Abstract
The utility model discloses a detection device for locking of a protection door. The detection device comprises an air cylinder fixedly connected with the protection door and a proximity switch. An air cylinder shaft is connected onto a piston rod of the air cylinder, a detection shoulder is arranged on the air cylinder shaft, and the free end of the air cylinder shaft is corresponding to a blind hole in a protection door lock lug. The proximity switch is fixed on the protection door and is used for detecting the position of the detection shoulder when the protection door is closed in place and locked. The detection device is simple in structure, reasonable in design, convenient to use, safe and reliable and capable of improving the device safety greatly and improving the work efficiency.
Description
Technical field
The utility model relates to a kind of checkout gear, is specifically related to a kind of protective door locking checkout gear.
Background technology
At present, the steel cord equipment that each steel cord industry is used both at home and abroad is all furnished with protective door, but the safe locking device of protective door Shortcomings all, whether the protective door closure that can only detect having puts in place, can not detect and lock; Whether can only detecting of having locks, but whether protective door can not be detected closed.If want to reach above-mentioned double effects, two approach switchs will be installed, detect respectively complex structure, poor stability; In equipment debugging process, the position of approach switch is all artificial adjusting in addition, thereby waste of manpower, material resources has reduced production efficiency, has also increased staff's burden.
Summary of the invention
The purpose of this utility model is exactly the defect existing for prior art, provides a kind of simple in structure, easy to use, safe and reliable, can improve the security performance of equipment, the protective door locking checkout gear that can increase work efficiency.
Its technical scheme is: protective door locking checkout gear, comprise the cylinder being fixedly connected with protective door, on the piston rod of described cylinder, be connected with cylinder axis, described cylinder axis is provided with detection shoulder, the free end of described cylinder axis is corresponding with the blind hole being fixed on protection door lock ear, described locking checkout gear also comprises and being fixed on protective door, when protective door closure puts in place and locks for detection of the approach switch of described detection shoulder position.
Described approach switch is fixed on protective door by support.
The utility model compared with prior art, has the following advantages: simple in structure, reasonable in design, easy to use, safe and reliable, greatly improved the security performance of equipment, and also improved operating efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the left view of Fig. 1.
The specific embodiment
See figures.1.and.2, protective door locking checkout gear, comprise the cylinder 1 being fixedly connected with protective door, on the piston rod of described cylinder 1, be connected with cylinder axis 2, described cylinder axis 2 is provided with and detects shoulder 3, the free end of described cylinder axis 2 is corresponding with the blind hole 5 being fixed on protective door 4 lock ears, and described locking checkout gear also comprises and being fixed on protective door 4, when protective door 4 closures put in place and lock for detection of the approach switch 6 of described detection shoulder 3 positions.During installation, after protective door 4 closures put in place, cylinder 1 is arranged on the position that can make cylinder axis 2 inject the blind hole 5 of protective door 4 lock ears, the other end of cylinder axis 2 can inject in the blind hole 5 of protective door 3 lock ears, and withstand protective door 4 and lock ears, now, approach switch 6 use supports are fixed on the position of the detection shaft shoulder 3 that cylinder axis 2 can just be detected.
Described approach switch 6 is fixed on protective door 4 by support.
When this device carries out work, when protective door 4 closures put in place and lock, approach switch 6 can just detect in 3, two actions of the detection shaft shoulder on cylinder axis 2 and lack any one action, and approach switch 6 just can't detect the detection shaft shoulder 3 on cylinder axis 2.The object of the detection shoulder 3 on described cylinder axis 2 for reaching approach switch 6 while only having protective door 4 closures put in place and lock, just can be detected, select the larger cylinder of stroke 1, while making protective door 4 closures put in place and lock, the stroke of the piston rod of cylinder 1 only has half left and right of cylinder 1 stroke.So, if protective door 4 closures put in place, cylinder axis 2 is not locked protective door 4, and cylinder axis 2 does not move while not putting in place, and approach switch 6 can't detect the detection shoulder 3 on cylinder axis 2; If protective door 4 does not have closure to put in place, cylinder axis 2 can run to the range of cylinder 1 under the promotion of cylinder 1, exceeds the detection range of approach switch 6.So this device has just reached the object that protective door safe locking detects.
The utility model is simple in structure, reasonable in design, easy to use, safe and reliable, has greatly improved the security performance of equipment, has also improved operating efficiency.
