Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of small tamping equipment, in particular to a tamping machine modified from a hydraulic breaker. Background Art
[0002] The separation of urban rainwater and sewage is an important part of the Yangtze River protection work. The process involves the construction of a large number of working wells and inspection wells. The quality of the roadbed backfill compaction around the working wells and inspection wells determines the service life of the road. At present, the compaction work mainly uses traditional rammers and high-speed hydraulic rammers. Traditional rammers are hand-held by construction workers, with a low compaction rate, and work around the wells, which poses a safety hazard to construction workers. The compaction surface of the high-speed hydraulic rammer is usually circular and tangent to the outer wall of the working well. There are local positions that are not compacted in place, and the number of tamping times is relatively large. In addition, the high-speed hydraulic rammer is a large-scale compaction equipment, and the working space of the working well and inspection well is limited, and the work flexibility is limited. Utility Model Content
[0003] In view of the deficiencies in the prior art, the utility model provides a tamping machine modified from a hydraulic breaker. In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:
[0004] The rammer modified from a hydraulic breaker comprises a hydraulic device and a breaker body. The hydraulic device drives the breaker body to perform reciprocating motion. The rammer also comprises a connecting rod, a connector and a rammer plate. One end of the connecting rod is fixedly connected to the breaker body, and the other end is fixedly connected to the connector. The connector is detachably connected to the rammer plate. The rammer plate is square and horizontally arranged, and an arc-shaped recessed portion is arranged on one side of the rammer plate.
[0005] Furthermore, the recessed portion matches the outer edge of the working well or inspection well to be rammed.
[0006] Furthermore, two ends of the recessed portion are configured to be chamfered in an arc shape.
[0007] Furthermore, corresponding connecting holes are evenly formed on the tamping plate and the connector, and bolts are arranged in the connecting holes.
[0008] Furthermore, the connector is configured to be cylindrical, and the top surface of the connector is arched upward.
[0009] Furthermore, a gasket is provided between the connector and the tamping plate.
[0010] Compared with the prior art, the utility model has the following beneficial effects:
[0011] The hydraulic device drives the breaker body to vibrate, and the breaker body drives the tamping plate to vibrate to carry out dense backfilling. By setting a recessed portion on the tamping plate, the dense backfill area around the working well or inspection well is increased during multiple dense backfillings. The number of vibrations of the tamping plate is reduced, the tamping efficiency is improved, and the number of positions where tamping is not in place is reduced. In addition, by modifying a small crusher to form a tamping machine, the work is more flexible, the cost is lower, and the use is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0019] Embodiment 1:
[0020] like Figures 1 to 4 As shown, the utility model provides a technical solution, a ramming machine modified by a hydraulic breaker hammer, including a hydraulic device 3 and a breaker hammer body 32. The hydraulic device 3 drives the breaker hammer body 32 to reciprocate. The hydraulic device 3 is provided with a mounting hole 31 connected to the mechanical arm of the small crusher. Figure 1 As shown, it also includes a connecting rod 21, a connector 2 and a tamping plate 1. One end of the connecting rod 21 is fixedly connected to the breaker body 32, and the other end is fixedly connected to the connector 2. The connector 2 is detachably connected to the tamping plate 1. The tamping plate 1 is square and horizontally arranged, and an arc-shaped recessed portion 13 is arranged on one side of the tamping plate 1.
[0021] When the rammer is working, the hydraulic device 3 drives the breaker body 32 to vibrate, and the breaker body 32 drives the rammer plate 1 to vibrate to perform dense backfilling. By setting a recessed portion 13 on the rammer plate 1, the dense backfilling area around the working well or inspection well by the rammer plate 1 during multiple dense backfilling is increased, the number of vibrations of the rammer plate 1 is reduced, the ramming efficiency is improved, and the number of positions that are not rammed in place is reduced. In addition, by modifying a small crusher to form a rammer, the work is more flexible, the cost is lower, and the use is more convenient.
[0022] In this embodiment, the small crusher can perform ground crushing by vibration, which is an existing mature equipment and mature technology. It will not be described in detail here. This solution uses the vibration working mode of the small crusher and improves the tamping structure to achieve dense tamping. In this embodiment, the connecting rod 21 and the breaker body 32, and the connecting rod 21 and the connector 2 are fixed by welding.
[0023] In this embodiment, both ends of the recessed portion 13 are configured as arc-shaped chamfers 12 to prevent the tamping plate 1 from scratching the working well or inspection well during the tamping and compacting work, thereby facilitating use and improving safety.
[0024] Embodiment 2:
[0025] Based on Example 1, the recessed portion 13 matches the outer edge of the working well or inspection well to be rammed. By matching the arc of the recessed portion 13 with the outer wall of the working well and inspection well of common size, it is convenient to reduce the number of ramming times, improve work efficiency, and facilitate ramming construction.
[0026] Embodiment 3:
[0027] On the basis of Example 1, corresponding connection holes 11 are evenly opened on the tamping plate 1 and the connector 2, and bolts 23 are arranged in the connection holes 11. In addition, the tamping plate 1 and the connector 2 can also be disassembled and fixed by threaded connection, so as to facilitate the replacement of the tamping plate 1 with the recessed parts 13 of different sizes to adapt to different working wells or inspection wells, and facilitate the tamping construction.
[0028] In addition, the connector 2 is configured to be cylindrical, and the top surface of the connector 2 is arched upward, so that the connector 2 can support the tamping plate 1 during vibration to prevent the two sides of the tamping plate 1 from warping.
[0029] In order to reduce the reverse impact force of the tamping plate 1, a gasket 22 is provided between the connector 2 and the tamping plate 1. The gasket 22 is a polymer conductive gasket 22, which prolongs the service life of the tamping machine.
[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
