Abstract
The utility model relates to a kind of crank journal assembling overhead hoist of shipbuilding industry bent axle assembling use, main body is handling support, clamping band and the turnbuckle for regulating, clamping band is by crank journal part, handling support hangs on crane by lifting rope, turnbuckle is connected between handling support and clamping band, after slinging, the crank journal vertical state of ascending the throne, by the fine adjustments of three turnbuckles, can accurately regulate the vertical state of crank journal.
Description
Technical field
The utility model relates to a kind of overhead hoist, particularly the overhead hoist of shipbuilding industry bent axle assembling use.
Background technology
In shipbuilding industry, the assembling of high-power low speed diesel engine semi-built-up crankshaft adopts the method for vertical hot jacket, and wherein the list that is assembled into of crank journal and crank overlaps operation, crank journal vertically need to be inserted in the hole of crank.Because the gap in axle and hole is very little, only have when the axis in axle and hole is vertically and when concentric, could assemble smoothly.Crank is to be fixed on workplatform, crank journal need to be sling, and accurate adjustment is vertical state.If adopt conventional suspender belt binding method to be difficult to crank journal to hang into vertical state, accurately adjust squareness just more difficult.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of suspender crank journal vertically can be sling, and can the vertical state of fine adjustment.
The technical scheme that the utility model solves this technical problem employing is: a kind of crank journal overhead hoist, base portion is followed successively by from top to bottom handling support, regulates parts, crank journal clamping band.Handling support with equilateral triangle shape, be uniformly distributed three hangers respectively up and down, upper hanger connecting hanging rope, lower hanger connects one end of turnbuckle; Regulate part to form with the uniform equally turnbuckle of handling support by three; Crank journal clamping band is sling for the clamping of crank journal part, clamping band be shaped as two semicircles, be tightened by bolts circle of rear formation by crank journal banding, on its circumference, be uniformly distributed three hangers, be connected with the other end of turnbuckle.
Clamping band is embraced crank journal outer toroid, and after slinging, crank journal is in vertical state.The rotatable adjustment length of turnbuckle, by regulating the length of three turnbuckles, the length distance of three positions between handling support and clamping band is changed, can make the swing that crank journal is small, the accurate adjusting of realization to crank journal squareness, the squareness data of crank journal can be measured by placing level indicator at its end face.
Accompanying drawing explanation
Fig. 1 is the utility model schematic perspective view.
Fig. 2 is that the utility model solid is broken up figure.
Fig. 3 is clamping band birds-eye view.
In Fig. 1 ~ 3: 1. lifting rope, 2. handling support, 3. turnbuckle, 4. clamping band, 5. lock bolt, 6. crank journal part, 7. clamping band hanger, 8. descend hanger, 9. go up hanger.
The specific embodiment
Below in conjunction with accompanying drawing and example, the present invention is described in further detail.
First two semi-circular clamping bands (4) are encircled to the middle shaft part cylindrical at crank journal part (6), and the conglobate hoop of shape after locking with lock bolt (5).At the even circumferential of clamping band (4) three hangers that distribute, two clamping band hangers (7) wherein, a lock bolt (5) is used as hanger.One end of three turnbuckles (3) is contained on the hanger of clamping band (4), the other end of turnbuckle (3) is connected to the lower hanger (8) of handling support (2), three lifting ropes (1) are connected to the upper hanger (9) of handling support, and three lifting ropes (1) are hung on crane and sling.
Crank journal part (6) is vertical state after slinging, by rotating respectively three turnbuckles (3), vertical state to crank journal part (6) carries out fine adjustment, can on the end face of crank journal part (6), place level indicator and carry out its vertical state of Measurement accuracy during adjusting.
While lifting operation, only need locking, unclamp clamping band (4), can complete installation, the dismounting of the overhead hoist of crank journal part (6); Trace by three turnbuckles regulates, and can complete the accurate adjustment of squareness, lifts convenient to operation.
Claims (2)
1. crank journal assembles overhead hoist, and main body is handling support (2) and clamping band (4), it is characterized in that: handling support (2) has respectively three hangers (8,9) up and down, and upper hanger (9) connects lifting rope (1); Clamping band (4) is two semicircles, by lock bolt (5), connects to form circular clip, at three hangers of circumference uniform distribution; Between handling support (2) and clamping band (4), three turnbuckles (3) are installed, are connected respectively the lower hanger (8) of handling support (2), the hanger (7) of clamping band (4).
2. crank journal claimed in claim 1 assembles overhead hoist, it is characterized in that: the lower hanger (8) of upper hanger (9) of handling support (2), (4) three hangers of clamping band, three turnbuckles (3), and be all equilateral triangle and distribute, three position is corresponding.
