Description

Technical Field

[0001] This utility model relates to the field of hydraulic support technology, specifically to a mining hydraulic rod with a positioning structure. Background Technology

[0002] Existing mining hydraulic rods have shortcomings. In terms of positioning, the guide structure only provides unidirectional constraint and lacks radial multi-dimensional limiting. High-frequency vibration can easily cause the piston rod to sway left and right or move up and down. Furthermore, there is a lack of dust and impurity treatment and no cleaning components. Dust and slag can easily accumulate, causing jamming and wear. Replacing the cleaning components requires disassembling multiple related structures, resulting in long downtime maintenance.

[0003] Therefore, this utility model provides a mining hydraulic rod with a positioning structure. The connecting plate is rigidly connected to the hydraulic cylinder to stabilize the motion reference. The positioning uses a circumferential array of limiting guide rods to form an enclosed guide, which helps to reduce radial runout when carrying loads or in a vibrating environment. When handling impurities, the brush is distributed in a spiral curve, which is conducive to multi-directional cleaning and automatic impurity removal from the conical inner wall. The brush sleeve is detachable by thread, simplifying the replacement process and making it suitable for complex mining conditions. Utility Model Content

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows: a mining hydraulic rod with a positioning structure, comprising: a piston rod, one end of which is threadedly connected to a connector; a guide plate is fixedly connected to the outer wall of the connector by an internal hexagonal bolt; a limit guide rod is fixedly connected to the outer wall of the guide plate; a connecting plate is slidably connected to the outer wall of the limit guide rod; a support rod is fixedly connected to the outer wall of the connecting plate; a storage sleeve is fixedly connected to the outer wall of the support rod away from the guide plate; a threaded groove is formed on the inner wall of the storage sleeve; a brush sleeve is threadedly connected to the inner wall of the threaded groove; a mounting plate is fixedly connected to the outer wall of one end of the guide plate; a mounting hole is formed on the outer wall of the mounting plate; the limit guide rod is arranged in a circumferential array along the outer wall of the guide plate; the brushes inside the brush sleeve are arranged in a threaded curve array along its inner wall; and the brushes inside the brush sleeve... The outer wall of the brush is slidably connected to the outer wall of the piston rod. The inner wall of the brush sleeve is tapered, with a lower front and a higher back, which facilitates the automatic discharge of dust. In use, this mining hydraulic rod with a positioning structure is designed to adapt to mining scenarios with high vibration, many impurities, and heavy loads. First, a stable working foundation is built through multi-dimensional installation and fixing. The outer wall of one end of the piston rod is threaded and connected to the connector to ensure coaxiality. The connector is then fixed to the guide plate with hexagonal bolts to avoid bolt jamming caused by mining dust. The mounting plate at one end of the guide plate has mounting holes arranged linearly in the length and width directions. This allows it to adapt to different external mining equipment interfaces and disperse vibration stress through multi-point bolt fixing. At the same time, the connecting plate is fastened to the outer wall of the hydraulic cylinder with bolts to ensure that the hydraulic cylinder and hydraulic rod components form a rigid linkage, providing a reference without relative displacement for subsequent movements. The outer wall of the connecting plate is fixedly connected to the outer wall of the hydraulic cylinder with bolts.

[0005] Preferably, the support rods are arranged in a circumferential array along the outer wall of the connecting plate. During the positioning process, the device relies on the circumferential array structure and sliding cooperation to achieve stable extension and retraction of the piston rod. The limiting guide rods on the outer wall of the guide plate are arranged in a circumferential array, forming a surrounding guide for the slidingly connected connecting plate from multiple radial angles. When the hydraulic cylinder drives the connecting plate to move, the limiting guide rods can limit its radial displacement, which helps to prevent the piston rod from swaying left and right or moving up and down due to mining vibration. The support rods on the outer wall of the connecting plate are also arranged in a circumferential array and connect to the storage sleeve. While evenly distributing the force, they drive the storage sleeve and the connecting plate to move synchronously. Combined with the fit between the brush sleeve inside the storage sleeve and the piston rod, a motion chain is formed from the hydraulic cylinder, passing through the connecting plate, the support rods and the storage sleeve, and finally acting on the piston rod. Even under heavy load conditions, the limiting guide rods and support rods can help maintain stable guidance and positioning.

[0006] Preferably, the mounting holes on the outer wall of the mounting plate are arranged in a linear array along the length and width of the mounting plate, facilitating connection with external equipment. Addressing the issue of impurities in the mining environment, the device employs a special structural design to achieve automatic cleaning and convenient maintenance, contributing to the long-term stability of the positioning function. The brushes inside the brush sleeve are arranged in a spiral array along the inner wall, which, compared to a traditional linear array, allows for a longer contact path and more varied angles, enabling more surface dust and slag to be swept away during piston rod extension and retraction, reducing cleaning dead zones. Its inner wall is conical, lower at the front and higher at the back, allowing gravity and the thrust of the piston rod to guide the swept impurities outwards automatically, preventing impurity accumulation and potential piston rod jamming or wear. Simultaneously, the brush sleeve is detachably connected to the storage sleeve via a threaded groove. When the brushes wear out, there is no need to disassemble the support rod or storage sleeve; simply rotating the brushes allows for easy removal and replacement or cleaning, reducing downtime for mining equipment maintenance and ensuring long-term stable operation of the entire device.

[0007] The beneficial effects of this utility model are as follows:

[0008] 1. This utility model uses a connecting plate that is rigidly connected to the hydraulic cylinder and a limiting guide rail rod that is arranged in a circular array along the outer wall of the guide rail plate. The rigid connection between the connecting plate and the hydraulic cylinder can stabilize the motion reference. The circular array of limiting guide rail rods can form a radial encircling guide, replacing the traditional single-direction guide structure. This helps to reduce the left-right swaying and up-down movement of the piston rod under mining vibration or heavy load conditions.

[0009] 2. This utility model features a brush with a spirally distributed inner wall, a brush sleeve with a tapered inner wall that is lower at the front and higher at the back, and a threaded connection between the brush sleeve and the storage sleeve. The spirally distributed brush can clean dust and slag from the piston rod surface from multiple directions, and the tapered inner wall can automatically guide impurities out, avoiding jamming and wear caused by accumulation. The threaded connection allows the brush sleeve to be easily replaced without disassembling the support rod or other related structures. Attached Figure Description

The outer wall of the mounting plate 9 has mounting holes. The limiting guide rod 4 is distributed in a circumferential array along the outer wall of the guide plate 3.

The inner wall of the brush sleeve 8 is tapered with a lower front and a higher back to facilitate the automatic discharge of dust. The outer wall of the connecting plate 5 is fixedly connected to the outer wall of the hydraulic cylinder by bolts.

[0018] The support rods 6 are arranged in a circular array along the outer wall of the connecting plate 5, and the mounting holes on the outer wall of the mounting plate 9 are arranged in a linear array along the length and width of the mounting plate 9, which facilitates connection with external equipment.

[0019] Working principle:

[0020] In use, this mining hydraulic rod with a positioning structure is designed to adapt to mining scenarios characterized by high vibration, numerous impurities, and heavy loads. First, a stable working foundation is constructed through multi-dimensional installation and fixation. One end of the piston rod 1 is threaded to the connector 2, ensuring coaxiality. The connector 2 is then fixed to the guide plate 3 with hexagonal bolts to prevent bolt jamming caused by mining dust. The mounting plate 9 at one end of the guide plate 3 has mounting holes arranged linearly along its length and width, which can accommodate different external mining equipment interfaces and disperse vibration stress through multi-point bolt fixation. At the same time, the connecting plate 5 is fastened to the outer wall of the hydraulic cylinder with bolts, ensuring that the hydraulic cylinder and hydraulic rod components form a rigid linkage, providing a reference without relative displacement for subsequent movements.

[0021] In the positioning stage, the device relies on a circumferential array structure and sliding cooperation to achieve stable extension and retraction of the piston rod 1. The limiting guide rods 4 on the outer wall of the guide plate 3 are distributed in a circumferential array, forming a surrounding guide for the slidingly connected connecting plate 5 from multiple radial angles. When the hydraulic cylinder drives the connecting plate 5 to move, the limiting guide rods 4 can limit its radial displacement, which helps to prevent the piston rod 1 from swaying left and right or moving up and down due to mining vibration. The support rods 6 on the outer wall of the connecting plate 5, which are also in a circumferential array, connect to the placement sleeve 7. While evenly distributing the force, they drive the placement sleeve 7 to move synchronously with the connecting plate 5. Combined with the fit between the brush sleeve 8 inside the placement sleeve 7 and the piston rod 1, a motion chain is formed from the hydraulic cylinder, passing through the connecting plate 5, the support rod 6 and the placement sleeve 7, and finally acting on the piston rod 1. Even under heavy load conditions, the limiting guide rods 4 and the support rods 6 can help maintain stable guidance and positioning.

[0022] To address the issue of impurities in the mining environment, the device employs a special structural design to achieve automatic cleaning and convenient maintenance. This facilitates the long-term stability of the positioning function. The brushes inside the brush sleeve 8 are arranged in a spiral array along the inner wall. Compared to traditional linear arrays, this allows for a longer contact path and more varied angles, enabling more surface dust and slag to be swept away during the extension and retraction of the piston rod 1, reducing cleaning dead zones. The inner wall is conical, with a lower front and higher back, which, with the help of gravity and the thrust of the piston rod 1, guides the swept impurities to be automatically discharged outwards, preventing impurity accumulation and avoiding jamming or wear of the piston rod 1. Simultaneously, the brush sleeve 8 is detachably connected to the storage sleeve 7 via a threaded groove. When the brushes wear out, there is no need to disassemble the support rod 6 or the storage sleeve 7; they can be removed and replaced or cleaned simply by rotating them. This helps reduce downtime for mining equipment maintenance and ensures the long-term stable operation of the entire device.
