DETAILED DESCRIPTION

[0021] 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.

[0022] Example 1

[0023] like Figure 1-4 As shown, a crane pulley for a crane in the figure includes an outer fixing plate 1 and a lifting mechanism arranged inside the outer fixing plate 1, and the lifting mechanism includes an adjusting assembly and a pulley assembly;

[0024] The adjustment assembly includes an adjustment slot 2, a fixing bolt 3, an inner frame 5, a fastening bolt 8 and a screw 9. The adjustment slot 2 is opened on the front and rear sides of the outer fixing plate 1, and the fixing bolt 3 is installed inside the adjustment slot 2. The inner frame 5 is installed inside the outer fixing plate 1, and the fastening bolt 8 is installed on the side of the inner frame 5, and the screw 9 is installed on the side of the fastening bolt 8.

[0025] The pulley assembly includes an inner cavity 4 , a pulley mechanism 6 and a fixing groove 7 . The inner cavity 4 is opened inside the outer fixing plate 1 , and the pulley mechanism 6 is installed inside the inner frame 5 , and the fixing groove 7 is installed inside the pulley mechanism 6 .

[0026] The inner frame 5 forms a translation structure with the outer fixing plate 1 through the cooperation between the fixing bolt 3 and the adjusting groove 2, and the inner frames 5 are symmetrical about the center line of the outer fixing plate 1, so that the inner frame 5 can move inside the adjusting groove 2 through the fixing bolt 3 and translate with the outer fixing plate 1, so that the distance between the inner frames 5 can be adjusted, thereby adjusting the distance between the inner pulleys 605, making the device more flexible and convenient to use.

[0027] The fixing groove 7 and the inner frame 5 are fixed to each other, and the fixing groove 7 is a hollow structure, so that during use, the fixing groove 7 can support the entry and exit of the cable used by the device, facilitate the support of the cable, thereby facilitating the use of the device, and can also adjust the angle of the cable inside the device.

[0028] The inner frame 5 forms a detachable structure with the outer fixing plate 1 through the cooperation between the fastening bolts 8 and the screw rods 9, so that when the inner frame 5 is adjusted at an angle inside the outer fixing plate 1 through the adjustment grooves 2, the inner frame 5 can be supported and fixed by the screw rods 9 and the fastening bolts 8, thereby preventing the inner frame 5 from tilting inside the device and affecting the use of the device.

[0029] Example 2

[0030] like Figure 3 As shown, this embodiment further illustrates Example 1, the pulley mechanism 6 includes an end plate 601, a rotating shaft 602, a connecting rod 603, a support plate 604 and an inner pulley 605, the rotating shaft 602 is installed inside the end plate 601, and the connecting rod 603 is installed above the rotating shaft 602, the support plate 604 is installed at the bottom of the end plate 601, and the inner pulley 605 is installed between the end plates 601.

[0031] The inner pulley 605 forms a rotating structure with the end plate 601 through the rotating shaft 602, and the inner pulleys 605 are symmetrical to each other, so that the inner pulley 605 can rotate inside the device through the rotating shaft 602, so as to support the cable and facilitate the use of the crane to lift the cable.

[0032] During use: first, the user installs the device, and then the inner frame 5 moves inside the adjusting groove 2 through the fixing bolt 3 and translates with the outer fixing plate 1, so as to adjust the distance between the inner frames 5, thereby adjusting the distance between the inner pulleys 605, so that the device is more flexible when in use and convenient to use. When the inner frame 5 is adjusted at an angle inside the outer fixing plate 1 through the adjusting groove 2, the inner frame 5 can be supported and fixed by the screw 9 and the fastening bolt 8 to prevent the inner frame 5 from tilting inside the device and affecting the use of the device. Then, during use, the fixing groove 7 supports the entry and exit of the cable used by the device, which is convenient for supporting the cable, thereby facilitating the use of the device and adjusting the angle of the cable inside the device. At the same time, the inner pulley 605 rotates inside the device through the rotating shaft 602 to support the cable, which is convenient for the crane to lift the cable.
