Description
Technical Field
The utility model belongs to the technical field of the technique of building construction equipment and specifically relates to a ram that gas pocket is difficult for blockking up is related to.
Background
The dynamic compactor is a device which utilizes high impact energy generated by high fall of a rammer to strongly extrude materials with better performance, such as broken stones, rubbles, slag and the like into a foundation to form one aggregate pier in the foundation, and a composite foundation is formed between the piers so as to improve the bearing capacity of the foundation and reduce settlement. The detacher is a rammer unhooking device used on a dynamic compaction machine. The rammer is a heavy block used for improving the bearing capacity of the deep foundation and resisting falling.
In the process of reinforcing the foundation by dynamic compaction, after the dynamic compactor lifts the rammer to a high position, the rammer is unhooked and falls freely, the ground is tamped repeatedly for many times, the kinetic energy of the rammer forms strong shock waves and high stress in the soil, the foundation is impacted and vibrated, and the soil body is tamped strongly, so that the strength of the foundation is improved, the compressibility is reduced, the vibration liquefaction resistance of the foundation is improved, and the collapsibility is eliminated.
Chinese patent with patent publication No. CN202247841U proposes a flat-bottom multipurpose type strong ramming hammer, which comprises an integral axisymmetric closed shell body, wherein the inner cavity of the closed shell body is filled with concrete filled with pig iron blocks and cement, a plurality of vent holes are uniformly distributed and communicated with the upper end face and the lower end face of the hammer body, and a hook is arranged in the middle of the upper end face of the hammer body; the hammer body is a combined assembly body, and the main hammer body is arranged at the upper part of the auxiliary hammer body through a fastening piece; the vent hole penetrating through the upper end face and the lower end face of the whole rammer is a circular truncated cone-shaped hole, and the hole diameter is large at the upper part and small at the lower part; the distance between two hanging points of the hook is larger than 600 mm, and the middle point of the hook body of the hook is bent in a 90-degree arc transition mode. Because the hammer body is a combined assembly body of the main hammer and the auxiliary hammer, only one main hammer and the series of auxiliary hammers are needed, the hammer can be flexibly used for balancing weight, and the carrying workload is less during construction; the vent hole is a circular truncated cone-shaped hole, the diameter of the vent hole is large at the top and small at the bottom, and the channel of the vent hole tends to be gradually wide and is not easy to block; because the distance between the hanging points of the hook is larger, the middle point of the hook body of the hook is bent in a transition way by a 90-degree arc, and the aligning and releasing effects of the hook are better.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1 and 3, for the utility model discloses a ram that gas pocket is difficult for blockking up, including the ram body 1 of cylinder form, the top of ram body 1 is fixed with rings 7, and a plurality of vertical exhaust holes 2 have been seted up to the bottom of ram body 1, and a plurality of exhaust holes 2 distribute with the axis circumference of ram body 1. A plurality of ventholes 3 have been seted up along its radially in 1 week side of ram body, be fixed with on the pore wall of venthole 3 and be used for reducing the dust and get into dust screen 14 in the venthole 3, a plurality of ventholes 3 and a plurality of exhaust hole 2 one-to-one intercommunication, sliding hole 4 has been seted up to the roof of exhaust hole 2, sliding hole 4 runs through to the top of ram body 1, and this internal soil cleaning component that is used for clearing up the interior earth of exhaust hole 2 that is equipped with of ram. After rammer body 1 strikes ground, because the soil horizon all pressurized around the exhaust hole 2 of rammer body 1 bottom and sinks to in the protruding entering exhaust hole 2 of soil horizon in the exhaust hole 2, along with rammer body 1 lifts up the back, clear up the earth in exhaust hole 2 through the subassembly of clearing earth, thereby rammer body 1's exhaust hole 2 is difficult for blockking up.
Referring to fig. 1 and 4, the soil cleaning assembly comprises a guide rod 5 and a shielding plate 6, wherein the shielding plate 6 is used for shielding the exhaust hole 2, and the shielding plate 6 is slidably arranged in the exhaust hole 2; guide bar 5 slides and wears to establish in sliding tray 10, and guide bar 5 one end is fixed with shielding plate 6, and the top of rammer body 1 is worn out to the other end, the limiting plate 15 in the aperture that the top fixedly connected with area of guide bar 5 is greater than sliding hole 4. The week side of shielding plate 6 is fixed with two sliding blocks 9, and two sliding blocks 9 use the axis symmetric distribution of shielding plate 6 on shielding plate 6, and have seted up two sliding tray 10 along its length direction on the lateral wall of exhaust hole 2, and sliding tray 10 runs through to the bottom of rammer body 1, and two sliding blocks 9 slide respectively and set up in two sliding tray 10. After the rammer body 1 impacts the ground, the shielding plate 6 reduces the amount of soil entering the exhaust hole 2, the guide rod 5 slides upwards to drive the shielding plate 6 to slide upwards, so that the air outlet hole 3 is communicated with the exhaust hole 2 below the shielding plate 6, the air in the exhaust hole 2 is conveniently discharged, and the rammer body 1 is conveniently lifted; the gliding guide bar 5 drives the baffle plate 6 to glide down, so that the baffle plate 6 pushes out and scrapes off the soil in the exhaust hole 2, and the exhaust hole 2 is not easy to block.
Referring to fig. 1 and 3, the guide rod 5 is sleeved with a first spring 8, two ends of the first spring 8 are respectively fixed on the upper side of the shielding plate 6 and the top wall of the exhaust hole 2, when the shielding plate 6 is located at the bottom end of the rammer body 1, the first spring 8 is in a normal state, so that when the shielding plate 6 is extruded by a soil layer to ascend, the first spring 8 blocks the shielding plate 6 to ascend, and soil is reduced to enter the exhaust hole 2. When the shielding plate 6 is slid upwards, the first spring 8 is compressed, so that after the rammer body 1 is lifted, the shielding plate 6 is driven to slide downwards by the elastic force of the first spring 8, soil in the exhaust hole 2 is pushed out, and the exhaust hole 2 is not easily blocked by soil.
