Description
Technical field：
The utility model is related to a kind of manhole with horizonal hanging cover devices.
Background technology：
Common part of the manhole device as container class product, be equipment installation, internal overhaul important supplementary structure, people
Hole opening structure is various informative, there is arm hanging type, hinge type and some quick-opening structures, for vertically disposed manhole device, this
A little structures meet design requirement, and horizontally disposed manhole device may be needed using hinge type or arm hanging type structure when opening
Manually lift blind flange, thereby increases and it is possible to sealing surface is damaged, it is inconvenient and hidden in the presence of safety when especially manhole cover quality is larger
Suffer from.
Utility model content：
The purpose of this utility model is to solve horizontally disposed manhole device to lift difficulty, it is inconvenient the problems such as, provide
A kind of safe operation, easily manhole with horizonal hanging cover device.
Above-mentioned purpose is realized by following technical scheme：
A kind of manhole with horizonal hanging cover device, composition include：Pivoted arm, manhole cover have connecting hole, institute on the pivoted arm
There is internal thread in the connecting hole stated, pedestal is installed on the manhole cover, on the pedestal there is circular groove, lift lever to wear
It crosses the connecting hole to be threadedly coupled with the connecting hole, the lower end of the lift lever has a circle groove, two cover boards
It is buckled in the both ends of the groove respectively, the cover board is fixedly connected with the pedestal, the upper end tool of the lift lever
There are square toes, rotating handle to be sleeved on the square toes of the lift lever, the rotating handle is fixed with the lift lever by locking nut
Connection.
The manhole with horizonal hanging cover device, the cover board semicircular in shape, the height of the cover board is less than described
The height of groove, the groove lower end are less than the height of the circular groove at a distance from the bottom end of the lift lever.
Advantageous effect：
1. the operation principle of the utility model is：When unlatching, by rotating rotating handle, lift lever rotates, under threaded function,
Manhole cover gets a promotion, and is promoted to after object height, is moved away manhole cover by pivoted arm, when closing, by pivoted arm by manhole cover
Go to target location, rotation rotating handle slowly puts down manhole cover, and rotating handle resistance obviously becomes hour and shows that manhole cover has been placed into most
Low spot after installing, removes rotating handle and is preserved by relevant person in charge, with take precautions against accidentally touch, non-permitted personnel operation etc..
Provided by the utility model is a kind of manhole with horizonal hanging cover device, is combined with pivoted arm using rotating handle, lift lever, will
Power needed for operation greatly reduces, to when horizontally disposed manhole device opens and closes so that and manual operation is convenient, safe, and
Damage sealing surface is can avoid, is realized with smaller operating force, is completed the unlatching of big quality manhole cover, solve horizontally disposed people
Pore structure opens the problems such as difficult, operation is dangerous.
The height of the cover board of the utility model is less than the height of groove, and groove lower end is less than at a distance from the bottom end of lift lever
Circular groove height, the design in the two gaps can to determine that rotation off-position is set when closed, meet humanization designing, behaviour
Make facilitation.

Specific implementation mode：
Embodiment 1：
A kind of manhole with horizonal hanging cover device, composition include：Pivoted arm 3, manhole cover 7 have connecting hole on the pivoted arm
8, the connecting hole is interior to have internal thread, and pedestal 6 is equipped on the manhole cover, has circular groove 9 on the pedestal, carries
Rising stem 4 is threadedly coupled across the connecting hole with the connecting hole, and the lower end of the lift lever has a circle groove 10,
Two cover boards 5 are buckled in the both ends of the groove respectively, and the cover board is fixedly connected with the pedestal, the lift lever
Upper end there are square toes 11, rotating handle 2 to be sleeved on the square toes of the lift lever, the rotating handle passes through lock with the lift lever
Tight nut 1 is fixedly connected.
Embodiment 2：
According to manhole with horizonal hanging cover device described in embodiment 1, the cover board semicircular in shape, the height of the cover board
Less than the height of the groove, the groove lower end is at a distance from the bottom end of the lift lever less than the circular groove
Highly.
