Domain.
Background technique
Stake formula offshore platform is made of cushion cap (Texas deck) and pile foundation, and under marine environment, platform surface is easy life
Rust, needs periodically to carry out derusting anti-corrosive work.Currently, staff needs to set up big when carrying out platform lower surface derusting anti-corrosive
Foot-measuring hand cradle.Sea is set up scaffold and is carried out referring to land specification, generally using I-steel is laid with below platform, sets up full hall foot
The mode of hand cradle；It is larger to set up difficulty, when encountering severe sea condition, scaffold is often damaged by sea beat.No matter work people
Member on the operating platform with scaffold building when working, or in down operation platform, all inflexible convenience of taking action, and
And there are certain risk.Up to the present, there are no the high-efficient homework methods for solving platform lower surface derusting anti-corrosive.
Summary of the invention
Technical assignment of the invention is to solve the deficiencies in the prior art, provides a kind of derusting side of offshore platform lower surface
Method.
The present invention solves technical solution used by its problem above:
1. the design of lifting device
Lifting device uses crank arm type hydraulic lifting (as shown in Figure 1), which is power, from supporting leg, rises certainly
Drop is walked certainly, 360 ° of rotary operations.This equipment have it is easy to operate, easy to use, work surface is big, and can especially overhang work
Industry, the characteristics of a wide range of multi-point lifting operation can be carried out.In order to adapt to working environment, increase stabilization when lifting device work
Property, lifting device chassis is widened, width extends close to crossbeam two sides；Four wheels are designed as groove type steel wheel, make it
Width just blocks in orbit, facilitates walking (as shown in Figure 4)；Two manipulators are respectively set before and after vehicle body, in manipulator
Hydraulic clamp is arranged in end, when operation fixed lifting device (as shown in Figure 2).
2. the selecting and placing of track
In order to guarantee to crank arm, lifting device drives safely in orbit, and track need to have enough intensity and hardness.Channel steel uses
Standardized structural carbon steel, section are groove type.According to the length of platform beams, the appropriate length of channel steel is chosen；According to
The parallel track of the width placement twice of two side wheel of lifting device, track end are fixed with four semicircle stirrups, track and steel
Between hoop, (as shown in Figure 3) is connected by screw bolts between stirrup and stirrup.
Generated beneficial effect is the present invention compared with prior art:
Currently, staff needs to set up a large amount of scaffolds when carrying out platform lower surface derusting anti-corrosive.Set up scaffold ginseng in sea
It standardizes and carries out according to land, generally using I-steel is laid with below platform, set up the mode of full hall scaffold；It is larger to set up difficulty,
When encountering severe sea condition, scaffold is often damaged by sea beat.No matter staff is flat with the operation of scaffold building
When working on platform, or in down operation platform, all inflexible convenience of taking action, and also there are certain risk.For
Current condition, the invention proposes a kind of derusting method, this method task difficulty coefficient is small, easy to operate flexible, has very high
Safety, be able to solve the big problem of offshore platform lower surface anti-corrosion difficulty；Save a large amount of human and material resources；It operates spirit
Convenient feature living, substantially reduces the working time.

Specific embodiment
A kind of derusting method for cranking arm lifting device at sea platform lower surface of the invention is made in conjunction with attached drawing following detailed
It describes in detail bright.
As shown in Fig. 3, twice groove steel rail groove is placed on downwards on round crossbeam, and the end of each track makes a call to four
Bolt hole is fixed track and crossbeam with stirrup.The size of stirrup is designed as semicircle according to the size design of crossbeam, stirrup,
Inside there is rubber pad, to increasing friction force, stirrup both ends are equipped with bolt hole, and upper end is connect by bolt with track, and lower end passes through
Bolt is connect with another stirrup.Two semicircle stirrups cover on crossbeam, and there are gap, stirrup lower end uses bolt phase
Even, during tightening bolt, cover two semicircle stirrups tightly on crossbeam, track is fixedly secured to crossbeam
On, it ensure that lifting device of cranking arm drives safely in orbit.
As shown in Fig. 4, according to channel cross-section size design steel wheel groove, being allowed to just card, in orbit, steel wheel can be with
In orbit without the rolling of deflection.Lifting device of cranking arm is travelled in orbit by diesel engine powers, driving steel wheel, twice
Parallel orbit runs through entire platform, therefore cranks arm lifting device in driving range, can complete to remove entire platform surface
Become rusty corrosion prevention operation.In order to improve the stability for lifting device of cranking arm, equipment chassis is designed very wide, and guarantee is cranked arm in maximum radius
When operation, equipment is avoided to roll, guarantees the safety of personnel.
As shown in Fig. 2, it when lifting device of cranking arm somewhere carries out operation, needs to come to a complete stop equipment, and fixed, to guarantee
It works normally.In order to crank arm, lifting device is fixed, and the manipulator before and after vehicle body is arranged in and is put under the action of hydraulic stem
Under, when the contact track of end, the clamping device of opening starts to shrink under the action of hydraulic stem, controls the pressure of hydraulic stem
Manipulator is tightly embraced track by power, and equipment is fixed under the action of manipulator at this time.
As shown in Fig. 1, the lifting device of cranking arm after fixed starts operation, and when original state, hanging basket level is parked in bottom
Disk upper surface, staff enter hanging basket from chassis upper surface, various switching knobs are provided in hanging basket；When working condition, work
Make personnel and manipulate switching knob, can control hydraulic stem flexible, make to crank arm and raise or reduce.When platform rises to certain altitude,
Staff can be by manipulating switching knob, control turntable rotation, the operation of the achievable certain area of staff.It is every to complete one
After the operation in block region, lifting device of cranking arm restores to original state, and hydraulic stem withdraws manipulator, and Diesel Driven steel wheel is forward
Or travel backward, continue the operation of subsequent region.
