Description

The utility model refers to equipment and is designed for lifting, moving and transporting packages with large glass, for example, with DLF glass (3210 × 2250 mm), jumbo format (6000 × 3210 mm) in glass factories and glass processing plants ...

A device for lifting a glass stack (tooling) is known from the prior art, which consists of two pairs of corner elements intended for installation on four corners of a glass stack (patent US5678691, publ. 21.10.1997). On the perpendicular sides of each of the corner elements there are brackets for fixing the tapes in them. The tapes are intended for strapping a glass package vertically and horizontally at the same time. On two corner elements intended for installation on the upper corners of a vertically installed glass package, there are slinging nodes (nodes for fixing slings in them). Moreover, the slinging units are located on the lateral sides of the corners, i.e. on the sides adjacent to the vertical side of the glass pack. A significant disadvantage of this equipment is that the slinging units are located on the sides of a vertically installed glass stack, since when a large glass stack is lifted vertically with a sling, the glasses are bent into an arc, which can lead to their damage. Therefore, this rig design cannot be used to lift large glass panes. In addition, since the slinging unit is located on the sides of the glass package, for fixing the corner elements on the glasses and the possibility of lifting the glasses with the rigging, both horizontal and vertical fixing of the corner elements with straps is necessary, which complicates the design of the rigging itself. Another disadvantage of the tooling is the laboriousness of its installation, due to the need for horizontal and vertical strapping of the glass pack with four pairs of strips. Particularly laborious is the horizontal strapping of large-sized glasses, while it is necessary to pass the bands under the pyramid when strapping, on which glasses are usually installed.

Also known is a tooling for vertical lifting of glasses, consisting of four corner elements for fixing them on the corners of a glass stack (patent CN201254355, publication date 06/10/2009). A slinging unit is made on two corner elements. The specified corner pieces are designed to be installed on the upper corners of the glass stack so that the side of the corner with the slinging unit is adjacent to the upper horizontal end side of the glass stack. On the sides of the corner elements, there are recesses for the location of the tape for horizontal and vertical strapping of the glass package. There are no recesses on the sides of the corner elements where the slinging unit is located, since each slinging unit, consisting of a pair of lugs, is designed to accommodate the tape between the lugs. The disadvantage of the design of this equipment also lies in the fact that lifting the glass pack is possible only with the simultaneous horizontal and vertical strapping of the glass pack with ribbons, which leads to laboriousness during the installation of the device (especially with horizontal strapping). When the glasses are lifted with the exception of the horizontal strapping, the upper corner elements are inverted and they are torn off the glass stack, as a result of which the device cannot hold the glass stack, which does not allow the known rigging to be considered reliable when lifting the glasses.

The technical problem to be solved by the claimed utility model consists in the development of a reliable and simple design of equipment for lifting glass sheets, with the exclusion of the risk of damage to large glass.

The technical result of the utility model is to improve the performance of the tooling by increasing the reliability of the tooling, reducing the labor intensity during installation, simplifying the design, and improving the quality of glass transportation.

The specified technical result is achieved in a device (equipment) for lifting glasses, consisting of a pair of corner elements connected by two parallel metal strips, a slinging unit is made on one of the corner elements, while the slinging unit is located between the metal strips, and the side of the corner element with a slinging unit contains two sides; corner elements are made with the possibility of installation on oppositely located upper and lower corners of the glass stack with its vertical strapping with metal strips and placement on the upper corner of the glass stack of the corner element with a slinging assembly; moreover, the upper corner element is configured to be installed on the glass stack so that the side of the corner element with the slinging unit adjoins the upper horizontal side of the glass stack.

For lifting onto a stack of glasses, two devices described above are installed in parallel.

The tapes can be made of metal or durable polymer material.

The slinging unit may contain one double eyelet and is intended for fastening the sling in it, by placing the sling loop between the paired elements of the double eyelet with the further passing the metal pin through the holes in the double eyelet to firmly fix the sling loop in the slinging unit.

Two tapes allow fixing the sides of the corner pieces adjacent to the upper and lower horizontal end sides of the glass stack along the edges. This eliminates the inversion of the corner elements (including due to the location of the slinging unit between the straps) when lifting the glass pack with a sling, which increases the reliability of the device (equipment) for lifting the glasses and protects the glass pack from damage during lifting, and, therefore, leads to improving the performance of the device.

The location of each tape from the pair between the edge of the corner element and the slinging unit allows fixing the location of each of the bands at the edges of the horizontally located sides of the corner elements and excluding the slipping of the tapes from the nodal elements during operation, which can lead to the glass stack falling out during lifting. Thus, the specified design of the device makes it possible to increase the reliability of the operation of the device being patented and leads to an increase in the operational characteristics of the device.

One of the corner elements with a slinging unit is made with the possibility of placing the corner element on the upper corner of the glass stack (when it is installed vertically) so that the side of the corner element with the slinging unit adjoins the upper horizontal side of the stack. Thus, the location of the slinging unit on the upper horizontal end of the glass package allows the glass to be lifted with slings with the exclusion of glass bending and damage, which, as a result, improves the quality of transportation of goods and the operational characteristics of the device.

The claimed utility model is illustrated by Figures 1-3.

FIG. 1 is a general view of two glass lifting devices mounted on a vertically mounted glass sheet.

FIG. 2 is a general view of a corner piece for installation on the upper corner of a glass stack (upper corner piece).

FIG. 3 is a general view of a corner piece for installation on the lower corner of a glass stack (bottom corner piece).

FIG. positions 1-11 show:

1 - corner piece for installation on the upper corner of a glass package (upper corner piece),

2 - corner piece for installation on the lower corner of a glass package (bottom corner piece),

3 - metal tape,

4 - slinging knot,

5 - glass,

6 - upper horizontal glass end,

7 - horizontal side of the upper corner element,

8 - side,

9 - lower horizontal glass end,

10 - paired elements of a double eyelet,

11 - fixing pin.

A device (equipment) for lifting large glass, for example, DLF glass (3210x2550mm, 3210x2250mm) consists of an upper corner piece 1 and a bottom corner piece 2, connected by a pair of metal bands 3. The corner pieces are designed to cover the opposite upper and the bottom corners of the vertically mounted glass. The upper corner piece has a horizontal side 7 for fixing the upper horizontal end surface of the glass corner. In the middle of the horizontal side 7, a slinging unit 4 is made, consisting of a double eyelet, including paired elements 10, which have coaxial holes for passing a steel pin 11 through them. On the edges of the horizontal side 7, there are sides 8.

Each metal band 3 runs between the flange 8 and the slinging unit 4. Thus, the slinging unit 4 is formed between the two belts.

Installation of the patented device is carried out as follows.

DLF glass is vertically mounted on a pyramid. The upper and lower corner elements 1, 2 of one device for lifting glass are installed on the opposite upper and lower corners of the glass 5. When installing the corner elements, the glass is vertically strapped with two metal strips 3. Then the operator goes to the second end vertical side of the glass and in the same way installs the second device for lifting glass. As a result, the corner pieces are firmly fixed to the four corners of the glass. The corner pieces together with the straps form a secure attachment for lifting and transporting the glass bag.

To lift the glass between the paired elements 10 of the double lugs of each slinging unit 4, a sling loop is placed. Further, to fix the loops of the sling in the slinging units 4, 1 steel fixing pin 11 is passed through the coaxial holes in the double lugs of each unit 4.

Then, after fixing the slings in the rigging, the glass is lifted vertically and moved to shipment, warehouse or to some other device for processing.

The developed device is characterized by a carrying capacity of up to 2.5 tons.

Installation of the patented device for lifting glass is quite simple and not laborious. The design of the upper corner element of the device with bumpers along the edges and a slinging unit in the middle of the horizontal side allows two mounting tapes to firmly fix both edges of the horizontal side of the corner element on the upper horizontal end of the glass. As a result, the reliability of fixation of the upper corner element on the corner of the glass is achieved and the inversion and breakdown of the upper knot element is excluded when the glasses are lifted by the slinging unit with only one vertical strapping. Thus, there is no need for additional horizontal glass strapping (which is much more laborious than vertical) for reliable glass retention. The absence of the need for horizontal strapping when using the patented device leads to a simplification of its design and installation. At the same time, when using the device, the integrity of the glasses is preserved during lifting, since the vertical strapping, in contrast to the horizontal, does not lead to bending of a large glass package during transportation, which leads to an increase in the quality of transportation and operational characteristics of the device.
