Description

Technical Field

[0001] The utility model relates to the technical field of rail transit engineering vehicles, in particular to an iron shoe state detection and protection module suitable for an urban rail transit engineering vehicle operation protection system. Background Art

[0002] Urban rail transit engineering vehicle operation protection system: It is a non-communication-based train automatic control auxiliary system that realizes the operation safety protection of engineering vehicles in the vehicle depot / parking lot or mainline operation process and ensures the safe operation of engineering vehicles. The system is mainly composed of a cabinet, an operation protection host, a human-computer interaction unit (also known as a screen display), a switch, an on-board reader, an on-board antenna, a radio antenna (optional), a 4G antenna (optional), an on-board AP host and AP antenna (optional when using WLAN), a video system, a speed sensor and accessories, a pressure sensor, and special cables.

[0003] Iron shoe: a railway device used to brake a moving vehicle or prevent a parked vehicle from slipping away.

[0004] The existing urban rail transit engineering vehicle operation protection system has the following disadvantages:

[0005] 1. The existing urban rail transit engineering vehicle operation protection system does not determine whether the iron shoe has been removed from under the wheel and prevent it from being fixed in the driver's cab when controlling the operation of the engineering vehicle, which poses certain risks;

[0006] 2. There is no iron shoe placement status detection module;

[0007] 3. There is no fixed position for the iron shoe. During the operation of the engineering vehicle, the iron shoe will be vibrated to a moving position, and in extreme cases, it will injure the accompanying driver and passengers. Utility Model Content

[0008] In view of the shortcomings of the prior art, the purpose of the utility model is to provide an iron shoe state detection and protection module suitable for the urban rail transit engineering vehicle operation protection system. On the basis of the urban rail transit engineering vehicle operation protection, an iron shoe state detection and functional protection module is added, and a storage box is provided with a fixed iron shoe placement position, which can solve the problems existing in the prior art.

[0009] The technical solution is to include: an iron shoe storage box, an iron shoe status detection module, and a functional protection module. The feature is that the iron shoe storage box is provided with a fixed iron shoe placement position, and an iron shoe status detection module is provided at the iron shoe placement position, which can detect in real time whether the iron shoe has been placed properly, and send the iron shoe status detection result to the urban rail transit engineering vehicle operation protection system. The urban rail transit engineering vehicle operation protection system will output a control signal to the functional protection module according to whether the iron shoe is correctly placed. The functional protection module controls the engineering vehicle through the brake to allow the motor vehicle to operate.

[0010] Preferably, the iron shoe state detection module uses two proximity switches, and the proximity switches use the IUSSeries intelligent ultra-small cylindrical proximity switches of Mibo Company.

[0011] The beneficial effects of the utility model are as follows: on the basis of the urban rail transit engineering vehicle operation protection system, an iron shoe state detection module and a functional protection module are added. After the urban rail transit engineering vehicle operation protection system is powered on, it is controlled by default as if the iron shoe is not placed, and the vehicle is not allowed to move. At the same time, the iron shoe state is detected in real time. When the driver performs the iron shoe confirmation operation and the urban rail transit engineering vehicle operation protection system detects that both iron shoes are correctly placed, the vehicle is allowed to move, thereby improving the safety and availability of the urban rail transit engineering vehicle operation protection system.
