Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of floor grinding machines, and in particular to a concrete floor grinding machine. Background Technology
[0002] With the rapid development of the construction industry, concrete floors are widely used in industrial plants, commercial spaces, public facilities, and residential buildings due to their high strength, durability, and good load-bearing capacity. However, newly poured concrete floors often have rough and uneven surfaces, with defects such as laitance, sand, and cracks, which not only affect aesthetics but may also reduce the service life and safety of the floor. Therefore, it is necessary to grind concrete floors to remove surface defects and improve the flatness and gloss of the floor.
[0003] Currently, in existing grinding equipment, each grinding mechanism is equipped with a set of hydraulic cylinders at its upper end. Multiple grinding mechanisms rise individually, making individual replacement extremely inconvenient. Furthermore, due to the large size of the equipment when unfolded, large transport trucks are required for transportation, increasing resource waste. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a concrete floor grinder that reduces energy consumption by using multiple power sources for three sets of supports. One set of supports can be quickly disassembled through a support device, thereby facilitating the reduction of the overall width of the grinder, making it easier to transport using a small truck, and improving the ease of use.
[0005] This utility model discloses a concrete floor grinding machine, comprising a base and three sets of supports, the three sets of supports being circumferentially arranged on the base; it also includes a support device, three sets of support platforms, three sets of first motors, and three sets of grinding wheels. The support device is mounted on the base, and the three sets of supports are rotatably mounted on the base via the support device. One set of supports can be quickly assembled and disassembled via the support device. The three sets of support platforms are respectively mounted on the front ends of the three sets of supports, the three sets of first motors are respectively mounted on the top ends of the three sets of support platforms, and the three sets of grinding wheels are respectively rotatably mounted on the bottom ends of the three sets of support platforms. The output ends of the three sets of first motors are respectively connected to the three sets of grinding wheels. When grinding the concrete floor, the support device synchronously drives the three sets of supports to rotate and swing downwards, causing the three sets of supports to drive the three sets of grinding wheels downwards to contact the ground. Then, the three sets of first motors drive the three sets of grinding wheels to rotate, thereby grinding the ground. This reduces the energy consumption of using multiple power sources for the three sets of supports. One set of supports can be quickly disassembled via the support device, thus facilitating a reduction in the overall width of the grinding machine, making it easier to transport using a small truck and improving the ease of use of the grinding machine.
[0006] Preferably, the support device includes a connecting assembly, a guiding assembly, a base, three sets of support shafts, three sets of sprockets, three sets of chains, a fixing component, and a hydraulic cylinder. The base is installed on the top of the base. The three sets of supports are rotatably installed on the base via the guiding assembly, and one set of supports is detachable from the base. All three sets of support shafts are installed on the outer wall of the base. The three sets of sprockets are respectively installed on the outer wall of the three sets of support shafts. The hydraulic cylinder is installed on the top of the base. The fixing component is installed on the moving end of the hydraulic cylinder. One end of the three sets of chains is installed on the outer wall of the fixing component. The other end of the three sets of chains is connected to the three sets of supports via the connecting assembly, and one set of chains is detachable from the supports. The three sets of sprockets guide and support the three sets of chains. The hydraulic cylinder drives the fixing component to move downward, causing the fixing component to pull the three sets of supports to rotate and swing upward through the cooperation of the three sets of chains and the three sets of sprockets, thereby facilitating the separation of the three sets of grinding wheels from the ground. Conversely, it causes the grinding wheels to move downward and contact the ground.
[0007] Preferably, the connecting assembly includes three sets of fixing plates, three sets of connectors, hooks, and crossbars. The three sets of fixing plates are respectively installed on the outer walls of the three sets of brackets, the three sets of connectors are respectively installed on the three sets of fixing plates, the hooks are installed on the ends of one set of chains, and the crossbars are installed on one set of connectors. The hooks and crossbars are connected in a cooperative manner. The remaining two sets of chains are rotatably connected to the remaining two sets of connectors via connecting shafts. After the fixings move downward, they pull the brackets through the chains, thereby facilitating the rotation and swing of the brackets. The cooperation between the hooks and crossbars makes it easy to separate one set of chains from one set of brackets, improving the convenience of disassembling one set of brackets.
[0008] Preferably, the guide assembly includes three sets of pins and three sets of nuts. All three sets of pins are mounted on the base, and the three sets of nuts are respectively fitted onto the three sets of pins. The ends of the three sets of brackets are rotatably mounted onto the three sets of pins. The pins guide and support the brackets, improving the stability of the brackets' rotation and swing. By disassembling one set of pins and nuts, the convenience of disassembling one set of brackets is improved.
[0009] Preferably, it also includes multiple sets of wheels, all of which are installed on the lower part of the base; by setting multiple sets of wheels, the convenience of moving the grinding machine is improved.
[0010] Preferably, the system also includes multiple sets of second motors, which are respectively mounted on multiple sets of wheel sets, and the output ends of the multiple sets of second motors are respectively connected to the walking wheels of the multiple sets of wheel sets; by driving the walking wheels with the second motors, the convenience of the wheel sets driving the base to move is improved.
[0011] Preferably, the first motor is fixed to the support platform using a connecting seat; this improves the ease of disassembly between the first motor and the support platform.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: When it is necessary to grind the concrete ground, the support device synchronously drives the three sets of brackets to rotate and swing downward, so that the three sets of brackets drive the three sets of grinding wheels to contact the ground downward. Then, the three sets of first motors drive the three sets of grinding wheels to rotate, so that the three sets of grinding wheels grind the ground. This reduces the energy consumption of the three sets of brackets using multiple power sources. One set of brackets can be quickly disassembled through the support device, which makes it easier to reduce the overall width of the grinder, and thus makes it easier to transport with a small truck, improving the ease of use of the grinder.
