Ear mount is connected after derrick；
Two derrick installations guiding are respectively arranged with towards derrick both sides in winch sled body of work platform, prizes and leads in winch
Body running platform is respectively arranged with a derrick lifting oil cylinder towards derrick both sides, and derrick lifting cylinder block base connects with oil cylinder
Lug seat is hinged, and oil cylinder connection ear mount is fixed on winch sled main body middle beam.
Support derrick of the present utility model is prized with Multifunctional winch, is further characterized in that：
Described winch sled main body has three-decker, and first layer is used for setting winch；The second layer be used for install air hoist,
Dead line anchor, rope rewind machine；Third layer is workbench, and hanging ladder is provided between the workbench and ground.
The three-decker of described winch sled main body is provided with bed board.
The beneficial effects of the utility model are can to play a part of conventional winch sunshade, can be used to install pneumatic again
The equipment such as winch or hydraulic wireline winch, while can play a part of derrick A-frame, supports derrick so that rig floor space of planes is released
Put, substantially increase drilling well operating efficiency, be embodied in：
1) can be drilling floor surface by part drill floor equipment integrated installation in winch is prized in the case where not influenceing its function
Save the confined space.
2) derrick A-frame can be replaced, for installing derrick, strengthens derrick installation stability；Installation is designed with simultaneously to be oriented to
Part, installation, raising and the decentralization of derrick when facilitating the platform to move；In assembly and disassembly operating mode and harsh ocean operating mode,
There is provided for the derrick that fell and safe and reliable anti-brush up against support.
3) protective action is served for winch and equipment component in severe marine environment, improves service life of equipment；
And winch is one of key equipment of marine drilling, it is necessary to often safeguard, winch sled provides for maintained equipment to be facilitated.
4) traditional winch sunshade, only serves the effect becalmed and taken shelter from rain for winch, occupies certain on drilling floor surface
Space so that the operating space of workman is reduced, occupies limited rig floor space of planes.Multifunctional winch sled has certain height
Degree, is to be designed to meet structure type that winch works under bad working environments, is not take up the operating space of drilling floor surface workman,
The drill-well operation of driller is not influenceed.

In figure, 1. winches sled main body, 2. winches, which are prized to connect before supporting leg, 3. derricks, connects ear mount, 5. wells after ear mount, 4. derricks
Oil-lifting jar is erected, 6. derrick installations are oriented to, 7. oil cylinders connection ear mount, 8. hanging ladders.
The utility model is described in detail with reference to the accompanying drawings and detailed description.
Reference picture 1, Fig. 2, Fig. 3, Fig. 4, structure of the present utility model is, including prizes main body 1 as the winch of architecture basics,
For demountable structure, winch sled main body 1 has three-decker, and first layer is used for setting winch；The second layer be used for install air hoist,
The equipment such as dead line anchor, rope rewind machine, save the operating space of drilling floor surface driller；Third layer is workbench, the work
Hanging ladder 8 is provided between platform and ground, is easy to above and below personnel；
Winch prizes the workbench of main body 1 and derrick is provided with a pair of cantilevers, the lug hinge of this pair of cantilever front underside
A winch sled supporting leg 2 is connected to, winch sled supporting leg 2, which is used to fix with rig floor steel structure base, to be hinged, this pair of cantilever front end upper table
Face, which is provided with before derrick connection ear mount 3 before connection ear mount 3, derrick, is used for corresponding with derrick point articulated, this pair of cantilever rear end upper table
Face, which is provided with after derrick connection ear mount 4 after connection ear mount 4, derrick, to be used for and derrick in addition corresponding point articulated；
Two derrick installations are respectively arranged with towards derrick both sides in the winch sled workbench of main body 1 and are oriented to 6, in winch sled
The workbench of main body 1 is respectively arranged with a derrick lifting oil cylinder 5 towards derrick both sides, the cylinder body base of derrick lifting oil cylinder 5 with
Oil cylinder connection ear mount 7 is hinged, and oil cylinder connection ear mount 7 is fixed on the winch sled middle beam of main body 1.
Derrick installation is oriented to 6 total of four, and derrick lifting oil cylinder 5 is provided with two altogether.
