[0002] At present, in the construction of long sleeper embedded tracks, since the fasteners for fixing the sleepers are rigidly connected to the sleepers, the service life of the sleepers will be affected, and the sleepers cannot be fixed firmly. During the long-term operation of the train, the fasteners will become loose under the action of external forces. Generally, a layer of track rubber pad needs to be laid between the fasteners and the sleepers. However, during the installation process of the track rubber pad, since there is no positioning device to assist in positioning, the track rubber pad often deflects and is misaligned when the bolts of the fasteners are tightened, thereby affecting the connection strength of the sleepers and reducing the driving safety. It can be seen that there is an urgent need for a positioning frame for installing the track rubber pad to position the track rubber pad at a predetermined position of the sleeper during the installation process, so that the track rubber pad will not deflect or be misaligned during the installation of the fasteners, improve the locking strength of the fasteners on the sleepers, and thus improve the driving safety.

Then, the two buckling lock arms 400 are pulled down until these two buckling lock arms 400 are buckled on two opposite side walls of the sleeper respectively, so that the positioning frame 200 presses the track rubber pad tightly. Moreover, under the action of the anti - reverse mechanism 500, the two buckling lock arms 400 will not release the state of buckling the side wall of the sleeper without being actively released manually. Finally, the installation operation of the fasteners is carried out. After the installation is completed, the two buckling lock arms 400 are actively released, and then the installation operation of the fasteners at the next position is carried out. In summary, the present invention can position the track rubber pad to the predetermined position of the sleeper during the installation process, so that the track rubber pad will not be displaced or misaligned during the installation of the fasteners, improving the locking strength of the fasteners to the sleeper, and thus improving the driving safety.

[0029] As a preferred embodiment of the present invention, as Figure 3As shown in the figure, the positioning frame body 100 includes two strip-shaped seats arranged at intervals along the length direction of the sleeper. Between these two strip-shaped seats, two adjusting rod groups 300 are provided, and these two adjusting rod groups 300 are arranged at intervals along the width direction of the sleeper. Each fastening and locking arm 400 is connected to the corresponding adjusting rod group 300. Among them, the strip-shaped seat includes a vertical plate 101 and a horizontal plate 102 connected at a right angle, and both the vertical plate 101 and the horizontal plate 102 extend along the width of the sleeper. Both ends of each adjusting rod group 300 are detachably connected to the two vertical plates 101 of the two strip-shaped seats, and a plurality of insertion holes are arranged at intervals along the length direction on the horizontal plate 102. The positioning frame 200 of this embodiment includes a rectangular frame body 201, and a plurality of insertion joints 202 are constructed on the upper end surface of the rectangular frame body 201, and these insertion joints 202 are respectively inserted into the insertion holes 103 on the two horizontal plates 102. Different models of rectangular frame bodies 201 can be replaced in this embodiment, so as to realize the positioning and pressing of track rubber pads of different sizes. In order to prevent the rectangular frame body 201 from sliding relative to the track rubber pad in this embodiment, a layer of anti-slip layer is fixed on the lower end surface of the rectangular frame body 201.

[0030] As a preferred embodiment of the present utility model, as Figure 3 , 4 shown, the adjusting rod group 300 includes an adjusting sleeve 302 and two connecting rods 301. Among them, these two connecting rods 301 are arranged oppositely, and the mutually remote ends of the two connecting rods 301 are respectively detachably connected to the two strip-shaped seats, that is, the end of the connecting rod 301 is threadedly connected to the corresponding vertical plate 101, and a fastening nut 303 is threadedly connected to the connecting rod 301, and the fastening nut 303 is screwed tightly on the corresponding vertical plate 101. The mutually close ends of the two connecting rods 301 respectively extend into the two ends of the adjusting sleeve 302, and each connecting rod 301 is threadedly connected to the adjusting sleeve 302. By rotating the adjusting sleeve 302, the two connecting rods 301 move closer to or away from each other, so as to realize the adjustment of the distance between the two strip-shaped seats, realize the fixation of different models of positioning frames 200, and finally realize the positioning of track rubber pads of different models.
