Problems solved by technology

[0003] The original platform is a cast iron platform, and the length of the cast iron platform is 8 meters * 5 meters. The whole cast iron platform needs to be cemented for inlaying and leveling. The cost is relatively high, about 20 million, and the platform needs to be operated by 3 people at the same time

Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings, but it should be pointed out that the implementation of the present invention is not limited to the following embodiments.

[0027] See Figure 1-Figure 6 , a method for measuring the flatness of a rail transit locomotive bogie without a platform, comprising the following steps:

[0028] 1) Laying rubber pads 1 for shock absorption on the field; reducing the degree of damage to the ground;

[0029] 2) place the supporting plate 2 on the rubber pad 1 in the shape of a finished product, so that the rubber pad 1 is partially flat on the supporting plate 2;

[0030] 3) Place thimbles 3 on the supporting plate 2, generally 3 thimbles, which are used together with the supporting plate 2;

[0031] 4) Set two or more laser marking instruments 4 at appropriate positions outside the rubber pad 1, adjust the adjustable bracket 5 of the laser marking instrument 4 to make it hori...

Abstract

The invention relates to a method and device for measuring the straightness of a rail transit locomotive bogie platform without a platform. A rubber mat is laid on the field; a supporting plate is placed on the rubber mat; a thimble is placed on the supporting plate; a laser marking instrument is arranged outside the rubber mat. Adjust the adjustable bracket of the laser marking instrument to make it horizontal and on a plane; hoist the bogie and place it on the thimble; adjust the casting parting surface of the bogie, and the parting surface and the horizontal light emitted by the laser marking instrument coincide until. Its structure includes a rubber pad, supporting plate, thimble, and laser marking instrument. A supporting plate is set on the rubber mat for the finished font, an thimble is arranged on the supporting plate, and a laser marking instrument is installed next to the rubber pad. The advantages are: the rubber pad can reduce the damage to the ground, the supporting plate forms a local stable structure, and then supports the bogie through the thimble to form a temporary measuring platform, which can measure the flatness flexibly and conveniently, and the operation is simple, reducing the number of operators Quantity; tooling is simple, easy to adjust, intuitive.

Description

technical field [0001] The invention relates to a method and device for measuring the flatness of a rail transit locomotive bogie without a platform, in particular to a method for measuring the straightness of a large rail transit locomotive bogie without a platform or the measurement of the flatness of similar large frame castings. Background technique [0002] In the process of producing large-scale castings, the measurement of the flatness of the initial blank of the casting is completely dependent on the large-scale platform. The construction of a large-scale platform has brought enormous pressure to the enterprise in terms of funds, venues, and staffing. [0003] The original platform is a cast iron platform with a length of 8 meters * 5 meters. The whole cast iron platform needs to be cemented for inlaying and leveling. The cost is relatively high, about 20 million, and the platform needs to be operated by 3 people at the same time. Contents of the invention [0004...
