Description

Technical Field

[0001] This utility model relates to the field of cable and wire laying equipment technology, and in particular to a cable and wire laying lead wire device. Background Technology

[0002] Cable guides are auxiliary tools used in various pipelines to guide ropes and lay communication cables, power cables, network cables, and other cables. Existing cable guides mostly use fiberglass cable pullers, whose basic structure typically includes a frame, a winding frame rotatably connected to the frame, and fiberglass tubing wound around the winding frame. In actual use, operators need to manually turn the spokes of the winding frame to rotate it for winding, or directly pull the fiberglass tubing to unwind. This manual operation, especially when winding long or heavy cables, requires considerable physical strength, is very strenuous, significantly increases the operator's workload, and can easily lead to fatigue over long periods. Furthermore, during manual rapid winding, especially near the end of winding, the winding frame may rotate too fast, and the spokes of the winding frame can easily strike the operator's hands during high-speed rotation, posing a safety hazard.

[0003] To address the aforementioned issues, existing technologies urgently need improvement. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a cable and wire laying lead wire device.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a cable and wire laying guide, comprising a frame, a winding frame rotatably connected to the frame via a main shaft, and a cable wound inside the winding frame, and further comprising:

[0006] A locking mechanism is provided on the side wall of the frame to lock the rotation of the take-up frame;

[0007] Friction grooves are provided on the outer surface of the take-up frame;

[0008] Two supports are symmetrically and fixedly connected to the frame below the winding frame, and the ends of the supports are provided with fixing covers;

[0009] A connecting plate is disposed between two fixed covers. A friction plate is provided on one side of the connecting plate. The connecting plate is rotatably connected to the inner walls of the two fixed covers through cylinders on both sides. Two connecting tubes are symmetrically fixedly connected to one side of the connecting plate. The friction plate is sleeved on the surface of the two connecting tubes through two first circular holes. The friction plate is used for frictional engagement with the friction groove. A limit mechanism is provided on the surface of the connecting tube to limit the sliding of the friction plate.

[0010] The foot-operated drive mechanism is used to drive the friction disc to rotate.

[0011] Furthermore, the locking mechanism includes a rotating shaft fixedly connected to the side wall of the frame, a friction ring being rotatably sleeved on the surface of the rotating shaft by a torsion spring, a limit block being fixedly connected to the side wall of the frame, and the friction ring rotating downward to press and rub against the main shaft of the winding frame and abutting against the limit block.

[0012] Furthermore, the friction ring is made of rubber.

[0013] Furthermore, the limiting mechanism includes:

[0014] A clearance opening is provided on the surface of the connecting pipe. A locking block is slidably connected to the inner wall of the clearance opening. An inclined opening is provided on the surface of the locking block. The inclined opening is provided with a first inclined surface and a second inclined surface.

[0015] A pressure block is slidably connected to the inner wall of the connecting tube, one end of which extends to the outside of the connecting tube, and a return spring is fixedly connected between the pressure block and the inner wall of the connecting tube.

[0016] A drive rod is fixedly connected to the end of the pressure block, and the drive rod is provided with an inclined block that is adapted to the first inclined surface and the second inclined surface.

[0017] Furthermore, the limiting mechanism also includes two connecting rods, which are symmetrically fixedly connected to the side wall of the connecting disc, and the friction disc is slidably connected to the two connecting rods.

[0018] Furthermore, the foot pedal drive mechanism includes two foot pedals, which pass through two fixed covers and extend into them before being fixedly connected to the end of the cylinder. Each of the two foot pedals has a pedal plate rotatably connected to its surface.

[0019] Furthermore, the friction groove is an annular groove provided on the outer surface of the winding frame.

[0020] Furthermore, the friction disc has a disc-shaped structure.

[0021] Furthermore, handles are fixedly connected to the side wall of the frame.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] By incorporating a foot-operated drive mechanism, operators can rotate the friction disc using a method similar to riding a bicycle. The friction between the disc and the friction grooves on the winding frame then drives the winding frame to rotate, assisting with manual winding. Compared to the entirely manual cranking or pulling methods of existing technologies, this foot-operated drive significantly reduces the operator's workload, making winding operations easier and less strenuous. It is particularly suitable for scenarios involving long winding times or winding long cables, thus improving work efficiency. Attached Figure Description

[0031] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0032] like Figures 1 to 6 The cable laying guide shown includes a frame 1, a take-up frame 3 rotatably connected to the frame 1 via a main shaft 7, and a cable wound inside the take-up frame 3. It also includes:

[0033] A locking mechanism is installed on the side wall of the frame 1 to lock the rotation of the take-up frame 3;

[0034] Friction grooves 4 are provided on the outer surface of the winding frame 3;

[0035] Two supports are symmetrically and fixedly connected to the frame 1 below the winding frame 3, and the ends of the supports are provided with fixing covers;

[0036] A connecting plate 11 is disposed between two fixed covers. A friction plate 2 is disposed on one side of the connecting plate 11. The connecting plate 11 is rotatably connected to the inner walls of the two fixed covers through cylinders on both sides. Two connecting pipes 13 are symmetrically fixedly connected to one side of the connecting plate 11. The friction plate 2 is sleeved on the surface of the two connecting pipes 13 through two first circular holes. The friction plate 2 is used for frictional engagement with the friction groove 4. A limit mechanism is provided on the surface of the connecting pipe 13 to limit the sliding of the friction plate 2.

[0037] A foot pedal drive mechanism is used to drive the friction disc 2 to rotate.

[0038] The limiting mechanism includes:

[0039] A clearance opening is provided on the surface of the connecting pipe 13. A locking block 17 is slidably connected to the inner wall of the clearance opening. An inclined opening is provided on the surface of the locking block 17, and the inclined opening is provided with a first inclined surface and a second inclined surface.

[0040] The pressure block 14 is slidably connected to the inner wall of the connecting tube 13. One end of the pressure block 14 extends to the outside of the connecting tube 13. A return spring 16 is fixedly connected between the pressure block 14 and the inner wall of the connecting tube 13.

[0041] The drive rod 15 is fixedly connected to the end of the pressure block 14, and the drive rod 15 is provided with an inclined block that is adapted to the first inclined surface and the second inclined surface.

[0042] Compared to existing lead wire machines that primarily rely on manual operation, this invention offers significant advantages. Existing technologies involve laborious winding processes and pose a risk of injury from spokes. This invention, by introducing a foot-operated drive mechanism and friction transmission, shifts the power source for winding from arm strength to leg strength. Leg strength is typically greater than arm strength and can be sustained for a longer period, thus significantly reducing the operator's workload and making the winding process easier and less strenuous. Furthermore, by incorporating a sliding friction disc 2, this invention allows the friction disc 2 to separate from the winding frame 3 during unwinding. At this time, the foot-operated drive mechanism will not rotate with the winding frame 3, effectively preventing the foot pedal 5 from hitting the operator and eliminating the safety hazards of existing technologies. Moreover, by incorporating a locking mechanism, when the operator adjusts the position of the friction disc 2 (engaging or disengaging it with the friction groove 4), the winding frame 3 can be locked first, preventing accidental rotation of the winding frame 3 due to cable elasticity or accidental contact, further improving operational safety. Therefore, this invention significantly enhances operational safety while improving work efficiency.

[0043] The cable and wire laying guide of this utility model can be used to unwind or rewind as needed.

[0044] During the unwinding operation, the friction disc 2 is first pulled to slide it to a position away from the take-up frame 3. At this point, the friction disc 2 separates from the friction groove 4 on the outer surface of the take-up frame 3. Specifically, the pressure block 14 on the sliding mechanism of the friction disc is pressed. This pressure block 14, through the inclined block on the drive rod 15, presses the first inclined surface in the inclined opening, causing the locking block 17 to retract into the connecting tube 13, thus allowing the friction disc 2 to slide along the connecting tube 13 and the connecting rod 12. After sliding into position, the pressure block 14 is released, and the return spring 16 drives the pressure block 14 and the drive rod 15 to reset. During the reset process of the drive rod 15, the inclined block pulls the second inclined surface, causing the locking block 17 to reset. At this point, the locking block 17 extends and abuts against the inner wall of the first circular hole, locking the friction disc 2 in the unwinding position and preventing it from moving towards the take-up frame 3. With the friction disc 2 separated from the friction groove 4, the operator pulls the cable to unwind it, and the winding frame 3 rotates freely on the main shaft 7. However, the foot pedal 5 and the footplate 10 do not rotate with it, thus avoiding collisions with the operator and ensuring the safety of the unwinding operation.

[0045] When rewinding is required, first operate the locking mechanism to lock the rotation of the rewinding frame 3. After locking the rewinding frame 3, press the pressure block 14 again to slide the friction disc 2 towards the rewinding frame 3 until it rubs against the friction groove 4 (rewinding position). After adjustment, release the pressure block 14, and the locking block 17 extends. The extended locking block 17 blocks one side of the friction disc 2, also restricting the sliding of the friction disc 2. At this time, the friction disc 2 is in the rewinding position. Then, release the locking mechanism from the rewinding frame 3 (for example, lift the friction ring 6 to separate it from the main shaft 7). The operator can sit on a nearby stool or small bench, hold the handle 9 (if a handle 9 is provided) with both hands, place both feet on the foot pedal 10, and drive the foot pedal 5 to rotate by alternately stepping on the foot pedal 10. The foot pedal 5 drives the friction disc 2 to rotate through the connecting plate 11. The rotation of the friction disc 2, through the friction force with the friction groove 4 on the outer surface of the rewinding frame 3, drives the rewinding frame 3 to rotate synchronously, thereby realizing the rewinding of the cable. In this process, the foot pedal drive mechanism (foot pedal 5, pedal plate 10, connecting plate 11) converts the reciprocating motion of the foot pedal into the rotational motion of the friction disc 2; the friction transmission mechanism composed of the friction disc 2 and the friction groove 4 transmits the rotational power of the friction disc 2 to the winding frame 3; the locking mechanism (friction ring 6, limit block 8) ensures safe operation when adjusting the position of the friction disc 2. The whole process is labor-saving, efficient and safe.

[0046] As one embodiment of this utility model, the locking mechanism includes a rotating shaft fixedly connected to the side wall of the frame 1. A friction ring 6 is rotatably sleeved on the surface of the rotating shaft by a torsion spring. A limit block 8 is fixedly connected to the side wall of the frame 1. The friction ring 6 rotates downward to press and rub against the main shaft 7 of the winding frame 3 and abuts against the limit block 8.

[0047] Specifically, the locking mechanism locks the main shaft 7 of the take-up frame 3 via a friction ring 6 pivotally connected to the frame 1. The friction ring 6 is normally in the unlocked position under the action of a torsion spring. When it is necessary to lock the take-up frame 3, the operator can press down on the friction ring 6, causing it to rotate around the shaft until its inner surface contacts the outer surface of the main shaft 7 and generates friction. Simultaneously, another part of the friction ring 6 abuts against a limiting block 8 mounted on the frame 1, further restricting the rotation range of the friction ring 6, thereby locking the main shaft 7 and preventing it from rotating freely.

[0048] In one embodiment of this utility model, the friction ring 6 is made of rubber.

[0049] In practice, specifically, the friction ring 6 is designed to be made of rubber, based on its required technical performance for frictional engagement with the main shaft 7 of the winding frame 3. Rubber has a high coefficient of friction, which allows the friction ring 6 to generate sufficient frictional force when pressed into contact with the main shaft 7, thereby reliably locking the rotation of the main shaft 7. Furthermore, rubber also possesses a certain degree of elasticity and wear resistance, which helps the friction ring 6 to better conform to the surface of the main shaft 7, increasing the contact area, improving the friction effect, while reducing wear on the surface of the main shaft 7 and extending the service life of the component.

[0050] As one embodiment of this utility model, the limiting mechanism also includes two connecting rods 12, which are symmetrically fixedly connected to the side wall of the connecting plate 11, and the friction plate 2 is slidably connected to the two connecting rods 12.

[0051] In practice, the function of link 12 is to provide additional support and guidance for the sliding of friction disk 2, ensuring that friction disk 2 remains stable during sliding and does not tilt or jam. The two links 12 are symmetrically arranged, which helps to balance the forces on friction disk 2 during sliding, making the sliding smoother.

[0052] As one embodiment of this utility model, the foot pedal drive mechanism includes two foot pedals 5. The two foot pedals 5 pass through two fixed covers and extend into them before being fixedly connected to the end of the cylinder. A foot plate 10 is rotatably connected to the surface of each of the two foot pedals 5.

[0053] In implementation, the foot pedal 5 can be a metal rod, securely connected to the cylindrical end of the connecting plate 11 via welding, bolting, or other fixing methods to ensure reliable power transmission. The pedal plate 10 can be rotatably connected to the foot pedal 5 via a pin or other means. The fixing cover provides support and protection for the connection between the connecting plate 11 and the foot pedal 5.

[0054] This additional technical feature details the specific structure of the foot-operated drive mechanism. By employing a classic foot pedal structure with two foot levers 5 and a footplate 10, and effectively connecting it to the connecting disc 11 of the drive friction disc 2, a stable, efficient, and ergonomic drive method is formed. Compared to merely describing a "foot-operated drive mechanism" in general terms, this specific structural description makes the technical solution clearer. Furthermore, this alternating foot pedaling method fully utilizes the operator's leg strength to achieve smooth and continuous rotational output, providing a reliable power source for subsequent friction winding.

[0055] In one embodiment of this utility model, the friction groove 4 is an annular groove provided on the outer surface of the winding frame 3.

[0056] During implementation, the annular groove extends along the circumference of the winding frame 3, forming a continuous ring structure. The depth and width of the annular groove can be designed as needed to ensure sufficient contact area and friction with the friction disc 2.

[0057] In one embodiment of this utility model, the friction disk 2 has a disc-shaped structure.

[0058] As one embodiment of this utility model, a handle 9 is fixedly connected to the side wall of the frame 1.

[0059] In practice, the handle 9 is a structure that is easy for the operator to grip, and its shape and size can be designed according to ergonomic principles, such as by making it into a curved tubular structure. The handle 9 is firmly attached to the side wall of the frame 1 by welding, bolting, or other reliable fixing methods. The handle 9 is preferably positioned at a height and location that is convenient for the operator to support when performing foot-operated winding.

[0060] Working principle of this utility model:

[0061] During the unwinding operation, the friction disc 2 is first pulled to slide it to a position away from the take-up frame 3. At this point, the friction disc 2 separates from the friction groove 4 on the outer surface of the take-up frame 3. Specifically, the pressure block 14 on the sliding mechanism of the friction disc is pressed. This pressure block 14, through the inclined block on the drive rod 15, presses the first inclined surface in the inclined opening, causing the locking block 17 to retract into the connecting tube 13, thus allowing the friction disc 2 to slide along the connecting tube 13 and the connecting rod 12. After sliding into position, the pressure block 14 is released, and the return spring 16 drives the pressure block 14 and the drive rod 15 to reset. During the reset process of the drive rod 15, the inclined block pulls the second inclined surface, causing the locking block 17 to reset. At this point, the locking block 17 extends and abuts against the inner wall of the first circular hole, locking the friction disc 2 in the unwinding position and preventing it from moving towards the take-up frame 3. With the friction disc 2 separated from the friction groove 4, the operator pulls the cable to unwind it, and the winding frame 3 rotates freely on the main shaft 7. However, the foot pedal 5 and the footplate 10 do not rotate with it, thus avoiding collisions with the operator and ensuring the safety of the unwinding operation.

[0062] When rewinding is required, first operate the locking mechanism to lock the rotation of the rewinding frame 3. After locking the rewinding frame 3, press the pressure block 14 again to slide the friction disc 2 towards the rewinding frame 3 until it rubs against the friction groove 4 (rewinding position). After adjustment, release the pressure block 14, and the locking block 17 extends. The extended locking block 17 blocks one side of the friction disc 2, also restricting the sliding of the friction disc 2. At this time, the friction disc 2 is in the rewinding position. Then, release the locking mechanism from the rewinding frame 3 (for example, lift the friction ring 6 to separate it from the main shaft 7). The operator can sit on a nearby stool or small bench, hold the handle 9 (if a handle 9 is provided) with both hands, place both feet on the foot pedal 10, and drive the foot pedal 5 to rotate by alternately stepping on the foot pedal 10. The foot pedal 5 drives the friction disc 2 to rotate through the connecting plate 11. The rotation of the friction disc 2, through the friction force with the friction groove 4 on the outer surface of the rewinding frame 3, drives the rewinding frame 3 to rotate synchronously, thereby realizing the rewinding of the cable.

[0063] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope. All such changes and modifications fall within the scope of protection claimed by this utility model, which is defined by the appended claims and their equivalents.
