The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail, can implements according to this with reference to the specification sheets literal to make those skilled in the art.
The utility model provides a kind of lifting machine falling stop device, and Fig. 1 is the structural representation that this falling stop device and lifting machine combine, and lifting machine mainly comprises: the column 2 of lifting machine main body (not shown) and the described lifting machine main body of support.By Fig. 1, lifting machine also comprises supporting frame group component 1, and the lifting machine main body can be at this supporting frame group component 1 interior up and down traveling priority under the effect of elevator group component 3 by column 2.Wherein elevator group component 3 comprises reductor and the screw mandrel that is connected to this speed reducer output shaft, column 2 bottoms are provided with nut structure, and this nut structure is set on the described screw mandrel, when reductor drives the screw mandrel rotation, will drive nut and move up and down, and then drive lifting machine rising or whereabouts.
Fig. 2 is the enlarged drawing that encloses position I among Fig. 1, expression be the working diagram of falling stop device described in the utility model when the falling stop guard mode, Fig. 3 just expression be the working diagram of falling stop device described in the utility model when non-falling stop guard mode.
As shown in Figure 2, falling stop device described in the utility model comprises: open slot, and it is arranged on the sidepiece of described column 2; Installation frame 8, it is arranged on a side of described column 2, and is fixed on the supporting frame group component 1; Limiting stopper 4, it is articulated on the described installation frame 8 by rotating shaft 6, and described limiting stopper 4 one sides have protrusion; And elastomeric element 5, the one end is connected to described installation frame 8, and the other end is connected to the opposite side of described limiting stopper 4, exerts pressure to described limiting stopper 4, so that described protrusion is conflicted in described open slot.
Described installation frame 8 has the space for the section's rotation within it of described limiting stopper 4; At least a portion of described limiting stopper 4 is for to be made by magnetic material.
Described falling stop device also comprises: electromagnet 7, and it is arranged on the described installation frame 8, is positioned at the opposite side of described limiting stopper 4; Power supply, it is to described electromagnet 7 power supplies, so that described electromagnet 7 produces magnetic force.
Described limiting stopper 4 is for to be made by iron material.
The sidepiece of described column 2 offers a plurality of open slots of arranging along the length direction of described column 2.
The bottom of described limiting stopper 4 is articulated in described installation frame 8, and a side on top has protrusion, and the opposite side on top is connected to the other end of described elastomeric element 5.
Described limiting stopper 4 comprises a cubical limiting stopper main body and the protrusion that is positioned at described limiting stopper main body one side, wherein, the parallel sided of described protrusion is in the side of described limiting stopper main body, the side of described protrusion is connected by a transition plane that tilts with a side of described limiting stopper main body, and between the side of described transition plane and described protrusion, and all seamlessly transit between the side of described transition plane and described limiting stopper main body, the upper surface of described protrusion obtains for the upper surface by described limiting stopper main body stretches out, and the junction of the side of described protrusion and the upper surface of described protrusion is the right angle.
Be provided with two electromagnet 7 on the described installation frame 8.
Described elastomeric element is Compress Spring 5.
The utility model realizes that the principle of lifting machine falling stop is that limiting stopper 4 protrusions are to conflict under the effect of Compress Spring 5 in the open slot of column 2 inboards all the time, although so in the course of the work unexpected landing of lifting machine, also can stop owing to the existence of limiting stopper 4 protrusions, thereby avoided being fallen by the object of lifting.
When up moving under the effect of column 2 at reductor, because installation frame 8 has the space for the section's rotation within it of described limiting stopper 4, and the side of limiting stopper 4 protrusions is connected by a transition plane that tilts with a side of limiting stopper main body, between the side of described transition plane and described protrusion, and all seamlessly transit between the side of described transition plane and described limiting stopper main body, add column 2 up mobile power be greater than the power that Compress Spring 5 imposes on limiting stopper 4 protrusions, so that the existence of limiting stopper 4 protrusions can't have influence on column 2 is up mobile.When column 2 up moves gradually, limiting stopper 4 protrusions can be automatically between each open slot and original position (being the side of protrusion and the parallel sided of mounting bracket) of travelling to and fro between under the effect of Compress Spring 5 on the column, when accident is landed in lifting machine is being worked engineering, so owing to the supporting role of limited location piece 4 protrusions can be avoided occuring by the personnel that fall and then cause of lifting object and the loss of property.
When column 2 needs to fall, can give electromagnet 7 energisings, under the effect of electromagnetic force, magnetic limiting stopper 4 is adsorbed on the electromagnet, makes limiting stopper 4 be transformed into the state of non-falling stop, and column 2 just can move down, and sees Fig. 3.
Although embodiment of the present utility model is open as above, but it is not restricted to listed utilization in specification sheets and the embodiment, it can be applied to the various fields of the present utility model that are fit to fully, for those skilled in the art, can easily realize other modification, therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend of describing.
