Gap repairing and filling device for road construction

Abstract

The invention belongs to the technical field of road construction gap filling, and discloses a gap repairing and filling device for road construction, which comprises a cart, a push handle, a charging barrel, a feeding pipe, a motor, universal wheels, a discharging pipe and an electromagnetic valve; a air cylinder and a containing cylinder are fixedly installed on the left side of the bottom of the cart, the telescopic end of the air cylinder extends into the containing cylinder and is fixedly provided with a connecting block, two rotating columns are movably installed on the left side of the bottom of the cart through shaft sleeves, and a limiting cylinder is fixedly installed between the two rotating columns. The air cylinder is arranged and extends rightwards to drive the connecting block to move rightwards, so that a first spring is compressed, a guide column can drive the limiting cylinder and a bent column to rotate when encountering ground limiting in a road gap, the first spring is compressed, and therefore the flexible vertical force of the guide column is kept; and the self-protection performance is improved while stable guiding is conducted, and therefore obvious accurate filling of the discharging pipe can be achieved.

Description

technical field [0001] The invention belongs to the technical field of gap filling in road construction, in particular to a gap repairing and filling device for road construction. Background technique [0002] After long-term use of urban roads, due to thermal expansion and contraction and the rolling of passing vehicles, narrow and long cracks will appear on the road. If the filling and repairing is not carried out in time, the cracks in the road will further develop until the road is scrapped and cannot pass. Therefore, it is necessary to A gap repair filling device used in road construction, the inside of which is filled with asphalt, and then the asphalt is filled into the cracks to complete the repair. [0003] At present, for some straight cracks, it is generally not used to manually take out the material pipe to align the cracks, but directly align the discharge port with the bottom of the device and move it along the path of the cracks, and then fill and repair; but ...

Problems solved by technology

[0002] After long-term use of urban roads, due to thermal expansion and contraction and the rolling of passing vehicles, narrow and long cracks will appear on the road. If the filling and repairing is not carried out in time, the cracks in the road will further develop until the road is scrapped and cannot pass. Therefore, it is necessary to A gap repair filling device used in road construction, the inside of which is filled with asphalt, and then the asphalt is filled into the cracks to complete the repair

[0003] At present, for some straight cracks, it is generally not used to manually take out the material pipe to align the cracks, but directly align the discharge port with the bottom of the device and move it along the path of the cracks, and then fill and repair; but due to Lack of limit guide measures, even if it is a straight and narrow crack, manual pushing will still deviate the route, resulting in failure of filling and asphalt cannot accurately enter the crack; and the depth of each part of the crack is different, some are deep and some are shallow , but in the prior art, it is impossible to judge the depth of the crack and adjust the output accordingly, resulting in low filling efficiency; at the same time, in the prior art, the asphalt is left unattended after the filling operation is completed, and there is a lack of corresponding smoothing mechanism, Causes the asphalt to cool and solidify rapidly, resulting in uneven roads
