Description

Technical Field

[0001] This invention relates to the field of optical cable laying and material conveying technology, and in particular to a conveying mechanism for laying underground optical cables in pipelines. Background Technology

[0002] With the rapid development of data driven by the new generation of digital technology revolution, data has become the fifth major factor of production after land, labor, capital, and technology. Optical fiber cable, as a communication cable assembly, is the primary means of data transmission. It mainly consists of one or more optical fibers, which are encased in a protective sheath and covered by an outer PVC tubing. The main function of optical fiber cable is to transmit optical signals through optical fibers, enabling high-speed, high-capacity data transmission.

[0003] Currently, optical cables are mainly laid using underground pipelines. This method greatly limits manual operation, especially for laying cables inside long pipelines. In addition, the existing method can lead to messy cable laying, which greatly increases the difficulty and cost of later maintenance. Summary of the Invention

[0004] The technical problem that this invention aims to solve is that current optical cable laying methods are subject to significant limitations on manual operation, and the existing laying methods also lead to chaotic optical cable laying, greatly increasing the difficulty and cost of later maintenance.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a pipeline buried optical cable laying and conveying mechanism, including an arc-shaped main frame and an adjusting motor installed on the top surface inside the arc-shaped main frame. Arc-shaped adjusting frames are slidably assembled on the front and rear sides of the arc-shaped main frame. Side-mounted guide wheels are movably assembled on both sides of the arc-shaped adjusting frames. Two electric drive wheels are movably installed on the outer arc-shaped surface of the arc-shaped adjusting frames through an electrically controlled telescopic frame. A first arc-shaped electrically controlled extension arm and a second arc-shaped electrically controlled extension arm are movably assembled on both sides of the adjusting motor on the top surface inside the arc-shaped main frame. Replaceable laying rings are axially fixed at the ends of the first arc-shaped electrically controlled extension arm and the second arc-shaped electrically controlled extension arm.

[0006] The outer arc-shaped main frame has symmetrical arc-shaped adjustment grooves on the front and rear ends for installing arc-shaped adjustment frames.

[0007] The outer arc-shaped adjustment frame is provided with an arc-shaped top adjustment tooth groove, and a worm gear assembly for transmission connection between the arc-shaped top adjustment tooth groove and the adjustment motor is installed on the outer arc-shaped adjustment frame.

[0008] The electrically controlled telescopic frame includes a first triangular assembly frame fixed to the front end of the outer arc surface of the arc-shaped adjustment frame, a second triangular assembly frame fixed to the rear end of the outer arc surface of the arc-shaped adjustment frame, an internal electrically controlled adjustment support rod fixed inside the first and second triangular assembly frames, and a telescopic assembly frame slidably assembled to the outer ends of the first and second triangular assembly frames.

[0009] The inner top surface of the arc-shaped main frame is provided with an arc-shaped top-mounted storage groove for installing the first arc-shaped electrically controlled extension arm and the second arc-shaped electrically controlled extension arm.

[0010] Both the first arc-shaped electrically controlled extension arm and the second arc-shaped electrically controlled extension arm include an arc-shaped adjusting arm movably installed on one side inside the arc-shaped top-mounted storage groove, an inner support rod movably installed on the other side inside the arc-shaped top-mounted storage groove, and an electrically controlled extension arm slidably mounted on the arc-shaped adjusting arm.

[0011] The inner arc surface of the arc-shaped adjusting arm is provided with an arc-shaped expansion groove for sliding assembly of the electrically controlled extension arm. The electrically controlled extension arm includes a horizontal drive motor fixed to the inner arc surface of the arc-shaped adjusting arm by a lateral frame, a drive gear axially fixed to the lateral drive shaft of the horizontal drive motor, and an arc-shaped extension arm slidably assembled inside the arc-shaped expansion groove.

[0012] The outer end of the arc-shaped extension arm is provided with an end flip assembly groove for installing a replaceable laying ring.

[0013] The replaceable laying ring includes a flip assembly seat that is movably mounted inside the end flip assembly slot via a shaft, a modular laying ring that is bolted to the outer end of the flip assembly seat, an arc-shaped clamping plate that is movably mounted on the inner arc-shaped surface of the modular laying ring, and an adjusting bolt that is threaded onto the outer arc-shaped surface of the modular laying ring.

[0014] The modular laying ring has an internal guide ball movably mounted on one side of the arc-shaped clamping plate.

[0015] The beneficial effects of this invention are: (1) The present invention provides a pipeline buried optical cable laying and conveying mechanism that adopts a variable structure design, which can slide and adjust according to the free space inside the pipeline, so that the optical cable can be laid by pulling inside the pipeline, without the need for pre-buried wires, which greatly reduces the difficulty of early laying and later maintenance. (2) By adopting a self-propelled structure to adjust and translate along the pipeline, it can move inside pipelines of various lengths, reducing the limitations of manual operation; (3) The first arc-shaped electric control extension arm and the second arc-shaped electric control extension arm are movably assembled on both sides of the adjustment motor on the top surface of the arc-shaped main frame. Replaceable laying rings are axially fixed at the ends of the first arc-shaped electric control extension arm and the second arc-shaped electric control extension arm. The position of the optical cable can be set as needed to improve the stability of the laying and improve the utilization rate of the internal space during the laying. (4) The uniform laying method can avoid the tangling and crossing caused by traditional rope laying, which is convenient for later maintenance; (5) The installation is carried out by hoisting to avoid the top of the cable scraping against the surface of the internal optical cable and to reduce the difficulty of installation; (6) By adopting a modular structural design, adaptability can be improved, enabling it to be compatible with optical cables of different specifications; (7) Two electric drive wheels are installed on the outer arc surface of the arc adjustment frame through the electric control telescopic frame. During the unfolding process, the translational stability of the entire equipment can be guaranteed, and it can also be adapted to pipes with different inner diameters. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0022] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] Figure 1 , Figure 2 , Figure 3 and Figure 4 The illustrated duct-buried optical cable laying and conveying mechanism includes an arc-shaped main frame 1 and an adjusting motor 2 installed on the inner top surface of the arc-shaped main frame 1. Arc-shaped adjusting frames 3 are slidably mounted on the front and rear sides of the arc-shaped main frame 1. Side-mounted guide wheels 4 are movably mounted on both sides of the arc-shaped adjusting frames 3. Two electric drive wheels 6 are movably mounted on the outer arc-shaped surface of the arc-shaped adjusting frames 3 through an electrically controlled telescopic frame 5. A first arc-shaped electrically controlled extension arm 7 and a second arc-shaped electrically controlled extension arm 8 are movably mounted on the inner top surface of the arc-shaped main frame 1 on both sides of the adjusting motor 2. Replaceable laying rings 9 are axially fixed at the ends of the first arc-shaped electrically controlled extension arm 7 and the second arc-shaped electrically controlled extension arm 8.

[0024] Working principle: The arc-shaped main frame 1 is inserted into the opening of the laying pipe. Then, the control switch on the outside of the arc-shaped main frame 1 is used to start the adjustment motor 2. The adjustment motor controls the arc-shaped adjustment frames 3 on both sides to slide downward. Then, the side guide wheels 4 on the outside of the motor squeeze to both sides of the bottom optical cable to form a limit. Then, the four outward-extending electric drive wheels 6 form a drive mechanism on both sides to drive the entire mechanism to move horizontally along the laying pipe. While moving horizontally, the optical cable is laid flat. Then, the optical cable is separated from the opening end and then pulled and laid flat repeatedly. Alternatively, it can be pulled to one end, separated and reset, and then pulled and laid repeatedly. The function of the first arc-shaped electric control extension arm 7 and the second arc-shaped electric control extension arm 8 is to flip downward and then move horizontally layer by layer from the bottom to the sides, and finally complete the uniform laying.

[0025] To facilitate sliding assembly and adjustment, the outer arc-shaped main frame 1 has symmetrical arc-shaped adjustment grooves 10 for mounting the arc-shaped adjustment frame 3 on its front and rear sides.

[0026] In order to facilitate the sliding adjustment of the arc-shaped adjustment frame 3, an arc-shaped top adjustment groove 11 is provided on the outer arc surface of the arc-shaped adjustment frame 3. A worm gear assembly 12 for transmission connection between the arc-shaped top adjustment groove 11 and the adjustment motor 2 is installed on the outer arc surface of the arc-shaped adjustment frame 3.

[0027] The worm gear assembly 12 includes a worm fixed axially to the adjusting motor 2, a worm wheel with a horizontal synchronous shaft fixed inside, and extension gears fixed axially at both ends of the horizontal synchronous shaft. The extension gears mesh with the arc-shaped top adjusting tooth groove 11 for transmission, and the worm and worm wheel mesh for transmission.

[0028] To accommodate expansion and contraction adjustments and thus adapt to pipelines of different diameters, the electrically controlled expansion frame 5 includes a first triangular assembly frame 51 fixed to the front end of the outer arc surface of the arc-shaped adjustment frame 3, a second triangular assembly frame 52 fixed to the rear end of the outer arc surface of the arc-shaped adjustment frame 3, an internal electrically controlled adjustment support rod 53 fixed inside the first triangular assembly frame 51 and the second triangular assembly frame 52, and an expansion assembly frame 54 slidably assembled to the outer ends of the first triangular assembly frame 51 and the second triangular assembly frame 52.

[0029] The built-in electrically controlled adjusting support rod 53 controls the telescopic assembly frame 54 to slide and adjust along the first triangular assembly frame 51 or the second triangular assembly frame 52 by telescopic extension, so that the electric drive wheel 6 is pressed into contact with the inner wall of the pipe. The rotation of the electric drive wheel 6 controls the entire conveying mechanism to move along the inner wall of the pipe, and the laying or inspection is completed during the movement.

[0030] To accommodate the top storage, an arc-shaped top storage groove is provided on the inner top surface of the arc-shaped main frame 1 for installing the first arc-shaped electrically controlled extension arm 7 and the second arc-shaped electrically controlled extension arm 8.

[0031] To facilitate the flipping adjustment, both the first arc-shaped electrically controlled extension arm 7 and the second arc-shaped electrically controlled extension arm 8 include an arc-shaped adjusting arm 781 movably installed on one side inside the arc-shaped top-mounted storage groove, an inner support rod 782 movably installed on the other side inside the arc-shaped top-mounted storage groove, and an electrically controlled extension arm 783 slidably mounted on the arc-shaped adjusting arm 781.

[0032] The inner support rod 782 controls the rotation of the arc-shaped adjusting arm 781 by telescoping, thereby changing the angle between the arc-shaped adjusting arm 781 and the electrically controlled extension arm 783.

[0033] To facilitate sliding extension adjustment, an arc-shaped extension groove 13 is provided on the inner arc surface of the arc-shaped adjustment arm 781 for sliding assembly of the electrically controlled extension arm 783. The electrically controlled extension arm 783 includes a transverse drive motor 7831 fixed to the inner arc surface of the arc-shaped adjustment arm 781 by a lateral frame, a drive gear 7832 axially fixed to the lateral drive shaft of the transverse drive motor 7831, and an arc-shaped extension arm 7833 slidably assembled inside the arc-shaped extension groove 13.

[0034] The transverse drive motor 7831 controls the drive gear 7832 to rotate, thereby driving the arc-shaped extension arm 7833 to slide outward, thus adjusting the total length of the entire electrically controlled extension arm 783 and the arc-shaped adjustment arm 781. This allows for layer-by-layer laying at different lateral positions and heights, ensuring uniform laying and guaranteeing the stability of the conveying mechanism during internal transport.

[0035] To facilitate end assembly, the outer end of the arc-shaped extension arm 7833 is provided with an end flip assembly groove for installing the replaceable laying ring 9.

[0036] To facilitate clamping and securing the optical cable, the replaceable laying ring 9 includes a flip assembly seat 91 that is movably mounted inside the end flip assembly slot via a shaft, a modular laying ring 92 that is bolted to the outer end of the flip assembly seat 91, an arc-shaped clamping plate 93 that is movably mounted on the inner arc-shaped surface of the modular laying ring 92, and an adjusting bolt 94 that is threaded onto the outer arc-shaped surface of the modular laying ring 92.

[0037] The adjusting bolt 94 controls the arc-shaped clamping plate 93 to bend inward by rotating, thereby clamping and fixing the surface of the optical cable inside, which can drive the optical cable to move horizontally inside the pipe.

[0038] Alternatively, the adjusting bolt 94 can be replaced with an electromagnet control, which allows for remote control of the separation of the arc-shaped clamping plate 93 from the surface of the optical cable.

[0039] To reduce lateral friction during the storage transition test, an internal guide ball 95 is movably mounted inside the modular laying ring 92 on one side of the arc-shaped clamping plate 93.

[0040] When it is necessary to perform a sliding test on the optical cable, the arc-shaped clamping plate 93 is elastically reset and adhered to the outside by rotating the adjusting bolt 94 in the opposite direction, losing contact with the surface of the optical cable. At this time, the internal guide ball 95 can roll on the surface of the optical cable to reduce friction and avoid scratching the outer wall of the optical cable.

[0041] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
