[0001] The utility model relates to the field of bearing hoisting tools, in particular to a tool for horizontally hoisting a bearing. Background Art

[0002] The bearings of the combined gearbox are large in size and heavy, making them difficult to carry manually. For example, the free-side bearing of the output shaft of the 5H combined gearbox has dimensions of 320*480*121 and weighs 78.5kg. The 24068CA / W33 / C3 shaft of the 3H combined gearbox weighs approximately 140kg. During daily installation, at least multiple people are required to carry it simultaneously.

[0003] In addition, the shaft and bearings are interference-fitted, and the bearings need to be heated to above 120°C before installation. At the same time, the bearings on overly long gear shafts need to be installed upright, which poses a risk of burns and slipping during installation.

[0004] Common lifting methods such as passing the sling through the inner ring of the bearing, wrapping the sling around the outer ring of the bearing, and tying the bearing with thin wire are not advisable due to poor safety performance during the lifting process or the limitation that the bearing needs to be installed upright. Therefore, in the process of maintaining the combined gearbox, how to choose the appropriate lifting and assembly tools to eliminate the safety hazards of burns and injuries when assembling bearings and improve work efficiency is an urgent problem to be solved.

[0005] How to lift the bearing stably and safely is the problem to be solved. Utility Model Content

DETAILED DESCRIPTION

[0025] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0026] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] like Figure 1 and Figure 2 and Figure 3 As shown, a tool for horizontally lifting a bearing includes a first lifting rod 1, a second lifting rod 2, a lifting ring 3 and a cross bar 4, wherein the lifting ring 3 is used for lifting in conjunction with other equipment.

[0029] The first boom 1 and the second boom 2 are hingedly arranged on the cross bar 4, and the first boom 1 and the second boom 2 can rotate on the cross bar 4. In this example, the first boom 1 and the second boom 2 are vertically arranged, and the cross bar 4 is located on the upper part of the first boom 1 and the second boom 2. The cross bar 4 passes through the lifting ring 3. The lifting ring 3 in this example is an open ring, and the upper part of the first boom 1 and the second boom 2 are both located in the lifting ring 3.

[0030] A first support plate 11 is provided on the first boom 1 and is arranged at the bottom of the first boom 1 . A second support plate 21 is provided on the second boom 2 and is arranged at the bottom of the second boom 2 . The first support plate 11 and the second support plate 21 are arranged opposite to each other.

[0031] When the first boom 1 and the second boom 2 rotate in opposite directions, the first pallet 11 and the second pallet 21 can approach and move away from each other. When the first pallet 11 and the second pallet 21 are close to each other, the first pallet 11 and the second pallet 21 are used to jointly support the bearing 6, lift the bearing 6 through the lifting ring 3, and transport the bearing 6 to another position. Then the first pallet 11 and the second pallet 21 move away from each other, put down the bearing 6, and achieve the purpose of transporting the bearing 6.

[0032] A spring 5 is provided between the first hanger 1 and the second hanger 2, and both ends of the spring 5 are connected to the first hanger 1 and the second hanger 2 respectively. The spring 5 maintains a set distance between the first hanger 1 and the second hanger 2. The spring 5 provides a buffering effect between the first support plate 11 and the second support plate 21, so that the bearing 6 is not easy to fall off.

[0033] There is a distance between the first support plate 11 and the second support plate 21. Because the bearing 6 is placed horizontally in this example, and the middle of the bearing 6 is hollow for installation, the distance between the first support plate 11 and the second support plate 21 should be greater than the diameter of the middle of the bearing 6. This facilitates the installation of the bearing 6. Otherwise, the first support plate 11 and the second support plate 21 block the hollow part in the middle of the bearing 6, which is not conducive to installation.

[0034] A first guard plate 13 and a second guard plate 14 are respectively provided on both sides of the first support plate 11, and a third guard plate 23 and a fourth guard plate 24 are respectively provided on both sides of the second support plate 21. The first guard plate 13 and the third guard plate 23 are arranged opposite to each other, and the second guard plate 14 and the fourth guard plate 24 are arranged opposite to each other. When the first support plate 11 and the second support plate 21 jointly support the bearing 6, in order to prevent the bearing 6 from tilting on the first support plate 11 and the second support plate 21, the first guard plate 13 and the second guard plate 14 abut and clamp the outer periphery of the bearing 6, and the third guard plate 23 and the fourth guard plate 24 also abut and clamp the outer periphery of the bearing 6 on the other side. The two sides of the bearing 6 are symmetrically abutted and clamped, so that the two sides of the bearing 6 are evenly stressed, preventing the bearing 6 from tilting during transportation.

[0035] The first suspension rod 1 is bent to form a first curved portion 12 , and the second suspension rod 2 is bent to form a second curved portion 22 . The first curved portion 12 and the second curved portion 22 are spaced apart from each other, and two ends of the spring 5 are connected to the first curved portion 12 and the second curved portion 22 .

[0036] A first reinforcement bar 7 is provided on the first hanger 1, and a second reinforcement bar 8 is provided on the second hanger 2. The first reinforcement bar 7 can bend and extend along with the first hanger 1, and the second reinforcement bar 8 can bend and extend along with the second hanger 2. The first reinforcement bar 7 is shorter than the first hanger 1, and the second reinforcement bar 8 is shorter than the second hanger 2. In this way, when the first hanger 1 and the second hanger 2 rotate in opposite directions, the top of the first reinforcement bar 7 will not collide with the top of the second reinforcement bar 8.

[0037] The above embodiments are only for illustrating the technical concept and features of the present invention. Their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the scope of protection of the present invention.
