Main frame uses PLC main control computers；
The thrustor includes a bottom plate, and bottom base plate has the sliding shoe being installed on slide rail, and sliding shoe is installed on
On slide rail, the upper end of bottom plate is provided with least two jacking cylinders, and the outboard end of bottom plate is provided with a support platform, the support
One passage oil cylinder is installed on platform, a sliding block is fixedly mounted on the piston rod of passage oil cylinder, sliding block loads in support platform
In the chute that upper end opens up, one block of bias correcting plate is installed in the side of the bottom plate by rotating shaft activity.
As preferable technical scheme, the oil circuit of the passage oil cylinder and jacking cylinder connects hydraulic pressure by oil pipe respectively
Pumping plant, it passes through the break-make of solenoid valve control oil circuit.
As preferable technical scheme, the medial surface of the bias correcting plate has a guiding for protruding from corrected board end face
Bar, is provided with helical guideway on the guide rod, and the helical guideway that one end of the sliding block is oppositely oriented bar sets a guide pad,
The guide pad is buckled into helical guideway.
As preferable technical scheme, the sliding block is moved to chute extreme position hour offset corrected board towards jacking cylinder
Move in direction.
The beneficial effects of the utility model are：The utility model is simple in construction, has subtracted the correction that deviation correction mechanism uses and has used
Oil cylinder, reduce the use of oil cylinder, and with the function of the automatic deviation correction in passage.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only

State, can alternative features equivalent by other or with similar purpose replaced.I.e., unless specifically stated otherwise, each feature
It is an example in a series of equivalent or similar characteristics.
As shown in figure 1, including slide rail 1, the multigroup thrustor being installed on slide rail 1, the thrustor passes through hydraulic pressure
Pumping plant drive control, control main frame use PLC main control computers；
Thrustor includes a bottom plate 11, and the bottom of bottom plate 11 has the sliding shoe being installed on slide rail, and sliding shoe is installed on
On slide rail, the upper end of bottom plate 11 is provided with least two jacking cylinders 12, and the outboard end of bottom plate 11 is provided with a support platform
13, a passage oil cylinder 8 is installed in the support platform 13, a sliding block 9, sliding block 9 are fixedly mounted on the piston rod of passage oil cylinder 8
It is fitted into the chute 5 that support platform upper end opens up, the side of bottom plate 11 passes through the activity one block of bias correcting plate 3 of installation of rotating shaft 2.
In the present embodiment, the oil circuit of passage oil cylinder 8 and jacking cylinder 12 connects hydraulic power unit by oil pipe respectively, and it is logical
Cross the break-make of solenoid valve control oil circuit.
The medial surface of bias correcting plate has a guide rod 6 for protruding from corrected board end face, and spiral is provided with guide rod 6
Guide rail 4, one end of sliding block 9 are oppositely oriented one guide pad 7 of setting of helical guideway 4 of bar, and the guide pad 7 is buckled into helical guideway
