Description

POWER CONDUCTOR ELECTRIC CABLE WINDING DEVICE FOR POWERING MINING ELECTRICAL MACHINES, MOUNTED ON A STANDARD ROAD TRUCK CHASSIS.

TECHNICAL FIELD [001] This utility model descriptive report deals with a complete device, considered as an implement, mounted directly on the chassis of a standard road truck, designed to wrap or unroll power conductor cables, which are electrically powered mining machines, such as: excavators; rope shovel; crushers; drilling rig; among others, for their respective movements, used in mining environments, such as open mines (external environments) and closed mines.

TECHNICAL HISTORY [002] Generally in open and closed mines, mining machines are common, their translation movements are carried out by means of electric motors, which are powered by a conductor cable, connected to the machine and to a fixed source medium and / or high voltage, as a substation, above 4000V (Volts).

[003] These conductor cables have diameters (gauges) above 40mm, reaching up to 100mm, which are coated with insulation capable of withstanding such working voltage (Volts), implying these high, making it difficult to handle them manually, when extended over the uneven, abrasive and cutting floors of the mines, which can cause damage to these elements.

[004] During the translation movement of the mining machines, these cables are deposited on the floor, and these elements must constantly be moved to the sides, or rolled or unrolled in large spools, resulting in the need for a team dedicated to workers, who are exposed to conditions of high accident risks and excessive physical efforts.

[005] Document PI39105544A describes and discusses this problem in detail, proposing an electric cable winding device for excavator or other equipment, as a measure to avoid and eliminate as much as possible the adoption of

Petition 870190008391, of 01/25/2019, p. 12/67 / 26 workers in this type of work activity, equipping the mining machine with a device for winding or unwinding its respective power conductor cable.

ANALYSIS OF THE STATE OF THE TECHNIQUE [006] As presented in document PI9105544A, the proposed system has advantages, such as: saving time in this type of operation; increased productivity of the mining machine; significant reduction in damage and increase in the life of the conductor cables exposed on the floor; reducing the risks of accidents with workers.

[007] However, such solution presented in document PI9105544A, has limitations in the mining operation, as such equipment must be coupled (fixed) to a mining machine, as it is not a device inherent to the machine's design, characterized by only constructive adaptation.

[008] Another limiting factor resides in the machine's translation capacity, as the distance to be traveled will depend on the length of the coiled conductor cable, which is deposited behind the machine, generating risks of serious damage to it, and in case it needs to be extended at the machine's transfer distance, there is a need to add a new extra amount of conductor cable to serve as an extension, and its introduction requires equipment shutdown and shutdown and decreased productivity.

[009] In some mines, due to the use of the equipment proposed in document PI 9105544A and commented in [006] to [008], they adopt another more practical solution, because instead of working with a coil coupled to the machine, winding and unrolling its respective conducting cable, in a semi-automatic and / or manual way, here the conducting cables start to be deposited and positioned on the floor, as extensions, which are electrically connected to the machines.

[010] However, this second solution presented in [009], brings some drawbacks, as there are difficulties in the operation of winding and unrolling these cables deposited along the passage of the machines, which consequently increases the efforts of workers handling them.

DETAILED DESCRIPTION OF THE OBJECT [015] With reference to the illustrated drawings, the present utility model refers to a “WINDING DEVICE FOR ELECTRIC POWER CONDUCTING CABLES, SUPPLYING ELECTRIC MINING MACHINES, MOUNTED ON A STANDARD ROAD TRUCK CHASSIS” , more precisely, it is a modular equipment, consisting of means for winding and unwinding conductor cables in coils (11) (figure 5a), in a safe, economical, effective way and without human efforts.

[016] According to the present utility model, the Winding Device (DE) basically comprises of 2 large sets: the implement (2) (figures 2a and 3a) and the articulated crane (10) (figures 3a and 3b), where each The set has specific functions within the operation of winding and unwinding conductive cables in open and closed mines.

[017] The implement set (2) consists of the subsets of: sobrechassi (4); winder skid (5); operating cabin (6); cable guide arm (7); retractable walkways (8); easel (9) (figure 2a).

[018] The basic operation of the Winding Device (DE) is to wind and unwind de-energized conductor cables (12) spread over the mine floor, on a coil (11) (figure 4), positioned at the rear of the implement (2) and coupled mechanically to the winder skid (5) (figure 6).

[019] The winding of the de-energized conductor cable (12) is carried out by the command of an external operator (13), who accompanies the vehicle on foot, which by means of a radio control system, controls the necessary arm movements

Petition 870190008391, of 01/25/2019, p. 20/67 / 26 cable guide (7) (right or left, up and down), in order to reach the de-energized conductor cable (12) deposited on the mine floor, positioning it without human effort as much as possible near the rear of the truck (1) (figure 7).

[020] The vehicle, in turn, moves at low speed (between 3 to 6 km / h), both forward and reverse, as the purpose of reaching the de-energized conductor cable (12) spread over the floor and by aid of the cable guide arm (7) guide it to the coil (11) (figure 7), where it will be wound.

[021] When completing the winding of the de-energized conductor cable (12), on the coil (11), it can be removed from above the winding skid (5), by means of the articulated crane (10), and positioned both somewhere the floor, as in the front of the implement (2), the choice of the external operator (13), specifically, on the easel subset (09) (figure 8a), keeping this coil (11) loaded (in stock ”) in I await another need for use.

[022] The function of the articulated crane assembly (10) in the Winding Device (DE) is to remove, place and position the coil (11), both in the subset of the winding skid (5) (figure 9a) or the trestle (9) (figure 9b), as well as at any point on the floor that the boom (14) and the load capacity of the articulated crane assembly (10) allow to reach (figure 9c).

[023] Similarly, the unwinding process has the same characteristics as the winding, however, the coil (11), rotating in the direction of unwinding, releasing the de-energized conductor cable (12) on the floor in the desired path, under the command of the external operator (13).

[024] Therefore, the descriptions between [018] to [023] illustrate the basic operations of the Winding Device (DE), which are intended to make the conductor cables (12) available in the desired positions to be used in the feeding operation mining machines, as well as collecting them in coils (11), to prevent damage to these conducting cables (12), where all these movements are autonomous.

[025] For better understanding of the description, the subframe (4) (figure 10a) is a steel structure, composed of two side members (15) and crosspieces (16), with U-shaped profiles (figure 10b), duly welded together, whose main function is to serve as

Petition 870190008391, of 01/25/2019, p. 21/67 / 26 connecting element to the implement (2) and articulated crane (10) assembly, with the chassis structure (3) of the truck (1), by means of mechanical fasteners (screws, nuts and washers) ( figures 2a, 3a and 3b).

[026] Another advantage of the subframe (4) is to facilitate the complete assembly and disassembly of the implement assembly (2) and the articulated crane (10), quickly, without changing the chassis (3) of the truck (1), allowing the reversibility of the truck (1) in its original form (figure 1).

[027] The coil (11), in turn, is a subset of the implement (2), removable and transportable, in the form of a spool, whose function is to serve as a basis for winding (winding) or unwinding (unwinding) ) conductive electrical cables (12) of different diameters (gauges) and lengths, in an orderly (spiral) (figure 4), consisting of the elements: winding cylinder (17), octagonal sides (18A) and (18B), crown ( 19), the axis (20) and the shaft ends (21A) and (21B) (figures 5a and 5b).

[028] The winding cylinder (17) consists of a thick calendered steel plate, where the edges C and D do not close (do not meet), in order to maintain this distance, a gap, for the passage and fixation of a the ends of the conductive cable (12), inside as shown in the detail of figure 5b.

[029] The calendered edges E of the winding cylinder (17), are fixed to the octagonal sides (18A) and (18B), which are constituted by a metallic structure of plate and rectangular steel tubes, where all these elements are joined by welding or other equivalent mechanical joining means.

[030] The shape of a polygon with 8 sides (8 edges) on the octagonal sides (18A) or (18B) has the purpose of better supporting the coil (11) on the floor, and thus preventing its rotation. [031] On the octagonal side (18A) [right side] there is a steel gear, called a crown (19), fixed concentrically with a winding cylinder (17), whose purpose is to rotate the coil subset (11) (direction clockwise or counterclockwise) when engaged (coupled) with the gear (pinion) (26), located on the winder skid (5); in turn, this crown (19) is joined to the octagonal side (18A) [right side] by means of welding or other means of mechanical joining.

[032] Next to the 8 edges of each of the octagonal sides (18A) and (18B), there is a

Petition 870190008391, of 01/25/2019, p. 22/67 / 26 slot F, in order to serve as a lifting point for the coil subset (11), when it has to be lifted and moved by the articulated crane assembly (10).

[033] An axis (20) is mounted on the center line of the winding cylinder (17), consisting of a steel tube, duly joined by welding, perpendicularly to the octagonal sides (18A) and (18B) (figures 5a and 5b ), having at their ends the shaft ends (21A) [right side] and (21B) [left side].

[034] The shaft ends (21A) and (21B) are elements made of a machined steel cylinder, joined concentrically to the shaft (20) and fixed externally on each octagonal side (18A) and (18B), by means of welding or other equivalent mechanical means of connection, as shown in figure 5a.

[035] Each shaft end (21A) and (21B) has a recess G on the side surface of the cylinder body (detail BB of figure 5b), whose diameter (depth) and width correspond to the same dimensions as the lower half cane A of the respective bearings (25A) and (25B) (figure 6), where such recess G serves as the point of attachment of the coil subassembly (11) on the sides (23A) and (23B) of the winder skid subassembly (5).

[036] Thus, all the elements described from [027] to [035] make up the coil subset (11), which when properly joined together, form a single rigid component, capable of carrying out its function, that of serving as base for winding unpowered conductor cables.

[037] The skid reel assembly (5) is a device, in the shape of an open box at the top, positioned at the rear of the implement (2) (figures 11a 11b), and fixed on a turntable (22).

[038] The skid winder subset function (5) is to support and move the coil (11) (figures 12a and 12b) clockwise and counterclockwise, loaded or unloaded, this subset consisting of a metallic structure in sheets, tubes and steel profiles, properly welded to each other or another equivalent mechanical means of joining, consisting of: lateral (23A) and (23B); platter (23C); floor (23D) and the indexer assembly (24) (figure 6).

[039] The sides (23A) and (23B) are shaped like an irregular pentagon, the base being

Petition 870190008391, of 01/25/2019, p. 23/67 / 26

H supported and fixed on the turntable (22), constructed of folded steel sheets, which are spread among themselves over the longitudinal (symmetry) plane of the truck (1), which are joined by welding or by other equivalent mechanical means of union the crosspiece (23C) at the front and the indexer assembly (24) (figure 6).

[040] The sleepers (23C) are constructed from folded steel sheets, as shown in figure 6, determining the width of the skid-roller subset (5).

[041] On the sides (23A) and (23B) there are two bearings (25A) and (25B), similarly split horizontally, whose function is to support the shaft ends (21A) and (21B) of the coil ( 11), as shown in figure 5b.

[042] When fitting the recess G of the shaft ends (21A) and (21B) of the coil (11) (figure 5b), on the lower half cane A of the bearings (20A) and (20B), the operator positions the other upper half-cane B contained in the sleepers (28) (figure 6) on the shaft ends (21A) and (21B), with the purpose of locking any vertical movement of the coil (11) in the respective bearings (25A) and (25B ).

[043] Inside the side (23A) there is a pinion (gear) (26), coupled to a motor (29) (figure 11b), which can be hydraulic, electric or pneumatic, whose function is to transmit energy to move (rotate) the coil subset (11), by means of a gear (pinion) (28) with the crown (19) (figure 12c). [044] The motor speed regulation (29) and its direction of rotation (clockwise and counterclockwise) are defined by the external operator (13) during the rolling or unwinding process.

[045] The indexing assembly (24), in this case, has the function of laterally moving, in an alternative movement (back and forth), the conductor cable (12), winding or unwinding it over the coil subset (11) with pitch constant P [where P is equal to the diameter of the conductor cable (12) (figure 8a)], both for the right side and for the left, which is positioned at the rear of the winder skid subset (5) and joined to the sides ( 23A) and (23B).

[046] Initially, the indexer assembly (24) consists of a metallic structure, called the support box (30) (figure 13a), composed of: an A beam (30A), consisting of an L profile with the same flap steel, thick and folded; a B beam

Petition 870190008391, of 01/25/2019, p. 24/67 / 26 (30B), consisting of an L profile of uneven steel flap, thick and folded; two rails (30C), consisting of a C profile with a single flap, thick and folded; and 2 connection profiles (30D), consisting of a thick and bent steel C profile, all of which are characterized mechanical elements, identified in the exploded view, illustrated in figure 13b.

[047] Beam B (30B), in turn, supports its smaller flange on the horizontal flange of beam A (30A), coinciding the respective Z and X edges in the same line and direction, forming a U profile, as shown arranged in the exploded view of figure 13b, for better understanding, all these elements being joined by means of welding or other equivalent mechanical means of connection.

[048] Joined internally on the vertical flaps of beam A (30A) and beam B (30B), in the direction of edges Y and W, there are two rails (30C) fixed to these by means of welding or other equivalent mechanical joining means , arranged according to figure 13b, having the function of supporting the indexing carriage (32) (figure 14d) during the winding process.

[049] The vertical tabs of beam A (30A) and beam B (30B), in this sense, are braced (locked) in their upper part by the 2 connection profiles (30D) by means of screws, to facilitate the assembly of others internal mechanical elements, to be described and claimed, which are also part of the indexing assembly (24) (figure 14a).

[050] The indexer assembly (24), in this case, consists of: vertical rollers (31); indexing carriage (32); indexing driven gearwheel (33); stretcher (34); indexing motor sprocket (35); driven sprocket (36); intermediate indexing gear (37); drag pin (38); gearbox “gearbox outlet” (39); tensioning gear (40); indexing chain (41); “reducer inlet” sprocket (42); intermediate transmission current (44); and the drag rail (45), all elements arranged according to figures 14a and 14b.

[051] The operation of the indexer assembly (24) (composed of the elements described in [045] and [050]) starts with the energy source transmitted by the motor (29), installed externally on the side (23A) [right side] of the winding skid (5), which has a toothed wheel attached to its output shaft, next to and behind the pinion (26)

Petition 870190008391, of 01/25/2019, p. 25/67 / 26 motor (43) (figures 14a and 14b), which transmits this rotation (clockwise or counterclockwise) to the gearbox inlet gear (42), through the intermediate transmission chain (44).

[052] From the “reducer inlet” sprocket (42), the indexer assembly (24) starts, which in turn is coupled to the reducer input shaft (27), installed and fixed externally in the box support (30) and inside the winder skid assembly (5) (figure 14a), which reduces the rotation and transmits the turning movements to the “reducer output” gearwheel (39), up to the gearwheel moved (36) by means of the intermediate chain (46), both installed and disposed under and externally the support box (30) (figure 14a).

[053] At this moment, the driven gear wheel (36) transmits the rotation to the indexing motor gear wheel (35) (figures 14a and 14b), using the shaft (47) of the bearing (48), common to both.

[054] The indexing motor sprocket (35) has the function of transmitting the movement to the indexing driven sprocket (33) and the indexing intermediate sprocket (37) (figure 14b) through the indexing chain (41) (figure 14c ).

[055] The indexing driven toothed wheel (33), at this moment, is coupled by its stretcher axis (34) (figure 14a), whose function of the latter is to keep the indexing chain stretched (tensioned) (41), being that intermediate indexing gear (37), which in this case serves to provide stability and support to the movement of the indexing chain (41) in the center of the path.

[056] The indexing chain (41) is also characterized by having a drag roller (38) on one of its links, where its axis is fixed rigidly to this link.

[057] The purpose of this drag roller (38) is to serve as a drag element (in the direction of pulling, moving) of the indexing chain (41), which will fit (engage) in the drag track (45), as illustrated in figure 14c.

[058] The drag rail (45) (figure 14c) consists of a U profile, facing downwards, made of steel, fixed rigidly under the indexing carriage (32) and positioned (longitudinally) in the direction perpendicular to the movement of the indexing chain (41), where in this direction there is the necessary degree of freedom for the movement of the roller

Petition 870190008391, of 01/25/2019, p. 26/67 / 26 drag (38) inside it.

[059] When the indexing chain (41) moves, the drag roller (38) attached to it, touches and pushes one of the tabs of the U profile of the drag rail (45) in the same direction of movement, due to the coupling between both, thus producing a movement of the indexing carriage (32), that is: when the drag roller (38) is moving linearly and constantly to the left, the indexing carriage (32) goes to the left; when the link of the indexing chain (41), which contains the drag roller (38), passes through the driven indexing gear (33), the linear movement of the drag roller (38) stops and inverts to the right, and consequently the carriage indexer (32) stops and moves to the right too; and when the link of the indexing chain (41) passes through the indexing motor gearwheel (35), the linear movement of the drag roller (38) stops and reverses to the left again, and the indexing carriage (32) also moving to left.

[060] The movements of the elements described in [059], produce an alternative movement (back and forth) of the indexing carriage (32), which moves on the 4 rotating rollers (49) guided on the lower flaps of the C profiles of the rails (30C) of the support box (30) (figure 14d).

[061] The direction of rotation of the motor (29) does not influence the reciprocating movement of the indexing carriage (32), but only in the direction of rotation of the coil (11), which may be in the direction of winding or unwinding the conductor cable (12 ).

[062] On the upper part of the indexing carriage (32) there is the set of vertical indexer rollers (31) (figure 14d), both solid and rigidly connected to each other, whose function is to guide and keep the P step constant (figure 8a) when winding and unwinding the conductor cable (12).

[063] The set of vertical rollers for the indexer (31) consists of: roller fixing brackets (50A); support bracket (50B); and 2 vertical rotating rollers (50C).

[064] All information between [037] to [063] corresponds to the description of the skid-roller subset (5), which is attached and attached to the turntable (22) (figure 11a), responsible for rotating all this subset

Petition 870190008391, of 01/25/2019, p. 27/67 / 26 to the right or to the left (figures 11b and 11c), to facilitate the operation of winding or unwinding the conductor cables (12) on the mine floor.

[065] The turntable (22) has the function of serving as a base for fixing the winder skid subsets (5), the operator's cabin (6), the cable guide arm (7) and the retractable walkways (8) (figure 15), and consists of 3 elements, being: the support base (22A); swivel base (22B); and the central pivot (53) (figures 16a, 16b and 16c). [066] In figure 17, the support base (51) is composed of a rectangular tubular steel structure, with its elements welded together, consisting of: support frame (51A); diagonal sleepers (51B); longitudinal crosspiece (51C) and fixing base (51D) of the cable guide arm subset (7), making it a rigid structure to guarantee its purpose.

[067] Fixed rigidly at the intersection of the diagonal crosspieces (51B), at the bottom, there is a central pivot (53) (figure 16c), whose purpose is to serve as the axis of rotation of the support base (51), composed of 2 elements: the octagonal fixing base (53A) and the geared shaft (53B).

[068] The octagonal fixing base (53A) consists of a steel plate thick enough to withstand the mass of all subsets added to the turntable (22) (figure 15), which is mechanically joined by its center, with the shaft engaged (53B), as illustrated in figure (16C), this part being built from a solid steel bar.

[069] Approximately in the center of the stepped surface of the meshed shaft (53B) there is a spur gear M (can be teeth with other configurations, without detracting from this utility model), as shown in figure 16c, whose function is to engage with the rack rods (52C) (figures 18a and 18b), to perform the lateral movements described in [064].

[070] The surface J of the rotating base (52) (figure 18a), in turn, is the plane that rests and rotates the support base (51), the surfaces K on which this device rests is fixed on the sub-assembly of the subframe (11) by means of mechanical fasteners.

[071] The swivel base (52) is also characterized by:

Petition 870190008391, of 01/25/2019, p. 28/67 / 26 support (52A); by 4 cylinders (52B); by 2 rack rods (52C); and by 4 pistons (52D), arranged according to figure 18a.

[072] The support box (52A) is a closed enclosure (figure 19) built from welded steel sheets, whose function is to house and fix the 4 hydraulic cylinders (52B) on its side.

[073] Each cylinder (52B) has a piston inside (52D), which is coupled with one of the ends of the rack rod (52C), arranged according to figure 18a, which after assembling these elements in the support box (52A) form the rotating base assembly (52), being arranged according to figure 18b for better understanding.

[074] When meshing the straight teeth M of the geared shaft (53B) in the teeth of each rack-rod (52C) (figure 18b), all this assembly allows the turning movement (clockwise or counterclockwise) of the turntable ( 22) is carried out.

[075] Therefore, when pressurizing the R inlets with hydraulic oil in each cylinder (52B), (pressure Pr from a hydraulic unit), Fei and Fe2 forces (where Fei> Fe2) appear, acting on each piston (52D) , as illustrated in figure 18b, thus producing linear movements of the same direction of the forces in each rack-rod (52C); as a result, there is a torque of forces Fr acting on the teeth of the spur gear on the geared shaft (53B), generating a torque T and a turn on the geared shaft (53B) of the turntable (22), and consequently the skid winder subset (5); if you change the pressurization for the S inlets on each cylinder (52B), the direction of rotation of the turntable (22) is reversed.

[076] The ability to turn (angle) the winder skid subset (5) to the sides (clockwise or counterclockwise) is limited by the stroke of the piston (52D) inside the cylinder (52B), that is, throughout the mechanism understood and arranged in figures 18a and 18b.

[077] All information between [065] to [076] corresponds to the description of the turntable (22), responsible for supporting and rotating the subset of the roller skid (5) to the right or to the left (figures 11b and 11c), to facilitate the operation of winding or unwinding the conductor cables (12) on the mine floor. [078] To collect and deposit the conductor cable (12) more efficiently on the mine floor, in order to be able to reach it easily without the use of human force, it is installed

Petition 870190008391, of 01/25/2019, p. 29/67 / 26 a cable guide arm (7) (figure 7), capable of extending, moving horizontally (right or left) and vertically (up and down) (figure 20).

[079] This subset consists of the parts: flange (54); fixed arm support (55); pivot pin 1 (56); fixed arm (57); extension arm (58A); guide roller assembly (59); hydraulic lifting actuator (60); hydraulic extension actuator (61); hydraulic side swing actuator (62); pivot pin 2 (63); and the hinge pin 3 (64).

[080] This whole subset of the cable guide arm (7) is fixed by the flange (54), using mechanical fasteners (screws, nuts and washers) on the fixing base (51D) (figure 17), at the rear of the implement (2) (figure 7).

[081] The flange (54) is an element constructed from folded and welded steel sheets, as shown in figure 21, with the purpose of serving as a vertical bearing for the fixed arm support (55) (figure 20).

[082] The fixed arm support (55), in turn, is fixed to the flange (54) by means of the articulation pin 1 (56), which defines the articulation axis A1, which allows this element to rotate horizontally (left or right), also having as function of fixation point: the fixed arm (57); the hydraulic lifting actuator (60); and the side swing hydraulic actuators (62), as shown in figure 20.

[083] In this sense, this fixed arm support (55) consists of thick steel plates, welded together, arranged according to figure 22 for better understanding, and composed of: horizontal flaps (55A) which has the articulation axis TO 1; the vertical flaps (55B), which have the articulation axes A2 and A3; and the 2 lateral articulation supports (55C), which have the articulation axis A7 (figure 20).

By the articulation axis A2, the fixed arm support (55) interconnects with the fixed arm (57), joined by the articulation pin 2 (63), and by the articulation axis A3 interconnects with one of the ends of the actuator hydraulic lift (60) by pivot pin 3 (64).

[084] Through the articulation axis A7, the fixed arm support (55) is connected to the rod ends of the side swing hydraulic actuator (62), using the articulation pin 7 (67), as provided in the figures 20 and 22.

Petition 870190008391, of 01/25/2019, p. 30/67 / 26 [085] The fixed arm (57) consists of: a thick wall steel tube (57A), with a hexagonal cross-section, with constant dimensions along its length, having in one of the its ends the articulation axis A2; of the fixing support 4 (57B) constituted from a thick steel plate, characterized by the shape of figure 23, located and welded close to the other end of the tube (57A), with the function of serving as an interconnection point with the other end of the hydraulic lifting actuator (60) by the pivot shaft A4, joined by the pivot pin 4 (65); and the smaller fixing bracket 5 (57C), made up of steel plates, welded at the bottom of the tube (57A), being responsible for the point of interconnection of one end of the hydraulic extension actuator (61) by the articulation shaft A5 , joined by the hinge pin 5 (66) (figures 20 and 23).

[086] Coupled inside the tube (57A) is the extension arm (58A), responsible for increasing or decreasing the total length of the cable guide arm subset (7), a movement exemplified in figure 24A, which consists of a hexagonal steel tube or other regular polygonal shape, the external dimension of which is slightly smaller than the internal dimensions of the tube (57A), so that there are minimum clearances to allow the relative free movement between them; by the fixing bracket (58B), attached to the extension arm (58A), whose function is to connect to the other end (of the rod) of the hydraulic extension actuator (61), as characterized in figures 20 and 24B, through the articulation pin 6 (68), defined by the articulation axis A6.

[087] Attached rigidly to the upper end of the extension arm (58A), there is the guide roller assembly (59) for the purpose of guiding and maintaining the conductor cable (12) at the end of the cable guide arm subset (7), as exemplified and visualized by figure 7.

[088] The guide roller assembly (59) consists of the following parts: lower roller support frame (59A); 2 vertical rollers (59B); lower horizontal roller (59C); upper roller support crosspiece (59D); horizontal upper roller (59E) and lever (59F), arranged according to figure 25.

[089] The support frame for the lower rollers (59A) is a structure characterized by

Petition 870190008391, of 01/25/2019, p. 31/67 / 26 present a U-shape, fixed rigidly by welding on the upper part of the tube (58A), constructed by steel plates welded together, whose purpose is to fix the axes of the 2 vertical rollers (59B) and the horizontal roller bottom (59C), configured in figure 26A, so that the conductor cable (12) lays and slides without resistance on these 3 elements, guiding it by the end of the cable guide arm subset (7) (figure 26B). [090] Connected with the lower roller support frame (59A) there is the upper roller support crosspiece (59D) (figure 25) to fix the upper horizontal roller axis (59E), as seen in figure 26C, articulated by the articulation pin 8 (59G) (articulation axis A8), which can be removable or not.

[091] The upper roller support beam (59D) is also made of steel plates, welded together, arranged as shown in figure 25, with a lever (59F) opposite the articulation pin (59G), rigidly attached to this first element, whose intention is to serve as a handle for opening and closing the upper roller support beam (59D) on the lower roller support frame (59A). [092] The removable locking pin 9 (59H) (pivot shaft 9) (figure 25) has the function of joining and closing the lower roller support frame (59A) with the upper roller support beam (59D), when fitted at this end with each other, it allows the conductor cable (12) to be guided safely, housing it and sliding it in the middle of the 4 rollers (59B), (59C) and (59E) already described.

[093] In this way, each movement of the cable guide arm subset (7) can be characterized by the extension and retraction movements of the hydraulic lifting actuators (60), hydraulic extension actuator (61) and the hydraulic actuator of lateral rotation (62), arranged according to figure 20.

[094] The vertical SD movement (up or down), as seen in figure 20, of the cable guide arm subset (7) occurs when the hydraulic lifting actuator (60) extends or retracts, changing the distance between the articulation axes A3 and A4, consequently, causing the fixed arm (57) to rotate up or down, respectively, around the articulation axis A2.

[095] The lateral turning movement GL (right or left) of the cable guide arm subset (7) occurs when the hydraulic lateral turning actuator (62), extend

[096] The extension or retraction movement ER (right or left) of the cable guide arm subset (7) occurs when the hydraulic extension actuator (61), extends or retracts, changing the distance of the articulation axes A5 and A6, consequently, causing the extension arm (58A) to slide inside the tube (57A) (figure 24A), increasing or decreasing the length of this entire subset.

[097] All information between [078] to [096] corresponds to the description of the subset of the cable guide arm (7), responsible for facilitating the collection or deposit of the conductor cables (12) on the floor of open mines or closed, in order to facilitate the rolling or unrolling operation.

[098] To facilitate the operation of preparing the operation of winding or unwinding conductor cables (12) on the floor of open or closed mines, or to verify that the coil assembly (11) is correct, or the need for some type of corrective or preventive maintenance on the skid roller (5), 2 subsets of retractable walkways (8) are installed, in order to provide safe working conditions to the operators of this equipment, which are supported on the right and left sides of the platform structure (22) (figures 27a and 27b).

[099] The subsets of the retractable walkways (8) are composed of the parts: 2 walkways (69); 2 guardrails (70); 2 tilting stairs (71); 4 square rods (72); and the 4 hydraulic extension actuators (74).

[100] The walkway (69) is constructed from L profiles and steel sheets, welded together, characterized as shown in figure 28, which has a rigidly attached guardrail (70), which is consisting of a flat portico formed of round steel tubes, welded together.

[101] At the end of the walkway (69), which corresponds to the rear of the implement (2), there is a tilting ladder (71), articulated at points T and U, whose purpose is to give the operator easy access to the upper surface of the walkway (69).

Petition 870190008391, of 01/25/2019, p. 33/67 / 26 [102] At the bottom and supporting the walkway (69) transversely, there are 2 square rods (72), consisting of thick tubes or solid square steel bars, which fit inside the respective guide tubes ( 73), located at the bottom of the support frame (51A) (figure 16a).

[103] Through this fitting, the square rods (72) slide inside guide tubes (73), allowing the walkway (69) to move away from or close to the side of the turntable (22), a movement performed by the 2 hydraulic actuators of extension (74) (figure 27b), which work simultaneously and coordinately to prevent tangling or locking of this subset.

[104] All the information contained between [099] to [103] corresponds to the description of the subsets of the retractable walkways (8), whose purpose is to facilitate the ones on the skid roller (5) safely.

[105] When lifting the coils (11) (figures 9a, 9b and 9c), the operator can operate from the articulated crane assembly (10), both on the outside and inside the operator's station (6), where all commands are carried out by means of a remote control system, which always accompanies the operator.

[106] The operator's cabin (6) is rigidly attached to the front side of the turntable (22), in front of the roller skid (5), where the height [seated inside the operator's cabin (6)] allows the operator can have a view of the lifting operation area in order to perform it safely (figure 29a).

[107] The operator's station (6) (figure 29b) can present several construction methods, as exemplified in this utility model, by a tubular metallic structure, covered by steel plates, and by impact resistant windshields (75) , protected by steel bars (76), with the function of protecting the operator inside against the dangers inherent in the lifting of coils (11).

[111] The function of the fixed platform (77) is to serve as a support area around the trestle structure (78), in areas Si and S2, which are protected, respectively, by the front guardrail (79) and the guard rear body (80) as a means of securing the operator's work.

[112] Attached to this fixed platform (77), there are 4 fixed stairs (81) arranged according to figure 30, positioned in each corner of the right and left sides, as a means of access to the upper part of the easel subset (9).

[113] Both the front guardrail (79), the rear guardrail (80) and the stairs (81), are made up of tubular and round steel profiles, welded together, forming together with the fixed platform (77) a single rigid set.

[114] Attached to the front guardrail (79), there is the rocker arm support (82), constituted of a tubular structure or otherwise constructive, capable of supporting and guarding the rocker arm (83) (figures 9a, 9b and 9c), aid element to be used in the lifting operations of the coils (11).

[115] The rocker arm (83) is a solid or tubular steel bar, with a hook (84) at each end to fit one of the coil's F slots (11) (described in [031]) (figure 5a), and having an eye (86) in the center as the lifting point of the boom hook (14) of the articulated crane assembly (10) (figure 9a).

[116] On the fixed platform (77), the frame of the easel (78) is rigidly attached, joined by means of welding or other equivalent mechanical connection, with the responsibility of supporting the loaded coil (11) or not, safely, as shown in figure 8a.

[117] The structure of the easel (78), in turn, is formed: by the vertical sides (78A) and (76B); by 2 sleepers (78C); and the floor (78D), all made of folded steel sheets, joined by welding or by another means of equivalent mechanical union,

[119] Each crosspiece (78E) is articulated by articulation axes A10 and A11, has the function of locking the coil (11) securely over this entire subset described.

[120] Therefore, using the information contained in [109] to [119] corresponds, the description of the subset of the easel (9), responsible for supporting and storing a coil (11) loaded or not with a conductor cable (12).

[121] To correctly move and position the load, composed of the coil (11), anywhere on the mine floor or on the winding skid (5) or subset of the easel (9), this equipment has an articulated crane assembly ( 10) suitable for lifting and handling this load (figure 3a).

[122] The articulated crane assembly (10), in this case, is standard equipment in the market, capable of lifting and moving a loaded coil (11) over a certain safe distance by means of its boom (14) (figure 3a ), controlled by an operator externally or inside the operator's station (6).

[123] The articulated crane assembly (10) is fixed using mechanical fasteners (screws, nuts and washers) in the center of the truck's chassis (3) (1), supported on the subframe sub-assembly (4), to promote rigidity between these sets.

[124] Two retractable shoes (87), when extended (figure 9a) provide stability and lateral support to the equipment when lifting and moving loaded or unloaded coils, which can be operated hydraulically, electrically or mechanically (manually) .

[125] All information contained in [015] to [124] corresponds to the description of the implement sets (2) and their constituted elements, and the articulated crane set (10) to be claimed, as an innovative utility model.
