The tire-type quick impact testing machine comprises an impact device, an accelerating device, a lifting device, a fixed ejection weight balance device, a buffering device and an impact testing platform; the impact device comprises a stepped shaft I, tires I and II, bearings I, a support guide rod and a straight spur gear I; the accelerating device comprises a speed variation device, a spline shaft, a slippage gear, a shifting fork device, a support I, a motor I, lower and upper box bodies, bearings II, III and IV, cone pulleysI and II, input shafts I and II, speed variation steel balls, stepped shafts II and III, bearing pedestals I and II, straight spur gears II, bevel gears I and II, an incomplete gear, a rocker, a speed variation connecting rod, a speed variation crank and a small motor; the lifting device comprises a crankshaft, connecting rods, telescopic rods and a motor II; the buffering device comprises buffering outer and inner shells, a spring I, balls and a buffering transparent cover; the fixed ejection weight balance device comprises a balancing weight, a fixed ejector and a support II. The tire-typequick impact testing machine has the advantages of being flexible and capable of achieving quick speed changing and lifting.

Description

technical field [0001] The invention relates to the field of impact testing machines, in particular to a tire impact and friction coating so as to detect the performance of the coating. Background technique [0002] At present, in the field of impact testing machines, there are shortcomings such as long acceleration and lifting time, and a large difference from the actual impact situation; in order to overcome these difficulties, the present invention provides a tire as an impact object, a speed change device and a gear as an acceleration device, Using the offset crank slider mechanism as the lifting device, using the trimming pin and the spring as the fixed ejection weight device, and using the spring as the buffer device, the device has fast acceleration, variable speed acceleration, and fast lifting to achieve better simulated aircraft landing. Beneficial effect on impact and friction action of floor coatings. Contents of the invention [0003] The problem to be solved...
