Description

Anti-gas explosion frame lid

Technical field

The utility model relates to a kind of anti-gas explosion frame lid, particularly about the shellproof manhole cover that takes off, prevents gas explosion of a kind of energy.

Background technology

Manhole cover is uneven because of end face and road surface in recent years, allow with passerby walk, very dangerous by bike, remove the life security of harm with passerby, it is injured more to cause the people to cause trouble, and forms the big secret worry of traffic safety.Burying underground of present various pipeline and culvert pipe is quite a lot of, and its pipeline and culvert pipe all can be reserved the pipeline manhole of maintenance pipeline, covers with manhole cover again, if biogas just the gas explosion phenomenon may take place too much in the manhole, causes the accident of manhole cover escape.

A kind of manhole cover module comprises: a ring seat, and its central authorities are formed with a hole, manhole with corresponding road, and on this ring seat, be equipped with a plurality of connecting holes, and be provided with most reference columns in the bottom of this connecting hole, and this reference column edge is embedded in the concrete ground; One pedestal, its central authorities form a hole, with the manhole of corresponding road, and its outer peripheral edges are the downward oblique cone wall of point gradually, and at the inner edge of this hole, be provided with lip portions, and make this pedestal be equipped with most fixing holes, make each fixing connecting hole of a corresponding ring seat respectively of pricking, after bolt passes the fixing hole of this pedestal, be screwed together in the connecting hole of this ring seat, and pedestal is anchored on the ring seat; And a manhole lid, the hole aperture of this pedestal that coincide in the hole of inserting this pedestal, and is cross-placed on the lip portions of this hole identically.Though, above-mentioned a kind of manhole cover module can solve manhole cover because of the rugged problem of end face and road surface, but adaptation is poor between manhole cover and the frame lid, is not provided with the shellproof function of taking off, preventing gas explosion, when if vehicle when running over manhole cover gas explosion takes place, easily cause the accident of manhole cover escape

The utility model proposes a kind of anti-gas explosion frame lid, to improve above-mentioned shortcoming at above-mentioned problem.

The utility model content

Problem to be solved in the utility model provides a kind of anti-gas explosion frame lid, and the groove that the ring wall of a ring seat is prolonged a T type of vertical direction embeds the snap close of this skeleton frame, to reach anti-gas explosion, shellproof function of taking off.

Another purpose of the present utility model provides a kind of anti-gas explosion frame lid, utilizes a scrobicular ring snare of lid bottom to go into ring seat, so that lid and ring seat adaptation are good.

A purpose more of the present utility model provides a kind of anti-gas explosion frame lid, utilizes to promote packing ring, to adjust the level height of lid, flushes with the road surface, to increase safety.

Another purpose of the present utility model provides a kind of anti-gas explosion frame lid, can one lifting hole(eyelet) be set in lid, ring seat, and use chain that lid, ring seat are sling, to increase convenience.

For reaching above-mentioned purpose, the utility model provides a kind of anti-gas explosion frame lid, it goes into ring seat with the scrobicular ring snare of lid bottom, wherein again with the snap close of the groove embedding skeleton frame of a T type of ring seat, being provided with one between skeleton frame and ring seat carries and stretches packing ring, and this skeleton frame is provided with a plurality of screws, is provided with a hole and correspond to each this screw on this ring seat, and after can passing this hole with a locked assembly, be locked in the screw, carry and stretch packing ring to fix this.

Compared with prior art, the utlity model has following advantage: provide a kind of anti-gas explosion frame lid, particularly about the shellproof manhole cover that takes off, prevents gas explosion of a kind of energy.

The specific embodiment

Fig. 1 and Fig. 2 are the floor map and the sectional drawing of the anti-gas explosion frame lid of the utility model.A kind of anti-gas explosion frame lid 10 mainly is made up of a skeleton frame 12, a ring seat 14, a lid 16, the ring wall of ring seat 14 is prolonged the groove 18 of the T type that vertical direction is provided with, embedding is positioned at the outward extending snap close 20 of horizontal direction of 12 walls of this skeleton frame, this lid 16 is covered on this ring seat 12 at last, wherein lid 16, skeleton frame 12 materials can be nodular cast iron again.Therefore, can find that the utility model is stuck in snap close 20 edge of skeleton frame 12 in the groove 18 of T type of ring seat 14, prevents that to reach bullet from taking off, preventing the function of gas explosion.

Fig. 2 is the sectional drawing of the anti-gas explosion frame lid of the utility model, and Fig. 3 is a lid schematic rear view of the present utility model.One skeleton frame 12, the horizontal direction of its wall stretch out and are provided with a snap close 20; And the nearly outer rim place of skeleton frame 12 is provided with elliptical aperture; One ring seat 14 will be positioned at the groove 18 that ring wall prolongs a T type of vertical direction, be clipped in the groove 18 of T type with the snap close 20 with skeleton frame of rotation mode to the right or left; One lid 16, be provided with one and recommend the hole, so that this lid 16 is mentioned, its bottom has a scrobicular ring circle 22, this scrobicular ring circle 22 just can plug a rubber ring 24, and be inserted in this ring seat 14, present close-fitting situation with the design that utilizes scrobicular ring circle 22 and rubber ring 24, reach well secured effect, therefore, when vehicle runs over anti-gas explosion frame and covers 10, can prevent that lid 16 bullets take off here, can effectively ensure passing vehicle.

Fig. 4 promotes the packing ring sectional drawing for the anti-gas explosion frame lid of the utility model increases, between lid 16 and ring seat 14, be provided with one and promote packing ring 30, this skeleton frame outer annular edge is provided with screw 26, and correspond to promote on the packing ring 30 and also be provided with hole, pass this hole with screw 28 again after, be locked in the screw 26, can adjust the level height of lid, to cooperate the road surface to rise and fall, make with the road surface to flush, improve security performance.In lid 16, ring seat 14 lifting hole(eyelet) 32 can be set more, can use chain that lid 16, ring seat 14 are sling, to increase convenience.

Comprehensively above-mentioned, the utility model provides a kind of anti-gas explosion frame lid, owing to the groove of a T type of ring seat is bumped into the snap close of skeleton frame, again the scrobicular ring snare of lid bottom is gone into ring seat, reaching well secured effect, and prevent that vehicle ' is out-of-date, the sound takes place, and produces noise; On the other hand, can prevent that more the lid spring from flying out, and reduces hazard event.In addition, carry and stretch packing ring if between skeleton frame and ring seat, be provided with one, can be more smooth-going with the road surface at short notice, it is injured to avoid causing the common people to cause trouble, and forms the big secret worry of traffic safety.

More than disclosed only be several specific embodiment of the present utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection domain of the present utility model.
