Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is using state schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is done with detailed description:
As shown in Figure 1, cross arm of tower bracing means described in the utility model, comprise the track 2 be slidably connected with slide plate 8, the shaft tower brace fixed structure 1 that track 2 is arranged by two ends is fixed on shaft tower brace, be provided with the drive unit with locking mechanism in slide plate 8, slide plate 8 moves along track 2 under drive unit drives; Slide plate 8 surface is hinged by rotating shaft 4 with one end of support bar, and the other end of support bar is fixed on cross arm of tower end by the cross arm of tower fixed structure 7 arranged.
In the utility model, drive unit can adopt the drive motors 10 being provided with electromagnetic brake brake, is no longer moved with the position of track 2 is fixing to realize drive unit power-off tail skid 8.The output shaft front end of drive motors 10 is provided with driven wheel 3, and the tooth that driven wheel 3 is arranged with track 2 surface is meshed.Drive motors 10 also can adopt the motor with other locking mechanisms or brake structure, as long as can realize motor power-off rear output shaft by locked function.
In order to carry out the adjustment of support bar length according to actual user demand, in the utility model, support bar adopts the nested type expansion link with retaining mechanism 6, nested type expansion link is divided into outer bar 9 and interior bar 5, the opening part of outer bar 9 is provided with retaining mechanism 6, interior bar 5 is slidably connected by retaining mechanism 6 and outer bar 9, and namely, bar 5 stretches out or enters the inner chamber of outer bar 9.When retaining mechanism 6 unclamps, interior bar 5 and outer bar 9 freely can change under the effect of external force (such as gravity), to realize freely changing of support bar length; When retaining mechanism 6 is locked, the relative position of interior bar 5 and outer bar 9 is fixed, to realize the fixing of support bar length.In the utility model, retaining mechanism 6 can adopt electronics band-type brake, and other also can be adopted can to realize the device of electric control locking.
In the utility model, shaft tower brace fixed structure 1 can adopt the fixing chuck plate being provided with screw, and fixing chuck plate is fixed by bolt and shaft tower brace, finally realizes the fixing of track 2 two ends and shaft tower brace.Cross arm of tower fixed structure 7 can adopt the fixing chuck plate being provided with screw, and fixing chuck plate is fixed by bolt and cross arm of tower.The top of the interior bar 5 of nested type expansion link is hinged by rotating shaft 4 and slide plate 8 upper surface, and the bottom of the outer bar 9 of nested type expansion link is fixed by cross arm of tower fixed structure 7 and cross arm of tower.
As shown in Figure 2, the utility model when mounted, first shaft tower brace fixed structure 1 is utilized the first end of track 2 and the second end to be fixed with the side a and b of shaft tower brace AB respectively, then outer bar 9 bottom of nested type expansion link is held fixing by cross arm of tower fixed structure 7 and the C of cross arm of tower AC, finally slide plate 8 is moved to the least significant end of track 2, in the present embodiment, slide plate 8 is moved to the first end of track 2.Above-mentioned operation is installation procedure of the present utility model.
When shaft tower location runs into high wind or snowfall attacks, the load that cross arm of tower AC bears will significantly promote, and exist and destroy risk greatly.Now, the electronics band-type brake that first staff controls nested type expansion link is arranged opens, and the length of nested type expansion link freely can be changed under the effect of external force; Then after staff makes slide plate 8 move to the middle part of track 2 by the drive motors 10 controlling to be provided with electromagnetic brake brake, close the power supply of drive motors 10 again, keep immobilizing with track 2 position at the effect lower skateboard 8 of electromagnetic brake brake, and nested type expansion link can realize length according to the movement of slide plate 8 position and automatically adjusts in slide plate 8 moving process; Finally, staff controls the electronics band-type brake locking that nested type expansion link is arranged, and the length of nested type expansion link is fixed.
By above-mentioned steps, the utility model can form new braced structures to cross arm of tower AC, by the redistribution of counter stress, makes the load of cross arm of tower AC be dispersed to other rod members, cross arm of tower AC can be avoided to destroy.
After high wind or snowfall terminate, the electronics band-type brake that staff can control nested type expansion link is arranged opens, and the length of nested type expansion link freely can be changed under the effect of external force; Then staff makes slide plate 8 re-move least significant end to track 2 and first end by the drive motors 10 controlling to be provided with electromagnetic brake brake, close the power supply of drive motors 10 again, under the effect of electromagnetic brake brake, make slide plate 8 and track 2 position keep immobilizing, in slide plate 8 moving process, nested type expansion link can realize length according to the movement of slide plate 8 position and automatically adjusts; Finally, staff controls the electronics band-type brake locking that nested type expansion link is arranged, and the length of nested type expansion link is fixed.
By above-mentioned steps, the braced structures that can make to utilize the utility model to be formed disappears, and now the load that bears of cross-arm AC is within its allowed band.
In sum, the utility model based on the reinforcing realizing cross arm of tower of load redistribution principle, effectively can solve the problem that transmission tower cross-arm damages under severe conditions, ensures the safety of cross arm of tower, can be widely used in various transmission tower.
