Description
Technical field
The utility model relates to a kind of top or lifts class lifting Work tool, especially relates to a kind of used in nuclear power station Simple jack device.
Background technology
Jack is mechanical equipment installation, dismounting, adjustment time the one that uses commonly use Work tool, the mechanical type that current Work tool manufacturer provides and split hydraulic jack exist volume more greatly, comparatively heavy, the deficiencies such as inapplicable narrow space operation, moreover nuclear power plant equipment is various, a lot of equipment installation, maintenance narrow space, required jack class lifting Work tool pattern is various, and the finished product jack of buying cannot meet the demand of equipment component when installation, maintenance.
Utility model content
The purpose of this utility model is exactly provide to overcome defect that above-mentioned prior art exists that a kind of range of use is wide, safe and reliable, maintenance is convenient, the used in nuclear power station Simple jack device of cost saving.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of used in nuclear power station Simple jack device, it is characterized in that, comprise nut base, spiral ejection pin and the spherical decorative pearl on top of an official cap, described spiral ejection pin one end is connected with nut base by thread, and the other end is provided with the ball recess for placing the spherical decorative pearl on top of an official cap.
Preferably, described spiral ejection pin is provided with outside thread, and described nut base is provided with the negative thread corresponding with spiral ejection pin outside thread.
Preferably, described outside thread and negative thread are Acme thread.
Preferably, described ball recess is located at the center of spiral ejection pin end face.
Preferably, the sphere center position of the described spherical decorative pearl on top of an official cap is positioned at inside grooves.
Preferably, the vertical distance between described sphere center position and spiral ejection pin end face is 0.3 to 0.7mm.
Preferably, described vertical distance is 0.5mm.
Preferably, gap is provided with between described ball recess and the spherical decorative pearl on top of an official cap.
Preferably, lubricant is filled with in described gap.
Preferably, the described spherical decorative pearl on top of an official cap is bearing ball.
Compared with prior art, the utility model has the following advantages:
1, range of use is wide: can be used for the top of equipment, lift adjustment, the dismounting of bearing, shaft sleeve parts, the installation, maintenance area of activities such as the expansion of pipeline, valve flanges, are particularly useful for the jobs such as the measurement of steam turbine thrust bearing shoe valve thrust clearance, bear box oil seal washer location.
2, safe and reliable: to adopt the machinework of #45 steel to make, modulation treatment, and different size can be processed into meet on site maintenance space and requirement of strength.The Acme thread of medium accuracy has auto-lock function, there will not be slippage, certainly falls situation.
3, maintenance is convenient: the little maintenance environment being applicable to multiple narrow space of volume, easy to carry.
4, cost saving: material requested is cheap, processing technology is simple, reusable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment
As shown in Figure 1, a kind of used in nuclear power station Simple jack device, comprises nut base 1, spiral ejection pin 2 and the spherical decorative pearl on top of an official cap 3, and described spiral ejection pin 2 one end and nut base 1 are threaded connection, and the other end is provided with the ball recess for placing the spherical decorative pearl on top of an official cap 3.
Described spiral ejection pin 2 is provided with outside thread, and described nut base 1 is provided with the negative thread corresponding with spiral ejection pin outside thread.Described outside thread and negative thread are Acme thread.
Described ball recess is located at the center of spiral ejection pin 2 end face.The sphere center position of the described spherical decorative pearl on top of an official cap 3 is positioned at inside grooves.Vertical distance between described sphere center position and spiral ejection pin 2 end face is 0.5mm.
Gap is provided with between described ball recess and the spherical decorative pearl on top of an official cap 3.Lubricant is filled with in described gap.The described spherical decorative pearl on top of an official cap 3 is bearing ball.
Nut base 1 and spiral ejection pin 2 are processed with the trapezoidal internal and external screw thread of Tr30 × 3, and precision and tolerance adopt medium accuracy tolerance 7H and 7e, by realizing pushing and auto-lock function with six on S46 open-end spanner rotating screw push rod.A ball recess is machined in addition at the head of spiral ejection pin, inlay a spherical ball 3, select slidably free-running fit (F8/h7) therebetween, and add lubricant, by the slip of ball when spiral ejection pin rotates, the friction force of push rod and jacked object part greatly can be reduced.According to on-site actual situations needs, adjustable Acme thread nominal diameter and screwing length L1, L2.
Described nut base 1 is placed on (as positions such as platen, casing, flange, spindle nose end faces) on fixed support plate corresponding to jacked object part, spiral ejection pin 2 withstands on the suitable position of jacked object part by the spherical decorative pearl on top of an official cap 3, rotate spiral ejection pin with spanner and just can realize the function pushing object, and by installing the requirement that measuring instrument is easy to realize controlling to push distance additional.
As steam turbine thrust bearing shoe valve thrust clearance is measured.Due to low pressure rotor heavily about 200 tons, between overhaul time, do not having under apical axis oil condition, push-jump son is more difficult, so select to push away with described Simple jack the measurement object that watt shell can reach same, operates fairly simple, time saving and energy saving.Two described Simple jack symmetries are placed into the thrust bearing shoe valve shell left and right sides by method of operation: set up dial measuring gauge on rotor and thrust bearing shoe valve shell, push away to tune end simultaneously; Jack is placed into tune end position, can push away to electricity end.
