Abstract
The utility model discloses a specialized tool of dismouting compressor main shaft tile who uses in the coal bed gas production comprises support frame, U type bracket, gasket and promotion nut. Have two logical grooves of lining up from top to bottom above the support frame, there are two stoppers the bottom surface. The upper end of U type bracket is threaded, and there is the layer board bottom of lower extreme U type. Promote nut and gasket can with the screw -thread fit of U type bracket upper end. It can be steadily, the quick safe bent axle in the compressor crankshaft case of mentioning, then the operation workman just can maintain or change the main shaft tile according to main shaft actual conditions made of baked clay. Owing to need not put forward the bent axle inside the crankcase, just also need not employ jack -up instruments such as crane, so operating speed is fast, the security is high, and intensity of labour is little.
Description
Technical field
The utility model discloses during a kind of coal bed gas is produced the specific purpose tool of the dismounting compressor main shaft watt used.
Background technology
In coal bed gas and gas extraction and conveying operation, need the pressure improving extraction gas with compressor, so that carry in air delivering pipeline.Compressor wants periodic maintenance and maintenance in routine duties, " repair and maintenance handbook " requires maintenance inspection in every 8000 hours main spindle box bearing clearance, so operating personnel need to check main bearing shell with or without wearing and tearing, eccentric wear, cellularly to come off, fall layer etc., also to change the main bearing shell of damage when pinpointing the problems in time.Because the bent axle of compressor is very heavy, precision is higher again, therefore checks or to change the main bearing shell tightly pushed down by bent axle comparatively difficult.All that the bent axle of compressor is hung out crankcase by investigation mission outside the city or town lifting working platform door crane in the past, then operating personnel carry out checking or changing main-spindle watt again, not only formality is loaded down with trivial details, take personnel equipment many, operating time is long, and hoisting operation also has certain danger to the personal safety of equipment and operating personnel.
Summary of the invention
The purpose of this utility model be openly a kind of can the specific purpose tool of dismounting compressor main shaft steadily, fast and safely watt.It steadily, fast and safely can mention the bent axle in compressor crankcase, and then operator just can carry out maintaining or changing main-spindle watt according to the actual conditions of main bearing shell.
For achieving the above object, the utility model is made up of bracing frame, U-shaped bracket, pad and hoisting nut.Have the groove of two up/down perforations above support frame as described above, there are two limited blocks bottom surface.There is screw thread the upper end of U-shaped bracket, and supporting plate is arranged at U-shaped bottom, lower end.Hoisting nut and pad can with the threaded engagement of U-shaped bracket upper end.
After having adopted said structure, the bottom of one end of U-shaped bracket from the bent axle in compressor crankcase can be passed by operator, the supporting plate of U-shaped bracket lower end is made to hold bent axle, and then ridden on the end face of crankcase horizontal for bracing frame, after the groove being thread through on bracing frame of U-shaped bracket upper end, screw on pad and hoisting nut.Be arranged on crankcase with coordinating before and after the specific purpose tool of two cover dismounting compressor main shafts watt, evenly tighten each hoisting nut, bent axle will be lifted to the height of needs reposefully by U-shaped bracket, then operator just can take out the latter half of the dissection type main bearing shell that be press against by bent axle like a cork, next can carry out maintaining or changing main-spindle watt according to the actual conditions of main bearing shell.Owing to not needing that bent axle is put forward inside crankcase, also just need not employ the lifting gears such as crane, therefore service speed is fast, and security is high, and labour intensity is little.
Accompanying drawing explanation
Fig. 1 is the operating diagram of a detailed description of the invention of the specific purpose tool of the utility model dismounting compressor main shaft watt.
Fig. 2 is the top view of the operating diagram of the specific purpose tool of the utility model dismounting compressor main shaft watt.
Detailed description of the invention
Be described in further detail below in conjunction with the specific purpose tool of accompanying drawing to the utility model dismounting compressor main shaft watt.As shown in Figure 1, the utility model is made up of bracing frame 4, U-shaped bracket 6, pad 3 and hoisting nut 2.Support frame as described above 4 has the groove 11 of two up/down perforations above, and there are two limited blocks 5 bottom surface.There is screw thread 1 upper end of U-shaped bracket 6, and supporting plate 8 is arranged at U-shaped bottom, lower end.Hoisting nut 2 and pad 3 can coordinate with the screw thread 1 of U-shaped bracket 6 upper end.
When needing to maintain the main bearing shell 10 of compressor or change, first the top cover of crankcase 9 can be unloaded, again the bottom of U-shaped bracket 6 from the bent axle 7 in compressor crankcase 9 is passed, the supporting plate 8 of U-shaped bracket 6 lower end is made to hold bent axle 7, and then on horizontal for bracing frame 4 end face riding over crankcase 9, the screw thread 1 of U-shaped bracket 6 upper end through after the groove 11 on bracing frame 4, screw on pad 3 and hoisting nut 2.Be arranged on crankcase 9 with coordinating before and after the specific purpose tool of two cover dismounting compressor main shafts watt, evenly tighten each hoisting nut 2, bent axle 7 will be lifted to the height of needs reposefully by U-shaped bracket 6, then operator just can take out the latter half of the dissection type main bearing shell 10 that be press against by bent axle 7 like a cork, next can carry out maintaining according to the actual conditions of main bearing shell 10 or changing main-spindle watts 10.Owing to not needing that bent axle 7 is put forward inside crankcase 9, also just need not employ the lifting gears such as crane, it also avoid to the collision of bent axle 7 and wearing and tearing in the process of lifting bent axle 7, therefore service speed is fast, and security is high, and labour intensity is little simultaneously.
