Pavement distress repairing machine

Abstract

The invention discloses a pavement distress repairing machine, and relates to the field of manufacturing of road maintenance engineering machinery. The pavement distress repairing machine consists of a locomotive, a chassis, a hydraulic pump, a fixing frame, a drill body and a driving motor, wherein the fixing frame stands on the main unit chassis of the locomotive and has a frame type structure; a drill body seat of the drill body is arranged on the fixing frame; two ends of the drill body seat are arranged on the outer side of the fixing frame and are hinged with a drill body lifting oil cylinder fixed on the main unit chassis; the drill body driving motor is fixed on the drill body seat and is connected with the drill body in a driving manner; and a working through hole of the drill body is formed in the main unit chassis. The pavement distress repairing machine is reasonable in structural design, stable in performance, high in maintenance efficiency and high in working efficiency and can work in different regions; the maintenance cost and the labor intensity of workers are reduced; materials are saved; the pavement distress repairing machine is convenient to maintain and then saves energy; particularly, when a pavement is repaired by using the pavement distress repairing machine, impact is not needed, and pressing drilling can be directly executed; a working procedure is reduced; cracks are not produced on the hole wall of a base layer; and the maintenance quality is guaranteed.

Description

technical field [0001] The invention relates to the manufacturing field of road maintenance engineering machinery, in particular to a road surface damage repairing machine. Background technique [0002] Highway pavement is often seriously damaged due to vehicle overloading and other reasons, especially in the northeast of my country, where the temperature difference between winter and summer reaches more than 50°C, and the pavement is more easily damaged, which requires regular maintenance of pavement gaps. When the road surface is damaged, timely repair is carried out. The usual road surface repair is just to pave a layer of asphalt or cement on the damaged road surface, but it cannot solve the problem of subgrade collapse, and the road surface after maintenance will be damaged again after a short time. If roadbed maintenance is done, it will take several weeks. If the maintenance time is too long, it will affect the traffic. At present, the road maintenance equipment on the...

[0002] Highway pavement is often seriously damaged due to vehicle overloading and other reasons, especially in the northeast of my country, where the temperature difference between winter and summer reaches more than 50°C, and the pavement is more easily damaged, which requires regular maintenance of pavement gaps. When the road surface is damaged, timely repair is carried out. The usual road surface repair is just to pave a layer of asphalt or cement on the damaged road surface, but it cannot solve the problem of subgrade collapse, and the road surface after maintenance will be damaged again after a short time. Several weeks if subgrade maintenance

If the maintenance time is too long, it will affect the traffic. Currently, the road maintenance equipment on the market has a single chiseling function, which cannot fundamentally repair the road surface.

The road surface damage rapid repair machine with the patent No. "201120453547.9" can maintain the roadbed, but in the repair procedure, it is necessary to impact the roadbed first, and then press the roadbed to complete the construction, but the damage to the damaged road surface during the impact The repair effect is not ideal and the work efficiency is low. The main performance is that the steel wire is used to lift the drill body. The impact force is large, and cracks appear around the hole, which is easy to irrigate and leaves hidden dangers to the roadbed.
