Description

Technical Field

[0001] This invention relates to the field of steel structure welding, and more particularly to a welding apparatus for processing prefabricated steel structure bridge components. Background Technology

[0002] Steel structure bridges refer to bridges whose main load-bearing structure is made of steel. To speed up construction, steel structure bridges are generally built using prefabricated component assembly. This involves manufacturing prefabricated steel structure components and then transporting them directly to the construction site for assembly. When assembling prefabricated steel structure bridge components, perforated steel plates and perforated ribs are used for connection. The perforated steel plates are used to connect two steel structures with fasteners, while the perforated ribs increase the stability of the connection point. During production, the perforated steel plates and perforated ribs are pre-welded into an integrated prefabricated component to facilitate subsequent assembly.

[0003] Existing welding equipment typically requires clamping the perforated steel plate with a clamping device, finding the centerline of the perforated steel plate using a measuring and centering tool, and then aligning the perforated steel plate and the perforated rib plate. However, this process is time-consuming and inconvenient for quickly aligning the perforated rib plate and the perforated steel plate. Furthermore, after welding, the clamping and positioning devices need to be removed one by one before unloading the welded workpiece, which is not convenient for quickly unloading the welded workpiece, resulting in low work efficiency. Summary of the Invention

[0004] To overcome the shortcomings of existing welding devices, such as inconvenience in quickly aligning perforated ribs and perforated steel plates, difficulty in quickly unloading welded workpieces, and low work efficiency, this invention provides a processing and welding device for prefabricated steel structure bridge components that can easily and quickly align perforated ribs and perforated steel plates, facilitate quick unloading of welded workpieces, and improve work efficiency.

[0005] The technical solution of this invention is: a processing and welding device for precast steel structure bridge components, characterized in that: it includes a frame, the top and one side of which are open, two arc-shaped grooves on the frame, a vertical plate fixedly connected to the upper part of the inner wall of the frame, two oblique grooves on the upper part of the vertical plate, two electric push rods fixedly connected to the frame, and a slotted frame fixedly connected to the telescopic rods of the two electric push rods, and a support frame hinged to the inner wall of the frame, one end of which is fixedly connected to two force-bearing shafts, one end of which is located in one of the two arc-shaped grooves on the frame. One end of the force-bearing shaft is located in one of the two slotted frames. A placement frame is fixed to the top of the support frame. The placement frame has a placement slot, which is inclined. Several rollers are rotatably connected in the placement slot. Several ball bearings are embedded in the top of the support frame. A perforated steel plate is placed on the top of the support frame. A perforated rib is placed in the placement slot of the placement frame. A positioning and clamping mechanism is provided in the frame. The positioning and clamping mechanism is equipped with a flattening mechanism, an alignment mechanism, and a clamping mechanism.

[0006] Furthermore, the positioning and clamping mechanism includes hydraulic push rods, two of which are fixedly connected to the bottom of the inner wall of the frame. A displacement frame is fixedly connected between the telescopic rods of the two hydraulic push rods. Two multi-pass slot frames are fixedly connected to the displacement frame. Each of the two multi-pass slot frames has a limit slot. Two clamping frames are slidably connected to the vertical plate. Each clamping frame has two calibration blocks fixedly connected to it. The calibration blocks have an inclined surface. A connecting plate is fixedly connected between the two clamping frames. Two contact shafts are fixedly connected to the connecting plate. One end of each of the two contact shafts is located in the limit slot of the two multi-pass slot frames.

[0007] Furthermore, the flattening mechanism includes a rack, the rack is fixedly connected to the displacement frame, a fixing frame is fixedly connected to the upper part of the vertical plate, a gear is rotatably connected to the fixing frame, the rack meshes with the gear, and a pressing component is provided on the vertical plate.

[0008] Furthermore, the pressing assembly includes a sliding frame, which is slidably connected to the upper part of the vertical plate. A rack is fixedly connected to one side of the sliding frame, and the rack meshes with the gear. A pressing plate is slidably connected to the upper part of the sliding frame, and two contact shafts are fixedly connected to the pressing plate. One end of each contact shaft is located in one of the two inclined grooves of the vertical plate. Several ball bearings are embedded in the bottom of the pressing plate.

[0009] Furthermore, the alignment mechanism includes a rack three, which is fixedly connected to both of the two multi-pass slot frames, and two rack fours are fixedly connected to the displacement frame. The rack fours are bent, and the support frame is provided with a closing component.

[0010] Furthermore, the approaching assembly includes a threaded rod, which is rotatably connected to the inner wall of the support frame. The threaded rod has two sets of threads, which are arranged in opposite directions. Two gears are fixedly connected to the threaded rod, and the two gears are respectively located below the two racks. Two alignment frames are slidably connected to the support frame, and the two alignment frames are symmetrically arranged. Both alignment frames are threadedly connected to the threaded rod, and several ball bearings are embedded in the upper part of each alignment frame.

[0011] Furthermore, the clamping mechanism includes a guide frame, two guide frames are fixedly connected to the top of the displacement frame, the guide frames are slidably connected to the frame, a clamping frame is slidably connected between the two guide frames, a return spring is provided between the clamping frame and the two guide frames, two contact shafts are rotatably connected to the clamping frame, and two inclined blocks are fixedly connected to the inner wall of the frame, the two inclined blocks are respectively located below the two contact shafts.

[0012] Furthermore, it also includes a rubber buffer pad, which is fixed to the bottom of the inner wall of the frame and is located below the support frame.

[0013] Furthermore, it also includes wear-resistant rubber linings, and two wear-resistant rubber linings are fixedly attached to the clamping frame, with the two wear-resistant rubber linings arranged symmetrically.

[0014] The beneficial effects of this invention are as follows: 1. By using two clamping frames to drive four calibration blocks to move horizontally, the inclined surfaces on the calibration blocks are used to calibrate and position the perforated steel plate. Two alignment frames drive two sets of ball bearings to move towards the perforated rib plate. The two sets of ball bearings contact the perforated rib plate and keep the perforated rib plate and the perforated steel plate perpendicular to each other. This allows for convenient and quick centering and alignment of the perforated rib plate and the perforated steel plate, improving work efficiency.

[0015] 2. The guide frame drives the clamping frame and the return spring to move downwards. The clamping frame drives the contact shaft three to move downwards. After the perforated rib is aligned, the contact shaft three contacts the inclined block. The inclined block squeezes the contact shaft three. The contact shaft three drives the clamping frame to move horizontally towards the perforated steel plate while moving downwards. The clamping frame continues to move and contacts the perforated rib, pressing the perforated rib onto the perforated steel plate. This facilitates the clamping of the perforated rib, improves the stability of the perforated rib during welding, and enhances the welding effect.

[0016] 3. The electric push rod drives the slotted frame to move downwards. The slotted frame drives the force shaft to rotate downwards along the arc-shaped slot of the frame. The force shaft drives the support frame to rotate downwards around the hinge point with the frame. The support frame drives the placement frame, rollers, ball bearings, threaded rod, gear, alignment frame, and ball bearings to rotate downwards. After welding, the positioning and clamping mechanisms disengage from the perforated steel plate and perforated rib. Under the action of gravity, the welded perforated steel plate and perforated rib will fall downwards to the bottom of the inner wall of the frame, which facilitates the quick unloading of the welded workpiece and further improves work efficiency.

There are two force-bearing shafts 6, which are symmetrically arranged. One end of each force-bearing shaft 6 is located in one of the two arc-shaped grooves on the frame 1, and the other end is located in one of the two straight slot frames 4. The electric push rod 3 drives the force-bearing shafts 6 to rotate through the straight slot frames 4, thereby driving the support frame 5 to rotate. A placement frame 7 is fixed to the top of the support frame 5. The placement frame 7 has a placement groove, which is inclined. Several components are rotatably connected in the placement groove of the placement frame 7. A plurality of rollers 8 are evenly spaced.

The positioning and clamping mechanism is provided with a clamping mechanism for clamping the perforated rib 11.

[0033] The positioning and clamping mechanism includes hydraulic push rods 121. Two hydraulic push rods 121 are bolted to the bottom of the inner wall of the frame 1. The two hydraulic push rods 121 are symmetrically arranged. A displacement frame 122 is fixed between the telescopic rods of the two hydraulic push rods 121. Two multi-pass slot frames 123 are fixed to the displacement frame 122. The two multi-pass slot frames 123 are symmetrically arranged. Each of the two multi-pass slot frames 123 has a limit groove. Two clamping frames 124 are slidably connected to the vertical plate 2. The hydraulic push rods 121 drive the multi-pass slot frames 123 to move through the displacement frame 122. Two calibration blocks 125 are fixedly attached to each of the clamping frames 124. The two calibration blocks 125 on the same clamping frame 124 are symmetrically arranged. Each calibration block 125 has an inclined surface. A connecting plate 126 is fixedly connected between the two clamping frames 124. Two contact shafts 127 are fixedly attached to the connecting plate 126. One end of each contact shaft 127 is located in the limiting groove of each of the two multi-pass slot frames 123. The multi-pass slot frame 123 drives the connecting plate 126 to move through the contact shafts 127, and then drives the calibration blocks 125 to move through the clamping frames 124.

[0034] The flattening mechanism includes a rack 131, which is welded onto the displacement frame 122. A fixing frame 132 is fixedly connected to the upper part of the vertical plate 2. A gear 133 is rotatably connected to the fixing frame 132. The rack 131 meshes with the gear 133. A pressing component is provided on the vertical plate 2.

[0035] The pressing assembly includes a sliding frame 134, which is slidably connected to the upper part of the vertical plate 2. A rack 135 is fixedly connected to one side of the sliding frame 134. The rack 135 meshes with a gear 133. The rack 131 drives the rack 135 to move through the gear 133, thereby driving the sliding frame 134 to move. A pressing plate 136 is slidably connected to the upper part of the sliding frame 134. The pressing plate 136 is located on the belt. Above the perforated steel plate 10, two contact shafts 137 are fixedly connected to the lower pressure plate 136. The two contact shafts 137 are symmetrically arranged, and one end of each contact shaft 137 is located in one of the two inclined grooves of the vertical plate 2. Several ball bearings 138 are embedded in the bottom of the lower pressure plate 136 and are evenly spaced. The contact shafts 137 move the lower pressure plate 136, which in turn moves the ball bearings 138.

[0036] The alignment mechanism includes a rack 3 141, and the rack 3 141 is fixedly connected to both of the two multi-pass slot frames 123. The multi-pass slot frames 123 are used to drive the rack 3 141 to move up and down. Two racks 4 142 are fixedly connected to the displacement frame 122. The displacement frame 122 is used to drive the racks 4 142 to move up and down. The racks 4 142 are bent. The two racks 3 141 and the two racks 4 142 are symmetrically arranged. The support frame 5 is provided with a closing component.

[0037] The approaching assembly includes a threaded rod 143, which is connected to the inner wall of the support frame 5 via bearings. The threaded rod 143 has two sets of threads, which are arranged in opposite directions. Two gears 144 are connected to the threaded rod 143 via splines. The two gears 144 are located below the two racks 141. Two alignment frames 145 are slidably connected to the support frame 5. The two alignment frames 145 are located on both sides of the placement frame 7 and are symmetrically arranged. Both alignment frames 145 are threadedly connected to the threaded rod 143. Several balls 146 are embedded in the upper part of each alignment frame 145. The balls 146 on the same alignment frame 145 are evenly spaced. The racks 141 drive the threaded rod 143 to rotate via the gears 144, thereby moving the two alignment frames 145.

[0038] The clamping mechanism includes a guide frame 151. Two guide frames 151 are bolted to the top of the displacement frame 122. The two guide frames 151 are symmetrically arranged. The guide frames 151 are slidably connected to the frame 1. A clamping frame 152 is slidably connected between the two guide frames 151. A return spring 153 is provided between the clamping frame 152 and the two guide frames 151. Two contact shafts 154 are rotatably connected to the clamping frame 152. The two contact shafts 154 are symmetrically arranged. The displacement frame 122 drives the clamping frame 152 to move through the guide frames 151, thereby driving the contact shafts 154 to move. Two inclined blocks 155 are fixed to the inner wall of the frame 1. The two inclined blocks 155 are symmetrically arranged and located below the two contact shafts 154. The inclined blocks 155 drive the clamping frame 152 to move by pressing the contact shafts 154.

[0039] Initially, the electric push rod 3 supports the force-bearing shaft 6 through the slotted frame 4, thereby keeping the support frame 5, placement frame 7, roller 8, and ball bearing 9 horizontal and stationary. The operator inserts the perforated steel plate 10 between the two clamping frames 124 and the vertical plate 2, so that the bottom of the perforated steel plate 10 contacts the top of the support frame 5 and the ball bearing 9, and contacts one side of the vertical plate 2. After the perforated steel plate 10 is placed, the operator places the perforated rib plate 11 into the placement slot of the placement frame 7, so that the inclined surface of the perforated rib plate 11 slides down along the roller 8. When the bottom of the perforated rib plate 11 contacts the top of the support frame 5, and one side of the perforated rib plate 11 contacts the ball bearing 9, the perforated rib plate 10 slides down along the slotted frame 7. After the steel plate 10 makes contact, the operator adjusts the telescopic rod of the hydraulic push rod 121 to retract downwards. The downward movement of the telescopic rod of the hydraulic push rod 121 causes the displacement frame 122 to move downwards. The downward movement of the displacement frame 122 causes the multi-pass slot frame 123 and rack 131 to move downwards. The downward movement of rack 131 causes gear 133 to rotate. The rotation of gear 133 causes rack 135 to move downwards. The downward movement of rack 135 causes sliding frame 134 to move downwards. The downward movement of sliding frame 134 causes lower pressure plate 136 to move downwards. The downward movement of lower pressure plate 136 causes contact shaft 137 and ball bearing 138 to move downwards. When the contact shaft 137 moves along the inclined groove of the vertical plate 2, it drives the lower pressure plate 136 and the ball bearing 138 to move horizontally above the perforated steel plate 10 while moving downward. The lower pressure plate 136 continues to move downward, pressing the perforated steel plate 10 flat to a vertical state. Through the above operations, the perforated steel plate 10 can be kept perpendicular to the support frame 5, which facilitates the subsequent tight fit between the perforated steel plate 10 and the perforated rib plate 11. The rack 131 continues to move downward and disengages from the gear 133. The multi-pass slot frame 123 continues to move downward and presses the contact shaft 127. The contact shaft 127 will drive the connecting plate 126 towards... Moving away from the vertical plate 2, the connecting plate 126 moves away from the vertical plate 2, causing the two clamping frames 124 to move horizontally. The horizontal movement of the two clamping frames 124 causes the four calibration blocks 125 to move horizontally. The inclined surface on the calibration block 125 will calibrate and position the perforated steel plate 10. The first ball 9 and the second ball 138 are used to reduce the wear between the perforated steel plate 10 and the support frame 5 and the lower pressure plate 136, so that the perforated steel plate 10 can move more smoothly. The clamping frame 124 continues to move horizontally and presses the perforated steel plate 10 tightly onto the vertical plate 2. Through the above operations, the perforated steel plate 10 can be positioned and clamped.

[0040] The downward movement of the displacement frame 122 causes the rack four 142 and guide frame 151 to move downwards. The downward movement of the multi-pass slot frame 123 causes the rack three 141 to move downwards. After the perforated steel plate 10 is positioned and clamped, the rack three 141 meshes with the gear two 144, causing the gear two 144 to rotate. The rotation of the gear two 144 causes the threaded rod 143 to rotate. Under the action of the two sets of opposite threads on the threaded rod 143, the two alignment frames 145 move towards each other. The movement of the two alignment frames 145 towards each other causes the two sets of ball bearings three 146 to move towards the perforated rib plate 11. The two sets of ball bearings three 146 contact the perforated rib plate 11 and keep the perforated rib plate 11 perpendicular to the perforated steel plate 10. Through the above operations, This facilitates the alignment of the perforated rib 11. The rack 141 continues to move downwards, disengaging from the gear 144. The guide frame 151 moves downwards, causing the clamping frame 152 and the return spring 153 to move downwards. The clamping frame 152 moves downwards, causing the contact shaft 154 to move downwards. After the perforated rib 11 is aligned, the contact shaft 154 contacts the wedge block 155, which presses against the contact shaft 154. The contact shaft 154 causes the clamping frame 152 to move horizontally towards the perforated steel plate 10 while moving downwards. The return spring 153 is compressed. The clamping frame 152 continues to move and contacts the perforated rib 11, pressing the perforated rib 11 onto the perforated steel plate 10. Through the above operations, the perforated rib 11 can be easily aligned. 1. Clamping is performed to improve the stability of the perforated rib plate 11 during welding and enhance the welding effect. After clamping the perforated rib plate 11, the operator pauses the hydraulic push rod 121 and adjusts the extension rod of the electric push rod 3 to extend downward. The extension rod of the electric push rod 3 moves downward, causing the slotted frame 4 to move downward. The downward movement of the slotted frame 4 causes the force shaft 6 to rotate downward along the arc-shaped groove of the frame 1. The downward rotation of the force shaft 6 causes the support frame 5 to rotate downward around the hinge point with the frame 1. The downward rotation of the support frame 5 causes the placement frame 7, roller 8, ball bearing 9, threaded rod 143, gear 144, alignment frame 145, and ball bearing 146 to rotate downward. Through the above operations, the parts of the perforated steel plate 10 and the perforated rib plate 11 that need to be welded can be exposed, facilitating the work. The workers performed welding operations. The rack 142 was bent to allow the gear 144 to pass smoothly without obstruction during its downward rotation. Then, the workers used existing welding equipment to weld the contact area between the perforated steel plate 10 and the perforated rib plate 11. After welding, the workers adjusted the extension rod of the hydraulic push rod 121 to extend upwards. The upward movement of the extension rod of the hydraulic push rod 121 moved the displacement frame 122 upwards. The upward movement of the displacement frame 122 moved the rack 142, the multi-pass slot frame 123, the rack 131, and the guide frame 151 upwards. The upward movement of the rack 142 engaged with the gear 144, causing the gear 144 to rotate in the opposite direction. The reverse rotation of the gear 144 caused the threaded rod 143 to rotate in the opposite direction.The reverse rotation of the threaded rod 143 causes the two alignment brackets 145 to move away from each other. This movement of the two alignment brackets 145 causes the two sets of ball bearings 146 to move away from each other. The rack 142 continues to move upwards and disengages from the gear 144. The guide bracket 151 moves upwards, causing the clamping bracket 152, the return spring 153, and the contact shaft 154 to move upwards. The wedge block 155 no longer presses against the contact shaft 154. The return spring 153 rebounds and causes the clamping bracket 152 to move away from the perforated steel plate 10. The clamping bracket 152 releases the perforated rib 11. The multi-pass slotted frame 123 moves upwards, causing the rack 146 to move away from the perforated steel plate 10. 141 moves upward. After clamping frame 152 releases the perforated rib plate 11, multi-pass slot frame 123 applies reverse pressure to contact shaft 127. Contact shaft 127 drives connecting plate 126 to move closer to vertical plate 2. The movement of connecting plate 126 towards vertical plate 2 drives two clamping frames 124 to move in the opposite direction. The reverse movement of two clamping frames 124 drives four calibration blocks 125 to move in the opposite direction. The clamping frames 124 and calibration blocks 125 disengage from the perforated steel plate 10. Under the action of gravity, the welded perforated steel plate 10 and perforated rib plate 11 fall downward to the bottom of the inner wall of frame 1. Through the above operation, it is convenient to quickly weld the... The workpiece is unloaded to further improve work efficiency. Rack 131 continues to move upward and meshes with gear 133, causing gear 133 to rotate in the opposite direction. The reverse rotation of gear 133 causes rack 2 135 to move upward. The upward movement of rack 2 135 causes sliding frame 134 to move upward. The upward movement of sliding frame 134 causes lower pressure plate 136 to move upward. The upward movement of lower pressure plate 136 causes contact shaft 2 137 and ball bearing 2 138 to move upward. Contact shaft 2 137 will move in the opposite direction along the inclined groove of vertical plate 2, and cause lower pressure plate 136 and ball bearing 2 138 to move towards gear 133 while moving upward. After reset (step 36), the operator stops the hydraulic push rod 121, removes the welded perforated steel plate 10 and perforated rib plate 11, and then adjusts the telescopic rod of the electric push rod 3 to retract upwards. The upward movement of the telescopic rod of the electric push rod 3 causes the slotted frame 4 to move upwards. The upward movement of the slotted frame 4 causes the force-bearing shaft 6 to rotate upwards along the arc-shaped groove of the frame 1. The upward rotation of the force-bearing shaft 6 causes the support frame 5 to rotate upwards around the hinge point with the frame 1. The upward rotation of the support frame 5 causes the placement frame 7, roller 8, ball bearing 9, threaded rod 143, gear 144, alignment frame 145, and ball bearing 146 to rotate upwards. Finally, the operator stops the electric push rod 3 to facilitate the next operation.

[0041] Example 2: Based on Example 1, such as Figures 1-2 and Figures 8-10As shown, it also includes a rubber buffer pad 16, which is fixed to the bottom of the inner wall of the frame 1. The rubber buffer pad 16 is located below the support frame 5 and is used to protect the perforated steel plate 10 and the perforated rib plate 11 from falling downwards.

[0042] It also includes wear-resistant rubber linings 17, and two wear-resistant rubber linings 17 are fixedly attached to the clamping frame 152. The two wear-resistant rubber linings 17 are arranged symmetrically, and the wear-resistant rubber linings 17 are used to make the clamping frame 152 clamp the perforated rib 11 more securely.

[0043] The rubber buffer pad 16 can provide cushioning when the welded perforated steel plate 10 and perforated rib 11 fall downwards for discharge, increasing the safety of the perforated steel plate 10 and perforated rib 11 during discharge.

[0044] The wear-resistant rubber liner 17 can increase the friction between the clamping frame 152 and the perforated rib 11, and improve the stability of the clamping frame 152 when clamping the perforated rib 11.

The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
