Description
Technical field
The utility model relates to transmission of electricity utensil, particularly a kind of telescoping cable support of simple to operate, use safety.
Background technology
We know, tunnel is the engineering works be embedded in stratum, it is a kind of form of human use's underground space, particularly traffic tunnel development in recent years speed is swift and violent, the conveying of electric power is an important engineering of traffic tunnel, power transmission line is generally adopt support to be fixed on tunnel-side wall, support is by erecting support and at least three lateral frames form, lateral frame interval vertical is welded on perpendicular support, perpendicular support expansion bolt is fixed on tunnel-side wall, power transmission cable is placed on lateral frame, when running into tunnel cross, during corner, because perpendicular support cannot be fixed on tunnel-side wall, power transmission cable is in vacant state, cable is easy to sustain damage, produce multiple dangerous phenomenon.
Summary of the invention
The purpose of this utility model solves above-mentioned the deficiencies in the prior art, provides a kind of compact conformation, the telescoping cable support that easy for installation, attached cable is effective.
The utility model solves the technical scheme that its technical problem adopts.
A kind of telescoping cable support, comprise the support be made up of perpendicular support and at least three lateral frames, lateral frame interval is also vertically welded on perpendicular support, it is characterized in that perpendicular pedestal upper end is provided with bearing seat type combination, perpendicular pedestal lower end is provided with base, axle sleeve is connected with combination through bearing group, screw rod upper end is provided with footstock, insert in axle sleeve by lower end after screw rod is connected with nut body, nut body lower end is provided with the annular boss matched with axle sleeve, ratchet housing is provided with outside nut body, nut body top layer is provided with the gear teeth, housing, nut body and the positive and negative mechanism of ratchet be arranged on housing, ratchet, rocking handle forms reversible ratchet mechanism, screw rod is provided with clamp nut, clamp nut leans in combination lower surface.
Axle sleeve described in the utility model is connected with combination with deep groove ball bearing through thrust bearing, to improve the pressure that it bears screw rod.
When the utility model uses, perpendicular support put into tunnel cable laying correct position and make perpendicular support be vertical configuration, the positive and negative button of ratchet is regulated to pull to left side and pull handle again, nut body is driven by ratchet, making screw rod increase makes screw rod footstock lean on tunnel roof, thrust bearing in the combined body of axial force that screw rod produces born, lateral frame being fixed by bolts to cable erects on support again, then by cable support on lateral frame, by the positive and negative button mechanism of ratchet and pull handle, can will screw rod move fixing or move down removal bracket, support on the ground by base under perpendicular support, on by screw top seat supports on tunnel roof, continue to wave handle and make that screw rod is micro-to be moved, perpendicular support will produce larger pressure and position firmly, there is compact conformation, easy for installation, use safety, the advantage such as reusable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with Fig. 1, the utility model is described in further detail:
As shown in the figure, a kind of telescoping cable support, comprise the support be made up of perpendicular support 1 and at least three lateral frames 2, lateral frame 2 interval is also vertically welded on perpendicular support 1, above-mentioned same as the prior art, this does not repeat, of the present utility modelly be characterised in that perpendicular support 1 upper end is provided with bearing seat type combination 3, perpendicular support 1 lower end is provided with base, axle sleeve 4 is connected with combination 3 through bearing group, , the bearing inner wall interference fit of axle sleeve 4 in bearing group, screw rod 5 upper end is provided with footstock, insert in axle sleeve 4 by lower end after screw rod 5 is connected with nut body 6, nut body 6 lower end is provided with the annular boss matched with axle sleeve 4, the pressure that screw shaped thing bears is through nut body 6, axle sleeve 4, bearing group and combination 3 pass to perpendicular support 1, locate firmly under the footstock bidirection press effect of the base of perpendicular support 1 through its lower end and screw rod 5 upper end, ratchet housing 7 is provided with outside nut body 6, nut body 6 top layer is provided with the gear teeth, housing 7, nut body 6 and the positive and negative mechanism 8 of ratchet be arranged on housing, ratchet, rocking handle 9 forms reversible ratchet mechanism, nut body 6, ratchet housing 7, nut body 6 top layer is provided with the gear teeth, the positive and negative mechanism 8 of ratchet, the structure of ratchet and rocking handle 9 and the interconnected relationship between them same as the prior art, this does not repeat, screw rod 5 is provided with clamp nut 12, clamp nut 12 leans in combination 3 lower surface in addition, axle sleeve described in the utility model is connected with combination with deep groove ball bearing 11 through thrust bearing 10, to improve the pressure that it bears screw rod 5.
When the utility model uses, perpendicular support put into tunnel cable laying correct position and make perpendicular support be vertical configuration, the positive and negative button of ratchet is regulated to pull to left side and pull handle again, nut body is driven by ratchet, making screw rod increase makes screw rod footstock lean on tunnel roof, thrust bearing in the combined body of axial force that screw rod produces born, lateral frame being fixed by bolts to cable erects on support again, then by cable support on lateral frame, by the positive and negative button mechanism of ratchet and pull handle, can will screw rod move fixing or move down removal bracket, support on the ground by base under perpendicular support, on by screw top seat supports on tunnel roof, continue to wave handle and make that screw rod is micro-to be moved, perpendicular support will produce larger pressure and position firmly, there is compact conformation, easy for installation, use safety, the advantage such as reusable.
