Wherein, the transverse roller and the longitudinal roller are made of nylon materials.
The hinge joint of the transverse bracket of the concave roller group and the top end of the shaft bracket in the pulley is provided with a rotary bearing, and the rotary bearing is provided with a fixed-angle bolt so as to fix the transverse bracket of the concave roller group and the shaft bracket in the pulley at any angle.
Wherein every line assembly pulley of walking includes two pulleys, and these two pulleys demountable installation are on the pulley mounting bracket.
The utility model provides a transmission line has a power failure and stridees across light-duty line frame more, can realize through the pulley axis that this light-duty line frame more links to each other with the ground wire of strideing across power failure overhead line, adopt the triangle-shaped base to realize the removal and the anchor of acting as go-between of this light-duty line frame more, can adjust the angle of concave type roller train through swivel bearing and fixed angle bolt synergism, the messenger is put the wire by the exhibition and passes through perpendicularly, still effectually prevents the wire whereabouts that the windage caused to the protection is strideed across overhead line and wire and is not harmd.

Detailed Description
The utility model provides a light-duty line frame that crosses of transmission line power failure leap, including concave type roller train 1, this concave type roller train 1 includes rectangular horizontal support 3, epaxial through bearing or axle sleeve installation have can the rotation horizontal gyro wheel in this horizontal support 3 middle, four angles of this horizontal support 3 are equipped with vertical support respectively, epaxial also through bearing or axle sleeve installation have the vertical gyro wheel that can the rotation in the middle of every vertical support, aforementioned 3 middle parts of horizontal support of this concave type roller train 1 articulate 4 tops of pedestal in a pulley, left side on pedestal 4 in this pulley, the line assembly block is installed respectively on the right side, thereby can press from both sides the wire and remove in the middle of two line assembly blocks of walking, 4 bottoms of pedestal are connected with triangle-shaped base 5 is fixed (for example welding) in this pulley, be connected with insulating rope on this triangle-shaped base 5.
The transverse roller and the longitudinal roller are both nylon Long Caizhi, the rotary bearing 2 is arranged at the hinged position of the top end of the shaft frame 4 in the pulley on the transverse bracket 3 of the concave roller group 1, and the fixed-angle bolt is arranged on the rotary bearing 2 so that the transverse bracket 3 of the concave roller group 1 and the shaft frame 4 in the pulley can be fixed or loosened at any angle.
Wherein every walks the line assembly pulley and include upper and lower totally two pulleys and be the nylon material in addition, these two pulleys pass through pin demountable installation on pulley mounting bracket.
The utility model discloses a use method and theory of operation are:
when transmission line has a power failure to stride across in needs, according to being put the wire walking direction and being strideed across the crossing angle that has a power failure overhead line by the exhibition, adjust earlier the utility model discloses angle between 4 of pedestal in concave type wheel train 1 and the pulley of line frame more to with this angle of fixed angle bolt fastening, ensure that the wire is perpendicular through this line frame plane more.
And then the light-weight line crossing frame is arranged on the ground wire of the crossed power failure overhead line through the two routing pulley blocks on the shaft bracket 4 in the pulley, namely the ground wire is clamped between the two routing pulley blocks. And then the crossing cable frame is dragged to a cross crossing point by the temporary stay wire pulling action connected to the triangular base 5, so that the lead (ground wire) is ensured to pass right above the crossing cable frame, and the isolation supporting action is realized, thereby ensuring that the lead can pass safely and smoothly and the crossed power failure overhead line is not damaged.
The safety of the light-weight wire crossing frame is effectively realized through the concave roller group 1, so that the unfolded wires pass through the concave groove. The lower side nylon roller plays a role in isolating and supporting. The left and right sides gyro wheel plays and stops the effect, reduces windage yaw influence, and the effectual wire jumper that prevents has ensured the security that the power failure strideed across. By adopting the nylon material and the roller design, when the wire touches the light-duty line crossing frame, the contact point surface is rolling friction, thereby greatly reducing the abrasion, prolonging the service life of the light-duty line crossing frame and reducing the abrasion of the wire.
The concave roller group at the top can rotate 360 degrees through the rotary bearing 2, and the angle between the concave roller group and the top of the light-duty line crossing frame is fixed through the fixed-angle bolt. The rotating bearing 2 and the fixed-angle bolt cooperate to meet the requirement of crossing the crossing angle at will and ensure that the lead vertically passes through the plane of the light-weight crossing wire rack. The light-weight wire crossing frame is connected with the ground wire of the crossed power-off overhead line through the two groups of pulleys, and the connection is simple and firm. The temporary stay wire of the triangular base 5 is pulled manually, the pulley middle shaft pulley block moves left and right on the ground wire of the spanned power-off overhead line, the movement is convenient, and the nylon material does not damage the spanned overhead line ground wire.
