Abstract
The utility model announces a kind of adjustable height inspection well cover.Comprise cover plate of manhole, fixed frame and activity box, described cover plate of manhole is arranged on activity box; Described fixed frame is tubular, its inwall is fixed with multiple equally distributed outstanding supporting pin; Described activity box is tubular, and activity box engagement sleeves is contained in fixed frame, and a multilayer stepwise cotter way is respectively offered in position corresponding with supporting pin on activity box, under supporting pin is supported on certain the single order cotter way in multilayer stepwise cotter way.The utility model has the advantages that: cover plate of manhole can be adjusted in a plane with road surface all the time, and do not need again to transform inspection shaft system in road surface is repeatedly laid again; Be not afraid of environmental corrosion, the axis of activity box and fixed frame and radial bearing capacity greatly, are not easily destroyed when bearing the compression shock from cover plate of manhole for a long time, can ensure the overall safety and reliability used.
Description
Technical field
The utility model relates to a kind of road inspection well cover, in particular a kind of adjustable height inspection well cover.
Background technology
Inspection shaft is a kind of important infrastructure, many inspection shafts conveniently or all locate in the road due to the enlarging of road, due to the sedimentation of the laying of road or road, inspection shaft, make inspection well cover or outstanding the inside, lower than road surface, both dangerous also unsightly, also easily allow road surface rapid destruction around inspection well cover.
Notification number is had to be " the adjustable height inspection well cover " of CN203452100U in conventional art, the height on its application adjustment bolt adjusting base and ground and gradient, when ensureing to install, the surface of well lid is parallel to the ground, but owing to being be threaded between adjustment bolt and base, adjustment bolt is final stress point, when well lid bears compression shock for a long time, screw thread between adjustment bolt and base will be damaged, and then losing regulatory function, safety and reliability is poor, cannot meet instructions for use.Moreover inspection shaft work condition environment is severe, moist, the screw thread between adjustment bolt and base can be corroded and lose efficacy.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of adjustable height inspection well cover.
The utility model is by the following technical programs: a kind of adjustable height inspection well cover, comprises cover plate of manhole, and also comprise fixed frame and be arranged on the activity box on fixed frame, described cover plate of manhole is arranged on activity box; Described fixed frame is tubular, its inwall is fixed with multiple equally distributed outstanding supporting pin; Described activity box is tubular, and activity box engagement sleeves is contained in fixed frame, and a multilayer stepwise cotter way is respectively offered in position corresponding with supporting pin on activity box, under supporting pin is supported on certain the single order cotter way in multilayer stepwise cotter way.
It is further: the external diameter of described fixed frame the latter half expands gradually, and the axial cross section of fixed frame the latter half is up-narrow and down-wide right-angled trapezium.
Described supporting pin is no less than three, and supporting pin is uniformly distributed along the same sagittal plane of fixed frame.
Described supporting pin is perpendicular to the cylinder of fixed frame; Described multilayer stepwise cotter way comprises multiple circular port communicated with each other be opened on activity box wall, and the position of these circular ports raises from left to right successively.
Described activity box upper end extends outward the circle edge concordant with activity box upper surface.
Described cover plate of manhole is arranged in the deep gouge of activity box upper end, and cover plate of manhole upper surface is concordant with activity box upper surface.
The utility model has the advantages that: activity box maintains static, by controlling the lifting up and down of activity box with fixing, thus cover plate of manhole can be elevated accordingly along with the lifting on road surface, no matter road surface improve, the sedimentation of road surface or inspection shaft, cover plate of manhole can be adjusted in a plane with road surface all the time, and does not need again to transform inspection shaft system in road surface is repeatedly laid again; Activity box coordinates in insertion fixed frame, be connected with multilayer stepwise cotter way by multipair supporting pin between them, be not afraid of environmental corrosion, axis and the radial bearing capacity of activity box and fixed frame are large, not easily be destroyed when bearing the compression shock from cover plate of manhole for a long time, the overall safety and reliability used can be ensured.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the top view after removing cover plate of manhole in Fig. 1.
In figure: 1, cover plate of manhole; 2, activity box; 21, multilayer stepwise cotter way; 3, fixed frame; 31, supporting pin.
Detailed description of the invention
Be below a specific embodiment of the present utility model, existing the utility model is described in further detail by reference to the accompanying drawings.
As depicted in figs. 1 and 2, a kind of adjustable height inspection well cover, fixed frame 3 is in tubular, and the external diameter of its latter half expands gradually, and the axial cross section of fixed frame 3 the latter half is up-narrow and down-wide right-angled trapezium; Fixed frame 3 inwall is fixed with multiple equally distributed outstanding supporting pin 31, supporting pin 31 is perpendicular to the cylinder of fixed frame 3, is no less than three, and supporting pin 31 is uniformly distributed along the same sagittal plane of fixed frame 3, supporting pin 31 can be that bolt is connected with fixed frame 3, is convenient to dismounting; Activity box 2 is in tubular, and activity box 2 engagement sleeves is contained in fixed frame 3, and a multilayer stepwise cotter way 21 is respectively offered in position corresponding with supporting pin 31 on activity box 2, under supporting pin 31 is supported on certain the single order cotter way in multilayer stepwise cotter way 21; Multilayer stepwise cotter way 21 comprises multiple circular port communicated with each other be opened on activity box 2 wall, and the position of these circular ports raises from left to right successively; Activity box 2 upper end extends outward the circle edge concordant with activity box 2 upper surface, and cover plate of manhole 1 is arranged in the deep gouge of activity box 2 upper end, and cover plate of manhole 1 upper surface is concordant with activity box 2 upper surface.
