Abstract

The utility model relates to a four-point iron-bolt locking type well cover of a sewer well, which is used for drainage facilities of the urban road. The utility model is composed of a well cover body 1, a set bar 2, a six-wall pile 3, a reinforcing belt 4 and a screw disk 5. The well cover has the advantages of reasonable design, reliable operation, good theft-proof effect, good tumbling resistance and strong anti-press performance, and is suitable for the popularization and application under the construction of drainage facilities of the road.

Description

4 iron bolt locking type catch pit well lids

Technical field:

The utility model relates to a kind of device that is used for the urban road drainage Facilities Construction.

Background technology:

Along with the fast development of national economic development, urban construction is maked rapid progress, and highway extends in all direction.In urban road construction, must be aided with supporting drainage, comprising the catch pit that is arranged on pavement of road middle part or side in a large number (also claiming " inspection shaft ").Yet, the well lid that adopted of road drainage well is the problem of especially municipal administration of people, vehicle supervision department's headache always for a long time, because the catch pit well lid is lost often or rolled by vehicular traffic and to renovate, sometimes then do not resetted, cause great inconvenience and danger for pedestrian and vehicle by artificial moving.At this problem, relevant department, scientific research personnel are transformed the structure of catch pit well lid, designed antitheft, the fixing well lid and being applied within the specific limits of multiple pattern, but these well lids comparatively complicated owing to structure, make and use reason such as convenient, antitheft inadequately, that compressive property is not ideal enough to apply to be restricted.

Summary of the invention:

The purpose of this utility model be to provide a kind of simple in structure, safe and reliable, can be antitheft, resistance to compression, 4 iron bolt locking type catch pit well lids not renovating.

The utility model is to realize like this.This kind catch pit well lid is made up of well lid main body, locking bolt, reinforce belt, helical disk, six wall stakes, be provided with six wall stakes in the well lid main body end face centre bore, be uniformly distributed with radial reinforce belt along the circumference between the Internal and external cycle on the well lid main body bottom surface, be provided with helical disk in the inner ring, helical disk top and six pilaster are one, and helical disk is meshed along the helicla flute on the uniform locking bolt of disc with 4 by the helical tooth on it.During use, this well lid is placed on the catch pit well head, interior six wall impact wrenchs with special use are inserted in the six wall stakes at helical disk top by well lid main body end face centre bore, pull helical disk clockwise, make that by the helical tooth on it inner helical disk locking bolt with its engagement is protruding, well lid and well head can be locked, otherwise can open.Because and the locking bolt that stretch out uniform along the well lid side carried on a shoulder pole the latch groove that is provided with on the well lid shoulder with well head and closely cooperated, and makes well lid and well head lock solid and reliablely, guarantee that it is antitheft and do not renovate the realization of performance.Because the bottom surface is provided with reinforce belt, makes the compressive property of well lid improve greatly.

The utility model is reasonable in design, reliable operation, and have good antitheft, anti-canting and compressive property, be suitable for when water discharger for road is built and apply.

Description of drawings:

Fig. 1 is of the present utility model overlooking (end face) structural representation.Fig. 2 looks up (bottom surface) structural representation for it.

The specific embodiment:

The utility model is provided by following examples, is illustrated below in conjunction with accompanying drawing.

As shown in the figure, the utility model is made up of well lid main body 1, locking bolt 2, six wall stakes 3, reinforce belt 4, helical disk 5, its structure, assembled relation are as follows: be provided with six wall stakes 3 in the well lid main body 1 end face centre bore, be uniformly distributed with radial reinforce belt 4 on the bottom surface between the Internal and external cycle along the circumference, be provided with helical disk 5 in the inner ring, helical disk 5 tops and six pilaster 3 are one, and helical disk 5 is meshed with the helicla flute of 4 locking bolts 2 that are uniformly distributed along the circumference by 4 helical tooths on it.Wherein, the well lid main body adopts cast iron to make, and its end face is provided with centre bore, is provided with six wall stakes 3 in the centre bore, is on the bottom surface to be provided with reinforce belt 4 and locking bolt 2 taxiways radially.4 locking bolts 2 adopt round steel to make, and along circumferentially uniform, its inner is provided with the helicla flute that is meshed with helical disk 5 helical tooths.Helical disk 5 adopts cast steel to make, and vertically is provided with six wall stakes on it with it, and disk body is along circumferentially being evenly equipped with 4 helical tooths.

Claims

1, a kind of 4 iron bolt locking type catch pit well lids, form by well lid main body (1), locking bolt (2), six wall stakes (3), reinforce belt (4), helical disk (5), it is characterized in that: be provided with six wall stakes (3) in well lid main body (1) the end face centre bore, be uniformly distributed with radial reinforce belt (4) on the bottom surface between the Internal and external cycle along the circumference, be provided with helical disk (5) in the inner ring, helical disk (5) top is meshed with the helicla flute of 4 locking bolts (2) that are uniformly distributed along the circumference by 4 helical tooths on it for one helical disk (5) with six pilaster (3).
