This utility model relates to escalator safety guard field, particularly relates to a kind of escalator
Inlet of handrail vision anti-pinch detection device.
Background technology
In the public arenas such as the market that flow of the people is the biggest, escalator is requisite.Automatically holding up
The import and export that ladder rail band rolls have individual space, and this space just can put in the hands of child, once child
Hands extend in space and will be involved in thus damage accident, there is presently no corresponding anti-pinch
Detection device solves above-mentioned potential safety hazard.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of automatic staircase handrail band entrance vision and prevents
Folder detection device, simple in construction, compact, utilize illuminator to expand the visual line of sight of supervision, protect
Card escalator when there being foreign body to enter at inlet of handrail can stop in time.
This utility model solves its technical problem and be the technical scheme is that a kind of escalator of offer is held up
Hand strap entrance vision anti-pinch detection device, including mounting base and photographic head, described mounting base upper
Both sides are the most vertically-mounted mirror mount and camera head installation rack for end, described mirror mount interior
Being provided with the first illuminator on sidewall between two parties, the upper surface of described mirror mount is disposed with towards photographic head
The second illuminator that installing rack tilts, described photographic head is arranged on camera head installation rack upper end towards second
On the sidewall of illuminator.
Supplement as to the one of technical scheme described in the utility model, described mirror mount upper
End is the mirror installation portion that upper surface is inclined-plane, and the second described illuminator is arranged on the upper of mirror installation portion
On end inclined-plane, the lower end of this second illuminator oliquely downward extends to the height identical with photographic head.
Supplement as to the one of technical scheme described in the utility model, described camera head installation rack
Being provided with photographic head mounting blocks on the sidewall of upper end, described photographic head is arranged on photographic head mounting blocks.
The installation gap of U-shaped is had on the mounting base of described camera head installation rack lower end.
Further, the upper edge of the first described illuminator is higher than the lower edge of photographic head.
Beneficial effect
This utility model relates to a kind of automatic staircase handrail band entrance vision anti-pinch detection device, simple in construction,
Compact, utilizes illuminator to expand the visual line of sight of supervision, it is ensured that when having abnormal object near automatically
During escalator handrail porch, escalator can stop in time.

Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is expanded on further.Only should be understood that these embodiments
For this utility model being described rather than limiting scope of the present utility model.In addition, it is to be understood that reading
After the content that this utility model is lectured, this utility model can be made various changing by those skilled in the art
Moving or amendment, these equivalent form of values fall within the application appended claims limited range equally.
As Figure 1-3, embodiment of the present utility model relates to a kind of automatic staircase handrail band entrance and regards
Feel that anti-pinch detects device, including mounting base 7 and photographic head 1, the both sides, upper end of described mounting base 7
The most vertically-mounted have mirror mount 9 and camera head installation rack 2, the inner side of described mirror mount 9
Being provided with the first illuminator 6 on wall between two parties, the upper surface of described mirror mount 9 is disposed with towards photographic head
The second illuminator 4 that installing rack 2 tilts, described photographic head 1 is arranged on camera head installation rack 2 upper end court
On the sidewall of the second illuminator 4.
Supplement as to the one of technical scheme described in the utility model, described mirror mount 9
Upper end be upper surface be the mirror installation portion 5 on inclined-plane, the second described illuminator 4 is arranged on mirror installation portion
On the inclined-plane, upper end of 5, the lower end of this second illuminator 4 oliquely downward extends to the height identical with photographic head 1
Degree, makes photographic head 1 it can be seen that situation above rear side.
Supplement as to the one of technical scheme described in the utility model, described camera head installation rack 2
Upper end sidewall on photographic head mounting blocks 3 is installed, described photographic head 1 is arranged on photographic head mounting blocks 3
On, it is convenient for changing different photographic head mounting blocks 3 to adapt to different photographic head 1.
Further, the mounting base 7 of described camera head installation rack 2 lower end has the installation of U-shaped
Breach 8, is conveniently arranged on mounting base 7 on floor.
Further, the upper edge of the first described illuminator 6 is higher than the lower edge of photographic head 1, it is ensured that shooting
1 it can be seen that situation on rear side of photographic head 1.
The when of use, detection device being reversibly mounted on belt and is scrolled into the lower section of outlet, first is reflective
Mirror 6 and the second illuminator 4 are scrolled into the peripheral position of outlet both facing to belt, along with scientific information technology
Sending out fast development, software engineering is more ripe.Wherein image analyzing and processing technology is also widely applied
Photographic head 1 in every field, this patent was photographed by the first illuminator 6 and the second illuminator 4
Image can judge either with or without foreign body close to space, automatic staircase handrail band porch after the process of software
Just can produce stopping signal, stop the operation of escalator in time, prevent accident.
During software processes image, software can filter out the object that some are less, as being pasted onto
Chewing gum on belt, only just can send the signal of stopping when it detects the object of size as hands,
Prevent unnecessary jerk.
This utility model simple in construction, compact, utilize illuminator to expand the visual line of sight of supervision,
Ensure that elevator can stop in time when there being foreign body to enter in breach.
