[0002] In highway construction, in order to ensure the stability, durability and bearing capacity of the road structure, a subgrade compaction device is generally used to compact the subgrade. The subgrade compaction device is a rammer, which is a compaction machine that uses impact and impact vibration to compact the backfill soil layer by layer.
[0003] The existing subgrade compaction devices are generally installed on vehicles for work. When in use, by starting the engine of the rammer, the rammer starts to impact the soil up and down or reciprocally, so that the water and air in the soil are squeezed out, and then the soil particles are closely arranged to form a more solid subgrade foundation. And in order to prevent the flying gravel from hurting the surrounding workers, a protective cover will be installed on the outer periphery of the rammer to prevent the gravel from splashing.
[0004] However, when the protective cover is used for a long time, it will be bent and deformed due to the impact of gravel, which will lead to a decrease in the local bearing capacity, and then it needs to be replaced. Since the protective cover is generally of an integral design and is installed on the machine body by bolts, specific tools are required during the replacement process. In the case of lack of tools, the replacement rate of the protective cover is low, and the replacement cost is large, which makes the use economy low. Content of the Utility Model

Specific embodiments
[0025] In order to clearly and completely describe the purpose, technical solution of the present utility model, and make the advantages more clearly understood, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.
[0026] Embodiment 1: Please refer to Figures 1 to 9 , the present utility model provides a technical solution: a subgrade compaction device for highway construction, including a body 1, which is composed of a frame, an engine, a control system, etc. A rammer 2 is slidably connected to the inner bottom end of the body 1. When using the rammer 2, by starting the engine to operate, the rammer 2 can be driven to compact the subgrade. An installation ring 3 is sleeved outside the rammer 2, and the top end of the installation ring 3 is in contact with the bottom end of the body 1, so that the installation ring 3 can be stably installed. Two connecting blocks 4 are fixedly connected to the top end of the installation ring 3, and the connecting blocks 4 are slidably connected inside the body 1. The body 1 plays a limiting role on the connecting blocks 4. Two card slots 5 are opened inside the body 1, and a card block 6 is clamped inside the card slots 5. The card block 6 penetrates through the connecting block 4 and is slidably connected inside the body 1, so that the installation ring 3 can be conveniently installed. A plurality of installation blocks 7 are slidably connected inside the installation ring 3, and a protective member 8 is fixedly connected to the bottom end of the installation block 7. The protective member 8 is used to block flying gravel, thereby preventing the gravel from hurting the surrounding workers.
[0027] When it is necessary to replace the protective part 8, by moving the two clamping blocks 6 towards the separated side, the clamping blocks 6 can be disengaged from the inside of the clamping groove 5 and the connecting block 4, so that the connecting block 4 is no longer restricted. Then, pull the connecting block 4 downward, so that the connecting block 4 can be disengaged from the inside of the machine body 1, so that the mounting ring 3 can be conveniently disassembled. Then, pull the protective part 8 downward, so that the protective part 8 can drive the mounting block 7 to disengage from the inside of the mounting ring 3, so as to conveniently disassemble and replace a single damaged protective part 8. On the contrary, the protective part 8 can be conveniently installed on the mounting ring 3, and the mounting ring 3 can be conveniently installed inside the machine body 1. Then, there is no need to use specific tools to disassemble bolts. This not only makes the replacement efficiency of the protective part 8 relatively high, but also enables targeted replacement of parts of the protective cover, so that the economic efficiency of use is relatively high.
[0028] Embodiment 2: On the basis of Embodiment 1, in order to realize convenient replacement of the mounting ring 3, two placement grooves 19 are opened inside the machine body 1. A rotating rod 9 is rotatably connected to the right side inside of the machine body 1. The machine body 1 plays a limiting role on the rotating rod 9, so that the rotating rod 9 can rotate smoothly. Two pull ropes 10 are fixedly connected to the outside of the rotating rod 9. The other ends of the pull ropes 10 are fixedly connected to a placement piece 12. The placement piece 12 is slidably connected inside the placement groove 19. The placement groove 19 plays a limiting role on the placement piece 12, so that the placement piece 12 will not deviate when sliding. The end of the placement piece 12 far away from the pull rope 10 is fixedly connected to the clamping block 6. The clamping block 6 is slidably connected inside the placement groove 19. The placement groove 19 plays a limiting role on the clamping block 6, so that the clamping block 6 can slide smoothly. An elastic member 11 is sleeved on the outside of the pull rope 10. One end of the elastic member 11 is fixedly connected to the inner wall of the placement groove 19, and the other end of the elastic member 11 is fixedly connected to the placement piece 12. A sealing member 18 is sleeved on the right side of the rotating rod 9. The left side of the sealing member 18 is inserted into the right end inside of the machine body 1. The sealing member 18 is used to protect the rotating rod 9, so that the rotating rod 9 will not deviate when not in use.
[0029] When it is necessary to replace the mounting ring 3, by pulling out the sealing member 18 from the inside of the machine body 1, and then rotating the rotating rod 9, so that the rotating rod 9 can wind the pull rope 10, so that the pull rope 10 can pull the placement piece 12 to move inward, so that the placement piece 12 can squeeze the elastic member 11 to deform, and the placement piece 12 can pull the clamping block 6 to disengage from the inside of the clamping groove 5 and the connecting block 4, so that the mounting ring 3 is no longer restricted. On the contrary, by inserting the connecting block 4 into the inside of the machine body 1, and then loosening the rotating rod 9, the elastic member 11 can perform a reset movement, so that the elastic member 11 can push the placement piece 12 to move inward, so that the placement piece 12 can penetrate through the inside of the connecting block 4 and the clamping groove 5 to be engaged, so that the mounting ring 3 can be conveniently installed.
[0030] Embodiment 3: On the basis of Embodiment 2, in order to facilitate the replacement of a single protective part 8 and ensure a relatively stable installation, a plurality of limiting grooves 13 are formed inside the mounting ring 3, and a sliding groove 15 is formed inside the mounting block 7. An elastic member II 16 is fixedly connected to the inner wall of the sliding groove 15, and the other end of the elastic member II 16 is fixedly connected to a slider 17. The slider 17 is slidably connected inside the sliding groove 15, and the sliding groove 15 limits the slider 17, so that the slider 17 can slide smoothly. A curved block 14 is fixedly connected to the side of the slider 17 away from the elastic member II 16. The bottom end of the curved block 14 slides inside the limiting groove 13, and the limiting groove 13 limits the curved block 14. With the cooperation of the limiting groove 13 and the curved block 14, the protective part 8 can be stably installed.
[0031] When the mounting ring 3 is removed, by moving the two curved blocks 14 towards each other, the curved block 14 can push the slider 17 to squeeze the elastic member II 16 to deform, so that the slider 17 can enter the inside of the sliding groove 15, and then the slider 17 no longer restricts the mounting block 7. At this time, the protective part 8 is pulled downwards, so that the mounting block 7 can be separated from the inside of the mounting ring 3, and then the protective part 8 can be conveniently disassembled. On the contrary, by directly sliding the mounting block 7 upwards, the outer arc surface of the curved block 14 can slide inside the mounting ring 3, so that the curved block 14 can squeeze the elastic member II 16 to deform through the slider 17. When the curved block 14 and the limiting groove 13 are at the same horizontal level, the elastic member II 16 can perform a reset movement, so that the elastic member II 16 can push the slider 17 to move outwards, and then the slider 17 can push the curved block 14 to engage with the inside of the limiting groove 13, so that the protective part 8 is installed relatively stably.
[0032] During actual use, by pulling out the seal 18 from the inside of the body 1, and then rotating the rotating rod 9, the rotating rod 9 can wind the pulling rope 10, so that the pulling rope 10 can pull the placing sheet 12 to move inward, causing the placing sheet 12 to squeeze the first elastic member 11 to deform, and the placing sheet 12 pulls the clamping block 6 to disengage from the inside of the clamping groove 5 and the connecting block 4, so that the mounting ring 3 is no longer restricted, and then pulling the mounting ring 3 downward, so that the connecting block 4 can disengage from the inside of the body 1, so that the upper side of the limiting groove 13 is exposed to the outside. Then, by moving the two arc-shaped blocks 14 toward each other, the arc-shaped blocks 14 can push the slider 17 to squeeze the second elastic member 16 to deform, so that the slider 17 can enter the inside of the sliding groove 15, so that the slider 17 no longer restricts the mounting block 7. At this time, pulling the protective member 8 downward, so that the mounting block 7 can disengage from the inside of the mounting ring 3, so that the protective member 8 can be conveniently disassembled. On the contrary, by directly sliding the mounting block 7 upward, the arc surface outside the arc-shaped block 14 can slide inside the mounting ring 3, so that the arc-shaped block 14 can squeeze the second elastic member 16 to deform through the slider 17. When the arc-shaped block 14 and the limiting groove 13 are at the same horizontal level, the second elastic member 16 can perform a reset movement, so that the second elastic member 16 can push the slider 17 to move outward, so that the slider 17 can push the arc-shaped block 14 to engage with the inside of the limiting groove 13, so that the protective member 8 is installed more stably. Then, by inserting the connecting block 4 into the inside of the body 1 and releasing the rotating rod 9, the first elastic member 11 can perform a reset movement, so that the first elastic member 11 can push the placing sheet 12 to move inward, so that the placing sheet 12 can penetrate through the connecting block 4 and engage with the inside of the clamping groove 5, so that the mounting ring 3 can be conveniently installed.
