Description

Technical Field

[0001] The present invention relates to the technical field of communication optical cable laying, and in particular to a 5G communication optical cable laying device for construction. Background Art

[0002] Communication optical cable is a cable that uses optical fiber as the transmission medium. It can transmit data, voice, video and other information at extremely high speeds and large capacities. When using communication optical cables, specific devices are required to lay out the communication optical cables. The communication optical cable laying device can ensure the correct deployment of the optical cables, support the safety of the optical fiber cables, reduce potential damage to the optical cables themselves, and improve construction efficiency.

[0003] The existing 5G communication optical cable laying device used in construction moves the frame of the laying device to a suitable laying position, so that the frame is directly above the pre-opened groove on the ground, and then the cable drum with the 5G communication optical cable is installed on the frame, and the 5G communication optical cable on the cable drum is fixed by control and then the frame is driven to move, so that the frame drives the cable drum above it to move, and the optical cable is unfolded during the movement of the cable drum to be laid in the pre-opened groove on the ground, thereby realizing the laying of the 5G communication optical cable. However, in actual use, since the laying vehicle and the cable drum have a large combined weight when moving with the cable drum, it is difficult to control the speed of the laying vehicle, and it may be difficult to lay the cable drum at a stable and uniform speed when laying the optical cable, which may cause displacement at the end of the optical cable during laying, and even cause the optical cable to be damaged due to excessive stretching due to tension when being laid, affecting the subsequent use of the optical cable and causing certain troubles for the laying construction of the 5G communication optical cable. Summary of the invention

[0006] As a further improvement of the present invention, a linkage disk 1 is fixedly provided at one end of the front pin shaft away from the vertical center of the frame, a linkage rod is rotatably provided at one side of the linkage disk 1 away from the vertical center of the frame, a linkage shaft is rotatably provided inside the driving seat, the linkage shafts are respectively fixed to adjacent rotating shafts through couplings, a linkage disk 2 is fixedly provided at one end of the front linkage shaft away from the vertical center of the frame, and the bottom end of the linkage rod is rotatably connected to the adjacent linkage disk 2; a servo motor is provided inside the driving seat on the right side, a bevel gear 2 is provided on the upper end of the output shaft of the servo motor, and a bevel gear 1 is fixedly sleeved on the outer arc surface of the linkage shaft on the right side, and the bevel gear 1 is respectively meshed and connected with the adjacent bevel gear 2.

[0007] As a further improvement of the present invention, a worm is rotatably arranged inside the drive box on the left side, a worm wheel is fixedly sleeved on the left end of the upper rotating shaft, the worm wheels are respectively meshed and connected with adjacent worms, and a dual-axis motor is arranged between the two drive boxes on the left side, and the output shafts of the dual-axis motor are respectively fixed to adjacent worms through couplings.

[0008] As a further improvement of the present invention, a hydraulic telescopic rod 1 is arranged on the front side of the upper surface of the frame, and a bulldozer plate is arranged at the telescopic end of the hydraulic telescopic rod 1; a hydraulic telescopic rod 2 is arranged on the rear side of the upper surface of the frame, and a limited wheel is arranged at the telescopic end of the hydraulic telescopic rod 2; and symmetrically distributed hydraulic control boxes are arranged on the upper surface of the frame, and the hydraulic control boxes are respectively connected to the adjacent hydraulic telescopic rods 1.

[0009] As a further improvement of the present invention, a drive control box is arranged on the upper surface of the frame, and the servo motor, the dual-axis motor and the hydraulic control box are all point-connected to the drive control box.

[0010] In summary, compared with the prior art, the present application has at least one of the following beneficial technical effects:

[0011] Firstly, the drive control box regulates the operation of the dual-axis motor so that the output shafts of the dual-axis motors respectively drive the worm gears connected thereto to rotate. Since a parallelogram structure can be formed between the rotating shaft, the rotating rod and the driving seat, the rotating rods on the left and right sides are driven to rotate synchronously towards each other, driving the U-shaped wheel on the front side and the moving wheel on the rear side to move towards each other and contact and clamp the hanging optical cable.

[0012] Secondly, during the movement of the frame, the drive control box drives the servo motor connected to it to run synchronously, so that the rotating shafts on both sides rotate synchronously towards each other, thereby driving the U-shaped wheel 1 on the front side and the moving wheel on the rear side to rotate synchronously towards each other while clamping the optical cable, which can stably drive the optical cable to be released.

[0013] Thirdly, since the rotating shaft on the upper side is coaxial with the pin shaft, during the rotation of the linkage shaft, the linkage shaft drives the U-shaped wheel 2 on the front side to rotate through the cooperation of the linkage disk 2, the linkage rod and the linkage disk 1. Since the U-shaped wheel 2 is in contact with the optical cable drum, the U-shaped wheel 2 on the front side drives the optical cable drum to rotate during the rotation process, so that the optical cable drum itself rotates to assist in laying out the cable.

[0014] Fourthly, by making the U-shaped wheel 2 rotate synchronously with the rotation of the U-shaped wheel 1, the cable drum is driven to rotate synchronously with the rotation of the U-shaped wheel 1, which can effectively avoid the pulling of the communication optical cable by the release of the cable due to the opposite rotation of the U-shaped wheel 1 and the moving wheel. When laying G communication optical cables, the optical cable can be driven to lay the communication optical cable in the pre-opened groove stably and smoothly according to the walking speed of the laying frame.

[0015] Fifthly, when the horn is passed through, the optical cable unwound on the cable drum can naturally enter the interior of the guide tube, and then be paid out vertically downward through the guide tube, so that the optical cable unwound on the cable drum can be smoothly transformed into a vertical downward direction through the cooperation of the horn and the guide tube, which can effectively assist the normal payment of the cable.

[0027] like Figure 2 , 6 As shown, a hydraulic telescopic rod 1 401 is provided on the front side of the upper surface of the frame 101, and a bulldozer plate 402 is provided at the telescopic end of the hydraulic telescopic rod 1 401; a hydraulic telescopic rod 2 403 is provided on the rear side of the upper surface of the frame 101, and a limit wheel 404 is provided at the telescopic end of the hydraulic telescopic rod 2 403; and symmetrically distributed hydraulic control boxes 405 are provided on the upper surface of the frame 101, and the hydraulic control boxes 405 are respectively connected to adjacent hydraulic telescopic rods 1 401.

[0028] like Figure 1 As shown, a drive control box 501 is disposed on the upper surface of the vehicle frame 101 , and the servo motor 218 , the dual-axis motor 303 and the hydraulic control box 405 are all connected to the drive control box 501 .

[0029] When in use, the optical cable drum 203 with the communication optical cable rolled up is installed between the rotating shaft seats 202, so that the U-shaped wheel 213 on the rotating seat 212 is in contact with the optical cable drum 203, so that the optical cable on the optical cable drum 203 hangs down, and then the driving control box 501 regulates the operation of the dual-axis motor 303, so that the output shafts of the dual-axis motor 303 respectively drive the worm 302 connected thereto to rotate, so that the worm 302 drives the rotating shaft 205 where the worm gear 301 is located to rotate through the meshing relationship between the worm 302 and the worm gear 301. Since the rotating shaft 205, the rotating rod 206 and the driving seat 210 can form a parallelogram structure, the rotating rods 206 on the left and right sides are driven to rotate synchronously, and the U-shaped wheel 1 208 on the front side and the moving wheel 209 on the rear side are driven to move towards each other and contact and clamp the hanging optical cable;

[0030] The driving control box 501 controls the hydraulic control box 405 on the front side and the hydraulic control box 405 on the rear side to operate respectively, so that the hydraulic telescopic rod 401 on the front side drives the bulldozer 402 downward to contact the bottom of the pre-dug trench, and the hydraulic telescopic rod 401 on the rear side drives the limiting wheel 404 downward to contact and limit the optical cable line that has been laid at the bottom of the trench, so that the soil at the bottom of the trench can be leveled by the bulldozer 402 during the movement of the vehicle frame 101, and the limiting wheel 404 contacts and limits the laid optical cable line downward to move it during the movement of the vehicle frame 101;

[0031] The external driving vehicle is connected to the connecting seat 107 through a hook, and the movement of the external driving vehicle causes the running wheels 104 at both ends of the outer arc surface of the wheel rod 103 to rotate, thereby driving the frame 101 to move, and the protective frame 105 and the protective frame 2 106 on the frame 101 can effectively prevent equipment damage caused by scratches during the travel process;
