However, before performing the engine test with the dynamometer, it is possible to perform the engine dynamometer test after checking the starting state of the engine and verifying the state of the engine, but conventionally, these operations were performed in a limited space such as an engine test room. There was an irrationality to remove the engine that failed the decision and take it out to the outside.

In addition, even if a normal engine is installed and an engine test is carried out, a long time installation work is required in a laboratory, and when a failing engine is installed, an installation and removal work is required, and an engine dynamometer is installed until the next test object is installed. Is left in an unused state, and there is a problem that the test linkage of the laboratory is deteriorated by this cause.

Therefore, in recent years, a mobile truck (Korean Utility Model Registration No. 228695) of a test engine was developed. Looking at the configuration thereof based on FIG. 1, the first engine support 2 for mounting the engine 1 and an engine dynamometer Connecting the upper guide rail (8) and the guide rail (8) installed to maintain the degree of freedom of the second engine support (3) supporting the connecting device of the adjustable height at the bottom The first (4) and the second (5) frame (Frame) installed with the moving wheel 17, the fastening for connecting other fluids such as fuel, cooling water, oil, back pressure measurement, exhaust gas measurement of the engine (1) The plate (Auto Docking Block) 2 (10) and the fixed rail (13), the fastening plate clamp (Auto Docking Block Clamping) (12) of the auto docking block 1 (9), 2 (10) Rotating wheel handle 18, which prevents the coupling and flow, is easy to run on one side of the body, the center of the engine There is a height adjustment device (6) to move up and down, left and right, and there is a center axis alignment device using the laser equipment (14) to record the values in the up, down, left and right directions to help the center axis alignment of the engine. Adjustable cam wheels 17 are mounted.

However, the conventional trolley can save a lot of time because it has the advantage of moving to the laboratory after installing the engine mounting and peripheral devices without being restricted by the place, although the engine specifications are different depending on the vehicle The upper guide rail 8, the first engine support 2 and the second engine support 3 are fixedly installed on the first and second pedestals 4 and 5, according to the size of the engine. Of course, there must be a problem in that a large amount of money is required to purchase various mobile loans, as well as a mobile loan having a size corresponding to the size.

Therefore, the present invention was created in view of the above problems. After installing the sliders that slide along the lower rail of the moving trolley, the upper guide rail on which the engine is mounted, the first engine support and the second engine support are installed on the slider, and the engines of various sizes are provided in one moving trolley. The purpose of the present invention is to provide a mobile truck for a test engine that can reduce the hassle of having to own a mobile truck according to each standard and can greatly reduce the purchase cost of the mobile truck.
