Description

Technical Field

[0001] The invention relates to the technical field of cable detection, in particular to a railway signal cable detection device. Background Art

[0002] Railway signal cables are the medium for signal transmission. Signal cables include plastic sheathed (PTY03, PTY23), composite sheathed (PTYA23, PTYA22), and aluminum sheathed (PTYL23, PTYL22) signal cables according to the sheath type. Railway signal cables are mostly wound on reels for loading before installation and laying. The reels are used to fix and protect the cables. However, the reels may cause the cables to become messy due to improper transportation during transportation, which results in the need to rewind the cables at the construction site and test the cables to ensure that they can be used normally. Generally, the cables are thicker overall, with thicker inner and outer protective sheaths and internal The wiring harness is not easy to be damaged, but the protective layer of the cable is easily damaged due to scratches and other problems, which affects the service life of the cable and needs to be inspected. However, the wound cable on the reel is generally long, which makes inspection inconvenient. In addition, the reel is usually moved by hoisting. The reel with scattered cables has a changed center of gravity, which makes it inconvenient to hoist it, making it inconvenient to move the reel to a suitable position and use the winding device to rotate and release the cable. Moreover, when the cables on the reel are released, due to their scatteredness, some of the cables to be released may be clamped and squeezed by nearby cables, and the cables need to be pulled out manually.

The cable drum loaded with cables can be naturally stuck between the two supporting mechanisms due to its own weight, and then manually adjust the position of the empty cable drum so that its edge contacts the edge of the cable drum loaded with cables, and then start the pulling mechanism to make the two cable drums rotate synchronously, so that the empty cable drum can pull out and reel the cable on the cable drum loaded with cables, and use the pulling mechanism to detect the outer layer of the pulled out cable, and then the pulled out cable can be limited by the guiding mechanism and wound onto the empty cable drum in sequence, so that it is convenient for users to rewind the cable and detect the damage of the cable surface.

[0020] 2. Push the wire reels loaded with scattered cables and the empty wire reels onto the rollers on the two supporting mechanisms by pushing them on the ground, and then start the four hydraulic cylinders to drive the adjacent sliding rods to move, so that the sliding rods drive the adjacent supporting rods to lift the adjacent rotating arms, so that the rotating arms on the two supporting mechanisms are rotated to incline, so that the wire reels loaded with cables are naturally stuck between the two rotating arms on the same U-shaped plate due to their own weight, and then manually adjust the lighter empty wire reels to make the edges of the two wire reels collide, and then manually adjust the positions of the two moving frames, and start the two hydraulic cylinders to drive the two arc frames to press down, so that the resistance wheel conflicts with the edge of the wire reels loaded with cables and clamps the wire reels, and start the drive motor to drive the adjacent wire reels to rotate through the resistance wheel, so that the wire reels loaded with cables drive the conflicting empty wire reels to rotate synchronously;

[0021] 3. After the cable end on the reel loaded with scattered cables passes through the cylinder, positioning ring, moving ring, circular hole, rubber tube and sleeve ring in sequence, it is fixed on the empty reel, and then the two reels are rotated to make one reel release the cable and the other reel reel up the cable.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-Figure 7 In an embodiment of the present invention, a railway signal cable detection device includes:

[0033] Two U-shaped plates 100, two supporting mechanisms 200 for supporting the cable drum, a pulling mechanism 300 for pulling the cable on the cable drum, and a guiding mechanism 400 for redirecting the cable winding, the two U-shaped plates 100 are arranged parallel to each other, the two supporting mechanisms 200 are fixedly connected to the two U-shaped plates 100, respectively, the supporting mechanism 200 includes two guide rails 210, and the adjacent ends of the two guide rails 210 are respectively fixedly connected to the opposite sides of the adjacent U-shaped plates 100, and the two guide rails 210 are each provided with a rotating arm 220, and the two rotating arms 220 are connected to the two U-shaped plates 100. The two ends are rotatably connected between the two opposite inner walls of the adjacent U-shaped plates 100, the two guide rails 210 are slidably clamped with sliding rods 230, and the two sliding rods 230 are rotatably connected at one end away from each other with support rods 231, one end of the two support rods 231 is rotatably connected to the other end of the two rotating arms 220, and a plurality of rollers 221 are rotatably connected between the two rotating arms 220 that are respectively located on the two supporting mechanisms 200 and are parallel. The pulling mechanism 300 is located above the two U-shaped plates 100, and the guiding mechanism 400 is located on one side of the pulling mechanism 300.

[0034] Specifically, in the initial state, two U-shaped plates 100 stand on the ground, so that the four rotating arms 220 are respectively attached to the four guide rails 210, so that the four rotating arms 220 are parallel to the ground, so that the user can move the cable reels loaded with scattered cables and the empty cable reels to the rollers 221 on the two support mechanisms 200. The cable reels can be directly pushed to roll onto the rollers 221 on the two support mechanisms 200, and then the sliding bars 230 on the four guide rails 210 can be slid to make the cable reels roll onto the rollers 221 on the two support mechanisms 200. The slide bar 230 pulls the adjacent support bar 231 to rotate and lift up the four rotating arms 220, so that the four rotating arms 220 rotate to an inclined state, so that the rollers 221 on the four rotating arms 220 lift up the two wire drums, and the wire drum loaded with cables can be automatically stuck between the rotating arms 220 on the opposite sides of any U-shaped plate 100 due to its own weight, and the edge of the vacant wire drum naturally contacts the edge of the wire drum loaded with cables due to its own weight, and then the edge of the wire drum loaded with cables is rotated to make its edge rub the edge of the vacant wire drum , the cable drum loaded with cables can drive the empty cable drum to rotate, so that the cables on the cable drum loaded with cables can be rewound onto the empty cable drum through the pulling mechanism 300 and the guiding mechanism 400, and the cables can be detected during the winding process, so that it is convenient for users to rewind and detect the cables. When the cable drum is transported to the roller 221, the cable drum can be directly pushed onto the roller 221. The cable drum can be naturally stuck between two adjacent rollers 221 due to the large diameter disks at both ends of the cable drum, which is convenient for users to move the cable drum. The edges of the empty cable drum and the loaded cable drum can be attached with a rubber layer to increase the friction between the cable drums, so that when the edges of the two cable drums contact each other, the rotation of any cable drum can drive the adjacent cable drum to rotate synchronously. Since there is no cable loaded on the empty cable drum, the user can directly adjust the position of the cable drum manually or with tools to make its edge contact with the cable drum loaded with cables. The roller 221 can rotate to facilitate the rotation of the cable drum loaded with cables and the empty cable drum thereon.

The user can start the linear motor 1 to make the L-shaped frame 350 close to the cable part that is passing through the positioning ring 353, and release the cable by rotating the cable drum loaded with cables. The empty cable reels the cable to pull the scattered cables on the cable drum, which is convenient for the scattered cables to be pulled. The cable can be pulled out from the cable reel loaded with the cable, and in the process of pulling out the cable, the electric push rod 320 can be started, and the movable ring 352 can be used to pull the cable part wound on the cable reel, so that the cable part that is about to pass through the positioning ring 353 can be pulled out from the inside of the scattered cable, so that the cable can be wound onto the empty cable reel after passing through the positioning ring 353. The user can install a camera module on the movable ring 352, and move the movable ring 352 back and forth, so that the camera module can shoot the surface condition of the cable, and cooperate with the machine vision technology to detect the damage of the cable surface.

[0042] In specific implementation, the cable is passed through the interior of the cylinder 372, the interior of the positioning ring 353, the interior of the moving ring 352 and the circular hole in sequence and then fixed to an empty wire drum. The two-way push rod 341 is a two-way oil cylinder with two movable ends moving in opposite directions, and when one movable end of the two-way oil cylinder moves, it will drive the other movable end of itself to move in the same direction. By starting the two-way push rod 341, the moving ring 352 can be driven to reciprocate in the slide groove through the pull rope 354, and while the moving ring 352 reciprocates, the cylinder 372 can be driven to reciprocate in the adjacent rail 360 through the guide rope 371. The rail 360 is divided into a straight portion and an arc portion, so that when the cylinder 372 reciprocates along the rail 360, the cylinder 372 can reciprocate to squeeze the cable squeezed against the cable passing through the cylinder 372 through the reciprocating movement, so that the cable can be pulled out from the wire drum loaded with the cable in sequence.

[0043] like Figure 3-Figure 4 As shown, in the present embodiment, two movable frames 380 are slidably sleeved on the outer side wall of the driving box 310, and cutting grooves are provided on both sides of the top and bottom of the movable frames 380, and a plurality of movable wheels 381 are rotatably connected between the two opposite inner side walls of any cutting groove, a hydraulic cylinder 2 390 is fixedly connected to the center of the bottom surface of the two movable frames 380, and the movable ends of the two hydraulic cylinders 2 390 are fixedly connected to an arc frame 391, a plurality of resistance wheels 392 are rotatably connected between the two opposite inner side walls of any arc frame 391, a motor box 393 is fixedly connected to one side of any arc frame 391, a driving motor is arranged inside any motor box 393, and the motor shaft of any driving motor is fixedly connected to the wheel axle of the adjacent resistance wheel 392.

[0044] In specific implementation, when the cable drum loaded with cables is located between the two rotating arms 220 on any supporting mechanism 200, the two movable frames 380 can be manually pulled to slide to the appropriate position, and then the two hydraulic cylinders 390 are started to drive the abutting wheels 392 on the two arc frames 391 to abut the edge of the cable drum, and the cable drum loaded with cables is clamped to be positioned, and then the adjacent abutting wheels 392 are driven to rotate by starting the driving motor, and the abutting wheels 392 can drive the cable drum loaded with cables to rotate.

[0048] Embodiment 2

[0049] On the basis of the first embodiment, the rubber tube 441 is provided to facilitate the detection of the surface of the cable in a bent state.

[0050] like Figure 6-7 As shown, in this embodiment, a rubber tube 441 is fixedly connected between one side of the collar 440 and one side of the short arm of the L-shaped frame 350, and the inside of the rubber tube 441, the inside of the circular hole and the inside of the collar 440 are all connected.

When in use, a camera module can be attached to the inside of the rubber tube 441, and the cable passing through the rubber tube 441 can be detected with the help of machine vision technology. Since the L-shaped frame 350 needs to be moved to a position close to the cable withdrawal point on the cable drum loaded with the cable, the movement path of the L-shaped frame 350 varies greatly depending on the point where the cable is withdrawn from the drum, and the ring 440 moves back and forth in sequence, so that the cable in the rubber tube 441 can be in a bent state. When the surface of the cable is bent, the damaged part on it is more obvious. In addition, being in the closed rubber tube 441 reduces external interference, thereby improving the accuracy of detection of the cable surface.

[0052] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0053] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution.
