Description

Universal 500kV straight lines wineglass tower line maintenance cross-arm hanging point device
Technical field
The utility model belongs to electric power transmission line repairing auxiliary device technical field, is mainly used in 500KV straight line wine Cup tower line maintenance.
Background technology
In the work of 500KV straight line wineglass towers line maintenance, due on tower head cross-arm steel without fixing device, so maintenance The interim installation cross-arm hanging point system on angle steel is needed during work.Current way has two kinds, and a kind of is steel wire as shown in Figure 1 Rope winding method, angle steel B is padded with two sleeper A, then constitute a hanging point system by steel cable C set winding parcels.But due to tower material Species is more, and angle steel is usually mismatched with sleeper, sleeper can not fully wrapped around angle steel, cause steel rope sleeve and angle steel to there is shearing point Angle, causes stress concentration, easily occurs the stranded phenomenon of individual wire, due to using winding form, and long-term use causes abrasion, It may be broken during insulator is changed because stress is excessive, there is potential safety hazard.And it is disconnected to there is safety in steel rope sleeve When not scrapped below silk number, not readily portable and easy scratch staff's skin.In addition, steel rope sleeve is flexible, work When winding take a lot of work it is laborious;When material prepares, because steel rope sleeve length is unadjustable, steel rope sleeve is chosen long or too short all by directly Connect influence work on the spot.Another is long U-loop method as shown in Figure 2, and upper fastener E way is matched somebody with somebody with lengthening shape U rings D, for The cross-arm of single fixed width, this method is better than wirerope-winding method, but adaptability is not strong, and can be produced in maintenance process Life horizontally slips, beated and resonance phenomenon, there is great potential safety hazard.
The content of the invention
The purpose of this utility model is that there is provided one kind is easy to install and use, safe and reliable, logical for solution the deficiencies in the prior art With the strong 500kV straight line wineglass tower line maintenance cross-arm hanging point devices of property.
The purpose of this utility model is achieved through the following technical solutions:
Universal 500kV straight lines wineglass tower line maintenance cross-arm hanging point device, includes wing main body deck, circle silk braid, T Shape threaded screw rod, anti-jumping clamping plate, hexagonal silk head, U-shaped link component, handle;Circle silk braid is crimped on wing master by tight fit Fixed in the middle of body deck and by screw, T-shaped threaded screw rod passes vertically through round silk braid and is connected each other by screw thread, in T Anti-jumping clamping plate and the hexagonal silk head positioned at anti-jumping clamping plate bottom are set with the middle part of shape threaded screw rod, in T-shaped threaded screw rod Bottom fitting on U-shaped link component is installed, U-loop axle that the U-shaped link component includes being arranged on bottom fitting, two U-loop of the headgear on U-loop axle;Transverse handle is fitted with the top of T-shaped threaded screw rod.
The utility model has advantages below:
1. the present apparatus systematically solves in 500KV straight line wineglass tower line maintenances hanging point device at back-to-back angle cross arm The problem of existing, it is adaptable to the combination of a variety of angle steel width and height, with strong adaptability, the characteristics of highly versatile.
2. the present apparatus is compared with tradition is using steel wire loop working system, high, safe with easy for installation, lightweight, intensity The advantages of property is high, easy to carry, alleviates the labor intensity of workman, shortens the repair time, improve operating efficiency.
3. the present apparatus is compared with long U-loop method, there is wide adaptability, safe, easy for installation, eliminate U The bob that occurs in shape ring working system and the drawbacks of horizontally slip, more reasonable structure, intensity is higher, it is ensured that power circuit Service work safety.
Brief description of the drawings
Fig. 1 is the schematic diagram of wirerope-winding method;
Fig. 2 is the schematic diagram of long U-loop method;
Fig. 3 is structural representation of the present utility model;
Fig. 4 is Fig. 3 right view;
The utility model is installed on original state figure, peace on tower head angle steel by Fig. 5-1, Fig. 5-2, Fig. 5-3 when being maintenance Fill state diagram and use state figure.
Embodiment
Universal 500kV straight lines wineglass tower line maintenance cross-arm hanging point device as shown in Figure 3, Figure 4, includes wing master Body deck 1, circle silk braid 2, T-shaped threaded screw rod 3, anti-jumping clamping plate 4, hexagonal silk first 5, U-shaped link component, handle 10;Circle silk braid 2 It is crimped in the middle of wing main body deck 1 and is fixed by screw 6 by tight fit, T-shaped threaded screw rod 3 passes vertically through round silk braid 2 And be connected each other by screw thread, it is set with anti-jumping clamping plate 4 and positioned at anti-jumping clamping plate at the middle part of T-shaped threaded screw rod 3 The hexagonal silk first 5 of bottom, is provided with U-shaped link component, the U-shaped link component bag on the bottom fitting 7 of T-shaped threaded screw rod Include the U-loop 9 that the U-loop axle 8 on bottom fitting, two are sleeved on U-loop axle;At the top of T-shaped threaded screw rod Transverse handle 10 is fitted with, transverse handle outer end is fitted with stop nut 11.
Application method of the utility model in maintenance is as follows:The present apparatus need not separate each portion when installing, such as Fig. 5-1 Shown, original state rotates anti-jumping clamping plate 4, makes the width of anti-jumping clamping plate 4 and the back-to-back angle steel width side of tower head To alignment, the utility model device is put into back-to-back angle steel gap;As shown in Fig. 5-2, anti-jumping clamping plate is rotated during installation 4, the length direction of anti-jumping clamping plate 4 is alignd with the back-to-back angle steel width of tower head, rotary handle 10 or hex nut 5, Wing deck 1 and the spacing of anti-jumping clamping plate 4 are tightened up, the utility model is firmly arranged on tower head angle steel, hanging point device is installed Complete, immediately into the working condition as shown in Fig. 5-3.After end-of-job, during dismounting such as above-mentioned inverted sequence operation both may be used.
The utility model wide adaptability, highly versatile, apply to the back-to-back angle steel spacing of cross-arm more than or equal to 48 millimeters, The universal hanging point device of angle steel height model 50-220 interval all standings, solve width between tower head cross-arm angle steel do not wait, angle The problem of hanging point device that steel profile is various and brings is difficult to specification and the potential safety hazard of presence.
