Description

Technical Field

[0001] The utility model belongs to the technical field of cables, in particular to a special reel tensile-resistant cable. Background Art

[0002] Special reel cables are high-quality cables that provide power output for large mobile equipment. They are usually installed on large mechanical equipment such as cranes, port machinery, and gantry cranes. They are suitable for outdoor environments such as port terminals and mines, as well as indoor environments such as power plants and steel mills. They have the characteristics of tensile resistance, wear resistance, drag resistance, UV resistance, and cold resistance.

[0003] The special tensile-resistant cable for port machinery drums disclosed in the Chinese authorized patent application publication number CN220306011U solves the problems of ordinary port machinery drum cables having poor tensile properties, being easily torn and damaged, and having a short service life.

[0004] Although the above-mentioned cables solve the problem of insufficient tensile strength by using built-in steel wire ropes, in actual applications, the steel wire ropes are installed using cotton ropes as tensile fillers, which undoubtedly greatly reduces the installation stability of the steel wire ropes. When used in large lifting equipment, the steel wire ropes are easily misaligned, causing damage to the cable core and shortening its service life, which is not conducive to the use of lifting equipment for heavy cargoes.

[0005] In order to solve the above problems, this application proposes a special tensile-resistant cable with a reel. Utility Model Content

[0006] The purpose of the utility model is to provide a special tensile-resistant cable on a drum, which solves the problem of easy loosening and dislocation of the steel wire rope proposed in the above background technology.

[0007] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0008] The utility model is a special tensile-resistant cable for a reel, comprising: a cable core and a filling layer and a coating layer on its outside; a limit frame, located in the center area of ​​an adjacent cable core, wherein the limit frame is spirally installed with a steel wire rope through a groove opened on the outside, so as to increase the contact area between the steel wire rope and the adjacent components and form a resistance to prevent loosening during use; a partition plate, which is two pieces installed opposite to each other and is used to cover the limit frame and the cable core, so that the cable forms a segmented structure, which is used to block stress and prevent the spread of tearing damage.

[0009] Furthermore, after the steel wire rope is installed, the limiting frame is extruded together with the cable core to form a filling layer.

[0010] Furthermore, a clamping groove is provided on the outer side of the limiting frame to form an elastically deformable clamping pad for clamping the steel wire rope for easy assembly and production.

[0011] Furthermore, a side groove is provided on the inner side of the partition for connecting the cable core and sleeved inside, and extension pads are provided on both sides of the partition for increasing the contact area with the wire rope.

[0012] Furthermore, the partition is divided into two pieces, a front piece and a back piece. A protruding plug is provided on one side of the front piece, which is docked with the inside of the positioning groove on the side opposite to the back piece.

[0013] Furthermore, protruding extension grooves are provided at the upper and lower ends of the positioning groove, and both ends are inclined surface structures.

[0014] Furthermore, protruding pads are provided at the upper and lower ends of the plugging block, which automatically dock with the extension grooves to fix the adjacent partitions after the plugging block is inserted into the positioning groove.

[0015] The utility model has the following beneficial effects:

[0016] The utility model cooperates with the limit frame and the wire rope so that the outer side thereof is extruded together with the filling layer in a spiral structure, thereby greatly increasing the contact area between the wire rope and the outer filling material, and also forming lateral resistance to increase its stability, effectively preventing the wire rope from being misaligned during use, so that the cable can lift heavier goods, improving the performance and further enhancing the safety of use;

[0017] The utility model can clamp the steel wire rope and the cable core in sections by adding partitions, so that the overall structure of the coating layer protects the cable core in sections. After this arrangement, it can not only block the transmission of internal stress, but also prevent the occurrence and large-scale spread of tearing damage, so as to limit the damage of the cable to a certain area for easy maintenance and use.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0029] In the description of the utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery" and the like indicate the orientation or positional relationship, which are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the indicated components or elements must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.

[0030] Please refer to Figure 1-6 The utility model discloses a kind of reel tensile special cables, comprising: cable core 1 and the filling layer 2 and cladding layer 3 outside it.

[0031] Limiting frame 4 is located in the center area of adjacent cable core 1, limiting frame 4 is installed steel wire rope 5 by clamping groove 7 being opened in outer side spirally, for increasing the contact area of steel wire rope 5 and adjacent component and forming resistance, to prevent loosening during use;

[0032] Baffle 6 is installed in two pieces oppositely, for covering limiting frame 4 and cable core 1, so that cable forms segmented structure, for blocking stress while preventing the spread of tearing damage;

[0033] This embodiment provides a special reel cable that can prevent the built-in steel wire mechanism from loosening and dislocating. The spiral installation structure is used to increase the contact area between the steel wire rope 5 and the filling layer 2, and a recessed docking structure is formed to increase resistance, thereby enhancing the tensile performance of the cable. At the same time, it can also prevent the steel wire rope 5 from loosening and dislocating when lifting heavier goods. In addition, the cable can be formed into a segmented structure through the partition 6, which can separate the internal stress of the cable while limiting the scope of external damage such as tearing, so as to prevent large-scale damage to the cable, delay damage, and facilitate subsequent maintenance and use.

[0034] Among them, after the steel wire rope 5 is installed, the limit frame 4 is extruded together with the cable core 1 to form a filling layer 2, so that the outer gaps of the steel wire rope 5 are tightly filled, increasing the contact area while ensuring the stability of the connection.

[0035] Among them, a slot 7 is opened on the outer side of the limit frame 4 to form an elastically deformable clamping pad 8, through which the wire rope 5 can be directly inserted into the inside of the slot 7, and the clamping pad 8 forms a limit to prevent it from falling off, which is convenient for assembly and production use.

[0036] A side groove 10 is provided on the inner side of the partition 6 for docking the cable core 1 to wrap it inside, and extension pads 11 are provided on both sides of the partition 6 for increasing the contact area with the steel wire rope 5 .

[0037] Among them, the partition 6 is divided into two pieces, front and back. A protruding plug 9 is provided on one side of the front piece, which docks with the inside of the positioning groove 12 on the opposite side of the back piece. During installation, the inner side surfaces of the front piece and the back piece are directly aligned and can be installed on the outside of the limit frame 4 and the cable core 1 to form a covering.

[0038] Among them, protruding extension grooves 13 are opened at the upper and lower ends of the positioning groove 12, and the two ends are inclined surface structures. Protruding pads 14 are provided at the upper and lower ends of the plug block 9. After the plug block 9 is inserted into the positioning groove 12, it automatically docks with the extension groove 13 to fix the adjacent partition 6.

[0039] It can be understood that the utility model can effectively prevent the built-in steel wire structure of the cable from slipping, improve the tensile performance and adapt to long-term cargo lifting operations. At the same time, it can prevent the spread of large-scale tearing of the cable outside and limit it to a certain area. It can also slow down the damage rate of the cable, facilitate maintenance and use after cargo lifting, and improve the safety of the cable when in use.

[0040] A specific application of the operating process of this embodiment is: when producing cables, the steel wire rope 5 is first clamped inside the card slot 7 by the elastic characteristics of the clamping pad 8, and then the spacing limit frame 4 and the cable core 1 are extruded together to form a filling layer 2, thereby greatly increasing the contact area between the steel wire rope 5 and the adjacent structure, and increasing the resistance through the spiral structure to ensure the stability of the installation; during the extrusion operation, the partition 6 is segmentedly sleeved on the outside of the limiting frame 4 and the cable core 1, so that the partition 6 is segmentedly installed inside the filling layer 2, thereby forming a barrier to the stress inside the cable to prevent large-scale spread when damage such as tearing occurs, and is used to limit the damage to a certain area for easy maintenance and processing. At the same time, it can also increase the tensile performance of the limiting frame 4 and the cable core 1 in each section, thereby improving the practicality of the cable.
