| titleOfInvention | Wheel-rail type roughening machine and roughening method for cement concrete surface |
| abstract | A wheel-rail type bush hammer and a cement concrete surface bush hammer method relate to the technical field of road and bridge engineering, and the wheel-rail type bush hammer comprises a bracket, a wheel rail and a bush hammer mechanism, wherein the bracket is provided with a roller, and the bush hammer mechanism is arranged on the bracket; the chiseling mechanism comprises a crankshaft, a hammer cutter and a locking and resetting mechanism, the hammer cutter is arranged on a connecting rod journal of the crankshaft, and the hammer cutter is driven to chisel a concrete surface when the crankshaft rotates; locking and canceling release mechanical system include locking round pin and arc wall, locking round pin and arc wall separately set up on the lateral wall of bent axle arm and the lateral wall of hammer sword, the tank bottom surface of arc wall is one by inclined plane or the cambered surface of going to back gradual uplift, tank bottom at the arc wall initiating terminal is equipped with a depressed part, the rear end of locking round pin supports and leans on an elastomeric element, will hammer sword locking in the locking round pin front end inserts the depressed part, locking round pin front end contacts and has at least a contact surface for domatic in the contact surface of the two with the lateral wall contact of depressed part. The wheel-rail type bush hammer is high in construction efficiency, deep in chiseling point and good in operation stability. |
