Description

Technical Field

[0001] This application belongs to the field of mechanical equipment technology, specifically relating to a stacker-reclaimer. Background Technology

[0002] In related technologies, stacker-reclaimers are prone to collapse of their drive platform during use, posing a safety risk to personnel and equipment. Summary of the Invention

[0003] This application provides a stacker-reclaimer, which aims to at least partially solve the problem of the drive platform collapsing during the use of the stacker-reclaimer, so as to avoid the safety risks to personnel and equipment.

[0004] This application is achieved through the following technical solution:

[0005] A stacker-reclaimer includes: a rotary platform; a drive platform spaced apart above the rotary platform; a cantilever assembly mounted on the drive platform; and a roller assembly including a bracket and rollers, wherein the top of the bracket is rotatably connected to the drive platform, and the bottom of the bracket is provided with at least two rollers, which are rotatably connected to the top surface of the drive platform.

[0006] When the stacker-reclaimer provided in this application is in operation, the cantilever assembly tilts, causing the drive platform to move back and forth relative to the rotary platform. Simultaneously, the support of the towing wheel assembly rotates relative to the drive platform and rolls back and forth on the rotary platform via rollers at its bottom. That is, the support of the towing wheel assembly in this application has at least three points of contact with the drive platform and the rotary platform to distribute the forces exerted on the rotary platform by the drive platform and cantilever assembly during movement, thereby reducing the stress at the contact points and preventing the risk of the support detaching from the drive platform and / or the rotary platform. This, to a certain extent, mitigates the possibility of drive platform collapse and ensures the safety of personnel and equipment.

[0007] In some embodiments, the top of the bracket is rotatably connected to the drive platform via a first pivot, at least two rollers are spaced apart along the extension direction of the rotary platform, and each roller is rotatably connected to the bottom of the bracket via a corresponding second pivot, wherein: along the direction from the drive platform to the rotary platform, the projection of the first pivot on the rotary platform is located between the projections of the two second pivots on the rotary platform.

[0008] In some implementations, two rollers are spaced apart along the extension direction of the rotary platform, and along the direction from the drive platform to the rotary platform, the projection of the first rotating shaft on the rotary platform is located between the projections of the two second rotating shafts on the rotary platform.

[0009] In some implementations, the bottom surface of the drive platform is connected to two opposing lugs, the top of the bracket passes between the two lugs, and the two lugs are rotatably connected by a first pivot.

[0010] In some implementations, the top surface of the rotary platform is provided with a guide groove, and at least two rollers at the bottom of the support roll within the guide groove.

[0011] In some implementations, the width of the guide groove is adapted to the axial length of the roller.

[0012] In some implementations, the support is triangular.

[0013] In some implementations, there are two or more brackets.

[0014] In some implementations, three supports are provided, and the projections of the three supports on the rotary platform form an isosceles triangle.

[0015] In some embodiments, the rotary platform includes: a fixed base; a support base mounted on the fixed base, wherein at least two rollers are rotatably connected to the top surface of the support base. Attached Figure Description

[0029] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0030] Figure 1 A schematic diagram of a stacker-reclaimer in the related art is shown, combined with Figure 1In related technologies, a stacker-reclaimer includes a rotary platform 100, a drive platform 200, a support arm 300, and a cantilever assembly 400. The drive platform 200 is positioned above the rotary platform 100. The bottom of the support arm 300 is rotatably connected to the rotary platform 100, and the top of the support arm 300 is rotatably connected to the drive platform 200. The cantilever assembly 400 includes a drive motor 401, a reducer 402, a coupling 403, a support 404, a cantilever 405, and a telescopic component. The drive motor 401, coupling 403, and reducer 402 are mounted on the drive platform 200. The cantilever 405 is located outside the drive platform 200. The drive motor 401 is connected to the reducer 402 via the coupling 403. One end of the reducer 402 is connected to the drive roller 404 of the cantilever 405, driving the belt on the cantilever to transport materials. The input shaft and output shaft of the reducer 402 are perpendicular to each other. The cantilever 405 is hinged to the support 404 on the side closest to the drive roller. The fixed end of a telescopic component, such as a hydraulic cylinder, is hinged to the support or the rotary platform 100, while the telescopic end is hinged to the middle of the cantilever 405, driving the cantilever 405 to pitch around the support 404. Due to the structural position of the cantilever 405, the drive platform 200 is relatively high above the rotary platform 100. Since the cantilever 405 needs to pitch up and down, the drive motor 401, reducer 402, and coupling 403 cannot be fixedly placed. Therefore, in related technologies, the drive platform 200 is a suspended structure, with the drive platform 200, drive motor 401, reducer 402, and coupling 403 suspended relative to the rotary platform 100, and supported above the rotary platform 100 by the support arm 300. The two ends of the support arm 300 are connected to the drive platform 200 and the rotary platform 100 by joint bearings, which can realize rotation. The drive platform 200 can swing up and down and move left and right through the support arm 300.

[0031] Figure 2 as well as Figure 3 It shows Figure 1 A schematic diagram of the stacker-reclaimer's working status. For ease of description, Figure 2 as well as Figure 3 It has front-back and up-down directions, where the front-back direction is the left-right direction shown in the diagram, and the up-down direction is the height direction shown in the diagram. (Combined) Figure 2 as well as Figure 3 Due to the influence of material height, the cantilever 405 of the stacker-reclaimer needs to be raised during the stacking and reclaiming processes. Figure 3 (as shown) or lower the cantilever 405 ( Figure 2(As shown). Therefore, the tail of the cantilever 405 also needs to perform a small-angle pitching motion, which requires the drive motor 401, coupling 403, reducer 402, and drive platform 200 to move forward and backward and up and down in a small manner. During the downward pitching motion of the cantilever 405, since both ends of the drive platform 200 can rotate freely, the tail of the cantilever 405 (where the drive roller is located) is slightly raised, causing the drive platform 200, reducer 402, and coupling 403 to move forward and upward, and the drive platform 200 to move the support arm 300 forward; during the upward pitching motion of the cantilever 405, the tail of the cantilever 405 (where the drive roller is located) is slightly pressed down, causing the drive platform 200 to move backward and downward, and the drive platform 200 to move the support arm 300 backward.

[0032] In the process of implementing the above technical solution, the applicant discovered at least the following shortcomings in the relevant technology:

[0033] Since the support arm 300 is in point contact with the drive platform 200 above and the rotary platform 100 below, if the strength of the contact point is insufficient, there is a risk that the support arm 300 will detach from the drive platform 200 and / or the rotary platform 100. In addition, if the support arm 300 itself is not strong enough during long-term use, it is also easy to bend, which may cause the drive platform 200 to collapse, thereby creating safety risks to personnel and equipment.

[0034] Based on the above-mentioned technical problems, this application provides a stacker-reclaimer to solve the problem of the collapse of the drive platform 200 used by the cantilever 405 of the stacker-reclaimer due to insufficient strength of the connection position of the support arm 300 and its own strength, thereby reducing the safety risks to personnel and equipment and improving the safety of the job.

[0035] Figure 4 The diagram shows a schematic representation of a stacker-reclaimer according to one or more embodiments of this application. Figure 5 It shows Figure 4 An assembly diagram of the rotary platform 10 and the drive platform 200. (Combined with...) Figure 4 as well as Figure 5 The stacker-reclaimer provided in this application includes a rotary platform 100, a drive platform 200, a roller assembly 500, and a cantilever assembly 400. The rotary platform 100 is spaced above the drive platform 200. The cantilever assembly 400 is mounted on the drive platform 200. The roller assembly 500 includes a bracket 501 and rollers 502. The top of the bracket 501 is rotatably connected to the drive platform 200. At least two rollers 502 are provided at the bottom of the bracket 501. The at least two rollers 502 are rotatably connected to the top surface of the drive platform 200.

[0036] When the stacker-reclaimer provided in this application is in operation, the cantilever assembly 400 tilts, causing the drive platform 200 to move back and forth relative to the rotary platform 100. Simultaneously, the support 501 of the towing wheel assembly 500 rotates relative to the drive platform 200 and rolls back and forth on the rotary platform 100 via the rollers 502 at its bottom. That is, the support 501 of the towing wheel assembly 500 in this application has at least three points of contact with the drive platform 200 and the rotary platform 100 to distribute the forces exerted on the rotary platform 100 by the drive platform 200 and the cantilever assembly 400 during movement, thereby reducing the stress at the contact points and preventing the risk of the support 501 detaching from the drive platform 200 and / or the rotary platform 100. Furthermore, compared to the support arm 300 configuration in related technologies, the support 501 has better inherent strength, thus mitigating the risk of the drive platform 200 collapsing and ensuring the safety of personnel and equipment.

[0037] Combination Figure 4 In some embodiments, the rotary platform 100 includes a fixed base 101 and a support base 102. The fixed base 101 can be fixed to the construction ground by welding, screw connection, or other methods. The support base 102 is assembled onto the fixed base 101 by welding, screw connection, or other methods. At least two rollers 502 are rotatably connected to the top surface of the support base 102. This configuration, by adding the support base 102 to the fixed base 101, reduces the distance between the rotary platform 100 and the drive platform 200, thereby reducing the height of the support 501 located between the rotary platform 100 and the drive platform 200, and thus reducing the manufacturing cost of the support 501. Furthermore, if the drive platform 200 still collapses, the reduced distance between the rotary platform 100 and the drive platform 200 correspondingly reduces the impact force of the collapsed drive platform 200 on the rotary platform 100, thereby minimizing damage.

[0038] Combination Figure 5 In some embodiments, the top surface of the rotary platform 100 is provided with a guide groove 103, and at least two rollers 502 at the bottom of the support 501 roll within the guide groove 103. This arrangement can restrict the rollers 502 through the guide groove, avoiding safety hazards caused by the rollers 502 detaching from the preset position on the top surface of the rotary platform 100.

[0039] In some embodiments, the width of the guide groove 103 is adapted to the axial length of the roller 502 to limit the movement direction of the roller 502 in the guide groove 103, so that the roller 502 can only move in a set direction.

[0040] In specific implementation, the top surface of the support base 102 is flat, and a guide groove 103 is provided in the middle of the top surface of the support base 102 along the front-back direction. The depth of the guide groove 103 is less than the diameter of the roller 502, so that there is a distance between the bottom of the bracket 501 and the top surface of the support base 102, avoiding interference between the bottom of the bracket 501 and the top surface of the support base 102, and allowing the bracket 501 to roll smoothly on the top surface of the support base 102. In addition, the width of the guide groove 103 is slightly larger than the axial length of the roller 502, so that the roller 502 can be intermittently disposed in the guide groove 103, which restricts the movement direction of the roller 502 in the guide groove 103 while allowing the roller 502 to roll smoothly in the guide groove 103.

[0041] Figure 6 It shows Figure 5 A frontal view diagram. Combined with... Figure 6 In some embodiments, the top of the bracket 501 is rotatably connected to the drive platform 200 via a first rotating shaft 503. At least two rollers 502 are spaced apart along the extension direction (front-to-back direction) of the rotary platform 100. Each roller 502 is rotatably connected to the bottom of the bracket 501 via a corresponding second rotating shaft 504. The projection of the first rotating shaft 503 onto the rotary platform 100 along the direction from the drive platform 200 to the rotary platform 100 lies between the projections of the two second rotating shafts 504 onto the rotary platform 100. This arrangement allows the pressure borne by the drive platform 200 to be evenly distributed onto the rotary platform 100 through the bracket 501, thus ensuring balanced force distribution on the rotary platform 100.

[0042] In specific implementation, two rollers 502 are spaced apart along the extension direction (front-back direction) of the rotary platform 100. Along the direction from the drive platform 200 to the rotary platform 100, the projection of the first rotating shaft 503 onto the rotary platform 100 is located between the projections of the two second rotating shafts 504 onto the rotary platform 100. In other embodiments, three or more rollers 502 are spaced apart along the extension direction (front-back direction) of the rotary platform 100; this application does not impose any limitation on this.

[0043] In some embodiments, the bottom surface of the drive platform 200 is connected to two opposing lifting lugs 201. The top of the bracket 501 passes through the two lifting lugs 201 and is rotatably connected to the two lifting lugs 201 via a first rotating shaft 503, thereby achieving a rotatable connection between the bracket 501 and the drive platform 200. In specific implementations, the lifting lugs 201 can be integrally formed with the bottom surface of the drive platform 200 to ensure that the lifting lugs 201 have sufficient strength.

[0044] In another embodiment, the bottom surface of the drive platform 200 is provided with a mounting groove, and the top of the bracket 501 passes through the mounting groove and is rotatably connected to the two opposite side walls of the mounting groove via a first rotating shaft 503, so as to realize the rotatable connection between the bracket 501 and the drive platform 200. In specific implementation, the dimension of the mounting groove along the extension direction (front and back direction) of the rotary platform 100 needs to be larger than the top dimension of the bracket 501, so that when the drive platform 200 moves back and forth, the top of the bracket 501 can swing back and forth in the mounting groove.

[0045] In some embodiments, the bracket 501 is triangular, that is, the top dimension of the bracket 501 is smaller than the bottom dimension of the bracket 501, so that the top of the bracket 501 can be rotatably connected to the lug 201 on the bottom surface of the drive platform 200 while reducing the size of the bracket 501. The bottom of the bracket 501 is provided with at least two rollers 502 to reduce the manufacturing cost of the bracket 501.

[0046] Since the drive platform 200 and the cantilever assembly 400 may be quite heavy, in order to further distribute the force exerted by the drive platform 200 and the cantilever assembly 400 on the rotary platform 100, more than two supports 501 can be provided to avoid damage to the supports 501 due to excessive force and to ensure the normal operation of the machine.

[0047] In some embodiments, three supports 501 are provided, and the projections of the three supports 501 on the rotary platform 100 form an isosceles triangle, wherein the altitude of the base of the isosceles triangle is parallel to the direction of movement of the drive platform 200. The three supports 501 arranged in an isosceles triangle have stability, ensuring that the drive platform 200 runs stably and evenly on the rotary platform 100. In other embodiments, the projections of the three supports 501 on the rotary platform 100 may also be non-isosceles triangles, which can be set according to the center of gravity of the drive platform 200 and the cantilever assembly 400; or, two, four, etc., supports 501 may be provided, and this application does not impose any restrictions on this.

Figure 7 as well as Figure 8 When the stacker-reclaimer provided in this application is in operation, during the downward movement of the cantilever 405, the drive platform 200 moves forward and upward, and the drive platform 200 drives the support 501 to roll forward. Figure 7 As shown); during the upward movement of the cantilever 405, the drive platform 200 moves backward and downward, and the drive platform 200 drives the support 501 to move backward (as shown); Figure 8As shown in the figure, it is designed to accommodate stress release and small-range displacement in all directions of the drive platform 200.
