Technical Field

[0001] This utility model relates to the field of line laying technology, specifically a precision positioning construction device for laying cable television network coverage lines. Background Technology

[0002] Cable television network coverage requires pre-excavation of pits in walls and underground to lay pipes, and then laying cable harnesses in the pipes. Players can be connected indoors to play audio or video on a display screen, thereby connecting to the external network for information exchange. At this time, a positioning installation tool is needed to pull the cable harnesses in the pipes to move them.

[0003] These types of pipes have small diameters and narrow chambers, requiring the use of a positioning installation device to move within the pipe and carry the wiring harness. The GPS positioning system guides the wiring harness to different locations, and then it is connected via a socket for use by playback devices. Traditional positioning installation devices are often designed to fit pipes with a specific inner diameter, leaving gaps during movement. This hinders the stability of the positioning installation device's movement and affects the transportation speed.

[0004] Now, a new type of precision positioning construction device for cable television network coverage line laying is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a precise positioning construction device for laying cable television network coverage lines, so as to solve the problem of limited compatibility specifications mentioned in the background art.

The housing is horizontally arranged inside, and grooves are respectively provided at the front and rear ends of the housing. Push plates are movably connected between the left and right sides of the grooves, and sliders are fixed on both sides of the push plates. Rectangular grooves are respectively provided on the front and rear surfaces of the housing, and a through groove is provided between the rectangular grooves and the grooves. A rod is longitudinally fixed at the center of the rectangular groove. Sleeves are movably connected to the upper and lower sides of the rod. A lever is fixed on the inner side of the sleeve, and a spring is fixed at the center of the lever and the rod. A GPS locator is installed on the left side of the front end of the housing.

[0007] As a further technical solution of this utility model, the sliders are respectively embedded in the two sides of the groove, the springs are wound around the center of the insertion rod surface above and below, and the outer side of the sleeve is fixedly connected to the push plate.

[0008] As a further technical solution of this utility model, arc-shaped grooves are respectively provided on both sides inside the push plate, and rollers are movably connected between the front and rear sides inside the arc-shaped grooves. A worm gear is fixed at the center of the front end of the rollers, and a worm is movably connected between the arc-shaped grooves. A motor is fixed on the right side inside the push plate.

[0009] As a further technical solution of this utility model, the left side of the output end of the motor is fixedly connected to the worm, and the worm is meshed with the worm wheel.

[0010] As a further technical solution of this utility model, slots are respectively provided on both sides of the inside of the housing, and wire harnesses are horizontally inserted and fixed between the slots. Hollow blocks are respectively provided on both sides of the inside of the housing, and a rear support rod is fixed between the rear of the hollow block and the housing. A front support rod is fixed between the front of the hollow block and the housing, and a cylinder is installed inside the front support rod. A clamping pad is fixed behind the output end of the cylinder, and a sponge pad is fixed at the front end inside the hollow block.

[0011] As a further technical solution of this utility model, the clamping pad is located in front of the sponge pad, and the piston rod of the cylinder guides the clamping pad to move back and forth.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the cable TV network coverage line laying precision positioning construction device not only achieves stable machine pushing and synchronous roller rotation, but also prevents the wire harness from loosening;

[0013] (1) The push plates are movably connected between the left and right sides inside the groove. The push blocks are moved along the rectangular grooves at the front and rear, so that the sleeve slides along the surface of the insert rod. The push plates with sliders on both sides are put into the groove. After the housing is inserted into the pipe, the push blocks at the front and rear ends are released, and the spring is allowed to return to its original position. The push plates are pushed out, so that the rollers roll against the inner wall of the pipe. The GPS locator indicates the position of the housing in the pipe and adjusts the contact distance between the housing and the pipe.

[0014] (2) By connecting the rollers between the front and rear of the arc groove, start the motor installed inside the right side of the two sets of push plates, thereby rotating the transverse worm and turning the worm wheel installed at the front end of the roller, forcing each roller to rotate synchronously in the arc groove, so that the housing can move synchronously after the push plate distance is adjusted, and lock the position of the housing through the self-locking structure of the worm and worm wheel to prevent it from sliding on its own.

[0015] (3) Hollow blocks are set on both sides inside the housing. The wire harness is inserted horizontally into the slot of the housing. The clamping pad installed behind the piston rod is pushed by the cylinder and clamped and fixed in front of the sponge pad. This can prevent the wire harness from loosening inside the housing, making it convenient for the housing to carry the wire harness in the pipeline for positioning and installation. After completion, the clamping pad is removed by the cylinder to remove the wire. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4An embodiment of this utility model provides a precise positioning construction device for laying cable television network coverage lines, including a housing 1 and a pipe 12. The housing 1 is arranged horizontally inside, and grooves 9 are respectively provided at the front and rear ends of the housing 1. Push plates 2 are movably connected between the left and right sides of the grooves 9, and sliders 11 are fixed on both sides of the push plates 2. Rectangular grooves 17 are respectively provided on the front and rear surfaces of the housing 1, and a through groove 14 is provided between the rectangular grooves 17 and the grooves 9. A rod 16 is longitudinally fixed at the center of the rectangular grooves 17. A sleeve 10 is movably connected to the upper and lower sides of the outside of the rod 16. A lever 15 is fixed on the inner side of the sleeve 10, and a spring 13 is fixed at the center of the lever 15 and the rod 16. A GPS locator 25 is installed on the left side of the front end of the housing 1.

[0023] The sliders 11 are respectively embedded in the two sides of the groove 9, the springs 13 are wrapped around the top and bottom of the center of the insert rod 16, and the outer side of the sleeve 10 is fixedly connected to the push plate 2.

[0024] Specifically, such as Figure 1 and Figure 2 As shown, by moving the lever 15 along the rectangular groove 17 at the front and rear, the sleeve 10 slides along the surface of the insert rod 16 so that the push plate 2 with sliders 11 on both sides can be put into the groove 9. After inserting the housing 1 into the pipe 12, the levers 15 at both ends are released, allowing the spring 13 to return to its original position, pushing the push plate 2 out, so that the roller 3 rolls against the inner wall of the pipe 12, and the GPS locator 25 indicates the position of the housing 1 in the pipe 12.

[0025] Arc grooves 18 are provided on both sides inside the push plate 2, and rollers 3 are movably connected between the front and rear of the arc grooves 18. A worm gear 4 is fixed at the center of the front end of the rollers 3. A worm 5 is movably connected between the arc grooves 18. A motor 6 is fixed on the right side inside the push plate 2. The left side of the output end of the motor 6 is fixedly connected to the worm 5. The worm 5 is meshed with the worm gear 4.

[0026] Specifically, such as Figure 1 and Figure 3 As shown, the motors 6 installed inside the right side of the two sets of push plates 2 are started, thereby rotating the transverse worm 5 and turning the worm wheel 4 installed at the front end of the roller 3, forcing each roller 3 to rotate synchronously in the arc groove 18, so that after the distance of the push plate 2 is adjusted, the housing 1 can move synchronously, and the position of the housing 1 can be locked by the self-locking structure of the worm 5 and worm wheel 4 to prevent the housing 1 from continuing to move in the pipe 12.

[0027] The inner sides of the housing 1 are provided with slots 8 respectively, and wire harnesses 7 are horizontally inserted and fixed between the slots 8. Hollow blocks 19 are provided on both sides of the inner side of the housing 1. A rear support rod 20 is fixed between the rear of the hollow block 19 and the housing 1. A front support rod 24 is fixed between the front of the hollow block 19 and the housing 1. A cylinder 23 is installed inside the front support rod 24. A clamping pad 22 is fixed behind the output end of the cylinder 23. A sponge pad 21 is fixed at the front end inside the hollow block 19. The clamping pad 22 is located in front of the sponge pad 21. The piston rod of the cylinder 23 guides the clamping pad 22 to move back and forth.

[0028] Specifically, such as Figure 1 and Figure 4 As shown, the wire harness 7 is inserted horizontally into the slot 8 of the housing 1. The clamping pad 22 installed behind the piston rod of the cylinder 23 pushes the wire harness 7 and clamps and fixes it in front of the sponge pad 21. This can prevent the wire harness 7 from becoming loose inside the housing 1, and make it convenient for the housing 1 to carry the wire harness 7 together in the pipe 12 for positioning and installation.

[0029] Working principle: In use, the wire harness 7 is first inserted horizontally into the slot 8 of the housing 1. The cylinder 23 pushes the wire harness 7 with the clamping pad 22 installed behind the piston rod, and clamps and fixes it in front of the sponge pad 21, which can prevent the wire harness 7 from loosening inside the housing 1. Then, the lever 15 is moved along the rectangular groove 17 at the front and rear, so that the sleeve 10 slides along the surface of the insertion rod 16, so that the push plates 2 with sliders 11 on both sides can be put into the groove 9, and the housing 1 can be inserted into the tube. After the push plate 12 is in place, release the levers 15 at both ends and allow the spring 13 to return to its original position. Push the push plate 2 out so that the roller 3 rolls against the inner wall of the pipe 12. Simply start the motors 6 installed inside the right side of the two sets of push plates 2, thereby rotating the transverse worm gear 5 and turning the worm wheel 4 installed at the front end of the roller 3. This forces each roller 3 to rotate synchronously in the arc groove 18 so that after the distance of the push plate 2 is adjusted, the housing 1 can move synchronously. The GPS locator 25 indicates the position of the housing 1 in the pipe 12.
