Specific embodiment
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings：
See Fig. 2, be the utility model closure door self-locking coaster example structure schematic diagram, the body 8 including integral structure,
Traveling pulley 9 transfers pulley 10 and closure door 11, and 8 top of body is downwardly open groove body, and traveling pulley 9, row are equipped in groove body
It is connected into pulley 9 by wheel shaft 1 with body 8, a side of groove body is free-end 12, and free-end 12 is equipped with messenger
Messenger 25 is thrown in hole 14, messenger hole 14 for connecting.
Free-end 12 is equipped with outside guiding arc 20, and guiding aerial condutor 28 when operating of conveniently reaching the standard grade enters slot.Body 8 pushes up
Portion is equipped with free bearing 16, and one end of operation panel 17 is hinged with free bearing 16, and the other end is equipped with earhole plate 18.One end of closure door 11 passes through
Axis pin 13 is hinged with body 8, and torsional spring 15 is equipped between axis pin 13 and closure door 11, when closure door is from external force, the torsion of torsional spring 15
The other end of closure door is made mutually to be taken with free-end, keeps closed state.
In embodiment, it is connected between closure door 11 and operation panel 17 by stretch nylon rope 19,19 one end of stretch nylon rope
Solid ring 1 in connection closure door 11, the solid ring 2 30 on other end attended operation plate 17, when operation panel 17 is rotated around free bearing 16
When, 11 overturning of closure door will be driven, releases closing.Body 8 is equipped with windowing 21, and stretch nylon rope 19 is by the guide wheel 22 in windowing 21
Base passes through, and guide wheel 22 is connected by guide shaft 31 with body 8.
The bottom of body 8 is fork pocket structure, is equipped in fork pockets and transfers pulley 4, transfers pulley 4 and passes through wheel shaft 2 27 and fork pockets
It is connected, transfers pulley 10 and be used for around transmission rope 24 is hung, the effect of transmission rope 24 is the tool for transmitting after coaster is reached the standard grade in place.
See Fig. 3, be that the utility model closure door self-locking coaster embodiment is reached the standard grade view, when preparing coaster being suspended to frame
When on hollow wire 28, it will first throw 25 one end of messenger and tie on free-end 12 that transmission rope 24 is winded at transmission after passing through earhole plate 18
On pulley 10, tail of rope end fastens to form becket bridle.The other end for throwing messenger 25 is bypassed into frame with the method for unmanned plane lifting or throwing
Hollow wire 28, ground staff drag the other end fag end of throwing messenger 25 with pulling, and until coaster is raised, body 8 is inclined at this time
State, operation panel 17 open naturally due to dead weight, and closure door 11 is in non-closed state by the traction of stretch nylon rope 19.With landing
Dough figurine person continues to pull, and free-end 12 and guiding 20 priority of arc slip over aerial condutor 28, and traveling pulley 9 falls on aerial condutor 28
On, stop pulling at this time, coaster recovers upright position by self gravitation, and operation panel 17 also recovers upright position, closure door by dead weight
11 lean on the effect of torsional spring to be restored to closed state, and operation of reaching the standard grade terminates.Ground staff can start to repair by operation transmission rope 24
Operation.
See Fig. 4, be the utility model closure door self-locking coaster embodiment down status schematic diagram, after maintenance activity,
Make a call to a knot 23 of unloading temporarily in transmission rope 24, ground staff pulls transmission rope 24 on ground, when 23 row of knot of unloading is to earhole
When on plate 18, continue to pull downward on transmission rope 24, operation panel 17 will be made to be rotated around free bearing 16, and then body 8 is driven to overturn, seal up a door
11 digging when affecting because operation panel 17 release closed state, continue to pull transmission rope 24, while control the rope for throwing messenger 25
End, until 28 priority of aerial condutor slips over guiding arc 20 and free-end 12 exits, completion is unloaded operation.Thereby realize operation
Personnel need not step on tower can ground complete transmission rope throwing hang work, this closure door self-locking structure, coaster reach the standard grade with it is offline
When can automatically open, and when carrying out transmission operation on line, closure door is then shut automatically, therefore it is hidden to have prevented the accident that coaster comes off
Suffer from, the labor intensity of mitigation, while improve job safety coefficient.
Above example is only the tool the purpose of this utility model to be described in detail, technical solution and advantageous effect are chosen
Body example, but should in no way limit the scope of protection of the utility model, it is all without prejudice to before the spirit and principles of the utility model
It puts, various modifications, equivalent substitution and the improvement made should all be fallen within the scope of protection of the utility model.
