Description
Technical field
This utility model relates to a kind of locking and fixing device, is specifically related to a kind of for self-elevating drilling platform cantilever beam bow
Locking device is fixed in portion.
Background technology
Self-elevating drilling platform is during whole service life, and cantilever beam often to stretch out and reclaim, and such as platform exists
During towing condition, cantilever beam needs recovery to be locked；Fixed form and fixed effect by directly concerning whole cantilever beam are
Safety to full ship.Therefore the security reliability of locking device and can conveniently operate aobvious particularly important.
Utility model content
The purpose of this utility model is to provide a kind of cantilever beam bow locking device.
The technical solution adopted in the utility model is:
Cantilever beam bow locking device, including emergency generator deck house structure, locking latch, joining shackle, pulls calabash
Reed, described locking latch top is connected with lifting eye plate, lower end joining shackle in turn, and lower end joining shackle leads to by running through perforate
The steel wire rope of road sleeve pipe is connected with chain block, and described chain block is fixed on outstanding by upper end joining shackle with fixing hanger
Arm beam locking mechanism top, described cantilever beam locking mechanism is provided with fixation hook.
The internal diameter of described perforation channels sleeve pipe is more than the external diameter of deflation latch, and described deflation latch bottom is inside along girth
Cut tiltedly.
Advantage of the present utility model: locking and fixing device simple in construction, easy to operate, safety is high, shortens cantilever beam
The operating time being locked, improve work efficiency.
Accompanying drawing explanation
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is this utility model locking device schematic diagram when being locked；
Fig. 2 is this utility model locking device schematic diagram when unclamping.
Wherein: 1, cantilever beam structure；2, emergency generator deck house structure；3, cantilever beam locking mechanism；4, locking latch；
5, perforation channels sleeve pipe；6, eye plate is promoted；7, lower end joining shackle；8, steel wire rope；9, chain block；10, upper end joining shackle；
11, fixing hanger；12, fixation hook.
Detailed description of the invention
As shown in Figure 1-2, cantilever beam bow locking device, including emergency generator deck house structure 2, locking latch 4, connect
Unloading button, chain block 9, locking latch 4 top is connected with lifting eye plate 6, lower end joining shackle 7, lower end joining shackle 7 in turn
Be connected with chain block 9 by running through the steel wire rope 8 of perforation channels sleeve pipe 5, chain block 9 by upper end joining shackle 10 with
Fixing hanger 11 is fixed on cantilever beam locking mechanism 3 top, and cantilever beam locking mechanism 3 is provided with fixation hook 12, perforation channels sleeve pipe 5
Internal diameter more than tighten latch 4 external diameter, tighten latch 4 bottom inwardly cut along girth tiltedly.
When lifting operation, personnel can stand on the operating platform of outside, pulls bottle gouard moved by hands 9 can draw high locking latch
4, when the lifting eye plate 6 on locking latch 4 exposes perforation channels sleeve pipe 5, i.e. show that lifting puts in place, when needs are locked behaviour
When making, human users's bottle gouard moved by hands 9, locking latch 4 will move downward along perforation channels sleeve pipe 5 by self gravitation effect, insert
Entering the pin hole of cantilever beam structure 1, find when steel wire rope 8 loosens, i.e. show that emergent insertion puts in place, additionally personnel can also pass through
Marking time and shaking hands to enter device space of platform side is observed and is keeped in repair.
This utility model locking and fixing device simple in construction, easy to operate, safety is high, shortens cantilever beam and is locked
Operating time, improve work efficiency.
