Embodiment
More fully example embodiment is described referring now to accompanying drawing.But example embodiment can be implemented in a variety of forms, and should not be understood to be limited to embodiment set forth herein; On the contrary, provide these embodiments to make the present invention more comprehensively with complete, and the design of example embodiment is conveyed to those skilled in the art all sidedly.In the drawings, in order to clear, may be exaggerated the thickness of region and layer.Reference numeral identical in the drawings represents same or similar structure, thus will omit their detailed description.
In addition, described feature, structure or characteristic can be combined in one or more embodiment in any suitable manner.In the following description, provide many details thus provide fully understanding embodiments of the invention.But, one of skill in the art will appreciate that and can put into practice technical scheme of the present invention and not have in described specific detail one or more, or other method, constituent element, material etc. can be adopted.In other cases, known features, material or operation is not shown specifically or describes to avoid fuzzy major technique intention of the present invention.
The invention provides a kind of lid of taking off of leading smoke pipe and confirm device, for confirming whether the manhole cover of leading smoke pipe is uncovered by the cover-taking off device of leading smoke pipe.
Shown in Fig. 2, the lid of taking off of leading smoke pipe confirms that device is fixedly mounted on and is positioned at leading on smoke pipe 1 on water sealed tank 3.The lid of taking off of leading smoke pipe confirms that device comprises jacking part 10, support 20, driving section 30, trigger unit 40.Jacking part 10 can be a push rod, and its one end is stretched into and led in smoke pipe 1, and the other end exposes to leads smoke pipe 1, and can to lead in smoke pipe 1 mobile.Support 20 is fixed on leads on smoke pipe 1.Driving section 30 and trigger unit 40 are arranged at support 20, and the other end in jacking part 10, namely in Fig. 1 upper end effect under, driving section 30 can be rotated around support 20, to trigger trigger unit 40.Therefore, after manhole cover 3 is mentioned by cover-taking off device 4, jacking part 10 is by manhole cover 3 jack-up, in jack-up process, the promotion driving section, upper end 30 of jacking part 10, makes it rotate and triggers trigger unit 40, trigger unit 40 sends signal to the electrical control system of smoke guiding bogie, confirms that described manhole cover 3 is successfully uncovered.Thereby, it is possible to confirm whether manhole cover is uncovered accurately, avoid taking off lid erroneous judgement, cause wholely leading cigarette procedure failure, cause a large amount of raw gas to reveal, contaminate environment, and initiation security incident.
In the present embodiment, one end of leading smoke pipe 1 of stretching into of jacking part 10 has weight 11, to increase the weight of this end of jacking part 10, so that jacking part 10 free-falling.The middle part of jacking part 10 to have from its periphery stop section 12 outwardly, the non-uncovered state of the manhole cover of leading smoke pipe shown in Fig. 1, jacking part 10 is stretched into and is led in smoke pipe 1, and open height lower than the default of manhole cover, stop section 12 is by block in leading outside smoke pipe 1, and what can limit jacking part 10 stretches into the distance leading smoke pipe 1.The upper end also projection jacking block 13 of jacking part 10, in order to contact with driving section 30, and promotes driving section 30 and rotates.
In the present embodiment, driving section 30 comprises fork 31, coupling shaft 32 and lance 33.Contiguous jacking part 10, one end of fork 31, and can be provided with touching part 311, in order to by jacking block 13 ejection.As shown in Figure 3, the middle part of coupling shaft 32 is hubbed at support 20, and one end of coupling shaft 32 is fixedly connected with the other end of fork 31, and the other end of coupling shaft 32 is fixedly connected with one end of lance 33.
Certainly, the structure of driving section is not limited thereto, and can increase according to practical situation or reduce parts.
In the present embodiment, trigger unit 40 is collision type limit switch, its Rocker arm 42 having body 41 and can rotate around body 41.Under non-trigger state, Rocker arm 42 is horizontal, and the other end of lance 33 is erected on Rocker arm 42.After manhole cover 3 is raised, jacking part 10 is pushed up by manhole cover 3, fork 31 is driven to be rotated counterclockwise, simultaneously, the coupling shaft 32 be fixedly connected with fork 31 is rotated counterclockwise, press down Rocker arm 42 while lance 33 is rotated counterclockwise, make trigger unit 40 send signal to the electrical control system of smoke guiding bogie, confirm that described manhole cover 3 is successfully uncovered.
Trigger unit 40 is also proximity switch, and along with lance 33 is rotated counterclockwise, the distance of itself and trigger unit 40 reduces, thus triggers trigger unit 40 and send signal to the electrical control system of smoke guiding bogie.
Therefore, the form of trigger unit 40 is not limited thereto, and anyly can the existing triggering mechanism sending signal be coordinated all to be included in protection scope of the present invention with driving section 30.
The lid of taking off of leading smoke pipe confirms that device also can comprise resetting mechanism 50, and in the present embodiment, resetting mechanism 50 is spring.The middle part of coupling shaft 32 sets firmly arm-tie 321.Support 20 is fixed in one end of resetting mechanism 50, and the other end is fixed on arm-tie 321.
When the manhole cover of leading smoke pipe is not opened, spring is preferably in compressed state or free state.When manhole cover is lifted, along with spindle 32 is rotated counterclockwise, the corresponding rotation of arm-tie 321, spring is stretched, as shown in Figure 2.Lead after cigarette process completes, uncovery mechanism 2 makes manhole cover 3 fall, and jacking part 10 drops to starting position by deadweight, and spring-return is to original state, and drive lance 33, coupling shaft 32 and fork 31 to reset, whole cover buckle lid process of taking off completes.
In sum, lid of taking off of leading smoke pipe of the present invention confirms that device can confirm whether manhole cover is uncovered accurately, avoids taking off lid erroneous judgement, causes wholely leading cigarette procedure failure, causes a large amount of raw gas to reveal, contaminate environment, and initiation security incident.And the lid of taking off of leading smoke pipe confirms the simple to operate, rational in infrastructure of device.
Although exemplary embodiment describe the present invention with reference to several, should be appreciated that term used illustrates and exemplary and nonrestrictive term.Spirit or the essence of invention is not departed from because the present invention can specifically implement in a variety of forms, so be to be understood that, above-described embodiment is not limited to any aforesaid details, and explain widely in the spirit and scope that should limit in claim of enclosing, therefore fall into whole change in claim or its equivalent scope and remodeling and all should be claim of enclosing and contained.
