracts, causing the fixed hook plate 142 to move inward. The fixed hook plate 142 is designed to enter the fixed positioning process hole 121 on the support frame plate 12 and ultimately hook onto the steel panel on one side of the plate unit 100 to be welded. This provides a fixed lateral positioning reference.

[0034] Based on the specific lateral dimensions (width) of the plate unit 100 to be welded, operate the lateral movement hydraulic cylinder 153.

[0035] The piston rod of the lateral moving hydraulic cylinder 153 extends or retracts, driving the moving end telescopic cylinder 151 and its cylinder body mounted thereon to move laterally in a straight line along the moving end linear guide rail.

[0036] The piston rod of the movable telescopic cylinder 151 retracts, causing the movable hook plate 152 to move inward, allowing it to enter the dynamic positioning process hole 122 at the corresponding position on the support frame plate 12 and hook onto the steel panel on the other side of the plate unit 100 to be welded. By adjusting the position of the lateral moving hydraulic cylinder 153, the position of the movable hook plate 152 relative to the fixed hook plate 142 can be changed, thereby accommodating plate units 100 of different widths. The design of the dynamic positioning process hole 122 allows for position adjustment.

[0037] The piston rods of the fixed end telescopic cylinder 141 and the moving end telescopic cylinder 151 are retracted respectively, and the moving hook plate 152 and the fixed hook plate 142 respectively position and press the steel panel of the plate unit 100 to be welded. The plate unit 100 to be welded has been precisely positioned and fixed on the plate unit support frame according to its own dimensions.

[0038] The combined use of the fixed-end positioning component and the moving-end positioning component enables the plate unit support jig to adapt to plate units 100 of different sizes and shapes to be welded, thereby improving the versatility of the plate unit support jig.

[0039] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made according to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
