Block, electric panel room and arm support luffing mechanism module, afterwards big beam module, pylon module, rear support stand module, batter post support and front
Support module, hopper module, running mechanism module, and be hoisted on barge, above-mentioned modular transportation to harbour has been carried out by barge
Whole disassembling operation.Concrete work flow is as follows:
Refering to transport vehicle module of shown in Fig. 2, grabbing bucket, removed using suspension centre in the case of having suspension centre;In the case of there is no suspension centre,
Place steel cable sliding after setting backstop at the wheel of grab bucket transport vehicle, remove in the form of overall pocket hangs.
Refering to shown in Fig. 3, when front big beam module is removed, the main hook of crane barge and auxiliary hook are respectively acting on front crossbeam two ends, and main hook is made
For front crossbeam front end, front crossbeam front end is made to lift about 10 °, the brace of cutting front side, front tension bar is placed on front crossbeam;
Auxiliary hook raising treats power 100%, the articulated position of crossbeam before then cutting, and front crossbeam is first cut with scissors by operating personnel's operation on rear crossbeam
Connect cutting outside position to finish, then according to mode from bottom to top is cut, front crossbeam articulated position is internal (to be needed before cutting off in releasing
The connection members such as portion's cable).Cutting finishes, and after personnel withdraw, using crane barge, front crossbeam is hoisted on barge, lifts by crane process
In need to hang the cooperation of 4 cable ropes and fall to refuting, keep removing balance during handling for the part.Hang when tearing front crossbeam open, before avoiding
During pull bar lowering, other equipment is impacted, lowering velocity should be controlled.
Refering to shown in Fig. 4, before removing electric hoist truss module, first electric hoist is fixed with electric hoist truss welding, then cut off
Truss and the link position of pylon and luffing mechanism module, using crane barge, electric hoist and electric hoist truss are hoisted on barge.
Refering to shown in Fig. 5, remove electric panel room and arm support luffing mechanism module:First by elevator movement to bottom, disconnect elevator interim
Power supply.Because electric panel room is more with ship machine body connector, must confirm to cut off completely, by electric panel room and arm support luffing mechanism with
After ship machine body junction (including column, elevator well frame, stair etc.) is respectively cut, one is lifted to barge.
Refering to shown in Fig. 6, first hang the brace tearing top tower and both sides open, elevator well frame more than big top surface of the beam after then removing.
After dismounting during crossbeam, after rear crossbeam is removed, hopper module is cut off with crossbeam cylinder lever connecting rod, for guaranteeing that hopper will not tumble,
It is supported reinforcing with H profile steel below hopper;After crossbeam after simultaneously removing, rear support stand top is also connectionless, for preventing from inclining
Turn over, rear support stand is supported with batter post and is reinforced with fastener for connection;
Tear open after remaining elevator well frame refering to, shown in Fig. 7, hanging, when removing rear support stand module, using crane barge main hook by rear support
The door lower limb of frame lifts, and makes steel wire tensioning, is then separated land side doorframe body with running mechanism using gas cutting, finally utilizes pair
Hook is hoisted on barge after standing up rear support stand.
During refering to shown in Fig. 8, removing batter post support and front support stand module, the main hook of crane barge, auxiliary hook tangle batter post respectively and support
And the door lower limb of front support stand, the connection of the coupling part Qianmen Tui Yuhai side walking mechanism of cutting batter post support and land side walking mechanism
Part, is finally hung to barge using by batter post support and front support stand module.For preventing running mechanism after the dismounting of back and front supporting frame
Tumble, need to support reinforcing.
Refering to shown in Fig. 9, excision hopper is reinforced after supporting, and when removing hopper module, main hook and auxiliary hook pocket using crane barge hang
Hopper module, cuts off hopper and reinforces support and connector, after separating, hopper is hoisted on barge.
Refering to shown in Figure 10, excision wheel group is reinforced after supporting, and when removing running mechanism module, first removes rail clamping device, Ran Houli
With crane barge Xian Hai side hinterland side, running mechanism is hoisted on barge.
After crane barge is left the theatre, remove band conveyer corridor protection canopy.
Based on ship unloaders dismounting, ship loader does not have machine interior hopper part to the present embodiment, and other are identical with ship unloaders,
In sum, the present invention is directed to the body construction of dress ship unloaders, sequentially removes grab bucket transport using modular demolition technique
Car module, front big beam module, electric hoist truss module, electric panel room and arm support luffing mechanism module, afterwards big beam module, pylon mould
Block, rear support stand module, batter post support and front support stand module, hopper module, running mechanism module, can be at short notice
Complete loading, unloading ship machine projects, and complete for more time-consuming equipment disintegration is carried out in harbour offline area, thus reduce stopping
The machine time.So that the time taking dock operation is reduced to the shortest, saving material resources, manpower, improve work efficiency.So, this
Invention effectively overcomes various shortcoming of the prior art and has high industrial utilization.
Above-described embodiment only principle of the illustrative present invention and its effect, not for the restriction present invention.Any it is familiar with this skill
The personage of art all can carry out modifications and changes without prejudice under the spirit and the scope of the present invention to above-described embodiment.Therefore, such as
Those of ordinary skill in the art completed under without departing from disclosed spirit and technological thought all etc.
Effect modifications and changes, must be covered by the claim of the present invention.
