Abstract
The utility model discloses a slime pump with a split flip cover pump structure. The slime pump comprises a split flip cover pump body 6, a crankshaft 2, a connecting rod 3, a crosshead 4 and a bearing 5, wherein the split flip cover pump body 6 comprises a lower pump body 6-1 and a pump body upper cover 6-2; the pump body upper cover 6-2 is mountedon the lower pump body 6-1 through a bolt; the crankshaft 2 is supported and mountedon a journal 6-1-3 on two sides of the lower pump body 6-1 through the bearing 5; the connecting rod 3 is mountedon the crankshaft 2, and a small head end 3-2 of the connecting rod 3 is connected with the crosshead 4; the crosshead 4 is mountedbetween a crosshead slideway 6-1-2 in the lower pump body 6-1 and a crosshead slideway 6-2-1 in the bottom surface of the pump body upper cover 6-2. Because the pump body upper cover can be detached from the pump body, the upper part of the crosshead slideway is not blocked during assembly, after the pump body is assembled in a horizontal state, the pump body upper cover is mountedon the lower pump body, and the slime pump is convenient to detach. Moreover, the size of a supporting rib rod can be large, so the strength is high, and the safety of the whole slime pump is improved.
Description
Technical field
The utility model relates to geological drilling field, particularly a kind of slurry pump of split drawing-pushing type pump body structure.
Background technique
In geological drilling industry, the piston high-density pump equipment that is absolutely necessary.Existing slurry pump is the slurry pump of integrated type pump body structure, its structure as shown in Figure 1, 2, comprise the pump housing 1, bent axle 2, connecting rod 3, crosshead 4 and bearing 5, bent axle 2 is arranged on the axle journal 1-1 of the pump housing 1 both sides by bearing 5 supportings, connecting rod 3 comprises that stub end 3-1 and microcephaly hold 3-2, and be arranged on bent axle 2 by the axis hole being positioned on stub end 3-1, its microcephaly holds 3-2 to be connected with crosshead 4 by bearing pin, and crosshead 4 is arranged on the crosshead slideway 1-2 of the pump housing 1.When slurry pump is worked, 2 rotations of external impetus band dynamic crankshaft, bent axle drivening rod stub end 3-1 moves in a circle, and its microcephaly holds 3-2 to drive crosshead 4 to do linear reciprocating motion on crosshead slideway 1-2, and crosshead 4 drives other component motion on slurry pump again.
The slurry pump of this integrated type pump body structure, when assembling, must first be assembled into an assembly by connecting rod 3, bent axle 2 and crosshead 4, then this assembly and the pump housing 1 are assembled.As shown in Figure 3, when mud pump size is larger, the weight of described assembly is also very large for its assembling condition schematic diagram, crosshead 4 be packed into sidewards in the crosshead slideway 1-2 on the pump housing 1 difficult especially.For convenient for assembly, conventionally the pump housing 1 need to be holded up, that is: crosshead slideway 1-2 is become to vertical state from level.But under this state, each crosshead 4 is different at the effect upper/lower positions of connecting rod gravity, what have is not over against crosshead slideway 1-2, therefore each crosshead 4 will be packed on the pump housing 1 and still quite bother in corresponding crosshead slideway 1-2.In addition, the supporting rib bar 1-3 on the pump housing 1 is because will reserve enough spaces passes through for crosshead 4, and its size is less, and tenacity is poor, easily produces trickle distortion, and the safe operation of whole slurry pump is produced to harmful effect.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of slurry pump of split drawing-pushing type pump body structure is provided, and it can assemble under the state of horizontal positioned, and assembling difficulty is low.
The technical solution of the utility model is: a kind of slurry pump of split drawing-pushing type pump body structure, comprises the split drawing-pushing type pump housing, bent axle, connecting rod, crosshead and bearing; The split drawing-pushing type pump housing comprises lower pump body and pump body top cover, has supporting rib bar, crosshead slideway and axle journal on lower pump body, and there is crosshead slideway the bottom surface of pump body top cover, and it is arranged on lower pump body by bolt; Bent axle supports on the axle journal that is arranged on lower pump body both sides by bearing, connecting rod is arranged on bent axle by the axis hole being positioned on stub end, its little head end is connected with crosshead by bearing pin, and crosshead is arranged between the crosshead slideway and the crosshead slideway of pump body top cover bottom surface on lower pump body.
The further technological scheme of the utility model is: in lower pump body and pump body top cover, have mount pin axis hole.
The utility model further technological scheme is: in pump body top cover, be useful on the projection being connected with supporting rib bar upper end on lower pump body, mount pin axis hole is positioned on projection.
The utility model, because the pump housing adopts split drawing-pushing type structure, compared with prior art, has following features:
1, pump body top cover can disassemble from lower pump body, and during assembling, crosshead slideway top is unobstructed, and the pump housing is arranged on pump body top cover on lower pump body after can assembling under level, and the mounting or dismounting of slurry pump are all very convenient.
2, because the pump housing can be assembled under level, supporting rib bar on the pump housing, without being whole crosshead by reserved enough width, only needs the thickness of reserved connecting rod, therefore that the size of supporting rib bar can be accomplished is larger, therefore intensity is also better, promoted the Security of whole slurry pump.
Below in conjunction with figure and embodiment, detailed structure of the present utility model is further described.
