The invention discloses an anti-falling device for a perpendicular counterweight. The anti-falling device comprises two supporting structures which are oppositely arranged, wherein a fixed framework is connected on the supporting structures; two connecting shafts which are oppositely arranged are mounted on the fixed framework; the two ends of each connecting shaft connected to hook bodies throughtorsion springs; adjacent hook bodies on different connecting shafts are connected through a first connecting line; the two first connecting lines are connected by two second connecting lines; the second connecting lines are provided with an annular part in a penetrating mode; the two ends of the annular part separately are provided with third connecting lines in the penetrating mode; and one ends of the two third connecting lines are connected to speed difference anti-falling devices. The anti-falling device accomplishes locking of the counterweight while the counterweight has an accident, and has a higher success rate, so that the risk that lower floor is destroyed is avoided; a bored position above a conveyor counterweight device is utilized for mounting the anti-falling device; load on mounted floor is small in a working process, so that the anti-falling device is suitable for being additionally arranged on an existing model; and counterweight can be effectively prevented from laterally swinging to hit against a floor wall body.

The invention discloses a suspension steering device for a hub direct-driving electric vehicle and relates to the field of vehicle suspensions and steering mechanisms. The other end of a first vertical twisted part is connected with one end of a second vertical twisted part. The other end of the second vertical twisted part is fixedly connected with one end of a direction connecting rod which is fixedly arranged on the horizontal beam. A gyropendulum arm is arranged on the direction connecting rod. A gyroscope is arranged on the gyropendulum arm. Damper supports are arranged at the positions, close to a longitudinal suspending arm, of the outer sides of two longitudinal beams of a vehicle frame. An elastic damper is arranged on each damper support. One end of each elastic damper is fixed at the corresponding damper support. The other end of each elastic damper is fixed on the longitudinal suspending arm. The suspension steering device is reasonable in structure design, easy to operate and convenient to use, a large damping stroke can be provided, lateral swinging of wheels is avoided, abrasion of the wheels and a hanging mechanism is avoided, a plurality of groups of driving axles can be used on a vehicle chassis conveniently, a vehicle chasses structure is greatly simplified, and weight is lowered.

The invention discloses an airplane overturn testing device, which comprises a testing platform and supports which are used for supporting the testing platform. An airplane hinging joint is arranged at the front end of the upper surface of the testing platform. The nose of an overturned airplane is hinged with the airplane hinging joint. Stand columns are arranged on the two sides of the testing platform. Sliding wheels which are in contact with the fuselage of the airplane are arranged on the stand columns. An inertial load loading mechanism and a friction loading mechanism are additionally arranged. The invention additionally discloses an a airplane overturn testing method, which comprises the following steps of: arranging the testing platform, installing the airplane hinging joint on the testing platform for hinging the nose of the airplane; overturning the airplane, placing the overturned airplane on the testing platform and hinging the nose of the airplane with the airplane hinging joint; arranging the stand columns on the two sides of the fuselage of the airplane on the testing platform, installing the sliding wheels on the stand columns and enabling the installed sliding wheels to be in contact with the fuselage of the airplane; and arranging the inertial load loading mechanism and the friction loading mechanism. The airplane overturn testing device and the airplane overturn testing method have the advantages that the attitude of the overturned airplane is really simulated the accuracy of extrusion load at points wherein the overturned airplane is in contact with the group is guaranteed.
