Furthermore, through holes for tying the line weight are symmetrically arranged at two ends of the horizontal part; the center distance of the two through holes is equal to the width of the flange plate on the crane beam to be measured.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Fig. 2 is a schematic view of a usage mode of an embodiment of the present invention.
In the figure: a stabilizing base 1; a vertical portion 2; a horizontal part 3; a line pendant 4; the crane beam 5 to be tested.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
As shown in fig. 1, the auxiliary tool for retesting a crane beam provided in the embodiment of the present invention mainly comprises a stabilizing base 1, a vertical part 2, a horizontal part 3 and a line weight 4.
Wherein, the upper surface of the stabilizing seat 1 is fixedly provided with a vertical part 2, and the upper end of the vertical part 2 is fixedly connected with a horizontal part 3; two ends of the horizontal part 3 are respectively provided with a line weight 4. In the embodiment, the stabilizing seat 1 is of a symmetrical structure, and the stabilizing seat 1 is used for installing the vertical part 2 and the horizontal part 3 and controlling the gravity center of the whole crane beam retest auxiliary tool; so that the auxiliary tool for the retesting of the crane beam provided by the embodiment is not overturned when being placed on the crane beam 5 to be tested.
The vertical part 2 divides the horizontal part 3 into two symmetrical and equal parts, and the line plummets 4 at the two ends of the horizontal part 3 are symmetrical with each other; the length of the horizontal part 3 is equal to the width of the flange plate on the crane beam 5 to be measured. The vertical portion 2 bisects the horizontal portion 3 (the vertical portion is located), and the length of the horizontal portion 3 is equal to the width of the upper flange plate of the crane beam 5 to be tested.
When using the embodiment of the utility model provides a can directly weigh down 4 and the relation and the line of 5 upper limb listrium looks remote site of crane beam 5 that await measuring through the line of observing 3 both ends of horizontal part when detecting and weigh down 4 states and can accomplish the retest of straightness that hangs down.
In the embodiment, the joints among the stabilizing seat 1, the vertical part 2 and the horizontal part 3 are all fixed by welding.
In the process of implementing the present invention, in order to obtain a better technical effect, the following preferred structure may be adopted.
As a preferable structure, the stabilizing seat 1 is made of iron or steel blocks with the length of 100mm, the width of 100mm and the thickness of 50 mm. The use of steel or iron blocks is advantageous for stabilizing the center of gravity of this embodiment.
