Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of highway engineering, and particularly relates to a highway crack repairing device. BACKGROUND

[0002] When a highway is used for a long time, internal materials of the highway are affected by external environmental factors and appear aging phenomenon, which causes the hardness of the road surface to decrease. When the pressure borne by the road surface is too large, cracks appear on the surface of the highway. The cracks not only affect the overall appearance of the road surface, but also cause the internal structure to rust and corrode, shorten the service life of the highway and increase the safety hazard.

[0003] In order to reduce the influence of the highway cracks and maintain the loss within a controllable range, a related device needs to be used to repair the cracks in time when the cracks are found. In the prior art, the device for repairing the highway cracks includes a cart, a storage tank fixed on the cart, and a spray gun connected with the storage tank. When repairing the highway cracks, an operator pushes the cart to the crack area and completes the repair of the cracks by holding the spray gun. During this period, the material in the storage tank is sent to the cracks under the action of the spray gun, and after the material solidifies, the cracks can be effectively filled and the influence caused by the cracks can be eliminated.

[0004] The inventor finds that the material for repairing the highway cracks usually refers to asphalt concrete, which has poor fluidity. During the process of injecting the material into the cracks, a gap is easily formed between the material and the bottom of the cracks.

[0050] Please refer to Figures 1 to 8 , now the highway crack repairing device provided by the present application will be described. The highway crack repairing device provided by the present application comprises a trolley 1, a translational member 2 and a lifting member 3.

[0051] The trolley 1 is used to support and move on the road surface, and has a gap between the bottom surface of the trolley 1 and the road surface during the movement.

[0052] In the embodiment, the trolley 1 is provided with a storage tank 4 fixed thereto for storing materials (generally referring to asphalt concrete), and the bottom of the storage tank 4 is connected with a feeding pipe 41; in actual use, the materials in the storage tank 4 will fall into the feeding pipe 41 under the influence of gravity.

[0054] In actual use, the translator 2 can be driven by the reciprocating driving member 5 to move a certain distance in the width direction of the trolley 1, so that the spray gun 8 can accurately aim at the road crack; at the same time, the translator 2 can be driven by the reciprocating driving member 5 to reciprocate in the width direction of the trolley 1, so as to increase the operation range of the spray gun 8 and ensure that it can adapt to ground cracks of different widths.

[0056] In the embodiment, the operator pushes the trolley 1 to one end of the road crack, and then moves the translator 2 to the upper side of the crack by the reciprocating driving member 5, so as to complete the preparation work. Then, the spray gun 8 is turned on, and the materials in the storage tank 4 can be sprayed into the crack; at the same time, the operator pushes the trolley 1 along the length direction of the road crack, and turns on the longitudinal driving member 6 to compact the materials in the crack. The above steps are repeated to complete the repair of the road crack and avoid the generation of cavities.

[0057] In the above process, the reciprocating movement of the translator 2 driven by the reciprocating driving member 5 can increase the material spraying range of the spray gun 8 to adapt to road cracks of different widths.

[0058] Compared with the prior art, the road crack repair device provided by the embodiment can provide pressure acting on the materials in time during the repair of the crack, so that the materials can be filled in the crack to avoid the generation of cavities and ensure the repair effect of the road crack.

[0071] By adopting the technical scheme, in actual use, since the transmission nut 521 cannot rotate relative to the cart 1, when the first rotating motor 511 drives the drive screw 51 to rotate, the transmission nut 521 can drive the transmission plate 52 to move along the axial direction of the drive screw 51; correspondingly, when the first rotating motor 511 drives the drive screw 51 to rotate reversely, the transmission plate 52 moves reversely.

[0072] In some embodiments, as shown in Figure 4 The transmission plate 52 has a positioning hole 522 penetrating in the up-down direction, and the translating member 2 has a counterposition hole 21 penetrating in the up-down direction and adapted to communicate with the positioning hole 522.

[0078] In actual use, the main shaft 42 is driven to rotate by the second rotating motor 422, so that the plurality of stirring arms 421 simultaneously swing, so as to avoid the solidification of the materials in the storage tank 4.

[0079] In some embodiments, as shown in Figure 1 and Figure 6 The upper side of the cart 1 is fixedly connected with a wire binder 7 connected with the feeding pipe 41, and the connection between the wire binder 7 and the feeding pipe 41 is located between the storage tank 4 and the translating member 2, so as to limit the movement track of the middle part of the feeding pipe 41 and avoid the intervention of the feeding pipe 41 to the use of other components.
