Description

Technical Field

[0001] The utility model relates to the technical field of road construction leveling, and more specifically, to a municipal road construction leveling device. Background Art

[0002] After the concrete pavement is poured, it is usually necessary to use a leveling device to treat the concrete surface. The concrete surface is leveled through the leveling device, so that the flatness of the road surface meets the design requirements. At the same time, the leveling device can remove the air in the concrete and increase the compactness of the concrete.

[0003] For example, a municipal road construction leveling device disclosed in the patent with the publication number CN210827011U. Although when using this municipal road construction leveling device, the servo motor is started, the linear module is driven by the movable block to move vertically, and the linear module drives the pressing plate to move horizontally, so as to maximize the working range and improve the working efficiency. By starting the motor, the fixed rod is screwed into the ground for fixation. When moving, the electric hydraulic push rod is started, and the electric hydraulic push rod pushes out the wheels for use. When fixing, the electric hydraulic push rod retracts the wheels to avoid the indentation caused by the vehicle-mounted leveling device on the concrete; however, when this municipal road construction leveling device is actually used, after the pressing plate finishes treating the concrete surface, the staff needs to clean the concrete attached to the bottom wall of the pressing plate, but the pressing plate cannot be detached from the linear module alone, resulting in inconvenient cleaning of the pressing plate by the staff and poor practicability.

[0030] To further understand the content of the present invention, the present invention will be described in detail with reference to the accompanying drawings and embodiments. It should be understood that the embodiments are only for explaining the present invention and not for limiting it.

[0031] The following is combined with the attached Figures 1 - 5 This embodiment will be further described in detail.

[0032] As Figure 1 As shown, a road construction vibrating and leveling device in this embodiment includes a box body 100. Rotatable rollers 101 are provided on the side walls at both ends of the box body 100. A moving frame 120 for pushing the box body 100 to move is also provided on the side walls at both ends of the box body 100. A cavity 201 with an opening downward is provided inside the box body 100. An installation plate 210 is provided inside the cavity 201. A lifting mechanism for driving the installation plate 210 to lift inside the cavity 201 is provided inside the cavity 201. The lifting mechanism includes a moving component and a driving component. The moving component is used to drive the installation plate 210 to move towards the top wall of the cavity 201, and the driving component is used to drive the installation plate 210 to move towards the opening of the cavity 201. A pressing plate 220 for vibrating and leveling the concrete is provided on the lower end surface of the installation plate 210 inside the cavity 201. Opposite fixing plates 221 are provided on the upper end surface of the pressing plate 220. A disassembly and assembly component is provided inside the installation plate 210. The disassembly and assembly component is used to disassemble and assemble the fixing plate 221 on the installation plate 210, so as to realize the disassembly and assembly of the pressing plate 220 on the installation plate 210.

[0033] In this embodiment, the fixing plate 221 is installed on the installation plate 210 through the disassembly and assembly component, so as to realize the installation of the pressing plate 220 on the installation plate 210. Then, the driving component drives the installation plate 210 to move towards the opening of the cavity 201, so that the pressing plate 220 on the installation plate 210 can extend out of the opening of the cavity 201. At this time, the staff can drive the box body 100 to move on the concrete by pulling the moving frame 120, so that the pressing plate 220 extending out of the box body 100 can level the surface of the concrete;

[0034] Among them, the fixed plate 221 is fixedly installed on the pressing plate 220. After the pressing plate 220 finishes leveling the concrete surface, the installation of the fixed plate 221 on the mounting plate 210 can be released through the disassembly and assembly component, that is, the installation of the pressing plate 220 on the mounting plate 210 can be released. Compared with the existing ones, when this kind of vibrating leveling device for municipal road construction is actually used, the pressing plate 220 can be detached from the mounting plate 210, which is convenient for the staff to clean the concrete attached to the bottom wall of the pressing plate 220, and it is more convenient to use;

[0035] Among them, when the driving component releases the driving of the mounting plate 210, the moving component will drive the mounting plate 210 to move towards the top wall of the cavity 201. The movement of the mounting plate 210 drives the pressing plate 220 to move, so that the pressing plate 220 can be located in the cavity 201, thus avoiding the pressing plate 220 from being easily knocked when the staff pushes the roller 101 on the box body 100 through the moving frame 120, thereby causing damage to the pressing plate 220;

[0036] Among them, a convex rod 102 is fixedly installed on the side wall of the box body 100, and the roller 101 is installed on the convex rod 102 through a bearing seat, realizing the rotational installation of the roller 101 on the side wall of the box body 100. The moving frame 120 is fixedly installed on the box body 100, so that the staff can make the roller 101 on the box body 100 roll on the ground by pushing the moving frame 120, thus facilitating the staff to move this vibrating leveling device;

[0037] When it is actually used, a vibration motor 1 (which is a prior art) is fixedly installed on the upper end surface of the box body 100. When the vibration motor 1 is started, the box body 100 generates vibration, that is, the pressing plate 220 installed on the mounting plate 210 can generate vibration. When the staff levels the concrete through the pressing plate 220, the pressing plate 220 can remove the air in the concrete and increase the density inside the concrete.

[0038] As Figures 1 - 2 shown, in this embodiment, positioning cylinders 110 are provided on the upper end surface of the box body 100 and near both ends, and positioning cavities 231 are provided in the positioning cylinders 110;

[0039] The moving component includes mounting rods 240 provided on the upper end surface of the mounting plate 210 and located at both ends. One end of the mounting rod 240 penetrates the box body 100 and extends into the corresponding positioning cavity 231. An installation round plate 241 is provided on the mounting rod 240 located in the positioning cavity 231. A first spring 250 is sleeved on the mounting rod 240 in the positioning cavity 231. The first spring 250 is used to push the installation round plate 241 away from the box body 100, realizing the upward movement of the mounting plate 210 in the cavity 201.

[0040] In this embodiment, through the settings of the positioning cylinder 110, the positioning cavity 231, the mounting rod 240, the mounting circular plate 241, and the first spring 250, by fixedly mounting the positioning cylinder 110 on the box body 100, the mounting rod 240 on the mounting plate 210, and the mounting circular plate 241 on the mounting rod 240, when the first spring 250 is sleeved on the mounting rod 240 located in the positioning cavity 231, the first spring 250 always pushes the mounting circular plate 241 away from the box body 100, that is, drives the mounting rod 240 to move upward, thereby realizing the movement of the mounting plate 210 towards the bottom wall of the cavity 201.

[0041] As Figures 1 - 3 shown, in this embodiment, the driving assembly includes a rotating rod 260 disposed in the cavity 201 and on the mounting plate 210. The rotating rod 260 is rotatably arranged, and a driving block 261 is provided on the rotating rod 260. The rotating rod 260 drives the driving block 261 to rotate, realizing the driving block 261 to push the mounting plate 210 towards the opening of the cavity 201. A positioning member is provided on the rotating rod 260 for positioning the position of the rotating rod 260 after rotation.

[0042] In this embodiment, through the settings of the rotating rod 260, the driving block 261, and the positioning member, by fixedly mounting one end of the driving block 261 on the rotating rod 260, when the rotating rod 260 drives the other end of the driving block 261 to rotate along the circumferential direction of the rotating rod 260, the other end of the driving block 261 will push the mounting plate 210 towards the opening of the cavity 201, so that the pressing plate 220 on the mounting plate 210 can extend out of the cavity 201 and can level the surface of the concrete;

[0043] Among them, when the rotating rod 260 drives the driving block 261 to rotate and the driving block 261 releases the push on the mounting plate 210, the first spring 250 will drive the mounting plate 210 to move towards the top wall of the cavity 201, and then the pressing plate 220 will retract into the cavity 201 for protection;

[0044] Among them, limiting blocks 211 are fixedly mounted on the opposite side walls of the mounting plate 210, and limiting grooves 212 for the corresponding limiting blocks 211 to be inserted are formed on the opposite side walls of the cavity 201 along the moving direction of the mounting plate 210. The limiting grooves 212 limit the limiting blocks 211, so that the movement of the mounting plate 210 in the cavity 201 is also limited, thereby making the movement effect of the mounting plate 210 in the cavity 201 better;

[0045] Among them, the rotating rod 260 in the cavity 201 is installed on the side wall of the cavity 201 through a bearing seat, realizing the rotational installation of the rotating rod 260 in the cavity 201;

[0046] During actual use, when the other end of the driving block 261 pushes the mounting plate 210 towards the opening of the cavity 201, the positioning member positions the angle of the rotating rod 260 after rotation, so that the driving block 261 can always maintain the pushing force on the mounting plate 210, that is, keep the mounting plate 210 moving downward to make the pressing plate 220 extend out.

[0047] As Figures 1 - 5 shown, in this embodiment, one end of the rotating rod 260 extends outside the box body 100. A rotating cavity 401 is formed on the end face of the rotating rod 260 extending outside the box body 100. Opposite clamping blocks 402 are arranged on the side wall of the rotating cavity 401 along its length direction. A plug ring 410 for closing the rotating cavity 401 is arranged at the opening of the rotating cavity 401. A baffle 262 for blocking the driving block 261 is arranged on the upper end face of the mounting plate 210. A limiting plate 300 is arranged on the side wall of the box body 100;

[0048] The positioning member includes a slidable sliding circular plate 420 arranged in the rotating cavity 401. A clamping groove for the clamping block 402 to be inserted into is arranged on the side wall of the sliding circular plate 420. A round rod 421 with one end penetrating through the plug plate and extending outside the rotating cavity 401 is arranged on the sliding circular plate 420. A handle 422 is arranged on the round rod 421 located outside the rotating cavity 401. A second spring 423 is sleeved on the round rod 421 located in the rotating cavity 401. The second spring 423 is used to push the sliding circular plate 420 away from the plug ring 410 and abut the side wall of the handle 422 against the limiting plate 300, so as to position the rotation angle of the rotating rod 260.

[0049] In this embodiment, through the settings of the rotating cavity 401, the clamping block 402, the plug ring 410, the baffle 262, the limiting plate 300, the sliding circular plate 420, the clamping groove, the round rod 421, the handle 422 and the second spring 423, the clamping block 402 is fixedly installed on the side wall of the rotating cavity 401, the plug ring 410 is threadedly installed at the opening of the rotating cavity 401, the baffle 262 is fixedly installed on the upper end face of the mounting plate 210, the limiting plate 300 is fixedly installed on the side wall of the box body 100, the round rod 421 is fixedly installed on the sliding circular plate 420, and the handle 422 is fixedly installed on the round rod 421. When the staff pulls the handle 422 outwards and drives the round rod 421 to rotate through the handle 422 to drive the rotating rod 260 to rotate, so that the side wall of the driving block 261 abuts against the baffle 262, that is, pushes the mounting plate 210 downward. At this time, the handle 422 on the rotating rod 260 is parallel to the limiting plate 300. After releasing the handle 422, the side wall of the handle 422 abuts against the side wall of the limiting plate 300 to position the rotation of the rotating rod 260;

[0050] The staff pulls the handle 422 outwards, and drives the round rod 421 to rotate through the handle 422, driving the rotating rod 260 to rotate, so that the driving block 261 rotates away from the baffle 262. Even if the mounting plate 210 moves upward under the action of the moving assembly, so that the handle 422 and the limiting plate 300 are perpendicular to each other, the driving block 261 can release the push of the mounting plate 210;

[0051] Among them, through the arrangement of the block 402 and the slot, when the handle 422 drives the round rod 421 to rotate, the round rod 421 can drive the sliding circular plate 420 to rotate, and the sliding circular plate 420 can drive the rotating rod 260 to rotate by the block 402 inserted into the slot;

[0052] When it is actually used, the second spring 423 is set so that the blocking ring 410 can limit the sliding circular plate 420 in the rotating chamber 401. At the same time, the second spring 423 on the rotating rod 260 is installed in the rotating chamber 401. The second spring 423 pushes the sliding circular plate 420 away from the blocking ring 410, so that the handle 422 on the circular rod 421 is always close to the side wall of the box body 100. When the handle 422 and the limiting plate 300 are parallel to each other, the side wall of the handle 422 can always maintain contact with the limiting plate 300, thereby preventing the sliding circular plate 420 from sliding in the rotating chamber 401, causing the handle 422 on the circular rod 421 to move with the sliding of the sliding circular plate 420, causing the handle 422 to be out of contact with the limiting plate 300, thereby affecting actual use.

[0053] like Figures 1 - 3 As shown, in this embodiment, a mounting groove 301 is provided on the bottom wall of the mounting plate 210 along its length direction;

[0054] The disassembly and assembly component includes a screw rod 310 which is arranged in the installation groove 301 and can rotate. A relative plug plate 270 is sleeved on the screw rod 310. The plug plate 270 and the screw rod 310 are threadedly matched. The rotation of the screw rod 310 is used to drive the plug plates 270 to move closer to or away from each other, and insert or slide one end of the plug plate 270 into or out of the corresponding fixed plate 221 to realize the disassembly and assembly of the fixed plate 221 on the mounting plate 210. A rotating component for driving the screw rod 310 to rotate is provided in the mounting plate 210.

[0055] In this embodiment, through the settings of the installation groove 301, the lead screw 310, the insertion plate 270 and the rotating assembly, the two ends of the lead screw 310 are installed at the two end parts of the installation groove 301 through bearing seats, realizing the rotational installation of the lead screw 310 in the installation groove 301. The side wall of the installation groove 301 limits the insertion plate 270. When the lead screw 310 is driven to rotate by the rotating assembly, when the insertion plate 270 on the lead screw 310 is inserted into the corresponding fixing plate 221, the installation of the fixing plate 221 on the installation plate 210 is realized. When the insertion plates 270 on the lead screw 310 move away from each other and slide out of the corresponding fixing plates 221, at this time, the installation of the fixing plate 221 on the insertion plate 270 is released, and the pressing plate 220 can be removed from the installation plate 210 for cleaning;

[0056] During actual use, the insertion plate 270 is L-shaped, so that one end of the insertion plate 270 can be inserted into the fixing plate 221 to install the pressing plate 220 on the installation plate 210.

[0057] As Figures 1 - 3 shown, in this embodiment, a rotating groove 321 communicating with the installation groove 301 is formed on the side wall of the installation plate 210, and a gear 311 is sleeved on the lead screw 310 at the position of the installation groove 301;

[0058] The rotating assembly includes a rack 330 that is arranged in the rotating groove 321 and can move. The rack 330 is meshed with the gear 311. The movement of the rack 330 drives the gear 311 to rotate, realizing the rotation of the lead screw 310.

[0059] In this embodiment, through the settings of the rotating groove 321, the gear 311 and the rack 330, by fixedly installing the gear 311 on the lead screw 310, when the staff pushes the rack 330 into the rotating groove 321 from the opening of the rotating groove 321, the rack 330 will drive the gear 311 to rotate, making the lead screw 310 rotate and driving the two insertion plates 270 to approach each other. When the rack 330 is taken out of the rotating groove 321, the rack 330 drives the gear 311 to rotate, making the two insertion plates 270 move away from each other;

[0060] Among them, a threaded rod 331 is installed in the rotating groove 321 and its one end penetrates through the rack 330 and can rotate. One end of the threaded rod 331 is in threaded cooperation with the bottom wall of the rotating groove 321. The threaded rod 331 is installed in the rack 330 through a bearing seat. When the rack 330 is in the rotating groove 321, by threadedly installing one end of the threaded rod 331 on the bottom wall of the rotating groove 321, the positioning of the rack 330 in the rotating groove 321 is realized, thus preventing the rack 330 from sliding out of the positioning groove. When it is necessary to take the rack 330 out of the rotating groove 321, rotate one end of the threaded rod 331 out of the bottom wall of the rotating groove 321, and the rack 330 can be taken out of the rotating groove 321;

[0061] Wherein, the side wall of the rotation groove 321 is in sliding fit with the side wall of the rack 330, so as to prevent the rotation of the threaded rod 331 from driving the rotation of the rack 330, thereby affecting the actual use;

[0062] During actual use, a notch 103 communicating with the rotation groove 321 is provided on the box body 100 corresponding to the rotation groove 321. The notch 103 is arranged along the moving direction of the mounting plate 210. The rack 330 in the rotation groove 321 can slide out of the box body 100 from the notch 103. The other end of the threaded rod 331 extends out of the notch 103. A turning handle 104 is fixedly installed at the extending end of the threaded rod 331. The staff can drive the threaded rod 331 to rotate better through the turning handle 104, making it more convenient to use.

[0063] Working principle: First, the staff pulls the handle 422 outwards and drives the round rod 421 through the handle 422 to drive the rotating rod 260 to rotate, so that the driving block 261 pushes the mounting plate 210 to move towards the opening of the cavity 201, and the pressing plate 220 extends out of the cavity 201. The staff releases the handle 422, and the side wall of the handle 422 abuts against the side wall of the limiting plate 300 to realize the positioning of the rotation of the rotating rod 260. Then, the staff pushes the box body 100 to move on the concrete through the moving frame 120, so that the pressing plate 220 can level the surface of the concrete. At this time, the vibration motor 1 is started to make the pressing plate 220 vibrate. When the pressing plate 220 levels the concrete, the pressing plate 220 can remove the air in the concrete and increase the density inside the concrete; when the leveling of the concrete is completed, the staff drives the threaded rod 331 to rotate through the turning handle 104, so that one end of the threaded rod 331 rotates out from the bottom wall of the rotation groove 321. At this time, when the rack 330 is taken out of the rotation groove 321, the rack 330 drives the gear 311 to rotate, that is, the lead screw 310 rotates, and drives the two plug plates 270 to slide out of the corresponding fixing plates 221, thereby releasing the installation of the mounting plate 210 on the fixing plates 221. At this time, the staff removes the pressing plate 220 on the mounting plate 210, which is convenient for cleaning the concrete attached to the pressing plate 220.

[0064] In summary, the above are only the preferred embodiments of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope covered by the patent of the present invention.
