[0002] A slewing bearing, also known as a slewing ring bearing, is a large bearing that can withstand combined loads and can simultaneously withstand large axial, radial loads and overturning moments. It usually consists of an inner ring, an outer ring, rolling elements and spacer blocks, etc. It has a compact structure and flexible rotation and can work stably under various complex working conditions;

[0021] Further, a usage method of a slewing bearing fixing device includes the following steps:

[0022] S1: A handling component is provided on the surface of the right-angled plate. When the handling component is started to move downward, the handling component will move to the inner ring of the slewing bearing, and expand inside the slewing bearing to squeeze and fix its inner wall. After the handling component contacts the surface of the slewing bearing, the slewing bearing can be transported above the clamping component through the handling component;

[0023] S2: When the electric telescopic rod moves downward, it squeezes the expansion plate, and the inclined surface frame provided at the bottom of the expansion plate limits the expansion plate.

[0025] S4: When the groove extrusion rod moves towards the surface of the disc, the seesaw will push the fixed frame to move through the lifting frame. When the fixed frame moves, it will push the lifting plate to move upward through the cylindrical elastic rod and contact the bottom of the slewing bearing, and push the slewing bearing to move upward through the lifting plate.

[0026] The present invention has the following beneficial effects:

[0027] The present invention is provided with a handling component on the surface of a right-angle plate. When the handling component is started to move downward, the handling component will move to the inner ring of the slewing bearing, and expand inside the slewing bearing to squeeze and fix its inner wall. After the handling component contacts the surface of the slewing bearing, the slewing bearing can be transported above the clamping component through the handling component. After placing the slewing bearing on the top of the clamping component, the clamping component is started to squeeze and fix the slewing bearing, improving the stability of the slewing bearing during quenching treatment. A jacking component is arranged below the clamping component, and the jacking component can jack up the slewing bearing to separate it from the clamping component, so as to hoist the slewing bearing through the handling component.

[0028] The present invention starts the electric push rod to push the moving frame to move on the surface of the right-angle plate. When the moving frame moves, it pushes the sliding frame to slide on the surface of the chute plate. The slider inside the sliding frame will slide on the inner wall of the chute plate, using the slider to support the sliding frame, improving the bearing capacity and stability of the sliding frame. The hydraulic rod is started to push the electric telescopic rod to move downward. When the bottom of the inclined plane frame contacts the ground, the electric telescopic rod is started to extend downward. When the electric telescopic rod moves downward, it squeezes the expansion plate, and the inclined plane frame arranged at the bottom of the expansion plate limits the expansion plate. At this time, after the expansion plate is stressed, it will push the inclined plane frame to move away from each other. When the inclined plane frame moves, it will contact the surface of the slewing bearing and clamp it, thereby fixing the slewing bearing. An expansion rod and a sliding hole frame are arranged on the top of the inclined plane frame, using the expansion rod to squeeze the inclined plane frame to prevent the inclined plane frame from tilting upward when it moves. After the inclined plane frame fixes the slewing bearing, it is hoisted by the hydraulic rod. After the slewing bearing is hoisted, the electric push rod contracts to transport the slewing bearing to the top of the clamping component and place it on the top of the clamping component to complete the fixation, improving the convenience of the slewing bearing during handling and preventing the operator from tying the steel wire to the surface of the slewing bearing and causing burns.

[0029] After the slewing bearing is transported above the through-hole plate, the electric rod is started to push the mounting plate to move upward. When the mounting plate moves upward, it will push the rocker to move. When the I-shaped frame contacts the inner wall of the through-hole plate, it will limit the rocker. At this time, when the mounting plate moves upward, it will push the rocker to expand outward. When the rocker expands, it will push the I-shaped frame to move away from the outer end of the disc. When the extension plate moves to the bottom of the slewing bearing, after placing the slewing bearing on the top of the extension plate through the handling component, the handling component is started to separate from the surface of the slewing bearing and move upward. The groove extrusion rod continues to move and contacts the slewing bearing and squeezes it to fix it, further improving the stability of the slewing bearing during quenching treatment. The extension plate can support the slewing bearing to prevent the slewing bearing from falling off when placed on the surface of the groove extrusion rod.

[0030] When the clamping position of the slewing bearing needs to be adjusted in the present invention, the groove extrusion rod is pushed to move towards the surface of the disc. At this time, the groove extrusion rod will separate from the inner wall of the slewing bearing. After the groove extrusion rod separates from the inner wall of the slewing bearing, the extension plate will support the slewing bearing. When the groove extrusion rod moves towards the surface of the disc, the rocker will push the fixed frame to move through the lifting frame. When the fixed frame moves, it will push the lifting plate to move upward through the cylindrical elastic rod and contact the bottom of the slewing bearing. The slewing bearing is pushed upward by the lifting plate. At this time, the handling component is started to move downward, and the bottom of the inclined plane frame will contact the top of the lifting plate and slide on the top of the lifting plate, so that the inclined plane frame can hoist the slewing bearing. At this time, the groove extrusion rod is pushed to move towards the end away from the disc. When the groove extrusion rod moves to the surface of the slewing bearing, after the slewing bearing is placed on the top of the extension plate, the groove extrusion rod is pushed to move towards the surface of the disc. At this time, the groove extrusion rod can extrude and fix the surface of the slewing bearing, further improving the convenience of the slewing bearing when changing the clamping position.

[0031] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

A sliding hole frame 21 is slidably connected to the surface of the cross 12. A telescopic rod 18 is fixedly connected to the bottom of the sliding hole frame 21. In the present invention, when the electric push rod 10 is started to push the moving frame 22 to move on the surface of the right-angle plate 2, the moving frame 22 pushes the sliding frame 23 to slide on the surface of the chute plate 11 during the movement. The slider 24 inside the sliding frame 23 will slide on the inner wall of the chute plate 11, using the slider 24 to support the sliding frame 23, improving the bearing capacity and stability of the sliding frame 23. The hydraulic rod 25 is started to push the electric telescopic rod 20 to move downward. When the bottom of the inclined plane frame 16 contacts the ground, the electric telescopic rod 20 is started to extend downward. When the electric telescopic rod 20 moves downward, it squeezes the expansion plate 15, and the inclined plane frame 16 provided at the bottom of the expansion plate 15 limits the expansion plate 15. At this time, the expansion plate 15 will push the inclined plane frame 16 to move away from each other after being stressed.

An expansion plate 15 is hinged to the inner wall of the limiting frame 13;

[0050] One end of the expansion plate 15 away from the limiting frame 13 is hinged to the surface of the inclined plane frame 16. A spring piece 14 is fixedly connected to the surface of the telescopic rod 18. A telescopic round rod 19 is fixedly connected to the bottom of the limiting frame 13. A cross contact frame 17 is fixedly connected to the bottom of the telescopic round rod 19.

[0051] The end of the moving frame 22 extends to the surface of the chute plate 11. The inner wall of the sliding frame 23 contacts the surface of the chute plate 11. When the inclined plane frame 16 moves, it will contact the surface of the slewing bearing and jam it, thereby fixing the slewing bearing. An expansion rod 18 and a sliding hole frame 21 are arranged at the top of the inclined plane frame 16. The expansion rod 18 is used to extrude the inclined plane frame 16 to prevent the inclined plane frame 16 from tilting upwards when moving. After the inclined plane frame 16 finishes fixing the slewing bearing, the hydraulic rod 25 is used to lift it. After lifting the slewing bearing, the electric push rod 10 contracts to carry the slewing bearing to the top of the clamping component 4 and place it on the top of the clamping component 4 to complete the fixation, improving the convenience of handling the slewing bearing and preventing the operator from tying the steel rope to the surface of the slewing bearing and causing burns. The surface of the slider 24 is slidably connected to the inner wall of the chute plate 11.

The bottom of the electric rod 42 is fixedly connected with a mounting disc 39. A rocker 32 is hinged to the inner wall of the mounting disc 39. One end of the rocker 32 away from the mounting disc 39 is hinged to a telescopic frame 40. The top of the telescopic frame 40 is fixedly connected to an I-shaped frame 34. The top of the I-shaped frame 34 is fixedly connected to a groove extrusion rod 43. An extension plate 37 is fixedly connected to the surface of the groove extrusion rod 43;

[0054] A fixing rod 38 is fixedly connected to the surface of the support leg 30. One end of the fixing rod 38 away from the support leg 30 is fixedly connected to a rectangular frame 36. A rolling rod 35 is rotatably connected to the surface of the rectangular frame 36.

[0055] The end of the support 1 is fixedly connected to the surface of the support leg 30. After the slewing bearing of the present invention is transported above the through-hole plate 31, the electric rod 42 is activated to push the mounting plate 39 upward. When the mounting plate 39 moves upward, it will push the rocker 32 to move. When the I-shaped frame 34 contacts the inner wall of the through-hole plate 31, it will limit the rocker 32. At this time, when the mounting plate 39 moves upward, it will push the rocker 32 to expand outward. When the rocker 32 expands, it will push the I-shaped frame 34 to move towards the outer end away from the disk 41. When the extension plate 37 moves to the bottom of the slewing bearing, after the slewing bearing is placed on the top of the extension plate 37 by the handling component 3, the handling component 3 is activated to separate from the surface of the slewing bearing and move upward. The groove extrusion rod 43 continues to move and contacts the slewing bearing and squeezes and fixes it, further improving the stability of the slewing bearing during quenching treatment. The extension plate 37 can support the slewing bearing to prevent the slewing bearing from falling off when placed on the surface of the groove extrusion rod 43.

[0059] The inner wall of the lifting frame 50 is slidably connected to the surface of the electric rod 42. When the clamping position of the slewing bearing needs to be adjusted in the present invention, the pushing groove squeezes the rod 43 to move towards the surface of the disc 41. At this time, the groove squeezing rod 43 will separate from the inner wall of the slewing bearing. After the groove squeezing rod 43 separates from the inner wall of the slewing bearing, the extension plate 37 will support the slewing bearing. When the groove squeezing rod 43 moves towards the surface of the disc 41, the rocker plate 32 will push the fixed frame 51 to move through the lifting frame 50. When the fixed frame 51 moves, it will push the lifting plate 54 to move upward through the cylindrical elastic rod 53 and contact the bottom of the slewing bearing. The slewing bearing is pushed upward by the lifting plate 54. At this time, the handling component 3 is started to move downward. The bottom of the inclined surface frame 16 will contact the top of the lifting plate 54 and slide on the top of the lifting plate 54, so that the inclined surface frame 16 can lift and transport the slewing bearing. At this time, the groove squeezing rod 43 is pushed to move towards one end away from the disc 41. When the groove squeezing rod 43 moves to the surface of the slewing bearing, after placing the slewing bearing on the top of the extension plate 37, the groove squeezing rod 43 is pushed to move towards the surface of the disc 41. At this time, the groove squeezing rod 43 can squeeze and fix the surface of the slewing bearing, further improving the convenience when the clamping position of the slewing bearing is changed. One end of the elastic plate 52 away from the hinge frame 55 is arranged to incline downward, and there is a gap between the surface of the lifting plate 54 and the surface of the through hole plate 31.

[0060] A method for using a slewing bearing fixing device includes the following steps:

[0061] S1: A handling component 3 is arranged on the surface of the right-angle plate 2. When the handling component 3 is started to move downward, the handling component 3 will move to the inner ring of the slewing bearing and expand inside the slewing bearing to squeeze and fix its inner wall. When the handling component 3 contacts the surface of the slewing bearing, the slewing bearing can be transported above the clamping component 4 through the handling component 3;

[0062] S2: When the electric telescopic rod 20 moves downward, it squeezes the expansion plate 15, and the inclined surface frame 16 arranged at the bottom of the expansion plate 15 will limit the expansion plate 15. At this time, the expansion plate 15 will push the inclined surface frame 16 to move away from each other after being stressed. When the inclined surface frame 16 moves, it will contact the surface of the slewing bearing and clamp it;

[0063] S3: When the rocker plate 32 expands, it will push the I-shaped frame 34 to move towards the outer end away from the disc 41. After the extension plate 37 moves to the bottom of the slewing bearing, after placing the slewing bearing on the top of the extension plate 37 through the handling component 3, the handling component 3 is started to separate from the surface of the slewing bearing and move upward. The groove squeezing rod 43 continues to move to contact the slewing bearing and squeeze and fix it;

[0064] S4: When the groove extrusion rod 43 moves towards the surface of the disc 41, the rocker 32 will push the fixed frame 51 to move through the lifting frame 50. When the fixed frame 51 moves, it will push the lifting plate 54 to move upward through the cylindrical elastic rod 53 and contact the bottom of the slewing bearing, and push the slewing bearing to move upward through the lifting plate 54.

[0065] During use, start the electric push rod 10 to push the moving frame 22 to move on the surface of the right-angle plate 2. When the moving frame 22 moves, it pushes the sliding frame 23 to slide on the surface of the chute plate 11. The slider 24 inside the sliding frame 23 will slide on the inner wall of the chute plate 11, and the slider 24 is used to support the sliding frame 23 to improve the bearing capacity and stability of the sliding frame 23. Start the hydraulic rod 25 to push the electric telescopic rod 20 downward. When the bottom of the inclined plane frame 16 contacts the ground, start the electric telescopic rod 20 to extend downward. When the electric telescopic rod 20 moves downward, it squeezes the expansion plate 15, and the inclined plane frame 16 arranged at the bottom of the expansion plate 15 limits the expansion plate 15. At this time, after the expansion plate 15 is stressed, it will push the inclined plane frames 16 to move away from each other. When the inclined plane frames 16 move, they will contact the surface of the slewing bearing and clamp it, thereby fixing the slewing bearing. An expansion rod 18 and a sliding hole frame 21 are arranged at the top of the inclined plane frame 16, and the expansion rod 18 is used to squeeze the inclined plane frame 16 to prevent the inclined plane frame 16 from tilting upward when moving. After the inclined plane frame 16 fixes the slewing bearing, use the hydraulic rod 25 to lift it. After lifting the slewing bearing, the electric push rod 10 retracts to carry the slewing bearing to the top of the clamping component 4 and place it on the top of the clamping component 4 to complete the fixation, improving the convenience of handling the slewing bearing and preventing the operator from tying the steel wire to the surface of the slewing bearing and causing burns. After moving the slewing bearing above the through-hole plate 31, start the electric rod 42 to push the mounting plate 39 upward. When the mounting plate 39 moves upward, it will push the rocker 32 to move. The I-shaped frame 34 contacts the inner wall of the through-hole plate 31 to limit the rocker 32. At this time, when the mounting plate 39 moves upward, it will push the rocker 32 to expand outward. When the rocker 32 expands, it will push the I-shaped frame 34 to move away from the outer end of the disc 41. When the extension plate 37 moves to the bottom of the slewing bearing, after placing the slewing bearing on the top of the extension plate 37 through the handling component 3, start the handling component 3 to separate from the surface of the slewing bearing and move upward. The groove extrusion rod 43 continues to move and contacts the slewing bearing and squeezes and fixes it, further improving the stability of the slewing bearing during quenching treatment. The extension plate 37 can support the slewing bearing to prevent the slewing bearing from falling off when placed on the surface of the groove extrusion rod 43. When it is necessary to adjust the clamping position of the slewing bearing, push the groove extrusion rod 43 toward the surface of the disc 41. At this time, the groove extrusion rod 43 will separate from the inner wall of the slewing bearing. After the groove extrusion rod 43 separates from the inner wall of the slewing bearing, the extension plate 37 will support the slewing bearing. When the groove extrusion rod 43 moves toward the surface of the disc 41, the rocker 32 will push the fixed frame 51 to move through the lifting frame 50. When the fixed frame 51 moves, it will push the lifting plate 54 upward through the cylindrical spring rod 53 and contact the bottom of the slewing bearing. Push the slewing bearing upward through the lifting plate 54. At this time, start the handling component 3 to move downward.The bottom of the inclined plane frame 16 will contact the top of the lifting plate 54 and slide on the top of the lifting plate 54 so that the inclined plane frame 16 can lift and transport the slewing bearing. At this time, the pushing groove presses the rod 43 to move towards the end away from the disc 41. When the groove pressing rod 43 moves to the surface of the slewing bearing, after placing the slewing bearing on the top of the extension plate 37, the pushing groove presses the rod 43 to move towards the surface of the disc 41. At this time, the groove pressing rod 43 can press and fix the surface of the slewing bearing, further improving the convenience of the slewing bearing when changing the clamping position.
