Description

Electrified Catenary Pillar Slope Measuring Ruler

technical field

The utility model relates to an installation tool for an electrified catenary support, in particular to a measuring ruler for measuring the slope of the electrified catenary support.

Background technique

In the construction of electrified catenary, the installation of pillars is essential, and whether the installation of pillars meets the design requirements will directly affect whether the train can run normally after it is put into operation. Whether the slope of the pillar meets the design requirements is an important technical index to evaluate the installation quality of the pillar, so it is very important to measure the slope of the pillar accurately and quickly. Up to now, the slope measurement of the pillar is still in the state of hanging the pendant, that is, the line pendant is put down vertically from the top of the pillar, and the vertical displacement of the line pendant is calculated by measuring the horizontal displacement between the line pendant and the side of the pillar and the numerical height of the line pendant. actual slope. Using this primitive tool to measure the slope of the pillar is not only labor-intensive and time-consuming, but also difficult to achieve accurate measurement because the measurement result will be affected by the external environment such as wind direction and wind force.

Utility model content

The purpose of the utility model is to provide a slope measuring ruler which can accurately, simply and quickly measure the slope of the electrified catenary pillar, so as to improve the construction efficiency.

The utility model is achieved in that:

The electrified catenary pillar slope measuring ruler is provided with a vertical positioning mechanism at the bottom of the vertical positioning ruler body, and a scale ruler orthogonally connected with the body at the top.

Attach the bottom end of the positioning ruler vertically to the side of the pillar. After the vertical positioning mechanism confirms that the positioning ruler is in a vertical state, turn the scale that is perpendicular to the body of the positioning ruler so that the end of the scale reaches the side of the pillar. At this time, the ratio of the length of the protruding scale to the length of the positioning ruler is the actual slope value of the catenary pillar. This value can meet the design requirements, if not, continue to adjust the pillars until the design requirements are met. For the convenience of measuring and calculating the slope value, the utility model can make the length of the aforementioned positioning ruler into 1 unit, so that without calculation, the scale value on the scale is the slope value.

Under above-mentioned technical scheme, the utility model can realize like this:

The vertical positioning mechanism is a horizontal vial fixed on the bottom of the positioning ruler body and a vertical orientation mark.

The utility model adopts this structure, through the level bubble in the horizontal direction and the directional mark in the vertical direction, it can conveniently and intuitively determine whether the whole vertical positioning ruler is in the vertical state with the ground, so that the operation is very convenient and quick.

The utility model directly reads data, is easy to use, is not affected by field weather conditions during use, and has the advantages of accurate and fast measurement. The utility model has a simple overall structure and is convenient to carry and use in field operations. Owing to being economical and practical, the measuring ruler is very suitable for popularizing and using in a large area.

Description of drawings

Fig. 1 is a structural representation of the utility model.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

Shown in Fig. 1, this electrified catenary pillar slope measuring ruler is that the bottom end of the vertical positioning ruler body 3 is fixed with a horizontal vial 1 and a vertical orientation mark 2. The top of the vertical positioning ruler body 3 is provided with a cylindrical through hole in a direction perpendicular to the positioning ruler body, and a scale 5 is connected through the through hole. The scale 5 is a cylinder with a uniform scale value engraved on the scale. One end is provided with a tapered handle. By rotating the handle, the position of the scale can be adjusted to achieve accurate measurement of the slope of the pillar. A better embodiment is that the positioning nut 4 is screwed on the scale, so as to realize the positioning of the scale 5 or the fine adjustment of the scale.

The utility model can be made of magnesium-aluminum alloy material, the total weight is light, wear-resistant, not easy to be damaged, and is suitable for use in the harsh environment of the construction line.

The slope measuring ruler of the utility model has changed the present situation that one person hangs the pendant, measures by one person, and then calculates the slope. The utility model has the advantages of simple structure, light weight, easy operation and low cost.
