[0027] Such as Figures 1 to 4As shown in the figure, when the equipment with a winch pressurization method is working, multiple sets of pulleys 11 need to be arranged on the mast to guide or change the path of the wire rope. For example, construction machinery such as a rotary drilling rig or a crane. The pulley components are installed on the mast of the rotary drilling rig or the mast of the crane. The pulley components are part of the winch pressurization system. The pulley components include a pulley 11, a mounting shaft 12, and a mounting bracket 13. The mounting bracket 13 includes a first mounting portion 131 and a second mounting portion 132 arranged oppositely, and a third mounting portion 133 and a fourth mounting portion 134 arranged oppositely. The first mounting portion 131 and the second mounting portion 132 are respectively fixedly connected to the third mounting portion 133 and the fourth mounting portion 134. The first mounting portion 131 is provided with a first mounting hole 101, and the second mounting portion 132 is provided with a second mounting hole 102. The pulley 11 is arranged between the first mounting portion 131 and the second mounting portion 132. The mounting shaft 12 is sequentially arranged through the first mounting hole 101, the pulley 11, and the second mounting hole 102. The third mounting portion 133 is fixedly connected to the mast through a first fastener, and the fourth mounting portion 134 is fixedly connected to the mast through a second fastener. In this embodiment, an installation area is formed between the first mounting portion 131, the second mounting portion 132, the third mounting portion 133, and the fourth mounting portion 134. The pulley 11 is arranged in the installation area. Among them, the third mounting portion 133 and the fourth mounting portion 134 are preferably in a plate-like or block-like structure. The third mounting portion 133 is provided with at least two first connection holes 105, and the mast is provided with first threaded holes matching the first connection holes 105. The first fastener passes through the first connection holes 105 and the first threaded holes to be fixedly connected to the mast. The fourth mounting portion 134 is provided with at least two second connection holes 106. The second fastener passes through the second connection holes 106 to be fixedly connected to the mast. The fourth mounting portion 134 is provided with second threaded holes matching the second connection holes 106. The second fastener passes through the second connection holes 106 and the second threaded holes to be fixedly connected to the mast.

[0028] The pulley component of the present utility model assembles the pulley 11, the mounting shaft 12, and the mounting bracket 13 into an integral structure. It is not necessary to pre-process the mounting holes for the pulley 11 shaft on the mast. During installation, the third mounting portion 133 is fixed on the mast through a first fastener, and the fourth mounting portion 134 is fixed on the mast through a second fastener, realizing the fixed connection between the pulley component and the mast. By connecting the pulley component as a whole to the mast, compared with the split installation of the pulley 11 and the mast in the prior art, the installation space required for the pulley component is smaller, the processing requirements are lower, the installation and replacement are convenient, and the problem that some models cannot be equipped with a winch pressurization system due to space limitation is solved.

[0029] As Figure 2 and Figure 3As shown, the mounting frame 13 includes a first limiting plate 135 and a second limiting plate 136, which are arranged on a side of the first mounting portion 131 away from the pulley 11, and the first limiting plate 135 and the second limiting plate 136 are respectively fixedly connected to the first mounting portion 131, and the mounting shaft 12 is provided with a first limiting groove 103 and a second limiting groove 104 which are arranged opposite to each other, at least a part of the first limiting plate 135 is arranged in the first limiting groove 103, and at least a part of the second limiting plate 136 is arranged in the second limiting groove 104, and the first limiting plate 135 and the second limiting plate 136 provide axial fixation for the mounting shaft 12, so as to prevent the mounting shaft 12 from rotating with the pulley 11 when the pulley 11 rotates, and also prevent the mounting shaft 12 from loosening during use. Among them, the first limiting plate 135 is rectangular or arc-shaped, and the second limiting plate 136 is rectangular or arc-shaped, but is not limited thereto.

[0030] like Figure 1 and Figure 2 As shown, the first mounting portion 131 includes a first connecting segment 1311, a second connecting segment 1312 and a third connecting segment 1313 which are fixedly connected in sequence, the second connecting segment 1312 is annular, the second connecting segment 1312 is arranged between the first connecting segment 1311 and the third connecting segment 1313, the first mounting hole 101 is arranged in the second connecting segment 1312, the first limiting plate 135 and the second limiting plate 136 are respectively fixedly connected to the second connecting segment 1312, and the fixed connection method is preferably fixed by bolts or screws.

[0031] like Figure 3 As shown, the roller skate component is also provided with a bearing 14, and the mounting shaft 12 is arranged through the bearing 14, and the bearing 14 is arranged between the mounting shaft 12 and the pulley 11, which can reduce the friction coefficient between the mounting shaft 12 and the pulley 11, ensure the rotation accuracy of the mounting shaft 12, and reduce energy consumption.

[0032] like Figure 3 As shown, the mounting shaft 12 is provided with a first oil passage 107 and a second oil passage 108. The first oil passage 107 is arranged along the axial direction of the mounting shaft 12, and the second oil passage 108 is designed and arranged along the radial direction of the mounting shaft 12. One end of the first oil passage 107 is connected to the oil cup, and the other end of the first oil passage 107 is connected to the second oil passage 108. The oil in the oil cup flows to the bearing 14 through the first oil passage 107 and the second oil passage 108, thereby reducing the friction between the bearing 14 and the mounting shaft 12.

[0033] The installation space required for the roller skating component of the present utility model is small, which can solve the problem that the installation space of small-sized construction machinery is limited and the winch pressurization system cannot be installed. The roller skating component can be fixedly connected to the mast through bolts, without welding vertical plates on the mast and setting holes for the installation shaft 12, with lower processing requirements, convenient and fast installation and replacement, and improved installation speed of the roller skating component. In addition, using an integral roller skating component, it can be directly installed and disassembled during installation and replacement, greatly improving the installation efficiency.
