Quick repair device for municipal road surface

Abstract

The invention discloses a quick repair device for municipal road surface, which comprises a car body and compacting rollers; symmetrical compacting rollers are arranged at the bottom of the car body; a mobile road breaking device is arranged between the compacting rollers; The middle position of the body is fixedly connected with an asphalt mixing tank; the middle position of the bottom of the asphalt mixing tank is connected with a discharge pipe, and the discharge pipe is provided with an electromagnetic valve. The present invention is equipped with a moving block driven by a hydraulic cylinder, so that the movement track of the cutting wheel and the breaking hammer is a rectangular surface movement, crushing the pits on the road surface, and avoiding damage to the road surface and roadbed at other positions; the present invention is equipped with asphalt mixing The heating device and the laying block are convenient for the on-site preparation and laying of asphalt, and the operation efficiency is high; the invention is equipped with a compacting roller and a digging hopper, and the digging hopper is convenient for cleaning the debris, and the compacting roller compacts the paved asphalt. Various, short operation cycle, suitable for repairing small road damage, cost-effective.

Description

technical field [0001] The invention relates to the field of municipal machinery, in particular to a rapid repair device for municipal road surfaces. Background technique [0002] Under the action of driving, the potholes caused by the partial loss of pavement aggregates need to be repaired; the traditional method of repairing pavement pits is manual repair. With the advancement of technology, there have been mechanical devices for pavement repair, including asphalt Stirring and heating devices, asphalt laying devices, road rollers, etc., use many mechanical devices, the operation is cumbersome, and the construction period is long. For some small pits, it is very uneconomical to use these large machines, and it is not suitable for some small road pits. The pits are repaired, resulting in waste of resources and high maintenance costs. [0003] There is a need for a small pavement patching device integrating multiple functions, which is easy to operate and low in use cost. ...
