Summary of the invention
Technical matters to be solved by this invention provides 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, be arranged on the manhole cover in this flange and be located at handle on the described manhole cover, between described manhole cover lateral surface top and the described flange medial surface by snap lock pearl fastening.
In the technique scheme, scheme can also be more specifically: described manhole cover end face is fixed with support, and described handle is connected with rotating shaft on being located at this support, and this rotating shaft also is connected with the lifting kelly, the other end of described lifting kelly is connected on hinge and puts, and consists of 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 the described manhole cover, be provided with the rotating shaft of horizontally set in the described hinge cover, the rotating shaft of the rotating shaft of this horizontally set and vertical setting of its underpart forms T-shaped body, the rotating shaft of described vertical setting be contained in for bearing adapter plate that the storage tank tank body is connected on the bearing axle sleeve in.
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, and 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; Be provided with seal ring between described manhole cover and the described flange, the sealing circle is located at the bottom of described snap lock pearl draw-in groove.
Because adopt technique scheme, the present invention has following beneficial effect:
1, owing to fastening by the snap lock pearl between manhole cover lateral surface top and the flange medial surface, when covering, only need be pressed into gently by the hadle manhole cover that the snap lock pearl can fasten in the flange, operate very convenient, safe and reliable; And common manhole device has one section straight figure, and the manhole cover locking normally screws with screw rod, and the face of screwing has the dead angle, and this manhole bottom surface is consistent with the shape of storage tank contact position, and contact surface is smooth smooth, does not have the dead angle.
2, owing to being to promote the unlatching manhole cover by promoting kelly and rotating shaft cover link arm, therefore, after promoting kelly locking ascent direction, rotating shaft cover link arm can drive the manhole cover transverse rotation; Open manhole cover during longitudinal movement, during transverse rotation manhole cover is moved on to side, do not hinder the cleanup crew to enter manhole storage tank is cleaned, operate so whole process more easy and convenient.
3, because seal ring is located at the bottom of described snap lock pearl draw-in groove, the protection seal ring is not damaged.
