Description
Technical field
Drainage pipeline networks equipment technical field technical field is the utility model is related to, specifically a kind of easy care type vibration proof is prevented
Fall manhole cover.
Background technology
In urban underground water drainage pipe net, for ease of drawing maintenance to the clear of drainage pipeline networks, each certain distance sets an inspection
Well is looked into, is generally located under road.Gateway of the manhole cover as each inspection shaft, while as a part for road, its structure
Make, open the features such as difficulty, tightness be related to drainage pipeline networks can good operation, road vehicle road-ability and pedestrian
Safety.
The usual way of present situation catch basin cover is to use a round manhole cover, directly prevents on well seat, utilizes well lid itself
Weight realize tightness, one or two duck eye reserved on well lid be used for open manhole cover.
The deficiency of existing way is：(1) easily become silted up knot for well lid heaviness and periphery, and unlatching difficulty is very big, and well often occurs
Lid is not opened, or need to use the openable situation in equipment breakage well lid side, is highly detrimental to the clear of subdrainage pipe network and is drawn dimension
Shield；（2）For well lid due to only leaning on gravity and frictional force to fasten, fastening effect is poor, and when vehicle rolls, easily vibration, influences vehicle
Comfortableness and security.（3）Due to lacking locking device, well lid easily lacks, and is easily washed open by flood during heavy rain, pole is caused to pedestrian
Big potential safety hazard.
Based on the deficiency of existing inlet for stom water, the utility model researches and develops a kind of brand-new equipment, a kind of easy care type vibration proof
Fall arrest manhole cover, by Manhole cover lock on pit shaft, solve the problems, such as that its unlatching, vibration proof, anti-pedestrian fall.
The content of the invention
The purpose of this utility model is to provide a kind of easy care type vibration proof fall arrest manhole cover, to solve the above-mentioned back of the body
The problem of being proposed in scape technology.
To achieve the above object, the utility model provides following technical scheme：
A kind of easy care type vibration proof fall arrest manhole cover, including manhole cover main body, the manhole cover main body are set
Three circular arc being angularly evenly arranged holes are equipped with, and the periphery setting in circular arc hole is fluted, the size in the circular arc hole is can
Go deep into hand sizes design；Also include using three internal thread blocks for being easy to finger manipulation, inspection is stretched into internal thread block bottom
Look into the circular arc hole of well lid main body, internal thread block top is placed on the groove on circular arc hole periphery, in addition to uses three bands
Expand termination screw rod, band expansion termination screw rod expansion termination be embedded in pit shaft, band expand termination screw rod screw rod top and
Internal thread block is threadedly coupled；Limiting component is provided with the band expansion termination screw rod.
As further program of the utility model：Flushed at the top of the internal thread block with manhole cover body surfaces.
As the utility model further scheme：Anti-fall be caught is linked with three bands expansion termination screw rod.
As the utility model further scheme：The manhole cover main body is made of spheroidal graphite cast-iron.
As the utility model further scheme：The internal thread block, band expansion termination screw rod, expansion termination and
Positioning attachment is made of steel.
Compared with prior art, the beneficial effects of the utility model are：The utility model provides a kind of easy care type vibrationproof
Dynamic fall arrest manhole cover, structure are novel；The utility model realizes well lid and pit shaft one, well lid lightweight, fastening, safety, peace
It is small to fill workload, it is applied widely, you can applied to new inspection shaft, it can also be used to the transformation to existing inspection shaft.

Embodiment
The technical scheme of this patent is described in more detail with reference to embodiment.
Refer to Fig. 1-4, a kind of easy care type vibration proof fall arrest manhole cover, including manhole cover main body 1, internal thread
Block 2, band expansion termination screw rod 3, expansion termination 4, positioning attachment 5, anti-fall 6, circular arc hole 7 and the well lid groove 8 of being caught；The inspection
Look into well lid main body 1 and be provided with three circular arc being angularly evenly arranged holes 7, and the periphery in circular arc hole 7 sets fluted, internal thread
The bottom of block 2 is stretched into the circular arc hole of manhole cover main body 1, and the top of internal thread block 2 is placed on the groove on the periphery of circular arc hole 7
On, in addition to using three band expansion termination screw rods 3, the expansion termination 4 with expansion termination screw rod 3 is embedded in pit shaft, with swollen
The screw rod top of swollen termination screw rod 3 is threadedly coupled with internal thread block 2；Limiting section is provided with the band expansion termination screw rod 3
Part 5；The top of internal thread block 2 flushes with the surface of manhole cover main body 1；Hung on three bands expansion termination screw rod 3
Have and anti-fall be caught 6；The manhole cover main body 1 is made of spheroidal graphite cast-iron；The internal thread block 2, band expansion termination screw rod
3rd, expand termination 4 and positioning attachment 5 and manhole cover main body described in the present embodiment 1 is made using spheroidal graphite cast-iron system using steel
Into internal thread block 2, band expansion termination screw rod 3, expansion termination 4 and positioning attachment 5 are made of steel；Described inspection
The specification of well lid main body 1 is：It is a diameter of 74 centimetres, thick 2 centimetres；The specification of described internal thread block 2 is block upper diameter 6
Centimetre, thick 1 centimetre, top sets five holes, and hole dia is 2 centimetres in bottom；The specification of described band expansion termination screw rod 3 is：
2 centimetres of diameter, horizontal direction grow 5 centimetres, vertical 15 centimetres of length；The specification of described positioning attachment 5 is：A diameter of 3 millimeters
