Description

The invention relates to devices for servicing containers, cargo barrels and containers that do not have special additional devices for slinging.

A device [1] is known, containing a traverse and slings attached to it with brackets (with grips) fixed to it. Such a device is used for lifting and carrying sheet material.

A device [2] is known, comprising a traverse and slings with hooks fixed to it. The specified device is used for lifting rolled products: pipes, rods, channels, etc. In addition, with the help of an additional axis, this device is used to lift and carry products with a through hole.

A device [3] is known, containing a traverse in the form of a frame and slings with hooks fixed to it. This device is used for transshipment of forest packs arriving in slings.

A device [4] is known, containing a traverse in the form of a frame and slings with hooks suspended from it. Such a device is designed to handle containers.

The above devices are used to lift and carry various products that have special devices for slinging: ears, staples, earrings, hooks, trunnions, eye bolts, etc. Hoisting operations with products that do not have the indicated devices present a certain complexity, especially when working with thin-walled cylindrical products of large dimensions.

To eliminate these shortcomings, the task was to create a hoisting-and-transport device for servicing products that do not have a special device for slinging, by creating a design that ensures reliable operation.

The inventive lifting and transport device, as well as the known one, includes a traverse in the form of a frame with earrings and slings.

According to the invention, the device is additionally equipped with a pallet similar in geometry to the traverse connected with the traverse with the traverse, at least three lines, while the ends of the lines are fixed to the traverse and the pallet with the fingers having an annular groove in the middle part, in addition, a sling tension device is installed on the traverse, and earrings are fixed on the pallet, equal in number to the traverse earrings, in addition, the traverse and the pallet contain stops directed towards one another.

These distinctive features are necessary and sufficient to achieve a technical result, namely:

- the device is additionally equipped with a pallet. Thus, the product receives a lower support;

- a pallet, similar in geometry to the traverse. This allows you to perform work with products or equipment of any shape: round, square, rectangular, indefinite shape, elliptical, etc .;

- the pallet is connected by at least three slings to the traverse, which ensures the retention of the product due to friction and pressure between the traverse and the product, and the product and the pallet;

- the ends of the slings are fixed on the traverse and the pallet with the help of fingers having an annular groove in the middle part. The presence of a finger with a groove when pulling the slings creates a fixation of this finger. The finger does not fall out of the openings of the ears, since for this it is necessary to overcome the tension of the lines;

- a screw device is installed on the traverse. This allows you to evenly distribute the load on the slings and clamp the product;

- earrings are fixed on the pallet, in an amount equal to the traverse earrings. This solution allows you to transfer the product both in vertical and horizontal position;

- the cross-arm and the pallet contain stops directed towards one another. The presence of stops allows you to work with a big guarantee of safety, both in the initial period after installing the product on a pallet, and in subsequent ones.

These distinctive features of the inventive transport device consist in a causal relationship and affect the achievement of a technical result.

The inventive transport device is illustrated by drawings.

Figure 1 shows a General view of the transport device.

Fig. 2 - section AA.

Figure 3 shows the finger-retainer.

The inventive transport device includes a traverse 1 in the form of a frame connected with a pallet 2, at least three flexible slings 3, with loops 4, while the top view of the pallet is similar in geometry to the traverse 1. Loops 4 slings 3 are fixed in the ears 5 of the traverse 1 and the pallet 2 with the fingers 6, having in the middle part an annular groove 7, in addition, a screw device 8 for tensioning the slings 3 is installed on the traverse 1. The traverse 1 and the pallet 2 contain stops 9 directed towards one another. For lifting and moving the device with a crane (not shown in FIG.), Earrings 10 are fixed in equal number on the crossarm 1 and on the pallet 2.

The transport device works like this.

On the product, for example, a cylindrical shape mounted on a pallet 2 between the stops 9, lower the beam 1 with the stops 8 and set so that the product is between its stops 8. After which the loops 4 of the sling 3 are inserted between the ears 5 of the beam 1 and the pallet 2 and the fingers 6 are inserted into their holes. Next, with the screw devices 8, the slings 3 are pulled. The slings 3, falling into the annular grooves 7 of the fingers 6, fix them. Thus, self-dropping of the fingers is excluded 6. In addition, by tensioning the slings 3, the product is clamped by the pallet 2 and the traverse 1. After performing these steps, the device with the product is lifted by a crane, hooking the crane with hooks on the earrings 10 of the traverse 1. Thus, the product moves in a vertical position. To move the product in a horizontal position, the device to the crane is hooked to the earrings 10, mounted on the traverse 1 and the pallet 2. To improve the reliability of operation and safety, the product is fixed with stops 9 mounted on the traverse 1 and the pallet 2.

This technical solution carries out the task and can be used to carry out lifting and transportation operations related to the movement of products of different geometric shapes that do not have sling devices.

The hoisting-and-transport device is simple in design and does not require special equipment and tools for manufacturing, convenient and reliable in operation.
