Description

Technical Field

[0001] The utility model relates to the field of guard rails, in particular to a novel guard rail. Background Art

[0002] Guardrails refer to the steel rails laid inside or outside the track. Their main function is to assist in guiding the track wheels to prevent them from derailing and other situations that are not conducive to traffic. Due to the complex underground environment, rail trolleys often involve turnouts and slope changes, so guardrails are widely used.

[0003] Guardrails in the prior art are mostly modified from discarded I-rails, but the weight and difficulty of assembling the I-rails result in a cumbersome construction process and high cost. Specifically, during assembly, the I-rails require pressure blocks to be placed on both sides of the rails, and additional spikes are required for their fixation. Under the condition that the guardrails do not bear excessive loads, this construction process places a great burden on the workers. At the same time, due to the heavy weight of the I-rails, the operating pressure of the hanging rail mechanism will be greatly increased during laying and withdrawal, resulting in a slow construction process. There is currently a lack of corresponding solutions to the above problems. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and, in view of the low utilization rate of a large number of discarded channel steels, I-beams or angle irons underground, provide a new type of guardrail with lower cost, more convenient transportation and assembly, and reduce the guardrail layout cost and working hours on the basis of ensuring the normal operation of the guardrail.

[0005] The equipment includes a connecting rib beam, which is the assembly basis of the equipment;

[0006] Guardrails are respectively arranged on both sides of the connecting rib beam;

[0007] An assembly angle plate is integrally connected to the outer side of the guard rail, and an assembly through hole is arranged on the bottom surface of the assembly angle plate. The assembly angle plates are evenly arranged in an array on the outer side of the guard rail.

[0008] The effect achieved in this way is that the through holes on the assembly angle plate are used as the assembly basis, and the guardrail is fixed to the rail sleepers by screws or fixed to the tunnel ground by anchor rods.

[0009] The beneficial effects of the utility model are as follows: the utility model solves the problem of difficulty in assembling and transporting underground guardrails in the prior art, and provides a new guardrail that can be modified using angle irons, channel steels and I-beams, which has a higher utilization rate of waste materials. In particular, the equipment structure is simpler, the assembly is more convenient, and it is easy to disassemble and transport, which has greater safety promotion value.

[0015] The realization, functional features and advantages of the purpose of the present utility model will be further described with reference to the embodiments and the accompanying drawings. Specific embodiments

[0016] Referring to Figure 1 , Figure 2 , a new type of guard rail described in the present utility model includes a connecting rib beam 2, and the connecting rib beam 2 is the assembly basis of this equipment;

[0017] On both sides of the connecting rib beam 2, guard rails 1 are respectively arranged;

[0018] On the outer side of the guard rail 1, an assembly angle plate 3 is integrally connected. The bottom surface of the assembly angle plate 3 is provided with assembly through holes, and the assembly angle plates 3 are uniformly arranged in an array on the outer side edge of the guard rail 1.

[0019] The achieved effect is that with the through holes on the assembly angle plate 3 as the assembly basis, the guard rail 1 is fixed on the track sleeper by a screw rod or fixed on the roadway ground by driving an anchor rod.

[0020] Embodiment 1, referring to the accompanying drawings of the specification Figure 1 , the guard rail 1 is an angle iron, the connecting rib beam 2 is fixed to the inner surface of one side plate of the angle iron, and the guard rails 1 on both sides are arranged symmetrically in a mirror image.

[0021] Embodiment 2, referring to the accompanying drawings of the specification Figure 1 , the guard rail 1 is a channel steel or an I-beam, the connecting rib beam 2 is fixed in the groove body of the channel steel or the I-beam, and the guard rails 1 on both sides are arranged symmetrically in a mirror image.

[0022] The achieved effect is that considering the situation of a large amount of waste channel steel, I-beam or angle iron with low utilization rate in the underground, the top surface and side surface of the above materials are used as the base surface of the guard rail 1. In this case, the utilization rate of the materials can be higher, the layout cost can be lower, the equipment quality can be lighter, and the loading and transportation are more convenient.

[0023] Furthermore, the assembly angle plate 3 is in the form of an angle iron.

[0024] Furthermore, assembly holes are evenly arrayed on the guard rail 1;
