DETAILED DESCRIPTION

[0022] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0023] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0024] like Figure 1 , Figure 5As shown, it is a structural diagram of an automatic cable laying device for a bridge provided by an embodiment of the present invention, comprising a fixed frame 1, the fixed frame 1 is a rectangular ring structure, a vertical plate 4 is fixedly installed in the middle of the fixed frame 1, a cable reel 3 is arranged above the fixed frame 1, and a cable 31 is rolled up on the surface of the cable reel 3, two groups of pressing rollers 32 which are respectively located on both sides of the vertical plate 4 and cooperate with the cable 31 are rotatably installed in the inner cavity of the fixed frame 1, a traveling component 2 is arranged on the front and rear sides of the fixed frame 1, and the traveling component 2 is used to control the movement of the fixed frame 1 in the bridge, a tape mechanism 5 which cooperates with the cable 31 is arranged on the surface of the vertical plate 4, and the tape mechanism 5 includes a tape reel 51, a positioning component 52 and a reeling component 53, the tape reel 51 has a tape rolled up on the surface, and the positioning component 52 is located on the side wall of the vertical plate 4 It is also connected to the tape roll 51. The positioning component 52 is used to support and position the tape roll 51 on the surface of the vertical plate 4. The unwinding component 53 is located on the side wall of the vertical plate 4 and is connected to the positioning component 52. The unwinding component 53 pulls the tape to move above the cable 31 by cooperating with the positioning component 52. The surface of the vertical plate 4 is provided with a pasting mechanism 6 that cooperates with the tape. The pasting mechanism 6 includes a cutting component 61 and a control component 62. The cutting component 61 is located on the side wall of the vertical plate 4 and is above the tape. The control component 62 is located on the side wall of the vertical plate 4 and is connected to the cutting component 61. When the tape stops moving above the cable 31, the control component 62 cuts the tape by cooperating with the cutting component 61 and puts the cut tape on the outside of the cable 31 and compacts it on the inner wall of the bridge.

[0025] When in use, the cable reel 3 is installed on the fixing frame 1, the fixing frame 1 is placed in the bridge, the cable 31 is pulled out from the surface of the cable reel 3, passed under the two sets of wire pressing rollers 32 and fixed to the end of the bridge, the positioning component 52 positions and installs the tape reel 51 on the front of the vertical plate 4, and allows the tape to pass over the cable 31, the traveling component 2 controls the fixing frame 1 to move in the bridge, while the fixing frame 1 moves, the cable reel 3 rotates to unwind the cable 31 into the inner cavity of the bridge, when the cable 31 is unwound and installed, the unwinding 53 cooperates with the positioning component 52, The tape can be pulled at equal intervals to move a certain distance above the cable 31. When the tape stops moving, the control component 62 cooperates with the splitting component 61 to cut the tape directly above the cable 31 from top to bottom, and the cut strip of tape is covered on the surface of the cable 31. The strip of tape is pressed and the tape is pasted on the inner wall of the bridge. After a single cut and press, the splitting component 61 is released from the cutting state, and the unwinding component 53 cooperates with the positioning component 52 to control the tape to move a certain distance again. After the tape moves a certain distance, it can be cut and pressed again. Repeat this process many times. While laying the cable 31 in the bridge, the tape can be pasted and positioned in the inner cavity of the bridge, which effectively improves the stability of the laid cable 31, avoids the cables 31 from being laid randomly in the inner cavity of the bridge, and saves the amount of laid cables 31.

[0026] like Figure 1 , Figure 2 , Figure 3 As shown, as a preferred embodiment of the present invention, the traveling component 2 includes a load-bearing rod 21 rotatably installed at the front and rear ends of the fixed frame 1, both ends of the load-bearing rod 21 extend to the outside of the fixed frame 1 and are respectively fixedly installed with rollers 22, and a dual-axis motor 23 is fixedly installed at the end of the fixed frame 1, and the output shaft of the dual-axis motor 23 is connected to the load-bearing rod 21.

[0027] After the fixing frame 1 is placed in the inner cavity of the bridge frame, the dual-axis motor 23 drives the bearing rod 21 to rotate and then drives the roller 22 to rotate. The multiple groups of rollers 22 at the front and rear ends of the fixing frame 1 cooperate with each other, which can conveniently control the movement of the fixing frame 1 in the inner cavity of the bridge frame.

[0028] like Figure 1 , Figure 3 , Figure 4As shown, as a preferred embodiment of the present invention, the positioning assembly 52 includes a first supporting column 521 rotatably installed on the front side of the vertical plate 4, the tape roll 51 is installed on the surface of the first supporting column 521, the second supporting column 523 is rotatably installed on the front side of the vertical plate 4, a winding disk 524 is installed on the surface of the second supporting column 523, two groups of relatively distributed guide rollers 522 are rotatably installed on the bottom of the front side of the vertical plate 4, and the tape on the surface of the tape roll 51 passes through the two groups of guide rollers 522 and is connected to the winding disk 524.

[0029] The tape roll 51 is mounted on the surface of the first bearing column 521, and the reel 524 is mounted on the surface of the second bearing column 523. The tape is pulled out from the surface of the tape roll 51, and the tape is further passed under the two sets of guide rollers 522 so that the tape is connected to the reel 524. When the fixed frame 1 moves in the inner cavity of the bridge frame to lay the cable 31, the unwinding assembly 53 controls the second bearing column 523 to rotate a certain angle at equal intervals, and the second bearing column 523 drives the reel 524 to rotate a certain angle synchronously. The reel 524 rewinds the tape while rotating, and then pulls the tape to move above the cable 31. When the tape stops moving, the cutting assembly 61 squeezes and cuts the tape between the two sets of guide rollers 522.

[0030] like Figure 2 , Figure 4 , Figure 5 As shown, as a preferred embodiment of the present invention, the unwinding assembly 53 includes a second supporting column 523, one end of which is extended away from the winding disk 524 to the back of the vertical plate 4 and is fixedly installed with a fixed toothed disk 531, a horizontal column 532 is rotatably installed on the back of the vertical plate 4, a transmission disk 533 is fixedly installed on the surface of the horizontal column 532, and an arc-shaped rack 534 is provided on the side wall of the transmission disk 533, and the rack 534 is meshed with the fixed toothed disk 531, a motor 535 is fixedly installed on the back of the vertical plate 4, and a synchronous disk 536 is fixedly installed on the output shaft of the motor 535 and the surface of the horizontal column 532, and a synchronous belt 537 is commonly installed on the surface of the two sets of synchronous disks 536.

[0031] When in use, the motor 535 drives the synchronous disk 536 to rotate, and the two sets of synchronous disks 536 cooperate with the synchronous belt 537 to drive the horizontal column 532 to rotate. The horizontal column 532 drives the transmission disk 533 to rotate on the back of the vertical plate 4, and the transmission disk 533 drives the rack 534 to rotate synchronously. When the rack 534 contacts the fixed toothed disk 531 for meshing transmission, the rack 534 drives the fixed toothed disk 531 to rotate and then drives the second bearing column 523 to rotate synchronously. When the rack 534 and the fixed toothed disk 531 are separated from each other, the fixed toothed disk 531 stops rotating, and the fixed toothed disk 531 drives the second bearing column 523 to stop rotating synchronously.

[0032] like Figure 1, Figure 3 , Figure 4 , Figure 6 As shown, as a preferred embodiment of the present invention, the splitting assembly 62 includes a supporting plate 611 arranged on the outside of the vertical plate 4, and a ring-shaped cutting blade 612 is fixedly installed on the bottom wall of the supporting plate 611. Two groups of extrusion springs 613 located in the inner cavity of the cutting blade 612 and relatively distributed are fixedly installed on the bottom wall of the supporting plate 611, and the telescopic end of the extrusion spring 613 extends to the outside of the cutting blade 612 and a compaction pad 614 is fixedly installed thereon, and a cutting edge 615 that cooperates with the cable 31 is arranged in the middle of the cutting blade 612.

[0033] The carrier plate 611 positions the cutting blade 612 and the compacting pad 614. Initially, the cutting blade 612 and the compacting pad 614 are above the tape. When the tape stops moving, the control component 62 drives the carrier plate 611 to move vertically downward for a certain distance. The carrier plate 611 drives the cutting blade 612 and the compacting pad 614 to move downward synchronously. The cutting blade 612 and the cutting edge 615 cooperate with each other to automatically cut the tape above the cable 31 between the two sets of guide rollers 522. After cutting, the extrusion spring 613 and the compacting pad 614 are pressed together. 614 cooperate with each other to press the cut tape on both sides of the cable 31. The cut tape is put on the outside of the cable 31 and adhered to the inner wall of the bridge. The tape can fix the position of the cable 31 in the inner cavity of the bridge. After a single cut, the control component 62 drives the supporting plate 611 to move upward to its original position, and the supporting plate 611 drives the cutting blade 612 and the compacting pad 614 to move upward synchronously. At this time, the winding reel 524 rotates to rewind the tape, which can pull the tape to move a certain distance, so as to facilitate cutting the tape again above the cable 31.

[0034] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, as a preferred embodiment of the present invention, the control component 62 includes a rotating column 621 rotatably installed on the surface of the vertical plate 4, one end of the rotating column 621 extends to the front of the vertical plate 4 and is fixedly installed with a control disk 622, and a lifting plate 623 located on the outside of the control disk 622 is slidably installed on the front of the vertical plate 4 along the vertical direction, and a limiting groove 624 is provided on the surface of the lifting plate 623, and a limiting column 625 inserted into the limiting groove 624 is provided at a position deviating from the center of the control disk 622. A vertical cylinder 626 is fixedly installed on the bottom wall of the lifting plate 623, and the bearing plate 611 is arranged at the bottom end of the vertical cylinder 626. One end of the rotating column 621 away from the control disk 622 extends to the back of the vertical plate 4 and is fixedly installed with a control toothed disk 627, and the control toothed disk 627 is meshed with the rack 534.

[0035] The transmission disk 533 drives the rack 534 to rotate. When the rack 534 contacts the control toothed disk 627, the rack 534 and the control toothed disk 627 are meshed and transmitted to drive the rotating column 621 to rotate. The rotating column 621 drives the control disk 622 to rotate synchronously on the front of the vertical plate 4. The control disk 622 drives the limiting column 625 to rotate synchronously. The limiting column 625 cooperates with the limiting groove 624 to control the lifting plate 623 to reciprocate in the vertical direction outside the control disk 622. The lifting plate 623 drives the vertical cylinder 626 and the bearing plate 611 to reciprocate synchronously in the vertical direction. When the bearing plate 611 moves downward, the cutting blade 612 can cut the tape. After cutting, the bearing plate 611 drives the cutting blade 612 to move upward. At this time, the rack 534 and the control toothed disk 627 are separated from each other, and the control toothed disk 627 stops rotating, thereby driving the control disk 622 to stop rotating. At this time, the bearing plate 611 stops moving in place.

[0036] like Figure 6 As shown, as a preferred embodiment of the present invention, a vertical rod 7 is fixedly installed on the top wall of the bearing plate 611, and the vertical rod 7 is slidably installed in the vertical tube 626. A telescopic spring 8 connected to the vertical rod 7 is fixedly installed in the vertical tube 626.

[0037] When the lifting plate 623 drives the vertical cylinder 626 to move downward, the vertical cylinder 626 drives the supporting plate 611, the cutting blade 612 and the compacting pad 614 to move downward synchronously. The cutting blade 612 cuts the tape and contacts the inner wall of the bridge frame. The vertical rod 7 moves in the inner cavity of the vertical cylinder 626, and the relative position of the supporting plate 611 and the vertical cylinder 626 can be easily adjusted, so as to protect the cutting blade 612 from impact.

[0038] like Figure 3 As shown, as a preferred embodiment of the present invention, a rubber pad 9 is provided on the surface of the roller 22. The rubber pad 9 can effectively increase the friction resistance between the roller 22 and the inner wall of the bridge, and effectively improve the stability of the fixing frame 1 when it moves in the inner cavity of the bridge.

[0039] The working principle of the present invention is: when in use, the cable reel 3 is installed on the fixed frame 1, the fixed frame 1 is placed in the bridge frame, the cable 31 is pulled out from the surface of the cable reel 3, passes under the two sets of crimping rollers 32 and is fixed at the end of the bridge frame, the tape reel 51 is installed on the surface of the first bearing column 521, the reel 524 is installed on the surface of the second bearing column 523, the tape is pulled out from the surface of the tape reel 51, and the tape is further passed under the two sets of guide rollers 522 so that the tape is connected to the reel 524. The dual-axis motor 23 drives the bearing rod 21 to rotate and then drives the roller 22 to rotate. The multiple sets of rollers 22 at the front and rear ends of the fixed frame 1 cooperate with each other, and the fixed frame 1 can be conveniently controlled to move in the inner cavity of the bridge frame. While the fixed frame 1 is moving, the cable reel 3 rotates and unwinds the cable 31 into the inner cavity of the bridge frame.

[0040] When the cable 31 is unwound and installed, the motor 535 drives the synchronous disk 536 to rotate, and the two sets of synchronous disks 536 cooperate with the synchronous belt 537 to drive the horizontal column 532 to rotate, and the horizontal column 532 drives the transmission disk 533 to rotate on the back of the vertical plate 4, and the transmission disk 533 drives the rack 534 to rotate synchronously. When the rack 534 contacts the fixed toothed disk 531 for meshing transmission, the rack 534 drives the fixed toothed disk 531 to rotate and then drives the second bearing column 523 to rotate synchronously, and the second bearing column 523 rotates synchronously. 23 drives the winding disk 524 to rotate synchronously at a certain angle. The winding disk 524 reels the tape while rotating, thereby pulling the tape to move above the cable 31. When the tape stops moving, the rack 534 engages with the control toothed disk 627 to drive the rotating column 621 to rotate. The rotating column 621 drives the control disk 622 to rotate synchronously on the front of the vertical plate 4. The control disk 622 drives the limiting column 625 to rotate synchronously. The limiting column 625 cooperates with the limiting slot 624 to control the lifting plate 623 to rotate in the control position. The outer side of the control plate 622 reciprocates in the vertical direction, and the lifting plate 623 drives the vertical cylinder 626 and the carrying plate 611 to reciprocate synchronously in the vertical direction. When the carrying plate 611 moves downward, it drives the cutting blade 612 and the compacting pad 614 to move downward synchronously. The cutting blade 612 and the cutting edge 615 cooperate with each other to automatically cut the tape above the cable 31 between the two sets of guide rollers 522. After cutting, the extrusion spring 613 and the compacting pad 614 cooperate with each other to automatically cut the tape above the cable 31. The cut tape is pressed on both sides of cable 31, and the cut tape is put on the outside of cable 31 and pasted on the inner wall of bridge frame. The tape can fix the position of cable 31 in the inner cavity of bridge frame. After a single cutting, the carrier plate 611 moves upward to the original position, and the carrier plate 611 drives the cutting blade 612 and the compacting pad 614 to move upward synchronously. At this time, the winding disk 524 rotates to rewind the tape, and the tape can be pulled to move a certain distance, so as to facilitate cutting the tape again above the cable 31. Repeat this for many times. While laying the cable 31 in the bridge frame, the tape can be used to stick and position the cable 31 in the inner cavity of the bridge frame, which effectively improves the stability of the laid cable 31, avoids the scattered laying of the cable 31 in the inner cavity of the bridge frame, and can save the usage of the laid cable 31.

[0041] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
