Description

Technical Field

[0001] This invention relates to the field of gear processing technology, and in particular to a lifting and transporting tool for planetary gears of mining planetary reducers. Background Technology

[0002] Mining planetary reducers are power transmission mechanisms. The planetary gear train mainly consists of planetary gears, a central gear, and a planetary carrier. Planetary gears, as crucial components of the reducer, are characterized by high transmission power and high load-bearing capacity. In the planetary transmission assembly of the mining reducer, bearings, retaining rings, spacer rings, and planetary gear shafts are assembled inside the planetary gear holes. Currently, our company mainly uses manual slings and magnetic slings for lifting and transferring planetary gears during processing, resulting in low efficiency. Invention patents CN217102731U and CN207986514U disclose lifting devices for planetary gears; however, these devices suffer from unstable clamping, are prone to falling, and can easily cause safety accidents. Furthermore, during lifting and transfer, multiple manual interventions are required to hold the workpiece in place, making operation inconvenient, complex, and inefficient. Summary of the Invention

[0003] In order to solve the technical problems existing in the above-mentioned technologies, it is necessary to provide a lifting and transfer tool for planetary gears of mining planetary reducers.

[0004] A lifting and transfer device for planetary gears of a mining planetary reducer includes a base, a clamping assembly, a lifting assembly, a rotary drive assembly, a guide tube, and a hanging assembly;

[0005] The top of the base is recessed downward to form a circular groove. A sliding groove penetrating the base is provided at the bottom of the circular groove along the radial direction of the circular groove. A cover plate for closing the circular groove is provided at the top of the base.

[0006] The clamping components are slidably disposed in opposite directions within the sliding groove;

[0008] The rotary drive assembly is fitted outside the guide tube, and the lower part of the rotary drive assembly is located in the circular groove and is slidably connected to the clamping assembly.

[0009] The lifting assembly is slidably disposed inside the guide tube. Pulling the lifting assembly upward will cause the rotary drive assembly to rotate counterclockwise along the axis of the guide tube, thereby synchronously driving the clamping assembly to move along the sliding groove towards the guide tube and retract into the base. Releasing the lifting assembly will cause the rotary drive assembly to rotate clockwise along the axis of the guide tube under the action of its own weight and the restoring force of the lifting assembly, thereby synchronously driving the clamping assembly to move along the sliding groove away from the guide tube and extend outside the base.

[0010] The hanging assembly includes a hanging ring and a connecting rod. The connecting rods are respectively disposed on both sides of the guide tube. The lower end of the connecting rod is fixed to the base, and the upper end of the connecting rod is fixed to the hanging ring.

[0011] Preferably, the rotary drive assembly includes a rotary cylinder and a rotary disk. The rotary disk is disposed in a circular groove on the base and is slidably connected to the clamping assembly. The rotary cylinder is fitted over the guide tube, and the lower end of the rotary cylinder is fixed to the rotary disk as a whole.

[0012] Preferably, the rotating disk has two arc-shaped grooves, which are mirror images of each other with the axis of the guide tube as a reference. Each arc-shaped groove is slidably connected to each clamping component. One end of the arc-shaped groove is close to the edge of the rotating disk, and the other end of the arc-shaped groove is close to the center of the rotating disk.

[0013] Preferably, two guide grooves are provided on the side wall of the rotating cylinder. The two guide grooves are mirror images of each other with the axis of the guide tube as a reference, and the guide grooves extend spirally from bottom to top along the outer wall of the rotating cylinder.

[0014] Preferably, a limiting guide hole is provided on the outer wall of the guide tube, which is arranged along the axis of the guide tube and penetrates the guide tube.

[0015] Preferably, the lifting assembly includes a guide rod, a long pin, and a spring. The guide rod is slidably disposed inside the guide tube along the axis of the guide tube, with its upper end penetrating the top of the guide tube. The long pin is disposed at the lower end of the guide rod along the radial direction of the guide rod, with both ends of the long pin passing through the limiting guide hole on the guide tube and slidably connected to the guide groove on the rotating cylinder. The spring is fitted onto the guide rod, with its upper end contacting the top of the guide tube.

[0016] Preferably, the guide rod is provided with a handle at the top.

[0017] Preferably, the rotating cylinder is fitted with a protective sleeve, the length of which is less than the length of the guide tube, and the lower end of the protective sleeve is fixed to the cover plate as a whole.

[0018] Preferably, the clamping assembly includes a clamping key block, which is slidably disposed in a sliding groove. The upper part of the clamping key block near the guide tube is provided with a connecting pin that can be inserted into the arc-shaped sliding groove, and the connecting pin is slidably connected to the arc-shaped sliding groove.

[0019] Preferably, the end of the clamping key block away from the connecting pin is provided with a supporting boss, and the side of the supporting boss has an arc-shaped structure.

The rotary drive assembly can rotate counterclockwise along the axis of the guide tube to synchronously drive the clamping assembly to move along the sliding groove towards the guide tube and retract into the base, allowing the end of the clamping assembly to disengage from the planetary gear. When the lifting assembly is released, under the action of its own weight and the restoring force of the lifting assembly, the rotary drive assembly can rotate clockwise along the axis of the guide tube to synchronously drive the clamping assembly to move away from the guide tube along the sliding groove and extend outside the base, so that the clamping assembly is engaged in the planetary gear groove, clamping and fixing the planetary gear in its radial direction. The hanging assembly includes a lifting ring and a connecting rod. The connecting rod is respectively set on both sides of the guide tube, the lower end of the connecting rod is fixed to the base, and the upper end of the connecting rod is fixed to the lifting ring.

The lifting assembly 03 is slidably disposed inside the guide tube 05. Pulling the lifting assembly 03 upward will cause the rotary drive assembly 04 to rotate counterclockwise along the axis of the guide tube 05, which can synchronously drive the clamping assembly 02 to move along the sliding groove 12 towards the guide tube 05, so that the clamping assembly 02 retracts into the base 01, thereby disengaging the end of the clamping assembly 02 from the planetary gear. When the lifting assembly 03 is released, under the action of its own weight and the restoring force of the lifting assembly 03, the rotary drive assembly 04 can rotate clockwise along the axis of the guide tube 05, which can synchronously drive the clamping assembly 02 to move away from the guide tube 05 along the sliding groove 12, so that the clamping assembly 02 extends outside the base 01, and the end of the clamping assembly 02 is inserted into the planetary gear groove, clamping and fixing the planetary gear in its radial direction.

[0038] Specifically, two arc-shaped slides 43 are provided on the rotating disk 42. The two arc-shaped slides 43 are mirror images of each other with the axis of the guide tube 05 as a reference. Each arc-shaped slide 43 is slidably connected to each clamping component 02. One end of the arc-shaped slide 43 is close to the edge of the rotating disk 42, and the other end of the arc-shaped slide 43 is close to the center of the rotating disk 42.

[0039] Specifically, two guide grooves 44 are provided on the side wall of the rotating cylinder 41. The two guide grooves 44 are mirror images of each other with the axis of the guide tube 05 as a reference. The guide grooves 44 extend spirally from bottom to top along the outer wall of the rotating cylinder 41.

[0040] In one embodiment, the clamping assembly 02 includes a clamping key block 21, which is slidably disposed within a sliding groove 12. A connecting pin 22 is provided on the upper part of the clamping key block 21 near the guide tube 05. The connecting pin 22 can be inserted into an arc-shaped sliding groove 43 and is slidably connected to the arc-shaped sliding groove 43. When the rotating cylinder 41 and the rotating disk 42 rotate synchronously, the rotating disk 42 will drive the clamping key block 21 to slide along the sliding groove 12, thereby realizing the retraction or extension of the clamping key block 21. A supporting boss 23 is provided on the end of the clamping key block 21 away from the connecting pin 22. The supporting boss 23 can support the bottom of the planetary gear, and the side of the supporting boss 23 has an arc-shaped structure. This arc-shaped structure is adapted to the inner wall of the planetary gear, which can ensure that the side of the supporting boss 23 contacts the inner wall of the planetary gear, effectively preventing the planetary gear from loosening and ensuring reliable positioning.

[0041] In one embodiment, a limiting guide hole 51 is provided on the outer wall of the guide tube 05. The limiting guide hole 51 is arranged along the axial direction of the guide tube 05 and penetrates the side wall of the guide tube 05.

[0042] In one embodiment, the lifting assembly 03 includes a guide rod 31, a long pin 32, and a spring 33.

The spring 33 is fitted onto the guide rod 31, with its upper end contacting the top of the guide tube 05. When clamping the planetary gear, first pull the handle 34 upwards. The spring 33 will be compressed, and the long pin 32 will move upwards along the limiting guide hole 51. The two ends of the long pin 32 will slide synchronously along the guide groove 44, causing the rotating cylinder 41 to rotate counterclockwise. At this time, the rotating disk 42 will rotate synchronously with the rotating cylinder 41, and drive the clamping key block 21 to move along the sliding groove 12 towards the guide tube 05, so that the clamping key block 21 retracts into the base 01. After confirming that the support boss 23 of the clamping key block 21 is located at the bottom of the planetary gear, release the handle 34. Under the action of the overall weight of the lifting assembly 03 and the recovery of the spring 33 after compression, Under the combined force, the guide rod 31 will fall downwards, which will cause the long pin 32 to move downwards along the limiting guide hole 51. The two ends of the long pin 32 will slide synchronously along the guide groove 44, causing the rotating cylinder 41 to rotate clockwise. At this time, the rotating disk 42 will rotate synchronously with the rotating cylinder 41, and drive the clamping key block 21 to move along the sliding groove 12 away from the guide tube 05, so that the clamping key block 21 extends out of the base 01.
