Description

Technical Field

[0001] The present invention relates to the technical field of steel cable retracting and deploying devices, and particularly relates to a device for preventing and controlling the torsion of the steel cable for retracting and deploying plastic cloth. Background Art

[0002] The traction operation equipment for retracting and deploying the plastic cloth in the plastic pond is related to the task of rain and disaster prevention for the raw salt products. Among them, the traction steel cable connected by the anchor chain rotates during operation due to the torsional force from the rope during use. The steel cable is a wire bundle formed by twisting multiple strands of steel wire around a fiber core or a steel wire core. If the steel cable rotates, it is likely to affect the use of the steel cable.

[0003] The steel cable retracting and deploying device and method with the publication number of CN108439088A disclose a device including a steel cable reel, a transmission rotating shaft, a transmission sprocket set, a torque motor, and a fixed frame. The transmission rotating shaft passes through the steel cable reel, and the steel cable reel is rotatably mounted on the fixed frame through the transmission rotating shaft and is fixedly connected to the transmission rotating shaft. One end of the transmission rotating shaft is connected to the torque motor through the transmission sprocket set. The method includes: when paying out the steel cable, connecting the traction head at the end of the steel cable to the winch, starting the winch to traction the steel cable, starting the torque motor to rotate forward to make the steel cable reel rotate along the steel cable traction direction; when recycling the steel cable, disconnecting the traction head at the end of the steel cable from the winch, starting the torque motor to rotate reversely to make the steel cable reel recycle the steel cable. What it discloses is a device for retracting and deploying the steel cable, and it cannot solve the torsion of the steel cable during the retracting and deploying process. Summary of the Invention

[0004] The technical problem to be solved by the present invention is: the torsion of the steel cable during the retracting and deploying process affects its use.

[0005] To solve the above technical problem, the present invention adopts the following technical solutions:

[0006] First, provide a device for preventing and controlling the torsion of the steel cable for retracting and deploying plastic cloth, including a sliding cable. The sliding cable is distributed along the retracting and deploying direction of the steel cable. A sliding ring is sleeved on the sliding cable. A clamping ring is clamped on the steel cable. A connecting rod is installed on the sliding ring. A locking device is arranged between the connecting rod and the clamping ring. The locking device is used to clamp the clamping ring on the steel cable to prevent the steel cable from twisting. The locking device includes a sleeve. A locking cylinder is sleeved at the connection of the sleeve and the connecting rod. The sleeve is detachably connected to the clamping ring. A push rod passes through the clamping ring. Rotating the locking cylinder can make the push rod clamp on the steel cable.

[0007] Further, the clamping ring includes two semi-circular rings that are rotatably connected. The movable ends of the semi-circular rings are connected by a buckle. A push rod that cooperates with the locking device is radially penetrated on the semi-circular rings.

[0008] Further, the locking device includes a screw rod, which is coaxially arranged with the locking cylinder. The screw rod is connected to the sleeve and the connecting rod through linear bearings. The end of the screw rod contacts the end of the push rod, and the screw rod is threadedly connected to the locking cylinder.

[0009] Further, an extension section is provided on the semi-circular ring, and the push rod is inserted through the extension section. The extension section is in plug-in fit with the sleeve.

[0010] Further, a circular ring is provided between the sleeve and the connecting rod. The outer side of the circular ring is connected to the locking cylinder, and the inner side of the circular ring is threadedly connected to the screw rod.

[0011] Further, a clamping block is elastically connected to the side of the extension section, and a clamping hole is provided at the position corresponding to the clamping block on the sleeve.

[0012] Further, a plurality of clamping holes are provided on the sleeve along its axial direction, and an arc-shaped plate covers the positions corresponding to the clamping holes on the sleeve. An unlocking block adapted to the clamping holes is installed on the arc-shaped plate.

[0013] Further, an annular limiting groove is provided on the side of the sleeve and the connecting rod close to the circular ring. A countersunk bolt is inserted through the locking cylinder at the position corresponding to the limiting groove, and the inner end of the countersunk bolt extends into the limiting groove.

[0014] Further, the locking cylinder is rotationally connected to the sleeve and the connecting rod through a rotary bearing.

[0015] Further, an arc-shaped rod is provided at the inner end of the push rod.

[0016] The present invention has the following beneficial effects: By rotating the locking cylinder, the screw rod can be driven to move, so that the screw rod pushes the push rod to press against the snap ring, thereby pressing the steel cable to prevent it from twisting. During use, only by rotating the locking cylinder in the reverse direction can the snap ring be loosened from the steel cable, which is convenient for moving the device on the steel cable; at the same time, it can be applied to steel cables of different thicknesses, ensuring that the distance between the push rod and the screw rod is not too far before starting to use, making it more convenient to use and adaptable to different situations; at the same time, the setting of the unlocking block also makes the disassembly between the snap ring and the sleeve more convenient, making the connection and disassembly between the snap ring and the slip ring easier.

[0024] In order to better explain the present invention for easy understanding, the present invention will be described in detail below with reference to the accompanying drawings through specific implementation manners.

[0025] It should be noted that all directional indications in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If this specific posture changes, the directional indications will also change accordingly.

[0026] In addition, in the present invention, descriptions such as "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "a plurality" means at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0027] In the present invention, unless otherwise clearly defined and limited, terms such as "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0028] The present invention provides a device for preventing and controlling the torsion of the steel cable for plastic cloth retraction and extension, as Figure 1As described above, it includes a zip line 10, where the zip line 10 is distributed along the winding and unwinding direction of the steel cable 11. The two ends of the zip line 10 are fixed by fixing piles 12. A sliding ring 20 is sleeved on the zip line 10, and a connecting rod 21 is installed on the sliding ring 20. A clamping ring 30 is clamped on the steel cable 11, and the clamping ring 30 is connected to the connecting rod 21. A locking device 40 is arranged between the clamping ring 30 and the connecting rod 21 for clamping the clamping ring 30 on the steel cable 11.

[0029] When connecting the sliding ring 20 and the clamping ring 30, the locking device 40 locks the clamping ring 30 and the steel cable 11. Under the action of the connecting rod 21 and the zip line 10, the steel cable 11 can be prevented from twisting. At the same time, during the winding and unwinding process of the steel cable 11, the sliding ring 20 will move synchronously on the zip line 10, ensuring the normal winding and unwinding of the steel cable 11 on the premise of restricting the twisting of the steel cable 11.

[0030] As Figure 2 shown, the clamping ring 30 includes semi-circular rings 31 that are rotatably connected. One end of the two semi-circular rings 31 is rotatably connected, and the other end is connected by a buckle. When the buckle is locked, the two semi-circular rings 31 form the clamping ring 30. One of the semi-circular rings 31 is connected to the locking device 40, and a push rod 32 is radially penetrated along its radius. An arc-shaped rod 33 is installed at the inner end of the push rod 32. The locking device 40 can push the push rod 32 to move, pressing the steel cable 11 against the other semi-circular ring 31, thereby achieving the effect of clamping the steel cable 11 and preventing the steel cable 11 from twisting. To increase the friction, a rubber pad 34 is arranged on the inner side surface of the semi-circular ring 31 in contact with the steel cable 11.

[0031] As Figure 3 shown, the locking device 40 includes a sleeve 41. The sleeve 41 is arranged at the end of the connecting rod 21. A locking cylinder 42 is sleeved at the connection between the sleeve 41 and the connecting rod 21. The locking cylinder 42 keeps the sleeve 41 and the connecting rod 21 coaxial, and the locking cylinder 42 is rotatably connected to the sleeve 41 and the connecting rod 21 through a rotating bearing 47. A groove 22 is arranged at the end of the connecting rod 21. A coaxial screw 23 is arranged in the locking cylinder 42. The screw 23 penetrates through the sleeve 41 and the groove 22. One end of the screw 23 is connected to the inner side surface of the sleeve 41 through a linear bearing 24, and the other end is also connected to the groove 22 through a linear bearing 24. The linear bearing 24 enables the screw 23 to only move along its axial direction. For a more stable structure, the screw 23 is connected to the groove 22 through a key block (not shown in the figure), ensuring that the screw 22 can only move along its axial direction. A coaxial ring 43 is arranged between the sleeve 41 and the connecting rod 21. The inner side surface of the locking cylinder 42 is fixedly connected to the ring 43, and the inner side surface of the ring 43 is threadedly connected to the screw 23.

[0032] As Figure 5As shown, in the present embodiment, the locking cylinder 42 can be rotated to drive the ring 43 to rotate. The rotation of the ring 43 can drive the screw 23 to move along its axial direction under the action of the thread, and the semi-circular ring 31 is connected to the sleeve 41, so that the push rod 32 is inserted into the sleeve 41. After that, when the screw 23 moves, it can contact the push rod 32. The screw 23 continues to move to press the push rod 32 against the steel cable 11, thereby completing the locking of the steel cable 11.

[0033] like Figure 2 , Figure 3 and Figure 5 As shown, in order to make the connection between the sleeve 41 and the semicircular ring 31 more stable, an extension section 35 is provided at the position of the semicircular ring 31 corresponding to the push rod 32, the push rod 32 is plugged into the extension section 35, the extension section 35 is plugged into the sleeve 41, a clamping block 36 is elastically connected to the side of the extension section 35, and a clamping hole 44 is provided at the position of the sleeve 41 corresponding to the clamping block 36. After the extension section 35 is inserted into the sleeve 41, the clamping block 36 is retracted, and then when the clamping block 36 moves to the clamping hole 44, the clamping block 36 enters the clamping hole 44, at this time, the extension section 35 and the sleeve 41 are fixed, and at this time the screw rod 23 can stably push the push rod 32 to move.

[0034] In order to facilitate the removal of the semicircular ring 31, the position of the sleeve 41 corresponding to the locking hole 44 is covered with an arc plate 45, and the position of the arc plate 45 corresponding to the locking hole 44 is provided with an unlocking block 46 that cooperates with the locking hole 44. The arc plate 45 is elastically connected to the sleeve 41. By pressing the arc plate 45 to make it close to the sleeve 41, the unlocking block 46 enters the locking hole 44, and the locking block 36 in the locking hole 44 can be pushed out. At this time, the extension section 35 can be pulled out from the sleeve 41.

[0035] In actual use, due to the different thickness of the steel cable 11, in order to prevent the screw rod 23 and the push rod 32 from having a large distance or interference, as shown in FIG. Figure 4 , Figure 5 and Figure 6 As shown, the sleeve 41 is provided with a plurality of clamping holes 44 along its axial direction;

[0036] When facing some thinner steel cables 11, the portion of the push rod 32 extending out of the extension section 35 is less, and the extension section 35 can be inserted deeper into the sleeve 41, so that the push rod 32 can be closer to the screw rod 23. It only takes a slight rotation of the locking cylinder 42 to make the screw rod 23 contact with the push rod 32, thereby completing the locking of the steel cable 11.

[0037] When facing some relatively thick steel cables 11, the part of the push rod 32 extending out of the extension section 35 is relatively long. At this time, the extension section 35 can be slightly inserted into the sleeve 41. At this time, it can also ensure that the push rod 32 and the screw rod 23 are relatively close to each other. Only by slightly rotating the locking cylinder 42, the screw rod 23 can also be brought into contact with the push rod 32 to complete the locking of the steel cable 11.

[0038] To make the connection between the sleeve 41 and the connecting rod 21 more stable, annular limiting grooves 48 are provided on the side surfaces of the ends of the sleeve 41 and the connecting rod 21 close to the circular ring 43. Countersunk head screw rods 49 are inserted through the positions on the side surface of the locking cylinder 42 corresponding to the limiting grooves 48. The countersunk head screw rods 49 extend into the limiting grooves 48, ensuring that the connection between the sleeve 41 and the connecting rod 21 is more stable and will not affect the rotation of the locking cylinder 42.

[0039] As Figure 2 shown, in this embodiment, the buckle between the two semi-circular rings 31 includes a T-shaped rod 37. The T-shaped rod 37 is rotatably connected to one end of one of the semi-circular rings 31, and a slot 38 matching the T-shaped rod 37 is provided on the other semi-circular ring 31. When the movable ends of the two semi-circular rings 31 approach, rotate the T-shaped rod 37 to make it cooperate with the slot 38, and the movable ends of the two semi-circular rings 31 can be locked so that they cannot separate by themselves.

[0040] It should be understood that the above description of the specific embodiments of the present invention is only for explaining the technical route and features of the present invention, and its purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. However, the present invention is not limited to the above specific embodiments. Any changes or modifications made within the scope of the claims of the present invention should be covered by the protection scope of the present invention.
