Emergency supporting mechanism capable of changing elastic deformation for concrete paver

Abstract

The invention discloses an emergency supporting mechanism capable of changing elastic deformation for a concrete paver. The emergency supporting mechanism structurally comprises flattening rollers, aspiral stirring device, supporting plates and driving systems. According to the emergency supporting mechanism, in order to improve the flattening quality and avoid the situation that due to unexpected stopping and half-stopping, a large area of marks are left on the material surface, through springs, swing rods and driving wheels which are provided by elastic components, traction force is generated by the driving wheels while the equipment is started, elasticity deformation of the springs occurs, under the condition of stopping of the paver or unexpected stopping, the traction force is gradually decreased, the springs are reset, thus the swing rods deform from a T-shaped structure into a Y-shaped structure to downwards push supporting steel frames, the equipment can be supported to be disengaged with the material surface accordingly, then residues of the large area of marks are reduced, and the flattening quality is improved.

Description

technical field [0001] The invention relates to a concrete paver accessory, in particular, an emergency support mechanism. Background technique [0002] In road construction, in order to ensure the smoothness of the road surface, the concrete mixture is paved with a paver. During the paving process, the traction force of the traction point is the resistance of the paver. If the paver runs at a uniform speed , the magnitude of the traction it receives will remain constant. If the paver stops midway or is forced to stop unexpectedly due to equipment failure, the spreading plate will stay on the material surface and leave marks, which are difficult to be compacted by the road roller, resulting in The overall quality of road surface roughness is reduced. Contents of the invention [0003] In view of this, the embodiment of the present invention provides an emergency support mechanism for concrete paver that can change the elastic deformation, so as to improve the paver stop m...
