Description

Technical Field

[0001] This utility model belongs to the field of steel wire rope production technology, and specifically relates to a steel wire rope twisting device. Background Technology

[0002] Steel wire ropes, with their high strength, high toughness, and good wear resistance, occupy an indispensable position in modern industrial systems. In the construction industry, tower cranes, hoists, and other lifting equipment rely on steel wire ropes to lift and transport building materials. Their safety is directly related to the lives of construction workers and the progress of the project. In the lifting industry, large equipment such as port cranes and bridge cranes need to use steel wire ropes to load, unload, and transport heavy objects, which places extremely high demands on the strength and stability of steel wire ropes. In mining operations, mine hoisting equipment uses steel wire ropes to transport ore and equipment. The harsh working environment poses severe challenges to the wear resistance and corrosion resistance of steel wire ropes.

[0003] However, traditional wire rope twisting devices have revealed many challenging problems in practical applications. During the twisting process, tension control of each wire strand is extremely critical. If the tension is uneven, the internal stress distribution of the twisted wire rope will be unbalanced. When the wire rope is under load, the stress concentration points are prone to wire deformation and breakage, leading to a loose overall structure and seriously threatening safety. For example, in situations with frequent lifting operations, safety accidents caused by poor wire rope twisting quality occur frequently, resulting in huge economic losses and personal injury.

[0004] Therefore, we propose a wire rope twisting device. Utility Model Content

It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0021] like Figure 1 As shown, a wire rope twisting device includes a fixed base 1, a mushroom-shaped drum 2 inside the fixed base 1, a support plate 3 on one side of the fixed base 1, a straightening machine 4 on the upper side of the support plate 3, a winding drum 5 on the other side of the support plate 3, six support legs 6 on the lower side of the fixed base 1 and the support plate 3, the upper ends of the six support legs 6 being fixedly connected to the lower surfaces of the fixed base 1 and the support plate 3 respectively, a protective cover 101 on the upper side of the fixed base 1, one side of the protective cover 101 being movably connected to one side of the fixed base 1 via a hinge, and a fixed plate 102 inside the fixed base 1.

[0022] like Figure 1 As shown, the fixed base 1 is used to install and fix the twisting device. The mushroom-shaped drum 2 rotates to twist different numbers of steel wires into a single wire. The support plate 3 is used to install and fix the straightening machine 4. After the steel wires are twisted into a single wire, they are straightened to unify the stress of the steel wires and improve the service life of the steel wire rope. The support leg 6 supports the fixed base 1 and the support plate 3. The winding drum 5 winds up and collects the twisted steel wire rope. The protective cover 101 works with the fixed base 1 to cover the steel wire twisting device and prevent the steel wire from breaking and injuring the user during twisting.

[0023] like Figures 1-4As shown, the fixing plate 102 has eighteen straight slot-shaped through holes, and the center of the fixing plate 102 has a circular through hole. A rope channel tube 103 is provided on one side of the fixing plate 102. One end of the rope channel tube 103 is fixedly connected to the center of one side of the fixing plate 102. The rope channel tube 103 communicates with the circular through hole in the center of the fixing plate 102. A drive motor 104 is provided on one side of the fixing plate 102, and a drive gear 105 is provided on the output shaft of the drive motor 104.

[0024] like Figures 1-4 As shown, the mushroom rotating cylinder 2 has a mushroom-shaped hollow structure. The hemp rope channel tube 103 passes through the hollow part of the mushroom rotating cylinder 2. The mushroom rotating cylinder 2 is rotatably engaged with the hemp rope channel tube 103. The outer ring of the small end of the mushroom rotating cylinder 2 is provided with a ring gear 201. The ring gear 201 meshes with the drive gear 105. The circumference of the mushroom rotating cylinder 2 is provided with eighteen wire grooves 202 at equal intervals.

[0025] like Figures 1-4 As shown, steel wires of different numbers are passed circumferentially through the straight groove-shaped through holes on the fixing plate 102 at equal intervals, and then through the wire groove 202. The hemp rope is passed through the hemp rope channel tube 103, and one end of the hemp rope is connected and fixed to one end of the multiple strands of steel wire. The rope passes between the two straightening wheels 401 on the straightening machine 4. The tension between the two straightening wheels 401 on the straightening machine 4 drives the hemp rope and steel wire to move onto the winding drum 5. At the same time, the drive motor 104 is started. The drive motor 104 drives the ring gear 201 to rotate through the drive gear 105. The ring gear 201 drives the mushroom drum 2 to rotate, so that the multiple strands of steel wire are twisted around the hemp rope.

[0026] like Figures 1-2 As shown, the straightening machine 4 has two straightening wheels 401 on one side, and the support plate 3 is also provided with a guide seat 301, and the guide seat 301 is provided with six auxiliary straightening wheels 302.

[0027] like Figures 1-2 As shown, the two straightening rollers 401, under the action of the straightening machine 4, work with the mushroom-shaped drum 2 to twist the wire rope. After twisting, the straightening machine 4 drives the straightening rollers 401 to straighten it immediately, making it more stable and improving the service life of the wire rope.

[0028] like Figures 1-2 As shown, the take-up drum 5 has two limiting plates 501 on each side. The take-up drum 5 is a hollow cylindrical structure. The center of each of the two limiting plates 501 has two circular through holes. The hollow structure of the take-up drum 5 contains a take-up shaft 502. The take-up drum 5 has a take-up bracket 503 at the bottom. The inner two sides of the take-up bracket 503 are fixedly connected to the two ends of the two take-up shafts 502 respectively.

[0029] The working principle of this utility model is as follows: In actual use, steel wires of different numbers are passed circumferentially through the straight groove-shaped through holes on the fixing plate 102, and then through the wire groove 202. The hemp rope is passed through the hemp rope channel tube 103, and one end of the hemp rope is connected and fixed to one end of the multiple strands of steel wire. The rope passes between the two straightening wheels 401 on the straightening machine 4. The tension between the two straightening wheels 401 on the straightening machine 4 drives the hemp rope and steel wire to move onto the winding drum 5. At the same time, the drive motor 104 is started. The drive motor 104 drives the ring gear 201 to rotate through the drive gear 105. The ring gear 201 drives the mushroom drum 2 to rotate, so that the multiple strands of steel wire are twisted around the hemp rope. After being straightened by the straightening wheel 401 driven by the straightening machine 4, the rope is then wound and stored by the rotation of the winding drum 5 after passing through the auxiliary straightening wheel 302.

[0030] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
