Embodiment Construction
[0008] Such as figure 1 , 2 As shown, the rope-pressing seat 2 embedded in the surface of the reel, the upper surface of the rope-pressing seat 2 is a circular arc flush with the surface of the reel, and a through-hole 3 is drilled in the rope-pressing seat 2, and the transverse direction of the through-hole 3 The upper part of the section is rectangular, and the lower part is arc-shaped. Several countersunk threaded holes 5 distributed along the axial direction of the through hole are drilled on the upper surface of the rope pressing seat 2, and a rope pressing plate 4 extending axially along the through hole 3 is arranged in the through hole 3, and the cross section of the rope pressing plate 4 is rectangular , and its lower end face is milled with arc-shaped grooves. The countersunk threaded hole 5 internally threaded connection end is against the screw 1 of the rope pressing plate 4 .
[0009] During use, under the action of the screw 1, the arc-shaped groove on the low...

The invention relates to a winch rope pressing structure comprising a winding drum. A rope pressing seat is embedded in the surface of the winding drum, the upper surface of the rope pressing drum is a circular arc flush with the surface of the drum, a through hole is drilled in the rope pressing seat, a plurality of countersunk threaded holes distributed axially along the through hole are drilled in the upper surface of the rope pressing seat, and a rope pressing plate extending axially along the through hole is arranged in the through hole. The innovations include that the upper portion of a cross section of the through hole is rectangular, and the lower portion of the cross section of the through hole is circular arc shaped; a cross section of the rope pressing plate is rectangular, and a circular-arc-shaped groove is milled in the lower end face of the rectangular rope pressing plate. Screws are connected in the countersunk threaded holes in a threaded manner, the screws butt against the rope pressing plate, a rope head is clamped by matching of the circular-arc-shaped groove of the rope pressing plate and the circular arc of the lower portion of the through hole, connection is firm and reliable, and the rope head is prevented from being scratched; since the rope pressing plate and the upper portion of the through hole are both rectangular, when the screws butt against the rope pressing plate, the rope pressing plate moves downwards along the rectangular upper portion of the through hole without deflection.
Description
technical field [0001] The invention relates to a winch, in particular to a rope-pressing structure of a multi-rope winch. Background technique [0002] The rope head assembly of the traditional hoist is set on the drum and protrudes from the surface of the drum, which affects the normal winding of the rope. At present, there is a kind of rope pressing structure. The surface of the reel is embedded with a rope pressing seat. The upper surface of the rope pressing seat is an arc shape flush with the surface of the reel. Several countersunk threaded holes distributed along the axial direction of the through hole are drilled. The rope end is passed in the through hole, and is compressed by a screw threaded with the countersunk threaded hole. The disadvantages of this structure are: the screw is easy to scratch the extension head, the fixed part is reliable, and the sliding rope is easy to appear after long-term use of pulling. Contents of the invention [0003] The technic...
