Description

Go up footboard automatic timing alarm device

Technical Field

The utility model relates to an instrument and meter technical field specifically is an go up footboard automatic timing alarm device.

Background

In recent years, rail trains develop rapidly in China, high-speed rail traveling has become the choice of most people, and related manufacturing industries also develop rapidly. The high-speed rail has a complex structure, a plurality of parts on the train are arranged, and the manufacture and detection of each part must be treated rigorously, so that an effective scheme is provided for the detection of the pedals on the train.

In the prior production factory, the detection of the upper pedal is limited to the detection of whether the upper pedal can be normally opened or closed by using an electromagnetic valve, the opening and closing time is visually observed by a worker and is not very accurate, and no relevant equipment can detect the upper pedal in the market, so the detection of the upper pedal is insufficient. In particular, the opening and closing of the upper pedals should be such that the actuation time of each pedal is approximately the same, which cannot be done with particular precision by manual means alone.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an go up footboard automatic timing alarm device to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the automatic timing alarm device for the upper pedal comprises the upper pedal, a change-over switch and a pneumatic solenoid valve, wherein the change-over switch is used for opening and closing the upper pedal by controlling the pneumatic solenoid valve, the upper pedal is composed of an upper pedal and a lower pedal, the upper pedal and the lower pedal are respectively connected with an indicator lamp in series, and the indicator lamp is connected with a relay and a timer in series.

Preferably, the input port of the timer IN1 is a timing start signal input, the input port of the IN2 is a timing stop signal input, and the output port of the OUT outputs an alarm signal represented by an indicator light H5.

Preferably, the action of the upper pedal to open the normally open contact and the normally closed contact is respectively represented by indicator lights H1 and H2, and the action of closing the normally open contact and the normally closed contact is respectively represented by indicator lights H3 and H4.

Compared with the prior art, the beneficial effects of the utility model are that: the time that all pedals of control that can be accurate closed and open reduces the error that causes by the manual work, avoids unnecessary loss.

Drawings

In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the description of the embodiments will be briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art that other drawings can be obtained according to the drawings without creative efforts.

Fig. 1 is a circuit diagram of the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the present invention provides a technical solution: the automatic timing alarm device for the upper pedal comprises the upper pedal, a change-over switch and a pneumatic solenoid valve, wherein the change-over switch is used for opening and closing the pedal by controlling the pneumatic solenoid valve, the upper pedal is composed of an upper pedal and a lower pedal, the upper pedal and the lower pedal are respectively connected with an indicator lamp in series, and the indicator lamp is connected with a relay and a timer in series.

It is noted that the timer IN1 has an input for a timing start signal, the timer IN2 has an input for a timing stop signal, and the timer OUT outputs an alarm signal, represented by an indicator light H5.

It is noted that the action of the upper pedal to open the normally open contact and the normally closed contact is respectively indicated by indicator lights H1 and H2, and the action of closing the normally open contact and the normally closed contact is respectively indicated by indicator lights H3 and H4.

Example (b):

assuming that the initial state of the equipment is a closed state, a knob is turned to an open state, the electromagnetic valve acts at the moment, an upper pedal is opened, meanwhile, a timer starts to time, after the upper pedal is completely opened, the timer stops timing by receiving a signal given by a proximity switch, and automatically judges whether the process time is within the time of 2-3 seconds, if the timer displays the used time within the time period, otherwise, a signal is given, a buzzer is triggered to give a warning, and the timer also displays the used time. At this time, the knob is turned to the 'off' state, the timer can restart timing, and the action process is completely the same as the opening process.

In the description herein, references to the description of "one embodiment," "an example," "a specific example" or the like are intended to mean that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the invention.
