Embodiment
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further specified below in conjunction with accompanying drawing and embodiment.Embodiment described herein only is used for explaining the present invention, and it is novel not to be used for limiting this use.
Before explanation chain roller sleeve disappearance of the present invention pick-up unit, the structure of roller chain in the first brief description prior art.As depicted in figs. 1 and 2, roller chain mainly comprises outer plate 1, interior sheet 2, bearing pin 3, sleeve 4 and roller 5, and wherein: sleeve 4 is enclosed within on the bearing pin 3; Roller 5 is enclosed within on the sleeve 4; Interior sheet 2 is connected from both sides with two bearing pins 3 that are with sleeve 4 and roller 5, thereby forms a chain link plate, and the distance between this two bearing pin 3 is called the chain link pitch; Outer plate 1 connects from both sides with the adjacent bearing pin 3 of two adjacent link; Thereby two adjacent link are connected, and chain link extends to both sides in a manner described, finally forms chain.
Next explanation; Chain roller sleeve disappearance pick-up unit provided by the present invention like Fig. 3 and shown in Figure 4, comprises pedestal 6 and lever 7; The fulcrum 8 of lever 7 is arranged on the pedestal 6; One end of lever 7 is provided with detection head 9, and detection head 9 has and is used for the surface of contact 10 that contacts with chain to be detected, and the other end of lever 7 is provided with displacement induction installation 14; The distance that displacement induction installation 14 and fulcrum are 8 is greater than the distance of 8 at detection head 9 and fulcrum, also is provided with the flexible member 11 that the surface of contact 10 that makes detection head 9 and chain to be detected closely contact on the lever 7.
Chain roller sleeve disappearance pick-up unit of the present invention; Displacement induction installation on its lever and the distance between fulcrum are greater than the distance between detection head and fulcrum; Make the displacement induction installation responsive to discover the micro-displacement of the detection head that amplified by lever; Therefore this pick-up unit not only can replace manual detection, and accuracy of detection is high, the false retrieval omission can not occur.
More accurate for the detection that makes detection head 9, the length of surface of contact 10 is more preferably greater than a chain link plate pitch, and preferably less than two chain link plate pitches.
In addition, displacement induction installation 14 preferably includes and receives sensing element 12 and photoelectric sensor 13, be arranged on the lever 7 by sensing element 12, and photoelectric sensor 13 is arranged on and receives on the sensing element 12 corresponding positions.At this moment, receive sensing element 12 and detection head 9 as shown in Figure 3, be in the relative both sides of lever 7, when receiving sensing element 12 near photoelectric sensor 13, displacement induction installation 14 detects displacement; And simultaneously, receive sensing element 12 and detection head 9 also can be separately positioned on the same side of lever 7, when receiving sensing element 12 away from photoelectric sensor 13, the displacement induction installation detects displacement accordingly.Particularly, receive sensing element 12 can be screw.
One skilled in the art will appreciate that the displacement induction installation except can adopting above-mentioned implementation, can also adopt to be all contactless displacement synchronous device that perhaps the displacement induction installation of contact repeats no more here.
In addition; Chain roller sleeve disappearance pick-up unit of the present invention can also comprise PLC controller and the motor of carrying chain to be detected; Wherein: the signal output part of photoelectric sensor 13 can be connected to the PLC controller, and the control end of this PLC controller can be connected to motor.When the displacement induction installation detected displacement, photoelectric sensor 13 sent signal to the PLC controller, and PLC controller control motor stops chain.
Simultaneously, the PLC controller can also be connected with alarm.When the PLC controller is received the signal of photoelectric sensor 13, can make alarm equipment alarm.Simultaneously, this alarm can directly be connected with photoelectric sensor 13, thereby photoelectric sensor 13 can directly make alarm equipment alarm.Particularly, alarm is preferably acousto-optic formula alarm.
Except above-mentioned points, in order to help finding fast and deal with problems, the PLC controller can also be connected with the control device of band display screen.When the PLC controller was received the signal of photoelectric sensor 13, the control device of screen to be shown can demonstrate detected problem rapidly.
In addition, under the surface of contact that does not influence detection head 9 10 and situation that chain to be detected closely contacts, according to the position that is provided with of flexible member, flexible member 11 can be extension spring or compression spring.Simultaneously also can replace flexible member 11 with press member.
In sum, when roller chain occurs like Fig. 5 or shown in Figure 6 when lacking the situation of roller or sleeve, under the effect of flexible member 11, detection head 9 still makes great efforts surface of contact 10 is adjacent to chain to be detected, thereby is subjected to displacement; And this displacement is through the amplification of lever 7; Make the sensing element 12 that receives of displacement induction installation that bigger displacement take place; Thereby help the detection of photoelectric sensor 13, finally improved the accuracy of detection of chain roller sleeve disappearance pick-up unit of the present invention, the false retrieval omission can not occur.
The above is merely preferred embodiment of the present invention, is not to be used for limiting practical range of the present invention; If do not break away from novel spirit of this enforcement and scope, make amendment or be equal to replacement this enforcement is novel, all should be encompassed in the middle of the protection domain of claim of the present invention.
