Description

Technical Field

[0001] This utility model relates to the field of guardrail interlocking technology, specifically to a railway crossing guardrail interlocking signal light. Background Technology

[0002] The railway crossing is an important railway-highway level crossing for a port company. It is a vital passageway for the port's railway, with both upstream and downstream lines passing through it. Train traffic is very heavy, and the volume of car traffic is also very large.

[0003] With the increasing number of railway and highway transport vehicles at a certain port, the number of level crossing operations is becoming increasingly busy, averaging more than 100 times a day and night. The safety pressure is increasing, and the level crossing is located on a curve, so locomotive drivers cannot observe the closing status of the level crossing guardrail in time. If the level crossing personnel do not close the guardrail in time, serious traffic accidents such as car-train collisions may occur.

[0004] In view of the safety hazards that exist in the use of railway crossing guardrails, a railway crossing guardrail interlocking signal light is needed to solve the above problems. Summary of the Invention

[0005] This utility model addresses the safety hazards existing in the current use of railway crossing guardrails by proposing an interlocking signal light for railway crossing guardrails to solve the aforementioned problems.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is a railway crossing guardrail interlocking signal light, including a guardrail driver, a guardrail rotatably connected to the guardrail driver, and a limit switch installed on the guardrail driver. The trigger point of the limit switch abuts against the tail end of the guardrail. The limit switch is electrically connected to the crossing signal light. In use, the limit switch is activated by opening and closing the guardrail, and the limit switch controls the signal light to display the signal. This avoids the problem of the signal light indicating passage when the guardrail is not closed, greatly reducing the safety hazards of the crossing guardrail in use. The overall practical effect is good and it is suitable for the renovation of existing crossings.

[0007] Furthermore, the traffic light is connected in series with at least one limit switch. By connecting the traffic light in series with a limit switch, it is possible to prevent the traffic light from displaying incorrectly due to a guardrail not being closed.

[0008] Furthermore, the signal lights use LED light sources.

[0009] Furthermore, the signal lights and limit switches are controlled by an AC contactor.

[0010] Furthermore, the signal lights and limit switches are electrically connected using a four-core cable.

[0011] Furthermore, the traffic lights use both red and green colors.

[0012] The beneficial effects of this utility model are:

[0013] The device operates by opening and closing the guardrail, which in turn drives a limit switch to control the signal lights. This avoids the problem of the signal lights indicating passage when the guardrail is not closed, greatly reducing the safety hazards of the level crossing guardrail. It has good overall practical effect and is suitable for the renovation of existing level crossings. Attached Figure Description

[0017] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0018] like Figure 1As shown in this embodiment, the railway crossing guardrail interlocking signal light proposed by this utility model includes a guardrail driver 1, a guardrail 3 rotatably connected to the guardrail driver 1, and a limit switch 2 installed on the guardrail driver 1. The trigger point of the limit switch 2 abuts against the tail end of the guardrail 3. The limit switch 2 is electrically connected to the crossing signal light. The signal light is connected in series with at least eight limit switches 2. The signal light connected in series with eight limit switches 2 can avoid the situation where the signal light display is incorrect due to a guardrail not being closed. The signal light uses an LED light source. The signal light and the limit switch 2 are controlled by an AC contactor. The signal light and the limit switch 2 are electrically connected by a four-core cable. The signal light uses red and green colors. In use, the limit switch 2 is activated by opening and closing the guardrail 3. The limit switch 2 controls the signal light to display the signal, avoiding the problem of the signal light displaying "passing" when the guardrail 3 is not closed. This greatly reduces the safety hazards of the crossing guardrail during use. The overall practical effect is good and it is suitable for the renovation of existing crossings.
