Description

TOOL HANDLING AND TIPPING FOR A TELESCOPIC TROLLEY

Technical area

The present invention relates to the field of barrel handling and spilling tools. The invention will find particular use in the field of crushing coal or cement, where it is appropriate to pour drums of balls or steel balls into ball mills.

State of the art

Coal is traditionally crushed using a ball mill consisting of a drum four meters in diameter and approximately fifteen meters long, into which approximately 70 tonnes of steel balls or balls are discharged. The rotation of the drum makes it possible to knead the coal and the balls and, thus, to crush the coal. The wear of the balls requires making steel balls in the drum, or even replacing them. A similar use exists for crushing cement.

The steel balls are packaged in drums whose dimensions correspond substantially to oil drums. The mass of a drum of steel balls is of the order of a ton.

Traditionally, the handling of such drums is carried out by means of slings; the barrel is transported in an extended position, more or less horizontally, by means of slings above the drum where it is only opened by an operator so that the balls pour into said drum.

To overcome in particular the need for operator intervention in order to open the barrel above the ball mill, a person skilled in the art has developed a hydraulic clamp equipped with a jaw configured to clamp the barrel in a vertical position. and a jaw rotation system configured to pivot on one or the other of its lateral sides of the barrel in order to pour the steel balls into said grinder.

This hydraulic clamp is mounted on a handling trolley, said clamp being connected to the hydraulic circuit of the trolley in order to be able to operate. Once the hydraulic clamp in position around the barrel arranged vertically, the latter is opened by the operator then it is moved by the handling trolley to the crusher where the rotation system is then actuated to pivot said barrel to the side, so as to pour the balls.

Such a hydraulic clamp is expensive. In addition, the connection of the hydraulic clamp requires intervention on the hydraulic circuit of the industrial truck. Furthermore, the handling of the handling trolley is not easy because it is advisable to pour the balls by rotating the barrel on the side. Summary of the invention

The present invention aims to overcome the aforementioned drawbacks of handling systems and spill of barrels according to the prior art. To this end, the invention relates to a barrel handling and dumping tool which is configured to be mounted on a telescopic cart and manipulated by means of said cart. Such a telescopic cart is also called a "manuscopic" cart.

Such a telescopic cart traditionally comprises a motorized vehicle provided with a telescopic arm at the end of which is fitted a device for hooking a tool of the fork type for handling pallets or a bucket.

The plaintiff had the ingenuity to develop a tool complementary to the already existing range of tools for telescopic trolley and specially adapted for the handling and dumping of drums.

According to the invention, the tool comprises a structure which preferably has a longitudinal axis and which is provided with a rear side and a front side. A hooking system is arranged on the rear side of the structure, this hooking system being configured to mount said tool on the hooking device of the telehandler. In addition, a barrel strapping system is arranged on the front side of the structure, said strapping system being configured to clamp the barrel on its revolution contour, the axis of revolution of the barrel being more or less parallel to the longitudinal axis of the structure once the strapping has been carried out, preferably.

The aforementioned characteristics of the tool according to the invention overcome all the drawbacks of the handling and dumping systems according to the prior art.

Indeed, the tool mounts very easily on the attachment device at the end of the telescopic arm, without the need for any connection to the hydraulic circuit for the actuation of said tool.

In addition, the actuation of the tool is effected by a simple tilting forwards or backwards by using the preexisting functions on the telescopic carriage which is configured to modify the angle of inclination of the device. hanging, especially for mounting traditional tools.

The tilting forwards or backwards of the tool firstly allows it to be positioned appropriately for strapping the barrel, which can advantageously be initially upright, that is to say with its axis of revolution in vertical, or lying position, that is to say with its axis of revolution in a horizontal position, or even in any initial orientation. Once this strapping is done, the tool is manipulated if necessary to put the barrel upright and thus be able to remove its cover in order to open it. The carriage is then manipulated to bring the barrel to the ball mill, then the hooking device is actuated to tilt said barrel forward until the balls it contains pour into said mill.

According to the tool object of the invention, the attachment system comprises at least two flanges parallel to each other and extending towards the rear of the structure to which they are fixed. These flanges are each provided with an upper opening and a lower opening. The upper holes define a horizontal upper axis and the lower holes define a horizontal lower axis, the upper axis being parallel and offset backwards with respect to the lower axis. The upper holes receive a hanging bar arranged along this upper axis and allowing the reception of a retaining hook on the hanging device of the telescopic carriage. In addition, the lower holes allow the reception of a pin bar between the attachment system of the tool and the attachment device of the telescopic carriage.

In an alternative embodiment of the tool according to the invention, the attachment system comprises two flanges. In another preferred variant, said attachment system comprises three flanges. A larger number of flanges could be considered.

According to the tool object of the invention, the attachment system comprises a reinforcement rail of the flanges which extends parallel to said upper and lower axes. This reinforcing rail is fixed to the structure and to the flanges.

According to the tool which is the subject of the invention, it comprises first reinforcing parts of the attachment system. These first reinforcing pieces are arranged laterally on the structure to which they are fixed. These first reinforcement pieces are also fixed to the reinforcement rail.

According to the tool object of the invention, the strapping system comprises at least two arcuate parts fixed on the front side of the structure and two straps each provided with a tightening system. The straps are arranged respectively on the two arcuate parts, between two ends on said arcuate parts.

According to the tool object of the invention, the arcuate parts have a radius of curvature greater than or equal to the radius of the barrel. Preferably, the arched parts have a flexibility allowing their deformation when tightening the straps, so as to perfectly match the shape of the barrel during strapping. One could however consider completely rigid arched parts when tightening the straps.

In one embodiment of the tool according to the invention, the straps are of the ratchet tightening strap type. One could however envisage variants of straps without departing from the scope of the invention.

In an embodiment of the tool according to the invention, the arcuate parts are dimensioned to more or less surround half of the outline of the barrel. However, provision could be made for an arcuate part dimension making it possible to surround slightly less than half of the outline of the barrel, for example about one-third of the cylindrical outline. On the contrary, provision could be made for an arcuate part dimension making it possible to surround a little more than half of the outline of the barrel once the strap has been tightened, for example two-thirds of the cylindrical outline.

According to the tool which is the subject of the invention, it comprises second reinforcing parts of the strapping system. These second reinforcing pieces are arranged laterally on the structure to which they are fixed. These second reinforcing parts are also fixed to the above-mentioned arched parts.

detailed description

The following description relates to a preferred embodiment of the tool according to the invention. This does not detail the design of the telescopic carriage receiving said tool and allowing its manipulation and that of the barrel. The design of such a telescopic carriage and in particular of its hooking device arranged at the end of the telescopic arm is already known to those skilled in the art for hooking other tools of the fork or bucket type.

As illustrated in FIGS. 1 to 5, the tool 1 comprises a structure 2 produced by means of a portion of metal rail having an I-section, the first face of the I constituting the rear side 2a of the structure 2 and the second face of the I constituting its front side 2b. The structure 2 extends longitudinally along an axis XI shown diagrammatically in FIGS. 3 to 5. The tool 1 comprises a fastening system 3 which is arranged on the rear side 2a of the structure 2, in the lower part of said structure 2 , as illustrated in FIGS. 1 to 5. This attachment system 3 comprises three plates 4, 5, 6 and a reinforcing rail 7. The flanges extend towards the rear of the structure 2. The rail reinforcement 7 comprises a U-shaped section and extends horizontally and perpendicular to the axis XI of the structure 2, as illustrated in FIGS. 1 and 2, the base 7a of the reinforcement rail 7 being welded on the rear side 2a. The flanges 4, 5, 6 are parallel to each other and extend towards the rear of the structure 2, as illustrated in FIGS. 1 to 5. These flanges 4, 5, 6 are welded to the reinforcement rail 7.

The flanges 4, 5, 6 each comprise an upper orifice 4a, 5a, 6a and a lower orifice 4a, 5b, 6b. The upper holes 4a, 5a, 6a define an upper axis X2 and the lower holes 4b, 5b, 6b define a lower axis X3. The reinforcing rail 7 is arranged parallel to said axes X2, X3. The upper orifices 4a, 5a, 6a are offset backwards with respect to the lower orifices 4b, 5b, 6b, as illustrated in FIGS. 1 to 5. The upper orifices 4a, 5a, 6a are dimensioned to receive a rod of 'hooking (not shown) on which engages a hook of the hanging device arranged at the end of the telescopic arm of the telescopic carriage (not shown). The lower holes 4b, 5b, 6b allow the pinning of the attachment system 3 on said attachment device of the telescopic carriage. The tool 1 comprises two reinforcement pieces 8, 9 arranged and welded on each of the lateral sides 2c, 2d of the structure 2 as well as on the base 7a of the reinforcement rail 7, as illustrated in FIGS. 1 to 5. This consolidates the attachment system 3 with the structure 2. The tool 1 comprises a strapping system 10 which comprises two arcuate parts 11, 12 on which are mounted respectively two tightening straps 13, 14, as illustrated by Figures 1 to 5. These arcuate parts 11, 12 are welded to the front side 2b of the structure 2. The first end 11a of the first arcuate part 11 is fixed with the first end 13a of the first strap 13. It is similarly between the first end 12a of the second arcuate part 12 and the first end 14a of the second strap 14. Two ratchet tightening systems 15, 16 on said straps 13, 14 are fixed respectively on the second ends 11b, 12 b of the two arcuate parts 11, 12. These ratchet tightening systems 15, 16 respectively receive the second ends 13b, 14b of the straps 13, 14, the actuation of said ratchet tightening systems 15, 16 allowing the tightening of said straps 13 , 14. This design makes it possible to detach the second ends 13b, 14b from the straps 13, 14 to open the strapping system 10 and position a barrel 17 against the arched parts 11, 12, then to attach said second ends 13b, 14b to the straps 13, 14 on the ratchet clamping systems 15, 16 in order to tighten the straps 13, 15 and thus the strapping of the barrel 17. When the barrel 17 is strapped on the tool 1, the axis of revolution X4 said barrel 17 is more or less parallel to the axis XI of the structure 2.

The arched parts 11, 12 are made so as to have a slight flexibility allowing them to be deformed enough to come to tighten against the cylindrical wall 17a of the barrel when the straps 13,14 are tightened. This allows better tightening. We can especially play on the material and the thickness of these arcuate parts 11, 12 in order to obtain sufficient flexibility. These arcuate parts 11, 12 also have a radius of curvature which is preferably slightly greater than the radius of the barrel 17 in the rest position, that is to say before the tightening of said straps 13, 14. By way of example , the barrel 17 comprises a diameter of 575 mm and the radius of curvature of the arcuate parts 11, 12 is 290 mm. The tool 1 comprises for each arcuate part 11, 12 two reinforcement parts 18, 19 welded respectively on the lateral sides 2c, 2d of the structure 2, said reinforcement parts 18, 19 also being welded with the arcuate part 11, 12 This makes it possible to consolidate the strapping system 10 with the structure 2.

When using tool 1 for handling a barrel 17, said tool 1 is manipulated by the telescopic carriage (not shown) so as to position the axis XI of the structure 2 substantially parallel to the axis of revolution X4 of the barrel 17 whose orientation may be arbitrary initially. The arched parts 11, 12 are then pressed against the contour 17a of the barrel 17, then the straps 13, 14 are put in place so as to encircle said barrel 17.

Once this strapping has been carried out, the telescopic carriage is manipulated to position the tool 1 with the barrel 17 in the vertical position illustrated in FIG. 3. This vertical position allows an operator to open the cover (not illustrated) of said barrel 17. The telescopic trolley is then manipulated to bring the barrel 17 in a vertical position up to the ball mill (not shown). The attachment device of the telescopic carriage can then be manipulated to pivot the tool 1 in a horizontal position illustrated in Figure 4, which allows the discharge of the balls found in the barrel, into the drum of the crusher. The telescopic carriage is then pivoted until the tool 1 reaches the inclined position illustrated in FIG. 5, which makes it possible to ensure that the barrel 17 is completely emptied.

The foregoing detailed description of a preferred embodiment of the invention is in no way limiting. On the contrary, its aim is to remove any possible inaccuracy as to its scope. Thus, numerous variants could be envisaged in the context of the invention, in particular as regards the design of the structure 2 and of the reinforcements, as regards the attachment system 3 and as regards the design of the strapping system 10.

One could for example provide an arched piece and an additional strap on the strapping system 10.

We could provide a different number of flanges on the attachment system 3.

One could also modify the dimensions of the arcuate parts 11, 12 so that they more or less surround the contour 17a of the barrel 17 when the straps 13, 14 are tightened. On the embodiment illustrated in FIGS. 3 to 5, these arcuate parts 11.12 surround a little less than half of the outline 17a of the barrel 17. They could however surround half of the outline 17a, or even a little more than half. The invention will find its application in particular for the handling of drums of balls or balls used in ball mills. However, one can consider its use for handling barrels containing other products, for example oil.
