Cooled coal gas adds press main shaft conical surface alignment pin quick-release arrangement
Technical field
The utility model relates to a kind of cooled coal gas and adds press main shaft conical surface alignment pin quick-release arrangement.
Background technology
The effect that cooled coal gas adds press is after coal gas cools off in the cooled coal gas washer, to be compressed into elevated pressures and to offer the cooled coal gas user.Cooled coal gas adds press and is driven by high-voltage motor usually, gives compressor by reduction gear box with transmission of power.Wherein cooled coal gas adds the mode that adopts flange to connect that connects between press main shaft and the reduction gear box output shaft, and adopt conical surface alignment pin to fix between two connecting flanges, the latter half of conical surface alignment pin is with garden column type rubber tube, the first half is a cone, and the first half cone of conical surface alignment pin and the latter half rubber tube embed respectively in two conical surface pin installing holes of two connecting flanges.The purpose that the latter half of conical surface alignment pin is with garden column type rubber tube is that conical surface alignment pin is subjected to mechanical shock and damages when preventing compressor start or reduction gear box because of the mechanical breakdown all standing.
When cooled coal gas adds maintenance of press off-line or reduction gear box trouble hunting, need dismantle the connecting flange that cooled coal gas adds between press main shaft and the reduction gear box output shaft.As depicted in figs. 1 and 2, cooled coal gas adds between the flange 21 of the flange 11 of press main shaft 1 and reduction gear box output shaft 2 and adopts 12 conical surface alignment pins 3 fixing altogether, wherein six conical surface alignment pins add press main shaft connecting flange 11 fixing holes by cooled coal gas and penetrate, cone passes at reduction gear box output shaft connecting flange 21 fixing holes, and adopts bolt 31 fastening fixing; Other six conical surface alignment pins are penetrated by reduction gear box output shaft connecting flange 21 fixing holes, cone adds press main shaft connecting flange 11 fixing holes at cooled coal gas and passes, the same bolt 31 that adopts is fastening fixing, and 12 conical surface alignment pins 3 adopt positive and negative spaced mode to fix two connecting flanges 11,21.Since from penetrate by reduction gear box output shaft connecting flange 21 fixing holes, that cooled coal gas adds the conical surface alignment pin top that press main shaft connecting flange 11 fixing holes pass is limited from distance, position that cooled coal gas adds the press body, conical surface alignment pin field-strip difficulty is bigger, consuming time longer, postponed the normal operation of equipment, upkeep operation carries out in the coal gas zone simultaneously, and the long operation of maintainer also brings certain potential safety hazard.
Usually conical surface alignment pin takes traditional operational method to dismantle, by hammering conical surface alignment pin top, because the limitation of device location, can't exert oneself during the hammering alignment pin, prolonged the field-strip time greatly, caused certain work difficulty and working strength, if because during the improper generation of hammering distortion, then must take the other technologies means to carry out field-strip, the repair time can be longer like this.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of cooled coal gas and adds press main shaft conical surface alignment pin quick-release arrangement, this device has overcome the defective of traditional field-strip, can carry out the dismounting of conical surface alignment pin easily, shortened the activity duration of dismounting, reduced the labour intensity of dismounting, improve operating efficiency, guaranteed the safety of field-strip and the normal operation that cooled coal gas adds press.
For solving the problems of the technologies described above, the utility model cooled coal gas adds press main shaft conical surface alignment pin quick-release arrangement and comprises base plate, first side plate, second side plate, two bolt and nuts and roof pressure bolt, described first side plate and the second side plate perpendicular separation are located at described base plate both sides and end face is the indent arcwall face, the described first side plate center has screw, the described first side plate screw both sides have two first long lumbar holes, described roof pressure bolt is twisted in the screw of described first side plate, the described second side plate center has through hole, the described second side plate through-hole both sides have two second long lumbar holes with first side plate, the first long lumbar hole location matches, and described two bolts are fixed by nut after penetrating described two first long lumbar holes and second long lumbar hole respectively.
For ease of breaking away from behind the conical surface alignment pin roof pressure, the screw of above-mentioned first side plate is concentric with the through hole of second side plate.
On connecting flange, two first long lumbar holes of above-mentioned first side plate are concentric with two second long lumbar holes of second side plate for ease of two bolting.
Because the utility model cooled coal gas adds press main shaft conical surface alignment pin quick-release arrangement and has adopted technique scheme, promptly first side plate and the second side plate perpendicular separation are located at the base plate both sides and end face is the indent arcwall face, the first side plate center has screw, the first side plate screw both sides have first long lumbar hole, the roof pressure bolt is twisted in the screw of first side plate, the second side plate center has through hole, the second side plate through-hole both sides have second long lumbar hole with first side plate, the first long lumbar hole location matches, fix by nut after two bolts penetrate two first long lumbar holes and second long lumbar hole respectively.This device has overcome the defective of traditional field-strip, can carry out the dismounting of conical surface alignment pin easily, shorten the activity duration of dismounting, reduce the labour intensity of dismounting, improve operating efficiency, guaranteed the safety of field-strip and the normal operation that cooled coal gas adds press.
