Description

Technical Field

[0001] The utility model belongs to the technical field of railway emergency parking in construction sections, in particular to an abnormal emergency parking system for railways in construction sections. Background Art

[0002] Amidst urbanization and the upgrading of municipal infrastructure, intersections between railways and municipal roads are becoming increasingly frequent. In these projects, particularly those involving open-cut excavation and concrete frame bridge construction beneath or adjacent to existing railways, ensuring that construction activities do not interfere with railway operations and guaranteeing train safety has become a pressing technical challenge.

[0003] Traditional construction monitoring methods rely primarily on manual monitoring of the construction site and feedback to the control room, enabling trains to be stopped in emergencies. However, this manual monitoring approach has significant limitations: First, manual monitoring has a long response time, which cannot meet the rapid response requirements in emergencies. Second, manual monitoring has difficulty effectively detecting even small deformations and displacements, which can lead to delayed identification and response to potential hazards, increasing construction risks and potential safety hazards in train operations.

[0004] To address these issues, this utility model proposes a railway emergency stop system for pit construction sections. This system aims to improve construction safety and train operation safety through automated monitoring and early warning mechanisms. Using intelligent monitoring equipment, the system enables real-time monitoring of the construction area, promptly identifying and responding to potential construction risks, and effectively preventing the adverse impact of construction activities on railway operations. Utility Model Content

[0005] The purpose of this utility model is to solve the above problems and provide a railway emergency stop system in a construction section, comprising:

[0006] The monitoring mechanism further comprises a fixed seat, a fixed plate is fixedly mounted on the top of the fixed seat, a rotating seat is fixedly mounted on the upper surface of the fixed plate, a fully automatic total station is arranged on the upper surface of the rotating seat, and a signal transmitter is fixedly mounted on the lower wall of the fixed plate;

[0007] A knife switch, a speaker is fixedly installed on the upper end of one side of the knife switch, a warning light is fixedly installed on one side of the speaker, the speaker is connected to the signal transmitter, and a track connecting line is fixedly installed on the lower end of the knife switch.

[0008] Through the above technical solution, the track connecting line is connected to the track, and the fully automatic total station is set up in the construction area. The existing track, D-beam and its supporting piles, roadbed slope, contact network pillars and surrounding buildings in the construction area are continuously and fully automatically monitored by the fully automatic total station. When the monitored data exceeds the preset safety range, the system will automatically send an early warning signal to the construction site and the control room. At this time, the speaker on one side of the knife switch will sound an alarm and the warning light will flash. After receiving the early warning, the operator in the control room will quickly confirm the situation on the scene. Once it is confirmed that there is an abnormal situation, or the on-site responsible personnel find that there is a threat to driving safety, before an accident occurs that may collide with the locomotive, people, machines, materials and tools, the operator can close the knife switch in an emergency, thereby achieving an emergency stop of the train to prevent possible safety accidents.

[0009] In a preferred embodiment, the track connecting line is electrically connected to the third rail at a side away from the knife switch.

[0010] In a preferred embodiment, two slide rails are fixedly mounted on one side of the fixed plate, outer walls of the two slide rails are slidably connected to sliders, and one side of the two sliders is fixedly mounted with a protective cover.

[0011] Through the above technical solution, when construction in the construction area stops, the slider drives the protective cover to move downward along the slide rail, thereby covering the outer wall of the fully automatic total station to prevent it from being damaged.

[0012] In a preferred embodiment, the monitoring mechanism is set up in the construction area.

[0013] In a preferred embodiment, the knife switch is arranged in a switch control room.

[0014] In a preferred embodiment, the signal transmitter and the speaker are connected via a GPRS signal.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows: the present invention proposes an abnormal emergency parking system for railways in construction sections.

[0016] 1. Connect the track connecting line to the track, set up the fully automatic total station in the construction area, and use the fully automatic total station to continuously and fully automatically monitor the existing tracks, D-beams and their supporting piles, roadbed slopes, contact network pillars and surrounding buildings in the construction area. When the monitored data exceeds the preset safety range, the system will automatically send an early warning signal to the construction site and the control room. The speaker on one side of the knife switch will sound an alarm and the warning light will flash. After receiving the early warning, the operator in the control room will quickly confirm the on-site situation. Once it is confirmed that there is an abnormal situation, or the on-site responsible personnel find that there is a threat to driving safety, or before an accident occurs that there is a collision between the locomotive, people, machines, and materials, the operator can close the knife switch in an emergency, thereby achieving an emergency stop of the train to prevent possible safety accidents.

The monitoring mechanism 1 is set in the construction area;

[0027] The knife switch 2 has a speaker 21 fixedly mounted on the upper end of one side of the knife switch 2. The signal transmitter 18 and the speaker 21 are connected via a GPRS signal. A warning light 22 is fixedly mounted on one side of the speaker 21. The speaker 21 is connected to the signal transmitter 18 by signal. A track connecting line 23 is fixedly mounted on the lower end of the knife switch 2. The track connecting line 23 is electrically connected to the third rail away from the side of the knife switch 2. The knife switch 2 is set in the switch control room. The track connecting line 23 is connected to the track. The fully automatic total station 14 is set in the construction area. The existing track, D-beam and its supporting piles, and road in the construction area are measured by the fully automatic total station 14. The base slope, contact network pillars and surrounding buildings are continuously and fully automatically monitored. When the monitored data exceeds the preset safety range, the system will automatically send an early warning signal to the construction site and the control room. In this case, the speaker 21 on the side of the knife switch 2 will sound an alarm and the warning light 22 will flash. After receiving the early warning, the operator in the control room will quickly confirm the on-site situation. Once an abnormal situation is confirmed, or the on-site responsible personnel find that there is a threat to driving safety or an accident with locomotives, people, machines, and materials occurs, the operator can close the knife switch 2 in an emergency, thereby achieving an emergency stop of the train and preventing possible safety accidents.

[0028] Two slide rails 15 are fixedly installed on one side of the fixed plate 12, and the outer walls of the two slide rails 15 are slidably connected with sliders 16. A protective cover 17 is fixedly installed on one side of the two sliders 16. When construction in the construction area is stopped, the sliders 16 drive the protective cover 17 to move downward along the slide rails 15, thereby covering the outer wall of the fully automatic total station 14 to prevent it from being damaged.

[0029] Working principle:

[0030] The track connecting line 23 is connected to the track, and the fully automatic total station 14 is set in the construction area. The existing track, D-beam and its supporting piles, roadbed slope, contact network pillars and surrounding buildings in the construction area are continuously and fully automatically monitored by the fully automatic total station 14. When the monitored data exceeds the preset safety range, the system will automatically send an early warning signal to the construction site and the control room. At this time, the speaker 21 on one side of the knife switch 2 will sound an alarm and the warning light 22 will flash. After receiving the early warning, the operator in the control room will quickly confirm the situation on the scene. Once it is confirmed that there is an abnormal situation, or the on-site responsible personnel find that there is a threat to driving safety, before an accident occurs that the locomotive, people, machines, and materials collide, the operator can close the knife switch 2 in an emergency, thereby achieving an emergency stop of the train to prevent possible safety accidents.
