Embodiment 1
[0036] Such as figure 1 As shown, the moving device of the hoisting assembly in this embodiment includes a fixed beam 1 , a hydraulic cylinder 3 and a connecting assembly 2 . The connecting component 2 is socketed with the fixed beam 1 and can slide along the fixed beam 1 to drive the lifting component 6 to move; one end of the hydraulic cylinder 3 is fixedly connected with the fixed beam 1, and the other end is fixedly connected with the connecting component 2 to drive the connecting component 2 slides relative to the fixed beam 1.
[0037] Such as figure 1 As shown, the fixed beam 1 in this embodiment is used to fix the device on the top of the lifting pole 5 . Such as figure 2 As shown, in this embodiment, the cross-sectional shape of the fixed beam 1 is circular. It can be understood that those skilled in the art can also use fixed beams 1 with other shapes and cross-sections, as long as the device can be firmly installed on the crane. The top of the grill bar 5 gets ...
Embodiment 2
[0047] The difference between this embodiment and embodiment 1 is only that the specific structure of the connection assembly 2 used therein is partly different from that of embodiment 1, and the rest of the structure is the same as that of embodiment 1. Therefore, for the sake of brevity, the differences from Embodiment 1 are mainly described here.
[0048] Such as Figure 4 As shown, the main difference between this embodiment and Embodiment 1 is that the connection assembly 2 further includes a conversion sleeve 24, and the conversion sleeve 24 is sleeved between the sliding sleeve 21 and the bearing 22; the inner surface of the conversion sleeve 24 and the sliding sleeve 21 The outer surface is interference fit, and the outer surface of the conversion sleeve 24 and the inner surface of the bearing 22 are interference fit. The provided conversion sleeve 24 can fixedly connect the sliding sleeve 21 and the conversion sleeve 24 whose shapes and sizes do not match each other,...
Embodiment 3
[0052] The difference between this embodiment and embodiment 2 is only that the method used to prevent the sliding sleeve 21 from rotating around the fixed beam 1 is different, and the rest of the structure is the same as that of embodiment 2. Therefore, for the sake of brevity, the differences from Embodiment 2 are mainly described here.
[0053] Such as Figure 5 As shown, the main difference between this embodiment and Embodiment 2 is that the cross-sectional shape of the fixed beam 1 is set as a rounded rectangle to prevent the sliding sleeve 21 from rotating around the fixed beam 1 . It can be understood that those skilled in the art can also set the cross-sectional shape of the fixed beam 1 as a square, as long as the sliding sleeve 21 socketed therein can be prevented from rotating around the fixed beam 1 . Compared with the method of preventing the sliding sleeve 21 from rotating around the fixed beam 1 through the engagement of the limiting protrusion 10 and the groo...
