The specific embodiment

Below in conjunction with accompanying drawing, the preferred specific embodiment of the present invention is described.

Embodiment one

As shown in Figure 1, in the present embodiment, the grab bucket guide rope device comprises that the chassis 1 that offers the first through hole 11 on the end face, four rotations are arranged on the roller 2 on 1 one of them end face of chassis, the end face that definition chassis 1 is equipped with roller 2 is the upper surface, and then this guide rope device also comprises four supports 4 that are fixed on the upper surface and are used for connecting roller 2 and chassis 1.

Four rolling 2 circular array centered by the axis of the first through hole 11 distributes, the rotating shaft of two relative rollers 2 parallels setting, the rotating shaft of four described rollers 2 plane coplanar and its place parallels with the end face on chassis 1, and the grab bucket conductor rope is located in the rope guiding hole 3 of the second square through hole 12 that four rolling 2 surrounds and 11 formation of the first through hole.Conductor rope moves, and roller 2 rotates thereupon, utilizes friction of rolling to replace original conductor rope and by the cliding friction between the hole, the service life of having improved conductor rope.

Each support 4 is arranged between adjacent two rollers 2, each support 4 be two blocks of perpendicular straight plates 41 be put together and the intersection line of two blocks of straight plates 41 perpendicular to the upper surface, two blocks of straight plates 41 that the rotating shaft of roller 2 is adjacent rotate and connect and perpendicular to these two blocks adjacent straight plates 41.

Embodiment two

As shown in Figure 3, the grab bucket guide rope device comprises the chassis 1 that offers the first through hole 11 on the end face, be parallel to each other and be oppositely arranged on the One On The Chassis lower support frame 82, be rotatably connected on two bottom rollers between the lower support frame 82 pair, the end face that definition chassis 1 is equipped with lower support frame 82 is the upper surface, chassis 1 is positioned at lower support frame 82 belows, then this grab bucket also comprise two fixed mounts be located at two between the lower support frame 82 upper support frame 81 and be rotatably connected on two upper rollers between the upper support frame 81 pair.
