Description
Technical field
The utility model relates to a kind of gantry crane cable reel device, specifically is a kind of device that utilizes the machine power taking up and laying cable conductors.
Background technology
Straddle truck is a locomotive crane, and track-movable has bigger lifting capacity, is widely used in fields such as harbour, railway, highway, building.In straddle truck when work, is connected with electric supply installation by cable, and because of straddle truck needs often lifting transition, the very long one section cable of necessary outfit is in use with the mobile taking up and laying cable conductors of straddle truck.At present, the straddle truck that adopts the cable power supply is when newly purchasing, utilize the electric coil winder taking up and laying cable conductors, but it is in use synchronous because of existing objective friction to make that the cable folding and unfolding is difficult to the straddle truck walking, cause cable to be torn and cause outage, lifting object falls and causes security incident, and product produces quality problems because of not forming finished product continuously simultaneously.In addition, because straddle truck carries the fragile and big potential safety hazard of existence of electric coil winder, artificial taking up and laying cable conductors has been selected by a lot of units in charge of construction.Though artificial taking up and laying cable conductors can guarantee largely that cable is not damaged, reduces power breakdown, but still has some problems: the one, arrange the special messenger to be responsible for the cable folding and unfolding, increased construction cost; The 2nd, the workman is near the straddle truck operation, and personal security faces very big danger.
The utility model content
At above-mentioned technical problem, the utility model provides a kind of device that utilizes machine power folding and unfolding gantry crane cable, efficiently solves cable and damages problem frequent, that the construction safety coefficient is low, product quality can not get guaranteeing and management cost is high.
The technical scheme that the utility model adopted is as follows: a kind of gantry crane cable reel device, comprise the rotating disk that is used to coil cable, also comprise being used to realize the conversion of weight action potential, pack up the kinetic energy-potential energy converting and energy device of cable and be used to realize rotating disk power and the transmission device of weight power transmission thereby drive dial rotation; Wherein, described kinetic energy-potential energy converting and energy device and transmission device flexibly connect, and transmission device and rotating disk are in transmission connection.
Further, described kinetic energy-potential energy converting and energy device comprises and is welded on the slideway that straddle truck props up inboard leg, and the slideway two ends are provided with two pulleys, and a weight is slidingly connected on the slideway.Straddle truck is during toward operation at a distance, cable is stretched, drive dial rotation, by transmission device weight is risen to eminence, this moment, kinetic energy was converted into the potential energy of weight, when treating that straddle truck returns, weight descends because of deadweight, and potential energy is converted into kinetic energy, tense wire rope automatically, make steel wire rope drive transmission device and rotate, rotating disk rotates simultaneously rolls cable.By the conversion proportion of linear velocity and angular speed in the transmission process is set, can guarantee weight on slideway when mobile, straddle truck can normal operation in hundreds of meters scopes.
Further, described transmission device comprises that the axostylus axostyle connector that is installed on the grade beam reaches and the large toothed disk of axostylus axostyle one end pin joint, and described axostylus axostyle center fixed is socketed with an iron pipe, and described large toothed disk is connected with the denticle dish by chain, and little chain wheel is connected with rotating disk is coaxial again; Described axostylus axostyle connector by two built-in bearings watt close and be positioned at watt close in the middle of and the axostylus axostyle that passes bearing forms, fixedlys connected with an iron pipe in the axostylus axostyle centre, described iron pipe is connected with weight by the steel wire rope of walking around two pulleys.When cable drives dial rotation, driving the denticle dish earlier rotates, because of disk diameter coils diameter much larger than denticle, so that little chain wheel only turned over very little angle when cable was passed by a very long segment distance, large toothed disk and denticle dish chain are in transmission connection, and linear velocity is identical, again because the large toothed disk diameter coils diameter greater than denticle, the angle that large toothed disk turns over is littler, moves very little distance thereby drive weight.By the gearratio of transmission device is set, can guarantee that weight moves among a small circle, and straddle truck can normal operation in hundreds of meters scopes.
Further, described slideway comprises at least two slide rails, and described weight bottom is provided with at least two wheels that match with slideway, and weight can move up and down along slide rail.For reducing the friction of device, can in the subsidiary wheel of pulley and weight, bearing be set, reduced wearing and tearing to steel wire rope.
Further, described slideway top is provided with the one stroke switch, and the bottom is provided with a buting iron, and travel switch and buting iron are between two pulleys.Buting iron is established in the bottom can prevent that weight from exceeding the stroke lower limit when gliding and causing cable to be torn.Establish travel switch on slideway top, make straddle truck desire to exceed on the stroke and prescribe a time limit, weight is behind the touching travel switch, and straddle truck stops operation and do not drawn bad with the protection cable.
In the said apparatus, also comprise being arranged on the straddle truck rail and the transposer that is connected with port of export cable.Connect earlier transposer when cable is drawn, adjust the direction of cable, make that straddle truck can be in the flexible operation in two ends, the transposer left and right sides, and cable can not twine and damage by transposer.
The utlity model has following advantage:
1, utilizes the machine driving taking up and laying cable conductors, saved costs such as manpower, electric power, guaranteed personnel's safety.
2, this device has effectively reduced the impaired probability of cable, has improved construction safety coefficient and product quality.
3, this device construction is simple, principle is understandable, the convenience, with low cost of drawing materials, and has advantages of high practicability.
