Abstract

The "VEHICLE FOR TRANSPORTING TRACKED EQUIPMENT" to which this patent relates is a device for transporting tracked machines, and is appropriately designed to transport them on public highways, roads or in "off-road" conditions, i.e. in mining areas, comprising a hollow board or platform fitted, on both sides thereof, with independent sets of axles with wheels, in which said wheels can either be simply metal wheels or be wheels fitted with tires, in which there may be one or two wheels on each axle and there may be any number of said axles, and in which all of these axles may be drive axles or only some of these axles are drive axles while the others are simply supporting axles, so that, in any case, the number of wheels (with or without tires) appropriately distributes the weight of the load being transported over different load points to ensure this equipment satisfies legal requirements for when it is using any type of public highway, or to ensure it can withstand different terrain types when it is used off-road, in which the hollow board or platform that makes up this equipment acts as a mechanical "interface" located between the ground and the tracks of the equipment to be transported, said platform having no motor, steering system or braking system, but using the drive, steering and braking system of the tracked equipment that is being transported to move, steer and brake, as amply described in this patent, and which may also be towed by any suitable vehicle, and in which the equipment to be transported is placed on and removed from the vehicle by its own means, thereby improving on the prior art relating to the transport of large equipment that moves on metal tracks.

Description

"VEHICLE FOR TRANSPORT OF EQUIPMENT MOVING ON MATS"

Fields of this Patent:

• Reduced material, labor and transportation costs to transport crawler-moving machines.

• Extended service life of crawler tractors, excavators, drills, cranes, probes and continuous miners and other civil or military crawler machines.

State of the art.

Large equipment, such as tractors, excavators, drills, cranes, rigs, continuous miners and military vehicles, which move on crawlers and weigh up to 150 tons, cannot move on their own roads and roads. their mats would destroy the pavements or their weights would break the infrastructure, or both.

Therefore, in order to be transported from one place to another, special transportations such as platforms or boards with a number of wheels compatible with the adequacy of the loads to the resistances of the floors through which they will travel must be used; This generates high costs.

In addition, metal treadmills are expensive, short-lived parts - due to brutal loading efforts and friction in hostile environments - which cost as much as $ 1 million to pair.

Thus, although in certain cases this equipment can be moved by its own means, for reasons of economy of tracks it is preferable to be transported by other vehicles on wheels, either by using special transport to use public roads, or in spaces. off-road, as happens in mining workplaces. In general it can be said that the movement of such machines by civil roads must obey traffic laws and cannot travel by their own means, but must do so on special transport equipment. However, when locating them in an off-road environment, track wear should be avoided as much as possible.

The prior art comprises various ways of transporting these machines under off-road conditions, such as coupling wheels with tires at the end of the tracks, which are partially suspended by their own means on truck bodies. which pull them. Such types of solutions are fraught with risk to the equipment and operators involved in the practice.

Advances brought to the State of the Art by the "VEHICLE FOR TRANSPORTING EQUIPMENT MOVING ON MATS", object of this Patent.

"VEHICLE TRANSPORTING MACHINES", the subject matter of this Patent, is a machine for transporting crawler machines designed to transport them by road or on public roads or under "off-road" conditions. that is, in the mining areas, which consists of a hollow platform or plank provided on both sides with independent sets of wheeled axles, which wheels can be simply metal wheels, as well as canned wheels with wheels, the wheels on each axle can be double or single and such axles can occur in any number, and all these axles can be tractors or just some of these axles and others simply support axles, so that, In any case, the number of wheels - with or without tires - properly divides the weight of the load carried by various effort points to suit this equipment the law for when it comes to transit on public roads of any kind, or to adapt it to the resistances of various terrains, when in off-road use, and the platform or hollow board that this equipment consists of acts as a " mechanical "interface" between the ground and the tracks of the equipment to be transported, such platform being devoid of engine, steering system and braking system, but to move, steer and stay braked, uses the drive, steering and braking system of the crawler equipment being transported, as described in this Patent Report, and may also be towed by any suitable vehicle, and the equipment to be transported climbs and descends from it by their own resources, thus making advances in the state of the art concerning the transportation of large equipment moving on metal conveyors.

The "VEHICLE FOR TRANSPORTING EQUIPMENT MOVING ON MATS", object of this Patent, advances the State of the Art for the following reasons:

1. Reduces tread wear by 80% compared to non-productive equipment movement by its own means;

2. Allows the loading and unloading of equipment that moves on conveyor belts by its own handling resources;

3. Uses as its driving force the engine of the transported equipment itself;

4. Uses as steering system the steering capabilities of the transported equipment itself;

5. Uses as braking system the braking resources of the transported equipment itself;

6. There may be a variety of axles, each axle having one or two wheels, metal or tire-lined, to make the weighting of the transported load compatible with the "off-road" machine travel standards, in special transportation, by public roads, or by moving across terrain of various resistances when in mining areas;

7. Adds occupational safety to operators;

8. Adds safety and risk reduction to third parties and damage to equipment in transit;

9. The carrier object of this patent has other features such that if the crawler vehicle to be transported cannot, for any reason, be driven and, consequently, triggered, it may be towed by tractor, truck or any other suitable vehicle.

Illustrations and description of the "VEHICLE FOR TRANSPORTING EQUIPMENT MOVING ON MATS", object of this Patent.

The figures attached to this report represent the preferred embodiment of the invention, which may, within the same inventive concept, undergo specific adaptations and constructions designed to suit the numerous types of equipment that this vehicle may carry. Figure 1 is a top view of the "CARRYING MACHINE TRANSPORT VEHICLE" (1) to describe the design, composition and operation of the object of this Patent; In it we can see the chassis (2), on which the four stringers (4), mounted in two groups of two stringers (4) are fixed in any suitable way, each group of two units mounted on each side of the assembly of parts forming the "VEHICLE FOR TRANSPORTING EQUIPMENT MOVING ON TRACKS" (1), so that each two sets of two stringers (4) have placed between their two parts, coupled by the bearings (6) with or without bearings, the tractor rollers (3) and the support rollers (5), the tractor (3) or support rollers (5) being able to occur in any numbers compatible with the dimensions and the intended use of each embodiment of the object of this patent ; We also see in Figure 1 the wheels (7), in this case in unitary occurrence for each of the tractor rollers (3) and the support rollers (5), such wheels (7) can also occur in pairs for each one of the tractor rollers (3) and the support rollers (5), in which case Figure 1, for example, the wheels (7) are fitted with tires, but may be simple metal wheels, especially for when object of this Patent is transporting crawler machines in off-road areas.

In Figure 1 we also see the double-access fixed access ramps (8), each unit being placed at each of the longitudinal ends of the "EQUIPMENT TRANSPORT VEHICLE". MOVE ON TRACKS "(1), so that the angle and distance from the ground allow crawler vehicles to, on their own, climb onto the object of this patent for transportation as well as from it. come down in their destinies.

Still referring to this Figure 1, the distances between the two stringers (4) forming each set of two stringers (4) and the distances between the two sets of stringers (4) may vary widely, but in the preferred embodiment. the object of this patent, such distances correspond to the dimensions necessary for the industrial model capable of adapting to the transport of the most varied types of machines, the dimensions of which are the most common in the market.

Still Figure 1, both the support rollers (5) and the tractor rollers (3) consist of steel-core rolls of varying compositions, whether or not they may be coated with polymers with rubber-like behaviors, and they have varying diameters and lengths due to the dimensions of the equipment of which they will be part and consist of long gears with straight and parallel longitudinal teeth; It is this form of cylindrical gears with straight and parallel longitudinal teeth that causes the tractor rollers (3) to be moved in rotational motion by the linear movement of the conveyor belts that they are transporting.

It is noted from the above description of the direct rotary movement of the tractor rollers (3) by the linear movement over them, the conveyor belts of the machines being transported, the displacement of the "TRANSPORTING MACHINE MOVING VEHICLE" (1) will be in the opposite direction to that imposed by the engine of the moving equipment being conveyed; however, this is not a problem, as the speed of travel of such equipment is on average 5 km / h, the heights at which the cockpits are placed allow to see the whole surrounding environment and, for the equipment that is being transported, operating the tracks in reverse or forward mode is indifferent. Of course, placing other gears to reverse such directions of motion would entail higher prices and sources of need for maintenance.

The above description of the form of track motion transmission of vehicles being transported by the "MOVEMENT TRAVEL TRANSPORT VEHICLE" (1) provides a clear understanding that not only does such vehicle not have to be moved by its own motor, as well as its steering system is removed from the steering system of the equipment being transported, just as it is driven, that is, such equipment turns by simply reducing the speed of the conveyor belt. on the side to be turned or, consequently, by increasing the speed of the belt which is opposite to the one to be turned.

As for the braking system of the "VEHICLE FOR TRAVELING MOVING EQUIPMENT" (1), which is the subject of this Patent, it is also removed from the tracked equipment being transported, as well as the traction and handling, as , if the equipment is braked, the tractor rollers (3) will not be moved, the same as if the equipment has its engine turned off or on, but not running, when automatically the tracks, for safety reasons. from manufacturing will be braked. As described above for the description of the construction and operation of the "TRAVEL TRANSPORT VEHICLE VEHICLE" (1), its innovative operational concept is to consist of a mechanical interface placed on the ground, on wheels, positioned between the ground and track-moving equipment, which, by its own motor and braking and steerability systems, from which the interface takes advantage of these features, is therefore a low-priced and low-maintenance equipment.

Figure 2 is a side, diagonal, isometric view of the "VEHICLE FOR TRAVELING MOVING EQUIPMENT" (1), in which we see the chassis (2), a tractor roller (3), spars (4), a roll of bearings (5), bearings with or without bearings (6), some wheels (7), the fixed access ramp (8), front and the holes (10), to which the various devices used when the object of this can be coupled. Patent is towed.

Figure 3 is a side view of the "TRANSPORTING MACHINE TRANSPORT VEHICLE" (1), showing the chassis (2), a stringer (4), wheels (7) and two fixed ramps (8) and geometric relationships with the ground, and the whole set shown indicates the low height above the ground with which it moves, because in the transport of heavy loads, as are the vehicles that move on tracks, the need to maintain a Low center of gravity system is very important for transport safety.

Figure 4 is an isometric, side and diagonal view of the "TRAVEL MOVEMENT TRANSPORT VEHICLE" (1) to show it, as well as showing its necessary accessories when moving by being towed by a tractor. , truck or any suitable form; we see in this Figure 4 the chassis (2), a tractor roller (3), stringers (4), wheels (7), fixed access ramp (8), vertical floodgates (9), holes (10) and the device towing trailer (1).

Still Figure (4), the vertical gates (9) serve to make the conveyor belts of a crawler moving equipment not drive the tractor rollers (3), in the case of the "MOVEMENT TRANSPORTING VEHICLE". MATS "(1) is moved by trailer; the vertical gates (9) are removable and are inserted into vertical grooves - not shown in this Figure 4 - made over the stringers (4); As the vertical gates (9) are steel pieces of about 20 kg, they can be removed and placed by a single operator, usually the tow operator; Once the vertical floodgates (9) have been placed in place, the crawler vehicle, using one of the fixed ramps (8), climbs over and / or descends the equipment object of this patent. without touching the tractor rollers (3). In order that the "VEHICLE FOR TRANSPORTING MACHINERY EQUIPMENT" (1) does not move in reaction to the forces exerted by the up and down of the moving belt equipment which it will carry, it can be immobilized in all three ways. classic used in heavy moving machines, which are the juxtaposition of it into ravines or the juxtaposition of its wheels with portable metal wedges, of the kind widely used in mining to ensure the parking of large machines on wheels, or sturdy stone footwear; In this way, the "VEHICLE FOR TRANSPORTING MOVING EQUIPMENT" (1) will not move up or down the moving belt equipment, thus constituting a low cost manufacturing equipment and simple operation.

Figure 5 shows, in perspective, the "VEHICLE FOR TRANSPORTING MACHINES MOVING" (1) carrying a crawler excavator (S), whose boom (L) and shell (C), then After it is raised on the object of this patent, it is properly positioned on the end of the chassis (2), inserted in the place called cradle (B) and held there firmly by stabilizing its weight and the presence of its hydraulic system. ; once the boom (C) of the boom (L) is firm in the cradle (B) and its tracks (E) are driven, the reaction to the driving forces will be to make the tractor rollers (3) rotate and the "VEHICLE" FOR TRANSPORTING EQUIPMENT MOVING ON TRACKS "(1) moves in the opposite direction as the equipment would move if it were walking on the ground by its own resources; The same is true when it is the blade of a crawler tractor that fits into the cradle (B).

In the case of crawler-moving equipment to be transported there is no boom, shell or blade, as is the case with many mining machines and especially of crawler-driven military vehicles, they are simply tied with wire ropes. and or currents and the effects on the motor, steering and braking of the "VEHICLE FOR TRANSPORTING EQUIPMENT MOVING ON MATS "(1) are the same.

The attachment of crawler-moving equipment to the subject-matter of this Patent, in any way that simply takes advantage of the features of both parties, is yet another innovation in making economic and safe transportation on or off roads, any equipment moving on treadmills.

Figure 6 shows the "VEHICLE FOR TRANSPORTING MACHINES MOVING" (1) carrying the same excavator (S) as Figure 5; however, in this case, the object of this patent is being pulled by the tractor (T), which can be replaced by any suitable traction vehicle and we see in Figure 6 the presence of the vertical gates (9), the shell (C), due to the position of the boom (L) of the excavator (S) placed outside the cradle (B), allowing the coupling of the towing device (11); In this case, the crawler equipment being transported does not travel with its engine running.
