Embodiment
Contrast accompanying drawing below, by description to embodiment, to effect and operation principle, the manufacturing process of the mutual alignment between the shape of the specific embodiment of the present invention such as related each member, structure, the each several part and annexation, each several part and manipulate method etc., be described in further detail, inventive concept of the present invention, technical scheme had more complete, accurate and deep understanding to help those skilled in the art.
The of the present invention structure expressed as Fig. 1 to Fig. 4, the present invention is a kind of large cable laying device, comprises draw drum 2.Cable winding is on draw drum 2.
One, in order to solve the problem that exists at the described present known technology of this specification background technology part and to overcome its defective, realization is to the improvement of cable laying construction technology, improve cable laying speed, improve laying quality, break away from constraint that crane cooperates cabling, guarantee the workmen safely, the goal of the invention that reduces cost, the key of the concrete technical scheme of employing is:
Large cable laying device provided by the present invention, described large cable laying device is established pay off rack 1, roller bearing 5 is established at the center of described draw drum 2, the dead in line of described roller bearing 5 and draw drum 2, and the two ends of described roller bearing 5 are stretched out and are bearing on the vertical draw-in groove of described pay off rack 1 from the both ends of the surface of described draw drum 2.
Described roller bearing 5 is bearing on the pay off rack 1, and roller bearing 5 contacts with the draw-in groove of pay off rack 1 both sides, and roller bearing 5 can rotate in the pay off rack draw-in groove.
Draw drum 2 rises to certain altitude at pay off rack 1 with roller bearing 5, and behind the draw drum 2 built on stilts certain altitudes, draw drum 2 can 360 ° of rotations on roller bearing 5.
Because adopted pay off rack 1 supporting, fixing draw drum 2, draw drum 2 can be unsettled, makes things convenient for it to rotate freely, and carries out unwrapping wire, effectively resistance is laid in minimizing.
Two, pay off rack is for being symmetrical arranged:
Above-described pay off rack 1 is two of symmetry, is located at respectively outside the both ends of the surface of described draw drum 2.Described pay off rack 1 is used for fixing draw drum 2.
Because the two ends of roller bearing 5 all need supporting, like this could be steady, thus adopt two pay off racks 1 that are symmetrically distributed, and the installation of draw drum 2 also is convenient in 1 two distributions of pay off rack.
Roller bearing 5 relies on the jack vertical lifting to rise with draw-in groove, make draw drum 2 break away from ground, cable is easy to draw from draw drum 2 and delivers to the job location like this. by the structure of pay off rack, do not need crane to cooperate, manually can independently construct, process is convenient to control, and reaches the effect that reduces the mechanical stage student contributions pooled to pay for class activities.
Three, the climbing structure of draw drum 2:
Establish jack 6 on the pay off rack 1 of the present invention, the piston rod supporting of the two ends of described roller bearing 5 by described jack 6, and the piston rod of described jack 6 stretch out direction for up with the direction of described roller bearing 5 jack-up.
Described roller bearing 5 relies on jack 6 vertical lifting to rise with draw-in groove, makes draw drum 2 break away from ground.
Four, setting reeler structure:
As shown in Figure 3 and Figure 4, large cable laying device of the present invention is established setting reeler 3, and described setting reeler 3 is fixed on the cable testing bridge 8 by rolling stand 7, and cable slides on the outer round surface of described setting reeler 3.
Cable lays on cable testing bridge 8 by setting reeler 3.Setting reeler 3 is used for the rolling friction replacement cable of cable and cylinder and the sliding friction of crane span structure, effectively reduces and lays resistance.Setting reeler 3 relies on rolling stand 7 to be fixed on the cable testing bridge 8, and cable travels forward on setting reeler 3, replaces the sliding friction of prior cable and crane span structure with the rolling friction of cable and cylinder 3.
With the rolling friction replacement cable of cable and cylinder and the sliding friction of crane span structure, reduce and lay resistance, guarantee laying quality.Each cylinder can reach the effect that replaces a people.185 cables with one 200 meters long are example, just can construct about 20 people, reach the damage of avoiding cable insulation, the effect that reduces labour cost and raising job safety hidden danger.
Five, fourfold block structure:
As shown in Figure 2, the turning of cable testing bridge 8 of the present invention, if fourfold block 4, the periphery of the four rolling of described fourfold block 4 is the curved surface of mid diameter less than the two ends diameter, described four rolling parallel axes distributes, the outer round surface of described roller constitutes cable passage, and described cable passes from cable passage.
Above-described fourfold block 4 is positioned at cable testing bridge 8 turnings, and the cable turning changes direction by fourfold block 4.So fourfold block 4 changes cable and is laying direction of travel, plays the effect that cable is turned flexibly and protected the cable insulation skin.
Six, cable pulling nets structure:
Large cable laying device of the present invention is established the cable pulling net, and described cable pulling net and described cable ends are fixed.
Cable links with hoisting rope by the cable pulling net; The cable pulling net is enclosed within cable end, trailing cable.The cable pulling net is connected with elevator.
Described cable pulling net is enclosed within cable end, and hoisting rope is connected with the traction net more then, is convenient to the elevator trailing cable like this.
Seven, the actuating unit of cable pulling:
Large cable laying device of the present invention is established hoist engine, and the steel wire rope head of described hoist engine is connected with described cable pulling net.
The hoist engine steel wire rope head is connected with the cable pulling net, and cable laying tractive effort is provided.
Described employing elevator replaces the power of artificial cabling, and people's task difficulty reduces greatly thus, and the cabling personnel can be not overtired, and coefficient of safety improves greatly, and efficiency of construction also increases exponentially.It is good just passable that the workmen need only tens meter amperes arranges a personal monitoring.
Eight, the control system of large cable laying device:
Large cable laying device of the present invention is established frequency converter, and described frequency converter is used to control the motor of hoist engine.
Frequency converter is used to control the elevator motor, with frequency converter elevator is carried out the speed of travel that speed governing reaches effective control cable.
The utilization of described frequency converter, mainly be to consider the core of large cable laying device is how to control the speed of elevator, directly say to be exactly the speed of travel of control cable on crane span structure, because cable is very big very heavy, if speed can not effectively be controlled, just in case cable blocks in the crane span structure somewhere, must cause the generation of accident.With frequency converter timing in range of motor speeds any one speed we can both be transferred to; and frequency converter self-protection function is very strong; sensitivity is also very high; the excessive frequency converter of line current outage automatically when running into the stuck phenomenon motor rotation blockage; and can accomplish to want to stop just stopping; think to think slowly just slowly, and also have the rotating function soon just soon.Therefore the problem of all solutions has just all solved.
In conjunction with the accompanying drawings the present invention has been carried out exemplary description above; obviously specific implementation of the present invention is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or design of the present invention and technical scheme are directly applied to other occasion without improving, all within protection scope of the present invention.
