Problems solved by technology

[0003] In the existing Chinese Type II sleepers, the spikes are directly fixed on the cement sleepers and cannot be removed. When the spike parts are damaged, only the Type II sleepers can be replaced, which leads to high maintenance costs and inconvenient operation.

Embodiment Construction

[0011] Such as figure 1 As shown, the wooden sleeper for meter rails of the present invention includes a wooden sleeper (10), and the wooden sleeper is connected with a connecting piece for connecting the wooden sleeper and the wooden sleeper spring fastener, and the connecting piece includes a plate Lower backing plate (1), iron backing plate (2), heavy-duty spring washers (3) and screw spikes (4). ), the heavy spring washer (3) is set between the threaded spike (4) and the iron backing plate (2).

[0012] The wooden sleeper of the present invention is suitable for a curved track and a straight track with a gauge of 1000mm and a radius R≥250m. Satisfy driving requirements: the operating speed is 60km / h, and the axle load is 17.5t;

[0013] In actual application, the steel rail (12) is fixed on the iron backing plate (2) of the wooden sleeper of the meter gauge through the wooden sleeper clip fastener (11). Its structure is suitable for UIC54 rail.

Abstract

The invention provides a wood sleeper used for meter-gauge rails. The wood sleeper comprises a wood sleeper body (10) which is connected with connecting pieces used for connecting the wood sleeper with a wood sleeper elastic fastener. Each connecting piece comprises an under-plate bolster (1), an iron bolster (2), heavy spring washers (3) and four screw spikes (4). The under-plate bolster (1) is arranged between the iron bolster (2) and the wood sleeper body (10), and the heavy spring washers (3) are arranged between the screw spikes (4) and the iron bolster (2). The wood sleeper has the advantages that the iron bolster and the wood sleeper body are fastened through the four screw spikes, so that connection is firmer; the iron bolster mainly features in laying pressure on the larger area of the wood sleeper body to prevent the same from being damaged; a 1:4 rain cant is arranged on the iron bolster to guarantee the iron rails to be reasonable; the wood sleeper body and the wood sleeper elastic fastener are well cooperated to meet requirements on security and reliability; the wood sleeper has sufficient strength, rigidity and safety in structure; structure stress and spacing requirements can be met.

Description

technical field [0001] The invention relates to a wooden sleeper for meter rails, belonging to the technical field of transportation. Background technique [0002] In recent years, all countries and countries are vigorously promoting railway construction, but most countries adopt meter-gauge railway systems with a gauge of 1000 mm. The characteristics of many times, using fatigue reliability for design, has been relatively mature in terms of experience and technology. Therefore, the meter-gauge type II wooden sleeper is specially designed with reference to the size of the Chinese type II wooden sleeper. [0003] In the existing Chinese Type II sleepers, the spikes are directly fixed on the cement sleepers and cannot be removed. When the spike parts are damaged, only the Type II sleepers can be replaced, which leads to high maintenance costs and inconvenient operation. Contents of the invention [0004] The purpose of the present invention is to overcome the disad...
