Abstract
The utility model relates to a steel rail fastening device, which belongs to the fastening device of the I-shaped steel especially the guide rail. The utility model comprises a bracket, two fastening plates connected to the bracket, and wedge-shaped blocks arranged among the fastening plates and the bracket. The utility model is characterized in that screw holes are arranged on the fastening plates, mating holes or grooves corresponding to the screw holes are arranged on the wedge-shaped block, and the lower ends of screws are matched with the fitting holes or grooves arranged on the wedge-shaped blocks after the screws are screwed in the screw holes. The utility model ensures the safety of the rail transport, prevents the robbery accident of the wedge-shaped blocks, increases the maintenance period of the rails, and lightens the labor intensity of workers.
Description
The utility model is a kind of rail clamping device, belongs to the particularly fastening devices of railroad rails of i iron.
Present in the anchor clamps of fixed rail, the fastening form of wedge that is of employing.The base, both sides of i iron lays respectively between the base and clamping plate of anchor clamps, wedge is placed between i iron base and the clamping plate again, makes it fastening through hammering.Owing to there are not other fixing meanss, wedge because train through out-of-date vibration, can make it loosening, cause the danger of derail easily, thereby it is fastening just to need to arrange the workman often to beat along the road after after a while.In addition, because wedge is loosening, also through regular meeting stolen incident appears.
The purpose of this utility model is: design a kind of rail clamping device, make it can keep tightening state, and prevent the generation of stolen phenomenon effectively.
The utility model comprises two clamping plate that carriage is connected with carriage and the wedge between clamping plate and the carriage, it is characterized in that: have screw hole on the clamping plate, and corresponding mating holes or groove, screw and screw hole spin mating holes or groove fit on back its lower end and the wedge also arranged on the wedge.Unlike the prior art, the utility model has adopted screw to make wedge location, and it is loosening that it is difficult for, and, understand between back screw and the clamping plate through after a while and can't dismantle, thereby prevent that effectively wedge is stolen because of corrosion is connected it.Screw hole at the utility model middle clamp plate is a stepped hole, and the size of its top, bottom adapts with the land part and the screw portion of screw respectively, and screw portion and this hole spin.This structure embeds in the clamping plate screw and is difficult for being turned after installing, thereby has further strengthened anti-theft effect.And when wedge of the present utility model adopts form of grooves, groove can adopt a skewed slot, make it more shallow near the most advanced and sophisticated groove of wedge, darker near its groove than blunt end, thereby when train motion and extruding wedge when outwards moving, screw cooperates meeting more fastening with wedge, thereby prevents dangerous generation more effectively.
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
Fig. 1 is the sectional view in present embodiment front;
Fig. 2 is the side sectional view of present embodiment wedge;
Wherein, 1-screw, 2-clamping plate, 3-wedge, 4-supporting plate, 5-clamping plate, 6-location-plate, 7-groove.
Present embodiment is made up of the clamping plate on its carriage and the carriage 2, wedge 3, screw 1.Wherein, carriage comprise a supporting plate 4 and be fixed in supporting plate 4 belows and with vertical location-plate 6, have reinforcing rib or support bar between supporting plate 4 and the location-plate 6.Two clamping plate 2,5 of present embodiment are formed by the dual-side bending of supporting plate 2, and they and supporting plate form an angle.On clamping plate 2 a step-like screw hole is arranged therein, screw 1 spins with this hole and its land part is embedded in the hole.Wedge 3 has an inclined notches formed 7 on it between clamping plate 2 and supporting plate 4, this groove is more shallow near the most advanced and sophisticated place of wedge 3, and darker than the blunt end place near it, the lower end of screw 1 is arranged in this groove.
Use the utility model can guarantee safety of railway transportation preferably, prevent the generation of the stolen situation of wedge, can also increase the maintenance cycle of railway, alleviate working strength of workers.
Claims (3)
1, a kind of rail clamping device, comprise the wedge (3) between two clamping plate (2), (5) and at least one clamping plate and the carriage that carriage is connected with carriage, it is characterized in that: have screw hole on the clamping plate, cooperate with groove (7) with mating holes on the wedge (3) and also have corresponding mating holes or groove (7), screw (1) to be connected its lower end, back with screw hole on the wedge (3).
2, rail clamping device according to claim 1 is characterized in that: the screw hole on the clamping plate is a stepped hole, and the size of its top, bottom adapts with the land part and the screw portion of screw (1) respectively, and screw portion and this hole spin.
3, rail clamping device according to claim 1 and 2 is characterized in that: the groove (7) on the wedge (3) is a skewed slot, and it is more shallow near the most advanced and sophisticated part of wedge (3), and is darker than the part of blunt end near wedge (3).
