Description
Technical field：
It the utility model is related to hydrofuge technical field inside cable shaft, more particularly to a kind of collapsible cable shaft well head mould
Tool.
Background technology：
It is to indicate well head size in design drawing in conventional power cable passage well head is prefabricated, diameter 800mm,
Height 200mm~300mm, but there is no unified mould standard in power construction.Workmen is usually using by woody type, brick
Block type, iron sheet ring or junked tire etc. are from molding jig.These irregular moulds, cause finished product is prefabricated problems to be present.
Such as：Mold material selection is simple, intensity is not high, lose circle deformation, rough surface finish is poor, it is not easy to remove, can not reuse.It is prefabricated
Well head deformation causes construction equipment not install, and cable can not be laid, it is impossible to improve cable laying quality and technological requirement.
The content of the invention：
The utility model provides a kind of collapsible cable shaft well head mould, and mould is lack of standardization solving in the prior art,
The problem of losing circle deformation.
The utility model provides a kind of collapsible cable shaft well head mould, including：Three pieces of die ontologies, four pieces of connecting plates with
And two support bars；Three pieces of die ontology first places connect to forming cylindrical sides, one of die ontology and other two pieces of moulds
Tool body junction is hinged；The circumferentially uniform four pieces of connecting plates of cylindrical sides that three pieces of die ontologies are formed, often relative two pieces
A support bar is connected between connecting plate.
Preferably, two gate dismounting handles are oppositely arranged and are connected on the cylindrical sides that three pieces of die ontologies are formed.
Preferably, circumferentially disposed reinforcement in the middle part of every piece of die ontology.
Preferably, support bar includes：Two leading screw support bases and leading screw；Leading screw both ends respectively connect a leading screw support base,
Leading screw support base one end is fixedly connected with connecting plate by connecting pin, and the leading screw support base other end is threaded hole, with leading screw end
Portion is threadedly coupled.
Preferably, two pieces of die ontology junctions of one of die ontology and other are connected by hinge.
Preferably, three pieces of die ontology shapes are identical, it is the banding camber steel plate of 120 ° of central angle.
The utility model beneficial effect includes：Mould leading screw stretches principle, rational in infrastructure, material hardness is strong, production process
Simply, low reusable, the indeformable, prefabrication of cost does not lose circle, capable of expansion and contraction, is convenient to mount and dismount, the prefabricated well head quality of specification
And technique.By the prefabricated experiment of live well head, do not find that circle phenomenon is lost in deformation, reach technique, quality requirement, qualification rate is reachable
100%.Specification mould standard is unified, prevents the phenomenon of conventional mould abuse, cost-effective, raising effect.

Embodiment：
In consideration of it, the utility model provides a kind of collapsible cable shaft well head mould, below in conjunction with Figure of description pair
Preferred embodiment of the present utility model illustrates.
Refering to shown in Fig. 1 and Fig. 2, a kind of collapsible cable shaft well head mould, including：Three pieces of die ontologies, 1, four piece of connection
Plate 2 and two support bars 3；Three pieces of first places of die ontology 1 connect to forming cylindrical sides, one of die ontology 1 and its
He is hinged two pieces of junctions of die ontology 1；The circumferentially uniform four pieces of connecting plates 2 of cylindrical sides that three pieces of die ontologies 1 are formed, often
A support bar 3 is connected between two pieces of relative connecting plates 2.
Two gate dismounting handles 4 are oppositely arranged and are connected on the cylindrical sides that three pieces of die ontologies 1 are formed.Every piece of mould
Has the circumferentially disposed reinforcement 11 in the middle part of body 1.Support bar 3 includes：Two leading screw support bases 31 and leading screw 32；The both ends of leading screw 32 are each
A leading screw support base 31 is connected, the one end of leading screw support base 31 is fixedly connected with connecting plate 2 by connecting pin 311, leading screw support
31 other ends of seat are threaded hole, are connected with the end thread of leading screw 32.One of die ontology 1 and other two pieces of die ontologies
1 junction is connected by hinge 5.Three pieces of shapes of die ontology 1 are identical, are the banding camber steel plate of 120 ° of central angle.
Collapsible cable shaft well head mould in the utility model, it is 6mm, the highly band-like steel for 200mm from thickness
Plate, convolution weld two hinges into 3 1/3rd arc surface bodies as die ontology 1, one of both ends of die ontology 1
5, it is be hinged with other two die ontologies 1, formed two fans can inside outer folding movable part, three formation diameters of die ontologies 1
For the cylinder of the supreme bottom surfaces of 800mm, in four orientation of the cylinder interior that three die ontologies 1 are formed, one is welded
