Description

Technical Field

[0001] The utility model relates to the technical field of Messenger cable production equipment, in particular to a stranding device for Messenger cable production. Background Art

[0002] The catenary cable is a key component of the electrified railway contact network system. Its main function is to undertake the dual tasks of power transmission and suspension of contact network wires, ensuring that trains on the railway line can obtain electricity stably. The stranding device for the production of catenary cables is a device specially used for the production of catenary cables. This device can twist multiple metal wires into one, forming a stranded wire product with certain strength and structural stability.

[0003] A concentric high-speed stranding machine is disclosed in Chinese patent publication number CN219642602U. The concentric high-speed stranding machine passes wires through a wire reel into a stranding frame, and then starts a motor to strand multiple wires into a finished product.

[0004] However, the internal winding and reeling device of traditional twisting machines is usually unidirectional, and the wire can only be twisted in one direction during the twisting process, which can easily lead to uneven winding of the wire and uneven tightness during winding. Uneven wire winding will affect the appearance quality and performance of the product. After the wire is twisted during the twisting process, it needs to be reeled in by a reeling device, which can only reel in one direction. Therefore, the wire will be subjected to unidirectional pulling force during winding. This unidirectional pulling force will cause unstable tension of the wire, resulting in excessive or insufficient tension, thereby affecting the quality and safety performance of the product.

[0012] Beneficial effects:

[0013] The stranding device for the production of load-bearing cables is provided with a wire control component. When the wire between the sleeve near the turntable side and the turntable becomes loose due to transmission, the sleeve near the turntable side pushes the wire between the sleeve near the turntable side and the turntable, so that the section of wire quickly remains in a taut state. At the same time, the sleeve near the wire bundle side presses down the wire between the wire bundle and the sleeve near the turntable side, so that the inclination angle of the section of wire is reduced, thereby being able to quickly compensate for the stranding error caused by the loose wire, so that the section of wire can maintain tension while being tightly wound on the surface of the core wire, avoiding the situation where the tension is too large or too small and affects the quality and safety performance of the product.

A gear 44 is rotatably provided between two adjacent gear conditions 43 of the mounting plate 42, and sleeves 45 are fixedly provided at the ends of the plurality of gear conditions 43. A flexible pad 8 is fixedly provided on the sleeve 45 and the inner wall of the threading hole 31. The flexible pad 8 is made of polyethylene sponge. The polyethylene sponge can be used to clean dust and other impurities on the surface of the wire, thereby ensuring that the wire can be tightly wound together, and at the same time, it can have a wear-resistant effect, so that the flexible pad 8 has a long service life.

[0026] like Figures 4 to 6 As shown, the gear condition 43 is in a T-shape, and the positions of the mounting plate 42 corresponding to the gear conditions 43 are provided with sliding grooves 421 matched therewith, and the gear conditions 43 close to the rotating disk 3 are connected with the sliding grooves 421 through elastic members 422, and the positions of the mounting plate 42 corresponding to the gears 44 are provided with movable grooves 423, and the two ends of the mounting plate 42 corresponding to the gears 44 are provided with rotating holes, and the two ends of the gears 44 are connected with the rotating holes through bearings. By using the above-mentioned bearings, the friction force of the gear 44 during rotation can be reduced, and the stability of the gear 44 during rotation can be improved; when the sleeve close to the rotating disk 3 is When the wire between 45 and the turntable 3 becomes loose due to transmission, the sleeve 45 near the turntable 3 side pushes the wire between the sleeve 45 near the turntable 3 side and the turntable 3, so that the wire section quickly maintains a taut state, and at the same time, the sleeve 45 near the wire harness 5 side presses down the wire between the wire harness 5 and the sleeve 45 near the turntable 3 side, so that the inclination angle of the wire section is reduced, so that the twisting error caused by the loose wire can be quickly compensated, so that the wire section can maintain the tension and can be tightly wound on the surface of the core wire, avoiding the situation where the tension is too large or too small to affect the quality and safety performance of the product (such as Figures 2 to 4 as shown).

[0027] As a preferred technical solution of the utility model, Figure 1 to Figure 2As shown, the driving assembly 6 includes a first bracket 61 fixedly mounted on the top of the mounting plate 2, a transmission roller 62 is rotatably provided inside the first bracket 61, a motor 63 is fixedly mounted on the side of the first bracket 61, and the output end of the motor 63 passes through the first bracket 61 and is connected to the transmission roller 62, and the supporting assembly 7 includes a second bracket 71 fixedly mounted on the top of the mounting plate 2, a driven roller 72 is rotatably provided inside the second bracket 71, and by starting the motor 63, the transmission roller 62 controls the rotation of the turntable 3, and when the turntable 3 rotates, it drives the wire control assembly 4 to rotate synchronously, so that the wire is wound around the surface of the core wire.

[0028] The working process is as follows:

[0029] S1, such as Figure 1 , Figure 2 and Figure 6 As shown, when in use, the core wire is first passed through the connecting tube 41, and then the wires to avoid twisting are passed through the threading holes 31 and the two sleeves 45 in sequence, and then the motor 63 can be started to make the transmission roller 62 control the rotation of the turntable 3. When the turntable 3 rotates, it will drive the wire control assembly 4 to rotate synchronously, so that the wires are wound around the surface of the core wire;

[0030] S2, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, when the wire passes through the two sleeves 45, the elastic member 422 can make the gear condition 43 close to the rotating disk 3 have an upward thrust, so that the sleeve 45 close to the rotating disk 3 always keeps pushing the wire between the sleeve 45 close to the rotating disk 3 and the rotating disk 3;

[0031] S3, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, under the action of the gear 44, when the gear condition 43 near the side of the turntable 3 slides upward, the gear condition 43 near the side of the wire harness 5 slides downward, so that the sleeve 45 near the side of the wire harness 5 presses down the wire between the wire harness 5 and the sleeve 45 near the side of the turntable 3;

[0032] S4, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, when the wire between the sleeve 45 near the side of the turntable 3 and the turntable 3 is loosened due to transmission, the elastic member 422 is used to give an upward thrust to the gear member 43 near the side of the turntable 3, so that the sleeve 45 near the side of the turntable 3 pushes the wire between the sleeve 45 near the side of the turntable 3 and the turntable 3, so that the wire section is quickly kept in a taut state;

[0033] S5, such as Figures 1 to 4 As shown, when the toothed condition 43 near the side of the turntable 3 is upward, the toothed condition 43 near the side of the wire harness 5 will slide downward, so that the sleeve 45 near the side of the wire harness 5 will press down the wire between the wire harness 5 and the sleeve 45 near the side of the turntable 3, so that the inclination angle of the wire section is reduced (the inclination of the wire between the sleeve 45 near the side of the wire harness 5 and the wire harness 5 is reduced);

[0034] S6, such as Figures 1 to 4 As shown, when the inclination of the wire between the sleeve 45 on the side close to the wire harness 5 and the wire harness 5 is reduced, the twisting error caused by the relaxation of the wire can be quickly compensated, so that the section of wire can maintain the tension while being tightly wound on the surface of the core wire, avoiding the situation where the tension is too large or too small and affects the quality and safety performance of the product.
