Abstract
The utility model relates to a pay-off support, in particular to a location self-adaptation pay-off support capable of braking automatically. The location self-adaptation pay-off support capable of braking automatically comprises a support. A rolling shaft of a pay-off disc is fixed at one end of the support. The rolling shaft is horizontally installed on the support through two bearings. The location self-adaptation pay-off support capable of braking automatically is characterized by being further provided with at least two sliding rails arranged in parallel and fixed on the ground. The bottom of the support is clamped on the sliding rails through sliding buckles. The sliding rails, the rolling shaft and a coil are in parallel in the axial direction. The other end of the rolling shaft is provided with a friction wheel. A friction ring used for hooping the friction wheel is arranged on the support. According to the technical scheme, the location self-adaptation pay-off support capable of braking automatically is adjustable in position and capable of preventing a varnished wire from influencing the position of a worker and avoiding excessive paying off.
Description
Technical field
The utility model relates to a kind of wire-unfolding rack, particularly the wire-unfolding rack that uses during a kind of transformer coil winding.
Background technology
The transformer capacity of using is more big now, and is also more big to the influence of electrical network, requires its fail safe also more and more higher.The workmanship performance of transformer not only requires electric property reliable, and mechanical stability, anti-short circuit capability also should be more reliable.Stability mainly shows and namely requires the high-voltage coil and low-voltage coil electromagnetic balance on the manufacture process control of coil, axially turn-to-turn closely, be evenly distributed.Therefore require the coil winding process, radially will roll tightly, axially closely arrange.The coil winding process is that the draw drum that will be wound with enamelled wire is installed on the pay off rack, and iron core is installed on the tensioning apparatus, and tensioning apparatus rotates to twine enamelled wire, the hand-held enamelled wire of workman adjust winding position with guarantee coil axes to turn-to-turn closely.
Though existing pay off rack can satisfy the demand of unwrapping wire to a certain extent, but it still exists certain problem, be in particular in: 1, because coil not only radially will roll tightly, axially more need tight arrangement, the workman not only will strain enamelled wire when twining enamelled wire, more need the continuous position that axially back and forth changes enamelled wire along coil.And the position of pay off rack is fixed, this causes the angle between enamelled wire and the coil constantly to change, the workman is clipped in the position of angle, its erect-position is a greater impact, and is not easy along coil axially-aligned enamelled wire, 2, because in the process of coiling, the workman need stop coiling often and adjust the enamelled wire position, and the draw drum on the pay off rack can continue unwrapping wire under action of inertia at this moment, and the winding that enamelled wire very easily takes place damages.
The utility model content
The technical problems to be solved in the utility model provides a kind of position and can adjust, and prevents that enamelled wire from influencing workman's erect-position, and can prevent the pay off rack of excessive unwrapping wire.
In order to solve the problems of the technologies described above, the utility model provides and includes support, one end is the roller bearing of draw drum fixedly, this roller bearing is rack-mount by two bearing levels, also be provided with at least two parallel and be fixed on the slide rail on ground, described frame bottom snaps fit onto on the slide rail by slide fastener, described slide rail and roller bearing, coil axially parallel, the other end of described roller bearing is provided with friction pulley, and described support is provided with a drag ring of waling friction pulley.
Adopt the self-stopping position self adaptation pay off rack of technique scheme to have following advantage: 1, since be provided with at least two parallel and be fixed on the slide rail on ground, frame bottom snaps fit onto on the slide rail by slide fastener, slide rail and roller bearing, the coil axially parallel, according to the shortest principle of vertical line between two parallel lines as can be known, support can move along parallel sliding track, so that enamelled wire as far as possible perpendicular to coil axially, this moment, angle no longer changed, the easier axially-aligned enamelled wire along coil of workman, and because the angle between enamelled wire and the coil no longer changes, workman's erect-position is also no longer influenced; 2, because because the other end of roller bearing is provided with friction pulley, support is provided with a drag ring of waling friction pulley, when the workman need stop coiling and adjust the enamelled wire position, friction pulley stops operating rapidly under the effect of drag ring, and organizes the inertia rotation of draw drum by roller bearing.
As preferred version, for the ease of adjusting the frictional force between friction pulley and the drag ring, thereby friction compensation is mixed bad, and an end of described drag ring is fixed on the support, the other end connects on the support by adjusting nut, changes the suffered resistance of friction pulley by the position that changes adjusting nut.
As preferred version, under the prerequisite that guarantees the slide rail effect, that tries one's best reduces cost, and guarantees that simultaneously slide rail does not bend under long-term stressed situation and is out of shape, and described slide rail has two, and its two ends are connected and fixed by two joint pins.
Description of drawings
Fig. 1 is the structural representation of the self-stopping position of the utility model embodiment self adaptation pay off rack.
Embodiment
Below in conjunction with drawings and Examples technical solutions of the utility model are further specified:
As shown in Figure 1, the utility model provides a kind of self-stopping position self adaptation pay off rack, include support 1, one end fixedly has the roller bearing 3 of draw drum 2, this roller bearing 3 is installed on the support 1 by two bearing 4 levels, also be provided with two parallel and be fixed on the slide rail 5 on ground, support 1 bottom snaps fit onto on the slide rail 5 by slide fastener, slide rail 5 and roller bearing 3 and coil axially parallel, the two ends of slide rail 5 are connected and fixed by two joint pins 7, the other end of roller bearing 3 is provided with friction pulley, support 1 is provided with a drag ring 9 of waling friction pulley, one end of drag ring 9 is fixed on the support 1, and the other end connects on the support 1 by adjusting nut, and the two ends of slide rail 5 grooves are connected and fixed by two joint pins 7.
Slide rail 5 preferred two according to the stressed size of slide rail 5, can suitably increase parallel slide rail number.
Above-described only is preferred implementation of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection range of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
