Description

Anti-tipping vehicle stability test device

Technical Field

The application relates to the technical field of forklifts, in particular to anti-tipping vehicle stability testing device.

Background

The goods carried by the forklift are generally large in volume and heavy in weight, and the forklift is often used for driving or loading and unloading the goods on uneven roads. Therefore, in order to ensure the safety and stability of the forklift in use under normal working conditions, the forklift must have sufficient stability, the stability test needs to be carried out on the forklift before the forklift leaves a factory, the forklift is generally driven into a test platform in a horizontal state, and one side of the test platform can be inclined; the test platform is then gradually tilted to the standard specified tilt angle and if the truck passes through the full tilt condition and does not tip over, its stability is deemed acceptable.

When the forklift carries out stability test, when the limiting value that it took place to overturn is tested, can increase inclination continuously, so along with the increase of test platform inclination, the forklift has the possibility of overturning, so need hold the automobile body with the rope through many experimenters, prevent that the vehicle from overturning. There are two problems with this approach: once the test personnel can not hold the tilted car body, the car can be tilted and damaged, and the test personnel can fall and be injured; and two, the participation of a plurality of testers is required, so that the test efficiency is reduced.

The following description of the embodiments of the present application is provided by way of specific examples, and other advantages and effects of the present application will be readily apparent to those skilled in the art from the disclosure herein. The present application is capable of other and different embodiments and its several details are capable of modifications and variations in various respects, all without departing from the spirit of the present application. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

Referring to fig. 1-4, the utility model provides a vehicle stability test device that prevents toppling, including test platform 1, test platform 1's one end has set firmly support frame 4, install on support frame 4 and accomodate ware 3, the one end winding of rope 2 is on accomodating ware 3, the other end is connected with experimental vehicle. When the test vehicle is in the process of rollover test and reaches the limit angle, the rope 2 provides tension, the possibility that the vehicle can not rollover under protection is avoided, manpower is saved, efficiency is improved, and safety risk is reduced.

The test platform 1 is conventional, and the upper surface of the test platform is a bearing surface for supporting a test vehicle; the bearing surface is generally a plane and has certain friction force so as to prevent the test vehicle from sliding on the bearing surface when the bearing surface is inclined and the inclination angle is within the test angle range. The support frame 4 is arranged on the inclined rising side of the test platform 1 and used for applying pulling force to the test vehicle so as to prevent the test vehicle from overturning to the lower side of the test platform 1.
