Description

Technical Field

[0001] The invention relates to the technical field of municipal road repair equipment, in particular to grouting equipment used for municipal highway repair. Background Art

[0002] Roads determine the speed of logistics. Developed and smooth logistics are the guarantee for rapid economic development. China's economy has experienced decades of development, with huge investment in basic roads. Damaged roads need to be repaired during use. When cracks appear on the road surface, the traditional method is to manually pour asphalt into it. Because the rigidity of asphalt is very low after heating, the cracks will be eroded by the tires when the vehicles pass by, causing the cracks to continue to grow, and the road surface needs to be fully filled.

[0003] Publication No. CN211446522U discloses a vertical grouting device for highway repair. By providing a feed barrel, under the joint action of a first spring, a column, a cover plate, a slide rod and a slip ring, the feed barrel can be forced to compress the first spring after reaching a set material volume, thereby allowing the column to push open the cover plate, so that the material inside the feed barrel is injected into the feed port along the discharge pipe, thereby achieving the purpose of quantitative feeding. By providing a proximity switch, when the feed barrel presses the proximity switch, the electromagnet is energized to generate magnetic force, causing the magnetic forces of four pairs of electromagnets to repel each other, thereby keeping the feed barrel in a downwardly pressed state, so that all the material inside the feed barrel can be discharged smoothly. However, this patent still has the following problems during actual use:

[0004] Although the vertical grouting equipment for highway repair is provided with a feed barrel, under the joint action of the first spring, the column, the cover plate, the slide rod and the slip ring, the feed barrel can be forced to compress the first spring after reaching the set material volume, so that the column can push open the cover plate, so that the material inside the feed barrel is injected into the inside of the feed port along the discharge pipe, thereby achieving the purpose of quantitative feeding, but when repairing the highway, for asphalt pavement cracks, different treatment methods are adopted according to the width of the cracks. For slight cracks with a width of less than two millimeters, asphalt can be sprayed on the surface and pressed in. For cracks with a width of more than two millimeters, modified asphalt can be poured in and coarse sand can be sprinkled on it for rolling. Therefore, the repair methods for cracks of different widths are different, and corresponding adjustments cannot be made according to the size of the cracks.

[0005] Therefore, a grouting device for municipal highway repair is proposed to solve the above-mentioned problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a grouting device for municipal highway repair, so as to solve the problem proposed in the above background technology that when repairing the highway, different treatment methods are adopted for asphalt pavement cracks according to the crack width.

The specific contents are as follows:

[0022] 1. By setting up a quantitative unloading mechanism, not only can the lifting motor be used to drive the lifting rotating rod and the bevel gear transmission assembly to rotate, so that the bevel gear transmission assembly drives the lifting threaded rod to rotate, and at the same time the lifting threaded sleeve drives the lifting plate to move up and down, when the ground crack is less than two millimeters, the bottom of the discharge nozzle can be inserted into the gap, and the discharge motor is started to drive the discharge auger to rotate.

[0023] 2. By setting up the cleaning and scraping mechanism, not only can the push handle be used to push the repair vehicle to move for the uninterrupted repair of road cracks, but before the road surface is repaired, the adjusting motor is started to drive the sprocket transmission assembly and the adjusting threaded rod to rotate, so that the adjusting threaded sleeve drives the dust suction bracket to move up and down, and the dust suction bracket is moved to the bottom of the road surface.

[0044] Working principle: Before using this grouting equipment for municipal highway repair, it is necessary to check the overall condition of the device to ensure that it can work normally.

[0045] Secondly, the lifting motor 102 is used to drive the lifting rotating rod 103 and the bevel gear transmission assembly 104 to rotate, so that the bevel gear transmission assembly 104 drives the lifting threaded rod 105 to rotate, and at the same time, the lifting threaded sleeve 106 drives the lifting plate 107 to move up and down. When the ground crack is less than two millimeters, the bottom of the discharge nozzle 114 can be inserted into the gap, and the discharge motor 111 is started to drive the discharge auger 112 to rotate. Through the structural characteristics of the discharge auger 112, the asphalt raw material can be transported, which is convenient for repairing the cracks in the road surface. At the same time, the heating ring 110 is used to heat the first discharge pipe 109 to avoid the asphalt raw material from cooling and solidifying, which causes the first discharge pipe 109 to be blocked. When the crack width of the road surface is greater than two millimeters, coarse sand needs to be sprinkled and modified asphalt is used to repair the road surface, thereby improving the efficiency and repair effect of the road surface repair. When the crack width of the road surface is greater than two millimeters, the measurement is performed. The feeder 128 will extend into the crack, and under the action of the support block 127, the second discharge pipe 125 drives the sliding plate 118 to descend, and under the action of the opening and closing rotating rod 122, the opening and closing sliding sleeve 120 slides on the outside of the opening and closing sliding rod 119. At the same time, the opening and closing sliding sleeve 120 drives the opening and closing baffle 124 to move relatively, which can open the bottom of the sliding plate 118, allowing the coarse sand to pass through the second cylinder 115 and the protective cylinder 123 into the second discharge pipe 125, and fall into the gap through the inclined nozzle 126 and the measuring feeder 128, thereby cooperating with asphalt to repair the road surface gap. By measuring the inclined surfaces on both sides of the feeder 128, it can adapt to cracks of different widths, thereby adjusting the expansion range of the opening and closing baffle 124, and can increase the amount of coarse sand discharge according to the width of the crack, thereby repairing the crack accordingly, improving the efficiency of crack repair, and at the same time repairing potholes on the road surface.

[0046] Finally, the repair vehicle 201 is pushed by the pushing handle 202 to facilitate the uninterrupted repair of the road cracks. At the same time, before the road surface is repaired, the adjusting motor 204 is started to drive the sprocket transmission component 205 and the adjusting threaded rod 206 to rotate, so that the adjusting threaded sleeve 207 drives the dust suction bracket 208 to move up and down, and the dust suction bracket 208 is moved to the bottom of the road surface. The rotating motor 210 is started to drive the cleaning roller 211 to rotate, which can clean the road surface. At the same time, the dust suction fan 221 is started to make the dust suction bracket 208 generate a certain suction force, which can The dust and garbage on the road are absorbed and collected by the collection tray 217 inside the vacuum cleaner 216. The dust and garbage can be filtered through the filter 220 to prevent the dust and garbage from colliding with the dust suction fan 221, thereby preventing the dust suction fan 221 from being damaged. The leveling bracket 212 and the flattening roller 214 are driven down by adjusting the threaded sleeve 207. The repaired cracks can be flattened by the flattening roller 214, and the leveling block 215 is used for secondary leveling, thereby improving the effect of crack repair.
