Description

Technical Field

[0001] The invention belongs to the technical field of wiring equipment, and in particular relates to a wiring device for a railway transportation communication room. Background Art

[0002] With the rapid development of railway transportation, the railway communication system, as an important part to ensure the safe and efficient operation of trains, has received great attention for its stability and reliability. The railway communication room is the core link of the railway communication system, responsible for handling a large amount of data exchange and signal transmission tasks. In these rooms, the wiring device is a key component connecting various communication equipment and transmission lines, and its performance directly affects the operating efficiency and stability of the entire communication system.

[0003] However, in the prior art, there is a common problem in the process of wiring in railway transportation communication rooms: due to the large number of cables and the fact that the cables are almost the same color, construction workers or maintenance personnel cannot quickly identify the direction of the cables when checking the connectors at both ends of the cables. This not only increases the difficulty of construction and maintenance, but also reduces work efficiency and may even lead to incorrect wiring operations, affecting the normal operation of the communication system.

[0050] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0051] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0052] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0053] Please refer to the attached Figures 1 to 3 as well as Fig.12 As shown, it is the first embodiment of the present invention, which provides a wiring device for railway traffic communication room, including a bracket 100, a substrate 101 is fixed to one side of the inside of the bracket 100, a flange plate 102 is fixed to one side of the bracket 100, and further includes:

[0054] A plurality of marking pens 103, wherein the plurality of marking pens 103 are distributed in a fan-shaped manner inside the bracket 100;

[0055] A line drawing mechanism 200, which is mounted on one side of the substrate 101;

[0056] The transmission mechanism 300 is mounted on one side of the substrate 101 and is connected to the line drawing mechanism 200;

[0057] A plurality of adjustment mechanisms 400, each of which is mounted on the marking mechanism 200, and each of which corresponds to each of the plurality of marking pens 103. The adjustment mechanisms 400 can adjust the position of the marking pens 103 relative to the transmission sleeve 205;

[0058] A tensioning mechanism 500, which is mounted on one side of the substrate 101 and can limit the position of the cable in a wound state;

[0059] Among them, one end of the cable is passed through the drawing mechanism 200 and the transmission mechanism 300 in turn, and the end of the cable is pulled. The drawing mechanism 200 and the transmission mechanism 300 are driven by the cable to operate, and the adjustment mechanism 400 and multiple marking pens 103 are driven to rotate around the cable. The multiple marking pens 103 draw spiral marks on the surface of the cable.

[0060] It should be noted that the cables are in a coiled state when they leave the factory, and a cable reel or through hole is provided inside the cable reel.

[0061] Furthermore, the interior of the marker pen 103 is injected with colored ink. When the color of the spiral mark needs to be changed, the marker pen 103 of the corresponding color can be replaced. Preferably, in this embodiment, the ink injected into the interior of the marker pen 103 is quick-drying oily ink.

[0062] In this embodiment, when performing wiring operations in a railway transportation communication room, the cable reel is sleeved on the outside of the tensioning mechanism 500, the tensioning mechanism 500 is operated, the cable reel is limited by the tensioning mechanism 500, one end of the cable is passed through the drawing mechanism 200 and the transmission mechanism 300 in sequence, the position of the marker 103 is adjusted by the adjustment mechanism 400, the number and color of the marker 103 are adjusted as needed, so that the pen head of the marker 103 fits the cable, the cable is pulled, and wiring construction is carried out. When the construction personnel pull the cable, the cable drives the drawing mechanism 200 and the transmission mechanism 300 to operate, and the transmission mechanism 300 drives the The adjusting mechanism 400 and the marking pen 103 rotate around the cable, so that the marking pen 103 makes a spiral motion relative to the cable, and then the marking pen 103 draws a spiral mark on the surface of the cable. After the wiring is completed, even if the cable in the cabinet is twisted or partially covered, the spiral mark on the cable surface will not be completely covered. The construction personnel or maintenance personnel can still quickly identify the direction of the cable and the communication equipment connected to both ends of the cable by the color and number of the spiral mark on the cable surface, avoiding the situation where the mark fails due to cable twisting or partial obstruction (that is, the mark cannot be identified or observed, resulting in the phenomenon that the mark loses its function).

[0063] It should be noted that the color of the marker 103 refers to the color of the line written by the marker 103. Preferably, in the present embodiment, the color of the surface of the marker 103 is the same as the color of the written line, so that construction personnel can find the marker 103 of the corresponding color. At the same time, by adjusting the number and color of the marker 103, different spiral line marks can be engraved on the cable surface. For example, when there are 2 spiral line marks, the color can be: black + black, red + red, black + red or other color combinations; when there are 4 spiral line marks, the color can be: 4 black, 3 black + red, 2 black + 2 red, etc. By adjusting the number and color of the marker 103, markings of different colors and quantities can be achieved, which is convenient for construction personnel or maintenance personnel to distinguish and identify.

[0064] Next, please refer to Figures 3 to 5 The line drawing mechanism 200 includes a bottom plate 201, a first driving roller 202, a second driving roller 203, a plurality of driven guide rollers 204, a transmission sleeve 205, a plurality of guide tubes 206, a plurality of roller shafts 207, a plurality of supporting rollers 208, a plurality of first elastic elements 209 and a plurality of extension arms 210. The bottom plate 201 is fixed to one side of the substrate 101. The first driving roller 202, the second driving roller 203 and the plurality of driven guide rollers 204 are rotatably connected to one end of the bottom plate 201 through a ball bearing. The first driving roller 202, the second driving roller 203 and the plurality of driven guide rollers 204 are distributed in a circular shape. The first driving roller 202 and the transmission mechanism 300 are connected to each other as are the second driving roller 203 and the transmission mechanism 300. The first driving roller 202, The second driving roller 203 and the plurality of driven guide rollers 204 constitute a circular guide rail mechanism, the transmission sleeve 205 is rollingly connected inside the circular guide rail mechanism, and the transmission sleeve 205 is connected to the adjustment mechanism 400, the plurality of guide tubes 206 are all tilted and fixed inside the transmission sleeve 205, the plurality of roller shafts 207 are respectively slidably connected to the upper ends of the plurality of guide tubes 206, the plurality of support rollers 208 are respectively rotationally connected to the upper ends inside the plurality of roller shafts 207, and the support rollers 208 are adapted to the marker 103, the plurality of first elastic elements 209 are assembled between the connected guide tubes 206 and the roller shafts 207, the plurality of extension arms 210 are respectively fixed to the upper ends and the lower ends of the extension arms 210, wherein, in the initial state, the first elastic element 209 is in a compressed state;

[0065] It should be noted that, in this embodiment, there is at least one transmission sleeve 205 between the second driving roller 203 and the driven guide roller 204 .

[0066] In this embodiment, when wiring is performed in a railway transportation communication room, the cable reel is positioned by the tensioning mechanism 500, one end of the cable is passed through the interior of the circular guide mechanism and the interior of the transmission mechanism 300, and the surface of the cable is fitted with the support roller 208. According to the marking requirements, the number and color of the marker 103 are adjusted, and the adjustment mechanism 400 is operated so that the pen tip of the marker 103 fits the surface of the cable. The cable can be supported by the cooperation of multiple support rollers 208 to avoid the marker 103 from deviating when marking on the cable surface, resulting in the marker 103 being unable to mark on the cable surface. The cable is pulled, and the transmission mechanism 300 is driven to operate through the cable. Due to the first drive roller 202 and the transmission mechanism 3 00 and the second driving roller 203 are connected to the transmission mechanism 300, and the first driving roller 202 and the second driving roller 203 are driven to rotate synchronously through the transmission mechanism 300. Since the transmission sleeve 205 is assembled inside the circular guide rail mechanism, the transmission sleeve 205 is driven to rotate through the cooperation of the first driving roller 202 and the second driving roller 203, and the guide tube 206, the adjustment mechanism 400 and the marking pen 103 are driven to rotate around the cable through the transmission sleeve 205. Since the marking pen 103 moves along the axial direction of the transmission sleeve 205, the marking pen 103 makes a spiral motion relative to the cable, and then the spiral line mark is engraved on the surface of the cable through the marking pen 103, thereby avoiding the marking failure caused by cable twisting or partial obstruction.

[0067] Secondly, please refer to Figure 5 As shown, the guide tube 206 is internally slidably connected with a guide rod 211, the guide rod 211 and the roller shaft 207 are fixedly connected, the guide tube 206 and the roller shaft 207 are slidably connected via the guide rod 211, a chamfered surface is provided on the outer side of the guide rod 211, a stop surface is provided at one end of the guide tube 206, and the chamfered surface and the stop surface are matched.

[0068] In this embodiment, the guide rod 211 can guide the roller shaft 207 when the roller shaft 207 slides relative to the guide tube 206, thereby preventing the roller shaft 207 from rotating and causing the relative angle between the supporting roller 208 and the cable to change.

[0069] In a preferred embodiment, a rubber ring is disposed on the outer side of the supporting roller 208, and a plurality of anti-slip grooves are formed on the outer side of the rubber ring.

[0070] In this embodiment, the provision of the rubber ring can prevent the support roller 208 from crushing the cable surface.

[0071] Please refer again Figure 6 and Figure 7The transmission mechanism 300 includes a frame 301, a first shaft 302, a first bevel gear 303, a first transmission roller 304, a second transmission roller 305, a second elastic element 306, a second shaft 307, a second bevel gear 308, a first pulley 309, a second pulley 310, a third pulley 311, a first transmission belt 312 and a second transmission belt 313. The frame 301 is fixed to an end of the extension arm 210 away from the base plate 201. The first shaft 302 is rotatably connected to the inside of the frame 301 through a ball bearing, and the first shaft 302 and the base plate 101 are rotatably connected through a ball bearing. The first bevel gear 303 and the first transmission roller 304 are both fixed to the outside of the first shaft 302, and the first transmission roller 304 is located inside the frame 301. The second transmission roller 305 is slidably connected to the lower end of the inside of the frame 301. The second elastic element 306 is assembled between the frame 301 and the second transmission roller 305, and the second elastic element 306 is located at the lower end of the frame 301, the second shaft 307 is rotatably connected to the inside of the flange plate 102 through a ball bearing, and the second shaft 307 and the base plate 201 are rotatably connected through a ball bearing, the second bevel gear 308 is fixed to one end of the outer side of the second shaft 307, and the first bevel gear 303 and the second bevel gear 308 are meshed and connected, the first pulley 309 is fixed to the other end of the outer side of the second shaft 307, the second pulley 310 is fixed to one end of the first driving roller 202, the third pulley 311 is fixed to one end of the second driving roller 203, the first transmission belt 312 is assembled on the outer sides of the first pulley 309 and the second pulley 310, and the second transmission belt 313 is assembled on the outer sides of the first pulley 309 and the third pulley 311.

[0072] It should be noted that a T-shaped limit rod is provided at the lower end of the second transmission roller 305, and the second transmission roller 305 and the frame 301 are slidably connected through the T-shaped limit rod. A limiting surface is provided on the outer side of the T-shaped limit rod, and the limiting surface can prevent the T-shaped limit rod from rotating relative to the frame 301. In the initial state, the second elastic element 306 is in a compressed state, and the second transmission roller 305 and the first transmission roller 304 are in contact with each other. After the cable passes between the first transmission roller 304 and the second transmission roller 305, under the drive of the second elastic element 306, the cable of the first transmission roller 304 and the cable of the second transmission roller 305 are in close contact with each other.

[0073] Furthermore, rubber anti-skid sleeves are provided on the outer sides of the first transmission roller 304 and the second transmission roller 305 . The provision of the rubber anti-skid sleeves can increase the friction between the cable and the first transmission roller 304 and between the cable and the second transmission roller 305 .

[0074] In this embodiment, when wiring the railway transportation communication room, the cable reel is positioned by the tensioning mechanism 500, one end of the cable is passed through the interior of the circular guide mechanism and between the first transmission roller 304 and the second transmission roller 305, the number and color of the marker 103 are adjusted so that the pen tip of the marker 103 fits the surface of the cable. When wiring, the construction personnel pull the end of the cable to move the cable. Since the first transmission roller 304 and the cable and the second transmission roller 305 and the cable are tightly fitted, the first transmission roller 304 is driven to rotate by the cable, and the first transmission roller 304 and the first shaft 302 are fixedly connected, and the first shaft 302 and the first bevel gear are connected. The first transmission roller 304 drives the first shaft 302, the first bevel gear 303 and the second bevel gear 308 to rotate due to the fixed connection between the first bevel gear 303 and the meshing connection between the first bevel gear 303 and the second bevel gear 308. Since the second bevel gear 308 and the second shaft 307 and the second shaft 307 and the first pulley 309 are all fixedly connected, the second bevel gear 308 drives the second shaft 307 and the first pulley 309 to rotate synchronously, and then drives the second pulley 310 and the third pulley 311 to rotate through the first pulley 309. Since the second pulley 310 and the first driving roller 202 and the third pulley 311 and the second driving roller 203 are all fixedly connected. The first drive roller 202 and the second drive roller 203 are driven to rotate by the second pulley 310 and the third pulley 311, respectively, so that the transmission sleeve 205 is driven to rotate by the first drive roller 202 and the second drive roller 203, so that the transmission sleeve 205 drives the adjustment mechanism 400 and the marking pen 103 to rotate around the cable, and the marking pen 103 is used to mark a spiral line on the surface of the cable. Through the above-mentioned scheme, the speed at which the construction personnel pull the cable is proportional to the speed at which the marking pen 103 marks the spiral line (that is, the faster the construction personnel pull the cable, the faster the rotating speed of the marking pen 103, and the faster the marking pen 103 marks the spiral line on the cable surface. On the contrary, the slower the speed at which the construction workers pull the cable, the slower the speed of the marker pen 103 rotates, and the slower the speed at which the marker pen 103 marks the spiral line on the cable surface). At the same time, the operation of the marking mechanism 200 and the transmission mechanism 300 does not require additional driving elements. The transmission mechanism 300 can convert the pulling force of the construction workers pulling the cable into the driving force of the marking mechanism 200. The drawing mechanism 200 and the transmission mechanism 300 can be driven to rotate by relying on the pulling force when the construction workers pull the cable. At the same time, the speed at which the marker pen 103 draws the spiral line mark can be synchronized with the speed of pulling the cable, so that the pitch of the spiral line mark drawn on the cable surface can always be the same, and the spiral line mark is more beautiful.

[0075] Please refer again Figure 8 and Fig. 9As shown, the adjustment mechanism 400 includes a threaded adjustment tube 401 and a locking threaded cap 402. The threaded adjustment tube 401 is threadedly connected to the side wall of the base plate 201. A plurality of locking holes 403 are provided at the upper end of the threaded adjustment tube 401. A first external thread 404 and a second external thread 405 are provided at the outer side of the threaded adjustment tube 401. The locking hole 403 is located at the upper end of the first external thread 404. The locking threaded cap 402 is threadedly connected to the outer side of the threaded adjustment tube 401 through the locking hole 403. When the locking threaded cap 402 is rotated to move toward the direction close to the first external thread 404, the locking threaded cap 402 can clamp the marker 103.

[0076] Furthermore, the outer diameter of the first external thread 404 is greater than the outer diameter of the second external thread 405 .

[0077] It should be noted that the inner wall of the locking thread cap 402 and the vertical cross-section shape of the second external thread 405 are both trapezoidal. When the locking thread cap 402 is rotated to move toward the direction close to the first external thread 404, the locking thread cap 402 can squeeze the upper end of the threaded adjustment tube 401, thereby limiting the locking door 403 located inside it.

[0078] In this embodiment, the cable is passed through the marking mechanism 200 and the transmission mechanism 300, and the marker pen 103 of the appropriate color is replaced according to the wiring requirements, and the marker pen 103 is inserted into the threaded adjustment tube 401 so that the pen tip of the marker pen 103 fits the cable, and the locking thread cap 402 is rotated to move the locking thread cap 402 toward the direction close to the first external thread 404. The locking thread cap 402 and the threaded adjustment tube 401 cooperate to limit the marker pen 103, and the cable can be pulled to allow the marker pen 103 to draw a spiral mark on the cable surface; when it is necessary to adjust the spiral mark on the cable surface When the number of spiral line marks is adjusted, the threaded adjustment tube 401 is rotated, and the threaded adjustment tube 401 and the transmission sleeve 205 are threadedly connected to make the threaded adjustment tube 401 move relative to the transmission sleeve 205, and then the threaded adjustment tube 401 drives the marking pen 103 inside it to move. When the marking pen 103 and the cable are separated, the purpose of adjusting the number of spiral line marks can be achieved. Through the above-mentioned scheme, the position of the marking pen 103 can be adjusted by rotating the threaded adjustment tube 401, and then the number and color of the spiral lines on the cable surface can be quickly adjusted, so that construction personnel can quickly distinguish different cables.

[0079] Please refer again Figure 10 to Figure 11The tensioning mechanism 500 includes a tensioning shaft 501, a first slider 502, a second slider 503, a positioning sleeve 504, a guide rod 505, a plurality of positioning rings 506, a plurality of rotating arms 507 and a plurality of supporting arms 508. The tensioning shaft 501 is rotatably connected to the inside of the base plate 101 through a ball bearing. Two male threads are provided on the outer side of the tensioning shaft 501, and the thread rotation directions of the two male threads are opposite. The first slider 502 and the second slider 503 are respectively threadedly connected to the outer sides of the two male threads. The positioning sleeve 504 and the guide rod 505 are rotatably connected to the outer side of the tensioning shaft 501. And they are respectively located at one end of the two male threads away from each other, a plurality of positioning rings 506 are fixed between the positioning sleeve 504 and the guide rod 505, and the first slider 502 and the positioning ring 506 as well as the second slider 503 and the positioning ring 506 are all slidingly connected, a plurality of rotating arms 507 are respectively rotationally connected to the outside of the first slider 502 and the second slider 503, and there is a one-to-one correspondence between the plurality of rotating arms 507 located on the outside of the first slider 502 and the plurality of rotating arms 507 located on the outside of the second slider 503, and the support arm 508 is rotationally connected between the two corresponding rotating arms 507.

[0080] In this embodiment, the cable roll is sleeved on the outside of the plurality of support arms 508, and the positioning sleeve 504 is held so that the positioning sleeve 504 remains stationary. Since the positioning sleeve 504 and the positioning ring 506 as well as the guide rod 505 and the positioning ring 506 are all fixedly connected, the guide rod 505 and the positioning ring 506 are kept stationary through the positioning sleeve 504, and the tensioning shaft 501 is rotated. Through the threaded connection between the tensioning shaft 501 and the first slider 502 and the tensioning shaft 501 and the second slider 503, the tensioning shaft 501 drives the first slider 502 and the second slider 503 to move in opposite directions. The rotational connection between the second slider 503 and the rotating arm 507 enables the first slider 502 and the second slider 503 to drive the rotating arm 507 to rotate. When the angle between the rotating arm 507 and the tensioning shaft 501 gradually increases, the multiple support arms 508 move in directions away from each other. Through the cooperation of the multiple support arms 508, the cables sleeved on the outside of the support arms 508 can be supported and limited. Conversely, when the angle between the rotating arm 507 and the tensioning shaft 501 gradually decreases, the multiple support arms 508 move in directions approaching each other, thereby releasing the support and limitation of the cables formed by the multiple support arms 508, so that the device can support and limit cable rolls with different apertures.

[0082] In this embodiment, the provision of the hand wheel 509 and the handle facilitates increasing the friction between the construction worker's hand and the hand wheel 509 and the handle, making it easier for the construction worker to apply force.

[0083] The working principle of the present invention is:

[0084] When performing wiring operations in a railway transportation communication room, the cable roll is sleeved on the outside of the support arm 508, the positioning sleeve 504 is held still, and the hand wheel 509 is turned to form a support limit for the cable roll through the cooperation of multiple support arms 508. One end of the cable is passed through the line drawing mechanism 200 and the transmission mechanism 300 in turn, and the cable is pulled. The first transmission roller 304 and the second transmission roller 305 are driven to rotate through the cable, so that the transmission mechanism 300 operates, and the tension applied to the cable is transmitted to the line drawing mechanism through the transmission mechanism 300. 200, and drives the marking mechanism 200 to operate, so that the circular guide mechanism drives the transmission sleeve 205, the adjustment mechanism 400 and the marking pen 103 to rotate around the cable, and the spiral line mark is carved on the cable surface by the marking pen 103. After the wiring is completed, even if the cable in the cabinet is twisted or partially covered, the spiral line mark on the cable surface will not be completely covered. The construction personnel or maintenance personnel can still quickly identify the direction of the cable and the communication equipment connected at both ends of the cable through the color and number of the spiral line marks on the cable surface.
