Problems solved by technology
Due to the dominance of human subjective factors and the lack of reference, it can only rely on visual and measurement positioning, which is prone to errors. Therefore, misalignment often occurs after the positioning plate is overhauled, and the coaxiality and straightness of the small wheels are affected after installation. impact, easy to damage the small wheels, shorten the production cycle, and increase the frequency of maintenance

Embodiment Construction
[0015] figure 1 It is the front view of the present invention, figure 2 It is a side view of the present invention, as shown in the figure: the trolley wheel bracket positioning plate correction device of this embodiment includes a bracket-type base 1 and four correction surfaces 2 fixedly arranged on the base, and the bracket-type base 1 includes Two isosceles trapezoidal side frames 4 and more than four cross struts 3, the extension lines on both sides of the isosceles trapezoidal side frame 4 intersect at right angles to ensure that both sides of the isosceles trapezoidal side frame 4 fully fit with the small wheel bracket during use, To ensure the accuracy of calibration; two side frames 4 are symmetrically arranged in parallel, and are fixedly connected by cross braces 3. The four cross braces 3 are respectively connected to the four corners corresponding to the two isosceles trapezoidal side frames 4 and are perpendicular to the plane where the two sides are located. T...

The present invention discloses a correction device for a small wheel bracket positioning plate of a traveling crane which comprises a basal body and four correction planes fixed on the basal body; the position relationship of the four correction planes on the basal body is same as that of internal sides or external sides of the four correction planes of the traveling crane small wheel bracket onthe small wheel bracket; the present invention adopts a positioning plate structure which is corresponded to the side of the traveling crane small wheel bracket positioning plate; the positioning plateis corrected into a standard position forcibly and welded while welding and the proper replacement of the positioning plate is guaranteed after being corrected, so negative influences to the using of the small wheel can not be produced which eliminates various mechanical problems caused by improper positioning.
Description
technical field [0001] The invention relates to a positioning device for maintenance of a vehicle, in particular to a correction device for a positioning plate of a small wheel bracket of a vehicle. Background technique [0002] Cranes (overhead cranes) play an irreplaceable role in production-oriented enterprises, especially metallurgical enterprises with heavy materials or finished products and in the maintenance process of large machinery. The crane is composed of bridge frame and trolley. The main girder on the bridge frame is also equipped with rails. The trolley walks on the main girder. The winch mechanism on the trolley retracts and releases the wire rope, and drags the hook up and down to realize the lifting of the goods. . The four small wheels are independently installed on the bottom of the trolley through the brackets. Four positioning plates are fixed on the brackets. The outer rings of the bearings on both sides of the small wheels are fixed on the positionin...
