A kind of tunnel power cable support holding clamp comprises jig, plain cushion, spring pad and nut, it is characterized in that: described jig is half U type, described power cable support comprises curved support and cross-brace, curved support and cross-brace are equipped with U-shaped hole, curved support radian is consistent with tunnel radian, cross-brace in the horizontal direction, described half U type jig is connected and fixed by the U-shaped hole in the cross-brace of pad and nut and power cable, in cross-brace, the quantity in U-shaped hole is multiple, quantity according to power cable is determined, holding clamp carries out galvanizing by dipping process all in advance.
Description
Technical field
The utility model relates to a kind of holding clamp, particularly relates to a kind of tunnel power cable support holding clamp, and this holding clamp is applicable to the fixing of power cable under the similar tunnel environments such as subway and telecommunication cable erection.
Background technique
In usual subway tunnel, power cable construction adopts Steel Bracket to lay, and power cable on Steel Bracket more adopts U-shaped jig directly to be fixed by matching nut, and this means of fixation causes power cable surrounding to form a steel (iron) property closed-loop path.If form closed-loop path in power cable surrounding all can cause eddy current, these eddy current make cable core generate heat in a large number, waste a large amount of electric energy, reduce power cable efficiency, and in power cable system electric current more maelstrom is also larger, endanger also larger.Under serious conditions, power cable insulation layer is burnt out, cause system generation ground fault, and damage more serious to power cable fixed support.
Model utility content
The purpose of this utility model is exactly to overcome the defect existed in above-mentioned prior art and a kind of tunnel power cable support holding clamp effectively can avoiding eddy current loss provided.
To achieve these goals, the technical solution adopted in the utility model is: a kind of tunnel power cable support holding clamp comprises jig, plain cushion, spring pad and nut, it is characterized in that: described jig is half U type.
Described power cable support comprises curved support and cross-brace, and curved support and cross-brace are provided with U-shaped hole, and curved support radian is consistent with tunnel radian, and cross-brace in the horizontal direction.Half U type jig is connected and fixed by the U-shaped hole in the cross-brace of pad and nut and power cable.In cross-brace, the quantity in U-shaped hole is multiple, and the quantity according to power cable is determined.
Holding clamp carries out galvanizing by dipping process all in advance.
Compared with prior art, the utility model has the advantages that: this tunnel power cable support holding clamp makes cable surrounding can not form steel (iron) property closed-loop path, stop cable vortex phenomenon from means of fixation to occur, compared with U-shaped holding clamp, effectively stop cable vortex phenomenon to occur, improve cable working efficiency, reduce Steel Bracket loss.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing a kind of tunnel power cable support holding clamp.
Fig. 2 is the structural representation of a kind of tunnel of the present utility model power cable support holding clamp.
Fig. 3 is the schematic diagram in the U-shaped hole in the cross-brace of power cable support.
In figure, sequence number illustrates: 1-cross-brace, 2-jig, 21-U type jig, 3-plain cushion, 4-spring pad, 5-nut, 6-curved support, 7-U nibs.
Embodiment
Be described in detail below in conjunction with Fig. 1-3 pairs of the technical solution of the utility model, but content of the present utility model is not limited thereto.
As shown in Figure 2, a kind of tunnel power cable support holding clamp comprises jig 2, plain cushion 3, spring pad 4 and nut 5, and described jig is half U type, compared with the U-shaped jig 21 in Fig. 1, effectively can stop cable vortex phenomenon to occur, improve cable working efficiency, reduce Steel Bracket loss.Power cable support comprises curved support 6 and cross-brace 1, and curved support 6 and cross-brace 1 are provided with U-shaped hole 7, and curved support 6 radian is consistent with tunnel radian, and cross-brace 1 in the horizontal direction.Half U type jig 2 is connected and fixed with the U-shaped hole 7 in the cross-brace 1 of power cable by pad and nut 5.
The foregoing is only mode of execution of the present utility model citing, and be not used to limit scope of authority of the present utility model, all interest fields of containing with the application's the scope of the claims and implementer, all do not depart from protection domain of the present utility model.
