Abstract
The utility model discloses an escalator step missing detection apparatus comprising fixedly arranged shoe plate, a rotary arm rotatably arranged on the shoe plate, a rolling component arranged at one end of the rotary arm and rotatably pressed against side surface of a step, an elastic component arranged between the rotary arm and the shoe plate and being capable of providing elastic restoring force for the rotary arm so as to rotate the rotary arm when a step is missing, and a contact switch fixedly arranged and being capable of being triggered by the rotating rotary arm and sending out signal to stop the operation of the escalator. When successive steps are present, the rolling component on the rotary arm stably presses against the side surfaces of the steps through the elastic component. A gap is arranged between the rotary arm and the contact switch. The escalator runs stably, when the contact switch is not triggered. When a step is absent, the rolling component presses against nothing, and the elastic restoring force of the elastic component drives the rotary arm to rotate. The contact switch is triggered, and sends out signal to stop running of the escalator. Compared with detection apparatus employing photoelectric probe, the detection apparatus made of mechanical components is low in cost, convenient for installation, and reliable for use.
Description
Technical field
the utility model relates to escalator step and loses detecting device.
Background technology
The step of
escalator is the movable parts that supplies the passenger to stand, and the step of escalator staircase when normal the use is arranged on the traction chain and in company with the chain cycle continuously.In fact, when repair and maintenance, will dismantle or some steps of escalator reinstalls step if the repair and maintenance personnel forget after repair and maintenance sometimes, and the step on chain is not to have arranged continuously just so, just neutral can occur.This moment, the passenger was in the process of using escalator, and very possible one rides into neutral, produces very serious safety misadventure.Whether have neutral step have just seem important, in the prior art, whether step loss detecting device generally adopts the form of photoelectric probe to detect has neutral if how to detect for this reason; Cost is than higher so on the one hand; On the other hand probe mounting is required very highly, the gap of probe and step can not too greatly can not be too little, exceeded the detection range of probe too greatly; Too little then easy and step generation collision causes the damage of probe.
Summary of the invention
The purpose of
the utility model provides mechanical type step loss detecting device on the escalator, when step exists, makes the rolling member on the pivot arm stably conflict in the step side through elastic component, and this moment, contact switch was not touched; When step was lost, the elastic-restoring force through elastic component made pivot arm rotate, and touched contact switch, and then escalator is out of service, and this mechanical detecting device cost is low, easy for installation, used reliable.
are for achieving the above object; The technical scheme that the utility model adopts is: escalator step is lost detecting device, an end that comprise the stay bearing plate that fixedly installs, rotate the pivot arm that is arranged on the said stay bearing plate, is arranged on said pivot arm can rollably conflict rolling member on the step side, be arranged on the elastic component that rotates that can provide this pivot arm elastic-restoring force to make step drive this pivot arm when losing between said pivot arm and the said stay bearing plate, the contact switch that stops said escalator operation signal is sent in the said pivot arm shake-up that fixedly installs and can be rotated then.
preferably, said elastic component adopts to be compressed in and makes the spring of the stable conflict of said rolling member on the step side between said pivot arm and the said stay bearing plate.
further preferably; Be set with guidepost on the said stay bearing plate; Offer perforation on the said pivot arm; Said guidepost can carry out the corresponding said perforation of passing movably along with said pivot arm rotates, and said guidepost is arranged with said spring on the position between said stay bearing plate and the said pivot arm.
Preferably, said stay bearing plate is fixedly installed on the truss of said escalator
.
Preferably, said contact switch is fixedly installed on the truss of said escalator through support
.
preferably, said rolling member adopts roller, the axial line of said roller and the rotational axis line of said pivot arm parallel, all along the above-below direction extension of said escalator.
as a kind of concrete embodiment, said roller has two, and two said rollers are arranged side by side up and down on said pivot arm, and said two roller coaxial inner conductors are provided with.
are because the utilization of technique scheme; The utility model compared with prior art has advantage: when the step continued presence; Make the rolling member on the pivot arm stably conflict on the side of step through elastic component; Have the gap between pivot arm and the contact switch, contact switch is not touched, the staircase smooth running; When step take place to be lost, rolling member did not have the parts that can conflict, and the elastic-restoring force of elastic component makes pivot arm rotate, and contact switch is touched, and sends signal and makes escalator out of service.This detecting device adopts that mechanical part is combined to form, and compare and adopt the detecting device of photoelectric probe with low cost, and easy for installation, use reliable.
Description of drawings
Accompanying drawing 1 is the schematic top plan view one of the utility model, wherein step continued presence;
Accompanying drawing 2 is the schematic top plan view two of the utility model, and wherein step is lost;
accompanying drawing 3 is the schematic side view of the utility model.
The specific embodiment
The structure of the utility model is further set forth in
below in conjunction with accompanying drawing.
are referring to shown in Fig. 1-3; Escalator step is lost detecting device, on the end that comprise the stay bearing plate 1 that fixedly installs, rotate the pivot arm 2 that is arranged on the stay bearing plate 1, is arranged on pivot arm 2 and the rolling member 3 on step 7 sides of can rollably conflicting, be arranged on the elastic component 4 that can provide pivot arm 2 elastic-restoring forces to make that driven in rotation arm 2 rotated when step was lost between pivot arm 2 and the stay bearing plate 1, the contact switch 5 that stops this escalator operation signal is sent in pivot arm 2 shake-up that fixedly install and can be rotated then.When the step continued presence, as shown in Figure 1, rolling member 3 is conflicted and on the side of step 7, is constantly rolled, and elastic component 4 is in impaction state, has the gap between pivot arm 2 and the contact switch 5, and contact switch 5 is not touched; When step took place to lose, as shown in Figure 2, rolling member 3 broke away from the side of step 7; Lacked the parts that can conflict, the restoring force of elastic component 4 makes pivot arm 2 rotate, and pivot arm 2 rotates and makes its top touch contact switch 5; Thereby send signal, this escalator is out of service.This detecting device adopts that mechanical part is combined to form, and compare and adopt the detecting device of photoelectric probe with low cost, and easy for installation, use reliable.
are referring to shown in Fig. 1-2; Elastic component 4 adopts to be compressed in and makes rolling member 3 stablize the springs of conflicting on step 7 sides between pivot arm 2 and the stay bearing plate 1; The fixing guidepost 6 that is provided with on the stay bearing plate 1; Offer perforation on the pivot arm 2, guidepost 6 can carry out the corresponding above-mentioned perforation of passing movably along with pivot arm 2 rotates, and above-mentioned spring promptly is set in guidepost 6 on the position between stay bearing plate 1 and the pivot arm 2.
