Description

Rotary auxiliary slag removal barrel drill

Technical Field

The utility model belongs to the technical field of pile foundation engineering construction, concretely relates to rock drill cylinder bores, especially relates to a supplementary scarfing cinder cylinder of rotation type bores.

Background

With the rapid growth of economic construction and the continuous increase of reform and openness in China, higher requirements and challenges are put forward on design and construction. The rotary drilling rig is a construction machine suitable for hole forming operation in building foundation engineering. A rock barrel drill used by the rotary drilling rig is a special drill bit and has the main advantage of fast footage. However, a plurality of problems also exist in the construction process, one of the troublesome problems is that after the drilling is completed, broken stones, clay and the like in the barrel drill can be adhered together to block the barrel drill, so that rock and soil residues in the barrel drill are difficult to quickly clean, the construction efficiency is reduced, and the engineering progress is slowed. In order to solve the problems, a large amount of data search, field investigation and related experiments are conducted to research, and a novel rotary drum drill for assisting in cleaning slag is invented.

Disclosure of Invention

The utility model aims at providing an supplementary scarfing cinder section of thick bamboo of rotation type bores, not only clears up the ground that blocks up in the section of thick bamboo bores easily, has also accelerated to save manpower and materials, has guaranteed the speed and the quality of construction, and convenient operation, simple structure, technique are feasible.

The utility model adopts the technical proposal that: the rotary auxiliary slag removal barrel drill consists of a flange, a base, a barrel drill body, a cutting tooth, a gear, a rocker and a partition plate; the flange is positioned at the upper end of the cylindrical drill body; the base is fixed at four top corners of the flange; the section of the cylindrical drill body is circular; the cutting picks are uniformly distributed at the bottom end of the cylindrical drill body; the two gears are positioned between the top wall of the cylindrical drill body and the partition plate and are respectively connected with the rocker and the screw rod; the lower part of the rocker is connected with a gear, and the upper part of the rocker extends out of the top wall; the partition plate is positioned 10cm below the top wall of the cylindrical drill body and is parallel to the top wall; the screw rod is positioned in the cylindrical drill body, and the upper part of the screw rod is connected with the gear.

The utility model discloses a construction application method is: the rotary type auxiliary slag removal cylindrical drill is characterized in that during construction, the drill is in place according to a measured pile line, a cylindrical drill body is hoisted, then a flange is installed on the drill, and the rotary drilling rig is started; after the cylindrical drill body is fully squeezed with the drill slag, the cylindrical drill is lifted out; then the rocker at the upper part of the cylindrical drill is rotated, the rocker drives the gear, the gear drives the screw rod to rotate, the integrity of rock soil blocked in the cylindrical drill is damaged, and the drilling slag can be easily shaken out from the lower part.

The utility model discloses a theory of operation is: the supplementary scarfing cinder section of thick bamboo of rotation type bores, has viscidity ground often can bond and form a whole together in the work progress to lead to the drilling slag stifled difficult the droing in the section of thick bamboo brill, at this moment drive the screw rod through rotatory rocker and rotate together, produce the tangential thrust effect to the interior clay rubble of a brill section of thick bamboo, destroy the wholeness of boring the sediment in the section of thick bamboo brill, make the ground in the section of thick bamboo brill loose, at last the rig drives the section of thick bamboo brill and rocks, the sediment of boring in the section of thick bamboo brill will be shaken out easily.

The utility model has the advantages that: the rotary auxiliary slag removal barrel drill is not only suitable for construction units, but also suitable for surveying institutions, research institutions and the like, and is suitable for engineering operation of rock drilling by using the drill barrel. This utility model discloses an improve technical principle simply, the simple operation, the sexual valence relative altitude, the engineering practicality is strong, shakes it off easily through the wholeness that destroys the stickness ground, improves work efficiency, shortens construction cycle, can use widely on a large scale.
