Track automatic locking press-board device

Abstract

The orbital automatic locking clamp installment includes the clamp, the set bolt and the automatic positioning lock mechanism. The automatic positioning lock mechanism including the spring attachment adjustment board, moving slide board, two spring localization threaded pipe, the conical roof block and two locking wedge iron, front end the clamp in the both sides bottom surface has corresponds start lock trough separately, two locking wedge iron establishes in the lock trough, the spring attachment adjustment board fixes on clamp's top, moving slide board stand on clamp's top, may under spring's function guide by the guiding mechanism,on the spring attachment adjustment board's top goes forward moves; The conical roof block fixes in a support's lower extremity, this support's upper extreme fixes on the motion slide board. This invention's structure is simple, safe reliable, can suppress effectively the railway rail, not only save the maintenance expense but also reduce the accident occurrence greatly.

Description

(1) Technical field [0001] The invention relates to a track automatic locking pressure plate for fixing a steel rail on a concrete sleeper. (2) Background technology [0002] Crane is a kind of load-carrying tool commonly used in factory workshops. At present, steel rails are fixed by a rigid method. As the application number is: 9200549, and the Chinese patent of CN2044994 with the announcement number discloses a pressure plate type rail fixer, which consists of backing plates , composed of anchor nails, pressure plates and pressure plate pins. The backing plate and anchor nails are prefabricated on the sleeper, and then the pressure plate and pressure plate pins are installed in sequence. The pressure plate presses the lower edge of the rail, and the pressure plate pins are used to prevent the pressure plate from moving horizontally. The whole device is fixed by ground nails. Since this kind of rail holder does not have the function of cushioning and pressing, it is easy t...

[0002] Crane is a kind of load-carrying tool commonly used in factory workshops. At present, steel rails are fixed by a rigid method. As the application number is: 9200549, and the Chinese patent of CN2044994 with the announcement number discloses a pressure plate type rail fixer, which consists of backing plates , composed of anchor nails, pressure plates and pressure plate pins. The backing plate and anchor nails are prefabricated on the sleeper, and then the pressure plate and pressure plate pins are installed in sequence. The pressure plate presses the lower edge of the rail, and the pressure plate pins are used to prevent the pressure plate from moving horizontally. The whole device is fixed by ground nails. Since this kind of rail holder does not have the function of cushioning and pressing, it is easy to cause rail gnawing and loosening, which will not only increase the maintenance cost, but also easily cause safety accidents
