Problems solved by technology

[0003] After the bridge construction is completed, because the surface of the poured concrete is very rough during the pouring process, the road surface cannot meet the needs of people after solidification, so the road surface needs to be polished. The existing stone grinder for bridge construction has a single structure and a single function. , the area of ​​the grinding disc is fixed, so that each time it is rotated and polished, the grinding area is also certain. For bridges with different areas and different grinding needs, it cannot be adjusted, so it cannot meet the use requirements.

Abstract

The invention discloses a grinding-area-adjustable stone grinding machine for bridge construction. The grinding-area-adjustable stone grinding machine comprises a rack and a grinding unit, the grinding unit includes a grinding assembly and a lifting mechanism for driving the grinding assembly to ascend and descend, the grinding assembly includes a grinding rotation shaft, a first motor used for driving the grinding rotation shaft to rotate, and a grinding body fixedly mounted at the bottom end of the grinding rotation shaft, the grinding body comprises a millstone, an adjusting block, a connecting rod, a worm gear ring, and a worm, the lifting mechanism comprises an electric push rod, a first mounting plate, a second mounting plate, and a compression spring, and further includes a dust reduction unit and a cleaning unit. According to the grinding-area-adjustable stone grinding machine for bridge construction, the grinding assembly is arranged, the grinding diameter during grinding canbe adjusted to achieve the effect of adjusting the grinding area according to demand; the lifting mechanism is arranged and can protect the grinding body, and meanwhile the compression amount of the compression spring can be adjusted to achieve the purpose of adjusting the grinding amount; the dust reduction unit and the cleaning unit are arranged to avoid affecting the environment and the healthof workers, and debris is avoided from affecting the grinding quality and even damaging the grinding body.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a stone grinder with adjustable grinding area for bridge construction. Background technique [0002] Bridge construction is the process of building a bridge according to the design content; it mainly refers to bridge construction technology and construction organization, construction management, construction quality and other contents. [0003] After the bridge construction is completed, because the surface of the poured concrete is very rough during the pouring process, the road surface cannot meet the needs of people after solidification, so the road surface needs to be polished. The existing stone grinder for bridge construction has a single structure and a single function. , the area of ​​its grinding disc is all fixed, so that when each rotation is polished, the grinding area is also certain. For bridges with different areas and different grinding needs, it canno...
