Description

Technical Field

[0001] The utility model belongs to the technical field of railway track facilities, in particular to a railway track pad. Background Art

[0002] Railway pads are used in rail fastener assemblies under rails for buffering or electrical insulation. Such railway pads are generally made of iron and are prone to rust. When the parts on the pads lose their elasticity due to extrusion, the entire pad needs to be replaced, which wastes resources and reduces the working efficiency of the train.

[0003] Among them, after searching, it was found that there was an application number CN202020053537.5, which disclosed a railway track pad, including a pad body, the surface of the pad body is an installation surface, two parallel mounting strips are fixed on the installation surface, the mounting strip is provided with a dovetail groove, and the space between the two mounting strips is an installation channel for installing the rails. The mounting strip has a dovetail groove, which makes it easy to screw in the bolts during installation and makes the installation more secure. The fixing holes connected by sliding grooves can adjust the fixed position of the fixing holes, which has the advantage of being easy to use.

[0004] However, after research, it was found that the following problems were not solved by the device: when installing the pad, the staff needed to manually align it, which wasted time and reduced the staff's work efficiency. At the same time, when the parts on the pad lost their elasticity due to extrusion, the entire pad needed to be replaced, which not only wasted resources but also reduced the work efficiency of the train. Therefore, a new device was provided to solve this problem. Utility Model Content

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] In the utility model:

[0019] Reference Figure 1-4 A railway track pad comprises a sleeper 1, wherein both sides of the sleeper 1 are symmetrically embedded with embedded sleeves 101, and the embedded sleeves 101 are internally embedded with spiral spikes 201, an insulating buffer pad 102 is installed above the sleeper 1, an iron pad 2 is installed above the insulating buffer pad 102, and both sides of the iron pad 2 and the insulating buffer pad 102 are symmetrically provided with embedded sleeve holes;

[0020] In this embodiment, a replacement mechanism that can be easily replaced is installed above the iron pad 2, and the replacement mechanism includes a T-bolt 202, a W-shaped spring bar 203, a spring block 204, an insulating block 205, a rail 206 and a rail pad 207. The iron pad 2 is made of ductile iron, and T-bolts 202 are symmetrically installed on both sides of the upper side of the iron pad 2. A gauge baffle seat 208 is symmetrically arranged between the T-bolts 202 and the embedded sleeve 101 on both sides of the upper side of the iron pad 2, and a W-shaped spring bar 203 is installed above the gauge baffle seat 208. 03, the W-shaped spring bar 203 and the T-shaped bolt 202 are connected through, and there is a convex block near the spring block 204 below the W-shaped spring bar 203, and the convex block is pressed on the spring block 204, which can fix the spring block 204 to prevent the spring block 204 from sliding out when subjected to force. A rail pad 207 is installed in the middle of the upper part of the iron pad 2, and a steel rail 206 is arranged above the rail pad 207. The spring blocks 204 are symmetrically installed on both sides of the upper part of the iron pad 2 between the T-shaped bolt 202 and the rail pad 207, and a groove is arranged on one side of the spring block 204. At the same time, a convex block 204 is provided at the bottom, and there are at least two convex blocks at the bottom of the convex block 204, and the convex blocks at the bottom of the convex block 204 fit with the grooves on both sides above the iron pad 2, and the convex blocks at the bottom of the convex block 204 are inclined at an angle of 80° to the bottom edge of the convex block 204. Insulating blocks 205 are symmetrically installed between the rails 206 and the convex blocks 204 on both sides above the rails 206, and the convex blocks 205 on one side fit with the grooves of the convex block 204. The T-bolts 202 and the rail pads on both sides above the iron pad 2 A groove is provided between the plates 207. Since the W-shaped spring bar 203 and the T-shaped bolt 202 are connected through, the T-shaped bolt 202 can fasten the W-shaped spring bar 203. After the spring block 204 is squeezed for a long time, it is easy to lose its elasticity, which reduces the track support. The spring block 204 can be disassembled to facilitate replacement and also improve the track support. The rail pad 207 can raise the rail 206 and prevent the rail 206 from contacting the iron pad 2. The insulating block 205 also prevents the rail 206 from contacting the iron pad 2.

[0021] In this embodiment, a spring washer 2011 is installed under the spiral spike 201, and a flat washer 2012 is symmetrically installed between the spring washer 2011 and the iron pad 2. The spring washer 2011 can reduce shock and the flat washer 2012 can adjust the height of the spiral spike 201. The spiral spike 201 passes through the embedded sleeve holes symmetrically installed on both sides of the iron pad 2 and the insulating buffer pad 102 and is fixed in the sleeper 1. During installation, the iron pad 2 and the insulating buffer pad 102 can be directly inserted into the embedded sleeve 101, and there is no need to spend time on alignment, which saves staff time and also improves the work efficiency of the train.

[0022] Working principle: First, the staff inserts the iron pad 2 and the insulating buffer pad 102 from the embedded sleeve 101, and there is no need to spend time aligning the iron pad and the rail pad with the embedded sleeve, which saves the staff's time and improves the staff's work efficiency. Then, the flat pad 2012 is installed on the embedded sleeve 101. The flat pad 2012 can adjust the spiral spike 201, and then the spring washer 2011 is installed on the flat pad 2012. Later, the spiral spike 201 is embedded into the embedded sleeve 101 and the iron pad 2 and the insulating buffer pad 102 are fixed to the sleeper 1, and then the rail pad 207 is installed in the middle of the iron pad 2. The rail pad 207 has the functions of raising the rail 206 and preventing the rail 206 from contacting the iron pad 2. Because the bulge at the bottom of the block 204 fits with the grooves on both sides above the iron pad 2, and the bottom of the block 204 The inclination angle between the protrusion at the top and the bottom edge of the spring block 204 is 80°, so the spring block 204 needs to be installed obliquely. After the spring block 204 is squeezed for a long time, it is easy to lose its elasticity, which reduces the track support. The spring block 204 can be disassembled, which is convenient for replacement and can also improve the track support. Then the rail 206 is installed, and then the insulating block 205 is installed. The insulating block 205 also prevents the rail 206 from contacting the iron pad 2. Finally, the W-shaped spring bar 203 and the T-bolt 202 are connected through, so the T-bolt 202 can tighten the W-shaped spring bar 203 and will not let the W-shaped spring bar 203 generate left and right forces, which is more stable. Since there is a protrusion near the spring block 204 below the W-shaped spring bar 203, and the protrusion is pressed on the spring block 204, the W-shaped spring bar 203 can fix the spring block 204 to prevent the spring block 204 from sliding out when subjected to force.

[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
