Abstract
The utility model discloses a kind of semi-open type ductile cast iron manhole cover, comprise the well seat of rounded setting, described well seat is provided with the first well lid and the second well lid that adapt with well seat opening, first well lid and the second well lid axisymmetricly semicircle are arranged, described first well lid is being provided with bellmouth with the second well lid contact site, second well lid is provided with socket in contact site, and bellmouth and socket are connected together.The utility model is optionally opened and closedown by the first well lid and the second well lid, ensure that well seat opening can not be excessive owing to opening wide, causes potential safety hazard.Meanwhile, the first well lid after separation and the second well lid, its weight reduces by half, and people, when opening, save time, laborsaving, simple to operate.
Description
Technical field
The utility model relates to a kind of well lid, specifically a kind of semi-open type ductile cast iron manhole cover.
Background technology
Well lid, for hiding road or family's middle-deep well, prevents people or object from falling.The gross weight of existing ductile cast iron manhole cover and base is generally within the scope of 50-130kg, ensure that well lid has resistance to compression, bending resistance, shock proof intensity in use, there will not be after Long-Time Service well lid crushed and damage phenomenon, stop the generation of " black hole, city " accident.But general municipal construction, maintenance or water drainage time, need well lid to open, now, opening of well lid be time-consuming, effort, inconvenient people's operation.Meanwhile, also some opening completely due to well lid, has occurred that a lot of neglectful people fall into the situation in shaft bottom, has occurred potential safety hazard.In order to avoid existing situation produced problem, now provide a kind of new technical scheme.
Utility model content
The purpose of this utility model be to provide one safely, save time, labour-saving semi-open type ductile cast iron manhole cover.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of semi-open type ductile cast iron manhole cover, comprise the well seat of rounded setting, described well seat is provided with the first well lid and the second well lid that adapt with well seat opening, first well lid and the second well lid axisymmetricly semicircle are arranged, described first well lid is being provided with bellmouth with the second well lid contact site, second well lid is provided with socket in contact site, and bellmouth and socket are connected together.
Described bellmouth is the indented notch be provided with at the straight flange of the first well lid, and described socket is that the zigzag be provided with at the second well lid straight flange is protruded, and zigzag is protruded and is fastened on indented notch.
The described first well lid circular arc side corresponding with the second well lid is equipped with jut, and protruding part is in the groove that well seat circumference is provided with relatively, and jut is flexibly connected by bolt with groove.
Described first well lid and the second well lid upper surface are equipped with open slot.
The beneficial effects of the utility model: the utility model is optionally opened and closedown by the first well lid and the second well lid, ensure that well seat opening can not be excessive owing to opening wide, cause potential safety hazard.Meanwhile, the first well lid after separation and the second well lid, its weight reduces by half, and people, when opening, save time, laborsaving, simple to operate.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the utility model structural representation;
Fig. 2 is that the utility model first well lid is separated schematic diagram with the second well lid;
Fig. 3 is the utility model bellmouth and socket partial enlargement structural representation.
Detailed description of the invention
As Fig. 1, a kind of semi-open type ductile cast iron manhole cover, comprises the well seat 10 of rounded setting, and well seat 10 is stamped the first well lid 11 and the second well lid 12 adapted with well seat opening, the utility model well lid material all uses ductile iron to make.First well lid 11 and the second well lid 12 axisymmetricly semicircle are arranged, both cooperatively interact and cover on well seat 10, the first well lid 11 circular arc side corresponding with the second well lid 12 is equipped with jut 15, jut 15 is positioned at the groove 16 that well seat 10 circumference is provided with relatively, jut 15 is flexibly connected by bolt 18 with groove 16, and this design can make the first well lid 11 and the second well lid 12 be rotated by bolt 18.First well lid 11 is provided with bellmouth 13 in two straight flange contacts site with the second well lid 12, and the second well lid 12 is provided with socket 14 in contact site, and bellmouth 13 and socket 14 are connected together.Open slot 17 is equipped with at the first well lid 11 and the second well lid 12 upper surface.Relative to existing well lid, the utility model first well lid 11 and the second well lid 12 all can be opened as required, or open wherein one or two and all open.People, by open slot 17 pull-up first well lid 11 and the second well lid 12, when needs are closed, first put down the first well lid 11, then the socket 14 putting down the second well lid 12, second well lid 12 are stuck in bellmouth 13 li, mutually engages, can not move each other.
As the embodiment of the utility model the best, as Fig. 2 and Fig. 3, bellmouth 13 is the indented notch being located at the first well lid 11 straight flange place, and socket 14 is that the zigzag being located at the second well lid 12 straight flange place is protruded, and zigzag is protruded and is fastened on indented notch.Certainly, bellmouth 13 and socket 14 also can be other shapes, as square, arc etc.
As Fig. 3, the utility model bellmouth 13 is indented notch of a depression, has a plane bottom it, can play the effect supporting socket 14, make socket 14 uniform force, can not continue to whereabouts due to gravity.The degree of depth of bellmouth 13 and the height of socket 14 adapt simultaneously.
Working method: when needing to close, first put down the first well lid 11, then the socket 14 putting down the second well lid 12, second well lid 12 is stuck in bellmouth 13 li, mutually engages.When needing to open, people are by open slot 17 pull-up second well lid 12 and the first well lid 11.Above-mentionedly selectively to open and closedown, ensure that well seat 10 opening can not be excessive owing to opening wide, cause potential safety hazard.Meanwhile, the first well lid 11 and the second well lid 12 after separation, its weight reduces by half, and people, when opening, save time, laborsaving, simple to operate.
Above content is only to the utility model structure example and explanation; affiliated those skilled in the art make various amendment to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the structure of utility model or surmount this scope as defined in the claims, protection domain of the present utility model all should be belonged to.
