Locomotive cylinder head hydraulic pressure sealing automatic test platform

Abstract

The invention discloses a locomotive cylinder head hydraulic pressure sealing automatic test platform. The locomotive cylinder head hydraulic pressure sealing automatic test platform comprises a testplatform frame, a test station, a cylinder head supporting and positioning device, a hydraulic pressure sealing test frame and a sealing pressing head lifting device; and a test sealing pressing headis installed at the lower end of the sealing pressing head lifting device and is provided with a pressure water feeding device in a communicating mode, the sealing pressing head lifting device is connected with a hydraulic pump station or an air pressure pump station, and the pressure water feeding device is connected with a high-pressure water pump; the test platform frame is further provided with a cylinder head hoisting device. Firstly, a cooling water feeding hole of the test cylinder head is blocked, the cylinder head hoisting device is used for hoisting a test cylinder head to the cylinder head supporting and positioning device to be supported and positioned, the hydraulic sealing test frame is moved to the position above the test cylinder head, the sealing pressing head lifting device is started to enable the test sealing pressing head to be in contact with the cylinder head and block water through holes in the cylinder head, the pressure water feeding device is started to perform pressure water flushing in the cylinder head, the sealing property of the cylinder head is observed, and the operation is easy and saves labor.

Description

technical field [0001] The invention relates to a testing and testing equipment for a cylinder head of a locomotive, in particular to an automatic test bench for hydraulic sealing of a cylinder head of a locomotive. Background technique [0002] There are various types of locomotives, such as Dongfeng 8B, Dongfeng 4B, Dongfeng 12, etc. Although the models of locomotives are different, internal combustion engines are installed on various types of locomotives as power components, and cylinder heads are one of the important parts of internal combustion engines , In order to ensure the reliable operation of the internal combustion engine, a cooling water cavity is provided inside the cylinder head, and a cooling water inlet hole and a water passing hole connected with the cooling channel of the internal combustion engine and surrounding the outer circumference of the cylinder are provided on the cylinder head. It can be seen that the function of the cylinder head is to seal the ...

AI Technical Summary

Problems solved by technology

[0003] At present, the hydraulic sealing test method of the cylinder head is manual operation, which is cumbersome to operate, takes a long time to test, has low test efficiency, and is prone to safety accidents

In particular, the cylinder heads of diesel locomotives are bulky and all have cast iron structures, which require the cooperation of multiple people to complete. Therefore, it is necessary to further improve the current hydraulic sealing test equipment to avoid the above defects
