Velocity limiter 100 has transmission mechanism 106.Transmission mechanism 106 is configured to the rotation of rope sheave 101 transmitted to the 1st testing agency's body 110 when rope sheave 101 rotates forward and do not transmit to the 2nd testing agency's body 120.In addition, transmission mechanism 106 is configured to the rotation of rope sheave 101 transmitted to the 2nd testing agency's body 120 when rope sheave 101 reverses and do not transmit to the 1st testing agency's body 110.
In the present embodiment, the 1st free-wheel clutch (one-wayclutch) 106A in power transmission line between the armature 111 that transmission mechanism 106 is located at rope sheave 101 and the 1st testing agency's body 110 by being situated between, and the 2nd free-wheel clutch 106B in power transmission line between the armature 121 being located at rope sheave 101 and the 2nd testing agency's body 120 that is situated between is formed.
In more detail, in the present embodiment, the 1st free-wheel clutch 106A is arranged at the central part of armature 111, and the 2nd free-wheel clutch 106B is arranged at the central part of armature 121.Free-wheel clutch is also called free gear (freewheel) etc., and this free-wheel clutch is by the rotation in a direction from input side to outgoing side transmission, but does not transmit the mechanism of rightabout rotation.
In the present embodiment, the 1st and the 2nd free-wheel clutch 106A, 106B is the free-wheel clutch that make use of ratchet device (ratchetmechanism), and it is formed as shown in Figure 6.
1st free-wheel clutch 106A is made up of ratchet gear (ratchetwheel) 106a and multiple drg (pawl) 106b.Ratchet gear 106a is arranged on the axle 103 of rope sheave 101, and drg 106b is installed on armature 111.The bearing 106c such as antifriction-bearing box (rollerbearing) are embedded into the hole set by central part of armature 111, are supported the axle 103 of rope sheave 101 by this bearing 106c.Bearing 106c allows the axle 103 of rope sheave 101 to rotate with the relative freely of armature 111.
The direction of being engaged to the front end of drg 106b with ratchet gear 106a by not shown spring (spring) is exerted a force to drg 106b.When axle 103 rotates to arrow Rb direction, drg 106b engages with ratchet gear 106a, and the rotation of the axle 103 of rope sheave 101 is transmitted to armature 111.When axle 103 rotates to arrow Ra direction, drg 106b slides on ratchet gear 106a, and the rotation of the axle 103 of rope sheave 101 is not transmitted to armature 111.2nd free-wheel clutch 106B has the formation identical with the 1st free-wheel clutch 106A.
In addition, free-wheel clutch is not limited to the power-transfer clutch that make use of ratchet device, also can be other forms of power-transfer clutch.Such as, the form similar with antifriction-bearing box can be used (such as, by spring (spring), the position that roller (roller) is engaging with foreign steamer cam face (camsurfaceofouterrace) is moved, and by the wedge effect of roller, relative foreign steamer or interior wheel can not displacements) free-wheel clutch.
Subsequently, the effect of velocity limiter 100 is described.
[during rising]
When car 6 rises, rope sheave 101 also synchronously rotates.The rotation of the rope sheave 101 of rotating forward is transmitted to the 1st testing agency's body 110 by above-mentioned transmission mechanism 106, but does not transmit to the 2nd testing agency's body 120.So the 2nd testing agency's body 120 does not rotate, and does not carry out action completely.
When extremely occurring and the speed of car 6 reaches the 1st rising hypervelocity VU1, the actuator 115 that the flyball 112 being carried out the 1st testing agency's body 110 of displacement by centnifugal force is installed contacts with the working component 114b of stopping switch 114.Thus, the power supply of towing machine 3 is cut off, and towing machine 3 is stopped.
[during decline]
When car 6 declines, the rotation of the rope sheave 101 of reversion is transmitted to the 2nd testing agency's body 120, does not transmit to the 1st testing agency's body 110.
When extremely occurring and the speed of car 6 reaches the 1st decline hypervelocity VD1, the actuator 125 that the flyball 122 being carried out the 2nd testing agency's body 120 of displacement by centnifugal force is installed contacts with the working component 114b of stopping switch 114.Thus, the power supply of towing machine 3 is cut off, and towing machine 3 is stopped.
Even if after towing machine 3 stops, car 6 does not also stop and accelerating further, when the speed of car 6 reaches the 2nd decline hypervelocity VD2, by centnifugal force flyball 122 further displacement significantly, thus, the working component 102a of rope clamping mechanism body 102 moves, rope clamping mechanism body 102 damp governor rope 13.Thus, governor rope 13 (not diagram) relatively car is pulled up, and consequently, via arm 12, safety tongs device 11 carries out action, and the decline of car 6 is stopped.
In the above-described embodiment, transmission mechanism 106 has: the 1st free-wheel clutch 106A, only carries out the rotation transmission between rope sheave 101 and the 1st testing agency's body 110 when the rotating forward of rope sheave 101; And the 2nd free-wheel clutch 106B, the rotation transmission between rope sheave 101 and the 2nd testing agency's body 120 is only carried out when the reversion of rope sheave 101.Thus, do not carry out testing agency's body non rotating of overspeed detection, do not carry out action.Thus, without the need to arranging the formation of the function being used for stopping out-of-run testing agency body in advance at testing agency's body, the formation of testing agency's body can be set simply, in addition, former testing agency body can be quoted hardly design modification.In addition, during in order to rise speed limit and decline time speed limit switching, without the need to carrying out the blocked operation activated.
In addition, the 1st testing agency's body 110 and the 2nd testing agency's body 120 non rotating when not carrying out speed limit action also fully stops, therefore, it is possible to extend the life-span of testing agency's body.
In addition, the 1st testing agency's body 110 formed as flyball type and the 2nd testing agency's body 120 rotate centered by common horizontal direction axis, so, velocity limiter 100 can be formed compactly overall, installation space can be suppressed less.In addition, speed limit can share stopping switch 114 with speed limit when declining when rising, components number and cost can be cut down.
