Description

Technical Field

[0001] The utility model relates to the technical field of bridge guardrails, in particular to an integral guardrail pad. Background Art

[0002] Guardrails are rails that are laid on the inside of the rails on the track and do not bear the vertical load of the wheels. They have different functions depending on the location where they are laid. Guardrails at the turnout frog are laid on the inside of the rails opposite to the harmful space of the frog to guide the wheels through the harmful space to avoid hitting the tip of the fork. Two guardrails on the bridge can prevent derailed vehicles from hitting the bridge or falling under the bridge.

[0003] Existing guardrail pads are usually of simple structure, with a single bolt fixed fastener that is easy to install, but they often have insufficient fastening pressure and poor stability. Since strong vibrations are generated when trains pass during use, the pad structure is not vibration-resistant and displacement-resistant, which causes the fasteners to easily fall off, causing safety hazards.

[0024] The present invention is further described in detail below in conjunction with the embodiments.

[0025] The specific embodiment of the integral guardrail pad provided by the utility model is as follows:

[0026] See also Figure 1-3 The integral guardrail pad comprises a plate body 1; in the present embodiment, two plate bodies 1 are symmetrically provided, and the two plate bodies 1 respectively correspond to the two guardrails 16; the two plate bodies 1 are both arranged on the upper side of the same sleeper, and there is a gap between the two plate bodies 1.

[0027] The plate body 1 is connected to the upper side of the sleeper by bolts. Specifically, the plate body 1 is connected to the sleeper by a first bolt 5. The end of each plate body 1 away from the other plate body 1 is provided with a mounting hole 4 that cooperates with the first bolt 5. In this embodiment, one side of the mounting hole 4 extends to the edge of the plate body 1 and forms an opening that communicates with the inner end of the mounting hole 4, and the mounting hole 4 is L-shaped when viewed from above.

[0028] A serrated area 6 is provided on the upper side of the plate body 1. The serrated area 6 is a part of the upper side of the plate body 1 and is a serrated surface. The serrated area 6 surrounds the inner end of the mounting hole 4. An annular serrated plate 7 is provided on the upper side of the serrated area 6. The first bolt 5 passes through the serrated plate 7. The lower side of the serrated plate 7 is provided with serrations that match the serrated surface of the serrated area 6. The first bolt 5 is an expansion bolt, the lower end of which is connected to the sleeper, and the outer side of the upper end is connected to a nut and an elastic washer. The nut can press the serrated plate 7 against the upper side of the serrated area 6, exert a large downward force on the plate body 1, stabilize the plate body 1 on the upper side of the sleeper, and has a good anti-loosening effect.

[0029] Wings 2 are provided on the lower sides of the two edges of the plate body 1 to fit on the sides of the sleeper. The wing parts 2 on both sides of the plate body 1 form two wings of the plate body 1. The wing parts 2 can limit the horizontal deviation of the plate body 1, ensure that the position of the plate body 1 and the sleeper remains stable, and avoid deflection of the plate body 1 due to vibration.

[0030] A missing section 8 is provided in the middle of the plate body 1, and the missing section 8 divides the plate body 1 into two independent parts, and the two parts of the plate body 1 are connected by the wing part 2, and the wing part 2 connects the two independent parts of the plate body 1 so that the two parts of the plate body 1 and the wing part 2 are connected. The guard rail 16 is placed on the upper side of the sleeper corresponding to the missing section 8, and the direction of the guard rail 16 is perpendicular to the direction of the sleeper, so that the lower side support of the guard rail 16 is still provided by the sleeper.

[0031] The plate body 1 is provided with a clamping structure for clamping the bottom of the guardrail 16; specifically, the clamping structure includes a bending portion 9, a second bolt 11, a buckle plate 12 and a gauge block 13; the bending portion 9 is formed by bending the plate body 1 on one side of the missing section 8 upward and fits on the upper side of the bottom edge of the guardrail 16; the second bolt 11 is passed through the plate body 1 on the other side of the missing section 8, the buckle plate 12 is sleeved on the outside of the second bolt 11, and the gauge block 13 is in contact between the buckle plate 12 and the bottom of the guardrail 16.

[0032] The bending portion 9 and the gauge block 13 press the guardrail 16 tightly against the upper side of the sleeper from both edges of the bottom of the guardrail 16 , i.e., clamp the bottom of the guardrail 16 against the upper side of the sleeper, exerting a large buckling pressure on the guardrail 16 to stabilize the guardrail 16 .

[0033] The plate body 1 is provided with a T-shaped hole 10 for the second bolt 11 to pass through, and the lower side of the plate body 1 is provided with a countersunk hole corresponding to the T-shaped hole 10, and the lower end of the T-shaped hole 10 is located in the countersunk hole, and the second bolt 11 is a T-shaped bolt. During installation, one side of the bottom of the guardrail 16 extends into the lower side of the bent portion 9, and then the head of the second bolt 11 is extended into the T-shaped hole 10, and the second bolt 11 is rotated so that the T-shaped hole 10 clamps the head of the second bolt 11, and the countersunk hole accommodates the head of the second bolt 11; the gauge block 13 is placed, and then the buckle plate 12 is installed, and the elastic washer and nut are used to cooperate with the second bolt 11, so that the gauge block 13 presses the guardrail 16.

[0034] A pressing piece 3 is arranged between the two plate bodies 1 . The pressing piece 3 is connected to the sleeper by bolts and is pressed on the upper sides of the two plate bodies 1 near the ends.

[0035] In this embodiment, the pressing piece 3 is a cylindrical structure with a T-shaped vertical cross-section and is connected to the sleeper through a third bolt 14. The outer diameter of the pressing piece 3 is greater than twice the width of the gap between the two plates 1. The edges of the ends of the plates 1 are provided with lateral grooves 15, and the side surfaces of the pressing piece 3 fit the groove surfaces of the grooves 15. In some embodiments, the pressing piece 3 is an eccentric cylinder.

[0036] The third bolt 14 is an expansion bolt, the lower part of which is connected to the sleeper and passes through the pressing piece 3 upwards. The nut and elastic washer cooperate with the third bolt 14 to press the pressing piece 3. The T-shaped upper end of the pressing piece 3 presses the inner ends of the two plates 1 to achieve vertical limit on the inner ends of the plates 1, forming a stable buckling pressure and having a good anti-loosening effect. The groove 15 at the end of the plate 1 fits with the side of the pressing piece 3, and at the same time forms a horizontal limit, further preventing the horizontal deflection of the plate 1.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments without creative work, or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
