Description
Technical field
The utility model belongs to subway technical field, is specifically related to a kind of device preventing underground automobile door from being extruded by passenger.
Background technology
Along with the develop rapidly of Construction of Urban Rail Traffic, the transportation mode of track traffic is more and more applied.And track traffic has that freight volume is large, speed fast, safety, on schedule, take the features such as amenity, economize energy, pollution be little like by numerous citizen, be trip best preferred manner.
Along with increasing of passenger, in addition limited seat, causes most of passenger to take advantage of at station, however have quite a few passenger be accustomed to lean on inner side car door (right side of travel direction) stand.When train operation, because passenger rests on car door, it is larger that train shakes in the process of moving, rock etc. makes passenger be squeezed in car door upward pressure, and this force value is much larger than the operating pressure considered during research of door design, this just causes the contact car door bottom slide block in Train door system and outer threshold being installed friction lining to increase, wearing and tearing aggravation, substantially reduces its service life, adds its operation cost.Meanwhile, car door is therefore aggravation distortion also, even exceeds the deflection that it allows, and produces permanent deformation, causes car door when opening and train side sheet or inner side trim board rub, even stuck, normally can not open car door.Reliability reduces, and safety declines, and causes potential potential safety hazard.
Summary of the invention
For overcoming above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of device preventing underground automobile door from being extruded by passenger, biparting sliding door locks can be realized automatically lock, unlock and the function of manual unlocking, make that door lock assembly is compacter, simple, reliability is higher, reduce slip every body weight, have lighter, steerability is higher, the feature that fault rate is lower and maintenance is easier.
For achieving the above object, the technical solution adopted in the utility model is: a kind of device preventing underground automobile door from being extruded by passenger, includes the outer threshold be located between vehicle outside wallboard and car door, each outer threshold is provided with a friction lining; Friction lining is provided with pressure sensor; Pressure sensor is connected with microprocessor; Microprocessor is connected with alarm speaker and display alarm device.
Described pressure sensor is located at door outside.
Described pressure sensor is located at car door lower end when two winnowing machine doors are in buttoned-up status and the position contacted with friction lining.
Described pressure sensor is corresponding with detected car door to be arranged, and each pressure-detecting device is separate, does not interfere with each other, and does not affect train and normally travels.
The beneficial effects of the utility model are:
The utility model adds the automatic checkout equipment leaning on car door with or without passenger on existing Train door, ensure that and prevent from making car door et out of order because passenger leans on Train door, contribute to the wearing and tearing alleviating car door bottom slide block and friction lining, it also avoid simultaneously and cause car door to deform because passenger leans on car door, cause car door when opening and train side sheet or inner side trim board rub, even stuck, the situation normally can not opening car door occurs.Reduce the fault rate of car door, improve reliability and the safety of car door, decrease the impact that human element causes, improve operation work efficiency.

In figure: 1, pressure sensor; 2, friction lining; 3, outer threshold; 4, flathead screw; 5, inner door sill; 6, car body; 7, floor cloth; 8, inner door sill pressing plate; 9, car door; 10, vehicle outside wallboard; 11, finger shield adhesive tape.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See Fig. 1,2,3, a kind of device preventing underground automobile door from being extruded by passenger, includes the outer threshold 3 be located between vehicle outside wallboard 10 and car door 9, and each outer threshold 3 is provided with a friction lining 2; Friction lining 2 is provided with pressure sensor 1; Pressure sensor 1 is connected with microprocessor; Microprocessor is connected with alarm speaker and display alarm device.
Described pressure sensor 1 is located at outside car door 9.
Described pressure sensor 1 is located at car door lower end when two winnowing machine doors 9 are in buttoned-up status and the position contacted with friction lining.Described friction lining 2 is fixed on outer threshold 3 by flathead screw 4.
Be movably connected with inner door sill 5 inside car door 9; Inner door sill 5 top is provided with inner door sill pressing plate 8, and one end of inner door sill pressing plate 8 is pressed on floor cloth 7.
Finger shield adhesive tape 11 is provided with between two adjacent pressure sensors 1.
Above-mentioned parts are located on car body 6.
Described operating pressure refers at train under normal operating conditions, and Train door is closed, and when leaning on car door without passenger, train can shake in the process of moving, wave etc. and the pressure of generation.When the force value that pressure sensor detects is less than or equal to setup pressure value (according to train driving condition adjustable), illustrates that car door is in normal condition, lean on this car door without passenger, warning device does not just send the output signal of " please don't lean on car door ".
Described setup pressure value refers at train under normal operating conditions, on the basis of the pressure produced because shaking, waving etc. in installation pretightening force, the normal driving process of train, more reserved certain safe pressure (preventing warning device from reporting by mistake).
Principle of work of the present utility model is:
When two winnowing machine doors are in buttoned-up status, in the position that car door lower end contacts with friction lining, two pressure sensors detecting car door and whether have passenger to rely on are set respectively; Two pressure sensors are connected with microprocessor; Microprocessor is connected with alarm speaker and display alarm device respectively;
Set the force value of car door in the microprocessor;
During train operation, pressure sensor detects the pressure on car door, if when the force value detected is greater than setting value, illustrated that passenger leans on this car door, microprocessor sends alerting signal to alarm speaker, exports the voice message that please don't lean on car door;
If when the force value that pressure sensor detects is less than or equal to setting value, illustrate and lean on this car door without passenger, microprocessor does not send alerting signal to alarm speaker, does not export the voice message that please don't lean on car door.
Described force value can adjust according to train driving condition.
