Description

Technical Field

[0001] This invention relates to the field of mining equipment, and in particular to a chassis structure for an omnidirectional intelligent mining vehicle. Background Technology

[0002] Mining cars are narrow-gauge railway transport vehicles used in mines to transport bulk materials such as coal, ore, and waste rock. They are generally pulled by locomotives or winches. Mining cars are classified into five main categories according to their structure and unloading method: fixed mining cars (material cars, flatbed cars), tipper mining cars, single-sided curved rail side-discharge mining cars, bottom (side) discharge mining cars, and shuttle mining cars.

[0003] Most current mining truck chassis are low and integrally formed. However, mine surfaces are often uneven. When the mining truck moves, the chassis is often rubbed by protrusions, gravel, and other objects, which can cause damage to the chassis. Over time, this will reduce the service life of the mining truck. In addition, most existing mining trucks can only move back and forth in one direction and cannot turn around when moving in the narrow mine, making them inconvenient to use.

[0004] In view of this, it is necessary to design a chassis structure for an omnidirectional intelligent mining vehicle to overcome the above-mentioned defects. Summary of the Invention

[0005] The technical problem to be solved by the first aspect of the present invention is to provide a chassis structure for an omnidirectional intelligent mining vehicle, which can prevent the chassis from rubbing against protrusions, gravel and other objects when the mining vehicle is moving, thereby preventing damage to the chassis.

A telescopic rod is fixedly connected to the inner side of the first U-shaped rotating frame, and a connecting rod is fixedly connected to the output end of the telescopic rod. The end of the connecting rod is fixedly connected to the opposite second U-shaped rotating frame, allowing the telescopic rod to extend and retract to rotate the first and second U-shaped rotating frames, thereby causing the first base to lift relative to the second base.

The output end of the servo motor is fixedly connected to a threaded rod, and a rack is movably connected to the threaded rod. The mounting rod is connected to a gear, which is adapted to mesh with the rack to drive the mounting rod to rotate. The bottom of the mounting rod is also connected to a dual-head motor, the output end of which is connected to a rotating rod.

[0015] More preferably, the second base is further provided with a tensioning mechanism, the tensioning mechanism including multiple grooves and a mounting bracket, a rotating column one is rotatably connected to the inner side of each groove, a winding wheel one is connected to the rotating column one, and a torsion spring is provided at both ends of the outer wall of the rotating column one. A rotating column two is rotatably connected to the inner side of the mounting bracket, a winding wheel two is connected to the rotating column two, and the winding wheel two is connected to the corresponding winding wheel one via an elastic rope.

[0016] Preferably, the first base is provided with a support mechanism, which includes multiple support plates, a top plate on the top of the multiple support plates, and a baffle on the side of the top plate.

[0038] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0039] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly. For example, the term "connection" can refer to a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0040] See Figure 1 This invention discloses a chassis structure for an omnidirectional intelligent mining vehicle, comprising a first base 1, a lifting mechanism 2, and a cleaning mechanism 4. The lifting mechanism 2 is connected to the first base 1 via a transmission connection, enabling the first base 1 to be raised and lowered. This prevents the base from colliding with protrusions and causing friction during the movement of the mining vehicle, thereby reducing chassis wear and extending the service life of the mining vehicle. The cleaning mechanism 4 is located at the bottom of the first base 1 and can clean some debris located at the bottom. Therefore, during the movement of the mining vehicle, the cleaning mechanism 4 can simultaneously clean the path traversed by the mining vehicle, ensuring smooth back-and-forth movement of the mining vehicle.

[0041] Specifically, the lifting mechanism 2 includes a second base 201, which is located at both ends of the first base 1. The second base 201 has multiple inner grooves 202, and the first base 1 has a through opening 204. The through opening 204 is suitable for connecting the multiple inner grooves 202 located at the same end. A U-shaped rotating frame 1 203 is provided at one end of each inner groove 202. A U-shaped rotating frame 205 is rotatably connected to the inner end of each through opening 204. A telescopic rod 206 is fixedly connected to the inner side of the U-shaped rotating frame 1 203. A connecting rod 207 is fixedly connected to the output end of the telescopic rod 206. The end of the connecting rod 207 is fixedly connected to the U-shaped rotating frame 205, which is arranged opposite to it. Thus, the telescopic rod 206 can move through the telescopic rod 206, thereby driving the U-shaped rotating frame 1 203 and the U-shaped rotating frame 205 to rotate, thereby driving the first base 1 to lift relative to the second base 201.

[0042] See Figures 5 to 7The cleaning mechanism 4 includes a stepper motor 401, which is located at the top of the first base 1. The output end of the stepper motor 401 passes through the first base 1 and is connected to a central shaft 402. A column 403 is connected to the bottom of the central shaft 402. Multiple cleaning components, which can be cross-shaped steel blades 404, are provided on the outer periphery of the column 403 to clean debris around the periphery. In addition, an annular groove 405 is provided at the top of the column 403. A hollow column 406 is connected to the inner side of the annular groove 405. An annular groove 407 is provided at the bottom of the first base 1. The top of the hollow column 406 is rotatably connected to the inner side of the annular groove 407, so that the stepper motor 401 can drive the hollow column 406 to rotate, and at the same time drive the column 403 connected to it and the multiple cleaning components provided on the column 403 to rotate to clean smaller debris around the periphery.

[0043] In addition, since the cleaning mechanism 4 is located at the bottom of the first base 1, in order to prevent debris from damaging the stepper motor 401 used to drive the cleaning mechanism during cleaning and the movement of the mine car, a protective shell 408 is provided on the outside of the stepper motor 401 to protect it. At the same time, multiple dustproof ports 409 are provided around the protective shell 408. Dustproof ports 409 can be used to protect against dust and prevent dust from entering the stepper motor 401 and damaging it during the cleaning and movement process.

[0044] See Figures 2 to 4 The drive mechanism 3 includes a servo motor 301 and a mounting rod 305. The output end of the servo motor 301 is fixedly connected to a threaded rod 302, and a rack 303 is movably connected to the threaded rod 302. A gear 304 is connected to the top of the mounting rod 305, and the gear 304 can mesh with the rack 303 to drive the mounting rod 305 to rotate. A dual-head motor 306 is also connected to the bottom of the mounting rod 305. A rotating rod 307 is connected to the output end of the dual-head motor 306, and a hub 308 is connected to the end of the rotating rod 307, so that the hub 308 can be driven to rotate at multiple angles by the dual-head motor 306.

[0045] Specifically, the drive mechanism 3 also includes a fixed plate 309, one end of the threaded rod 302 is rotatably connected to the fixed plate 309, and the bottom of the fixed plate 309 is connected to the top of the second base 201. The rack 303 is connected to a slider 311, and the top of the second base 201 is also provided with a groove 310. The slider 311 is slidably connected in the groove 310. The sliding connection and limit are achieved by the cooperation of the slider 311 and the groove 310, so that the movement of the rack 303 is smoother.

[0046] More specifically, the servo motor 301 drives the threaded rod 302 to rotate, which in turn works with the slide groove 310 to allow the slider 311 to slide and be limited within the slide groove 310, and to allow the rack 303 to move on the threaded rod 302. At the same time, the mounting rod 305 is rotatably connected to the middle of the second base 201, and works with the rack 303 to drive the gear 304 to rotate. The gear 304 also drives the mounting rod 305 to rotate. The bottom of the mounting rod 305 is driven by a dual-head motor 306, which allows the hub 308 to rotate at multiple angles, enabling the mine car to turn around when moving in narrow spaces, thereby improving the ease of use.

[0047] See Figures 8 to 9 The second base 201 is also provided with a tensioning mechanism 5, which includes multiple grooves 501 and multiple mounting brackets 505. The multiple grooves 501 are formed on the top of the second base 201, and the multiple mounting brackets 505 are embedded in the grooves 501. Optionally, at least two grooves 501 and corresponding two mounting brackets 505 are provided, and a top plate 604 is provided on the top of the mounting brackets 505. The top plate 604 can be fixed by the mounting brackets 505, and each groove 501... A rotating column 502 is rotatably connected to the inner side of the mounting bracket 505. A winding wheel 503 is connected to the rotating column 502. Torsion springs 504 are provided at both ends of the outer wall of the rotating column 502. A rotating column 506 is rotatably connected to the inner side of the mounting bracket 505. A winding wheel 507 is connected to the winding wheel 507 via an elastic rope. The winding wheel 507 is connected to the corresponding winding wheel 503 to generate tension, thereby improving the stability of the lifting mechanism 2 in driving the first base 1 during the lifting process.

[0048] To further improve the stability of the overall structure, a support mechanism 6 is also provided on the first base 1. The support mechanism 6 includes multiple support plates 601, and a top plate 604 is provided on the top of the multiple support plates 601. The arrangement of the multiple support plates 601 can stabilize the overall structure of the vehicle body. In addition, a baffle 605 is provided on the side plate of the top plate 604. In order to enhance the stability of the support plates 601, multiple diagonal braces 602 are provided on opposite sides of the multiple support plates 601, and multiple diagonal braces 603 are provided on opposite sides of the multiple support plates 601. The diagonal braces 602 and diagonal braces 603 can further fix the support plates 601 to the first base 1, thereby improving the stability of the overall structure.
