[0001] The present application relates to the field of municipal engineering, and in particular to a municipal road pavement repair ramming machine. Background Art

[0002] Municipal roads often become damaged during daily use due to heavy vehicle traffic, and these damaged roads often require repair. Repairing the damaged area requires cleaning and preparing the surface, filling the damaged area with repair material, compacting and leveling the surface, and finally performing necessary maintenance and inspections.

[0003] At present, ramming machines are generally large in size, so they are often difficult to apply to ramming work of small-area damaged road subgrades. Moreover, when using large ramming machines to repair road surfaces, it is usually necessary to close the road for construction, which will affect the passage of vehicles. Therefore, there are obvious shortcomings. Utility Model Content

[0004] In order to improve the problem that large ramming machines are difficult to apply to ramming work of roadbeds with small areas of damaged roads, the present application provides a municipal road pavement repair ramming machine.

[0005] The municipal road pavement repair ramming machine provided in this application adopts the following technical solution:

[0006] A municipal road pavement repair ramming machine includes a mobile body, a load-bearing frame arranged on the mobile body, a reversing wheel arranged on the load-bearing frame, a pull rope wrapped around the reversing wheel, one end of the pull rope is tied to a rammed earth block, and a wire harness assembly arranged on the mobile body for pulling and releasing the other end of the pull rope relative to the rammed earth block.

[0007] By adopting the above technical solution, the harness assembly pulls and releases the pull rope, thereby lifting the rammed earth blocks to a high position and dropping them down, thereby compacting the roadbed on the damaged road surface. Due to the lightweight structure and small size of the technical solution of this application, it is suitable for repairing small areas of damaged road surface and has little impact on vehicle traffic.

[0008] Optionally, the wiring harness assembly includes a C-shaped arc ring fixedly mounted on the mobile vehicle body, a turntable tightly attached to the inner wall of the arc ring is rotatably arranged inside the arc ring, an outer ring groove with a C-shaped cross-section is circumferentially opened on the inner wall of the arc ring, and an inner ring groove is circumferentially opened on the outer wall of the turntable, the cross-sections of the inner ring groove and the outer ring groove are matched to form a full circle, and the other end of the pull rope relative to the rammed earth block is provided with balls sliding in the outer ring groove and the inner ring groove, and a push head extending into the outer ring groove and used to push the balls is also provided on the outer wall of the turntable, a fixed frame and a motor electrically connected to the control system are arranged on the mobile vehicle body, the turntable is rotatably mounted on the fixed frame, and the output shaft of the motor is transmitted to the turntable through a synchronous wheel and a synchronous belt.

[0009] By adopting the above technical solution, workers start the motor through the control system, and the output shaft of the motor is transmitted to the turntable through the synchronous belt and synchronous wheel. The turntable drives the push head to rotate, pushing it from the outside of the arc ring into the inner ring groove, and pushing the ball to move circumferentially in the inner ring groove. The ball drives the rammed earth block upward through the pull rope. When the push head pushes the ball out of the inner ring groove and moves out of the inner ring groove itself, the ball is pulled back to the inner ring groove through the pull rope under the action of the gravity of the rammed earth block, and the rammed earth block falls to achieve tamping, thereby realizing the pulling and releasing of the pull rope.

[0010] Optionally, the interior of the ball is hollow and includes two hemispherical shells, the end of the pull rope is inserted into the ball and knotted, and the two shells are fixedly connected.

[0011] By adopting the above technical solution, the end of the pull rope is constrained in the spherical shell in a knotted manner, and the connection between the two is strong and stable.

[0012] Optionally, an oil box with a hollow interior is arranged on the arc ring. The oil box is filled with lubricating oil and an oil delivery hole is opened between the oil box and the outer ring groove.

[0013] By adopting the above technical solution, the lubricating oil in the oil box flows into the outer ring groove through the oil delivery hole, so that the balls can move more smoothly in the outer ring groove and the inner ring groove.

[0014] Optionally, a cross bar is provided inside the oil box, and a hole plug for sealing the oil supply hole is vertically slidably penetrated through the cross bar, and a support plate is arranged on the outer wall of the hole plug, and the support plate is located below the cross bar. The hole plug is supported by a compression spring relative to the position between the support plate and the cross bar.

[0015] By adopting the above technical solution, when the friction resistance of the ball moving in the inner ring groove is large, the worker manually pulls up the plug, and the lubricating oil can flow into the inner ring groove. After the worker loosens the plug, the plug re-closes the oil supply hole, thereby reducing the waste caused by excessive lubricating oil in the inner and outer ring grooves.

[0016] Optionally, the rammed earth block includes a rammed earth body, a threaded tube threadedly connected to the top of the rammed earth body, the top end of the threaded tube is connected to a pull rope, and a lifting rod is arranged on the rammed earth body.

[0017] By adopting the above technical solution, when the ramming is completed, the worker unscrews the threaded pipe from the rammed earth body, and then lifts the rammed earth body onto the mobile vehicle.

[0018] Optionally, a plurality of rotating arms are hinged on the mobile body, and an end of each rotating arm away from the mobile body is provided with an adjustable support foot that is supported on the ground.

[0019] By adopting the above technical solution, when the damaged area of ​​the road surface is large and irregular, workers can rotate the rotating arm according to the actual situation, so that multiple adjustable legs can cooperate to support the mobile vehicle body on the road surface.

[0020] Optionally, magnetic blocks for mutual magnetic attraction are arranged on the movable body and the rotating arm.

[0021] By adopting the above technical solution, when the rammer is not in use and is in motion, the moving body and the magnetic blocks on the rotating arm attract each other, thereby reducing the possibility of the rotating arm rotating indiscriminately and accidentally injuring pedestrians.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The harness assembly pulls and releases the pull rope, so that the rammed earth blocks can be lifted to a high place and then dropped, thereby compacting the roadbed on the damaged road surface. Due to the lightweight and compact structure of the technical solution of this application, it is suitable for repairing small areas of damaged road surface with minimal impact on vehicle traffic.

[0024] 2. The worker starts the motor through the control system. The output shaft of the motor is transmitted to the turntable through the synchronous belt and synchronous wheel. The turntable drives the push head to rotate, pushing it from the outside of the arc ring into the inner ring groove, and pushing the ball to move circumferentially in the inner ring groove. The ball drives the rammed earth block upward through the pull rope. When the push head pushes the ball out of the inner ring groove and moves out of the inner ring groove itself, the ball is pulled back to the inner ring groove through the pull rope under the action of the gravity of the rammed earth block. The rammed earth block falls to realize the tamping, thereby realizing the pulling and releasing of the pull rope. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following is combined with Figure 1-4 This application is described in further detail.

[0031] The embodiment of the present application discloses a municipal road pavement repair rammer.

[0032] Reference Figure 1 The municipal road pavement repair ramming machine includes a mobile vehicle. The mobile vehicle body 1 can be a small or medium-sized driving vehicle in the existing technology. A bearing frame 2 is slidingly arranged on the mobile vehicle body 1 and is positioned by tightening bolts. The bearing frame 2 is made of aluminum alloy in the existing technology.

[0033] Reference Figure 1 A reversing wheel 3 is bolted to the top of the carrier 2, and a pull rope 4 is wrapped around the reversing wheel 3. One end of the pull rope 4 is tied to a rammed earth block 5. A wire harness assembly is arranged on the mobile body 1 for pulling and releasing the other end of the pull rope 4 relative to the rammed earth block 5.

[0034] Reference Figure 1 and Figure 2 The wiring harness assembly includes an arc ring 6 and a fixed frame 10 bolted to the mobile body 1. The arc ring 6 is C-shaped. A turntable 7 coaxial with the arc ring 6 is rotatably arranged on the fixed frame 10, and the outer circumferential wall of the turntable 7 is tightly attached to the inner arc surface of the arc ring 6.

[0035] Reference Figure 1 and Figure 2 An outer ring groove 601 with a C-shaped cross section is opened circumferentially on the inner arc surface of the arc ring 6, and the outer ring groove 601 extends to both ends of the arc ring 6. An inner ring groove 701 is opened circumferentially on the outer wall of the turntable 7, and the cross-sections of the inner ring groove 701 and the outer ring groove 601 are matched to form a full circle.

[0036] Reference Figure 1 and Figure 2 The other end of the pull rope 4 relative to the rammed earth block 5 is provided with a ball 8 that slides in the outer ring groove 601 and the inner ring groove 701. The ball 8 is hollow inside and is welded by two hemispherical shells. The corresponding end of the pull rope 4 is inserted into the ball 8 and tied.

[0037] Reference Figure 1 and Figure 2 A push head 9 is integrally formed on the outer wall of the turntable 7 and extends into the outer ring groove 601 and slides with it. The push head 9 is used to push the ball 8 to move circumferentially along the inner ring groove 701.

[0038] Reference Figure 1 and Figure 2 The mobile body 1 is also bolted with a motor 11 electrically connected to the control system. The output shaft of the motor 11 is transmitted to the turntable 7 through a synchronous wheel 12 and a synchronous belt 13. A battery for powering the motor 11 can be placed on the mobile body 1.

[0039] Reference Figure 1 and Figure 2 The worker starts the motor 11 through the control system. The output shaft of the motor 11 transmits the power to the turntable 7 through the synchronous belt 13 and the synchronous wheel 12. The turntable 7 drives the push head 9 to rotate, pushing it from the outside of the arc ring 6 into the inner ring groove 701, and pushing the ball 8 to move circumferentially in the inner ring groove 701. The ball 8 drives the rammed earth block 5 to lift upward through the pull rope 4.

[0040] When the push head 9 pushes the ball 8 out of the inner groove 701 and the push head 9 also moves out of the inner groove 701, the ball 8 is pulled back to the inner groove 701 by the pull rope 4 under the action of the gravity of the rammed earth block 5 and moves in the reverse direction, and the rammed earth block 5 falls to realize ramming.

[0041] Reference Figure 2 and Figure 3 An internally hollow oil box 14 is bolted to the arc ring 6. The oil box 14 is filled with lubricating oil and has an oil delivery hole 141 between it and the outer ring groove 601. A horizontal crossbar 15 is horizontally mounted inside the oil box 14. A plug 16 for sealing the oil delivery hole 141 is vertically slidably inserted through the crossbar 15. A circular support plate 17 is integrally formed on the outer wall of the plug 16. The support plate 17 is located below the crossbar 15. A compression spring 18 supports the plug 16 between the support plate 17 and the crossbar 15.

[0042] Reference Figure 2 and Figure 3 When the ball 8 has difficulty moving in the inner ring groove 701 and the outer ring groove 601, the worker manually pulls up the plug 16. At this time, the lubricating oil can flow into the inner ring groove 701 through the oil delivery hole 141, thereby improving the smoothness of the movement of the ball 8 in the inner ring groove 701.

[0043] After the worker loosens the plug 16 , the compression spring 18 pushes the plug 16 downward to reclose the oil delivery hole 141 , thereby reducing the waste caused by excessive lubricating oil in the inner ring groove 701 and the outer ring groove 601 .

[0044] Reference Figure 1 and Figure 4The rammed earth block 5 includes a rammed earth body 51, a threaded tube 52 threadedly connected to the top of the rammed earth body 51, the corresponding end of the pull rope 4 is inserted into the closed top of the threaded tube 52 and is tied with an anti-slip block 54, and a lifting rod 53 is integrally formed on the rammed earth body 51.

[0045] Reference Figure 1 and Figure 4 When the tamping is completed, the worker unscrews the threaded tube 52 from the tamping body 51 and then lifts the tamping body 51 onto the mobile vehicle 1.

[0046] Reference Figure 1 A plurality of rotating arms 19 are hinged on the mobile body 1, and an adjustable support foot 20 is arranged on the ground at the end of each rotating arm 19 away from the mobile body 1, and magnetic blocks (not shown in the figure) are arranged on the mobile body 1 and the rotating arms 19 for magnetic attraction to each other.

[0047] When the rammer is not in use and is in motion, the mobile body 1 and the magnetic blocks on the rotating arm 19 attract each other, thereby reducing the possibility of the rotating arm 19 rotating indiscriminately and accidentally injuring pedestrians.

[0048] The working principle of a municipal road pavement repair ramming machine according to an embodiment of the present application is as follows: a worker starts the motor 11 through a control system, and the output shaft of the motor 11 transmits the power to the turntable 7 via a synchronous belt 13 and a synchronous wheel 12. The turntable 7 drives the push head 9 to rotate, pushing the ball 8 from the outside of the arc ring 6 into the inner ring groove 701, and pushing the ball 8 to move circumferentially within the inner ring groove 701. The ball 8 drives the rammed earth block 5 upward via the pull rope 4. After the push head 9 pushes the ball 8 out of the inner ring groove 701 and moves out of the inner ring groove 701, the ball 8 is pulled back into the inner ring groove 701 by the pull rope 4 under the action of the gravity of the rammed earth block 5 and moves in the opposite direction, causing the rammed earth block 5 to fall and complete the ramming.

[0049] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application.
