Abstract

The utility model discloses a wire lifting device which comprises a base, a lifting frame and a wire fixing clip. The base is a groove with an opening facing downwards; a side wall of the base is provided with a fastening screw rod; the top end of the screw rod is provided with a push plate; the base is arranged in the middle of the lifting frame; two ends of the lifting frame are provided a lifting device; the lifting device is composed of a spool; the lower end of the lifting device is provided with the wire fixing clip; the wire fixing clip is composed of a clip and a wire fixing device; the wire fixing device includes two arc-shaped sliding blocks; and the sliding blocks through a hard spring are respectively arranged in the middle of two clamping mouths of the clip. The wire lifting device is simple in structure; one person can quickly lift the wire to the tower top without the wire damaged; the stringing efficiency is greatly improved; and the wire lifting device is suitable for popularization.

Description

A kind of wire lifting device

Technical field

The utility model belongs to circuit on power system erection technique field, is specifically related to a kind of wire lifting device.

Background technology

Along with China's economic fast development, supply of electric power is relatively nervous, and for meeting the needs of national economy and social development, nation needs is accelerated the process that electric power system is built.In the construction of line process of electric power system, especially in the time that long distance is set up, usually need the middle part of cable to lift fixing, avoid the excessive damage that causes cable of span, safety and the problem such as attractive in appearance.But, the lifting and the fixing mode of tying up easily that conventionally adopts of existing cable, the method exists and bundlees that complex procedures, inefficiency, fastness are poor, the easy problem such as come off, and in lifting process, also has certain potential safety hazard.In addition, at power line maintenance, particularly power transmission tower or line bar in the wild, in the time of Construction and Maintenance, be by lifting wire to power transmission tower or line masthead end, now widely used method is to adopt suspension hook to carry the Line tool, and suspension hook on the one hand can be in various degree in the time promoting wearing and tearing wire, very easily cause on the other hand coming off of wire, make lifting wire very inconvenient, also make setting up or the time-consuming effort again of maintenance process of whole circuit.

Utility model content

Given this, the purpose of this utility model is to provide one not only to promote conveniently, can also prevent the wire lifting device of wire wearing and tearing.

A kind of wire lifting device, comprise base, hoisting frame and wire fixing clamp, described base is the groove that Open Side Down, the sidewall of described base arranges fastening screw, described screw tip arranges push pedal, and described base is arranged at hoisting frame centre position, and described hoisting frame two ends arrange carries line apparatus, the described line apparatus of carrying is made up of roll, described in carry line apparatus lower end wire fixing clamp be set.

Described wire fixing clamp is made up of clip and wire fixing device, and described wire fixing device is two arcuation slide blocks, and described slide block is arranged at respectively two jaws middle parts of clip by hard spring.

Described jaws end arranges a screwed hole is all set, and in described screwed hole, runs through screw rod is set.

The described line apparatus sidewall of carrying arranges handle.

The beneficial effects of the utility model are: by being arranged at the groove that in the middle of hoisting frame, Open Side Down, and be arranged on the clamp nut with push pedal in recess sidewall, can easily the utility model be installed on the cross-arm of different size.Described wire fixing clamp is made up of clip and wire fixing device, this structure is in the time carrying line, the handle that only need move clip opens two jaws, be inconjunction with that to be arranged at the slide block at two jaws middle parts also separated from one another, the wire that need are promoted is positioned between two arc shaped sliders, unclamp the handle of clip, now, wire to be hoisted is realized fixing under the elastic force of hard spring and the acting in conjunction of clip, the structure simultaneously linking together by spring and jaws due to two slide blocks, can effectively reduce wearing and tearing and the destruction of fixture to lead body.Finally, until lifting wire, to top, the handle of moving clip can take off wire, and in the lifting process of wire, is arranged at locking closing device between two jaws and also can further prevents the landing of wire.In a word, the utility model one people can be fast and without wearing and tearing by lifting wire to shaft tower top, greatly improved the efficiency of stringing, be convenient to promote the use of.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the utility model will be further described:

Fig. 1 is the structural representation of the utility model wire lifting device;

Fig. 2 is the structural representation of the utility model wire fixing clamp jaws.

Embodiment

As shown in Figure 1 and Figure 2: a kind of wire lifting device, comprise base 1, hoisting frame 4 and wire fixing clamp, described base 1 is the groove that Open Side Down, the sidewall of described base 1 arranges fastening screw 3, the top of described screw rod 3 arranges push pedal 2, can easily the utility model be fixed on the cross-arm of different size by adjusting push pedal 2.Described base 1 is arranged at the centre position of hoisting frame 4, and the bottom, both sides of described hoisting frame 4 arranges respectively one and carries line apparatus, described in carry line apparatus lower end wire fixing clamp is set.Wherein, carry line apparatus and formed by roll 5 and the handle 6 that is coupling with it, can realize fast the lifting of wire by swing handle 6; Described wire fixing clamp is made up of clip 7 and wire fixing device, and described wire fixing device is two arcuation slide blocks 9, and described slide block 9 is arranged at respectively two jaws middle parts of clip by hard spring 8.In addition, described jaws end arranges a screwed hole is all set, and runs through screw rod 10 is set in described screwed hole, and this structure can further prevent the landing of wire in lifting process, the fail safe while improving operation.

The utility model in use, is first placed on base 1 on cross-arm, push pedal 2 is compressed to cross-arm sidewall and tighten screw rod 3 and realize the fixing of base; Then wire fixing clamp is dropped to ground by swing handle 6, the handle that staff below being now positioned at moves clip 7 opens two jaws, be inconjunction with that to be arranged at the slide block 9 at two jaws middle parts also separated from one another, the wire that need are promoted is positioned between two arc shaped sliders 9, unclamp the handle of clip 7, now, wire to be hoisted is realized fixing under the elastic force of hard spring 8 and the acting in conjunction of clip 7, because two slide blocks 9 link together by spring 8 and jaws, this structure can effectively reduce wearing and tearing and the destruction of fixture to lead body simultaneously; Finally, top staff's swing handle 6, by lifting wire, to top, the handle of moving clip 7 can take off wire.In addition,, in the lifting process of wire, run through being arranged between two jaws screw rod 10 and can, by closed jaws locking, can further preventing the landing of wire.
