Description

Technical Field

[0001] The present application relates to the technical field of power cables, and in particular to a railway power cable laying device. Background Art

[0002] Cable laying is a vital task in railway construction and daily maintenance. Cable pay-off racks are indispensable equipment in the cable laying process. They are mainly used to support the handling, placement, and maintenance of cables or optical cables, ensuring that the cables can move smoothly and safely during the laying process, so that they can be accurately installed and transported to the designated location.

[0003] However, the existing cable retracting rack is prone to excessive rotation and rotation during the cable release process. First, when the cable is pulled out from the cable drum, the cable drum may continue to rotate due to inertia or external force. Second, when the cable encounters obstacles or the tension suddenly increases during the release process, the cable will produce a reverse pulling force on the reel, causing the reel to rotate. The above situation will cause the cable outside the cable drum to be too loose. At the same time, this loose state not only affects the aesthetics and neatness of the cable laying, but more importantly, the overly loose cable is easy to fall off and entangled on the cable drum and the drag shaft, forming a chaotic cable pile.

[0004] Workers have to frequently tidy up scattered cables, which not only increases their workload but also seriously affects the efficiency of cable laying.

[0005] In view of the above problems, a railway power cable pay-out device is now designed. Utility Model Content

The elastic component is arranged on the side of the baffle away from the frame. The other end of the elastic component is arranged inside the mounting groove. The positioning protrusion is arranged inside the lead groove and is used to limit the baffle.

[0013] Some embodiments further include a guide wheel mechanism, the guide wheel mechanism including two mounting plates and two guide rollers, the two mounting plates being arranged on the cart opposite to each other and being located between the frame and the lead stage;

[0014] The two guide rollers are relatively rotatable and arranged between the two mounting plates, and a cable threading opening is formed between the two guide rollers.

[0015] In some embodiments, the elastic component is a spring.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0028] An embodiment of the present application provides a railway power cable pay-out device, which can solve the problem in the related art that the existing cable retracting and paying-out rack is prone to excessive rotation and swivel during the cable paying-out process, causing the cable outside the cable reel to be too loose, making the cable easily fall off and entangled on the cable reel and the towing shaft.

[0029] See also Figure 1-Figure 3A railway power cable pay-off device comprises: a frame 1, a lead-in platform 3 and a plurality of one-way conveying mechanisms 5, wherein the frame 1 is provided with two sets of rotating seats 2 for supporting the rotation of the cable drum; the lead-in platform 3 is provided with a plurality of lead-in grooves 4 for guiding the cable pay-off; the lead-in grooves 4 are relatively provided with mounting grooves 6 for accommodating the one-way conveying mechanism 5; the one-way conveying mechanism 5 comprises a set of rotating shafts 51, a set of baffles 52, an elastic component 53 and a set of positioning protrusions 54, a set of the rotating shafts 51 is arranged in the corresponding mounting grooves 6, the baffles 52 are rotatably arranged on the rotating shafts 51, and two adjacent baffles 52 are arranged in a V shape, the elastic component 53 is arranged on the side of the baffle 52 away from the frame 1, and the other end of the elastic component 53 is arranged in the mounting groove 6, and the positioning protrusion 54 is arranged in the lead-in groove 4 and is used to limit the baffle 52.

[0030] In actual operation, the cable drum is placed on the rotating seat 2 on the frame 1 so that it can rotate freely.

[0031] When the cable starts to be released, the cable will be released from the cable drum and pass through the lead groove 4 on the lead platform 3. Inside the lead groove 4, the baffle 52 is rotated in the installation groove 6 by the rotating shaft 51. The two adjacent baffles 52 are arranged in a V shape. This design makes the cable only move in a fixed direction when passing through. When the cable enters from the V-shaped opening, due to the elasticity of the elastic component 53, the cable can push the baffle 52 to expand outward and pass smoothly. When the cable tries to move in the opposite direction, the baffle 52 returns to its original state under the action of the elastic component 53, forming an obstacle to prevent the cable from moving in the opposite direction. The positioning protrusion 54 is arranged inside the lead groove 4 to limit the rotation range of the baffle 52 and ensure that the baffle 52 can stably remain in the V-shaped state.

[0032] That is to say, when the staff stops pulling the cable, the tension on the cable will quickly disappear. At this moment, the baffle 52, which was originally expanded outward due to the cable tension, loses the force of the cable. At this time, the elastic component 53 begins to play its role. It pushes the baffle 52 to return to its original position, that is, to the tight V-shaped state. This recovery action allows the baffle 52 to re-form an obstacle to the cable, effectively preventing the cable from moving in the opposite direction. Due to the close arrangement of the baffles 52 and the reset force of the elastic component 53, the cable is locked in its current position and cannot retreat. At the same time, the rotation of the cable drum is also restricted. Since the cable is locked in the pay-off device, the cable drum loses the power to continue rotating, so it will not continue to rotate. This design ensures that the cable drum can remain stable when there is no need to pay-off, and avoids the phenomenon of cable drum rotation caused by inertia or external force.

[0033] To sum up, when the staff stops pulling the cable, the railway power cable unwinding device locks the cable and restricts the rotation of the cable drum through the coordinated action of the baffle 52 and the elastic component 53 in its one-way conveying mechanism, thereby avoiding rotation and excessive rotation of the cable during unwinding, preventing loose cables from falling off and getting entangled on the cable drum and the tow shaft, ensuring the stability and safety of the cable during unwinding, improving the work efficiency of cable laying, and reducing potential problems caused by cable rotation.

[0034] It can be understood that the distance between the lead-in platform 3 and the rotating base 2 in this embodiment is one third or one fifth of the diameter of the cable drum.

[0035] Specifically, when the cable reel is subjected to a large inertia, although it may still rotate a certain distance, since the distance between the lead-in platform 3 and the rotating seat 2 is much smaller than the diameter of the cable reel, even if the cable reel continues to rotate after the cable is locked, the length of the released cable is limited. This limited length of cable will still be wound around the cable reel and will not fall off outside the cable reel, thereby avoiding the problem of the cable being entangled outside.

[0036] This design not only reduces the risk of cable entanglement, but also improves the efficiency and safety of cable laying.

[0037] Preferably, Figure 4 As shown, in this embodiment, two adjacent baffles 52 are provided with V-shaped limiting grooves 521 on one side close to the frame 1 .

[0038] The existence of the V-shaped limiting groove 521 further strengthens the guiding and positioning function of the baffle 52 when it is acted upon by the cable.

[0039] Specifically, when the cable passes through the baffle 52, it moves along the guiding direction of the V-shaped limiting groove 521, which makes the movement of the cable smoother and also helps prevent the cable from being offset or stuck during transportation.

[0040] At the same time, the design of the V-shaped limit groove 521 makes its opening width slightly smaller than the diameter of the cable. In this way, when the cable is placed in the V-shaped limit groove 521, its two sides will be clamped to a certain extent. This clamping effect not only helps to maintain the stability of the cable during transportation and prevent it from shaking or shifting, but also effectively prevents the cable from moving in the opposite direction when the force is lost.

[0041] Specifically, when the cable stops moving, the baffle 52 will try to return to its original position due to the restoring force of the elastic component 53. At this time, the clamping effect of the V-shaped limit groove 521 will be more obvious. It will fit tightly on both sides of the cable to form an effective obstacle to prevent the cable from moving in the opposite direction.

[0042] This design not only enhances the locking effect of the one-way conveying mechanism 5, so that the cable can be firmly fixed in place when it stops moving forward, but also improves the safety and reliability of the entire device.

[0043] Preferably, the present embodiment also includes a guide wheel mechanism 10, and the guide wheel mechanism 10 includes two mounting plates 11 and two guide rollers 12, the two mounting plates 11 are relatively arranged on the cart 8, and are located between the frame 1 and the lead-in platform 3; the two guide rollers 12 are relatively rotatably arranged between the two mounting plates 11, and the two guide rollers 12 enclose a cable threading opening.

[0044] The cable passes through the cable threading opening between the two guide rollers 12, so that the moving track of the cable can be limited.

[0045] Moreover, in actual operation, when the inertia of the cable reel is too large, after the cable is locked by the one-way conveying mechanism 5, the cable reel will rotate a certain distance under the action of inertia. Due to the obstruction of the two guide rollers 12, the bent cable will abut against the guide rollers 12, thereby offsetting the inertia of the cable and effectively preventing the cable from falling off the outside of the cable reel.

[0046] Furthermore, in this embodiment, the elastic component 53 is a spring.

[0047] As a common elastic element, the spring has the advantages of simple structure, good elasticity and high reliability, and is therefore very suitable as the elastic component in the device.

[0048] Specifically, one end of the spring is connected to the side of the baffle 52 away from the frame 1, and the other end is fixed inside the mounting groove 6. When the cable passes through the baffle 52, the spring is compressed, allowing the baffle 52 to expand outward to accommodate the passage of the cable. When the cable stops moving forward or attempts to move in the reverse direction, the spring uses its restoring force to push the baffle 52 back to its original position, clamping the cable to prevent it from moving in the reverse direction.

[0049] In addition, the elasticity of the spring can be adjusted according to actual needs to adapt to cables of different diameters. This makes the device highly versatile and flexible and can adapt to various cable laying scenarios.

[0050] This embodiment further includes a trolley 8 , on which the rack 1 and the lead stage 3 are both arranged.

[0051] The cart 8 serves as a mobile carrier for the entire device. The frame 1 and the lead platform 3 are both arranged on the cart 8, so that the entire wire-paying device has good portability and mobility, thereby adapting to the needs of different work scenes. Specifically, the cart 8 allows the staff to easily move the wire-paying device to the desired work location.

[0052] As a preferred embodiment, the present implementation method also includes a fastening mechanism 9, which includes two positioning rods 91 and a pressure plate 92. The two positioning rods 91 are relatively arranged at both ends of the lead stage 3, and the pressure plate 92 is inserted above the two positioning rods 91 and is used to close the lead groove 4; a plurality of arc grooves matching the lead groove 4 are opened at the bottom of the pressure plate 92.

[0053] The two positioning rods 91 are relatively arranged at the two ends of the lead platform 3, providing a stable support and guiding structure for the pressure plate 92. The pressure plate 92 can be inserted above the two positioning rods 91 and can slide or be fixed along the direction of the positioning rods 91. This design enables the pressure plate 92 to be easily adjusted to adapt to cables of different diameters and quantities.

[0054] When the cable is placed in the lead trough 4, the pressure plate 92 is placed above the cable and fixed to the positioning rod 91 by some fastening mechanism such as bolts, clips, etc. At this time, the arc groove at the bottom of the pressure plate 92 is adapted to the lead trough 4, ensuring that the pressure plate 92 can fit tightly on the cable without causing damage to it. When the staff needs to stop laying the wire or move the laying device, they only need to fix the pressure plate 92 to ensure that the cable is firmly fixed in the lead trough 4 to prevent it from falling off or moving. This not only improves the safety of cable laying, but also reduces the risk of cable damage.

[0055] It should be noted that the present embodiment also includes two groups of rollers 7. One group of rollers 7 are arranged inside the mounting groove 6 for relative rotation. Grooves are relatively opened inside the guide groove 4. The other group of rollers 7 are arranged inside the corresponding grooves. The two groups of rollers 7 are located on both sides of the one-way conveying mechanism 5.

[0056] A group of rollers 7 are relatively rotatably arranged inside the installation groove 6. When the cable passes through the one-way conveying mechanism 5, this group of rollers 7 will contact the surface of the cable and rotate with the movement of the cable; another group of rollers 7 is arranged in the grooves relatively opened inside the lead groove 4, and these rollers 7 will also rotate with the movement of the cable, thereby effectively reducing the friction and resistance of the cable during the conveying process.

[0057] The two groups of rollers 7 are located on both sides of the one-way conveying mechanism 5. Such a layout ensures that the cable can be well supported and guided during the entire conveying process.
