Abstract
The utility model relates an auxiliary bracket for maintaining a power transmission line, which comprises a first insulated ladder and a second insulated ladder that are fixedly connected. The first insulated ladder and the second insulated ladder are respectively composed of two parallelly arranged transverse rods. The two transverse rods are fixedly connected through a plurality of uniformly arranged reinforcing ribs. The tail ends of two transverse rods of the first insulated ladder are fixedly connected with the head ends of two transverse rods of the second insulated ladder. An included angle between the transverse rod of the first insulated ladder and the transverse rod of the second insulated ladder is an obtuse angle. The head ends of the two transverse rods of the first insulated ladder are connected with a first self-locking hook therebetween through a rope. The tail ends of two transverse rods of the second insulated ladder are connected with a second self-locking hook through a rope. The auxiliary bracket for maintaining the power transmission line has a simple structure and can provide a force application point for working personnel. Furthermore the auxiliary bracket facilitates power transmission line maintenance by the working personnel. Application of the auxiliary bracket can improve operation efficiency based on high safety of the working personnel.
Description
Technical field
The utility model relates to a kind of auxiliary equipment in electric power system, particularly a kind of auxiliary stand used in the power transmission lines overhauling process.
Background technology
Along with the continuous increase of transmission line length, major repair of track, transformation task also increase the weight of thereupon in recent years, and in the operation of transmission line interruption maintenance, the maintenance of strain rod tower accounts for very large proportion.The upkeep operation of strain rod tower mainly comprises operations such as changing insulator, replacing stockbridge damper, repairing drainage thread, replacing gold utensil.Change the time limit because the synthetic insulator put into operation has in advance reached the cycle in succession in recent years, the workload that transmission line is changed insulator also rises thereupon year by year.When the strain rod tower of large leap, high drop carries out upkeep operation, usually the method that adopts and fix husky bar, tramples wire or climbing insulator is carried out operation, exist force little, be difficult for the shortcomings such as erect-position, operation inconvenience, operating efficiency is low, and coefficient of safety can not get ensureing.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of Stability Analysis of Structures, can provide impetus for the operating personnel, and the power transmission lines overhauling auxiliary stand of convenient working personnel operation.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows.
The power transmission lines overhauling auxiliary stand, comprise the first insulating ladder and the second insulating ladder that are fixedly connected with, and described the first insulating ladder and the second insulating ladder consist of two cross bars that be arranged in parallel respectively, and the many reinforcements by even cloth between two cross bars are fixedly connected with; Be fixedly connected with between two cross bar tail ends of described the first insulating ladder and two cross bar head ends of the second insulating ladder, arrange in obtuse angle between the cross bar of the cross bar of the first insulating ladder and the second insulating ladder; Be connected with the first Self-locking hanging hook by rope between the head end of two cross bars of described the first insulating ladder, between the tail end of two cross bars of the second insulating ladder, by rope, be connected with the second Self-locking hanging hook.
Improvement of the present utility model is: between two links of described the first insulating ladder cross bar and the second insulating ladder cross bar, be provided with connecting rod.
Further improvement of the utility model is: between described adjacent reinforcement, be arranged in parallel, and vertical setting between reinforcement and cross bar.
Angle between the cross bar of the cross bar of the first insulating ladder described in the utility model and the second insulating ladder is preferably 120 °～150 °.
Improvement of the present utility model also is: be pasted with respectively spaced red mark band and yellow mark band on described cross bar and reinforcement.
Owing to having adopted technique scheme, the obtained technological progress of the utility model is as follows.
The utility model is simple in structure, adopts two to be fixedly connected with the also insulating ladder of angled setting, and needed impetus is provided during for operating personnel's operation; The two ends of insulating ladder hang and are fixed on cross-arm by the Self-locking hanging hook with rope respectively, and the stability while having guaranteed the utility model operation, for operating personnel's trouble free service provides assurance.
The utility model is applied on transmission line the device on transmission line is overhauled or changes, and can, on the basis of improving operating personnel's security performance, increase work efficiency.Between two connection end points of the first insulating ladder and the second insulating ladder, adopt connecting rod to be fixedly connected with, effectively guaranteed the bonding strength of two insulating ladders; Equally, adopt the vertical form that arranges between reinforcement and cross bar, also be intended to improve the force intensity that is subject to of the present utility model.The red mark band arranged on cross bar and reinforcement and yellow mark band, play warning function for the other staff to the transmission line below, prevents that non-operating personnel is close, guarantees other people current safety.
The accompanying drawing explanation
Fig. 1: structural representation of the present utility model.
Wherein: 1. the first insulating ladder, 2. the second insulating ladder, 3. cross bar, 4. reinforcement, 5. the first Self-locking hanging hook, 6. the second Self-locking hanging hook, 7. connecting rod.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
