Detailed Description
The present invention will be described in detail with reference to the accompanying drawings 1-4 and the detailed description thereof.
A novel single-rail turnout locking device comprises a joint rail beam I1, a joint rail beam II 2, a trolley 3, an electric push rod 4 and a locking roller 7, wherein two ends of the joint rail beam II 2 are arranged above the trolley 3; a locking groove 5 is arranged on the outer end face of the trolley 3; the electric push rod 4 is horizontally fixed on a turnout bottom plate 6 on the outer side of the trolley 3, the locking idler wheel 7 is hinged on a locking shaft 9 at the front end of the electric push rod 4, and the electric push rod 4 and the locking idler wheel 7 are both positioned below the joint track beam I1; the electric push rod 4 drives the locking roller 7 to enter or exit the locking groove 5 to complete locking or unlocking of the trolley 3.
The tail end of the electric push rod 4 is hinged to the base 8, the base 8 is fixed to the turnout bottom plate 6, the locking idler wheel 7 is installed on the top end of the locking shaft 9, the lower end of the locking shaft 9 is hinged to the base 8, and the front end of the electric push rod 4 is hinged to the middle of the locking shaft 9.
At least two locking grooves 5 are arranged on the outer end face of the trolley 3, and the locking grooves 5 are fixed on the outer end face of the trolley 3 through welding or screws. The quantity and the position of locking groove 5 are confirmed according to the switch needs of switch, realize joint track roof beam II 2 and switch horizontal locking and unblock when different positions.
Preferably, the locking shaft 9 is of an inverted T-shaped structure, a pair of lugs 10 is fixed on the base 8, and the lower end of the locking shaft 9 is hinged between the lugs 10.
The working principle is as follows: the T-shaped locking shaft 9 is rotated by controlling the extension and retraction of the electric push rod 4; the locking roller 7 is driven to rotate, when the electric push rod extends, the locking roller rotates clockwise to enter the locking groove 5, and transverse locking is achieved; when the electric push rod is contracted, the locking roller rotates anticlockwise to withdraw from the locking groove 5, and transverse unlocking is achieved.
The utility model discloses arrange according to the horizontal direction, compare with longitudinal arrangement, reduced occuping of direction of height space by a wide margin, and length direction (electric putter tail end to the distance of locking gyro wheel) obviously is greater than direction of height (base to electric putter's farthest distance) size, and then makes the platform truck height reduce by a wide margin, and the track roof beam focus also reduces thereupon, and orbital antidumping performance promotes. Under the same condition, under the premise of meeting the anti-overturning performance of the track, the track width of the trolley can be reduced, so that the transverse sizes of the two sides of the turnout beam system are reduced, and the transverse occupied area and the occupied space of the turnout system are reduced. The optimization of the integral structure of the joint type track is realized, and the adaptability of the turnout system is improved.
The above-mentioned embodiments are merely preferred embodiments of the present invention, and not intended to limit the scope of the present invention, so that all equivalent changes made by the contents of the claims of the present invention should be included in the scope of the claims of the present invention.
