Technical Field

[0001] The invention relates to the technical field of cable maintenance equipment adjustment, in particular to an adjustment and conveying device applied to pipeline buried cable maintenance and detection equipment. Background Art

[0002] Cable is a device for transmitting electric energy or signals, usually composed of several or several groups of wires. Its main function is to transmit electric energy and signals. The traditional cable laying method mainly adopts overhead laying. Although this laying method is simple and efficient, it will greatly affect the layout and beauty of the city, and it will also restrict the development of the city, and it is not very safe. Therefore, more and more cities adopt the underground layout method. However, due to the limited internal space of the underground pipeline layout, in order to ensure the stability of the cable operation after laying, the cable needs to be maintained and inspected regularly. However, the current pipeline cannot provide enough operating space for maintenance personnel, resulting in the inability of detection equipment to detect and maintain the cables in the underground pipeline one by one, because a large number of cables are stacked in the same pipeline, which further increases the difficulty of detection and maintenance. In addition, people enter the narrow pipeline, which greatly increases the maintenance and detection costs and greatly reduces safety. Summary of the invention

[0003] The technical problem to be solved by the present invention is that the current detection method cannot detect and maintain the cables in the buried pipeline one by one, because a large number of cables are stacked inside the same pipeline, which further increases the difficulty of detection and maintenance, greatly increases the maintenance and detection costs and greatly reduces safety.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] Figure 1 , Figure 2 , Figure 3 and Figure 4 The shown adjustable conveying equipment is applied to pipeline buried cable maintenance and detection equipment, including a first conveying frame 1, a second conveying frame 2 and an optical detection device 3. A lateral fixed bracket 4 is fixedly installed between the first conveying frame 1 and the second conveying frame 2, and an electric-controlled winch 5 is fixedly installed on the inner top surface of the first conveying frame 1 and the second conveying frame 2. An arc-shaped adjustment groove 6 is opened on the inner arc surface of the first conveying frame 1 and the second conveying frame 2. An internal guide locking block 7 that cooperates with the pull ropes on both sides of the electric-controlled winch 5 is slidably installed inside the arc-shaped adjustment groove 6. An electric-controlled flip-type extension arm 8 is movably installed on the inner side surface of the lateral fixed bracket 4, and an electric-controlled surround adjustment mechanism 9 for installing the optical detection device 3 is provided at the end of the electric-controlled flip-type extension arm 8.

[0032] Working principle: the first conveying frame 1 and the second conveying frame 2 are put on the periphery of the cable to be inspected, and then the pull rope is released by the electric winch 5, and then the internal guide locking block 7 is fixed to the upper side of the set arc-shaped adjustment groove 6, and then the pull rope is put on the bottom of the upper layer of the cable that does not need to be inspected, and then the electric winch 5 begins to retract the pull rope, and the upper layer of the cable that does not need to be inspected is lifted above the first conveying frame 1 and the second conveying frame 2, and then the electric-controlled flip-type extension arm 8 is flipped inward, and the cable to be inspected is set on the periphery of the electric-controlled surround adjustment mechanism 9, and the optical inspection device 3 is driven by the electric-controlled surround adjustment mechanism 9 to rotate the cable in a circle, and then when the first conveying frame 1 and the second conveying frame 2 are translated, the optical inspection device 3 can perform a comprehensive optical inspection on the cable. The optical inspection method is to measure the gap between the optical inspection device 3 and the cable through optical inspection, and judge the damage and cracks on the cable surface by the change in the gap.

[0033] In order to cooperate with the bottom adjustment, the outer arc surfaces of the first conveying frame 1 and the second conveying frame 2 are provided with arc-shaped external telescopic grooves 10 with lower ends opened, and the arc-shaped external telescopic grooves 10 are slidably equipped with an adaptive electric-controlled arc-shaped telescopic frame 12 with guide wheels 11 at the bottom.

[0034] In order to facilitate the adaptive adjustment of the bottom and improve the stability of the equipment inside the pipeline, the adaptive electrically controlled arc-shaped telescopic frame 12 includes an arc-shaped telescopic frame 121 slidably inserted into the arc-shaped external telescopic groove 10, an arc-shaped rack 122 fixed on the inner arc surface of the arc-shaped telescopic frame 121, and an adjustment motor 123 fixed at the opening position of the arc-shaped external telescopic groove 10.

[0035] A guide wheel 11 is set at the bottom of the arc-shaped telescopic frame 121 to support and limit both sides of the bottom cable. Then the adjusting motor 123 is engaged with the arc-shaped rack 122 through the gear. The arc-shaped rack 122 is driven and adjusted by the adjusting motor 123. Then the arc-shaped telescopic frame 121 is slidably adjusted along the inside of the arc-shaped external telescopic groove 10. An electronic level controller for controlling the adjusting motor 123 is fixed on the top surface of the first conveying frame 1 and the second conveying frame 2. Then, the stability of the first conveying frame 1 and the second conveying frame 2 is ensured by telescoping the arc-shaped telescopic frame 121.

[0036] In order to cooperate with the guiding and limiting, the internal guiding locking block 7 includes an arc-shaped adjusting slider 71 slidably assembled in the arc-shaped adjusting groove 6 and locking bolts 72 threadedly assembled on both sides of the arc-shaped adjusting slider 71 .

[0037] In order to cooperate with the lateral limiting, the outer sides of the first conveying frame 1 and the second conveying frame 2 are provided with limiting through holes 13 which are connected with the inside of the arc-shaped adjusting groove 6 .

[0038] The locking bolt 72 penetrates the limiting through hole 13 to be threadably assembled and fixed with the outer side of the arc-shaped adjusting slider 71 , thereby limiting the position of the arc-shaped adjusting slider 71 .

[0039] In order to cooperate with the flip adjustment, the electrically controlled flip extension arm 8 includes a flip adjustment arm 81 movably mounted on the inner side of the lateral fixed bracket 4, a side adjustment support rod 82 for controlling the flip adjustment arm 81, a telescopic adjustment screw rod 83 installed inside the flip adjustment arm 81, an external extension arm 84 axially fixed at the protruding end of the telescopic adjustment screw rod 83, and an arc guide rail 85 fixed on the outside of the external extension arm 84.

[0040] The side adjustment support rod 82 controls the flipping of the flip adjustment arm 81 by telescoping, and then adjusts the relative position between the external extension arm 84 and the flip adjustment arm 81 by telescoping the adjustment screw rod 83, thereby adjusting the position of the arc guide rails 85 on both sides inside the pipeline, so as to adapt to detection cables in different positions.

[0041] A guide spring is also provided on the side wall of the arc-shaped guide rail 85, so that the cable to be detected can always be located between the upper arc-shaped guide rail and the lower arc-shaped guide rail.

[0042] In order to cooperate with the sliding adjustment, the electrically controlled surround adjustment mechanism 9 includes an adjustment slider 91 slidably assembled inside the arc guide rail 85 , a control motor 92 fixed inside the adjustment slider 91 , and a lateral drive wheel 93 driven by the control motor 92 .

[0043] Lateral drive wheels 93 synchronously controlled by a control motor 92 are installed on both sides of the adjustment slider 91. The control motor 92 synchronously drives the lateral drive wheels 93 through the synchronous pulleys on the rotating shafts on both sides, and then controls the adjustment slider 91 to move inside the arc guide rail 85 through the lateral drive wheels 93. By sliding and switching inside adjacent arc guide rails 85, a surround optical detection is performed along the cable, so that a longitudinal surround detection can be performed while translating, thereby completing a surround optical detection of the required detection cable.

[0044] In order to cooperate with the external flipping adjustment limit, the outer sides of the first conveying frame 1 and the second conveying frame 2 are movably equipped with an external arc adjustment frame 14, an external guide wheel 15 connected to the end of the external arc adjustment frame 14 and an external control support rod 16 for controlling the external arc adjustment frame 14.

[0045] The external arc-shaped adjustment frame 14 is controlled to flip and adjust by controlling the extension and contraction of the external control support rod 16, thereby controlling the external guide wheel 15 to flip outward to fit the inner wall of the pipeline, so as to adapt to pipelines of different diameters.

[0046] In order to facilitate flipping adjustment, an arc-shaped flipping opening is opened inside the arc-shaped telescopic frame 121, and an arc-shaped extension arm 17, an external driving wheel 18 movably installed at the end of the arc-shaped extension arm 17 and an internal flipping support rod 19 for controlling the arc-shaped extension arm 17 are movably installed inside the arc-shaped flipping opening.

[0047] The arc-shaped extension arm 17 is controlled to flip outward through the built-in flip support rod 19, so that the external drive wheel 18 is in contact with the inner wall of the pipeline, and then the entire device is controlled to be translated and transported inside the pipeline by rotating the external drive wheel 18.

[0048] In order to match the internal wire, an internal guide channel 20 is opened inside the arc-shaped adjustment slider 71, and an internal guide wheel 21 is movably installed inside the internal guide channel 20.

[0049] The pull ropes on both sides of the electric winch 5 are introduced into the internal guide channel 20 inside the arc-shaped adjustment slider 71 along the arc-shaped adjustment groove 6, and then led out from the opening on the bottom side of the internal guide channel 20 through the internal guide wheel 21, and then connected to each other using the connecting rings at the protruding ends. In this way, a bottom-supported towing rope can be formed under the upper cable that does not need to be detected, and then the pull ropes are tightened from both sides through the operation of the electric winch 5 to lift the upper cable that does not need to be detected to the position set by the arc-shaped adjustment slider 71.

[0050] The internal guide wheel 21 is used to squeeze and reduce the resistance of the pull rope sliding inside the internal guide channel 20 .

[0051] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
