Abstract
The utility model discloses a pneumatic switching device of mining explosion-proof diesel engine, be equipped with the valve body of valve block in including, the connecting plate of being connected with the valve body, pass the pivot of connecting plate, connecting rod and with connecting rod one end articulated piston rod, the both ends of pivot respectively with valve block and connecting rod fixed connection, still include with the cylinder that the piston rod links to each other, the cylinder passes through the pin rod to be fixed on the connecting plate. The pneumatic switch device of the mining explosion-proof diesel engine further comprises a first limiting screw and a second limiting screw which are used for limiting the rotation angle of the connecting rod, and the first limiting screw and the second limiting screw are fixed on the connecting plate. The utility model has the advantages of being simple in structure and convenient in operation, adopt behind pneumatic mode control flap's the switch, not only avoided the shortcoming that flame proof electro-magnet heat generation is high, factor of safety is low, guarantee simultaneously under the state that does not have the air supply, the diesel engine can't start to make security performance greatly increased.
Description
Technical field
The utility model relates to Pneumatic unlocking and closing apparatus, relates in particular to a kind of anti-explosion diesel engine for mine Pneumatic unlocking and closing apparatus.
Background technique
The employed switch gear of anti-explosion diesel engine for mine is generally flame proof magnet control mode at present, and control valve is open in usual.But flame proof magnet control mode adds the vibrations in the working process of diesel engine because heating value is high, causes its working life very short; And when adopting control valve open in usual, once power supply is malfunctioning, anti-explosion diesel engine just can't be closed, so safety coefficient is lower.Just because of above reason, so that the anti-explosion diesel engine for mine rate of fault is high, use thereby impact is normal.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, easy to operate and safe and reliable anti-explosion diesel engine for mine Pneumatic unlocking and closing apparatus in order to overcome above-mentioned deficiency.
In comprising, the utility model is provided with the valve body of valve block, the connecting plate that is connected with valve body, the rotating shaft of passing connecting plate, connecting rod and the piston rod hinged with connecting rod one end, the two ends of described rotating shaft are fixedly connected with connecting rod with valve block respectively, also comprise the cylinder that links to each other with described piston rod, described cylinder is fixed on the connecting plate by pin rod.
Described anti-explosion diesel engine for mine Pneumatic unlocking and closing apparatus comprises that also be used to the first stop screw that limits described connecting rod rotation angle, described the first stop screw is fixed on the connecting plate.
Described anti-explosion diesel engine for mine Pneumatic unlocking and closing apparatus comprises that also be used to the second stop screw that limits described connecting rod rotation angle, described the second stop screw is fixed on the connecting plate.
The utility model is simple in structure, easy to operate, after adopting the switch of pneumatic mode control valve, not only avoided the shortcoming that flame proof electromagnet heating value is high, safety coefficient is low, guaranteed simultaneously under the state that does not have the source of the gas supply, diesel engine can't start, thereby Safety performance is increased greatly.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1-valve body (11-valve block), 2-rotating shaft, 3-connecting plate, 4-connecting rod, 5-piston rod, 6-cylinder (61-suction port), 7-the first stop screw, 8-pin rod, 9-the second stop screw.
Embodiment
Further specify the utility model below in conjunction with drawings and Examples.
Embodiment: be provided with the valve body 1 of valve block 11, the connecting plate 3 that is connected with valve body 1, the rotating shaft 2 of passing connecting plate 3, connecting rod 4 and the piston rod 5 hinged with connecting rod 4 one ends in the utility model comprises, the two ends of described rotating shaft 2 are fixedly connected with connecting rod 4 with valve block 11 respectively, also comprise the cylinder 6 that links to each other with described piston rod 5, described cylinder 6 is provided with suction port 61, and cylinder 6 is fixed on the connecting plate 3 by pin rod 8.Comprise that also be used to the first stop screw 7 that limits described connecting rod 4 rotation angles and the second stop screw 9, described the first stop screw 7 and the second stop screw 9 are fixed on the connecting plate 3.
During use, by suction port 61 to cylinder 6 interior air feed, then cylinder 6 pushing piston bars 5 motions, piston rod 5 promotes connecting rod 4 and rotates, thereby drive rotating shaft 2 rotations, so just the valve block 11 that links to each other with rotating shaft 2 can be opened several angle, when connecting rod 4 turns to when contacting with the first stop screw 7, valve block 11 is in maximum angle, and at this moment the diesel engine intake pipeline is unimpeded, when stopping air feed, cylinder 6 backhauls, the angle that connecting rod 4 rotated when the second stop screw 9 can limit backhaul, valve block 11 namely is in closed condition, and the diesel engine intake pipeline is blocked and just can't starts.
