Description

Technical Field

[0001] The utility model relates to the technical field of bearing hangers, in particular to a large-scale bearing hanger. Background Art

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy.

[0003] Through patent search, it was found that a large bearing assembly hanger with publication number CN209583404U greatly facilitates the lifting and movement of large bearings during assembly through a special hanger for heating large bearings. However, its support hook is located on the bottom side of the bearing, and a special load-bearing component is required when placing the bearing. When the bearing needs to be placed on a plane, its support hook will first contact the plane, and the bearing cannot be placed directly on the plane, which is relatively inconvenient to use. For this reason, we propose a large bearing hanger to solve or improve the above problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a large bearing hanger to solve the problems mentioned in the above background.

[0005] The utility model provides the following technical solutions: it includes a hanging plate, a mounting groove opened on the top of the hanging plate, a plurality of mounting grooves are arranged in a circle on the top of the hanging plate, a hanging claw inside the mounting groove is movably inserted into the hanging claw through a rotating shaft, a support hook is rotatably installed at the bottom of the hanging claw through the rotating shaft, a limit block is fixed to the top of the support hook, the limit block is inserted into the inside of the hanging claw, a support frame is fixed to the surface of the hanging claw, a limit rod passes through the inside of the support frame and is inserted into the inside of the hanging claw and the limit block, and a spring is sleeved on the surface of the limit rod.

[0006] Furthermore, the surface of the limiting rod is fixed with a limiting plate at a position on one side of the hanging claw, one end of the spring contacts the surface of the limiting plate, and the other end contacts the surface of the supporting frame.

[0007] Furthermore, a handle is fixed to one end of the limiting rod, and a surface of the handle contacts a surface of the supporting frame.

[0008] Furthermore, the number of the hanging claws is the same as the number of the mounting slots, and through holes are provided on the surfaces of the hanging claws, and the connecting rings are inserted between the through holes of several groups of hanging claws.

[0009] Furthermore, the edge of the position where the limiting plug block is inserted at the bottom of the hanging claw is designed as a curved surface.

[0010] Furthermore, one side surface of the limiting plate fixed to the surface of the limiting rod contacts the surface of the hanging claw.

[0011] Compared with the prior art, the utility model has the following beneficial effects: by arranging the support hook and the limit rod, the limit rod can limit the position of the support hook when the support hook supports the bottom of the bearing, thereby preventing the support hook from rotating itself when supporting the bearing; when the bearing needs to be placed on a certain plane, the support hook is first moved to the top side of the plane where it needs to be placed. At this time, the limit rod is pulled to disengage the limit rod from the inside of the limit plug, so that the support hook can rotate around the rotating shaft. At this time, the bearing will slide downward along the surface of the support hook and fall to the top of the plane where it needs to be placed, thereby directly placing the bearing on the plane, which is relatively convenient to use.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-4, including a hanging plate 1, a mounting groove 2 opened on the top of the hanging plate 1, and a plurality of groups of mounting grooves 2 are arranged in a circle on the top of the hanging plate 1, and hanging claws 3 are movably inserted into the mounting grooves 2 through a rotating shaft, and the number of hanging claws 3 is the same as the number of mounting grooves 2 and a through hole is opened on the surface of the hanging claws 3, and a connecting ring 4 is inserted between the through holes of the plurality of groups of hanging claws 3. The structure, use method, effect and function of the hanging plate 1, the mounting groove 2, the hanging claws 3 and the connecting ring 4 are the same as those in the comparative document, and will not be described in detail here. The supporting hook 5 is rotatably installed at the bottom of the hanging claw 3 through a rotating shaft, and the supporting hook 5 can rotate around one end of the rotating shaft. The top of the supporting hook 5 is fixed with anti-slip silicon The rubber pad can protect the surface of the bearing by the anti-slip silicone pad to prevent the surface of the support hook 5 from direct contact and friction with the surface of the bearing when supporting the bearing, causing damage to the bearing surface. The limit block 8 is fixed to the top of the support hook 5. When the support hook 5 rotates, it will drive the fixed limit block 8 to rotate. The limit block 8 is inserted into the inside of the lifting claw 3. The edge of the position where the limit block 8 is inserted at the bottom of the lifting claw 3 is designed as an arc surface. The arc surface design can guide the limit block 8 when the support hook 5 rotates and drives the limit block 8 to be inserted into the inside of the lifting claw 3, so that the limit block 8 can slide into the inside of the lifting claw 3 and reduce the collision between the limit block 8 and the inner surface of the lifting claw 3.

[0019] The support frame 6 is fixed to the surface of the hanging claw 3, and the limit rod 9 passes through the interior of the support frame 6 and is inserted into the interior of the hanging claw 3 and the limit plug block 8. When the limit rod 9 is inserted into the interior of the hanging claw 3 and the limit rod 9, the limit rod 9 can limit the position of the limit plug block 8 through the hanging claw 3 to prevent the limit plug block 8 from escaping from the interior of the hanging claw 3, thereby limiting the position of the support hook 5 through the limit plug block 8 to prevent the support hook 5 from rotating around one end of the rotating shaft. A handle is fixed to one end of the limit rod 9, and the surface of the handle contacts the surface of the support frame 6. The support frame 6 can limit the position of the limit rod 9 to prevent the limit rod 9 from escaping from the interior of the support frame 6 from the side close to the hanging claw 3. By pulling the handle, the fixed limit rod 9 can be driven to move to the side away from the hanging claw 3. The spring 7 is sleeved on the surface of the limit rod 9, and the surface of the limit rod 9 is located at the position of the limit plate on one side of the hanging claw 3. The positioning plate can limit the position of the limit rod 9, preventing the limit rod 9 from escaping from the inside of the support frame 6 from the side away from the lifting claw 3. At the same time, the limit plate can also limit the limit rod 9 from escaping from the inside of the lifting claw 3. When one end of the limit rod 9 is about to escaping from the inside of the lifting claw 3, the surface of the limit plate will contact the surface of the support frame 6, thereby limiting the limit rod 9 from continuing to move to the side away from the lifting claw 3. The limit plate fixed on the surface of the limit rod 9 has one side surface in contact with the surface of the lifting claw 3, thereby preventing the limit rod 9 from being excessively inserted into the inside of the lifting claw 3. One end of the spring 7 contacts the surface of the limit plate, and the other end contacts the surface of the support frame 6. When the limit rod 9 moves, it will drive the limit plate fixed on the surface to move. When the limit plate moves, it will squeeze the contacting spring 7, causing the spring 7 to deform. When there is no external force interference, the spring 7 will push the limit plate to move, thereby causing the limit plate to drive the limit rod 9 to move.

[0020] Working principle: when the bearing needs to be hoisted, the lifting platform 1 is moved to the top side of the bearing to be hoisted through the lifting device. At this time, the lifting platform 1 is moved downward, and the lower end of the lifting claw 3 expands outward. When the support hook 5 installed by the rotation at the bottom of the lifting claw 3 moves to the bottom edge of the bearing, the lifting platform 1 is pulled upward to clamp and hoist the bearing through the lifting claw 3 and the support hook 5. Since the structure, use method, effect and function of the lifting platform 1, installation groove 2, lifting claw 3 and connecting ring 4 are the same as those in the comparative document, they will not be described in detail here. When the bearing needs to be placed on a certain plane, first move the support hook 5 to the top side of the plane where it needs to be placed. At this time, pulling the limit rod 9 to disengage the limit rod 9 from the inside of the limit plug 8 can make the limit rod 9 no longer limit the position of the limit plug 8, so that the support hook 5 can rotate around the rotating shaft. When the support hook 5 rotates, its surface will contact the plane, so that the top of the support hook 5 is inclined and forms a certain inclined surface. At this time, slowly move the hanging plate 1 upwards so that the hanging plate 1 drives the installed hanging claw 3 and the support hook 5 fixed at the bottom of the hanging claw 3 to move, so that the support hook 5 can rotate slightly while moving, so that the bearing slowly falls along the surface of the support hook 5 and finally falls to the top of the plane where it needs to be placed, so that the bearing can be directly placed on the plane, which is relatively convenient to use.
