Abstract
The utility model relates to a pre-buried sleeve positioning device of a double-block sleeper for a passenger special line. The device comprises a positioning screw rod and a tapered rubber shaft; threads are formed on the outer contour of the rubber shaft; in order to reduce the shearing force between a positioning shaft and the sleeve, when the overall size of a sleeve is large, small blind holes are formed at the top of the rubber shaft; the upper part of the positioning screw rod is fixedly mounted at the lower part of the rubber shaft and shares the same axle therewith so as to form a whole; and the lower part of the positioning screw rod is in threaded connection with a positioning hole on the baseplate of a template. The positioning device ( positioning shaft) is directly mounted on a model working face and is fixed with the template via the positioning screw rod; and the sleeve is screwed on the positioning device ( positioning shaft). The utility model has the advantages of capability of ensuring the positioning accuracy of the pre-buried sleeve, high precision, convenient mounting and dismounting, low probability of damaging the pre-buried sleeve, and resuability, is operated conveniently during the production process of double-block sleepers, can greatly lower the labor intensity, improves the operational efficiency, and provides great assurance for the quality of products.
Description
Technical field
The utility model relates to a kind of double block type sleeper for passenger special line service sleeve positioner.
Technical background
Along with the fast development of China Express Railway, double-block type ballastless track is applied to many Lines for Passenger Transportation.In the production process of double-block type sleeper, sleeve pipe positioning requirements location accurately, the convenient installation and the demoulding, and the bolts location of adopting, the sleeve pipe of regular sleeper location from the installation and removal of model bottom, complex operation, and are difficult for satisfying the requirement of sleeve pipe positioning accuracy more.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of realization double-block type sleeper sleeve pipe accurately to locate, and is easy to operate, changes fast the double block type sleeper for passenger special line service sleeve positioner that production efficiency is high.
The purpose of this utility model is to be achieved through the following technical solutions: double block type sleeper for passenger special line service sleeve positioner, it is characterized in that this sleeper service sleeve positioner comprises positioning screw and rubber axis, described rubber axis is designed to cone shape, rubber axis top outline is threaded, the rubber axis top is provided with the center small blind hole of shearing force between the reducing of being used for being connected with pre-buried plastic bushing, described positioning screw top concentric is packed in the rubber axis bottom and forms integral body, and the positioning screw bottom is threaded with locating hole on the template plate.Positioning screw and rubber axis are the global formation structure.
This positioner (also being referred to as locating shaft), positioning screw and shuttering work face are fixed; The rubber axis outline is threaded, and the size that service sleeve is looked at the top is provided with blind hole, and service sleeve is tightened on the rubber axis.
The utility model adopts said structure, before the double-block type sleeper production process, the positioning screw of double block type sleeper for passenger special line service sleeve positioner (locating shaft) is screwed onto on the template plate, and service sleeve vertically is screwed on the rubber axis.Change the size of rubber axis in the time of can making according to the appearance and size of service sleeve.
Advantage of the present utility model is that it can guarantee the positioning accuracy of service sleeve, the precision height, and assembling and disassembling is convenient, and not fragile service sleeve can reuse.In the double-block type sleeper production process, easy to operate, can reduce labour intensity greatly, improve operating efficiency; Provide more guarantee to product quality.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a user mode schematic diagram of the present utility model;
Among the figure: 1, positioning screw, 2, rubber axis, 3, the rubber axis screw thread, 4, small blind hole, 5, template, 6, the model orientation hole, 7, service sleeve.
The specific embodiment
The contrast accompanying drawing is described further the utility model:
Referring to illustrated in figures 1 and 2, double block type sleeper for passenger special line service sleeve positioner (locating shaft) contains positioning screw 1 and rubber axis 2, rubber axis 2 is cone-shaped, rubber axis 2 outlines are provided with screw thread 3, the top is provided with center small blind hole 4, positioning screw 1 band standard thread, positioning screw 1 installs with rubber axis 2, locating hole 6 is set on the template plate 5, when sleeve pipe appearance and size is big, for reducing the shearing force of 7 of positioner (locating shaft) and service sleeves, so have small blind hole 4 at rubber axis 2 centers of positioner (locating shaft).
Positioning screw 1 is tightened in the locating hole 6 on the template plate 5.
In the double-block type sleeper production process, before concreting, earlier positioning screw 1 is screwed on the model end template 5, service sleeve 7 is entangled rubber axis 2 fully, make service sleeve 7 closely contact with model end template 5 surfaces.In building, vibrating process, service sleeve 7 can not be shifted under the frictional force effect of rubber axis 2 and can not float yet, and guarantees that its position dimension precision reaches the algnment accuracy requirement.Rubber axis 2 does not does not wear and tear after the sleeper demoulding, and positioning screw 1 does not separate and need not change with rubber axis 2, cleans out and can directly reuse, and rubber axis 2 wearing and tearing or rubber axis 2 separate the replacing locating shaft with positioning screw 1.
