Abstract
Description
Technical Field
[0001] This application relates to the field of road repair, and in particular to an asphalt road repair device. Background Technology
[0002] Asphalt pavement cracks are one of the major pavement defects. If cracks are not repaired and treated in time, surface water will seep into the pavement base, causing the base to soften and its strength to decrease. With repeated vehicle rolling, the pavement will quickly break down, affecting traffic and increasing maintenance costs.
[0003] When existing asphalt pavement repair devices inject asphalt into cracks, the viscosity of the asphalt gradually increases during the injection process, and the asphalt nozzle is usually a fixed structure that cannot be adjusted. As a result, the asphalt cannot fill the cracks completely, thus reducing the repair effect on the asphalt pavement.
[0004] Regarding the aforementioned technologies, the inventors believe that existing asphalt pavement repair devices have the problem of failing to fill cracks, thus reducing the repair effect on asphalt pavements. Utility Model Content
[0005] To address the aforementioned technical problems, this application provides an asphalt pavement repair device.

[0008] By adopting the above technical solution, the heating pipe heats the asphalt in the storage tank, and the first motor drives the stirring shaft and stirring blades to rotate, thereby stirring the asphalt and keeping it highly fluid. The conveying mechanism delivers the asphalt into the discharge pipe, and the position of the discharge head is adjusted by the adjusting mechanism so that the discharge head can be aligned with the road surface cracks, thereby filling the cracks with asphalt and improving the repair effect of the asphalt pavement.
[0009] Preferably, the conveying mechanism includes a screw conveyor communicating with the storage tank, and one end of the screw conveyor away from the storage tank is connected to the discharge pipe.
[0010] By adopting the above technical solution, the screw conveyor transports asphalt, thereby reducing the phenomenon of poor asphalt discharge and improving the repair effect of asphalt pavement.
[0011] Preferably, the outer side of the screw conveyor is provided with a heat insulation layer.
[0012] By adopting the above technical solution, the insulation layer keeps the asphalt in the screw conveyor warm, thereby reducing the phenomenon of rapid temperature drop of asphalt leading to increased viscosity and improving the smoothness of asphalt discharge.
[0013] Preferably, the discharge pipe is a corrugated steel pipe.
[0014] By adopting the above technical solution, the corrugated steel pipe can drive the discharge head to rotate flexibly and rise and fall, thereby facilitating the adjustment of the position of the discharge head.
[0015] Preferably, the adjustment mechanism includes a mounting frame disposed on the mobile vehicle, an electric telescopic rod connected to the mounting frame, and a connecting ring disposed on the discharge head, wherein the connecting ring is connected to the end of the electric telescopic rod away from the mounting frame.
[0016] By adopting the above technical solution, the electric telescopic rod drives the connecting ring to rise and fall, thereby adjusting the height of the discharge head.
[0017] Preferably, a second motor is provided at the end of the electric telescopic rod away from the mounting frame, and the drive shaft of the second motor is fixedly connected to the connecting ring.
[0018] By adopting the above technical solution, the second motor drives the discharge head to rotate, so that the discharge head faces the cracks on the road surface, thereby improving the repair effect of the road surface cracks.
[0019] Preferably, the storage bin has a guide slope at one end near the screw conveyor, and a support rod is provided on the storage bin, the support rod being connected to the mobile vehicle.
[0020] By adopting the above technical solution, the guide slope guides the asphalt in the storage tank, thereby allowing the asphalt to flow into the screw conveyor, thus improving the smoothness of asphalt transportation.
[0021] Preferably, the end of the storage tank away from the screw conveyor is fixedly connected to a feed pipe, and a cover plate is detachably installed on the feed pipe.
[0022] By adopting the above technical solution, after the material is added to the storage tank, the cover plate is placed on the feed pipe, thereby reducing the heat loss in the storage tank and helping the asphalt maintain a high fluidity.
[0023] In summary, this application has the following beneficial technical effects:
[0024] 1. This application uses a heating mechanism and a mixing mechanism to maintain the high fluidity of the asphalt, and uses a screw conveyor to transport the asphalt, thereby improving the smoothness of asphalt transportation and making it easier for the asphalt to fill the cracks in the road surface;
[0025] 2. This application uses an electric telescopic rod and a second motor to adjust the height and angle of the discharge head, which helps the discharge head to face the road surface cracks, thereby facilitating the asphalt to fill the road surface cracks and improving the repair effect on road surface cracks.
