[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0022] Example

[0023] Reference Figures 1 to 3 As shown, the utility model provides a flat steel wire starting device for a flat steel wire winding machine, which is used for starting the flat steel wire of a tensile layer flat steel winding machine. The flat steel wire starting device includes a clamping ring 1, and the flat steel wire is fixed to the clamping ring 1 by a first fastener. Compared with manually arranging the flat steel wire, the flat steel wire starting device of the utility model can not only improve the arrangement accuracy and uniformity, but also realize rapid fixation and rapid starting, thereby improving processing efficiency.

[0024] Specifically, in an embodiment of the present invention, the pipe body to be armored and wrapped is set as a marine oil hose, and the pipe body itself is formed by winding steel strips or special-shaped steel. The traction pipe 2 is configured to be coaxially arranged with the pipe body to be wrapped, and one end of the pipe body can be detachably connected along the axial direction. The traction pipe 2 provides fixed support for the clamping ring 1.

[0025] Specifically, refer to Figure 3 As shown, the clamping ring 1 is arranged around the traction tube 2 and is fixed tightly against the outer circumference of the traction tube 2. In a preferred embodiment of the present invention, the clamping ring 1 is arranged as a split structure for ease of assembly. The clamping ring 1 includes at least two groups of clamping ring monomers 3. The clamping ring monomers 3 are arranged in the circumferential direction of the cross section of the traction tube 2. The clamping ring monomers 3 are connected end to end to form a circular ring structure. The clamping ring monomers 3 are used to tightly adhere to the inner edge of the traction tube 2 and are all arranged in the shape of a circular arc. The split and detachable clamping ring arrangement enables the flat steel starting device described in the present invention to adapt to traction tubes 2 of different sizes and shapes, and has higher flexibility.

[0026] Furthermore, the snap ring unit 3 also has a connecting portion 6, which is located at both end points of the circular arc of the snap ring unit 3 and extends outward along the radial direction of the snap ring 1, located on the side of the snap ring 1 facing away from the traction tube 2; the connecting portions 6 of adjacent snap ring units 3 are configured to be removably connected. Preferably, the connecting portions 6 of adjacent snap ring units 3 have surfaces that can abut against each other, and are provided with connecting holes 7 extending perpendicularly to the abutting surfaces. A second fastener is inserted into the connecting hole 7 to connect and secure the adjacent snap ring units 3. Preferably, the second fastener is configured as a screw, which is easy to disassemble and quickly tighten.

[0027] Furthermore, when the number of the snap ring monomers 3 is small, the number of the corresponding connecting parts 6 is small, and the fastening effect between the snap ring 1 and the traction pipe 2 is poor, and it is easy to deform or be desoldered during winding after starting; when the number of the snap ring monomers 3 is large, the number of the corresponding connecting parts 6 is large. On the one hand, the assembly is time-consuming and laborious and relatively cumbersome. On the other hand, too many connecting parts 6 affect the fixing position of the flat steel wire, restricting the winding and arrangement effects of the flat steel. In a preferred embodiment of the present utility model, three groups of the snap ring monomers 3 are provided. Preferably, the structures of the three groups of the snap ring monomers 3 are the same, and the central angles corresponding to the arcs of the inner edges of the three groups of the snap ring monomers 3 are all 120°; so that the force and the application force of each group of the snap ring monomers 3 are the same in magnitude and direction, avoiding the processing error during winding caused by the uneven fastening effect between each area of the snap ring 1 and the traction pipe 2.

[0028] Specifically, referring to Figure 1 as shown, a fixing hole 5 of the mounting hole 4 is further provided on the snap ring 1; the mounting hole 4 is used for threading a flat steel wire, the fixing hole 5 communicates with the mounting hole 4, and a first fastener is threaded in the fixing hole 5 to fix the flat steel wire in the fixing hole 5.

[0029] Furthermore, the mounting hole 4 is set as a cylindrical hole, and the cross-section of the mounting hole 4 is set as a circle, which is convenient for the flat steel wire to pass through; at the same time, the flat steel wire can also enter the inside of the mounting hole 4 from different angles. Compared with the mounting hole 4 with a square cross-section or a special-shaped cross-section, the cylindrical hole is convenient for processing and will not damage the outer layer of the flat steel wire, with less friction. The mounting hole 4 is arranged in a through manner along the axial direction of the traction pipe 2, and can adapt to various starting angles of the flat steel wire to avoid its bending damage.

[0030] Subsequently, the mounting holes 4 are arranged equidistantly in the circumferential direction of the snap ring 1; the flat steel wire can be threaded and installed at a suitable position of the mounting hole on the snap ring 1 according to the winding requirements; in an embodiment of the present utility model, the snap ring monomer 3 has 48 groups of the mounting holes 4, and each group of the snap ring monomers 3 has 16 groups of the mounting holes 4.

[0031] Furthermore, referring to Figure 1 and Figure 2 as shown, the fixing hole 5 is arranged in a through manner along the radial direction of the snap ring 1, and at least two groups of the fixing holes 5 are communicated with one group of the mounting holes 4, and the fixing holes 5 communicating with one group of the mounting holes 4 are arranged along the axial direction. It should be noted that the inner diameter of the snap ring 1, the aperture of the mounting hole 4, and the distance between two adjacent mounting holes 4 can be determined according to the actual winding and flat steel arrangement requirements, and are not limited thereto; in addition, the number and arrangement mode of the fixing holes 5 can also be determined according to the actual requirements of fixing the flat steel, and are not limited thereto.

[0032] The working principle of a flat wire starting device for a flat wire winding machine according to the present utility model is as follows:

[0033] The traction pipe 2 is connected to the pipe body to be armored and wound. Subsequently, the split ring monomers 3 are spliced, and the split ring 1 is fastened by passing a second fastener through the connection hole 7, so that the split ring 1 is fixed on the outer periphery of the traction pipe 2. According to the winding requirements and the specific model dimensions of the flat steel, the amount of flat steel used and the arrangement order are determined. One end of the flat wire is passed through the mounting hole 4 of the split ring 1 and locked by a first fastener, and the first fastener can be set as a screw; the other end of the flat wire is fixed to the flat steel winding machine of the tensile layer. After being tightened, the flat wire is straightened and has a certain preset angle with the axial direction of the pipe body, and the preset angle is related to the pre-twisting effect.

[0034] Start the flat steel winding machine of the tensile layer. After it rotates, the tightened flat steel is evenly wound on the pipe body of the marine hose. After winding a certain number of turns, the evenly wound flat wire is fixed by spot welding at the connection between the traction pipe 2 and the armored pipe body. Compared with the existing welding and fixing method for winding, the reliability is higher.

[0035] After welding is completed, the split ring 1 is removed, and the excess flat steel is cut off at the connection between the traction pipe 2 and the marine pipe body to complete the starting of the flat steel.

[0036] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present utility model.
