Aluminum cald steel wire wire drawing machine unwrapping wire bus cable device
Technical field
What the utility model aluminum cald steel wire wire drawing machine unwrapping wire bus cable device related to is a mechanism of the supporting paying off system of a kind of aluminum cald steel wire wire drawing machine front end.
Background technology
The electrical energy production of China mainly is distributed in western part, and the power load center mainly concentrates on the coastal region in east China.Along with growing continuously and fast of Chinese national economy, demand to electric power is significantly soaring, increase wire cross-section area (having increased simultaneously diameter and weight) at old circuit and can increase transmission of electric energy, but need to transform steel tower with height and the intensity of raising tower head, even change steel tower.Although can increase the transmission capacity of circuit and utilize original line route (namely not increasing land used), but still need larger investment.Generally must after strict calculating, when being difficult to solve, just use additive method.
The appearance of aluminum cald steel wire wire, do not changing former transmission line of electricity path, also must transform the enhancing steel tower hardly, only need to change novel conductive wire, this novel conductive wire has identical or very close mechanical property with the employed wire of former circuit, behind the wire that more renews, circuit just can be carried more electric energy, reaches the purpose of circuit increase-volume.
Need all cross-sectional areas to equate because the aluminum cald steel wire aluminum steel is twisted into cable, the electric weight that passes through like this could be constant.This has just determined aluminum cald steel wire line any one link in production and use procedure, the circularity of the aluminum cald steel wire line that all can not be affected, smoothness.Therefore the aluminum cald steel wire line is when entering the aluminum cald steel wire wire drawing machine, must come even unwrapping wire according to the winding displacement rule of draw drum, the phenomenon that mutual squeeze and destroy aluminum cald steel wire line surface especially can not be arranged in the two ends of drum aluminum cald steel wire line commutation unwrapping wire, otherwise aluminum cald steel wire line skeining has larger added losses, will produce defective work like this, cause the waste of aluminum cald steel wire line, thereby increased the cost of product.The winding displacement of the unwrapping wire of conventional aluminum cald steel wire all is manual intervention adjustment commutation, in process of production, operating personnel will ceaselessly observe the winding displacement situation of aluminum cald steel wire line on draw drum, whether the two ends of seeing drum have the phenomenon of mutual extruding, discovery has this situation, and machinery is adjusted the position of the aluminum cald steel wire winding displacement commutation at drum two ends artificially.Wire-crossing wheel spare is the passive linear axis bearing part traveling priority that passes through under the drive of aluminum cald steel wire line, so just realizes the passive winding displacement of aluminum cald steel wire line.When aluminum cald steel wire line winding displacement generation catching phenomenon, can only adjust by operator's manual intervention.
Summary of the invention
The purpose of the utility model device is in aluminum cald steel wire unwrapping wire winding displacement production and application, often can use the aluminum cald steel wire drum of different size, and passive winding displacement easily produces the phenomenons such as clamping stagnation, so that the phenomenon that the aluminum cald steel wire line loss is hindered can appear in passive winding displacement; Because what winding displacement adopted is passive adjustment commutation, above-mentioned various error can cause the operative employee to want constantly winding displacement to be commutated to observe adjustment, so that operative employee's workload is large especially, at every moment to note equipment unwrapping wire winding displacement, can not leave machine, even the phenomenon of the bad clamping stagnation of unwrapping wire winding displacement still can occur like this; Provide a kind of aluminum cald steel wire line bus cable device to adopt automatic winding displacement apparatus, by this automatic winding displacement apparatus when the device start, at first select the dish of plate wide, before beginning, production process selects by the inductive switch to variable-frequency motor screw mandrel winding displacement, and parameter is inputed to electric control system, by electrical system the winding displacement of aluminum cald steel wire line is selected.
Aluminum cald steel wire wire drawing machine unwrapping wire bus cable device is to take following technical scheme to realize:
Aluminum cald steel wire wire drawing machine unwrapping wire bus cable device comprises support, holder, line slide rail, optoelectronic switch sensor, optoelectronic switch sensor stand, trapezoidal screw, winding displacement support plate base, wire-crossing wheel, travel switch, tyre coupling, deceleration variable-frequency motor, frequency converter and control cabinet.Wire-crossing wheel is fixed on the winding displacement support plate base, the winding displacement support plate base is installed on the trapezoidal screw by trapezoidal nut, by trapezoidal screw active winding displacement, trapezoidal screw connects by tyre coupling with the deceleration variable-frequency motor, two terminals (limit) position at screw mandrel is respectively equipped with travel switch, line slide rail is fixed on the sliding track holder, sliding track holder is rack-mount, two optoelectronic switch sensor stands are installed in respectively near on the support at trapezoidal screw two ends, the optoelectronic switch installation of sensors can be according to the position of the wide setting optoelectronic switch sensor of dish before using on the optoelectronic switch sensor stand.Frequency converter is installed on the control cabinet, and frequency converter links to each other with variable-frequency motor by control line.Described optoelectronic switch sensor links to each other with frequency converter by holding wire.
Described trapezoidal screw drives the winding displacement support plate base and moves back and forth, and moves back and forth the purpose that reaches winding displacement thereby the winding displacement support plate base drives again wire-crossing wheel mounted thereto.Variable-frequency motor revolution one volume can send signal to control cabinet by frequency converter, and the trapezoidal screw walking is about the displacement of aluminum cald steel wire linear diameter, so just realizes the winding displacement of aluminum cald steel wire line.When the reversal point of aluminum cald steel wire winding displacement to the dish two ends, detect realization by the optoelectronic switch sensor.
Operation principle: when aluminum cald steel wire wire drawing machine unwrapping wire bus cable device uses, when device start, at first select the dish of plate wide, before production process begins, select by the inductive switch to variable-frequency motor screw mandrel winding displacement, and parameter is inputed to electric control system, by electrical system the winding displacement of aluminum cald steel wire line is selected, the winding displacement pitch is controlled by the rotating speed of variable-frequency motor in addition, feed back to again frequency converter, finally send instruction by electric cabinet, revise the payingoff speed of paying out machine.
Realized full-automatic winding displacement fully by the unwrapping wire winding displacement that adopts this aluminum cald steel wire line automatic winding displacement apparatus aluminum cald steel wire line, the winding displacement quality is high, no matter adopt the drum of which kind of specification, manually do not adjust the needs operator, alleviated widely operative employee's labour intensity in the production process, reduce the disqualification rate of product, improved the quality of product.
