Description

The utility model relates to technological processes and concerns devices for ensuring work with an extended flexible element, mainly for unwinding wires from cable coils when performing electrical work in the process of laying power and low-current networks. It can also be used for the formation and storage of such coils from various extended flexible functional elements: wires, cables, ropes, ropes, chains, hoses, cords, threads, etc.

Known device [1, Patent RU 195627 U1, IPC B65N 75/34] for working with an extended flexible element - a cable for winding - unwinding when equipping mobile fast-built fences. Such a device for performing the "unwinding" function contains a cylindrical axis mounted on a cruciform support with legs, on which a rim with a cylindrical pipe mounted on the crossbeams of the rim and enclosing the cylindrical axis of the cruciform support is mounted for rotation. Moreover, parallel to the cylindrical axis, there are installed: on the crossbeams of the rim - removable and non-removable spokes, and at one of the ends of the cruciform support - a U-shaped wire guide, made with the possibility of passing the unwound cable inside it.

To perform the "winding" function, this device is additionally equipped with a disc with a handle, fixed on top of the spokes.

However, the disadvantage of the device-analogue [1] is the complexity of its design.

It is known, taken as a prototype of a utility model, a simpler device for working with an extended flexible element - a wire unwound from cable coils [2, https://yandex.by/video/preview/?filmld=14489584648142909459&text=Reeling + wires + from + bays & noreask = 1 & path = wizard & parent-reqid = 1583898253661532-509221591570279194100371-sas3-6063 & redircnt = 1583899910.1].

Such a device contains a thrust bearing located freely on the support frame made of the lower and upper halves, which is the well-known "health disk" [3, http://damenwelt.ru/beauty/fitness/disk-zdorovya-i-uprazhneniya- dlya-poxudeniya.html], on the upper half of which a cylindrical branch pipe is installed, on which a cylindrical pipe is mounted.

Although the prototype device [2] is simpler than the analogue device [1], it also has a complicated design, which causes some inconvenience in using the product.

So, the presence of a support frame not only complicates the overall design of the device, but also increases its dimensions, thus complicating the movement of the device during operation.

The presence of two parts - a cylindrical pipe and a cylindrical pipe mounted on it, also complicates the design of the device and requires additional time for their assembly.

Also, some inconvenience for carrying the product, for example, by the hand of an electrician, is caused by the lack of a handle.

The cylindrical shape of the pipe does not allow direct putting on and unwinding of coils with different internal diameters. This requires the use of a complex mechanical device for adjusting the said pipe to specific diameters of cable coils.

In addition, the presence of a flat element - "Health disc" and a cylindrical pipe installed on it increases the likelihood of entanglement when unwinding an extended flexible element from coils with a diameter equal to or greater than the disc diameter.

These disadvantages also worsen the performance during the operation of the product, and in the aggregate - reduce the efficiency of its use.

Therefore, the task of the utility model is to simplify the design and increase the efficiency of the device for working with an extended flexible element.

The problem is solved by the fact that (Fig. 1-5) e device for working with an extended flexible element containing a bearing (1) made of the lower and upper halves (2, 3), on the upper half (3) of which there is a pipe (5) , has distinctive features: the pipe is made conical and rigidly mounted on the upper half of the bearing (1) through the bowl.

The execution of a tapered pipe is aimed at making it possible to put on and unwind coils of extended flexible elements with different inner diameters of these coils, and does not require a complex mechanical device to adjust the pipe to the diameters of the coils. This improves both the efficiency of these operations and increases the usability of the product.

Rigid fastening to each other through the bowl of the upper half of the bearing and the pipe is aimed at simplifying the overall design of the product, since there is no need to use additional relatively large elements of the branch pipe and support frame - as in the prototype device [2]. In addition, it does not require additional time-consuming assembly of such a product.

The use of the bowl allows you to unwind / unwind any extended flexible functional elements of various diameters with the formation of coils without the risk of overturning the device and without the risk of entanglement of the unwinding / unwinding object in the structural elements of the device. This improves the efficiency of such operations.

In general, the listed advantages make it possible not only to simplify the design, but also to increase the efficiency of using the device for working with an extended flexible element.

Additional distinctive features of the utility model aimed at enhancing the mentioned effects:

- the bowl (4) has an outer diameter greater than the outer diameter of the bearing (1);

- the lower half (2) of the bearing (1) is equipped at the edges with point support anti-slip elements (9),

- in the pipe (5), along it, through holes (10) are made with the possibility of insertion into the upper ones and passing through them of a removable rod (11), at the end of which a through hole (12) is also made, and into the through holes located below (10) - with the possibility of inserting into them and passing through them the end of an extended flexible element (15).

- a handle (16) is attached to the upper end of the pipe;

- at the bottom of the lower half (2) of the bearing (1), a wire element (17) is fixed, bent to form a protrusion (18), behind the bowl and to form a U-shaped guide window made with the possibility of passing an extended flexible element (15) through it.

The essence of the utility model is illustrated by illustrations, where Fig. 1 shows a general view of the initial configuration of the device for working with an extended flexible element; in fig. 2 is a bottom view of FIG. 1; in fig. 3 - in the same way as in FIG. 1, but with additional equipment for the convenience of using such a product; in fig. 4 is a bottom view of FIG. 3; in fig. 5 shows a photo of the manufactured product according to FIG. 1 using a rod and a screwdriver to wind an extended flexible element.

The device (Fig. 1, 2) for working with an extended flexible element is formed on a bearing, for example, on a thrust plain bearing, or a ball thrust bearing, or on a roller thrust bearing, or on a bearing called "health disc" [3].

Such bearings consist of a lower half (2) and an upper half (3), on which a pipe (5) is rigidly installed through a bowl (4). Between the lower half (2) and the upper half (3), along their perimeter, are located (not shown), for example, rolling bodies (balls or rollers), or sliding bodies (for example, friction liners).

The lower supporting part (6) of the pipe (5) is fixed rigidly to the bottom (8) of the bowl (4), for example by rivets (7). This bottom (8) is mounted on the upper half (3) of the bearing (7).

The bowl (4) is made with an outer diameter greater than the outer diameter of the bearing (7), the lower half (2) of which is equipped along the edges with point support anti-slip elements (9) (Figs. 1 and 2).

In the pipe (5, Fig. 1, 3), along it, through holes 10 are made with the possibility of inserting into the upper ones and passing through them, for example, a removable rod (11, Fig. 3), and into the lower ones - with the possibility inserting into them and passing through them the end of the extended flexible element.

At the end of the removable rod (11), a through hole (12) is also made for inserting another rod (not shown) into it, or (Fig. 5) a screwdriver (13), performing the function of a handle by acting on it with a hand (14) to rotate the pipe (5) in the case of winding an elongated flexible element (15) on it in order to form a coil from it (not shown).

For the convenience of carrying the product (Fig. 3, 5), a handle (16) is attached to the upper end of the pipe (5).

At the bottom (Fig. 2, 4) of the lower half (2) of the bearing (7), a wire element (17) is fixed, bent to form a protrusion (18) behind the bowl (4) and to form a U-shaped guide window (79) with the possibility of providing passing through it (Fig. 5) an extended flexible element (15) when unwinding from the coil (not shown).

Thus, the wire element (17) acts as a guide, for example for a cable, in order to simplify unwinding from the coil, ensuring its exit at one point of such a product.

Installed (Fig. 4) wire element (17) from below on the lower half (2), for example, using clamping bars (20) fixed with rivets (21) or screws.

Such a product is used as follows.

When twisting (Fig. 5) an extended flexible element (15), for example, a cable, wire, corrugated pipe, etc., its end is threaded into the selected holes (10) of the pipe (5). By further action, for example, with a screwdriver (13), the pipe (5) with the bowl (4) is rotated and the extended flexible element (15) is wound to form a coil from it (not shown).

In order to accurately orient the winding of the elongated flexible element (15) onto the pipe (5) with the placement of the formed coil inside the bowl (4), the elongated flexible element (15) is preliminarily passed through the U-shaped guide window (19).

When untwisting from the formed coil, an extended flexible element (15) is pulled by its free end (not shown), passing it through the U-shaped guide window (19), rotating the coil with a pipe (5) and a bowl (4) on a bearing (7) ...

If it is necessary to place on such a device another ready-made coil, for example, taken from a warehouse, or even several, then these coils (not shown) with their inner holes are placed on the pipe (5). Moreover, according to a tight fit in the zones corresponding to the diameter of the lower edge of the inner hole of each bay, with a possible location, both inside the bowl (4) and above it.

In this form, the formed product can be compactly stored, carried or transported.
