The purpose of the utility model is to realize through following technical scheme:
A kind of large-scale hanging basket is used bont, comprises the casing that offers rope inlet and rope outlet, wherein; Rope sheave is installed in the said casing, and the top of said rope sheave is provided with connecting plate and presses rope mechanism, and said connecting plate presses rope mechanism to comprise the connecting plate that is articulated on the casing; Said connecting plate near the end hinged of rope inlet by rope mechanism; The other end corresponding to connecting plate is provided with swivel base, hinged side plate on swivel base, and the bottom of side plate is provided with wheel pressing shaft; Pinch roller is installed on wheel pressing shaft, and the pressure compensation mechanism that is articulated on the casing is equipped with on the top of said side plate and connecting plate hinged place.
Especially, said rope inlet is short shell-like, and rope outlet in a tubular form.
Especially, said pressure compensation mechanism comprises the upper and lower cover of spring, and the upper and lower cover inner sealing of said spring has spring, and an adjusting bolt is housed in the cover on the said spring, and spring is trapped and is enclosed within on the swivel base.
Especially, said connecting plate presses the lower end of rope mechanism to be provided with branch rope piece near the rope sheave place.
Especially, press rope mechanism and the vacancy position of dividing the rope piece to be furnished with the circular arc back-up ring corresponding to connecting plate on the cylindrical of said rope sheave.
The large-scale hanging basket of the utility model uses the beneficial effect of bont to be:
1) said connecting plate presses rope mechanism that the operation pressure of press rope wheel can be provided according to magnitude of load, and drives press rope wheel and be close to the steel rope outside face, is pressed in the rope sheave V-shaped groove, thereby promotes or the decline load;
When 2) said pinch roller operation pressure is excessive or not enough, can make it satisfying under the high condition of carrying, reduce the damage of steel rope widely, guarantee the stable normal of hoisting force through the adjustment pressure compensation mechanism.

The specific embodiment
Please with reference to Fig. 1 and shown in Figure 2, Fig. 1 is the structural representation of the large-scale hanging basket of the utility model with bont one embodiment; Fig. 2 is the large-scale hanging basket of the utility model is pressed rope mechanism with the connecting plate of bont a structural representation.
In present embodiment, described large-scale hanging basket comprises casing 3 with bont, and the both sides up and down of said casing 3 are offered the rope inlet 5 of upward opening respectively and to the rope outlet 1 of under shed; Said rope inlet 5 is short shell-like and may be stuck in the casing 3 upper circular holes, and said rope outlet 1 is fixedly installed in casing 3 bottoms in a tubular form, in the said casing 3 rope sheave 8 is installed; Said rope sheave 8 tops are provided with the connecting plate that is articulated in the casing 3 and press rope mechanism 6; Said connecting plate presses rope mechanism 6 to be provided with connecting plate 18, and the end hinged near rope inlet 5 of said connecting plate 18 leans on the mechanism 4 that restricts, and the other end of corresponding connecting plate 18 is provided with transposase 11 4; Hinged side plate 15 on transposase 11 4; The bottom of side plate 15 is provided with wheel pressing shaft 17, and pinch roller 16 is installed on wheel pressing shaft 17, and side plate 15 is equipped with pressure compensation mechanism 7 with the top of connecting plate 18 hinged places.
Said pressure compensation mechanism 7 is hinged with casing 3; Comprise spring 12, said spring 12 is closed on the spring cover 11 and spring and traps in 13, is equipped with one on the said spring in the cover 11 and regulates bolt 10; Said adjusting bolt 10 is articulated in the casing 3, and said spring is trapped and 13 is enclosed within on the transposase 11 4.
