Description

Technical Field

[0001] This utility model belongs to the field of workshop maintenance tools, specifically relating to a cable laying device with automatic straightening. Background Technology

[0002] The core function of the cigarette factory's power workshop is to provide continuous, stable, and compliant energy and utility support for key production processes such as tobacco processing, cigarette making and packaging, and finished product warehousing, as well as office and auxiliary facilities. In practice, this involves drawing high-voltage electricity from the municipal power grid, stepping it down, and distributing it to various production workshops and auxiliary facilities; emergency generators and UPS systems ensure short-term power supply to critical equipment (such as control systems and fire-fighting equipment) during power outages. To support power supply and maintain close coordination with other workshops in the cigarette factory, daily maintenance requires the laying of cables for power supply and communication. To ensure the quality of cable laying and reduce manual labor, cable laying devices are needed during the cable laying process.

[0003] Current wire laying equipment lacks a dedicated straightening mechanism, and manual straightening is time-consuming and easily damages the wires, resulting in poor equipment adaptability. Utility Model Content

[0004] The purpose of this utility model is to provide a cable laying device with automatic straightening to solve the problems mentioned in the background art, such as the time-consuming and easily damaged wires due to manual straightening during cable laying, and the poor equipment adaptability.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A cable laying device with automatic straightening includes a trolley body and a winding bracket mounted on the trolley body, the winding bracket being used to mount a cable laying frame;

[0007] The trolley body is also equipped with a first straightening roller group and a composite straightening assembly, with the first straightening roller group located between the winding bracket and the composite straightening assembly;

[0008] The composite straightening assembly includes a second straightening roller group, a mounting ring, and a guide. The mounting ring is slidably mounted on the trolley body, and the sliding direction of the mounting ring is parallel to the length direction of the first straightening roller group. The second straightening roller group and the guide are respectively movably mounted on both sides of the mounting ring, with the second straightening roller group located on the side of the mounting ring closer to the first straightening roller group.

[0009] A power mechanism is mounted on the mounting ring, and the power mechanism is connected to the second straightening roller group. The length direction of the second straightening roller group is not coplanar with the length direction of the first straightening roller group. The cable wound on the pay-off frame passes sequentially through the first straightening roller group, the second straightening roller group, and the guide. After being straightened by the first and second straightening roller groups, it is oriented and guided by the guide. When the power mechanism drives the second straightening roller group to deflect on the mounting ring, the second straightening roller group twists the cable. The guide is adapted to the deflection of the second straightening roller group to guide the cable to achieve composite straightening.

[0010] With the above structural design, when the cable is laid out via the cable laying frame, the free end of the cable passes sequentially through the first straightening roller group, the second straightening roller group, and the guide. The first and second straightening roller groups straighten the cable, while the guide provides directional guidance. Furthermore, the second straightening roller group can simultaneously apply a torsional force to the cable, reducing cable bending. The guide's posture can be automatically adjusted to adapt to the cable's output direction. The geothermal straightening roller group is not limited to the vertical direction; it can be vertically offset to the right or left, exhibiting high adaptability and achieving automatic straightening during cable laying.

[0011] Furthermore, a rotating ring is rotatably mounted coaxially on the side of the mounting ring closest to the first straightening roller group;

[0012] Two arc-shaped adjusting blocks are mounted opposite each other on the rotating ring, and the second straightening roller group is installed between the two arc-shaped adjusting blocks;

[0013] The power mechanism is connected to the rotating ring drive.

[0014] Through the above structural design, the attitude adjustment of the second straightening roller group can be completed by the power mechanism; while adjusting the second straightening roller group, the attitude of the guide is also adjusted in the opposite direction.

[0015] Furthermore, the rotating ring has an installation platform at the corresponding position of the arc-shaped adjusting block. Both ends of the installation platform are provided with limit blocks, and each of the two limit blocks on the same installation platform is equipped with a limit end rod. The arc-shaped adjusting block is engaged between the two limit end rods and abuts against the installation platform.

[0016] Through the above structural design, the arc-shaped adjusting block can be detached and installed via the limiting end rod, making it convenient to replace the second straightening roller group to adapt to cables of different specifications.

[0017] Furthermore, an internal gear ring is installed on the inner wall of the rotating ring, the power mechanism is a forward and reverse motor, and the output shaft of the forward and reverse motor is equipped with a drive gear that meshes with the internal gear ring.

[0018] Furthermore, on the side of the mounting ring away from the first straightening roller group, two or more mounting rods are mounted in a circumferential array, each mounting rod is hinged to a connecting rod, and the free ends of all the connecting rods are hinged to a guide.

[0019] Furthermore, the guide includes a mounting shell and a guide ball; the mounting shell is hinged to the free end of the connecting rod, the guide ball is rotatably mounted in the mounting shell, and a through channel is provided in the center of the guide ball; the mounting shell has a clearance hole corresponding to the position of the through channel.

[0020] Furthermore, a support frame is installed on the trolley body, and the support frame is used to install the first straightening roller group.

[0021] Furthermore, a counter mounting plate extends to one side of the support frame, and a counter is mounted on the counter mounting plate. The first straightening roller group includes two opposing first straightening rollers, one of which has a synchronous counting wheel that matches the counter mounted on its roller shaft end.

[0022] Through the above structural design, the cable length can be counted while the cable is being laid out. The structure is compact and highly automated.

[0023] Furthermore, vertical grooves are provided at both ends of the support frame, and a top limiting block, two intermediate limiting blocks, and a bottom limiting block are slidably installed in the vertical grooves; elastic elements are installed between the top end of the top limiting block and the vertical groove, between the two intermediate limiting blocks, and between the bottom end of the bottom limiting block and the vertical groove; two first straightening rollers are rotatably installed between the top limiting block and the corresponding intermediate limiting block, and between the bottom limiting block and the corresponding intermediate limiting block; all the elastic elements can undergo elastic deformation when the cable passes through the first straightening roller group to adapt to the cable feeding frame.

[0024] Through the above structural design, when laying cables, the defects of conventional cable laying equipment, such as the inability to adjust the straightening force and poor equipment adaptability, can be overcome; it can better adapt to the cable laying frame and protect the cable's protective layer.

[0025] The utility model adopting the above technical solution has the following advantages:

[0026] In this application, when the cable is unloaded through the cable unloading frame, the free end of the cable passes through the first straightening roller group, the second straightening roller group, and the guide in sequence, undergoing two straightening operations and one guidance operation. The second straightening roller group can be driven by a power mechanism, which adds a torsional force while straightening the cable to reduce the residual amount of twisting left when the cable is wound up. The posture of the guide can be freely changed or adjusted before the cable is unloaded.

[0027] The straightening of the second straightening roller group is not limited to the vertical direction. The second straightening roller group can deflect counterclockwise or clockwise in the original straightening direction to twist the cable. The deflection angle is small, which can eliminate or reduce the twisting defects left over when the cable is wound up. It has high adaptability and realizes automatic straightening when the cable is unwound.

[0028] While laying cables, a counter is used to count the length of the laid cables. The structure is compact and highly automated. Furthermore, the overall structure is simple, low in cost, and highly practical. Attached Figure Description

[0041] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description. Implementations not shown or described in the drawings are forms known to those skilled in the art. Furthermore, directional terms mentioned in the embodiments, such as "up," "down," "top," "bottom," "left," "right," "front," and "back," are only for reference to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0042] like Figures 1-6As shown, an embodiment of the present invention provides a cable unloading device with automatic straightening, comprising a trolley body 1 and a winding bracket 11 mounted on the trolley body 1, the winding bracket 11 being used to mount an unloading frame 2; the bottom of the trolley body 1 is equipped with movable wheels, which can drive the cable unloading counting device to move; a first straightening roller group 3 and a composite straightening assembly 4 are also mounted on the trolley body 1, the first straightening roller group 3 being located between the winding bracket 11 and the composite straightening assembly 4; the composite straightening assembly 4 includes a second straightening roller group 41, a mounting ring 42, and a guide 43, the mounting ring 42 being slidably mounted on the trolley body 1, the sliding direction of the mounting ring 42 being parallel to the length direction of the first straightening roller group 3; the second straightening roller group 41 and the guide 43 are respectively movably mounted on the trolley body 1. The second straightening roller group 41 is located on both sides of the mounting ring 42, closer to the first straightening roller group 3. A power mechanism is installed on the mounting ring 42, which is connected to the second straightening roller group 41. The length direction of the second straightening roller group 41 is not coplanar with the length direction of the first straightening roller group 3. The cable wound on the pay-off frame 2 passes through the first straightening roller group 3, the second straightening roller group 41 and the guide 43 in sequence. After being straightened by the first straightening roller group 3 and the second straightening roller group 41, it is guided by the guide 43. When the second straightening roller group 41 is deflected on the mounting ring 42 by the power mechanism, it twists the cable, reducing the residual amount of twisting left when the cable is wound. Then the cable is led out through the guide, realizing composite straightening. Thus, when the cable is laid out via the cable laying frame 2, the free end of the cable passes sequentially through the first straightening roller group 3, the second straightening roller group 41, and the guide 43. After passing through, the cable has already been straightened. Furthermore, the straightening posture of the second straightening roller group 41 can be adjusted, not limited to the vertical direction. The second straightening roller group 41 can be driven to deflect on the mounting ring 42, and the guide 43 adaptively guides the cable, adapting to the deflection of the second straightening roller group 41. This high adaptability achieves automatic straightening during cable laying. In practice, the first straightening roller group 3 is horizontally positioned and includes two opposing first straightening rollers 31. The distance between the two first straightening rollers 31 can be flexibly set as needed. The second straightening roller group 41 can be installed in a more vertical direction; the second straightening roller group 41 includes two opposing second straightening rollers; the distance between the two second straightening rollers can be flexibly set as needed.

[0043] In fact, a groove 16 is provided on the trolley body 1; bearing seats 14 are fixed on both sides of the groove 16 for mounting the lead screw 15; the lead screw 15 is installed along the length direction of the groove 16; the lead screw 15 is threadedly connected to the mounting ring 42; more specifically, the lead screw 15 is threadedly connected to the slider 44 connected to the mounting ring 42. An adjusting motor 17 is fixedly installed on the trolley body 1; the output shaft of the adjusting motor 17 is connected to the lead screw 15 to drive the lead screw 15 to rotate; this realizes the reciprocating adjustment of the composite straightening component 4 along the width direction of the trolley body 1, which has high adaptability to wire feeding and also avoids adverse wear on the cable's protective layer. A push rod 13 is fixedly connected to the trolley body 1; the device can be easily pushed by the push rod 13. A drive wheel is installed on the shaft of the wire feeding frame 2, and the drive wheel is connected to a motor via a belt; the motor can be installed on the ground or on the trolley body 1. Wire feeding is achieved by driving the wire feeding frame 2 to rotate by the motor; this can improve wire feeding efficiency.

[0044] In this embodiment, a support frame 12 is fixed on the trolley body 1, and two opposing first straightening rollers 31 are rotatably mounted on the support frame 12 via bearings; the length direction of the first straightening rollers 31 is parallel to the width direction of the trolley body 1.

[0045] In this embodiment, both ends of the support frame 12 are provided with vertical grooves. A top limiting block 33, two intermediate limiting blocks 34 and a bottom limiting block 35 are slidably installed in the vertical grooves. Elastic elements are installed between the top of the top limiting block 33 and the vertical groove, between the two intermediate limiting blocks 34 and between the bottom of the bottom limiting block 35 and the vertical groove. Two first straightening rollers 31 are rotatably installed between the top limiting block 33 and the corresponding intermediate limiting block 34, and between the bottom limiting block 35 and the corresponding intermediate limiting block 34. All elastic elements can undergo elastic deformation when the cable passes through the first straightening roller group 3 to adapt to the cable feeding frame 2 feeding the cable.

[0046] The elastic components include a top spring installed between the top end of the top limiting block 33 and the vertical groove, an intermediate spring between the two intermediate limiting blocks 34, and a bottom spring between the bottom end of the bottom limiting block 35 and the vertical groove. In addition, the preload of the top spring can be adjusted by the top adjusting screw 32 threaded to the top of the support frame 12, and the preload of the bottom spring can be adjusted by the bottom adjusting screw 36 at the bottom.

[0047] In fact, the top adjusting screw 32 and the bottom adjusting screw 36 can be replaced with adjusting air rods, which can automatically adjust the preload and extension of the top and bottom springs.

[0048] In this embodiment, a rotating ring 45 is rotatably mounted coaxially on the side of the mounting ring 42 near the first straightening roller group 3; two arc-shaped adjusting blocks 46 are mounted opposite each other on the rotating ring 45, and the second straightening roller group 41 is installed between the two arc-shaped adjusting blocks 46; a power mechanism fixedly mounted on the mounting ring 42 is connected to the rotating ring 45 for transmission. The attitude adjustment of the second straightening roller group 41 can be accomplished by the power mechanism. In practice, the outer diameter of the rotating ring 45 is smaller than that of the mounting ring 42. A limiting ring groove is machined on the inner wall of the mounting ring 42, and the rotating ring 45 is slidably mounted within the limiting ring groove to achieve rotatable installation. In some scenarios of this embodiment, the two arc-shaped adjusting blocks 46 are fixedly mounted on the rotating ring 45; the two second straightening rollers are rotatably mounted between the two arc-shaped adjusting blocks 46 via roller shafts; the cable passes between the two second straightening rollers and then exits through the center of the guide 43.

[0049] In this embodiment, an internal gear ring 49 is installed on the inner wall of the rotating ring 45. The internal gear ring 49 is an incomplete gear ring. The power mechanism is a forward and reverse motor. A fixing plate 411 is fixedly connected inside the mounting ring 42, and the forward and reverse motor is fixed on the fixing plate 411. The output shaft of the forward and reverse motor is equipped with a drive gear 410 that meshes with the internal gear ring 49. The forward and reverse motor drives the incomplete gear ring to deflect through the drive gear 410, thereby causing the rotating ring 45 to deflect. It should be noted that the deflection amplitude of the incomplete gear ring is small and does not need to complete a full rotation.

[0050] In this embodiment, the rotating ring 45 has a mounting platform at the corresponding position of the arc-shaped adjusting block 46. Limiting blocks 48 are provided at both ends of the mounting platform. Each of the two limiting blocks 48 on the same mounting platform is equipped with a limiting end rod 47. The arc-shaped adjusting block 46 is engaged between the two limiting end rods 47 and abuts against the mounting platform. In practice, the deflection angle of the arc-shaped adjusting block 46 can be set to -15° to 15° as needed; this improves the adaptability to the cable laying position on the cable laying frame 2 during the second straightening. In practice, the limiting end rod 47 and the limiting block 48 can be connected by a snap-fit ​​or threaded connection; the limiting end rod 47 can be straight or arc-shaped.

[0051] In this embodiment, three mounting rods 413 are mounted in a circular array on the side of the mounting ring 42 away from the first straightening roller group 3. Each mounting rod 413 is hinged to a connecting rod 412, and the free ends of all the connecting rods 412 are hinged to the guide 43.

[0052] The guide 43 includes a mounting shell 431 and a guide ball 432. The mounting shell 431 is hinged to the free end of the connecting rod 412. The guide ball 432 is rotatably mounted in the mounting shell 431, and a through channel is formed in the center of the guide ball 432. A clearance hole is formed in the mounting shell 431 corresponding to the through channel. In practice, some elastic rubber balls can be filled inside the mounting shell 431 to support the guide ball 432, allowing it to suspend. Alternatively, several spring plates can be circumferentially connected inside the mounting shell 431, allowing the guide ball 432 to rotate omnidirectionally through the limiting action of the spring plates. Connecting ears extend from the outer wall of the mounting shell 431, and holes for connection, enclosure, and fixation are machined on the connecting ears. When the mounting shell 431 is not offset, the guide ball 432 has the function of guiding the cable.

[0053] In practice, the guide ball 432 can be composed of two identical hemispheres or three identical arc-shaped spherical blocks. The through channel is a smooth arc-shaped channel that is larger at both ends and smaller in the middle. The connecting rod 412 can also be a two-way telescopic rod, which limits the guide 43 and provides the guide 43 with a function of displacement in multiple directions, adapting to the passage of cables from different laying positions and protecting the cable's protective layer.

[0054] In this embodiment, since the slide groove 16 on the trolley body 1 is slidably connected to the slider 44, one of the mounting rods 413 is replaced by the slider 44.

[0055] In fact, with Figure 3 For example, the cable passes through the second straightening roller and exits through the guide ball 432 of the guide 43; the arc-shaped adjusting block 46 above the second straightening roller is offset by the rotating ring 45, which can reduce the "memory bending" remaining after the cable is released and achieve automatic straightening; no manual straightening is required and the insulation layer is not easily damaged.

[0056] In this embodiment, a counter mounting plate 122 extends to one side of the support frame 12, and a counter 5 is mounted on the counter mounting plate 122. The first straightening roller group 3 includes two opposing first straightening rollers 31, one of which has a synchronous counting wheel 51 matched with the counter 5 mounted on its roller shaft end. The synchronous counting wheel 51 rotates in tandem with the first straightening roller 31, and the counter 5 counts once for each revolution of the synchronous counting wheel 51. Through the above structural design, the length of the cable is counted while the cable is being laid out, resulting in a compact structure and a high degree of automation.

[0057] In this embodiment, the counter 5 is connected to a PLC controller with a touch screen to process and display the count; the counter 5 and the PLC controller are existing technologies. In fact, a camera mounting plate is connected to the support frame 12, and a camera mounting hole 121 is centrally located on the camera mounting plate for mounting the camera; the images captured by the camera can be transmitted to the PLC controller. The PLC controller performs real-time analysis of the cable laying status of the cable laying frame 2; and outputs control commands based on the analysis results; controlling the forward and reverse motors and adjusting the operation of motor 17.

[0058] In fact, for the regulating motor 17 and the forward and reverse motors, the power supply can be configured according to actual needs; a generator can be used, or the AC power of the municipal power grid can be connected, and it can be controlled through a conventional distribution cabinet.

[0059] The working principle of the cable laying device with automatic straightening in this embodiment is as follows:

[0060] Before laying the line, move the trolley body 1 to the appropriate position and brake it; configure the power supply for the adjusting motor 17 and the forward and reverse motors;

[0061] During the unwinding process, the unwinding frame 2 with the wound cable is installed on the winding bracket 11; the first straightening roller 31 has been installed on the support frame 12, and the distance between the two first straightening rollers 31 has been adjusted; the second straightening roller is installed on the rotating ring 45 through the arc-shaped adjusting block 46; the mounting hole position of the second straightening roller on the arc-shaped adjusting block 46 has been preset, that is, the distance between the two second straightening rollers has been adjusted.

[0062] During the unwinding process, the free end of the cable passes sequentially between two first straightening rollers 31 and between two second straightening rollers, and then exits through the guide ball 432; it is straightened once by the two first straightening rollers 31 and then straightened a second time by the two second straightening rollers; while the second straightening rollers are straightening, the rotating ring 45 can be controlled to deflect, and the deflection of the rotating ring 45 twists the cable, reducing the amount of twisting left when the cable is wound up;

[0063] As the free end of the cable passes between the two first straightening rollers 31, the elastic extension and contraction of the top spring, middle spring, and bottom spring change according to the position of the cable in the horizontal height, adapting to the constantly changing position of the cable release; then it passes between the second straightening rollers; based on the straightening of the original second straightening rollers, the rotation of the rotating ring 45 applies a deflection of the arc-shaped adjusting block 46, and the directional guide 43, so as to better eliminate the memory bending of the cable after it is released.

[0064] It is understandable that the rotating ring 45 may not need to be adjusted for deflection; then, the two second straightening rollers still have the straightening capability to cooperate with the two first straightening rollers; and the guide 43 guides the wire feeding; the overall structure is simple, low in cost, and highly practical.

[0065] The above provides a detailed description of the cable laying device with automatic straightening provided by this utility model. The specific embodiments are described only to aid in understanding the method and core concept of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
