Description

Manhole catching device

One, technical field:

The utility model relates to manhole supplementing facility equipment, what be specifically related to is manhole catching device.

Two, background technology:

Manhole is the maintenance such as power supply, feedwater, draining, communication, cable television, gas pipe, public lighting circuit for Urban Underground infrastructure, easy for installation and arrange.Generally being located on pipeline intersection, turning, caliber or gradient change place and straight line pipeline section and locating at a certain distance, is be convenient to make regular check on ancillary structure.In order to safety, install anti-drop net in some manholes, existing anti-drop net is circular, has grid, anti-drop net needs to be arranged in manhole with swollen nail, but after manhole uses for a long time, there is problem of aging in the borehole wall, firm not, therefore swollen nail may produce loosening, anti-drop net just can not be securely fixed, and because the connection of anti-drop net and the borehole wall is firm not, makes anti-drop net in use there is potential safety hazard.In addition, in manhole, play swollen nail when anti-drop net is installed construct dangerous, and operation is very difficult.

Three, summary of the invention:

The purpose of this utility model is to provide manhole catching device, and this manhole catching device exists the problem of potential safety hazard in the use procedure of existing manhole anti-drop net for solving.

The utility model solves the technical scheme that its technical problem adopts: this manhole catching device is integrally made up of support ring and anti-fall basket, and the inward flange of support ring is provided with the connector of tubular, and connector and support ring are mutually vertical; Anti-fall basket is cylindric, and the netful lattice of basket base fabric of anti-fall basket, the basket wall of anti-fall basket is also covered with grid, and the basket wall upper port of anti-fall basket and the connector of support ring weld together.

A kind of manhole catching device is made up of support ring and nylon anti-drop net, and the inward flange of support ring is provided with the connector of tubular, and connector and support ring are mutually vertical, and the lower limb of connector is provided with little ring, and nylon anti-drop net hangs on little ring.

Beneficial effect:

1, when the utility model uses, support ring is directly sitting on the step of well lid bearing of manhole, and the width of support ring matches with the step width of well lid bearing, anti-fall basket is supported, easy for installation, open well lid, support ring is placed on step, there is not the problem of installing difficulty.

2, in the utility model use procedure, even if the well lid of manhole is damaged, because anti-fall basket is sunk type, also by less than damage, anti-fall basket can be prevented to be damaged because well lid damages, use safety.

3, the utility model is changed easily, if anti-fall basket is damaged, opens well lid, is taken out by the utility model, then place one new.

4, the utility model in use, even if well lid bearing has slight crack or distortion, because support ring is sitting on the step of well lid bearing, also still can use safely.

Four, accompanying drawing illustrates:

Fig. 1 is structural representation of the present utility model;

Fig. 2 is top view of the present utility model;

Fig. 3 is the lateral view of support ring in the utility model;

Fig. 4 is the structural representation of the another kind of embodiment of the utility model.

1. little ring 5. anti-drop net of support ring 2. anti-fall basket 3. connector 4..

Five, detailed description of the invention:

Below in conjunction with accompanying drawing, the utility model is described further:

Shown in composition graphs 1, Fig. 2, this manhole catching device is integrally made up of support ring 1 and anti-fall basket 2, consults Fig. 3, and the inward flange of support ring 1 is provided with the connector 3 of tubular, and connector 3 is mutually vertical with support ring 1.Anti-fall basket 2 is cylindric, the netful lattice of basket base fabric of anti-fall basket 2, the basket wall of anti-fall basket 2 is also covered with grid, water freely can pass through grid, the basket wall upper port of anti-fall basket 2 and the connector 3 of support ring 1 are welded to connect, and the upper port diameter of anti-fall basket 2 is suitable with the diameter of support ring connector 3, after anti-fall basket 2 welds with connector 3, support ring 1 is protruding from the upper port of anti-fall basket 2, forms the outside eaves of anti-fall basket 2.

When the utility model uses, after anti-fall basket 2 passes from the step of the well lid bearing of manhole, support ring 1 is sitting on the step of well lid bearing, the width of support ring 1 is suitable with the step width of well lid bearing, support ring 1 relies on and self is sitting on step with the gravity of anti-fall basket 2, the basket wall of anti-fall basket 2 is just by step, and installation and use is all very safe.

As shown in Figure 4, the another kind of manhole catching device that the utility model provides is made up of support ring 1 and nylon anti-drop net 5, the inward flange of support ring 1 is provided with the connector 3 of tubular, connector 3 is mutually vertical with support 1 ring, the lower limb of connector 3 is provided with eight little rings 4, eight little rings 4 are uniformly distributed along connector 3 lower limb, and nylon anti-drop net 5 hangs on little ring 4.
