Description

Technical Field

[0001] The invention relates to the technical field of cabin section riveting tooling, and in particular to a horizontal riveting jig. Background Art

[0002] Large-diameter, circular-shaped riveted parts are used in the aerospace field. They require horizontal riveting jigs for assembly. Figure 1 As shown, the foundation is cast from reinforced concrete, and then the ground rails are laid. To ensure the stability of the ground rails, another layer of reinforced concrete is cast to bury the lower half of the ground rails. The ground rails are also connected to fixed flanges and movable flanges through a base. The fixed flange is fixed to the foundation through the base, and the movable flange can slide on the ground rails with the base. To facilitate the entry and exit of operators, the traditional horizontal riveting jig is also equipped with a bridge, which extends into the flange. When assembling a large-diameter cylindrical riveted part, first place four 1 / 4 riveted parts between two flanges. Then, on the horizontal riveting jig, the fixed beams at the edge of each 1 / 4 riveted part are riveted to each other to assemble the large-diameter cylindrical riveted part.

[0003] However, the two flanges of traditional horizontal riveting jigs cannot rotate. When assembling large-diameter cylindrical riveted parts, due to their larger diameter, it is inconvenient for operators to directly assemble the top of the large-diameter cylindrical riveted parts. Therefore, they can only assemble four 1 / 4 riveted parts first, and then rivet the edge fixing beams of the four 1 / 4 riveted parts to form the large-diameter cylindrical riveted part. Moreover, the flange is supported only by the base, and the assembly contact surface of the flange is not completely perpendicular to the horizontal plane. It may be "drooping" or "tilting up", resulting in large errors. Summary of the Invention

[0024] The present invention has the following beneficial effects:

[0025] (1) The two flanges in the flange assembly of the present invention can be rotated, thereby adjusting the position of the large-diameter cylindrical rivet, facilitating the direct assembly of the large-diameter cylindrical rivet, and reducing the assembly process. At the same time, the rotating shafts of the two flanges can be connected together through a docking mechanism to achieve linkage between the two flanges, so that the torsion of the two flanges after rotation can be kept within an acceptable range.

[0026] (2) The first telescopic shaft assembly and the second telescopic shaft assembly of the present invention can be accommodated in the rotating shafts of the two flanges. When not docked, the first telescopic shaft assembly and the second telescopic shaft assembly are respectively hidden in the rotating shafts of the two flanges, and will not hinder the assembly of the large-diameter cylindrical rivet. When docking is required, the first telescopic assembly and the second telescopic assembly are respectively extended from the rotating shafts of the two flanges and connected, thereby realizing linkage adjustment.

[0027] (3) The flange of the present invention is connected to the housing through a rotating shaft, so that the entire flange can be rotated. The outer ring of the flange wraps around the inner ring of the flange and is connected through a flange fastening ring, thereby improving the connection reliability between the outer ring of the flange and the inner ring of the flange. The circumferential positioning ring of the flange is used to contact the balancing support mechanism, and the balancing support mechanism balances the gravity of the flange, the gravity of the large-diameter cylindrical riveted parts, and the gravity of the internal operator, thereby avoiding the flange from "drooping" or "raising".

[0028] (4) The adjustment component of the present invention can adjust the height of the balancing bracket, which is convenient for the installation of the entire balancing support mechanism (after the installation is completed, the balancing roller is brought into contact with the flange through the adjustment component). In addition, the support strength of the flange can also be adjusted. The entire support process is convenient, simple and fast.

[0029] (5) The first suspension frame and the second suspension frame of the retractable corridor bridge of the present invention are respectively connected to the two rotating shafts, and the sliding fit between the first frame and the second frame enables the entire corridor bridge to be retracted and adapted to the movement of the movable flange assembly. The retractable corridor bridge is always maintained between the fixed flange assembly and the movable flange assembly. Compared with the existing corridor bridge passing through the flange, the corridor bridge will not extend out of the flange, reducing the installation site of the horizontal riveted frame, simplifying the connection method of the corridor bridge, and the overall assembly of the corridor bridge is simple and quick.

[0030] (6) The top surfaces of the first support frame and the second support frame in the retractable corridor bridge of the present invention are stepped from both sides to the middle, so that the corridor bridge has multiple working surfaces at different heights, which is convenient for operators to stand on different working surfaces to operate. Moreover, this distribution method is compatible with large-diameter cylindrical riveted parts and is suitable for assembling large-diameter cylindrical riveted parts.

DETAILED DESCRIPTION

[0055] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0056] Please refer to Figure 2A horizontal riveting jig includes: a base 10, a fixed flange assembly 201, a movable flange assembly 202, a docking mechanism 24, a rotary power assembly 26, and a retractable gallery 40. The fixed flange assembly 201 and the movable flange assembly 202 are respectively arranged on the top of the base 10 via a box 22. Two parallel slide rails 11 are provided on the top of the base 10. The bottom of the box 22 connected to the movable flange assembly 202 is provided with a slot that cooperates with the slide rails 11, allowing the movable flange assembly 202 to move on the top of the base 10 toward the direction where the fixed flange assembly 201 is located. The docking mechanism 24 is connected to the rotating shaft 21 of the fixed flange assembly 201 and the movable flange assembly 202 respectively, so that the flanges 23 of the fixed flange assembly 201 and the movable flange assembly 202 can be linked. When assembling the large-diameter cylindrical riveted parts, the top side of the large-diameter cylindrical riveted parts can be rotated to a position that is convenient for riveting, thereby directly assembling the large-diameter cylindrical riveted parts and reducing the assembly process. The rotating power assembly 26 is connected to the fixed flange assembly 201 and is used to drive the fixed flange assembly 201 and the movable flange assembly 202 to be linked. The two ends of the retractable gallery 40 are connected to the rotating shaft 21 of the fixed flange assembly 201 and the movable flange assembly 202 respectively, so that the retractable gallery 40 is suspended and arranged between the fixed flange assembly 201 and the movable flange assembly 202, and the retractable gallery 40 can adapt to the change of the distance between the fixed flange assembly 201 and the movable flange assembly 202.

[0057] In this embodiment, the movable flange assembly 202 is connected to the base 10 via a drive assembly 27. The drive assembly 27 includes a drive motor 271, a gear 272, and a rack 273. The drive motor 271 is fixedly mounted on the bottom of the housing 22 connected to the movable flange assembly 202. The rack 273 is fixedly mounted on the base 10 and is located between the two slide rails 11. The rack 273 is parallel to the slide rails 11. The gear 272 meshes with the rack 273, and driven by the drive motor 271, the movable flange assembly 202 moves along the slide rails 11.

[0058] Please refer to Figure 3 The housing 22 comprises a lower housing 221 and an upper housing 222 connected by bolts. Housing end covers 223 are provided on opposite sides of the housing 22. These end covers 223 are located at the junction between the lower housing 221 and the upper housing 222. The housing end covers 223 allow the shaft 21 to pass through and support the shaft 21. The shaft 21 can rotate in conjunction with the two housing end covers 223.

[0059] Please refer to Figure 4The fixed flange assembly 201 and the movable flange assembly 202 have the same structure and are axially opposed to each other. They both include a rotating shaft 21, a flange 23 mounted on the rotating shaft 21, and a brake 29 connected to the rotating shaft 21. The rotating shaft 21 rotates with the corresponding housing end cover 223 via a rotating bearing. The flange 23 is located on the front of the housing 22 (the sides of the two housings 22 facing each other are the front, and the sides away from each other are the back). The brake 29 is an electromagnetic encircling brake located inside the corresponding housing 22.

[0060] In this embodiment, the rotating shafts 21 of the fixed flange assembly 201 and the movable flange assembly 202 are arranged opposite to each other and their axes coincide with each other, and the front faces of the flanges 23 of the fixed flange assembly 201 and the movable flange assembly 202 are opposite to each other.

[0061] Please refer to Figure 5 and Figure 6 The flange 23 includes an outer flange ring 231 and an inner flange ring 232. Due to the larger diameter of large-diameter cylindrical rivets, the volume of a conventional horizontal riveting jig is relatively large. Therefore, the flange of a conventional horizontal riveting jig is composed of four 1 / 4 sector-shaped units. In this embodiment, the outer flange ring 231 is also composed of four outer ring units 233. The four outer ring units 233 are sector-shaped and can form a complete ring. The inner flange ring 232 is wrapped by the four outer ring units 233. The integral inner flange ring 232 facilitates direct connection to the rotating shaft 21.

[0062] In this embodiment, adjacent outer ring units 233 are positioned by pins and fixedly connected by bolts, and the flange inner ring 232 and all outer ring units 233 are positioned by pins and fixedly connected by bolts.

[0063] In other embodiments of the present invention, the number of outer ring units 233 may be determined according to actual conditions, such as 3, 5, 6, etc.

[0064] The outer ring unit 233 comprises a connecting block 2331, a positioning block 2332, and a fastening block 2333, all connected in sequence from the outside to the inside and all in an arcuate shape. The positioning block 2332 extends out of one side of the connecting block 2331. A flange circumferential positioning ring 234 is sleeved around the outer side of each positioning block 2332. A flange fastening ring 235 is sleeved around the outer side of each fastening block 2333 to enhance the connection between the outer flange ring 231 and the inner flange ring 232. In this embodiment, the flange circumferential positioning ring 234 is located outside the flange fastening ring 235.

[0065] In order to facilitate the entry and exit of operators, in this embodiment, multiple passages for workers to pass through are provided between the connecting block 2331 and the positioning block 2332, between the positioning block 2332 and the fastening block 2333, and inside the flange inner ring 232. Specifically, the connecting block 2331 and the positioning block 2332, and between the positioning block 2332 and the fastening block 2333 are connected by reinforcing ribs, and reinforcing ribs are also provided inside the flange inner ring 232.

[0066] In this embodiment, the flange circumferential positioning ring 234 is located on the back side of the flange plate 23, and a scale is provided on the flange circumferential positioning ring 234. The corresponding outer side of the box body 22 is provided with a circumferential positioning pointer 203. The circumferential positioning pointer 203 corresponds to the scale of the corresponding flange circumferential positioning ring 234, and is used to indicate the position of the corresponding flange plate 23 after rotation.

[0067] Please refer to Figure 7 In order to prevent the flange 23 from "drooping" or "raising its head", in this embodiment, a counterweight ring 28 is provided on the rotating shaft 21, and the counterweight ring 28 and the corresponding flange 23 are respectively located on both sides of the corresponding box body 22. At the same time, a balancing support mechanism 25 is provided on the outer side of the bottom of the box body 22 for contacting the corresponding flange circumferential positioning ring 234.

[0068] Please refer to Figures 8 to 13 The balancing support mechanism 25 includes a balancing base 251, a balancing bracket 252, a balancing roller 253, and an adjustment assembly 254. The bottom of the balancing bracket 252 is placed on the balancing base 251. The top of the balancing bracket 252 is provided with a balancing roller 253 for contacting the flange circumferential positioning ring 234 on the flange 23. The bottom of the balancing bracket 252 is provided with a positioning cylinder 2521, which passes through the balancing base 251 and slidably cooperates with the balancing base 251. The adjustment assembly 254 is located at the bottom of the balancing base 251 and contacts the positioning cylinder 2521. It is used to adjust the height of the balancing bracket 252, so that the balancing roller 253 contacts the flange circumferential positioning ring 234 and supports the flange 23.

[0069] Please refer to Figure 6 The balancing base 251 is door-shaped, and the bottom cavity thereof is used to place the adjustment component 254 . The bottom of the balancing base 251 is provided with bolt holes for fixing the balancing base 251 to the box body 22 .

[0070] Please refer to Figure 5 and Figure 7There are two sets of balancing rollers 253, located at either end of the balancing bracket 252 and parallel to each other. Each set of balancing rollers 253 is connected to the balancing bracket 252 via a roller seat 255. Specifically, the balancing rollers 253 are rotatably connected to the roller seat 255 via a balancing roller pin 256. A positioning rod 257 is provided at the bottom of the roller seat 255, which slides into the balancing bracket 252. To prevent the roller seat 255 from rotating, in other embodiments of the present invention, the contact points between the roller seat 255 and the balancing bracket 252 are mortise and tenon-jointed.

[0071] Please refer to Figures 8 to 10 The adjustment assembly 254 includes a lower wedge block 2541, an upper wedge block 2542, and an adjustment support block 2543. The top surface of the lower wedge block 2541 and the bottom surface of the upper wedge block 2542 are both inclined surfaces with the same inclination angle. When the two inclined surfaces cooperate with each other, the bottom surface of the lower wedge block 2541 and the top surface of the upper wedge block 2542 are in a horizontal state. The adjustment support block 2543 is connected to the end of the lower wedge block 2541 with a larger cross-section. The adjustment support block 2543 is connected to the end of the upper wedge block 2542 with a smaller cross-section via an adjustment bolt 2544. In this embodiment, the adjustment support block 2543 and the lower wedge block 2541 are integrally formed.

[0072] The specific connection method of adjusting bolt 2544 is as follows: a limiting groove 2545 is provided on the top of adjusting support block 2543. The head of adjusting bolt 2544 is stuck in limiting groove 2545 and can slide vertically in limiting groove 2545 to adjust to the height change of upper wedge block 2542. The limiting groove 2545 on both sides of the adjusting bolt 2544 can prevent the upper wedge block 2542 from separating from the lower wedge block 2541.

[0073] The top surface of the upper wedge block 2542 contacts the positioning cylinder 2521. When the adjusting bolt 2544 is screwed, it will cause the upper wedge block 2542 and the lower wedge block 2541 to slide relative to each other, thereby changing the height of the upper wedge block 2542, and then changing the height of the balance bracket 252, which facilitates the installation of the entire balance support mechanism 25 and facilitates the adjustment of the support force of the flange 23.

[0074] In order to reduce friction during height adjustment, in this embodiment, the lower wedge block 2541 is provided with a groove 2546 in the vertical direction, and the upper wedge block 2542 is provided with a through groove 2547 along the vertical direction, thereby reducing friction by reducing the contact area.

[0075] In order to avoid interference with the flange 23 , in this embodiment, the middle portion of the top surface of the balance bracket 252 is recessed downward to clear the edge of the flange circumferential positioning ring 234 .

[0076] In this embodiment, the vertical displacement of the flange 23 can be adjusted by adding or removing the counterweight ring 28, thereby adjusting the coaxiality between the two flanges 23 of the horizontal riveted frame. The flange circumferential positioning ring 234 of the balancing support mechanism 25 is in contact with the balancing roller 253. By screwing the adjusting bolt 2544, the support force of the balancing roller 253 on the flange 23 can be adjusted, and the vertical displacement of the flange 23 can also be adjusted. Therefore, the combined action of the counterweight ring 28 and the balancing support mechanism 25 can adjust the vertical displacement of the flange 23, thereby adjusting the coaxiality between the two flanges 23 of the horizontal riveted frame. Since the flange 23 can rotate with the rotating shaft 21, the torsion between the two flanges 23 can be adjusted.

[0077] Please refer to Figures 14 to 17 The docking mechanism 24 includes a first telescopic shaft assembly 241 and a second telescopic shaft assembly 242 that are axially opposed to each other, i.e., the axes of the first telescopic shaft assembly 241 and the second telescopic shaft assembly 242 coincide with each other. The first telescopic shaft assembly 241 and the second telescopic shaft assembly 242 are respectively installed in the rotating shafts 21 of the fixed flange assembly 201 and the movable flange assembly 202. When not extended, the first telescopic shaft assembly 241 and the second telescopic shaft assembly 242 are stored in the corresponding rotating shafts 21. When extended, they extend from the corresponding rotating shafts 21 and dock together, allowing the first telescopic shaft assembly 241 and the second telescopic shaft assembly 242 to work in conjunction with each other to ensure that the torsion degree of the flange 23 is within the acceptable range when it rotates.

[0078] The structures of the first telescopic shaft assembly 241 and the second telescopic shaft assembly 242 are consistent. In this embodiment, only the structure of the first telescopic shaft assembly 241 is described.

[0079] The first telescopic shaft assembly 241 includes a cylinder 243, a support sleeve 244, a telescopic shaft 245, and a connecting sleeve 246. The cylinder 243 comprises a cylinder body 2431 and a push rod 2432. The push rod 2432 extends from the cylinder body 2431. Under the action of air pressure, the push rod 2432 can slide with the cylinder body 2431, thereby extending or retracting the push rod 2432. The end of the cylinder body 2431 away from the push rod 2432 is bolted to a tailstock 2433. The tailstock 2433 is bolted to the corresponding rotating shaft 21, securing the cylinder 2433 within the corresponding rotating shaft 21.

[0080] A connecting ring is provided at each end of the support sleeve 244. The connecting ring is cold-installed into the interior of the rotating shaft 21 corresponding to the flange 23. In this embodiment, the support sleeve 244 and the tailstock 2433 are respectively mounted on the respective ends of the rotating shaft 21. A centering ring 247 is connected to each end of the support sleeve 244. Specifically, the centering ring 247 is bolted to the corresponding connecting ring. A slider 2441 is provided on the inner side of the support sleeve 244, extending in the axial direction.

[0081] The telescopic shaft 245 includes a connecting end 2451 and a free end 2452. A sliding groove 2453 is provided on the outer side of the telescopic shaft 245. When the telescopic shaft 245 passes through the support sleeve 244, the sliding groove 2453 of the telescopic shaft 245 engages with the slider 2441, limiting the circumferential rotation between the telescopic shaft 245 and the support sleeve 244. Furthermore, the telescopic shaft 245 slides with the centering ring 247, which ensures that the axis of the telescopic shaft 245 coincides with the axis of the support sleeve 244, thereby ensuring that the axis of the telescopic shaft 245 coincides with the axis of the rotating shaft 21 of the corresponding flange 23. The connecting end 2451 is connected to the connecting sleeve 246 via a cylinder push block 248. Specifically, the cylinder push block 248 is mounted on the connecting sleeve 246, and the telescopic shaft 245 is mounted on the cylinder push block 248. The three components are fixedly connected by bolts. The push rod 2432 extends from the cylinder body 2431 and is fixedly connected to the cylinder push block 248. The push rod 2432 drives the cylinder push block 248, the telescopic shaft 245 and the connecting sleeve 246 to move.

[0082] In this embodiment, both ends of the chute 2453 are sealed, and one end is sealed by a stopper 2454, which is fixed to the chute 2453 by bolts. By sealing both ends of the chute 2453, the slider 2441 can be restrained in the chute 2453, ensuring that the telescopic shaft 245 does not separate from the support sleeve 244. The provision of the stopper 2454 facilitates the installation of the telescopic shaft 245 and the support sleeve 244.

[0083] In this embodiment, the connecting sleeve 246 is provided with a plurality of through holes, and the connecting sleeves 246 of the first telescopic shaft assembly 241 and the second telescopic shaft assembly 242 are connected to each other through bolts, pins, etc. located in the through holes.

[0084] When docking is not required, the first telescopic shaft assembly 241 and the second telescopic shaft assembly 242 of this embodiment are respectively housed in the rotating shaft 21 of the corresponding flange 23. When docking is required, the cylinder 243 extends the telescopic shaft 245 to make the connecting sleeves 246 of the first telescopic shaft assembly 241 and the second telescopic shaft assembly 242 contact each other, and fix them by bolts or pins to achieve docking of the two connecting sleeves 246, thereby connecting the two flanges 23 together and realizing the linkage of the two flanges 23 to ensure that the torsion degree of the flange 23 is within the qualified range when rotating.

[0085] Please refer to Figure 18The rotating power assembly 26 includes a bracket 261 fixed to other components of the horizontal riveting jig, a power motor 262 fixedly mounted on the bracket 261, a drive sprocket 263 connected to the power motor 262, and a driven sprocket 264 connected to the drive sprocket 263 via a chain 204. The driven sprocket 264 is mounted on the rotating shaft 21 of the fixed flange assembly 201. The drive sprocket 263 is fixed to the bracket 261 via a rotating bearing. In this embodiment, the diameter of the drive sprocket 263 is smaller than that of the driven sprocket 264.

[0086] To ensure that the chain 204 can effectively transmit power, in this embodiment, the rotary power assembly 26 further includes a vertical shaft 265 fixed to the bracket 261, a tensioning adjustment block 266 threadedly connected to the vertical shaft 265, a tensioning rocker arm 267 sleeved on the vertical shaft 265 and located on the bottom side of the tensioning adjustment block 266, and a tensioning pulley 268 connected to the tensioning rocker arm 267 and in contact with the bottom inner side of the chain 204. A tensioning spring 269 is also sleeved on the vertical shaft 265 and located between the bracket 261 and the tensioning rocker arm 267. When the chain 204 becomes loose, the tensioning adjustment block 266 is rotated to cause the tensioning rocker arm 267 to slide downward on the vertical shaft 265, compressing the tensioning spring 269. The tensioning rocker arm 267 then drives the tensioning pulley 268 downward, thereby tightening the chain 204.

[0087] Please refer to Figures 19 to 23 The retractable corridor bridge 40 of this embodiment is divided into two parts, which are respectively suspended on the rotating shaft 21 of the fixed flange assembly 201 and the movable flange assembly 202. The two parts can move closer to or away from each other, so that the entire corridor bridge can be retracted and retracted, thereby adapting to the change in the distance between the two flanges 23 due to the movement of the movable flange assembly 202.

[0088] The retractable covered bridge 40 of this embodiment includes a first suspension frame 41 and a second suspension frame 42 of identical structure and opposite orientation, and a pedal assembly 43 disposed between the first and second suspension frames 41, 42. The pedal assembly 43 forms a work surface for an operator to stand on. The pedal assembly 43 comprises two parts, each fixedly connected to the first and second suspension frames 41, 42, respectively. The two parts can slide relative to each other, thereby increasing or decreasing the distance between the first and second suspension frames 41, 42, and thus achieving the overall extension and retraction of the covered bridge.

[0089] Please refer to Figures 3 to 5The first suspension bracket 41 and the second suspension bracket 42 are respectively suspended on the rotating shaft 21 of the fixed flange assembly 201 and the movable flange assembly 202. The first support bracket 411 and the second support bracket 421 are respectively connected to the first support bracket 411 and the second support bracket 421 near the bottom. The first support bracket 411 and the second support bracket 421 have the same structure and are in opposite directions, and the first support bracket 411 and the second support bracket 421 are arranged relative to each other. In this embodiment, the first suspension bracket 41 and the second suspension bracket 42 have the same structure and are in opposite directions. The first support bracket 411 and the second support bracket 421 have the same structure and are in opposite directions. Therefore, this embodiment only describes the structure of the first suspension bracket 41.

[0090] The top of the first suspension bracket 41 is provided with a through hole for being mounted on the rotating shaft 21, and the first suspension bracket 41 can rotate on the rotating shaft 21. When the flange 23 is adjusted, the position of the pedal assembly 43 will not change significantly. The edge of the first suspension bracket 41 connected to the first support bracket 411 is provided with a plurality of support blocks 412. Specifically, the support blocks 412 are arranged on the vertical side edges and the bottom edge of the first suspension bracket 41. At the same time, the support blocks 412 on both sides of the first suspension bracket 41 correspond to each other. The bottom of the first suspension bracket 41 is provided with a clamping block 413, and the extension direction of the clamping block 413 is consistent with the extension direction of the support block 412. The support block 412 and the clamping block 413 are used to support the first support bracket 411. During assembly, the first support bracket 411 can be directly placed on the support block 412 and the clamping block 413, and the disassembly and assembly process is simple and quick.

[0091] In order to prevent the first support frame 411 from falling off the support block 412 and the clamping block 413, in this embodiment, a baffle 416 is provided on the support block 412. The baffle 416 is arranged opposite to the first suspension frame 41, and the first support frame 411 is clamped between the baffle 416 and the first suspension frame 41.

[0092] The top surface of the first support frame 411 is stepped from both sides toward the center, forming multiple work surfaces of varying heights when connected to the pedal assembly 43. Mounting blocks 414 are provided on the sides of the first support frame 411, corresponding one-to-one with the support blocks 412. These mounting blocks 414 are placed on the corresponding support blocks 412 and blocked by baffles 416. A slot 415 corresponding to the locking block 413 is defined at the bottom of the first support frame 411, allowing the first support frame 411 to engage with the first suspension frame 41.

[0093] Please refer to Figure 2 and Figure 6The pedal assembly 43 includes a plurality of first frames 431 and a plurality of second frames 432. Each step of the first support frame 411 is connected to a plurality of first frames 431, and each step of the second support frame 421 is connected to a plurality of second frames 432. In the same step of the first support frame 411, the first frames 431 are arranged horizontally at intervals, and in the same step of the second support frame 421, the second frames 432 are arranged horizontally at intervals. In the corresponding steps of the first support frame 411 and the second support frame 421, the first frames 431 and the second frames 432 are flush. At the same time, one end of the first frame 431 and the second frame 432 are respectively connected to the corresponding first support frame 411 and the second support frame 421 by bolts, and the other ends of the first frame 431 and the second frame 432 are staggered and overlapped in sequence and connected by embedded components 433, so that the first frame 431 and the second frame 432 can slide in the extension direction.

[0094] The top surfaces of the first support frame 411 and the second support frame 421 of this embodiment are stepped from both sides to the middle, so that the corridor bridge has multiple working surfaces of different heights, which facilitates operators to stand on different working surfaces to operate. Moreover, this distribution method is compatible with large-diameter cylindrical riveted parts and is suitable for assembling large-diameter cylindrical riveted parts. At the same time, the first support frame 411 and the second support frame 421 of this embodiment are directly placed on the first suspension frame 41 and the second suspension frame 42, so that the mounting block 414 contacts the support block 412 and the clamping groove 415 cooperates with the clamping block 413. No additional fixing is required, which reduces the difficulty of assembling and disassembling the corridor bridge, reduces the assembly and disassembly time, and improves the assembly and disassembly efficiency.

[0095] Both sides of the first and second profiles 431, 432 are provided with insertion slots 434, extending in the same direction as the first and second profiles 431, 432. Insertion members 433 extend into the insertion slots 434 of the adjacent first and second profiles 431, 432, respectively. These insertion members 433 serve not only to connect the first and second profiles 431, 432 but also to guide the sliding movement between them.

[0096] To ensure good connectivity between the embedded component 433 and the first and second frames 431 and 432, in this embodiment, the embedded grooves 434 are T-shaped, so that the cross-sections of the first and second frames 431 and 432 are I-shaped. In this case, the cross-sections of both sides of the embedded component 433 are T-shaped. In other embodiments of the present invention, the embedded grooves 434 may be provided on all four sides of the first and second frames 431 and 432.

[0097] In order to prevent the embedded component 433 from being separated from the first frame 431 or the second frame 432 due to uncertain movement, thereby causing the adjacent first frame 431 and the second frame 432 to separate, in this embodiment, between the adjacent first frame 431 and the second frame 432, the embedded component 433 is fixedly connected to one of the frames by a hexagon socket screw, and the embedded component 433 slides with the other frame. At this time, within the set length variation range, the embedded component 433 will not be separated from the first frame 431 or the second frame 432.

[0098] In this embodiment, anti-sinking plates (not shown) are laid on the first and second frames 431 and 432 on the steps corresponding to the first support frame 411 and the second support frame 421 to prevent operators from falling into the gap. The size of the anti-sinking plates is adapted to the length of the corridor during operation.

[0099] In this embodiment, the first support frame 411 and the second support frame 421 are directly placed on the first suspension frame 41 and the second suspension frame 42, so that the mounting block 414 contacts the support block 412 and the card slot 415 cooperates with the card block 413. No additional fixation (such as bolt fixation, etc.) is required, which reduces the assembly difficulty of the corridor bridge, reduces the assembly time, and improves the assembly efficiency.

[0100] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
