Description

Technical Field

[0001] This application relates to the field of stacker-reclaimer technology, and in particular to a rotary mechanism for a stacker-reclaimer and a stacker-reclaimer having the same. Background Technology

[0002] Stacker-reclaimers are core equipment in bulk cargo terminals, power plants, steel mills, and other fields. They mainly consist of a slewing mechanism and a cantilever assembly. The cantilever assembly is rotatably mounted on the slewing mechanism and is used for the storage and retrieval of bulk materials (such as coal, ore, and sand). The slewing mechanism is the key component that enables the horizontal rotation of the cantilever assembly. The cantilever assembly and slewing mechanism of the stacker-reclaimer are installed integrally. The rotation of the cantilever assembly driven by the slewing mechanism determines the working coverage of the cantilever assembly, directly affecting the overall working efficiency and flexibility of the machine. The core function of the slewing mechanism is to drive the cantilever assembly (including the cantilever, counterweight, pitching mechanism, belt conveyor, etc.) to rotate precisely and smoothly horizontally around its central axis.

[0003] The slewing mechanism includes a base and a slewing bearing mounted on the base. The slewing bearing is the core load-bearing and rotating connecting component of the entire mechanism. The outer ring of the slewing bearing is usually fixed to the base with high-strength bolts, while the inner ring of the slewing bearing is usually fixed to the cantilever assembly with high-strength bolts.

[0004] The load variation of the cantilever assembly caused excessive load on the front end of the cantilever, leading to damage to the slewing bearing due to off-center loading, and resulting in the failure of the stacker-reclaimer's slewing function. Therefore, the slewing bearing needs to be replaced during equipment maintenance. During replacement, the cantilever assembly needs to be lifted to separate it from the slewing mechanism. However, the cantilever assembly is heavy, making lifting it difficult and increasing the risk of tipping over during the lifting process. Summary of the Invention

[0005] This application aims to at least solve one of the technical problems existing in the prior art. To this end, this application proposes a slewing mechanism for a stacker-reclaimer, which, by arranging multiple anti-tipping devices around the slewing bearing in the circumferential direction, can support the cantilever assembly at different positions in the circumferential direction of the slewing bearing during the lifting process, thereby reducing the risk of tipping over and other safety accidents that may occur during the lifting process of the cantilever assembly.

[0007] According to the embodiments of the stacker-reclaimer, the slewing mechanism can drive the cantilever assembly to rise or fall along the axial direction of the slewing bearing through a lifting member set on the base. This makes it easier to reduce the difficulty of lifting the cantilever assembly, thereby reducing the maintenance difficulty of the slewing bearing. At the same time, multiple anti-tipping devices set around the slewing bearing in the circumferential direction can support the cantilever assembly at different positions in the circumferential direction of the slewing bearing during the lifting process, thereby reducing the risk of tipping over and other safety accidents that may occur during the lifting process.

When the support body moves to the target position, the limiting structure limits the engagement between the support body and the anti-tipping bracket.

[0009] According to some embodiments of this application, the anti-tipping bracket is sleeved on the support body in the rotary mechanism of the stacker-reclaimer.

When the first insertion hole is opposite to any of the second insertion holes, part of the insert plate is inserted into the first insertion hole and another part is inserted into the second insertion hole.

[0011] The slewing mechanism of the stacker-reclaimer according to some embodiments of this application further includes: a displacement indicating structure, the displacement indicating structure including a positioning scale and a positioning pointer, one of the positioning scale and the positioning pointer being disposed on the anti-tipping bracket and the other being disposed on the cantilever assembly, the positioning pointer being adapted to correspond to any scale on the positioning scale.

[0012] According to some embodiments of the present application, in the slewing mechanism of a stacker-reclaimer, a baffle is provided at one end of the support body away from the base along the axial direction of the slewing bearing, and the baffle is adapted to abut against the anti-tipping bracket.

[0013] According to some embodiments of the present application, the rotary mechanism of the stacker-reclaimer includes a plurality of lifting members, which are arranged around the rotary bearing in the circumferential direction.

Detailed Implementation

[0022] To better understand the technical solutions provided in the embodiments of this specification, the technical solutions of the embodiments of this specification will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

[0023] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element. The term "two or more" includes two or more cases.

[0024] The following is in conjunction with the appendix Figure 1-6 The present application describes the rotary mechanism 100 of the stacker-reclaimer and the stacker-reclaimer 1000 having therewith.

[0025] This application proposes a stacker-reclaimer 1000, such as Figure 1 As shown, the stacker-reclaimer 1000 according to an embodiment of this application includes: a cantilever assembly 200 and a slewing mechanism 100 of the stacker-reclaimer, wherein the cantilever assembly 200 is poweredly connected to the slewing bearing 20.

[0026] It is understood that the slewing bearing 20 may include an outer ring bearing 201 and an inner ring bearing. The outer ring bearing 201 is typically fixed to the base 10 of the slewing mechanism by high-strength bolts, and the inner ring bearing is typically fixed to the cantilever assembly 200 by high-strength bolts.

[0027] In this way, the relative rotation between the cantilever assembly 200 and the rotary mechanism can be achieved through the rotational engagement of the inner ring bearing sleeve and the outer ring bearing 201.

[0028] like Figure 2 As shown, the slewing mechanism 100 of the stacker-reclaimer according to an embodiment of this application includes: a base 10, a slewing bearing 20, and a lifting member 30.

[0029] The slewing bearing 20 is mounted on the base 10 and is used to mount the cantilever assembly 200. The lifting member 30 is connected to the base 10 and is used to drive the cantilever assembly 200 to rise or fall along the axial direction of the slewing bearing 20.

[0030] It is understood that the lifting component 30 can be located on the radial outer side of the slewing bearing 20, and the lifting component 30 can be a structure such as a cylinder or hydraulic cylinder that can drive the cantilever assembly 200 to move linearly relative to the slewing mechanism 100 of the stacker-reclaimer in the axial direction of the slewing bearing 20. No limitation is made here.

[0031] Therefore, the cantilever assembly 200 can be driven to rise or fall along the axial direction of the slewing bearing 20 by the lifting member 30 provided on the base 10. For example, when the slewing bearing 20 needs to be repaired, the cantilever assembly 200 can be lifted by the lifting member 30 so that the cantilever assembly 200 is separated from the slewing mechanism 100 of the stacker-reclaimer in the axial direction of the slewing bearing 20. This makes it easier to reduce the difficulty of lifting the cantilever assembly 200, thereby reducing the difficulty of repairing the slewing bearing 20.

[0032] Furthermore, such as Figure 2 As shown, the slewing mechanism 100 of the stacker-reclaimer also includes an anti-tipping device 40.

[0033] like Figure 2 As shown, the anti-tipping device 40 is installed on the base 10 and is used to support the cantilever assembly 200. Multiple anti-tipping devices 40 are provided, and multiple anti-tipping devices 40 are arranged around the slewing bearing 20 in the circumferential direction.

[0034] Therefore, the multiple anti-tipping devices 40 arranged around the slewing bearing 20 in the circumferential direction can support the cantilever assembly 200 at different positions in the circumferential direction of the slewing bearing 20 during the lifting process, thereby reducing the risk of tipping over and other safety accidents that may occur during the lifting process of the cantilever assembly 200.

[0035] The anti-tipping device 40 can be any structure, such as a pneumatic cylinder or a hydraulic cylinder, whose length is adjustable in the axial direction of the slewing bearing 20; no specific limitation is imposed here. According to the embodiment of this application, the slewing mechanism 100 of the stacker-reclaimer can drive the cantilever assembly 200 to rise or fall along the axial direction of the slewing bearing 20 via the lifting member 30 disposed on the base 10. This facilitates the reduction of the lifting difficulty of the cantilever assembly 200, thereby reducing the maintenance difficulty of the slewing bearing 20. At the same time, the multiple anti-tipping devices 40 disposed around the slewing bearing 20 in the circumferential direction can support the cantilever assembly 200 at different positions in the circumferential direction of the slewing bearing 20 during the lifting process, thereby reducing the risk of tipping over and other safety accidents that may occur during the lifting process of the cantilever assembly 200.

[0036] In some embodiments, such as Figure 3 As shown, the anti-tipping device 40 includes an anti-tipping bracket 41, a support body 42, and a limiting structure. The anti-tipping bracket 41 is installed on the base 10. The support body 42 and the anti-tipping bracket 41 are slidably engaged in the axial direction of the slewing bearing 20 and are used to abut against the cantilever assembly 200. When the support body 42 moves to the target position, the limiting structure limits the engagement between the support body 42 and the anti-tipping bracket 41.

[0037] Understandably, when the lifting component 30 lifts the cantilever assembly 200 to a target distance from the stacker-reclaimer's slewing mechanism 100, the support body 42 needs to abut against the cantilever assembly 200. Therefore, the support body 42 moves relative to the anti-tipping bracket 41 to the target position corresponding to the target distance. At this time, the support body 42 and the anti-tipping bracket 41 can be limited by the limiting structure, thereby ensuring that the support body 42 can stably support the cantilever assembly 200.

[0038] In some embodiments, such as Figure 3 As shown, the anti-tipping bracket 41 is fitted onto the support body 42.

[0039] This allows the anti-tipping device 40 to have a more compact structure, and the anti-tipping bracket 41 can serve to house the support body 42, thereby reducing the storage volume of the anti-tipping bracket 41. Furthermore, the anti-tipping bracket 41 can guide the support body 42 when it slides relative to the anti-tipping bracket 41, thereby improving the movement stability of the support body 42.

[0040] In some embodiments, the limiting structure includes a first insertion hole, a plurality of second insertion holes 43, and an insertion plate 44, wherein the first insertion hole is disposed on the support body 42, such as Figure 3 As shown, a plurality of second insertion holes 43 are provided on the anti-tipping bracket 41 and spaced apart along the axial direction of the slewing bearing 20. When the first insertion hole is opposite to any of the second insertion holes 43, part of the insertion plate 44 is inserted into the first insertion hole and the other part is inserted into the second insertion hole 43 so that the support body 42 and the anti-tipping bracket 41 are in upper axial position engagement with the slewing bearing 20.

[0041] It is understandable that one or more first insertion holes can be provided. Since the support body 42 slides axially relative to the anti-tipping bracket 41 on the slewing bearing 20, and the anti-tipping bracket 41 is sleeved on the support body 42, when the support body 42 slides relative to the anti-tipping bracket 41, at least one first insertion hole will be misaligned with multiple second insertion holes 43, or at least one first insertion hole will be opposite to one second insertion hole 43. In this case, the insertion plate 44 can be inserted from the second insertion hole 43 into the first insertion hole, so that part of the insertion plate 44 is inserted into the first insertion hole and... Another part is inserted into the second insertion hole 43. In this way, when it is necessary to keep the distance between the cantilever assembly 200 and the slewing mechanism 100 of the stacker-reclaimer unchanged, the support body 42 and the anti-tipping bracket 41 can be limited in the axial direction of the slewing bearing 20 through the insertion plate 44. At this time, the support body 42 can be stabilized in the target position, so that the support body 42 can provide stable support for the cantilever assembly 200. At the same time, the support body 42 and the insertion plate 44 can share part of the weight of the cantilever assembly 200, thereby reducing the load on the lifting member 30.

[0042] In some embodiments, the slewing mechanism 100 of the stacker-reclaimer further includes: a displacement indicating structure 50, such as... Figure 3 As shown, the displacement indicator structure 50 includes a positioning dial 51 and a positioning pointer. One of the positioning dial 51 and the positioning pointer is disposed on the anti-tipping bracket 41, and the other is disposed on the cantilever assembly 200. The positioning pointer is adapted to correspond to any scale on the positioning dial 51.

[0043] For example Figure 3 As shown, the positioning dial 51 can be set on the anti-tipping bracket 41, and the positioning pointer can be set on the cantilever assembly 200. During the process of the lifting member 30 driving the cantilever assembly 200 to rise, the positioning pointer will move along the positioning dial 51. When the cantilever assembly 200 stops, the positioning pointer will correspond to a scale on the positioning dial 51. In this way, the lifting distance of the cantilever assembly 200 can be determined by the scale on the positioning dial 51 corresponding to the positioning pointer. Then, the lifting member 30 can be further controlled to drive the cantilever assembly 200 to rise or fall according to the lifting distance.

[0044] In some embodiments, such as Figure 3 As shown, in the axial direction of the slewing bearing 20, a baffle 421 is provided at the end of the support body 42 away from the base 10, and the baffle 421 is adapted to abut against the anti-tipping bracket 41.

[0045] In this way, even if the support body 42 is not limited to the anti-tipping bracket 41 by the limiting structure, and the support body 42 is housed in the anti-tipping bracket 41, the baffle 421 abuts against the anti-tipping bracket 41 so that the baffle 421 is located on the outside of the anti-tipping bracket 41. This makes it easier to pull the support body 42 out relative to the anti-tipping bracket 41 through the baffle 421 later, thereby avoiding the problem that the support body 42 cannot extend out of the anti-tipping bracket 41.

[0046] In some embodiments, such as Figure 2 As shown, there are multiple lifting members 30, which are arranged around the slewing bearing 20 in the circumferential direction.

[0047] Therefore, the multiple lifting members 30 arranged around the slewing bearing 20 in the circumferential direction can lift the cantilever assembly 200 at different positions in the circumferential direction of the slewing bearing 20 during the lifting process, thereby reducing the risk of tipping over and other safety accidents that may occur during the lifting process of the cantilever assembly 200.

[0048] In some embodiments, such as Figure 2 As shown, the slewing mechanism 100 of the stacker-reclaimer also includes a support device 60, which is mounted on the base 10 and used to support the cantilever assembly 200. Multiple support devices 60 are provided, and multiple support devices 60 are arranged around the slewing bearing 20 in the circumferential direction.

[0049] Therefore, the multiple support devices 60 arranged around the slewing bearing 20 in the circumferential direction can support the cantilever assembly 200 at different positions in the circumferential direction of the slewing bearing 20 when the cantilever assembly 200 is raised to a certain height, thereby reducing the risk of tipping over and other safety accidents that may occur during the lifting process of the cantilever assembly 200.

[0050] In some embodiments, the lifting member 30, the anti-tipping device 40, and the support device 60 are all disposed on the radial outer side of the slewing bearing 20, and the lifting member 30, the anti-tipping device 40, and the support device 60 are spaced apart in the circumferential direction of the slewing bearing 20.

[0051] This allows the cantilever assembly 200 to be lifted and supported at different positions in the circumferential direction of the slewing bearing 20, thereby improving the force balance of the cantilever assembly 200 and reducing the risk of tipping over during the lifting process.

[0052] In some embodiments, such as Figure 4As shown, the support structure includes a support bracket 61 and a plurality of pads 62. The support bracket 61 is disposed on the base 10. In the axial direction of the slewing bearing 20, the pads 62 are adapted to be placed at the end of the support bracket 61 away from the base 10 to abut against the cantilever assembly 200.

[0053] Thus, when the cantilever assembly 200 is raised to different heights, the number of pads 62 set on the end of the support bracket 61 away from the base 10 can be increased or decreased to support the cantilever assembly 200 at different heights.

[0054] For example Figure 5 As shown, when the lifting height of the cantilever assembly 200 is small and it is necessary to fix the cantilever assembly 200 at the current height, two pads 62 can be stacked on the end of the support bracket 61 away from the base 10. At this time, the cantilever assembly 200 can be supported by the support bracket 61 and the two pads 62.

[0055] Or such as Figure 6 As shown, when the lifting height of the cantilever assembly 200 is large and it is necessary to fix the cantilever assembly 200 at the current height, at least three pads 62 can be stacked on the end of the support bracket 61 away from the base 10. At this time, the cantilever assembly 200 can be supported by the support bracket 61 and the three pads 62.

[0056] Therefore, by increasing or decreasing the number of pads 62, support for the cantilever assembly 200 at different heights can be achieved.

[0057] This application also proposes a stacker-reclaimer 1000.

[0058] The stacker-reclaimer 1000 according to an embodiment of this application includes: a cantilever assembly 200 and a slewing mechanism 100 of the stacker-reclaimer described in any of the above embodiments, wherein the cantilever assembly 200 is poweredly connected to the slewing bearing 20.

[0059] According to the stacker-reclaimer 1000 of this application embodiment, the cantilever assembly 200 can be driven to rise or fall along the axial direction of the slewing bearing 20 by the lifting member 30 provided on the base 10. This makes it easier to reduce the difficulty of lifting the cantilever assembly 200, thereby reducing the maintenance difficulty of the slewing bearing 20. At the same time, the multiple anti-tipping devices 40 provided around the slewing bearing 20 in the circumferential direction can support the cantilever assembly 200 at different positions in the circumferential direction of the slewing bearing 20 during the lifting process, thereby reducing the risk of tipping over and other safety accidents that may occur during the lifting process of the cantilever assembly 200.
