Abstract

The utility model discloses a hole enlarging machine. The utility model is characterized in that a rotating rod joint is arranged in a protective cylinder, the lower end of the rotating rod joint is connected with a hexagonal rotating rod, a hexagonal rod nut which is matched with the hexagonal rotating rod is arranged on the hexagonal rotating rod, and the hexagonal rod nut is connected with an upper hole enlarging scraping plate through a hinge. The lower end of the hexagonal rod nut is provided with a bottom support, a lower hole enlarging scraping plate is fixed on the bottom support by a hinge, the upper and the lower scraping plates are connected together by a hinge, and a baffle plate for returning earth is fixed on the lower scraping plate. The lower end of the lower hole enlarging scraping plate is fixed with a collector for internally falling earth, and the outside of the collector for internally falling earth is connected with a collector for externally falling earth. The utility model has the advantages of rapid hole enlargement and thorough earth return.

Description

Staving press

The utility model belongs to excavation machinery, relates to a kind of staving press.

At present, a kind of new technology of using castinplace pile to beat the building foundation has appearred in building trade.But castinplace pile will get out a hole that diameter is less with auger earlier on the ground, then in reaming, so the development of counter-boring techniques directly affects the development of irritating the stake technology.Prior art is the method with the machine support hole, support hole of a band hydraulic system.This method needs a cover hydraulic system, has increased construction cost., in addition, the soil that overhangs behind the support hole is all fallen in the hole, it can't be removed thoroughly, and this will certainly influence the quality of irritating stake.

The purpose of this utility model provides the rapid reaming of a kind of energy, the complete liquidation in the hole of surplus soil can be come out, effectively guaranteed the staving press of reaming quality after reaming.

The utility model is by casing, and bull stick joint, six side's bull sticks, six square bar mothers and collet are formed body, by hinge upper and lower reaming scraper plate is installed at six square bars on the female and collet, in six side's bull stick lower ends have recover with outside recover; For guaranteeing back soil, on lower scraping plate, also be fixed with and return native baffle plate.

The utility model has the advantages that simple in structurely, reaming is rapid, returns soil thoroughly, comparable hydraulic pressure support hole machine energy conservation.

Describe in detail below in conjunction with accompanying drawing.

The utility model has one to be used for the bull stick joint 1 that is connected with engine, and a casing 2 is arranged outside the bull stick joint.There is a shoulder hole said bull stick joint inside, is processed with internal thread in the lower end in this hole, and one six side's bull stick 4 is by being threaded on the bull stick joint, and fixing by nut 3.On six side's bull sticks 4, be set with one six square bar mother 14, on six sides of six square bar mothers 14, all be connected with reaming scraper plate 13 on by hinge.Be connected with UR scraper plate 12 in last reaming scraper plate 13 lower ends by hinge 6.For reaming is rapid, all be welded with the screw die of making by Hardmetal materials 5 at the edge of upper and lower scraper plate.Also be connected with collet 11 in UR scraper plate 12 lower ends by hinge.On lower scraping plate, also be welded with and return native plate 7.The native recover 10 that falls in the female lower end of six square bars also is connected with the native recover 10 that falls in, is said does not have base plate.Be set with the native recover 9 that falls outside in the interior native recover outside that falls, the native recover 9 that falls outward has base plate, in its side skidway hole is arranged, in the native recover that falls can fall outside by slideway 10A and move in the skidway hole of native recover.

During use, the bull stick joint is connected with dynamic power machine, dynamic power machine drives the bull stick joint and six side's bull sticks rotate, six side's bull sticks drive the female and upper and lower scraper plate of six square bars again and rotate, scraper plate backup plate tooth is wiped the soil around the hole off, and the soil that is reamed falls and fallen in advancing in the native recover 10 by the native strip of returning on the lower scraping plate.The diameter of reaming can be realized by the angle of regulating between upper and lower scraper plate.After soil is fallen certain volume, upwards mention this machine, in fall native recover along moving on the skidway hole of the native recover that falls outward, after reaching the limit of the position, inside and outside the native recover that falls rise together, above the soil zone in the hole is arrived.

Claims

1, a kind of staving press comprises casing, it is characterized in that: a bull stick joint is arranged in casing, be connected with one six side's bull stick in bull stick joint lower end, six square bar mothers that match with it are arranged on six side's bull sticks, six square bar mothers link together by hinge and last reaming scraper plate; In the bull stick lower end collet is arranged, on collet, be fixed with the UR scraper plate, link together by hinge between upper and lower scraper plate, on lower scraping plate, be fixed with and return native baffle plate by hinge; Be fixed with the native recover that falls in six side's bull stick lower ends, be connected with the native recover that falls outside in the interior native recover outside that falls.

2,, it is characterized in that a skidway hole is arranged on the native recover that falls outside according to the said staving press of claim 1, on the interior native recover that falls, a slideway corresponding with it is arranged also.
