Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete construction technology, and in particular to a concrete leveling mechanism and a leveling machine having the same. Background Technology
[0002] Currently, roller screeds are commonly used for leveling concrete pavements, mostly three-roller screeds that combine lifting, compaction, and leveling functions. However, poor leveling quality still exists during the process, such as wavy surfaces and uneven mortar. Furthermore, stopping midway creates a stop groove, leaving a section of the machine unusable at the starting point. Therefore, it is necessary to improve existing concrete screeds. Based on experience in concrete pavement construction, the applicant has developed a machine that provides better leveling quality and avoids the stop groove and the problem of an unusable starting section. Summary of the Invention
[0003] Therefore, based on the above background, this utility model improves upon existing technology and provides a concrete leveling mechanism and a leveling machine thereof. Through the reasonable arrangement of spiral roller shaft, leveling roller shaft, lifting roller shaft, and vibrating trowel plate, it can avoid uneven mortar and the appearance of wavy surface, improve leveling quality, and avoid the problem of stopping grooves and the inability to level a certain position of the machine body at the beginning of the construction.
[0004] This utility model is achieved through the following technical solution:
[0005] A concrete leveling mechanism includes a suspension having a length, and a leveling assembly adapted to be mounted on the suspension, the leveling assembly comprising:
[0006] A spiral roller shaft includes a first shaft body, a left propeller blade is provided on the left section of the shaft body, and a right propeller blade is provided on the right section, wherein the left propeller blade and the right propeller blade rotate in opposite directions;
[0007] Leveling roller, including a second shaft body;
[0008] The lifting roller shaft includes a third shaft body;
[0009] A vibrating rubbing plate includes a plate body and a rotary drive mechanism. The plate body can be flipped up and down and installed on the rear side of the suspension via the rotary drive mechanism. The plate body includes a flat plate, which can be rotated to a horizontal state under the drive of the rotary drive mechanism. A vibrating motor is installed on the flat plate.
[0010] The spiral roller shaft, leveling roller shaft, and lifting roller shaft are rotatably mounted on the bottom of the suspension.
[0011] The spiral roller shaft, leveling roller shaft, lifting roller shaft, and vibrating rubbing plate are arranged in sequence from front to back;
[0012] The drive mechanism drives the spiral roller shaft, the leveling roller shaft, and the lifting roller shaft to rotate.
[0013] One implementation is that the driving mechanism includes a first driving mechanism and a second driving mechanism. The first driving mechanism drives the spiral roller shaft and the leveling roller shaft to rotate through a first transmission mechanism, and the second driving mechanism drives the lifting roller shaft to rotate through a second transmission mechanism.
[0014] One implementation involves the first drive mechanism and the second drive mechanism being located at opposite ends of the suspension.
[0015] One implementation involves mounting the two ends of the spiral roller shaft, leveling roller shaft, and lifting roller shaft rotatably onto the suspension frame via bearing seats.
[0016] One implementation involves rotatably mounting the two ends of the spiral roller shaft, leveling roller shaft, and lifting roller shaft onto the suspension via an adjustment assembly. The adjustment assembly includes an outer box with a lower opening, a lifting box located within the cavity of the outer box, and a lifting adjustment screw. The outer box can be appropriately fixed to the frame of the suspension.
[0017] The lifting box can move up and down along the outer box body;
[0018] Part of the lifting and adjusting screw can rotatably pass through the upper box plate of the outer box via a bearing;
[0019] The lower part of the lifting adjustment screw is connected to the lifting box by a threaded connection;
[0020] The lower box plate of the lifting box is equipped with bearings with seats that are respectively connected to the two ends of the spiral roller shaft, the leveling roller shaft, and the lifting roller shaft 4.
[0021] One implementation is that the rotary drive mechanism includes an electric telescopic rod.
[0022] One implementation method is that the height of the vibrating rubbing plate can be adjusted by a connecting component.
[0023] Based on the same inventive concept, the present invention also provides a concrete leveling machine, which includes a walking mechanism and the aforementioned concrete leveling mechanism.
[0024] The walking mechanism includes walking wheels, a walking drive mechanism, and a wheel frame. The walking drive mechanism drives the walking wheels to move through the walking transmission mechanism, and the suspension of the concrete leveling mechanism is mounted on the wheel frame.
[0025] One implementation involves mounting the suspension to the wheel frame in a height-adjustable manner via a lifting assembly.
[0026] One implementation is that the lifting assembly includes a lifting mechanism and a guide fixing assembly. The guide fixing assembly includes a guide rod fixed to the wheel frame and a guide sleeve fixed to the suspension. The guide rod passes through the guide sleeve.
[0027] The lifting assembly includes a vertical electric push rod, which is mounted on a wheel frame and its rod body can be appropriately fixed to the suspension.
[0028] The beneficial effects of adopting the above technical solution are as follows:
[0029] Compared with existing technologies, this utility model uses a spiral roller, a leveling roller, and a lifting roller arranged in sequence to spread the concrete, perform initial leveling and compaction, and then compact it again. Finally, a vibrating screed plate is used to increase the density and flatness of the concrete surface by combining the vibration of the vibrating motor with the plate. This can ultimately avoid the appearance of a wavy surface and improve the leveling quality. Furthermore, the reasonable arrangement of the spiral roller, leveling roller, lifting roller, and vibrating screed plate can avoid the problem of stopping the machine and being unable to level the initial position of the machine.
[0030] The spiral roller shaft uses propeller blades with opposite ends to spread the concrete when rotating, while maintaining the balance of aggregate. Compared with unidirectional propeller blades, it can avoid the concrete from concentrating on both sides and avoid the impact on the bearings at both ends.
[0031] This invention offers greater flexibility in use. The tilt angle or height of the spiral roller, leveling roller, and lifting roller can be adjusted via fine-tuning through the adjustment components, allowing them to better adapt to road surfaces with different tilt angles or heights. Furthermore, the suspension of the leveling machine can be raised and lowered on the wheel frame via the lifting components, and the height of the leveling components can be adjusted by raising and lowering the suspension as a whole, further enhancing its flexibility in use.
[0032] This invention uses a rotary drive mechanism to rotate and flip the vibratory trowel plate to adapt to different construction conditions. For example, when the concrete is not leveled, the plate is controlled to flip upwards for folding; when leveling is required, it is flipped downwards to make the plate horizontal.

[0053] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0054] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "inner," "outer," "vertical," "circumferential," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0055] In the description of this utility model, "first feature" and "second feature" may include one or more of the indicated features. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the indicated features.
[0056] The following is in conjunction with the appendix Figures 1 to 19 The present invention will be further described below.
[0057] In the embodiments, unless otherwise specified, all connections involving fixed connections are made by welding or using bolts for fixed connection.
[0058] Example 1: According to the appendix Figure 1 To be continued Figure 13 The concrete leveling mechanism shown includes a suspension 1 having a length, and a leveling assembly adapted to be mounted on the suspension 1, the leveling assembly comprising:
[0059] The spiral roller shaft 2 includes a first shaft body 21, with a left propeller blade 22 on the left section and a right propeller blade 23 on the right section, the left propeller blade 22 and the right propeller blade 23 rotating in opposite directions;
[0060] The leveling roller 3 includes a second shaft body 31;
[0061] The lifting roller shaft 4 includes a third shaft body 41;
[0062] like Figure 11 As shown, the second shaft 31 and the third shaft 41 are optical rods.
[0063] The vibrating rubbing plate 5 includes a plate body and a rotary drive mechanism. The plate body is rotatably mounted on the rear side of the suspension 1 via the rotary drive mechanism. The plate body includes a plate 51, which can be rotated to a horizontal state under the drive of the rotary drive mechanism. A vibrating motor 54 is mounted on the plate 51.
[0064] The spiral roller shaft 2, leveling roller shaft 3, and lifting roller shaft 4 are rotatably mounted on the bottom of the suspension.
[0065] The spiral roller 2, leveling roller 3, lifting roller 4, and vibrating screed 5 are arranged sequentially from front to back (in the direction of construction progress), as follows: Figure 2 As shown, in specific implementation, the leveling mechanism of this embodiment is installed in the leveling machine. When leveling concrete along the direction of the leveling machine's movement, the concrete is first spread out by the propeller blades of the spiral roller 2, then initially leveled and compacted by the leveling roller 3, then compacted again by the lifting roller 4, and finally the concrete surface density and smoothness are increased by the vibration of the vibrating motor and the cooperation of the plate, ultimately avoiding the appearance of a wavy surface and improving the leveling quality. This invention uses left-right reversing propeller blades, which can maintain aggregate balance while spreading the concrete. Compared to unidirectional propeller blades, this avoids the concrete concentrating on both sides, preventing impact on the bearings at both ends.
[0066] The drive mechanism drives the spiral roller shaft 2, the leveling roller shaft 3, and the lifting roller shaft 4 to rotate.
[0067] Specifically, such as Figures 11 to 13As shown, the driving mechanism includes a first driving mechanism 6 and a second driving mechanism 7. The first driving mechanism 6 drives the spiral roller shaft 2 and the leveling roller shaft 3 to rotate through a first transmission mechanism, and the second driving mechanism 7 drives the lifting roller shaft 4 to rotate through a second transmission mechanism.
[0068] In some embodiments, preferably, the first drive mechanism and the second drive mechanism are located at both ends of the suspension 1.
[0069] The two ends of the spiral roller shaft 2, leveling roller shaft 3, and lifting roller shaft 4 are respectively rotatably mounted on the frame of the suspension 1 via seated bearings 8 (not shown, this is common knowledge; specifically, the seated bearings 8 connected to the two ends of the spiral roller shaft 2, leveling roller shaft 3, and lifting roller shaft 4 can be appropriately mounted on the horizontal frame of the suspension via bolts).
[0070] like Figure 12 As shown, the first drive mechanism 6 includes a first drive motor, and the first transmission mechanism includes a first belt drive mechanism 62, a first chain drive mechanism 65, a second chain drive mechanism 66, and a third chain drive mechanism 67. One pulley of the first belt drive mechanism 62 is fixedly connected to the drive shaft of the first motor, and the other pulley is fixedly connected to the end of the first driven shaft 63. One sprocket of the first chain drive mechanism 65 is fixedly sleeved at the middle position of the first driven shaft 63, and the other sprocket is fixedly sleeved at the middle position of the second driven wheel 64. One sprocket of the second chain drive mechanism 66 is fixedly sleeved at the end of the first driven shaft away from the pulley, and the other sprocket is fixedly sleeved at one end of the leveling roller shaft 3. One sprocket of the third chain drive mechanism 67 is fixedly sleeved at the end of the second driven shaft, and the other sprocket is fixedly sleeved at one end of the spiral roller shaft 2. The first driven shaft and the second driven shaft are rotatably mounted on the frame of the suspension 1 through a bearing 8.
[0071] like Figure 13 As shown, the second drive mechanism 7 includes a second motor, and the second transmission mechanism includes a second belt drive mechanism 72 and a fourth chain drive mechanism 74. One of the pulleys of the second belt drive mechanism is fixedly connected to the drive shaft of the second motor, and the other pulley is fixedly sleeved on the end of the third driven shaft 73. One of the sprockets of the fourth chain drive mechanism 71 is fixedly sleeved on the end of the third driven shaft 73 away from the pulley, and the other sprocket is fixedly sleeved on the end of the lift roller shaft 4.
[0072] In practical applications, the spiral roller shaft 2, the leveling roller shaft 3, and the lifting roller shaft 4 each extend a connecting rod with an outer diameter smaller than the shaft body at both ends. The spiral roller shaft 2, the leveling roller shaft 3, and the lifting roller shaft 4 are connected to the corresponding sprockets through the connecting rods.
[0073] The rotary drive mechanism includes an electric telescopic rod 53. Preferably, the rotary drive mechanism includes an electric hydraulic push rod, the rod of which is rotatably mounted on the flat plate. In specific applications, the rotation of the vibrating washboard can be controlled by controlling the extension and retraction of the electric telescopic rod to adapt to different construction conditions. For example, when performing uneven concrete construction, the flat plate is controlled to tilt upwards for folding; when leveling is required, it is tilted downwards to bring the flat plate to a horizontal position, thereby improving its flexibility of use.
[0074] There may be other embodiments, such as Figures 6 to 10 As shown, the height of the vibrating scrubbing plate 5 can be adjusted by the connecting assembly. The connecting assembly includes a first connecting assembly for connecting the suspension and the rotary drive mechanism, and a second connecting assembly for connecting the suspension and the connecting support plate. The first connecting assembly includes a first base plate 531, which has four vertically extending first slots 5311. A top plate 534 is located below the first base plate, and a first guide plate 533 is located below the top plate 534. A through screw hole is opened on the first guide plate 533, and a first screw is threaded into the first screw hole. The top of the first screw abuts against the top plate 534. The first base plate is installed on the suspension by pressing the fixing screw through the first slots 5311. In specific implementation, the top of the first screw may abut against the bottom of the first base plate. The second connecting assembly includes a second base plate 521, on which a second slot 5211 is provided. A second guide plate 5214 is provided below the second base plate 521, on which a second screw hole is opened. A second screw is threaded into the second screw hole. The head of the first screw abuts against the second base plate. The second base plate is installed on the suspension by pressing the fixing screw through the second slot 5211. A connecting support plate 52 is rotatably mounted on the second base plate. The other end of the connecting support plate is rotatably mounted on the vibrating scrubbing plate.
[0075] The first connecting component and the second connecting component work together to adjust the height of the vibrating washboard. Specifically, by loosening the fixing screws on the first base plate and the second base plate, the first screw head and the second screw are rotated upward or downward, and the fixing screws move along the first slot and the second slot respectively until the top of the first screw head and the second screw head abut against the first base plate or top plate and the second base plate. Then the fixing screws are tightened to secure the first base plate and the second fixing screw, so that the rotating mechanism and the vibrating washboard can be adjusted up and down.
[0076] Example 2: Combined with Appendix Figure 1 To be continued Figure 16The concrete leveling mechanism shown in this embodiment, compared to embodiment 1, has its two ends of the spiral roller 2, leveling roller 3, and lifting roller 4 rotatably mounted on the suspension 1 via adjusting components 9. That is, the number of adjusting components 9 is 6.
[0077] Specifically, such as Figures 14 to 16 As shown, the adjustment assembly 9 includes an outer box 91 with a lower opening, a lifting box 92 located inside the box cavity of the outer box 91, and a lifting adjustment screw 93; the outer box 91 can be adapted to be fixed to the frame rod of the suspension 1; the lifting box 92 can move up and down along the box body of the outer box 91; part of the lifting adjustment screw 93 rotatably passes through the upper box plate of the outer box 91 through a bearing; the lower part of the lifting adjustment screw 93 is connected to the lifting box 92 by a threaded connection; the lower box plate of the lifting box 92 is provided with seated bearings 8 that are respectively connected to the two ends of the spiral roller shaft 2, the leveling roller shaft 3, and the lifting roller shaft 4.
[0078] Specifically, the top of the lifting adjustment screw 93 is equipped with a handwheel 94. When the handwheel is rotated 1 / 4 turn, the corresponding roller shaft is raised or lowered by 1 mm. In actual application, the lifting adjustment screw 93 has a threaded section, and the top of the lifting box 92 is equipped with a threaded hole. The threaded section and the threaded hole are screwed together.
[0079] In this embodiment, by adjusting the lifting adjustment screw in the adjustment assembly to rotate upward or downward in the threaded hole, the angle or height of the spiral roller shaft 2, the leveling roller shaft 3, and the lifting roller shaft 4 can be finely adjusted to adapt to different road surfaces.
[0080] In practical applications, when the roller shaft is raised or lowered by rotating the handwheel, the final angle of the handwheel rotation (from the initial angle of installation to the final angle) will not exceed 360 degrees, that is, the final lifting height of the corresponding roller shaft will not exceed 4mm.
[0081] When adjusting the angle of the corresponding roller, it can be done by controlling one end of the roller to rise or fall by controlling the handwheel, or by rotating both ends of the roller to raise or lower it to different heights.
[0082] Example 3: Combined with Appendix Figure 1 To be continued Figure 19 The concrete leveling machine shown includes a walking mechanism 100 and a concrete leveling mechanism as described in Embodiment 1 or Embodiment 3.
[0083] The walking mechanism 100 includes four walking wheels 102, a walking drive mechanism 103 corresponding to the four walking wheels, and a wheel frame 101. The walking drive mechanism drives the walking wheels to move through the walking transmission mechanism 104. The suspension of the concrete leveling mechanism is mounted on the wheel frame.
[0084] like Figure 17 and 18 As shown, the walking drive mechanism includes a walking drive motor, the walking transmission mechanism is a conventional chain mechanism, the walking wheel cover is located below the wheel frame, the drive shaft of the walking drive motor is connected to one sprocket of the chain transmission mechanism, and the other sprocket is fixedly sleeved on one end of the drive shaft. The drive shaft is rotatably mounted on the wheel frame through bearings, and the walking drive mechanism drives the drive shaft to move the walking wheel through the walking transmission mechanism 104. This is conventional technology and will not be described further.
[0085] The suspension is flexibly mounted on the wheel frame via a lifting assembly. The lifting assembly includes a lifting mechanism 110 and a guide fixing assembly. The guide fixing assembly includes a guide rod 120 fixed to the wheel frame and a guide sleeve 130 fixed to the suspension, with the guide rod passing through the guide sleeve. The lifting assembly also includes a vertical electric push rod, preferably a hydraulic electric push rod, mounted on the wheel frame, with its rod body appropriately fixed to the suspension. As shown in the figure, fixed plates extend from both ends of the suspension, and the rod body is fixed to the fixed plates.
[0086] In this embodiment, the entire structure moves up and down via a suspension system, and the vibrating screed plate is flipped in conjunction with a rotary drive mechanism. This avoids grooves caused when the machine stops. Furthermore, by placing the spiral roller shaft 2, leveling roller shaft 3, and lifting roller shaft 4 at the lower part of the suspension system, and placing the vibrating screed plate at the rear side of the suspension system, the problem of not being able to level the machine at the beginning of the construction can be avoided.
[0087] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
