Among them, the bottom and web of the box girder refer to the bottom plate and web in the box girder structure, which are important components of the box girder and play a key role in structural force and load transfer. Among them, the bottom plate is located at the bottom of the box girder and is the horizontal part of the box girder cross-section, used to bear the vertical load of the bridge structure and transfer the load to the piers or abutments. The web is a vertical or inclined plate connecting the top plate and the bottom plate of the box girder, located on the side of the box girder, and its main function is to resist shear force, bear the lateral load transmitted from the bridge deck, and transfer it to the bottom plate and piers.

The buffer rack 11 is horizontally arranged left and right; the bottom progressive conveying mechanism 12 includes a driving assembly 122 and a transmission assembly 121; the transmission assembly 121 is arranged on the buffer rack 11 and two are arranged at intervals left and right; the driving assembly 122 is arranged inside the buffer rack 11 and is in transmission connection with the transmission assembly 121; there are two side progressive conveying mechanisms 13, including a conveying rack 131, a lower progressive conveying component 132, and an upper progressive conveying component 133; the conveying rack 131 is vertically arranged, and the two conveying racks 131 of the two side progressive conveying mechanisms 13 are respectively arranged on the front and rear sides of the middle part of the top surface of the buffer rack 11; the lower progressive conveying component 132 is arranged on the upper part of one side of the conveying rack 131 facing the left and right midline of the buffer rack 11; the upper progressive conveying component 133 is arranged on the top surface of the conveying rack 131; the guiding mechanism 14 is arranged on the front and rear sides of the top surface of the buffer rack 11, including a guiding rack 141, a lower guiding component 142, and an upper guiding component 143; the guiding rack 141 is vertically arranged; the lower guiding component 142 is arranged on one side of the guiding rack 141 facing the center of the buffer rack 11 and is connected to the lower progressive conveying component 132; the upper guiding component 143 is arranged on the top surface of the guiding rack 141 and is connected to the upper progressive conveying component 133; after the bottom and web steel bar mesh of the box girder is sequentially sent to the loading position on the left side of the buffer rack 11, the lower progressive conveying component 132 and the upper progressive conveying component of the side progressive conveying mechanism 13 alternately cooperate with the bottom progressive conveying mechanism 12 to convey the mesh.

[0054] As Figure 2-4As shown in the figure, the bottom progressive conveying mechanism 12 includes a transmission assembly 121 and a drive assembly 122. There are two transmission assemblies 121, which are arranged front and rear on the buffer rack 11 respectively, and include transmission sprockets 1211 and conveying chains 1212. There are two transmission sprockets 1211, which are respectively rotatably arranged at the left and right ends of the buffer rack 11. The conveying chain 1212 is wound around the transmission sprocket 1211, and the conveying chain 1212 can move on the transmission sprocket 1211 and the buffer rack 11. The drive assembly 122 includes a drive motor 1221, a drive shaft 1222, a bearing seat 1223, and a drive sprocket 1224. The drive motor 1221 is fixedly arranged at the rear part on the left side inside the buffer rack 11, and its output shaft faces forward. The drive motor 1221 is a stepping motor. The bearing seat 1223 is arranged inside the buffer rack 11, in front of the drive motor 1221, and two are arranged at intervals in the front and rear directions. One end of the drive shaft 1222 is fixedly connected to the output shaft of the drive motor 1221, and the other end is rotatably connected to the two bearing seats 1223. The drive sprocket 1224 is sleeved on the drive shaft 1222, and there are two corresponding to the conveying chain 1212. The two drive sprockets 1224 are respectively meshed with the two conveying chains 1212. The drive motor 1221 drives the drive shaft 1222 to rotate on the bearing seat 1223, drives the drive sprocket 1224 to rotate, and the drive sprocket 1224 drives the conveying chain 1212 to move on the buffer rack 11 and the transmission sprocket 1211. When the mesh is sent to the buffer rack 11, the stirrups at the bottom of the mesh are placed on the conveying chain 1212. Since the drive motor 1221 is a stepping motor, it drives the conveying chain 1212 to move a step distance each time, realizing the progressive conveying of the bottom of the mesh.

[0055] As Figure 6-9As shown in the figure, the side progressive conveying mechanism 13 includes a conveying frame 131, a lower progressive conveying component 132, and an upper progressive conveying component 133. The conveying frame 131 is vertically arranged, and the two buffer racks 11 of the two side conveying mechanisms are respectively arranged on the front and rear sides of the middle part of the top surface of the buffer rack 11. The lower progressive conveying component 132 includes a lower progressive mounting plate 1321, a lower conveying cylinder 1322, a lower connecting block 1324, a lower connecting plate 1323, a lower clamping cylinder 1325, and a lower progressive comb plate 1326. The lower progressive mounting plate 1321 is horizontally arranged on the upper part of one side of the conveying frame 131 facing the left and right midline of the buffer rack 11. The lower conveying cylinder 1322 is horizontally arranged on the lower progressive mounting plate 1321, and its piston rod faces left. The lower connecting plate 1323 is horizontally arranged left and right, and its rear side is fixedly connected to the lower conveying cylinder 1322 through the lower connecting block 1324. The lower clamping cylinder 1325 is horizontally arranged on the connecting plate, and a plurality of them are arranged at intervals left and right, and its piston rod faces the center direction of the buffer rack 11. The lower progressive comb plate 1326 has an L-shaped structure, its vertical side is fixedly connected to the piston rod of the lower clamping cylinder 1325, the horizontal side faces the center direction of the buffer rack 11, and its comb teeth are located on the horizontal side.

[0056] The upper progressive conveying component 133 includes an upper progressive mounting plate 1331, an upper conveying cylinder 1332, an upper connecting block 1333, an upper connecting plate 1334, an upper clamping cylinder 1335, and an upper progressive comb plate 1336. The upper progressive mounting plate 1331 is horizontally arranged on the top surface of the conveying frame 131. The upper conveying cylinder 1332 is horizontally arranged on the upper progressive mounting plate 1331, and its piston rod faces left. The upper connecting plate 1334 is horizontally arranged left and right, and its rear side is fixedly connected to the upper conveying cylinder 1332 through the upper connecting block 1333. The upper clamping cylinder 1335 is horizontally arranged on the connecting plate, and a plurality of them are arranged at intervals left and right, and its piston rod faces the center direction of the buffer rack 11. The upper progressive comb plate 1336 has an L-shaped structure, its vertical side is fixedly connected to the piston rod of the upper clamping cylinder 1335, the horizontal side faces the center direction of the buffer rack 11, and its comb teeth are located on the horizontal side.

[0057] The distance between the upper progressive conveying component 133 and the left and right midline of the buffer rack 11 in the horizontal direction is greater than the distance between the lower progressive conveying component 132 and the left and right midline of the buffer rack 11 in the horizontal direction, so that an inclination is formed between the upper progressive conveying component 133 and the lower progressive conveying component 132 towards the buffer rack 11, so that the progressive comb plates of the upper progressive conveying component 133 and the lower progressive conveying component 132 are adapted to the inclination angle of the side stirrups of the mesh sheet, and the comb plates can be ensured to firmly hold the mesh sheet.

[0058] When the first mesh sheet is sent to the buffer rack 11, the lower progressive conveying components 132 of the two side progressive conveying mechanisms 13 are activated. The piston rods of multiple lower clamping cylinders 1325 extend, driving the lower progressive comb plates 1326 to move towards the mesh sheet, clamping the stirrups on both sides of the mesh sheet. The drive motor 1221 of the bottom progressive conveying mechanism 12 is activated, causing the conveying chain 1212 to move leftward by one pitch. At the same time, the piston rod of the lower conveying cylinder 1322 extends by a stroke of one pitch, driving the lower connecting plate 1323 and the lower progressive comb plate 1326 to move leftward by a stroke of one pitch, thereby cooperating with the bottom progressive conveying mechanism 12 to convey the mesh sheet leftward by a stroke of one pitch. At this time, since the lower connecting plate 1323 and the lower progressive comb plate 1326 of the lower progressive conveying component 132 have moved forward by one pitch, the lower connecting plate 1323 and the lower progressive comb plate 1326 are staggered from the upper connecting plate 1334 and the upper progressive comb plate 1336 by one pitch, enabling the second mesh sheet to be loaded into the upper progressive conveying component 133. After the movement is completed, the second mesh sheet is loaded between the upper progressive comb plates 1336 of the upper progressive conveying component 133. The piston rods of multiple upper clamping cylinders 1335 extend, driving the upper progressive comb plates 1336 to move downward towards the mesh sheet, clamping the stirrups on both sides of the second mesh sheet and clamping the first mesh sheet at the same time. At this time, the piston rods of the lower clamping cylinders 1325 of the lower progressive conveying component 132 retract, causing the lower progressive comb plates 1326 to reset. At the same time, the piston rod of the lower conveying cylinder 1322 retracts, causing the lower progressive conveying component 132 to reset. After the lower progressive conveying component 132 resets, the bottom progressive conveying mechanism 12 continues to move the conveying chain 1212 leftward by one pitch. The upper progressive conveying component 133, in the same working mode as the lower progressive conveying component 132, cooperates with the bottom progressive conveying mechanism 12 to convey the mesh sheet leftward by one pitch. The lower progressive conveying component 132 and the upper progressive conveying component 133 respectively cooperate with the bottom progressive conveying mechanism 12 to perform alternating feeding and progressive conveying of the mesh sheet, thereby conveying the mesh sheet sent by the feeding device 2 to the unloading position of the buffer rack 11.

[0059] As Figure 10-11As shown in the figure, the cache device 1 further includes a guiding mechanism 14. The guiding mechanism 14 is arranged on the front and rear sides of the top surface of the cache rack 11, and a plurality of guiding mechanisms 14 are arranged at intervals left and right on each side. The guiding mechanism 14 includes a guiding frame 141, a lower guiding component 142, and an upper guiding component 143. The guiding frame 141 is arranged vertically. The lower guiding component 142 includes a lower guiding mounting plate 1421, a lower guiding member 1422, a lower guiding wheel 1423, and a lower sliding wheel 1424. The lower guiding mounting plate 1421 is arranged horizontally on the side of the guiding frame 141 facing the center of the cache rack 11. The lower guiding member 1422 is fixedly arranged on the lower guiding mounting plate 1421, and its left and right sides are penetrated and sleeved on the lower connecting plate 1323. The lower guiding wheel 1423 is horizontally rotatably arranged on the front and rear sides of one end of the lower guiding member 1422 and is respectively in contact with the front and rear sides of the lower connecting plate 1323. The lower sliding wheel 1424 is vertically rotatably arranged on the front and rear sides of the lower connecting plate 1323, and its bottom surface is in contact with the inner bottom of the lower guiding member 1422.

[0060] The upper guiding component 143 includes an upper guiding mounting plate 1431, an upper guiding member 1432, an upper guiding wheel 1433, and an upper sliding wheel 1434. The upper guiding mounting plate 1431 is arranged horizontally on the top surface of the guiding frame 141. The upper guiding member 1432 is fixedly arranged on the upper guiding mounting plate 1431, and its left and right sides are penetrated and sleeved on the upper connecting plate 1334. The upper guiding wheel 1433 is horizontally rotatably arranged on the front and rear sides of one end of the upper guiding member 1432 and is respectively in contact with the front and rear sides of the upper connecting plate 1334. The upper sliding wheel 1434 is vertically rotatably arranged on the front and rear sides of the upper connecting plate 1334, and its bottom surface is in contact with the inner bottom of the upper guiding member 1432.

[0061] When the lower connecting plate 1323 of the lower-level incoming conveying component 132 and the upper connecting plate 1334 of the upper-level incoming conveying move, the upper guiding component and the lower guiding component 142 play a supporting role for the connecting plate through the sliding wheels, and ensure the moving stability of the connecting plate through the guiding wheels.

[0062] As Figure 10-11As shown in the figure, the side progressive conveying mechanism 13 further includes a lower sliding assembly 15 and an upper sliding assembly 16; the lower sliding assembly 15 includes a lower slide rail 151 and a lower slider 152; the lower slide rail 151 is horizontally arranged front and rear on the top surface of the lower connecting plate 1323, and a plurality of them are arranged at intervals left and right; the lower end of the lower slider 152 is slidably connected to the lower slide rail 151, and the top end is fixedly connected to the bottom surface of the lower progressive comb plate 1326; the upper sliding assembly 16 includes an upper slide rail 161 and an upper slider 162; the upper slide rail 161 is horizontally arranged front and rear on the top surface of the upper connecting plate 1334, and a plurality of them are arranged at intervals left and right; the upper end of the upper slider 162 is slidably connected to the upper slide rail 161, and the top end is fixedly connected to the bottom surface of the upper progressive comb plate 1336. The lower sliding assembly 15 and the upper sliding assembly 16 can ensure the stability of the lower progressive comb plate 1326 and the upper progressive comb plate 1336 during forward and backward movement.

[0063] As Figure 5 shown in the figure, the bottom progressive conveying mechanism 12 further includes a tensioning assembly 123; two tensioning assemblies 123 are provided corresponding to each transmission assembly 121, and the two tensioning assemblies 123 corresponding to each transmission assembly 121 are arranged at intervals left and right on both sides of the driving assembly 122. The tensioning assembly 123 includes a tensioning mounting plate 1231 and a tensioning wheel 1232; the tensioning mounting plate 1231 is vertically arranged in the buffer rack 11, and two of them are arranged at intervals left and right; the tensioning wheel 1232 is vertically rotatably arranged in the two tensioning mounting plates 1231 and meshes with the driving chain. The conveying chain 1212 winds from the bottom of the left driving sprocket 1211 to the upper part of the tensioning wheel 1232 of the left tensioning assembly 123, then winds around the bottom of the driving sprocket 1224, and finally leads out from the upper part of the right tensioning wheel 1232 to the right driving sprocket 1211, thereby adjusting the tension of the chain.

[0064] As Figure 12-15As shown in the figure, it further includes a feeding device 2. The feeding device 2 is located on the left and right sides of the buffer device 1. The feeding device 2 on the right side of the buffer device 1 is used to load the mesh sheet into the buffer device 1, and the feeding device 2 on the left side of the buffer device 1 is used to unload the mesh sheet from the buffer device 1. The feeding device 2 includes a feeding frame 21 and a clamping component 22. The feeding frame 21 includes a horizontal rod 211, a vertical rod 212, and a robot connecting plate 213. The horizontal rod 211 is horizontally arranged left and right, and two are arranged at intervals up and down. The vertical rod 212 is vertically arranged between the two horizontal rods 211, and two are arranged at intervals front and back. The robot connecting plate 213 is vertically arranged between the two vertical rods 212 and is fixedly connected to the two horizontal rods 211. The robot connecting plate 213 is used to connect the robotic arm. Four clamping components 22 are provided, which are respectively arranged on the front and back sides of the top surfaces of the two horizontal rods 211. The clamping components 22 on the front and back sides of the two horizontal rods 211 form an inclined angle adapted to the side stirrups of the mesh sheet.

[0065] The clamping component 22 includes a clamping fixed seat 221, a clamping mounting seat 222, a clamping cylinder 223, a clamping plate 224, and a limiting plate 225. The clamping fixed seat 221 is an L-shaped structure, its horizontal side is connected to the horizontal rod 211, and its vertical side is located on the top surface of the right side of the horizontal side. The clamping mounting seat 222 is inclined and arranged on the clamping fixed seat 221. One side of it is connected to the horizontal side of the clamping fixed seat 221, and the other side is connected to the vertical side of the clamping fixed seat 221. The clamping cylinder 223 is arranged on the clamping fixed seat 221. The clamping cylinder 223 is a finger cylinder, and its fingers face left. The clamping plate 224 is arranged on the two fingers of the clamping cylinder 223. A clamping opening is provided on the opposite side of the two clamping plates 224. The limiting plate 225 is arranged on the top surface of the clamping cylinder 223, and a notch is opened on its left side. When loading the mesh sheet onto the buffer device 1, the robotic arm drives the feeding device 2 close to the mesh sheet, makes the side stirrups of the mesh sheet enter the limiting plate 225, and then clamps the side stirrups of the mesh sheet through the clamping cylinder 223 and the clamping plate 224. After clamping, the robotic arm drives the feeding device 2 to move towards the buffer device 1, and the clamping plate 224 is opened through the clamping cylinder 223, thereby placing the mesh sheet on the buffer device 1. When unloading the mesh sheet from the buffer device 1, the mesh sheet is clamped and taken out in the same way as above, and then it can be unloaded.

[0066] In a further embodiment, the horizontal rod 211 is an aluminum profile with grooves. The clamping fixed seat 221 is connected to the grooves of the horizontal rod 211 through bolts, so that the clamping component 22 can be adjusted in position on the horizontal rod 211, which is convenient for adjusting the position of the clamping component 22 according to the mesh sheet specifications, and improves flexibility and adaptability.

[0067] The clamping cylinder 223 is slidably connected to the clamping mounting seat 222 through a slide rail and a slide table; it further includes an absorption spring 23 and a spring mounting seat 24; the spring mounting seat 24 is arranged on the right side of the top surface of the clamping fixed seat 221; one end of the absorption spring 23 is fixedly connected to the spring mounting seat 24, and the other end is fixedly connected to the right end of the clamping cylinder 223. When the mesh is stuck between the lower comb plate and the upper comb plate on the buffer rack 11, the comb plate cannot be closely attached to the side stirrups, and there will be a certain front-back inclination, resulting in a position deviation between multiple inclined meshes. The elastic deformation of the absorption spring 23 compensates for the horizontal displacement difference of the clamping cylinder 223 to ensure that each mesh can be accurately clamped and conveyed.

[0068] In a further embodiment, it further includes a proximity switch 25; the proximity switch 25 is fixedly arranged on the top surface of the limit plate 225, and the clamping cylinder 223 is controlled by the proximity switch 25 to improve the intelligent level of the feeding device 2.

[0069] The working mode of the present invention is as follows:

[0070] When loading the mesh onto the buffer device 1, the feeding device 2 located on the right side of the buffer device 1 drives the feeding device 2 close to the mesh through the robotic arm connected thereto, and makes the side stirrups of the mesh enter the limit plate 225. Then, the side stirrups of the mesh are clamped by the clamping cylinder 223 and the clamping plate 224. After clamping, the robotic arm drives the feeding device 2 to move towards the buffer device 1, and the clamping plate 224 is opened by the clamping cylinder 223, thereby placing the mesh on the buffer device 1.

[0071] When the feeding device 2 sends the first mesh sheet to the buffer rack 11, the lower progressive conveying assemblies 132 of the two side progressive conveying mechanisms 13 are activated. The piston rods of multiple lower clamping cylinders 1325 extend, driving the lower progressive comb plates 1326 to move towards the mesh sheet, clamping the stirrups on both sides of the mesh sheet. The drive motor 1221 of the bottom progressive conveying mechanism 12 is activated, causing the conveying chain 1212 to move leftward by one pitch. At the same time, the piston rod of the lower conveying cylinder 1322 extends by a stroke of one pitch, driving the lower connecting plate 1323 and the lower progressive comb plate 1326 to move leftward by a stroke of one pitch, thereby cooperating with the bottom progressive conveying mechanism 12 to convey the mesh sheet leftward by a stroke of one pitch. At this time, since the lower connecting plate 1323 and the lower progressive comb plate 1326 of the lower progressive conveying assembly 132 have moved forward by one pitch, the connecting plate and the lower progressive comb plate 1326 are staggered from the upper connecting plate 1334 and the upper progressive comb plate 1336 by one pitch, enabling the second mesh sheet to be loaded into the upper progressive conveying assembly 133. After the movement is completed, the second mesh sheet is loaded between the upper progressive comb plates 1336 of the upper progressive conveying assembly 133. The piston rods of multiple upper clamping cylinders 1335 extend, driving the upper progressive comb plates 1336 to move downward towards the mesh sheet, clamping the stirrups on both sides of the second mesh sheet and clamping the first mesh sheet at the same time. At this time, the piston rods of the lower clamping cylinders 1325 of the lower progressive conveying assembly 132 retract, causing the lower progressive comb plates 1326 to reset. At the same time, the piston rods of the lower conveying cylinders 1322 retract, causing the lower progressive conveying assembly 132 to reset. After the lower progressive conveying assembly 132 resets, the bottom progressive conveying mechanism 12 continues to move the conveying chain 1212 leftward by one pitch. The upper progressive conveying assembly 133, in the same working mode as the lower progressive conveying assembly 132, cooperates with the bottom progressive conveying mechanism 12 to convey the mesh sheet leftward by one pitch. The lower progressive conveying assembly 132 and the upper progressive conveying assembly 133 respectively cooperate with the bottom progressive conveying mechanism 12 to perform alternating feeding and progressive conveying of the mesh sheet, thereby conveying the mesh sheet sent by the feeding device 2 to the unloading position of the buffer rack 11, and finally unloading the mesh sheet through the feeding device 2 located on the left side of the buffer device 1.

[0072] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
