Description

Center steering lose-lose oil pipe folding-jib oil transfer arm hoisting crane

Technical field

The utility model relates to the folding-jib oil transfer arm hoisting crane of installing on the boats and ships such as oil tanker, chemical carrier, is specifically related to a kind of center steering lose-lose oil pipe folding-jib oil transfer arm hoisting crane.

Background technology

At present, oil tanker and chemical carrier matching used oil transfer arm hoisting crane has only the straight-arm pattern, does not still have the folding arm pattern.The keystone configuration pattern that is used for transport pipe folding-jib oil transfer arm hoisting crane on the boats and ships has two kinds: a kind of be directly on the jib of flexible pipe hoisting crane or arm inside lay single tube or two-tube oil pipeline, pipe ends weld ell and flange directly link to each other with flexible pipe again.Another kind is on crane arm support or single tube or two-tube oil pipeline are laid in inside, jib rotate root and with the concentric SAH of loading onto of turning cylinder.The shortcoming of first kind of pattern is: when arm luffing or revolution, oil hose is and then swing all.The shortcoming of second kind of pattern is: though flexible pipe is not swung during the arm luffing, and also and then swing during revolution.More than two kinds of patterns also exist maximum shortcoming simultaneously and be: need bigger flexible pipe swing space around the hoisting crane column; The bigger between deck space that so not only accounts for, and dangerous, also need manual work to make flexible pipe in order besides; And with the cabin hydraulic fluid port to after connecting; Can begin oil transportation, crewman's work capacity is bigger, can't satisfy the requirement of sharp work.To take the deck on the ship space also bigger, particularly outstanding to the boats and ships of deck difficult arrangement especially for arm in addition.

Summary of the invention

In order to overcome above-mentioned shortcoming; The purpose of the utility model provides a kind of center steering lose-lose oil pipe folding-jib oil transfer arm hoisting crane; Can realize that two kinds of different medium liquid of each other isolating are carried to another ship or harbour oil depot by lash ship simultaneously, can realize the usefulness of all kinds of boats and ships lifting foreign material, food, spare part and other article again.

The technical solution of the utility model is: this hoisting crane comprises deck stand, revolution pedestal, amplitude oil cylinder, the winch that hoists, basic arm, folding arm oil cylinder and folding arm; Deck stand is installed on the lash ship deck, on deck stand, through pivoting support the revolution pedestal is installed, and in revolution pedestal upper end basic arm is installed; Connect folding arm through twisted axis on the arm of basis; The winch that hoists is installed in arm below, basis, and amplitude oil cylinder is installed on revolution pedestal and the basic arm, and the folding arm oil cylinder is installed on basic arm and the folding arm; It is characterized in that: transport pipe is through pipe clamp be laid in basic arm and folding arm both sides; Making transport pipe on the folding arm follow folding arm through a swivel coupling with two arm twisted axis concentrics rotates; In the pitch rotation of basic arm, turn round base interior through two transport pipe being introduced in the heart with No. two swivel couplings of twisted axis bonded assembly; The two-tube swivel coupling in central mounting center at the revolution pedestal; Two transport pipe in the revolution pedestal from dynamically being incorporated in the crane deck pedestal, are received pipeline around the property joint interface of corresponding cabin fuel transfer pump again through gyro-rotor warp separately.

Wherein, guardrail and manoeuvring platform are installed, slewing limiter are installed in revolution pedestal lower end in revolution pedestal upper end.

Wherein, on basic arm and folding arm, aerial ladder is installed.

The utlity model has following advantage:

1, the arm of hoisting crane is two joint case structures; Be divided into basic arm and folding arm, through the folding arm oil cylinder two arms folded, transport pipe is through the be laid in both sides of arm of pipe clamp; Transport pipe on the arm is folding with the arm body on the one hand; Make transport pipe on the folding arm follow folding arm through swivel coupling on the other hand and rotate, on ship deck, can keep optimum balance like this, dwindled taking up room of deck again with two arm twisted axis concentrics;

2, two transport pipe can be carried two kinds of identical or different liquid dielectrics simultaneously, and lash ship does not have the flexible pipe swing when work;

3, make two-tube swivel coupling in center and being connected of deck stand floating type; Transport pipe is directly received ship oil pump discharge place with the hard steel pipe with pipeline through the two-tube swivel coupling in the center of hoisting crane body; So both reduced crewman's labour intensity; Safer during work, satisfy the requirement of sharp work again.
