TECHNICAL FIELD
[0001] The utility model relates to rail anti -down technology field, concretely is a kind of curve section rail stretching anti -down device. BACKGROUND
[0002] Rail is the main component of railway track. Its function is to guide the wheels of locomotive and rolling stock, bear the huge pressure of wheels, and transfer to the tie. Rail must provide continuous, smooth and minimum resistance rolling surface for wheels. In electrified railway or automatic block section, rail can also be used as track circuit.
[0003] The existing rail stretching is usually prevented from falling in the way of fastener reverse buckling, that is, the existing C4 elastic strip is buckled to stretch the rail from the inside and outside rail bottom. This way of fastener reverse buckling has defects. Since the fastener is buckled to the rail bottom, it is easy to loosen, causing poor adhesion, and the anti-down effect is poor.
[0004] Therefore, it is necessary to design a curve section rail stretching anti-down device. UTILITY MODEL CONTENT
[0005] The utility model aims to provide a kind of curve section rail stretching anti-down device to solve the problems raised in the above background.
[0006] To achieve the above purpose, the utility model provides the following technical scheme:
[0007] A kind of curve section rail stretching anti-down device, including mutually matched outside anti-down device and inside anti-rely device.
[0008] As a further scheme of the utility model: the outside anti-down device includes pre-buried insertion rod two, the pre-buried insertion rod two is fixedly installed with stress rod two, the pre-buried insertion rod two and stress rod two are fixedly installed in cross, and one end of stress rod two is rotatably connected with roller one.
[0009] As a further scheme of the utility model: the inside anti-rely device includes pre-buried insertion rod one, the pre-buried insertion rod one is fixedly installed with triangular structure at one end, the roller two is rotatably arranged on the horizontal rod away from the pre-buried insertion rod one of triangular structure, and stress rod one is fixedly installed in the connecting position of pre-buried insertion rod one and triangular structure longitudinally.
[0010] As a further scheme of the utility model: the stress rod two is fixedly installed with gasket at one end, and the gasket is rotatably connected with roller one.
[0011] In summary, the beneficial effects of this utility model are as follows: by installing the outer anti-tipping device and the inner anti-collision device on the inner and outer sides of the rail respectively, they slide and fit better with the bottom of the rail, thereby playing a role in preventing the rail from tipping over. This solves the defects of poor anti-tipping effect and easy popping out during the existing rail tensioning process, and improves construction efficiency and construction safety.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0016] Please see Figures 1-2 ,like Figure 1 As shown, a rail tensioning anti-tipping device for curved sections includes an outer anti-tipping device and an inner anti-collision device that cooperate with each other. The outer anti-tipping device and the inner anti-collision device are respectively fixedly installed on the inner and outer sides of the rail.
[0017] The outer anti-tipping device includes a pre-embedded insertion rod 26, on which a force-bearing rod 27 is fixedly installed. The pre-embedded insertion rod 26 and the force-bearing rod 27 are fixedly installed in a cross shape. Both the pre-embedded insertion rod 26 and the force-bearing rod 27 are made of round steel with a diameter of 18mm and a length of 200mm. One end of the force-bearing rod 27 is rotatably connected to a roller 18, with the two ends perpendicularly connected in a cross shape. The longitudinal connection point is located in the middle, and the transverse connection point is 65mm from the end of the roller 18. One end of the force-bearing rod 27 is fixedly installed with a washer 9, which is rotatably connected to the roller 18. The outer wall thickness of the roller 18 is 7mm. The top surface of the end uses a washer with an outer diameter slightly larger than the inner diameter of the roller, and the diameter of the inner end rod is smaller than the inner diameter of the roller. Together, they play a role in preventing slippage and sliding. After the outer anti-tipping device is installed, it forms a force-bearing surface with the rail corner. The pre-embedded insertion rod 26 is inserted longitudinally into the spring clip hole of the pre-embedded seat to form the anti-tipping force point of the rail. During installation, the insertion direction must be consistent with the tensioning direction of the rail to prevent the load-bearing rod 7 from coming out.
[0018] The inner side anti-relying device comprises a pre-buried insertion rod one 1, one end of which is fixedly installed with a triangular structural member 3, a roller two 5 being rotationally arranged on a crossbar 4 of the triangular structural member 3 away from the pre-buried insertion rod one 1, the roller two 5 being selected from high-strength pressure rollers, a stress rod one 2 being longitudinally fixedly installed at the connecting position of the pre-buried insertion rod one 1 and the triangular structural member 3, the pre-buried insertion rod one 1, the stress rod one 2 and the triangular structural member 3 all being circular steels with a diameter of 18 mm, the stress rod one 2 being in close contact with the inner side rail bottom to form an anti-relying stress surface and being capable of sliding along with the stretching of the steel rail, the stress rod one 2 and the sleeper surface forming a stress surface, the pre-buried insertion rod one 1 being inserted into the pre-buried seat elastic strip hole to form a steel rail anti-inversion stress point, and the insertion direction being required to be consistent with the stretching direction of the steel rail during installation so as to prevent the stress rod one 2 from being pulled out.
[0019] The outer side anti-inversion device and the inner side anti-relying device form a set, the installation spacing being arranged according to the on-site curve radius, curve super height and other unfavorable factors, generally being 10-20 m, and one set being installed beside the rail bottom roller.
