Description

Technical Field

[0001] The utility model relates to a construction ground leveling machine, in particular to a leveling machine for leveling the ground of a construction site. Background Art

[0002] A ground leveling machine is a device used in the construction and decoration processes. Its main function is to level the surface of the ground to ensure that the ground reaches the required flatness and smoothness. The following are some of the main functions and roles of the ground leveling machine: 1. Improve the ground flatness. The ground leveling machine can effectively eliminate the unevenness on the ground, making the ground more flat, which is very important for laying floor tiles and other ground decoration materials; 2. Reduce the labor intensity. Using the ground leveling machine can greatly reduce the workload and labor intensity of manual leveling, improving the construction efficiency. The traditional manual leveling method is time-consuming and laborious, while the mechanical equipment can quickly complete the ground leveling work for large areas; 3. Improve the construction quality. The ground leveling machine can provide a uniform leveling effect, reducing the errors caused by manual operation, thereby improving the overall construction quality. A flat ground is not only beautiful but also helps the smooth progress of subsequent construction; 4. Save materials. Through precise leveling, the ground leveling machine can reduce the waste of leveling materials. For example, when using cement mortar for leveling, machine leveling can better control the thickness and avoid unnecessary material waste.

[0003] As disclosed in the patent with the application number 202211076719.4, an automatic leveling floor robot and its working method are provided. The second electric guide rail drives the lifting and leveling mechanism on the second slider to move left and right through the transmission of the second stepping motor and the first gear and rack. The setting of the double guide rail structure greatly improves the moving range of the lifting and leveling mechanism and the operation efficiency of the device. During the moving process, the first spreading wheel and the second spreading wheel at the bottom of the lifting and leveling mechanism rotate under the driving of the asynchronous motor to perform secondary spreading treatment on the mortar. However, during the actual leveling work, if the ground cannot be guaranteed to be in a completely horizontal state, the fuselage of this application will be in an inclined state, and the horizontal state of the positioning height in step three cannot be achieved, which will affect the subsequent leveling work.

A through groove 34 corresponding to the first drive motor 26 is further provided in the mounting plate 31.

[0029] The leveling wheel 33 on the front side of the frame 1 is a rough grinding wheel, and the leveling wheel 33 on the rear side of the frame 1 is a fine grinding wheel.

[0030] Principle of the utility model: When this application is in use, first set up a laser level according to the required mortar thickness. Since the distance from the lower end face of the leveling wheel to the photoelectric switch is constant, the height of the laser level is the upper end face of the required mortar plus the distance from the lower end face of the leveling wheel to the photoelectric switch. During the process of applying this application to the laying of mortar in a large area, it is usually necessary to move the laser level. In the area where leveling construction is required, according to the designed floor height, use the walls, building columns in the construction area, or manually set height marks. Using a leveling instrument, first set up at multiple points within the entire area on these markers to mark the horizontal baseline required for leveling construction. When leveling construction is carried out, when setting up the laser level at any point within the construction area, only need to find the previously set horizontal baseline and calibrate it, then the horizontal line emitted by the laser level can be used to guide the leveling machine to carry out leveling operations within the entire area, ensuring that the height remains constant during the movement of the laser level and reducing the error caused by the movement of the laser level. This application detects whether the base 4 is in a horizontal state through the inclination sensor 12 under the base 4. If the base 4 is not in a horizontal state, it will control the second telescopic cylinder 17 to move, either extend or shorten, to level the base 4, thus ensuring that the base is always in a horizontal state. The externally provided laser level determines the height at which the workbench is located. There is a photoelectric switch (not shown in the figure) on the workbench 6. The photoelectric switch can be fixed to one end of the workbench 6 through a mounting rod. The mounting rod can raise the height of the photoelectric switch to avoid other components blocking the signal emitted by the externally provided laser level. During operation, the first telescopic cylinder 30 will extend to drive the workbench 6 to move to the upper dead point of the stroke. Then the first telescopic cylinder 30 will slowly contract, driving 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, thereby maintaining a constant height of the leveling wheel 33 relative to the laser level and realizing the control of the mortar thickness. Balanced wheels 2 are provided on both the left and right sides of the frame 1 of this application. Self-balancing 2 uses commercially available balanced wheels, which can maintain stability in the front and rear directions. This application drives the front and rear movement of this application through the balanced wheels 2. Compared with the conventional tracked traveling method, the direction adjustment of this application is more convenient. The commutation can be achieved through the differential movement of the balanced wheels 2 on both sides. And compared with the advancement achieved by tracks or belts, this application can avoid the mortar splashed up from falling between the driving rollers and the running belt, causing wear and jamming.After the balancing wheel 2 moves a set distance, it will stop moving. At this time, the first drive motor 26 will drive the driving gear 9 to rotate forward and backward regularly. During the forward and backward rotation of the driving gear 9, it will cooperate with the rack 8 to drive the support frame 5 and the workbench 6 in the support frame 5 to move horizontally. Thus, the leveling wheel 33 under the motor box 32 of the workbench 6 can level the mortar floor. When the leveling wheel 33 is working, it is easy to throw up the mortar, which easily causes the mortar to accumulate between the gear and the rack, affecting the horizontal movement of the leveling wheel 33. In this application, the teeth of the rack 8 protrude from the base 4. Thus, under the action of gravity, the mortar will naturally fall, preventing it from affecting the cooperation between the driving gear 9 and the rack 8. Thus, 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, guide blocks 10 and rollers 24 are also provided under the support frame 5. The guide blocks 10 can play a role in guiding and limiting, and the setting of the rollers can further support the support frame 5. Since there are two groups of leveling wheels 33, and they are arranged at both ends of the mounting plate 31, on the front and rear sides of the base 4. The leveling wheel 33 on the front side of the base 4 is a rough grinding wheel, and the leveling wheel 33 on the rear side of the base 4 is a fine grinding wheel. This can eliminate the indentations generated by the balancing wheel. After a single leveling is completed, the balancing wheel will drive this application to move forward the same distance again, and continue the leveling work through the leveling mechanism. After the leveling work is completed in the straight direction, the differential movement of the balancing wheels 2 on both sides of the frame 1 is used to achieve commutation, and the leveling continues, making the leveling faster.
