Description

Technical Field

[0001] The utility model relates to a road damage repair device and belongs to the field of road repair. Background Art

[0002] Under long-term use and traffic pressure, uneven pedals will cause depressions on the road surface, which will continue to increase until an obvious "pit" is formed. Water accumulation and frequent vehicle traffic will make this problem more serious, and in severe cases, it will affect the fit between the wheels and the road surface, causing traffic accidents.

[0003] There is a technology now that injects a foam called polyurethane into the bottom of the road. After the foam expands and hardens, the road surface can be used normally.

[0004] The repair device currently used is to insert the injection head into the crack of the road, and then the damaged road can be filled inside; but when a depression is formed under the road, the road surface is sometimes not broken, so it is necessary to drill a hole on the road before the road can be repaired and filled; the existing equipment relies on drilling the hole, and then inserting the injection gun head into the hole for injection, which has many working steps and needs to be improved.

[0005] The Chinese invention patent with application number CN202111562217.8 provides a device and method for repairing and treating soft saturated soil roadbed subsidence of highways; the patent improves the repair equipment, but the applicant believes that the equipment is still relatively complex and has a high production cost; therefore, a new repair device is proposed to reduce costs. Utility Model Content

[0007] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0008] A movable frame is provided with a syringe rotatably mounted on the movable frame, an outer wall of the syringe is provided with an external thread, and the external thread is threadedly connected to the movable frame; the lower end of the syringe is provided with a tip, and a plurality of through holes are evenly distributed on the circumference of the tip.

[0009] Further: a first bevel gear is arranged outside the injection barrel, an internal thread matching the external thread is arranged inside the first bevel gear, and the first bevel gear is rotatably mounted on the movable frame.

[0010] Further: the first bevel gear is meshed with a second bevel gear, the second bevel gear is key-connected with a transmission shaft, one end of the transmission shaft is connected with a motor, and the motor is fixed on the moving frame.

[0011] Further: the movable frame includes a vertical frame and a horizontal frame arranged at the upper end of the vertical frame, and the motor is fixed on the horizontal frame.
