Description
Technical field
The utility model relates to a kind of arrangement for adjusting height, relates to specifically a kind of sleeper flush type without tiny fragments of stone, coal, etc. track switch section of track vertical height adjusting device.
Background technology
No. 18 sleeper embedded type turnouts, 141 of total length 69m, switch tie quantity, during track switch height fine-adjustment, need vertical adjustment bar to adjust the height of the track switch section of track, general vertical bar passes and holds on concrete bearing layer from a switch tie two side holes bolt, utilizes one, two screws to be threaded onto switch tie top, another screw is spun on the height that the track switch section of track is adjusted in switch tie bottom simultaneously.But because No. 18 sleeper embedded type turnout supporting bed concrete grades of special line for passenger trains mostly are C15 type, intensity is lower now.When track switch section of track Height Adjustment, vertical height adjusting rod uses and has some inconvenience, is mainly when Height Adjustment, and adjusting rod is difficult to the track switch section of track to reach the Height Adjustment of effective adjustment, reason is to adjust rod member while heightening easily to pierce in supporting bed concrete, and result of use is undesirable.
Utility model content
The utility model, in order to solve the problems of the technologies described above, provides a kind of sleeper flush type without tiny fragments of stone, coal, etc. track switch section of track vertical height adjusting device, and it is simple in structure, can efficiently complete easily the adjusting of section of track vertical height.
The technical scheme that the utility model adopts is: a kind of sleeper flush type is without tiny fragments of stone, coal, etc. track switch section of track vertical height adjusting device, comprise the vertical threaded rod that vertically passes switch tie upper and lower surface, this vertical threaded rod is fixedly connected with the upper and lower surface of switch tie by nut, described vertical threaded rod comprises the outer bar of screw thread, through bar and two ends in the screw thread of switch tie, be separately positioned on the adjusting threaded rod in bar in the outer bar of screw thread and screw thread, described adjusting threaded rod is threaded with bar in screw thread and the outer bar of screw thread respectively, on its external surface, be also provided with a sleeve, the inner surface of this sleeve and adjusting threaded rod threaded engagement, and on sleeve, be also provided with the handle of its rotation of drive, handle regulates threaded rod to move up and down by driving sleeve rotating and then driving, the outer bar of described screw thread bottom is provided with the firm pad that is placed on concrete support layer to increase the contact area of the outer bar of screw thread and concrete support layer, and then reduce the pressure between itself and concrete support layer.
In described screw thread, bar stretches out switch tie 2～3cm.
Described adjusting threaded rod is provided with the graduation mark that regulates height for identifying.
The beneficial effects of the utility model: the utility model is simple in structure, regulate threaded rod to be provided with graduation mark, can regulate accurately section of track vertical height, the utility model regulates the height of switch tie by sleeve with regulating being threaded of threaded rod, adjusting personnel can complete highly and regulate without the instrument of carrying, both reduced the working strength that regulates personnel, increased again operating efficiency, the utility model is provided with for supporting the steel plate washer of vertical threaded rod on concrete support layer, effectively increased the contact area of vertical threaded rod and concrete support layer, reduced the pressure between vertical threaded rod and concrete support layer, avoided that excessive thereby to cause concrete support layer to break to make switch tie height to regulate inaccurate because bearing pressure because of concrete support layer.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Mark in figure: 1, switch tie, 2, vertical threaded rod, 3, nut, 4, sleeve, 5, the outer bar of screw thread, 6, bar in screw thread, 7, regulate threaded rod, 8, concrete support layer, 9, steel plate washer, 10, handle.
