Abstract
The utility model relates to an automatic manhole that opens and shuts of formula of turning over on for steel vessel, manhole simple structure is novel, through the control cylinder realize automatic open with lock, convenient operation. Parts are including welding in the manhole shell ring of container, the cylinder of being connected with the manhole cover of shell ring through hinge connection, through hinge and frame and manhole cover, controlling the pneumatic control valve that the cylinder moved. Characterized in that sets up a pair of earrings respectively in manhole cover and frame, the middle cylinder that passes through is connected, so constitute a pair swing guide -bar mechanism, with manual three -position four -way valve control cylinder, surround its hinge upset through the moving handhole door of cylinderpiston's slip band to the operation with the lock is opened from top to bottom to the realization manhole cover. Artifical physical power is saved to the similar manipulator of cylinder effect, manhole cover opening angle under the control of cylinder is controllable simultaneously, safe and reliable, the manhole cover upwards turns over and effectively utilizes the space, has avoided a great deal of intervene problem that traditional turning on one's side caused.
Description
Technical field
The utility model relates to a kind of upper-turn-type automatic open-close manhole for steel vessel, and manhole structure is simply novel, realizes automatically opening and fastening by control cylinder, easy to operate,
Background technology
In existing manhole, operationally there is following problem in most of manhole:
1. manhole cover rollover, often interferes with the parts such as visor, compression indicator of surrounding, takies operational space.
Even if 2. groups of people's port lid turns over form on adopting, but because the manhole cover after unlatching is without any constraint, especially under opening angle limited situation, manhole is stamped the safety hazard automatically fallen.
3. some pressure manhole covers are often very heavy, and some is painstaking in artificial folding.
4. manhole cover opening angle is uncontrollable, when some does not need full open, and elapsed time and manpower.
Utility model content
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of upper-turn-type automatic open-close, fast open type manhole safe and efficient, easy to use.
The purpose of this utility model is reached by following measure:
1. manhole shell section is welded on steel vessel upper cover appropriate location according to the form that manhole cover turns over.
2. manhole cover by hinge and manhole shell section hinged.On manhole cover, a pair earrings is welded in appropriate location, is used for cylinder piston boom end hinged.
3. in steel vessel frame, a cylinder block is fixed in appropriate location, is used for tail cylinder hinged.
4. cylinder A, B two admission ports connect a pneumatic speed control valve respectively, and speed control valve is connected with A, B mouth tracheae of manual three-position four-way valve respectively.Adopt the closed manual three-position four-way valve of meta, P mouth is connected with source of the gas by tracheae.
For the defect of existing manhole, the utility model has done corresponding innovative approach in design, and its advantage is:
1. manhole cover turns over, effectively utilize upper space, no longer occur interfering phenomenon with peripheral parts.
2. be subject to the constraint of cylinder, manhole cover does not have the safety hazard automatically fallen.
3., by control cylinder folding manhole cover, save manpower.
4. manhole cover opening angle controls by cylinder, handled easily.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Isometric view, wherein 1. manhole shell section 2. manhole cover 3. snap close 4. earrings 5. piston rod 6. cylinder 7. speed control valve 8. cylinder block 9. container frame 10. manual three-position four-way valve when Fig. 1 is manhole fastening
Detailed description of the invention
1., when manhole cover fastens, cylinder piston rod is in the state of stretching out, and meta put by manual three-position four-way valve.
2. cylinder A (afterbody), B (head) two admission ports connect a pneumatic speed control valve respectively, and speed control valve is connected with A, B mouth tracheae of manual three-position four-way valve respectively.Adopt the closed manual three-position four-way valve of meta, P mouth is connected with source of the gas by tracheae.
3. when needing to open manhole, first open each snap close of manhole, then pulling hand valve makes B mouth communicate and air inlet with P mouth, cylinder piston rod bounces back, manhole cover is opened around hinge hinge upset, and opening speed can as required by being connected to the speeds control valve regulation of B mouth, after being opened to proper angle, pull hand valve and put meta, manhole cover is fixed.
4. when needing to fasten manhole, pulling hand valve makes A mouth communicate and air inlet with P mouth, cylinder piston rod stretches out, manhole cover fastens around hinge hinge upset, and fastening speed can as required by being connected to the speeds control valve regulation of A mouth, after fastening, pull hand valve and put meta, manhole cover is fixed, and tightens each snap close of manhole, and manhole is closed.
