Detailed Description
The invention is described in further detail below with reference to the following figures and examples:
fig. 1 and 2 show a convenient leveling device for an urban rail vehicle body supporting platform, wherein the vehicle body supporting platform comprises four vehicle body supporting sub-platforms 2; the leveling device comprises four measuring pipes 1, four measuring pipes 1 can be stably arranged on four sides of the vehicle body supporting sub-platform 2 respectively.
The measuring pipe 1 is provided with a liquid level observation window, and the height difference between the liquid level in the measuring pipe 1 and the top end surface of the vehicle body supporting sub-platform 2 can be accurately observed through human eyes;
the leveling device is characterized by further comprising an adjusting pipe 4, wherein the adjusting pipe 4 is communicated with the four measuring pipes 1 through communicating pipes 3, and an operator can inject observation liquid with a target amount into the leveling device or adjust the amount of the observation liquid.
Survey buret 1 and adjusting tube 4 and for taking the transparent hard tube of scale, will more convenient operation when we need adjust the volume of surveying liquid in surveying the buret after taking the scale, transparent hard tube also makes things convenient for very much that the operator observes survey buret 1 and the automobile body supports the difference in height of dividing platform 2 top end face. However, the measuring tube 1 of other materials may be used depending on the design and requirements, as long as the measuring tube 1 has a liquid level observation window, and the height difference between the liquid level in the measuring tube 1 and the top end surface of the vehicle body support sub-platform 2 can be accurately observed by human eyes.
Due to the difference between the design and the requirements, the adjusting pipes 4 are not needed to be arranged, and the four measuring pipes 1 can be communicated with each other through the communicating pipes 3, so that the liquid level inside the four measuring pipes 1 is at the same horizontal height after the measuring pipes 1 are filled with the observation liquid with the target amount. Certainly, the adjusting pipe 4 is arranged, the operation is more convenient and reasonable, and the liquid level observation of the measuring pipe 1 cannot be influenced by injecting observation liquid and adjusting the observation liquid.
The communicating pipe 3 is a hose, and because the four car body supporting sub-platforms 2 are far away from each other, and the distance L in the length direction is 8084mm, the measuring pipe 1 and the adjusting pipe 4 are communicated by the hose more flexibly and conveniently.
The observation liquid is red ink, and other colors can be selected according to different colors of the working environment, so long as the colored ink solution is convenient for an operator to observe.
The method for leveling by using the convenient leveling device of the urban rail vehicle body supporting platform comprises the following steps:
a. the four measuring tubes 1 are respectively and stably arranged near the four vehicle body supporting sub-platforms 2, so that the height difference between the liquid level in the measuring tubes 1 and the top end surface of the vehicle body supporting sub-platforms 2 can be observed conveniently;
b. injecting the observation liquid into the four measuring tubes 1 until the liquid level in each measuring tube 1 reaches a target height;
c. comparing the height difference between the top end surface of the vehicle body supporting sub-platform 2 and the liquid level in the measuring pipe 1;
d. and adjusting the height of the vehicle body supporting sub-platform 2 by using a 1mm gasket to enable the height of the top end surface to be flush with the height of the liquid level in the measuring pipe 1.
When the leveling device is provided with the adjusting pipes 4, the observation liquid is injected into the four measuring pipes 1 in the step b by injecting the observation liquid from the adjusting pipes 4.
The target height in the step b can be the height of the highest vehicle body supporting sub-platform 2 in the four; and then the heights of the top end surfaces of the other three vehicle body supporting sub-platforms 2 are adjusted and lifted one by one in the step d.
Of course, the target height may also be a height higher than all the car body supporting sub-platforms 2, and then the height of the top end surface of the four car body supporting sub-platforms 2 is adjusted and raised in step d one by one until the height is flush with the liquid level in the measuring pipe 1.
Therefore, the height of the four vehicle body supporting sub-platforms 2 which are quickly leveled can reach the same accurate level height, although the maximum distance of the four vehicle body supporting sub-platforms is 8084mm, the height error is only 1mm, and the leveling accuracy is greatly improved.
The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
