Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, in particular to a tamping and compacting device for road bridge and subgrade construction. Background Art

[0002] As a major category of construction projects such as highways, railways, and urban rail transit, roadbed engineering is indispensable in engineering construction from the aspects of reducing the overall cost of the project, functional requirements, and soil and stone mixing requirements. A tamping machine is a machine used for compaction. It is a compaction machine that uses impact and impact vibration to compact backfill soil in layers. It is mostly used to level and compact the foundation during construction. After searching, the patent with application number 202220017419.8 discloses a tamping and compaction device for road and bridge subgrade construction, including a machine base, a machine body, an electric telescopic rod, a buffer support mechanism, a tamping machine housing, a hydraulic cylinder, and a compaction plate; a machine body is installed above the machine base; an electric telescopic rod is installed at the bottom of the machine body, and a moving wheel is installed at the telescopic end of the bottom of the electric telescopic rod; a buffer support mechanism is installed at the bottom of the machine base, and a tamping machine housing is supported and arranged through the buffer support mechanism, and a hydraulic cylinder is installed above the tamping machine housing through an installation frame.

[0003] However, during actual use, the applicant found that when compacting the roadbed, the hydraulic cylinder was driven to drive the piston rod to extend and retract up and down, thereby driving the compaction plate to move up and down to compact the roadbed. This driving method causes the compaction plate to move up and down at a uniform speed, resulting in poor compaction effect of the compaction plate on the roadbed. In view of this, we propose a tamping and compaction device for road and bridge roadbed construction. Utility Model Content

[0021] See also Figure 1-4 As shown, the utility model provides a technical solution:

[0022] Embodiment 1: A tamping and compacting device for road and bridge subgrade construction comprises a vehicle seat 1, a battery pack 6 is fixedly connected to the top of the vehicle seat 1, a power switch 5 is fixedly installed on the top of the battery pack 6, the power switch 5 is electrically connected to the battery pack 6 through a wire, a motor mounting bracket 11 is fixedly connected to the top of the vehicle seat 1 in front of the battery pack 6, a reduction motor 4 is fixedly installed on the rear side wall of the motor mounting bracket 11, the reduction motor 4 is electrically connected to the power switch 5 through a wire, a support frame 12 is fixedly connected to the top of the vehicle seat 1 in front of the motor mounting bracket 11, and the support frame 12 is arranged at two locations in front and behind, the upper parts of the two support frames 12 are rotatably connected to a rotating shaft 13 through bearings, the rear end of the rotating shaft 13 is fixedly connected to the rotating end of the reduction motor 4, and the two support frames 12 are connected between A driving wheel 9 is sleeved and fixed on the rotating shaft 13, and crescent-shaped protrusions 91 are centrally symmetrically arranged on the peripheral side walls of the driving wheel 9. A lifting arm 2 is movably penetrated through the top of the seat 1 on the front side of the support frame 12, and a connecting column 21 is fixedly arranged on the rear side wall of the upper end of the lifting arm 2. The connecting column 21 is rotatably connected to the roller 10 through a bearing. The setting of the roller 10 is used to convert the sliding friction between the connecting column 21 and the crescent-shaped protrusion 91 into rolling friction, thereby reducing the wear of the connecting column 21 and the crescent-shaped protrusion 91, thereby extending the service life. By driving the two crescent-shaped protrusions 91 to rotate by the driving wheel 9, the lifting arm 2 can be lifted upward together with the rammer head 3, and after the rammer head 3 is lifted to the highest position, the rammer head 3 can be free to fall. The body moves, effectively impacts the ground, and the tamping effect is better. The lower end of the lifting arm 2 is fixedly connected with a tamping hammer head 3, and an avoidance groove 14 is provided at the bottom of the seat 1 above the tamping hammer head 3, which is used to achieve the avoidance of the tamping hammer head 3, so that the tamping hammer head 3 can be smoothly moved up and down. The top of the seat 1 on the rear side of the battery pack 6 is fixedly connected with a pusher 7, and the bottom of the seat 1 is rotatably connected with a walking wheel 8 through the wheel axle. Through the cooperation of the pusher 7 and the walking wheel 8, it is convenient for personnel to move the roadbed tamping and compacting device. When compacting the road and bridge roadbed construction, personnel can manually push the pusher 7 to move the compacting device to the required operation position, and then drive the reduction motor 4 to rotate through the power switch 5. At this time, the reduction motor 4 can rotate The driving shaft 13 is driven to rotate together with the driving wheel 9. The rotation of the driving wheel 9 can drive the crescent-shaped protrusion 91 to rotate. The rotation of the crescent-shaped protrusion 91 can lift the roller 10 together with the connecting column 21 upward. In this process, the roller 10 can roll along the side wall of the crescent-shaped protrusion 91. The upward movement of the connecting column 21 can drive the lifting arm 2 to lift up together with the tamping hammer head 3. When the tamping hammer head 3 is lifted to the highest position, as the crescent-shaped protrusion 91 continues to rotate, the roller 10 is separated from the crescent-shaped protrusion 91. At this time, the tamping hammer head 3 can realize free fall downward and hit the ground under the action of gravity, and can be lifted up again as the driving wheel 9 continues to rotate. Such reciprocating movement up and down can realize effective tamping and compaction of the roadbed.During the tamping and compacting of the roadbed, personnel can push the device to move along the roadbed.

[0023] Embodiment 2: The difference between this embodiment and embodiment 1 lies in that, the bottom of the rammer head 3 is fixedly connected to the rammer base plate 16 by connecting bolts 15, and bolt grooves 31 are symmetrically provided on both sides of the rammer head 3, and two bolt grooves 31 are provided side by side on each side, and the end of the connecting bolt 15 is located in the bolt groove 31, and the lower end of the connecting bolt 15 passes through the rammer head 3 and is screwed into the threaded hole provided at the top of the rammer base plate 16, so that personnel can conveniently replace the rammer base plate 16 with deformation at the bottom, thereby ensuring the compaction effect of the roadbed and avoiding the need to replace the entire rammer head 3. When the bottom of the rammer base plate 16 is deformed after being used for a period of time and affects the compaction effect of the roadbed, the four connecting bolts 15 can be unscrewed from the rammer base plate 16, and the rammer base plate 16 can be removed from the bottom of the rammer head 3 for replacement, thereby ensuring the compaction effect of the roadbed and eliminating the need to replace the entire rammer head 3.

[0024] Working principle: When in use, when compacting the road and bridge subgrade construction, the personnel can manually push the pusher 7 to move the compacting device to the required operation position, and then drive the reduction motor 4 to rotate through the power switch 5. At this time, the rotation of the reduction motor 4 can drive the rotating shaft 13 to rotate together with the driving wheel 9, and the rotation of the driving wheel 9 can drive the crescent-shaped protrusion 91 to rotate. The rotation of the crescent-shaped protrusion 91 can lift the roller 10 together with the connecting column 21 upward. In this process, the roller 10 can roll along the side wall of the crescent-shaped protrusion 91, and the upward movement of the connecting column 21 can drive the lifting arm 2 to lift up together with the tamping hammer head 3. When the tamping hammer head 3 is lifted to the highest position, as the crescent-shaped protrusion 91 continues to move, the lifting arm 2 can be lifted upward together with the tamping hammer head 3. As the wheel 10 continues to rotate, the roller 10 disengages from the crescent-shaped protrusion 91. At this time, the rammer head 3 can, under the action of gravity, realize free fall downward and hit the ground, and can be lifted up again as the driving wheel 9 continues to rotate. This up and down reciprocating movement can achieve effective tamping and compaction of the roadbed. During the tamping and compaction of the roadbed, personnel can push the device to move along the roadbed. After a period of use, if the bottom of the rammer base plate 16 is deformed and affects the compaction effect of the roadbed, the four connecting bolts 15 can be unscrewed from the rammer base plate 16, and the rammer base plate 16 can be removed from the bottom of the rammer head 3 for replacement, thereby ensuring the compaction effect of the roadbed without replacing the entire rammer head 3.
