Driven by the electric telescopic device 16, the first square frame 7 and the second square frame 19 can achieve their own lifting and lowering adjustments.

[0052] like Figure 1 , 2 As shown, the outer surfaces of both sides of the sliding seat 2 are respectively provided with a third driving motor 4, the upper surface of the second guide rail 1-2 is provided with a rack structure 1-3 along the direction, the output shaft of the third driving motor 4 is connected with a gear 5, and the gear 5 is meshingly connected with the rack structure 1-3, and the leveling mechanism is driven by the third driving motor 4 to move back and forth along the guide rail mechanism.

[0054] like Figure 1-6 As shown, the first drive motor 11, the second drive motor 22, the third drive motor 4, and the electric telescopic device 16 are electrically connected to a power module (not shown) through wires and a control panel (not shown).

[0055] Embodiment 7: Based on the above embodiments, this embodiment discloses:

[0056] A leveling method for airport channel construction equipment: Figure 1-7 As shown, including:

[0057] Step A: Install the guide rail mechanism 1 on both sides of the channel earthwork 6, and adjust the guide rail mechanism 1 to be horizontal.

[0058] Step B, using the control panel to make the leveling mechanism move stepwise along the guide rail mechanism, and each step of the stepwise movement has a distance equal to the width of the first square frame or the second square frame. Since the widths of the first square frame and the second square frame are the same, with each step, the second square frame covers the range just covered by the first square frame. During the stepping process, the first square frame and the second square frame are lifted by the electric telescopic device, and after reaching the new position, the first square frame and the second square frame are placed on the earth surface at a set height.

[0059] Step C: Every time the leveling mechanism moves one step, the first area division preliminary leveling subunit is used to preliminary level the earthwork surface along the horizontal transverse direction. As the leveling mechanism moves, the second area division preliminary leveling subunit further levels the top of the earthwork preliminary leveled by the first area division preliminary leveling subunit along the horizontal longitudinal direction; the scraper finally scrapes the preliminary leveled earthwork surface.

[0060] In the step C, Figure 8 As shown, during the horizontal preliminary leveling or the horizontal further leveling, the first partition plate and the second partition plate are inserted downward to a depth that makes part of the earth surface protrude from the top of the first partition plate and the second partition plate, and part of the earth surface is lower than the top of the first partition plate or the second partition plate. As the depressions in all the first partition spaces in the first square frame or all the second partition spaces in the second square frame are filled (due to the initial deep insertion, the tops of the first partition plate and the second partition plate are easily leveled with the earth surface, but at this time there will still be some earth protruding from the top of the first partition plate and the second partition plate.

[0061] Therefore, the following steps are required), the first square frame or the second square frame is lifted upward to a set height through the electric telescopic device, and the first preliminary scraping plate or the second preliminary scraping plate is repeatedly used to fill the remaining unfilled first division space in the first square frame or the remaining unfilled second division space in the second square frame. The depressions (for each first division space or second division space, there are two situations after filling, one of which is that it is filled and there is no excess soil above the division space. In this case, there is no excess soil that can be continued to be filled after the division space is lifted.

[0062] Another situation is that the dividing space is filled, but there is still excess earth piled up on the top. By lifting, the dividing space is made to show that part of the earth protrudes out of the dividing space, and part of the earth is sunken in the dividing space, and the above operation of filling the sunken is continued). Repeat the above steps of lifting the first square frame or the second square frame by the electric telescopic device after filling, until all the first dividing spaces in the first square frame or all the second dividing spaces in the second square frame are filled and there is no earth protruding from the top of the first dividing plate or the second dividing plate above the first dividing plate or the second dividing plate. In the case where all the dividing spaces in the first square frame are filled, due to the uneven distribution of the top of the earth, the heights of the first dividing spaces after being filled are likely to be inconsistent. Therefore, it is necessary to perform longitudinal horizontal leveling by stepping. After the longitudinal horizontal leveling, the top of the earth can be truly initially leveled, and the density of the top of the earth reaches a balanced state.

[0063] Working principle of the present invention:

[0064] The soil in the trough is uneven in the initial state. If it is directly scraped with a scraper, even if a guide rail is installed, the scraped part will be dense in some places and fluffy in others, thus affecting the quality of subsequent construction. Therefore, the present invention sets up a regional division type preliminary leveling, wherein when the first regional division preliminary leveling subunit is working, the first square frame is pressed down on the top of the soil, and the top of the soil is divided into a plurality of first division spaces by the first division plate. The amount of soil in each first division space is different, and the distribution of soil in each part of each first division space is also different. By moving the first preliminary scraping plate back and forth, the soil in each first division space arranged horizontally can be evenly distributed after preliminary leveling.

[0065] However, this does not mean that the top of the earthwork within the first square frame is truly preliminarily leveled, because there may be more earthwork in the front part of the first square frame and less earthwork in the back, or more earthwork in the middle and less earthwork at both ends, or other situations. Therefore, further preliminarily leveling is required along the horizontal longitudinal direction. During further preliminarily leveling, the leveling mechanism moves forward, and the second square frame overlaps the original position of the first square frame. At this time, the earthwork in the second square frame is the earthwork that has been preliminarily leveled horizontally.

[0066] Then, using the same principle, the second dividing plate divides the top of the earthwork into several second divided spaces, and the second preliminary scraping plate moves back and forth to level and evenly distribute the earthwork in the second divided space in the front-to-back direction. At this time, the preliminary leveling of the top of the earthwork is truly achieved. As the leveling mechanism further steps forward, the scraper finally levels the top of the earthwork after preliminary leveling. Because the top of the earthwork is divided and initially leveled from the longitudinal and transverse angles before leveling, the earthwork is evenly distributed, and the density is balanced after leveling, which is conducive to improving the quality of subsequent construction.

[0067] During the movement, the scraping edge pushes the soil into the first dividing space or the second dividing space through the vertical surface, while the excess soil passes through the scraping edge along the inclined surface where the waist of the isosceles triangle is located, through the strip groove, and remains on the rear side of the moving direction of the scraping edge, thereby avoiding the soil being pushed to one end of the top of the earthwork within the range of the first square frame or the second square frame during the initial leveling, ensuring the balance of the earthwork after the initial leveling.

[0068] The implementation method of step C of the present invention is: the parameters for lifting the height of the first square frame and the second square frame each time and the number of times the first preliminary scraping plate and the second preliminary scraping plate repeatedly move at each height are set through the control panel, and the depth of the first square frame and the second square frame initially buried in the soil can be controlled manually.

The airport channel rapid leveling device according to claim 4, characterized in that: The scraping unit comprises a baffle fixedly connected to the inner surface of the sliding seat through a connecting rod, the inner surface of the baffle is gap-matched with the outer surfaces of the first square frame and the second square frame, and the rear ends of the two baffles are fixedly connected to a scraper; The first drive motor, the second drive motor, the third drive motor, and the electric telescopic device are electrically connected to the power module through wires and a control panel, respectively.

6. A method for rapid leveling of an airport channel, using the rapid leveling device for an airport channel according to any one of claims 1 to 5, characterized in that: These include: Step A: Install the guide rail mechanism on both sides of the channel earthwork and adjust the guide rail mechanism to be horizontal; Step B, the leveling mechanism is moved stepwise along the guide rail mechanism through the control panel, and the distance of each step of the stepwise movement is the width of the first square frame or the second square frame. Since the widths of the first square frame and the second square frame are the same, the second square frame covers the range just covered by the first square frame with each step of movement. During the stepping process, the first square frame and the second square frame are lifted by the electric telescopic device, and the first square frame and the second square frame are placed on the earthwork surface at a set height after reaching a new position; Step C: Every time the leveling mechanism moves one step, the first area division preliminary leveling subunit is used to preliminary level the earthwork surface along the horizontal transverse direction. As the leveling mechanism moves, the second area division preliminary leveling subunit further levels the top of the earthwork preliminary leveled by the first area division preliminary leveling subunit along the horizontal longitudinal direction; the scraper finally scrapes the preliminary leveled earthwork surface.

7. A method for rapid leveling of an airport channel as claimed in claim 6, characterized in that: In the step C, during the horizontal preliminary leveling or the horizontal further leveling, the first dividing plate and the second dividing plate are inserted downward to a depth that makes part of the earth surface protrude from the top of the first dividing plate and the second dividing plate, and part of the earth surface is lower than the top of the first dividing plate or the second dividing plate. As the depressions in all the first dividing spaces in the first square frame or all the second dividing spaces in the second square frame are filled, the first square frame or the second square frame is lifted upward by the electric telescopic device to set the height, and the first preliminary scraping plate or the second preliminary scraping plate is repeatedly used to fill the depressions in the remaining unfilled first dividing spaces in the first square frame or the remaining unfilled second dividing spaces in the second square frame. The above step of lifting the first square frame or the second square frame by the electric telescopic device after filling is repeated until all the first dividing spaces in the first square frame or all the second dividing spaces in the second square frame are filled and there is no earth protruding from the top of the first dividing plate or the second dividing plate above the first dividing plate or the second dividing plate.
