Technical Field

[0001] The present invention relates to the technical field of road leveling devices, and in particular to a road leveling device for municipal road construction and a use method thereof. Background Art

[0002] Depending on the pavement material, roads are divided into cement pavements and asphalt pavements. Cement pavement refers to a pavement with cement and gravel as the main materials for the surface layer, referred to as cement pavement.

[0003] In the prior art, most road leveling devices only use rollers to level the road surface. When the road surface has serious gravel protrusions, the rollers will be unable to level the road surface. Summary of the invention

[0004] In view of the deficiencies in the prior art, the object of the present invention is to provide a road paving device for municipal road construction and a method of using the same, so as to solve the above problems.

[0005] In view of this, the present invention provides a road paving device for municipal road construction, comprising:

[0006] Job Board;

[0007] Two rolling structures are arranged on both sides of the bottom end of the working plate;

[0008] A push-flattening device is arranged at the bottom end of the working plate, and the push-flattening device is located between the two rolling mechanisms;

[0009] and a filling device, the fixed end of which is arranged on the working plate, and the output end of which passes through the working plate and the bottom end of the pushing device;

[0010] The rolling structure is used to perform preliminary rolling of the road construction, the flattening device is used to perform detailed flattening of the preliminary flattened road, and the filling device is used to fill the road while the flattening device is flattening, thereby achieving a smooth road surface.

[0011] By adopting the above technical solution, the filling device is first started to complete the cement production, and then the rolling structure and the flattening device are started. The rolling structure first rolls and flattens the cement road surface for the first time. When the flattening device contacts the road surface flattened by the first rolling, a second detailed flattening is performed. Under the action of the filling device, when gaps appear in the cement road, cement is filled in the gaps, thereby achieving the flatness of the cement road surface. Subsequently, another rolling structure is used to perform a second rolling and flattening, thereby achieving the optimal flatness of the cement road surface.

[0012] In the above technical solution, the further rolling structure includes:

[0013] Two support plates are arranged on both sides of the bottom end of the working plate;

[0014] A pressure roller, rotatably connected between the two support plates; and a drive motor, disposed on the top of the working plate;

[0015] Wherein, each of the driving motors is connected to the two roller belts of the two flattening structures, and a protective plate is provided outside the belt connection.

[0016] In the present technical solution, by setting the driving motor, both pressure rollers can be rotated, thereby achieving double rolling flattening, and by setting the protective plate, the belt transmission can be made more stable.

[0017] In the above technical solution, the further bulldozing device includes:

[0018] A first hydraulic cylinder, with a fixed end disposed at the bottom end of the working plate and an output end facing vertically toward the ground;

[0019] A push plate, arranged on the output end of the first hydraulic cylinder;

[0020] A push-flattening structure is arranged at the bottom end of the push plate;

[0021] and a vibration structure, the fixed end of which is arranged at the bottom end of the push plate, and the output end cooperates with the push-leveling structure;

[0022] The vibration structure is used to soften the uneven construction ground by vibration, and then the flattening structure is used to flatten it.

[0023] In the present technical solution, the push plate can be raised and lowered by the setting of the first hydraulic cylinder, and the cement road surface can be softened by the setting of the vibration structure, so that the leveling structure can level the road surface more thoroughly.

[0024] In the above technical solution, the further flattening structure includes:

[0025] A connecting rod, one end of which is arranged at the bottom end of the push plate, and the other end of which extends toward the ground;

[0026] A push plate, the push plate comprising a fixed plate and a movable plate, the fixed plate being fixedly connected to an end of the connecting rod away from the push plate, and the movable plate being rotatably connected to an end of the connecting rod away from the push plate;

[0027] and an elastic component, the elastic component comprising a hollow arc rod arranged on the side wall of the push rod, an arc plug rod with one end arranged on the top of the movable plate and the other end inserted into the hollow arc rod, and an elastic member arranged in the hollow arc rod;

[0028] Among them, the movable plate and the fixed plate are respectively located on both sides of one end of the connecting rod, and the movable plate is located on the side where the flattening structure moves forward. The side of the movable plate away from the fixed plate is an inclined surface with an inclined surface facing upward. In the initial state, the movable plate and the fixed plate are parallel to the ground.

[0029] In the technical solution, by setting the connecting rod, the fixed plate and the movable plate can be lowered at the same time. By cooperating with the hollow arc rod, the arc plug rod and the elastic member, the movable plate can be restored to a horizontal position by the elastic force when there is no upward pressure.

[0030] In the above technical solution, the vibration structure further comprises:

[0031] A plurality of second hydraulic cylinders, fixed ends of which are arranged in a row at the bottom end of the push plate, and movable ends of which face the movable plate;

[0032] A plurality of vibration generators are arranged on the output end of the second hydraulic cylinder;

[0033] A plurality of cement vibration rods, the input ends of which are connected to the output ends of the vibration generator, and the output ends of which extend into the movable plate;

[0034] A hollow insert plate, one end of which is arranged at the bottom end of the push plate, and the other end of which extends toward the movable plate;

[0035] An insert plate, one end of which is rotatably connected to the movable plate, and the other end of which extends into the hollow insert plate;

[0036] L-shaped plate, one end of which is connected to the plug-in plate, and the other end is parallel to the cement vibrator;

[0037] A plurality of springs, one end of which is connected to the L-shaped plate, and the other end of which is connected to the cement vibrating rods respectively;

[0038] and a contact switch, which is arranged in the hollow plugboard;

[0039] Wherein, the movable plate is provided with a through hole for the cement vibration rod to pass through, and when the movable plate rotates upward, the insertion plate rises and touches the contact switch, and the second hydraulic cylinder and the vibration generator are started simultaneously.

[0040] In the present technical solution, when the pressure roller cannot flatten the protruding gravel, when the movable plate touches the uneven gravel, the movable plate rotates upward and the insert plate moves upward. When the movable plate rotates too much, it continues to move into the hollow insert plate, and the insert plate touches the contact switch. At this time, the drive motor stops working, the output end of the second hydraulic cylinder drops, and the vibration generator is started at the same time. When the cement vibrating rod drops and the insert plate rises, the elastic part on the L-shaped plate pulls the cement vibrating rod to bend toward the bottom of the movable plate. When the cement vibrating rod touches the uneven cement surface, it continues to vibrate, thereby softening the cement pavement. When the cement surface softens, the drive motor starts, the output end of the second hydraulic cylinder rises, and the pressure roller continues to move forward. At this time, the fixed plate flattens the cement pavement, and the elastic component rebounds the movable plate. At this time, the uneven gravel cement pavement will be flattened.

[0041] In the above technical solution, the packing device further comprises:

[0042] A mixing drum is arranged on the top of the working plate, and a drum cover is provided on the top of the mixing drum;

[0043] Two oscillating components are nested in the two side walls of the mixing drum;

[0045] And a number of output hoses, one end of which is evenly connected to the bottom of the mixing drum, and the other end passes through the working plate and the movable plate;

[0046] Among them, mounting holes for placing the oscillation assembly are provided on both sides of the mixing drum, an elastic sealing cloth is provided at the inner opening of the mounting hole, and the middle part of the elastic sealing cloth is fixedly connected to the mixing assembly. The oscillation assembly can make the cement mixed by the mixing assembly better, and a cement valve is provided on the output hose.

[0047] In the present technical solution, by setting up the mixing barrel, the materials for cement manufacturing can be put in; by setting up the oscillation component, the frequency and amplitude of the mixing component can be changed within a certain band so as to achieve more uniform mixing of the materials; by setting up the output hose and the cement valve, the cement can be controlled to move to the bottom of the movable plate; by setting up the elastic sealing cloth, the mixing component can be moved up, down, left and right, and the elastic sealing cloth will not leak materials.

[0048] In the above technical solution, the oscillating component further comprises:

[0049] The rotating bearings are respectively sleeved on the stirring components;

[0050] A plurality of force-bearing blocks are respectively arranged circumferentially on the inner walls of the two mounting holes;

[0051] and a plurality of second elastic members, one end of which is connected to the outer side wall of the rotating bearing, and the other end of which is respectively connected to the force bearing blocks;

[0052] Wherein, a plurality of the second elastic members are circumferentially arranged on the outer side wall of the rotating bearing.

[0053] In the present technical solution, through the cooperation between the force-bearing block and the second elastic member, the rotating bearing can swing in a vertical plane and be subjected to elastic force. Then, the material is subjected to uneven force through the stirring component, thereby achieving displacement of the vertical plane of the stirring rod. The stirring component can drive the material to a position where the material is mixed more evenly and fully, and the air content is increased.

[0054] In the above technical solution, the stirring assembly further comprises:

[0055] The driving shaft has two ends which are rotatably connected to two rotating bearings respectively;

[0056] A flexible shaft connected to the driving shaft and located outside the mixing drum;

[0057] Drive the motor, and the output end is fixedly connected to the rotating shaft;

[0058] and a plurality of stirring rods evenly distributed on the outer side wall of the driving shaft;

[0059] The driving motor drives the flexible shaft to rotate, and the flexible shaft drives the driving shaft to rotate, so that the plurality of stirring rods stir.

[0060] In the technical solution, by setting the flexible shaft, the driving motor can still drive the driving shaft to rotate normally when the driving shaft shakes, and by setting the stirring rod, the cement material can be better stirred.

[0061] In the above technical solution, the following steps are further included:

[0062] S1: First, start the filling device to mix the cement, then start the first hydraulic cylinder, and when the movable plate and the fixed plate are in contact with the ground, start the driving motor to rotate the pressure roller;

[0063] S2: Start the cement valve, the pressure roller flattens the cement pavement, the movable plate and the fixed plate smooth the cement pavement, and the cement discharged from the output hose fills the cement pavement;

[0064] S3: When the crushed stone protrudes, the roller cannot flatten it. When the movable plate touches the uneven crushed stone, the movable plate rotates upward and the insert plate moves upward. When the movable plate rotates too much, the insert plate touches the contact switch, the drive motor stops working, the output end of the second hydraulic cylinder drops, and the vibration generator is started at the same time. When the cement vibration rod drops and the insert plate rises, the elastic member on the L-shaped plate pulls the cement vibration rod to bend toward the bottom of the movable plate. When the cement vibration rod touches the uneven cement surface, it continues to vibrate, thereby softening the cement road surface.

[0065] S4: When the cement surface softens, the drive motor starts, the output end of the second hydraulic cylinder rises, and the pressure roller continues to move forward. At this time, the fixed plate flattens the cement road surface, and the elastic component rebounds the movable plate. At this time, the uneven gravel cement road surface will be flattened;

[0066] S5: Complete the leveling of all road sections and fill them with cement.

[0067] In the present technical solution, by setting S1, the cement in the filling device can be used, and the cement road surface can be flattened and leveled simultaneously; by setting S2, the gaps between the stones can be filled after the pressure rollers flatten the road surface; by setting S3, the uneven cement road surface can be softened, so that the fixed plate can level the road surface; and by setting S4, the movable plate can return to its original position for the next softening and leveling.

[0070] 2. Through the setting of the filling device, the gaps in the cement pavement can be filled. BRIEF DESCRIPTION OF THE DRAWINGS

When the cement vibration rod 14 drops and the insert plate 16 rises, the elastic member on the L-shaped plate 17 pulls the cement vibration rod 14 to bend toward the bottom of the movable plate 8. When the cement vibration rod 14 touches the uneven cement surface, it continues to vibrate, thereby softening the cement road surface;

[0147] S4: When the cement surface softens, the drive motor 4 starts, the output end of the second hydraulic cylinder 12 rises, and the pressing roller 3 continues to move forward. At this time, the fixed plate 9 flattens the cement road surface, and the elastic component rebounds the movable plate 8. At this time, the uneven gravel cement road surface will be flattened;

[0148] S5: Complete the leveling of all road sections and fill them with cement;

[0149] By setting S1, the cement in the filling device can be used, and the cement road surface can be flattened and leveled at the same time. By setting S2, the gaps between the stones can be filled after the pressure roller 3 flattens the road surface. By setting S3, the uneven cement road surface can be softened, so that the fixed plate 9 can level the road surface. By setting S4, the movable plate 8 can return to its original position for the next softening and leveling.
