Description

Technical Field

[0001] The invention relates to the technical field of corrugated steel web welding devices, in particular to a construction welding device for a corrugated steel web composite beam bridge. Background Art

[0002] The composite beam bridge with corrugated steel web is a type of bridge structure that combines concrete top and bottom plates with corrugated steel webs. This type of bridge has been widely used in modern bridge engineering due to its advantages such as efficient use of materials, reduced deadweight, and simplified construction process.

[0003] The corrugated steel web composite beam bridge consists of a concrete top and bottom slabs and a corrugated steel web. The corrugated steel web connects the upper and lower concrete slabs to provide bending stiffness and support. The corrugated steel web increases the section moment of inertia through a special corrugated shape, which can improve shear resistance and overall stability.

[0004] The corrugated steel web is relatively long and is generally welded together from multiple shorter corrugated plates. Before welding, the corrugated plates need to be positioned to improve welding accuracy and ensure welding quality.

[0005] A positioning device in the prior art, such as a corrugated steel web welding fixing device disclosed in a patent with authorization announcement number CN219443966U, comprises a base, two sliding grooves are provided on the top of the base, and the inner walls of the two sliding grooves are connected to a bidirectional screw rod through bearings, a servo motor is provided on an outer wall of one side of the base, the output shaft of the servo motor is connected to the bidirectional screw rod, a slider is sleeved on the outer wall of the bidirectional screw rod, two moving platforms are provided on the top outer wall of the slider, limiting grooves are provided on the top of the two moving platforms, hydraulic cylinders are provided on both sides of the top outer wall of the moving platform, the piston rod of the hydraulic cylinder is connected to a top plate, an extrusion mechanism is provided at the bottom of the top plate, and a gantry is provided in the middle of the top outer wall of the base.

[0006] The device positions the corrugated plates by placing them in the limit slots on the moving tables, driving the two moving tables closer to each other, putting the two corrugated plates together, and then moving the top plate down to press on the corrugated plates. However, the device can only position corrugated plates of the same model, and its application range is relatively narrow. In actual production, the corrugated steel web is usually welded from more than two corrugated plates, and the device can only position two corrugated plates. When the required corrugated steel web is long and needs to be welded from a large number of corrugated plates, it is difficult to position multiple corrugated plates at one time using the positioning device. Summary of the invention

[0007] The present invention provides a construction welding device for a corrugated steel web composite beam bridge, so as to solve the technical problems in the prior art that when welding corrugated steel webs, the positioning device cannot position multiple different types of corrugated plates, cannot position a large number of corrugated plates at the same time, and has a narrow application range.

[0008] In order to solve the above problems, the present invention provides a construction welding device for a corrugated steel web composite beam bridge, which adopts the following technical solution: A construction welding device for a corrugated steel web composite beam bridge comprises a base frame, on which a support beam, a transverse clamping mechanism, a moving drive mechanism and a centering pressing mechanism are arranged, a plurality of support beams are provided, the plurality of support beams extend in a front-to-rear direction and are arranged at intervals in a left-to-right direction, and each support beam is slidably mounted on the base frame in a left-to-right direction; Each support beam is provided with a set of transverse clamping mechanisms on both sides, and the transverse clamping mechanisms are slidably installed on the bottom frame. The transverse clamping mechanisms include two support blocks arranged symmetrically on the left and right sides, and a clamping arm is provided at one end of the support block facing away from the other support block. The clamping arm includes a clamping block, and a gap is provided between the clamping block and the support block in the left and right directions. The two support blocks can be synchronously approached to each other to drive the clamping blocks to be pressed against the two straight edges of the corrugated plate; The mobile driving mechanism can drive each lateral clamping mechanism to approach each other, so as to drive the clamping block to be pressed against the support beam on the corresponding side. The clamping block is pushed by the support beam and can rotate to below the top surface of the support block and move toward the corresponding support block, so that the end of the corrugated plate moves above the support beam. Each support beam is provided with a set of centering and clamping mechanisms, which include two clamping components symmetrically distributed front and back. The two clamping components can approach each other synchronously to push the two corrugated plates on the support beam to be centered. The clamping components can also press the corrugated plates onto the support beam after the corrugated plates are centered.

[0009] With the above technical solution, a support beam, a transverse clamping mechanism and a centering clamping mechanism are provided on the chassis. The support beam and the transverse clamping mechanism can slide in the left and right directions. The centering clamping mechanism is installed on the support beam. When positioning the corrugated plate to be welded, the corrugated plate can be placed on the transverse clamping mechanism first. The transverse clamping mechanism clamps the corrugated plate and aligns the corrugated plate in the front-back direction. After that, each group of transverse clamping mechanisms approaches each other under the drive of the mobile driving mechanism. Each corrugated plate is driven by the mobile driving mechanism to move closer to each other, and each support beam is finally clamped between two adjacent groups of transverse clamping mechanisms. When the clamping block contacts the support beam, it can rotate to the bottom of the corrugated plate and be pushed by the support beam to move toward the corresponding support block. In this way, the end of the corrugated plate can be placed on the support beam, so that multiple corrugated plates are spliced ​​together, and the splicing positions are all located above the support beam, which is convenient for subsequent welding.

[0010] The centering and clamping mechanism can align all corrugated plates in the left and right directions, and press the aligned corrugated plates onto the support beams, thereby fixing the corrugated plates and making the welding process more stable. The equipment can clamp, splice and position a variety of different types of corrugated plates, has a wider range of applications, and can splice and position multiple corrugated plates at the same time, with higher positioning efficiency.

[0011] Furthermore, the clamping arm also includes a slider, which is elastically slidably installed on the support block left and right, and is mutually stopped from rotating with the support block, one end of the slider extends to the outside of the support block, the bottom end of the clamping block is rotatably installed on the end of the slider extending to the outside of the support block, and a torsion spring is connected to the slider, the bottom end of the clamping block is provided with a slot with an opening facing away from the support block, and the left and right side walls of the support beam are provided with driving rods corresponding to the slots, and in the process of the clamping arm and the support beam approaching each other, the driving rod is inserted into the slot and spirally transmitted with the clamping block to drive the clamping block to rotate below the top surface of the support block, and the support beam pushes the clamping block rotated below the top surface of the support block and the slider to move toward the support block, so that the part of the corrugated plate extending to the outside of the support block moves above the support beam.

[0012] By adopting the above technical solution, when the horizontal clamping mechanism approaches the support beam, the driving rod is inserted into the slot, driving the clamping block to rotate downward. The clamping block is no longer blocked at the end of the corrugated plate, which facilitates the splicing of the corrugated plate. The slider can slide left and right, so that after the clamping block rotates downward, the clamping arm can be pushed by the support beam to move toward the support block, so that the end of the corrugated plate can move above the support beam. The structure is simple and ingenious.

[0013] Furthermore, the transverse clamping mechanism also includes a bracket and a double-head clamping cylinder. The bracket is installed on the base frame for left and right guiding sliding. The two support blocks are installed on the bracket for left and right sliding. The two output ends of the double-head clamping cylinder are respectively connected to the two support blocks to drive the two support blocks to move closer or farther away from each other synchronously.

[0014] By adopting the above technical solution, a double-head clamping cylinder is used to drive the two support blocks to move closer to or away from each other, which has a simple structure and is more convenient for equipment assembly.

[0015] Furthermore, guide slopes are provided on both left and right sides of the top of the support beam, and the two guide slopes on the support beam are away from each other from top to bottom.

[0016] The above technical solution facilitates the movement of the end of the corrugated plate to above the support beam.

[0017] Furthermore, the clamping assembly includes a pushing member 1 and a pushing member 2 which are arranged at intervals in the front and rear directions. Both the pushing member 1 and the pushing member 2 are installed on the support beam in a forward and backward guided sliding manner. The pushing member 1 is located on one side close to the center of the support beam. An elastic member 1 which can be extended and retracted forward and backward is connected between the pushing member 1 and the pushing member 2. A pressure rod is provided on the top of the pushing member 1. The middle part of the pressure rod is rotatably installed on the pushing member 1 along a rotation axis extending left and right, and a torsion spring 2 is connected between the pressure rod and the pushing member 1. A pushing block is provided on the top of the pushing member 2. A pushing inclined surface which is inclined from top to bottom toward the pushing member 1 is provided on the side of the push block facing the pushing member 1.

[0018] By adopting the above technical solution, an elastic member 1 is connected between the pushing member 1 and the pushing member 2. When the two sets of clamping components approach each other, the two pushing members 1 first push the corrugated plate to center the corrugated plate. After the corrugated plate is clamped between the two pushing members 1, the resistance encountered by the pushing member 1 increases, the elastic member is compressed at first, and the pushing member 2 begins to approach the pushing member 1. During this process, the push block moves toward the pressure rod and lifts up one end of the pressure rod toward the pushing member 1 through the pushing inclined surface, and the other end of the pressure rod moves downward to press the corrugated plate against the support beam, thereby fixing the corrugated plate. In this way, the position of the corrugated plate is more stable during the subsequent welding process and no offset will occur.

[0019] Furthermore, the pushing member 1 includes two pushing blocks 1 that are symmetrical and spaced apart, the two pushing blocks 1 are relatively fixed in the front-to-back direction, a gap is provided between the pushing block 1 and the top surface of the support beam, and the pushing member 2 includes two pushing blocks 2 that are symmetrical and spaced apart, the two pushing blocks 2 are relatively fixed in the front-to-back direction, a gap is provided between the pushing block 2 and the top surface of the support beam, the gap area between the pushing block 1 and the top surface of the support beam is connected with the gap area between the pushing block 2 and the top surface of the support beam to form a receiving groove for receiving the arc-starting plate, and a baffle is provided at the rear end of the pushing block 2, and when the two clamping assemblies are close to each other, the arc-starting plates in the two clamping assemblies are pushed close to each other by the baffle.

[0020] By adopting the above technical scheme, before starting the centering and clamping mechanism, the arc-starting plate is first inserted into the accommodating groove, and then in the process of the clamping components approaching each other, the arc-starting plate is driven to move toward the corrugated plate, and the arc-starting plate is pressed on the corrugated plate while the corrugated plate is centered and clamped and fixed. The arc-starting plate is fixed to the corrugated plate by the mechanical structure. Before welding the corrugated plate, it is not necessary to fix the arc-starting plate on the corrugated plate by welding, which can save welding materials. When the arc-starting plate needs to be cut after the welding of the corrugated plate is completed, since the arc-starting plate and the corrugated plate are only adhered to each other at the arc-starting position, cutting is more convenient, the cutting efficiency is higher, and the wear on the cutting knife is less.

[0021] Furthermore, the centering and clamping mechanism also includes a double-headed centering cylinder, which is installed on the support beam, and the two output ends of the double-headed centering cylinder are respectively connected to the two push members in the two groups of clamping assemblies.

[0022] By adopting the above technical solution, a double-head centering cylinder is used to drive two groups of clamping components to move toward or away from each other synchronously, which has a simple structure and is easy to assemble.

[0023] Furthermore, a movable frame is installed on the base frame and spans the base frame in the front-to-back direction. The movable frame is installed on the base frame so as to be movable left and right. A welding machine that can move forward and backward is arranged on the movable frame.

[0024] By adopting the above technical solution, the welding machine is installed on a movable frame, so that the welding machine can move back and forth in the left and right directions to weld various splicing positions of multiple corrugated plates.

[0025] The beneficial effects of the construction welding device for a corrugated steel web composite beam bridge provided by the present invention are as follows: by arranging a transverse clamping mechanism and a centering clamping mechanism, various different types of corrugated plates can be clamped, assembled and fixed, and the scope of application is wider. By arranging a support beam that can move left and right, and making the transverse clamping mechanism movably installed on the base frame left and right, multiple corrugated plates can be clamped and positioned at the same time, and after all the corrugated plates are positioned, they are welded at each splicing position, which can improve the processing efficiency.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0029] The following is one embodiment of a construction welding device for a corrugated steel web composite beam bridge provided by the present invention: like Figure 1-Figure 7 As shown, a construction welding device for a corrugated steel web composite beam bridge includes a base frame 1, a support beam 5, a transverse clamping mechanism, a mobile driving mechanism, a centering and clamping mechanism, a movable frame 3 and a welding machine.

[0030] like Figure 1 , Figure 2 As shown, the base frame 1 is arranged horizontally on the ground, and includes two horizontal beams 101 extending left and right and arranged at intervals in front and back. A driving screw 2 extending left and right is rotatably installed on the front and rear sides of the base frame 1, and two motors are also provided on the base frame 1 for driving the two driving screws 2 to rotate, respectively, and the motors are not shown in the figure.

[0031] There are multiple support beams 5, and the multiple support beams 5 are arranged on the bottom frame 1 at intervals along the left-right direction. Each support beam 5 extends along the front-back direction, and each support beam 5 is guided and slidably assembled on the bottom frame 1 along the left-right direction. The specific assembly method is: the front and rear ends of the support beam 5 are connected with the first U-shaped fasteners 6, and the two first U-shaped fasteners 6 at the front and rear ends of the support beam 5 are respectively covered on the two cross beams 101. The two first U-shaped fasteners 6 prevent the support beam 5 from being separated from the bottom frame 1, and enable the support beam 5 to slide back and forth along the left-right direction on the bottom frame 1.

[0032] Chamfers are provided on both sides of the top of the support beam 5 to form guide slopes. The two guide slopes move away from each other from top to bottom. The guide slopes are used to guide the end of the corrugated plate 4 to move above the support beam 5. The guide slopes are not shown in the figure.

[0033] like Figure 3 , Figure 4 As shown, two driving rods 14 extending left and right and arranged with intervals front and back are connected to the left and right beam walls of the support beam 5. The driving rods 14 on the left and right sides of the support beam 5 are arranged symmetrically, and the driving rods 14 are provided with threads on the outside.

[0034] There are multiple groups of transverse clamping mechanisms, and each support beam 5 is provided with a group of transverse clamping mechanisms on both sides. Figure 3 , Figure 4 As shown, the transverse clamping mechanism includes a bracket 7, a double-head clamping cylinder 8, a support block 9 and a clamping arm.

[0035] The bracket 7 includes a longitudinal rod 701 and two transverse rods 702. The longitudinal rod 701 extends in the front-to-back direction. The two transverse rods 702 extend in the left-to-right direction. The two transverse rods 702 are connected to the middle of the longitudinal rod 701 and are respectively arranged on the left and right sides of the longitudinal rod 701. The longitudinal rod 701 is guided and slidably installed on the base frame 1 along the left-to-right direction. The specific sliding installation method is: the front and rear ends of the longitudinal rod 701 are connected with the second U-shaped fasteners 21, and the two second U-shaped fasteners 21 at the front and rear ends of the longitudinal rod 701 are respectively covered on the two cross beams 101.

[0036] The double-headed clamping cylinder 8 is installed above the two cross bars 702 and is aligned with the longitudinal bar 701. The double-headed clamping cylinder 8 has two output ends that can synchronously approach or move away from each other in the left and right directions.

[0037] There are two support blocks 9, which are slidably mounted on the two cross beams 101 along the left and right directions respectively. The two support blocks 9 are symmetrically arranged on the left and right sides and are respectively connected to the two output ends of the double-head clamping cylinder 8. The double-head clamping cylinder 8 can drive the two support blocks 9 to move synchronously closer to each other or move synchronously away from each other.

[0038] Each support block 9 is provided with two guide holes spaced apart from each other at one end thereof, the guide holes extending left and right and having a square cross section.

[0039] like Figure 2 As shown, four clamping arms are provided, and two clamping arms spaced apart from each other are provided on the side of each support block 9 facing away from the other support block 9 , and the clamping arm includes a slider 10 and a clamping block 11 .

[0040] The slider 10 extends in the left-right direction and has a square cross section. The slider 10 is inserted into the guide hole in a sliding manner in the left-right direction. Figure 7 As shown, an elastic member 23 capable of extending and retracting in the left and right directions is connected between the bottom surface of the guide hole and the slider 10. The elastic member 23 is a compression spring. The elastic member 23 applies an elastic force to the slider 10 that is directed away from the support block 9, so that half of the slider 10 extends to the outside of the support block 9. The end surface of the slider 10 that extends to the outside of the support block 9 is provided with a shaft section 24 extending left and right.

[0041] The support block 9 is also provided with a stopping step 901 for preventing the slider 10 from sliding toward the outside of the guide hole. The elastic member 23 presses the slider 10 against the stopping step 901 in the direction away from the support block 9. The stopping step 901 prevents the slider 10 from sliding, so that the slider 10 can only move toward the inside of the guide hole but cannot move toward the outside of the guide hole.

[0042] like Figure 3 As shown, the clamping block 11 includes a cylindrical section 112 extending left and right of the axis and a straight rod section 111 connected to the cylindrical section 112 and extending radially of the cylindrical section 112. The cylindrical section 112 is longer than the shaft section 24 at the end of the slider 10. The half side of the cylindrical section 112 close to the support block 9 is rotatably mounted on the shaft section 24 and a torsion spring 1 is connected between the shaft section 24. The torsion spring 1 keeps the straight rod section 111 in a vertical state. When the straight rod section 111 is in a vertical state, the top end of the straight rod section 111 is higher than the top surface of the support block 9.

[0043] The other half of the cylindrical section 112 is provided with a slot with an opening facing away from the support block 9. The two slots in the two clamping arms on the same support block 9 respectively correspond to the two driving rods 14 located on the same beam wall in the above-mentioned support beam 5, and the cylindrical section 112 can cooperate with the driving rod 14 through the slot through spiral transmission, that is, the driving rod 14 can drive the cylindrical section 112 to rotate during the process of being inserted into the slot, and the cylindrical section 112 can drive the straight rod section 111 to rotate below the top surface of the support block 9.

[0044] A groove communicating with the guide hole is provided on the supporting block 9 beside the guide hole, and the straight rod section 111 rotated below the top surface of the supporting block 9 can be retracted into the groove when pushed by the supporting block 9 .

[0045] When the slider 10 is stopped by the stopping step 901, the spacing between the side wall of the clamping block 11 facing the support block 9 and the support block 9 is equal to half of the width of the support beam 5 in the left-right direction, so that when the two corrugated plates 4 are placed on the support beam 5, the gap formed by the two corrugated plates 4 is located in the middle of the support beam 5.

[0046] When the transverse clamping mechanism is in use, the corrugated plate 4 is placed on two support blocks 9, and the two ends of the corrugated plate 4 are respectively placed on the two support blocks 9, and then the double-head clamping cylinder 8 is started to drive the two support blocks 9 to approach each other, and the straight rod sections 111 in the clamping arms on the left and right sides are respectively pressed on the straight edges on the left and right sides of the corrugated plate 4, clamping the corrugated plate 4 and aligning the corrugated plate 4 in the front and rear directions.

[0047] The mobile driving mechanism includes a winding motor and a winding drum connected to the winding motor, both of which are arranged on the right side of the chassis 1. A pull rope is wound on the winding drum, which is connected to the longitudinal rod 701 in the leftmost transverse clamping mechanism. The winding motor controls the winding drum to rotate and drives the pull rope to be wound on the winding drum, thereby pulling the leftmost transverse clamping mechanism and the corrugated plate 4 clamped therein to move rightward, pushing each transverse clamping mechanism and the support beam 5 to move rightward to each other, thereby realizing the splicing of multiple corrugated plates 4. The mobile driving mechanism can be independently arranged on the outside of the chassis 1, and its structure is not shown in the figure.

[0048] like Figure 3 , Figure 4 As shown, there are multiple groups of centering and clamping mechanisms, and each support beam 5 is equipped with a group of centering and clamping mechanisms, which include a double-headed centering cylinder 12 and a clamping assembly.

[0049] The double-head centering cylinder 12 is installed at the bottom of the support beam 5 and is aligned with the support beam 5 in the front-to-back direction. The double-head centering cylinder 12 has two output ends that can synchronously approach or move away from each other in the front-to-back direction. Two first connecting plates 13 are respectively connected to the two output ends of the double-head centering cylinder 12. The first connecting plates 13 are in a U-shape with the opening facing upward. The first connecting plates 13 are buckled from top to bottom on the outside of the support beam 5 through the U-shaped notch.

[0050] There are two groups of clamping assemblies, which are symmetrically installed on the support beam 5 front and back. The clamping assemblies include a first pushing member, a second pushing member, an elastic member, a pressure rod 19 and a push block 16.

[0051] like Figure 5 , Figure 6 As shown, the first pushing member and the second pushing member are arranged with a front-to-back spacing, and the first pushing member is located on a side close to the center of the support beam 5.

[0052] The push member 1 includes two push blocks 18 that are symmetrical and spaced apart. Both push blocks 18 are slidably mounted on the support beam 5 and are respectively located on the left and right sides of the support beam 5. The push block 18 includes a top plate 181, a bottom plate 182, and a vertical connecting plate 183. The top plate 181 is located above the bottom plate 182 and is parallel to the bottom plate 182. The vertical connecting plate 183 is connected between the top plate 181 and the end of the bottom plate 182 that is away from the support beam 5.

[0053] The push block 18 is installed on the support beam 5 by guiding and sliding forward and backward through the bottom plate 182. The specific connection method is: the end of the bottom plate 182 facing away from the vertical connecting plate 183 is connected with a T-shaped slider 1, and the left and right side walls of the support beam 5 are both provided with a strip-shaped slide groove extending forward and backward with a T-shaped cross section. The T-shaped slide groove is inserted in the strip-shaped slide groove and can slide forward and backward along the strip-shaped slide groove. When the bottom plate 182 is guided and slidably installed on the support beam 5, the top plate 181 is located above the support beam 5 and a gap is provided between the top surface of the support beam 5.

[0054] The push member 2 includes two push blocks 15 that are symmetrical and spaced apart. Both push blocks 15 are slidably mounted on the support beam 5 and are respectively located on the left and right sides of the support beam 5. The push block 15 includes a top plate 151, a bottom plate 152, a vertical connecting plate 153 and a baffle 154. The top plate 151 is located above the bottom plate 152 and is parallel to the bottom plate 152. The vertical connecting plate 153 is connected between the top plate 151 and the end of the bottom plate 152 that is away from the support beam 5. The baffle 154 is connected between the top plate 151 and the end of the bottom plate 152 that is away from the support beam 5.

[0055] The second push block 15 is installed on the support beam 5 by means of the second bottom plate 152 to guide and slide forward and backward. The specific connection method is as follows: a T-shaped slider 2 is provided at one end of the second bottom plate 152 facing away from the second vertical connecting plate 153, and the T-shaped slider 2 is inserted into the strip-shaped slide groove on the corresponding side. The second top plate 151 is located above the support beam 5 and is spaced apart from the top surface of the support beam 5. The two second bottom plates 152 in the push piece 2 are both connected to the first connecting plate 13.

[0056] like Figure 3 , Figure 4 As shown, the two bottom plates 182 in the push member 1 are connected to the second connecting plate 22. The second connecting plate 22 has the same structure as the first connecting plate 13 and is buckled on the support beam 5 from bottom to top. The driving end of the double-headed centering cylinder 12 passes through the second connecting plate 22 and is connected to the first connecting plate 13.

[0057] The spacing area between each top plate 181 and the top surface of the support beam 5 and the spacing area between each top plate 2 151 and the top surface of the support beam 5 are interconnected to form an accommodating groove for accommodating the arc-striking plate 20. The arc-striking plate 20 can be inserted into the accommodating groove from the side of the push member 1 facing away from the push member 2. The width dimension of the arc-striking plate 20 in the front-to-back direction is smaller than the width dimension of the accommodating groove in the front-to-back direction.

[0058] There are multiple elastic members 1, which are elastic telescopic rods 17 extending forward and backward. Two elastic telescopic rods 17 arranged at intervals from top to bottom are connected between each push block 18 and the push block 2 15 on the corresponding side. The elastic telescopic rods 17 can only be retracted when subjected to a large force, so that the two corrugated plates 4 mounted on the support beam 5 can only be squeezed by the two push members 1 on the support beam 5. The squeezing force on the push members 1 is sufficient to retract the elastic telescopic rods 17.

[0059] There are two pressure rods 19, which are respectively installed on the tops of the two pushing blocks 18. The middle part of the pressure rod 19 is rotatably installed on the top plate 181 in the pushing block 18 around the rotation axis extending left and right, and a torsion spring 2 is connected between the pressure rod 19 and the top plate 181, which keeps the pressure rod 19 in a horizontal state.

[0060] There are two push blocks 16, which are respectively mounted on the top plate 2 151 of the two top push blocks 2 15. The side of the push block 16 facing the top push piece 1 is provided with a push inclined surface 161, which is inclined from top to bottom toward the top push piece 1. When the front and rear ends of the two corrugated plates 4 on the support beam 5 are clamped and aligned by the top push piece 1 on the front and rear sides of the support beam 5, the top push piece 2 begins to approach the top push piece 1, so that the push block 16 pushes the pressure rod 19 through the push inclined surface 161, so that the end of the pressure rod 19 facing the top push piece 2 is lifted upward, so that the end of the pressure rod 19 facing away from the top push piece 2 swings downward to press the corrugated plate 4 against the support beam 5.

[0061] like Figure 1 , Figure 2 As shown, the movable frame 3 is installed on the base frame 1, and the movable frame 3 includes a support rail 301 extending forward and backward and supports 302 respectively connected to the bottom of the front and rear ends of the support rail 301. The two supports 302 are respectively spirally mounted on the two driving screws 2. When the driving screw 2 rotates, it can drive the two supports 302 to move forward and backward, thereby driving the support rail 301 to move forward and backward.

[0062] The welding machine is installed on the support rail 301 and can move forward and backward along the support rail 301. The welding machine adopts a submerged arc welding machine. This equipment is a prior art and will not be described in detail here.

[0063] When the present invention is in use, a suspension mechanism is first used to place multiple corrugated plates 4 on multiple sets of transverse clamping mechanisms, and the left and right ends of the corrugated plates 4 are respectively placed on two support blocks 9 in the transverse clamping mechanism, and then the double-head clamping cylinder 8 is started to drive the two support blocks 9 to approach each other, and the clamping arms on both sides to approach each other, and finally the straight rod sections 111 in the clamping arms on both sides are pressed against the straight edges on the left and right sides of the corrugated plates 4, clamping the corrugated plates 4 and aligning the corrugated plates 4 in the front and rear directions.

[0064] After the clamping is completed, the mobile driving mechanism drives each group of transverse clamping mechanisms to move toward the right end of the chassis 1, so that each group of transverse clamping mechanisms approaches each other, and the transverse clamping mechanisms bring multiple corrugated plates 4 to approach each other. During the movement, the support beam 5 first contacts the transverse clamping mechanism on its left side, and then is driven to contact the transverse clamping mechanism on its right side, and is finally clamped by the transverse clamping mechanisms on both sides. During the process of the transverse clamping mechanism and the support beam 5 approaching each other, the driving rod 14 on the support beam 5 is inserted into the corresponding slot, driving the clamping block 11 to rotate, so that the straight rod section 111 rotates to a horizontal state, and the straight rod section 111 is no longer blocked on the outside of the corrugated plate 4, and the transverse clamping mechanism and the support beam 5 continue to approach each other, and the slider 10 is pushed by the support beam 5 and moves toward the inside of the guide hole. In this process, the end of the corrugated plate 4 gradually moves to the top surface of the support beam 5, and finally two corrugated plates 4 are mounted on each support beam 5, and the ends of the two corrugated plates 4 fit each other to achieve the splicing of the corrugated plates 4.

[0065] After the splicing is completed, each group of double-head centering cylinders 12 is started at the same time, and the two groups of clamping components in each group of centering clamping mechanisms are synchronously close to each other. The corrugated plate 4 is first clamped by the two pusher members 1 in the two clamping components to achieve centering, and then the pusher member 2 continues to move toward the pusher member 1, and the push block 16 lifts the end of the pressure rod 19 close to the pusher member 2 upward through the pusher inclined surface 161, driving the other end of the pressure rod 19 to move downward, so that the pressure rod 19 presses the corrugated plate 4 on the support beam 5 from top to bottom, and achieves clamping and fixing of the corrugated plate 4. While the pusher member 2 moves toward the pusher member 1, it pushes the arc-starting plate 20 onto the two corrugated plates 4 after centering, so that the arc-starting plate 20 is pressed against the front and rear side walls of the docking position of the two spliced ​​corrugated plates 4 along the front and rear directions.

[0066] After the fixation is completed, welding can be started. The movable frame 3 moves left and right on the bottom frame 1, moves to each support beam 5 in turn, and makes the welding machine weld the splicing position of the corrugated plate 4, so that multiple corrugated plates 4 are connected into one by welding. When welding, welding starts from one of the arc-starting plates 20 on the support beam 5, passes through the weld formed at the splicing position of the corrugated plate 4, and moves to another arc-starting plate 20 to ensure that the weld position has better welding quality.

[0067] After welding is completed, the centering and clamping mechanism is reset, and the welded corrugated plates 4 are moved to the workstation of the next process using a suspension mechanism. At this time, the winding drum can be controlled to release the pull rope, and the transverse clamping mechanisms and support beams 5 can be manually pushed to reset.

[0068] The present invention can clamp and fix corrugated plates 4 of various sizes, and has a wider application range. It can also clamp and fix multiple corrugated plates 4 at the same time, and can improve processing efficiency.

[0069] In this embodiment, the mobile driving mechanism includes a winding motor and a winding drum. In other embodiments, when the number of corrugated plates 4 to be spliced ​​is small, the mobile driving mechanism can adopt multiple linear driving cylinders arranged in parallel, and the driving output end of the linear driving cylinder is connected to the longitudinal rod 701 in the horizontal clamping mechanism located on the far left.
