Description

Technical Field

[0001] This utility model relates to the field of wire rope processing, and in particular to a tube stranding machine for wire rope stranding. Background Technology

[0002] The tube stranding machine mainly uses a motor to drive the winding roller to rotate, so that multiple steel wires are twisted together during the rotation to form a steel wire rope. During the twisting process, the steel wires are released from the pay-off frame, pass through the guide device and the wire-splitting die, and enter the rotating drum. The twisting is completed in the drum. Finally, the traction device pulls the twisted steel wire rope to the take-up reel for take-up.

[0003] A search revealed Chinese Patent Publication No. CN219218534U, which discloses an adjustable wire rope tube winch. This utility model includes a base plate, a horizontal plate fixedly connected to one side of a slider and fitting against the inner sides of two vertical plates, a guide roller mounted on the top of the horizontal plate, a rod movably connected to a groove on one side of the horizontal plate, one side of the outer wall of the rod movably connected to a groove on one side of the other vertical plate, one side of the rod being fixedly connected to a groove on one side of the horizontal plate via a spring, and the lower part of the outer wall of the rod being movably connected to a through hole at the bottom of the horizontal plate. This utility model relates to the field of tube winch technology. Through the cooperation between the plate, spring, and guide roller, it achieves rapid adjustment of the guide roller position, solving the problem that the distance between the two guide rollers in existing tube winches is fixed, requiring the user to use bolts to disassemble and replace or adjust the distance between the guide rollers when adjustment is needed, which is cumbersome and reduces work efficiency.

[0004] The above-mentioned technologies rely solely on the elastic force of springs for adjustment and lack a rigid limiting structure. When the wire rope generates lateral tension or the equipment vibrates during traction, the guide roller is prone to displacement, causing the wire rope guide trajectory to deviate, resulting in problems such as skewed winding and uneven winding. Therefore, a tube stranding machine for wire rope stranding is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a tube stranding machine for wire rope stranding, which aims to improve the problem in the prior art that "the guide roller adjustment method of the tube stranding machine is unstable and lacks a rigid limiting structure, resulting in inaccurate wire rope guidance and poor winding quality".

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a wire rope stranding machine, comprising a machine body, a base plate provided on the front side of the machine body, a support seat provided on the upper part of the base plate, and a guide assembly provided on the upper part of the support seat; the guide assembly includes a fixing member fixedly connected to the upper part of the support seat, multiple sets of mounting seats provided on the outer side of the fixing member, guide rollers provided on the inner side of two adjacent sets of mounting seats via a disassembly assembly, a connecting plate fixedly connected to the opposite side of the lower two sets of mounting seats, a servo motor fixedly connected to the lower outer side of the support seat, a bidirectional lead screw fixedly connected to the output shaft of the servo motor, a threaded sleeve provided on the outer side of the bidirectional lead screw, a slider fixedly connected to the outer side of the threaded sleeve, and the slider and the connecting plate hinged by a hinge rod.

[0011] As a further description of the above technical solution:

[0012] The slider and hinge rod are provided in two sets, and are symmetrically arranged with respect to the center line of the bidirectional lead screw.

[0013] As a further description of the above technical solution:

[0014] The smooth surface of the bidirectional lead screw is rotatably connected to the inner wall of the support base.

[0015] As a further description of the above technical solution:

[0016] The support base is provided with auxiliary components on both the front and rear sides. The auxiliary components include a fixed base that slides on the outside of the support base. An auxiliary roller is rotatably connected to the upper part of the fixed base. A bolt is threadedly connected to the lower part of the fixed base.

[0023] 2. In this utility model, the auxiliary components on the front and rear sides of the support base slide within the groove through the fixed base, which can adjust the position of the auxiliary roller.

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1-3 This utility model provides an embodiment of a wire rope stranding machine, comprising a body 1, which is the main structure of the wire rope stranding machine, providing support and installation foundation for the entire equipment. The body 1 integrates core components such as a motor and winding rollers to realize the stranding operation of the wire rope. A base plate 2 is provided on the front side of the body 1, mainly serving to stabilize and support the support seat 3. The support seat 3 is provided on the upper part of the base plate 2, used to connect and support the guide assembly 4 and auxiliary assembly 5. The guide assembly 4 is provided on the upper part of the support seat 3, including a fixing member 41 fixedly connected to the upper part of the support seat 3. The upper part of the fixing member 41 is plate-shaped and the lower part is cylindrical. Multiple sets of mounting seats 42 are provided on the outer side of the fixing member 41 for mounting guide rollers 48, providing installation positions and support for the guide rollers 48. The upper two sets of mounting seats 42 are installed on the lower plate-shaped side of the fixing member 41, and the lower two sets of mounting seats 42 slide on the lower cylindrical outer side of the fixing member 41.

[0034] Reference Figures 3-5 Guide rollers 48 are installed on the inner sides of the two adjacent sets of mounting seats 42 via the disassembly assembly 6 to guide the wire rope. Connecting plates 47 are fixedly connected to opposite sides of the two lower sets of mounting seats 42 to connect them and allow for vertical adjustment. A servo motor 43 is fixedly connected to the outer side of the lower part of the support base 3 as a power source, featuring a self-locking function. Its output shaft is fixedly connected to a bidirectional lead screw 44. By precisely controlling the rotation of the servo motor 43, the bidirectional lead screw 44 is rotated, providing stable power for the displacement adjustment of the guide rollers 48. The output shaft of 43 is fixedly connected to a bidirectional lead screw 44. The smooth surface of the bidirectional lead screw 44 is rotatably connected to the inner wall of the support base 3. When the bidirectional lead screw 44 rotates, the threaded sleeve drives the slider 45 to move along the axial direction of the bidirectional lead screw 44, achieving precise linear displacement and providing stable displacement drive for the adjustment of the guide roller 48. A threaded sleeve is provided on the outside of the bidirectional lead screw 44, and a slider 45 is fixedly connected to the outside of the threaded sleeve. The slider 45 is hinged to the connecting plate 47 through a hinge rod 46. The hinge rod 46 is inclined, and the connecting plate 47 moves up and down by changing the angle of the hinge rod 46.

[0035] Reference Figure 4 and Figure 5The disassembly assembly 6 includes a mounting component 61, which is inserted into the inner wall of the mounting base 42 and fixed to the outer side of the mounting base 42 by screws 62. This facilitates the installation and disassembly of the guide roller 48. When the guide roller 48 is worn or needs to be replaced, simply unscrew the screws 62 and remove the mounting component 61 to quickly replace the guide roller 48, improving equipment maintenance efficiency. The outer side of the guide roller 48 is equipped with a bearing, which can reduce the friction when the guide roller 48 rotates, making the guide roller 48 rotate more smoothly when guiding the wire rope. Two sets of sliders 45 and hinge rods 46 are provided and are symmetrically arranged around the center line of the bidirectional lead screw 44.

[0036] Reference Figure 3 and Figure 6 Auxiliary components 5 are provided on both the front and rear sides of the support base 3. The auxiliary components 5 include a fixed seat 51 that slides on the outside of the support base 3. The lower part of the support base 3 is provided with a groove. The fixed seat 51 slides on the inner wall of the groove. By sliding in the groove, the position of the auxiliary roller 52 can be adjusted to adapt to the guiding requirements of wire ropes of different specifications. The upper part of the fixed seat 51 is rotatably connected to the auxiliary roller 52, which works in conjunction with the guide roller 48. The auxiliary roller 52 guides and supports the wire rope from different angles, further optimizing the guiding effect of the wire rope and ensuring that the wire rope maintains a stable position and direction. The lower part of the fixed seat 51 is threaded with a bolt 53. The upper part of the bolt 53 is fixedly connected with a pressing member 54. The pressing member 54 contacts the outside of the support base 3. When the bolt 53 is rotated, the pressing member 54 will contact and press the outside of the support base 3, fixing the fixed seat 51 on the support base 3 and preventing the fixed seat 51 from shifting during operation, thus ensuring the stability of the auxiliary roller 52.

[0037] Working principle: When in use, according to the specifications of the wire rope to be stranded, the operator first adjusts the auxiliary component 5, tightens the bolt 53 at the bottom of the fixed seat 51, so that the pressing part 54 releases the pressure on the support seat 3, slides the fixed seat 51 in the groove at the bottom of the support seat 3 to a suitable position, and then tightens the bolt 53 in the opposite direction, so that the pressing part 54 presses the support seat 3, fixes the position of the auxiliary roller 52, and ensures that the auxiliary roller 52 can work with the guide roller 48 to guide the wire rope.

[0038] Start the servo motor 43 on the outer side of the lower part of the support base 3. The output shaft of the servo motor 43 drives the bidirectional lead screw 44 to rotate. The threaded sleeve on the outer side of the bidirectional lead screw 44 rotates and moves along the lead screw axis. Since the slider 45 is fixedly connected to the outer side of the threaded sleeve, the slider 45 will make linear motion on the bidirectional lead screw 44.

[0039] When the slider 45 moves, the inclined structure of the hinge rod 46 will convert the linear motion of the slider 45 into a pushing and pulling force on the connecting plate 47, so that the connecting plate 47 drives the mounting base 42 and the guide roller 48 to move up and down, so as to achieve precise adjustment of the position of the guide roller 48 to adapt to the guiding requirements of the wire rope under different working conditions.

[0040] After adjusting the positions of the guide roller 48 and the auxiliary roller 52, the wire rope passes through the auxiliary roller 52 and the guide roller 48 in sequence. The bearing on the outer side of the guide roller 48 reduces the friction between the wire rope and the guide roller 48, allowing the wire rope to slide smoothly on the guide roller 48. The guide roller 48 guides the wire rope.

[0041] If the guide roller 48 wears out during long-term operation of the pipe stranding machine, it needs to be replaced. At this time, the operator only needs to unscrew the screw 62 on the mounting part 61, remove the mounting part 61 from the inner wall of the mounting base 42, and then remove the worn guide roller 48. Then, replace it with a new guide roller 48, insert the mounting part 61 into the mounting base 42 and fix it with the screw 62 to complete the replacement of the guide roller 48 and ensure the continuous and stable operation of the equipment.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
