Description

Technical Field

[0001] The utility model belongs to the technical field of road construction, and in particular relates to a road curbstone tamping device. Background Art

[0002] Curbstones are the strips or blocks of stone used at the edge of a road pavement to separate different functional areas, such as carriageways, sidewalks, and green belts. They are typically long strips with a rectangular or trapezoidal cross-section. During the paving process, curbstones are often hammered with a tamping device. This helps the curbstone embed better into the pavement base, increasing the friction and grip between the curbstone and the pavement. The impact force generated by the tamping compacts the soil and base material around the curbstone, thereby improving its stability and preventing it from shifting, tilting, or loosening due to external forces such as traffic and pedestrians.

[0003] Related art (Announcement No. CN213867253U) discloses a road and bridge curbstone tamping device, comprising a workbench, the upper surface of which is provided with a rectangular groove, the inner bottom wall of which is provided with a semicircular groove, the inner wall of which is rotatably connected to a circular shaft, the surface of which is fixedly connected to a support rod, the front side of which is fixedly connected to a connecting block, the front side of which is fixedly connected to a first motor, the output end of which is fixedly connected to a rotating rod, the front side of which is fixedly connected to a round rod, the outer side of which is movably in contact with a circular plate, the front side of which is fixedly connected to a T-shaped rod, the lower surface of which is fixedly connected to two square sliding rods. The present invention solves the problem of inconvenient adjustment of the tamping angle by cooperating with a second motor, a screw, a gear, and a rack.

[0004] At present, when tamping road curbs, the tamping height of the tamping head of the existing equipment is difficult to adjust. When it comes to road curbs of different heights, the fixed and unadjustable tamping head is difficult to adapt to the tamping needs of road curbs of different heights, resulting in a limited scope of application of the tamping equipment. In addition, the existing tamping equipment mostly uses a single-point tamping method to tamp road curbs. When it tamps one side of the road curb, it is easy to cause the other side of the curb to tilt up, making it difficult to quickly and effectively achieve synchronous stability on both sides of the curb. Utility Model Content

[0005] In response to the existing problems in the prior art, such as the difficulty in adjusting the tamping height of the tamping head of existing equipment, and the difficulty in adapting the fixed and unadjustable tamping head to the tamping requirements of road curbs of different heights, which results in a limited scope of application of the tamping equipment, the present invention provides a road curb tamping device that can adjust the range of reciprocating tamping of the base plate and the tamping head, thereby enabling the tamping head to tamp road curbs of different heights as needed, that is, it can adapt to the tamping requirements of road curbs of different heights, avoid the problem of limited scope of application of the tamping equipment, improve the versatility of the equipment, and expand the scope of application of the equipment. The specific technical solution is as follows:

[0006] A road curb tamping device includes an equipment main body, a vertical plate connected to the front side of the equipment main body through a connecting component, the vertical plate passes through and is rotatably connected to a first rotating shaft in a horizontal direction, two first gears are symmetrically installed on the first rotating shaft, one end of a connecting column is fixedly installed on the bottom end of the vertical plate, and a base body is fixedly installed on the other end of the connecting column, the base body passes through and is rotatably connected to a second rotating shaft in a horizontal direction, two second gears are symmetrically installed on the second rotating shaft, and the two second gears are respectively meshed with the two first gears, two cams are symmetrically and detachably installed on the second rotating shaft, an elastic component is provided under the base body, the bottom end of the elastic component is connected to a base plate, and a tamping head is fixedly installed on the bottom end of the base plate.

[0007] In the above technical solution, a collar is fixedly mounted on the side wall of the cam, and a limit pin is provided through a thread of the collar and the side wall of the second rotating shaft.

[0008] In the above technical solution, the elastic component includes a telescopic rod fixedly installed between the base and the bottom plate, a spring is sleeved on the outside of the telescopic rod, and both ends of the spring are fixedly connected to the bottom end of the base and the top end of the bottom plate respectively.

[0009] In the above technical solution, the first rotating shaft is rotated by a driving assembly;

[0010] The driving assembly includes a connecting rod fixedly mounted on the side wall of the vertical plate, a pedestal mounted on the end of the connecting rod, the pedestal being arranged horizontally, a motor mounted on the pedestal, and an output end of the motor being connected to the first rotating shaft.

[0011] In the above technical solution, the seat body and the vertical plate are arranged parallel to each other.

[0012] In the above technical solution, the device body includes a mounting frame, a base is fixedly mounted on the bottom end of the mounting frame, and universal wheels are respectively mounted at the four corners of the bottom end of the base.

[0013] In the above technical solution, a handle is installed on the rear side wall of the mounting frame.

[0014] In the above technical solution, the connecting assembly includes two connecting arms fixedly mounted on the front side wall of the mounting frame, and a reinforcing plate is installed between the two connecting arms;

[0015] Wherein, the front end of the connecting arm is fixedly connected to the side wall of the vertical plate.

[0016] Compared with the prior art, the road curb tamping device of the present invention has the following beneficial effects:

[0017] First, the tamping height of the tamping head of the existing equipment is difficult to adjust. When it comes to road curbs of different heights, the fixed and unadjustable tamping head is difficult to adapt to the tamping requirements of road curbs of different heights, resulting in a problem that the scope of application of the tamping equipment is limited. The utility model can adjust the reciprocating tamping range of the bottom plate and the tamping head by disassembling and replacing cams of different diameters, thereby enabling the tamping head to tamp road curbs of different heights as needed, that is, it can adapt to the tamping requirements of road curbs of different heights, avoid the problem of limited application range of the tamping equipment, improve the versatility of the equipment, and expand the application range of the equipment;

[0018] Second, in view of the problem that the existing tamping equipment mostly adopts a single-point tamping method to tamp the road curb, when it tamps one side of the road curb, it is easy to cause the other side of the curb to tilt up, making it difficult to quickly and effectively achieve synchronous stability of both sides of the curb, the utility model can promote the synchronous circumferential rotation of the two cams on both sides, so as to ensure that the bottom plate and the tamping head can move back and forth in the vertical direction. Compared with the single-point tamping method, the utility model can ensure that the tamping head can strike the road curb in a straight up and down manner to apply a vertical tamping force to the road curb, avoiding the problem of the road curb tilting caused by unilateral single-point knocking, and more easily achieving rapid stability of both sides of the road curb;

[0019] Third, the present invention provides cams at both ends of the second rotating shaft, enabling the two cams to be removed outward. The force driving the second rotating shaft to rotate comes from the rotation of the first gear and the first rotating shaft above, thus avoiding the problem of providing a driving force on the side of the second rotating shaft that makes the cams difficult to remove.

[0020] Fourth, the utility model can drive the two cams to rotate synchronously through the motor, the first rotating shaft, the first gear, the second gear and the second rotating shaft. The two cams can be rotated simultaneously by the same power, so as to cause the bottom plate and the two sides of the tamping head to move synchronously under force, ensuring that the moving direction of the tamping head remains vertical and will not deflect;

[0021] 5. The utility model can realize the lifting and reciprocating movement of the bottom plate and the tamping head relative to the base body through the connection of the mounting frame, the connecting arm, the reinforcing plate and the vertical plate, thereby realizing the tamping head to repeatedly strike the road curb stone. The repeated reciprocating striking can gradually embed the road curb stone into the road base layer, which is more conducive to ensuring the stability of the road curb stone.

[0022] In summary, the utility model can adjust the range of the reciprocating knocking of the base plate and the ramming head, thereby enabling the ramming head to knock on road curbs of different heights as needed, that is, it can adapt to the ramming needs of road curbs of different heights, avoid the problem of limited application range of the ramming equipment, improve the versatility of the equipment, and expand the application range of the equipment. In addition, it can ensure that the ramming head knocks straight up and down for surface contact to apply a vertical ramming force to the road curb, avoid the problem of the road curb warping caused by unilateral single-point knocking, and more easily achieve rapid stabilization of both sides of the road curb.

DETAILED DESCRIPTION

[0028] The following is a combination of specific implementation cases and attached Figures 1 to 4 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0029] See Figures 1 to 4As shown, a road curb tamping device includes a device body, the front side of the device body is connected to a vertical plate 4 through a connecting assembly, the vertical plate 4 passes through the horizontal direction and is rotatably connected to a first rotating shaft 5 through a bearing, two first gears 6 are symmetrically installed on the first rotating shaft 5, one end of a connecting column 10 is fixedly installed on the bottom end of the vertical plate 4, and the other end of the connecting column 10 is fixedly installed on a base body 11, the base body 11 passes through the horizontal direction and is rotatably connected to a second rotating shaft 15 through a bearing, two second gears 16 are symmetrically installed on the second rotating shaft 15, and the two second gears 16 are respectively meshed with the two first gears 6 The two first gears 6 are connected together. When the two first gears 6 rotate, they can drive the two second gears 16 to rotate synchronously. Two cams 18 are detachably installed on the left and right sides of the second rotating shaft 15. The rotating second gear 16 can drive the two cams 18 on the second rotating shaft 15 to rotate synchronously. An elastic component is provided under the base body 11. The bottom end of the elastic component is connected to the bottom plate 14. The bottom end of the bottom plate 14 is fixedly mounted with a ramming head 20. The base body 11 is arranged parallel to the vertical plate 4, thereby ensuring that the first rotating shaft 5 and the second rotating shaft 15 also remain parallel, so that the first gear 6 and the second gear 16 are stably engaged.

[0030] When the two second gears 16 rotate synchronously, the second gear 16 drives the second rotating shaft 15 and the two cams 18 to rotate synchronously. When the distal side of the cam 18 gradually rotates to fit the upper surface of the base plate 14, the elastic component is deformed, thereby causing the base plate 14 and the ramming head 20 to move downward, so that the ramming head 20 moves downward to tamp the road curb; as the cam 18 continues to rotate, the proximal side of the cam 18 gradually rotates to fit the upper surface of the base plate 14. In this process, the elastic component is used to cause the base plate 14 and the ramming head 20 to move upward, so that the ramming head 20 is lifted off the surface of the road curb; with the continuous rotation of the cam 18 and the cooperation of the elastic component, the base plate 14 and the ramming head 20 can be reciprocated in the vertical direction, that is, the road curb below the ramming head 20 is subjected to intermittent and continuous tamping.

[0031] In addition, the main reference Figure 2As shown, a collar 17 is fixedly installed on the side wall of the cam 18, and a limit pin 19 is provided through a thread on the collar 17 and the side wall of the second rotating shaft 15; when tamping road curbs of different heights, the limit pin 19 is removed from the collar 17 with the help of a tool. At this time, the cam 18 loses its limit on the second rotating shaft 15, and the cam 18 is removed outward from the second rotating shaft 15, and a new suitable cam 18 is replaced, and the limit pin 19 is re-threaded into the inner cavity of the collar 17 at the new cam 18, and the limit pin 19 is threaded through the second rotating shaft 15, so that the collar 17 and the cam 18 are reinstalled at the second rotating shaft 15, and the range of the reciprocating knocking of the base plate 14 and the tamping head 20 can be adjusted, thereby realizing that the tamping head 20 can knock road curbs of different heights as needed, that is, it can adapt to the tamping needs of road curbs of different heights.

[0032] For details, see Figure 1 and Figure 3 As shown, the elastic component includes a telescopic rod 12 fixedly installed between the base body 11 and the base plate 14, and a spring 13 is provided on the outside of the telescopic rod 12, and the two ends of the spring 13 are fixedly connected to the bottom end of the base body 11 and the top end of the base plate 14 respectively. When the distal side of the cam 18 gradually rotates to fit the upper surface of the base plate 14, the bottom end of the telescopic rod 12 is prompted to move downward, and at the same time, the spring 13 is forced to stretch, thereby prompting the base plate 14 and the ramming head 20 to move downward, so that the ramming head 20 moves downward to tamp the road curb; as the cam 18 continues to rotate, the proximal side of the cam 18 gradually rotates to fit the upper surface of the base plate 14. In this process, the elastic force of the spring 13 is used to prompt the total length of the telescopic rod 12 to shrink, and prompt the base plate 14 and the ramming head 20 to move upward, so that the ramming head 20 is lifted off the surface of the road curb.

[0033] Other main references Figure 1 As shown, the first rotating shaft 5 is rotated by a driving assembly; the driving assembly includes a connecting rod 7 fixedly mounted on the side wall of the vertical plate 4, a pedestal 8 is mounted on the end of the connecting rod 7, the pedestal 8 is horizontally arranged, a motor 9 is mounted on the pedestal 8, the output end of the motor 9 is connected to the first rotating shaft 5, and the turned-on motor 9 drives the first rotating shaft 5 and the two first gears 6 to rotate synchronously, so as to promote the synchronous rotation of the two second gears 16, and the second gear 16 drives the second rotating shaft 15 and the two cams 18 to rotate synchronously.

[0034] Main references Figure 3 and Figure 4 As shown, the main body of the device includes a mounting frame 1, a base 21 is fixedly installed at the bottom end of the mounting frame 1, and universal wheels 22 are respectively installed at the four corners of the bottom end of the base 21. Through the setting of the universal wheels 22, the entire device can be moved to the desired position. The device has high flexibility and is easy to transfer; a handle 23 is installed on the rear side wall of the mounting frame 1, and it is easier to push the device to move by holding the handle 23.

[0035] Main references Figure 1 and Figure 4 As shown, the connecting assembly includes two connecting arms 2 fixedly mounted on the front side walls of the mounting frame 1, and a reinforcing plate 3 is installed between the two connecting arms 2; wherein, the front end of the connecting arm 2 is fixedly connected to the side wall of the vertical plate 4, and a stable connection between the mounting frame 1 and the vertical plate 4 can be achieved through the connecting arm 2 and the reinforcing plate 3, and will not interfere with the lifting and ramming movement of the base plate 14 below the vertical plate 4 and the ramming head 20.

[0036] It is worth noting that in the present application, the motor 9 adopts a self-locking motor commonly used on the market whose output end can be locked. When the motor stops working, the output end can self-lock and will not rotate under external force. The motor 9 is a forward and reverse motor commonly used on the market. Its output end can rotate forward or reverse according to the use requirements. It can meet the above-mentioned use requirements; the telescopic rod 12 is composed of two rod bodies that are nested and slidably connected to each other. The total length of the telescopic rod 12 can be changed under the action of external force, but the telescopic rod 12 always keeps moving in the vertical direction; the above-mentioned existing components are not described in detail here.

[0037] The working principle of a road curb tamping device in this embodiment is as follows:

[0038] When tamping road curbs of different heights, the limiting pin 19 is removed from the collar 17 with the help of a tool. At this time, the cam 18 loses its limit on the second shaft 15. The cam 18 is removed outward from the second shaft 15 and replaced with a new suitable cam 18. The limiting pin 19 is threadedly embedded in the inner cavity of the collar 17 at the new cam 18, and the limiting pin 19 is threaded through the second shaft 15 to achieve the reinstallation of the collar 17 and the cam 18 on the second shaft 15. The range of the reciprocating tapping of the base plate 14 and the tamping head 20 can be adjusted, thereby enabling the tamping head 20 to tap road curbs of different heights as needed, that is, it can adapt to the tamping requirements of road curbs of different heights.

[0039] The worker holds the handle 23 and pushes the device until the device moves to the construction position, causing the base plate 14 and the tamping head 20 to be located above the road curb to be tamped;

[0040] The turned-on motor 9 drives the first rotating shaft 5 and the two first gears 6 to rotate synchronously, so as to promote the synchronous rotation of the two second gears 16, and the second gear 16 drives the second rotating shaft 15 and the two cams 18 to rotate synchronously. When the distal side of the cam 18 gradually rotates to fit the upper surface of the bottom plate 14, the bottom end of the telescopic rod 12 is forced to move downward, and at the same time the spring 13 is forced to stretch, thereby promoting the bottom plate 14 and the ramming head 20 to move downward, so that the ramming head 20 moves downward to tamp the road curb; as the cam 18 continues to rotate, the proximal side of the cam 18 gradually rotates to fit the upper surface of the bottom plate 14. In this process, with the help of The elastic force of the spring 13 causes the total length of the telescopic rod 12 to contract, and causes the bottom plate 14 and the tamping head 20 to move upward, so that the tamping head 20 is lifted off the surface of the road curb. With the continuous rotation of the cam 18 and the cooperation of the telescopic rod 12 and the spring 13, the bottom plate 14 and the tamping head 20 can be reciprocated in the vertical direction, that is, the road curb below the tamping head 20 is subjected to intermittent and continuous tamping action. The tamping head 20 strikes the road curb in a straight up and down manner, so as to apply a vertical tamping force to the road curb, thereby avoiding the problem of the road curb being lifted due to unilateral single-point tapping, and more easily achieving rapid stabilization of both sides of the road curb.

[0041] The utility model can adjust the range of the reciprocating knocking of the base plate 14 and the ramming head 20, thereby enabling the ramming head 20 to knock on road curbs of different heights as needed, that is, it can adapt to the ramming needs of road curbs of different heights, avoid the problem of limited application range of the ramming equipment, improve the versatility of the equipment, and expand the application range of the equipment. In addition, it can ensure that the ramming head 20 knocks straight up and down for surface contact, so as to apply a vertical ramming force to the road curb, avoid the problem of the road curb warping caused by unilateral single-point knocking, and more easily achieve rapid stabilization of both sides of the road curb.

[0042] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
