Description

Technical Field

[0001] This invention relates to the field of open-pit mining technology, and in particular to a movable modular belt conveyor. Background Technology

[0002] Shifting belt conveyors are widely used in open-pit mining due to their advantages such as large conveying capacity, low energy consumption, and stable operation. Existing shifting belt conveyors mainly consist of a head station, a middle frame, and a tail station. The head station is arranged at an angle off the ground and integrates a motor, conveyor rollers, and other drive mechanisms, providing the core power for belt conveying. The tail station is equipped with driven rollers and an auxiliary motor to supplement power and ensure smooth belt operation. The middle frame, as the main structure of the equipment, extends the overall conveying length. Various auxiliary components, such as load-bearing idlers, return idlers, and pressure rollers, are installed on the upper part and inside the middle frame, providing support, guidance, and limiting functions for the conveyor belt, ensuring continuous and stable material conveying.

[0003] The existing publication number is CN201310071536.8, which discloses a movable belt conveyor, including a head station, several intermediate frames, a tail station, and a conveyor belt. Its key feature is that it further includes several intermediate frames and a discharge mechanism disposed between the head station and the tail station; tracks for the discharge mechanism are provided on both sides of each intermediate frame, and the tracks on each intermediate frame are connected in series. The discharge mechanism moves along the tracks between the head station and the tail station to discharge material; the conveyor belt wraps around the head drive roller of the head station and the redirecting roller of the tail station and passes through the discharge mechanism; a receiving device is provided at the tail station; the head drive device of the head station drives the head drive roller to rotate, and the head drive roller drives the conveyor belt to move; multiple sets of idler rollers are spaced apart along the direction of conveyor belt movement on each intermediate frame. This invention enables movable discharge, allows flexible selection of the discharge position, and is convenient to operate and highly mobile.

[0004] However, existing movable modular belt conveyors have high requirements for ground bearing capacity, requiring high-standard pre-treatment of the ground, and their slow movement speed affects the efficiency of relocation operations. When conveying different types and sizes of mineral materials, the angle of the upper idler rollers needs to be adjusted accordingly. However, due to the large span of the belt conveyor and the large number of idler rollers to be adjusted, repeated measurements are required to ensure that the adjustment angle of each idler roller is consistent in order to achieve smooth connection of the conveyor belt. This not only makes the operation process cumbersome, time-consuming and labor-intensive, but also easily leads to adjustment errors due to human operation deviations, which in turn affects the stability of belt operation. Summary of the Invention

[0016] This invention features an assembly assembly with a precise docking structure between the front and rear connecting seats, combined with a coordinated design of guide grooves and guide rods. The front end of the guide groove adopts a conical horn-shaped structure, with an internal square groove that matches the external dimensions of the guide rod. The guide rod is composed of three connecting rods hinged together, allowing for multi-directional swinging. During docking, the horn-shaped groove actively guides the swinging guide rod smoothly into the square groove. This not only efficiently solves the problem of initial alignment difficulties for heavy-duty central frames but also precisely guides the two sets of central frames to complete alignment, ensuring rapid and accurate alignment of the threaded holes of the front and rear connecting seats, significantly shortening assembly time. The threaded guide rod can be removed when not in use, preventing accidental injury to personnel. The sliding shoes at the bottom of the central frame are made of wear-resistant alloy steel in a one-piece tubular structure with both ends curving upwards. This upward curving structure allows for easy crossing of ground obstacles, reducing drag resistance. The tubular structure increases the contact area with the ground, dispersing the pressure of the equipment on the ground. It is suitable for unpaved surfaces, eliminating the need for pre-hardening treatment and reducing site preparation costs. Combined with the wear-resistant material and tubular structure, single-section frame dragging and moving can be completed manually or with small machinery, solving the problem of slow movement of traditional equipment. Furthermore, it features an adjustment component. The drive motor rotates the reversing gear, which, through precise transmission via the first and second gears and the first and second racks, drives multiple sets of drive linkages within the central frame to slide synchronously. Then, through the linkage of the driven linkage, the self-aligning frame, and the second support, all side rollers swing synchronously around the first support as a fulcrum for self-alignment. This eliminates the need for manual adjustment of each group, completely avoiding the tedious operation and angle errors of repeated measurements, ensuring consistent roller adjustment and smooth belt operation. More importantly, the adjustment component features a linkage function that unlocks upon docking and locks upon separation: When the frame docks, as the guide rod inserts into the guide groove, the compression between the second and first inclined grooves synchronously pushes the transmission block and transmission rod, causing the limit pin to disengage from the first gear and automatically release the limit, providing conditions for self-aligning transmission without additional operation; when the frame separates, the return spring automatically pushes the transmission rod back to its original position, causing the limit pin to re-insert into the first gear groove, rigidly locking the adjustment component and effectively preventing the idler roller from shifting due to external pressure, ensuring the stability of the idler roller angle. The entire adjustment and locking process requires no manual intervention, is simple and convenient to operate, and can flexibly adapt to the conveying needs of different specifications of ore, further ensuring the stability and reliability of belt operation.

[0030] Please refer to Figures 1 to 10 As shown: This invention provides a movable modular belt conveyor, comprising a head body 1, a middle frame 2, a tail body 3, an upper idler roller bracket 6, a front connecting seat 7, a rear connecting seat 8, and an assembly assembly. Multiple sets of the middle frame 2 are sequentially spliced ​​onto the rear side of the head body 1. The tail body 3 is located on the rear side of the middle frame 2. Multiple sets of the upper idler roller bracket 6 are fixedly installed on the upper part of the middle frame 2. Multiple sets of the front connecting seat 7 are fixedly installed on the front side of one set of middle frames 2. Multiple sets of the rear connecting seat 8 are fixedly installed on the rear side of one set of middle frames 2. The assembly assembly is located inside the middle frame 2.

[0031] The assembly components include: a waterproof rain cover 4 and a ski boot 5. Multiple sets of waterproof rain covers 4 are provided, and the multiple sets of waterproof rain covers 4 are respectively fixedly installed on the upper part of the middle frame 2 and the rear main body 3; multiple sets of ski boots 5 are provided, and the multiple sets of ski boots 5 are fixedly installed on the bottom of the multiple sets of middle frame 2.

[0032] The assembly components also include: guide grooves 701 and guide rods 801. Multiple sets of guide grooves 701 are provided, and the multiple sets of guide grooves 701 are respectively opened inside multiple sets of front connecting seats 7; multiple sets of guide rods 801 are provided, and the multiple sets of guide rods 801 are respectively threadedly connected to multiple sets of rear connecting seats 8.

[0033] The assembly components also include: corrugated rain cover 401, which is provided in multiple sets, with each pair of corrugated rain covers 401 fixedly installed on the front and rear sides of a waterproof rain cover 4.

[0034] The specific usage and function of this embodiment are as follows: The head body 1 and tail body 3 are integrated structures. The internal drive mechanism and various idlers are assembled before leaving the factory. The middle frame 2 is also prefabricated. The upper idler bracket 6 and matching idlers and other components are precisely installed in place at the factory. During on-site assembly, each pair of adjacent middle frames 2 is connected. The front connecting seat 7 on the front side of the first middle frame 2 is aligned with the rear connecting seat 8 at the rear of the second middle frame 2, so that the front connecting seat 7 and the rear connecting seat 8 are precisely connected. Each set of guide grooves 701 has a conical horn-shaped structure at the front end and a square groove inside, the internal dimensions of which match the external dimensions of the guide rod 801. Each set of guide rods 801 is composed of three connecting rods hinged together, allowing the guide rods 801 to swing in multiple directions. During the docking process, the horn-shaped groove, in conjunction with the swingable guide rods 801, guides the guide rods 801 until they smoothly enter the square groove. After entering the square section of the guide groove, the guide rods 801 are limited by the square groove wall to maintain a straight line, ensuring connection stability. At the same time, it guides and aligns the two sets of middle frames 2, helping the front connecting seat 7 and the rear connecting seat 8 to quickly find the docking position, avoiding the problem of the two heavy sets of middle frames 2 being difficult to align initially. After the guide rods 801 and guide grooves 701 form a precise guiding fit, it ensures that the threaded holes of the rear connecting seat 8 and the front connecting seat 7 are completely aligned after docking, facilitating the screwing in of bolts for tightening and fastening, achieving rapid assembly. At the same time, the threaded guide rods 801 can be removed when not in use to avoid accidental injury. Both the head body 1 and the tail body 3 are bolted to the front and rear ends of the middle frame 2. The extendable corrugated structure of the corrugated rain cover 401 can cover the connection position of the rear connecting seat 8 and the front connecting seat 7, improving the rain and dust protection effect. During relocation, the head body 1, tail body 3, and middle frame 2 are disassembled into multiple independent modules. The head body 1 and tail body 3 are moved mechanically. Each of the multiple middle frame 2 is fixedly installed with a sliding shoe 5 at the bottom. The sliding shoe 5 is made of wear-resistant alloy steel in one piece and is a tubular structure with upward-curving and smoothly transitioning arc structure at both ends. It can easily cross small protrusions or depressions on the ground, avoiding jamming and stagnation during relocation and reducing drag resistance. The tubular structure is the main pressure-bearing area. By increasing the contact area with the ground, the weight of the middle frame 2 is evenly distributed on the contact surface, effectively dispersing the pressure of the equipment on the ground. Even on unhardened ordinary soil or gravel ground, it can prevent the equipment from sinking into the ground, eliminating the need for pre-hardening of the site and reducing site pretreatment costs. Meanwhile, the wear-resistant alloy steel material, combined with the characteristics of the tubular structure, greatly reduces the frictional resistance during sliding. The relocation of a single section of the middle frame 2 can be completed with the help of small machinery or manual dragging, significantly improving the overall relocation efficiency. Example 2

[0035] like Figures 1 to 10 As shown: Based on Embodiment 1, an adjustment component is also included, which is disposed inside the central frame 2.

[0038] The adjustment assembly further includes: a bottom roller 601, a first bracket 6021, a side roller 602, and a second bracket 6022. Multiple sets of bottom rollers 601 are provided, each rotatably connected to the upper part of multiple sets of upper roller brackets 6. Multiple sets of first brackets 6021 are provided, with the ends of every two sets of first brackets 6021 hinged to both sides of the upper part of the upper roller bracket 6. Multiple sets of side rollers 602 are provided, with one end of each set rotatably connected to the top of multiple sets of first brackets 6021. Multiple sets of second brackets 6022 are provided, with the tops of each set rotatably connected to the ends of multiple sets of side rollers 602.

[0039] The adjustment assembly also includes: a self-aligning frame 603 and a driven link 2011. Multiple sets of self-aligning frames 603 are provided, with each pair of self-aligning frames 603 being vertically slidably connected to the left and right sides of the upper roller support 6. The tops of the multiple sets of self-aligning frames 603 are respectively hinged to the ends of multiple sets of second supports 6022. Multiple sets of driven links 2011 are provided, with the tops of the multiple sets of driven links 2011 being hinged to the ends of the multiple sets of self-aligning frames 603, and the ends of the multiple sets of driven links 2011 being hinged to the inner side of the multiple sets of drive links 201.

[0040] The adjustment assembly also includes: a transmission rod 703, a return spring 704, and a limiting pin 705. Multiple sets of transmission rods 703 are provided, each slidably connected inside multiple sets of front connecting seats 7. Multiple sets of return springs 704 are provided, with one end fixedly connected inside each set of front connecting seats 7, and the other end fixedly connected to the end of each set of transmission rods 703. Multiple sets of limiting pins 705 are provided, each fixedly connected to the end of each set of transmission rods 703.

[0041] The adjustment assembly also includes: a transmission block 706, a first inclined groove 7061, and a second inclined groove 8011. Multiple sets of transmission blocks 706 are provided, and multiple sets of transmission blocks 706 are fixedly connected to the end sides of multiple sets of transmission rods 703. Multiple sets of first inclined grooves 7061 are provided, and multiple sets of first inclined grooves 7061 are respectively opened inside multiple sets of transmission blocks 706. Multiple sets of second inclined grooves 8011 are provided, and multiple sets of second inclined grooves 8011 are respectively opened at the top of multiple sets of guide rods 801.

[0042] The specific usage and function of this embodiment are as follows: When the two sets of middle frames 2 are assembled, the front connecting seat 7 and the rear connecting seat 8 are connected. The second gear 203 on the side of the rear connecting seat 8 will naturally embed into the front connecting seat 7 and mesh with the reversing gear 702 inside the front connecting seat 7. At this time, simply driving the reversing gear 702 to rotate will synchronously drive the first gear 202 and the second gear 203 meshing on its left and right sides to rotate in the same direction. When the first gear 202 and the second gear 203 rotate, they will drive the first rack 2012 and the second rack 2013 meshing with them to move linearly, thereby driving the drive connecting rod 201 inside the two sets of middle frames 2 to slide synchronously. The movement of the drive connecting rod 201 will then drive the first gear 202 and the second gear 203 inside the next set of middle frames 2 to rotate through the first rack 2012 and the second rack 2013 at its other end, realizing the segmented transmission of power. By simply activating two sets of opposing reversing gears 702, all the drive linkages 201 inside the sequentially spliced ​​central frame 2 can be driven to move synchronously. The two drive motors 9 are coaxially assembled with the corresponding reversing gears 702, directly providing a stable driving force to the overall adjustment mechanism. During the sliding of the drive linkage 201, it drives multiple sets of hinged driven linkages 2011 to swing synchronously. The swinging of the driven linkages 2011 pulls the self-aligning frame 603 to slide vertically inside the central frame 2. The vertical displacement of the self-aligning frame 603 pushes the second bracket 6022, which is hinged at its top, to move. Since the two ends of the side roller 602 are rotatably connected to the first bracket 6021 and the second bracket 6022 respectively, and the end of the first bracket 6021 is hinged to the upper roller bracket 6, the side roller 602 will swing angularly with the first bracket 6021 as the fulcrum. By sliding multiple sets of drive linkages 201 simultaneously, the side rollers 602 on all the middle frame 2 can be synchronously aligned.

[0043] Simultaneously, when the front connecting seat 7 and the rear connecting seat 8 are connected, the rear connecting seat 8 will drive the guide rod 801 to be inserted into the guide groove 701 inside the front connecting seat 7. At the same time as the guide rod 801 is inserted, the limit release action will be triggered simultaneously: during the insertion process, the guide rod 801 contacts the transmission block 706 inside the front connecting seat 7. The second inclined groove 8011 at its end is precisely fitted with the first inclined groove 7061 on one side of the transmission block 706. Under the guidance and squeezing action of the inclined surface, the guide rod 801 will push the transmission block 706 to move vertically upward. The transmission block 706 will simultaneously drive the transmission rod 703 to move. While the transmission rod 703 is stably guiding, it will simultaneously compress the reset spring 704 and pull the limit pin 705 to disengage from the tooth groove of the first gear 202, directly releasing the limit on the first gear 202, so that the first gear 202 can rotate freely. This provides the necessary conditions for the linkage transmission of the adjustment component without additional operation. When the current connecting seat 7 separates from the rear connecting seat 8, the guide rod 801 retracts accordingly. At the same time as the guide rod 801 retracts, a locking action is automatically triggered: the elastic reset action of the reset spring 704 will push the transmission rod 703 to move in the opposite direction. The transmission rod 703 will simultaneously drive the limit pin 705 to re-insert into the tooth groove of the first gear 202, forming a rigid limit lock on the first gear 202. This will fix the position of the entire adjustment assembly, effectively preventing the side rollers 602 from shifting due to external pressure during the separation of the middle frame 2, and ensuring the overall consistency of the angle of all rollers.
