Abstract
The utility model relates to a novel environment protection concrete sleeper. A spring is anchored in a sleeper, a plastic casing tube is screwed in the spring, the outer part of the plastic casing tube forms a spiral tooth shape which is matched with the spring, and the inner part has a tooth-shaped structure which forms a screw thread fit with the lower end of a spiral dog nail. The spring and the plastic casing tube are anchored in the sleeper in advance by the utility model, the spring is a steel element, the cohesive force of the steel element and cement is strong, and the spring is firmly embedded into the sleeper after anchored. Because the cohesiveness of plastics and the cement is poor, after the plastic casing tube is damaged, the plastic casing tube is directly screwed out of the spring. After the plastic casing tube is screwed out, the cement naturally forms a screw thread structure, a new plastic casing tube can be screwed in the cement again, the sleeper does not need to be replaced, and thus, the service life of the sleeper is prolonged. The plastic casing tube forms an internal screw thread structure, the spiral dog nail can be directly screwed in the plastic casing tube, and the utility model can reduce workload, and simultaneously can prevent environment pollution. When the sleeper needs to be drawn out and changed, the spiral dog nail is directly screwed out, and can be drawn out from the bottom part of a steel rail, the operation of lifting of a steel rail is not needed, and workload is reduced.
Description
Technical field
The utility model relates to the concrete sleeper structure that the railway steel rail laying is used.
Background technology
The existing concrete sleeper is to reserve earlier the screw spike anchoring hole, after sleeper is laid on the line and is finished, the agent of field by using sulfur cement mortar anchorage with screw spike anchoring in sleeper.The deficiency that this mode exists is: railway spike be installed as the site operation fixation, workload is very big; The sulfur cement mortar anchorage agent of adopting easily causes surrounding environment to pollute, and is unfavorable for environmental protection; Railway spike is fixed in the sleeper, and railway spike needs the integral replacing sleeper after damaging; During sleeper replacement, because screw spike exceeds rail foot surface, need carry out rail and lift operation, workload is bigger.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of novel environment friendly concrete sleeper, adopts easy mechanical system that screw spike can be mounted and dismounted easily.
Novel environment friendly concrete sleeper of the present utility model; it is characterized in that anchoring has spring in the concrete sleeper; screw in plastic bushing in the spring, the plastic bushing outside has the spiral tooth form that cooperates with spring, and inside has the tooth form structure with screw spike lower end threaded engagement.
The utility model is anchored at spring and plastic bushing in the sleeper earlier, spring is a steel part, and the adhesion stress of steel part and cement is strong, and the anchoring rear spring can embed in the sleeper securely, because the caking property of plastics and cement is bad, after damaging appears in plastic bushing, can directly plastic bushing be screwed out from spring, after the back-out, cement forms helicitic texture naturally, can screw in new plastic bushing again, needn't change sleeper, prolong the application life of sleeper.
Plastic bushing is a female thread structure, and screw spike can directly screw in the plastic bushing, than adopting the fixedly mode of screw spike of sulfur cement mortar anchorage agent, has significantly reduced workload, has avoided environment pollution simultaneously.Screw spike screws in (installation) or screws out (dismounting) all more convenient.When carrying out sleeper replacement, screw spike is directly screwed out, can extract out from rail foot, needn't carry out rail and lift operation, reduced workload.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1 sleeper, 2 springs, 3 screw spikes, 4 plastic bushings, 5 round platforms
The specific embodiment
As Fig. 1, anchoring has spring 2 in the concrete sleeper 1, screws in plastic bushing 4 in the spring, and plastic bushing 4 outsides have the spiral tooth form that cooperates with spring 2, and inside has the tooth form structure with screw spike 3 lower end threaded engagement.Screw spike 3 can directly screw in or screw out plastic bushing 4.For the convenient spanner that adopts screws in plastic bushing with screw spike, flat-shaped structure is processed at round platform 5 places of screw spike.
Claims (1)
1, a kind of novel environment friendly concrete sleeper; it is characterized in that the interior anchoring of concrete sleeper (1) has spring (2); screw in plastic bushing (4) in the spring, the plastic bushing outside has the spiral tooth form that cooperates with spring, and inside has the tooth form structure with screw spike (3) lower end threaded engagement.
