Description

Technical Field

[0001] The utility model belongs to the technical field of hoisting cables, in particular to a vertical hoisting cable for urban construction. Background Art

[0002] Hoisting cables, also known as tower crane cables, are mainly power transmission and control cables, and are widely used in large tower cranes, cranes, stackers, reeling machines, outdoor elevators for construction, sewage treatment plants, and magnet grabs;

[0003] Due to the strength requirements of the cable, the overall hardness is relatively large and has high tensile resistance. However, despite the high hardness, the cross-section of the entire cable is still a solid structure, which reduces the bending toughness and is not conducive to storage, transportation, installation, maintenance and other work. It occupies a large space, and the cable is too hard and heavy, causing great damage to nearby objects, equipment, and personnel during use.

[0004] In order to solve the above problems, this application proposes a vertical hanging cable for urban construction. Utility Model Content

[0005] The utility model aims to provide a vertical hanging cable for urban construction, which solves the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0007] The utility model is a vertical hoisting cable for urban construction, comprising a cable core and a steel wire rope, and also comprising a bracket located at the center of the cable, wherein the cable core and the steel wire rope are both arranged in multiple pieces, and the multiple cable cores and the steel wire ropes are stably supported in the cable by the bracket, and a filling layer is formed on the outside of the bracket, an inner coating layer is formed on the outside of the filling layer, and a flame retardant strip is connected to the outside of the inner coating layer, and the flame retardant strips are arranged in multiple pieces distributed in a circle, and the multiple flame retardant strips are wrapped around the outside of the inner coating layer, and an outer coating layer is formed on the outside of the flame retardant strips.

[0008] Furthermore, the bracket is provided with a No. 1 groove and a No. 2 groove respectively, the cable core is attached to the outside of the bracket through the No. 1 groove, the steel wire rope is attached to the outside of the bracket through the No. 2 groove, and a plurality of the cable cores and steel wire ropes are evenly arranged on the outside of the bracket.

[0009] Furthermore, the flame retardant strip is in a wavy spiral shape outside the inner covering layer, and the end surfaces of two adjacent flame retardant strips are in contact with each other.

[0010] Furthermore, the flame retardant strip is bonded to the contact surface of the inner covering layer by glue.

[0011] Furthermore, a buffer groove is formed on the outside of the flame retardant strip, the outside of the buffer groove is an open structure, and the front of the opening is opposite to the inner side of the outer covering layer.

[0012] Furthermore, the buffer groove is opened on the flame retardant strip in a circumferential direction around the cable.

[0013] Furthermore, the buffer grooves on two adjacent flame retardant strips are distributed horizontally.

[0014] The utility model has the following beneficial effects:

[0015] The utility model provides a buffer groove on the outer surface of the flame retardant strip, and the buffer groove can form a certain amount of space inside the cable, and when the cable is bent, a certain deformation space can be provided, thereby increasing the bending degree of the cable. At the same time, since an outer coating layer is provided on the outside of the buffer groove, when the cable collides with equipment or personnel, the buffer groove provides an inward deformation space for the outer coating layer, thereby achieving a certain buffering effect and reducing the potential safety hazards caused to equipment or personnel.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] In the description of the present invention, it should be understood that terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0027] See also Figure 1-4 As shown, the utility model is a vertical lifting cable for urban construction, including a cable core 2 and a steel wire rope 3, and also includes a bracket 1 located in the center of the cable, the cable core 2 and the steel wire rope 3 are both arranged in multiple pieces, and the multiple cable cores 2 and the steel wire rope 3 are stably supported in the cable by the bracket 1, and a filling layer 4 is formed on the outside of the bracket 1, an inner coating layer 5 is formed on the outside of the filling layer 4, and a flame retardant strip 6 is connected to the outside of the inner coating layer 5, and the flame retardant strip 6 is arranged in multiple pieces distributed in a circle, and the multiple flame retardant strips 6 are wrapped around the outside of the inner coating layer 5, and an outer coating layer 7 is formed on the outside of the flame retardant strip 6.

[0028] Among them, the bracket 1 is respectively provided with a No. 1 groove 11 and a No. 2 groove 12, the cable core 2 is attached to the outside of the bracket 1 through the No. 1 groove 11, and the wire rope 3 is attached to the outside of the bracket 1 through the No. 2 groove 12. Multiple cable cores 2 and wire ropes 3 are evenly arranged on the outside of the bracket 1. In this embodiment, the bracket 1 stabilizes the positions of the multiple cable cores 2 to ensure the reliability of cable use. The bracket 1 stably limits the wire rope 3 to ensure the uniformity of the overall strength of the cable and the overall performance of the cable.

[0029] Among them, the flame retardant strip 6 is a wavy spiral outside the inner coating layer 5, and the end faces of two adjacent flame retardant strips 6 are fitted together. The wavy fitting in this embodiment can enhance the axial tensile strength, and the flame retardant strip 6 does not need to be wound into shape, which is convenient for forming in the cable.

[0030] The contact surface between the flame retardant strip 6 and the inner covering layer 5 is bonded by glue. In this embodiment, the glue is used to assist in positioning the flame retardant strip 6 outside the inner covering layer 5 , and the final one-piece molding is achieved through the outer covering layer 7 .

[0031] Among them, a buffer groove 61 is formed on the outside of the flame retardant strip 6, and the outside of the buffer groove 61 is an open structure, and the front of the opening is opposite to the inner side of the outer covering layer 7. In this embodiment, the outside of the buffer groove 61 is opened to ensure sufficient mobility. The buffer groove 61 can deform inward when squeezed, and can deform into the adjacent buffer groove 61 when stretched, which is more flexible. The opening at one end also facilitates the molding of the buffer groove 61.

[0032] Among them, the buffer groove 61 is opened on the flame retardant strip 6 around the circumferential direction of the cable. In this embodiment, the circumferential direction is exactly perpendicular to the axial direction of the cable. During the axial bending of the cable, the annular buffer groove 61 can provide deformation space and increase the bending angle.

[0033] Among them, the buffer grooves 61 on two adjacent flame retardant strips 6 are horizontally distributed. In this embodiment, the parallel distributed buffer grooves 61 form a complete buffer circle in the circumferential direction of the cable, which can adapt to the buffering when the cable is bent in any direction and provide sufficient deformation space.

[0034] It can be understood that the flame retardant strip 6 set first can provide deformation space during the bending process of the cable, and improve flexibility without affecting the reliability of the structure. The buffer groove 61 can also form a buffer deformation space when it collides with the outside to provide protection for the object. Secondly, the wavy spiral setting between the multiple flame retardant strips 6 can not only ensure the performance of the flame retardant layer, but also increase the axial tensile force to ensure the cable performance. Finally, the bracket 1 set can provide a stable support space for the cable core 2 and the steel wire rope 3 to ensure the direct structural stability of each other.

[0035] A specific application of this embodiment is: the cable core 2 is positioned by the No. 1 groove 11 on the bracket 1, and the steel wire rope 3 is positioned by the No. 2 groove 12. At this time, the multiple cable cores 2 and steel wire ropes 3 are evenly distributed, and a filling layer 4 is filled on the outside and an inner coating layer 5 is formed. Multiple flame retardant strips 6 are attached to the outside of the flame retardant strips 6 to form a flame retardant protective layer, and then an outer coating layer 7 is formed on the outermost part of the cable. The outer coating layer 7 connects the multiple flame retardant strips 6 into one piece in the cable.
