Description

Technical Field

[0001] The utility model relates to the field of cable processing equipment, and more specifically, to a cable stranding machine. Background Art

[0002] Power cables are used to transmit and distribute electrical energy. They are commonly used in urban underground power grids, outgoing lines from power stations, internal power supply in industrial and mining enterprises, and underwater transmission lines across rivers and seas. A stranding machine is one of the equipment for producing cables. The stranding machine is an important equipment in cable production. It is used to twist multiple wires or thin lines into the core wire of a cable, which helps to improve the flexibility, durability, and electrical conductivity of the cable. It can also reduce signal loss and increase the durability and flexibility of the cable.

[0003] Patent No. CN 219202855U discloses a stranding machine for cable processing with controllable tension, which relates to the related technical field of cable processing equipment. It includes a base, a rotating disk, a stranding driving mechanism, and a tension adjusting mechanism. The rotating disk, the wire driving mechanism, and the tension adjusting mechanism are all arranged above the base. The tension adjusting mechanism is located on one side of the stranding driving mechanism, and the rotating disk is located on the other side of the stranding driving mechanism. The tension adjusting mechanism includes an upper auxiliary roller, a lower auxiliary wheel, a tension adjusting roller, a sliding rod, and a bracket. Through the stranding driving mechanism, multiple single-conductor wires can be gradually twisted together. When the tension adjusting roller moves upward, it can gradually press against the wire body passing above the tension adjusting roller, thereby increasing the tension. When the tension adjusting roller moves downward, the wire body it presses against is gradually relaxed, reducing the tension.

[0004] In the above patent, the inventor believes that although the patent satisfies the adjustment of the tension during stranding wire transportation, during the process of replacing the wire pay-off reel, the stranding machine needs to be shut down, and it can only be started after the replacement of the wire pay-off reel is completed. The entire stranding machine needs to be shut down for a long time, and this shutdown process affects the efficiency of cable stranding. Summary of the Utility Model

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a cable stranding machine. The technical problem to be solved by the utility model is: during the process of replacing the wire pay-off reel of the current cable stranding machine, the stranding machine needs to be shut down, and it can only be started after the replacement of the wire pay-off reel is completed.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following specific embodiments illustrate the embodiments of the present utility model. Those skilled in this technology can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0023] With reference toFigures 1 - 4 The utility model provides a cable stranding machine, including a stranding structure and a sliding support structure. The sliding support structure includes a pair of fixed seats 1, a pair of polished rods 2 fixedly connected to the pair of fixed seats 1, and a sliding frame 3 slidably connected to the pair of polished rods 2. One of the fixed seats 1 is provided with a hydraulic device 4 for controlling the linear movement of the sliding frame 3. The sliding frame 3 is respectively connected to a pair of pay-off drums 5 through a first rotating shaft. The hydraulic device 4 can drive the sliding frame 3 to move horizontally on the polished rod 2, so that the pair of pay-off drums 5 can flexibly adjust their positions to correspond to the stranding structure. 3 is provided with a motor 6 for driving the pay-off drum 5 to rotate, and the motor 6 drives the pay-off drum 5 to rotate, so that the pay-off drum 5 can cooperate with the stranding processing of the stranded cable structure. A plurality of assembly structures 7 are provided on each pay-off drum 5, and the assembly structure 7 is detachably connected with the pay-off roller 8. Because a pair of pay-off drums 5 can flexibly correspond to the axial position of the stranded structure, when a pay-off drum 5 is used for pay-off, the other pay-off drum 5 in an idle state can replace the pay-off roller 8, thereby reducing the length of the stranding downtime by replacing a pair of pay-off drums 5.

[0024] The stranded wire structure includes a bracket 9, a stranded wire drum 91 rotatably connected to the bracket 9 through a second rotating shaft, and a wire paralleling tube 92 fixedly connected to the bracket 9. The stranded wire drum 91 is used for the wire core on the pay-off roller 8 to pass through, so that the stranded wire drum 91 can drive several wire cores for winding, and the wire paralleling tube 92 is used for centralized transmission. The bracket 9 is located directly in front of the light rod 2. One end of the second rotating shaft of the stranded wire drum 91 is fixedly connected to a passive clamping rod 11, and each pay-off drum 5 is fixedly connected to an active plug-in rod 10 for transmission connection of the passive clamping rod 11.

[0025] The motor 6 is connected to the first rotating shaft of the pay-off drum 5 through a pulley drive mechanism. The motor 6 is used to drive the wire core on the pay-off roller 8 on the pay-off drum 5 to rotate around the axis. At the same time, the twisting drum 91 also passes through synchronously, so that the multiple wire cores concentrated through the paralleling tube 92 can be twisted together.

[0026] The assembly structure 7 includes a bracket 71 fixedly connected to the end face of the wire reel 5, a pair of limiting rolling grooves 72 opened on the bracket 71 and a pair of limiting bolts 73 threaded through the bracket 71, and the limiting bolts 73 pass through the limiting rolling grooves 72. In this application, the limiting rolling grooves 72 are composed of a multi-section groove structure, namely a first transverse groove, an oblique groove and a second transverse groove, and the oblique grooves are chamfered at the connection with the first transverse groove and the second transverse groove respectively.

[0027] Both ends of the wire pay-off roller 8 are fixedly connected with shaft rods. Support bearings 12 are arranged on the shaft rods. The support bearings 12 are slidably inserted into the limit rolling grooves 72, and the limit bolts 73 are in movable abutment with the outer rings of the support bearings 12. When the wire pay-off roller 8 is replaced, the support bearings 12 can be used in conjunction with the wire pay-off roller 8. By sliding the support bearings 12 into the second transverse groove at the deepest part of the limit rolling grooves 72, a certain degree of limiting effect can be achieved. Subsequently, by screwing the limit bolts 73 into the limit rolling grooves 72, the positions of the support bearings 12 can be limited. In this way, the wire pay-off roller 8 can rotate through the support bearings 12 and rotate for wire pay-off in the limit rolling grooves 72.

[0028] It should be noted that when the wire pay-off roller 8 on the assembly structure 7 needs to be replaced, the wire pay-off disk 5 is controlled to rotate, and the wire pay-off roller 8 is taken out from the assembly structure 7 at the lowest position of the wire pay-off disk 5. Due to the multi-section groove structure of the limit rolling grooves 72, the wire pay-off roller 8 can be easily pulled out through the support bearings 12, meeting the convenience of replacing the wire pay-off roller 8.

[0029] Wire holes are arranged on the wire twisting disk 91, and the wire holes are used for threading the wire cores on the wire pay-off roller 8.

[0030] One end of the active insertion rod 10 is provided with a convex block, and one end of the passive clamping rod 11 facing the active insertion rod 10 is provided with a groove, and the convex block is movably inserted into the groove.

[0031] Specifically, when replacing the position of the wire pay-off disk 5 for wire twisting of the electric wire, one of the wire pay-off disks 5 is moved to a position coaxially corresponding to the wire twisting disk 91 through the hydraulic device 4. At this time, the active insertion rod 10 can be close to the position of the passive clamping rod 11. Since the passive clamping rod 11 can rotate through the second rotating shaft of the wire twisting disk 91 to ensure that the position of the groove corresponds horizontally to the convex block, when the wire pay-off disk 5 is moved to a position coaxially with the wire twisting disk 91, the convex block can enter the groove. In this way, when the wire pay-off disk 5 rotates, it can synchronously drive the wire twisting disk 91 to rotate for wire twisting.
