Description

Technical Field

[0001] The present invention relates to the technical field of transportation, and more particularly to an anti-overturning guardrail pad. Background Art

[0002] In the prior art, guard rail 08 refers to a steel rail that is added inside the base rail 07 of the track and does not bear the vertical load of the wheels. The gap between guard rail 08 and base rail 07 is for the wheels to pass through. Common guard rail pad structures are as follows: Figure 1 As shown, it includes a base plate 01, an iron seat 02, a fastener 03, a rail clip plate 04, a fixed platform plate 05 and a fixed support plate 06, wherein the base plate 01 is used to carry the basic rail 07, the iron seat 02 and the fastener 03 are used to fix one side of the basic rail 07, and the other side of the basic rail 07 is fixed by the buckling groove of the rail clip plate 04, the fixed platform plate 05 is used to vertically carry the guard rail 08, the fixed support plate 06 is used to horizontally fix the guard rail 08, the fixed support plate 06 and one side of the fixed platform plate 05 are welded together and are all welded to the rail clip plate 04, the rail clip plate 04, the iron seat 02 and the fastener 03 are all welded to the base plate 01, the waist of the guard rail 08 is fastened to the fixed support plate 06 by bolts 010, and an adjustment piece 09 is provided between the guard rail 08 and the fixed support plate 06 to facilitate spacing adjustment.

[0003] The structure of the guardrail pad is simple, but it has the following defects in long-term application:

DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] The core of the present invention is to provide an anti-overturning guardrail pad, which can solve the problem of guardrail overturning caused by easy failure of bolts and reduce the probability of train derailment accidents.

[0036] Please refer to Figures 2 to 9 .

[0037] This specific embodiment provides an anti-overturning guardrail pad, including: a base plate 1 for carrying a basic rail 7, an iron seat 2, a fastener 3, a rail clip 4, a fixed platform 5 for vertically carrying a guardrail 8, and a fixed support plate 6 for horizontally fixing the guardrail 8. The iron seat 2 and the fastener 3 are used in conjunction with each other to fix the rail limb on one side of the basic rail 7, and the rail clip 4 is used to fix the rail limb on the other side of the basic rail 7. The fixed support plate 6 and one side of the fixed platform 5 are in contact with each other and are both arranged on the rail clip 4. The rail clip 4, the iron seat 2 and the fastener 3 are all arranged on the base plate 1. The waist 13 of the guardrail 8 is connected to the fixed support plate 6. It also includes a clamp-shaped stopper 10, the upper part of the clamp-shaped stopper 10 is a clamp-shaped bayonet structure 11, and the lower part of the clamp-shaped stopper 10 is a U-shaped double-rib structure 12. The two ends of the fixed platform 5 are respectively connected to the U-shaped double-rib structure 12, and the clamp-shaped bayonet structure 11 is gap-fitted with the rail waist 13.

[0038] It should be noted that a pressing groove can be provided at the bottom of the rail clip 4 to effectively fix the rail limb on the other side of the basic rail 7 through the pressing groove. Bolts can be provided on the base plate 1 to ensure that the base plate 1 is stably fixed on the ground. Moreover, an adjustment plate 9 can be provided between the guard rail 8 and the fixed support plate 6 to facilitate adjustment of the spacing between the basic rail 7 and the guard rail 8. The above-mentioned clamp-shaped bayonet structure 11 is clearance-matched with the rail waist 13, which means that the shape and size of the upper part of the clamp-shaped stopper 10 are matched with the shape and size of the rail waist 13, so that the clamp-shaped bayonet structure 11 and the rail waist 13 are clamped and fixed, and a gap is left at the clamping point.

[0039] During actual use, the shape, structure, size, material, position, etc. of the base plate 1, iron base 2, fastener 3, rail clip plate 4, fixed platform 5, fixed support plate 6 and clamp-shaped block 10 can be determined according to actual conditions and actual needs.

[0040] When using the anti-overturning guardrail pad provided by the present invention, the clamp-shaped bayonet structure 11 on the upper part of the clamp-shaped stopper 10 is gap-fitted and clamped with the middle part of the waist 13 of the guardrail 8, the lower part of the clamp-shaped stopper 10 is connected to the fixed plate 5, the fixed support plate 6 and the fixed plate 5 are both arranged on the rail clip 4, the rail clip 4, the iron seat 2 and the fastener 3 are all arranged on the bottom plate 1, and the waist 13 of the guardrail 8 and the fixed support plate 6 can be connected by bolts. When the bolts fail during use and cause the guardrail 8 to overturn due to gravity, the top of the clamp head of the clamp-shaped stopper 10, the upper jaw of the jaw and the upper surface of the fixed plate 5 can respectively contact the inner surface of the long rail limb 22 of the guardrail 8, the inner surface of the short rail limb 21 of the guardrail 8 and the outer surface of the short rail limb 21. Under the interaction of the three contact surfaces, the correct shape and position of the guardrail 8 can be ensured, preventing the guardrail 8 from overturning and causing a train derailment accident.

[0041] In summary, the anti-overturning guardrail pad provided by the present invention can solve the problem that the guardrail 8 is easily overturned due to the failure of bolts, and can reduce the probability of train derailment accidents.

[0042] Based on the above embodiment, preferably, the U-shaped double rib structure 12 includes two ribs arranged opposite to each other, the ribs are provided with a first mounting hole 14, the fixed plate 5 is provided with a second mounting hole 15 aligned with the first mounting hole 14, and the locking member 16 can pass through the first mounting hole 14 and the second mounting hole 15 for fastening operation. Figure 7 As shown, the structure of the fixed platen 5 is as follows Figure 9 shown.

[0043] It should be noted that when installing the lower portion of the clamp block 10, the locking member 16 can be sequentially passed through the first mounting hole 14 and the second mounting hole 15 for tightening, so that the clamp block 10 is fixedly connected to the fixed platen 5, and the upper portion of the clamp block 10 can be clamped to the waist 13 of the straightening guardrail 8 to prevent the guardrail 8 from overturning. The use of the locking member 16 for installation provides space for installation and removal of the clamp block 10, that is, the clamp block 10 can be independently removed or installed without removing the guardrail 8, greatly facilitating subsequent maintenance and replacement operations of the device.

[0044] Preferably, the fixed support plate 6 is provided with two third mounting holes 17, and the rail web 13 is provided with a fourth mounting hole 18 that cooperates with the third mounting holes 17. The locking member 16 can be passed through the third and fourth mounting holes 17, 18 for tightening. The locking member 16 herein has the same structure as the bolt member described above. Since the fixed support plate 6 and the guardrail 8 are fixedly connected via the two locking members 16, the probability of the guardrail 8 tipping over due to failure of the locking member 16 is greatly reduced.

[0045] Preferably, locking member 16 comprises a fastening bolt, a nut, a flat washer, a spring washer, and a cotter pin. The end of the fastening bolt is provided with a through-hole for receiving the cotter pin. When fastening member 16 is required, the fastening bolt can be inserted into the component to be connected. The nut, flat washer, and spring washer are then sequentially fitted around the outer periphery of the fastening bolt. Finally, the cotter pin is inserted into the through-hole at the end of the fastening bolt. This prevents the nut from loosening or vibrating off during use, thereby improving the fastening effect of locking member 16. For example, a through-hole with a diameter of 5 mm can be provided 5 mm to 10 mm from the end of the fastening bolt.

[0046] Based on the above embodiment, preferably, a main reinforcing rib 19 and two secondary reinforcing ribs 20 are provided on the side of the fixed support plate 6 away from the fixed platform 5. The main reinforcing rib 19 is arranged relative to the central axis of the fixed support plate 6, and the secondary reinforcing ribs 20 are symmetrically arranged on both sides of the main reinforcing rib 19. The fixed support plate 6 can be configured as a rectangular plate structure with a certain thickness, and multiple reinforcing ribs can be provided on one side of the rectangular plate structure to effectively improve the supporting strength of the fixed support plate 6 and prevent the fixed support plate 6 from deforming and overturning.

[0047] Preferably, the main reinforcing ribs 19 and the secondary reinforcing ribs 20 are welded and fixed to the fixed support plate 6, so that the main reinforcing ribs 19, the secondary reinforcing ribs 20 and the fixed support plate 6 are an integrated structure, which together constitute a support plate frame structure with a supporting function and can simplify the assembly process of the device.

[0048] During actual use, the shape, structure, size, material, position, etc. of the main reinforcing ribs 19 and the secondary reinforcing ribs 20 can be determined according to actual conditions and actual needs.

[0049] Preferably, the fixed table plate 5 and the fixed support plate 6 are both welded to the rail clip plate 4, the rail clip plate 4 is welded to the base plate 1, and the fixed table plate 5 and the fixed support plate 6 are welded and fixed to improve the overall structural strength of the device and simplify the assembly process of the device.

[0050] Preferably, a first gap P1 is provided between the clamp block 10 and the short rail leg 21 of the guard rail 8, a second gap P2 is provided between the clamp block 10 and the rail waist 13, and the first gap P1 and the second gap P2 are both 6mm to 12mm; a third gap P3 is provided between the clamp block 10 and the inner vertical surface of the long rail leg 22 of the guard rail 8, and a fourth gap P4 is provided between the clamp block 10 and the inner vertical surface of the short rail leg 21, and the third gap P3 and the fourth gap P4 are both 1mm to 3mm. The structure is as follows Figure 5 shown.

[0051] It should be noted that after the clamp block 10 is installed in place, a first gap P1 is reserved between the clamp block 10 and the short rail limb 21 of the guard rail 8, and a second gap P2 is reserved between the clamp block 10 and the rail waist 13, so as to reserve adjustment space for subsequent wear and consumption of the guard rail 8, and also provide space for fine-tuning the lateral position of the guard rail 8 to ensure that the spacing L between the base rail 7 and the guard rail 8 remains within the preset range.

[0052] It should also be noted that the inner surface of the long rail limb 22 and the inner surface of the short rail limb 21 refer to the opposite side of the long rail limb 22 and the short rail limb 21, and the outer surface of the long rail limb 22 and the outer surface of the short rail limb 21 refer to the opposite side of the long rail limb 22 and the short rail limb 21. A third gap P3 is reserved between the clamp block 10 and the inner surface of the long rail limb 22, and a fourth gap P4 is reserved between the clamp block 10 and the inner surface of the short rail limb 21. Both the third gap P3 and the fourth gap P4 should not be too large to ensure that the clamp block 10 can effectively prevent the guardrail 8 from overturning if the bolts of the guardrail 8 fail.

[0053] It should be noted that the first gap P1, the second gap P2, the third gap P3, the fourth gap P4, the first mounting hole 14, the second mounting hole 15, the third mounting hole 17, and the fourth mounting hole 18 mentioned in this application document, where the first and second and the third and the fourth are only to distinguish the different positions, and there is no order of precedence.

[0054] In addition, it should be noted that the orientations or positional relationships indicated by "up and down", "inside and outside", etc. in this application are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the purpose of simplifying the description and facilitating understanding, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
