Description

Technical Field

[0001] This invention relates to the field of mortar leveling equipment technology, specifically to a mortar omnidirectional leveling chassis structure, leveling device, and method of use. Background Technology

[0002] In the construction industry, floor leveling is a fundamental process to ensure the ground is flat, firm, and meets the requirements of subsequent construction (such as laying flooring, tiles, etc.). Dry-mixed mortar leveling is a commonly used floor treatment technique in construction. It mainly utilizes dry-mixed mortar materials through mixing, spreading, and leveling operations to achieve a flat and firm base surface, providing a good foundation for subsequent decorative layers (such as tiles, flooring, paint, etc.). The leveling process can be divided into manual leveling or automated leveling using leveling robots.

[0003] Existing leveling robots generally use a rotating grinding disc to smooth the surface. During the smoothing process, a clear boundary is formed at the smoothing edge, which cannot guarantee the flatness of the entire smoothing area. Manual assistance or multiple smoothing operations are required, resulting in low leveling efficiency. At the same time, the chassis is driven by a drive system, which leaves marks on the mortar surface during movement or reversal. Summary of the Invention

[0004] Technical objective: To address the shortcomings of existing mortar leveling methods, this invention discloses a mortar omnidirectional leveling chassis structure, leveling device, and usage method.

[0005] Technical solution: To achieve the above technical objectives, the present invention adopts the following technical solution: A mortar omnidirectional leveling chassis structure includes a chassis frame and leveling tracks mounted on the chassis frame for leveling the mortar surface. The leveling tracks are at least two sets, and the two sets of leveling tracks are driven by independent drive structures. A stepping mechanism is provided on the chassis frame to drive the chassis frame to move as a whole in a direction perpendicular to the leveling tracks, so that the moved leveling tracks cover the gaps between the original leveling tracks, thereby leveling the mortar surface.

[0006] Preferably, the stepping mechanism of the present invention includes stepping brackets symmetrically arranged on both sides of the chassis frame, and an eccentric drive mechanism disposed in the chassis frame for driving the stepping brackets to move, wherein the stepping brackets and the drive end of the eccentric drive mechanism are rotatably engaged.

[0007] Preferably, the step support of the present invention includes a bottom support plate located below for contacting the mortar surface to provide support, and a side support plate fixed on the plate surface of the bottom support plate for cooperating with the drive end of the eccentric drive mechanism. A rotating shaft is provided through the side support plate, and the end of the rotating shaft is fixedly connected to the eccentric drive mechanism. The side support plate and the rotating shaft are rotatably engaged.

[0008] Preferably, the eccentric drive mechanism of the present invention includes a motor, a drive gear, an eccentric arm, and a gear shaft fixedly connected to the eccentric arm. The eccentric arm is rotatably engaged with the chassis frame, and the gear shaft is engaged with the drive gear fixed at the rotating end of the motor. The motor drives the gear shaft and the eccentric arm to rotate. The connection positions of the gear shaft and the rotating shaft with the eccentric arm are staggered, and the step movement length is controlled by the staggered distance.

[0009] Preferably, the present invention has four eccentric arms, arranged symmetrically in pairs about the chassis frame. One pair is connected to the end of the gear shaft and is directly driven by the gear shaft. The other pair of eccentric arms is connected to the end of the gear shaft and rotates synchronously through a sprocket mechanism.

[0010] Preferably, the eccentric arm of the present invention has a first position and a second position before and after the stepping mechanism moves. In the first position, the rotating shaft is located at the rear end of the rotation center of the eccentric arm, and the stepping mechanism is suspended in the air by the eccentric arm. In the second position, the rotating shaft moves to the front end of the rotation center of the eccentric arm as the eccentric arm rotates, and the bottom of the stepping mechanism contacts the mortar surface. When the eccentric arm continues to rotate, the stepping mechanism provides support force, and the chassis frame rotates around the rotating shaft with the eccentric arm, so that the chassis frame moves forward as a whole.

[0011] Preferably, the chassis frame of the present invention is provided with an inertial sensor for monitoring the deflection of the chassis frame's movement direction, and the relative rotation speed of the leveling tracks driven by different drive structures is controlled by the deflection results monitored by the inertial sensor.

[0012] This invention discloses a leveling device using the aforementioned leveling chassis structure, including a spiral auger movably mounted on the chassis frame. The spiral auger has a horizontal degree of freedom parallel to the leveling track driving the chassis frame and a vertical degree of freedom to move perpendicular to the mortar plane. The height of the leveling plane is controlled by controlling the height of the spiral auger.

[0013] This invention discloses a method of using the above-mentioned leveling device. The leveling track is driven by a drive structure to rotate, so that the entire leveling device moves horizontally on the mortar. The leveling track flattens the mortar on the moving path. At the same time, the spiral auger rotates to clear the next leveling area. After the mortar leveling of the current moving path is completed, the stepping mechanism drives the entire leveling device to move to the next leveling area and perform mortar leveling again.

[0014] Preferably, when the leveling device is moved as a whole by the stepping mechanism, the two sets of leveling tracks are divided into a first leveling track and a second leveling track along the moving direction of the leveling device driven by the stepping mechanism. After the leveling device moves, the second leveling track covers the gap area between the first leveling track and the second leveling track before the movement, and the first leveling track covers the leveling area cleaned by the spiral auger.

[0015] Beneficial effects: The mortar omnidirectional leveling chassis structure, leveling device, and usage method disclosed in this invention have the following beneficial effects: 1. The chassis frame of the present invention is moved by the leveling track, which can level the mortar while moving. At the same time, the stepping mechanism can directly move the entire chassis frame to the next leveling position without adjusting the position of the chassis frame, avoiding the problem of repeated positioning, thereby ensuring the continuity of the leveling operation and improving the leveling efficiency.

[0016] 2. The leveling track of the present invention is divided into at least two groups, and the two groups of leveling tracks are driven by independent drive structures. During the leveling process, the relative rotation speed of the two groups of leveling tracks can be flexibly controlled, thereby ensuring the stability of the overall movement path of the chassis and avoiding path deviation due to the structure of the track.

[0017] 3. This invention utilizes an eccentric drive mechanism to drive the stepping mechanism, which allows for flexible control of the stepping distance. This ensures that the leveling track after the stepping accurately covers the gap between the two leveling tracks before the stepping, thus guaranteeing the continuity of the leveling operation and eliminating the need for secondary leveling.

[0018] 4. The present invention uses a stepping mechanism to drive the chassis to move as a whole. A bottom support plate is set at the bottom of the stepping mechanism. By contacting the mortar surface with the bottom support plate, the contact area can be increased, and the indentation caused to the mortar surface by the chassis driving movement can be reduced during the stepping movement.

[0019] 5. This invention drives the eccentric arm to rotate through the gear shaft, and the adjacent eccentric arms on the same side of the chassis are connected by a sprocket mechanism to achieve synchronous and precise driving of multiple eccentric arms, thereby ensuring the consistency of the stepping mechanism's movements. Furthermore, the eccentric arms can keep the entire stepping mechanism in a suspended state during the ground leveling process, and it only comes into contact with the mortar when the chassis needs to be moved horizontally, thus avoiding affecting the leveling operation.

[0020] 6. The present invention installs an inertial sensor on the chassis frame. The inertial sensor can monitor whether the chassis movement direction deviates, and then make timely adjustments by controlling the leveling track. Attached Figure Description

Detailed Implementation

[0023] Reference will now be made in detail to embodiments of the present disclosure, one or more of which are set forth herein. Each embodiment and example is provided by way of explanation of the apparatus, composition, and materials of the present disclosure, and not by way of limitation. Rather, the following description provides convenient illustrations for implementing exemplary embodiments of the present disclosure. Indeed, it will be apparent to those skilled in the art that various modifications and variations can be made to the teachings of the present disclosure without departing from the scope or spirit of the present disclosure.

[0024] like Figures 1-4 As shown, this invention discloses a mortar omnidirectional leveling chassis structure, including a chassis frame 1 and leveling tracks 2 mounted on the chassis frame 1 for leveling the mortar surface. The leveling tracks 2 are at least two sets, and the two sets of leveling tracks 2 are driven by independent drive structures. A stepping mechanism is provided on the chassis frame 1 to drive the chassis frame to move as a whole along a direction perpendicular to the leveling tracks, so that the moved leveling tracks 2 cover the gap area between the original leveling tracks, thereby leveling the mortar surface.

[0025] The purpose of this invention is to set at least two sets of leveling tracks and drive them independently so that the direction of chassis movement can be adjusted in a timely manner during the leveling process to maintain straight-line movement. Thus, within the corresponding leveling area, the overall leveling operation can be completed according to the predetermined planned path, avoiding the problem of frequent adjustments due to the deviation of the equipment's movement trajectory. The chassis frame 1 of this invention is equipped with an inertial sensor 10 for monitoring the deviation of the direction of movement of the chassis frame 1. The relative rotation speed of the leveling tracks 2 driven by different drive structures is controlled by the deviation results monitored by the inertial sensor 10.

[0026] In some large chassis structures, if more than two groups of leveling tracks are set, the leveling tracks near the edge of the chassis can be driven by an independent drive structure, or the leveling tracks can be grouped and the leveling tracks on the same side can be driven by the same drive structure. The number of leveling tracks is preferably even, which is convenient for grouping and also helps to ensure the correction and adjustment effect of the chassis structure.

[0027] like Figure 4 As shown, this invention provides a specific embodiment of a driving structure, but does not limit the scope of protection of this invention. Those skilled in the art can use other mature track drive structures in the prior art to drive the leveling track. In the embodiment of this invention, each driving structure includes a drive motor 11, an active roller 12, and a passive roller 13. The leveling track 2 is sleeved on the active roller 12 and the passive roller 13. The driving end of the drive motor 11 is connected to the active roller 12, driving the active roller 12 to rotate and drive the leveling track. In the case where two sets of leveling tracks 2 are used in this invention, the drive motor 11 is set in the middle of the chassis frame 1 to ensure that the center of gravity of the chassis frame is in the central area, thereby ensuring the leveling effect on the mortar surface.

[0028] Meanwhile, the stepping mechanism allows for direct transport and movement of the entire chassis without the need to use leveling tracks to switch the chassis position, thus avoiding damage to the leveled mortar area caused by adjusting the chassis position.

[0029] Specifically, such as Figure 2 and Figure 3 As shown, the stepping mechanism of the present invention includes stepping brackets symmetrically arranged on both sides of the chassis frame 1, and an eccentric drive mechanism disposed within the chassis frame 1 for driving the stepping brackets to move. The stepping brackets are rotatably engaged with the drive end of the eccentric drive mechanism. The stepping brackets include a bottom support plate 3 located below for contacting the mortar surface to provide support, and a side support plate 4 fixed on the plate surface of the bottom support plate 3 for engaging with the drive end of the eccentric drive mechanism. A rotating shaft 5 is passed through the side support plate 4, and the end of the rotating shaft 5 is fixedly connected to the eccentric drive mechanism. The side support plate 4 is rotatably engaged with the rotating shaft 5.

[0030] The stepping mechanism uses the bottom support plate 3 to increase the contact area with the mortar surface, thereby reducing damage to the mortar surface during chassis movement. At the same time, the eccentric drive mechanism drives the chassis, and the movement distance of the chassis can be controlled by controlling the eccentric distance, so that the leveling track can accurately cover the gap area between the original tracks.

[0031] Specifically, the eccentric drive mechanism of the present invention includes a motor 6, a drive gear 7, an eccentric arm 8, and a gear shaft 9 fixedly connected to the eccentric arm 8. The eccentric arm 8 is rotatably engaged with the chassis frame 1, and the gear shaft 9 is engaged with the drive gear 7 fixed at the rotating end of the motor 6. The motor 6 drives the gear shaft 9 and the eccentric arm 8 to rotate. The connection positions of the gear shaft 9 and the rotating shaft 5 with the eccentric arm 8 are staggered, and the step movement length is controlled by the staggered distance.

[0032] Preferably, the present invention has four eccentric arms 8, arranged symmetrically in pairs about the chassis frame 1. One pair is connected to the end of the gear shaft 9 and is directly driven by the gear shaft 9. The other pair of eccentric arms 8 is driven to rotate synchronously with the eccentric arms connected to the end of the gear shaft through a sprocket mechanism, thereby ensuring the stability of the chassis support during the step movement. The sprocket mechanism includes a sprocket 14 and a transmission chain 15. The sprocket 14 is fixed concentrically with the rotation center of the eccentric arm 8.

[0033] During the stepping movement, the eccentric arm 8 has a first position and a second position before and after the stepping mechanism moves. At the first position, the rotating shaft 5 is located at the rear end of the rotation center of the eccentric arm 8, and the stepping mechanism is suspended in the air by the eccentric arm 8. At the second position, the rotating shaft 5 moves to the front end of the rotation center of the eccentric arm as the eccentric arm rotates, and the bottom of the stepping mechanism contacts the mortar surface. When the eccentric arm 8 continues to rotate, the stepping mechanism provides support force, and the chassis frame 1 rotates around the rotating shaft 5 with the eccentric arm 8, so that the chassis frame 1 moves forward as a whole.

[0034] This invention discloses a leveling device. Using the aforementioned leveling chassis structure, existing mortar cleaning equipment can be mounted on the chassis of this invention to achieve the leveling function of the mortar surface. The device remains within the scope of protection of this invention regardless of the type of mortar cleaning equipment used. In embodiments of this invention, to ensure leveling accuracy, the leveling device includes a spiral auger movably mounted on the chassis frame 1. The spiral auger has a horizontal degree of freedom parallel to the leveling track driving the chassis frame and a vertical degree of freedom to move perpendicular to the mortar surface. The height of the leveling surface is controlled by controlling the height of the spiral auger. Preferably, the spiral auger is a single-auger structure to ensure the consistency of the surface height after mortar cleaning. The lifting and lowering movement of the spiral auger can be achieved using a screw lifting component. Horizontal movement can be achieved using a guide rail in conjunction with a corresponding drive cylinder or electric push rod. The screw lifting component needs to be installed as a whole on the drive end of the drive cylinder or electric push rod to enable left and right movement.

[0035] This invention discloses a method of using the above-mentioned leveling device. The leveling track is driven by a drive structure to rotate, so that the entire leveling device moves horizontally on the mortar. The leveling track flattens the mortar on the moving path. At the same time, the spiral auger rotates to clear the next leveling area in front of the leveling device and pushes the excess mortar forward. After the mortar leveling of the current moving path is completed, the stepping mechanism drives the entire leveling device to move to the next leveling area and perform mortar leveling again.

[0036] When the leveling device moves as a whole via the stepping mechanism, the two sets of leveling tracks are divided into a first leveling track and a second leveling track along the direction of movement of the leveling device driven by the stepping mechanism. After the leveling device moves, the second leveling track covers the gap area between the first leveling track and the second leveling track before the movement, and the first leveling track covers the leveling area cleaned by the spiral auger.

[0037] The specific action process is as follows: Figure 2 and Figure 3 As shown, Figure 2 With the eccentric arm 8 in the first position, as shown in the diagram, when the leveling device needs to move forward, the leveling device remains stationary. The gear shaft 9 drives the eccentric arm 8 to rotate counterclockwise. During the rotation, due to the rotational engagement between the side support plate 4 and the eccentric arm 8 via the rotating shaft 5, the eccentric arm 8 rotates to... Figure 3 In the second position shown, the bottom support plate 3 of the stepping mechanism contacts the mortar surface, and then the gear shaft 9 continues to drive the eccentric arm 8 to rotate. During this process, the stepping mechanism provides support for the entire chassis of the leveling device, allowing the chassis to move forward and complete a movement equidistant from the eccentric distance. After completing the stepping movement, the eccentric arm 8 continues to rotate to the first position, lifting the stepping mechanism and causing the bottom support plate 3 to detach from the mortar surface. The leveling device can then continue to perform the next round of leveling operations. When it is necessary to retreat, the gear shaft 9 can be rotated in the opposite direction according to the same principle.

[0038] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
