Abstract
A kind of sleeper flush type is without tiny fragments of stone, coal, etc. track switch section of track lateral adjustment device, comprise that bottom is fixed on the steel crab-bolt in concrete support layer, described steel crab-bolt top is provided with cross through hole, in cross through hole, be inserted with horizontal lead screw, the bearing bar that one end of described horizontal lead screw and switch tie bottom arrange is welded and fixed, the other end is connected with steel crab-bolt by adjusting nut, and by regulating adjusting nut to realize the transverse shifting of horizontal lead screw and then to drive switch tie transverse shifting; The utility model is simple in structure, the laterally bearing bar welding of lead screw directly and under switch tie, and more efficiently convenient in the time carrying out lateral adjustments, laterally lead screw is provided with graduation mark, can regulate accurately section of track lateral length.
Description
Technical field
The utility model relates to a kind of lateral adjustment device, relates to specifically a kind of sleeper flush type without tiny fragments of stone, coal, etc. track switch section of track lateral adjustment device.
Background technology
No. 18 sleeper embedded type turnouts, 141 of total length 69m, switch tie quantity, when track switch lateral orientation Coordinate Adjusting, need horizontal fine control rod to adjust the lateral coordinates of the track switch section of track, first steel crab-bolt is vertically inserted in the supporting bed concrete anchor keyhole of switch tie both sides, adopted high-strength mortar by its anchoring; Laterally lead screw is through at crab-bolt below, and welds connection with the reinforcing bar of switch tie bottom; In the lead screw of band steel both sides, there are respectively two screws to fix.Nowadays No. 18 sleeper embedded type turnout accurate adjustment standard-requireds of special line for passenger trains are high, adopted one section of reinforcing bar directly the mode of switch tie bottom reinforcement bars and lead screw weldering connection can not have been adapted to the needs of current high-speed switch development in the past, subject matter is that accurate adjustment efficiency is low and solid with template not prison welding, 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 lateral adjustment device, and it is simple in structure, can efficiently complete easily section of track lateral adjustments.
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 lateral adjustment device, comprise that bottom is fixed on the steel crab-bolt in concrete support layer, described steel crab-bolt top is provided with cross through hole, in cross through hole, be inserted with horizontal lead screw, the bearing bar that one end of described horizontal lead screw and switch tie bottom arrange is welded and fixed, the other end is connected with steel crab-bolt by adjusting nut, and by regulating adjusting nut to realize the transverse shifting of horizontal lead screw and then to drive switch tie transverse shifting.
Described steel crab-bolt top is square.
Described steel crab-bolt bottom is anchored in concrete support layer by high-strength mortar.
Described horizontal lead screw is provided with the graduation mark that regulates length for identifying.
The beneficial effects of the utility model: the utility model is simple in structure, the laterally bearing bar welding of lead screw directly and under switch tie, more efficiently convenient in the time carrying out lateral adjustments, laterally lead screw is provided with graduation mark, can regulate accurately section of track lateral length.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Mark in figure: 1, concrete support layer, 2, steel crab-bolt, 3, cross through hole, 4, horizontal lead screw, 5, switch tie, 6, bearing bar.
Detailed description of the invention
As shown in the figure, a kind of sleeper flush type is without tiny fragments of stone, coal, etc. track switch section of track lateral adjustment device, comprise that bottom is fixed on the steel crab-bolt 2 in concrete support layer 1, described steel crab-bolt 2 tops are provided with cross through hole 3, in cross through hole 3, be inserted with horizontal lead screw 4, the bearing bar 6 that one end of described horizontal lead screw 4 and switch tie 5 bottoms arrange is welded and fixed, the other end is connected with steel crab-bolt 2 by adjusting nut, and by regulating adjusting nut to realize the transverse shifting of horizontal lead screw 4 and then to drive switch tie 5 transverse shiftings, described steel crab-bolt 2 tops are square, described steel crab-bolt 2 bottoms are anchored in concrete support layer 1 by high-strength mortar, described horizontal lead screw 4 is provided with the graduation mark that regulates length for identifying.
The utility model is simple in structure, the laterally bearing bar welding of lead screw directly and under switch tie, and more efficiently convenient in the time carrying out lateral adjustments, laterally lead screw is provided with graduation mark, can regulate accurately section of track lateral length.
