EXAMPLE six

Referring to fig. 1, on the basis of any one of the first to fifth embodiments, further, the crack repairing apparatus further includes a heater 5 for heating the crack filler, the heater 5 is rotatably disposed on the carrier 1 and heats the crack filler, specifically, a rotating shaft may be disposed on the carrier 1, and the heater 5 is connected to the heating head. The heater 5 is arranged on the bearing frame 1, so that the distance between a heating head of the heater 5 and a crack to be repaired can be ensured to be constant, and the phenomenon that the repair object is damaged due to overhigh temperature or the repair efficiency is low due to overhigh temperature caused by overlong and overlong distance between the heater 5 and a crack filler when the filler liquid is directly heated by the heater 5 is avoided. The heater 5 can rotate relative to the bearing frame 1, and when the crack filler is used, a person rotates at the joint of the heater 5 and the bearing frame 1 according to requirements, so that the heating head is adjusted to ensure that the heating head can be aligned with the crack filler.

In the present embodiment, the heater 5 may be a hot air blower. In the crack repairing process, the hot air blower is started, so that the temperature inside the crack can be raised by the hot air blower, the filling liquid molecules are more active, and the filling liquid molecules are accelerated to permeate into all the gaps of the crack. Moreover, the hot air blown out by the hot air blower can change the air pressure above the crack, pressure difference is generated above and in the crack, the crack can be structurally changed to a certain extent, and the filling liquid can permeate into each crack along the track in the crack under the action of the air pressure. Therefore, under the combined action of heat and air pressure, the filling liquid can more quickly and more fully enter all corners inside the crack, and the crack filling effect is further improved.

EXAMPLE seven

On the basis of any one of the first embodiment to the sixth embodiment, the fracture repairing apparatus further includes an ultrasonic transmitter for transmitting ultrasonic waves to the fracture filler. Ultrasonic waves refer to sound waves with frequency higher than 20000 hertz, and have the advantages of good directivity, strong penetrability and the like. The type of ultrasonic transmitter is not limited, and may be selected from WL0-00, MD-KMD-K, etc.

In the process of filling the crack, the ultrasonic transmitter is started after filling liquid is injected into the crack, the filling liquid is guided into the crack to a certain extent by utilizing the extremely strong penetrating power and energy transmission capability of ultrasonic waves, and the filling liquid enters all corners in the crack at a higher speed; meanwhile, the transducer of the ultrasonic transmitter can generate certain heat, so that the ultrasonic transmitter has double functions, namely the combined action of ultrasonic waves and heat, enables molecular activities of filling liquid to be more active, and can enter cracks more quickly and fully. During the penetration of the filler fluid into the cracks, the filler fluid may generate tiny bubbles. When the ultrasonic transmitter transmits ultrasonic waves to filling liquid in the crack, the ultrasonic waves can also shock bubbles generated by the filling liquid, so that the bubbles inside the crack are reduced, the bubbles are prevented from being left behind after the crack is filled, and the attractiveness of a repaired product is influenced. And after the bubbles in the cracks are reduced, certain gaps are formed, and the filling liquid can be squeezed into the gaps, so that the cracks are filled more compactly, and the filling effect is further ensured.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
