[0002] At present, with the rapid development of national transportation infrastructure, road construction will be standardized, mechanized and refined. In the construction of highways and urban roads, curbstones are widely used in road engineering. Roads with curbstones are an important component. Curbs can buffer and protect vehicles, reduce the occurrence of traffic accidents, and prevent mud, sewage and other damage to the road surface and facilities. However, during the installation process, because the curbstone is made of concrete and its weight is heavy, it is not only inefficient to use workers to carry it manually, but also easy to damage the curbstone, which not only affects the quality of the curbstone, but also increases the construction cost. Therefore, in order to facilitate the transportation and installation of curbstones, people have invented curbstone installation vehicles, such as Chinese Patent: A curbstone installation trolley, Application No.: 201921062641.4, Application Date: 2019.07.08, Abstract: The utility model discloses a curbstone installation trolley, including a base, a lever and a clamping assembly, wherein the lever is hinged to the upper part of the base, and the clamping assembly is arranged at one end of the lever close to the base; the base is a triangular structure, and wheels are arranged at both ends of the bottom thereof. The clamping assembly includes two clamping arms, a tray and a rope. The middle parts of the two clamping arms are provided with a plurality of through holes along the length direction. The two clamping arms are hinged together by a pin shaft passing through the through hole, so that the two clamping arms form a cross-symmetrical structure. The lower ends of the two clamping arms are respectively provided with a bending portion, and the two bending portions are symmetrically arranged facing each other for clamping the curb. The upper ends of the two clamping arms are respectively connected to the two ends of the tray through the rope, and the tray is fixedly connected to one end of the lever close to the base. The device has a simple structure and is easy to operate, and can improve the efficiency and quality of curb construction.
