Description

Uncap and warn the anti-fall well lid of folded two-layer anti-theft

Technical field

The utility model relates to a kind of inspection well cover, and the utility model especially relates to one and to uncap warning folded two-layer anti-theft anti-fall well lid.

Background technology

Manhole well lid is convenient to make regular check on underground municipal pipeline to install the easy to maintenance and ancillary facility that arranges of management, ensures smooth traffic and personal safety.But also there is many deficiencies in current well lid:

1 existing well lid mostly is monolithic construction, and unlatching needs whole well lid to rotate or remove, and considers that load requirement well lid generally adopts cast iron to build and forms, in himself weight, so comparatively require great effort when opening;

2. remove for well lid and generally just arrange mobile warning sign afterwards, the vehicle of dealing is also a kind of security threat to down-hole maintainer;

3. there is strength deficiency and the short problem of life cycle in routine inspection well anti-drop net.

Summary of the invention

The purpose of this utility model overcomes the deficiencies in the prior art, provide a kind of be convenient to open safeguard, the strengthening alarm function collision prevention function is provided and there is the warning folded two-layer anti-theft anti-fall well lid of uncapping of anti-drop function when personnel go into the well maintenance.

According to the technical scheme that the utility model provides, the described anti-fall well lid of warning folded two-layer anti-theft of uncapping, annular base is provided with the upper support platform and lower support platform that are annular, the external diameter of lower support platform is less than the internal diameter of support platform, upper support platform overturns on passing through hinge and has the first upper lid, on the first upper lid by doubling hinge have the second upper lid, the second upper lid coordinates with the first upper lid and forms complete inspection shaft upper cover; Lower support platform has first time half of lid by lower upset hinge, first time half of lid has second time half of lid by lower doubling hinge, first time half of lid coordinates with second time half of lid and forms complete inspection shaft lower cover; And upper upset bearing pin and lower upset bearing pin are separately positioned on the diametric end positions of annular base.

The first fluorescence warning coating is equipped with at the soffit of the first upper lid and the soffit of the second upper lid.

The second fluorescence warning coating is equipped with at the soffit of first time half of lid and the soffit of second time half of lid.

The utility model is convenient to open and safeguard, the strengthening alarm function when personnel go into the well maintenance also provides collision prevention function, and the utility model has anti-drop function, and the utility model structure is simple, cost of manufacture is cheap, has promotion and application prospect widely.

Detailed description of the invention

Below in conjunction with specific embodiment, the utility model is described in further detail.

This anti-fall well lid of warning folded two-layer anti-theft of uncapping, annular base 1 is provided with the upper support platform 1.1 and lower support platform 1.2 that are annular, the external diameter of lower support platform 1.2 is less than the internal diameter of support platform 1.1, upper support platform 1.1 overturns on passing through bearing pin 3.1 and is hinged with the first upper lid 2.1, on first upper lid 2.1 passes through, doubling bearing pin 3.2 is hinged with the second upper lid 2.2, second upper lid 2.2 coordinates with the first upper lid 2.1 and forms complete inspection shaft upper cover, inspection shaft upper cover can carry out integrated overturn along upper upset bearing pin 3.1, inspection shaft upper cover can carry out doubling upset along upper doubling bearing pin 3.2, lower support platform 1.2 is hinged with first time half of lid 5.1 by lower upset bearing pin 4.1, first time half of lid 5.1 is hinged with second time half of lid 5.2 by lower doubling bearing pin 4.2, first time half of lid 5.1 coordinates with second time half of lid 5.2 and forms complete inspection shaft lower cover, inspection shaft lower cover can carry out integrated overturn along lower upset bearing pin 4.1, and inspection shaft lower cover can carry out doubling upset along lower doubling bearing pin 4.2, and upper upset bearing pin 3.1 and lower upset bearing pin 4.1 are separately positioned on the diametric end positions of annular base 1.

The utility model, relative to prior art, is first provided with inspection shaft lower cover (i.e. anti-weight lid), when losing of cover on inspection inspection shaft or after damaging, anti-falling stop thing or personnel can fall down manhole, improve the safety of manhole; Secondly, inspection shaft upper cover, inspection shaft lower cover and annular base 1 adopt hinged, enhance anti-theft feature; Again, because inspection shaft upper cover and inspection shaft lower cover all adopt folded, can open the second upper lid 2.2, second time half of lid 5.2 when being on the one hand and using as required or all open the second upper lid 2.2 and the first upper lid 2.1 and first time half of lid 5.1 and second time half of lid 5.2, it is quite convenient to use; On the other hand, single only need overturn the second upper lid 2.2 along upper doubling bearing pin 3.2, and the opening force of needs is smaller; And, inspection shaft upper cover and inspection shaft lower cover all adopt the form of splitting, after doubling is opened, the first fluorescence warning coating 6.1 at the inspection shaft upper cover back side, the second fluorescence warning coating 6.2 at the inspection shaft lower cover back side can remind vehicular traffic to note, can form stable gusseted on the other hand and prevent maintainer from being hit.

Under normal operating conditions, inspection shaft upper cover and inspection shaft lower cover form double-deck anti-fall well lid, ensure that urban operating mechanism normally runs and traffic safety.

The first fluorescence warning coating 6.1 is equipped with at the soffit of the first upper lid 2.1 and the soffit of the second upper lid 2.2; The second fluorescence warning coating 6.2 is equipped with at the soffit of first time half of lid 5.1 and the soffit of second time half of lid 5.2.When inspection shaft upper cover and the equal doubling of inspection shaft lower cover are opened, the first fluorescence warning coating 6.1 and the second fluorescence warning coating 6.2 form alarming sign outwardly, and warning nearby vehicle notices that well lid is opened.
