Description
Technical field
This utility model relates to Well cover unlatching tool technical field, particularly a kind of manhole cover opener.
Background technology
Development in an all-round way along with China's economy, the development of cities and towns infrastructure is unprecedented, particularly the underground such as water conservancy, communication, electric power, combustion gas, heating power, fire-fighting, environmental sanitation is public and station-service facility is required for installing and overhauling all kinds of well lids, and the workload opening operation of this kind of well lid is the biggest, especially relate to the important pipeline maintenances such as national defence or occur unexpected incidents to need quick open manhole cover, but the limitation due to current technological means, make unlatching operation not carry out in time, have a strong impact on construction speed and leave over some potential safety hazards.
The Well cover unlatching tool that China is traditional at present has three kinds: cleek, pickax and sledgehammer are commonly called as " three-major-items ", and these three instrument correspond to also represent three kinds of open methods: one is to be triggered by well lid with cleek；Two is to be tilted by well lid with pickax；If first two is not all right, directly breaking well lid with sledgehammer, carry out destructive dismounting, after orcible entry, well lid can not be continuing with, and causes the waste of resource.Traditional open method is not only wasted time and energy, and can not realize opening to some well lids being difficult to open, and this well lid that can not open will have a strong impact on construction speed, driving a well this problem of lid in line with solving to open difficulty, project team's design have developed this semi-automatic manhole cover opener.
Utility model content
The technical problems to be solved in the utility model is for above-mentioned the deficiencies in the prior art, it is provided that a kind of manhole cover opener.
For solving above-mentioned technical problem, technical solution adopted in the utility model is: a kind of manhole cover opener, steps on pipe, containing tube, lever, regulation handle and crowbar external member including base plate, jack, foot；Described jack, foot step on pipe, containing tube is located on base plate, and the middle part of described lever is arranged on the height regulating rod of described jack；Wherein, described foot steps on pipe as the strong point, and described regulation handle can be accommodated in described containing tube.
In technique scheme, described crowbar external member includes bar portion, is provided with in the one end in bar portion and the installation portion of described lever location and installation, and the other end in bar portion is provided with the crowbar head inserting well lid hole.
In technique scheme, the two ends of described lever are both provided with the mounting structure allowing described crowbar external member install location respectively.
In technique scheme, described mounting structure is the location bar being provided with the diameter of axle in the end of lever more than lever diameter.
In technique scheme, also include opening auxiliary rod；This unlatching auxiliary rod includes bar portion, and the one end in this bar portion is provided with Handheld Division, and the other end in this bar portion is provided with crowbar head.
The beneficial effects of the utility model are: realize the convenience to well lid and open, and save the time of well lid unlatching and reduce difficulty.Overall structure of the present utility model is simple and practical, and has the function of storage regulation handle.

In figure, 1, base plate；2, jack；3, foot steps on pipe；4, containing tube；5, lever；6, regulation handle；7, crowbar external member；8, location bar；9, auxiliary rod is opened.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail.
As shown in Figure 1,2,3, 4, a kind of manhole cover opener, step on pipe 3, containing tube 4, lever 5, regulation handle 6 and crowbar external member 7 including base plate 1, jack 2, foot；Described jack 2, foot step on pipe 3, containing tube 4 is located on base plate 1, and the middle part of described lever 5 is arranged on the height regulating rod of described jack 2；Wherein, described foot steps on pipe 3 as the strong point, and described regulation handle 6 can be accommodated in described containing tube 4.
Wherein, described crowbar external member 7 includes bar portion, is provided with in the one end in bar portion and the installation portion of described lever 5 location and installation, and the other end in bar portion is provided with the crowbar head inserting well lid hole.Crowbar head, according to the difference in well lid hole, can arrange different specifications, the conventional J-type and T-shaped of including.Installation portion is installing ring, and the internal diameter of installing ring is bigger than the diameter of axle of the diameter of lever 5, location bar 8, and this installing ring just realizes location due to the jam of location bar 8.
Wherein, the two ends of described lever 5 are both provided with the mounting structure allowing described crowbar external member 7 install location respectively.Wherein, described mounting structure is the location bar 8 being provided with the diameter of axle in the end of lever 5 more than lever 5 diameter.It can also be the groove arranged along external diameter in the end of lever 5.
Wherein, also include opening auxiliary rod 9；This unlatching auxiliary rod 9 includes bar portion, and the one end in this bar portion is provided with Handheld Division, and the other end in this bar portion is provided with crowbar head.Opening auxiliary rod 9 is to be re-used as aid after using crowbar external member 7 to use.Crowbar head can be according to the difference in well lid hole, specially J-type, drum, L-type etc..
Operation principle of the present utility model: in a state of use, regulation handle 6 is taken out in containing tube 4, and regulation handle 6 is inserted in the adjustment seat of jack 2, with foot, foot is stepped on pipe 3 and slam as the strong point, crowbar external member 7 is sheathed on the end of lever 5, and utilizes the mounting structure of lever 5 end to position；Regulating handle 6 by people's hand drive, make jack 2 work, jack 2 makes lever 5 rise, and drives crowbar external member 7 to rise.After utilizing crowbar external member 7 that well lid is prized pine, then by opening auxiliary rod 9, well lid is pulled out from well lid mouth.
Above embodiment simply indicates that rather than limits this utility model, therefore all equivalences done according to the method described in this utility model patent claim change or modify, and are all included in this utility model patent claim.
