Abstract
The utility model discloses a kind of switch lock, point lock, comprise for track switch inside clamping bottom tongue tongue shackle member, for track switch outside the rail shackle member of rail foot clamping and clamp nut; Described tongue shackle member has can block top tongue buckling groove bottom tongue and lower connecting part, and this connecting portion is fixed with screw rod; Described rail shackle member has the upper steel rail clip access slot that can block rail foot, and the bottom of rail shackle member is provided with through hole, and rail shackle member is loaded on described screw rod by the through hole of its underpart slidably; Described clamp nut is spun on the outside of described rail shackle member.The utility model switch lock, point lock adopts occlusion structure, and directly rigidly fix the root of tongue and stock rail, fixed form is that bolt screws, and improves longitudinal crystallized ability, effectively prevents the situations such as the vibrations of switch lock, point lock get loose from producing.Since the utility model switch lock, point lock comes into operation, substantially stop track switch position owing to going here and there the situation of branching off and causing mine car overturning track lowering, ensure that the life security of employee.
Description
Technical field
The utility model relates to a kind of fixed track of track switch and the locked instrument of tongue, specifically relates to a kind of switch lock, point lock.
Background technology
According to incompletely statistics, the accidents such as Electromechanical Transportation accident occupies the ratio of 20% ~ 30% in coal mining accident, track lowering overturning probably occupy about three one-tenth in shipping accident.Cause the reason of the accidents such as track lowering overturning to have a lot, wherein most typical is exactly that mine car causes string trouble in running, and then derives the generation of the accidents such as overturning track lowering because track switch is closed not tight.
In order to reduce the generation of string trouble situation, switch lock, point lock fixing apparatus of the prior art is that the mode adopting clamping plate and railway spike to fix locks to track switch, namely tongue is held out against with clamping plate, railway spike is knocked in sleeper along clamping plate limit, there is following drawback in this kind of fixed form: railway spike is knocked in sleeper and fixes clamping plate, fragile sleeper, railway spike easily loosens simultaneously, and switch locking was lost efficacy; Applicability is not strong yet in addition, and for cement sleeper track switch, this kind of scheme is infeasible.
Utility model content
The technical problems to be solved in the utility model is to provide one and point tongue and rail firmly can be locked, and can not damage sleeper, not by the switch lock, point lock of pillow track switch Effect of Materials.
For solving the problems of the technologies described above, the utility model switch lock, point lock, comprise for track switch inside clamping bottom tongue tongue shackle member, for track switch outside the rail shackle member of rail foot clamping and clamp nut; Described tongue shackle member has can block top tongue buckling groove bottom tongue and lower connecting part, and this connecting portion is fixed with screw rod; Described rail shackle member has the upper steel rail clip access slot that can block rail foot, and the bottom of rail shackle member is provided with through hole, and rail shackle member is loaded on described screw rod by the through hole of its underpart slidably; Described clamp nut is spun on the outside of described rail shackle member.
The utility model switch lock, point lock adopts occlusion structure, and directly rigidly fix the root of tongue and stock rail, fixed form is that bolt screws, and improves longitudinal crystallized ability, effectively prevents the situations such as the vibrations of switch lock, point lock get loose from producing.Since the utility model switch lock, point lock comes into operation, substantially stop track switch position owing to going here and there the situation of branching off and causing mine car overturning track lowering, decreased the potential safety hazard of overturning and bringing when outwelling, decrease the labour intensity of worker, ensure that the life security of employee.
As improvement of the present utility model, the top of described tongue shackle member has upper and lower tongue card adapter plate, and the space between upper and lower tongue card adapter plate forms described tongue buckling groove, and the width of upper and lower tongue card adapter plate is consistent with the width bottom tongue; The top of described rail shackle member has upper and lower rail card adapter plate, and the space between upper and lower rail card adapter plate forms described rail buckling groove, and the width of upper and lower rail card adapter plate is consistent with the width of rail foot.
Tongue buckling groove in the utility model be by the width upper and lower tongue card adapter plate consistent with the width bottom tongue between space formed, can ensure be engaged bottom tongue firm, simultaneously rail buckling groove be by the width upper and lower rail card adapter plate consistent with the width of rail foot between space formed, ensure that equally and to be engaged with the firm of rail foot.
As further improvement of the utility model, the relative both sides of described clamp nut are connected with tabular spanner, and the outside of tabular spanner is provided with lug boss.Adopt the clamp nut of said structure, tabular spanner is conducive to screwing this clamp nut on the one hand, can make rail shackle member uniform force when fastening reality is novel on the other hand, more firm to switch locking.
