Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figures 1-4 In this embodiment of the utility model, a road compaction device for urban roads and traffic engineering includes a housing 1. A connecting seat 26 is fixedly installed on the outer wall of the housing 1. A hydraulic cylinder 2 and an accumulator 3 are fixedly installed inside the housing 1.

A connecting plate 9 is fixedly connected to the lower end of the force seat 6. A compaction plate 10 is provided at the bottom of the connecting plate 9. Two symmetrically arranged insertion grooves 13 are opened on the top of the connecting plate 9. Multiple bolts 14 are inserted through each insertion groove 13. The compaction plate 10... The top of the connecting plate 9 is provided with threaded holes 15 corresponding to the bolts 14. The bolts 14 and the threaded holes 15 are adapted to each other. A positioning plate 16 is provided in the mounting groove 13. A handle 18 is fixedly installed on the top of the positioning plate 16.

A plurality of chains 25 are fixedly connected to the top of the connecting plate 9. The top ends of the chains 25 are fixedly connected to the outer wall of the housing 1.
[0019] By adopting the above-mentioned scheme, this utility model, during use, after starting the hydraulic cylinder 2 to lift the rammer 4, drives the rammer 4 to fall quickly and strike the force seat 6, thus applying an impact force to the connecting plate 9 and the rammer plate 10 of the force seat 6, thereby compacting the bottom surface using the rammer plate 10. The cooperation between the bolt 14 and the threaded hole 15 facilitates the disassembly and assembly of the rammer plate 10 on the mounting plate 9, making it convenient to replace the rammer plate 10 of different sizes according to usage requirements. The setting of the positioning plate 16 and the positioning groove 17 allows the bolt 14 to be locked in the embedding groove 13, preventing the impact force on the rammer plate 10 during the compaction process from causing the bolts 14 to loosen, thereby improving the reliability of the rammer plate 10 installation. The setting of the locking mechanism allows the positioning plate 16 to be locked in the embedding groove 13.

One end of the plug rod 20 is inserted into the mounting groove 13 and is located directly above the positioning plate 16. The other end of the plug rod 20 is fixedly connected to a pull rod 24.
[0021] Furthermore, a baffle 21 is fixedly sleeved on the outer wall of the insertion rod 20 located inside the stepped hole 19, and a blocking plate 23 is movably sleeved on the outer wall of the insertion rod 20 located outside the connecting plate 9. The blocking plate 23 is fixedly connected to the outer wall of the connecting plate 9, and a spring 22 is sleeved on the outer wall of the insertion rod 20 located between the baffle 21 and the blocking plate 23.
[0022] By setting the insertion rod 20, the positioning plate 16 can be locked in the mounting groove 13 to prevent the positioning plate 16 from coming out of the mounting groove 13 during the compaction of the road surface. By setting the spring 22, a pushing force can be applied to the insertion rod 20, thereby preventing the insertion rod 20 from coming out of the mounting groove 13 when no one is operating it, thus improving the reliability of locking the positioning plate 16.
