Description of drawings
The accompanying drawing that constitutes the application's a part is used to provide further understanding of the present utility model, and illustrative examples of the present utility model and explanation thereof are used to explain the utility model, do not constitute improper qualification of the present utility model.In the accompanying drawings:
Fig. 1 is that electric wire is arranged synoptic diagram in the prior art;
Fig. 2 is the structural representation of the utility model preferred embodiment; And
Fig. 3 is the crane span structure plan structure synoptic diagram of the utility model preferred embodiment.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
As shown in Figure 2, the utility model provides a kind of rocker-arm crane span structure mechanism, and this crane span structure mechanism comprises support 10, stands on the predeterminated position of testing table 50; Rotating shaft 20 vertically is arranged on the support 10; Crane span structure 30, its first end links to each other with rotating shaft 20, its second end along continuous straight runs stretches out and is that the center rotates in surface level with rotating shaft 20, certainly, rotating shaft 20 also can and support 10 between have certain angle of inclination.
Electric wiring is erected and under the guiding of crane span structure 30 electrical wire extended near the equipment to be tested by support 10 and crane span structure 30, utilize rotating shaft 20 to make crane span structure 30 with certain angle rotation, can effectively avoid interference to all the other mechanical pipelines, need not to dismantle repeatedly electric wiring, improve testing efficiency.
Installation and removal for the ease of electric wiring; and electric wiring played the certain protection effect, and crane span structure lid 31 can be set on the crane span structure 30, crane span structure lid 31 can have the installation limit of downward extension; the sidewall that limit and crane span structure 30 are installed is stacked, and is fixing by bolt 33 again.
For the installation that makes support 10 more firm, the bottom of support 10 can be provided with carrier base 13, carrier base 13 is provided with bolt hole, in the time of support 10 need being installed in certain position on the testing table 50, can squeezing into bolt in the bolt hole on the carrier base 13 and locate.
In order to realize that crane span structure 30 is the purpose that the center is rotated with rotating shaft 20, one side of the upper end of support 10 is set with axle bed 21, axle bed 21 is passed in rotating shaft 20 and axle bed 21 is rotatable relatively, and the upper end of rotating shaft 20 links to each other with first end of crane span structure 30, and the lower end of rotating shaft 20 is positioned at axle sleeve 23.
Under the situation that adopts above-mentioned rotating shaft mounting means, the crane span structure bottom surface 35 of crane span structure 30 should be higher than the upper surface of column 10, with the sidewall that prevents support 10 rotation of crane span structure 30 is caused restriction.In order to prevent that the corner of electric wire between support 10 and crane span structure 30 from causing damage, the vertical projection of the crane span structure bottom surface 35 of crane span structure 30 should be positioned at the outside of the gathering sill of support 10, that is to say that the crane span structure bottom surface 35 of crane span structure 30 had better not cover support 10.
As shown in Figure 3, in order to prevent being scratched by the cross section of the crane span structure bottom surface 35 of crane span structure 30 of crane span structure 30 in the electric wire bending place, the end face of first end of crane span structure 30 is circular arc, and can on the end face of first end of crane span structure 30 flexible piece 32 be set, this flexible piece 32 can have the material of certain resiliency flexible degree for rubber strip etc.
In order to prevent that having less parts or dust granules etc. to enter in the process of the test causes damage to electric wire in the column; crane span structure lid 31 can be provided with overhanging cover 31a near an end of rotating shaft 20; this overhanging cover 31a should be positioned at support 10 tops, to play the effect of protection electric wire.
Rotating shaft 20 in the utility model preferred embodiment is installed in a side of column 10, and the height between crane span structure 30 and the pillar 10 is had certain requirement.In fact, rotating shaft also can directly be set in the periphery or the interior week of column 10, and the upper end of rotating shaft and the design of crane span structure one, that is to say that rotating shaft is the part of crane span structure body, when column fixedly the time, but rotating shaft is with respect to the column coaxial rotation, and crane span structure is the center rotation with the rotating shaft.But the crane span structure mechanism of this kind form is higher to the intensity and the performance requirement of each parts, and the matching degree between column and the crane span structure requires high, and cost is higher.
The above is a preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
