Description
Affiliated technical field
The utility model belongs to positioner, is meant a kind of high speed railroad rail plate pre-built sleeve quick positioning device especially.
Background technology
Must guarantee its safety and stability because bullet train is in operation, very high to track flatness, two guideway centreline's distances and long-time stability requirement, originally traditional track structure form can not satisfy its needs.Current high-speed railway mostly adopts the track installation form of no tiny fragments of stone, coal, etc. railway roadbed, the non-fragment orbit that is applied to China Express Railway has three kinds of modes: the one, and double-block type sleeper (being used for military wide, Zheng Xi high ferro), the 2nd, Bo Geban (being applied to the Beijing-Tianjin high ferro at present), the 3rd, frame-type flat board (being applied to high ferro special lines such as wide Shenzhen and Hong Kong, east, Hainan ring, Shanghai and Nanjing).Be double-block type sleeper or slab track all need be imbedded the fastener connecting bolt that is used to get on the right track in the concrete product service sleeve, this service sleeve requires that burial place is accurate, perpendicularity good and can not float.
Sleeper or track plate all adopt formed in mould method, and the service sleeve reference column is installed on mould, will carry out high frequency tamping in the process of making sheet (pillow) simultaneously, make the inner closely knit and smooth in appearance of track plate or sleeper finished product.Requirement to reference column is to guarantee that the accurate location of service sleeve reaches and the perpendicularity of base plate, also will install in the process of vibrating firmly, can not float.Simultaneously simple to operate again in knockout course, be easy to the demoulding.This is a present technical barrier in sleeper or track plate manufacturing process.
The reference column frame mode that is applied to high ferro track plate or sleeper at present has three kinds substantially, all exists weak point:
1, reference column adopts the compounded rubber body, and appearance has the screw thread that matches with service sleeve, relies on the rubber screw thread to tighten when fastening, relies on the crimp of rubber screw thread therefrom to pull out during the demoulding.Exist and be difficult for the demoulding and fragile two problems of rubber screw thread.
2, reference column adopts the cylindrical metal body, does not have screw thread, and the appearance annular knurl relies on tight fit and frictional force fastening to increase frictional force between service sleeve and the reference column.Owing to there is error in the casing inner diameter size, all locking causes service sleeve come-up, inclination, displacement in the high frequency tamping process, oozes slurry in the pipe, causes substandard product.
3, reference column adopts metallic object, appearance has the screw thread that matches with service sleeve, reference column passes die bottom plate but does not link to each other with base plate, be provided with reference column tensioning and tripping-gear in the bottom, before being installed, service sleeve need elder generation that reference column is fastening, need unclamp strainer earlier during the demoulding, extract together with one of reference column, and then from the track board finished product, unload.Because guarantee that the service sleeve position is accurate, be tight fit between reference column and the base plate, the problem of existence is a demoulding difficulty, and every dozen of plates need repeat to install reference column, and program is loaded down with trivial details, and working strength is big.And maximum hidden danger is that security incident very easily takes place workman's operation under plate at the dismounting track plate of need slinging during reference column.
The utility model content
The purpose of this utility model is to provide a kind of pinpoint high speed railroad rail plate pre-built sleeve quick positioning device of service sleeve of can realizing locating fast and load and unload, guarantee simultaneously.
Overall technology design of the present utility model is:
