Description

Passenger conveyors

Technical field

Embodiment of the present utility model relates to passenger conveyors.

Background technology

Passenger conveyors is a kind of by multiple step loop connecting, the device of loopy moving between stopping port.

When maintenance inspection etc., in the driving of passenger conveyors, when step is to fishback is close and when declining gradually, step roller bearing getaway and situation about coming off also are contemplated.If step comes off, there will be step peristome.When operating personnel do not perceive step peristome and just in operation, operating personnel may fall from step peristome.The publication publication of Japan is had, Unexamined Patent 10-279246 publication (hereinafter referred to as patent documentation 1) as such technology.

Utility model content

Before, according to the record in patent documentation 1, we know so a kind of operation safety device, and it foreign matter folded in the movable part of escalator removing, and removes obstacles fast.But, also there is not the appearance the passenger conveyors stopping step driving that detect step peristome, expect to develop this passenger conveyors.

The purpose of this utility model can detect because step to come off etc. and the peristome occurred the passenger conveyors stopping step driving to provide.

In order to reach above-mentioned purpose, the feature of embodiment of the present utility model is, comprising: multiple steps of loopy moving, the apron guar plate arranged in the left and right sides along the moving direction of multiple step between stopping port of loop connecting and arrange in apron guar plate, this peristome can be detected when step comes off and occurs step peristome and generate the testing tool of peristome detection signal.

Detailed description of the invention

Below, detailed description of the invention of the present utility model is explained with reference to accompanying drawing.In addition, although below to be applicable to passenger conveyors of the present utility model, show and to be connected by multiple step and stepped moving up and down and the escalator of passenger-carrying levels, but the utility model also effectively can be applicable to be connected by multiple step and move in the horizontal direction and the automatic walkway of passenger-carrying (electronic pavement).

As shown in Figure 1, the escalator 1 of present embodiment is across setting up left and right sides pair of armrests plate 3 by the truss (not shown) of building fixed pedestal between upper strata and lower floor, in the Width both sides of this balustrade panel 3, be provided with multiple step 5.Around balustrade panel 3, the handrail 7 with the movement of multiple step 5 synchronous circulating is installed.In the position relative with the step 5 below balustrade panel 3, the moving direction along multiple step 5 is provided with apron guar plate 9.Between balustrade panel 3 and apron guar plate 9, cover inner cover plate 11, in addition, in the outside of balustrade panel 3, be provided with outer cover plate 15.

At each stopping port place of levels, be provided with lifting board 17, between lifting board 17 and step 5, be provided with fishback 19.In addition, on the apron guar plate 9 near stopping port, be provided with operation screen 21, in operation screen 21, be provided with buzzer stop 23 and upper and lower change-over switch etc.

In the truss of the inboard of lifting board 17, be provided with machine room 25.In machine room 25, be provided with control panel 27 and controlled by this control panel 27 drive sprocket is rotated and drives the CD-ROM drive motor 29 etc. of step 5.

In the present embodiment, especially, apron guar plate 9 is provided with the opto-electronic pickup 31 be made up of luminous element 31a and photo detector 31b.Such as, when the step 5 near stopping port falls to causing occurring step peristome 33, opto-electronic pickup 31 can detect, and when step 5 falls and occurs step peristome 33, opto-electronic pickup 31 is to control panel 27 outlet opening portion detection signal.

As shown in Figure 2, the setting position of opto-electronic pickup 31, is suitable for being arranged in the apron guar plate 9 of distance fishback 19 front end about 400mm (distance a, 350-450mm).Because, such as, when step 5 is close to fishback 19 and when declining gradually, step roller getaway and the situation etc. that causes step 5 to come off has been thus occur that the situation of step peristome 33 is more.In addition, as shown in Figure 3, the height and position set by opto-electronic pickup 31 is to detect the position that step 5 falls to being formed step peristome 33.

Control panel 27 is connected by signal wire (SW) 35a with opto-electronic pickup 31, when from opto-electronic pickup 31 outlet opening portion's detection signal, CD-ROM drive motor is stopped, and the driving of step 5 will stop.But, consider the situations such as error detection, such as, when peristome detection signal continues output more than 1 second, can think that step 5 comes off and occurs step peristome 33.

Buzzer stop 23 in operation screen 21, i.e. sound buzzer switch or alarm switch, be connected to control panel 27 by signal wire (SW) 35b.When operator wishes switchover operation direction (b), or wish by drive side to the situation stopping side operating, otherwise and, when being operated by stopping side direction drive side, buzzing will be sounded and be informed this situation.

Fig. 4 shows the diagram of circuit of the treatment step of embodiment of the present utility model.

After escalator 1 is driven, from the luminous element 31a irradiating and detecting light of opto-electronic pickup 31.Because step 5 is by the position of configuration opto-electronic pickup 31, so there is not step peristome under normal circumstances, step 5 has blocked detection light, and photo detector 31b can not receive and detect light (NO of step S1).When photo detector 31b receives detection light, will recognize that step 5 falls and forms step peristome 33, to control panel 27 outlet opening portion detection signal (YES of step S1).

When detect send more than 1 second from the peristome detection signal of opto-electronic pickup 31 (YES of step S3), it not error detection, but as there is the situation of step peristome 33, make escalator 1 (step S5) out of service.When the peristome detection signal from opto-electronic pickup 31 sent less than 1 second, by being judged as that the possibility of error detection is high, not making escalator out of service, proceeding the check processing (NO of step S3) of step peristome 33.

Stop the operation of escalator 1, step 5 is arranged on normal position, repair step peristome 33 etc., after completing safety verification work, the buzzer stop 23 being operated operation screen 21 by operating personnel makes buzzing sound, once by resetting escalator 1 (step S7), escalator 1 may be made to rerun.Then, an opto-electronic pickup is closed.By this method, recover the function of the safety return circuit of control panel 27, opto-electronic pickup 31 restarts the check processing (step S9) of step peristome 33.

Like this, according to embodiment of the present utility model, though when without monitor run, also automatically can detect to come off etc. for the appearance of the step peristome 33 of cause with step 5.Because make escalator 1 stop at once when step peristome 33 being detected, so can prevent trouble before it happens to the accident appearing as cause with step peristome 33.

In addition, in present embodiment, although opto-electronic pickup is arranged in the apron guar plate 9 of distance fishback 19 front end about 400mm, but this is not restriction, opto-electronic pickup also can be arranged on the suitable location between levels, in addition, also in multiple position, all opto-electronic pickup can be set.According to such formation, be not only the peristome near stopping port, the peristome occurred near intermediate point also can be detected, and further increases safety.

As mentioned above, although be illustrated embodiments more of the present utility model, these embodiments are only for casehistory content of the present utility model, and are not intended to limit scope of the present utility model.Also the embodiment of these novelties can be implemented by other various ways.In the scope not departing from aim of the present utility model, various omission, replacement, change can be carried out to it.These embodiments and distortion thereof are contained in scope of the present utility model and aim, and meanwhile, the scope of patent application comprises described utility model and equivalent scope thereof.
