Abstract
The utility model discloses a transition block used for a winding type hoister. The inner end surface and the outer end surface of the transition block are circular-arc-shaped, the thickness of the transition block is increased gradually from a rope inlet end to a rope outlet end, a boss is arranged in the middle at one side of the transition block along the edge of the inner end surface of the transition block, the thickness of the boss is increased gradually and the height of the boss is reduced gradually from the rope inlet end to the rope outlet end, and a rope slot connected with the boss is arranged at one side of the rope outlet end along the edge of the inner end surface of the rope outlet end. When a steel wire rope is wound on the winding drum, the direction of the steel wire rope can be changed conveniently, simultaneously, the breakage of the steel wire rope caused by the severe friction between the steel wire rope and the winding drum can be avoided, the service life of the steel wire rope is prolonged, and the safety performance of the hoister is improved.
Description
Technical field
The utility model relates to a kind of transition block of gig, a kind of specifically transition block that is used for cylindrical drum hoist.
Background technology
Employed cylindrical drum hoist in the existing market, all be that steel rope is fixed on the reel, the other end is walked around head sheave and is linked to each other with lifting container, when reel rotates, steel rope twines on reel or emits, drive the lifting container lifting, thereby carry out work, this kind method, not transition apparatus, when work, cause steel rope when change of direction twines, must could force the steel rope change of direction by drum wall, the method causes steel rope to form violent shearing with drum wall in change of direction, makes wire cable rupture easily, seriously shortens the service life of steel rope, also reduce the safety performance of gig, and then caused the human resources waste.
Summary of the invention
The utility model provides a kind of transition block that is used for cylindrical drum hoist for addressing the above problem, and is convenient to protect steel rope not to be worn, and is beneficial to steel rope change of direction in the course of the work, have simple in structure, be convenient to characteristics such as fitting operation.
The technical scheme that the utility model adopted is: a kind of transition block that is used for cylindrical drum hoist, be circular arc at transition block inner end surface and outer face, the thickness of transition block increases gradually from the rope-in end to the rope-out end, edge at the middle part of transition block one side along inner end surface is provided with boss, the thickness of boss from the rope-in end to the rope-out end increases gradually, reduces highly gradually, one side is provided with and boss bonded assembly grooving along the edge of inner end surface in the rope-out end, and the degree of depth, the width of grooving from the rope-in end to the rope-out end increases gradually.
Beneficial effect:
Groove of the present utility model and boss design when making steel rope be wrapped on the reel, are convenient to the steel rope change of direction, avoid steel rope in change of direction, to form violent shearing with drum wall, from but wire cable rupture increases service life of steel rope, improved the safety performance of gig.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of boss of the present utility model;
Fig. 3 is the structural representation of groove of the present utility model;
Mark is among the figure: 1, grooving, 2, inner end surface, 3, outer face, 4, the rope-in end, 5, the rope-out end, 6, boss.
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3: a kind of transition block that is used for cylindrical drum hoist, be circular arc at transition block inner end surface 2 and outer face 3, the thickness of transition block is 45 increases gradually to the rope-out end from the rope-in end, edge at the middle part of transition block one side along inner end surface 2 is provided with boss 6, boss 6 from the rope-in end 4 to the rope-out end 5 thickness increases gradually, reduces highly gradually, 5 one sides are provided with and boss 6 bonded assembly groovings 1 along the edge of inner end surface 2 in the rope-out end, grooving 1 from the rope-in end 4 to the rope-out end 5 the degree of depth, width increase gradually.
In the process of using, 4 directions by rope-out end 5 are installed on the reel from the rope-in end with transition block, during work, steel rope is wound to the transition block place of opposite side by a side of reel, when the resistance that is subjected to transition block boss 6, enter by rope-in end 4 in the grooving 1 of transition block, thus the direction of change steel rope.
