Description
Technical field
The utility model relates to by the lid of the mobile fastening piece setting pressure container on rocking arm, especially a kind of lid-open device of manhole cover.
Background technique
We know, manhole is the passage that people enters maintenance in pressurized container.While carrying out maintenance work in people enters manhole, need to dismantle manhole cover, after manhole cover dismounting, need manhole cover to remove.For example, in on December 28th, 2013 disclosed CN203348531U Chinese utility model patent specification disclosed " a kind of manhole cover arm cap-opening mechanism ", comprise arm, bearing cap, flange, bearing, sleeve pipe and hanging mechanism, sleeve pipe is arranged on manhole cover one side, sleeve pipe has flange up and down, there is bearing cap in flange outside, bearing cap is fixed on sleeve pipe upper and lower end face by double-screw bolt, arm is L-type, arm one end is arranged in sleeve pipe by two bearings, the arm the other end has hanging mechanism, and arm tangles manhole cover by hanging mechanism; Its hanging mechanism is hook, links up with and is arranged on arm end by link; Manhole cover is provided with and is linked with.This manhole cover with arm cap-opening mechanism after manhole cover is uncapped by pulling arm manhole cover can be opened, operate very simple.But in above-mentioned open file, its suspension hook ring is to adopt bar one end to be bent into hook, the other end needs machining screw, and course of working is complicated, and cost is higher; In addition, manhole cover is provided with to be linked with and exists the insecure deficiency of hanging.
Summary of the invention
In order to overcome suspension hook processed complex in prior art, cost is higher and suspender belt exists unserviceable deficiency, the utility model provides the lid-open device of the easy and manhole cover that cost is low, parts are safe and reliable of a kind of component processing.
The utility model solves the technological scheme that its technical problem adopts: a kind of lid-open device of manhole cover, it comprises flange, manhole cover, arm, sleeve pipe and hanging mechanism, described sleeve pipe is fixedly connected on a side of flange, described arm is inverted L shape, one end of arm is rotated and is assemblied in described sleeve pipe, the other end of arm offers attachment hole, it is characterized in that: described hanging mechanism comprises a double-screw bolt and suspension ring, described suspension ring are fixedly connected on manhole cover, in the center portion of suspension ring, offer a bolt hole, one end of described double-screw bolt through the attachment hole on arm by the spacing end at arm of upper cap nut, the other end of described double-screw bolt is spacing on suspension ring by lower nut through the bolt hole on suspension ring.
The described arm that is inverted L shape, its bending place is fixedly connected with a strut.
Described suspension ring are ∏ type, and the both sides of its ring body are fixedly connected with described manhole cover.
What hanging mechanism of the present utility model adopted is the structure of double-screw bolt and nut, and both are all standard piece, can directly purchase, and cost is lower.Suspension ring adopt sheet material to bend shaping, easy to process, connect and use reliably.Complete when manhole cover dismounting, only need pull arm just manhole cover can be removed, easy to operate, can reduce greatly workman's manipulation strength.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is a kind of structural representation of the present utility model.
Mark in figure: 1. flange, 2. manhole cover, 3. pedestal, 4. sleeve pipe, 5. arm, 6. attachment hole, 7. upper cap nut, 8. double-screw bolt, 9. bolt hole, 10. lower nut, 11. suspension ring, 12. struts.
Embodiment
In Fig. 1, a kind of lid-open device of manhole cover, it comprises flange 1, manhole cover 2, arm 5, sleeve pipe 4 and hanging mechanism.
Flange 1 is arranged on the body of pressurized container.Manhole cover 2 is to adopt conventional bolt to be connected with flange 1.
In Fig. 1, sleeve pipe 4 is through a pedestal 3, to be weldingly fixed on a side of flange 1.
As shown in Figure 1, arm 5 is inverted L shape, and one end of arm 1 is rotated and is assemblied in sleeve pipe 4, and the other end of arm 5 offers attachment hole 6.
In Fig. 1, hanging mechanism comprises a double-screw bolt 8 and suspension ring 11.
As shown in Figure 1, suspension ring 11 are ∏ type, are to adopt sheet material to bend shaping, and the both sides of the ring body of suspension ring 11 and manhole cover 2 are welded and fixed.In the center portion of suspension ring 11, offer a bolt hole 9.
In Fig. 1, one end of double-screw bolt 8 is fastening spacing in the end of arm 5 by upper cap nut 7 through the attachment hole 6 on arm 5, and the other end of double-screw bolt 8 is fastening spacing on suspension ring 11 by lower nut 10 through the bolt hole 9 on suspension ring 11.Reliable in order to connect, upper cap nut 7 adopts double nut.
Because manhole cover 2 weight are heavier, in order to guarantee arm 5 reliably workings, in the bending place of arm 5, be welded and fixed a strut 12.This strut 12 has effectively prevented that arm 5 from too much causing distortion because of load-bearing.
The utility model is after manhole cover 2 demolitions, pull arm 5 to rotate at sleeve pipe 4, manhole cover 2, under double-screw bolt 8, suspension ring 11 and upper cap nut 7, the lower nut 10 of arm 5 the other end are hung jointly, is removed with the rotation of arm 5, easy to operate, reduced manipulation strength.
