Description

Technical Field

[0001] This invention belongs to the field of mining equipment technology, and specifically relates to a landslide-resistant mining equipment. Background Technology

[0002] During operation, mining equipment often encounters various geological conditions, such as slopes. In such cases, the equipment is prone to displacement. While some anti-slope fixing structures exist, they are typically driven vertically into the surface of the mountain.

[0057] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0058] refer to Figures 1-13 The present invention provides a landslide-resistant mining equipment, including a mining vehicle and a support device installed at the bottom of the mining vehicle;

[0059] The support device includes a mounting frame 1, a vertical fixing component 2, a triangular tilt fixing component 3, a lifting component 4, and a rotary drive component 5. The lifting component 4 and the rotary drive component 5 are both mounted on the mounting frame 1. The vertical fixing component 2 is connected to the lifting component 4, and the triangular tilt fixing component 3 is connected to both the rotary drive component 5 and the lifting component 4.

[0060] Mounting frame 1 includes mounting plate 11 and support plate 12; mounting plate 11 is fixedly installed on the bottom of mining vehicle, and support plate 12 is located directly below mounting plate 11. Mounting plate 11 and support plate 12 are connected by connecting column.

[0061] The vertical fixing assembly 2 includes a vertical drilling rod 21 and a fixed center seat 22. The triangular inclined fixing assembly 3 includes an inclined drilling rod 31 and an inclined guide seat 32. The fixed center seat 22 is a hollow cylinder. The fixed center seat 22 is vertically and fixedly installed on the upper surface of the support plate 12. The vertical drilling rod 21 is rotatably connected inside the fixed center seat 22 and passes through the support plate 12. The lifting assembly 4 is connected to the vertical drilling rod 21. The triangular inclined fixing assembly 3 is provided in three sets. The three sets of triangular inclined fixing assemblies 3 are arranged in a ring around the axis of the vertical drilling rod 21 and are inclined outward. The inclined guide seat 32 is a hollow cylinder. The inclined guide seat 32 is inclinedly set on the upper surface of the support plate 12. The inclined drilling rod 31 is rotatably connected inside the inclined guide seat 32. The inclined drilling rod 31 is connected to the rotary drive assembly 5 and the lifting assembly 4.

[0062] Mining trucks are used for mining in mines. Support devices are used to support the mining trucks on the inclined mine slopes, so that the mining trucks remain stable during operation and do not cause slippage or landslides.

[0063] The outer wall of the vertical drilling rod 21 is provided with a first external thread, and the inner wall of the fixed center seat 22 is provided with a first internal thread that meshes with the vertical drilling rod 21; the outer wall of the inclined drilling rod 31 is provided with a second external thread, and the inner wall of the inclined guide seat 32 is provided with a second internal thread that meshes with the inclined drilling rod 31.

[0064] The lifting assembly 4 is connected to the vertical drilling rod 21 and the inclined drilling rod 31 respectively. The lifting assembly 4 is used to keep the vertical drilling rod 21 and the inclined drilling rod 31 moving synchronously in the vertical direction.

[0065] The rotary drive assembly 5 is connected to the vertical drill rod 21 and the inclined drill rod 31 respectively. The rotary drive assembly 5 is used to drive the vertical drill rod 21 and the inclined drill rod 31 to rotate around their own axes respectively.

[0066] Before mining operations are carried out, the mining vehicle is driven to the designated work area. The drive unit on the mining vehicle drives the support device to descend to the working position, and the support plate 12 in the support device is in contact with the surface of the mine slope.

[0067] The rotary drive assembly 5 controls the vertical drilling rod 21 in the vertical fixing assembly 2 to rotate around its own axis. The fixed center seat 22 provides guidance for the vertical drilling rod 21 to drill into the ground, so that the vertical drilling rod 21 can be smoothly inserted into the soil layer in a direction perpendicular to the slope. The vertical drilling rod 21 and the fixed center seat 22 cooperate to firmly drive the bottom end of the vertical drilling rod 21 into the soil layer. The lifting assembly 4 controls the vertical fixing assembly 2 and the triangular tilting fixing assembly 3 to descend synchronously.

[0068] The rotary drive assembly 5 also controls the rotation of the inclined drilling rod 31 in the triangular inclined fixing assembly 3. During the rotation of the inclined drilling rod 31, it is gradually driven into the soil along its inclined direction. The three inclined drilling rods 31 expand outward at intervals of 120 degrees, firmly inserting the equipment into the soil, so that it can still achieve a good fixing effect on the slope with a large inclination angle.

[0069] The vertical drilling rod 21 and the inclined drilling rod 31 provide reinforcement and triangular support, firmly anchoring the mining truck to the slope, thus improving safety and preventing landslides and slippage during mining operations.

[0070] The downward pressure of the support plate 12 on the slope surface increases the friction between the support device and the slope surface. The support plate 12 can increase the contact area between the support device and the slope surface, thereby increasing the stability of the mining vehicle during operation and improving the operation effect.

[0071] The lifting assembly 4 includes a linear limiting rod 41, a lifting frame 42, and a downward transmission mechanism 43;

[0072] A linear limiting rod 41 is vertically and movable up and down on the mounting plate 11; a lifting frame 42 is located between the mounting plate 11 and the support plate 12, the lower end of the linear limiting rod 41 is fixedly connected to the top end of the lifting frame 42, and the rotary drive assembly 5 is installed on the lifting frame 42.

[0073] The downward transmission mechanism 43 is located between the lifting frame 42 and the support plate 12. The lifting frame 42 is connected to the downward transmission mechanism 43, and the downward transmission mechanism 43 is connected to the vertical drilling rod 21 and the inclined drilling rod 31 respectively.

[0074] The lifting frame 42 is driven to rise and fall inside the mounting frame 1 by the linear limiting rod 41. When the lifting frame 42 rises and falls, it drives the vertical fixing component 2 and the triangular inclined fixing component 3 connected to it to descend synchronously, so that the vertical drilling rod 21 and the inclined drilling rod 31 descend to the predetermined position to achieve the drilling and fixing effect. The downward transmission mechanism 43 drives the vertical drilling rod 21 and the inclined drilling rod 31 to descend synchronously, providing conditions for the rotary drive component 5 to drive the vertical drilling rod 21 and the inclined drilling rod 31 synchronously.

[0075] The downward transmission mechanism 43 includes a triangular transmission frame 431, a limiting sliding plate 432, a sliding seat 433, and a horizontal limiting block 434;

[0076] The triangular transmission frame 431 is fixedly connected to the lifting frame 42; the limiting sliding plate 432 is U-shaped and has three parts, and the three limiting sliding plates 432 are respectively located at the three ends of the triangular transmission frame 431; there are three sliding seats 433, and the upper end of the inclined drilling rod 31 is rotatably connected to the sliding seat 433. The inclination angle of the sliding seat 433 is perpendicular to the inclination angle of the inclined drilling rod 31. Horizontally set horizontal limiting blocks 434 are fixed on both sides of the sliding seat 433; the inner side wall of the limiting sliding plate 432 is provided with a horizontal limiting groove, and the horizontal limiting block 434 is slidably connected in the horizontal limiting groove.

[0077] When the downward transmission mechanism 43 is working, the downward movement of the lifting frame 42 drives the rotary drive component 5 to move synchronously. When the rotary drive component 5 moves downward, it drives the vertical drilling rod 21 connected to it to move synchronously downward. At the same time, the lifting frame 42 drives the triangular transmission frame 431 fixed to it to move synchronously downward. When the triangular transmission frame 431 moves downward, it drives the inclined drilling rod 31 connected to it to move downward. While the inclined drilling rod 31 moves downward, it moves horizontally away from the vertical drilling rod 21. The downward transmission mechanism 43 is used to ensure that the inclined drilling rod 31 and the vertical drilling rod 21 remain synchronized when they move downward.

[0078] When the triangular transmission frame 431 descends, it drives the three limiting sliding plates 432 fixedly connected to its end to move synchronously. When the limiting sliding plates 432 move, they drive the sliding seats 433 slidably mounted on the limiting sliding plates 432 to descend synchronously. When the sliding seats 433 descend, they achieve horizontal displacement relative to the triangular transmission frame 431 through the horizontal limiting block 434. The horizontal limiting groove on the limiting sliding plate 432 is used to guide and limit the displacement of the sliding seats 433.

[0079] The rotary drive assembly 5 includes a rotary driver 51, a rotating shaft 52, and a rotary transmission mechanism 53;

[0080] The rotary drive 51 is vertically mounted on the lifting frame 42, with its output end pointing vertically downwards. The top end of the rotating shaft 52 is fixedly connected to the output end of the rotary drive 51, and the bottom end of the rotating shaft 52 is fixedly connected to the top end of the vertical drilling rod 21. The rotary transmission mechanism 53 is mounted on the fixed center seat 22, and is connected to the rotating shaft 52. The rotary transmission mechanism 53 is also connected to the three inclined drilling rods 31.

[0081] The rotary driver 51 drives the rotating shaft 52 to rotate. When the rotating shaft 52 rotates, it drives the vertical drilling rod 21 connected to it to rotate, realizing the function of fixing the vertical drilling rod 21 in the forward drilling direction. At the same time, the rotating shaft 52 drives the rotary transmission mechanism 53 connected to it to move. The rotary transmission mechanism 53 drives the inclined drilling rod 31 to rotate through gear transmission, realizing the function of the three inclined drilling rods 31 drilling laterally.

[0082] The rotary transmission mechanism 53 includes a support sleeve 531, a rotary transmission component 532, and a gear transmission component 533.

[0083] The support sleeve 531 is fixedly installed on the upper surface of the support plate 12. The outer side of the support sleeve 531 is rotatably connected to the gear transmission component 533. The rotary transmission component 532 is connected to the rotating shaft 52. The rotary transmission component 532 is connected to the gear transmission component 533. The gear transmission component 533 is connected to the inclined drilling rod 31.

[0084] The rotary transmission component 532 includes a horizontal drive disk 5321, a rotary transmission disk 5322, and a telescopic rod 5323.

[0085] The horizontal drive disk 5321 is horizontally fixedly mounted on the rotating shaft 52; the rotary transmission disk 5322 is rotatably mounted on the outer wall of the fixed center seat 22 via bearings, the diameter of the rotary transmission disk 5322 gradually increases from top to bottom, and the inclination angle of the outer wall of the rotary transmission disk 5322 is consistent with the inclination angle of the inclined drilling rod 31; the telescopic rod 5323 is vertically arranged between the horizontal drive disk 5321 and the rotary transmission disk 5322, the top end of the telescopic rod 5323 is fixedly connected to the bottom end of the horizontal drive disk 5321, and the bottom end of the telescopic rod 5323 is fixedly connected to the top end of the rotary transmission disk 5322.

[0086] The gear transmission component 533 includes a drive ring tooth 5331, a rotating seat 5332, and a transmission gear 5333.

[0087] The drive ring gear 5331 is fixedly arranged in an annular shape on the inclined surface of the outer wall of the rotating transmission disk 5322; the rotating seat 5332 is fixedly arranged in an inclined shape on the outer side of the inclined drilling rod 31; the transmission gear 5333 is sleeved on the outer wall of the rotating seat 5332, the transmission gear 5333 is fixedly connected to the rotating seat 5332, and the transmission gear 5333 meshes with the drive ring gear 5331.

[0088] The support sleeve 531 is installed on the support plate 12 to support the gear transmission component 533 and ensure the horizontal rotation of the gear transmission component 533. When the rotary transmission mechanism 53 is working, the rotary transmission component 532 rotates under the drive of the rotating shaft 52. The rotary transmission component 532 drives the gear transmission component 533 to rotate synchronously, thereby driving the inclined drilling rod 31 to rotate.

[0089] The horizontal drive disk 5321 is fixedly connected to the rotating shaft 52. When the rotating shaft 52 rotates, it drives the horizontal drive disk 5321, which is fixedly connected to it, to rotate. The telescopic rod 5323 drives the rotating transmission disk 5322 to rotate synchronously with the horizontal drive disk 5321. In turn, the rotating transmission disk 5322 drives the gear transmission component 533 to achieve a rotational drive effect. The telescopic rod 5323 can still maintain its rotational transmission function when the distance between the horizontal drive disk 5321 and the rotating transmission disk 5322 changes.

[0090] When the rotary transmission disk 5322 rotates, it drives the drive ring gear 5331 installed on its outer side wall to rotate synchronously. The drive ring gear 5331 drives the transmission gear 5333 meshing with it to rotate, which in turn drives the rotating seat 5332 fixedly connected to the transmission gear 5333 to rotate synchronously, thus realizing the function of pressing the inclined drilling rod 31 into the ground.

[0091] The length of the meshing surface of the drive ring tooth 5331 is sufficient to ensure that it remains within the meshing range of the drive ring tooth 5331 during the rotation and descent of the transmission gear 5333. The length of the inner sliding groove of the limiting sliding plate 432 is also sufficient to meet the sliding requirements of the sliding seat 433. The specific dimensions are set according to the required depth of insertion of the vertical drilling rod 21 and the inclined drilling rod 31 into the ground surface.

[0092] The rotary drive assembly 5 also includes three sets of inclined connecting plates 54 arranged in a ring around the axis of the vertical fixing assembly 2. The inclination angle of the inclined connecting plates 54 is perpendicular to the inclination angle of the inclined drilling rod 31. The inclined connecting plates 54 are fixedly connected to the support sleeve 531 and the inclined connecting plates 54 are fixedly connected to the inclined guide seat 32.

[0093] The inclined connecting plate 54 enables the inclined guide seat 32 to be stably installed on the support plate 12.

[0094] The bottom of the support plate 12 is provided with anti-slip texture 13 to increase friction with the inclined ground.

[0095] The anti-slip texture 13 increases friction with the ground, thereby increasing the stability of the mining vehicle during operation.

[0096] The linear limiting rod 41 is a linear actuator.

[0097] The position of the lifting frame 42 can be better controlled by a linear actuator. The descent height and rotation speed are automatically controlled by the equipment's electrical control system, enabling the vertical drilling rod 21 and the inclined drilling rod 31 to perform downward drilling functions.

[0098] When using the aforementioned landslide-resistant mining equipment for slope mining, the following steps are included:

[0099] S1: Before mining operations, the mining vehicle is driven to the designated work area. The drive unit on the mining vehicle drives the support device to descend to the working position. The support plate 12 in the support device is in contact with the surface of the mine slope.

[0100] S2: The rotary drive assembly 5 controls the vertical drilling rod 21 in the vertical fixing assembly 2 to rotate around its own axis, so that the vertical drilling rod 21 can be smoothly inserted into the soil layer in a direction perpendicular to the slope surface; the rotary drive assembly 5 also controls the rotation of the inclined drilling rod 31 in the triangular inclined fixing assembly 3, and the inclined drilling rod 31 is gradually driven into the soil layer along its inclined direction. The three inclined drilling rods 31 expand outward at intervals of 120 degrees, firmly inserting the equipment into the soil layer;

[0101] S2: During the rotation of the rotary drive assembly 5, the lifting frame 42 inside the mounting frame 1 is raised and lowered as needed, so that the vertical drilling rod 21 and the inclined drilling rod 31 can be lowered to the predetermined position to achieve the drilling and fixing effect.
