[0001] The invention relates to the technical field of welding equipment, in particular to a ladder-type bridge beam manipulator welding auxiliary device and a grasping method thereof. Background Art

[0002] The ladder-type bridge is welded by two groups of cross beams and multiple groups of longitudinal beams. During welding, multiple groups of longitudinal beams are first arranged equidistantly between the two groups of cross beams, and then welding equipment is used to weld the longitudinal beams to the cross beams, finally making the ladder-type bridge.

[0003] When welding ladder bridges, in order to facilitate welding, the longitudinal beams need to be placed equidistantly between two sets of cross beams. After the cross beams and longitudinal beams are positioned equally, the beams are welded with the help of welding equipment. However, at present, the positioning method between the longitudinal beams and the cross beams before welding is usually manual measurement and positioning.

In the initial state, the mounting parts are placed directly above the placement table and close to the placement table. Then the control center is started. Under the drive of the control center, the positioning roller group will first push the beam to the specified position and then stop. Then the control center drives the clamping assembly to clamp the longitudinal beam on the placement table.

DETAILED DESCRIPTION

[0027] Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0028] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0029] In addition, in order to better illustrate the present application, numerous specific details are provided in the specific embodiments below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0030] See also Figure 1-Figure 10 In an embodiment of the present invention, a ladder-type bridge beam manipulator welding auxiliary device comprises: A welding table 1 and a support frame 4, wherein a storage box 3 is disposed on the support frame 4, and a lifting assembly is disposed in the storage box 3, wherein the lifting assembly can drive a lifting member disposed on the storage box 3 to be lifted and lowered in a vertical direction in space; The ladder-type bridge is welded by two groups of cross beams and multiple groups of longitudinal beams. During welding, the multiple groups of longitudinal beams are first arranged equidistantly between the two groups of cross beams, and then the longitudinal beams are welded to the cross beams using a welding device to finally obtain a ladder-type bridge. In an embodiment of the present invention, when welding the ladder-type bridge, the cross beams are placed on a welding table 1, and the longitudinal beams are placed on a placement table 102 next to the welding table 1. During welding, with the aid of the device of the present invention, the longitudinal beams on the placement table 102 can be placed equidistantly between the two groups of cross beams without the need for manual measurement and positioning. With the cooperation of mechanical transmission, the placement of the longitudinal beams is faster and more accurate, providing convenience for the overall welding operation.

[0031] For details, please refer to Figure 1 , Figure 2 The welding table 1 is provided with a positioning roller group 2, and the positioning roller group 2 is provided with multiple groups and symmetrically distributed along the width direction of the welding table 1, and each group of positioning roller group 2 includes two groups of positioning rollers, and the outer ring of the positioning roller is provided with a rubber ring. By providing the rubber ring, the friction between the positioning roller and the crossbeam can be increased, thereby facilitating the subsequent transportation of the crossbeam by the positioning roller group 2.

[0032] In particular, the above-mentioned multiple groups of positioning rollers 2 are controlled by the control center 101 on the welding table 1 at the same time, and can perform synchronous actions. Before the welding operation, the crossbeam is inserted between the two groups of positioning rollers (refer to Figure 1 , insert the crossbeam from the right side), then start the control center 101, under the drive of the control center 101, the positioning roller group 2 moves, at this time, with the cooperation of the rubber ring, the positioning roller group 2 can transport the crossbeam to the left side of the welding table 1.

[0033] The lifting member includes a lifting ring 5, the lifting ring 5 is slidably arranged on the storage box 3, and a lifting plate 16 is arranged on the lifting ring 5; The lifting assembly includes a pulley 14 rotatably mounted in the storage box 3, two groups of pulleys 14 are provided along the longitudinal direction of the storage box 3, a belt 13 is provided between the two groups of pulleys 14, a protruding column 1301 is provided on the belt 13, and the protruding column 1301 is slidably connected to the lifting plate 16; For details, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 The welding table 1 is provided with a placing table 102, the longitudinal beam of the ladder bridge truss is placed on the placing table 102, and the lifting ring 5 is slidably arranged in the through groove 302 provided on the storage box 3, and is fixedly connected with the lifting plate 16; and the lifting plate 16 is provided with a sliding groove 1601 on one side of the storage box 3, and the protruding column 1301 is slidably arranged in the sliding groove 1601; In the initial state, the lifting ring 5 is close to the welding table 1. At this time, the protruding column 1301 is located in the middle section of the slide groove 1601. When the pulley 14 is driven by the outside to drive the belt 13 to rotate continuously in the same direction, the protruding column 1301 can slide in the slide groove 1601. In the process of the sliding of the protruding column 1301, the contact friction between the protruding column 1301 and the groove wall of the slide groove 1601 can drive the lifting plate 16 to slide along the height direction of the storage box 3, and then drive the lifting ring 5 away from or close to the welding table 1. In the process of the lifting ring 5 being lifted and lowered, the clamping assembly arranged on the lifting ring 5 can first clamp or release the longitudinal beam on the placement table 102, so that the lifting ring 5 can complete the transfer operation of the longitudinal beam on the placement table 102 during the lifting and lowering process, thereby facilitating the subsequent welding device to weld the cross beam and the longitudinal beams.

[0034] The lifting member is rotatably mounted with a mounting member 7, and the mounting member 7 is provided with a clamping assembly, and the clamping assembly is communicatively connected with a control center 101 provided on the welding table 1. When the lifting member approaches the welding table 1, the control center 101 can drive the clamping assembly to clamp or release the longitudinal beam; and the mounting member 7 is connected with a deflection assembly provided on the support frame 4; For details, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 A rotating ring 6 is installed on the lifting ring 5, a connecting frame 601 is provided on the rotating ring 6, the mounting member 7 is arranged on the connecting frame 601, and a plug-in tube 602 is provided on the connecting frame 601. Due to the cooperation between the lifting ring 5 and the rotating ring 6, the mounting member 7 can rotate relative to the lifting ring 5, so that the mounting member 7 can be transferred from the top of the placement table 102 to the top of the welding table 1. At the same time, with the cooperation of the clamping assembly and the lifting assembly, the purpose of transferring the longitudinal beam on the placement table 102 to between the two groups of cross beams on the welding table 1 can be achieved, thereby completing the positioning between the longitudinal beam and the cross beam.

[0035] For further information, see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 The clamping assembly includes a trigger structure and a bidirectional moving structure. The trigger structure includes two groups of deflection plates 20 symmetrically mounted on the mounting member 7. A slide rail 25 is provided on one side of each group of deflection plates 20, and a trigger rod 2001 is provided on the other end away from the mounting member 7. The two groups of slide rails 25 are connected by a driving member. The driving member includes a cylinder 8 disposed on a mounting member 7, a driving plate 19 is disposed at the telescopic end of the cylinder 8, two sets of pulleys 1901 are symmetrically disposed on the driving plate 19, and the two sets of pulleys 1901 are slidably disposed in the slide rail 25 respectively; Preferably, a bracket 701 is provided on the above-mentioned mounting member 7, and a cylinder 8 is provided on the bracket 701, and the cylinder 8 is communicatively connected with a second sensor 702 provided on the mounting member 7. In the initial state, the above-mentioned driving plate 19 is close to the mounting member 7. At this time, the pulley 1901 is located at the stroke end of the slide rail 25 close to the mounting member 7, and the two groups of deflection plates 20 are away from each other and are in an open state. When the second sensor 702 receives a feedback signal from the control center 101 and drives the cylinder 8 to operate, the telescopic end of the cylinder 8 can push the driving plate 19 to move in the vertical direction of the space toward the direction away from the mounting member 7. In this process, since the length of the driving plate 19 is constant, the pulley 1901 moving in the slide rail 25 can drive the two groups of deflection plates 20 to deflect towards each other. At the same time, the deflection plate 20 can drive the bidirectional movable structure to approach each other, thereby clamping the longitudinal beam.

[0036] The bidirectional moving structure comprises a fixed box 9 arranged on the mounting member 7, two sets of deflection slots 901 are symmetrically opened on one side of the fixed box 9 facing the deflection plate 20, and a bidirectional moving member is slidably arranged in the fixed box 9; In particular, see Figure 7 , Figure 8 The center of the deflection groove 901 is concentric with the deflection center of the deflection plate 20, and the radius of the deflection groove 901 is equal to the distance between the trigger rod 2001 and the rotation axis of the deflection plate 20. Therefore, when the deflection plate 20 rotates and deflects, the trigger rod 2001 can slide in the deflection groove 901, thereby cooperating with the bidirectional moving part to drive the bidirectional moving part to move closer to or away from each other, so as to clamp or release the longitudinal beam.

[0037] The bidirectional moving member comprises two groups of moving rods 10 symmetrically slidably arranged, each group of the moving rods 10 is provided with a vertical slot 1001, and the trigger rod 2001 is slidably arranged in the deflection slot 901 and placed in the vertical slot 1001; For details, please refer to Figure 8 The moving rod 10 is slidably arranged in the moving groove 902 opened on the fixed box 9. Under the restriction of the moving groove 902, the moving rod 10 can only slide along the length direction of the fixed box 9, and a clamping plate 1002 is arranged at the end of the moving rod 10 away from the fixed box 9. A silicone pad is arranged on the inner side of the clamping plate 1002. The silicone pad can increase the contact friction between the clamping plate 1002 and the longitudinal beam, so that when the clamping plate 1002 clamps the longitudinal beam, the longitudinal beam will not easily fall off from between the two sets of clamping plates 1002.

[0038] The deflection structure includes a turntable 12 rotatably mounted on the support frame 4, a connecting rod 11 is provided on the turntable 12, the connecting rod 11 passes through the support frame 4, is placed in an arc groove 401 provided on the support frame 4, and one end of the connecting rod 11 away from the turntable 12 is connected to the mounting member 7, in detail, one end of the connecting rod 11 away from the turntable 12 is inserted into the plug-in tube 602; See also Figure 1 , Figure 2 , Figure 7 , Figure 8 , Fig. 9 In the initial state, the trigger rod 2001 is located at the upper end of the vertical slot 1001 (the end away from the clamping plate 1002). In combination with the above, when the deflection plate 20 is driven by the lifting plate 16 to deflect towards each other, the trigger rod 2001 can slide in the deflection slot 901. During this process, the trigger rod 2001 can slide along the vertical slot 1001 toward the clamping plate 1002. During the sliding process, the contact and compression of the trigger rod 2001 on the wall of the vertical slot 1001 can drive the two groups of moving rods 10 to approach each other, thereby clamping the longitudinal beam on the placement table 102; on the contrary, when the deflection plate 20 is controlled by the lifting plate 16 to move away from each other, the cooperation between the trigger rod 2001 and the vertical slot 1001 can drive the two groups of clamping plates 1002 to move away from each other, thereby releasing the clamped longitudinal beam.

[0039] It also includes a driving assembly, which is arranged on the storage box 3, connected to the lifting assembly and the deflection assembly, and can drive the lifting assembly and the deflection assembly to perform alternating actions, so as to transfer the longitudinal beam placed on the support frame 4 to the welding table 1; The drive assembly includes a Maltese cross movement; The Maltese cross movement includes a driving wheel 23 rotatably mounted on the storage box 3, a first driven wheel 22 and a second driven wheel 24, the first driven wheel 22 is connected to a linkage rod 15 rotatably mounted on the support frame 4 through a bevel gear set 21, and the linkage rod 15 is connected to the rotating shaft of the turntable 12 through a linkage belt; For details, please refer to Figure 1 , Figure 2 , Figure 3 , Fig.10The driving wheel 23 is coaxially fixedly connected with the output shaft of the servo motor arranged on the storage box 3, and the servo motor is in communication connection with the first sensor 301 fixedly installed on the storage box 3, and a driving rod 2301 is formed on the side of the driving wheel 23 away from the servo motor, and the first driven wheel 22 and the second driven wheel 24 are equidistantly provided with four groups of grooves along their circumferential direction, when the driving wheel 23 is driven by the servo motor to continuously rotate in the same direction for one circle, the driving rod 2301 can be combined with the grooves on the first driven wheel 22 and the second driven wheel 24 in turn, and when the driving rod 2301 is combined with the groove, the driving wheel 23 can drive the first driven wheel 22 and the second driven wheel 24 to rotate a quarter of a circle in the same direction as the driving wheel 23; The bevel gear set 21 includes a first bevel gear and a second bevel gear, wherein the first bevel gear is coaxially fixedly connected to the first driven wheel 22, and the second bevel gear is coaxially fixedly connected to the linkage rod 15; The second driven wheel 24 is coaxially provided with a first linkage wheel 17, the first linkage wheel 17 is connected to the second linkage wheel 18 through a transmission belt, and the second linkage wheel 18 is coaxially fixed to one set of the pulleys 14; It should be noted that the radius of the first interlocking wheel 17 is a multiple of the radius of the second interlocking wheel 18, so that when the first interlocking wheel 17 rotates synchronously with the second driven wheel 24 for a quarter of a circle, the first interlocking wheel 17 can drive the second interlocking wheel 18 to rotate multiple circles, so that the belt 13 can just drive the lifting plate 16 to move a travel distance, lifting the lifting plate 16 from the lowest point to the highest point, or lowering it from the highest point to the lowest point, so that the clamping assembly can transfer the longitudinal beam.

[0040] In combination with the above, in the initial state, the mounting member 7 is placed just above and close to the placement table 102. When welding the ladder bridge, first connect the two sets of cross beams to the positioning roller set 2 on the welding table 1, then place the longitudinal beam on the placement table 102, and then start the control center 101; Then, the control center 101 can drive the positioning roller group 2 to move, pushing the crossbeam to move toward the left side of the welding table 1 (refer to Figure 1 Description), after moving a certain distance (the distance can be adjusted by the control center 101), the positioning roller group 2 stops moving, and then the control center 101 sends a signal to the second sensor 702 to drive the cylinder 8 to push the driving plate 19 down. At this time, the descending driving plate 19 can drive the two groups of deflection plates 20 to approach each other with the cooperation of the pulley 1901 and the slide rail 25, and then drive the two groups of clamping plates 1002 to approach each other to clamp the longitudinal beam on the placement table 102. After the longitudinal beam is clamped stably, the control center 101 sends a signal to the first sensor 301 to drive the servo motor to drive the driving wheel 23 to rotate counterclockwise; At this time, the counterclockwise rotating driving wheel 23 first enters the transmission state with the second driven wheel 24, which can drive the first linkage wheel 17 to rotate counterclockwise (refer to Figure 1 Description), then the first linkage wheel 17 drives the pulley 14 to rotate counterclockwise, and under the cooperation of the protruding column 1301 and the lifting plate 16, the lifting ring 5 drives the rotating ring 6 and the mounting member 7 holding the longitudinal beam to gradually move away from the placement table 102. At this time, the plug-in cylinder 602 can slide relative to the connecting rod 11 until the lifting ring 5 moves to the highest point, and the driving wheel 23 and the second driven wheel 24 are out of the transmission state. With the continued rotation of the driving wheel 23, the driving wheel 23 can enter the transmission state with the first driven wheel 22; Then, the first driven wheel 22 rotating counterclockwise can drive the linkage rod 15 to rotate ninety degrees clockwise under the connection action of the bevel gear set 21. At the same time, the linkage rod 15 can drive the turntable 12 to rotate ninety degrees under the connection action of the linkage belt, and rotate the mounting member 7 holding the longitudinal beam to the top of the welding table 1, so that the longitudinal beam and the width direction of the welding table 1 remain parallel. Then, the driving wheel 23 separates from the first driven wheel 22, and then combines with the second driven wheel 24 again, and then drives the lifting ring 5 to drive the mounting member 7 holding the longitudinal beam to approach the welding table 1, until the lifting ring 5 drops to the lowest point, and the servo motor output shaft pauses. During this process, the control center 101 sends a signal to the second sensor 702, which can drive the cylinder 8 to retract, thereby driving the two groups of clamping plates 1002 away from each other, and releasing the longitudinal beam between the two groups of cross beams. After the output shaft of the servo motor stops, the output shaft of the servo motor reverses, and the driving wheel 23 can first be combined with the second driven wheel 24 to drive the lifting ring 5 to drive the mounting member 7 to rise, and then the driving wheel 23 is combined with the first driven wheel 22 to drive the turntable 12 to drive the mounting member 7 to rotate ninety degrees and return to the top of the placement table 102, and then the driving wheel 23 can be combined with the second driven wheel 24 again to drive the lifting ring 5 to drive the mounting member 7 to descend to the initial position, so that the longitudinal beam can be clamped again at the next place, and in the process of the driving wheel 23 and the second driven wheel 24 combining again, the welding device (not shown in the figure) arranged on the welding table 1 can weld between the crossbeam and the longitudinal beam on the welding table 1; After the mounting part 7 returns to the initial state, the control center 101 drives the servo motor and the cylinder 8 to repeat the above process, so that the longitudinal beam can be placed equidistantly between the two sets of cross beams. There is no need for manual measurement and positioning, the error is small, the overall operation is simple, and the welding efficiency is relatively high.

[0041] The present invention also proposes a grasping method of a ladder-type bridge beam manipulator welding auxiliary device, which adopts the ladder-type bridge beam manipulator welding auxiliary device as described above, and comprises the following steps: Step 1: Use the positioning roller group 2 on the welding table 1 to clamp and fix the two groups of beams. In the initial state, the mounting member 7 is placed directly above the placement table 102 and close to the placement table 102. Then, the control center 101 is started. Under the drive of the control center 101, the positioning roller group 2 will first push the beam to the specified position and then stop. Then, the control center 101 drives the clamping assembly to clamp the longitudinal beam on the placement table 102. Step 2: After the clamping is completed, the control center 101 drives the servo motor to move, and then the driving component first drives the lifting component to move, driving the lifting ring 5 and the longitudinal beam to rise, until the lifting ring 5 rises to the highest point, and then the driving component drives the deflection component to move; Step 3: When the deflection assembly is in motion, it can drive the mounting member 7 to rotate 90 degrees relative to the storage box 3, and then the driving assembly is separated from the deflection assembly, and cooperates with the lifting assembly again to drive the lifting ring 5 to descend; Step 4: When the lifting ring 5 descends to be close to the welding table 1 , the control center 101 drives the clamping assembly to release the longitudinal beam, thereby transferring the longitudinal beam from the placement table 102 to the welding table 1 .
