The sleeve fixing part is provided with a fixing part body (1) comprising a guide head (7), a connector (8) and a working body (9); the guide head (7) is a cylinder arranged at the upper part of the fixing part body (1), and the diameter of the guide head (7) is same with the internal diameter of the embedded insulation sleeve (6); the connector (8) arranged in the middle of the fixing part body is a cone which is large at the upper part and small at the lower part; the working body (9) is arranged at the lower part of the fixing part body (1) and is provided with an O-shaped sealing ring (2) between the connector (8) and the working body (9); the working body (9) provided with annular knurls (10) is in interference fit with the internal diameter of the embedded insulation sleeve (6); and the working body (9) is provided with an internal thread which is fixedly connected into a whole with a track slab bearing platform (5) through double-screw bolts (4). The sleeve fixing part has the characteristics of precision and reliability in location as well as simplicity and convenience in operation.
Description
Technical field
The utility model belongs to the non-fragment orbit technical field, relates generally to the pre-buried spaghetti of a kind of fragment-free track slab punching block and uses the sleeve pipe fixed block.
Background technique
It all is to adopt the non-fragment orbit technology that non-fragment orbit technology applying more and more widely on world's high speed railway track, built in China become Lines for Passenger Transportation such as the Beijing-Tianjin be open to traffic, military wide and Beijing-Shanghai, the Shi Wu that building, Harbin-to-Dalian.
China on the basis of organizing relevant unit absorbing advanced foreign technology in 2004 by the Ministry of Railways, independent research CRTS I type, CRTS II type and CRTS III track plate, realized the production domesticization of fragment-free track slab and mould thereof.
Because direct rail on the track plate support rail platform of every CRTS I, CRTS II type and CRTS III type,, the rail plate needs therefore to install that some groups of spaghetti of rail are pre-buried advances in the track plate when pour into a mould, and it mainly acts on is the installation rail fastening; In order to guarantee the stability of spaghetti, need a kind of fixed block of design in order to fixing pre-buried spaghetti.
Summary of the invention
The purpose of the utility model is to propose the pre-buried spaghetti of a kind of fragment-free track slab punching block to use the sleeve pipe fixed block, the quick location of pre-buried spaghetti when making it can realize prefabricated non-fragment orbit, and have simple in structure, convenience operation.
The utility model adopts following technological scheme for accomplishing its invention task:
The pre-buried spaghetti of a kind of fragment-free track slab punching block is used the sleeve pipe fixed block, and described sleeve pipe fixed block has the fixed block body, and the fixed block body comprises guide head, connecting body and working body; Described guide head is the cylindrical body that is positioned at fixed block body top, and the diameter of guide head is identical with the internal diameter of pre-buried spaghetti; The connecting body that is positioned at fixed block body middle part is up-small and down-big circular cone stage body; Described working body is positioned at the bottom of fixed block body, and on the periphery between connecting body and the working body, has annular groove, in annular groove, has in order to prevent that concrete from getting into 0 RunddichtringO of pre-buried spaghetti; On described working body, be processed with annular knurl; The internal diameter interference fit of knurled working body and pre-buried spaghetti; Described working body has the internal thread that is fixedly connected through double-screw bolt and track plate support rail platform.
The pre-buried spaghetti of a kind of fragment-free track slab punching block that the utility model proposes is used the sleeve pipe fixed block, and the internal diameter interference fit of the working body of fixed block body and pre-buried spaghetti realizes the locking of pre-buried spaghetti; When needing release,, realize that pre-buried spaghetti separates with the sleeve pipe fixed block, have location characteristics accurate, reliable, easy and simple to handle with the direct jack-up track of hydraulic jack plate.
Description of drawings
Fig. 1 is the user mode schematic representation of the utility model.
Fig. 2 is the structural representation of fixed block body in the utility model.
Among the figure: 1, fixed block body, 2,0 RunddichtringO, 3, spring washer, 4, double-screw bolt, 5, track plate support rail platform, 6, pre-buried spaghetti, 7, guide head, 8, connecting body, 9, working body, 10, annular knurl.
Embodiment
In conjunction with accompanying drawing and specific embodiment the utility model is explained:
Like Fig. 1, shown in Figure 2, the pre-buried spaghetti of a kind of fragment-free track slab punching block is used the sleeve pipe fixed block, and the fixed block body 1 that the sleeve pipe fixed block is had comprises guide head 7, connecting body 8 and working body 9; Described guide head 7 is for being positioned at the cylindrical body on fixed block body 1 top, and the diameter of guide head 7 is identical with the internal diameter of pre-buried spaghetti 6; The connecting body 8 that is positioned at fixed block body 1 middle part is up-small and down-big circular cone stage body; Described working body 9 is positioned at the bottom of fixed block body 1, and on the periphery between connecting body 8 and the working body 9, has annular groove, in annular groove, has 0 RunddichtringO 2, gets into pre-buried spaghetti in order to prevent concrete; On described working body 9, be processed with annular knurl 10; The internal diameter interference fit of working body 9 and pre-buried spaghetti 6; Described working body 9 has internal thread, by double-screw bolt 4 working body 9 and track plate support rail platform 5 is fixedly connected.
During use; Be fixed on fixed block body 1 on the track plate support rail platform 5 of fragment-free track slab punching block through double-screw bolt 4; Tighten to the pretightening force of regulation with torque spanner; Inspection is also guaranteed the centre distance in length and breadth between the service sleeve fixed block, during the pre-track plate pre-buried spaghetti 6 is directly inserted the service sleeve fixed block, with wooden mallet touch make itself and sleeve pipe fixed block tensioner and with track plate support rail platform 5 closely connected getting final product; With the direct jack-up track of hydraulic jack plate, realize that pre-buried spaghetti separates with the sleeve pipe fixed block during die sinking.
