Abstract
The invention discloses a manhole cover opening device which comprises a crowbar, a suction cup, a supporting plate, a movable wheel and a drive mechanism. The front end of the crowbar is connected with the suction cup, the lower portion of the suction cup is provided with an electromagnet attractive to the suction cup, the tail end of the crowbar is connected with the supporting plate, the movable wheel is arranged on the lower portion of the supporting plate, and the drive mechanism is arranged above the supporting plate. The electromagnet disposed at the front end of the crowbar is matched with the suction cup, so that manhole cover damage caused by opening of a manhole cover is reduced. By means of the lever principle and the drive mechanism, the manhole cover is easy to open, time and labor are saved, and the manhole cover can be easily dragged after being lifted by means of the additional arrangement of a universal wheel. Besides, a manual pressing rod is arranged, workers can select whether to open the manhole cover through the drive mechanism or manually, various opening modes are provided, and the manhole cover opening device is convenient to use, practical and suitable for various manhole cover opening occasions. The manhole cover opening device effectively solves the technical problems that in the prior art, damage is prone to being generated during manhole cover opening, labor and time are wasted during manhole cover opening, and the manhole cover is difficult to move after being lifted.
Description
Technical field
The invention belongs to inspection well kit technical field, be specifically related to a kind of well cover opening device.
Background technology
Well lid, is arranged on openable 4 that can to lead to top, gangway, the surface of underground installation inspection well be plane, is the main auxiliary products of inspection well.The place of the subsurface utilities such as every installation tap water, telecommunications, electric power, combustion gas, heating power, fire-fighting and environmental sanitation all needs installation check well and the well lid supporting with it.
Well lid mainly can load-bearing, sealing and unlatching inspection well, so that general-utility service personnel passes through open manhole cover, inspection well underground utilities and facility are checked, cleaning dirt, inspection and maintenance, the personnel that prevention is passed by drop in inspection well, can bear the large flow of vehicular traffic and maximum speed travels, guarantee the coast is clear and safety traffic, also can prevent that foreign matter from falling in inspection well, ensure that underground utilities and facility normally move.
Well lid of the prior art, mainly be divided into metal well lid and nonmetal manhole cover, metal well lid bearing capacity is high, shock resistance fatigue resistance is good, but cost is high, anti-theft is poor, nonmetal manhole cover cost is low, anti-theft is high, but weight is large, poor, the easy breakage of shock resistance fatigue resistance, the life-span is short, unlatching is inconvenient.How to develop a kind of well cover opening device time saving and energy saving, easily and effectively and become new problem.
Summary of the invention
Technical matters to be solved by this invention is just to provide a kind of well cover opening device, at crowfoot front end, electromagnet is set and sucker cooperatively interacts, damage to well lid while reducing open manhole cover, utilize lever principle and driver train, make the unlatching of well lid simple, time saving and energy saving, install cardan wheel additional and well lid is lifted easily drag afterwards.In addition, be also provided with Manual pressure bar, staff can select the automatic open manhole cover of driver train or manually opened well lid, and multiple opening ways is provided, convenient and practical, more can adapt to various well lid and open occasion.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of well cover opening device, comprise crowbar, sucker, supporting disk, movable pulley and driver train, described crowbar front end is connected with sucker, described sucker below is provided with the electromagnet of inhaling mutually with it, described crowbar end is connected with supporting disk, and described movable pulley is located at supporting disk below, and described driver train is located at supporting disk top.Electromagnet and sucker cooperatively interact, and well lid are opened to the damage to well lid while reducing open manhole cover.
Preferably, described supporting disk top is also provided with Manual pressure bar, and described Manual pressure bar is fixedly connected with crowbar end.Staff can select the automatic open manhole cover of driver train or manually opened well lid, and multiple opening ways is provided, convenient and practical, more can adapt to various well lid and open occasion.
Preferably, described movable pulley is universal wheel component, and described universal wheel component comprises cardan wheel and the Universal castor being mated.Can make well lid lift easily drags afterwards.
Preferably, described Universal castor is provided with at least two cardan wheels.
Preferably, described driver train is gas piston cylinder or hydraulic cylinder.Make the unlatching of well lid simple, time saving and energy saving.
The invention discloses a kind of well cover opening device, at crowfoot front end, electromagnet is set and sucker cooperatively interacts, damage to well lid while reducing open manhole cover, utilize lever principle and driver train, make the unlatching of well lid simple, time saving and energy saving, install cardan wheel additional and well lid is lifted easily drag afterwards.In addition, be also provided with Manual pressure bar, staff can select the automatic open manhole cover of driver train or manually opened well lid, and multiple opening ways is provided, convenient and practical, more can adapt to various well lid and open occasion.Efficiently solve open manhole cover in prior art and easily cause damage, well lid unlatching effort is time-consuming to be lifted and is difficult to mobile technical matters with well lid.
