Description
Technical Field
[0001] The utility model belongs to the technical field of municipal road and bridge construction, and more specifically, particularly relates to a pavement ramming device. Background Art
[0002] A pavement ramming device is a mechanical equipment used in civil engineering construction, mainly used for compacting materials such as soil, sand and gravel to ensure the density and flatness of subgrade and foundation. This device usually consists of one or more ramming hammers. Through the action of mechanical force, the ground materials are closely arranged to increase their bearing capacity and stability. The existing eccentric type automatic stepping ramming machine usually sets an eccentric wheel at its front end, and uses the eccentric force generated by the rotation of the eccentric wheel to drive the ramming hammer to move up and down for ramming operation. At the same time, since there are usually no wheels at the bottom of this device, it can stably drive the device bottom plate to move forward step by step under the action of inertia.
[0003] Based on the above, the existing eccentric type automatic stepping ramming machine drives the ramming hammer to move up and down for ramming operation through the eccentric wheel at the front end, and the design without wheels at the bottom enables it to move forward stably under the action of inertia. However, this design without bottom wheels makes the device inconvenient to move in the non-operation state, and it needs to be lifted or dragged manually, which increases the labor intensity. Dragging is also likely to cause equipment damage and shorten the service life. At the same time, the inconvenient movement also limits the rapid movement and transfer of the equipment on complex construction roads, which is not conducive to construction efficiency and environmental adaptability.

In use, when the wheels of the lower device are in the retracted state, the device can work more stably for ramming the ground. If you want to stop ramming and move the device, step on the release wheel pedal 11 downward with your foot. Since the release driving rack 1 and the release driven gear 2 together constitute a rack and pinion transmission mechanism, the release driven gear 2 rotates, and its function is to transmit the action of stepping on the release wheel pedal 11 downward by the foot into the rotation of the release driven gear 2.

During use, the rotation of the driven worm wheel 4 drives the rotation of the driving bevel gear 5. Since the driving bevel gear 5 and the driven bevel gear 6 together form a bevel gear transmission mechanism, the driven bevel gear 6 drives the wheel release link plate 13 to swing downward.

The first release drive gear 7 and the second release drive gear 8 together form a gear transmission mechanism. During use, the rotation of the driven bevel gear 6 drives the rotation of the first release drive gear 7. Since the first release drive gear 7 and the second release drive gear 8 together form a gear transmission mechanism, the second release drive gear 8 rotates at the same speed but in the opposite direction as the first release drive gear 7. Its function is to enable the front wheel release link plate 13 to drive the front movable wheel 14 to perform a swinging action opposite to that of the rear wheel release link plate 13, so that the front and rear wheel release link plates 13 respectively drive the two movable wheels 14 to perform unfolding actions, enabling the device to conveniently transfer positions using the movable wheels 14.

That is, when the release wheel pedal 11 moves downward, the retracted wheel pedal 12 moves upward. At this time, the wheels are in the release state. If you want to retract the wheels, you only need to step on the retracted wheel pedal 12 to drive the release wheel assembly to move in the reverse direction, and then the two wheel release connecting plates 13 drive synchronously to facilitate the retraction of the moving wheels 14 into the interior of the device loading bottom plate 18. In this way, the function of quickly releasing and retracting the wheels at the bottom of the device as needed is realized.
[0079] Specific usage method and function of the first embodiment:
[0080] In use, when the wheels of the present device are in the retracted state, the device can perform ramming work more stably. When it is desired to stop ramming and move the device, step down with the foot to release the wheel pedal 11 and it moves downward. Since the release drive rack 1 and the release driven gear 2 together form a rack and pinion transmission mechanism, the release driven gear 2 rotates. Its function is to transmit the action of stepping down on the release wheel pedal 11 with the foot into the rotation of the release driven gear 2. The rotation of the release driven gear 2 drives the rotation of the driving worm 3. Since the driving worm 3 and the driven worm gear 4 together form a worm and worm gear transmission mechanism, the driven worm gear 4 rotates. Its function is to transmit the rotation of the release driven gear 2 into the rotation of the driven worm gear 4, and at the same time make the assembly have a self-locking characteristic. The rotation of the driven worm gear 4 drives the rotation of the driving bevel gear 5. Since the driving bevel gear 5 and the driven bevel gear 6 together form a bevel gear transmission mechanism, the driven bevel gear 6 drives the wheel release link 13 to swing downward. Its function is to transmit the action of stepping down on the release wheel pedal 11 with the foot into the action of the wheel release link 13 swinging downward, so that the rear movable wheel 14 can be released and unfolded to the ground. The rotation of the driven bevel gear 6 drives the rotation of the first release drive gear 7. Since the first release drive gear 7 and the second release drive gear 8 together form a gear transmission mechanism, the second release drive gear 8 rotates at the same speed but in the opposite direction as the first release drive gear 7. Its function is to enable the front wheel release link 13 to drive the front movable wheel 14 to perform a swinging action opposite to that of the rear wheel release link 13, so that the front and rear wheel release links 13 respectively drive the two movable wheels 14 to perform an unfolding action, enabling the device to conveniently transfer its position using the movable wheels 14. The rotation of the driven bevel gear 6 drives the rotation of the first release drive gear 7. Since the first release drive gear 7 and the second release drive gear 8 together form a gear transmission mechanism, the second release drive gear 8 rotates at the same speed but in the opposite direction as the first release drive gear 7. Its function is to enable the front wheel release link 13 to drive the front movable wheel 14 to perform a swinging action opposite to that of the rear wheel release link 13, so that the front and rear wheel release links 13 respectively drive the two movable wheels 14 to perform an unfolding action, enabling the device to conveniently transfer its position using the movable wheels 14. When the release wheel pedal 11 is stepped down, since the retraction drive rack 9 and the retraction driven gear 10 together form a rack and pinion transmission mechanism and the retraction drive rack 9 and the release drive rack 1 are on different sides of the first transmission shaft 15 respectively, the retraction drive rack 9 and the release drive rack 1 move in opposite directions, that is, when the release wheel pedal 11 moves downward, the retraction wheel pedal 12 moves upward. At this time, the wheels are in the released state. If it is desired to retract the wheels, only need to step on the retraction wheel pedal 12 to drive the release wheel assembly to move in the reverse direction.Furthermore, the two wheel release connecting plates 13 are synchronously driven, facilitating the retraction of the movable wheels 14 into the device loading bottom plate 18. In this way, the function of quickly releasing and retracting the bottom wheels of the device as needed is achieved.
