Description

Technical Field

[0001] This invention relates to the field of cable installation technology, specifically to an anti-freeze-swell cable installation device suitable for low-temperature regions. Background Technology

[0002] Freeze-stretch-resistant cables maintain physical stability and electrical performance when used in low-temperature environments (-40℃ to -60℃), and are widely used in industrial, wind power, and rail transportation applications in cold regions. Installation requires first heating the cable to allow for proper straightening and release, and then wrapping it with an insulation layer.

[0003] In existing methods for installing frost-resistant cables, heating and insulation wrapping are performed separately. This results in the cable already being cooled to ambient temperature (-40℃ to -60℃) by the time insulation is applied. Furthermore, the cable needs to be turned over during insulation wrapping, which can easily damage it at low temperatures. Therefore, we propose an integrated frost-resistant cable installation device that combines heating and insulation wrapping. This ensures the cable remains heated during insulation wrapping, preventing damage. Summary of the Invention

[0004] The purpose of this invention is to provide an anti-freeze-swell cable installation device suitable for low-temperature areas, so as to solve the problem mentioned in the background art that the anti-freeze-swell cable drops to the ambient temperature when wrapped with insulation tape.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an anti-freeze-swell cable installation device suitable for low-temperature regions, comprising:

[0006] The vehicle body has a heating chamber and a control chamber fixedly connected to its upper side, and an insulation belt wire feeding reel movably connected to it. A cable feeding reel is movably installed inside the heating chamber.

[0007] There are two sets of cable traction wheels, symmetrically installed inside the control compartment. The cable traction wheels are rotatably connected to the control compartment wall.

[0008] The hollow winding rod has a heating function and is rotatably mounted on the outside of the control compartment. The other end of the insulation tape on the insulation tape reel is wound around the outside of the hollow winding rod, and the other end of the cable on the cable reel passes through the cable traction wheel and the center of the hollow winding rod.

[0009] The main spindle is mounted inside the control compartment, which also houses a gearbox that periodically increases and restores the spindle speed.

[0010] A dispensing machine, installed on the upper side of the vehicle body, is used to dispense adhesive onto the insulation tape wrapped around the outside of the hollow winding rod.

[0011] Both the cable traction wheel and the hollow winding rod are connected to the main shaft drive.

[0012] Preferably, the transmission includes a first fixed gear, a second fixed gear, a first speed-regulating gear, a second speed-regulating gear, an electromagnetic push rod, and a transmission shaft. The first fixed gear and the second fixed gear are coaxially arranged, and the first speed-regulating gear and the second speed-regulating gear are slidably connected to the transmission shaft. The electromagnetic push rod is used to drive the first speed-regulating gear and the second speed-regulating gear to move synchronously, and when the power is off, it drives the first speed-regulating gear to mesh with the first fixed gear; when the power is on, it drives the second speed-regulating gear to mesh with the second fixed gear.

[0013] Preferably, a transmission pulley is fitted on the outer side of the transmission shaft, and a drive pulley is fitted on the outer side of the wheel axle of the vehicle body. The transmission pulley and the drive pulley are connected by a belt.

[0014] Preferably, the inner side of the control compartment is rotatably connected to a steering adjustment shaft that is connected to the main shaft drive, and the outer side of the steering adjustment shaft is fitted with two steering bevel gears for the vehicle. The inner side of the control compartment is also rotatably connected to two directional bevel gears for driving the rotation of the cable traction wheels on both sides. The two directional bevel gears mesh with the two steering bevel gears respectively, and the two cable traction wheels rotate in opposite directions.

[0015] Preferably, the hollow winding rod includes an outer bushing rotatably connected to the outer wall of the control compartment and a hollow heating rod fixed to the wall of the control compartment. The hollow heating rod is inserted into the inner side of the outer bushing and rotatably connected to it. An installation groove is provided on the outer side of the hollow heating rod, and an electric heating wire for heating the hollow winding rod is installed on the inner side of the installation groove. The outer bushing is rotatably connected to the main shaft.

[0016] Preferably, one end of the shaft of the insulation tape feeding reel is connected to an adapter shaft, and a feeding reel drive gear is sleeved on the outer side of the adapter shaft. A feeding drive gear that meshes with the feeding reel drive gear is rotatably mounted inside the control compartment, and the shaft of the feeding drive gear is connected to the main shaft.

[0017] Preferably, the wire-feeding reel drive gear is slidably connected to the adapter shaft. A limit frame is installed inside the control compartment, and an adjusting screw is rotatably connected to the inside of the limit frame. An adjusting plate is connected to the outside of the adjusting screw via a ball nut. The adjusting plate is slidably connected to the limit frame and is used to drive the wire-feeding reel drive gear to move, so that the wire-feeding reel drive gear meshes or disengages from the wire-feeding drive gear.

[0018] Preferably, a tension plate is rotatably mounted on the outer side of the control compartment, and a guide wheel is rotatably mounted on the tension plate. The insulation tape on the insulation tape feed wheel wraps around and connects to the hollow winding rod. An adjusting shaft is connected to the rotating shaft of the tension plate on the side closest to the control compartment. A return spring is connected to the outer side of the adjusting shaft, and the other end of the return spring is connected to the wall of the control compartment. The adjusting shaft is driven by an adjusting screw.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1) This device uses a hollow winding rod to wind up the insulation tape, allowing the tape to wrap around the outside of the cable passing through the rod, thus insulating the heated cable. Simultaneously, both the cable traction wheel and the hollow winding rod for pulling the insulation tape are driven by the main shaft, ensuring synchronization between cable release and insulation tape wrapping, preventing excessive release of either the cable or the insulation tape. The gearbox periodically accelerates the main shaft speed, increasing the allowance for the cable length, thus providing sufficient slack for the cooled cable and preventing excessive tension during cable contraction.

[0021] 2) The insulation tape feed reel of this device can be selectively connected to the main shaft. The tension of the insulation tape is then detected by a tensioning plate. When the insulation tape is too loose, the feed reel disconnects from the main shaft, and the insulation tape stops releasing. When the insulation tape is too tight, the feed reel reconnects to the main shaft, releasing the insulation tape. This prevents the insulation tape from being too tight or too loose.

[0036] 70 dispensing machine. Detailed Implementation

[0037] Please see Figure 1-8 Example 1: A frost-resistant cable installation device suitable for low-temperature areas, comprising a vehicle body 11, a cable delivery reel 35, an insulation tape delivery reel 21, and a dispensing machine 70.

[0038] The vehicle body 11 has a heating chamber 12, a control chamber 13, and a power chamber 14 located on its upper part. A cable reel bracket is installed inside the heating chamber 12. The cable reel 35 is rotatably mounted on the cable reel bracket. A braking device (existing technology, not described here) is provided between the axle of the cable reel 35 and the cable reel bracket to prevent the cable reel 35 from rotating due to inertia. The heating chamber 12 heats the cable reel 35 through heat conduction, thereby heating the cable 62 wound on the cable reel 35 to approximately 15°C. The heating chamber 12 uses existing heating methods such as resistance heating or thermal combustion engine heating, which will not be described here.

[0039] A main shaft 40 and cable traction wheels 33 are rotatably mounted on the inner side of the control compartment 13. Two sets of cable traction wheels 33 are arranged side-by-side, with the cable 62 passing between them. The cable 62 is moved by the rotation of the cable traction wheels 33. A traction sprocket 341 is fitted onto the outer side of the main shaft of the cable traction wheels 33, and the traction sprockets 341 on adjacent cable traction wheels 33 in the same set are connected by a chain. A traction drive sprocket 347 is fitted onto the outer side of the main shaft 40. A steering adjustment shaft 345 is rotatably connected to the inner side of the control compartment 13. A steering bevel gear 344 and a traction driven sprocket 346 are fitted onto the outer side of the steering adjustment shaft 345, and the traction driven sprocket 346 is connected to the traction drive sprocket 347 via a chain. The control compartment 13 is also rotatably connected to a coaxially arranged transmission sprocket 342 and a directional bevel gear 343. The directional bevel gear 343 meshes with a steering bevel gear 344. The transmission sprocket 342 is connected to a traction sprocket 341 via a chain. For ease of connection, one or two traction sprockets 341 are arranged on the shaft of the same cable traction wheel 33. Each of the two sets of cable traction wheels 33 has a traction sprocket 341 connected to the transmission sprocket 342. There are also two transmission sprockets 342, two directional bevel gears 343, and two steering bevel gears 344. The two steering bevel gears 344 are symmetrically arranged and each meshes with a directional bevel gear 343, driving the two directional bevel gears 343 to rotate in opposite directions, thereby causing the two sets of cable traction wheels 33 to rotate in opposite directions. When the two sets of cable traction wheels 33 rotate, they simultaneously pull the cable 62 to move through friction.

[0040] A hollow winding rod 31 is rotatably connected to the outer wall of the control compartment 13 on the vehicle body 11. Cables 62 pass through the center of the hollow winding rod 31 and are laid out. The hollow winding rod 31 includes an outer bushing 311 and a hollow heating rod 312. The outer bushing 311 is rotatably connected to the outer wall of the control compartment 13, and a bushing driven sprocket 321 is fitted onto one end of the outer bushing 311 that extends into the control compartment 13. A bushing driving sprocket 322 is fitted onto the outer side of the main shaft 40, driving the outer bushing 311 to rotate via the main shaft 40. The surface of the outer bushing 311 is chrome-plated to improve its smoothness, thereby ensuring that the insulation tape 61 wound around the outer side of the outer bushing 311 can be easily detached. The hollow heating rod 312 is fixed to the outer wall of the control compartment 13 and is inserted into the inner side of the outer bushing 311, and is rotatably connected to the outer bushing 311. An installation groove is provided on the outer side of the hollow heating rod 312, and a heating wire 313 and a temperature sensor are installed on the inner side of the installation groove. The heating wire 313 heats the hollow winding rod 31, and the temperature sensor detects the temperature of the hollow winding rod 31, ensuring that its temperature is maintained at approximately 15°C. The cable 62 passes through the center of the hollow heating rod 312 and falls into the insulation tape 61 wrapped around the outer side of the hollow winding rod 31.

[0041] A wire feeding roller bracket is installed on the top of the vehicle body 11. A wire feeding roller 21 is rotatably mounted on the wire feeding roller bracket. A braking device is also provided between the shaft of the wire feeding roller 21 and the wire feeding roller bracket to prevent the wire feeding roller 21 from rotating due to inertia. An insulation strip 61 is wound around the outside of the wire feeding roller 21. The other end of the insulation strip 61 is wound around the outside of the hollow winding rod 31. The rotation of the hollow winding rod 31 drives the insulation strip 61 to move.

[0042] A gearbox is installed inside the control compartment 13. The gearbox includes a gearbox shaft 56, a first speed regulating gear 553, a second speed regulating gear 554, a first fixed gear 551, a second fixed gear 552, a driving bevel gear 54, a driven bevel gear 53, an electromagnetic push rod 555, and a time relay (not shown in the figure). The first fixed gear 551, the second fixed gear 552, and the driving bevel gear 54 are coaxially connected, and their shafts are rotatably connected to the inner wall of the control compartment 13. The first speed regulating gear 553 and the second speed regulating gear 554 are coaxially connected, and they are slidably sleeved on the outside of the gearbox shaft 56. The gearbox shaft 56 is rotatably connected to the inner wall of the control compartment 13, and its outer side is provided with splines. The inner side of the shafts of the first speed regulating gear 553 and the second speed regulating gear 554 is provided with spline grooves that fit the splines on the gearbox shaft 56. The electromagnetic actuator 555 is electrically connected to a time relay, which controls the actuator 555 to periodically de-energize and energize it. When the electromagnetic actuator 555 is energized, it pushes the first speed-regulating gear 553 and the second speed-regulating gear 554 to move, disengaging the first speed-regulating gear 553 from the first fixed gear 551 and engaging the second speed-regulating gear 554 with the second fixed gear 552. When the electromagnetic actuator 555 is de-energized, it pushes the first speed-regulating gear 553 and the second speed-regulating gear 554 to move, engaging the first speed-regulating gear 553 with the first fixed gear 551 and disengaging the second speed-regulating gear 554 from the second fixed gear 552. Under normal conditions, the electromagnetic actuator 555 is de-energized, the first speed-regulating gear 553 is engaged with the first fixed gear 551, and the main shaft 40 rotates at normal speed. After a period of time, the electromagnetic push rod 555 circuit is activated, and the second speed regulating gear 554 meshes with the second fixed gear 552, causing the main shaft 40 to rotate at an accelerated speed.

[0043] Driven bevel gear 53 meshes with driving bevel gear 54, and driving pulley 52 is sleeved on its shaft. Driven pulley 51 is sleeved on the outer side of main shaft 40, and driven pulley 51 and driving pulley 52 are connected by a belt. Transmission pulley 57 is sleeved on the outer side of transmission shaft 56. When wheels are installed on the vehicle body 11, drive pulley 58 is sleeved on the outer side of the wheel shaft, and transmission pulley 57 and drive pulley 58 are connected by a belt. When the vehicle body 11 is not equipped with wheels, a motor needs to be installed on the vehicle body 11, and then the motor drives drive pulley 58 to rotate.

[0044] The power compartment 14 houses a battery or generator to power the heating chamber 12, electromagnetic push rod 555, dispensing machine 70, heating wire 313, temperature sensor, and time relay. The dispensing machine 70 (existing technology, not described in detail here) is mounted on the vehicle body 11 and is used to dispense adhesive onto the insulation tape 61 on the outside of the hollow winding rod 31.

[0045] The insulation tape 61 is wound up using a hollow winding rod 31, and then glue applied to the newly wound insulation tape 61 is used to bond it. As the vehicle body 11 moves forward, the insulation tape 61, under its own weight, pulls the wound insulation tape 61 away from the hollow winding rod 31, while the cable traction wheel 33 pulls the cable 62, causing the cable 62 to pass through the wound insulation tape 61, thus protecting the cable 62. At the same time, the slightly hot hollow winding rod 31 heats the insulation tape 61, causing it to expand, which facilitates the detachment of the insulation tape 61 from the hollow winding rod 31. The gearbox periodically accelerates the rotation of the main shaft, thereby increasing the allowance for the cable 62. The cable 62 will shrink after cooling, and the allowance prevents the cable 62 from being over-tightened.

[0046] Please see Figure 1-5 Example 2 is an anti-freeze-swell cable installation device suitable for low-temperature areas. Based on Example 1, a power mechanism for driving the insulation tape pay-off wheel 21 to rotate is added. It includes a transfer shaft 241 that is detachably connected to the insulation tape pay-off wheel 21. The transfer shaft 241 is rotatably connected to the wall of the control chamber 13, and one end of the transfer shaft 241 that extends into the inside of the control chamber 13 is set as a spline shaft. A pay-off wheel transmission gear 242 is slidably connected to the outside of the spline shaft.

[0047] The inner side of the control chamber 13 is rotatably equipped with a coaxially arranged wire-feeding drive gear 243 and a wire-feeding driven sprocket 244. A wire-feeding drive sprocket 245 is sleeved on the outer side of the main shaft 40. The wire-feeding drive sprocket 245 and the wire-feeding driven sprocket 244 are driven by a chain. A limit frame is installed inside the control chamber 13. An adjusting screw 237 is rotatably connected to the inner side of the limit frame. An adjusting plate 236 is connected to the outer side of the adjusting screw 237 via a ball nut. The adjusting plate 236 is slidably connected to the limit frame. A slot is formed on the upper side of the adjusting plate 236. The wire-feeding wheel drive gear 242 is located inside the slot. The movement of the adjusting plate 236 pushes the wire-feeding wheel drive gear 242 to move. When the insulation belt 61 is tight, the wire-feeding wheel drive gear 242 meshes with the wire-feeding drive gear 243, driving the adapter shaft 241 and the insulation belt wire-feeding wheel 21 to rotate, releasing the insulation belt 61. When the insulation belt 61 is loose, the adjusting plate 236 drives the wire feeding wheel transmission gear 242, causing the wire feeding wheel transmission gear 242 to disengage from the wire feeding drive gear 243, and the adapter shaft 241 and the insulation belt wire feeding wheel 21 stop rotating.

[0048] A tension plate 22 is rotatably mounted on the outer side of the control chamber 13. A guide wheel is rotatably mounted on the tension plate 22. The insulation tape 61 on the insulation tape feed wheel 21 passes around and connects to the hollow winding rod 31. An adjusting shaft 231 is connected to the rotating shaft of the tension plate 22 on the side near the control chamber 13. A reset disc spring (not shown in the figure) is connected to the outer side of the adjusting shaft 231. The other end of the reset disc spring is connected to the wall of the control chamber 13. An adjusting drive sprocket 232 is connected to the outer side of the adjusting shaft 231. An adjusting driven sprocket 233 and a large gear 234 are rotatably mounted on the inner side of the control chamber 13. The adjusting drive sprocket 232 and the adjusting driven sprocket 233 are connected by a chain. A small gear 235 is sleeved on one end of the adjusting screw 237 that extends out of the limiting frame. The large gear 234 meshes with the small gear 235.

[0049] When the insulation belt 61 that passes over the guide wheel on the tension plate 22 is too tight, the tension on the insulation belt 61 causes the tension plate 22 to rotate. The tension plate 22 drives the large gear 234 to rotate through the adjusting shaft 231, the adjusting drive sprocket 232, and the adjusting driven sprocket 233. The large gear 234 drives the small gear 235 to rotate, which amplifies the low rotation angle of the tension plate 22. This, in turn, drives the small gear 235 and the adjusting screw 237 to rotate at a larger angle. The adjusting screw 237 rotates and drives the adjusting plate 236 to slide, which in turn drives the wire feeding wheel transmission gear 242 to move, so that the wire feeding wheel transmission gear 242 meshes with the wire feeding drive gear 243. When the insulation tape 61 passing over the guide wheel on the tension plate 22 is too loose, the reset spring causes the tension plate 22 to rotate in the opposite direction. The tension plate 22 drives the large gear 234 to rotate via the adjusting shaft 231, the adjusting drive sprocket 232, and the adjusting driven sprocket 233. The large gear 234 drives the adjusting screw 237 to rotate via the small gear 235, which in turn drives the pay-off pulley transmission gear 242 to disengage from the pay-off drive gear 243 via the adjusting plate 236. When the insulation tape 61 is too soft, the active drive of the insulation tape pay-off pulley 21 can prevent excessive tension on the insulation tape 61, thus protecting the insulation tape 61.

[0050] Working principle: Under normal conditions, the drive pulley 58 drives the transmission pulley 57 to rotate, which in turn drives the transmission shaft 56 to rotate. The first speed regulating gear 553 and the second speed regulating gear 554 rotate synchronously. The first speed regulating gear 553 drives the driving bevel gear 54 to rotate via the first fixed gear 551. The driving bevel gear 54 drives the driving pulley 52 to rotate via the driven bevel gear 53. The driving pulley 52 drives the main shaft 40 to rotate via the driven pulley 51. After a period of time, the time relay activates the circuit of the electromagnetic push rod 555. The electromagnetic push rod 555 pushes the first speed regulating gear 553 and the second speed regulating gear 554 to move, disengaging the first speed regulating gear 553 from the first fixed gear 551 and engaging the second speed regulating gear 554 with the second fixed gear 552. At this time, the second speed regulating gear 554 drives the second fixed gear 552 to rotate. The second fixed gear 552 drives the main shaft 40 to rotate faster through the driving bevel gear 54, driven bevel gear 53, driving pulley 52 and driven pulley 51. The time relay disconnects the circuit of the electromagnetic push rod 555. The electromagnetic push rod 555 pushes the first speed regulating gear 553 and the second speed regulating gear 554 to return to their original positions.

[0051] The main shaft 40 drives the driven sprocket 346 to rotate via the driving sprocket 347. The driven sprocket 346 drives two steering bevel gears 344 to rotate synchronously via the steering adjustment shaft 345. The two steering bevel gears 344 drive two directional bevel gears 343 to rotate in opposite directions at the same speed. The two directional bevel gears 343 drive the traction sprockets 341 on the two sets of cable traction wheels 33 to rotate in opposite directions at the same speed via the transmission sprocket 342. This, in turn, drives the two sets of cable traction wheels 33 to rotate in opposite directions at the same speed. The cable traction wheels 33 pull the cable 62 toward the hollow winding rod 31 by friction.

[0052] The main shaft 40 drives the driven sprocket 321 of the bushing to rotate via the driven sprocket 322 of the bushing. The driven sprocket 321 of the bushing rotates via the outer bushing 311, and the outer bushing 311 winds up the insulation tape 61 by rotating. At the same time, the glue dispensing machine 70 applies glue to the outside of the wound insulation tape 61 to bond the wound insulation tape 61 together.

[0053] During operation, the insulation tape 61 is first wrapped around the outer bushing 311 for initial adhesion. Then, the cable 62 extending from the hollow heating rod 312 and the insulation tape 61 manually pulled out from the outer bushing 311 are fixed. Then, the vehicle body 11 is moved. Initially, the insulation tape 61 at the fixed end pulls the insulation tape 61 on the outer bushing 311. After a period of time, a sufficient amount of insulation tape 61 and cable are released. Under their own weight, they will pull the insulation tape 61 on the outer bushing 311, so that the insulation tape 61 gradually detaches from the outer bushing 311.
