Description

Technical Field

[0001] This utility model relates to the technical field of curbstone processing equipment, and in particular to a high-efficiency grinding equipment for municipal road stone curbstones. Background Technology

[0002] In urban road construction, the installation and beveling of curb stones are crucial steps, affecting not only the aesthetics of the road but also significantly impacting traffic safety. The conventional method for installing and beveling stone curb stones involves: the curb stones are beveling and polished in the factory, then transported to the construction site for installation. However, dimensional deviations in the stone processing result in multiple material selections and adjustments during on-site installation. Furthermore, unsatisfactory straightness control leads to an unattractive appearance, frequently resulting in rework and low work efficiency.

[0003] Some existing curbstone grinding equipment can achieve on-site grinding of curbstones. Its technical feature is the combination of a trolley and a grinding device. The angle of the grinding device is pre-adjusted, and then the trolley carrying the grinding device is moved along the road where the curbstones are installed, while the grinding device is activated simultaneously, achieving grinding while moving. However, existing grinding devices often require applying pressure during grinding, and the pressure needs to be applied slowly depending on the grinding depth; otherwise, it easily accelerates the wear of the grinding machine. Therefore, the existing mobile grinding equipment's method of pre-adjusting the grinding device before pushing the trolley for grinding is not very efficient, and the grinding effect is not as good as expected. In addition, since adjacent curbstones are not completely flat after installation, pushing the trolley for grinding easily damages the grinding blades. The overall grinding effect is even worse than manually grinding before installation, and urgently needs improvement. Utility Model Content

[0004] To address the shortcomings of the aforementioned technologies, this utility model provides a high-efficiency grinding device for municipal road stone curbs, comprising an installation trolley with several moving wheels and an automatic grinding device. Each of the moving wheels is equipped with a braking mechanism. The automatic grinding device is mounted on the installation trolley and includes an electric grinding blade, a fixed mounting plate for mounting the grinding blade, a transverse mounting plate for lateral grinding blade movement, a lead screw slide guide rail for grinding blade movement, an oblique mounting plate for oblique grinding blade movement, a transverse drive cylinder, an oblique drive cylinder, and an adjustable mounting base. The transverse mounting plate is connected to the piston rod of the transverse drive cylinder and is mounted on the installation trolley. A guide rail for the screw slide is mounted on a horizontal mounting plate. The movable mounting seat is mounted on the slide of the guide rail. The inclined mounting plate is fixedly mounted on an adjustable mounting seat. The electric grinding blade is mounted on a fixed mounting plate. A pair of slide rods are provided on the fixed mounting plate. A mounting baffle is provided on the inclined mounting plate. A pair of through holes matching the slide rods are opened on the mounting baffle. The pair of slide rods are located in the pair of through holes. The ends of the pair of slide rods are provided with detachable retaining edges. A compression spring is fitted on the pair of slide rods. The inclined drive cylinder is mounted on the inclined mounting plate. A push plate is provided on the piston rod of the inclined drive cylinder. One end of the push plate contacts the ends of the pair of slide rods.

[0005] Using the above technical solution, the installation trolley is pushed to one side of the curbstone installed on the road. After the moving wheels are braked to stop the installation trolley and the adjustable mounting seat is adjusted, the automatic grinding device is started. At this time, the electric grinding blade is activated. The horizontal drive cylinder and the oblique drive cylinder work together to control the electric grinding blade to slowly advance and grind the edges and corners of the curbstone. At the same time, the lead screw slide guide rail controls the electric grinding blade to move back and forth along the direction of the guide rail until the edge and corner of the curbstone section with the same length as the guide rail is completed. Since the electric grinding blade advances slowly during the back and forth movement, the curbstone can be completely ground without damaging the grinding blade.

[0006] A further feature of this invention is that a pair of guide wheels are provided on the side of the installation trolley.

[0007] By adopting the above technical solution, since a pair of guide wheels are provided on the side of the installation trolley, the pair of guide wheels can be made to fit against the curb when the installation trolley moves, so that there is no need to deliberately control the forward direction of the trolley when pushing it.

[0008] A further feature of this invention is that the installation trolley is also equipped with a cleaning water tank, and a cleaning water pipe is connected to the cleaning water tank via a water pump. One end of the cleaning water pipe is equipped with a high-pressure nozzle, and the position of the high-pressure nozzle is aligned with the grinding blade.

[0009] By adopting the above technical solution, since the installation trolley is also equipped with a cleaning water tank, the cleaning water tank is connected to a cleaning water pipe via a water pump, and a high-pressure nozzle is provided at one end of the cleaning water pipe. The position of the high-pressure nozzle is aligned with the grinding blade, so when grinding the curbstone, water can be sprayed directly through the high-pressure nozzle to minimize dust.

[0010] A further feature of this invention is that a rubber pad is provided at the edge of the horizontal mounting plate.

[0011] By adopting the above technical solution, since a rubber pad is provided at the edge of the horizontal mounting plate, the horizontal movement of the grinding tool is made smoother by the buffering effect of the rubber pad. Attached Figure Description
