Abstract
The utility model discloses a lead sag measuring device which includes a cross bar and a vertical bar. The cross bar and the vertical bar are connected together via a bolt and a nut. The vertical bar is provided with a bolt slideway. Two vertical edges of the vertical bar are provided with measuring scales. The cross bar is in a concave structure. The vertical bar is embedded in a groove of the cross bar, so the cross bar and the vertical bar are perpendicular to each other. Each lead sag measuring span needs two lead sag measuring devices, i.e. the lead sag in the span can be measured out as long as each of two electric poles in the measuring span is provided with the lead sag measuring device. The vertical bar is provided with the measuring scales. In measurement, the cross bar is fixed on a specified sag scale, when the cross bars of the two measuring devices and the lowest sagging point of the lead are in a straight line, the radian of the lead is adjusted to a predetermined requirement. The lead sag measuring device is simple in structure, accurate in measurement, excellent in effect, and is easy to use.
Description
One, technical field:
The utility model relates to a kind of measurement mechanism, particularly relates to a kind of lead sag measurement mechanism that is used for measuring the outdoor aerial line-sag.
Two, background technology:
The lead sag is meant on smooth ground, when adjacent two basic electric pole upper conductor suspension heights are identical, and the vertical range of line between lead minimum point and two hitch points.In construction of line work progress in the past, adhere to specification in order to guarantee the lead sag, generally be employed in and hang nylon rope on the lead, measure the method for nylon rope length then and measure the actual sag of lead.This method error in the ordinary course of things can be controlled in the scope of permission, but error will be very big under the situation of wind having, and exceeds the error allowed band, thereby make the actual sag of lead not meet designing requirement.
Three, utility model content:
The utility model technical matters to be solved is: overcome the deficiency of prior art, a kind of simple in structure, easy to use, accurate lead sag measurement mechanism of measurement is provided.
The utility model is that the technical scheme that the technical solution problem is taked is:
A kind of lead sag measurement mechanism contains cross bar and montant, and said cross bar and montant link together through screw bolt and nut, and said montant is provided with bolt slide channel, and said montant two vertical edges are provided with the measurement scale.
Said cross bar is " recessed " font structure, and said montant is embedded in the groove of cross bar, and is orthogonal with cross bar.
The utility model is simple in structure, and is easy to use, measures accurately.During measurement, each lead sag is measured span needs two subpolygon sag measurement mechanisms, all will use a pair above promptly measuring every of two electric pole in the span, just can measure the sag of the lead in this span.The montant of the utility model is provided with the measurement scale; During measurement the cross bar of the utility model is fixed on sag (design code value) scale of regulation; During observation; When the sagging minimum point of the cross bar upper edge of two secondary measurement mechanisms and lead was in alignment, the radian adjusted that lead then is described was to predetermined requirement.
Four, description of drawings:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the sectional view at A-A place among Fig. 1.
Five, embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
Referring to Fig. 1 and Fig. 2, a kind of lead sag measurement mechanism contains cross bar 1 and links together through bolt 4 and nut 6 with montant 2 with montant 2,2 said cross bars 1, and said montant 2 is provided with bolt slide channel 3, and 2 liang of vertical edges of said montant are provided with measures scale 5; Said cross bar 1 is " recessed " font structure, and said montant 2 is embedded in the groove of cross bar 1, and is orthogonal with cross bar 1.
During measurement, each lead sag is measured span needs two subpolygon sag measurement mechanisms, all will use a pair above promptly measuring every of two electric pole in the span, just can measure the sag of the lead in this span.The montant 2 of the utility model is provided with measures scale 5; During measurement the cross bar 1 of the utility model is fixed on sag (design code value) scale of regulation; During observation; When the sagging minimum point of cross bar 1 upper edge of two secondary measurement mechanisms and lead was in alignment, the radian adjusted that lead then is described was to predetermined requirement.
