Description

Technical Field

[0001] The utility model relates to the technical field of rail installation, in particular to a guardrail adjusting piece and a guardrail pad structure. Background Art

[0002] A turnout is a track device that allows trains to switch from one track to another. Guardrails are installed at turnouts to prevent wheels from striking the tip of the frog rail, climbing onto the rail surface, or entering the opposite direction of the frog, potentially causing derailment. Because wheels passing through the guardrail flange groove exert repeated lateral forces on the guardrail, guardrail pads are typically used to support the guardrail and prevent lateral deflection.

[0003] For example, patent CN 212611715 U discloses an adjustable guardrail pad structure used on a wooden sleeper line, which includes a pad on which a main rail, a rail pressure iron and a rail support are arranged in sequence. One end of the rail pressure iron presses the lower side end of the main rail, and a guardrail is arranged on the rail pressure iron. Bolts pass through the guardrail and the rail support in sequence and are fixed by nuts. A U-shaped adjustment plate can be optionally provided between the guardrail and the rail support, and the bolts pass through the U-shaped opening of the U-shaped adjustment plate to reduce maintenance costs. The structure is easy to operate.

[0004] However, the adjustment plate in this patent adopts a U-shaped opening. When the guardrail bolt is loose, the track is easily vibrated by the impact of the wheels, which can cause the adjustment plate to jump upward and protrude from the guardrail and be unable to fall down, posing a driving safety hazard. Utility Model Content

[0005] The purpose of the utility model is to overcome the above-mentioned technical deficiencies and propose a guardrail adjustment piece and guardrail pad structure to solve the technical problem in the prior art that the adjustment piece adopts a U-shaped opening, and when the guardrail bolt is loose, the track is easily vibrated by the impact of the wheel, causing the adjustment piece to jump upward and protrude from the guardrail and be unable to fall down, posing a potential driving safety hazard.

[0006] In order to achieve the above technical purpose, the present invention adopts the following technical solutions:

[0007] In a first aspect, the present invention provides a guard rail adjustment piece, comprising:

[0008] The adjusting piece body is provided with an avoidance groove and a limiting groove, one end of the avoidance groove is open, the limiting groove is connected to the other end of the avoidance groove, the limiting groove extends in a direction away from the avoidance groove and is arranged at an angle to the avoidance groove; and

[0009] The counterweight block is arranged on the adjustment piece body. When a guard rail bolt of a guard rail pad structure is passed through the limit groove, it can drive the adjustment piece body to maintain a position where the extension direction of the limit groove coincides with the horizontal direction, and make the limit groove above the avoidance groove.

[0010] In some embodiments, the adjustment piece body has a counterweight end and a main body end located at opposite ends, the avoidance groove is formed on the side of the adjustment piece body close to the counterweight end, the limit groove is located on the side of the avoidance groove close to the main body end, and is connected to the upper end of the avoidance groove, and its extension direction is consistent with the layout direction of the counterweight end and the main body end, and the counterweight block is arranged at the counterweight end.

[0011] In some embodiments, the counterweight block is integrally connected to the adjustment piece body, is located at the counterweight end, and extends in a direction away from the body end.

[0012] In some embodiments, the guard rail adjustment piece further includes an anti-slip structure, which is provided on the adjustment piece body and is used to limit the movement of the adjustment piece body relative to the bolt along the direction from the avoidance groove to the limit groove.

[0013] In some embodiments, the anti-slip structure includes an anti-slip elastic sheet, one end of which is connected to the side wall of the limiting groove, and the other end of which is spaced apart from the other side wall of the limiting groove.

[0014] In some embodiments, the side wall of the limiting groove is provided with an installation groove, one end of the anti-slip spring is connected to the bottom wall of the installation groove and is spaced apart from the side wall of the installation groove, and the other end extends from the installation groove into the limiting groove.

[0015] In some embodiments, the anti-dropping elastic piece is provided with a rubber sleeve on one end thereof extending from the mounting slot into the limiting slot; and / or,

[0016] An end of the anti-dropping elastic piece extending from the mounting groove into the limiting groove is provided with an arc surface, and an extending direction of the arc surface is consistent with an extending direction of the limiting groove.

[0017] In some embodiments, the mounting grooves are provided in two groups, and the two groups of mounting grooves are located on two opposite side walls of the limiting groove;

[0018] The anti-slip elastic sheets are provided in two groups, and the two groups of anti-slip elastic sheets are respectively arranged in the two groups of mounting grooves, and the two groups of anti-slip elastic sheets are spaced apart at one end located in the limiting groove.

[0019] In some embodiments, the anti-slip structure further includes a magnetic sheet, which is disposed on the adjustment sheet body and is used to be magnetically attracted to the rail support of the guardrail pad structure.

[0020] In a second aspect, the present invention further provides a guard rail pad structure, comprising a guard rail adjustment piece as described in any one of the above items.

[0021] Compared to the prior art, the guardrail adjustment plate provided by the present invention has a main body of the adjustment plate, balanced by a counterweight, that allows the limiting groove to be positioned horizontally and above the avoidance groove. Therefore, when the guardrail bolt loosens, the limiting groove remains horizontal due to the center of gravity of the guardrail adjustment plate. Thus, when the track vibrates, the sidewalls of the limiting groove are blocked by the guardrail bolt and prevent it from moving upward, effectively preventing the guardrail adjustment plate from moving above the guardrail and eliminating driving safety hazards. Simultaneously, the avoidance groove and the limiting groove are arranged at an angle, which can also prevent the guardrail bolt from accidentally disengaging, thereby ensuring the installation stability of the guardrail adjustment plate. Furthermore, when assembling the guardrail adjustment plate, the opening of the avoidance groove is first aligned with the guardrail bolt, and the main body of the adjustment plate is then lowered so that the guardrail bolt enters the limiting groove from the avoidance groove. The main body of the adjustment plate is then moved again so that the guardrail bolt enters the limiting groove at the end away from the avoidance groove, and the main body of the adjustment plate is then loosened. At this time, the main body of the adjustment piece is balanced by the counterweight block, the limit slot is placed in the horizontal direction, and is above the avoidance slot. In this way, the assembly can be completed by tightening the nut on the guardrail bolt. The operator does not need to manually adjust the adjustment piece, which improves the convenience of assembly.

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] In order to solve the technical problem in the prior art that when the guardrail bolts are loosened, the adjusting piece adopts a U-shaped opening, and the track is easily vibrated by the impact of the wheels, causing the adjusting piece to jump upward and protrude from the guardrail and then be unable to fall down, posing a driving safety hazard, the utility model provides a guardrail adjusting piece, which can effectively prevent the guardrail adjusting piece from jumping above the guardrail, eliminating the driving safety hazard.

[0029] It should be noted that the guard rail adjustment piece described in the present invention is used for but not limited to guard rail pad structures, etc. For the convenience of explanation, in the present invention, only the guard rail adjustment piece applied to the guard rail pad structure is used as an example for explanation. The principle of applying the guard rail adjustment piece to other types of equipment is essentially the same as the principle applied to the guard rail pad structure, and will not be repeated here.

[0030] See also Figure 1 , Figure 1 This is a structural schematic diagram of a guardrail adjustment piece in an embodiment of the present invention, wherein the guardrail adjustment piece includes an adjustment piece body 1 and a counterweight block 2; the adjustment piece body 1 is provided with an avoidance groove 1a and a limit groove 1b, one end of the avoidance groove 1a is open, and the limit groove 1b end is connected to the other end of the avoidance groove 1a, and extends in a direction away from the avoidance groove 1a, and is arranged at an angle to the avoidance groove 1a; the counterweight block 2 is provided on the adjustment piece body 1, and when a guardrail bolt with a guardrail pad structure is passed through the limit groove 1b, it can drive the adjustment piece body 1 to maintain a position where the extension direction of the limit groove 1b coincides with the horizontal direction, and makes the limit groove 1b above the avoidance groove 1a.

[0031] In the guardrail adjustment plate provided by the present invention, the adjustment plate body 1, under the balance of the counterweight block 2, can position the limit slot 1b in a horizontal direction and above the avoidance slot 1a. Therefore, when the guardrail bolt is loosened, the limit slot 1b remains horizontal under the action of the center of gravity of the guardrail adjustment plate. In this way, when the track vibrates, the side wall of the limit slot 1b will be blocked by the guardrail bolt and will not move upward, effectively preventing the guardrail adjustment plate from moving above the guardrail and eliminating driving safety hazards. At the same time, the avoidance slot 1a and the limit slot 1b are set at an angle, which can also prevent the guardrail bolt from accidentally detaching, thereby ensuring the installation stability of the guardrail adjustment plate. In addition, when assembling the guardrail adjustment plate, first align the opening of the avoidance slot 1a with the guardrail bolt, then move the adjustment plate body 1 downward so that the guardrail bolt enters the limit slot 1b from the avoidance slot 1a, and then loosen the adjustment plate body 1. At this time, the adjusting piece body 1 is balanced by the counterweight block 2, and the limit groove 1b is placed in the horizontal direction and above the avoidance groove 1a. In this way, the assembly can be completed by tightening the nut on the guardrail bolt. The operator does not need to manually adjust the adjusting piece, which improves the convenience of assembly.

[0032] It should be noted that the guardrail bolts loosen within a certain range. When loosened, friction still exists between some components of the guardrail plate structure and the guardrail adjustment piece, which also helps to keep the limit slot 1b horizontal. Furthermore, it should be understood that the removal steps for the guardrail adjustment piece are the opposite of the assembly steps, making both disassembly and assembly operations relatively convenient.

[0033] In one embodiment, see Figure 2 The adjustment piece body 1 has a counterweight end 11 and a main body end 12 located at opposite ends. The avoidance groove 1a is formed on the side of the adjustment piece body 1 close to the counterweight end 11. The limiting groove 1b is located on the side of the avoidance groove 1a close to the main body end 12 and is connected to the upper end of the avoidance groove 1a. Its extension direction is consistent with the layout direction of the counterweight end 11 and the main body end 12. The counterweight block 2 is arranged at the counterweight end 11.

[0034] In this embodiment, the avoidance groove 1a is located at the end of the adjustment plate body 1 near the counterweight 2, and the limiting groove 1b is located on the side of the avoidance groove 1a near the main body end 12. This makes the overall structural distribution more reasonable, facilitates the limiting groove 1b to balance to the horizontal direction, and improves the compactness of the guardrail adjustment plate. It should be noted that in one embodiment, the avoidance groove 1a and the limiting groove 1b are connected at a right angle.

[0035] In one embodiment, the counterweight 2 is integrally connected to the adjustment plate body 1 and is located at the counterweight end 11 and extends in a direction away from the body end 12 .

[0036] In this embodiment, the counterweight 2 is integrally connected to the adjustment plate body 1, which facilitates casting and also makes it easier for the operator to hold the counterweight 2 to install the guardrail adjustment plate, thereby improving assembly convenience. It should be noted that in one embodiment, the surface of the counterweight 2 is provided with anti-slip stripes.

[0037] In one embodiment, the guardrail adjustment piece further includes an anti-slip structure 3, which is provided on the adjustment piece body 1 and is used to limit the movement of the adjustment piece body 1 relative to the bolt along the direction from the avoidance groove 1a to the limiting groove 1b.

[0038] In this embodiment, an anti-slip structure 3 is also provided on the adjustment piece body 1 to limit the movement of the adjustment piece body 1 to the position where the guard rail bolt enters the avoidance groove 1a from the limiting groove 1b, further reducing the probability of the guard rail adjustment piece moving upward and improving its installation stability.

[0039] In one embodiment, the anti-slip structure 3 includes an anti-slip spring piece 31 , one end of which is connected to a side wall of the limiting groove 1 b , and the other end of which is spaced apart from the other side wall of the limiting groove 1 b .

[0040] In this embodiment, when the guardrail bolt enters the end of the limiting groove 1b away from the avoidance groove 1a, the operator applies external force to the adjustment plate body 1, causing the guardrail bolt to bend the anti-slip spring plate 31. However, the force exerted by the track during vibration is insufficient to bend the anti-slip spring plate 31, thereby effectively preventing the guardrail bolt from disengaging from the limiting groove 1b, improving installation stability, and preventing the guardrail adjustment plate from moving upward.

[0041] In one embodiment, see Figure 3The side wall of the limiting groove 1b is provided with a mounting groove 1c, one end of the anti-drop spring 31 is connected to the bottom wall of the mounting groove 1c, and is spaced apart from the side wall of the mounting groove 1c, and the other end extends from the mounting groove 1c into the limiting groove 1b.

[0042] In this embodiment, the anti-drop spring piece 31 is placed in the installation groove 1c, so that the size fit between the guard rail bolt and the limiting groove 1b can be tighter, avoiding the guard rail adjustment piece from moving up due to the large size gap between the limiting groove 1b and the guard rail bolt.

[0043] In one embodiment, a rubber sleeve 32 is provided on one end of the anti-slip spring piece 31 extending from the mounting groove 1c into the limiting groove 1b; an arc surface is provided on one end of the anti-slip spring piece 31 extending from the mounting groove 1c into the limiting groove 1b, and the extension direction of the arc surface is consistent with the extension direction of the limiting groove 1b.

[0044] In this embodiment, a rubber sleeve 32 and an arc surface are provided so that the rail guard bolt can enter and exit the limiting groove 1b more smoothly under the driving of external force, thereby improving convenience.

[0045] In one embodiment, there are two groups of mounting grooves 1c, which are located on the two opposite side walls of the limiting groove 1b; there are two groups of anti-slip spring plates 31, which are respectively arranged in the two groups of mounting grooves 1c, and the two groups of anti-slip spring plates 31 are located at one end of the limiting groove 1b and are spaced apart.

[0046] In this embodiment, two groups of anti-slip spring pieces 31 are provided to effectively prevent the rail guard bolts from escaping from the limiting grooves 1 b and improve the anti-slip capability.

[0047] In one embodiment, the anti-slip structure 3 further includes a magnetic sheet 33 . The magnetic sheet 33 is disposed on the adjustment sheet body 1 and is used to be magnetically attracted to the rail support of the guardrail pad structure.

[0048] In this embodiment, a magnetic attraction piece 33 can be provided on the adjusting piece body 1 to magnetically attract the adjusting piece body 1 to the rail support, thereby preventing the adjusting piece body 1 from moving under vibration to a position where the guardrail bolt enters the avoidance groove 1a. It should be noted that in one embodiment, the sidewalls of the avoidance groove 1a are also provided with anti-slip stripes. This increases the friction between the sidewalls of the avoidance groove 1a and the guardrail bolt if the guardrail bolt accidentally enters the avoidance groove 1a, thereby reducing the probability of the guardrail adjusting piece moving upward.

[0049] In addition, the present invention further provides a guardrail pad structure, which includes a guardrail adjustment piece as described in any one of the above items. It should be noted that the detailed structure of the guardrail adjustment piece of the guardrail pad structure can be referred to the embodiments of the guardrail adjustment piece described above, and will not be repeated here. Since the guardrail adjustment piece described above is used in the guardrail pad structure of the present invention, the embodiments of the guardrail pad structure of the present invention include all technical solutions of all embodiments of the guardrail adjustment piece described above, and the technical effects achieved are also identical, and will not be repeated here.

[0050] In order to better understand the present invention, the following Figures 1 to 3 The technical solution of the utility model is described in detail:

[0051] The main body 1 of the adjustment plate, balanced by the counterweight 2, positions the retaining groove 1b horizontally, above the avoidance groove 1a. Consequently, when the guardrail bolt loosens, the retaining groove 1b remains horizontal due to the center of gravity of the guardrail adjustment plate. This prevents the sidewalls of the retaining groove 1b from being stopped by the guardrail bolt during track vibration, effectively preventing the guardrail adjustment plate from moving above the guardrail and eliminating potential driving safety hazards. Furthermore, the anti-drop spring 31 prevents the main body 1 from moving to the point where the guardrail bolt enters the avoidance groove 1a from the retaining groove 1b, further preventing the guardrail adjustment plate from moving upward and ensuring its stable installation.

[0052] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
