[0017] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0018] like Figure 1-4 As shown, this utility model provides a top grab for disassembling pulleys, which mainly includes: a base 110, a bracket 120 and a pressure plate 130.

[0019] Two brackets 120 are symmetrically installed at both ends of the top of the base 110. The two brackets 120 are arranged in parallel and are vertically perpendicular to the base 110. Two guide holes 120a are correspondingly opened on the brackets 120. The two guide holes 120a are symmetrically arranged and their length direction is parallel to the base 110, that is, the length direction of the guide holes 120a is parallel to the length direction of the brackets 120.

[0020] Two pressure plates 130 are spaced apart along the length of the bracket 120. Each pressure plate 130 includes a crossbeam 131 and two support arms 132. The upper ends of the two support arms 132 are symmetrically fixed to both ends of the crossbeam 131, and the support arms 132 are perpendicular to the crossbeam 131. Both the crossbeam 131 and the support arms 132 are made of steel plates, and their width and thickness are the same. The pressure plate 130 has an overall U-shaped structure. The lower ends of the two support arms 132 are respectively connected to guide holes 120a and can move along the length of the guide holes 120a.

[0021] In this embodiment, the bracket 120 includes a vertical plate 121 and a top plate 122. The bottom of the vertical plate 121 is fixedly disposed at one end of the top of the base 110 and is perpendicular to the base 110; one end of the top plate 122 is fixedly connected to the top of the vertical plate 121, and the top plate 122 is disposed parallel to the base 110. A guide hole 120a is formed on the vertical plate 121.

[0022] As a preferred embodiment, the bracket 120 further includes two first reinforcing plates 123, which are symmetrically arranged at both ends of the upright plate 121 and connected between the upright plate 121 and the top plate 122. The top of the first reinforcing plate 123 is fixedly connected to the top plate 122, and one side of the first reinforcing plate 123 is fixedly connected to the upright plate 121.

[0023] In this embodiment, the bottom of the first reinforcing plate 123 is fixedly connected to the top of the base 110. The upright plate 121, the top plate 122, and the first reinforcing plate 123 are all made of steel plates of the same thickness. The connections between the upright plate 121, the top plate 122, the first reinforcing plate 123, and the base 110 are all fixedly connected by welding.

[0024] In this embodiment, the support arm 132 is connected to the guide elongated hole 120a by bolts 133. A nut 134 is installed on the bolt 133. Loosening the nut 134 allows the bolt 133 to slide along the length direction of the guide elongated hole 120a, thereby driving the support arm 132 to move; tightening the nut 134 can fix the support arm 132 in the guide elongated hole 120a.

[0025] As a preferred embodiment, the support arm 132 is provided with multiple bolt connection holes 132a, which are spaced apart along the length of the support arm 132. Bolts 133 can be selectively connected to any bolt connection hole 132a, aligning different positions of the support arm 132 with the position of the guide elongated hole 121, thereby changing the height of the upright plate 121 to accommodate different types of pulleys.

[0026] In this embodiment, the base 110 includes a main board 111 and two end plates 112, which are vertically connected to both ends of the main board 111. The base 110 has an overall I-shaped structure. Two brackets 120 are respectively fixed to both ends of the main board 111 and located inside the two end plates 112. The outer side of the upright plate 121 of the bracket 120 abuts against the inner side of the corresponding end plate 112 and is fixedly connected to it. The end plates 112 further strengthen the fixation of the upright plates 121.

[0027] As a preferred embodiment, the base 110 further includes: a second reinforcing plate 113, which is fixedly connected to the bottom of the main board 111, the top of the second reinforcing plate 113 is connected to the main board 111, and the two ends of the second reinforcing plate 113 are respectively fixedly connected to two end plates 112.

[0028] In this embodiment, the base 110 is made directly from an I-beam. The second reinforcing plate 113 is fixedly connected to the bottom of the I-beam by welding.

[0029] The pulley for disassembling pulleys provided by this utility model needs to be used in conjunction with a jack. When using it, place the jack on the main plate of the base 110, place the pulley on the two brackets 120, move the two pressure plates 130 to the appropriate position, and fix the pressure plates 130 by tightening the nuts 134, so that the pulley is fixed on the brackets 120 by the pressure plates 130. Use the jack to push the inner shaft of the pulley from the bottom, apply pressure to push out the inner shaft of the pulley, and realize the disassembly of the pulley.

[0030] The top grab for disassembling pulleys provided by this utility model fixes the pulleys by cooperating with the pressure plate 130 and the bracket 120. The pressure plate 130 has a large contact area with the pulley and will not damage the pulleys; thus, it can achieve quick disassembly of the pulleys.

[0031] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made.
