Abstract
The utility model relates to a kind of staircase brake wear detection device, comprise friction plate and shell, friction plate and shell use pivot pin to be flexibly connected, shell is provided with friction film trap, enclosure is provided with rotor iron core, described friction plate is provided with bolt hole, friction plate is connected with wear detector, wear detector is made up of terminal box, brass bolt and feedback means, terminal box is connected to outside friction plate, brass bolt one end to be connected in bolt hole and do not exceed inside friction plate, the other end is connected with feedback means.When friction disc wear is serious, when can not carry out staircase normal brake application, brass bolt and rotor iron core conducting, make conjunction cable conducting, mainboard receives wear signal, and staircase can not be started.
Description
technical field:
The utility model relates to a kind of staircase brake wear detection device, belongs to staircase technical field.
background technique:
Along with the development of economic society, staircase is more and more used in turn station of megastore and subway public transport, as a kind of special traffic tool, its Security is inevitable extremely to be paid attention to, although staircase is the life of people bring facility, but the security incident again and again occurred also has beaten alarm bell to manufacturer, and staircase motor plays a part coherence, staircase is in daily use, the loss of band-type brake friction plate is often ignored by people, cause the distance of main frame in stagnant stopping excessive, when staircase occurs extremely stopping ladder, friction plate loss due to band-type brake is comparatively large and staircase can not be made to stop, cause descending situation of slipping car.
summary of the invention:
The technical problems to be solved in the utility model be to provide a kind of can detect staircase brake friction plate abrasion degree and when detect friction plate can not effective brake staircase cannot be run device.
In order to solve the problems of the technologies described above, the utility model provides a kind of staircase brake wear detection device, comprise friction plate and shell, described friction plate and shell use pivot pin to be flexibly connected, shell is provided with friction film trap, enclosure is provided with rotor iron core, described friction plate is provided with bolt hole, friction plate is connected with wear detector, described wear detector is by terminal box, brass bolt and feedback means composition, described terminal box is connected to outside friction plate, described brass bolt one end to be connected in bolt hole and not to exceed inside friction plate, the other end is connected with feedback means.
Further, be provided with through hole bottom terminal box, through hole and bolt hole center are apart from identical; brass bolt is through through hole; using nut to connect brass bolt is fixed on friction plate by terminal box, and outside increases terminal box both can protect internal wiring structure, was also that whole outward appearance device layout is more attractive in appearance simultaneously.
After adopting this structure, detected by the degree of wear of detection device to friction plate, when detecting that friction plate loss arrives certain degree, staircase just cannot continue to run, must more renewal of facing renewal, would not produce because friction plate loss is excessive like this and cause the situation that main frame can not stagnantly stop, thus ensure that the normal operation of elevator and the safety of passenger.
accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is the utility model friction plate mounting structure view.
Fig. 2 is the utility model terminal box installation structure view.
embodiment:
Below in conjunction with the drawings and the specific embodiments, the utility model is described in detail:
A kind of staircase brake wear detection device according to Fig. 1, Fig. 2, comprise friction plate 1 and shell 2, described friction plate 1 uses pivot pin to be flexibly connected with shell 2, shell 2 is provided with friction film trap 21, shell 2 inside is provided with rotor iron core 3, friction plate 1 is provided with bolt hole 11, friction plate 1 is connected with wear detector, wear detector is made up of terminal box 4, brass bolt 5 and feedback means 6, terminal box 4 is connected to outside friction plate 1, brass bolt 5 one end to be connected in bolt hole 11 and do not exceed inside friction plate 1, the other end is connected with feedback means 6.
Be provided with through hole 41 bottom terminal box 4 according to Fig. 2, described through hole 41 is identical with bolt hole 11 centre distance, and described brass bolt 5, through through hole 41, uses nut to connect brass bolt 5 and terminal box 4 is fixed on friction plate 1.
During use, break, when normal brake application, by the pressure of band-type brake wall upper spring, makes the friction plate 1 on band-type brake wall rub with the rotor iron core 3 of main frame, produces braking force and motor is shut down.Brake wear is a kind of device detecting friction plate 1 damage, and 2 brass bolts are connected friction plates 1, and one of brass bolt 5 fixing with the friction plate of braking, and the other end use nut of brass bolt connects, and for fixed cable, signal is connected to detection device.Main frame stagnantly to stop daily, and can consume the thickness of friction plate 1, make rubber tape slowly thinning, 2 brass bolts are through rotor iron core conducting, and make conjunction cable conducting, mainboard receives wear signal, and staircase can not be restarted.
It is emphasized that: be only preferred embodiment of the present utility model above, not any pro forma restriction is done to the utility model, every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
