Detailed description of the invention
It should be noted that, in the situation that not conflicting, the feature in embodiment and embodiment in the utility model can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
As depicted in figs. 1 and 2, the 16 rope grip buckets that the utility model specific embodiment proposes are provided with supports rope 1, closed rope 11, entablatrance casing 3, cross sill casing 6, strut 7, reinforcement assembly pulley and two symmetrically arranged bucket bodies 8, on bucket body 8, be provided with bucket tooth 9, reinforcement assembly pulley is provided with the top sheave group 4 and the downslide wheels 5 that cooperatively interact; The top of strut 7 and entablatrance casing 3 are hinged, and the bottom of the outside of bucket body 8 and strut 7 is hinged, and the inner side of bucket body 8 and cross sill casing 6 are hinged; Top sheave group 4 is arranged on entablatrance casing 3, and downslide wheels 5 are arranged on cross sill casing 6, and closed rope 11 is alternately walked around top sheave group 4 and downslide wheels 5, supports rope 1 to be connected with entablatrance casing 3; Wherein, (be the integral structure of clear demonstration 16 rope grip buckets, do not demonstrate all closure ropes 11 and support rope 1 in Fig. 1 and Fig. 2 completely, the quantity of closed rope 11 can clearly from Fig. 4 be found out to support rope 1 and the quantity of closed rope 11 to be respectively eight.)。While capturing material, emit and support rope 1 and closed rope 11, under Action of Gravity Field, grab bucket declines, the relative top sheave group 4 of downslide wheels 5 moves downward, bucket body 8 around and strut 7 between hinge-point outwards overturn, and then two bucket bodies 8 are opened, when bucket body 8 inserts after material, regain closed rope 11, downslide wheels 5 upward movements, ordering about bucket body 8 inwardly overturns, and then two bucket bodies 8 are drawn close, final plant closure (simultaneously material being grabbed in bucket body 8), then, regain simultaneously and support rope 1 and closed rope 11, whole grab bucket is with supporting rope 1 and the up motion of closed rope 11, and then material is mentioned.
This 16 rope grip bucket is supported rope 1 and eight closed ropes 11 by arranging eight, in the case of remaining closed rope 11 and supporting that the diameter of rope 1 is constant, can effectively increase the load-carrying ability of grab bucket, and then guarantee that grab bucket meets the needs of large-scale operation; In the situation that load-carrying ability is constant, the diameter of the closure rope 11 of this 16 rope grip bucket and support rope 1 is less, thereby is conducive to the manufacture difficulty of the accessory such as pulley, hoisting mechanism, reduces manufacturing cost, is also conducive to structural arrangement and maintaining.
As shown in Figure 3, in the present embodiment, the setting that is centrosymmetric of 4 reinforcement assembly pulleys, closed rope 11 one end are wrapped on reinforcement assembly pulley, and the other end is wrapped on the closed reel 12 of duplex; For guaranteeing two closed 11 actions simultaneously of restricting of same group, the closed reel 12 of duplex here adopts coaxial connection, synchronously driven double crosslinking drum.
As shown in Figure 3, support rope 1 to be divided into one group for two, and one end of every group of support rope 1 is wrapped in duplex and supports that on reel 13, the other end is connected on an angle of entablatrance casing 3, four groups of support ropes 1 connect respectively four angles of entablatrance casing 3; For ensureing the stress equalization of two support ropes 1 on the same group, supporting rope 1 and entablatrance casing 3 junctions that equalizer bar 10 can be set; As shown in Figure 7, equalizer bar 10 is with respect to the vertical line of centers symmetry of himself, and protruding under its bottom edge; On equalizer bar 10, be provided with the two ends that the first through hole 17, the second through hole 18 and third through-hole 19, the first through holes 17 and the second through hole 18 are symmetricly set on equalizer bar 10, third through-hole 19 is arranged on vertical line of centers and the position of close bottom edge; Concrete set-up mode as shown in Figure 2, supports rope 1 to be connected with the first through hole 17, the second through hole 18 respectively on the same group two, and entablatrance casing 3 is hinged with third through-hole 19.
For preventing closed rope 11 or supporting rope 1 to depart from cooperation position, guide rope device 2 and leading sheave 14 can be in position set; As shown in Figure 1, guide rope device 2 is set on entablatrance casing 3, makes closed rope 11 through guide rope device 2; Again as shown in Figure 3, after support rope 1 is walked around leading sheave 14, be connected with equalizer bar 10.
In the above-described embodiments, closed rope 11 can arrange with reference to figure 4 with the concrete canoe of top sheave group 4, downslide wheels 5.In order to have reduced the angle of inclination of steel rope and rope race, reduce the friction of steel rope and pulley edge, anti-dislocation preventing slot, make the operation of reinforcement assembly pulley more steady, the center shaft 16 of top sheave group is spatial intersecting with the center shaft 15 of downslide wheels to be arranged, and the angle that their projections on horizontal surface form is less than 10 degree.At least following two kinds of the concrete set-up modes of top sheave group 4 and downslide wheels 5:
1) as shown in Figure 5, the extended line of the center shaft 15 of four downslide wheels intersects and seals into prismatic, and the rotary centerline of the center of prismatic and bucket body 8 is positioned at same perpendicular.
2) as shown in Figure 6, the center shaft 15 of four downslide wheels be arranged in parallel, and the center shaft 15 of downslide wheels and the rotary centerline of bucket body 8 mutually vertical.
In addition, the utility model specific embodiment also proposes a kind of Grab, is provided with 16 above-mentioned rope grip buckets.Can know according to the advantage of above-mentioned 16 rope grip buckets, by 16 above-mentioned rope grip buckets are set, in the situation that remaining closed rope 11 and support rope 1 diameter, can greatly promote the load-carrying ability of Grab; Keeping load-carrying ability in the situation that, can reducing the manufacturing cost of Grab, and facilitating for structural arrangement and the maintaining of Grab.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
