Description
TITLE OF THE INVENTION
Rod handier.
FIELD OF THE INVENTION
The present invention relates to the field of rod handlers.
BACKGROUND OF THE INVENTION
Many existing rods are typically relatively long hollow rods that are secured to each other, for example for drilling a bore. These rods are typically relatively heavy and relatively cumbersome to handle. Therefore, many devices have been designed to handle these rods.
Prior art rod handlers typically include a hydraulic clamp which is attached to an arm that is typically hydraulically actuated. However, these rod handlers are typically relative expensive as they include many mechanical parts and costly and complex hydraulic systems. In addition, these rod handlers are typically relatively large and heavy and are therefore typically installed permanently at a site at which rods must be handled. Therefore, there is need to have a distinct rod handler for each site at which rods are manipulated.
In addition, the rod handlers need to be operated remotely by an operator who needs to be relatively highly trained so as to be able to operate the apparatus. Yet, furthermore, handling the rods with these apparatuses is a typically relatively complex task and there is a need to ensure that the rods do not hit any surrounding equipment.
In view of the above, there is a need in the industry to provide novel and improved rod handler.
SUMMARY OF THE INVENTION
In a first broad aspect, the invention provides a rod handler for handling a rod. The rod handler includes a handler base and an arm mechanically coupled to the handler base. The arm is pivotable in a substantially vertical plane relatively to the handler base. A rod receiving platform is provided for receiving the rod. A
platform attachment is operatively coupled to the arm and to the rod receiving platform for maintaining a substantially predetermined angular relationship between the rod receiving platform and the handler base when the arm is pivoted in the substantially vertical plane. The rod receiving platform is removably attachable to the platform attachment.
In some embodiment of the invention, the platform attachment is operatively coupled to the arm and to the rod receiving platform for maintaining the rod receiving platform substantially horizontal when the arm is pivoted in the substantially vertical plane.
Advantageously, the rod handler according to the invention is relatively inexpensive to manufacture using readily available parts. Furthermore, the rod handler is typically relatively simple to operate in a few relatively simple, fast and ergonomic steps.
Yet, furthermore, the rod handier according to the invention may be manufactured so as to be relatively easily movable between different rod handling stations, which decreases ownership costs when manipulating the rods at a site in which rods have to be handled at many locations.
Yet, furthermore, the rod handler is typically relatively easy to use without requiring extensive training.
Having a detachable rod receiving platform allows to manipulate rods having many different diameters as the rod receiving platform may then be changed relatively easily to accommodate these rods having different diameters.
Other objects, advantages and features of the present invention will become more apparent upon reading of the following non restrictive description of preferred embodiments thereof, given by way of example only with reference to the accompanying drawings.

DETAILED DESCRIPTION
Figs. 1 to 4 illustrate a rod handler 10 for handling a rod 12. The rod handler 10 includes a handler base 14. An arm 16 is mechanically coupled to the handler base 14. The arm 16 is pivotable in a substantially vertical plane 18 (better seen in Fig.
4) relatively to the handler base 14. The rod handler 10 also includes a rod receiving platform 20 for receiving the rod 12. A platform attachment 22 is operatively coupled to the arm 16 and to the rod receiving platform 20 for maintaining a substantially predetermined angular relationship between the rod receiving platform 20 and the handler base 14 when the arm 16 is pivoted in the substantially vertical plane 18. The rod receiving platform 20, in some embodiments of the invention, is removably attachable to the platform attachment 22.
Having a rod receiving platform 20 that is removably attachable to the platform attachment 22 allows to change the rod receiving platform 20 so that a suitable rod receiving platform 20 is used with rods 12 having different diameters. Since only a relatively small portion of the rod handler 10 is changed when the rods 12 used change diameter, it is relatively inexpensive to have a rod handler 10 that may handle rods 12 having diameters varying over a relatively wide range.
Therefore, there is no need to have a hydraulic clamp for clamping the rods 12, which are commonly used in prior art rod handlers, in the rod handler 10.
In some embodiments of the invention, the platform attachment 22 is operatively 5 coupled to the arm 16 and to the rod receiving platform 20 for maintaining the rod receiving platform 20 substantially horizontal when the arm 16 is pivoted in a substantially vertical plane 18, as seen in Fig. 3. In these embodiments of the invention, the rod 12 is then relatively easily supported in a stable manner onto the rod receiving platform 20 when the rod handler 10 is used to lower or to raise the rod 12 relatively to the ground.
The rods 12 are movable by the rod handler 10 while the rods 12 are supported in a substantially constant orientation by the rod receiving platform 20.
In some embodiments of the invention, the rod receiving platform 20 is rotatable about a platform axis 24, seen in Fig. 3, relatively to the platform attachment 22.
For example, the platform axis 24 is substantially vertical. This pivotal movement of the rod receiving platform 20 allows to reach rods 12 that are located further away from the arm 16 than would be possible if this pivotal movement was not allowed.
In other words, since the rod handler 10 is typically used around other machinery, this pivotal movement allows more flexibility in the positioning and use of the rod handler 10 as rods 12 being located further away from the arm 16 are then accessible.
Also, in some embodiments of the invention, the arm 16 is also pivotable in a substantially horizontal plane 19, seen in Fig. 3, relatively to the handler base 14.

DETAILED DESCRIPTION
Figs. 1 to 4 illustrate a rod handler 10 for handling a rod 12. The rod handler 10 includes a handler base 14. An arm 16 is mechanically coupled to the handler base 14. The arm 16 is pivotable in a substantially vertical plane 18 (better seen in Fig.
4) relatively to the handler base 14. The rod handler 10 also includes a rod receiving platform 20 for receiving the rod 12. A platform attachment 22 is operatively coupled to the arm 16 and to the rod receiving platform 20 for maintaining a substantially predetermined angular relationship between the rod receiving platform 20 and the handler base 14 when the arm 16 is pivoted in the substantially vertical plane 18. The rod receiving platform 20, in some embodiments of the invention, is removably attachable to the platform attachment 22.
Having a rod receiving platform 20 that is removably attachable to the platform attachment 22 allows to change the rod receiving platform 20 so that a suitable rod receiving platform 20 is used with rods 12 having different diameters. Since only a relatively small portion of the rod handler 10 is changed when the rods 12 used change diameter, it is relatively inexpensive to have a rod handler 10 that may handle rods 12 having diameters varying over a relatively wide range.
Therefore, there is no need to have a hydraulic clamp for clamping the rods 12, which are commonly used in prior art rod handlers, in the rod handler 10.
In some embodiments of the invention, the platform attachment 22 is operatively 5 coupled to the arm 16 and to the rod receiving platform 20 for maintaining the rod receiving platform 20 substantially horizontal when the arm 16 is pivoted in a substantially vertical plane 18, as seen in Fig. 3. In these embodiments of the invention, the rod 12 is then relatively easily supported in a stable manner onto the rod receiving platform 20 when the rod handler 10 is used to lower or to raise the rod 12 relatively to the ground.
The rods 12 are movable by the rod handler 10 while the rods 12 are supported in a substantially constant orientation by the rod receiving platform 20.
In some embodiments of the invention, the rod receiving platform 20 is rotatable about a platform axis 24, seen in Fig. 3, relatively to the platform attachment 22.
For example, the platform axis 24 is substantially vertical. This pivotal movement of the rod receiving platform 20 allows to reach rods 12 that are located further away from the arm 16 than would be possible if this pivotal movement was not allowed.
In other words, since the rod handler 10 is typically used around other machinery, this pivotal movement allows more flexibility in the positioning and use of the rod handler 10 as rods 12 being located further away from the arm 16 are then accessible.
Also, in some embodiments of the invention, the arm 16 is also pivotable in a substantially horizontal plane 19, seen in Fig. 3, relatively to the handler base 14.
This pivotal movement is better illustrated in Fig. 4. Therefore, the rod handler 10 may move the rods 12 to allow an intended user to move the rods 12 from a first location to a second location.
An example of a specific rod receiving platform 20 is described hereinbelow.
However, in alternative embodiments of the invention, any other suitable rod receiving platform 20 may be used.
Referring to Figs. 1 and 2, the rod receiving platform 20 includes a platform bottom wall 26 (seen in Fig. 2) for receiving the rod 12 thereonto and a platform peripheral wall 28 extending substantially upwardly from the platform bottom wall 26. The platform peripheral wall 28 defines an enclosure in which the rod 12 may be relatively stably supported. In other words, the platform peripheral wall 28 allows to move the rod 18 with reduced risks that the rod 18 would slip from the platform bottom wall 26.
In some embodiments of the invention, the platform peripheral wall 28 defines a substantially arc segment shaped wall first end section 30 for abutting the rod 12 thereonto. For example, and non-limitingly, the wall first end section 30 is located substantially distally relatively to the platform attachment 22. Since an intended user typically handles the rod 12 onto the rod handler 10 while located substantially opposed to the arm 16, this location of the wall first end section 30 allows to relatively easily stabilize the rod 12 by abutting the rod 12 against the wall first end section 30.
The platform peripheral wall 28 further defines a wall second end section 32 located substantially opposed to the wall first end section 30. Two wall lateral sections 34 and 35 extend between the wall first and second end sections 30 and 32. For example, the wall lateral sections 34 and 35 are substantially tapered toward each other in a direction leading substantially towards the wall first end section 30. This tapered configuration allows to relatively easily insert the rod 18 in the enclosure defined by the platform peripheral wall 28 and to relatively easily guide the rod 12 towards the wall first end section 30.
To improve the rod stabilizing properties of the wall first end section 30, in some embodiments of the invention, the wall first end section extends substantially upwardly further away from the platform bottom wall 16 than the wall lateral and second end sections 34, 35 and 32. Also, having wall lateral and second end sections 34, 35 and 32 that extend only over a relatively small distance upwardly from the platform bottom wall 26 allow to relatively easily insert the rod 12 in the enclosure defined by the platform peripheral wall 28.
The platform attachment 22 includes a platform attachment arm receiving portion 37 for receiving the arm 16. Also, in some embodiments of the invention, the platform attachment 22 includes an attachment plate 36 for attaching the rod receiving platform 20 thereto. For example, the rod attachment plate 36 is substantially horizontal and allows to relatively easily attach suitably shaped rod receiving platform 20 thereto. In some embodiments of the invention, a nut and a bolt are used to attach the rod receiving platform 20 to the attachment plate 22 by passing the nut and the bolt through suitably positioned and oriented apertures provided into the attachment plate 36 and the rod receiving platform 20.
The arm 16 includes an arm base 38 and a pair of substantially parallel and substantially elongated members 56 and 58. The substantially parallel elongated members 56 and 58 are each mechanically coupled to the platform attachment 22 and to the arm base 38 so as to remain substantially parallel relatively to each other when the arm 16 is pivoted in the substantially vertical plane 18.
In some embodiments of the invention, as better illustrated in Fig. 2, the arm base 38 includes an arm base first portion 40 and an arm base second portion 42.
The arm base first and second portions 40 and 42 are pivotably mounted to each other to allow the substantially horizontal pivotal movement of the arm 16 relatively to the handler base 14. The arm base first portion is 40, for example, substantially U-shaped and defines arm base legs 44 and an arm base connecting member 46 extending therebetween. The arm base legs 44 extend substantially upwardly and an arm base rod 48 extends substantially downwardly from the arm base connecting member 46.
The arm base second portion includes an arm base rod receiving portion 50 defining an arm base passageway 52 for receiving the arm base rod 48 thereinto.
Also, the arm base second portion 42 includes a substantially downwardly extending tongue 54, the tongue 54 being, for example, substantially plate-shaped.
The first elongated member 56 defines a first elongated member first end 60 and a substantially longitudinally opposed first elongated member second end 62.
Also, the second elongated member 58 defines a second elongated member first end 64 and a second elongated member second end 66 substantially longitudinally opposed to the second elongated member first end 64.
The first and second elongated members 56 and 58 each define a respective elongated member to arm base attachment location 68 pivotably attached to the arm base 38 and a respective elongated member to platform attachment location 72 pivotably attached to the platform attachment 22. Distances between the elongated member to base attachment locations 68 and the elongated member to platform attachment locations 72 are substantially similar for both substantially parallel elongated members. For example, and non-limitingly, the elongated member to arm base attachment locations 68 are located substantially adjacent the first and second elongated member first ends 60 and 62. Also, the elongated member to platform attachment locations 72 are located substantially adjacent second elongated members second ends 64 and 66.
This configuration of the first and second elongated members 56 and 58 allows to maintain a substantially predetermined orientation of the rod receiving platform 20.
In some embodiments of the invention, an actuator 80 is operatively coupled to the arm base 38 and to at least one of the first and second elongated members 56 and 58 for pivoting the first and second elongated members 56 and 58 relatively to the arm base 38. Therefore, the actuator 80 allows to pivot the arm 16 in the substantially vertical plane 18. For example, and non-limitingly, the actuator includes a hydraulic cylinder extending between the second elongated member 58 and the arm base 38. The hydraulic cylinder is secured to the second elongated member 58 at a location substantially intermediate the second elongated member first and second ends 64 and 662. Also, the hydraulic cylinder is secured to the arm base 38 at a location located substantially upwardly relatively to the locations at which the first and second elongated members 58 and 56 are secured to the arm base 38.
The handler base 14 includes a base first component 82 and a base second component 84. The base second component 84 is mounted to base first component 82 so as to be transitionally mobile relatively thereto. For example, this transitional motion allows to adjust the position of the arm 16 relatively to the handier base 14 to fine tune the adjustments of the position of the arm 16 to 5 facilitate the manipulation of the rods 12. To that effect, the base first component 82 includes a substantially elongated mounting member 86 supported substantially spaced apart from the ground, for example, by two posts 85. The base second component 84 includes a sleeve 90 mounted to the mounting member 86 so as to be longitudinally slidable relatively thereto. In some embodiments of the invention, 10 a second component lock 92 is provided for locking the slidable motion of the base first component 82 relatively to the base second component 84. For example, the second component lock 92 includes a second component lock aperture 94 and a second component lock bolt 96. The second component lock aperture 94 extends through the sleeve 90 and is threaded to allow threading the second component lock bolt 96 thereinto until the second component lock bolts 96 abut against the base first component 82, therefore preventing, at least in part, a substantially longitudinal movement of the base second component 84 relatively to the base first component 82.
In some embodiments of the invention, the arm 16 is movably mountable to the handler base 14. To that effect, the base second component 84 includes a tongue receiving passageway 88 for receiving the tongue 54. The tongue receiving passageway 88 extends substantially vertically and receives slidably the tongue 54 thereinto. Therefore, attachment of the arm 16 to the handier base 14 and removal of the arm 16 from the base 14 is relatively easily performed in a relatively simple movement.
An example of a specific rod receiving platform 20 is described hereinbelow.
However, in alternative embodiments of the invention, any other suitable rod receiving platform 20 may be used.
Referring to Figs. 1 and 2, the rod receiving platform 20 includes a platform bottom wall 26 (seen in Fig. 2) for receiving the rod 12 thereonto and a platform peripheral wall 28 extending substantially upwardly from the platform bottom wall 26. The platform peripheral wall 28 defines an enclosure in which the rod 12 may be relatively stably supported. In other words, the platform peripheral wall 28 allows to move the rod 18 with reduced risks that the rod 18 would slip from the platform bottom wall 26.
In some embodiments of the invention, the platform peripheral wall 28 defines a substantially arc segment shaped wall first end section 30 for abutting the rod 12 thereonto. For example, and non-limitingly, the wall first end section 30 is located substantially distally relatively to the platform attachment 22. Since an intended user typically handles the rod 12 onto the rod handler 10 while located substantially opposed to the arm 16, this location of the wall first end section 30 allows to relatively easily stabilize the rod 12 by abutting the rod 12 against the wall first end section 30.
The platform peripheral wall 28 further defines a wall second end section 32 located substantially opposed to the wall first end section 30. Two wall lateral sections 34 and 35 extend between the wall first and second end sections 30 and 32. For example, the wall lateral sections 34 and 35 are substantially tapered toward each other in a direction leading substantially towards the wall first end section 30. This tapered configuration allows to relatively easily insert the rod 18 in the enclosure defined by the platform peripheral wall 28 and to relatively easily guide the rod 12 towards the wall first end section 30.
To improve the rod stabilizing properties of the wall first end section 30, in some embodiments of the invention, the wall first end section extends substantially upwardly further away from the platform bottom wall 16 than the wall lateral and second end sections 34, 35 and 32. Also, having wall lateral and second end sections 34, 35 and 32 that extend only over a relatively small distance upwardly from the platform bottom wall 26 allow to relatively easily insert the rod 12 in the enclosure defined by the platform peripheral wall 28.
The platform attachment 22 includes a platform attachment arm receiving portion 37 for receiving the arm 16. Also, in some embodiments of the invention, the platform attachment 22 includes an attachment plate 36 for attaching the rod receiving platform 20 thereto. For example, the rod attachment plate 36 is substantially horizontal and allows to relatively easily attach suitably shaped rod receiving platform 20 thereto. In some embodiments of the invention, a nut and a bolt are used to attach the rod receiving platform 20 to the attachment plate 22 by passing the nut and the bolt through suitably positioned and oriented apertures provided into the attachment plate 36 and the rod receiving platform 20.
The arm 16 includes an arm base 38 and a pair of substantially parallel and substantially elongated members 56 and 58. The substantially parallel elongated members 56 and 58 are each mechanically coupled to the platform attachment 22 and to the arm base 38 so as to remain substantially parallel relatively to each other when the arm 16 is pivoted in the substantially vertical plane 18.
In some embodiments of the invention, as better illustrated in Fig. 2, the arm base 38 includes an arm base first portion 40 and an arm base second portion 42.
The arm base first and second portions 40 and 42 are pivotably mounted to each other to allow the substantially horizontal pivotal movement of the arm 16 relatively to the handler base 14. The arm base first portion is 40, for example, substantially U-shaped and defines arm base legs 44 and an arm base connecting member 46 extending therebetween. The arm base legs 44 extend substantially upwardly and an arm base rod 48 extends substantially downwardly from the arm base connecting member 46.
The arm base second portion includes an arm base rod receiving portion 50 defining an arm base passageway 52 for receiving the arm base rod 48 thereinto.
Also, the arm base second portion 42 includes a substantially downwardly extending tongue 54, the tongue 54 being, for example, substantially plate-shaped.
The first elongated member 56 defines a first elongated member first end 60 and a substantially longitudinally opposed first elongated member second end 62.
Also, the second elongated member 58 defines a second elongated member first end 64 and a second elongated member second end 66 substantially longitudinally opposed to the second elongated member first end 64.
The first and second elongated members 56 and 58 each define a respective elongated member to arm base attachment location 68 pivotably attached to the arm base 38 and a respective elongated member to platform attachment location 72 pivotably attached to the platform attachment 22. Distances between the elongated member to base attachment locations 68 and the elongated member to platform attachment locations 72 are substantially similar for both substantially parallel elongated members. For example, and non-limitingly, the elongated member to arm base attachment locations 68 are located substantially adjacent the first and second elongated member first ends 60 and 62. Also, the elongated member to platform attachment locations 72 are located substantially adjacent second elongated members second ends 64 and 66.
This configuration of the first and second elongated members 56 and 58 allows to maintain a substantially predetermined orientation of the rod receiving platform 20.
In some embodiments of the invention, an actuator 80 is operatively coupled to the arm base 38 and to at least one of the first and second elongated members 56 and 58 for pivoting the first and second elongated members 56 and 58 relatively to the arm base 38. Therefore, the actuator 80 allows to pivot the arm 16 in the substantially vertical plane 18. For example, and non-limitingly, the actuator includes a hydraulic cylinder extending between the second elongated member 58 and the arm base 38. The hydraulic cylinder is secured to the second elongated member 58 at a location substantially intermediate the second elongated member first and second ends 64 and 662. Also, the hydraulic cylinder is secured to the arm base 38 at a location located substantially upwardly relatively to the locations at which the first and second elongated members 58 and 56 are secured to the arm base 38.
The handler base 14 includes a base first component 82 and a base second component 84. The base second component 84 is mounted to base first component 82 so as to be transitionally mobile relatively thereto. For example, this transitional motion allows to adjust the position of the arm 16 relatively to the handier base 14 to fine tune the adjustments of the position of the arm 16 to 5 facilitate the manipulation of the rods 12. To that effect, the base first component 82 includes a substantially elongated mounting member 86 supported substantially spaced apart from the ground, for example, by two posts 85. The base second component 84 includes a sleeve 90 mounted to the mounting member 86 so as to be longitudinally slidable relatively thereto. In some embodiments of the invention, 10 a second component lock 92 is provided for locking the slidable motion of the base first component 82 relatively to the base second component 84. For example, the second component lock 92 includes a second component lock aperture 94 and a second component lock bolt 96. The second component lock aperture 94 extends through the sleeve 90 and is threaded to allow threading the second component lock bolt 96 thereinto until the second component lock bolts 96 abut against the base first component 82, therefore preventing, at least in part, a substantially longitudinal movement of the base second component 84 relatively to the base first component 82.
In some embodiments of the invention, the arm 16 is movably mountable to the handler base 14. To that effect, the base second component 84 includes a tongue receiving passageway 88 for receiving the tongue 54. The tongue receiving passageway 88 extends substantially vertically and receives slidably the tongue 54 thereinto. Therefore, attachment of the arm 16 to the handier base 14 and removal of the arm 16 from the base 14 is relatively easily performed in a relatively simple movement.
In some embodiments of the invention, a tongue lock 98 is provided for locking the tongue 55 inside the tongue receiving passageway 98. For example, the tongue lock includes a tongue lock aperture 100 extending through the base second component 84 into the tongue receiving passageway 88. The tongue lock aperture is threaded and a tongue lock bolt 102 is usable to thread into the tongue lock aperture until it abuts against the tongue 54 thereby locking the tongue 54 inside the tongue receiving passageway. It should be noted that this relatively simple tongue lock 98 is relatively efficient as it is relatively simple, relatively easily operated and typically does not require that relatively large forces be exerted unto the tongue 54 as the tongue 54 is mainly maintained inside the tongue receiving passageway 88 by the weight of the arm 16.
In some embodiments of the invention, a wear plate 104 is positionable within the enclosure defined by the plafform peripheral wall 28 so as to abut against the platform bottom wall 16. The wear plate 104 is typically removably attachable to the platform bottom wall 26 and may be changed when repeated shocks of the rods 12 against the wear plate 104 have worn the wear plate 104 to a relatively small thickness that is too small to protect the platform bottom wall 26 against shocks.
In use, the arm 16 is raised and located substantially adjacent a rod 12. The rod 12 is then lowered unto the rod receiving platform 20. An intended user, for example using his hands, maintains the rod 12 substantially vertical and rotates the arm 16 in the substantially horizontal plane 19. Then, when the rod 12 has been moved away from the location from which it has been picked up, the rod 12 is lowered, for example using the actuator 80 to pivot the arm 16 in the substantially vertical plane 18. Then, the rod 12 is located substantially adjacent the ground and may be relatively easily lifted over the wall of the rod receiving platform 20, and disposed on the ground. To move a rod 12 from the ground to a destination location, these steps are reversed.
Although the present invention has been described hereinabove by way of preferred embodiments thereof, it can be modified without departing from the spirit, scope and nature of the subject invention, as defined in the appended claims.
