Description

Technical Field

[0001] This utility model relates to the technical field of slewing bearing transportation, and in particular to a slewing bearing transfer device. Background Technology

[0002] Slewing bearings are a new type of mechanical component. They consist of inner and outer rings, rolling elements, etc. Slewing bearings are large bearings that can withstand comprehensive loads, including large axial and radial loads and overturning moments.

[0003] In the transportation and transfer of slewing bearings, the current common practice is to stack multiple slewing bearings sequentially on a support plate, with the holes on the slewing bearings fitting into the pre-set positioning rods on the support plate. However, this stacking method means that the loading and unloading of slewing bearings can only be accomplished through vertical movement. Especially when it is necessary to load or unload the slewing bearing at the bottom, the excessively long vertical movement significantly reduces the overall efficiency of loading, unloading, and transportation. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a slewing bearing transfer device, which employs multiple detachable and removable bearing pads for stable support and precise positioning of the slewing bearing. Each bearing pad is equipped with a through rod, which can be used to fix the slewing bearing through and thus achieve independent assembly and disassembly of a single slewing bearing. Furthermore, due to the ingenious design of the through rod, there is no concern that it will obstruct or affect the loading and unloading process of the slewing bearing, thereby improving the efficiency of loading and unloading operations and effectively ensuring the smoothness and efficiency of the loading, unloading, and transportation process.

[0006] To achieve the above objectives, this utility model proposes a slewing bearing transfer device, including a transport seat and a receiving unit disposed on the transport seat. The transport seat has casters at its bottom. The receiving unit includes multiple receiving pads arranged sequentially from top to bottom. Each receiving pad is detachable, and each receiving pad has multiple slots on its upper and lower sides for accommodating the slewing bearing. Multiple through rods are movably disposed on each receiving pad, with both ends of each through rod entering corresponding slots. Two corresponding through rods are detachably connected.

[0007] In addition, the slewing bearing transfer device proposed in the application may also have the following additional technical features:

[0008] Specifically, the transport seat has a first reserved hole, and the receiving pad has a limiting hole on one side. A limiting rod is movably arranged in a plurality of the limiting holes, and one end of the limiting rod is inserted into the first reserved hole.

[0009] Specifically, the plurality of the through rods are arranged circumferentially.

[0010] Specifically, a support platform is provided in the center of the top surface of the transport seat. The support platform is located inside the corresponding slot, and a second reserved hole for accommodating the through rod is provided on the support platform.

[0011] Specifically, the through rod is movably connected to the receiving pad, and the upper and lower ends of the through rod are respectively provided with a screw and a screw sleeve, wherein the screw and the screw sleeve are configured to cooperate, and a screw that cooperates with the screw sleeve is provided in the second reserved hole.

[0012] Specifically, the screw extends from the slot, and the sleeve is located within the slot.

[0013] Compared with the prior art, the beneficial effects of this application are:

[0014] 1. This application employs multiple detachable and removable bearing pads to provide stable support and precise positioning for the slewing bearing. Each bearing pad is equipped with a through rod, which allows for through-type positioning and fixing of the slewing bearing, thereby enabling independent assembly and disassembly of a single slewing bearing. Furthermore, due to the ingenious design of the through rod, there is no concern that it will obstruct or affect the loading and unloading process of the slewing bearing, thus improving the efficiency of loading and unloading operations and effectively ensuring the smooth and efficient loading, unloading, and transportation processes.

[0015] 2. This application employs a method of assembling the slewing bearing with multiple bearing pads, allowing the bearing pads to naturally embed between adjacent slewing bearings, forming an effective barrier. This arrangement not only enhances the stability of the slewing bearing during transportation but also provides it with additional protection, effectively reducing the risk of damage during transport.

[0016] 3. This application achieves simultaneous limiting and fixing of multiple support pads by precisely passing the limiting rod through the limiting holes on multiple support pads and firmly inserting it into the first reserved hole of the transport seat. This design significantly improves the overall stability of the slewing bearing during transportation, ensuring the safety and reliability of the transportation process.

Detailed Implementation

[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0024] The slewing bearing transfer device of this utility model embodiment will be described below with reference to the accompanying drawings.

[0025] like Figures 1-3 As shown, the slewing bearing transfer device of this utility model embodiment may include a transport seat 10 and a receiving unit 20 disposed on the transport seat 10.

[0026] The bottom of the transport seat 10 is provided with casters 103. The transport seat 10 has a first reserved hole 101, and a support platform 102 is provided in the middle of the top surface of the transport seat 10. The support platform 102 is located inside the corresponding slot 2011, and a second reserved hole 1021 is provided on the support platform 102 to accommodate the through rod 30. A screw 301 that cooperates with the screw sleeve 302 is provided in the second reserved hole 1021.

[0027] The receiving unit 20 may include a plurality of receiving pads 201 arranged sequentially from top to bottom. The receiving pads 201 are detachable, and each receiving pad 201 has a plurality of slots 2011 on its upper and lower sides for accommodating the slewing bearing 50.

[0028] It should be noted that in this embodiment, the height of the designed slot 2011 is less than half the height of the slewing bearing 50. This ingenious design allows a slewing bearing 50 to be stably limited by both upper and lower slots 2011 simultaneously, and ensures that two adjacent slewing bearings 50 remain in a non-contact state, thereby significantly improving stability during transportation and providing comprehensive protection for the slewing bearing 50.

[0029] Furthermore, when the slewing bearing 50 is mounted on the support pad 201 below, its upper side will naturally protrude from the surface of the support pad 201. This design allows operators to easily use an external crane to clamp the upper side of the slewing bearing 50, thereby easily realizing hoisting, moving and other operations, greatly improving operational efficiency.

[0030] Each receiving pad 201 is movably provided with multiple through rods 30, with both ends of each through rod 30 entering a corresponding slot 2011. Two corresponding through rods 30 are detachably connected. The multiple through rods 30 are circumferentially distributed. The through rods 30 are movably connected to the receiving pad 201, and each of the through rods 30 has a screw 301 and a screw sleeve 302 at its upper and lower ends, respectively. The screw 301 and the screw sleeve 302 are fitted together, with the screw 301 extending from its corresponding slot 2011 and the screw sleeve 302 located within its corresponding slot 2011.

[0031] It should be noted that after the slewing bearing 50 is securely mounted on the lower support pad 201, personnel can use bolts, nuts, and other fasteners to precisely fit it onto the outside of the uppermost protruding screw 301. This method of operation further limits the movement of the slewing bearing 50, effectively preventing displacement during transportation or subsequent operations, and ensuring the stability and safety of the entire device.

[0032] A limiting hole 2012 is provided on one side of the receiving pad 201. A limiting rod 40 is movably installed in a plurality of limiting holes 2012, and one end of the limiting rod 40 is inserted into the first reserved hole 101.

[0033] In this embodiment of the invention, by precisely passing the limiting rod 40 through the limiting holes 2012 on multiple receiving pads 201 and firmly inserting it into the first reserved hole 101 of the transport seat 10, the simultaneous limiting and fixing of multiple receiving pads 201 is achieved. This design significantly improves the overall stability of the slewing bearing 50 during transportation, ensuring the safety and reliability of the transportation process.

[0034] Furthermore, the receiving pad 201 described in this embodiment can rotate flexibly relative to the limiting rod 40. This feature not only facilitates the storage and organization of multiple receiving pads 201 on the transport seat 10, but also allows operators to easily control the corresponding receiving pad 201 to rotate during loading and unloading to adapt to different needs, greatly improving the ease of use.

[0035] It should be noted that the outer layer of the bearing pad 201 described in this embodiment can be made of materials with certain elasticity and shock absorption, such as rubber, silicone, polyurethane (PU), thermoplastic elastomer (TPE), which can provide all-round protection for the slewing bearing 50.

[0036] Specifically, during the actual transport of multiple slewing bearings 50, the operator first moves the transport seat 10 to the designated position. Then, the first receiving pad 201 is placed on the transport seat 10, ensuring its lower slot 2011 is accurately fitted onto the outside of the support platform 102. During this process, the through rod 30 on the first receiving pad 201 automatically rotates under the action of the screw 301 inside the second pre-drilled hole 1021, achieving a stable fixation.

[0037] Next, using an external crane or similar tool, the first slewing bearing 50 is vertically lowered so that its lower side is inserted into the groove 2011 above the first support pad 201, ensuring that the hole on the slewing bearing 50 fits onto the outside of the corresponding through rod 30. Then, the second support pad 201 is placed above the first slewing bearing 50, with its lower groove 2011 fitting onto the outside of the first slewing bearing 50, and the upper through rod 30 threaded sleeve 302 is fitted onto the lower corresponding through rod 30 thread 301. During the downward movement of the second support pad 201, the through rod 30 on it automatically rotates accordingly, achieving a threaded connection between the upper and lower through rods 30, thus completing the fixation.

[0038] Following the steps described above, the operator can sequentially stack multiple slewing bearings 50 and multiple bearing pads 201 on top of the second bearing pad 201 in an alternating manner. After the last slewing bearing 50 is placed, the operator can further limit and fix the slewing bearing 50 by fitting bolts, nuts, and other fasteners onto the outside of the uppermost protruding screw 301.

[0039] In summary, the slewing bearing transfer device of this utility model employs multiple detachable and removable bearing pads for stable support and precise positioning of the slewing bearing. Each bearing pad is equipped with a through rod, which allows for through-type positioning and fixing of the slewing bearing, thereby enabling independent assembly and disassembly of a single slewing bearing. Furthermore, due to the ingenious design of the through rod, there is no concern that it will obstruct or affect the loading and unloading process of the slewing bearing, thus improving the efficiency of loading and unloading operations and effectively ensuring the smoothness and efficiency of the loading, unloading, and transportation processes.
