Abstract

The invention relates to an anti-theft well cover, comprising an upper well cover, a lower well cover, a connecting rotation axis and a plurality of well ties; the well ties are fixed on the well wall; the lower well cover is provided with a plurality of breaches; the quantity and the positions of the breaches are corresponding to the well ties; the dimension of the breach is slightly more than that of the exposal part of the well ties; the upper well cover is connected with the lower well cover by the connecting rotation axis; the connecting rotation axis comprises a rotation connecting rebar, a sleeve and a fixed rebar, wherein, the lower end of the rotation connecting rebar is fixed on the lower well cover; the upper part of the rotation connecting rebar is arranged into the sleeve by an upper nut and a lower nut; the sleeve is fixed on the upper well cover by the fixed rebar; the upper well cover is provided with a central hole which is arranged on the same longitudinal axial line with the rotation connecting rebar. The anti-theft well cover of the invention is locked by the ties of the well cover, can prevent the lock rusting in the prior art, and has the advantages of strong anti-theft function, simple structure, convenient opening and low manufacture cost.

Description

A kind of anti-stealing manhole cover

One, technical field

The present invention relates to a kind of stolen well lid of facility in the well that is used to prevent.

Two, background technology

The city manhole cover incident of hurting sb.'s feelings stolen, that lose, damage and cause thus happens occasionally, and this type of problem has become " common fault " of National urban.Well lid is lost becomes the bigger potential safety hazard of urban development.This no doubt has legal issues such as communication and education, but reflects the shortage of well lid safety measure more.The traditional well lid of China is generally cast iron and makes, and according to the difference of carrying, is divided into heavy and light-duty two kinds, plays effects such as protection.In case but well lid is stolen, often just runs counter to desire.In recent years, domestic some antitheft well lids that occurred as electromagnetism combination type, mechanical type etc., but in actual applications, are not very extensive, reason mainly show as cost higher, install complicated, corrosion is not durable etc. easily.Therefore, invention has the anti-stealing manhole cover of characteristics such as unlatching is convenient, and installation is simple, and cost is low, has certain realistic meaning.

Three, summary of the invention

The present invention proposes the well lid that a kind of energy manufacture craft is simple, theftproof performance is stronger according to the characteristics of well lid.Anti-stealing manhole cover of the present invention generally is applicable to less pit shaft (hole diameter is less than 400mm).

A kind of anti-stealing manhole cover, comprise well lid, down well lid, connect turning cylinder and some wells are stumbled, wherein, well is stumbled and is fixed on the borehole wall, goes into the well to cover some gap are set, it is corresponding that the quantity of gap and position and well are stumbled, the size of gap is slightly larger than the exposed parts that well is stumbled; Last well lid connects well lid down by connecting turning cylinder; Described connection turning cylinder comprises the reinforcing bar that is rotationally connected, sleeve pipe and fixing reinforcing bar, wherein, the be rotationally connected lower end of reinforcing bar is fixed on to go into the well and covers, and the top of the reinforcing bar that is rotationally connected is installed in the sleeve pipe by upper and lower two nuts, and sleeve pipe is fixed on the well lid by fixing reinforcing bar; Last well lid is provided with centre bore, centre bore be rotationally connected reinforcing bar on same longitudinal axis.

Further, the vertical distance between following well lid and well are stumbled is 0.5～10cm.

Further, the well quantity of stumbling is 4～6.

Further, the upper end head of the described reinforcing bar that is rotationally connected is processed into irregularly shaped and adapts with the sleeve-shaped of key.

Anti-stealing manhole cover of the present invention is stumbled by the well lid card and to be locked, and can prevent the corrosion problem of in the past locking, and has stronger anti-theft feature again, and is simple in structure, and it is convenient, cheap to open.

Fig. 4 connects the turning cylinder detail

Among the figure, 1 stumbles for well, well lid on 2, and 3 are well lid down, and 4 for connecting turning cylinder, and 5 be key, and 6 for being rotationally connected reinforcing bar, and 7 is sleeve pipe, and 8 is fixing reinforcing bar, and 9 is nut, 10 is centre bore.

Five, the specific embodiment

Anti-stealing manhole cover of the present invention by well stumble 1, go up well lid 2, well lid 3 and be connected turning cylinder 4 four parts and form down.

Well is stumbled and 1 is fixed on the borehole wall, and 4～6 of operated by rotary motion, around walling crib, are an angle of 90 degrees, overhead certain distance by preferred 4.Be used to prevent that well lid from illegally opening.But key operated behind certain angle when well lid, well lid just can be opened.

Well lid is made up of last well lid 2 and following well lid 3, is cut with on the following well lid 3 and stumble 1 the identical gap of quantity of well, and gap is descending stumble 1 position of position and well on the well lid 3 corresponding, and the gap size is slightly larger than stumble 1 exposed parts of well.Instantly the gap of well lid 3 rotates to well 1 position of stumbling, and well lid can be mentioned and opened.Last well lid 2 is provided with centre bore, is convenient to key and inserts and to rotarily open, and also can be used as simultaneously to mention origin of force and upwards open.Following well lid 3 blocks well and stumbles 1 the effect except having, and around can also being distributed to the rainwater that the top layer flows to, along borehole wall landing, prevents that rainwater from directly falling, and hits and spatters facility in the well, causes unnecessary destruction; Dust is directly fallen in the well above can also preventing in addition.The vertical interval that following well lid 3 and well are stumbled between 1 is less, is generally 0.5～10cm, to prevent other people last well lid 2 perks, between last well lid 2 and walling crib slit, destroys well lid.Well lid can adopt steel plate or grey plastic plate or composite material to make according to load bearing requirements.

Upper and lower well lid connects by connecting turning cylinder 4, connects turning cylinder 4 and comprises the reinforcing bar 6 that is rotationally connected, sleeve pipe 7 and fixing reinforcing bar 8.The be rotationally connected lower end of reinforcing bar 6 is weldingly fixed on down on the well lid 3, and the top is fixed in the sleeve pipe 7 by upper and lower two nuts 9, and it can only be rotated, and can not be up and down; And sleeve pipe 7 is weldingly fixed on the well lid 2 by fixing reinforcing bar 8, and upper and lower well lid is connected as a single entity, and during well lid 3 rotations so instantly, last well lid 2 can keep static, when needs are opened, when opening time well lid, opens well lid.The upper end head of the described reinforcing bar 6 that is rotationally connected must mill with the key sleeve adapt irregularly shaped, and the bottom of the upper end head of the described reinforcing bar 6 that is rotationally connected and last well lid 3 should keep certain distance, prevents that other instruments from entering.

The drive a well similar box spanner of key 5 practical functions of lid can be according to the field machining situation, and what the sleeve section was processed into and the upper end head of the reinforcing bar 6 that is rotationally connected adapts is irregularly shaped, prevents that further him from opening by the human common tool.

When normal unlatching, key 5 is entangled connection turning cylinder 4, rotate to an angle, make down well lid 3 break away from wells and stumble 1, upwards mention, can open; When locking, will descend well lid 3 gap to aim at well and stumble and 1 put into, and, well be stumbled 1 block down well lid 3, and upwards try to carry,, promptly pin as not opening then with key 5 rotations.
