[0025] Example 1 See also Figures 1 to 6 The present invention provides a prefabricated cable overall repair and laying operation vehicle, comprising a railway flat car 1, a storage mechanism 2 for placing a prefabricated cable duct 6 is arranged in the middle of the railway flat car 1, the prefabricated cable duct 6 comprises a cable drag chain, the width of the drag chain is set according to the number of cables required in the planned repair section, the fixed-length cable drag chain on the railway bridge is selected to have a width of 500mm, which meets the fixing needs of two medium-voltage 10-35kV cables and multiple low-voltage cables, and a cable fixing hole is arranged in the drag chain, and the cable is fixed on the drag chain; Cable drag chains can be fully enclosed or bridge-type according to protection needs. For example, when considering high-voltage cables, TL155 or TL180 drag chains can be selected. When TL155 is selected, the maximum cable diameter is ≤85mm; Non-armored cables can be selected as 26 / 35kV3×70mm² three-core cross-linked polyethylene insulation, PVC / PE sheathed power cable, or 18 / 20kV3×185mm² three-core cross-linked polyethylene insulation, PVC / PE sheathed power cable; Armored cables can be selected as 18 / 20kV3×95mm² three-core cross-linked polyethylene insulation, PVC / PE sheathed armored power cable, or 8.7 / 15kV3×240mm² three-core cross-linked polyethylene insulation, PVC / PE sheathed armored power cable; When TL180 is selected, the maximum cable diameter is ≤100mm; Non-armored cables can be selected as 26 / 35kV 3×120mm² three-core cross-linked polyethylene insulation, PVC / PE sheathed power cables, or 18 / 20kV 3×300mm² three-core cross-linked polyethylene insulation, PVC / PE sheathed power cables; Armored cables can be selected as 26 / 35kV 3×95mm² three-core cross-linked polyethylene insulation, PVC / PE sheathed armored power cable, or 18 / 20kV 3×185mm² three-core cross-linked polyethylene insulation, PVC / PE sheathed armored power cable; The railway flat cars 1 located on both sides of the storage mechanism 2 are respectively provided with a generator 1-1 and a crane 1-2. The generator 1-1 is used to provide electricity for the cable trough deployment construction. The generator set adopts different types of generator sets according to the use environment. For example, when used in plateaus, a generator set specially designed for plateaus should be adopted; (the preset generator is a 30kW220 / 380V plateau type generator); A capstan 3 for pulling the prefabricated wire trough 6 is arranged on one side of the railway flat car 1 close to the crane 1-2, and a guide mechanism 4 is also arranged on the railway flat car 1 between the capstan 3 and the storage mechanism 2; The capstan 3 , the guide mechanism 4 and the storage mechanism 2 are linked via a driving mechanism 5 .

[0026] The capstan 3 comprises two wire drums 2-1 rotatably arranged on a railway flat car 1, and the cables are wound around the two wire drums 2-1; A sprocket is coaxially fixedly disposed on each wire drum 2-1, and the two sprockets are connected by a chain 2-2.

[0027] The prefabricated cable duct 6 is manufactured in the factory. Before prefabrication, the specific length of the prefabricated flexible cable duct 6 is determined according to the length of the bridge section to be repaired. The prefabricated length of the prefabricated flexible cable duct 6 should include the length of the cable head protection section at both ends and the length of the traction bracket; Prefabricated flexible cable duct 6 can be divided into two types according to needs: prefabricated flexible cable duct 6 for bridge power and prefabricated flexible cable duct 6 for bridge communication signal. Cables are directly fixed in prefabricated flexible cable duct 6 for bridge power, and cable protection tubes are fixed in prefabricated flexible cable duct 6 for bridge communication signal. First, prefabricate the cables according to the determined cable length. After the cables are cut, prefabricate the cable ends. For cables that are to be connected with cable joint boxes, prefabricate them to the shape of the cable heads before installation. For cables that need to be connected with intermediate joints, prefabricate some processes to reduce the on-site connection construction time. Cut the protective tube according to the length of the preset cable trough. The type of protective tube can be selected according to the needs. Silicon core tube or other protective tubes that can be used for cable blowing construction can be selected. When prefabricating the protective tube, traction wire can be reserved in advance to facilitate direct traction of the cable; Fix the prefabricated power cable and protective tube into the cable drag chain. The cover of the single-link chain of the cable drag chain can be opened up and down. Put the cable or protective tube into the cable drag chain and then fix it. For cable ducts 6 with protection requirements, protective plates should be installed after fixing the cables or protective tubes; If there is a single-core power cable, the fixed blank plate and protective plate should be able to prevent eddy currents and should be made of non-ferromagnetic materials such as aluminum plates; Coil the prefabricated wire duct 6 onto the wire reel 2-1. When coiling the wire duct 6, use a vertical coiling method with the side of the wire duct 6 facing down and the long side standing upright. Determine whether to use a single-coil or double-coil method for coiling according to the length of the wire duct 6. When using the double-coil method for coiling, fix one end of the wire duct 6 on one of the wire reels 2-1 and wind it around the two wire reels 2-1 in sequence to form a racetrack-shaped coiling path.

[0028] The winch 3 includes a frame. A winch roller is rotatably arranged on the frame, and a traction steel cable is wound around the winch roller. A driving worm gear is also rotatably arranged on the frame, which is coaxially fixed with the winch roller. A driving worm is also rotatably arranged on the frame, and the driving worm meshes with the driving worm gear.

[0029] On the wire duct 6 of the railway bridge, several wire guide frames should be arranged during the cable laying. Generally, one is installed every 5-10 meters. The overall shape of the guide frame is "U", and nylon guide rollers are installed inside. The wire duct 6 contacts the rollers during the traction process, which can not only be effectively constrained in the established path to prevent left-right and up-down offsets due to external interference or its own flexibility, ensuring a smooth traction direction of the cable duct, but also significantly reduce the frictional resistance by the rolling of the rollers, reduce the wear of the outer skin of the wire duct 6, and ensure a smooth traction direction of the cable duct during the traction of the flexible cable duct. An anchor point is arranged at the end of the wire duct 6 to fix the traction guide pulley group for later traction of the wire duct 6. Lay out the traction steel cable for the winch 3. The traction steel cable is led out from the winch roller fixed at the head of the work vehicle, passes through the guide pulley group, and is led to the storage area of the wire duct 6 and connected to the traction fixing head of the wire duct 6.

[0030] Use the crane 1-2 to lead the head of the wire duct 6 down from the flatbed truck, pass it through the guiding mechanism 4, and make it enter the preset traction path. Subsequently, the driving mechanism 5 realizes the traction operation of the wire duct 6. The winch roller pulls the wire duct 6 to move through the traction steel cable until the wire duct 6 is placed in place.

[0031] The guiding mechanism 4 includes two vertical plates 4-1 fixedly arranged on the railway flatcar 1. Two connecting rods 4-2 are respectively rotatably arranged on each vertical plate 4-1, and a guide 4-3 is rotatably arranged at the movable end of the connecting rod 4-2. The guide 4-3 includes a mounting seat rotatably connected to the connecting rod 4-2. Two transverse guide rollers are rotatably arranged on the mounting seat, and two longitudinal guide rollers are also rotatably arranged on the mounting seat. The wire duct 6 passes through between the transverse guide rollers and the longitudinal guide rollers.

[0032] By the swing of the connecting rod 4-2, drive the change of the horizontal height of the guide 4-3 to adapt to the position of the wire duct 6 on the wire reel 2-1 and ensure the smoothness of the operation process. Through the mutual cooperation of the transverse guide rollers and the longitudinal guide rollers, continuously correct the running direction of the wire duct 6 in two dimensions.

[0033] An output gear 4-4 is coaxially fixed on one of the connecting rods 4-2 on each vertical plate 4-1, and the output gear 4-4 is meshed with an input gear 4-5. The two input gears 4-5 are coaxially fixed through a transmission shaft 4-6; One side of the transmission shaft 4-6 extends to the outside of the vertical plate 4-1; A gear rack 4-7 is fixedly arranged on the vertical plate 4-1, and two output bevel gears 4-8 are rotatably arranged on the gear rack 4-7, and the teeth of the two output bevel gears 4-8 are opposite to each other. An input bevel gear 4-9 is also rotatably arranged on the gear rack 4-7, and the input bevel gear 4-9 is meshed with the two output bevel gears 4-8 respectively; Each output bevel gear 4-8 is meshed with an end face gear 4-10; An adapter 4-11 is slidably arranged on the transmission shaft 4-6, and a plurality of teeth are respectively arranged at the two ends of the adapter 4-11, and the teeth of the adapter 4-11 are meshed with one of the end face gears 4-10.

[0034] When the adapter 4-11 is close to one of the output bevel gears 4-8, the teeth of the adapter 4-11 mesh with the end gear 4-10 of the output bevel gear 4-8, and the input bevel gear 4-9 drives the transmission shaft 4-6 to rotate through the output bevel gear 4-8 and the adapter 4-11, and under the action of the input gear 4-5 and the output gear 4-4, the connecting rod 4-2 is swung; When the adapter 4-11 is close to another output bevel gear 4-8, the teeth of the adapter 4-11 mesh with the end gear 4-10 of the output bevel gear 4-8, and the input bevel gear 4-9 drives the transmission shaft 4-6 to rotate in the opposite direction through the output bevel gear 4-8 and the adapter 4-11. Under the action of the input gear 4-5 and the output gear 4-4, the connecting rod 4-2 is swung in the opposite direction, and this reciprocating cycle is used to change the position of the guide 4-3, so that the guide 4-3 can support the wire groove 6.

[0035] A guide groove is provided in the middle of the adapter 4-11; A swing arm 4-12 is also rotatably arranged on the gear frame 4-7, and a guide wheel is rotatably arranged on the movable end of the swing arm 4-12, and the guide wheel slides in the guide groove; A control arm 4-13 is also rotatably arranged on the gear frame 4-7, and the rotation axis of the control arm 4-13 is coaxial with the rotation axis of the swing arm 4-12; Two limit rods are fixedly arranged on the gear frame 4-7, and the two limit rods are respectively arranged on both sides of the control arm 4-13; A tension spring 4-15 is provided between the movable end of the control arm 4-13 and the movable end of the swing arm 4-12.

[0036] When the control arm 4-13 rotates to be close to one of the limit rods, under the action of the tension spring 4-15, the swing arm 4-12 is driven to rotate, and the swing arm 4-12 drives the adapter 4-11 to move onto one of the output bevel gears 4-8; When the adapter 4-11 needs to be reversed, the rotating controller moves toward another limit rod, and at this time, the tension spring 4-15 pulls and swings toward the other output bevel gear 4-8; The tension spring 4-15 can realize the coordinated action of the control arm 4-13 and the swing arm 4-12. When the control arm 4-13 rotates, it will drive the swing arm 4-12 to rotate synchronously. When there is no external interference, the tension spring 4-15 can make the adapter 4-11 always mesh with one of the end gears 4-10, realizing the uncertain transmission of force between the output bevel gear 4-8 and the adapter 4-11.

[0037] A turntable 4-16 is rotatably arranged on the vertical plate 4-1, and the turntable 4-16 is coaxial with an adjacent output gear 4-4. Two reversing rods 4-17 are fixedly arranged on the turntable 4-16, and a trigger rod 4-18 is fixedly arranged at the movable end of each reversing rod 4-17; An arc-shaped slide groove 4-19 is provided on the vertical plate 4-1, and the trigger rod 4-18 extends to the other side of the vertical plate 4-1 through the slide groove 4-19. The two trigger rods 4-18 are respectively located on both sides of one of the connecting rods 4-2; The turntable 4-16 is also connected to the joystick 4-20 by a ball joint, and the movable end of the joystick 4-20 is connected to the movable end of the control arm 4-13 by a ball joint.

[0038] When the connecting rod 4-2 swings upward, it gradually approaches the upper end of the slide slot 4-19 until the connecting rod 4-2 contacts the trigger rod 4-18. With the movement of the connecting rod 4-2, under the action of the trigger rod 4-18, the turntable 4-16 is driven to rotate clockwise by a certain angle. Under the action of the joystick 4-20, the control arm 4-13 is driven to rotate toward the side close to the vertical plate 4-1. Under the action of the tension spring 4-15 and the swing arm 4-12, the adapter 4-11 can mesh with the end gear 4-10 on the output bevel gear 4-8 close to the vertical plate 4-1 to complete the reversing operation. At this time, the connecting rod 4-2 can rotate in the opposite direction, driving the guide 4-3 to move downward. When the connecting rod 4-2 swings downward, it gradually approaches the lower end of the slide groove 4-19 until the connecting rod 4-2 contacts the trigger rod 4-18. As the connecting rod 4-2 moves, under the action of the trigger rod 4-18, the turntable 4-16 is driven to rotate counterclockwise by a certain angle. Under the action of the joystick 4-20, the control arm 4-13 is driven to rotate to the side away from the vertical plate 4-1. Under the action of the tension spring 4-15 and the swing arm 4-12, the adapter 4-11 can mesh with the end gear 4-10 on the output bevel gear 4-8 away from the vertical plate 4-1 to complete the reversing operation. At this time, the connecting rod 4-2 can rotate in the opposite direction, driving the guide 4-3 to move upward.

The input worm 5-3 and the driving worm are linked via a driving shaft 5-4; A transmission shaft is also arranged on the input worm 5-3, a rotating bevel gear is fixedly arranged on the transmission shaft, a rotating bevel gear is meshed on the rotating bevel gear, and the rotating bevel gear is coaxially fixed with one of the wire drums 2-1.

[0040] Start the drive motor 5-1, and the motor shaft of the drive motor 5-1 starts to rotate. Since the motor shaft and the drive worm are coaxially fixed, the drive worm will rotate synchronously with the motor shaft in the same direction to realize the operation of the capstan grinder 3; After the driving worm rotates, the power is transmitted to the input worm 5-3 through the driving shaft 5-4, and the input worm 5-3 drives the output worm wheel 5-2 to rotate. Under the action of the adapter 4-11 and the connecting rod 4-2, the reciprocating movement of the guide 4-3 is realized; At the same time, the transmission shaft connected to the input worm 5-3 will rotate along with the input worm 5-3, and the rotating bevel gear fixed on the transmission shaft will also rotate accordingly. The rotating bevel gear will mesh with the rotating bevel gear coaxially fixed to the wire drum 2-1. The rotating bevel gear will transmit power to the rotating bevel gear, thereby driving the wire drum 2-1 coaxial therewith to start rotating, thereby realizing the linkage of the capstan 3, the guide mechanism 4 and the storage mechanism 2.

[0041] When the present invention is used, the prefabricated wire duct 6 is coiled onto the wire drum 2-1. When the wire duct 6 is coiled, it is coiled in a vertical manner, with the side of the wire duct 6 at the bottom and the long side standing up. The single-drum or double-drum manner is determined according to the length of the wire duct 6. Anchor points are arranged at the end of the line slot 6 to fix the traction guide pulley block so as to facilitate the traction of the line slot 6 at a later stage; A traction cable is laid to pull the capstan 3 . The traction cable is led out from the capstan roller fixed on the head of the work vehicle, passes through a guide pulley block, is led to the storage area of ​​the wire trough 6 , and is connected to the traction fixed head of the wire trough 6 .

[0042] The head of the wire trough 6 is led down from the flatbed truck by crane 1-2, passed through the guide mechanism 4, and entered the preset traction path. Then the driving mechanism 5 realizes the traction operation of the wire trough 6. The grinding roller pulls the wire trough 6 to move through the traction steel cable until the wire trough 6 is put in place.
