Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art all belong to the protection scope of the present invention.
As shown in fig. 1-2, according to the utility model discloses a prevent side and move stop device for maintenance of ballastless track subgrade, including top layer board 1, top layer board 1 welds with the one end of screw rod 2, screw rod 2 and 3 threaded connection of nut, nut 3 keeps away from one side of top layer board 1 is equipped with sleeve 4, sleeve 4 cover is in screw rod 2 is outside, sleeve 4 keeps away from the one end and the bottom plate 5 welding of nut 3. The top supporting plate 1 and the bottom plate 5 are both square steel plates with the thickness of 10mm and the side length of 10 cm; the screw rod 2 is made of phi 60 finish-rolled deformed steel bar, and the length of the screw rod 2 is 180 mm. The sleeve 4 is a seamless steel pipe with the thickness of 8mm, the length of the sleeve 4 is 150mm, and the inner diameter of the sleeve 4 is 63 mm; the inner diameter of the nut 3 is 60mm, and the height of the nut is 50 mm. The length of the screw rod 2 is adjusted by rotating the nut 3, and the length is adjusted by 0.95mm in each turn. The bolt 2 is made of Q235, and the yield strength is 235 MPa.
For the convenience of understanding the above technical solutions of the present invention, the above technical solutions of the present invention are explained in detail through specific use modes below.
When the concrete positioning device is used specifically, the fixed end (namely the bottom plate 5) is installed firstly, and a grinder is adopted to cut a groove on the concrete (namely the base plate 7) surface needing to be limited before installation, so that the relative fixation of the position of the bottom plate 5 is ensured, and the slippage is avoided; then manually loosening the nut 3 to ensure that the top supporting plate 1 is basically attached to the anti-lateral-movement buttress 9 fixed on the other side, so that the device does not fall off after loosening, the anti-lateral-movement buttress 9 is positioned between the original-state materials 6, and the base plate 7 is positioned between the track plate 8 and the original-state materials 6; and finally, the screw 2 is screwed up by matching two persons, a wrench matched with the nut 3 is adopted during screwing, one person screws, the other person holds the sleeve 4 manually, and the force application termination condition of the wrench is based on the fact that the bottom plate 5 and the jacking plate 1 are tightly propped against the concrete surfaces on two sides.
When the device is used, the anchoring condition between the limiting device and the limiting abutment (namely the lateral movement preventing buttress 9) is kept, and the phenomenon that the track structure is deviated due to the failure of a local limiting device is avoided; in order to prevent the sliding between the steel plates at the two ends and the concrete, the contact surface of the steel plates and the concrete is limited by grooving with a grinder, and the depth is about 10 mm.
In conclusion, with the aid of the technical scheme of the utility model, the lateral movement prevention limiting device for ballastless track roadbed maintenance of the utility model has the advantages of simple structure, convenient assembly and disassembly and repeated use; the manufacturing and the operation are convenient, and the cost is low; the weight of more than 10t can be borne, the requirement of millimeter-scale precision for adjusting the length of the shoring is met, the underground excavation maintenance engineering can be widely applied to ballastless track subgrade underground excavation maintenance engineering, and the underground excavation maintenance engineering can also be applied to other similar engineering constructions requiring spacing, and has strong practicability.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
