Abstract
The utility model relates to a wind generating set foundation ring levelness measurement device. The wind generating set foundation ring levelness measurement device comprises a levelling instrument, a backing plate and a straight ruler which is provided with a level gauge, the levelling instrument is fixed on a top flange of a foundation ring through a connecting screw rod and a nut, the backing plate is disposed between the top flange of the foundation ring and the nut, and a ruler erector erects the straight ruler with the level gauge at each measuring point of an upper plane of the top flange of the foundation ring. A tower ruler is replaced by the straight ruler with the level gauge, the measurement accuracy of the straight ruler is mm, the measurement accuracy of the tower ruler is cm, thereby the reading accuracy is improved by ten times, the levelling instrument is directly fixed on the top flange of the foundation ring through a connecting bolt which is arranged on the levelling instrument, the accuracy of foundation ring levelness measurement data is improved, and the measuring operation time is shortened.
Description
Technical field
The utility model relates to a kind of foundation ring of wind generating set levelness measuring device.
Background technology
At present, traditional measurement foundation ring levelness method is that the general using spirit-leveling instrument is measured in the industry, be about to spirit-leveling instrument and be placed on the excavation slope by tripod, vertical chi person stands in foundation ring top each measuring point of flange face with Sopwith staff, and the observer reads the scale on the Sopwith staff and records the result.There is following drawback in this metering system:
As the Sopwith staff measuring accuracy of levelling pole be centimetre, millimeter is read for the observer estimates, and vertical chi person is difficult to guarantee the verticality of Sopwith staff, and the accuracy of measurement result is difficult to meet the demands;
Sopwith staff produces swing under the wind effect, cause difficulty for observer's reading, easily produces reading error;
Wind field excavation of foundation pit side slope is with a varied topography, and spirit-leveling instrument is not easy to lay steadily by tripod, spirit-leveling instrument leveling difficulty.The standard of depositing owing to above drawback has caused foundation ring installation level measurement data inexactness, and the safety of fan has stayed hidden danger.
The utility model content
The utility model purpose is to overcome above defective, and a kind of foundation ring of wind generating set levelness measuring device accurate, simple to operate of measuring is provided.
The technical solution of the utility model is: it comprises spirit-leveling instrument, also comprise ruler, backing plate with level, spirit-leveling instrument is fixed on the top flange of foundation ring by connecting screw rod and nut, be provided with backing plate between the top of described foundation ring flange and nut, vertical chi person will stand in the ruler of level each measurement point on upper plane of the top flange of foundation ring.
The beneficial effects of the utility model are, change Sopwith staff into level ruler, because the ruler measuring accuracy is mm, the Sopwith staff measuring accuracy is cm, therefore reading accuracy has improved 10 times; Secondly, ruler is with respect to Sopwith staff, blade volume and front face area reduce greatly, blade kept vertically being difficult to guarantee that Sopwith staff vertically reaches the defective that Sopwith staff swing under the wind effect easily produces reading error thereby overcome traditional foundation ring levelness measuring method when ruler can be guaranteed reading under the effect of level simultaneously; In addition, because spirit-leveling instrument directly is fixed on the flange of foundation ring top by its coupling bolt that carries, thereby improved the accuracy of foundation ring horizontal degree measurement data, and shortened the measurement activity duration.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is fixedly schematic diagram of spirit-leveling instrument;
Wherein: 1, with the ruler of level; 2, vertical chi person; 3, top flange; 4, foundation ring; 5, spirit-leveling instrument; 6, observer; 7, backing plate; 8, connecting screw rod.
Embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.With reference to accompanying drawing, it comprises spirit-leveling instrument 5, ruler 1, backing plate 7 with level, spirit-leveling instrument 5 is fixed on the top flange 3 of foundation ring 4 by connecting screw rod 8 and nut, because the bolt hole of top flange 3 is larger, so be provided with backing plate 7 between top flange 3 and nut, vertical chi person 2 will stand in the ruler 1 of level each measurement point on the upper plane of top flange 3.
During measurement, vertical chi person determines the verticality that ruler is placed by the observation band level, and observer 6 reads the relative altitude H that measures flange 3 each measurement point in top with ruler 1 scale of level by the spirit-leveling instrument 5 that directly is fixed on the top flange 3

The utility model is owing to the ruler 1 that Sopwith staff is changed into level, because the ruler measuring accuracy is mm, the Sopwith staff measuring accuracy is cm, therefore reading accuracy has improved 10 times; Secondly, ruler is with respect to Sopwith staff, blade volume and front face area reduce greatly, blade kept vertically when ruler can be guaranteed reading under the effect of level simultaneously, be difficult to guarantee that Sopwith staff vertically reaches Sopwith staff swing under the wind effect and easily produces the defective of reading error thereby overcome traditional foundation ring 4 levelness measuring methods, thereby improved the accuracy of foundation ring 4 horizontal degree measurement data; In addition, because spirit-leveling instrument 5 directly is fixed on the top flange 3 of foundation ring 4 by its connecting screw rod that carries 8, be difficult to the fixing defective in Anping on the foundation ditch limit thereby overcome spirit-leveling instrument, shortened the measurement activity duration.
More than be a kind of embodiment of the present utility model, a preferred demonstration example.The scope that the utility model application is asked for protection has more than and is limited to described embodiment.All and technical scheme the present embodiment equivalence all belongs to protection domain of the present utility model.
