Abstract

The utility model relates to a pipe pile cutting machine used in the building industry, comprising a power unit, a transmission mechanism, a spindle and a cutting part which is arranged on the spindle and comprises a circular saw blade; the circular saw blade is fixedly clamped on the end of the spindle through a front chuck and a rear chuck; the spindle is also sleeved with a flow equalization piece capable of relatively rotating; a liquid-tight flow equalization cavity is arranged between the inner hole wall of the flow equalization piece and the spindle; the flow equalization cavity is provided with a water inlet nozzle; at least one surface of the front chuck and the rear chuck which is adhered with the circular saw blade is provided with spray waterway which extends from a central hole to the edge of the chuck and comprises a groove; and a conveying waterway which communicates the spray waterway and the flow equalization cavity is arranged in the spindle. When the pipe pile cutting machine cuts, because of the action of centrifugal force, cooling water flows out along the water inlet nozzle, the flow equalization cavity, the conveying waterway and the spray waterway and is diffused towards the edge of the outer side along the surface of the circular saw blade to cool the circular saw blade, thereby prolonging the service life of the circular saw blade and simultaneously wetting the powder produced in cutting so that the powder is not easily raised so as to greatly inhibit the dust and well protect an operator.

Description

A kind of pile tube cutting machine

Technical field

The utility model relates to the auxiliary cutting implement of a kind of building foundation engineering, specifically is exactly the pile tube cutting machine that is used for the pile crown of the concrete prefabricated pile tube of squeezing into ground is carried out cutting operation.

Background technology

The Foundation Design of modern project building all need be driven piles, and requires every section high unity that bassets after stake is driven underground, and then spreads steel mesh reinforcement in the above.And the height that the stake that pile driver is now laid is basseted is difficult to unanimity, and pile crown all has destruction in various degree, in order to keep unified height and quality, pile crown to be removed some, past all the time, remove this section and all be and cut by hand earlier or remove cement layer with pneumatic pick, remove the reinforcing bar that exposes with hacksaw or wind cutting mill again, benefit is extremely slow, quality is undesirable dangerous again, for this reason, the applicant is that the patent No. of on October 11st, 2006 bulletin is to disclose a kind of pile tube cutting machine in 200520070118.8 the utility model patent, its primary structure comprises motor, transmission mechanism, main shaft and be installed in cutting that the saw blade on the main shaft constitutes partly, saw blade is clamped to main shaft by the front and back chuck, and described cutting part is installed on the base, base is provided with bearing support, and main shaft is supported by bearing support.Described pile tube cutting machine also is provided with and is used for cutting part is connected pile ring on the pile crown, described pile ring comprise in one hoop and one be set in hoop go up and can do circumferentially outer in relative rotation the hoop, hoop and outer hoop constitute by a pair of semicircular ring pin joint together in described, evenly be provided with the adjustment screw that radially is provided with more than three groups on the circumference of interior hoop, described cutting part is hinged on the outer hoop rotationally, and turning cylinder is parallel with main shaft and perpendicular to interior hoop, bind round the plane, place outward.After this pile tube cutting machine cutting part is fixed on the pile crown by pile ring, can not produce relative displacement with pile crown at axial direction, but can pile crown be cut along circumferentially moving for axle by pile crown with outer hoop, therefore otch flushes, and the efficient height is safety again, pile ring adopts by a pair of semicircular ring pin joint structure together, loads and unloads very convenient.But after the mode of occupation feedback that this machine comes 2 years through the building site, also exist weak point more, promptly in cutting process, can produce a large amount of dust, and these dust granularities are very thin, sucked by the people easily, operator healthy brought very big harm.In addition, because rotation cutting at a high speed, the friction of saw blade and cement pile crown can make the saw blade heating, temperature can rise to Baidu, can not use as untimely cooling saw blade, this influence in application life to saw blade is very big, so the application life of saw blade is not long again.

The utility model content

The purpose of this utility model is to provide a kind of pile tube cutting machine of prolonging the application life of saw blade and can not produce a large amount of dust in cutting process of helping for overcoming the deficiencies in the prior art.

For achieving the above object, the technical solution that the utility model is taked is as follows: the pile tube cutting machine comprises power set, transmission mechanism, main shaft and is installed in the cutting part that the saw blade on the main shaft constitutes, saw blade is clamped to the end of main shaft by forward and backward chuck, described cutting part is installed on the base, base is provided with bearing support, and main shaft is supported by bearing support; Described pile tube cutting machine also is provided with and is used for cutting part is connected pile ring on the pile crown, cutting part is hinged on the outer hoop rotationally, it is characterized in that: also being arranged with one on the described main shaft can counterrotating current-sharing part, described current-sharing part is fixed on the base, be provided with the close current-sharing chamber of liquid between described current-sharing part inner hole wall and the main shaft, described current-sharing chamber is provided with into water water nozzle, chuck and back have at least in the chuck one to be provided with the spray water channel that extends to the groove formation at chuck edge from centre bore with face that saw blade pastes mutually before described, are provided with the conveying water channel that UNICOM sprays water channel and current-sharing chamber in the described main shaft.

Compared with prior art; owing on main shaft, also be arranged with the current-sharing part and carried water channel; and be provided with in the chuck in preceding chuck and back from centre bore and extend to the spray water channel that the groove at chuck edge constitutes; therefore after the water inlet water nozzle connects water pipe; when the pile tube cutting machine cuts; because the centrifugal action that the saw blade rotation produces; cooling water will be along the water inlet water nozzle; the current-sharing chamber; carry water channel and spray water channel to flow out; and scatter next along saw blade surface outward side fate; saw blade is cooled off; to cut the powder that produces simultaneously drenches; it can not be kicked up easily; therefore suppress the generation of dust widely, protected the operator well.

As further setting of the present utility model, described before chuck and afterwards be equipped with the spray water channel on chuck and the face that saw blade pastes mutually.Can make the both side surface of saw blade can both obtain simultaneously the cooling of cooling water like this, improve cooling effect.

Further be provided with as of the present utility model, described spray water channel constitutes by annular recess with some the radial grooves that are radial setting of described annular recess UNICOM again, near the chuck edge for being the radial groove of radial setting.Can make the more uniform cooling that obtains of saw blade like this, improve cooling effect.

Further be provided with as of the present utility model, described current-sharing part and bearing support are for being wholely set.Preferably the side at bearing support is provided with the boss platform, and the boss center is provided with the axis hole of diameter greater than the main shaft diameter, and described main shaft passes axis hole, and described axis hole two ends are provided with annular oil seal, and the space that described main shaft, axis hole and annular oil seal sealed constitutes described current-sharing chamber.Can make structure compact like this.
