[0037] The use method of the construction ground leveling machine comprises the following steps:

[0038] S1, in the area needing leveling construction, according to the designed floor height, using the wall surface, building column or artificial height marker in the construction area, using the level instrument, first marking the horizontal baseline needed in the leveling construction on these markers through the multi-point setting in the whole area, when the laser level instrument is erected at any point in the construction area during the leveling construction, only the horizontal line emitted by the laser level instrument is needed to guide the leveling machine to perform the leveling work in the whole area by finding and calibrating the previously set horizontal baseline;

[0039] S2, whether the base 4 is in the horizontal state is detected by the horizontal inclination sensor 12 in the leveling mechanism, if it is in the horizontal state, the next step is entered, if the base 4 is not in the horizontal state, the second telescopic cylinder 17 will be telescoped to rotate the base 4 around the mounting shaft 11, and the leveling of the base 4 is performed by cooperating with the horizontal inclination sensor 12, so that the base 4 is in the horizontal state;

[0040] S3, the first telescopic cylinder 30 will be elongated to drive the workbench 6 to move to the upper stop point of the stroke, then the first telescopic cylinder 30 will be slowly contracted to slowly lower the workbench 6, when the photoelectric switch detects the signal emitted by the laser level instrument, the first telescopic cylinder 30 stops moving;

[0041] S4, the leveling mechanism is driven to move along the length direction of the base 4 by cooperating with the rack 8 by the first driving motor 26, at this time, the leveling wheel 33 will level the mortar, the leveling wheel 33 at the front side of the advancing direction of the rack 1 will coarsely grind the ground, and the leveling wheel 33 at the rear side of the advancing direction of the rack 1 will finely grind the mortar, so as to improve the leveling quality, after leveling, the leveling wheel 33 and the first driving motor 26 stop working, and the balance wheel 2 drives the application to advance a set distance, and the balance wheel 2 can maintain the base 4 horizontal in front and back under the action of the balance wheel 2;

[0042] S5, the steps S2, S3 and S4 are repeated until the leveling work in one direction is completed.

[0043] In the process of leveling the ground by the leveling wheel 33 in S4, when the photoelectric switch cannot receive the signal sent by the laser level, the first driving motor 26 stops moving, and steps S2 and S3 are repeated to ensure that the base 4 is in a horizontal state, and the height of the workbench 6 and the leveling wheel 33 in the workbench 6 relative to the laser level is consistent, and then step S4 is continued.

[0044] The principle of the application: in the application of the application, first set up the laser level according to the required thickness of the mortar, since the distance from the lower end surface of the leveling wheel to the photoelectric switch is constant, the height of the laser level is the distance from the upper end surface of the mortar to the photoelectric switch plus the distance from the lower end surface of the leveling wheel to the photoelectric switch. In the process of applying the application to the laying of mortar in a large area, it is usually necessary to move the laser level, and in the area where leveling construction is required, according to the designed floor height, the wall surface, building column or artificial height marker in the construction area is used, and the leveling instrument is used to mark the horizontal baseline required for leveling construction by setting up multiple points in the whole area. When setting up the laser level at any point in the construction area during leveling construction, only the previously set horizontal baseline needs to be found and calibrated, and the horizontal line emitted by the laser level can be used to guide the leveling machine to perform leveling work in the whole area, so as to ensure that the height of the laser level remains constant during movement and reduce the error caused by the movement of the laser level. The inclination sensor 12 under the base 4 detects whether the base 4 is in a horizontal state, and if the base 4 is not in a horizontal state, the second telescopic cylinder 17 is controlled to move, extend or shorten, and the base 4 is leveled, so as to ensure that the base is always in a horizontal state. The laser level determines the height of the workbench, and the photoelectric switch (not shown in the figure) is fixed on one end of the workbench 6 through the mounting rod. The mounting rod can lift the height of the photoelectric switch to avoid blocking the signal emitted by the external laser level. When working, the first telescopic cylinder 30 will be extended to drive the workbench 6 to move to the upper stop point of the stroke, and then the first telescopic cylinder 30 will be slowly retracted to drive the workbench 6 to slowly descend. When the photoelectric switch detects the signal emitted by the laser level, the first telescopic cylinder 30 stops moving, and the leveling wheel 33 maintains a constant height relative to the laser level, thereby realizing the thickness control of the mortar. The balance wheels 2 are arranged on the left and right sides of the frame 1, and the self-balancing 2 adopts the balance wheels available on the market, which can maintain stability in the forward and backward directions. The balance wheels 2 drive the application to move forward and backward, which is more convenient than the conventional track type movement. The differential motion of the balance wheels 2 on both sides can realize reversing, and compared with the track or belt, the application can avoid the falling mortar between the driving roller and the walking belt, causing wear and jam.The balancing wheel 2 stops moving after setting the distance, at this time the first drive motor 26 drives the driving gear 9 to rotate forward and backward regularly, in the process of forward and backward rotation of the driving gear 9, the driving gear 9 cooperates with the rack 8 to drive the support frame 5 and the workbench 6 in the support frame 5 to move horizontally, so that the leveling wheel 33 under the motor box 32 of the workbench 6 can level the mortar ground, the leveling wheel 33 is easy to throw up the mortar when working, which is easy to cause the mortar to accumulate between the gear and the rack, affecting the horizontal movement of the leveling wheel 33, the teeth of the rack 8 of the application are exposed to the base 4, so that the mortar will naturally fall under the action of gravity, preventing affecting the cooperation of the driving gear 9 and the rack 8, so that the workbench can move stably along the length direction of the base 4, and in order to improve the stability of the movement of the workbench 6, the guide block 10 and the roller 24 are further arranged below the support frame 5, the guide block 10 can play the role of guiding and limiting, and the arrangement of the roller can further support the support frame 5. Since the leveling wheel 33 has two groups and is arranged at both ends of the mounting plate 31, located on the front and rear sides of the base 4, the leveling wheel 33 on the front side of the base 4 is a coarse grinding wheel, and the leveling wheel 33 on the rear side of the base 4 is a fine grinding wheel, so that the pressure marks generated by the balancing wheel can be eliminated. After the leveling is completed once, the balancing wheel drives the application to move the same distance again, and the leveling mechanism continues to level. After completing the leveling in the straight line direction, the reversing is realized through the differential motion of the balancing wheels 2 on both sides of the rack 1, and the leveling continues, which is faster.
