Description
Technical field
The utility model relates to inspection shaft security protection matching technology field more particularly to a kind of anti-drop nets.
Background technique
A lot of underground pipings, such as sewer, underground gas pipeline, water supply pipe, power pipe are had in urban construction
Road, communication conduit, national defence pipeline etc., these pipelines will have the outlet for leading to ground every one section, by pipeline to ground
This section is known as inspection shaft, and catch pit port is usually concordant with ground, it is therefore desirable to which a lid is inspection shaft for the lid of lid inspection shaft
Lid.Inspection well cover is usually made of materials such as reinforced concrete, metal, reinforced plastics, and shape is based on round and rectangular.In inspection well cover
On, it generally to indicate the purposes of down-hole pipe and manage and support the information such as unit and phone.
Existing inspection well cover mostly uses cast iron to be made greatly, is often stolen, loses tight since material has recycling to be worth
Weight, if the careless slightly loss for not noticing inspection shaft of pedestrian and make a misstep, less serious case will cause injury, and severe one will be dead.
Therefore, occurs a kind of anti-drop net being mounted in inspection shaft on the market.In the complete situation of inspection well cover, anti-drop net is not acted as
With；After inspection well cover is stolen to be lost or is broken, anti-drop net is placed in catch pit port, plays the role of preventing pedestrian from falling.
And general anti-drop net will have been in inspection shaft after installation, and anti-drop net itself may after long-time
Aging can be generated, and at this moment if inspection shaft losing of cover, and pedestrian passes by and may step on brokenly anti-drop net above, due to anti-fall
Only one layer of net, pedestrian can still fall into inspection shaft after stepping on brokenly, so that the effect of protection is bad.
Utility model content
The purpose of this utility model is to provide a kind of anti-drop net, have the advantages that protection effect is preferable.
The above-mentioned purpose of the utility model has the technical scheme that
A kind of anti-drop net is arranged including framework, along the length direction of framework in the intracorporal multiple dictyosomes of frame, the framework
Including two annulus being coaxially disposed up and down and the more root posts being arranged between two annulus, it is provided on the dictyosome outer ring
Multiple becket bridles are provided with multiple hooks with becket bridle mounting on the annulus and column, set in the space that the column surrounds
It is equipped with ring, the ring is coaxial with annulus and the diameter of ring is less than the diameter of annulus, wears between the ring and column
There is the sleeve for connecting ring with column, the fixing piece for being fixed on framework in inspection shaft is provided in the sleeve.
Implement above-mentioned technical proposal, when anti-drop net is mounted in inspection shaft, is articulated in the side on hook by becket bridle first
Multiple dictyosomes are successively connected on annulus and column by formula from the bottom up, then put framework in inspection shaft at leisure into, so that
Annulus, column and dictyosome are in inspection shaft, and finally framework is fixed in inspection shaft with fixing piece.Make after being arranged in this way
Obtaining in inspection shaft has multilayer dictyosome, so that there is multilayer proofing at inspection shaft, in dictyosome aging, multilayer dictyosome is also still relative to one layer
Dictyosome has preferable protection effect.
Further, the fixing piece includes the inserted link being slidably arranged in sleeve, and the length of the inserted link is less than sleeve
Length is provided with so that inserted link has the elastic component of the movement tendency outside sleeve always in the sleeve.
Implement above-mentioned technical proposal, when fixed, the chisel hole corresponding with inserted link quantity first on the inner wall of inspection shaft, then
The position of sleeve alignment hole is slid into, when inserted link slides into the position of just positive device to hole, under the driving of elastic component, inserted link meeting
It is slided outside toward sleeve, so that inserted link just inserts in the hole, so that framework is fixed in inspection shaft, reaches fixation and conveniently imitate
Fruit.
Further, the sleeve is arranged close to the end seals of ring, and the elastic component includes the envelope being arranged in sleeve
First spring at mouth end, the other end of first spring are connect with inserted link.
Implement above-mentioned technical proposal, is allowed at the first spring first in the compressible state, when inserted link slides into just face
When the position in hole, due to the characteristic that first spring itself has, inserted link can be pushed to slide along the length direction of sleeve, thus
By one section of release sleeve of inserted link, achieve the effect that realize fixed frame.
Further, the anti-drop assembly for preventing inserted link from completely disengaging sleeve is provided in the sleeve.
Implement above-mentioned technical proposal, the setting of anti-drop assembly allows frame so that inserted link will not completely disengage sleeve, to reach
The effect that body is fixed relatively stable in inspection shaft.
Further, the casing being connected to sleeve inner, institute are provided on the sleeve outer wall between column and ring
The length direction for stating casing is consistent with the length direction of column, and described sleeve pipe is arranged far from sleeve end closure, the anti-drop assembly
Including the countercheck rod that the second spring of the sealing end of casing is arranged in and is arranged in second spring, along vertical on the inserted link
Directly the jack for countercheck rod insertion is offered in inserted link axially direction.
Implement above-mentioned technical proposal, when the length direction cunning under driving of the inserted link in second spring in sleeve along sleeve
When dynamic, the countercheck rod in casing can also contradict always on the bar wall of inserted link under the driving of second spring, when inserted link slides into
When at the just face jack of the end of countercheck rod, due to the blocking without inserted link bar wall, countercheck rod can be in the work of second spring
It is inserted into jack straight under, and inserted link can not continue to slide in sleeve under the blocking of countercheck rod at this time, so that reaching makes
Inserted link is obtained without departing from the effect of sleeve.
Further, the countercheck rod is provided with ball close to the end of inserted link.
Implement above-mentioned technical proposal, the setting of ball is so that countercheck rod will not be to the cunning of inserted link when inserted link slides in sleeve
It is dynamic to affect greatly, so that inserted link slides more smooth.
Further, the framework surface is coated with antirust agent.
Implement above-mentioned technical proposal, after coating antirust agent, framework can slow down the speed got rusty, and extend framework to reach
The effect of service life.
Further, the dictyosome is woven by nylon rope.
Implement above-mentioned technical proposal, since nylon rope hardness is preferable and antiseptic property is higher, so that dictyosome aging
It slows, to increase the service life of dictyosome.
In conclusion the utility model has the following beneficial effects:
One, the setting of multilayer dictyosome is so that there is multilayer proofing at inspection shaft, and in dictyosome aging, multilayer dictyosome is also still opposite
There is preferable protection effect in one layer of dictyosome；
Two, the setting of second spring and countercheck rod allows framework in basement so that inserted link will not completely disengage sleeve to reach
The effect for fixing relatively stable in well.
