Embodiment 1

[0033] The invention provides a dynamic and static dual-mode conversion test bench, such as Figure 1-4 As shown, it includes a base plate 1 , load wheels 2 and suspension rings 3 . Load-bearing wheels 2 are detachably mounted on the base plate 1 for moving the base plate 1, and the suspension rings 3 are connected through mounting holes opened on the base plate 1 to cooperate with lifting equipment to lift the base plate 1. In the present invention, through the cooperation between the two components of the load-bearing wheel and the suspension ring and the base plate, the base plate used to carry the experimental equipment does not need to dismantle the experimental equipment located on the base plate when the base plate used to carry the experimental equipment performs dynamic and static mode conversion, which is simple and convenient, and improves the practicability.

[0034] The substrate 1 is preferably made of stainless steel or high-quality carbon steel, which has good ...

Embodiment 2

[0038] This embodiment 2 is an operation method of a dynamic and static dual mode conversion test bench formed on the basis of embodiment 1. The dynamic and static dual mode conversion test bench of embodiment 1 is adopted, such as Figure 1-4 shown, including the following steps:

[0039] Assembly steps: install the suspension ring 3 and the shock absorber 6 on the base plate 1, and install the experimental equipment at a preset position on the base plate 1;

[0040] Moving steps: install the load-bearing wheels 2 on the base plate 1, and move the test bench carrying the experimental equipment to the corresponding position through the load-bearing wheels 2. When in the moving mode, the load-bearing wheels 2 are universal wheels, which can more conveniently carry the experimental equipment and move to places where driving or forklifts cannot travel, increasing the convenience of the experiment.

[0041] Static step: move to the test bench at the preset position, use the lifting...

Abstract

The invention relates to a dynamic and static dual-mode conversion experiment table and a use method thereof in the technical field of experiment racks. The experiment table comprises a base plate, bearing wheels and hanging rings; fixing holes are formed in the base plate, the multiple fixing holes are symmetrically distributed in the base plate, inserting blocks are connected to the bottom face of the base plate, the multiple inserting blocks are symmetrically distributed on the side face of the base plate, and inserting grooves are formed in the inserting blocks; and each bearing wheel comprises a wheel, a supporting leg and a connecting plate, one end of each supporting leg is rotationally connected with the wheel, the other end of each supporting leg is connected with the connecting plate, the connecting plates are detachably inserted into the inserting grooves, and the hanging rings are fixedly connected with the base plate through the fixing holes. According to the dynamic and static dual-mode conversion experiment table provided by the invention, when a moving mode is switched to a static mode, experiment equipment on the base plate does not need to be disassembled, and only a crane or a forklift needs to be used for hoisting a dynamic and static dual-mode conversion experiment table frame, plugging block bolts are disassembled from the inserting blocks, the bearing wheels are taken out from the side surface; and the dynamic and static dual-mode conversion experiment table is put down. The dynamic and static dual-mode conversion experiment table is simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to the field of engine test benches, in particular to the fields where conveniently moving experimental equipment and shock absorption are required, and in particular to the field of test benches used as bases for motors, gasoline engines and diesel engines. Background technique [0002] In engine experiments, it is often necessary to move experimental equipment to meet different experimental requirements, and engine experimental equipment, such as motors, gasoline engines, and diesel engines, can weigh hundreds of kilograms and is difficult to carry. At the same time, these experimental equipment are high-speed rotating parts, and the vibration generated during operation is likely to affect the normal operation of other equipment in the test site and the accuracy of the experimental test. For example, the vibration generated by the high-speed rotation of the motor may affect the measurement of the sensor. Diesel engine The vibrat...
