Especially, described shake-up parts comprise the shake-up screw rod, and corresponding described shake-up screw rod is offered mounting hole on connecting rod, described shake-up screw rod pass mounting hole by nut locking on connecting rod.
Especially, the pressure compensation mechanism that is articulated on the casing is equipped with on the top of described side plate and connecting plate hinged place, and described pressure compensation mechanism comprises the upper and lower cover of spring, and the upper and lower cover inner sealing of described spring has spring, and be equipped with one on the described spring in the cover and regulate bolt, spring is trapped and is enclosed within on the swivel base.
Especially, the two ends of described side plate all are equipped with axle, and two pinch rollers are installed on the side plate by axle.
The beneficial effects of the utility model are; compared with prior art described hanging basket is set up by touching the overload protection mechanism that screw rod and micro-switch are formed on by rope mechanism with the overload protection mechanism of bont; when working load increases; the tension force of steel rope also increases thereupon; must drive by the outside deflection angle of rope mechanism and increase; thereby make the contact of withstanding micro-switch by the shake-up screw rod of installing on the rope mechanism end connecting rod; make micro-switch output ct-off signal; and control electronic box by the output line input and cut off the electricity supply, thereby realize the overload power-off protection.Not only simple in structure, be easy to realize; And improved the safe reliability of bont greatly, guaranteed the safety of operation.
Description of drawings
Fig. 1 is the hanging basket that provides of the utility model specific embodiment 1 with the structural representation of bont;
Fig. 2 is the hanging basket that provides of the utility model specific embodiment 1 with the structural representation of the overload protection mechanism of bont.
The specific embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment.
See also illustrated in figures 1 and 2; in the present embodiment; hanging basket comprises casing 1 with the overload protection mechanism of bont in one; the both sides up and down of described casing 1 are offered the rope inlet 2 of upward opening respectively and to the rope outlet 3 of under shed; described rope inlet 2 is short shell-like and may be stuck in the casing 1 upper circular hole; described rope outlet 3 is fixedly installed in casing 1 bottom in a tubular form; in the described casing 1 rope sheave 4 is installed; described rope sheave 4 tops are provided with the connecting plate 5 that is articulated in the casing 1; one end hinged one of the close rope inlet 2 of described connecting plate 5 is by rope mechanism; lean on rope sheave support 6 described comprising by rope mechanism; be installed on by on the rope sheave support 6 by rope sheave 7 and return dish spring 23; the described rope sheave support 6 that leans on is provided with connecting rod 8; offer mounting hole on the described connecting rod 8, shake-up screw rod 9 passes mounting hole and lock onto on the connecting rod 8 by nut 10.The corresponding screw rod 9 that touches is equipped with micro-switch 11 on connecting plate 5, described micro-switch 11 is electrically connected with electric cabinet 13 by signal wire (SW) 12.
The other end of described connecting plate 5 is provided with transposase 11 4, hinged side plate 15 on transposase 11 4, and the two ends of described side plate 15 all are equipped with 16, two pinch rollers 17 of axle and are installed on the side plate 15 by axle 16.Described side plate 15 is equipped with pressure compensation mechanism with the top of connecting plate 5 hinged places, described pressure compensation mechanism comprises spring 18, described spring 18 is closed on the spring cover 19 and spring and traps in 20, be equipped with one on the described spring in the cover 19 and regulate bolt 21, described adjusting bolt 21 is articulated in the casing 1, and described spring is trapped and 20 is enclosed within on the transposase 11 4.
