Abstract

The utility model relates to a frame strander traction device, which comprises an adjusting mechanism, a driving mechanism, a fastening mechanism and a compensation mechanism, and is characterized in that the driving mechanism is arranged above the middle part of the adjusting mechanism, the driving mechanism comprises a positioning frame and a driving wheel, and the driving wheel is rotatably connected to the inner side wall of the positioning frame; the fastening mechanism comprises a protective shell and a plurality of auxiliary wheels. According to the frame-type strander traction device, through cooperative arrangement of the driving wheel, the protective shell and the auxiliary wheel, a relatively narrow space can be formed between the driving wheel and the auxiliary wheel, so that when a cable passes through, the cable can be dragged by means of relative extrusion between the driving wheel and the auxiliary wheel and inertial rotation of the driving wheel, and in the traction process, the cable can be conveniently pulled out. If the cable is subjected to large resistance, relative sliding is formed between the cable and the driving wheel by means of independent rotation of the auxiliary wheel, and therefore the situation that the cable is damaged due to too large traction force is reduced.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] This utility model embodiment provides a traction device, which is applied to the scenario of pulling the cable produced by the frame stranding machine during the cable production process. In this embodiment, the structure of the traction device is improved to give it the advantages of stable traction and adaptive tension adjustment. Specifically, taking the production of frame stranded cable as an example, as a preferred solution in this embodiment, the traction device is specifically a frame stranding machine traction device, which can stably pull the produced cable.

[0029] Example: This example provides a traction device for a cable stranding machine, which is applied to the scenario of pulling and traction of cables produced by a cable stranding machine during the cable production process. Figure 1 and 2 As shown, the frame winch traction device of this embodiment includes an adjusting mechanism 1, a driving mechanism 3, a fastening mechanism 4, and a compensation mechanism 6. As... Figure 4As shown, the drive mechanism 3 is located above the middle of the adjustment mechanism 1. The drive mechanism 3 includes a positioning frame 301 and a drive wheel 304, which is rotatably connected to the inner wall of the positioning frame 301. The fastening mechanism 4 includes a protective shell 401 and multiple auxiliary wheels 402. The end of the protective shell 401 is detachably connected to the outer wall of the positioning frame 301, and the inner wall of the protective shell 401 is sleeved with the outer surface of the drive wheel 304. The multiple auxiliary wheels 402 are rotatably connected to the inner wall of the protective shell 401. Figure 6 As shown, the compensation mechanism 6 includes a guide cylinder 602, a compression spring 603, a guide rod 604, and a first guide wheel 605. The guide cylinder 602 is disposed on the top of the adjustment mechanism 1 and located on one side of the positioning frame 301. One end of the compression spring 603 is fixedly connected to the inner bottom wall of the guide cylinder 602, and the other end of the compression spring 603 is fixedly connected to the end of the guide rod 604. The other end of the guide rod 604 is rotatably connected to the outer wall of the first guide wheel 605 through a rotating shaft.

[0030] In this embodiment, the positioning frame 301 provides an installation carrier for components such as the drive wheel 304, ensuring the accurate and stable installation position of the drive wheel 304. Simultaneously, it connects with other mechanisms such as the fastening mechanism 4 and the power mechanism 5, working collaboratively to achieve the traction of the cable 8, ensuring the stable operation of the entire drive system. The drive wheel 304 is rotatably connected to the inner wall of the positioning frame 301, providing traction power to the cable 8 through its own rotation. Cooperating with the auxiliary wheel 402, it tractions the cable 8 under relative compression and inertial rotation. It is one of the core components for realizing the traction of the cable 8, and its rotational speed and operational stability directly affect the cable... 8. Traction Effect: The protective shell 401 is detachably connected to the outer wall of the positioning frame 301 at its end, and its inner wall is sleeved with the outer surface of the drive wheel 304, providing protection for the drive wheel 304 and the cable 8, preventing foreign objects from entering and affecting the normal operation of the drive wheel 304. Simultaneously, it cooperates with the auxiliary wheel 402 to provide a stable traction environment for the cable 8, ensuring a safe and reliable traction process. Multiple auxiliary wheels 402 are rotatably connected to the inner wall of the protective shell 401, cooperating with the drive wheel 304 to form a narrow space between them. Traction of the cable 8 is achieved through relative compression and the inertial rotation of the drive wheel 304. When the cable 8 is subjected to significant... When resistance is encountered, the auxiliary wheel 402 can rotate independently, allowing relative sliding between the cable 8 and the drive wheel 304. This reduces the risk of damage to the cable 8 due to excessive traction, effectively protecting the cable 8 and improving the traction effect. The guide cylinder 602 provides a guiding path for the sliding of the guide rod 604, ensuring that the guide rod 604 can slide smoothly in a predetermined direction when subjected to tension. In conjunction with the compression spring 603, it achieves adaptive adjustment of the traction force on the cable 8. When the cable 8 is subjected to a large tension, the compression spring 603 is compressed, reducing the tensile force on the cable 8; when the cable 8 becomes loose, the compression spring 603 springs back. The force pulls the cable 8 taut, ensuring normal traction of the cable 8, effectively protecting the cable 8 and improving traction quality. The guide rod 604 transmits the tension to the compression spring 603, while simultaneously driving the first guide wheel 605 to move, realizing real-time response and adjustment of the tension of the cable 8, ensuring that the force on the cable 8 is always within a suitable range during traction. The first guide wheel 605 changes the direction of movement of the cable 8, enabling the cable 8 to better adapt to the device structure during traction. At the same time, in conjunction with the compression spring 603 and the guide rod 604, it adaptively adjusts the tension on the cable 8, ensuring the stability and smoothness of cable traction.

[0031] In the above embodiments, such as Figure 3As shown, the adjustment mechanism 1 includes a support plate 101, two limiting plates 102, two guide grooves 103, a sliding rod 104, a threaded rod 105, and a first motor 106.

The first motor 106 is fixedly installed on the outer wall of one of the limiting plates 102. The output end of the first motor 106 is connected to the end of the threaded rod 105 via a key. The support plate 101 provides an installation support platform for the entire adjustment mechanism 1 and other related mechanisms, ensuring the stability of the relative positional relationship between the mechanisms and ensuring the stability of the traction device. The overall structure is stable. The limiting plate 102 restricts the displacement of other parts in a specific direction, ensuring that the sliding rod 104 and the threaded rod 105 are accurately installed and will not deviate during operation, thus ensuring the normal operation of the adjustment mechanism 1.

The sliding rod 104 provides stable support and sliding guidance for the support plate 201, preventing the support plate 201 from shaking or deviating during adjustment, and improving the stability of adjustment. The threaded rod 105 rotates under the drive of the first motor 106, converting the rotational motion into the linear motion of the support plate 201, achieving precise adjustment of the position of the support plate 201, and thus adjusting the position of the drive mechanism 3, etc., to meet different cable traction requirements.

[0032] In the above embodiment, the top of the adjusting mechanism 1 is provided with a support mechanism 2. The support mechanism 2 includes a support plate 201, a guide sleeve 202, and a threaded sleeve 203. The bottom of the support plate 201 is slidably connected to the top of the support plate 101. The tops of the guide sleeve 202 and the threaded sleeve 203 are respectively fixedly connected to the bottom of the support plate 201.

The outer surface of the threaded sleeve 203 is slidably connected to the inner wall of the other guide groove 103 and is threadedly connected to the outer wall of the threaded rod 105. The middle part of the top of the support plate 201 is fixedly connected to the bottom of the positioning frame 301. The support plate 201 supports the positioning frame 301. The 01 and related mechanisms transmit the adjustment action of the adjustment mechanism 1 to the drive mechanism 3 and other parts, ensuring that each mechanism works in coordination. At the same time, it provides an installation base for other parts such as the fixing frame 601, ensuring that the entire traction device is compact and stable. The guide sleeve 202 provides guidance and stable support for the sliding of the support plate 201, so that the support plate 201 remains stable during the adjustment process, avoiding shaking and deviation, and ensuring the stability of the traction device. The threaded sleeve 203 converts the rotational motion of the threaded rod 105 into the linear motion of the support plate 201, and works in coordination with the guide sleeve 202 to precisely control the position of the support plate 201, thereby achieving precise adjustment of the drive mechanism 3 and other parts, meeting the position requirements of the traction device for different cable production processes.

[0033] In the above embodiments, see Figure 4 and Figure 5 The drive mechanism 3 also includes a first mounting groove 302, a second mounting groove 303, multiple counterweights 305, and washers 306. The first mounting groove 302 is located above the outer surface of the positioning frame 301, and its inner wall is rotatably connected to the outer surface of the drive wheel 304. The second mounting groove 303 is located below the outer surface of the positioning frame 301. The multiple counterweights 305 are fixedly mounted on the outer wall of the drive wheel 304, and the washers 306 are fitted onto the outer surface of the drive wheel 304. The drive mechanism 3 is connected via the first mounting groove 302. 2 provides precise positioning and support for the installation of the drive wheel 304, ensuring that the drive wheel 304 is firmly installed and rotates flexibly, and ensuring that the drive wheel 304 can stably provide traction power for the cable 8. The second mounting groove 303 can provide space for the cable 8 to move in a traction manner. The counterweight 305 can adjust the center of gravity distribution of the drive wheel 304, increase the rotational inertia of the drive wheel 304, make the drive wheel 304 run more smoothly when tractioning the cable 8, reduce the speed fluctuation caused by load changes, and improve the stability of cable 8 traction.

[0034] In the above embodiments, see Figure 2 and Figure 4A power mechanism 5 is provided on the outer surface of the positioning frame 301. The power mechanism 5 includes a second motor 501, a driving wheel 502, a driven wheel 503, and a belt 504. The second motor 501 is fixedly installed on the outer wall of the positioning frame 301 and located below the protective shell 401. The outer surface of the driving wheel 502 is connected to the output end of the second motor 501 by a key. The outer wall of the driven wheel 503 is connected to the middle of the outer surface of the drive wheel 304 by a drive shaft by a key. The two sides of the inner sidewall of the belt 504 are respectively sleeved on the outer walls of the driving wheel 502 and the driven wheel 503. The second motor 501 provides rotational power to the driving wheel 502. Its output end is connected to the driving wheel 502 by a key, which can precisely control the speed and direction of the driving wheel 502. In turn, the belt 504 and the driven wheel 503 drive the drive wheel 304 to rotate, providing a stable power source for the traction of the cable 8. The driving wheel 502 drives the second motor 501. The power is transmitted to the belt 504, which drives the driven wheel 503 and the drive wheel 304 to rotate. The speed and running stability of the driven wheel 304 directly affect the speed of the drive wheel 304 and the traction speed of the cable 8. The driven wheel 503: its outer wall is connected to the middle of the outer surface of the drive wheel 304 through the transmission shaft, and is connected to the drive wheel 502 through the belt 504. It transmits the power of the drive wheel 502 to the drive wheel 304, which drives the drive wheel 304 to rotate, thereby traction of the cable 8. Its cooperation with the drive wheel 502 ensures smooth power transmission and stable operation of the drive wheel 304. The inner side wall of the belt 504 is respectively sleeved on the outer wall of the drive wheel 502 and the driven wheel 503, transmitting power between the drive wheel 502 and the driven wheel 503. The elastic deformation of the belt 504 can buffer the impact during the power transmission process, ensuring smooth power transmission, making the drive wheel 304 run more smoothly, and improving the stability of cable traction.

[0035] In the above embodiments, such as Figure 6 As shown, the compensation mechanism 6 also includes a fixed frame 601 and a second guide wheel 606. The bottom of the fixed frame 601 is fixedly installed on the top of the support plate 201 and located on one side of the positioning frame 301. The top of the fixed frame 601 is bolted to the outer wall of the guide cylinder 602. The second guide wheel 606 is rotatably connected to the inner wall of the fixed frame 601 and located below the guide cylinder 602. The fixed frame 601 provides installation support for the guide cylinder 602 and the second guide wheel 606, ensuring that the installation position of the guide cylinder 602 and the second guide wheel 606 is accurate and stable, so that they can function normally and work with other parts to adjust the tension during the traction process of the cable 8. The second guide wheel 606 further changes the movement path of the cable 8 and works in conjunction with the first guide wheel 605 to keep the cable 8 in good operating condition during the traction process, reduce the friction and interference between the cable 8 and other parts of the device, and improve the traction effect of the cable 8.

[0036] In the above embodiments, see Figure 1 ,2 and Figure 4 A pulling mechanism 7 is provided on the top of the support plate 201 on the other side of the positioning frame 301. The pulling mechanism 7 includes a fixed base 701, five limit wheels 702, and two third motors 703. The bottom of the fixed base 701 is fixedly connected to the top of the support plate 201 on the other side of the positioning frame 301. All five limit wheels 702 are rotatably connected to the inner wall of the fixed base 701. The two third motors 703 are fixedly installed on the outer surface of the fixed base 701. The output ends of the two third motors 703 are respectively connected to the ends of the two limit wheels 702 via keys. The mounting base 701 provides installation support for the limiting wheel 702 and the third motor 703, ensuring that the limiting wheel 702 and the third motor 703 are installed accurately and stably, enabling them to work normally and cooperate with other mechanisms to achieve traction of the cable 8. The limiting wheel 702 plays a limiting and guiding role for the cable 8, ensuring that the cable 8 maintains the correct movement trajectory during traction and preventing the cable 8 from deviating or getting tangled. At the same time, under the drive of the third motor 703, part of the limiting wheel 702 rotates, providing additional pulling power for the cable 8 and improving the traction effect of the cable 8.

[0037] In the above embodiment, the outer surface of the drive wheel 304 is wound with a cable 8. The cable 8 passes through the outer wall of the protective shell 401 and is connected to the outer wall of the first guide wheel 605 and the second guide wheel 606. One end of the cable 8 passes through the positioning frame 301 and is connected to the outer surface of the five limit wheels 702.

[0038] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0039] When using the frame stranding machine traction device of this utility model embodiment for cable production, the working steps and principle are as follows:

[0040] First, one end of the cable 8 is wrapped around the outer surface of the drive wheel 304, so that the cable 8 passes through the inner wall of the protective shell 401 and is connected to the outer wall of the first guide wheel 605 and the second guide wheel 606. Finally, one end of the cable 8 passes through the positioning frame 301 and passes between the five limit wheels 702, so that the limit wheels 702 can drive the cable 8 to move.

[0041] Next, the second motor 501 is started, which drives the drive wheel 304 to rotate through the drive wheel 502, driven wheel 503 and belt 504. The drive wheel 304 cooperates with the auxiliary wheel 402 to achieve traction of the cable 8 by means of relative compression and inertial rotation. During the traction process, if the cable 8 is subjected to great resistance, the auxiliary wheel 402 will rotate independently, so that the cable 8 and the drive wheel 304 form relative sliding, reducing the possibility of the cable 8 being damaged due to excessive traction force.

[0042] Then, when the cable 8 is subjected to a large tension, the guide rod 604 slides inside the guide cylinder 602, squeezing the compression spring 603. The elastic deformation distance of the compression spring 603 is used to make timely adaptive adjustments to the tension force during the traction process, reducing the tensile force on the cable 8. When the cable 8 becomes loose, the elastic force of the compression spring 603 will tighten the cable 8, ensuring normal traction of the cable 8.

[0043] Finally, starting the first motor 106 can drive the threaded rod 105 to rotate forward or backward, thereby adjusting the position of the support mechanism 2 and thus adjusting the traction direction and position of the cable 8.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
