Description

Technical Field

[0001] This utility model belongs to the technical field of cable processing equipment, and specifically relates to an emergency stop device for cable strand filling rope equipment. Background Technology

[0002] The inner filling layer of the cable needs to be filled with filler rope. The filler rope needs to be stranded using a stranding machine during production. However, the existing stranding machine does not have an emergency stop structure, which can easily affect the winding effect of the cable filler rope.

[0003] Chinese patent CN202320916052.8 discloses a pneumatic brake device for a cable filling rope stranding machine, including a base plate, two stranding plates on the top of the base plate, multiple stranding holes on the right side wall of both stranding plates, a fixing plate on the top of the base plate, a through hole on the right side wall of the fixing plate, a take-up roller sleeved on the outer wall of the main shaft, a brake disc sleeved on the outer wall of the main shaft, a pneumatic brake on the brake disc, a high-pressure air pipe connected to the air inlet end of the pneumatic brake, a solenoid valve on the right side wall of the mounting plate, one end of the solenoid valve connected to the high-pressure air pipe, and a relay and a stop button on the right side wall of the mounting plate.

[0004] However, when existing cable filling rope stranding machines stop, the lack of a braking device causes the drive shaft to continue running for a period of time due to the mechanical inertia generated during operation. This prevents the machine from stopping immediately and easily leads to excess wire overflow or tangling. This not only affects the appearance of the product and wastes wire, but also requires workers to spend time and effort to clean up the mess.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes an emergency stop device for cable strand filling rope equipment to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to an emergency stop device for a cable strand filling rope equipment, comprising a fixed frame, on which a limit component and a retraction component are respectively provided, and a rotating shaft is rotatably connected to the inner side of the fixed frame, and a take-up roller is connected to the surface of the rotating shaft.

[0009] The surface of the fixing frame is connected to four fixing blocks, and the inner side of each of the four fixing blocks is rotatably connected to two wear-resistant rings. The surface of the rotating shaft is connected to two connecting rings, and the surface of each of the two connecting rings is connected to a silicone ring.

[0010] The surface of the limiting component is connected to the surface of the fixing frame to drive the limiting component to perform elastic lifting and lowering movements in the vertical direction;

[0011] The surface of the shrinking component is connected to the surface of the fixing frame to fit against the silicone ring and limit the position of the take-up roller.

[0012] Furthermore, the limiting assembly includes four drive sources, four connecting rods, and four composite expansion springs. The four drive sources are all disposed on the surface of the fixed frame. The power output ends of the four drive sources are all connected to the limiting rods. The inner sides of the four connecting rods are respectively engaged with the surfaces of the four limiting rods. The bottom ends of the four connecting rods are all connected to reinforcing rings. The surfaces of the four reinforcing rings are all connected to silicone collars. The four composite expansion springs are respectively sleeved on the outer sides of the four connecting rods.

[0013] Furthermore, the four silicone collars are symmetrically arranged in pairs on the upper and lower sides of the horizontal center line of the corresponding silicone ring.

[0014] Furthermore, the retraction assembly includes four fixed plates and four retraction springs. The four fixed plates are all disposed on the surface of the fixed frame. Two reinforcing rods are connected between every two fixed plates. Two reinforcing plates are slidably connected to the surface of each fixed plate. The surfaces of every two reinforcing plates are respectively connected to the surface of each reinforcing ring. Each retraction spring is respectively sleeved on the outside of each reinforcing rod.

[0015] Furthermore, each of the contraction springs has its two ends connected to the surface of each pair of reinforcing plates.

[0016] Furthermore, both ends of each of the composite expansion springs are connected to the surface of each of the reinforcing rings and the surface of each of the fixing plates, respectively.

[0017] Furthermore, the surfaces of the four connecting rods are slidably connected to the inner sides of the four fixing plates, respectively.

[0018] Furthermore, the surface of each wear-resistant ring is slidably attached to the surface of the take-up roller.

[0019] This utility model has the following beneficial effects:

[0020] This invention uses a drive source to separate the limiting lever from the connecting rod, allowing the corresponding silicone collar to rapidly pop out under the expansion action of the composite expansion spring and the contraction action of the contraction spring. This generates a symmetrical up-and-down squeezing force on the silicone ring. The dual pressure and the strong friction between the silicone collar and the silicone ring facilitate an emergency stop for the rotating shaft and the take-up roller, preventing quality problems in the appearance of the cable filler rope. The wear-resistant ring slides and adheres to the take-up roller, improving the smoothness of the take-up roller's rotation while also reducing wear.

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

[0033] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0034] Please see Figures 1-7 As shown, this utility model is an emergency stop device for a cable strand filling rope equipment, including a fixed frame 1. A limit assembly 2 and a retraction assembly 3 are respectively installed on the fixed frame 1. A rotating shaft 4 is rotatably connected to the inner side of the fixed frame 1, and a take-up roller 5 is connected to the surface of the rotating shaft 4.

[0035] The surface of the fixing frame 1 is connected to four fixing blocks 6, and the inner sides of the four fixing blocks 6 are rotatably connected to two wear-resistant rings 7. The surface of the rotating shaft 4 is connected to two connecting rings 8, and the surface of the two connecting rings 8 is connected to silicone rings 9.

[0036] The surface of the limiting component 2 is connected to the surface of the fixing frame 1 so as to drive the limiting component 2 to perform elastic lifting and lowering motion in the vertical direction;

[0037] The surface of the shrinking component 3 is connected to the surface of the fixing frame 1 so as to fit against the silicone ring 9 and limit the position of the take-up roller 5.

[0038] First, the cable filler rope is stranded into multiple strands using a cable stranding machine. Then, one end of the stranded rope is fixed to the take-up roller 5. Next, the drive structure drives the rotating shaft 4 to rotate the take-up roller 5 to wind up the cable filler rope during the stranding process. When it is necessary to stop the rotating shaft 4 and the take-up roller 5 as a whole, the drive limit component 2 operates, causing the limit component 2 to be tightly attached to the silicone ring 9 on the connecting ring 8 under its own expansion and contraction of the contraction component 3. This achieves an emergency stop of the rotating shaft 4 and the take-up roller 5 through strong friction, preventing the rotating shaft 4 and the take-up roller 5 from failing to stop in time and avoiding quality problems in the appearance of the cable filler rope. The wear-resistant ring 7 slides and adheres to the take-up roller 5, which improves the smoothness of the rotation of the take-up roller 5 and also reduces wear.

[0039] The expansion of the limiting component 2, combined with the contraction of the shrinking component 3, facilitates the generation of symmetrical up-and-down squeezing forces on the silicone ring 9. The dual pressure and the strong friction between the limiting component 2 and the silicone ring 9 facilitate the emergency stop of the rotating shaft 4 and the take-up roller 5, thus avoiding quality problems in the appearance of the cable filler rope. The wear-resistant ring 7 slides and adheres to the take-up roller 5, which improves the smoothness of the rotation of the take-up roller 5 and also reduces wear.

[0040] In one embodiment, the limiting component 2 includes four drive sources 21, four connecting rods 23, and four composite expansion springs 26. The four drive sources 21 are all disposed on the surface of the fixing frame 1. The power output ends of the four drive sources 21 are all connected to the limiting rods 22. The inner sides of the four connecting rods 23 are respectively engaged with the surfaces of the four limiting rods 22. The bottom ends of the four connecting rods 23 are all connected to the reinforcing rings 24. The surfaces of the four reinforcing rings 24 are all connected to the silicone collars 25. The four composite expansion springs 26 are respectively sleeved on the outer sides of the four connecting rods 23.

[0041] First, the cable filler rope is stranded into multiple strands using a cable stranding machine. Then, one end of the stranded rope is fixed to the take-up roller 5. Next, a drive structure drives a rotating shaft 4 to rotate the take-up roller 5 and wind up the cable filler rope during the stranding process. When an emergency stop is required for the rotating shaft 4 and the take-up roller 5, four drive sources 21 simultaneously drive the limit levers 22 to retract inwards. At this time, each connecting rod 23 loses the locking and limiting effect of its corresponding limit lever 22. Then, under the pushing action of the corresponding composite expansion spring 26, each connecting rod 23 causes the reinforcing ring 24 and the silicone collar 25 to rapidly pop out, thus separating every two silicone collars 25. Do not apply symmetrical clamping force to the surface of each silicone ring 9. At this time, the contraction action of the shrinking component 3 will drive the symmetrical silicone collars 25 to approach each other. Then, the double force of the composite expansion spring 26 and the shrinking component 3 will improve the tightness of the silicone collar 25 and the silicone ring 9. The friction force of the silicone collar 25 rapidly popping out and sticking to the silicone ring 9 will play a role in stopping the silicone ring 9, thereby avoiding the situation where the rotating shaft 4 and the take-up roller 5 cannot stop in time, and avoiding quality problems in the appearance of the cable filling rope. The wear-resistant ring 7 slides and sticks to the take-up roller 5, which improves the smoothness of the rotation of the take-up roller 5 and also reduces wear.

[0042] The drive source 21 drives the limit lever 22 to separate from the connecting rod 23, which facilitates the rapid ejection of the corresponding silicone collar 25 under the expansion action of the corresponding composite expansion spring 26 and the contraction action of the shrinking component 3. This generates a symmetrical up-and-down squeezing force on the silicone ring 9. The double pressure and the strong friction between the silicone collar 25 and the silicone ring 9 facilitate the emergency stop of the rotating shaft 4 and the take-up roller 5, avoiding quality problems in the appearance of the cable filler rope. The wear-resistant ring 7 slides and adheres to the take-up roller 5, which improves the smoothness of the rotation of the take-up roller 5 and also reduces wear.

[0043] In one embodiment, the four silicone collars 25 are symmetrically arranged in pairs on the upper and lower sides of the horizontal center line of the corresponding silicone ring 9, so that the squeezing force generated from the upper and lower sides can generate a frictional force for sudden stop on the silicone ring 9.

[0044] In one embodiment, the retraction assembly 3 includes four fixing plates 31 and four retraction springs 34. The four fixing plates 31 are all disposed on the surface of the fixing frame 1. Two reinforcing rods 32 are connected between every two fixing plates 31. Two reinforcing plates 33 are slidably connected to the surface of each fixing plate 31. The surfaces of every two reinforcing plates 33 are respectively connected to the surface of each reinforcing ring 24. Each retraction spring 34 is respectively sleeved on the outside of each reinforcing rod 32, thereby facilitating the silicone collar 25 to apply double pressure to the silicone ring 9, which improves the emergency stopping effect of the silicone ring 9.

[0045] In one embodiment, for the aforementioned retraction spring 34, each of the two ends of the retraction spring 34 is connected to the surface of each of the two reinforcing plates 33, thereby facilitating the increase of the pressure exerted by the retraction spring 34 on the silicone collar 25.

[0046] In one embodiment, for the aforementioned composite expansion spring 26, both ends of each composite expansion spring 26 are connected to the surface of each reinforcing ring 24 and the surface of each fixing plate 31, respectively, so that the composite expansion spring 26 can drive the silicone collar 25 and the reinforcing ring 24 to pop out rapidly and contact the silicone ring 9, thereby improving the effect of emergency stopping of the silicone ring 9.

[0047] In one embodiment, for the connecting rods 23, the surfaces of the four connecting rods 23 are slidably connected to the inner sides of the four fixing plates 31, thereby facilitating the improvement of the stability of the movement of the connecting rods 23.

[0048] In one embodiment, for the wear-resistant ring 7, the surface of each wear-resistant ring 7 is slidably attached to the surface of the take-up roller 5, thereby improving the smoothness of the rotation of the take-up roller 5 while reducing wear.

[0049] In summary, using the above-mentioned technical solution of this utility model, the cable filler rope is first stranded into multiple strands using a cable stranding machine. Then, one end of the stranded rope is fixed to the take-up roller 5. Next, the drive structure drives the rotating shaft 4 to rotate the take-up roller 5 and wind up the cable filler rope during the stranding process. When an emergency stop is required for the rotating shaft 4 and the take-up roller 5, the four drive sources 21 operate simultaneously to synchronously drive the limit lever 22 to retract inwards. At this time, each connecting rod 23 loses the locking and limiting effect of its corresponding limit lever 22. Then, under the pushing action of the corresponding composite expansion spring 26, each connecting rod 23 will cause the reinforcing ring 24 and the silicone collar 25 to rapidly pop out, thereby causing the corresponding reinforcing ring 24 and the silicone collar 25 to respectively generate symmetrical clamping forces on the surface of the corresponding silicone ring 9. Simultaneously, the corresponding contraction spring... The contraction of spring 34 will cause the corresponding reinforcing plate 33 to approach, thereby causing the silicone collar 25 connected to the reinforcing plate 33 to approach. Then, the combined force of the composite expansion spring 26 and the contraction spring 34 will improve the tightness of the silicone collar 25 and the silicone ring 9. The friction force of the silicone collar 25 rapidly popping out and adhering to the silicone ring 9 will provide a positioning function for the silicone ring 9 to stop quickly, thereby preventing the rotating shaft 4 and the take-up roller 5 from failing to stop in time and avoiding quality problems in the appearance of the cable filling rope. If it is necessary to separate the silicone collar 25 and the silicone ring 9, simply pull the connecting rod 23 to make it correspond to the limit lever 22, and then drive the limit lever 22 and the connecting rod 23 to re-engage through the drive source 21. The wear-resistant ring 7 slides and adheres to the take-up roller 5, which improves the smoothness of the rotation of the take-up roller 5 and also reduces wear.

[0050] Through the above technical solution, the limiting lever 22 is driven by the driving source 21 to separate from the connecting rod 23, so that the corresponding silicone collar 25 can be rapidly ejected under the expansion action of the corresponding composite expansion spring 26 and the contraction action of the contraction spring 34, thereby generating a symmetrical up and down squeezing force on the silicone ring 9. Through the double pressure and the strong friction between the silicone collar 25 and the silicone ring 9, it is easy to stop the rotating shaft 4 and the take-up roller 5, avoiding quality problems in the appearance of the cable filling rope. The wear-resistant ring 7 slides and adheres to the take-up roller 5, which improves the smoothness of the rotation of the take-up roller 5 and also reduces wear.
