Technical Field

[0001] The utility model relates to the technical field of compaction devices, in particular to a foundation compaction device used for road construction. Background Art

[0002] The foundation compaction device used in road construction usually consists of a compaction plate and a control system. The compaction plate is the part that directly contacts the ground. It vibrates at high frequency through the push of the hydraulic system to achieve the purpose of compacting the foundation. The control system is responsible for regulating the working frequency and pressure of the compaction plate to adapt to different soil types and compaction requirements. This device can effectively improve the density of the basic material and provide a solid roadbed for subsequent road construction. It is an indispensable equipment in modern road construction.

[0003] The existing foundation compaction device for road construction is usually fixed to one end of the compaction connecting rod of the compaction vehicle by bolts. Although this fixing method seems simple, there are many problems in actual operation. After working for a long time, the bolts are easily loosened due to vibration, which will cause the compaction device to be unstable, thereby affecting the compaction effect and construction safety. In view of this, we provide a foundation compaction device for road construction. Utility Model Content

[0023] Activate the No. 1 motor 201, and drive the drive shaft 204 on the top side of the tamping machine 2 to rotate through the output end of the No. 1 motor 201, and fix the eccentric metal plate 206 on the outer wall of the drive shaft 204, and connect the bottom side of the eccentric metal plate 206 with the outer wall of the top side of the movable shaft 202 through the movable rod 205, and the top of the outer wall of the movable shaft 202 penetrates and slides with the bottom end of the tamping machine 2, so that the tamping machine 2 limits the movable shaft 202 through its own bottom inner wall, so that the movable shaft 202 can only move vertically along the inner wall of the tamping machine 2. After the eccentric metal plate 206 is driven to rotate, the eccentric metal plate 206 drives the movable shaft 202 and the tamping hammer 203 to reciprocate through the movable rod 205 on the bottom side, so that the device can drive the tamping hammer 203 to tamp the road foundation through the output end of the No. 1 motor 201.

[0025] Activate the No. 1 motor 201, and drive the drive shaft 204 on the top side of the tamping machine 2 to rotate through the output end of the No. 1 motor 201, and fix the eccentric metal plate 206 on the outer wall of the drive shaft 204, connect the bottom side of the eccentric metal plate 206 with the outer wall of the top side of the movable shaft 202 through the movable rod 205, and the top of the outer wall of the movable shaft 202 penetrates and slides with the bottom end of the tamping machine 2, so that the tamping machine 2 limits the movable shaft 202 through its own bottom inner wall, so that the movable shaft 202 can only move vertically along the inner wall of the tamping machine 2. After the rotation, the eccentric metal plate 206 drives the movable shaft 202 and the tamping hammer 203 to make reciprocating motion through the movable rod 205 on the bottom side, so that the device drives the tamping hammer 203 to tamp the road foundation through the output end of the No. 1 motor 201, thereby tamping the road foundation through the tamping hammer 203 and improving the density and stability of the road foundation. During the tamping process, the operator can adjust the speed of the No. 1 motor 201 according to actual needs to achieve the best tamping effect, so that the device can adapt to the construction environment with different thickness and compaction requirements, and improve the applicability and flexibility of the equipment.

At the same time, the positioning plate 303 compresses the positioning spring 305. When the outer wall of one side of the plug plate 304 is inserted into the inner wall of the positioning frame 3 and conflicts with each other, the positioning spring 305 pushes the positioning plate 303 to move toward the top of the interior of the plug plate 304, and the positioning plate 3 03 and the plug plate 304 are engaged with each other, and the tamping frame 1 is firmly and effectively fixed in the inner center of the positioning frame 3, so that the positioning plate 303 and the plug plate 304 are engaged with each other, which effectively ensures that the tamping machine 2 is fixed on the tamping vehicle and ensures the accuracy and stability of the tamping operation. During the tamping process, due to the close connection between the positioning frame 3 and the tamping vehicle arm, and the interaction between the positioning bolt 301 and the plug plate 304, the tamping frame 1 can remain stable when subjected to impact and vibration, which helps to improve the construction quality and efficiency. In addition, the device can effectively facilitate the operator to quickly install and disassemble the tamping frame 1, and the connection structure will not loosen due to vibration after working for a long time, resulting in instability of the tamping device, thereby affecting the tamping effect and construction safety.
