Various combinations of the specific features in the embodiments described in the detailed description may be made without contradiction, for example, different embodiments may be formed by different combinations of the specific features, and various possible combinations of the specific features in the present invention will not be further described in order to avoid unnecessary repetition.
In particular embodiments, the flattening apparatus provided by embodiments of the present invention may be used to flatten an enclosed layer of any facility. For example, the leveling device can be used for leveling a closed layer of a bridge floor, the leveling device can also be used for leveling a closed layer of a roadbed, and the leveling device can also be used for leveling a closed layer of a ballastless track. For convenience of description, in the following embodiments, the closing layer is used for leveling the closing layer of the ballastless track, and the movement in the direction away from the closing layer is referred to as upward movement, and the movement close to the closing layer is referred to as downward movement.
In some embodiments, as shown in figure 1, the flattening apparatus 1 comprises: mounting bracket 10, leveling element 20, leveling adjustment 30, and mobile drive 40. The mounting frame 10 is located above the closed layer, and optionally, the mounting frame 10 is held by a constructor or suspended above the closed layer by hoisting; optionally, the mounting 10 is provided with a support structure by which the mounting 10 is supported above the enclosure.

Alternatively, the mounting frame 10 is made of a light metal material, such as aluminum, so that a constructor can move the mounting frame 10 and push the mounting frame 10 along the extending direction of the ballastless track.
The leveling element 20 is connected with the mounting rack 10, and in a state that the mounting rack 10 is located above the closed layer, the leveling element 20 can be in contact with the surface of the closed layer, and in a process that the mounting rack 10 moves along the extending direction of the ballastless track, the leveling element moves along the extending direction of the ballastless track along with the mounting rack 10, and the closed layer is leveled.
It should be noted that the specific structure of the leveling element 20 is determined according to the shape of the surface of the closed layer required by design, so that the cross-sectional shape of the bottom of the leveling element 20 is consistent with the cross-sectional shape of the surface of the closed layer required by design, wherein the cross-section refers to a plane perpendicular to the extending direction of the ballastless track. For example, the design requires that the surface of the sealing layer be a plane, the cross-sectional shape of the surface of the sealing layer be a straight line segment, and the cross-sectional shape of the bottom of leveling element 20 be a straight line segment; for example, the design requires that the surface of the sealing layer be a curved surface, the cross-sectional shape of the surface of the sealing layer be a curved segment, and then the cross-sectional shape of the bottom of the leveling member 20 be a curved segment; for example, if the surface of the sealing layer is designed to be two planes with a predetermined included angle, and the cross-sectional shape of the surface of the sealing layer is two straight line segments with a predetermined included angle, the cross-sectional shape of the bottom of the leveling element 20 is also two straight line segments with a predetermined included angle. Optionally, the extending direction of the leveling element 20 is substantially perpendicular to the extending direction of the ballastless track, that is, a certain error in the placing angle of the leveling element 20 is allowed, for example, it can be understood that an absolute value of a difference between an included angle between the extending direction of the leveling element 20 and the extending direction of the ballastless track and 90 ° is smaller than a preset threshold value, for example, the threshold value may be 5 °, and then the included angle between the extending direction of the leveling element 20 and the extending direction of the ballastless track is between 85 ° and 95 °. The extending direction of the leveling element 20 is the largest dimension among the length, width and height of the leveling element 20, and the extending direction of the leveling element 20 is substantially perpendicular to the extending direction of the ballastless track, so as to fully utilize the dimension of the leveling element 20 in the extending direction, that is, the leveling element 20 can level a larger area of a closed layer as much as possible under the condition that the dimension of the leveling element 20 in the extending direction is not changed.

Alternatively, the leveling adjusting member 30 may be linearly moved in a direction perpendicular to the bottom surface of the mounting bracket 10, and one end of the leveling adjusting member 30 is connected to the leveling member 20. In a state where the mounting block 10 is located above the sealing layer and the bottom surface of the mounting block 10 is substantially parallel to the surface of the sealing layer, the leveling adjusting member 30 is linearly moved in a direction perpendicular to the bottom surface of the mounting block 10, so as to drive the leveling element 20 to linearly move in a direction perpendicular to the bottom surface of the mounting block 10, thereby adjusting the distance between the leveling element 20 and the sealing layer.

It should be noted that the movable driving member 40 is any structure capable of moving the leveling device 1 along the enclosed layer, and the specific structure of the movable driving member 40 will be described below with reference to fig. 2 and 3, and it should be understood by those skilled in the art that the movable driving member 40 may be other structures besides the structure shown in fig. 2 and 3.

To explain the movement of each part of the first type of movable driving member 40A and the principle of the first type of movable driving member 40A driving the leveling device 1 to move along the enclosed floor, the output shaft 411A of the rotating motor rotates counterclockwise to drive the linear motor 42A, the crawling foot 43A and the friction pad 44A to rotate, so that the friction pad 44A is far away from the supporting surface; after the rotation of the output shaft 411A of the rotating motor is completed, the output shaft 421A of the linear motor is extended to drive the crawling foot 43A and the friction pad 44A to move forward by a preset distance; after the extension of the output shaft 421A of the linear motor is completed, the output shaft 411A of the rotary motor rotates clockwise to press the friction pad 44A against the support surface; after the output shaft 411A of the rotary motor is rotated, the output shaft 421A of the linear motor is shortened and drives the crawling foot 43A and the friction pad 44A to move backwards, so that the leveling device 1 is driven to move along the sealing layer by a preset distance under the action of friction between the friction pad 44A and the supporting layer, and the first type of moving driving member 40A can continuously move along the sealing layer by circularly executing the process.
As shown in FIG. 3, a second type of mobile drive member 40B includes: drive motor 41B and road wheels 46B.

As shown in fig. 1, the displacement value of the leveling element 20 along the adjusting direction is in positive correlation with the displacement value of the leveling element 20 along the sealing layer, that is, in the process of the leveling device 1 moving along the sealing layer, the leveling element 20 moves along the sealing layer along with the mounting rack 10, the leveling adjusting part 30 drives the leveling element 20 to move downwards, so that the leveling element 20 presses the sealing layer downwards while leveling the sealing layer, and the amount of the leveling element 20 pressing the sealing layer downwards is in positive correlation with the displacement value of the leveling element 20 along the sealing layer, thereby forming a preset included angle between the extending direction and the horizontal direction of the sealing layer and forming a longitudinal slope of the sealing layer while the leveling element 20 levels the sealing layer. The process of forming the sealing layer with a longitudinal slope on the flattening element 20 is exemplified below with reference to fig. 4. In the process of constructing the sealing layer, filling concrete slurry to a height higher than a marking line A to form a sealing layer I which is not leveled, wherein the marking line A is a height line of the sealing layer required by design; after the concrete slurry is filled, placing the mounting frame 10 above the unbeveled closed layer I and adjusting the height of the leveling element 20, so that at least one part of the leveling element 20 is pressed into the unbeveled closed layer I, and the bottom of the leveling element 20 is flush with the marking line A; after the leveling element 20 is adjusted in height, the movable driving member 40 is started to drive the leveling device 1 to move along the length direction of the ballastless track, so that the leveling element 20 moves along the length direction of the ballastless track along with the mounting rack 10 (indicated by a solid arrow in fig. 4), meanwhile, the leveling adjusting member 30 drives the leveling element 20 to move along the adjusting direction (indicated by a dotted arrow in fig. 4), in the process, the leveling element 20 pushes the concrete slurry of the non-leveled sealing layer I higher than the standard height a along with the leveling element 20, the slurry on the surface of the sealing layer is pressed downwards, and the amount of the slurry pressed downwards by the leveling element 20 on the surface of the sealing layer is increased along with the increase of the displacement value of the leveling device 1 moving along the sealing layer, so that the non-leveled sealing layer I is leveled to be leveled into the leveled sealing layer II, and a preset longitudinal slope angle θ is formed between the extending direction B of the surface of the leveled sealing layer and the standard height a Namely, the sealing layer with the preset longitudinal slope angle theta is constructed while the sealing layer is leveled.
It should be noted that the leveling device 1 is any structure that can make the displacement value of the leveling element 20 along the adjustment direction have a positive correlation with the displacement value of the leveling element 20 along the sealing layer, for example, the leveling adjusting member 30 is connected with the movable driving member 40, the leveling element 20 is driven to move along the adjustment direction under the driving of the movable driving member 40, that is, the movable driving member 40 drives the leveling device 1 to move along the sealing layer and also drives the leveling element 20 to move along the adjustment direction through the leveling adjusting member 30, and both the movement of the leveling element 20 along the adjustment direction and the movement of the leveling device 1 along the sealing layer are driven by the movable driving member 40, so that the displacement value of the leveling element 20 along the adjustment direction has a positive correlation with the displacement value of the leveling element 20 along the sealing layer. For example, the leveling adjustment member 30 is integrated with a drive device for driving the leveling element 20 in the adjustment direction, and the displacement value output by the drive device is positively correlated with the displacement value output by the movable drive member, so that the displacement value of the leveling element 20 in the adjustment direction is positively correlated with the displacement value of the leveling element 20 in the sealing layer.
Wherein the specific relationship between the displacement value of the flattening element 20 in the adjustment direction and the displacement value of the flattening element 20 along the sealing layer is determined according to the designed longitudinal slope angle of the sealing layer. For convenience of explanation, the following description will be given with reference to fig. 5, taking as an example the displacement value of the flattening element 20 in the adjustment direction as X, the angle between the adjustment direction and the horizontal direction as α, the displacement value of the flattening element 20 along the sealing layer as Y, and the designed longitudinal slope angle of the sealing layer as θ, and exemplifies the process of determining the specific relationship between the displacement value of the flattening element 20 in the adjustment direction and the displacement value of the apparatus 1 according to the designed longitudinal slope angle of the sealing layer. According to the sine theorem, the displacement value X of the flattening element 20 along the adjustment direction is related to the displacement value Y of the flattening element 20 along the sealing layer by:
according to formula (1):
wherein, in a state that the adjusting direction is vertical to the horizontal direction, namely, an included angle alpha between the adjusting direction and the horizontal direction is
In a state of (1) will
