Description
[0001] REMOVABLE AND SLIDING ROCK SCALING PLATFORM TECHNICAL FIELD
[0002] The present invention falls within the technical field of specialized equipment for rock scaling in the mining sector. Specifically, the proposed invention refers to a removable platform for rock scaling with a longitudinal path through a hydraulic cylinder and with a removable chisel.
[0003] STATE OF THE ART
[0004] The prior art includes patent application CN105822225A, published on August 3, 2016, which relates to a rock drilling structure with one boom and two drill heads. The structure includes a long carriage for sliding a drill boom via a connecting mechanism. This connecting mechanism includes a forward-and-backward oscillation mechanism (7) connected to the drill boom. This prior art mentions that it can be broadly applied to single- or double-boom jumbo drills, pneumatic or track-type, including multi-boom models, or integrated drilling and loading machines.
[0005] Another known patent document is US3712385A, published on January 23, 1973, relating to a mobile drilling platform with an adjustable boom, in which the platform allows the horizontal sliding of a drilling head and the platform with the drilling head is arranged on a carrier arm.
[0006] However, the prior art lacks the ability to slide along at least one beam of the arm itself, and the fixed anchor to the arm is of a minimal area on the underside of the beam, solely for the attachment of a hydraulic cylinder. Additionally, the prior art does not have a removable rock scaling platform with longitudinal movement of the drill head or chisel, where the chisel is removable by unlocking it. Furthermore, the prior art does not utilize the longitudinal space occupied by the hydraulic cylinder to position the base of the rock scaling device or hammer above or below it, thus maintaining a compact rock scaling platform.
[0007] DESCRIPTION OF THE INVENTION
[0008] To solve the aforementioned problems, the present invention has been devised, which relates to a removable rock scaling platform sliding on at least one beam of an articulated arm (boom), characterized in that it comprises a first connection element fixed to the beam and a second connection element sliding on the at least one beam, wherein a hydraulic cylinder is connected between the first fixed connection element and the second sliding connection element, a rock scaling device which includes a base and a chisel, wherein the base of the rock scaling device is coupled to the second sliding connection element and wherein the chisel is removable.
[0009] The present invention overcomes the limitations of the prior art by providing a removable rock scaling platform that offers a number of significant advantages:
[0010] The ability to slide the platform along a beam of the articulated arm allows for greater flexibility in rock scaling operations, adapting to various configurations and reaching hard-to-access areas.
[0011] The compact design of the second connecting element, which integrates both the hydraulic cylinder coupling and the rock scaling device base, maximizes the use of available space on the platform. The modular design of the bolt-adjustable platform facilitates the disassembly and replacement of components, reducing maintenance times and increasing equipment availability.
[0012] BRIEF DESCRIPTION OF THE FIGURES
[0013] In order to facilitate the understanding of the characteristics of the invention, a set of drawings is included with this descriptive report in which, for illustrative and non-limiting purposes, the following has been represented:

[0022] 3: Vibration damping element
[0023] 4: Hydraulic cylinder
[0024] 5: Second sliding connection element 6: Rock scaling device

[0027] 9: Motherboard
[0028] PREFERRED EMBODIMENTS OF THE INVENTION
[0029] In a preferred embodiment of the invention, the second sliding connecting element (5) has a pair of sliding rails (2) with a “v” profile, and a pair of vibration damping elements (3), each arranged on the inner part of each sliding rail (2). These damping elements can be polymer holders.
[0030] In another preferred embodiment of the invention, the second sliding connection element (5) has a base plate for coupling the hydraulic cylinder on one side of the base plate and coupling the base of the rock scaling device on the opposite side of the base plate, which allows for optimization of the space used.
[0031] In another preferred embodiment of the invention, a protective housing (7) surrounds the base of the rock scaling device (6) and is fixed to the second sliding connection element (5).
[0032] In another preferred embodiment of the invention, a side area of the protective housing (7) has a hole in which a release element is housed to release the chisel.
[0033] In another preferred embodiment of the invention, a plug is disposed in the chisel inlet hole for cases where the chisel is removed, to keep the chisel inlet hole clean.
[0034] In another preferred embodiment, the rock scaling device may internally include a retractable chisel mechanism. It should be noted that for the purposes of the present invention, the term “removable chisel” is broad and encompasses the ability to retract or conceal the chisel.
[0035] Additional advantages of the proposed invention:
[0036] The proposed invention provides a rock scaling platform that incorporates a highly space-efficient design, thanks to the coupling system between the hydraulic cylinder, the base of the rock scaling device, and the second sliding connecting element. The compact and optimized arrangement of these elements, with one above or below the other, reduces the space required for operation, facilitating maneuverability and improving the overall efficiency of the rock scaling platform.
[0037] Furthermore, the platform's second sliding connection element is designed with a pair of V-shaped sliding rails and vibration damping elements. This facilitates smooth and controlled sliding of the system and minimizes the impact of vibrations generated during operation, increasing the stability and durability of the proposed invention and protecting both the rock scaling device and associated equipment.
[0038] The invention includes a protective housing that surrounds the base of the rock scaling device, providing an additional layer of safety and protection against adverse working conditions. This housing not only protects the device's sensitive components but is also designed to be robust, increasing the invention's service life in demanding environments such as mining or construction.
[0039] The inclusion of a release mechanism with a side hole in the protective housing facilitates unlocking and removal of the chisel. This design allows for quick and easy maintenance without the need for complex tools or removing the protective housing, improving operational efficiency and reducing downtime. Valves (not shown) are provided for admitting and discharging hydraulic fluid from the hydraulic cylinder and hydraulic motor of the rock scaling device, if the latter is hydraulically driven. These valves may be mounted on a valve bank (not shown) within reach of the vehicle operator and are connected via hydraulic lines (not shown) to the proposed rock scaling platform.
[0040] The rock scaling device, which can be a hammer like the polisher, is hydraulically powered and can therefore be connected to the vehicle's hydraulic system. Alternatively, the rock scaling device can be powered by other suitable or available means, such as compressed air or electricity.
[0041] In another preferred embodiment, the proposed invention can be installed on the simple or telescopic advance beams of Jumbo front drilling vehicles, with a system hydraulically controlled from the cab with a selector that activates or deactivates it.
