Abstract
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
The present invention relates to a kind of winch, particularly a kind of many fag ends winch is pressed rope structure.
Background technology
The fag end combination of tradition winch is arranged on reel, and protrudes mandrel surface, affects normal wiring.Occurred at present a kind of pressure rope structure, mandrel surface is embedded with presses rope seat, and the circular arc of the upper surface of pressure rope seat for flushing with mandrel surface, presses in the seat of restricting and be drilled with through hole, presses rope seat upper surface to be drilled with several countersunk head tapped bore along through hole axial distribution.Fag end is through in through hole, utilizes the screw in compression being threaded with countersunk head tapped bore.The shortcoming of this kind of structure is: screw easily scratches peak with heading, and fixed part is reliable, uses for a long time after pull, is prone to abseiling.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of many fag ends of connection failure-free winch and presses rope structure.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of winch is pressed rope structure, comprise reel, mandrel surface is embedded with presses rope seat, the circular arc of the upper surface of described pressure rope seat for flushing with mandrel surface, in described pressure rope seat, be drilled with through hole, described pressure rope seat upper surface is drilled with several countersunk head tapped bore along through hole axial distribution, is provided with along the axially extended rope guarding plate of through hole in described through hole; Its innovative point is: the cross-sectional plane top of described through hole is rectangle, and bottom is circular arc; Described rope guarding plate cross-sectional plane is rectangle, and is milled with arc-shaped slot in the lower surface of rectangle rope guarding plate.
The invention has the advantages that: at countersunk head tapped bore negative thread attaching screw, by screw, prop up rope guarding plate, utilize the arc-shaped slot of rope guarding plate and through hole bottom circular arc to coordinate clamping fag end, firm and reliable connection, avoids fag end to scratch; And rope guarding plate and through hole top are rectangle, when screw props up rope guarding plate, rope guarding plate moves down along the rectangle top of through hole, can deflection.
Accompanying drawing explanation
Fig. 1 is that lifting drum of the present invention is pressed rope front view.
Fig. 2 is that lifting drum of the present invention is pressed rope lateral plan.
The specific embodiment
As shown in Figure 1, 2, bag is embedded in the pressure rope seat 2 of mandrel surface, and the upper surface of pressing rope seat 2 is the circular arc flushing with mandrel surface, presses in rope seat 2 and is drilled with through hole 3, and the cross-sectional plane top of through hole 3 is rectangle, and bottom is circular arc.Press rope seat 2 upper surfaces to be drilled with several countersunk head tapped bore 5 along through hole axial distribution, be provided with along the axially extended rope guarding plate 4 of through hole 3 in through hole 3, rope guarding plate 4 cross-sectional planes are rectangle, and its lower surface is milled with arc-shaped slot.Countersunk head tapped bore 5 negative threads connect the screw 1 that end props up rope guarding plate 4.
During use, under the effect of screw 1, the lower surface arc-shaped slot of rope guarding plate 4 with press rope seat 2 bottom circular arc coordinates clamping fag end.
