Description
Technical field
The utility model relates to wedge self-locking automatic sedimentation compensation arrangement for a kind of changeover portion.
Background technology
Rail track structure is comprised of line (roadbed circuit), bridge, tunnel, station, and the track structure of circuit, according to the difference of classification of rail and technical standard, can be laid Ballast track and non-fragment orbit.The stiffness difference of different line constructions is remarkable, train by time cause the displacement non_uniform response of rail level, meanwhile, the foundation settlement of different structure thing is also inhomogeneous, very easily produces distortion and cause rail level to bend near transition point.When train passes through at a high speed, the mutual dynamic action of vehicle and circuit aggravates, and causes the serious irregularity of rail level, the deterioration of acceleration line line state, and the maintenance cost of increase circuit, even threatens traffic safety when serious.
For reducing the sudden change of circuit rigidity between different line constructions, need to changeover portion be set in the junction of non-fragment orbit and Ballast track, roadbed and bridges and culverts, roadbed and tunnel and embankment and cutting, to realize the gradual transition of circuit rigidity within the scope of changeover portion.The processing method that changeover portion is conventional has: 1, in the softer side of changeover portion, increase track vertical rigidity, such as adopting, within the scope of changeover portion, adjust length of sleeper and spacing improves orbit rigidity, by using the overlength sleeper progressively increasing and reducing the progressively transition that sleeper pitch can be realized orbit rigidity.2, in the harder side of changeover portion, reduce track vertical rigidity, generally adopt at the softer rubber cushion of the rail underlay of track; At the large rubber cushion of pillow underlay high resiliency; Increase railway ballast thickness on bridge, overlay railway ballast pad etc.3, auxiliary rail is set and improves track structure frame stiffness, auxiliary rail is comprised of four rail that are attached on sleeper, and two are being moved between rail, and two in operation rail outside.Said method has good effect for the stiffness variation rate reducing between different line constructions, but can not solve the rail level bending problem being caused by differential settlement between different structure, therefore has certain limitation, can not solve the irregularity problem of changeover portion completely.
Summary of the invention
The purpose of this utility model is just to provide a kind of simple in structure, reliable operation, can be used on the Ballast track railway roadbed in different line construction transition location wedge self-locking automatic sedimentation compensation arrangement for the changeover portion of the irregularity problem that solution circuit differential settlement causes.
Wedge self-locking automatic sedimentation compensation arrangement for changeover portion of the present utility model, comprise pedestal, dust cover, sealing ring, it is characterized in that, the column part of cylindricality wedge bearing support is contained in the cylindrical hole of pedestal and forms matched in clearance, between cylindricality wedge bearing support and pedestal, dust cover is housed, dust cover and cylindricality wedge bearing support are affixed with screw, the lower end of cylindricality wedge bearing support is to become the cammed surface of 6～12 ° with level, by the tapered wedges with it with equal angular cammed surface, supported, tapered wedges is arranged on the inner chamber bottom surface of pedestal, by dive key, be flexibly connected with pedestal, the guiding that can do to move left and right, dive key is the bottom surface at pedestal by screw attachment, spring and spring conductor rod are housed in tapered wedges endoporus, the frictional force moving right when overcoming on tapered wedges inclined-plane without active force, and the pre compressed magnitude of regulating spring is pretightning force, the little head end of tapered wedges contacts with original position adjusting screw(rod), the adjustment operation of original position adjusting screw(rod) regulates the passage that siphunculus provides to carry out by reset, reset and regulate one end of siphunculus to screw, to be connected in pedestal side by level, the other end is exposed outside railway ballast, is provided with the limit on the right-right-hand limit positive stop lug boss of original position adjusting screw(rod) in pipe, pedestal is fixed on roadbed railway ballast, by compact heap, by bolt, cylindricality wedge bearing support and sleeper is connected into one.
Wedge self-locking automatic sedimentation compensation arrangement for changeover portion of the present utility model, utilizes the Wedge mechanism with self-locking of 6～12 °, by the trigger action of steel rail spring restoring force, and automatic controlled height, the unsettled amount of compensating sleeper.Specific works principle is as follows: during assembling, first by original position adjusting screw(rod), tapered wedges is adjusted to limit on the left position (being original position), with compact heap, cylindricality wedge bearing support and sleeper are connected into one, make cylindricality wedge bearing support in upper/lower positions simultaneously, contact with tapered wedges.After steel rail laying completes, with special spanner, by reset, regulate siphunculus that original position adjusting screw(rod) is adjusted to limit on the right-right-hand limit position.The frictional force moving right in the time of can only overcoming on its inclined-plane without active force due to the spring on tapered wedges, therefore, tapered wedges keeps limit on the left position (being original position) constant.When train wheel is through out-of-date, the active force that wheel produces rail is pressed onto on railway roadbed via sleeper, cylindricality wedge bearing support, tapered wedges and pedestal, if sedimentation appears in railway roadbed, rail will produce elastic bending deflection downwards.When train wheel leaves, the elastic deformation of rail is recovered, and produces a very large elastic force making progress, and rail drives sleeper to move upward, and makes voided sleeper.Because cylindricality wedge bearing support and sleeper are connected into one, and pedestal is fixed on roadbed, and cylindricality wedge bearing support and pedestal produce relative motion, and cylindricality wedge bearing support departs from tapered wedges.Now, unexpected ineffective power on the inclined-plane of tapered wedges, tapered wedges overcome friction under the pre-compression force effect of spring moves right along dive key, until the inclined-plane of tapered wedges is when contact with the inclined-plane of cylindricality wedge bearing support lower end, tapered wedges is just slack, has just in time compensated the settling amount of railway roadbed.When train wheel is again through out-of-date, the Wedge mechanism forming due to cylindricality wedge bearing support and tapered wedges has self-locking action, downward active force can not change the position of tapered wedges, that is the height of device remains unchanged, the active force that wheel produces rail is still pressed onto on railway roadbed via sleeper, cylindricality wedge bearing support, tapered wedges and pedestal.If now railway roadbed is without sedimentation, the height of device is constant; If now sedimentation appears in railway roadbed, again repeat above-mentioned adjustment process.
Wedge self-locking automatic sedimentation compensation arrangement for changeover portion of the present utility model, have simple in structurely, automatically regulate the features such as reliable operation, can be used on the Ballast track railway roadbed in different line construction transition location, solve the irregularity problem that circuit differential settlement causes.
