Description
Technical field
The utility model relates to a kind of well cover opening device, and it belongs to the lifting appliance class.
Background technology
The urban water supply and sewerage underground pipeline is the requisite urban operating mechanism in any one city; General plumbing underground pipeline is every all can be provided with a vertical shaft at a distance from certain distance; So that the staff clears up the plumbing underground pipeline through vertical shaft and safeguards, said vertical shaft generally all uses the well lid of a circular cast iron to cover, in case the personnel that pass by drop in the vertical shaft; Because the circular casting iron well lid and the harmony on road surface are bad; On the circular casting iron well lid on existing most of emphasis views road surface, the square well lid that all uses a cement or other material to process covers the casting iron well lid of circle.When using circular casting iron well lid, open this circular casting iron well lid is a very simple thing, sticks up rod with one and can easily open once sticking up, add a cover square well lid after; Because described square well lid is heavy many more than circular casting iron well lid, simultaneously, also can not show a candle to circular casting iron well lid on its intensity; The way that rod sticks up is stuck up in the use of continuing to use in the past, often square well lid is stuck up badly, and people are when opening square well lid for this reason; At first upright A-frame hangs up elevating mechanism on the described A-frame, and the lanyard of hoisting mechanism hangs on the hook of square well lid; Under the traction of elevating mechanism, square well lid is opened this mode of prior art; Operation is complicated, wastes time and energy, and further improved necessity is arranged.
Summary of the invention
The purpose of the utility model is to provide a kind of well cover opening device, to solve the problem that prior art exists.
A kind of well cover opening device of the utility model; Comprise support; It is characterized in that said support constitutes by a longitudinal holding pole and a lateral strut are vertical each other, the two ends of said lateral strut and the external end head of longitudinal holding pole are connected with feet, are connected with a jack device on the said support; The push rod of said jack device is provided with a stay cord fixed disk, is connected with some stay cords on the said stay cord fixed disk.
This well cover opening device of the utility model in use, is striden frame on square well lid with support earlier; Then stay cord is connected with hook on the square well lid, operate jack again, the push rod of jack moves upward; Through stay cord with square well lid pull-up; This well cover opening device of the utility model is simple and practical, convenient, can not cause damage by the square shaped well lid during use, and obviously the purpose of the utility model is achieved.
As further improvement, the longitudinal holding pole of said support and lateral strut all for cooperating the reduction sleeve structure that constitutes by outer tube and inner sleeve, can conveniently be regulated the size of support like this, thereby can be applicable to the unlatching of the square well lid that varies in size.
As further improvement; On the said feet scroll wheel is housed; The purpose that is provided with like this is to be convenient to the moving of well cover opening device of the utility model, and under the situation that scroll wheel is housed on the feet, the well cover opening device of the utility model can move on the square well lid comparatively easily.
As further improvement, said stay cord is an iron chains, because said iron chains is a chain of structure, like this, as long as connect with the stay cord fixed disk with different iron chains rings, can obtain different length very easily, so that adapt to the needs of construction condition.Certainly also can reach this purpose,, connect stay cord through flower basket bolt such as flower basket bolt being set as length adjustment device at the stay cord fixed disk through on stay cord or stay cord fixed disk, setting length adjustment device.
Description of drawings
Fig. 1 is a kind of well cover opening device structural representation that the utility model preferred embodiment provides.
Among the figure, 1 for lateral strut, 101 for outer tube, 102 for inner sleeve, 2 for longitudinal holding pole, 3 for jack, 4 for feet, 401 for scroll wheel, 5 strong for drawing, 6 for push rod, 7 for the stay cord fixed disk, 8 for square well lid, 9 be that well lid is linked up with.
The specific embodiment
A kind of well cover opening device and the accompanying drawing thereof that below will combine the utility model preferred embodiment to provide are described further the utility model.
A kind of well cover opening device that the utility model preferred embodiment provides; Shown in accompanying drawing 1, comprise support, it is characterized in that said support is made up of with a lateral strut 2 is vertical each other a longitudinal holding pole 1; The external end head of the two ends of said lateral strut 1 and longitudinal holding pole 2 is connected with feet 4; Be connected with a jack device 3 on the said support, the push rod 6 of said jack device 3 is provided with a stay cord fixed disk 7, is connected with some stay cords 5 on the said stay cord fixed disk 7.In this preferred embodiment, said longitudinal holding pole 1 and lateral strut 2 are all for cooperating the reduction sleeve structure that constitutes by outer tube 101 and inner sleeve 102.
In these preferable enforcement row; On the said feet 4 scroll wheel 401 is housed; The purpose that is provided with like this is to be convenient to the moving of well cover opening device of the utility model; Be equipped with on the feet 4 under the situation of scroll wheel 401, the well cover opening device of the utility model can move on the square well lid 8 comparatively easily.
In this preferred embodiment, said stay cord 5 is an iron chains, and well-known, said iron chains is a chain of structure, like this, as long as connect with stay cord fixed disk 7 with different iron chains rings, can obtain different length very easily, adapts to the needs of construction condition easily.
In sum, a kind of well cover opening device of the utility model comprises support; It is characterized in that said support constitutes by a longitudinal holding pole and a lateral strut are vertical each other; The non-union end of the two ends of said lateral strut and longitudinal holding pole is connected with feet, is connected with a jack device on the said support, and the push rod of said jack device is provided with a stay cord fixed disk; Be connected with some stay cords on the said stay cord fixed disk; The utility model is simple in structure, and has solved the square well lid operation complicacy of unlatching that prior art exists, the problem that wastes time and energy and damage square well lid easily.
The above is merely the specific embodiment of the utility model.But the utility model protection domain is not limited thereto.Any technician who is familiar with the present technique field is in the technical scope that the utility model discloses; The variation that can expect easily or replacement; All should be encompassed within the protection domain of the utility model, therefore, the protection domain of the utility model should be as the criterion with the protection domain of claim.
