The utility model comprises a driving mechanism, a control mechanism and a cooling mechanism, and is characterized in that the driving mechanism is driven by a hydraulic motor, a control ball valve, a switch handle and a saw blade are arranged in the control mechanism, and the cooling mechanism cools the saw blade through a return liquid split-flow valve and a spray pipe. The hand-held hydraulic saw has advantages of reliable and convenient use and movement, ensuring the safety of explosion prevention in the process of operation, being capable of adopting different cutting velocities according to different cutting materials and broad adaptability.
Description
Technical field
The utility model relates to the hand-held hydraulic saw of a kind of explosion-proof type, be applicable in the hydraulic system of various types, comprise mineral oil, water-based emulsion liquid, oil base emulsion, water-ethylene glycol fire resistant liquid etc., be specially adapted to high-water-based emulsion system under the coal mine, the working environment that when adopting the flame retardancy working media, can be applied to have requirement of explosion proof, the saw blade that cooperates unlike material carries out the cutting of various materials such as metal, nonmetal, material, paper.
Background technology
The hand-held hydraulic saw product that present circular diamond saw blade that uses or abrasive material saw blade carry out the material cutting all adopts Motor Drive, only is used for the material cutting of ground environment.When being applied to the inferior high-risk adverse circumstances of coal mine following times, the hand-held hydraulic saw that drives by common motor does not just have explosion-proof performance; And except that the motor factor, the generation of the heating of saw blade and cutting spark also makes it to be applied to the occasion of contour explosion danger under the coal mine in cutting process; Common motor works under the rated speed simultaneously, and the cutting speed of hand-held hydraulic saw can't be adjusted according to material, has also influenced the scope of application of hand-held hydraulic saw, and then because the cost of motor and control element is higher, still nobody adopts variable-speed motor.
The utility model purpose
The purpose of this utility model is exactly will provide in a kind of hydraulic system that is applicable to various types, is specially adapted to high-water-based emulsion system under the coal mine, can be applicable to have the hand-held hydraulic saw of explosion-proof type in the working environment of requirement of explosion proof.
The utility model content
The purpose of this utility model is achieved in that the utility model is made up of driving mechanism, operating mechanism and cooling body, it is characterized in that driving mechanism is by fluid motor-driven, manipulation ball valve in the operating mechanism is installed in the inlet of hydraulic motor, switch knob is installed on the housing of motor, motor output shaft is provided with saw blade, time liquid flow divider in the cooling body is installed in the liquid outlet of hydraulic motor, shower one end is installed on the flow divider, the other end points to saw blade, and protective cover is installed on the end face of hydraulic motor output shaft one side.
Distinguishing feature
Distinguishing feature of the present utility model is:
1, drive unit adopt fire resistant liquid medium such as emulsion hydraulic motor as dynamical element, need not to connect electricity, do not have any electrical equipment yet, make band saw itself have intrinsic safety; With take snap joint design being connected of working media pipeline, guarantee hand-held hydraulic saw use with move reliable and convenient;
2, cooling device is formed by returning liquid flow divider and shower, difficulties such as the emulsion combustion medium that utilizes a part to reflux reaches the cooling saw blade by shower spray saw blade and workpiece and eliminates the purpose of cutting spark, guaranteed the explosion-proof security of operation process, the flow of spray working solution can be adjusted;
3, manipulation device is made up of switch knob that has speed-regulating function and manipulation ball valve, can take different cutting speeds according to the difference of cutting material, has adaptability widely.
4, in various job sites, special in the environment of the contour explosion danger in colliery, the work requirements that lot of materials cutting aspect is arranged, expose the cutting of bar head as anchor metal, the conveyor chain cutting, the destructiveness cuttings of the nut that can't dismantle etc. can't realize the mechanization operation because of lacking the portable cutting equipment of explosion-proof type at present.The utility model will effectively solve actual demand.
5, anchor metal is exposed the first-class cutting of bar, conveyor chain cutting, the cutting operation that the destructiveness cutting of the nut that can't dismantle etc. need be carried out at the scene, down-hole is improved to the mechanization operation by handwork, can raise labour efficiency greatly, not be reduced to less than 1 minute as not waiting by 30 to 60 minutes break time of a conveyor chain.
6, promote the security of cutting work, even because handwork also produces spark inevitably when cutting metal material, from still not possessing security in essence, the utility model has then reached intrinsic safety by the fire resistant liquid spray equipment.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
The utility model is made up of driving mechanism, operating mechanism and cooling body, and the core component of complete machine is a hydraulic motor; Protective cover is installed on the end face of hydraulic motor output shaft one side with bolt; Saw blade is installed on the hydraulic motor output shaft with trip bolt; Switch knob is installed on the housing of hydraulic motor with bolt; Leverage in the operating mechanism is installed on the handle, handles ball valve and is installed in the inlet of hydraulic motor; The liquid flow divider that returns in the cooling body is installed in the liquid outlet of hydraulic motor, and shower one end is installed on the flow divider, and the other end points to saw blade.
Structure of the present utility model as shown in Figure 1, handle 1, controlling organization 2, hydraulic motor 3, cooling body 4, saw blade 5, trip bolt 6 and protective cover 7.Drive unit of the present utility model is a hydraulic motor 3, and saw blade 5 usefulness trip bolts 7 are fastened on the output shaft end of hydraulic motor 3.After the manipulation ball valve 11 of working media in manipulation device entered hydraulic motor 3, hydraulic motor 3 carried out gyration under the high-pressure medium effect, and band saw blade 5 rotates finishes cutting operation.
Manipulation device of the present utility model pull bar 8, lever 9, is adjusted bolt 10, ball valve core 11, is handled ball valve 12 and inlet 13 as shown in Figure 2.Handling ball valve 12 is installed in the motor inlet 13.Pulling pull bar 8 drives lever 9 during operation, makes the adjustment bolt 10 of end depress the spool 11 of handling ball valve 12, and ball valve is open-minded, and high-pressure working medium enters hydraulic motor 3 by inlet 13 through handling ball valve 12, drives hydraulic motor 3 work.After pull bar 8 discharged, the spool 11 of handling ball valve 12 automatically reset under the effect of contained spring, closed and handled ball valve 12, and saw blade 5 stops operating.Inlet 13 can adopt the K type hydraulic quick coupler of coal in China industry standard, also can adopt the joint of other patterns.
