Description

Technical Field

[0001] The present application relates to the technical field of railway construction accessories, and in particular to a railway construction temporary beam rail fastener. Background Art

[0002] Rail fasteners are important components on tracks that connect rails to sleepers (or other types of rail foundations), also known as intermediate connecting parts. Their main function is to secure the rails, preventing them from moving vertically or horizontally relative to the sleepers, and maintaining track gauge.

[0003] Rail fasteners typically consist of two parts: clamps and rail pads. Clamps primarily secure the rails, restricting their forward, backward, left, right, and upward / downward movement, thereby maintaining the rail's geometric dimensions. Common clamps include spring clips and plates. Spring clip fasteners are widely used in modern railways due to their rational structure, stable clamping force, and excellent elasticity. Rail pads primarily provide sufficient elasticity for the track and assist clamps in securing the rails. Rail pads are typically made of materials such as rubber pads and plastic pads, which exhibit excellent elasticity and durability.

[0004] In the prior art, when a railway vehicle passes at high speed, the vibration it generates will directly act on the rails and their fasteners, which can easily cause the nuts of the fasteners to loosen. At the same time, due to the concentrated clamping stress between the clamping parts and the rails, cracks can easily form at the clamping points of the clamping parts, leading to breakage. Utility Model Content

[0005] In order to solve or partially solve the problems existing in the relevant technology, the present application provides a railway construction temporary beam rail fastener, which can effectively prevent the nuts and washers from loosening, ensure that the fastener can maintain the fastening force for a long time, extend the service life of the entire fastener system, and enhance its fatigue resistance.

[0006] The present application provides a railway construction temporary beam rail fastener, comprising an embedded bolt 1, a clip plate 2, and a clip plate base 3; the embedded bolt 1 is bent, and the lower part of the embedded bolt 1 is embedded in the sleeper, and the embedded bolt 1 passes through the clip plate 2, and the two ends of the clip plate 2 are tilted upward. The bottom of one end of the clip plate 2 abuts against the clip plate base 3, and the other end is fixedly connected with a claw 8. The end of the bottom surface of the clip plate 2 is fixedly connected with a protrusion 7, and a groove 4 is provided at the end of the top surface of the clip plate 2. The top surface of the clip plate 2 abuts against an elastic bar 5, and one end of the elastic bar 5 is embedded in the groove 4. The outer surface of the middle section of the elastic bar 5 is provided with an anti-slip groove 6. A washer 9 is sleeved on the embedded bolt 1, and the washer 9 abuts against the top of the elastic bar 5. The bottom of the washer 9 is provided with a plurality of tooth grooves 10, which engage with the corresponding anti-slip grooves 6. The top of the washer 9 is fixedly connected with a nut 11, and the nut 11 is threadedly connected to the embedded bolt 1.

[0007] Optionally, in some solutions, the bending angle of the embedded bolt 1 is 90 degrees, and the buckle plate 2 is made of rubber.

[0008] Optionally, in some solutions, the shape of the elastic bar 5 is "M"-shaped, and the material of the elastic bar 5 is spring steel.

[0009] Optionally, in some solutions, the middle portion of the elastic bar 5 is arched upward, and both ends are pressed downward.

[0010] Optionally, in some embodiments, the tooth grooves 10 are arranged in a circumferential array about the axis of the washer 9 .

[0011] The technical solution provided by this application may have the following beneficial effects:

[0012] The present invention adopts the coordinated arrangement of the spring bar, anti-slip grooves, buckle claws, washers, tooth grooves, and nuts. The outer surface of the middle section of the spring bar is provided with anti-slip grooves, and a plurality of tooth grooves are designed at the bottom of the washer of the nut. When the nut is tightened, the tooth grooves at the bottom of the washer and the anti-slip grooves of the middle section of the spring bar are in continuous contact until the nut is tightened and the spring bar is compressed. At this time, the design of the anti-slip grooves and tooth grooves increases the friction between the spring bar and the washer, which can effectively prevent the nut and washer from loosening, ensure that the fastener can maintain the buckling and tightening force for a long time, extend the service life of the entire fastener system, and enhance its fatigue resistance.

[0013] The design of the claw in this application increases the clamping surface of the clamping plate with the rail, prevents stress concentration, ensures that the clamping plate is evenly stressed, reduces deformation or cracks in the clamping plate caused by excessive local pressure, thereby increasing the service life of the clamping plate and the stability of the overall structure, preventing the clamping plate from cracking and breaking, and increasing its service life.

[0026] In response to the above problems, an embodiment of the present application provides a railway construction temporary beam rail fastener, which can effectively prevent the nut and washer from loosening, ensure that the fastener can maintain the fastening force for a long time, extend the service life of the entire fastener system, and enhance its fatigue resistance.

[0027] The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0028] See also Figure 1-4 The railway construction temporary beam rail fastener includes an embedded bolt 1, a gusset plate 2, and a gusset plate base 3; the embedded bolt 1 is bent, and the lower part of the embedded bolt 1 is embedded in the sleeper, and the embedded bolt 1 passes through the gusset plate 2, and the two ends of the gusset plate 2 are tilted upward. The bottom of one end of the gusset plate 2 abuts against the gusset plate base 3, and the other end is fixedly connected with a claw 8. The end of the bottom surface of the gusset plate 2 is fixedly connected with a protrusion 7. A groove 4 is provided at the end of the top surface of the gusset plate 2, and the top surface of the gusset plate 2 abuts against an elastic bar 5. One end of the elastic bar 5 is embedded in the groove 4, and the outer surface of the middle section of the elastic bar 5 is provided with an anti-slip groove 6. A washer 9 is sleeved on the embedded bolt 1, and the washer 9 abuts against the top of the elastic bar 5. The bottom of the washer 9 is provided with a plurality of tooth grooves 10, which mesh with the corresponding anti-slip grooves 6. The top of the washer 9 is fixedly connected with a nut 11, which is threadedly connected to the embedded bolt 1.

[0029] When working, a single set of fasteners buckles the edge of the lower part of the rail, and two sets of fasteners cooperate to buckle a single rail. The rail is centered, and the buckle plate base 3 is placed on the slope of the sleeper. The lower part of the embedded bolt 1 is embedded in the concrete sleeper. The buckle plate 2 is put on along the embedded bolt 1, and the protrusion 7 of the buckle plate 2 abuts the end face of the lower part of the rail. The bottom surface of the end of the buckle plate 2 and the buckle claw 8 are buckled on the end of the lower part of the rail. The bottom of the other end of the buckle plate 2 is pressed on the buckle plate base 3, and then the elastic bar 5 is put on. One end of the elastic bar 5 is embedded in the groove 4, and then the washer 9 and the nut 11 are installed, and the nut 11 is tightened. The tooth groove 10 at the bottom of the washer 9 is in continuous contact with the anti-slip groove 6 in the middle section of the elastic bar 5, and a contact sound is continuously made, which tightens the elastic bar 5 and tightens the nut 11, thereby completing the installation of the single set of fasteners, and then install the fastener on the other side.

[0030] The outer surface of the middle section of the elastic bar 5 is provided with anti-slip grooves 6, and a number of tooth grooves 10 are designed at the bottom of the washer 9 of the nut 11. When the nut 11 is tightened, the tooth grooves 10 at the bottom of the washer 9 are in continuous contact with the anti-slip grooves 6 in the middle section of the elastic bar 5 until the nut 11 is tightened and the elastic bar 5 is compressed. At this time, the design of the anti-slip grooves 6 and the tooth grooves 10 makes the friction between the elastic bar 5 and the washer 9 large, which can effectively prevent the nut 11 and the washer 9 from loosening, ensuring that the fastener can maintain the fastening force for a long time, extending the service life of the entire fastener system and enhancing its fatigue resistance.

[0031] In some embodiments, the bending angle of the embedded bolt 1 is 90 degrees, and the buckle plate 2 is made of rubber; the shape of the elastic bar 5 is "M" shaped, and the material of the elastic bar 5 is spring steel; the tooth groove 10 is a circular array about the axis of the washer 9.

[0032] During operation, the gusset plate 2, the protrusion 7 and the claw 8 are integrally formed, and the bending angle of the embedded bolt 1 is 90 degrees, which improves the stability of the embedded bolt 1. The design of the claw 8 increases the pressing surface of the gusset plate 2 with the rail to prevent stress concentration, ensure that the gusset plate 2 is evenly stressed, and reduce deformation or cracks of the gusset plate caused by excessive local pressure, thereby improving the service life of the gusset plate and the stability of the overall structure, preventing the gusset plate 2 from cracking and breaking, and improving its service life.

[0033] In some embodiments, the middle portion of the elastic bar 5 is arched upward, and both ends are pressed downward.

[0034] During operation, the middle part of the spring bar 5 arches upward and the two ends press down, which can ensure that the tooth groove 10 on the washer 9 fits tightly with the anti-slip groove 6 in the middle of the spring bar 5, ensuring that the friction between the spring bar 5 and the washer 9 is large enough, which can effectively prevent the nut 11 and the washer 9 from loosening, and ensure that the fastener can maintain the fastening force for a long time.
