Described unidirectional porcelain wheel, the middle part of compression porcelain wheel are the thick dumb-bell shape in middle thin two, and cable is loaded to waist, avoid cable to skid off, good positioning effect.
Described unidirectional porcelain wheel one section of thinner edge of mid diameter is circumferentially with the friction layer that strengthens friction, and friction layer is comprised of some semicircle small embossments, by friction layer, increases the static friction force between cable and unidirectional porcelain wheel, plays better carrying effect.
Described frame plate is that a side is provided with the three-back-shaped of opening, and breach spacing is greater than cable diameter, and cable can be entered smoothly.
Described both sides, hoop upper end are provided with the two auxiliary plates that are connected with frame plate, by auxiliary plate, make frame plate and beam surface upper keep vertical, make cable vertical.
Frame plate is fixed on the crossbeam of standard knot by two hoops, cable is packed into unidirectional porcelain wheel and compressed the middle thin segment of porcelain wheel by frame plate indentation, there, under initial tension of spring effect, cable is compressed, when cable makes progress, unidirectional porcelain wheel is along rotating counterclockwise, ratchet is inoperative, cable can freely rise, when cable is static, ratchet acts on the end face of hook tooth, limit unidirectional porcelain wheel along clockwise rotating, between cable and unidirectional porcelain wheel, by friction of rolling, be converted to static friction force, simultaneously under the effect of friction layer, static friction force increases greatly, cable is played to good support effect.
Compared with prior art, the beneficial effect the utlity model has is:
This tower crane wire fixing device is taken turns with compressing porcelain by unidirectional porcelain wheel is set, and vertical cable is played to good support and position-limiting action, makes cable freely increase with tower machine simultaneously; Extend cable service life, by unidirectional porcelain wheel and the insulating effect that compresses porcelain wheel, improve safety factor; By friction layer is set, strengthen the static friction force of unidirectional porcelain wheel and cable, improve support effect.
