Description

Mechanical reinforced anti-theft safety well cover

Technical Field

The invention relates to a mechanical reinforced anti-theft safety well cover, which adopts a mechanical adjustable reinforcing device, can lock the well cover to prevent theft, increase the bearing capacity of the wall surface of a well, prevent the road surface from being damaged, increase the stress area of the well cover, and ensure that the well cover has the characteristics of uniform stress, difficult damage and the like.

Background

At present traditional well lid is direct to be covered on well body mouth, because the stress that the well lid bore is concentrated relatively, damaged phenomenon often appears in the well lid, simultaneously, under the exogenic action, the stress that transmits the peripheral asphalt concrete of well body by the well lid is also concentrated relatively, and the peripheral road of well lid produces radial crack and pit, cracked, sinks easily, and these diseases have destroyed road surface structure, have reduced the life of road. In addition, most well covers are made of iron products, have high secondary use value, are easy to steal, and pose serious threats to the safety problems of pedestrians and vehicles.

The invention patent with the patent number of 108331028A discloses an intelligent well lid, which is provided with an intelligent monitoring device and can automatically detect whether the well lid is damaged or lost. The invention has complex structure, easy damage and high maintenance and repair cost, needs professional technical personnel to operate, has complex operation and is difficult to realize mass production. Secondly, the well lid does not fundamentally solve the defects that the traditional well lid has small bearing capacity and is easy to damage, and needs external extra power supply, and the well lid is mainly used outdoors, is relatively dispersed, is not easy to meet the requirement of power supply, and needs to consume a large amount of electric energy, so the well lid is not practical enough. The mechanical reinforced anti-theft safety well lid provided by the invention adopts mechanical pressurization, is easy to realize, has small technical difficulty, is easy to maintain, has large production benefit, and has obvious advantages compared with an intelligent well lid.

Disclosure of Invention

(1) Technical problem to be solved

The invention aims to solve the technical problems that the mechanical reinforced anti-theft safety well lid is arranged, the pressure and impact bearing capacity of the well wall is improved, the safety problems of driving and pedestrians caused by cracks and subsidence of the road surface around the well and easy damage of stress concentration of the traditional well lid are prevented, and the possibility of well lid theft is reduced by pressurizing and locking the well lid through a mechanical reinforcing device.

(2) Technical scheme

The mechanical reinforced anti-theft safety well cover consists of cover body, spiral mechanical pressurizing unit, lock hole type rocker hole and rocker. The cover body is basically the same as the traditional well cover, the size of the well cover is manufactured according to the standard of a well hole, a spiral mechanical pressurizing device is additionally arranged on the bottom surface of the well cover, a lock hole type rocker hole is formed in the middle of the well cover and is connected with the spiral mechanical pressurizing device, and a specific external rocker can be matched and connected with the lock hole type rocker hole.

After the anti-theft safety well lid is consolidated to installation mechanical type, connect the rocker and be connected with lockhole formula rocker hole, through rocking the rocker, flexible arm shrink, the clutch blocks is fixed on the wall of a well, and the well lid is fixed to be locked this moment, prevents to be stolen.

Because the telescopic wall contracts, the acting force vertical to the well wall generates strong pressure on the well wall, external pressure born by a part of well wall is offset, so that the capability of the well wall for bearing transverse pressure is increased, cracks are not easy to appear, and the possibility of damage is reduced.

Through the shrink of flexible arm, make well lid center share the bearing capacity at well lid edge, make the well lid atress even, the relative well body is fixed, increases well lid resistance to compression, shock resistance, prevents that the well lid is damaged.

(3) Advantageous effects

With the rapid development of economy in China, infrastructure must be advanced, and the well lid plays an important role as a closure of the top of an access opening leading to underground facilities (such as tap water, a heat distribution pipeline, electric power and the like), but the condition that the well lid is crushed and damaged sometimes happens, so that the safety of road facilities is reduced.

The reinforced anti-theft mechanical safety well lid can increase the pressure and impact bearing capacity of the well wall, prevent the pavement around the well from cracking and sinking, avoid the problem that the well lid is easy to damage due to stress concentration, increase the service life of roads, well mouths and well lids, and reduce the extra maintenance and repair cost; reduce because pedestrian, the driving safety problem that the well lid damage, well head subsided and brought to and through the dead well lid of mechanical type reinforcing apparatus pressurization lock, reduce the stolen possibility of well lid. Therefore, the invention has great social benefit.

Detailed Description

The mechanical reinforced anti-theft safety well cover consists of a cover body 4, a spiral mechanical pressurizing device 12, a lock hole type rocker matching hole 11 and a rocker 2. The cover body 4 is basically the same as the traditional well cover, and the size of the well cover is manufactured according to the standard of a well hole; spiral mechanical type pressure device 12 installs additional on the well lid bottom surface, leaves lockhole formula rocker mating holes 11 in the middle of the lid 4 and links to each other with spiral mechanical type pressure device 12, can drive rocker 2 through rotating rocking handle 1 and rotate, and specific rocker cooperation shaft section 3 can cooperate with lockhole formula rocker mating holes 11 and be connected, can drive bolt 7 along with the rotation of rocker 2 and rotate, and bolt 7 and bearing 5 cooperate, and the bolt rotates upwards to promote screw hole 8, and then makes telescopic boom 9 shrink.

After the anti-theft safety well lid is reinforced to installation mechanical type, connect rocker 2 and lockhole formula rocker mating holes 11 and be connected, through rotating rocking handle 1, revolute pair 10 rotates, drives flexible arm 9 shrink, and clutch blocks 6 fixes on the wall of a well, and lid 4 is fixed the lock at this moment and is died, prevents stolen.

Because the telescopic arm 9 contracts, the acting force vertical to the well body 13 generates strong pressure on the well wall, and external pressure born by a part of the well wall is offset, so that the capability of bearing transverse pressure by the well wall is increased, cracks are not easy to appear, and the possibility of damage is reduced.

Expand through flexible arm 9, make the bearing capacity at lid 4 edge shared around the well lid center, make lid 4 atress even, avoid stress concentration phenomenon, increase lid 4 resistance to compression, shock resistance, prevent that lid 4 from being destroyed.

When the well lid is disassembled, the rocker handle 1 is rotated in the opposite direction, the telescopic wall arm 9 is unfolded, the well lid can be freely moved at the moment, and the maintenance and inspection operation of pipelines and pipelines inside the well is carried out.
