Description

Technical Field

[0001] The present invention relates to the technical field of electric power line hanging tools, in particular to a cable hanging device. Background Art

[0002] When laying cables, due to the large span between cable support frames, the cables sag or even break under the action of tension and self-weight. Traditionally, a steel strand is laid in the air and the cables are hung on the strand by winding metal wire or hooking.

[0003] Traditional hooks consist of a length of wire bent into a V-shape in the middle and hooked at both ends. The V-shaped inflection point allows the cable to pass through. To operate a traditional hook, the hook at one end of the wire must first be hooked onto the steel strand. The hook must then be looped around the cable and the hook at the other end reattached to the strand. This makes traditional hooks prone to falling off the strand during operation. Furthermore, because the operator is suspended in mid-air, the detached hook often falls to the ground, making it difficult to retrieve. Furthermore, auxiliary tools are sometimes required, which can seriously affect the efficiency of cable hanging operations and even endanger the operator's personal safety. To prevent the hook from swinging longitudinally in the wind, some construction workers modify the V-shaped hook into a W-shape. However, this structure requires first attaching the hook to the cable, then bending the two hooks to deform the wire and place the cable into the two V-shaped corners of the W-shaped hook. Finally, the two hooks are repositioned and hooked onto the strand, making aerial work extremely inconvenient. Since the bending amplitudes of the two hooks are inconsistent and the position of the metal wire hooks on the steel strands is not standard, it is easy for the hooks to be not hooked firmly, and the metal wire of the hooks is prone to fatigue damage during the deformation process, which can easily cause accidents.

[0004] In addition, since traditional hooks are only connected to the steel wire ropes through metal wire hooks, the cables swing under the influence of factors such as wind, and the swinging often causes the hooks to fall off the steel wire ropes; in addition, when the wind is strong, the traditional hooks will be subjected to large shear forces, causing the hooks to break.

[0005] Furthermore, the existing hook has the defect that the contact surface with the cable is small and the insulation layer of the cable is easily damaged. Summary of the Invention

[0006] In view of this, it is necessary to propose a cable hanging device to address the above problems. The device can be firmly hung on the steel strand and is not easy to fall off. It can prevent the cable from swinging longitudinally, making power construction operations safer, more convenient and more standardized. It also improves its own service life and structural strength, greatly reducing the risk of cable falling and damage.

[0007] To achieve the above object, the present invention adopts the following technical solutions:

[0008] A cable hanging device for supporting cables and hanging them on steel strands, the cable hanging device comprising a wire hanging fastener and at least two cable supporting members; the wire hanging fastener comprising a fastening ridge and extended wings extending downward along both sides of the fastening ridge, the fastening ridge and the extended wings forming a wire fastening groove, the wire fastening groove being used for fastening and hanging steel strands; the cable supporting member comprising a connecting arm and a cable supporting portion provided at one end of the connecting arm, the other end of each connecting arm being hinged to the wire hanging fastener, the cable supporting portion being used for supporting cables; at least two cable supporting members being arranged opposite to each other.

[0009] Furthermore, there are two connecting arms, one of which is a first cable supporting arm and the other is a second cable supporting arm; the other end of the first cable supporting arm and the other end of the second cable supporting arm are both hinged to the wire hanging fastener.

[0010] Furthermore, there are four connecting arms, two of which are arranged opposite to each other and are first supporting cable arms, and the other two connecting arms are arranged opposite to each other and are second supporting cable arms; the other ends of the two first supporting cable arms are hinged to one end / side of the hanging wire fastener, and the other end of each second supporting cable arm is hinged to the other end / side of the hanging wire fastener.

[0011] Furthermore, the buckling ridge is provided with a through axial hole along the length direction; the cable hanging device also includes a hinged limit shaft inserted into the axial hole, and the other end of the first supporting cable arm and the other end of the second supporting cable arm are both provided with a hinge hole through which the hinged limit shaft is inserted; the first supporting cable arm and the hanging wire buckle are hinged through the hinged limit shaft passing through the axial hole and the hinge hole; the second supporting cable arm and the hanging wire buckle are hinged through the hinged limit shaft passing through the axial hole and the hinge hole.

[0012] Furthermore, the hinged limiting shaft is a bolt; the cable hanging device also includes a nut screwed to one end of the bolt.

[0013] Furthermore, the cable supporting portion of at least one of the cable supporting members is a plate-shaped cable supporting plate.

[0014] Furthermore, the cross section of the cable supporting plate is arc-shaped, and the inner arc surface thereof is the cable supporting surface.

[0015] Furthermore, the cable support plate is provided with a protective strip protruding from a side portion opposite to the connecting arm; the protective strip is used to prevent the cable from falling off longitudinally from the cable support plate.

[0016] Furthermore, the cable hanging device further comprises a plurality of tensioning members installed on the other end portion of at least one of the connecting arms; the tensioning members are used to tension the cable supporting member.

[0017] Furthermore, the wire hanging fastener and the cable supporting member are both composite structures, and the composite structure includes a metal frame and an anti-wear layer at least partially covering the metal frame.

[0018] The beneficial effects of the present invention are:

[0019] 1) The present invention limits the longitudinal sides of the steel strand and hangs the steel strand tightly through the wire fastening groove of the wire hanging fastener. The wire hanging fastener forms a firm and non-easy force application area on the steel strand; the long strip of wire hanging fastener can be placed on the steel strand in a horizontal and balanced manner.

[0020] 2) In the present invention, the force exerted by one side of the steel strand on one extension wing and the force exerted by the cable swinging from one longitudinal side cancel each other out, and the force exerted by the other side of the steel strand on the other extension wing and the force exerted by the cable swinging from the other longitudinal side cancel each other out, thereby making it difficult for the cable to swing longitudinally;

[0021] 3) The present invention hinges the wire hanging fasteners to the cable support members, eliminating the need for reinforcement tools (such as pliers). The wire hanging fasteners can be directly fastened to the cables, and the cable support members can be manually brought closer to the cables to support them, thereby securely hanging the cables under the steel strands. This makes high-altitude power construction work safer and more convenient, and installation can be performed in a few simple manual steps, making power construction work more standardized. The present invention uses a tensioning member to achieve elastic resetting of the cable support members, further improving the convenience of construction work.

[0022] 4) The present invention avoids the traditional installation method of hanging cables by wrapping metal wires and using tools to compress the hooks, thereby improving its service life and structural strength;

[0023] 5) The present invention supports the cables through the cable supporting portion, which can better protect the cables while supporting them. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Example 1

[0035] like Figure 1 、 Figure 3As shown, a cable hanging device is used to support a cable 2 and hang it on a steel strand 1.

The cross section of the cable trough is an inverted V-shape or an inverted U-shape; the inverted V-shaped cable trough uses the weight of the cable hanging device and the cable 2 to clamp the steel strand 1, thereby further preventing the cable hanging fastener 3 from rotating around the steel strand 1 as the cable 2 swings longitudinally; the inverted U-shaped cable trough uses the weight of the cable hanging device and the cable 2 to increase the friction between the cable hanging fastener 3 and the steel strand 1, thereby further preventing the cable hanging fastener 3 from rotating around the steel strand 1 as the cable 2 swings longitudinally; the connecting arm is arc-shaped, with the inner arc surface facing the cable 2, thereby increasing the supporting space of the cable hanging device for the cable 2;

[0036] There are preferably two connecting arms, one of which is a first cable supporting arm 41, and the other connecting arm is a second cable supporting arm 42; the other end of the first cable supporting arm 41 and the other end of the second cable supporting arm 42 are both hinged to the wire hanging fastener 3; the first cable supporting arm 41 and the second cable supporting arm 42 are respectively located on both sides of the supporting space of the cable 2.

[0041] Furthermore, if Figure 1 、 Figure 3 As shown, the cross section of the supporting plate 412 is arc-shaped, and its inner arc surface is the cable supporting surface, which can make the supporting plate 412 fit better with the outer surface of the cable, further increase the cable supporting surface, and better protect the cable.

[0042] Furthermore, if Figure 1 、 Figure 3 As shown, the wire hanging fastener 3 and the cable support 4 are both composite structures, and the composite structure includes a metal skeleton and an anti-wear layer that at least partially covers the metal skeleton.

Preferably, the metal skeleton is placed in a mold and injection molded with plastic. The composite structure can ensure the structural strength of the cable hanging device while preventing the cable 2 from being worn or scratched and the steel from rusting. The structural strength of the component is improved by the metal skeleton wrapped in the anti-wear layer, and the cable is prevented from being worn by the anti-wear layer, while also preventing the metal skeleton from rusting and being damaged.

[0047] Example 2

[0048] like Figure 2 As shown, a cable hanging device is used to support a cable 2 and hang it on a steel strand 1. The cable hanging device includes a hanging fastener 3 and at least two cable supporting members 4; the hanging fastener 3 includes a fastening ridge and extended wings extending downward along both sides of the fastening ridge, the fastening ridge and the extended wings forming a cable fastening groove, and the cable fastening groove is used to fasten and hang the steel strand; the cable supporting member 4 includes a connecting arm and a cable supporting portion provided at one end of the connecting arm, the other end of each connecting arm is hinged to the hanging fastener 3, and the cable supporting portion is used to support the cable 2; at least two cable supporting members 4 are arranged opposite to each other;

[0050] Working principle of the present invention:

[0051] The present invention uses the wire-hanging fastener's wire groove to hang on the steel strand in a balanced and stable manner, and reduces the cable's swing amplitude through the clamping effect of the wire groove or the friction effect on the steel strand; the extended wing prevents the wire-hanging fastener from falling off the steel strand and further reduces the cable's swing amplitude; the connecting arms and the cable supporting parts of each cable support member form an enclosed space for the cable hanging device when viewed from the side (refer to FIG. Figure 2 ), preventing cables from falling off longitudinally. The hinged connection between the cable hanging clips and cable supports allows multiple cable supports to be brought together and supported. The curved cross-section of the cable support plates, combined with the protective strips, prevents cables from falling off. To use the cable hanging device, simply attach the cable clip to the steel strand, then move the cable supports toward the cable, and finally place the cables on the cable supports for secure cable hanging.

[0052] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
