A rolling test bench and test method for a riding lawn mower

Abstract

The invention provides a riding type mower turning testing platform and a testing method. The riding type mower turning testing platform comprises a starting platform and a continuous turning platform device, wherein a continuous turning platform surface of the continuous turning platform device is moveably connected with a continuous turning platform base; a turning platform device of the starting platform is moveably connected with a lifting device and a starting platform base in sequence. The starting platform is pushed by a traction mechanism on the starting platform base, then the starting platform can easily approach to the continuous turning platform device, and butt joint of the continuous turning platform surface with the turning platform surface of the turning platform device is achieved; in addition, the included angle between the continuous turning platform surface and the turning platform surface with the horizontal plane can be adjusted according to testing requirements, so that turning testing of different heights can be achieved, and testing on a riding type mower turning protection device is completed; the equipment is simple in structure, convenient to operate, low in price, relatively high in reliability and intelligence, relatively stable in performance and high in equipment utilization rate; by adopting the testing method, testing on the riding type mower turning protection device can be completed.

Description

technical field [0001] The invention relates to the technical field of vehicle rollover tests, in particular to a rollover test bench and a test method for a ride-on lawn mower. Background technique [0002] As the use of ride-on lawn mowers becomes more and more common, the working environment of ride-on lawn mowers becomes more and more complex, and ride-on lawn mowers often need to work on slopes, which is prone to ride-on mowing The continuous rollover phenomenon of the machine may even cause casualties. In order to protect the life safety of the driver of the ride-on lawn mower and prevent the continuous rollover phenomenon of the ride-on lawn mower, it is necessary to investigate the safety performance of the ride-on lawn mower when dynamic rollover occurs, and conduct rollover tests with different slopes. [0003] At present, there are a large number of test vehicle rollover test benches on the market, which are used to conduct a large number of tests in the developm...

Problems solved by technology

[0003] At present, there are a large number of test vehicle rollover test benches on the market, which are used to conduct a large number of tests in the development process of cars and other vehicles to verify the safety performance of vehicles to meet the needs of different users. For example, the application number is CN201510137253.8 The invention patent discloses a vehicle rollover test bench, which can realize various rollover collision tests on vehicles, thereby improving the equipment utilization rate of the test bench, but the rollover of the vehicle on the vehicle rollover test bench is different from the actual ground rollover It is too large to simulate the process of the vehicle rolling on the ground, and the test data of the vehicle protection device when the vehicle rolls cannot be obtained accurately in time; another example, a Chinese patent No. ZL201420220800. Shorten the procedures in the process of scrapping cars, save time and improve production efficiency, but the structural stability of the lifting and tumbling platform is poor, and it is only suitable for small scrapped cars, especially when lifting and turning, because the center of gravity of the lifting and turning platform is raised , the stability is reduced, once it is squeezed, it is easy to cause damage to the transmission device, and the working life is short; for another example, the Chinese patent No. ZL201521086204.8 discloses a device for vehicle rollover testing. It is based on the chassis fixed on the ground, and the rolling mechanism connected to the chassis and used to carry the vehicle. The device has a simple structure and low cost, but it has poor stability when lifting and rolling, and cannot realize continuous rolling operation.

[0004] When these above-mentioned test vehicle rollover test benches are transferred to the ride-on lawn mower rollover test, on the one hand, each slope test in the ride-on lawn mower rollover test requires a specific test device and related auxiliary equipment, and the test cost is very high. On the other hand, the safety performance test process of these test vehicle rollover test benches for the ride-on lawn mower roll-over protection device (ROPS) is cumbersome, and cannot meet the requirements of the ride-on lawn mower continuous rollover test
