[0040] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0041] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present application, rather than all of the embodiments.

[0042] The roadbed construction device and construction method of the embodiment of the present application are described below with reference to the accompanying drawings.

[0043] like Figure 1 , Figure 2 and Figure 3 As shown, the roadbed construction device of the first embodiment of the present application may include a crossbeam 1, a traction frame 2, a connecting frame 3, a swing cutting assembly 4 and an adjustment mechanism 5.

[0044] The traction frame 2 is arranged on the crossbeam 1 , and the traction frame 2 is used to be connected with an external traction device.

[0045] It should be noted that two traction heads are symmetrically arranged on the traction frame 2, and each traction head is provided with symmetrically arranged traction holes. By connecting the traction holes with external traction equipment, the pavement construction device can be towed, and the two external traction equipment can also be respectively connected to the traction holes on the corresponding traction heads, so as to ensure that there is sufficient power to move the pavement construction device. Among them, the external traction equipment can be a tractor, a tractor, etc., which can be selected according to actual conditions.

[0046] The connecting frame 3 is fixed on the crossbeam 1 .

[0047] Furthermore, the connecting frame 3 is designed in a U-shape, and the maintenance cost is relatively low. During use, it is only necessary to regularly check and maintain the surface condition and connection parts of the connecting frame 3 to ensure that it works normally, which helps to reduce the overall maintenance cost and improve economic benefits. In order to further improve the firmness of the connecting frame 3 fixed on the crossbeam 1, the connecting frame 3 can be designed as an integral part with the crossbeam 1.

[0048] As a possible scenario, Figure 8 As shown, in order to further improve the stability of the roadbed construction device during movement, two groups of parallel auxiliary cutting wheels 6 can be detachably connected to the connecting frame 3, and the auxiliary cutting wheels 6 are horizontally arranged relative to the crossbeam 1, wherein the auxiliary cutting wheels 6 are used to support the connecting frame 3, reduce the shaking and tilting of the roadbed construction device, thereby improving the stability of the roadbed construction device during operation, and at the same time, it can also perform squeezing movement to achieve ground breaking during movement.

[0049] It should be noted that the auxiliary cutting wheel 6 described in this embodiment may include a mounting frame 60 and a third cutting wheel 61, and a light hole is opened on the mounting frame 60 to facilitate fixing to the connecting frame 3 through external threaded fasteners, and the third cutting wheel 61 is rotatably connected in the mounting frame 60.

[0050] The swinging soil cutting assembly 4 is hinged to the connecting frame 3, and the swinging soil cutting assembly 4 is connected to an external power source to drive the swinging soil cutting assembly 4 to operate, and is used to cut off the roadbed soil that forms a specified angle with the horizontal plane, wherein the external power source can be a diesel engine, an electric motor, etc., and the installation position and model of the external power source can be selected according to actual conditions.

[0051] The adjusting mechanism 5 is distributed on one side of the connecting frame 3, and one end of the adjusting mechanism 5 is fixedly connected to the crossbeam 1, and the other end of the adjusting mechanism 5 is hinged to the corresponding swing cutting assembly 4. The adjusting mechanism 5 is used to drive the swing cutting assembly 4 to tilt to one side at a specified angle, wherein the specified angle can be specifically set according to the design vehicle speed, terrain conditions, soil type and other conditions of the road.

[0052] Furthermore, it should be noted that the swing cutting assembly 4 and the adjusting mechanism 5 can be set as a group when constructing at a road bend, and when constructing on the inclined sides of the roadbed, the swing cutting assembly 4 and the adjusting mechanism 5 can be set as two groups respectively, which can effectively cope with the complex terrain challenges in road construction and can also achieve a significant improvement in tooling efficiency while ensuring construction quality.

[0053] Specifically, in the actual process of road construction, first, a roller is used to compact the roadbed after horizontal paving to ensure the compactness of the road surface, and then the swinging soil cutting component 4 is driven to tilt to one side at a specified angle through the control and adjustment mechanism 5 to ensure the accuracy of the outward tilt angle of the roadbed, and then the external power source (such as a motor) is started to drive the swinging soil cutting component 4 to operate, and finally the swinging soil cutting component 4 is towed to move by the external traction equipment through the connecting frame 3. During the movement, the swinging soil cutting component 4 is used to cut off the roadbed soil that forms a specified angle with the horizontal plane to form an inclined roadbed surface, so that operations can be carried out directly on the roadbed laid horizontally after being flattened by the roller, which reduces the paving difficulty and can ensure the outward tilt angle of the roadbed, so that the roller does not need to pay special attention to the angle when working, thereby improving the working efficiency of the roller.

[0054] In the process of removing the roadbed soil, it is necessary to regularly check whether the inclination angle of the roadbed and the cutting quality meet the design requirements. If necessary, adjustments can be made through the adjustment mechanism 5 and the external traction equipment to ensure construction accuracy and quality.

[0055] In one embodiment of the present application, Figure 3 As shown, the swing cutting assembly 4 includes a first housing 400 , a driven mechanism 401 and a driving mechanism 402 .

[0056] Among them, one end of the first shell 400 adjacent to the connecting frame 3 is hinged to the connecting frame 3, the adjusting mechanism 5 is hinged to the first shell 400, and a first opening (not marked in the figure) is provided on the side of the first shell 400 away from the adjusting mechanism 5, the driven mechanism 401 is provided in the first shell 400, and part of the driven mechanism 401 is exposed from the first opening, the active mechanism 402 is provided on the first shell 400, and the active mechanism 402 is meshedly connected with the driven mechanism 401, and one end of the active mechanism 402 is connected to an external power source for driving the driven mechanism 401 to rotate.

[0057] Exemplarily, for example, the external power source is a motor, and the motor is disposed on the first housing 400 and connected to one end of the active mechanism 402 via a coupling, so that the active mechanism 402 can be driven to rotate by the motor.

[0058] Specifically, the active mechanism 402 operates to drive the driven mechanism 401 to rotate, thereby cutting the soil below.

[0059] Furthermore, if Figure 4 As shown, the driven mechanism 401 includes a first bearing seat 4010, a first transmission rod 4011, a plurality of first gears 4012 and a plurality of first cutting wheels 4013.

[0060] Among them, the interior of the first shell 400 is fixedly connected with a plurality of first bearing seats 4010 arranged equidistantly along the length direction of the first shell 400, the first transmission rod 4011 is rotatably connected to the plurality of first bearing seats 4010, and the first transmission rod 4011 is alternately provided with a plurality of first gears 4012 and a plurality of first soil cutting wheels 4013, and the plurality of first soil cutting wheels 4013 are horizontally arranged compared to the first shell 400 and partially exposed from the first shell 400, wherein the horizontal arrangement of the first soil cutting wheels 4013 is suitable for roadbed construction with a high middle and low sides, and its cross section presents a downward slope, under this terrain, the horizontally arranged first soil cutting wheels 4013 can better adapt to slope changes, ensure that the thickness of the removed soil layer is uniform, thereby avoiding unevenness during roadbed construction, and because the first soil cutting wheels 4013 are horizontally arranged, the depth and width of the removal can be more accurately controlled when removing the soil, ensuring that the cross-sectional size of the roadbed meets the design requirements.

[0061] As a possible situation, in order to install more first gears 4012 and first cutting wheels 4013 so that the roadbed construction device is evenly stressed, the length of the first cutting wheel 4013 plus the length of the first gear 4012 can be made slightly smaller than the length distance between the two first bearing seats 4010.

[0062] Specifically, when the external power source drives the first gear 4012 to rotate via the active mechanism 402, the first gear 4012 can drive the first cutting wheel 4013 to rotate via the first transmission rod 4011. The first cutting wheel 4013 rotates to cut the roadbed below. Since the adjustment mechanism 5 drives the swing cutting assembly 4 to tilt to one side at a specified angle, this tilting action makes each first cutting wheel 4013 have a different tilt angle, forming an angle gradient. When the multiple first cutting wheels 4013 rotate to cut the roadbed soil, they can act on the roadbed with different cutting depths, thereby cutting off the roadbed soil that forms a specified angle with the horizontal plane, forming an inclined manner in which the roadbed is high in the middle and low on both sides.

[0063] Furthermore, if Figure 4 As shown, the active mechanism 402 includes a second bearing seat 4020 , a second transmission rod 4021 and a second gear 4022 .

[0064] Among them, the first shell 400 is fixedly connected to a plurality of second bearing seats 4020 arranged equidistantly along the length direction of the first shell 400, the second transmission rod 4021 is rotatably connected to the plurality of second bearing seats 4020, and one end of the second transmission rod 4021 is connected to an external power source, and the second transmission rod 4021 is fixedly connected to a plurality of second gears 4022 arranged equidistantly, a plurality of through holes 4000 are opened on the first shell 400, and parts of the second gears 4022 pass through the corresponding through holes 4000 and engage with the corresponding first gears 4012.

[0065] Specifically, the second transmission rod 4021 can be driven to rotate by an external power source, and when the second transmission rod 4021 rotates, it drives the first gear 4012 to rotate via the second gear 4022, thereby driving the first cutting wheel 4013 to rotate.

[0066] In one embodiment of the present application, Figure 4 As shown, two groups of driven mechanisms 401 and active mechanisms 402 are respectively provided, and the first cutting wheels 4013 in one group of driven mechanisms 401 are staggered with the first cutting wheels 4013 in the other group of driven mechanisms 401 to ensure that each position can be cut.

[0067] Among them, the staggered arrangement of the first cutting wheel 4013 can ensure that most positions of the roadbed can be effectively cut, avoiding uneven cutting or uncut areas caused by overlapping or missing positions of the first cutting wheel 4013. This comprehensive coverage design greatly improves the efficiency and quality of roadbed cutting. At the same time, the staggered arrangement helps to reduce interference and repeated cutting during the cutting process. Through the parallel operation of the two sets of driven mechanisms 401 and the active mechanism 402, as well as the staggered arrangement of the first cutting wheel 4013, the construction speed is significantly improved. Compared with a single mechanism or a non-staggered design, this configuration can complete the roadbed cutting task faster and shorten the construction period.

[0068] In another embodiment of the present application, Figure 5 and Figure 6 As shown, the swing cutting assembly 4 includes a second housing 410 , a first sprocket 411 , a second sprocket 412 , a chain 413 and a second cutting wheel 414 .

[0069] Among them, one end of the second shell 410 adjacent to the connecting frame 3 is hinged to the connecting frame 3, the adjusting mechanism 5 and the second shell 410 are hinged, and a second opening is provided on the side of the second shell 410 away from the adjusting mechanism 5, the first sprocket 411 is rotatably connected in the second shell 410, and one end of the first sprocket 411 is exposed to the outside of the second shell 410 and is connected to an external power source, wherein the external power source can be a diesel engine, an electric motor, etc., which can be selected according to actual conditions.

[0070] A plurality of second sprockets 412 and a plurality of second cutting wheels 414 are rotatably connected inside the second shell 410. The second cutting wheels 414 are arranged vertically compared to the second shell 410, and a portion of the second cutting wheels 414 is exposed from the second opening. The first sprocket 411, the second sprocket 412 and the second cutting wheels 414 are connected through a chain 413.

[0071] Among them, the advantage of the vertical arrangement of the second cutting wheel 414 is that the cutting force generated by its rotation directly acts on the land, more effectively penetrating the soil layer and achieving a deeper cutting depth. Compared with the horizontally arranged cutting wheel, the vertically arranged second cutting wheel 414 encounters less resistance during the cutting process, so it can more easily reach a deeper soil layer and achieve a deep cutting depth of the land, which is beneficial to the construction effect of the inner bend being low and the outer bend being high during the curved road construction process, and adapts to complex terrain changes.

[0072] Specifically, an external power source is used to drive the first sprocket 411 to rotate, and the first sprocket 411 cooperates with the chain 413 to simultaneously drive the second sprocket 412 and multiple second cutting wheels 414 to rotate, thereby achieving cutting of the soil below. Since the adjustment mechanism 5 drives the swing cutting assembly 4 to tilt to one side at a specified angle, this tilting action makes each second cutting wheel 414 have a different tilt angle, forming an angle gradient. When the multiple second cutting wheels 414 rotate to cut the roadbed soil, they can act on the roadbed with different cutting depths, thereby cutting off the roadbed soil that forms a specified angle with the horizontal plane, which is suitable for making the inner curve lower than the outer curve roadbed at the curve.

[0073] Furthermore, if Figure 6 As shown, the plurality of second cutting wheels 414 are arranged in a serpentine shape.

[0074] The serpentine arrangement enables the second cutting wheel 414 to form a continuous, staggered cutting path during the cutting process. This arrangement helps to reduce empty cutting and repeated cutting during the cutting process, thereby improving cutting efficiency.

[0075] In order to further clarify the above embodiment, in one embodiment of the present application, Figure 7 As shown, the second cutting wheel 414 includes a square shaft 4140, a third sprocket 4141, a blade mechanism 4142, a rotating shaft 4143 and a bolt 4144.

[0076] Among them, the rotating shaft 4143 is rotatably connected to the inside of the second shell 410, the third sprocket 4141 is fixed on the rotating shaft 4143, and the third sprocket 4141 is meshingly connected with the chain 413, the square shaft 4140 is fixed to the end of the rotating shaft 4143 away from the second shell 410, the blade mechanism 4142 is sleeved on the outer wall of the square shaft 4140, and is fixed to the square shaft 4140 by the bolt 4144, wherein the blade mechanism 4142 can be released by rotating the bolt 4144, thereby facilitating the replacement of the blade mechanism 4142.

[0077] It should be noted that the blade mechanism 4142 described in this embodiment includes a C-shaped tube and a plurality of crushing blades, the plurality of crushing blades are circumferentially fixed at equal angles on the outer wall of the C-shaped tube, and the C-shaped tube is provided with threaded holes that are compatible with the bolts 4144.

[0078] Specifically, when the first sprocket 411 drives the chain 413 to rotate, the chain 413 can also drive the square shaft 4140 to rotate through the third sprocket 4141 in cooperation with the rotating shaft 4143, thereby driving the blade mechanism 4142 to cut the soil.

[0079] In one embodiment of the present application, Figure 2 As shown, the adjustment mechanism 5 includes a first telescopic sleeve 51 and at least one or more second telescopic sleeves 52 .

[0080] Among them, one end of the first telescopic sleeve 51 and the second telescopic sleeve 52 is fixedly connected to the cross beam 1, and the other end of the first telescopic sleeve 51 and the second telescopic sleeve 52 is hinged to the swing cutting assembly 4. The first telescopic sleeve 51 is arranged near the side of the cross beam 1 away from the connecting frame 3. Among them, the first telescopic sleeve 51 and the second telescopic sleeve 52 can be cylinders or electric telescopic cylinders, which can be selected according to actual conditions. By controlling the different telescopic lengths of the first telescopic sleeve 51 and the second telescopic sleeve 52, the swing cutting assembly 4 can be driven to tilt to one side at a specified angle.

[0081] It should be noted that the power of the first telescopic sleeve 51 is greater than that of the second telescopic sleeve 52 , and because it is arranged close to the side of the beam 1 away from the connecting frame 3 , it serves as the main driving source and support.

[0082] Furthermore, in order to facilitate and accurately control the first telescopic sleeve 51 and the second telescopic sleeve 52 to drive the swing cutting assembly 4 to tilt according to a preset angle, the first telescopic sleeve 51 and the second telescopic sleeve 52 can be electrically connected to an external tilt control system, wherein the tilt control system may include a controller, an inclination sensor, etc., which can intelligently detect and correspondingly control the first telescopic sleeve 51 and the second telescopic sleeve 52, thereby improving the accuracy of the tilt angle of the swing cutting assembly 4.

[0083] In one embodiment of the present application, Figure 2 As shown, the above-mentioned roadbed construction device also includes a plurality of limit frames 7, the limit frames 7 are fixed on the cross beam 1, and the swinging soil cutting assembly 4 is arranged in the limit frames 7. The setting of the limit frames 7 can limit the swinging soil cutting assembly 4 to prevent it from excessive or accidental displacement during operation, and effectively reduce the shaking caused by mechanical vibration or external factors, thereby improving the stability and reliability of construction. When the swinging soil cutting assembly 4 cuts the soil, it will encounter resistance and generate a force opposite to the forward direction. At this time, the limit of the limit frame 7 also helps to ensure that the swinging soil cutting assembly 4 remains balanced when subjected to force, avoiding damage caused by local overload or stress concentration.

[0084] The roadbed construction method of the second aspect of the present application is carried out using the roadbed construction device. The construction method specifically includes the following steps:

[0085] Use a roller to compact the roadbed after horizontal paving. According to the type of roadbed filler and compaction requirements, select the appropriate roller model and compaction times to ensure that the roadbed reaches the specified density and stability. The roadbed directly laid horizontally is more convenient and easier to construct.

[0086] The swing cutting assembly 4 is driven to tilt to one side at a specified angle by controlling the adjusting mechanism 5 to meet the construction requirements of the roadbed.

[0087] The external power source is started to drive the swing cutting component 4 to operate.

[0088] The swing cutting assembly 4 is moved by towing via the connecting frame 3 through an external traction device (e.g., a tractor). During the movement, the swing cutting assembly 4 is used to cut off the roadbed soil that forms a specified angle with the horizontal plane, thereby forming a roadbed with an inclination, for example, a roadbed that is higher in the middle and lower on both sides.

[0089] It should be noted that the explanation of the aforementioned roadbed construction device embodiment is also applicable to the construction method of this embodiment, and will not be elaborated here.

[0090] Furthermore, during the process of the swing cutting assembly 4 moving to cut the soil, the loosened loose soil can be cleaned out of the roadbed through the existing cleaning mechanism, which can quickly clean up the loose soil generated during the cutting process to avoid the accumulation of loose soil affecting subsequent construction operations. The cleaning mechanism can be a cleaning vehicle or a loader with cleaning accessories.

[0091] Furthermore, after cleaning by the cleaning mechanism, the cleaned roadbed can be compacted again by a road roller to ensure the compactness of the formed roadbed.
