Abstract
The invention provides a kind of well cover opening device, including a lever, one tripod, lever mounting blocks are provided with the top of the tripod, lever mounting blocks are hinged with lever, and lever can be rotated upwardly and downwardly around pin joint, and lever is divided into major axis and short axle by pin joint, the afterbody of short axle is connected with least two chains, and the low side of each chain is provided with a hook.The present invention utilizes lever principle, using the pin joint of lever mounting blocks and lever as fulcrum, is lifted well lid by the short axle of lever, not only time saving and energy saving, but also the unlatching for reducing well lid is damaged.The present invention can avoid injury of the employee in regular job, ensure that employee injures beyond not causing at work.
Description
Technical field
The invention belongs to field of engineering technology, more particularly to a kind of well cover opening device.
Background technology
The pipeline such as development and needs, conventional running water, telecommunications, electric power, combustion gas, heating power, fire-fighting with urban construction
Or cable is routed to underground, and the pit shaft for maintenance and repair, well room are arranged at intervals along the line, in the top of pit shaft and road
Flush place installation can open manhole cover, relevant facility is safeguarded into well room by well lid in routine use.
At present, common well lid opening ways are, it is necessary to use two kinds of instruments of pick and crowbar, first by pick insertion well lid unlatching
In hole, after well lid opens certain gap, by crowbar inserted into gap, prevent well lid from injuring unlatching personnel by a crashing object, then open well lid
Open.In open manhole cover, one can not operate the instrument of the use, time and effort consuming；Security is poor, the tip and well of pick
It can not fix in the opening process of lid, easily hurt sb.'s feelings.
The content of the invention
It is an object of the invention to provide a kind of well cover opening device, to solve safety existing for existing well cover opening device
The problem of property is poor, laborious.
To achieve the above object, the present invention uses following technical scheme：
A kind of well cover opening device, including a lever, a tripod, lever peace is provided with the top of the tripod
Block is filled, lever mounting blocks are hinged with lever, and lever can rotate upwardly and downwardly around pin joint, and lever is divided into major axis and short by pin joint
Axle, the afterbody of short axle are connected with least two chains, and the low side of each chain is provided with a hook.
The hook includes the fixing end being connected with chain, and the movable end being hinged with fixing end, the bottom of fixing end
It is provided with limited block.
The material of the chain is stainless steel.
The end set of the major axis has wavy bulge.
The length of the major axis and short axle ratio is 6:4~7:3.
Beneficial effect：The present invention utilizes lever principle, using the pin joint of lever mounting blocks and lever as fulcrum, passes through lever
Short axle well lid is lifted, it is not only time saving and energy saving, but also the unlatching for reducing well lid is damaged.The present invention can avoid employee in day
Often injury during operation, it ensure that employee injures beyond not causing at work.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structural representation of hook.
Embodiment
Further explanation is done to the present invention with reference to embodiment.
As shown in figure 1, a kind of well cover opening device, including a lever, a tripod 3, the top of the tripod 3
Lever mounting blocks 4 are provided with, lever mounting blocks 4 are hinged with lever, and lever can rotate upwardly and downwardly around pin joint, and pin joint is by thick stick
Bar is divided into major axis 1 and short axle 2, and the afterbody of short axle 2 is connected with two chains 5, and the low side of each chain 5 is provided with a hook 6.
As shown in Fig. 2 hook 6 includes the fixing end 61 being connected with chain 5, and the movable end being hinged with fixing end 61
62, the bottom of fixing end 61 is provided with limited block 63, for movable end 62 is spacing, makes between fixing end 61 and movable end 62
Angle is between 0-90 °.Before use, movable end 62 can be upwards collected through, so reduces the volume of hook 6, be easy to stretch into well lid
Hole in.
The material of chain 5 is stainless steel.
The end set of major axis 1 has wavy bulge 7, plays anti-skidding effect.
The length of major axis 1 and short axle 2 ratio is 6:4~7:3.
In use, first movable end 62 will be upwards collected through, so reduce the volume of hook 6, be easy to stretch into the hole of well lid
In, hook 6 stretches into the Kong Zhonghou of well lid, and movable end 62 is freely fallen, and is in 90 ° with fixing end 61, and spacing by limited block 63,
Two hooks 6 are respectively protruding into two holes of well lid, are lifted up, after ensureing that hook can be stuck in well lid, by major axis
End is depressed, and using the pin joint of lever mounting blocks 4 and lever as fulcrum, is lifted well lid by the short axle of lever, not only time saving
It is laborsaving, but also the unlatching for reducing well lid is damaged.
Described above is only the preferred embodiment of the present invention, it should be pointed out that：For the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
