Description

A kind of portable lever type manhole cover opening device

Technical field

The utility model relates to a kind of portable well cover opening device, and it belongs to well lid opening device class.

Background technology

the urban water supply and sewerage underfloor duct is the requisite urban operating mechanism in any one city, general plumbing underfloor duct all can arrange a vertical shaft every certain distance, so that the staff clears up and safeguards the plumbing underfloor duct by vertical shaft, described vertical shaft generally all uses the well lid of a circle or square cast iron to cover, in city, such well lid is found everywhere, when the municipal administration staff safeguards vertical shaft, at first must open these well lids, in the prior art, it is ripping bar that the municipal administration staff opens well lid instrument the most commonly used, during work, ripping bar is inserted along the well lid edge, utilize the principle of lever that well lid is levered up, the problem that prior art exists is, existing its well head of many vertical shafts all is provided with a crib, form the cavity of an accommodating well lid on described crib, described well lid is placed in this cavity of institute, lifting along with the manufacturing process technology, gap between existing well lid and crib is very little, although traditional ripping bar is easy to carry, operation is also convenient, but in the face of the very little situation in the gap between this well lid and crib, usually seem helpless, usually cause for it reluctantly the damage of crib or well lid, obviously prior art has further improved necessity.

Summary of the invention

The purpose of this utility model is to provide a kind of portable lever type manhole cover opening device, the problem that exists to solve prior art.

A kind of portable lever type manhole cover opening device of the present utility model, comprise ripping bar, characterized by further comprising a bearing and a hinge bar, described hinge bar is fixed on described ripping bar, connect position as boundary take connecting firmly of described hinge bar and ripping bar, described ripping bar is divided into power arm and resistance arm, and described ripping bar is articulated on described bearing by the hinge bar affixed with it and rotating shaft, and the termination first line of a couplet of described resistance arm is connected to drag hook.

This portable lever type manhole cover opening device of the present utility model, as long as make during use drag hook hook open hole on well lid, then apply pressure to power arm, under the effect of lever, can very like a cork well lid be mentioned, and the purpose of this utility model obviously is achieved.

As further improvement, described power arm end is built-in with telescopic bar, ought meet like this because the reasons such as corrosion cause the combination of well lid and crib very firm, while being difficult for opening, extension rod can be pulled out, to lengthen the length of power arm.

As further improving, described bearing comprises chassis, at least be provided with two pipe connection seats on described chassis, described two pipe connection seats connect firmly and are connected on described chassis, and a horizontally set, and one vertically arranges, the additional pole that also comprises three pipe reducers, the microcephaly of additional pole can be inserted in connection seat and the major part of additional pole in, wherein two additional poles are plugged in respectively the pipe connection seat two ends of horizontally set, the additional pole of another root is plugged on the pipe connection seat of vertical setting; Can promote the stability of seat supports like this;

Further improvement as aforementioned improved, be provided with additional pole fixed support on described ripping bar, like this, when not using after three additional poles can being taken off and be socketed into a pipe, be fixed on additional pole fixed support, be easy to carry so on the one hand, can prevent the addition rod loss simultaneously.

As further improving, described bearing offers the through hole suitable with the ripping bar external diameter, and described bearing is sleeved on described ripping bar by described through hole, bearing can be pulled down when not using like this, and be sleeved on ripping bar, convenient for collecting and carrying.
