Technical field
The utility model is related to geology drilling engineering field more particularly to a kind of large diameter borehole casing sinking construction works Tool.
Background technology
Currently, major diameter vertical shaft sinking cement casing construction method is mostly by lowermost end cement tube sealed bottom, and the bottom of at Four lifting lugs of end setting, steel wire rope lock after winding three circles on cylinder stent on lifting lug, and construction personnel works in coordination, and leads to Crossing elastic steel wire rope makes cement casing sink or suspend to.Since cement casing is mostly merogenesis manufacture, field joint and sealing, Lead to not sink as casing quantity increases its suffered buoyancy, at this moment need under casing adds water or mud that casing is forced to continue Heavy, construction personnel needs to haul beside vertical shaft always under steel wire rope prevents cement casing from sinking or is uneven in whole process It is heavy, huge to construction personnel's muscle power and energy consumption and dangerous higher during Butt sealing cement casing.
Utility model content
Disadvantage in for the above-mentioned prior art and deficiency, the purpose of this utility model is to provide a kind of the degree of automation The large diameter borehole casing sinking construction tool that height can adapt to multiple aperture drilling, reduce manpower output and danger coefficient.
The purpose of this utility model is achieved through the following technical solutions:
A kind of large diameter borehole casing sinking construction tool, including four hoist engines staggered relatively two-by-two, each elevator Machine all has pedestal, is provided on pedestal for hoist engine staggered relatively sliding rail close to each other or separate;It is installed on pedestal There is a rack and pinion drive mechanism, the rack and pinion drive mechanism includes central gear and central gear both sides engage two Toothed rack, two toothed racks respectively intersect with a toothed rack of the hoist engine of both sides and are connect by axis pin;Volume staggered relatively It is close to each other or separate on sliding rail by rack and pinion drive mechanism driving to raise machine.
Preferably, the central gear drives its rotation by motor.
Preferably, the hoist engine passes through its rotation of synchronous machine drives.
Preferably, the synchronous motor passes through Digiplex remote control.
Preferably, the motor synchronous on hoist engine staggered relatively rotates in same direction, corresponding two opposite winding gear teeth Strip transmission mechanism synchronizes homodromous rack and is connect with the rack on the hoist engine of the same side.
Preferably, the button of control motor starting and stopping is provided on pedestal.
Preferably, the button is including rotating clockwise startup, stop button and rotating counterclockwise startup, stop button.
Preferably, the motor of two hoist engines staggered relatively passes through a set of button synchronous control.
Compared with prior art, the embodiment of the utility model large diameter borehole casing sinking construction tool at least have with Lower advantage:
(1) it is suitble to multiple caliber;
(2) it is moved by guide rail quick and easy;
(3) detachably, facilitate transfer;
(3) casing tilt phenomenon caused by manual operation mismate is reduced;
(4) operating personnel are few, save muscle power and energy, safety.
Description of the drawings
Fig. 1 is the hoist engine structural schematic diagram of the utility model large diameter borehole casing sinking construction tool;
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.
