Description

Technical Field

[0001] This invention relates to the field of optical cable installation and inspection technology, and in particular to an unmanned laying and inspection device for optical cable installation. Background Technology

[0002] Optical fiber cable is a communication cable assembly that uses one or more optical fibers encased in a protective sheath as the transmission medium and can be used individually or in groups. It mainly consists of optical fibers, a plastic protective sheath, and a plastic outer jacket. Optical signals are transmitted through the optical fibers. Currently, optical cables are primarily laid underground in conduits. However, the narrow conduits do not allow for operator access inside, necessitating the use of installation ropes during installation. This not only limits the laying method and distance but also makes subsequent fiber inspection extremely difficult. Summary of the Invention

[0003] The technical problem that this invention aims to solve is that currently, optical cables laid in ducts are mainly operated by installing pull ropes. This operation not only limits the laying method and distance of the optical cables, but also makes subsequent testing of the optical fibers extremely difficult.

[0004] The technical solution adopted by the present invention to solve its technical problem is: an unmanned laying and detection device for optical cable installation, comprising a main body, electrically controlled flip-type support arms movably mounted on both side walls of the main body, lateral support drive wheels movably mounted at the ends of the electrically controlled flip-type support arms, an inverted T-shaped bottom mounting frame mounted at the bottom of the main body, a centrally located bottom support wheel and a side-mounted elastic support wheel movably mounted on the bottom surface of the bottom mounting frame, two symmetrically arranged arc-shaped guide rails fixedly mounted on the side wall of the bottom mounting frame, an electrically controlled rotating frame slidably mounted inside the arc-shaped guide rails, and an electrically controlled detection module fixedly mounted on the inner side of the electrically controlled rotating frame.

[0005] The main body has an internal lifting groove for installing and adjusting the bottom assembly frame.

[0006] The main body has a built-in electric control screw fixedly mounted on its upper surface, and the bottom mounting frame is movably assembled with the main body on the built-in electric control screw through an internal threaded lifting sleeve.

[0007] The bottom assembly frame has lateral compression frames on both sides for mounting side-mounted elastic support wheels.

[0008] The electrically controlled rotating frame includes a rotating adjustment frame that is slidably inserted inside the arc-shaped guide rail, a first adjustment motor and a second adjustment motor fixed on the side wall of the arc-shaped guide rail, and an adjustment gear.

[0009] The rotating adjustment frame has a loading and unloading notch, and the inside of the rotating adjustment frame has a circular mounting and fixing groove for fixing the electronic control detection module.

[0010] The main body has lateral mounting grooves on both sides for assembling the electrically controlled flip-type support arm.

[0011] The electrically controlled flip-type support arm includes a lateral adjustment arm that is movably mounted inside a lateral mounting groove via a connecting shaft, and an upper control support rod for controlling the lateral adjustment arm.

[0012] The main body has end slots at both the front and rear ends, and an electronically controlled adjustment cover for installing an electronic camera is movably fitted inside the end slots.

[0013] LED lamp bodies for lighting are fixedly mounted on the upper and lower ends of the electronically controlled adjustment cover and on both sides of the main body.

[0014] The beneficial effects of this invention are:

[0015] (1) The unmanned laying and testing device for optical cable installation of the present invention can greatly reduce the difficulty of manual operation by using unmanned robots to lay and test optical cables located inside the pipeline.

[0016] (2) By setting up electrically controlled flip-type support arms on both sides, the height of the main body can be adjusted and limited according to the size of the pipe, which can be adapted to pipes of different states and specifications, and has a wider range of applications.

[0017] (3) The entire device uses a height-adjustable inverted T-shaped bottom mounting frame to install and guide the optical cable, and can pull or guide the internal optical fiber, greatly reducing the initial installation and subsequent testing and maintenance.

[0018] (4) The entire device is controlled by an electrically controlled rotating frame and an electrically controlled detection module, which can perform a surround-type electrically controlled detection of the cable, thereby accurately detecting the faults and status of the optical cable during operation, and the detection data is comprehensive and accurate.

[0019] (5) By adopting an electrically controlled rotating frame with notches and an open bottom assembly frame, the installed optical fiber can be installed and removed, making it more convenient to use.

[0020] (6) It adopts a self-propelled structure design, which makes operation more convenient, and the suspended structure design allows for easy internal movement;

[0021] (7) The bottom of the main body is equipped with a height-adjustable inverted T-shaped bottom mounting frame, which can freely adjust the height and mounting method of the optical cable. Attached Figure Description

[0027] 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.

[0028] 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.

[0029] Figure 1 , Figure 2 , Figure 3 and Figure 4 The unmanned laying and detection device for optical cable installation shown includes a main body 1. Electrically controlled flip-type support arms 2 are movably mounted on both side walls of the main body 1. Lateral support drive wheels 3 are movably mounted at the ends of the electrically controlled flip-type support arms 2. A bottom mounting frame 4 with an inverted T-shaped structure is mounted at the bottom of the main body 1. A centrally located bottom support wheel 5 and a side-mounted elastic support wheel 6 are movably mounted on the bottom surface inside the bottom surface of the bottom mounting frame 4. Two symmetrically arranged arc-shaped guide rails 7 are fixedly mounted on the side wall of the bottom mounting frame 4. An electrically controlled rotating frame 8 is slidably mounted inside the arc-shaped guide rails 7. An electrically controlled detection module 9 is fixedly mounted on the inner side of the electrically controlled rotating frame 8.

[0030] Working principle: The main body 1 is flipped downward by the electrically controlled flip-type support arms 2 on both sides, supporting the inner walls of the cable laying duct. Then, the optical cable is lifted and placed on the bottom assembly frame 4, supported by the central bottom support wheel 5 and the side elastic support wheel 6. The lateral support drive wheel 3 provides support and drive, and then drives the main body 1 to move and adjust inside the cable laying duct. During the translation, the electrically controlled rotating frame 8 rotates and adjusts along the periphery of the optical cable. The electrically controlled detection module 9 simultaneously detects the optical cable, and then detects the surface damage, surface temperature and internal humidity of the optical cable in real time.

[0031] To facilitate bottom lifting adjustment, the main body 1 has an internal lifting groove 10 for installing and adjusting the bottom mounting frame 4.

[0032] To facilitate height adjustment, a built-in electric control screw 11 is fixedly mounted on the upper surface of the main body 1, and the bottom mounting frame 4 is movably assembled with the main body 1 by means of an internal threaded lifting cylinder 12 fitted onto the built-in electric control screw 11.

[0033] The built-in electric control screw 11 rotates electrically, and then controls the bottom assembly frame 4 to rise and fall within the internal lifting groove 10. At this time, the height of the optical cable can be adjusted. When the bottom assembly frame 4 descends, the bottom of the optical cable is supported by the central bottom support wheel 5 and the side elastic support wheel 6. When the bottom assembly frame 4 rises, the ground of the main body 1 is pressed and fixed to the upper surface of the optical cable. At this time, the equipment can pull the optical cable to move horizontally inside the cable laying duct.

[0034] To facilitate lateral compression and limiting, the bottom assembly frame 4 has lateral compression frames 13 on both sides for mounting the lateral elastic support wheels 6.

[0035] The optical cable is placed on both sides of the bottom assembly frame 4, and then supported and guided by the central bottom support wheel 5 and the side elastic support wheel 6. The side elastic support wheel 6 can be adapted to optical cables of different diameters and specifications.

[0036] To facilitate angle adjustment, the electrically controlled rotating frame 8 includes a rotating adjustment frame 81 that is slidably inserted inside the arc-shaped guide rail 7, a first adjustment motor 82 and a second adjustment motor 83 fixed on the side wall of the arc-shaped guide rail 7, and an adjustment gear 84.

[0037] The outer arc-shaped surface of the rotating adjustment frame 81 is provided with an arc-shaped tooth groove that meshes with the adjustment gear 84. At this time, the first adjustment motor 82 and the second adjustment motor 83 synchronously rotate the rotating adjustment frame 81, thereby controlling the rotating adjustment frame 81 to rotate along the arc-shaped guide rail 7. In this way, the entire electrically controlled rotating frame 8 can drive the electrically controlled detection module 9 to rotate and detect the optical cable.

[0038] To facilitate installation and adjustment, the rotating adjustment frame 81 has a loading and unloading notch, and the interior of the rotating adjustment frame 81 has a circular mounting and fixing groove for fixing the electrical control detection module 9.

[0039] The electrical control detection module 9 includes an infrared detection module, a humidity detection module, and an ultraviolet detection module. The infrared detection module is used to detect the temperature of the optical cable, while the ultraviolet detection module is used to detect the degree of damage to the surface of the optical cable, and the humidity monitoring module is used to detect the internal humidity.

[0040] To facilitate lateral assembly, side mounting grooves are provided on both sides of the main body 1 for assembling the electrically controlled flip-type support arm 2.

[0041] In order to coordinate with the control of the lateral adjustment arm 21 for angle adjustment, the electrically controlled flip-type support arm 2 includes a lateral adjustment arm 21 that is movably mounted inside the lateral mounting groove via a connecting shaft and an upper control support rod 22 for controlling the lateral adjustment arm 21.

[0042] The lateral adjustment arm 21 is a telescopic structure, including a flip arm with the pivot inside the lateral mounting groove and an embedded telescopic rod fixed inside the flip arm. The extended end of the embedded telescopic rod is equipped with a lateral transmission frame for mounting the lateral support drive wheel 3.

[0043] The upper control strut 22 adjusts the tilt angle of the lateral adjustment arm 21 by telescopic adjustment, thereby adjusting the tilt angle of the lateral adjustment arms 21 on both sides, thus changing the height and position of the main body 1 inside the cable laying duct.

[0044] To facilitate end assembly, end slots are provided at both the front and rear ends of the main body 1, and an electronically controlled adjustment cover 15 for mounting the electronic camera 14 is movably installed inside the end slots.

[0045] The electronically controlled adjustment cover 15 includes a flip cover housing disposed in an end slot and an angle adjustment motor fixed inside the flip cover housing. The angle adjustment motor is rotated to control the angle adjustment of the flip cover housing, thereby adjusting the shooting angle of the electronic camera 14.

[0046] To improve detection accuracy and facilitate observation of the internal condition, LED lamp bodies 16 for illumination are fixedly installed on the upper and lower ends of the electronically controlled adjustment cover 15 and on both sides of the main body 1.

[0047] The interior of the cable duct is illuminated by LED lights 16 in four directions, which can be combined with the detection accuracy of the electronic camera 14 and the electrical control detection module 9.

[0048] 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.
