Abstract
Train track fastening systems bolt locking device to effectively prevent bolt looseness, ensure the even running of train, and reduce the work load of railway rails maintenance and the intensity of labour who maintains the workman by a wide margin. Including bolt assembly, bullet strip, bolt assembly includes screw rod, nut and gasket, installs and exerts pretightning force through the packing ring to the bullet strip in the nut on screw rod upper portion. Screw rod upper portion is provided with locking movable sleeve, and this locking movable sleeve has the bayonet socket of making in nut outer profiled surface to and act on spacing of bullet strip.
Description
Technical field
The utility model relates to track structure, particularly a kind of locking device that effectively can prevent train rail fastener system bolt looseness.
Background technology
Railway track fastener system is the fastening devices of rail, to ensureing that very important effect is played in the even running of train.At present, most railway track fastener system adopts bolt, nut, packing ring to add the structure of spring secures rail to sleeper, although concrete composition and size are not quite similar, but structure is substantially substantially identical, and the VI of spring I, II type, IV type and elasticity separated rail fastening, Line for Passenger Transportation, V-type fastener, WJ-7 type fastener are all this class formations.
Can find from the fastening structure analysis of fastening elastic rod, packing ring under nut and the contact area of spring less, this is because spring is bent by spring round steel to form, and is arc section with the part of washer contacts, and also spring contact area is less to make packing ring like this.Although tightening nut, spring is bent to backing plate, spring relies on self elastic force and packing ring close contact and produces pretightning force, make spring when being subject to vibration and the impact force of track, rely on the distortion of spring can absorb vibrational energy and the impact energy of track, and the final shape recovering static state, ensure track to fix.But, under long-term track vibration and impact force, because the assembly relation of spring and packing ring, nut is not tight, nut easily loosens, from but the pretightning force of spring decline, its ability of bearing track vibration and impact declines, make rail relatively loosening, thus cause the vibration of track, produce potential safety hazard, if clamp nut not in time, cause connected effect, the fastener on these spring both sides loosened also can be loosened immediately following this, from but track produces larger vibration and displacement, this just creates very adverse influence to the operation of train.
Therefore, current railroad track maintenance work mainly concentrates on two aspects, one is the spacing checking both sides rail, two is check whether rail fastener system has loosening, if having to loosen to cause train to produce vibration by rail during track, this safety and steady to train runs and has a direct impact, so shouldn't be careless.Because rail fastener system is too many on a circuit, the track of a kilometer has several thousand, and existing technology mainly hand inspection, workman's amount of labour is very large, and easily undetected, causes potential safety hazard.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of train rail fastener system bolt locking device, effectively to prevent bolt looseness, guarantee the even running of train, and reduce the workload of railroad track maintenance and the labour intensity of surfaceman significantly.
It is as follows that the utility model solves the technical scheme that its technical problem adopts:
Train rail fastener system bolt locking device of the present utility model, comprise bolt assembly, spring, bolt assembly comprises screw rod, nuts and washers, the nut being installed on screw rod top applies pretightning force by packing ring to spring, it is characterized in that: described screw rod top is provided with anti-loosening sleeve, this anti-loosening sleeve has the bayonet socket making in nut outer surface, and acts on the positive stop strip of spring.
The beneficial effects of the utility model are, between rotating nut and fixing spring, arrange anti-loosening sleeve, effectively can prevent bolt looseness, guarantee the even running of train; Structure is simple, easy for installation, does not change the structure of existing rail clip system, reduces the workload of railroad track maintenance and the labour intensity of surfaceman significantly.
Accompanying drawing explanation
This manual comprises following four accompanying drawings:
Fig. 1 is the structural representation of the utility model train rail fastener system bolt locking device;
Fig. 2 is the top view of the utility model train rail fastener system bolt locking device;
The sectional view of Fig. 3 the utility model train rail fastener system bolt locking device;
The upward view of anti-loosening sleeve in Fig. 4 the utility model train rail fastener system bolt locking device.
Component shown in figure and corresponding mark: screw rod 10, nut 11, packing ring 12, spring 20, anti-loosening sleeve 30, bayonet socket 31, positive stop strip 32, snap ring 33.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
With reference to Fig. 1, Fig. 2 and Fig. 3, train rail fastener system bolt locking device of the present utility model, comprise bolt assembly, spring 20, bolt assembly comprises screw rod 10, nut 11 and packing ring 12, and the nut 11 being installed on screw rod 10 top applies pretightning force by packing ring 12 pairs of springs 20.Described screw rod 10 top is provided with anti-loosening sleeve 30, and this anti-loosening sleeve 30 has the bayonet socket 31 making in nut 11 outer surface, and acts on the positive stop strip 32 of spring 20.Namely anti-loosening sleeve 30 is set between rotating nut 11 and fixing spring 20, effectively can prevents bolt looseness, guarantee the even running of train.Structure is simple, easy for installation, does not change the structure of existing rail clip system, reduces the workload of railroad track maintenance and the labour intensity of surfaceman significantly.
With reference to Fig. 4, described bayonet socket 31 is positioned at anti-loosening sleeve 30, and its port is plum blossom-shaped.After nut 11 pairs of springs 20 apply pretightning force, put down anti-loosening sleeve 30 from the head of screw rod 10, nut 11 outline enters in bayonet socket 31, can not produce relative rotation between anti-loosening sleeve 30 and nut 11.With reference to Fig. 1 and Fig. 3, the quantity of described positive stop strip 32 is two, is extended downward the outside of turn of bilge in spring 20 by the lower port of anti-loosening sleeve 30.Being arranged so that of positive stop strip 32 can not produce relative rotation between anti-loosening sleeve 30 and spring 20.
With reference to Fig. 1, the lower inner wall of described anti-loosening sleeve 30 has an annular slot, and arrange the snap ring 33 that has opening in this annular slot, after anti-loosening sleeve 30 is enclosed within nut 11, snap ring 33 is stuck on the soffit of packing ring 12.
Some principles of the above the utility model train rail fastener system bolt locking device that just explains through diagrams, be not the utility model to be confined to shown in and in described concrete structure and the scope of application, therefore every corresponding modify of being likely utilized and equivalent, all belong to the scope of the claims that the utility model is applied for.
