Problems solved by technology

[0002] When the car is exported to the EU countries, it must meet the requirements of the EU's relevant directives on cars. The metal fuel tank must be turned over to detect its oil leakage. The directive requires that the detection of the metal fuel tank needs to be turned over 90 degrees and kept for more than 5 minutes to measure its drip. The volume of the liquid is used as the judgment standard. There is no specific method of turning over the fuel tank and filling method. In practice, when this test is completed, the fuel tank is lifted by a truss truck, and then the turning force is artificially applied to make the fuel tank go smoothly. Overturning, when using a truss truck, only a single fuel tank can be turned over at a time, which is laborious, inconvenient, and inefficient. When filling, the mass of the solution is weighed by weighing method, and then added to the fuel tank. cumbersome and time wasting

Embodiment 1

[0019] Below in conjunction with accompanying drawing, describe in further detail:

[0020] Such as figure 1 Shown is a schematic diagram of an overturning platform for gear transmission power used for tank overturning tests, including an overturning platform bracket 1, an overturning platform 2, and an asynchronous motor 3. The overturning platform 2 is connected to the overturning platform bracket 1 with a bearing 5, and the asynchronous The motor 3 is fixed on the turning platform 2, the output shaft of the asynchronous motor 3 is fixed to a driving gear 4.2, and the short shafts on both sides of the turning platform 2 are splined to fix a driven gear for transmission to make the turning platform turn over 6.2, the driving gear 4.2 and the driven gear 6.2 mesh with each other to form a gear transmission mechanism. The control cabinet 7 used to control the asynchronous motor 3 is provided on the overturning table support 1. The control cabinet 7 includes an electrical box ...

Embodiment 2

[0029] Below in conjunction with accompanying drawing, describe in further detail:

[0030] Such as image 3 What is shown is an inversion bench used for the inversion test of the fuel tank. The gear transmission mechanism in the first embodiment is replaced with a belt transmission mechanism, and a spline is fixed on the short shafts on both sides of the inversion platform 2 for transmission. The driven pulley 6.1 that makes the turning platform turn over, the driving pulley 4.1 and the driven pulley 6.1 are connected by a transmission belt to form a transmission mechanism to drive the turning platform 2 to turn over. In this embodiment, a 1.5kw AC asynchronous motor 3 is selected as the turning platform support The power source of 1, under the control of the frequency converter in the control cabinet 7, the speed of the asynchronous motor 4 is controlled according to the needs, and the power is transmitted to the driven pulley 6.1 through the belt transmission mechanism t...

Embodiment 3

[0033]Below in conjunction with accompanying drawing, describe in further detail:

[0034] Such as Figure 5 Shown is a kind of inversion stand used for fuel tank inversion test, including inversion platform support 1, inversion platform 2, worm gear reducer 14 and asynchronous motor 3, inversion platform 2 is connected on inversion platform support 1 with bearing 5, Fix the worm gear reducer 14 on the overturning table support 1 with bolts, the output shaft of the asynchronous motor 3 is connected with the input shaft of the worm gear reducer 14 through the bushing, and the short shafts on both sides of the overturning platform 2 are fixed with splines One is used to drive the turning gear 6 that turns the turning platform overturned. The output shaft gear 4 of the worm gear reducer 14 is fixed on the output shaft of the worm gear reducer 14 and meshes with the turning gear 6. The turning platform support 1 is provided with a The control cabinet 7 that controls the async...

Abstract

The invention provides an overturning bench used for an overturning test of an oil tank. The overturning bench comprises an overturning platform bracket, an overturning platform, an asynchronous motor and a worm and gear decelerator, wherein the overturning platform is arranged on the overturning platform bracket, the decelerator is fixedly arranged on the overturning platform bracket, an input shaft of the decelerator is connected with an output shaft of the asynchronous motor, a shaft of the overturning platform is provided with an overturning gear used for driving the overturning platform to overturn, and an output shaft gear of the decelerator is meshed with the overturning gear. The invention also provides a test method for the overturning test of the oil tank by using the overturning bench, the rotation speed of the asynchronous motor is controlled by a frequency changer in a control cabinet according to needs, the overturning of the oil tank can be automatically controlled, and a self-lock hold state can be realized and the test is carried out when the oil tank is overturned to a special position, so that the time and the labor are saved, the overturning test efficiency of the oil tank is greatly improved.
