Abstract
The invention relates to a protective cover structure for a drill pump, which comprises a protective cover plate arranged on a frame. At least one bolt is arranged on the protective cover plate which is connected with the frame through the bolt. The protective cover plate is connected with the frame through the bolt to replace the existing mode of connection through a rotation shaft, and when the protective cover plate is installed on the frame, users only need to enable the bolt to be screwed in a corresponding screw hole on the frame. The protective cover structure has the advantages of being simple in structure and convenient in assembly and disassembly.
Description
Technical field
The present invention relates to a kind of shroud structure, particularly a kind of shroud structure that is used for drilling pump.
Background technique
Existing drilling pump; For the purpose of dismounting and safety; Outside in the drilling pump frame; Be provided with shroud structure, shroud structure is arranged at the sidepiece of frame, and can see through the motion conditions of situation and intermediate draw bar that shroud structure observation is positioned at inner water quench cylinder sleeve, piston, piston rod, manger board, mudguard wing etc.
The shroud structure of traditional drilling pump sees also Fig. 1 to Fig. 3, mainly comprise bearing 5 ', axle 6 ', sheet frame 7 ', top board 8 ', heavy Mild Steel Expanded Sheets 9 ', the collar 10 ' and shake hands 11 ' etc., and above-mentioned parts is steel part.
Wherein, bearing 5 ' welds together with the frame of drilling pump; Axle 6 ', sheet frame 7 ', top board 8 ', heavy Mild Steel Expanded Sheets 9 ' are welded into a whole guard shield plate, and hinged through axle 6 ' and bearing 5 ', to realize its whole relatively rotating; The collar 10 ' also is welded on the whole guard shield plate with handle 11 ', and can whole guard shield plate be opened or cover around axle 6 ' upset through the operation handle.
But the employing said structure has following deficiency:
1, complex structure, dismounting difficulty;
Because dead weight is heavier, need during assembling bearing 5 ' is welded on the frame and with 6 ' coaxial packing into of axle, complicated operation and difficulty are big;
2, adopt heavy Mild Steel Expanded Sheets 9 ' to cut off, dustproof poor effect with extraneous;
Because the various dust in the drilling pump site environment can pollute the frame inner piece; Like intermediate draw bar, piston rod, manger board, cylinder sleeve, piston, cylinder sleeve gland etc.; Especially for mudguard wing parts and intermediate draw bar; The sealing part abrasion that the suction of dust can directly cause relatively moving between intermediate draw bar and the mudguard wing aggravates, and pollutes the lubricant oil of power end;
And grid causes obstruction to operator's sight line, is difficult to observe its inner case.
3, number of spare parts is many, and all is steel part, and overall weight is excessive.
Summary of the invention
The technical problem that the present invention solves is to overcome the above-mentioned deficiency of existing technology, and a kind of shroud structure that is used for drilling pump simple in structure, easy-to-mount is provided.
For solving the problems of the technologies described above, the invention provides following technological scheme:
