Example 1
Fig. 1 is a schematic view of a slack rope detection device 100 in embodiment 1 of the present invention in a state where a lifting rope 300 is tensioned; FIG. 2 is an enlarged view of portion II of FIG. 1; fig. 3 is a schematic view of the slack rope detection apparatus 100 according to embodiment 1 of the present invention in a state where the lifting rope 300 is slack. Referring to fig. 1 to 3, the present embodiment provides a slack rope detecting device 100 and a stacker (only a part of which is shown in the drawings), wherein the stacker includes a bridge 200, a lifting rope 300 with a fixed end connected to the bridge 200, the slack rope detecting device 100, and a power device (not shown in the drawings). The power device is used for moving the bridge 200, and the bridge 200 drives the fixed end (upper end) of the lifting rope 300 to move so as to lift or drive the object loaded at the hanging end (lower end) of the lifting rope 300. In this embodiment, a long screw 210 is fixedly disposed on the bridge 200, and the long screw 210 is fixed to the bridge 200 by a nut. As shown, the long screw 210 is in a hanging state, and a fixing member 220 is provided at a lower end thereof, and the fixing member 220 is used for connecting a fixed end of the lifting rope 300. Of course, in other embodiments of the present invention, the fixed end of the lifting rope 300 can be directly fixed to the bridge 200.
In this embodiment, the slack rope detecting device 100 includes a fixing base 110, a sensor 120 disposed on the fixing base 110, a trigger 130 movably connected to the fixing base 110, and an elastic member 140 connected between the fixing base 110 and the trigger 130. The trigger 130 is used to connect a portion between the fixed end and the hanging end of the hoist rope 300. Wherein, when the lifting rope 300 is tightened (shown in fig. 1), the trigger 130 can be driven by the lifting rope 300 to move to the trigger position of the trigger sensor 120; when the lifting rope 300 is slack (shown in fig. 2), the trigger 130 can be moved from the trigger position by the elastic member 140 to bias the lifting rope 300 from the tensioned position. It can therefore be appreciated that when the hoist rope 300 is tensioned, the sensor 120 is triggered; when the lifting rope 300 is slack, the lifting rope 300 can be swung open by the trigger 130, and the trigger 130 is also in a state of not triggering the sensor 120.
In this embodiment, the sensor 120 is a proximity switch, and when the trigger 130 moves to a trigger position of the proximity switch due to the tightening of the lifting rope 300, the proximity switch is turned to a trigger state and outputs a first signal; when the trigger 130 is not moved to the trigger position, the proximity switch is in the non-trigger state, and outputs the second signal or does not output the signal. It can be determined whether the hoist rope 300 is tensioned or slack by different signals of the sensor 120. Likewise, the sensor 120 may also be a travel switch. Of course, in this embodiment, since the lifting rope 300 is pulled by the trigger 130 when it is loosened and is deviated from the position when it is tightened, the operator can make a preliminary judgment on whether the lifting rope 300 is tightened or not by naked eyes. Compared with the prior art, the slack rope detection device 100 of the present embodiment is beneficial to obtaining more accurate detection results.
Of course, in other embodiments of the present invention, the sensor 120 may also be a photoelectric sensor, and determine whether the lifting rope 300 is in a tensioned state or a relaxed state by whether its light path is blocked by the trigger 130; or the sensor 120 may be a pressure sensor, and the data fed back by the pressure sensor is used to determine whether the lifting rope 300 is in a tensioned state or a relaxed state.
In this embodiment, the fixing base 110 is fixedly connected to the lower portion of the bridge 200, and the connection position of the trigger 130 and the lifting rope 300 is slightly lower than the fixed end of the lifting rope 300. As shown in fig. 1, the fixing base 110 may have a plate shape. Further, the trigger 130 is a rod, one end of which is hinged to the fixing base 110, and the other end of which is movably connected to the lifting rope 300.
In the embodiment, the triggering member 130 is rotatably connected to the fixing base 110, and the triggering member 130 can swing relative to the fixing base 110 under the action of the lifting rope 300 or the elastic member 140 to trigger or not trigger the sensor 120. As shown in fig. 1, the hanging rope 300 is in a hanging state when it is tightened, and the triggering member 130 swings downward by the force of the hanging rope 300 and moves to a triggering position, thereby triggering the sensor 120. As shown in fig. 3, when the hanging end of the lifting rope 300 loses load, it is transferred to a relaxed state. At this time, the trigger 130 receives the force of the elastic member 140, and the free end swings upward to push the lifting rope 300 away from the hanging position where the lifting rope 300 is tightened, so that the lifting rope 300 is deflected. At this time, since the trigger 130 has moved away from the trigger position, the signal output from the sensor 120 changes.
In order to make the trigger 130 swing upward more easily, further, a free end of the trigger 130 is provided with a collar 134, and the collar 134 is sleeved on the lifting rope 300 and can slide up and down relative to the lifting rope 300. This avoids the situation where the trigger 130 is fixedly connected to the lifting rope 300, and the upward swing would be a burden on the weight of the entire lifting rope 300.
In this embodiment, the elastic member 140 is a torsion spring, the trigger 130 is provided with a position-limiting portion 132, and the position-limiting portion 132 is in a shaft shape and perpendicular to the trigger 130. The torsion spring is sleeved on the hinge shaft of the trigger 130, one elastic arm of the torsion spring abuts against the fixing seat 110, and the other elastic arm of the torsion spring abuts against the limiting part 132 of the trigger 130, so that the torsion spring can drive the trigger 130 to swing upwards by using the elasticity of the torsion spring after the lifting rope 300 is loosened.
It can be seen from the above process that the maximum load of the elastic member 140 is only related to the trigger position, and not to the load of the lifting rope 300, so that the large lifting rope load does not cause damage to the elastic member 140.
Example 2
Fig. 4 is a schematic view of the slack rope detection apparatus 100 according to embodiment 2 of the present invention in a state where the lifting rope 300 is tensioned; FIG. 5 is an enlarged view of portion V of FIG. 4; fig. 6 is a schematic view of the slack rope detection apparatus 100 according to embodiment 2 of the present invention in a state where the lifting rope 300 is slack. Referring to fig. 4 to 6, the present embodiment provides a slack rope detecting device 100 and a stacker, the structures of which are substantially the same as those of the slack rope detecting device 100 and the stacker in embodiment 1, and the difference is that the structure and the arrangement manner of the triggering member 130 are different.

The trigger 130 can be moved along the axis of the mounting hole by the elastic member 140 or the lifting rope 300 to trigger or not trigger the sensor 120.
In the present embodiment, the elastic member 140 is a spring, and preferably in a compressed state. The trigger 130 is provided with a position-limiting portion 132, and the position-limiting portion 132 is axial and perpendicular to the trigger 130. The spring is sleeved on the trigger 130, and two ends of the spring respectively abut against the limiting portion 132 and the fixing base 110.
When the lifting rope 300 is tightened (shown in fig. 4 and 5), the elastic member 140 is compressed toward the fixing base 110, and the limiting portion 132 approaches the sensor 120 to trigger the sensor 120; after the lifting rope 300 is loosened, the elastic member 140 rebounds to push the triggering member 130 away from the triggering position of the triggering sensor 120, and the output signal of the sensor 120 changes. At this time, the lifting rope 300 is also offset from its original hanging position by the movement of the trigger 130.

Specifically, in this embodiment, a collar 134 is disposed at an end of the main shaft 136 away from the fixing base 110, and the collar 134 is sleeved on the lifting rope 300 and can slide relative to the lifting rope 300. The trigger 138 is rod-shaped and perpendicular to the main shaft 136, so that the trigger 138 swings to reach or leave the trigger position when the main shaft 136 rotates. The main shaft 136 is provided with an L-shaped limiting portion 132, the limiting portion 132 is closer to the fixing base 110 relative to the triggering portion 138, and the limiting portion 132 is used for abutting against the elastic member 140.
