Description

Technical Field

[0001] The invention belongs to the technical field of cable laying, in particular to a subway tunnel section cable laying device. Background Art

[0002] Nowadays, when building subway tunnels, many cables need to be laid and installed in the subway tunnels. The cables are usually fixed on mounting brackets on the side walls of the tunnel. The cables need to be transmitted into the tunnel one by one and placed on the ground. The cables are then lifted and placed side by side in the mounting brackets. The cables are fixed on the mounting brackets and fixed to the side walls of the subway tunnels through numerous mounting brackets for use. The cables can be laid efficiently while protecting them from damage.

[0003] A patent with announcement number CN117013443B discloses a subway tunnel section cable laying device, including a rail cart, on which are provided a wire picking assembly, a guide assembly, a support plate and an adjustment assembly; the present invention can pick up the cables on the ground and transport them to the cable bracket through the wire picking assembly and the guide assembly, without the need for manpower to lift the cables, greatly reducing the workload and work intensity, saving time and effort, and improving the secondary processing efficiency of the ground cables, thereby improving the overall cable laying efficiency.

[0004] When the above scheme is used to lay cables in a subway tunnel, only one cable can be lifted to a fixed height and pushed into the installation bracket for installation by the staff.

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] Embodiment 1

[0032] like Figures 1 to 8As shown, a subway tunnel section cable laying device described in an embodiment of the present invention includes a transport plate 1, and a wire-releasing mechanism is provided on both sides of the transport plate 1. The wire-releasing mechanism includes a lifting device arranged on both sides of the transport plate 1, and the lifting device includes a connecting frame 12 slidably connected to one side of the transport plate 1, a second motor 13 is fixedly connected to one side of the connecting frame 12, a first threaded rod 14 is fixedly connected to the output end of the second motor 13, a lifting block 15 is slidably connected to the connecting frame 12, the first threaded rod 14 is used to drive the lifting block 15 to slide in the connecting frame 12, a groove for storing cables 37 is provided on one side of the lifting block 15, the lifting device is used to lift the cables 37, and two pushing devices are arranged between the two lifting devices, the pushing device includes multiple transmission components, and the multiple transmission components include a fourth motor 23, a connecting rod 24 is fixedly connected to the output end of the fourth motor 23, a plurality of transmission plates 25 are fixedly connected to one side of the connecting rod 24, a tilting block 39 is arranged between the two outermost connecting rods 24, and the transmission component pushes the cable 37 to move by rotating the transmission plate 25.

[0033] Specifically, when laying cables on the side walls of subway tunnels, the cables need to be fixedly installed on the mounting brackets on the side walls of the tunnels. In the present embodiment, when laying cables, the connecting frame 12 can be moved by a pushing device such as a cylinder to place the multiple cables 37 on the ground into the grooves in the lifting block 15. The second motor 13 in the lifting device is started to rotate the first threaded rod 14, so that the lifting block 15 slides in the connecting frame 12 through the rotation of the first threaded rod 14. The lifting block 15 moves with the multiple cables 37 to lift the multiple cables 37 to the side of the mounting bracket, and places the multiple cables 37 between the two transfer plates 25 on the transfer assembly. At this time, the multiple transfer plates 25 are in a "Y" shape, and the fourth motors 23 are started one by one to transfer the cables 37 on the transfer plates 25 one by one. Pass it to the outermost side, and rotate the cable 37 from the outermost transfer plate 25 to the side of the tilting block 39, continue to rotate the transfer plate 25 to make the cable 37 slide out of the transfer plate 25 and the transfer assembly along the inclined surface of the tilting block 39, and then the cable 37 can be transferred to the mounting frame through the transfer plate 25 and the tilting block 39 for subsequent installation and fixation, so that multiple cables 37 can be directly lifted to the installation height through the lifting block 15, and there is no need for workers to lift the cables 37 one by one and place them in the mounting frame; this solves the current problem of laying cables on the ground, which requires workers to lift and fix multiple cables one by one on the mounting frame, and multiple cables can be lifted together to the installation height for installation, reducing the workload of workers in laying cables and greatly improving the efficiency of cable laying.

[0034] like Figures 1 to 8As shown, the lifting device also includes a sixth motor 17 fixedly connected to one side of the transport plate 1, and the output end of the sixth motor 17 is fixedly connected to a fourth gear 30. The transport plate 1 is located on one side of the sixth motor 17 and is rotatably connected to a third threaded rod 38. One side of the third threaded rod 38 is fixedly connected to a third gear 36. The fourth gear 30 is meshedly connected to the third gear 36, and the third threaded rod 38 is threadedly connected to the connecting frame 12.

[0035] Specifically, when the cable 37 is placed on the lifting block 15, the fourth gear 30 is started to rotate the sixth motor 17 and the third threaded rod 38 is rotated. The rotation of the third threaded rod 38 causes the connecting frame 12 to move in the transport plate 1. The initial position of the connecting frame 12 is located close to the sixth motor 17 to facilitate the movement of the transport plate 1 into the tunnel. When the connecting frame 12 moves from the side close to the sixth motor 17 to the side away from the sixth motor 17, the cable 37 can be shoveled into the lifting block 15.

[0036] like Figures 1 to 8 As shown, the lifting device also includes a rotating rod 18 rotatably connected to one side of the lifting block 15 , and an arc surface 16 is provided on one side of the lifting block 15 .

[0037] Specifically, the curved surface 16 can protect the cable 37 from being damaged by hard objects when the cable 37 is shoveled into the lifting block 15, so that the cable 37 can be better moved into the lifting block 15. When the transport plate 1 is moved to lay subsequent cables 37, the cable 37 will slide on the rotating rod 18, protecting the cable 37 from being damaged by hard objects when the transport plate 1 moves.

[0038] like Figures 1 to 8 As shown, the pushing device includes two first cylinders 4 fixedly connected to one side of the transport plate 1, a connecting block 5 is fixedly connected between the output ends of the two first cylinders 4, a translation block 10 is slidably connected to one side of the connecting block 5, and the multiple transmission components also include a slider 22 slidably connected in the translation block 10, and the slider 22 is fixedly connected to the fourth motor 23.

[0039] Specifically, when the cable 37 is pushed to the mounting bracket, the first cylinder 4 is started to move the translation block 10 through the connecting block 5. The translation block 10 moves the fourth motor 23 through the slider 22 to move the transmission assembly to the installation height. At this time, the fourth motor 23 is started to place the cable 37 in the mounting bracket at a fixed height.

[0040] like Figures 1 to 8 As shown, a first motor 8 is fixedly connected to one side of the connecting block 5, a row of teeth 11 is fixedly connected to one side of the two translation blocks 10, a first gear 9 is fixedly connected to the output ends of the two first motors 8, and the two first gears 9 are meshedly connected to the row of teeth 11.

[0041] Specifically, after the cable 37 on one side is lifted, the first motor 8 is started, the first gear 9 rotates, and the translation block 10 slides in the connecting block 5 through the row of teeth 11, and the pushing device and the transmission assembly are moved to the other side of the transport plate 1, so that the cable 37 on the other side can be lifted. The side of the cable 37 that has completed the lifting work can be used for the staff to walk, move and fix the cable 37.

[0042] like Figures 1 to 8 As shown, a third motor 19 is fixedly connected to one side of the translation block 10, a bidirectional screw rod 20 is fixedly connected to the output end of the third motor 19, the bidirectional screw rod 20 is threadedly connected to a plurality of sliders 22, a smooth rod 40 is arranged in the middle of the bidirectional screw rod 20, and a push block 21 is fixedly connected to one side of the plurality of sliders 22.

[0043] Specifically, when lifting multiple cables 37, the initial position of the slider 22 is located on the smooth rod 40, and the bidirectional screw rod 20 is located on both sides of the smooth rod 40 and has two reverse threads. At this time, starting the third motor 19 to rotate the bidirectional screw rod 20 will not move the slider 22. When the pushing block 21 is pushed, the slider 22 can engage and move with the bidirectional screw rod 20. By moving multiple transmission components to the appropriate position to receive the cables 37 through the slider 22, multiple cables 37 can be lifted and pushed one by one onto the mounting frame.

[0044] like Figures 1 to 8 As shown, the transmission assembly also includes an extension plate 26 slidably connected to one side of the transmission plate 25, and a second threaded rod 27 is rotatably connected to one side of the extension plate 26. The second threaded rod 27 is threadedly connected to the transmission plate 25, and a chuck 28 is fixed to one side of the second threaded rod 27, and the chuck 28 is rotatably connected to the extension plate 26.

[0045] Specifically, when receiving multiple cables 37, the second threaded rod 27 needs to be rotated so that the second threaded rod 27 slides in the transfer plate 25 with the extension plate 26 through the chuck 28, so as to receive cables 37 of different sizes and transfer the cables 37 to the mounting frame.

[0046] like Figures 1 to 8 As shown, multiple transmission components are arranged alternately, a telescopic plate 29 is fixedly connected to one side of the connecting rod 24, a connecting plate 31 is fixedly connected to one side of the telescopic plate 29, the two outermost telescopic plates 29 are fixedly connected to the tilting block 39, and the connecting plate 31 is slidably connected to the transport plate 1.

[0047] Specifically, when the cable 37 is transferred, the alternating arrangement can better transfer the cable 37 and save transfer space, and the transfer component is connected to the transport plate 1 through the telescopic plate 29 and the connecting plate 31, so that the transfer component can better transfer the cable 37.

[0048] Embodiment 2

[0049] like Figures 1 to 8 As shown in Comparative Example 1, another embodiment of the present invention is:

[0050] Two support blocks 33 are fixedly connected to one side of the transport plate 1, a pay-off drum 34 is placed on one side of the two support blocks 33, a cable 37 is wound around the pay-off drum 34, a fifth motor 32 is fixedly connected to one side of the transport plate 1, a second gear 35 is fixedly connected to the output end of the fifth motor 32, a fifth gear 41 is fixedly connected to one side of the pay-off drum 34, and the second gear 35 is meshingly connected to the fifth gear 41.

[0051] Specifically, when releasing the cable 37, the fifth motor 32 can be started to rotate the second gear 35, and the fifth gear 41 can be used to rotate the pay-off reel 34 and gradually release the cable 37 from the pay-off reel 34, and the cable 37 can be laid on the ground in the tunnel. After the laying of the cable 37 is completed, the cable 37 can be lifted and installed. The laying and lifting installation of the cable 37 can be completed by this device, and there is no need to use other cable laying equipment.

[0052] like Figures 1 to 8 As shown, a driving block 2 is fixedly connected to the lower side of the transport plate 1, rotating wheels 3 are arranged on both sides of the driving block 2, a plurality of second cylinders 6 are fixedly connected inside the driving block 2, and transverse wheels 7 are fixedly connected to the output ends of the plurality of second cylinders 6.

[0053] Specifically, when the transport board 1 is moved to lay the cable 37, the driving block 2 drives the rotating wheel 3 to move the transport board 1 and lay the cable 37 with the device. When the tunnel is relatively narrow, the second cylinder 6 can be started to extend the transverse wheel 7, and the transverse wheel 7 can be driven to move the transport board 1 laterally to work close to the cables 37 on both sides.

[0054] Working principle: When laying cables on the side walls of subway tunnels, the cables need to be fixedly installed on the mounting brackets on the side walls of the tunnels. In this embodiment, when laying cables, the connecting frame 12 can be moved by a pushing device such as a cylinder to place multiple cables 37 on the ground into the grooves in the lifting block 15. The second motor 13 in the lifting device is started to rotate the first threaded rod 14, so that the lifting block 15 slides in the connecting frame 12 through the rotation of the first threaded rod 14. The lifting block 15 moves with the multiple cables 37 to lift the multiple cables 37 to the side of the mounting bracket, and places the multiple cables 37 between the two transfer plates 25 on the transfer assembly. At this time, the multiple transfer plates 25 are in a "Y" shape, and the fourth motors 23 are started one by one to transfer the cables 37 on the transfer plates 25 one by one. The cable 37 is passed to the outermost side, and the cable 37 is rotated from the outermost transfer plate 25 to the side of the tilting block 39. The transfer plate 25 is continuously rotated to make the cable 37 slide out of the transfer plate 25 and the transfer assembly along the inclined surface of the tilting block 39, and the cable 37 can be passed to the mounting frame through the transfer plate 25 and the tilting block 39 for subsequent installation and fixation, so that multiple cables 37 can be directly lifted to the installation height through the lifting block 15, and there is no need for workers to lift and place the cables 37 one by one in the mounting frame; this solves the problem that when laying cables, workers need to lift and fix multiple cables one by one on the mounting frame when laying cables on the ground, and multiple cables can be lifted together to the installation height for installation, which reduces the workload of workers in laying cables and greatly improves the efficiency of cable laying;

[0055] When placing the cable 37 on the lifting block 15, the fourth gear 30 is started to rotate the sixth motor 17, and the third threaded rod 38 is rotated to rotate the third threaded rod 38 to move the connecting frame 12 in the transport plate 1. The initial position connecting frame 12 is located close to the sixth motor 17 to facilitate the transport plate 1 to move into the tunnel. When the connecting frame 12 moves from the side close to the sixth motor 17 to the side away from the sixth motor 17, the cable 37 can be shoveled into the lifting block 15; the arc surface 16 can protect the cable 37 when shoveling it into the lifting block 15. 7 will not be hard damaged, so that the cable 37 can be better moved into the lifting block 15. When the transport plate 1 is moved to lay the subsequent cable 37, the cable 37 will slide on the rotating rod 18, protecting the cable 37 from hard damage when the transport plate 1 moves; when the cable 37 is pushed to the mounting frame, the first cylinder 4 is started to move the translation block 10 through the connecting block 5, and the translation block 10 moves the fourth motor 23 through the slider 22 to move the transmission component to the installation height. At this time, the fourth motor 23 can be started to place the cable 37 in the mounting frame at a fixed height;

[0056] When the cables 37 on one side are lifted, the first gear 9 rotates when the first motor 8 is started, and the translation block 10 slides in the connecting block 5 through the row of teeth 11, and the pushing device and the transmission assembly are moved to the other side of the transport plate 1, so that the cables 37 on the other side can be lifted, and the side where the cables 37 have completed the lifting work can be used for staff to walk, move and fix the cables 37; when lifting multiple cables 37, the initial position of the slider 22 is placed on the smooth rod 40, and the bidirectional lead screw 20 is located on both sides of the smooth rod 40 and has two reverse threads. At this time, starting the third motor 19 to rotate the bidirectional lead screw 20 will not move the slider 22, and when the push block 21 is pushed, it can be The slider 22 is meshed and moved with the bidirectional screw rod 20, and the slider 22 moves multiple transmission components to a suitable position to receive the cables 37, so that the multiple cables 37 can be lifted and pushed one by one to the mounting frame; when receiving multiple cables 37, it is necessary to rotate the second threaded rod 27 so that the second threaded rod 27 can slide in the transmission plate 25 with the extension plate 26 through the chuck 28, so that cables 37 of different sizes can be received and the cables 37 can be transferred to the mounting frame; when transferring the cables 37, the alternating arrangement can better transfer the cables 37 and save transfer space, and the transfer component is connected to the transport plate 1 through the telescopic plate 29 and the connecting plate 31, so that the transfer component can better transfer the cables 37;

[0057] When laying the cable 37, the fifth motor 32 can be started to rotate the second gear 35, and the fifth gear 41 can be used to rotate the pay-off reel 34 and gradually pay out the cable 37 from the pay-off reel 34, and lay the cable 37 on the ground in the tunnel. After the laying of the cable 37 is completed, the cable 37 is lifted and installed. The laying and lifting installation of the cable 37 can be completed by the present device, and no other cable laying equipment is needed. When the moving transport plate 1 is used to lay the cable 37, the driving block 2 drives the rotating wheel 3 to move the transport plate 1 and lay the cable 37 with the present device. When the tunnel is relatively narrow, the second cylinder 6 can be started to extend the transverse wheel 7, and the transverse wheel 7 can be driven to move the transport plate 1 laterally to work close to the cables 37 on both sides.
