Abstract

The invention discloses an anti-dropping safe inspection well cover seat. The anti-dropping safe inspection well cover seat is characterized by consisting of an inspection well cover (1), an inspection well cast iron seat (2), an inspection well net cover (3) and a spiral spring (5). The inspection well net cover (3) with meshes is arranged under the inspection well cover (1) and movably connected with the inspection well cast iron seat (2). When the inspection well cover (1) is lost by accident, the inspection well net cover (3) under the inspection well cover (1) can prevent a pedestrian from dropping into the inspection well. According to the anti-dropping safe inspection well cover seat, the compressed red spring is further arranged between the inspection well cover (1) and the inspection well net cover (3), when the inspection well cover (1) is open, the red spiral spring extends and springs above the ground to more than one meter to warn people of the existence the inspection well mouth and dangers. The multiple safety settings can effectively guarantee the safety of pedestrians and traveling vehicles and avoids the tragedies due to the ill management of the inspection well cover.

Description

A kind of fall arrest manhole cage

Technical field

The invention belongs to the technical field of Seat for manhole cover, especially a kind of fall arrest manhole cage.

Background technology

The inspection shaft of urban road comprises that " rain, sewage, communication, tap water, natural gas, electric power, chemical industry etc. pipeline inspection shaft is the hole that make things convenient for engineering staff come in and go out of shielding for safeguarding that underground utilities are reserved at present.Use in the city and to manage the department of pipeline inspection shaft numerous, the quantity of pipeline inspection shaft is very big.Total all kinds of inspection shafts are 1,230,000 in the Wuhan City, belong to 18 accountability unit such as water utilities, electric power, communication, combustion gas.On densely populated avenue, inspection shaft mismanagement and the security incident that causes take place at any time, use the safety design of inspection shaft and safeguard procedures to remedy very necessity of managerial deficiency.But the design specifications of the urban road pipeline inspection shaft in the Shanghai City that industrial technology is leading does not provide the necessary security setting yet now.As above " the separate type Seat for manhole cover " of Haiti side's design standard on the closing in member of inspection shaft pit shaft, overlapping the pedestal basis, is Cover of inspection well and cast iron seat with the pavement of road design elevation at pedestal, central without any the safety precaution design.When the unexpected disappearance of Cover of inspection well, inspection shaft is as the tiger that eats the people.Changsha suddenly rained cats and dogs and caused road ponding more than 9 evening on March 22nd, 2013.Be coated with house towards a vast expanse of water, helvolus road, 21 years old girl Yang Lijun falls into sewer accidentally, is swept away by torrent immediately, and is missing.Do not salvaged yet to this girl on the 25th, do not know whether one is dead or alive.The sewer mouth well lid that meets accident may be washed away by too much too urgent rainwater, breeds disaster, and such report is of common occurrence, and walking reaches by bike because do not note meeting the injured people of the inspection shaft of no well lid just more.Design has the Seat for manhole cover of safe precaution measure, guarantees that pedestrains safety is necessary.

Summary of the invention

The objective of the invention is to overcome the deficiencies in the prior art, develop a kind of fall arrest manhole cage that has safe precaution measure.

Technical solution of the present invention is as follows:

1, a kind of fall arrest manhole cage is characterized in that, as shown in Figure 1, Seat for manhole cover is made up of inspection shaft lid 1, inspection shaft cast iron seat 2, inspection shaft square 3, helical spring 5.

2, as shown in Figure 2, inspection shaft square 3 is conical disk-like structure, and the bottom surface is the grid 6 of perforation, and the convenient rainwater of draining can prevent that also underground water from rising suddenly and sharply, and washes inspection shaft square 3 open from below; The conical disk-like structure design of inspection shaft square 3 when producing this part in batches, stacks easily and transports; The buttonhole 7 that symmetry is arranged on the dish edge of inspection shaft square 3, inspection shaft square 3 is realized flexibly connecting by the button column 4 on the boss of buttonhole 7 and inspection shaft cast iron seat 2: be buckled in when inspection shaft square 3 on the boss of inspection shaft cast iron seat 2, when turning an angle, the head of the bolt shape of button column 4 just is pressed on the both sides stria in the buttonhole 7, make inspection shaft square 3 firmly connect inspection shaft cast iron seat 2, movable connection method is convenient need be removed inspection shaft square 3 and prevent that the current accident from washing away inspection shaft square 3 during the use inspection shaft; The existence of inspection shaft square 3 when inspection shaft covers 1 accident and loses, is protected when making pedestrian and child's accident step into inspection shaft.

3, in the space of inspection shaft lid 1 and inspection shaft square 3, be provided with the helical spring 5 of compression, the lower end of helical spring 5 and inspection shaft square 3 fixedly secure, when inspection shaft lid 1 is taken away, the helical spring 5 of compression stretches upsprings, above ground level more than 1 meter, reminds the pedestrian to note existing uncovered inspection shaft mouth here.Particularly on the flood inundation on tracks road surface, when cannot see the inspection shaft mouth, the warning function that exceeds 5 couples of pedestrians of helical spring of the water surface and driving is obvious.

Description of drawings:

Fig. 1 is the sectional view of Seat for manhole cover, and Fig. 2 is inspection shaft square 3.

The specific embodiment:

Specific embodiments of the invention:

2, as shown in Figure 2, inspection shaft square 3 is conical disk-like structure, the bottom surface is the grid 6 of perforation, the buttonhole 7 that symmetry is arranged on the dish edge of inspection shaft square 3, inspection shaft square 3 flexibly connects by the button column 4 on the boss of buttonhole 7 and inspection shaft cast iron seat 2: be buckled in when inspection shaft square 3 on the boss of inspection shaft cast iron seat 2, when turning an angle, the head of the bolt shape of button column 4 just is pressed on the both sides stria in the buttonhole 7, makes inspection shaft square 3 firmly connect inspection shaft cast iron seats 2.

3, in the space of inspection shaft lid 1 and inspection shaft square 3, be provided with the helical spring 5 of the red polymer material of compression, the lower end of helical spring 5 and inspection shaft square 3 fixedly secure, when inspection shaft lid 1 is taken away, the helical spring 5 of compression stretches upsprings, above ground level more than 1 meter, remind the pedestrian to note existing uncovered inspection shaft mouth here.Particularly on the flood inundation on tracks road surface, when cannot see the inspection shaft mouth, the warning function that exceeds 5 couples of pedestrians of helical spring of the water surface and driving is obvious.
