Fig. 2-Fig. 3 is the flow signal in the utility model large diameter borehole casing sinking construction tool adjustment adaptation aperture
Figure.
Specific implementation mode
With reference to embodiment and its attached drawing, the utility model is described in further detail, and following embodiment is descriptive
, it is not restrictive, protection scope of this utility model cannot be limited by this.
As depicted in figs. 1 and 2, Fig. 1 shows a kind of large diameter borehole casing sinking construction tool, including puts relatively two-by-two
Four hoist engines 1 set, each hoist engine 1 all have pedestal 2, are provided on pedestal 2 and are mutually leaned on for hoist engine 1 staggered relatively
Close or remote from sliding rail；Rack and pinion drive mechanism is installed on pedestal 2, the rack and pinion drive mechanism includes centre tooth
Wheel 3 and two toothed racks 4 that engage of 3 both sides of central gear, two toothed racks 4 respectively with 4 phase of a toothed rack of the hoist engine of both sides 1
Mutually intersect and is connected by axis pin 5；Hoist engine 1 staggered relatively is driven by rack and pinion drive mechanism and is mutually leaned on sliding rail
Close or remote from.
The central gear 3 drives its rotation by motor 6.
The hoist engine 1 passes through its rotation of synchronous machine drives.
The synchronous motor passes through Digiplex remote control.
Motor 6 on hoist engine 1 staggered relatively, which synchronizes, to be rotate in same direction, and corresponding two 1 rack-and-pinion of opposite hoist engine pass
Motivation structure synchronizes homodromous rack 4 and is connect with the rack 4 on the same side hoist engine 1.
The button 8 that control motor 6 starts and stops is provided on pedestal 2.
The button 8 is including rotating clockwise startup, stop button 8 and rotating counterclockwise startup, stop button 8.
The course of work of this large diameter borehole casing sinking construction tool：
Manual control steel wire rope is changed to hoist engine 1 to control, 1 cylinder stent of hoist engine of welding is changed to four groups can be towards brill
Hole is close or the guide rail of principle, mate gear rack gear keep the space size in four hoist engines 1 adjustable.
The first step：Two staff coordinate the motor 6 for starting two hoist engines 1 staggered relatively (in order to further
Synchronous, the motor 6 of two hoist engines 1 staggered relatively passes through 8 synchronous control of a set of button), so that central gear 3 is rotated, center
Gear 3 drives two racks 4 to be retracted into pedestal 2 or stretched out to outside pedestal 2 simultaneously；The hoist engine 1 of opposite side carries out together simultaneously
Step acts, two-by-two the spacing between two opposite hoist engine 1 of cooperation adjustment residue.
It is illustrated in figure 2 the contraction for coordinating distance between guide rail realization both sides hoist engine 1 by rack and pinion drive mechanism,
The profile that four groups of hoist engines 1 surround at this time becomes rectangle from original square.
Second step：Two staff coordinate the motor 6 for starting other two hoist engine 1 staggered relatively, make central gear 3
Rotation, central gear 3 drive two racks 4 to be retracted into pedestal 2 or stretched out to outside pedestal 2 simultaneously；The elevator of opposite side simultaneously
Machine 1 synchronizes action, two-by-two the spacing between other two opposite hoist engine 1 of cooperation adjustment.
It is illustrated in figure 3 the contraction for coordinating distance between guide rail realization both sides hoist engine 1 by rack and pinion drive mechanism,
The rectangular change of rectangle of profile that four groups of hoist engines 1 surround as shown in Figure 2 is set to be square.
Since the position of guide rail is in 2 part of pedestal of hoist engine 1, and distance of stretch out and draw back is identical always, therefore is stretching
1 fuselage of hoist engine is always at the midpoint of rectangle four edges in journey, to ensure that four hoist engines 1 form square, to adapt to not
Sink with diameter casing, and in four hoist engines 1 be synchronous motor, is controlled by a Digiplex, can guarantee suspention in this way
The cement casing 7 steadily declines, and engineering construction finishes, can extract axis pin 5, shrinks guide rail and reduces space, facilitates transfer.
The preferable specific implementation mode of the above, only the utility model, but the scope of protection of the utility model is not
It is confined to this, any one skilled in the art within the technical scope disclosed by the utility model, can readily occur in
Change or replacement, should be covered within the scope of the utility model.Therefore, the scope of protection of the utility model should
Subject to the scope of protection of the claims.
