Description

Technical Field

[0001] This invention relates to the field of slewing bearing fixing technology, specifically to a slewing bearing fixing device and its usage method. Background Technology

[0002] Slewing bearings, also known as turntable bearings, are large bearings capable of withstanding comprehensive loads. They can simultaneously withstand large axial and radial loads and overturning moments. They are typically composed of an inner ring, an outer ring, rolling elements, and spacers. They have a compact structure and rotate flexibly, enabling them to work stably under various complex working conditions.

[0003] Slewing bearings require surface hardening during machining. This hardening process necessitates clamping and securing the bearing. The hardening device must harden both the inner and outer rings of the slewing bearing. Switching the hardening surface of the slewing bearing requires adjusting the contact position between the clamping device and the bearing. Adjusting the bearing's position requires the operator to tie a steel cable from the crane to the surface of the bearing for fixation. However, the hardened slewing bearing has a high temperature, and the operator is easily burned when tying the steel cable to its surface. Summary of the Invention

[0004] The purpose of this invention is to provide a slewing bearing fixing device and its usage method to solve the problems mentioned in the background art.

[0011] The end of the expansion plate away from the limiting frame is hinged to the surface of the inclined frame. A spring is fixedly connected to the surface of the telescopic rod. A telescopic round rod is fixedly connected to the bottom of the limiting frame. A cross contact frame is fixedly connected to the bottom of the telescopic round rod.

[0012] Furthermore, the end of the movable frame extends to the surface of the slide plate, the inner wall of the sliding frame contacts the surface of the slide plate, the surface of the slider is slidably connected to the inner wall of the slide plate, and four sliding hole frames are provided, which are arranged circumferentially around the cross as the center.

[0013] Furthermore, the end of the cross contact frame contacts the surface of the expansion plate, and four expansion plates are provided. The four expansion plates are arranged in a circle around the limiting frame, and the ends of the four expansion plates away from the limiting frame are arranged to be far apart from each other.

[0014] Furthermore, the clamping component includes an electric rod, the top of which is fixedly connected to the bottom of the disc, a mounting plate is fixedly connected to the bottom of the electric rod, a rocker arm is hinged to the inner wall of the mounting plate, a telescopic frame is hinged to the end of the rocker arm away from the mounting plate, an I-beam is fixedly connected to the top of the telescopic frame, a grooved pressing rod is fixedly connected to the top of the I-beam, and an extension plate is fixedly connected to the surface of the grooved pressing rod.

[0015] A fixing rod is fixedly connected to the surface of the support leg, and a rectangular frame is fixedly connected to the end of the fixing rod away from the support leg. A roller is rotatably connected to the surface of the rectangular frame.

[0016] Furthermore, the end of the bracket is fixedly connected to the surface of the support leg, and four arc plates are provided, which are arranged circumferentially around the disk. The end of the I-beam extends to the outer end of the through-hole plate.

[0017] Furthermore, the inner wall of the I-beam frame contacts the inner wall of the through-hole plate, and the surface of the grooved extrusion rod is provided with two extension plates, which are symmetrically arranged with the grooved extrusion rod as the center. The rectangular frame is located below the rocker, and the surface of the roller contacts the surface of the rocker.

[0018] Furthermore, the lifting component includes an elastic plate, the surface of which is rotatably connected to the inner wall of the hinge frame, and the end of the elastic plate away from the hinge frame is hinged to the surface of the rocker. A fixing frame is fixedly connected to the surface of the hinge frame.

[0019] A cylindrical spring rod is fixedly connected to the top of the fixed frame, and a lifting plate is fixedly connected to the top of the cylindrical spring rod.

[0020] Furthermore, the inner wall of the lifting frame is slidably connected to the surface of the electric rod, the end of the elastic plate away from the hinge frame is inclined downward, and a gap is provided between the surface of the lifting plate and the surface of the through-hole plate.

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

[0022] S1: A conveying component is provided on the surface of the right-angle plate. When the conveying component is activated to move downward, it 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 conveying component contacts the surface of the slewing bearing, the slewing bearing can be moved above the clamping component through the conveying component.

[0023] S2: When the electric telescopic rod moves downward, it squeezes the expansion plate, and the inclined frame at the bottom of the expansion plate limits the expansion plate. At this time, the expansion plate will push the inclined frame to move away from each other after being subjected to force. When the inclined frame moves, it will contact the surface of the slewing bearing and lock it.

[0024] S3: When the rocker expands, it will push the I-beam to move away from the outer end of the disc. When the extension plate moves to the bottom of the slewing bearing, the slewing bearing is placed on the top of the extension plate by the transport component. Then, the transport component is activated to separate from the surface of the slewing bearing and move upward. The grooved extrusion rod continues to move and contact the slewing bearing and extrudes and fixes it.

[0025] S4: When the grooved extrusion rod moves toward 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 spring rod and contact the bottom of the slewing bearing. The lifting plate will then push the slewing bearing to move upward.

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

[0027] This invention features a conveying component on the surface of a right-angle plate. When the conveying component is activated and moves downward, it moves to the inner ring of the slewing bearing and expands inside the bearing to press and fix its inner wall. Once the conveying component contacts the surface of the slewing bearing, it can transport the slewing bearing above the clamping component. After the slewing bearing is placed on top of the clamping component, the clamping component is activated to press and fix the slewing bearing, improving its stability during quenching. A lifting component is provided below the clamping component, which can lift the slewing bearing and separate it from the clamping component, allowing the conveying component to lift the slewing bearing.

[0028] This invention activates an electric actuator to move a movable frame across the surface of a right-angle plate. As the movable frame moves, it pushes a sliding frame across the surface of a sliding groove plate. A slider inside the sliding frame slides along the inner wall of the sliding groove plate, providing support and improving the frame's load-bearing capacity and stability. A hydraulic actuator then moves an electric telescopic rod downwards. Once the bottom of the inclined frame contacts the ground, the electric telescopic rod extends downwards, compressing the expansion plate. The inclined frame at the bottom of the expansion plate then limits its movement. Under this pressure, the expansion plate pushes the inclined frames away from each other. The inclined frame moves and contacts the surface of the slewing bearing, locking it in place and thus securing the bearing. A telescopic rod and sliding hole frame are installed at the top of the inclined frame. The telescopic rod compresses the inclined frame, preventing it from tilting upwards during movement. After the inclined frame secures the slewing bearing, a hydraulic rod lifts it up. Once lifted, the electric actuator retracts, moving the slewing bearing to the top of the clamping component and securing it there. This improves the ease of handling the slewing bearing and prevents operators from getting burned by tying steel cables to the surface of the bearing.

[0029] After the slewing bearing is moved above the through-hole plate, the electric lever is activated to push the mounting plate upward. As the mounting plate moves upward, it pushes the rocker to move. The contact between the I-beam and the inner wall of the through-hole plate limits the rocker. At this time, as the mounting plate moves upward, it pushes the rocker to expand outward. As the rocker expands, it pushes the I-beam to move away from the outer end of the disc. When the extension plate moves to the bottom of the slewing bearing, the slewing bearing is placed on top of the extension plate by the transport component. The transport component is then activated to separate from the surface of the slewing bearing and move upward. The grooved extrusion rod continues to move and contact the slewing bearing, extruding and fixing it, further improving the stability of the slewing bearing during quenching. The extension plate can support the slewing bearing, preventing it from falling off when placed on the surface of the grooved extrusion rod.

[0030] When the clamping position of the slewing bearing needs to be adjusted, the grooved pressing rod is pushed towards the surface of the disc. At this time, the grooved pressing rod will separate from the inner wall of the slewing bearing. After the grooved pressing rod separates from the inner wall of the slewing bearing, the extension plate will support the slewing bearing. When the grooved pressing 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 upward through the cylindrical spring rod and contact the bottom of the slewing bearing. The lifting plate will push the slewing bearing upward. At this time, the transport component will be activated to move downward. The bottom of the inclined frame will contact the top of the lifting plate and slide on the top of the lifting plate so that the inclined frame can lift the slewing bearing. At this time, the grooved pressing rod is pushed towards the end away from the disc. After the grooved pressing rod moves to the surface of the slewing bearing, the slewing bearing is placed on the top of the extension plate. The grooved pressing rod is then pushed towards the surface of the disc. At this time, the grooved pressing rod can press and fix the surface of the slewing bearing, further improving the convenience of changing the clamping position of the slewing bearing.

[0031] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Please see Figures 1-9 As shown, the present invention is a slewing bearing fixing device and its usage method, including a bracket 1, a right-angle plate 2 fixedly connected to the top of the bracket 1, and further including:

[0046] The transport component 3 includes an electric push rod 10, the end of which is fixedly connected to the top of the right-angle plate 2, a sliding groove plate 11 is fixedly connected to the top of the inner wall of the right-angle plate 2, and a movable frame 22 is fixedly connected to the telescopic end of the electric push rod 10.

[0047] The clamping component 4 includes a disc 41, a through-hole plate 31 fixedly connected to the surface of the disc 41, an arc plate 33 fixedly connected to the surface of the through-hole plate 31, and a support leg 30 fixedly connected to the bottom of the arc plate 33.

[0048] The lifting component 5 includes a lifting frame 50. A transport component 3 is provided on the surface of the right-angle plate 2. When the transport component 3 is activated to move downwards, it moves to the inner ring of the slewing bearing and expands inside the slewing bearing to press and fix its inner wall. After the transport component 3 contacts the surface of the slewing bearing, it can transport the slewing bearing to the top of the clamping component 4. After placing the slewing bearing on top of the clamping component 4, the clamping component 4 is activated to press and fix the slewing bearing, improving the stability of the slewing bearing during quenching. A lifting component 5 is provided below the clamping component 4. The lifting component 5 can lift the slewing bearing and separate it from the clamping component 4 so that the slewing bearing can be hoisted by the transport component 3. A hinge frame 55 is fixedly connected to the surface of the lifting frame 50.

[0049] The transport component 3 includes a sliding frame 23, the surface of which is fixedly connected to the end of the movable frame 22. A slider 24 is fixedly connected to the inner wall of the sliding frame 23. A hydraulic rod 25 is fixedly connected to the bottom of the sliding frame 23. An electric telescopic rod 20 is fixedly connected to the bottom of the hydraulic rod 25. A cross 12 is fixedly connected to the upper surface of the electric telescopic rod 20. 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. When the present invention is activated, the electric push rod 10 pushes the movable frame 22 to move on the surface of the right-angle plate 2. When the movable frame 22 moves, it pushes the sliding frame 23 to slide on the surface of the slide plate 11. The slider 24 inside the sliding frame 23 will slide on the slide plate 11. The sliding mechanism slides along the inner wall, using the slider 24 to support the sliding frame 23, thereby improving the load-bearing capacity and stability of the sliding frame 23. The hydraulic rod 25 is activated to push the electric telescopic rod 20 downward. When the bottom of the inclined frame 16 contacts the ground, the electric telescopic rod 20 is activated to extend downward. When the electric telescopic rod 20 moves downward, it squeezes the expansion plate 15. The inclined frame 16 at the bottom of the expansion plate 15 will limit the expansion plate 15. At this time, the expansion plate 15 will be pushed by the force to move the inclined frame 16 away from each other. The bottom of the telescopic rod 18 is fixedly connected to the inclined frame 16, and the bottom of the electric telescopic rod 20 is fixedly connected to the limit frame 13. The inner wall of the limit frame 13 is hinged to the expansion plate 15.

[0050] The end of the expansion plate 15 away from the limit frame 13 is hinged to the surface of the inclined 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 limit frame 13. A cross contact frame 17 is fixedly connected to the bottom of the telescopic round rod 19.

[0051] The end of the movable frame 22 extends to the surface of the slide plate 11. The inner wall of the sliding frame 23 contacts the surface of the slide plate 11. When the inclined frame 16 moves, it contacts the surface of the slewing bearing and locks it in place, thereby fixing the slewing bearing. A telescopic rod 18 and a sliding hole frame 21 are provided on the top of the inclined frame 16. The telescopic rod 18 is used to press the inclined frame 16 to prevent it from tilting upwards when moving. After the inclined frame 16 has fixed the slewing bearing, it is lifted by the hydraulic rod 25. After the slewing bearing is lifted, the electric push rod 10 retracts to move 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. This improves the convenience of the slewing bearing during transportation and prevents operators from tying steel ropes 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 slide plate 11. There are four sliding hole frames 21, which are arranged circumferentially around the cross 12.

[0052] The end of the cross contact frame 17 contacts the surface of the expansion plate 15. There are four expansion plates 15, which are arranged in a circle around the limiting frame 13. The ends of the four expansion plates 15 that are away from the limiting frame 13 are arranged away from each other.

[0053] The clamping component 4 includes an electric rod 42, the top of which is fixedly connected to the bottom of the disc 41. A mounting plate 39 is fixedly connected to the bottom of the electric rod 42. A rocker arm 32 is hinged to the inner wall of the mounting plate 39. A telescopic frame 40 is hinged to the end of the rocker arm 32 away from the mounting plate 39. An I-beam 34 is fixedly connected to the top of the telescopic frame 40. A grooved pressing rod 43 is fixedly connected to the top of the I-beam 34. An extension plate 37 is fixedly connected to the surface of the grooved pressing rod 43.

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

[0055] The end of the bracket 1 is fixedly connected to the surface of the support leg 30. After the slewing bearing is moved above the through-hole plate 31, the electric lever 42 is activated to push the mounting plate 39 upward. When the mounting plate 39 moves upward, it pushes the rocker arm 32 to move. The contact between the I-beam 34 and the inner wall of the through-hole plate 31 limits the rocker arm 32. At this time, when the mounting plate 39 moves upward, it pushes the rocker arm 32 to expand outward. When the rocker arm 32 expands, it pushes the I-beam 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, the slewing bearing is moved by the transport component 3. After the support is placed on top of the extension plate 37, the starting conveying component 3 separates from the surface of the slewing bearing and moves upward. The grooved extrusion rod 43 continues to move and contacts the slewing bearing and extrudes and fixes it, further improving the stability of the slewing bearing during quenching. The extension plate 37 can support the slewing bearing and prevent it from falling off when placed on the surface of the grooved extrusion rod 43. There are four arc plates 33, which are arranged circumferentially around the disk 41. The end of the I-beam 34 extends to the outer end of the through-hole plate 31.

[0056] The inner wall of the I-beam 34 contacts the inner wall of the through-hole plate 31. The surface of the grooved extrusion rod 43 is provided with two extension plates 37. The two extension plates 37 are symmetrically arranged with the grooved extrusion rod 43 as the center. The rectangular frame 36 is located below the rocker plate 32. The surface of the roller 35 contacts the surface of the rocker plate 32.

[0057] The lifting component 5 includes an elastic plate 52, the surface of which is rotatably connected to the inner wall of the hinge frame 55, and the end of the elastic plate 52 away from the hinge frame 55 is hinged to the surface of the rocker plate 32. A fixing frame 51 is fixedly connected to the surface of the hinge frame 55.

[0058] A cylindrical spring rod 53 is fixedly connected to the top of the fixed frame 51, and a lifting plate 54 is fixedly connected to the top of the cylindrical spring rod 53.

[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, the grooved pressing rod 43 is pushed to move towards the surface of the disc 41. At this time, the grooved pressing rod 43 will separate from the inner wall of the slewing bearing. After the grooved pressing rod 43 separates from the inner wall of the slewing bearing, the extension plate 37 will support the slewing bearing. When the grooved pressing 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 pushes the lifting plate 54 upward through the cylindrical spring rod 53 and contacts the bottom of the slewing bearing. The lifting plate 54 pushes the slewing bearing upward. At this time, the conveying component 3 is activated to move downward. The bottom of the inclined frame 16 contacts the top of the lifting plate 54 and slides on the top of the lifting plate 54 so that the inclined frame 16 can lift the slewing bearing. At this time, the grooved pressing rod 43 is pushed to move away from the end of the disc 41. After the grooved pressing rod 43 moves to the surface of the slewing bearing, the slewing bearing is placed on the top of the extension plate 37. Then, the grooved pressing rod 43 is pushed to move towards the surface of the disc 41. At this time, the grooved pressing rod 43 can press and fix the surface of the slewing bearing, further improving the convenience of changing the clamping position of the slewing bearing. The end of the elastic plate 52 away from the hinge frame 55 is inclined downward. There is a gap between the surface of the lifting plate 54 and the surface of the through-hole plate 31.

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

[0061] S1: A conveying component 3 is provided on the surface of the right-angle plate 2. When the conveying component 3 is activated to move downward, the conveying 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 conveying component 3 contacts the surface of the slewing bearing, the slewing bearing can be moved to the top of the clamping component 4 through the conveying component 3.

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

[0063] S3: When the rocker 32 expands, it will push the I-beam 34 to move away from the outer end of the disc 41. After the extension plate 37 moves to the bottom of the slewing bearing, the slewing bearing is placed on the top of the extension plate 37 by the transport component 3. Then the transport component 3 is activated to separate from the surface of the slewing bearing and move upward. The grooved extrusion rod 43 continues to move and contact the slewing bearing and extrudes and fixes it.

[0064] S4: When the grooved extrusion rod 43 moves toward 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 spring rod 53 and contact the bottom of the slewing bearing. The lifting plate 54 will push the slewing bearing to move upward.

[0065] In use, the electric actuator 10 is activated to push the movable frame 22 to move on the surface of the right-angle plate 2. As the movable frame 22 moves, it pushes the sliding frame 23 to slide on the surface of the slide plate 11. The slider 24 inside the sliding frame 23 slides along the inner wall of the slide plate 11, supporting the sliding frame 23 and improving its load-bearing capacity and stability. The hydraulic rod 25 is activated to push the electric telescopic rod 20 downwards. When the bottom of the inclined frame 16 contacts the ground, the electric telescopic rod 20 extends downwards. As the electric telescopic rod 20 moves downwards, it compresses the expansion plate 15. The inclined frame 16 at the bottom of the expansion plate 15 limits its movement. At this point, the expansion plate 15, under pressure, pushes the inclined frame 16 against each other. When the slewing bearing moves away from the surface, the inclined frame 16 contacts and locks onto it, thus fixing the slewing bearing. A telescopic rod 18 and a sliding hole bracket 21 are installed at the top of the inclined frame 16. The telescopic rod 18 presses against the inclined frame 16 to prevent it from tilting upwards during movement. After the inclined frame 16 has fixed the slewing bearing, it is lifted using a hydraulic rod 25. Once lifted, the electric actuator 10 retracts, moving the slewing bearing to the top of the clamping component 4 and securing it there. This improves the ease of transporting the slewing bearing and prevents operators from getting burned by tying steel cables to the surface of the slewing bearing. After the slewing bearing is moved above the through-hole plate 31… The electric lever 42 is activated to push the mounting plate 39 upward. As the mounting plate 39 moves upward, it pushes the rocker arm 32. The contact between the I-beam 34 and the inner wall of the through-hole plate 31 limits the rocker arm 32. At this time, the upward movement of the mounting plate 39 pushes the rocker arm 32 outward. As the rocker arm 32 expands, it pushes the I-beam 34 away from the outer end of the disc 41. When the extension plate 37 moves to the bottom of the slewing bearing, the transport component 3 places the slewing bearing on top of the extension plate 37. The transport component 3 is then activated to separate from the surface of the slewing bearing and moves upward. The grooved pressing rod 43 continues to move, contacting the slewing bearing and pressing it to fix it, further improving the stability of the slewing bearing during quenching. The extension plate 37 can... The slewing bearing is supported to prevent it from falling off when placed on the surface of the grooved pressing rod 43. When the clamping position of the slewing bearing needs to be adjusted, the grooved pressing rod 43 is pushed towards the surface of the disc 41. At this time, the grooved pressing rod 43 will separate from the inner wall of the slewing bearing. After the grooved pressing rod 43 separates from the inner wall of the slewing bearing, the extension plate 37 will support the slewing bearing. When the grooved pressing 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 upward through the cylindrical spring rod 53 and contact the bottom of the slewing bearing. The lifting plate 54 will push the slewing bearing upward.
