Abstract

The utility model is a slot type railway sleeper as a railway sleeper for track transport. Both ends of the railway sleeper are provided with a pair of T-shape slots corresponding with each other, at bottom of which horizon slots are disposed, with T-shape bolts arranged into the T-shape slots in the manner that the bolts head disposed in the horizon slots, covering a pressing plate, and a gasket on the T-shape bolts, and screwing tight the nut to press the pressing plate on the track firmly. The utility model can rapidly replace a damage compoment when the pressing plate or the bolt is damaged to improve the service life of the railway sleeper and reduce a transport cost without effecting continuous use of the railway sleeper.

Description

The open flume type sleeper

Technical field:

The utility model belongs to the sleeper in the rail transport, mainly is applicable to the rail transport of mine and factory.

Technical background:

At present, sleeper in the rail transport, consumption is big, as the Chinese patent 85201943.2 rail meter sleeper of giving, though widely the mine rail transport point is used, but also there is very big shortcoming, owing to rail clip is fixed in the sleeper of cement concrete, in case any rail clip damages, whole sleeper will be scrapped, again more renew sleeper, not only waste time and energy, and increased cost of transportation.

Summary of the invention:

The utility model proposes a kind of easy-to-mount open flume type sleeper in order to overcome the shortcoming of background technology, after the fastening devices of track is damaged, only needs to change damaged part and gets final product, and need not change whole sleeper.

The utility model is made up of sleeper, tommyhead bolt, nut, packing ring, pressing plate, dividing plate and the sprue of trough of belt, two ends at sleeper, a pair of groove shape space is in correspondence with each other respectively arranged, groove shape space is made up of cannelure, transverse groove and level trough, cannelure becomes T shape to be communicated with transverse groove, level trough is positioned at the bottom of cannelure and transverse groove and interconnects; Square locating piece is arranged in the middle of the screw rod of tommyhead bolt.

The utility model is compared with background technology, its advantage:

(1) cost of production is low, and the use steel have only half of background technology;

(2) maintenance of sleeper is little, has reduced working strength of workers;

(3) easy accessibility when pressing plate or bolt failure, as long as change damaged part, does not influence sleeper, has improved the application life of sleeper, has reduced cost of transportation.
