Description

Rammer of convenient transportation

Technical Field

The utility model belongs to the technical field of the technique of building construction equipment and specifically relates to a ram of convenient transportation 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. The rammers are important parts of the dynamic compaction machine, and the adopted dynamic compaction energy levels are different according to different geological conditions and treatment requirements, so that the construction site is required to be provided with a plurality of rammers with different masses.

In order to solve the problems, the chinese patent with patent publication No. CN203546699U proposes a tonnage-adjustable rammer for a dynamic compaction machine, which comprises a plurality of monolithic bodies and a plurality of connecting members for connecting the monolithic bodies in a stacked manner; the connecting pieces connect and fix the single sheets in the stacking direction in a dislocation combination mode. The rammer is characterized in that a plurality of single sheets are fixedly connected in the stacking direction in a staggered combination mode of a plurality of connecting pieces, so that the weight of the rammer can be flexibly adjusted and assembled according to tonnage requirements in actual construction, the defect that a trolley needs to be provided with a plurality of rammers in the traditional construction can be overcome, and the rammer is economical and practical; in addition, the guide piece that increases can have accurate guiding orientation when making to hang, saves the time of hanging, reduces the human cost.

The above prior art solutions have the following drawbacks: the ram forms through a plurality of lamellar bodies are constituteed to when the ram is transporting, because the storage space of transport vechicle is limited, deposit the great lamellar body of more area, need carry out vertical the placing with the lamellar body, the cylindric lamellar body of vertical placing has the danger of slippage in the transportation, thereby the adjustable ram transportation difficulty of tonnage that is formed by a plurality of monolithic bodies.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a conveniently accomodate rammer of a convenient transportation of transportation.

The utility model discloses a can realize through following technical scheme:

a rammer convenient to transport comprises an upper sheet body and a lower sheet body, wherein a plurality of first screw rods perpendicular to the lower sheet body are arranged on the lower sheet body, the first screw rods penetrate between the upper sheet body and the lower sheet body, and one end, penetrating through the upper sheet body, of each first screw rod is in threaded connection with a first locking nut;
