Description
Technical Field
The utility model relates to a supplementary cross arm of frame is striden to flexibility.
Background
In the construction process of the ultra-high voltage transmission line, more and more overhead transmission lines are constructed. At present, a flexible spanning frame is generally adopted for live spanning, namely an insulating cable bridge is erected, a spanning gear needs to be hung to assist holding poles before erection construction, auxiliary tools such as the cable bridge need to be installed, and the whole process is complex. The related parts are heavy and bulky, so that high-altitude operation is time-consuming and labor-consuming, and in addition, a certain potential safety hazard also exists due to the adoption of a connection mode of winding the steel wire rope.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a supplementary cross arm is striden to flexibility, the efficiency of erectting that can effectual improvement insulating cable bridge.
A flexible cross-frame auxiliary cross arm is characterized in that: the device comprises a parallel hanging plate, wherein two ends of the parallel hanging plate are respectively provided with a butt joint mounting plate, and the butt joint mounting plate is provided with at least 2 butt joint mounting holes; two ends of the parallel hanging plate are respectively provided with an anchoring plate mounting gap, the anchoring plates are detachably mounted on the mounting gaps through fasteners, 3 through holes are formed in the anchoring plates along the length direction, and the fasteners are mounted on the through holes in the middle; at least 2 vertical guardrails vertical to the parallel hanging plates are detachably mounted on the parallel hanging plates, and a transverse guardrail is detachably mounted at the top ends of the vertical guardrails.
The bottom ends of the vertical guardrails are respectively hinged to the parallel hanging plates, and the hinged parts are provided with limiting plates and buckles, so that the vertical guardrails can be vertically fixed on the parallel hanging plates.
The utility model provides a supplementary cross arm is striden to flexibility, riveting mechanism on this cross arm can realize being connected with iron tower, bearing system, and parallel hanger plate and folding guardrail can provide operation space and support for the high altitude construction personnel, and the interfacing apparatus at both ends has realized the connection between the parallel hanger plate of a plurality of cross arms, has satisfied the construction demand, has guaranteed setting up of insulating cable bridge net. Through the proof on probation, adopt the utility model discloses an insulating cable bridge is erect to one or more flexibility stride the supplementary cross arm of frame, whole simple operation, connect reliable, the security is high, light in weight, small, the effectual efficiency of erectting that has improved insulating cable bridge.

Detailed Description
The utility model provides a flexible cross-frame auxiliary cross arm, which comprises a parallel hanging plate, wherein the general shape of the parallel hanging plate is a strip-shaped steel frame, two ends of the parallel hanging plate are respectively welded with a rectangular butt joint mounting plate 2, and each butt joint mounting plate 2 is provided with 2-4 butt joint mounting holes; at this parallel hanger plate left side, still be equipped with 3 erection gaps of an anchor board in the middle of the steelframe at right both ends respectively, but have a rectangular anchor board 3 through fastener demountable installation on every erection gap, be equipped with 3 through-holes along length direction on every anchor board 3, and foretell fastener just in time is installed on the through-hole that lies in the centre on anchor board 3, and the top through-hole on the remaining anchor board 3 is connected with iron tower main cross arm, and the below through-hole links to each other with the bearing coaster, thereby has realized the utility model discloses a flexibility strides the connection anchor of supplementary cross arm and next door iron tower and bearing system (bearing coaster), simultaneously with parallel hanger plate synergism, still plays bearing rope isolation.
Wherein, at least 2 vertical guardrails 1 vertical to the parallel hanging plate are detachably arranged on the parallel hanging plate, and a transverse guardrail 4 is detachably arranged at the top end of the vertical guardrail 1. Wherein 1 bottom of vertical guardrail articulates respectively on parallel hanger plate to thereby install limiting plate and buckle in articulated department and can be with 1 vertical fixation of vertical guardrail on parallel hanger plate. Thereby constitute unilateral folding guardrail through vertical guardrail 1 and horizontal guardrail 4, provide the handrail for high altitude construction personnel, play the removal supporting role, and unilateral design, operation personnel operation space is unrestricted, and the guardrail below adopts articulated structure, and is collapsible, and the transportation is small, does not account for the space.
The utility model discloses a use method and theory of operation are:
adopt the utility model discloses an insulating cable bridge can be erect to one or more flexibility cross the supplementary cross arm of frame as required length. The utility model discloses two anchor boards 3 in the supplementary cross arm mainly are the realization the utility model discloses a fixed connection between supplementary cross arm and iron tower and the bearing coaster. The parallel hanging plates and the folding guardrails mainly provide operation space and support for operators. Two butt joint mounting panel 2 mainly used realize a plurality ofly the utility model discloses connection between the parallel hanger plate in the cross arm to guarantee that the wire of exhibition putting is in insulating net protection within range.
When the utility model is used, before the live crossing of the power transmission line, the total length of the auxiliary cross arm of the required insulating cable bridge is calculated according to the wind deflection, the width of the main cross arm of the iron tower of the power transmission line, the crossed overhead line and other factors, and the length divided by the parallel hanging plates is generally required. Through butt joint mounting panel 2 and the butt joint mounting hole at parallel hanger plate both ends, the operating personnel assembles flexibility under the tower and strides a supplementary cross arm to corresponding length, the utility model discloses a supplementary cross arm lifts by crane behind the relevant position, is connected work hole (top through-hole) on two anchor boards 3 with the iron tower main material, and high altitude construction personnel pass through the support of hanger plate and guardrail supplementary, is connected work hole (below through-hole) on two anchor boards 3 with the bearing coaster again to realize setting up of insulating cable bridge net, guarantee that the wire of strideing across overhead line and exhibition and putting does not receive the damage.
