The invention relates to the technical field of construction machinery, in particular to a device for increasing wheel type construction machinery adhesive force. The device comprises a wheel type construction machinery body which is provided with a left support, a right support, a third drive axle, a left adhesive force increasing wheel and a right adhesive force increasing wheel. The left adhesive force increasing wheel and the right adhesive force increasing wheel are both of a cylindrical structure, the circular outer surfaces of the left adhesive force increasing wheel and the right adhesive force increasing wheel are each provided with conical teeth, the wheel type construction machinery body further comprises a rear drive axle which is provided with an input shaft, the other side of the rear drive axle is provided with power output shafts which are symmetrically arranged, an axle disengaging mechanism is arranged between the output shafts and the input shaft of the rear drive axle, and the output shafts of the rear drive axle are connected with input shafts of the third drive axle through telescopic universal drive shafts. By means of the device, the adhesive force can be increased in wheel type construction machinery traction operation, and the maneuvering characteristics of the wheel type construction machinery are not affected simultaneously, so that the problem that the wheel type construction machinery is prone to slipping when the traction operation is conducted on the soft and muddy ground is solved.
