Description
Technical field
The utility model relates to field of urban rail more particularly to a kind of pore-formings of the long sleeper transverse direction preformed hole of subway
Device.
Background technique
With the fast development of urban track traffic, the long sleeper of subway is as the common basic components of subway line, demand
Amount is also increasing, but at present in the production process of the long sleeper of flowing water unit method subway, around generally existing transverse direction preformed hole
The presentation quality as caused by poorly sealed spillage is poor.The research and development of the long sleeper transverse direction preformed hole hole-forming device of the subway solve it
The technical problems such as the low, poor product quality of production efficiency present in his mounting means.
Utility model content
The purpose of this utility model aiming at above-mentioned deficiency provide a kind of structure be simple and convenient to operate, pore-forming rule, it is full
A kind of hole-forming device of the long sleeper transverse direction preformed hole of subway of the quality requirement of the sufficient long sleeper transverse direction preformed hole of subway.
The technical solution of the utility model is: a kind of hole-forming device of the long sleeper transverse direction preformed hole of subway,
Including the positioning baffle on limit plate, perforating device pipe, closure plate and model girder.
Setting positioning baffle and limit plate on the left of the perforating device pipe, perforating device pipe are each side arranged one piece and block up
Plate；
The limit plate is equipped with longitudinal hole, and perforating device pipe passes through the longitudinal hole on limit plate, and and limit plate
Weld together, limit plate lower end is inserted into the positioning baffle on model girder.
The perforating device pipe is equipped with a through-hole, which is kept off for dismounting hole-forming device by limit plate and positioning
Plate quick and precisely controls the verticality of perforating device pipe and mould form；The perforating device pipe is equipped with pattern draft, it is ensured that concrete vibration
Hole-forming device can be smoothly extracted after dynamic.
The closure plate is diameter 44mm, the steel plate with a thickness of 8mm, by real with perforating device pipe left and right ends firm welding
It now seals, concrete is avoided to enter in perforating device pipe.
The positioning baffle is unequal angle structure, and positioning baffle and model Main Girder Welding are secured.
The limit plate is the steel plate structure of 8mm thickness.
The perforating device pipe is wall thickness 5mm steel pipe.

Specific embodiment
Referring to attached drawing, a kind of hole-forming device of the long sleeper transverse direction preformed hole of subway,
Including the positioning baffle 4 on limit plate 1, perforating device pipe 2, closure plate 3 and model girder；
Positioning baffle 4 is set on the left of the perforating device pipe 2 and limit plate 1, perforating device pipe 2 are each side arranged one piece
Closure plate 3；
The limit plate 1 be equipped with longitudinal hole, perforating device pipe 2 pass through limit plate 1 on longitudinal hole, and with limit
Plate 1 welds together, and 1 lower end of limit plate is inserted into the positioning baffle 4 on model girder；Limit plate 1 is the steel plate knot of 8mm thickness
Limit plate 1 is inserted into positioning baffle 4 by structure before concreting, avoids loosening when vibratory concrete；Vibratory concrete
After molding, hole-forming device is dismantled, continues circulating repetition use next time after cleaning out.
The perforating device pipe 2 is wall thickness 5mm steel-tube construction, wherein perforating device pipe 2 is equipped with a through-hole 5, the through-hole 5
For dismounting hole-forming device, it is vertical with mould form that perforating device pipe 2 is quick and precisely controlled by limit plate 1 and positioning baffle 4
Degree；The perforating device pipe 2 is equipped with pattern draft, can smoothly extract hole-forming device after facilitating ensuring that vibratory concrete；Coagulation
Soil penetrates hole-forming device in the circular hole of model side before pouring, and quick and precisely controls pore-forming by limit plate 1 and positioning baffle 4
The verticality of device pipe and mould form, it is ensured that the Forming Quality of through-hole meets product requirement.
The closure plate 3 is diameter 44mm, the steel plate structure with a thickness of 8mm, by welding with 2 left and right ends of perforating device pipe
It securely realizes sealing, concrete is avoided to enter in perforating device pipe 2, the purpose of implementation model side opening sealing.
The positioning baffle 4 is unequal angle structure, and side and model Main Girder Welding are secured.
