Abstract
The utility model belongs to the technical field of municipal facilities and relates to a falling prevention well seat of a water drainage inspection well, particularly to a water drainage inspection well seat device with the safe falling prevention function. The falling prevention well seat comprises a support and a well lid, wherein the support is annular; a projecting well lid bearing platform is arranged on the inner ring of the support; a plurality of drag hooks are arranged at the bottom of the support; the well lid is placed on the well lid bearing platform of the support; the falling prevention well seat further comprises a safety net; a plurality of fixed lantern rings are arranged on the periphery of the safety net; the safety net is fixed on the drag hooks corresponding to the support through the fixed lantern rings. When the falling prevention well seat is in use, the safety net of the falling prevention well seat on the lower layer can prevent a falling object or a person from falling in the inspection well when the inspection well lid is lost or damaged, so that the safety of the inspection well is improved.
Description
Technical field
The utility model relates to the anti-fall well seat of a kind of drainage inspection well, and particularly a kind of base device of the drainage inspection well with the safe anti-falling function, belong to the urban operating mechanism technical field.
Background technology
Urban discharging pipeline lays along urban road substantially at present, for the maintenance demand, generally every tens meters, arranges a drainage inspection well.Manhole mostly is the well seat and well lid well body forms.The vehicle of overburden rolls and causes that well lid damages, and the stolen also idol of well lid has generation.The drainage pipe buried depth is darker, once the manhole well lid damages or loses, will greatly affect traffic safety and cause the person to threaten to the pedestrian.
A kind of safety anti-falling device for drainage pipeline inspection well of Chinese patent " CN201981634U ", comprise safe fall-proof net and set bolt, and the safe fall-proof net is fixed on along on the equally distributed bolt of shaft in wall.Although this device has solved the anti-fall problem of part manhole, this installs the anchoring strength that anti-fall intensity depends on pit shaft and bolt.At present drainage inspection well commonly used has steel concrete and brick two kinds of forms, so this device only solves the anti-fall problem of part reinforced concrete well, and still, for brick well, this anti-drop device just is difficult to support the intensity that the pedestrian falls well.And crab-bolt is protruded walling crib, dwindles the access path section.
Above-mentioned deficiency still has is worth improved place.
Summary of the invention
The purpose of this utility model is to provide a kind of anti-fall well seat of the drainage inspection well that anti-drop function is provided that is applicable to all drainage inspection wells.
The technical scheme provided according to the utility model, the anti-fall well seat of drainage inspection well, comprise bearing and well lid, and described bearing is annular ledge, and inner ring is provided with the well lid adapting table of a protrusion; Rest base also is provided with several drag hooks; Described well lid is positioned on the well lid adapting table of bearing;
Also comprise safety net, the safety net outer rim is provided with several retaining collars; Safety net is fixed on the drag hook that bearing is corresponding by retaining collar.
Mate mutually the quantity of described retaining collar and drag hook, shape and position.Described safety net is circular nylon wire lattice structure.The grid eyelet of described safety net is 7cm.
Described drag hook and bearing are the integral type structure.The bending part of described drag hook upwards, is evenly arranged in well lid cushion cap below along the bearing inwall.
The beneficial effects of the utility model: when the utility model is used, after the manhole well lid is lost or damaged, lower floor's anti-fall manhole well seat safety net can prevent that falling stop thing or personnel fall down manhole, improves the safety of manhole; And lifting hook device and well seat are one-body molded, anti-drop device is identical with the well seat, not limited by well body Material Strength, applicable to all GB manholes.The safety net specification is identical with well lid, and drag hook is positioned at can less maintenance section under well lid inner ring well lid cushion cap.
The accompanying drawing explanation
Fig. 1 is top view of the present utility model.
Fig. 2 is sectional view of the present utility model.
The specific embodiment
As shown in Figure 1-2, the anti-fall well seat of drainage inspection well, comprise bearing 1 and well lid 6, and described bearing (1) is annular ledge, and inner ring is provided with the well lid adapting table 3 of a protrusion; Bearing 1 bottom also is provided with several drag hooks 4; Described well lid 6 is positioned on the well lid adapting table 3 of bearing 1;
Also comprise safety net 2, safety net 2 outer rims are provided with several retaining collars 5; Safety net 2 is fixed on the drag hook 4 of bearing 1 correspondence by retaining collar 5.
Above-mentioned walling crib 1, well lid 6 are identical with existing national standard drawings with well lid cushion cap 3 structures, are not described in detail here.
Described retaining collar 5 mates mutually with quantity, shape and the position of drag hook 4.Described safety net 2 is circular nylon wire lattice structure.The grid eyelet of described safety net 2 is that 7cm is square.Described safety net 2 is similar to well lid 1 shape.
Described drag hook 4 is the integral type structure with bearing 1, can provide enough intensity to guarantee.The bending part of described drag hook 4 upwards, is evenly arranged in well lid cushion cap 3 belows along bearing 1 inwall.
The course of work of the present utility model is that safety net 2 is connected on drag hook 4 by its outer rim retaining collar 5, and when well lid is lost or damage, safety net 2 can prevent that pedestrian or vehicle from falling in manhole.When pipeline needs repair and maintenance, only the retaining collar of safety net 25 need be taken out from drag hook 4, maintenance is retightened installation after finishing and is got final product.Because drag hook 4 is positioned at well lid cushion cap 3 belows, without the evagination device, can not reduce the maintenance section.
