Description

Technical Field

[0001] This utility model relates to the field of floor construction technology, and in particular to a device for extending the life of floor polishing equipment. Background Technology

[0002] A floor polishing machine, also known as a terrazzo machine, is a construction machine equipped with a rotating grinding disc for polishing terrazzo floors. It's a type of mechanical equipment used for leveling, smoothing, and finishing cement concrete surfaces. In construction projects, large areas of floor surface polishing are frequently required, and floor polishing machines are now widely used. However, existing floor polishing machines lack cooling components, generating heat during operation. Prolonged exposure to high temperatures can lead to aging and damage of parts, thus affecting the machine's lifespan.

[0003] A floor polishing machine disclosed in patent application CN210741330U includes a housing with an open bottom. A horizontal mounting plate is located in the middle of the housing. A motor is located at the top center of the mounting plate, and a battery is located on one side of the motor. The drive end of the motor passes through the mounting plate and connects to a drive plate located below the mounting plate. Three polishing discs arranged in a triangular pattern are located at the bottom of the drive plate, with the bottom of each disc protruding from the housing. An extension plate extending beyond the housing is located on one side of the top of the housing. A push rod is located on the edge of the extension plate away from the housing. A handle and a control panel are located at the top of the push rod. A controller is located within the control panel, which includes control buttons and a display screen. The control buttons, display screen, motor, and battery are all connected to the controller. Two rollers are arranged side-by-side at the bottom of the extension plate via a support rod. This invention features three polishing discs that rotate for better polishing results.

[0004] While the aforementioned patent achieves the goal of having three polishing discs driven by a single motor, which not only revolve around the central axis but also rotate on their own axis, thus enhancing the floor polishing effect, the motor on the drive board of this device drives the three polishing discs to rotate and polish via gear meshing. The gears have no protective sleeves, making them susceptible to the influence of the working environment during construction, which in turn affects the polishing effect and the service life of the equipment. Furthermore, the uniform height of the three polishing discs means that uneven force is applied to uneven surfaces, affecting the contact area between the polishing discs and the ground, and thus impacting the floor polishing effect. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] The purpose of this utility model is to provide a device to extend the life of a floor polishing equipment, in order to solve the problems mentioned in the background art. The motor on the drive board of the device drives three polishing discs to rotate and polish by gear meshing. The gears have no protective sleeves, and the rotation of the gears is easily affected by the working environment during construction, which in turn affects the polishing effect and the service life of the equipment. In addition, the three polishing discs are at the same height, and the uneven force on uneven ground affects the contact area between the polishing discs and the ground, thus affecting the floor polishing effect.

[0015] (III) Beneficial Effects

[0016] This utility model provides a device for extending the life of floor polishing equipment, which has the following beneficial effects:

[0017] 1. This floor polishing equipment extends the lifespan of the floor polishing machine. Through the design of a motor, gear reducer, cross-shaped grinding disc, and efficiency-enhancing mechanism, when the equipment is in operation, the motor starts, and the gear reducer drives the grinding disc below the cross-shaped grinding disc to rotate at high speed, polishing the floor surface. The grinding disc surface is curved, increasing the contact area between the grinding disc and the floor. This larger contact area allows for a more even distribution of grinding force on the grinding disc surface, avoiding localized over-grinding or under-grinding, thus improving processing quality. Anti-slip strips on the curved surface increase friction between the grinding disc and the floor, preventing the grinding disc from sliding or shifting during high-speed rotation, thereby extending the lifespan of the grinding disc and optimizing the surface treatment effect.

[0018] 2. This equipment for extending the lifespan of floor polishing equipment utilizes a water storage tank, a refrigeration mechanism, and a cooling mechanism. During operation, a temperature sensor continuously monitors the temperature inside the water storage tank and converts it into an electrical signal, which is then transmitted to the temperature controller. The temperature controller compares the preset temperature value with the sensor signal to control the operation of the semiconductor cooling chip, activating the circulating water pump. Water flows through the water-cooled wall channels, carrying away heat and cooling the motor and gear reducer. This improves the equipment's heat dissipation, prevents overheating-related damage, and ultimately extends the equipment's lifespan. Attached Figure Description

The cooling mechanism 6 includes a circulating water pump 601 that runs through one side of the water storage tank 5. An inlet pipe 602 runs through one side of the circulating water pump 601. Two sets of water-cooled walls 603 run through one side of the inlet pipe 602. Multiple water flow channels 604 are opened inside the water-cooled walls 603.

An arc-shaped surface 902 is provided on the bottom of the grinding disc 901. Multiple anti-slip strips 903 are provided on the surface of the arc-shaped surface 902.

[0026] The semiconductor cooling chip 401 is fixedly connected to the bottom of the water storage tank 5. The surface of the semiconductor cooling chip 401 is provided with a heat insulation shell 10. The temperature sensor 402 is fixedly connected to the inner wall of the water storage tank 5. The heat insulation shell 10 plays a role in cooling and heat preservation.

[0027] The surface of the gear reducer 7 is provided with a square aluminum shell 11, which is threaded to the bottom of the frame 1. The square aluminum shell 11 serves to protect the internal gear reducer 7.

[0028] The outlet pipe 605 is connected to one side of the circulating water pump 601. Two sets of water-cooled walls 603 are respectively threaded to one side of the motor 2 and the square aluminum shell 11. The water-cooled walls 603 are used to cool the water.

[0029] The output end of the motor 2 is rotatably connected to a V-belt 12, and a rotating wheel 13 is rotatably connected to the surface of the V-belt 12. The rotating wheel 13 is splined to one side of the gear reducer 7. The V-belt 12 drives the gear reducer 7 to move.

Motor 2 drives the grinding disc 901 under the cross grinding disc 8 to rotate at high speed through gear reducer 7 to polish the floor surface. The surface of the grinding disc 901 is curved, which increases the contact area between the grinding disc 901 and the floor.

The water flows through the water flow channel 604 of the water-cooled wall 603, carrying away heat and cooling the motor 2 and the gear reducer 7.
