Abstract
The utility model belongs to the cover board field of industrial working or Urban Underground pipe gallery escape hatch, provides a kind of simple and reliable pipe gallery escape hatch's cover board.Cover board body produces portal framework by structural steel and steel deck-plate forms, and hinge is arranged in cover board body side, and special construction triangle lockset, centre setting limit drag-line is arranged in corresponding other side.Special triangle lockset is made of angle steel, internally-opened handle, drive rod and external key hole and rain-proof cover.The utility model relates to simple and reliable, avoid common cover difficult since corrosion causes to open, improve the reliability of the escaping function of manhole.
Description
Technical field
The utility model belongs to the cover board field of industrial working or Urban Underground pipe gallery escape hatch.
Background technique
Currently, domestic pipe gallery construction is in high number developing stage, personnel's personal safety is most important in piping lane.It is sending out
When raw emergency, such as the disasters such as fire, water logging, need to guarantee that piping lane internal staff can evacuate on ground in time.It is comprehensive
Piping lane escape hatch is mainly exactly when causing danger, and support personnel smoothly withdraws inside piping lane, while being considered in positive reason
Routine maintenance and maintenance work can be carried out under condition from manhole external opening into such as piping lane.Existing piping lane escape hatch cover board lacks
Relevant standard collective drawings way, the more difficult requirement for taking into account inside and outside opening or unfolding mode reliability are relatively low in actual use.
The utility model proposes a kind of simple and reliable cover boards to open combination, has wide applicability.
Utility model content
The utility model provides a kind of simple and reliable integrated pipe to solve pipe gallery internal staff escape demand
Corridor cover plate for manhole.
The utility model adopts the following technical scheme realizes:
(1) a kind of reliable inside and outside pipe gallery escape hatch's cover board opened, it is characterised in that it include manhole hole wall and
Cover board body above it, cover board body produces portal framework by structural steel and steel deck-plate forms, the setting of cover board body side
Special construction triangle lockset, centre setting limit drag-line is arranged in hinge, corresponding other side.Special triangle lockset is by angle steel, interior
Opened handle and external key hole and rain-proof cover composition
(2) it in piping lane emergency escape, can be opened by inside, metal lock tongue is rotated by internally-opened handle, is pushed out
It uncaps plate.Overall structure is simple and easy to control, guarantees escape effect.
(3) when needing to enter from external manhole when piping lane overhauls, rain-proof cover is opened by professional, uses the three of customization
Angle key opens cover board, easy to operate.
The beneficial effects of the utility model are:
It itself provides the escaping function of piping lane, in case of emergency, avoided to the full extent due to mechanical realization side
In face of the influence of escape, at the same the functions such as antitheft, dropproof that part is basic, the underground integrated pipe suitable for city and plant area
Escape hatch's cover board of corridor and similar underground structure.
Detailed description of the invention
Fig. 1 is the diagrammatic cross-section of the utility model
Fig. 2 is the portion the A enlarged drawing of Fig. 1
In figure: 1- cover assembly, 1.1- structural steel produce entrance lower frame, and 1.2- structural steel produces entrance upper box
Frame, 2- hinge/hinge, 3- triangle lock assembly, 3.1- angle steel, 3.2- metal lock tongue, 3.3- internally-opened handle, 3.4- drive rod,
3.5- triangular key hole and rain-proof cover, 4- square steel, 5- limit drag-line, 6- reinforcing bar semi-ring pad, 7- manhole hole wall.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Figure 1, a kind of reliable inside and outside pipe gallery escape hatch's cover board opened, including manhole hole wall -7, hole wall
Reinforcing bar semi-ring pad -6 are arranged in top surrounding, and covering plate structure steel entrance lower frame -1.1 uses welding manner and reinforcing bar
Semi-ring pad -6 is fixed.It is produced by hinge/hinge -2 with structural steel the side that structural steel produces entrance upper frame -1.2
Entrance lower frame -1.1 is connected, and other side is produced entrance lower frame -1.1 by triangle lock assembly -3 and structural steel and held in the mouth
It connects.
Top steel structural steel, which is produced, is arranged square steel among entrance upper frame -1.2, to enhance the pressure-bearing of cover board entirety
Ability, upper and lower part frame centre are connected by limit drag-line -5, avoid cover board entirety open angle excessive.
As shown in Fig. 2, triangle lock assembly -3 blocks metal lock tongue -3.2, metal by the angle steel -3.1 being located in lower frame
Internally-opened handle -3.3 is arranged in the opposite side of lock tongue, and metal lock tongue and internally-opened handle are fixed on the bottom of drive rod 3.4, drive rod and three
Angle keyhole and rain-proof cover -3.5 are fixed on upper frame.
