Description

Technical Field

[0001] This application belongs to the field of steel strand technology, and more specifically, relates to a winding drum for winding steel strand. Background Technology

[0002] Steel strand, a high-strength metal product made of multiple strands of steel wire, is widely used in many fields such as construction engineering, bridge construction, power transmission, and oil extraction due to its excellent tensile strength, fatigue resistance, and good flexibility. The inherent characteristics of steel strand—long length, heavy weight, and smooth surface—necessitate the use of specialized winding spools for proper handling during production, transportation, storage, and use.

[0003] In actual winding operations, workers first need to fix one end of the steel strand to the drum. Then, a drive device rotates the drum, causing the steel strand to wind evenly along the drum's axis, ultimately completing the winding process. However, the initial fixing of the steel strand usually relies on grooves or through holes on the drum. Workers bend the end of the steel strand and embed it into the groove or pass it through the through hole to achieve fixation. However, with this fixing method, the steel strand is prone to shifting and loosening within the groove or through hole, resulting in poor fixation. Furthermore, when using the steel strand, workers need to detach the fixed end of the steel strand again, making the operation cumbersome. Utility Model Content

[0004] The purpose of this application is to provide a winding drum for winding steel strands, so as to solve the technical problems of poor initial fixation effect of steel strands and cumbersome unwinding operation in the prior art.

[0005] To achieve the above objectives, the technical solution adopted in this application is: to provide a winding drum for winding steel strand, comprising:

[0006] The outer wall of the cylinder body has multiple annular grooves arranged axially and spaced apart to accommodate steel strands, and the annular grooves are provided with wire passages that communicate with the inner wall of the cylinder body.

[0007] The support frame is fixedly installed inside the cylindrical body;

[0008] A pressure-applying mechanism is located inside the cylindrical body and connected to the support frame; the pressure-applying mechanism has a free end that moves from top to bottom;

[0009] A long strip pressure block is fixedly installed on the free end of the pressure applying mechanism and located above the wire passage; the length direction of the long strip pressure block is consistent with the axial direction of the cylinder body;

[0010] The steel strand passes through the wire passage and enters the cylinder body. The free end of the pressure mechanism drives the long strip pressure block to move downward to squeeze and fix the steel strand. The cylinder body is rotated to make the steel strand wind around the annular groove.

[0011] In one possible implementation, the cylindrical body is further provided with a mounting base located directly below the support frame. The pressure applying mechanism includes a linear actuator and a rotating block. The fixed end of the linear actuator is hinged to the support frame. One end of the rotating block is hinged to the mounting base, and the other end is hinged to the free end of the linear actuator. The long strip pressure block is fixedly installed on the rotating block.

[0012] In one possible implementation, the rotating block is a rectangular frame, and the elongated pressure block is located on the side of the rectangular frame away from the mounting base.

[0013] In one possible implementation, the rotating block, the mounting base, and the elongated pressing block are all hollow tubes.

[0014] In one possible implementation, there are multiple pressure-applying mechanisms arranged sequentially along the axial direction of the cylinder body; there are multiple long strip pressure blocks, each corresponding to one of the multiple pressure-applying mechanisms.

[0015] In one possible implementation, the wire passage corresponds to the lower side of the cylinder body.

[0016] In one possible implementation, the lower end of the elongated pressure block is provided with a protective pad for contacting the steel strand.

[0017] In one possible implementation, the winding drum for coiling the steel strand further includes:

[0018] The base is fixedly installed inside the cylinder and located below the pressure applying mechanism; the base has a cavity for the steel strand to pass through, and one end has a long opening that communicates with the cavity; the long opening corresponds to the wire passage; the upper end of the base has a clearance opening that communicates with the cavity, and the clearance opening corresponds to the long pressure block.

[0019] In one possible implementation, the base is further provided with a plurality of parallel spaced partitions, which are arranged close to the elongated opening; a wire-passing groove corresponding to the wire-passing channel is formed between two adjacent partitions.

[0020] In one possible implementation, the lower end face of the base is further provided with a reinforcing block corresponding to the clearance opening.

[0021] The beneficial effects of the winding drum for steel strand winding provided in this application are as follows: Compared with the prior art, the winding drum for steel strand winding in this application uses the drum body as the core storage component. The multiple axially spaced annular grooves on its outer wall provide a regular winding space for the steel strand, avoiding the problem of overlapping or gaps in the steel strands when storing them in traditional winding drums. The wire passage channel on the annular grooves, which connects to the inner wall of the drum body, constructs a channel for the steel strand to enter the internal fixing structure from the outside, providing a foundation for subsequent stable fixing. The support frame is fixed inside the drum body and mainly plays the role of bearing the pressure mechanism, ensuring that the pressure mechanism maintains a stable working state during the rotation of the drum body. As a power execution component, the pressure mechanism's free end, which can move from top to bottom, provides driving force for the fixing action. The long strip pressure block, as a component that directly acts on the steel strand, is designed with its length direction aligned with the axis of the drum body, which can form a complete fit with the wire passage channel, ensuring a uniform pressure effect on the steel strand. When the workers are winding the steel strand, they first pass the end of the steel strand through the wire passage on the annular groove into the inside of the drum body. Then, they activate the pressure mechanism connected to the support frame, causing its free end to drive the long strip pressure block to move from top to bottom until the long strip pressure block tightly presses the steel strand passing through the wire passage into the wire passage, thus completing the stable fixation of the steel strand's fixed end. Finally, the drive mechanism drives the drum body to rotate, and the steel strand will be evenly wound around the outer wall of the drum body along the trajectory of the annular groove, achieving orderly storage. When it is necessary to retrieve the steel strand, simply control the pressure mechanism to drive the long strip pressure block to return to its original position, releasing the pressure constraint on the steel strand. The workers then apply force to the other end of the steel strand to pull the entire steel strand out of the drum body.

[0022] In this way, by using the combined squeezing of the long strip pressure block and the wire passage, the fixed end of the steel strand is firmly limited, avoiding the problem of the steel strand easily shifting or loosening, ensuring the stability of the winding process, and allowing the steel strand to be neatly wound along the annular groove, improving the storage capacity and storage quality of the winding drum; moreover, the fixing and unlocking of the steel strand can be completed simply by the lifting action of the pressure mechanism, without the need for workers to painstakingly separate the steel strand end embedded in the groove or through hole, simplifying the operation process.

Therefore, they should not be construed as limitations on this application.

[0033] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0034] Please see Figures 1 to 5The present application will now describe the winding drum for coiling steel strand. A winding drum for coiling steel strand includes a drum body 10, a support frame 20, a pressing mechanism 30, and a long strip pressing block 40. The outer wall of the drum body 10 has multiple annular grooves 11 arranged axially at intervals to accommodate the steel strand, and each annular groove 11 has a wire passage connecting to the inner wall of the drum body 10. The support frame 20 is fixedly installed inside the drum body 10. The pressing mechanism 30 is located inside the drum body 10 and connected to the support frame 20. The pressing mechanism 30 has a free end that moves downwards. The long strip pressing block 40 is fixedly installed on the free end of the pressing mechanism 30 and is located above the wire passage. The length direction of the long strip pressing block 40 is aligned with the axial direction of the drum body 10. The steel strand passes through the wire passage into the drum body 10, and the free end of the pressing mechanism 30 drives the long strip pressing block 40 downwards to compress and fix the steel strand. Rotating the drum body 10 causes the steel strand to wind around the annular grooves 11.

[0035] Compared with the prior art, the winding drum for steel strand provided in this application has a core storage component, the drum body 10. Multiple axially spaced annular grooves 11 on its outer wall provide a regular winding space for the steel strand, avoiding the problem of overlapping or gaps in the steel strand when storing it in a traditional winding drum. The wire passage channel on the annular groove 11, which connects to the inner wall of the drum body 10, forms a channel for the steel strand to enter the internal fixing structure from the outside, providing a foundation for subsequent stable fixing. The support frame 20 is fixed inside the drum body 10 and mainly plays the role of bearing the pressure applying mechanism 30, ensuring that the pressure applying mechanism 30 maintains a stable working state during the rotation of the drum body 10. The pressure applying mechanism 30, as a power execution component, provides driving force for the fixing action through its free end that can move from top to bottom. The long strip pressure block 40, as a component that directly acts on the steel strand, is designed with its length direction aligned with the axis of the drum body 10, which can form a full fit with the wire passage channel, ensuring a uniform pressure effect on the steel strand. When the workers are winding the steel strand, they first pass the end of the steel strand through the wire passage on the annular groove 11 and insert it into the drum body 10. Then, they activate the pressure mechanism 30 connected to the support frame 20, which causes the free end of the pressure mechanism 30 to drive the long strip pressure block 40 to move from top to bottom until the long strip pressure block 40 tightly presses the steel strand passing through the wire passage into the wire passage, thus securing the fixed end of the steel strand. Finally, the drive mechanism 70 drives the drum body 10 to rotate, and the steel strand will be evenly wound around the outer wall of the drum body 10 along the trajectory of the annular groove 11, achieving orderly storage. When the steel strand needs to be retrieved, the workers only need to control the pressure mechanism 30 to drive the long strip pressure block 40 to return to its original position, releasing the pressure constraint on the steel strand. The workers can then apply force to the other end of the steel strand to pull the entire steel strand out of the drum body 10.

[0036] In this way, with the help of the long strip pressure block 40 and the wire passage, the fixed end of the steel strand is firmly limited, avoiding the problem of the steel strand easily moving or loosening, ensuring the stability of the winding process, and allowing the steel strand to be neatly wound along the annular groove 11, improving the storage capacity and storage quality of the winding drum; moreover, the fixing and unlocking of the steel strand can be completed by the lifting action of the pressure mechanism 30, without the need for workers to painstakingly separate the end of the steel strand embedded in the groove or through hole, simplifying the operation process.

[0037] In practical use, the other end of the steel strand is located at the upper end of the entire drum body 10. When using the steel strand, simply rotate the drum body 10 in the reverse direction to gradually remove the steel strand from the annular groove 11. A guide tube 60 is provided on one side of the drum body 10, corresponding to the wire passage. The steel strand passes through the guide tube 60 and enters the wire passage accurately and smoothly.

[0038] Please see Figures 1 to 3 As a specific embodiment of the winding drum for steel strand provided in this application, the drum body 10 is further provided with a mounting base 12 located directly below the support frame 20. The pressure mechanism 30 includes a linear actuator 31 and a rotating block 32. The fixed end of the linear actuator 31 is hinged to the support frame 20; one end of the rotating block 32 is hinged to the mounting base 12, and the other end is hinged to the free end of the linear actuator 31; the long strip pressure block 40 is fixedly installed on the rotating block 32. By adding a mounting base 12 inside the drum body 10, the pressure mechanism 30 is set as a hinged combination of the linear actuator 31 and the rotating block 32. The mounting base 12 provides bottom hinged support for the rotating block 32. The fixed end of the linear actuator 31 is hinged to the support frame 20, and the free end is hinged to the other end of the rotating block 32. The long strip pressure block 40 is fixedly installed on the rotating block 32, and the long strip pressure block 40 is stably raised and lowered by means of hinged transmission. During operation, after the steel strand passes through the wire passage, the linear actuator 31 is activated, and its free end extends and retracts to drive the rotating block 32 to rotate around the mounting base 12, which in turn drives the long strip pressure block 40 to press down and fix the steel strand. Then the rotating drum body 10 completes the winding. Before taking it out, the linear actuator 31 is reset, and the rotating block 32 drives the long strip pressure block 40 to lift up and unlock.

[0039] Please see Figure 2 and Figure 3 In one specific embodiment of the steel strand winding drum provided in this application, the rotating block 32 is a rectangular frame, and the long strip pressure block 40 is located on the side of the rectangular frame away from the mounting base 12. Setting the rotating block 32 as a rectangular frame is both lightweight and provides good structural stability. Placing the long strip pressure block 40 on the side away from the mounting base 12 allows for precise alignment with the wire passage. This method improves the accuracy of pressure application, makes the fixation more secure, and facilitates operation.

[0040] Please see Figures 1 to 5 As a specific embodiment of the winding drum for steel strand winding provided in this application, the rotating block 32, the mounting base 12 and the long strip pressure block 40 are all hollow tubes, which can reduce the overall weight of the winding drum and save materials while ensuring structural strength.

[0041] Please see Figure 1 and Figure 2 As a specific embodiment of the winding drum for steel strand winding provided in this application, there are multiple pressure applying mechanisms 30, which are arranged sequentially along the axial direction of the drum body 10; there are multiple long strip pressure blocks 40, which correspond one-to-one with the multiple pressure applying mechanisms 30, which can adapt to the winding requirements of multiple annular grooves 11 of the drum body and realize the simultaneous fixing of multiple sections of steel strand.

[0042] Please see Figure 1 , Figure 2 and Figure 4 As a specific embodiment of the winding drum for steel strand provided in this application, the wire passage corresponds to the lower side of the drum body 10, which not only matches the natural force direction during steel strand winding, but also achieves precise alignment with the long strip pressure block 40 inside the drum. During operation, the operator can pass the end of the steel strand through the wire passage into the interior from below the drum body, making the wire threading operation more convenient without weakening the upper structural strength of the drum body 10, thus balancing fixation stability, operational convenience, and structural reliability.

[0043] Please see Figure 2 and Figure 3 As a specific embodiment of the winding drum for steel strand provided in this application, the lower end of the long strip pressure block 40 is provided with a protective pad 41 for contacting the steel strand, which can prevent the long strip pressure block 40 from making hard contact with the steel strand. The pressure mechanism 30 drives the long strip pressure block 40 to press down, and the protective pad 41 adheres to the surface of the steel strand to achieve flexible compression and fixation. The protective pad 41 increases the friction to improve the fixation stability, and can also effectively protect the anti-corrosion coating on the surface of the steel strand, avoid scratches and wear, and extend its service life. At the same time, the flexible contact can be adapted to steel strands of different diameters, improving versatility. The protective pad 41 is preferably made of an elastic and wear-resistant material.

[0044] Please see Figures 2 to 5As a specific embodiment of the steel strand winding spool provided in this application, the steel strand winding spool also includes a base 50, which is fixedly installed inside the spool body 10 and located below the pressure applying mechanism 30. The base 50 has an internal receiving cavity 51 for the steel strand to pass through, and one end has a long opening communicating with the receiving cavity 51; the long opening corresponds to the wire passage. The upper end of the base 50 has a clearance opening 52 communicating with the receiving cavity 51, and the clearance opening 52 corresponds to the long pressure block 40. The receiving cavity 51 inside the base 50 provides dedicated storage space for the end of the steel strand, and the long opening at one end precisely corresponds to the wire passage, ensuring smooth passage of the steel strand. The clearance opening 52 at the upper end is aligned with the long pressure block 40, reserving space for the long pressure block 40 to apply pressure. Simultaneously, the fixed installation of the base 50 further enhances the overall structural stability of the winding spool. During operation, the operator sequentially passes the end of the steel strand through the wire guide channel and the elongated opening into the receiving cavity 51. The pressure mechanism 30 is then activated, driving the elongated pressure block 40 to move downwards through the clearance opening 52, where it engages with the inner wall of the receiving cavity 51 to achieve tight compression and fixation of the steel strand. The receiving cavity 51 provides dual restraint for the end of the steel strand, further resolving the problem of the steel strand shifting and loosening. The precise fit between the elongated opening and the clearance opening 52 improves operational smoothness. The base 50 both distributes the force and protects the end of the steel strand, significantly enhancing fixation stability and equipment durability, making it suitable for various engineering winding scenarios.

[0045] Please see Figures 2 to 5 As a specific embodiment of the winding drum for steel strand provided in this application, the base 50 is further provided with multiple parallel and spaced partitions 53, which are arranged close to the elongated opening. A wire-passing groove corresponding to the wire-passing channel is formed between two adjacent partitions 53, realizing the branching and limiting of the steel strand. The end of the steel strand passes through the wire-passing channel and the corresponding wire-passing groove in sequence and extends into the receiving cavity 51. The elongated pressure block 40 presses down through the clearance opening 52, cooperating with the inner wall of the wire-passing groove to compress and fix the steel strand. The wire-passing groove can prevent multiple steel strands from tangling in the base 50, improving the fixing accuracy and stability. At the same time, the partitions 53 enhance the structural strength of the base 50, adapting to the usage requirements of multiple pressure mechanisms 30.

[0046] Please see Figures 2 to 5 As a specific embodiment of the winding drum for steel strand provided in this application, the lower end face of the base 50 is also provided with a reinforcing block 54 corresponding to the clearance opening 52, which strengthens the structure of the base 50 at the clearance opening 52 and prevents the base 50 from deforming due to excessive local force during pressure application. The pressure application mechanism 30 drives the elongated pressure block 40 through the clearance opening 52, forming a corresponding compression with the reinforcing block 54 to achieve a stable fixation of the steel strand. The reinforcing block 54 not only ensures the structural strength and durability of the base 50, but also improves the stability of the elongated pressure block 40 during pressure application.

[0047] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
