Description

A kind of safe, antitheft sewer ball iron manhole cover

One, technical field

The utility model relates to a kind of well lid of sewer, especially a kind of safe, antitheft sewer ball iron manhole cover.

Two, background technology

At present, domestic well cover for sewer used, does not generally establish locking device, can only cover well head, and exist and easily by people, stolen, or because sewer raise of stage recharges the defect of well lid being gone out to well head, and cause unsafe accident to happen occasionally.The utility model, on the basis of former well lid, is considered well lid using area, determines the compressive strength of well lid by using area, is guaranteeing that pressure meets under the prerequisite of country (world) standard, has set up three locking devices between well lid and walling crib.When sewer raise of stage, because well lid locks, can well lid not gone out because sewer raise of stage recharges, well lid firmly covers well head all the time.Be provided with twice anti-theft device simultaneously, as there is no special tool and professional technique, common people cannot open well lid, thereby have guaranteed the safety of pedestrian and driving.Thus, develop a kind of safe, antitheft sewer ball iron manhole cover, there is good development and application values and good social benefit.

Three, utility model content

The purpose of this utility model is: provide a kind of pressure to meet national requirements, security performance is high, good anti-theft effect, and car presses people to step on tight sewer ball iron manhole cover.

For achieving the above object, the technical solution of the utility model is: a kind of safe, antitheft sewer ball iron manhole cover, is comprised of well lid, walling crib, magnetic control theftproof lock, alignment pin theftproof lock; It is characterized in that: in the top of walling crib, be provided with 3 " 7 " type Manhole cover lock keyholes,, on the relevant position between walling crib and well lid, being provided with 1 magnetic control theftproof lock and 1 alignment pin theftproof lock, well lid (1) edge is equipped with 3 Manhole cover lock bolts.

Described magnetic control theftproof lock is by locking bolt Z, locking bolt latch Y, and closed lockhole plug X forms, and locking bolt Z is the large cylinder in little two, a centre, and top is provided with pin hole.

Described alignment pin theftproof lock, is between walling crib and well lid, to open a dowel hole, and pin is squeezed into this dowel hole, and pin upper end is equipped with triangle nut, uses common spanner and sleeve can not pull triangle nut.

On the symmetrical position of well lid, be provided with two well lid open holes, and have well lid special opening spanner.

The mounting method that this practicality is new: when well lid is installed, first walling crib is fixed with C15 mono-C20 concrete, then three locking bolts on well lid edge are aimed to three of walling crib tops and put into walling crib after " 7 " type lock hole, the rotation of then turning right, is stuck in walling crib locking bolt.Now location pin is squeezed in pin-and-hole, the pin pin nut of reaching the last should be screwed onto pin screw topmost, flushes with screw upper end.In order to strengthen anti-theft feature, on the parallel diagonal angle of alignment pin, establish a magnetic control lock, the mounting method of this lock, before well lid is installed, locking bolt exceeds well lid surface, with a latch, pin is fixed on well lid.When alignment pin is squeezed into dowel hole, pull up latch, now magnetic control locking bolt falls into locking in pin-and-hole automatically.

Open method of the present utility model and operating principle: (1) is pressed magnetic control lock open method by magnetic control lock and opened, and removes the locking of well lid and walling crib; First open lockhole plug; The magnet steel that one diameter is more smaller than magnetic control lockhole is put into lockhole, and now locking bolt is held by magnet steel, with handgrip magnet steel, up carries to locking bolt pin hole, latch can be inserted to pin hole.Now locking bolt has departed from well lid base plate pin-and-hole, and magnetic control lock lost efficacy.(2) with special spanner (the special spanner of triangle), the triangle nut clockwise direction of alignment pin is down tightened, now shop bolt is pulled up, can be by taking out positioning pin after becoming flexible, and alignment pin locking device is disengaged.(3) with special spanner, two parallel fill-in wells of plug on spanner are covered in two open holes, counterclockwise firmly, when now on well lid, three locking column bolts are turned left to walling crib straight hole along walling crib lock slots, Manhole cover lock is removed completely.Then two hooks are put into well lid driving hole, up lift well lid and be opened, being put in certain distance outside walling crib does not affect construction safety.

The beneficial effects of the utility model: (1) this well lid because having added three locking devices between well lid and walling crib.When there is vehicle on well lid surface, roll, pedestrian is when walk, well lid is blocked, well lid does not have loosening, does not just have sound yet, more can not overturn; (2) when sewer raise of stage, because well lid locks, can well lid not washed open because sewer raise of stage recharges, well lid firmly covers toward well head all the time.Thereby guaranteed driving vehicle and pedestrian's safety, no longer recurred this year Changsha maiden and fall into the tragedy of sewer; (3) except well lid and walling crib have locking bolt device, in order to prevent artificial destruction or theft.Antitheft alignment pin and magnetic control lock double anti-theft device between well lid and walling crib, have been increased.Guaranteed that well lid can not stolen easily by people; 4) cost is low, is easy to processing and installs.
