Description
Technical Field
The invention relates to the technical field of rail transit safety protection devices, in particular to a use method of a hydraulic electric car arrester for rail transit.
Background
Rail traffic refers to a type of vehicle or transportation system in which an operating vehicle needs to travel on a particular track. The most typical rail traffic is a railway system consisting of conventional trains and standard railroads. With the diversification development of train and railway technologies, rail traffic is of more and more types, and is widely applied to urban public transportation in medium and short distances as well as land transportation in long distances. Common rail transit is a conventional railway (national railway, inter-urban railway and urban railway), a subway, a light rail and a tramcar, and novel rail transit is a magnetic levitation track system, a monorail system (straddle-type track system and suspension-type track system), a passenger automatic shortcut system and the like. In national standard "common term of urban public transportation", urban rail transit is defined as a general term of rapid mass public transportation which usually uses electric energy as power and adopts wheel-rail operation mode. "track traffic is generally classified into three major categories of national railway system, inter-urban track traffic and urban track traffic according to service range differences. Rail transit generally has advantages of large traffic volume, fast speed, dense shifts, safety and comfort, high standard point rate, all weather, low freight cost, energy conservation, environmental protection and the like, but is accompanied by higher early investment, technical requirements and maintenance cost, and occupied space is often larger. Rail transit in a broad sense refers to various road traffic vehicles consisting of trains, railways, stations and dispatch systems (including dispatch equipment and dispatch personnel) together, including all conventional railway systems and new track systems. The main body of the generalized rail traffic is the traditional railway, including the high-speed railway. Rail transit in the narrow sense generally refers to urban rail, namely two major types of inter-urban rail transit and urban rail transit, such as bead triangle inter-urban rapid rail transit, dongguan rail transit and the like. In general, rail transit is used more often to call various medium and short distance passenger railway systems newly built in economically developed areas. In the early days, some local governments or mass media do not know that many intercity rail transit is built by adopting a national iron system, namely intercity railways and urban irons for short, so that many actual intercity railways are commonly called intercity rails and urban rails for short, such as Guangzhu urban rails, guangxi Hui Cheng rails and the like. In fact, they belong to the category of inter-urban railways in inter-urban rail transit, being part of the branch road network in national railways. In the early days, some local governments or mass media do not know that many intercity rail transit is built by adopting a national iron system, namely intercity railways and urban irons for short, so that many actual intercity railways are commonly called intercity rails and urban rails for short, such as Guangzhu urban rails, guangxi Hui Cheng rails and the like. In fact, they belong to the category of inter-urban railways in inter-urban rail transit, being part of the branch road network in national railways. The subway system is the most widely used railway system type in urban rail transit, and rail transit bodies in most cities are also subway systems. Therefore, the rail transit of a part of cities is outlined as a 'subway', and certain city subway companies, such as Guangzhou subway, are established. However, the "subway" herein is not limited to the subway system, but includes other types of rail traffic in the city, such as "Guangzhou subway" including an automatic passenger shortcut system (APM) different from the subway system. The rail traffic is a complex system integrating multiple professions and multiple species, and is generally composed of a rail route, a station, a vehicle, a maintenance and overhaul base, power supply and transformation, communication signals, a command control center and the like. The transportation organization, function realization and safety guarantee of urban rail transit all follow the objective rule of rail transit. Centralized dispatching, unified command and running organization according to running diagrams are carried out on the transportation organization. In terms of function realization, various related professions such as lines, stations, tunnels, vehicles, power supply, communication, signals, electromechanical equipment and fire protection systems are guaranteed to be in good states and run normally. In the aspect of safety assurance, the necessary driving interval and correct driving line are ensured mainly by the normal operation of driving organizations and equipment. Urban rail transit is a public transportation facility provided with a fixed line, a fixed track, a transportation vehicle, a service facility, and the like. "urban rail transit" is a concept that includes a wide range and is internationally not uniformly defined. In general, urban rail transit in a broad sense is characterized by a rail transit system, which is a rail transit system (different from road traffic) with medium or higher traffic in urban public passenger transit systems, mainly serves public passenger traffic in cities (different from inter-urban railways, but covering suburban areas and urban areas), and is a modernized three-dimensional transit system playing a role in urban public passenger transit.
The rail transportation is a guide body which uses a rail as a bearing, a vehicle is used as a transportation container, in order to improve the working efficiency of workers in mines and reduce the fatigue of the workers, a mine car is usually used for conveying bulk materials such as coal, ore, waste rocks and the like on narrow gauge railways, the car stopper is an indispensable limiting protection device in mine rail transportation, the car stopper can stop a mine car moving in a mine transportation field at a certain fixed place, the running vehicle can be conveniently and rapidly stopped slowly, the car stopper is a wheel of the mine car, the running of the mine car can be effectively prevented, the mine car stays at the position where the mine car needs to stay, the working amount of the workers is reduced, the working efficiency is greatly improved, the safety accident caused by sliding is avoided, the safety of mine operation is improved, the car stopper in the prior art generally realizes the braking of the mine car by means of hydraulic pressure, but in actual use, due to a certain damping process, the hydraulic braking system is used, the car stopper can not stop the mine car rapidly by means of the hydraulic pressure mode easily when the overload is caused, and further accidents can be caused.
Meanwhile, in the braking process of the mine car, when the mine car is in a completely stopped state, the mine car is braked by the aid of the hydraulic system, if the mine car is braked by the hydraulic system for a long time, overload of the hydraulic system can be caused, the service life of the hydraulic system can be reduced after the hydraulic system is used for a long time, and the service life of the hydraulic system is reduced easily due to the fact that an auxiliary braking device after braking is lacked in the prior art.
Meanwhile, because the weight of the mine car is generally heavier, when the mine car contacts with the hydraulic system, the mine car can be slowly stopped by the reverse acting force provided by the hydraulic system, but because the load of the hydraulic system is limited, when the mine car is overloaded, the pressure acting on the hydraulic system is obviously increased, and the hydraulic system is lack of a buffer device and is easy to damage the hydraulic braking system, the wheels have larger kinetic energy due to the influence of the mine car in the actual braking process, the collision phenomenon can occur between the wheels and the stop block, vibration generated by the collision is likely to be conducted to the hydraulic system, the parts inside the hydraulic system can be greatly influenced, the service life of the parts inside the hydraulic system is reduced, and the actual use is influenced.
