Description
Technical field
The utility model relates to a kind of access panel safety hit opening apparatus on escalator or moving sidewalk.
Background technology
Chinese National Standards GB 16899-2011 " manufacture and the installation safety standard of escalator and the moving sidewalk " access panel defined on escalator and moving sidewalk should arrange the electric safety device conformed with the regulations, otherwise can cause safety misadventure.At present, the access panel on original escalator or moving sidewalk is opened safety device and is relied on lever principle, and utilize Action of Gravity Field on safety switch, complex structure, fitting operation is poor, and onsite application failure rate is high.
Summary of the invention
In view of this, in order to overcome the defect of prior art, the purpose of this utility model be to provide a kind of structure simpler, easy for installation, use the access panel on more failure-free escalator or moving sidewalk to open safety device.
For achieving the above object, the utility model by the following technical solutions:
Access panel on a kind of escalator or moving sidewalk opens safety device, comprise can open or close access panel, be fixedly installed on base below described access panel, be fixedly installed on the safety switch sending after described base can be touched and stop described escalator or moving sidewalk run signal, it is characterized in that: described access panel safety device also comprises the push rod that can be arranged on up and down on described base, and be arranged between described base and described push rod and make described push rod have the elastic component upwards ejecting trend; Described access panel has open mode and closed condition, and when described access panel is in closed condition, described access panel pushes down the upper end of described push rod, and the contact of described push rod and described safety switch is separated, and described safety switch is not touched; When described access panel is in open mode, described push rod upwards ejects, described push rod and described safety switch inconsistent, described safety switch is touched.
Preferably, described access panel is opened safety device and is also comprised and being connected on described push rod to touch the baffle plate of the contact of described safety switch.
Further preferably, the upper and lower of described base is also respectively equipped with guide plate, and described push rod can be located in described guide plate up and down.
Further, described push rod is thread rod, and described baffle plate is fixed on the middle part of described push rod by lock nut.
Particularly, described elastic component is connected to described lock nut and between the guide plate of the bottom of described base.Elastic component is preferably Compress Spring.After access panel is opened, the elastic acting force of Compress Spring makes push rod upwards eject.
Wherein, the bottom of described push rod is also provided with limiting section, and when described push rod ejects, described limiting section is kept out on the described guide plate of the bottom in described base in place.Limiting section can prevent ejecting apart from excessive of push rod, and when avoiding described access panel to be in open mode, the excessive push rod that makes of the elastic force of elastic component departs from base and damages safety switch.
Particularly, described limiting section is the adjusting nut be threaded with described push rod.
For the ease of adjusting the setting height(from bottom) of base, described base offers the oval hole that its length extends the setting height(from bottom) adjusting described base along the vertical direction.
The utility model by elastic component drive push rod upwards eject, when access panel is opened, the push rod of automatic ejection can touch safety switch, make escalator or moving sidewalk out of service; When access panel closes the bar that bears down on one at present, after overcoming elastic component application force, push rod moves downward disengaging safety switch, makes escalator or moving sidewalk enter normal operating condition.Utilize the pressure rod structure of lever principle compared to tradition, whole apparatus structure of the present utility model is simpler, installs more convenient, works also more reliable.
Accompanying drawing explanation
Fig. 1 is that the utility model is in closed condition at access panel, structural representation when safety switch is not touched.
Fig. 2 is that the utility model is in open mode at access panel, structural representation when safety switch is touched.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
Refer to Fig. 1 and 2, access panel on escalator or moving sidewalk opens a safety device, comprise can open or close access panel 5, be fixedly installed on base 9 below access panel 5, be fixedly installed on to send after base 9 can be touched and stop described escalator or the safety switch 1 of moving sidewalk run signal, the push rod 8 that can be arranged on up and down on base 9, be arranged on the elastic component 13 making push rod 8 have between base 9 and push rod 8 upwards ejecting trend.
Base 9 offers the oval hole that its length extends along the vertical direction, bolt 6 is through on the truss 4 be fixed on by base 9 behind this oval hole on escalator or moving sidewalk.By the setting height(from bottom) of oval hole adjustable base 9.
The upper and lower of base 9 is fixed with guide plate 7 respectively, and push rod 8 can freely up and down be located in the guide plate 7 of upper and lower actively.The middle part of push rod 8 is connected with the baffle plate 11 of the contact touching safety switch 1.In the present embodiment, push rod 8 adopts thread rod, and baffle plate 11 is fixed on push rod 8 by upper and lower two lock nut 10.Elastic component 13 is connected between the guide plate 7 of the lock nut 10 of baffle plate 11 lower end and the bottom of base 9, the present embodiment Elastic part 13 adopts the Compress Spring be socketed on push rod 8, after access panel 5 is opened, the application force being pressed in push rod 8 upper end disappears, and the elastic acting force of elastic component 13 makes push rod 8 upwards eject.
Safety switch 1 is fixed on base 9 by bolt assembly 2 and thread plate 3, and safety switch is positioned at the outside of push rod 8, and when push rod 8 upwards ejects, baffle plate 11 touches safety switch 1.
Access panel 5 has open mode and closed condition, when access panel 5 is in closed condition, as shown in Figure 1, access panel 5 pushes down the upper end of push rod 8, baffle plate 11 on push rod 8 is separated with the contact of safety switch 1, safety switch 1 is not touched, and now escalator or moving sidewalk are in normal operating condition.When access panel 5 is in open mode, as shown in Figure 2, push rod 8 upwards ejects, and the baffle plate 11 on push rod 8 is inconsistent with safety switch 1, and safety switch 1 is touched, and sends the signal stopping escalator or moving sidewalk to run, guarantees the safety of service personnel.
The bottom of push rod 8 is also provided with limiting section 12, and when push rod 8 ejects, limiting section 12 is kept out on the guide plate 7 of the bottom being positioned at base 9, as shown in Figure 2.Limiting section 12 can prevent ejecting apart from excessive of push rod 8, and when avoiding access panel 5 to be in open mode, the excessive push rod 8 that makes of the elastic force of elastic component 13 departs from base 9 and damages safety switch 1.In the present embodiment, limiting section 12 is the adjusting nut be threaded with push rod 8.
As can be seen here, push rod when the utility model employing ejects, to touch safety switch, is made push rod more easily by the elastic force effect of elastic component and is reliably ejected, and just can touch safety switch immediately, ensure that the safety of service personnel after ensureing to open access panel.And the push rod that the utility model adopts up-and-down movement to arrange, structure is simpler, and it is also easier to install, and operates more convenient.
Above-described embodiment is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and implement according to this; protection domain of the present utility model can not be limited with this; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
