However, the counterweights not only need to be heavy, making the grinding robot more cumbersome, but also the counterweights are difficult to move. They either need to be moved manually or driven by high-power motors, which is inconvenient for manual operation and has high motor costs. Utility Model Content

[0030] The following is combined Figures 1 to 5 This invention describes an adjustable counterweight floor grinding robot, comprising a mobile frame 1, a carriage 2, a grinding disc 3, and a telescopic drive component 4.

[0031] The vehicle body 2 can be slidably mounted above the mobile frame 1 in the front-to-back direction;

[0032] The grinding disc 3 is disposed below the front end of the mobile frame 1;

[0033] The fixed end of the telescopic drive component 4 is connected to the bottom of the vehicle body 2, and the driving end of the telescopic drive component 4 is connected to the mobile frame 1; under the drive of the telescopic drive component 4, the vehicle body 2 can slide in the front-back direction.

[0034] The floor grinding robot grinds the floor using a grinding disc 3. Therefore, the grinding disc 3 needs to apply pressure to the floor to improve grinding efficiency. Most current floor grinding robots use counterweights to increase the weight and pressure on the grinding disc 3 to improve grinding efficiency. However, counterweights not only need to be heavy, making the entire grinding robot more cumbersome, but also require manual handling or high-power motors for movement. Manual operation is inconvenient, and motors are expensive. Therefore, this application provides a floor grinding robot with adjustable counterweights. Specifically, the carriage 2 is used to place items such as the control board and has a certain weight. The carriage 2 can be slidably mounted on the mobile frame 1. The carriage 2 replaces the function of the counterweight. When it is moved above the grinding disc 3 by the telescopic drive 4, it can apply pressure to the grinding disc 3. When pressure is not needed, the carriage 2 can be moved away from the grinding disc 3 by the telescopic drive 4. The operation is convenient and simple.

[0035] Furthermore, sliding blocks 21 are respectively provided on the bottom of the left and right sides of the vehicle body 2, and guide rails 11 are respectively provided on the left and right sides of the mobile frame 1. The sliding blocks 21 are sleeved on the outside of the guide rails 11, and the sliding blocks 21 are slidably connected to the guide rails 11.

[0036] Specifically, in this embodiment, the left and right sides of the carriage 2 rest on the left and right sides of the mobile frame 1, respectively, and are connected to the guide rail 11 of the mobile frame 1 through the sliding block 21. The sliding block 21 covers the guide rail 11, which can not only provide support, but also guide the sliding movement of the carriage 2, so as to prevent the carriage 2 from deviating during movement.

[0037] Furthermore, at least two sliding blocks 21 are provided on the same side of the carriage 2. The two sliding blocks 21 are fixedly provided at the front and rear ends of the carriage 2, respectively, and the two sliding blocks 21 are slidably connected to the guide rail 11.

[0038] Specifically, in this embodiment, at least two sliding blocks 21 are provided on the same side. The two sliding blocks 21 are respectively installed at the front and rear ends of the carriage 2 to provide support during the movement of the carriage 2. This can ensure the balance of the carriage 2 in the front and rear directions during the sliding movement and prevent the carriage 2 from tilting or shifting.

[0039] Furthermore, a dustproof plate 22 is provided at the bottom of the vehicle body 2. The dustproof plate 22 includes four vertical plates connected end to end. The four plates are respectively arranged around the sliding block 21, and the vertical plates at the front and rear ends are provided with clearance holes 221.

[0040] Specifically, since the floor grinding robot generates a large amount of dust and powder during operation, if the dust and powder adhere to the sliding block 21, it will reduce the lubrication between the sliding block 21 and the guide rail 11, causing the movement of the carriage 2 to become stuck. Wear on the sliding block 21 and the guide rail 11 will also shorten their service life. In this embodiment, four vertical plates connected end to end surround the sliding block 21 to protect the guide rail 11 and the sliding block 21. The clearance hole 221 is used to cover the guide rail 11 and also to seal both sides of the guide rail 11, thereby reducing the amount of dust entering between the guide rail 11 and the sliding block 21 and extending the service life of the sliding block 21 and the guide rail 11.

[0041] Furthermore, protective covers 23 are respectively provided at the front and rear ends of the sliding block 21. One side of the protective cover 23 is fixedly connected to the sliding block 21, and a guide rail hole 231 is provided at the bottom of the protective cover 23.

[0042] Specifically, in this embodiment, protective covers 23 are provided at the front and rear ends of the sliding block 21, which can prevent collisions when the telescopic drive 4 drives the carriage 2 to the front and rear ends. If a collision occurs, it will first hit the protective cover 23, thereby protecting the sliding block 21. The guide rail hole 231 of the protective cover 23 avoids the guide rail 11, so that the protective cover 23 can cover both sides of the guide rail 11, further preventing dust from entering.

[0043] Furthermore, limit blocks 12 are respectively provided at the front and rear ends of the mobile frame 1.

[0044] Specifically, in this embodiment, limit blocks 12 are respectively provided at the front and rear ends of the mobile frame 1 to prevent the car body 2 from slipping off the mobile frame 1 during sliding movement, which would cause the car body 2 to fall and be damaged, thereby improving the safety performance of the robot.

[0045] Furthermore, the telescopic drive component 4 is any one of a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder.

[0046] Specifically, in this embodiment, the telescopic drive component 4 can be any one of a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder. The cylinder body is connected to the vehicle body 2, and the piston rod is connected to the movable frame 1, thereby enabling the vehicle body 2 and the movable frame 1 to move relative to each other.

[0047] Furthermore, the front end of the mobile frame 1 is provided with a drive shaft 13, and the drive end of the telescopic drive component 4 is hinged to the drive shaft 13.

[0048] Specifically, if the drive end of the telescopic drive component 4 is fixedly locked to the mobile frame 1, and if the telescopic drive component 4 is tilted or uneven, it is easy to cause the movement direction of the vehicle body 2 to change, resulting in damage to the telescopic drive component 4. In this embodiment, the drive end of the telescopic drive component 4 is rotatably connected to the drive shaft 13 of the mobile frame 1. The rotatable connection method is relatively flexible and can effectively avoid damage to the telescopic drive component 4.

[0049] Furthermore, the front end of the mobile frame 1 is provided with a drive mounting plate 14, and the upper surface of the drive mounting plate 14 is provided with two connecting plates 15, and the drive shaft 13 is fixedly arranged between the two connecting plates 15.

[0050] Specifically, in this embodiment, a drive mounting plate 14 is provided extending outward from the front end of the mobile frame 1, and the drive shaft 13 is mounted on two connecting plates 15 of the drive mounting plate 14, thereby realizing the installation and fixation of the drive shaft 13 and ensuring the structural stability of the drive shaft 13.

[0051] Furthermore, two parallel fixed connecting plates 24 are provided at the bottom rear end of the vehicle body 2, and a connecting shaft 25 is provided between the fixed connecting plates 24. The fixed end of the telescopic drive component 4 is hinged to the connecting shaft 25.

[0052] Specifically, in this embodiment, the fixed end of the telescopic drive component 4 is rotatably connected to the vehicle body 2 via the connecting shaft 25, making the connection between the telescopic drive component 4 and the vehicle body 2 a flexible connection. This avoids the problem of the telescopic drive component 4 tilting unevenly due to a rigid connection, which could cause the vehicle body 2 to change its direction of movement or the telescopic drive component 4 to be damaged.
