Abstract
The utility model provides a concrete sleeper embedded parts positioning device, comprising a bolt passing through a sleeper injection-molding plate and arranged in an embedded parts fixation hole, characterized in that: an inner sleeve mated and connected with the bolt is arranged in the embedded parts fixation plate, an outer sleeve sleeved with the bolt and a spring are arranged outside the sleeper injection-molding plate. The embedded parts are fixed on the sleeper injection-molding plate in advance. After the sleeper is completely casted and the concrete solidifies, the bolt and the inner sleeve rotate together by rotating the nut, therefore the inner sleeve is uncoupled from the embedded parts fixation hole and the bolt and the inner sleeve are easily separated from the embedded parts under the function of the spring and stripped from the mold, therefore the embedded parts are accurately positioned in the sleeper, thus the stripping speed is quick, the labor and time are saved and the embedded parts are accurately position in the sleeper. The unconvenience for mounting the rail due to eccentric embedded parts and the safety hidden trouble are thoroughly solved and the concrete sleeper up-to-standard rate is effectively increased.
Description
Technical field
The utility model relates to a kind of positioner, and particularly a kind of sleeper built-in fitting positioner belongs to the railroad track auxiliary facility and builds servicing unit design and manufacturing technology field.
Background technology
Concrete sleeper is one of railway main component, thereby adopt service sleeve and bolt that fastener is installed in rail is installed above the sleeper.
Along with the development of domestic railway, service sleeve can be controlled the rail spacing accurately in concrete sleeper.Pre-buried locate mode of sleeve pipe and device thereof that present domestic production concrete sleeper is adopted have been difficult for satisfying sleeper to the required precision of service sleeve pitch-row; Directly influence sleeper and steel rail laying; Even incur loss through delay the construction of railways construction because of laying, increase the railway construction cost because of waste products in a large number simultaneously.Therefore be necessary prior art is improved.
Summary of the invention
Cause the site operation difficulty for solving existing concrete sleeper built-in fitting fixing hole because of there being off-centre, percent defective is high, influences the railway construction construction speed, increases problems such as railway construction cost, and the utility model provides a kind of sleeper built-in fitting positioner.
The utility model provides a kind of like this sleeper built-in fitting positioner; Comprise the bolt that passes the sleeper cast template and place the built-in fitting fixing hole; It is characterized in that being provided with in the built-in fitting fixing hole the interior cover matched with bolt, the sleeper cast template is provided with overcoat and the spring that is socketed on the bolt outward, so that accurately be fixed on built-in fitting in the template; After treating that sleeper cast finishes and solidifies; Take out bolt, overcoat, template, interior cover successively, and in bolt screws out, behind the cover, bolt and outer being enclosed within the spring action are separated easily with built-in fitting.
The inner hole wall that overlaps in said is provided with the internal thread with the bolt bolt; The outer surface of interior cover is provided with the external screw thread with built-in fitting fixing hole bolt; So that, fix through external screw thread and built-in fitting again, thereby built-in fitting be accurately positioned on the sleeper through internal thread and bolt.
Said outer putting is provided with axis hole; Spring eye is established in the axis hole lower end; So that being with the through hole that bolt that spring, its lower end be provided with nut passes on overcoat axis hole, the template on it is connected with interior cover in the built-in fitting fixing hole; Thereby built-in fitting accurately is fixed in the template, treat that sleeper cast finishes after, built-in fitting is accurately positioned on the sleeper.
Said built-in fitting outer surface is provided with screw thread, so that built-in fitting firmly is connected with sleeper.
The utlity model has advantage and effect: adopt such scheme, can built-in fitting be fixed on the sleeper cast template in advance, treat that the sleeper cast finishes and solidifies after; Through the rotation nut bolt is rotated synchronously, the interior cover that links to each other with bolt also together rotates, thereby makes the disengagement that is spirally connected of interior cover and built-in fitting fixing hole; Be enclosed within the spring action in then bolt reaches and separate with built-in fitting easily, and the together demoulding of template, thereby built-in fitting is accurately positioned on the sleeper; Not only the demoulding is quick, and is time saving and energy saving, and built-in fitting is accurately positioned in the sleeper; Fundamentally solved because of eccentric rail inconvenient installation that causes of built-in fitting and the problem that has potential safety hazard; Effectively improve the concrete sleeper qualification rate, made things convenient for the on-the-spot auxilliary fast of rail to establish and install, improved operating efficiency greatly.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done and to be further described.
Like Fig. 1; The sleeper built-in fitting positioner that the utility model provides; Comprise the bolt 6 that passes the through hole 11 on the sleeper casting mold base plate 12 and place the fixing hole 9 of built-in fitting 8; Wherein be provided with the interior cover 7 matched in the fixing hole 9 of built-in fitting 8 with bolt 6, said in the inner hole wall of cover 7 be provided with the internal thread with bolt 6 bolts, the outer surface of interior cover 7 is provided with the external screw thread with built-in fitting 8 fixing holes 9 bolts; Be provided with overcoat 4 and the spring 2 that is socketed on the bolt 6 outside the sleeper casting mold base plate 12, overcoat 4 is weldingly fixed on the die bottom plate 12; Said overcoat 4 is provided with axis hole 5; Spring eye 3 is established in axis hole 5 lower ends, so that be with spring 2 on it, the through hole 11 that the bolt 6 that its lower end is provided with nut 1 passes on overcoat 4 axis holes 5, the die bottom plate 12 is connected with interior cover 7 in built-in fitting 8 fixing holes 9; And cover 7 is fixed on the bolt 6 in making through welding manner; After treating that sleeper 10 cast finishes and solidifies, through rotation nut 1 bolt 6 is rotated synchronously, the interior cover 7 that links to each other with bolt 6 is together rotation also; Thereby the disengagement that is spirally connected of cover 7 and built-in fitting 8 fixing holes 9 in making; Then bolt 6 and interior cover 7 separate with built-in fitting 8 under spring 2 effects easily, and with the together demoulding of die bottom plate 12, thereby built-in fitting 8 is accurately positioned on the sleeper 10.
