Description

Technical Field

[0001] The invention relates to the technical field of cable trailers, in particular to a cable trailer retractable device for track running equipment. Background Art

[0002] Track running equipment refers to a type of device used to move on a specific track. Track running equipment is widely used in ports, mines, railway freight yards and other places to transport materials or perform other operations. Most of the existing track running equipment uses cables to provide the equipment with necessary conditions such as power, signal transmission or data communication. Therefore, the laying and reeling of cables plays a vital role in the installation of track equipment.

[0003] For example, Chinese patent number CN110395623A discloses a cable retracting device that is easy to transport, including a second support base, a first groove is provided on the top central outer wall of the second support base, and the inner walls at both ends of the first groove are connected to a horizontally arranged first electric guide rail by bolts, and the outer walls on both sides of the top of the two first electric guide rails are slidably connected to a first electric slider. The invention proposes a cable retracting device that is easy to transport, which is provided with a connecting rod, a roller and a first hydraulic cylinder. After the cable is retracted, the pin hole on the connecting rod can be fixed to the rear of the trailer, and the first hydraulic cylinder can be retracted so that the roller contacts the ground, and it can be directly pulled away by the trailer, achieving a very convenient transportation effect.

[0004] However, since rail travel equipment is mostly used in scenes with complex external environments such as ports and mines, cables are affected by harsh environments during use, which will greatly shorten their service life. For example, when the equipment is used in a port, the cable sheath is exposed to high-humidity salt mist, which will adsorb on the outer sheath of the cable, accelerating the corrosion of the cable sheath. The cable will be subjected to axial tension during the reeling process, which can easily cause radial cracks in the outer insulation layer. Salt will penetrate into the insulation layer along the cracks, causing further corrosion of the insulation layer. Therefore, when cables are used in these places, higher requirements are placed on the performance of the outer insulation, greatly increasing the cost of use. Summary of the invention

DETAILED DESCRIPTION

[0038] 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.

[0039] See also Figures 1 to 11 The present invention provides a technical solution: a cable retracting and releasing trolley device for a track running device, comprising a trolley 2 slidably mounted in a track 3, and further comprising:

[0040] A cable retracting device 1 installed in the trailer 2, the cable retracting device 1 is used to reel in or unreel the cable 4;

[0041] A power box 8 which is hollow inside and is mounted on the trailer 2 via a fixing frame 6, and the cable 4 passes through the power box 8;

[0042] A pre-treatment assembly and a grinding mechanism installed in the power box 8;

[0043] The pretreatment component cleans the surface of the reeled cable 4 and captures and locates the cracks on the surface of the cable 4;

[0044] The grinding mechanism is adjusted according to the crack position, and grinds the crack of the cable 4 until the crack is eliminated.

[0045] Track running equipment is also called track running machinery or track moving equipment. It is mostly used in heavy engineering projects such as handling, lifting, excavation or laying. Therefore, track running equipment is often in some harsh environments when in use. For example, when used in ports, the salt in the salt spray can penetrate into the cracks of the cable insulation layer, forming a high-concentration salt water environment, which will accelerate the chemical and physical expansion of the cracks. The salt in the salt spray will also react chemically with the cable insulation material, causing corrosion of the material and further damaging the integrity of the insulation layer. See Figure 10-11, a indicates the crack on the surface of cable 4, a1 and a2 indicate the exposed part of the insulation layer at the crack. When the salt in the salt spray adheres to the crack, it is easier to penetrate from a1 and a2 than from the outer skin, and it will also create a corrosive environment at the crack, making it easier to expand the crack;

[0046] In addition, the violent weather fluctuations and strong ultraviolet radiation at the seaside will cause the cable outer sheath to age, and the cargo transported at the port will also leak oil and chemicals, which will greatly reduce the insulation performance of the cable. Therefore, a track running device is needed to clean the salt on the surface and cracks of the cable insulation layer and repair the insulation layer. The specific implementation method is as follows:

[0047] When the device is in use, the trailer 2 needs to be connected to the main machine first, and then the cable retracting device 1 is started to unwind the cable 4 to supply power to the main machine and transmit data signals. When the main machine needs to be recovered, the cable retracting device 1 is started to rewind the cable 4. At this time, the pretreatment component in the power box 8 is started to clean the surface of the outer layer of the cable 4, and the cracks on the surface of the cable 4 are captured and located after cleaning, and then the position of the grinding mechanism is adjusted in accordance with the positioning of the cracks, so that the grinding mechanism can accurately grind the cracks of the cable 4, and completely grind and remove the a1 and a2 parts until the cracks are completely eliminated.

[0048] In this way, through the cooperation of the pretreatment component and the polishing mechanism, the salt on the surface and in the cracks of the cable 4 can be cleaned, the cracks can be eliminated, and the corrosive environment at the cracks can be eliminated, so that the salt can no longer corrode the outer insulation layer of the cable 4, and can no longer penetrate into the cracks under the action of water vapor to further corrode and damage the outer insulation layer of the cable 4, thereby increasing the service life of the cable 4, reducing the material requirements of the cable 4 in harsh environments, and greatly reducing the cost of use.

[0049] Further, the grinding mechanism includes a rotating disk 9 installed on the inner wall of the power box 8 and capable of rotating and adjusting, a slideway 19 is provided on the inner wall of the rotating disk 9, a sliding bar 15 is slidably installed in the slideway 19, an axle frame 24 is fixedly installed on the inner wall of the rotating disk 9, a rotatable rotating rod 22 is installed on the side wall of the axle frame 24, one end of the rotating rod 22 is rotatably connected to a pull rod 21, one end of the pull rod 21 is rotatably connected to one side of the sliding bar 15, a fixed column 16 is fixed to the middle of the sliding bar 15, and a grinding roller is provided on the fixed column 16;

[0050] The grinding mechanism also includes a first cylinder 12 fixed to the inner bottom wall of the rotating disk 9. The end of the power shaft of the first cylinder 12 is fixedly connected with a receiving buckle 11. The receiving buckle 11 is set in an arc shape and can axially position the cable 4.

[0051] According to the above embodiment, the cable 4 passes through the rotating disk 9 and is fixed by the receiving buckle 11. The receiving buckle 11 is driven to rotate by the rotating disk 9, so that the crack on the surface of the cable 4 rotates to just below the grinding roller, and then the first cylinder 12 is driven to drive the receiving buckle 11 and the cable 4 to move upward until the grinding roller and the crack on the surface of the cable 4 contact each other, and then the external motor is driven to drive the rotating rod 22 to rotate with the axis frame 24 as the center of the circle, and drive the pull rod 21 to make reciprocating swinging motion. The pull rod 21 also drives the sliding bar 15 to slide back and forth in the slideway 19. At this time, the grinding roller slides back and forth along the axis of the cable 4 with the sliding bar 15 at the crack on the outer surface of the cable 4 to grind the crack.

[0052] In this way, the crack position is captured or located through the pretreatment component mentioned above, and the rotating disk 9 is driven to rotate to align the crack with the grinding mechanism, and then the grinding mechanism is driven to grind the crack, so as to complete the grinding of the crack on the outer surface of the cable 4. When the salt that penetrates into the crack cannot be cleaned by the pretreatment component, the grinding component can also reprocess the salt in the crack, so that the salt cannot hide in the crack to corrode and penetrate deeper insulation layers, thereby avoiding the accelerated corrosion and physical expansion of the insulation layer by the salt in the crack.

[0053] It is worth noting that, due to the push of the first cylinder 12, only one end of the cable 4 at the crack will bulge upward to contact the grinding roller. At this time, the crack will expand under the action of the bulge, so that the grinding roller can also grind small cracks while reducing the grinding depth, thereby avoiding the grinding mechanism grinding the outer insulation layer of the cable 4 too deeply, causing the cable 4 to break or tear when it is subjected to stress.

[0054] Furthermore, the outer walls on both sides of the fixed column 16 are rotatably installed with a rotating middle rod 17 and a short rod 29 from top to bottom, and one side of the rotating middle rod 17 and the short rod 29 is rotatably connected with a rotating long rod 18. The bottom ends of the two rotating long rods 18 are fixedly installed with grinding pieces 13, and the two grinding pieces 13 are combined to form a grinding roller. The fixed column 16 is hollow inside and a second cylinder 20 is fixedly installed on the top surface of the inner wall. The power shafts of the second cylinder 20 are both rotatably installed with limit rods 28. One ends of the two limit rods 28 are respectively rotatably installed on the side walls of the centers of the two rotating long rods 18, and a sliding groove for the limit rods 28 to slide is opened in the fixed column 16.

[0055] According to the above embodiment, when the power shaft of the second cylinder 20 extends downward, the limit rod 28 is driven to rotate upward with one end of the power shaft as the center, and drives the rotating long rod 18 to move upward. When the rotating long rod 18 moves upward, it is pulled by the rotating middle rod 17 and the short rod 29, so that the rotating middle rod 17 and the short rod 29 rotate upward together with one end close to the fixed column 16 as the center, and the rotating long rod 18 moves obliquely upward at the same time. At this time, the two grinding parts 13 move obliquely upward driven by the rotating long rod 18 and gradually separate.

[0056] When the power shaft of the second cylinder 20 is retracted upward, the limit rod 28 is driven to rotate downward with one end of the power shaft as the center, and the rotating long rod 18 is driven to move obliquely upward, driving the two grinding members 13 to move obliquely downward and close to each other until the two grinding members 13 are fitted together to form a grinding roller.

[0057] In this way, by extending and retracting the active shaft of the second cylinder 20, the two grinding pieces 13 can be driven to approach each other to form a grinding roller or to move away from each other and detach from the surface of the cable 4, so as to avoid that when the cable 4 moves axially under the action of the cable retracting device 1 after grinding, the grinding piece 13 is still in contact with the surface of the cable 4, causing the grinding piece 13 to axially wear the cracked part of the insulation layer and damage the insulation layer.

[0058] Furthermore, a sliding sleeve 31 is fixedly installed on the bottom surface of the fixed column 16, and a material storage bin 25 is also opened in the fixed column 16. A piston plate 23 slidably installed in the material storage bin 25 is fixed on the bottom surface of the power shaft of the second cylinder 20. A liquid outlet pipe 26 is fixedly connected to the bottom surface of the piston plate 23. The liquid outlet pipe 26 passes through the bottom surface of the sliding sleeve 31 and is vertically downward. A through hole is opened in the piston plate 23 to enable the material storage bin 25 and the liquid outlet pipe 26 to be connected to each other, and a one-way valve is installed in the through hole, so that the material storage bin 25 is connected to an external liquid supply device.

[0059] According to the above embodiment, when the power shaft of the second cylinder 20 extends downward, it will drive the piston plate 23 to slide downward in the material storage bin 25, and drive the liquid outlet pipe 26 to extend out of the sliding sleeve 31 and slide downward. The material storage bin 25 is filled with quick-drying liquid insulating paint. At this time, the liquid insulating paint is pressed into the through hole under the action of the gas and flows into the liquid outlet pipe 26. According to the above, when the power shaft of the second cylinder 20 extends downward, it will also synchronously drive the two grinding parts 13 to separate and move obliquely upward, so that the liquid outlet pipe 26 moves downward and aligns with the smoothed cracks, so that the liquid insulating paint can be accurately sprayed onto the worn area to repair the worn insulating layer.

[0060] In this way, while the two grinding pieces 13 are driven to spread to both sides and away from the surface of the cable 4 by the second cylinder 20, the liquid outlet pipe 26 is also pushed close to the grinding area by the piston plate 23, and the grinding area is repaired by spraying paint to complete the repair of the insulation layer after grinding, so that the surface of the cable 4 can still maintain complete insulation performance after multiple grindings, thereby greatly extending the service life of the cable 4.

[0061] Furthermore, an empty slot is opened in the power box 8, and a driving gear 7 is rotatably installed in the empty slot. The driving gear 7 is meshed with the gear teeth on the outer wall of the rotating disk 9. A motor for driving the driving gear 7 to rotate is also installed in the empty slot, and the motor is connected to the pre-processing component electrical signal.

[0062] According to the above-mentioned embodiment, after the pre-processing component captures and locates the crack, it transmits the crack position to the external signal processing device through an electrical signal, and drives the motor to rotate the driving gear 7, so that the rotating disk 9 rotates together with the driving gear 7 until the crack is rotated to just below the grinding roller, and then the grinding component grinds the outer insulation layer of the cable 4.

[0063] In this way, through the cooperation between the pretreatment component and the rotating disk 9, the grinding roller can be accurately docked with the crack position, and all cracks surrounding the outer wall of the cable 4 can be ground.

[0064] Furthermore, the pretreatment component includes a connecting rod 10 fixedly mounted on the inner wall of the rotating disk 9, a cleaning device 30 is fixedly mounted on the side wall of the connecting rod 10, the cable 4 passes through the cleaning device 30, and a plurality of nozzles are annularly distributed on the inner wall of the cleaning device 30, and the nozzles are connected to an external water supply device.

[0065] According to the above embodiment, when the cable 4 passes through the cleaning device 30 under the action of the cable retracting device 1, the nozzles distributed on the inner wall of the cleaning device 30 are connected to the external water supply equipment to flush and clean the salt on the surface of the cable 4, so as to prevent the salt from accumulating on the surface of the cable 4 and corroding the outer insulation layer of the cable 4, thereby destroying the insulation properties of the insulation layer.

[0066] It is worth noting that, when the cable 4 is used in the port, it may be exposed to oil leakage from cargo or some chemicals that may corrode the outer insulation layer of the cable 4 . Therefore, a degreasing and chemical cleaning agent may be mixed into the aqueous solution in the external water supply equipment in a certain proportion to deeply clean the surface of the cable 4 , thereby further improving the cleaning effect of the cable 4 .

[0067] Furthermore, the pretreatment component also includes a dryer 27 fixedly connected to the side wall of the connecting rod 10 , the dryer 27 is located on a side close to the power box 8 , and the dryer 27 can evenly dry the surface of the cable 4 .

[0068] According to the above embodiment, it can be known that after the cable 4 passes through the cleaner 30 under the action of the cable retracting device 1, the cable 4 will enter the dryer 27, and the dryer 27 can evenly dry the surface of the cable 4. Drying can remove moisture on the surface of the insulation layer to prevent moisture from affecting the polishing quality or causing a short circuit during polishing, and the dry surface is easier to polish, and a smoother and more consistent polishing effect can be obtained. In addition, by removing moisture, the aging and performance degradation of the insulation layer of the cable 4 due to long-term moisture can be reduced.

[0069] Furthermore, the pretreatment component also includes a plurality of cameras installed on the outer wall of the dryer 27, and the cameras can capture cracks on the outer wall of the cable 4 and control the positioning and adjustment of the grinding mechanism through electrical signals.

[0070] According to the above embodiment, after the cable 4 is dried in the dryer 27, the camera installed on the outer wall of the dryer 27 can capture the cracks on the outer wall of the cable 4, and perform three-axis positioning of the crack position through the cooperation between multiple cameras. After the crack position is accurately determined, the positioning is transmitted to the grinding mechanism through an electrical signal. The grinding mechanism adjusts the crack position on this basis to facilitate the subsequent grinding of the crack.

[0071] In this way, the position of the crack can be located more accurately through the cooperation between the cameras, so that the contact between the crack and the grinding mechanism is more precise, and the unnecessary damage to the outer insulation layer of the cable 4 caused by the grinding mechanism when grinding the crack is reduced.

[0072] Furthermore, it also includes a cable reversing device 5 installed on the trailer 2, the cable 4 passes through the cable reversing device 5, and the cable reversing device 5 is arranged between the cable retracting device 1 and the power box 8.

[0073] According to the above embodiment, it can be known that by providing a cable reversing device 5 located between the cable retracting device 1 and the power box 8, the moving direction of the cable 4 can be changed and the moving direction of the cable 4 can be limited. Since the cable 4 will generate stress when bending, sharp bending exceeding a certain angle may cause damage to the insulation layer, sheath or internal conductor of the cable 4. The cable reversing device 5 can also compensate for the bending angle of the cable 4 when the cable 4 bends and turns, thereby reducing the maintenance and replacement costs caused by damage to the cable 4.

[0074] Furthermore, the trailer 2 is detachably connected to the main machine via a connecting pin 14 .

[0075] According to the above embodiment, the trailer 2 is connected to the host machine by the connecting pin 14, and the connection between the trailer 2 and the host machine can also be disconnected by the connecting pin 14 after use, so as to facilitate the use and recovery of the trailer 2.

[0076] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0077] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
