Summary of the invention
Technical matters to be solved by this invention is to provide a kind of storage tank manhole device, and it can solve the locking closure inconvenient operation of existing storage tank manhole, the problem that safe reliability is poor.
In order to address the above problem, technical scheme of the present invention is: it includes flange, is arranged on the manhole cover in this flange and is located at the handle on described manhole cover, between described manhole cover lateral surface top and described flange medial surface, fastens by snap lock pearl.
In technique scheme, scheme can also be more specifically: described manhole cover end face is fixed with support, and described handle is connected with the rotating shaft being located on this support, and this rotating shaft is also connected with lifting kelly, the other end of described lifting kelly is connected on hinge and puts, and forms self-locking device; The two ends of described hinge cover are respectively equipped with rotating shaft cover link arm, the other end of described rotating shaft cover link arm is connected with the support on described manhole cover, in described hinge cover, be provided with the rotating shaft of horizontally set, the rotating shaft of the rotating shaft of this horizontally set and longitudinal setting of its underpart forms T-shaped body, and the rotating shaft of described longitudinal setting is contained in the bearing axle sleeve on the bearing adapter plate for being connected with storage tank tank body.
Further: described handle includes handgrip and is located at the joystick of handgrip both sides, and described joystick bottom is kink, the described rotating shaft socket of the bending place of described joystick and described support.
Further: the rotating shaft of described horizontally set is provided with bail, described lifting kelly is provided with the draw-in groove corresponding with described bail with the end that is connected on described hinge cover.
Further: described flange medial surface is provided with described snap lock pearl draw-in groove; Described flange medial surface is provided with described snap lock pearl draw-in groove; Between described manhole cover and described flange, be provided with seal ring, sealing circle is located at the bottom of described snap lock pearl draw-in groove.
Owing to adopting technique scheme, the present invention has following beneficial effect:
1,, owing to fastening by snap lock pearl between manhole cover lateral surface top and flange medial surface, in the time covering, only need be pressed into gently snap lock pearl in flange by hadle manhole cover can fasten, and operates very convenient, safe and reliable; And common manhole device has one section of straight figure, manhole cover locking normally screws with screw rod, and the face of screwing has dead angle, and this manhole bottom surface is consistent with the shape of storage tank contact position, and contact surface is smooth, does not have dead angle.
2,, owing to being to promote unlatching manhole cover by lifting kelly and rotating shaft cover link arm, therefore, when promoting after kelly locking ascent direction, rotating shaft cover link arm can drive manhole cover transverse rotation; When longitudinal movement, open manhole cover, when transverse rotation, manhole cover is moved on to side, do not hinder cleanup crew to enter manhole storage tank is cleaned, operate so whole process more easy and convenient.
3, be located at the bottom of described snap lock pearl draw-in groove due to seal ring, protection seal ring is not damaged.
