Detailed Description

As shown in fig. 1-4: a device for tamping in holes comprises a bottom plate 1, a steel cover plate 2, a concave channel steel 3, a lifter 4, a vertical rod 5, a bearing pulley 6, a high-strength bolt 7, a wire locking device 8, a lifting hook 9, a lifting ring 10, a steel wire rope 11 and a tamping hammer 12;

Further, the bottom plate constitute by four planks, the both ends of plank are equipped with respectively and are no less than 2 bolt holes, fix with the bolt through with two plank tip and apron, form isosceles trapezoid's bottom plate, one of them minor face plank is together fixed with the lifting machine, passes through the apron with gravity through the pole setting and transmits the plank both sides, reduces the junction of lifting machine and plank and the interval of tip to reduce the deformation of this plank, guarantee the stability of lifting machine during operation. The length of the wood boards arranged in parallel with the short edges is determined by the aperture size, and the wood boards arranged on the waist lines at the two sides play a structural role, so that the integral stability is maintained. The bottom plate mainly dissipates the gravity of the rammer and ensures the stability of the whole body, so that a wooden plate with light weight and high strength can be adopted.

Further, the apron adopt the higher iron plate of rigidity to a concave type channel-section steel of welded fastening on the apron, fix concave type channel-section steel on the steel apron through the welding, the orientation of notch is the central point of bottom plate, sets up the bolt hole on the concave type channel-section steel contralateral steel sheet simultaneously, concave type channel-section steel both sides are equipped with the bolt hole for fixed pole setting prevents that the pole setting tip from producing the displacement of horizontal direction in the use, concave type channel-section steel becomes a support of pole setting tip.

Furthermore, the vertical rod is a steel pipe, a bolt hole is formed in the lower end of the vertical pipe, and the lower end of the vertical pipe and the concave channel steel are fixed through bolts. The upper ends of the vertical rods are provided with high-strength bolt holes, the upper ends of the vertical rods at the two ends of the short plate are arranged on the inner side, bearing pulleys are arranged between the two vertical rods on the inner side, the upper ends of the vertical rods at the two ends of the long plate are arranged on the outer side, and the upper ends of the four vertical rods and the bearing pulleys are fixed together by high-strength bolts through the bolt holes at the;

further, the bearing pulley constitute by bearing 62, pulley 63 and dustcoat 61, the bearing passes through high strength bolt fastening in the middle of the pole setting, dustcoat both sides baffle is fixed on the bearing, the baffle in the dustcoat outside is adjustable fender, can dismantle outside baffle through arranging the slide in both sides edge, outer baffle can be used to install the lifting rope and prevent that wire rope from droing on the pulley in the use. The pulley is combined with the bearing, so that rolling can replace friction, and the abrasion of the equipment is reduced.

Further, wire rope one end and lifting hook link to each other through the locking wire knot, the lifting hook can link to each other with the ram, the ram is cylindric, set up to the round platform form can not only have certain compaction to the bottom soil body at the in-process of ramming, also can with to the side soil body of ram. The rammer can be made of concrete through a mold on site, and a steel bar hanging ring is embedded in the upper surface of the rammer, so that the lifting hook at one end of the steel wire rope is connected with the hanging ring prefabricated on the rammer. Make elevating system and ram be connected for lift ram provides kinetic energy for the ram.

The pole setting is bearing structure, and the bearing pulley has reduced the loss of device, and the dustcoat has also avoided wire rope to transfer the condition of the easy indiscriminate rope of output of in-process, and the base through the cover connection has increased holistic stability, and each member adopts bolted connection, has embodied and has transported the convenience, installs faster advantage. The operating principle is that the hoisting machine is used for hoisting the rammer, the rope is quickly released to the hoisting machine after the rammer is lifted to a certain height, the rammer is made to fall to be hammered, and the height and the hammering times are determined through field experiments when the rammer falls.

The steel wire rope on the hoister winds on the pulley in the structure, and is combined with the movable baffle on the outer cover of the bearing pulley and then is vertical to the ground. One end of the steel wire rope is fixed with a hook through a wire locking device. The steel wire rope is landed to find the vertical point of the lifting hook, then the known vertical point is marked on two waist line boards and a long edge board of the bottom board, the position of the vertical point can be determined when the bottom board is laid, the position of the vertical point where the lifting hook of the device is vertically arranged is consistent with the position of the hole center, and the arrangement is completed at one time.

The method comprises the steps of firstly manufacturing a circular truncated cone-shaped concrete rammer according to the aperture, wherein the ratio of the diameter of the upper bottom of the rammer to the diameter of the lower bottom of the rammer is 3:2, the ratio of the diameter of the upper bottom of the rammer to the height of the upper bottom of the rammer to the diameter of the aperture of the lower bottom of the rammer is 2:1, the ratio of the diameter of the upper bottom of the rammer to the aperture of the upper bottom of the rammer to the aperture of the upper bottom of the rammer is 3:4, after the rammer is completed, placing the rammer under a lifting hook of a device, lifting the rammer, placing a protective cylinder under the lifted rammer, filling materials with the thickness of 500mm into the protective cylinder.

During the use process, firstly, a protective cover is manufactured above the hole site, the rammer is arranged above the protective cover, the center of gravity of the rammer is arranged at the center point of the hole, then the bottom plate is arranged, and the prepared vertical point mark on the bottom plate is arranged at the hole center position. And then, the device is subjected to the installation operation, the lifting hook is manually lifted up the lifting ring prefabricated on the rammer, the protective cover is withdrawn, the material is manually placed in the hole, the lifting height of the rammer is controlled according to experimental parameters, and the tamping times are repeated for a plurality of times until the material is tamped to the required height.

The device has the advantages of light weight, convenient and flexible installation, high overall stability and the like, and can be used for construction by configuring the rammer according to the aperture size, thereby reducing the construction cost, reducing the construction danger and shortening the construction period; is suitable for tamping in holes with the hole diameter within 1.2 meters.
