The frame is movable, and a concave cavity 4 is arranged in the middle of the front end of the frame 1. A lifting shaft 5 is rotatably connected in the concave cavity 4, and the axis of the lifting shaft 5 extends in the left and right directions; the front end of the lifting connecting frame 3 is connected to the grinding assembly 2, so that the grinding assembly and the lifting connecting frame are connected as a whole; the rear end of the lifting connecting frame 3 extends into the concave cavity 4 and is fixedly connected to the lifting shaft 5, that is: the lifting shaft It is fixed as a whole with the lifting connecting frame, and the lifting connecting frame is rotatably connected to the frame through the lifting shaft, and the lifting connecting frame can swing up and down around the axis of the lifting shaft; a downwardly extending driving rocker arm 6 is fixed to the middle of the lifting shaft 5, and the lower end of the driving rocker arm 6 is hinged to the piston rod of the driving cylinder 7 arranged inside the concave cavity 4. When the piston of the driving cylinder 7 is extended and retracted, the lifting connecting frame 3 is driven to swing through the driving rocker arm 6, and the lifting connecting frame 3 drives the grinding assembly 2 to move, thereby adjusting the grinding height of the grinding assembly; the floor laser leveling unit is connected to the driving cylinder 7, and the floor laser leveling unit is used to determine the distance that the grinding assembly needs to be adjusted upward or downward, and then the movement of the grinding assembly is controlled by the driving cylinder. By combining the floor laser leveling unit with the adjustment structure consisting of a lifting connecting frame, a driving rocker arm, a lifting shaft and a driving cylinder, the floor laser leveling unit determines the distance that needs to be moved up or down during the grinding process, and then adjusts the grinding height through the adjustment structure to ensure the horizontality of the grinding. It is easy and flexible to use, and it is convenient to adjust the grinding height during the grinding process.

[0028] In this embodiment, the driving rocker arm 6 is extended downward, and the lifting shaft 5 is fixedly passed through the upper end of the driving rocker arm 6. The lower end of the driving rocker arm 6 is connected to the piston rod of the driving cylinder 7 arranged in the front and rear directions. When the piston rod of the driving cylinder 7 extends forward, the driving rocker arm rotates clockwise, and the driving rocker arm 6 drives the lifting shaft 5 to rotate in the clockwise direction. The lifting shaft 5 drives the lifting connecting frame 3 to swing upward, and the lifting connecting frame 3 pulls the grinding assembly 2 to move upward; when the piston rod of the driving cylinder retracts backward, the driving rocker arm drives the lifting shaft to rotate counterclockwise, and the lifting shaft drives the lifting connecting frame to swing downward, and the lifting connecting frame pulls the grinding assembly to move downward, thereby realizing the up and down adjustment of the grinding height.

[0029] In this embodiment, Figure 8It is a schematic diagram of a floor laser leveling unit, which includes a laser emitting device 8, a laser receiving device 9, and a control device connected to the laser receiving device 9.

The laser emitting device 8 is arranged on the peripheral side of the ground to be ground, and the laser emitted by the laser emitting device 8 forms a reference surface; the laser receiving device 9 is arranged on the grinding assembly 2 and receives the laser emitted by the laser emitting device 8. The laser receiving device receives the laser emitted by the laser emitting device (a laser leveling device may be used), and the laser is converted into an electrical signal by the laser receiving device and output to the control device. Based on the received electrical signal, the control device controls the driving cylinder to work and adjusts the grinding height of the grinding assembly.

[0030] Preferably, there may be one or two laser receiving devices. The laser emitting device may be a laser transmitter, and the laser receiving device may be a laser receiver.

[0031] like Fig. 9 As shown in the figure, it is a schematic diagram of the arrangement of each module of the floor laser leveling unit. The laser emitted by the laser emitting device 8 forms a reference plane. The laser receiving device 9 detects the laser emitted by the laser emitting device 8 and converts it into an electrical signal and outputs it to the control device. The control device can calculate the distance that the grinding head of the grinding component 2 should move up or down based on the electrical signal, thereby controlling the piston rod of the driving cylinder 7 to extend or retract, and the grinding height of the grinding head of the grinding component 2 can be adjusted by the driving cylinder 7.

[0032] In this embodiment, the grinding assembly 2 includes a dustproof cover 10 , a grinding head 11 is arranged inside the dustproof cover 10 , and two grinding motors for driving the grinding head 11 to rotate are arranged on the top of the dustproof cover 10 .

[0033] In this embodiment, the laser receiving device 9 is on the top of the dust cover 10 of the grinding assembly. The laser receiving device can be arranged at a position close to the end of the top of the dust cover.

[0034] In this embodiment, a pair of U-shaped connecting seats 12 distributed on the left and right are arranged on the top of the dust cover body 10 of the grinding assembly 2; the lifting connecting frame 3 is an integrated structure, which includes a connecting frame body 13, and the left and right ends of the connecting frame body 13 are provided with lifting arms 14 extending forward, and the lifting arms 14 at the left and right ends of the connecting frame body 13 correspond to the positions of the pair of U-shaped connecting seats 12, and the front end of the lifting arm 14 extends into the inner side of the U-shaped connecting seat 12 corresponding to the position, and the front end of the lifting arm 14 is hinged to the U-shaped connecting seat 12 via a hinge shaft, and the axis of the hinge shaft extends in the left and right directions.

[0035] In this embodiment, a push rod 15 is fixed to the outer side surface of the lifting arm 14 , and the lower end of the push rod 15 extends downward to below the lifting arm 14 and is used to support the top of the dust cover 10 of the grinding assembly 2 .

[0036] In this embodiment, a pair of connecting plates 16 distributed on the left and right are provided inside the concave cavity 4, and the connecting plates are arranged vertically; the lifting shaft 5 is rotatably connected between the upper ends of the pair of connecting plates 16 through bearings; the rear side of the connecting frame body 13 is provided with a pair of connecting arms 17 distributed on the left and right, and the pair of connecting arms 17 both extend downward into the interior of the concave cavity 4, the pair of connecting arms 17 are located between the pair of connecting plates 16, and the lower ends of the pair of connecting arms 17 are respectively fixedly connected to the left and right ends of the lifting shaft 5.

[0037] In this embodiment, the driving oil cylinder 7 is in an inclined shape with a low front end and a high rear end. The piston rod of the driving oil cylinder 7 extends forward and the end is hinged to the lower end of the driving swing rod 6. The rear end of the driving oil cylinder 7 is hingedly mounted on a cylinder mounting seat 18, and the cylinder mounting seat 18 is fixed to the bottom of the concave cavity 4. Since the grinding assembly is heavy, and the driving oil cylinder usually has a thrust (piston rod extension process) greater than a pulling force (piston rod contraction process), when the grinding assembly needs to be lifted upward, the driving oil cylinder is in the process of the piston rod extending forward. At this time, the thrust of the driving oil cylinder is relatively large, which can better meet the lifting of the grinding assembly.

[0038] In this embodiment, the front end of the cavity 4 is open to facilitate the extension of the lower end of the driving rocker.

[0039] In the present embodiment, a method for adjusting a floor grinder based on laser leveling is provided, and the adjustment method is specifically as follows: during the operation of the floor grinder, the laser emitted by the laser emitting device 8 forms a reference plane, and the laser receiving device 9 detects the laser emitted by the laser emitting device 8 and converts it into an electrical signal and outputs it to the control device. The control device calculates the distance that the grinding component 2 needs to move up or down based on the electrical signal, thereby controlling the piston rod of the driving cylinder 7 to extend or retract, and when the piston rod of the driving cylinder 7 extends or retracts, it drives the driving rocker arm 6 to rotate, and the driving rocker arm 6 drives the lifting shaft 5 and the lifting connecting frame 3 to swing, and the lifting connecting frame 3 drives the grinding component 2 to move upward or downward, thereby adjusting the grinding height of the grinding component.

[0040] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except when it is obviously impossible to use an one-piece molding process).

[0041] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the present invention include states or shapes that are approximate, similar, or close to them.

[0042] Any component provided by the present invention may be assembled from a plurality of separate components, or may be a separate component manufactured by an integral forming process.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention, which should be included in the scope of the technical solution for protection of the present invention.
