Description

Technical Field

[0001] The utility model relates to the technical field of bearing hoisting, in particular to a special hoisting device for bearings. Background Art

[0002] The weight of the four-row tapered roller bearing in the work roll bearing seat is 183KG or more, and the bearing has no hanging point. During the assembly of the bearing seat, the bearing installation and disassembly process adopts the method of manual handling, and the bearing is disassembled and assembled in sequence. The process is extremely inconvenient and has the following main disadvantages:

[0003] 1. The bearing raceway surface is easily damaged during installation, and there is a risk of the bearing damaging the box;

[0004] 2. The bearing is heavy and has a small gap with the bearing seat. Manual disassembly and handling of the bearing may easily lead to safety accidents such as finger pinching.

[0005] 3. The assembly precision between the bearing and the bearing seat is high, and the assembly gap is very small. Manual disassembly and placement without levelness can easily cause the bearing and the bearing seat to get stuck, affecting the normal assembly of the bearing seat. Utility Model Content

[0006] The purpose of the utility model is to provide a special hanger for bearings to solve the problems raised in the above background technology.

[0007] To achieve the above object, the utility model provides the following technical solutions: a bearing-specific hanger, comprising a base rod, the lower end of the base rod having an integrally formed threaded head, a pressing plate being provided on the upper surface of the base rod, and a positioning plate being screwed on the lower surface of the threaded head;

[0008] The surface of the positioning plate is provided with a plurality of fixing holes, in which fasteners are provided, and a clamping plate is installed on the fasteners;

[0009] The positioning plate and the clamping plate clamp the bearing, and the clamping plate supports the inner ring of the bearing to limit the sliding of the bearing. During hoisting, the bearing has higher stability and is safer.

[0010] Furthermore, a lifting ring is fixedly connected to the upper end of the base rod, and the lifting ring is used to lift the base rod. The lifting ring is hung with a steel hook, which is convenient in the process of moving the bearing.

[0011] Furthermore, a thickened plate is fixedly connected to the middle of the surface of the positioning plate, and the thickened plate is screwed to the base rod to improve the stability of the connection between the positioning plate and the base rod and prevent the positioning plate from being separated from the base rod due to rotation.

[0012] Furthermore, two first suspension rods are screwed on the surface of the thickened plate, and second suspension rods are screwed on the upper surfaces of the left and right clamping plates. Without using lifting rings, the two first suspension rods and the two second suspension rods can be used to lift the bearing, which is more flexible to use.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) Place the bearing on the positioning plate, adjust the positions of the two clamping plates to support the inner ring of the bearing, screw the base rod to the positioning plate, and then use the lifting ring to lift the bearing. Only one person is needed to complete the disassembly and assembly of this type of bearing, and the disassembly and assembly efficiency is also higher.

[0015] (2) Use bearing hoists to carry bearings, eliminating the need to carry them by hand. This avoids direct contact between people and bearings and the risk of hand injuries.

[0018] 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.

[0019] Example:

[0020] See also Figure 1 The utility model provides a technical solution: a bearing-specific hanger, comprising a base rod 2, the lower end of the base rod 2 has an integrally formed threaded head 10, a pressing plate 5 is provided on the upper surface of the base rod 2, and a positioning plate 3 is screwed to the lower surface of the threaded head 10;

[0021] like Figure 1 As shown, the bearing comprises a bearing outer ring 6, a bearing inner ring 11, a tapered roller 12, and a bracket 15. The bracket 15 is mounted on the outer surface of the bearing inner ring 11. The tapered roller 12 is rotatably connected to the bracket 15, so that the tapered roller 12 is placed between the bearing outer ring 6 and the bearing inner ring 11. The tapered roller 12 supports the bearing outer ring 6 and enables the bearing outer ring 6 to rotate smoothly.

[0022] The positioning plate 3 and the threaded head 10 can be separated by twisting the base rod 2, so that the bearing can be placed on the positioning plate 3 for positioning, and then the threaded head 10 is screwed with the positioning plate 3, so that the pressure plate 5 presses the bearing outer ring 6 and the bearing inner ring 11 of the bearing;

[0023] The surface of the positioning plate 3 is provided with a plurality of fixing holes, in which fasteners are provided, and a clamping plate 4 is installed on the fasteners. The fixing holes at different positions can be adjusted in position by cooperating with the fasteners, which is more compatible with bearings of different sizes and is convenient for hoisting bearings of different sizes.

[0024] The positioning plate 3 and the clamping plate 4 clamp the bearing, and the clamping plate 4 supports the inner ring 11 of the bearing to limit the sliding of the inner ring 11 of the bearing, thereby preventing sliding and shaking problems from occurring during the movement of the bearing.

[0025] In this embodiment, if Figure 1 As shown, a lifting ring 1 is fixedly connected to the upper end of the base rod 2, and the lifting ring 1 is used to lift the base rod 2. By hanging the lifting ring 1 with a steel hook, the base rod 2, the positioning plate 3, and the bearing can be lifted together.

[0026] In this embodiment, the fasteners include bolts 8 and nuts 7. When the position of the card plate 4 needs to be adjusted, just loosen the nuts 7 and insert the bolts 8 into the appropriate fixing holes. An arc-shaped opening can also be set on the positioning plate 3 as needed. One corner of the card plate 4 is fixed with bolts 8 and nuts 7, and the other corner of the card plate 4 is aligned with the arc-shaped opening. Another bolt 8 and nut 7 are used to cooperate with the arc-shaped opening to fix the card plate 4. The position of the card plate 4 can be rotated to adjust the card plate 4 to better adjust the card plate 4 against the inner ring 11 of the bearing.

[0027] In this embodiment, a thickened plate 9 is fixedly connected to the middle of the surface of the positioning plate 3, and the thickened plate 9 is screwed to the threaded head 10. The thickened plate 9 increases the screw connection area between the positioning plate 3 and the threaded head 10, ensuring that the connection between the threaded head 10 and the positioning plate 3 is more stable.

[0028] In this embodiment, two first suspension rods 14 are screwed onto the surface of the thickened plate 9, and second suspension rods 13 are screwed onto the upper surfaces of the left and right clamping plates 4. When the lifting ring 1 and the base rod 2 are not used, the lifting equipment can be connected to the first suspension rod 14 and the second suspension rod 13, and the bearing can also be lifted.

[0029] Specifically, when in use, screw the base rod 2 to separate the threaded head 10 from the positioning plate 3, then loosen the nut 7 to adjust the position of the clamping plate 4, put the bearing on the positioning plate 3, adjust the positions of the two clamping plates 4 to support the inner ring 11 of the bearing, fix the position of the bearing, tighten the bolts 8 and the nuts 7 to lock the clamping plates 4 to prevent movement, thereby fixing the bearing, then align the threaded head 10 with the screw hole of the positioning plate 3 and rotate the base rod 2 to screw the positioning plate 3 until the pressure plate 5 presses the bearing, then use a crane to connect it to the lifting ring 1, lift the bearing with the crane, align it with the bearing seat and put it in, and the bearing assembly process is safer and faster.
