Description
Technical field
The present invention relates to a kind of mining hydraulic chain grooving apparatus, be specially hydraulic chain grooving machine, especially can be widely used in engineering and mine formation hardness≤12Mpa, depth of cut is not more than the various soft or hard rocks cuttings of 450mm and the auxiliary fluting work of shallow bore hole of half coal rock tunnel.
Background technology
As everyone knows, the building construction of the airtight body of wall of ventilation is the conventional a large amount of element task of ventilating management under the coal mine, being the important means of rationally regulating and control mine and operation place fresh air volume, also is to prevent coal dust, gas explosion and other pernicious gas effective technical way to personnel's mortal injury.Along with the continuous growth of China to the demand of coal resources, the coal mining amount is in fast lifting, and the safety code of " with the wind fixed output quota " requires the increasing that must bring ventilating engineering.And domestic most of coal mine roadway air door is installed and the notch excavation work of tunnel sealing, usually adopt artificial slotting or electric rock drill, pneumatic pick auxiliary construction, not only there are problems such as labor strength is big, activity duration length, inefficiency in this manual work mode, and section Forming Quality body of wall poor, that be built into easily collapses, a little less than sealing difference and the persistence, there is certain potential safety hazard, and a series of accidents such as gas explosion that cause thus are also of common occurrence, not only cause casualties, and bring the certain economic loss for colliery and country.
Summary of the invention
The present invention is in order to overcome the defective that existing artificial channeling or electric rock drill, pneumatic pick auxiliary construction exist at aspects such as working procedure, quality, precision and efficient, and a kind of efficient height, precision is accurate and volume is little hydraulic chain grooving machine are provided.
The present invention adopts following technical scheme to realize: multi-functional chain grooving machine, comprise frame, terminal setting operation handle of frame and the control trigger that is connected and has trigger with operating grip, the control trigger is connected with hydraulic control valve, and hydraulic control valve and frame are interior and be connected by the hydraulic motor of hydraulic power unit driving; Central rack is provided with handrail, drive sprocket is housed on the hydraulic motor output shaft, frame front is equipped with the saw plate that is positioned at same horizontal plane with drive sprocket, the saw plate is three-layer combined structure, the saw front edge of board back shaft is set between the top layer up and down, driven sprocket is housed on the back shaft, and the saw chain that the border is provided with cutting head serves as to support on the drive sprocket and driven sprocket that is nested in saw plate two ends with the saw plate; On the saw plate water inlet and the delivery port that interconnects by guiding gutter is set, saw plate below is provided with the water inlet pipe that communicates with water inlet.Saw plate of the present invention is to be made of by riveted and welded mode upper epidermis, intermediate layer, following top layer, and the intermediate layer is longer than on the top layer up and down of saw front edge of board slightly, and its length that exceeds depends on the size of driven sprocket.On the saw plate of the present invention water inlet and delivery port are set, the clean water that possesses certain pressure is entered by water inlet, then by saw on the plate guiding gutter after delivery port flow out, the saw chain that is rotated at a high speed during outflow is transformed into spray water and is ejected on cutting object and the saw chain, generate heat thereby reach because of the main frame long-play causes various mechanical fittings, influence the purpose in normal application life, also eliminated simultaneously saw chain and rotated the safe construction hidden danger and the accident harm that cause or cause at a high speed with being cut that the fricative spark of object and extraneous unsafe factor meet, and the dust atmosphere that work produces polluted play the depositing dust effect, reached the explosion-proof of colliery underground equipment, the dustproof instructions for use.The present invention adopts on the saw plate two water inlets and six delivery ports is set, two water inlet pipes of corresponding setting below the saw plate.Cutting head of the present invention is welded on the saw chain border by laser welding process, can be diamond or carbide alloy, can select different cutting heads for use according to the difference that is cut the object material.
Adopt structure design of the present invention, hydraulic motor is connected with hydraulic power unit, cooling water source is connected with water inlet pipe, start hydraulic power unit then, open the cooling water source switch, hydraulic power unit drives hydraulic motor and rotates under the drive of motor, thereby do the high speed linear motion by saw chain and saw plate that drive sprocket is connected with driven sprocket with hydraulic motor, realization is to the cutting of coal and rock, cooling water is introduced in the guiding gutter of sawing in the plate by water inlet simultaneously, flow out through delivery port then, the saw chain that is rotated at a high speed during outflow is transformed into spray water and is ejected on cutting object and the saw chain, has solved saw chain and has rotated at a high speed and be cut object friction and produce spark, the problem of intensification and airborne dust.Center of gravity was near human body when the present invention considered groover propped up, and laborsaving being convenient to again controlled, and meets the human body operating mode, so the groover overall structural arrangement is become the front and back order, the shape that be that the left and right sides is narrow, front and back is long forms laminar layout, singlely or double all is convenient to operation.Saw chain of the present invention and saw plate are with the centre type that is in line, and circular transitional structure mode is adopted at two ends, under the prerequisite that does not increase physical dimension, increases depth of cut.
The front lower place of frame of the present invention is provided with the auxiliary stand that flexibly connects with frame, and auxiliary stand can rotate around frame.The present invention considers that the downhole operations personnel are in the standing state operate equipment, and equipment is when placing the position, front, the application of force is relatively more difficult downwards, and the effect of auxiliary stand is to convert groover motion and strength forward to the downward motion of saw chain and cutting force, only need push ahead when making cutting and just can realize moving and motion of both direction, its mechanical forces transformation ratio is 4: 1.This kind structure is that the those of ordinary skill of mechanical field is known.
On frame of the present invention and the saw plate protective cover is set respectively, prevents that the chance failure of drive sprocket and saw chain from causing personal injury to the operator, protected personal safety to a certain extent.
Frame of the present invention front upper place is provided with dashboard, is used to stop the disintegrating slag, the mud that are cut object to be ejected into human body and main frame.
Handrail of the present invention end is provided with the handrail backplate, and handled easily is also laborsaving, can play the effect of protection operator hand simultaneously.
