Detailed ways

Below in conjunction with accompanying drawing, illustrate the specific embodiment of the present utility model.

In the embodiment shown in Fig. 1, Fig. 2 and Fig. 3, a kind of anti-swing rotating crane comprises column 1, and the top of column 1 is provided with first rotating arm device 100, the other of described first rotating arm device 100 One end is provided with a second rotating arm device 101 , below the second rotating arm device 101 , the other end of the second rotating arm device 101 is rotatably connected to the I-beam 2 , and the electric hoist 3 is hoisted below the I-beam 2 , the electric hoist 3 includes its body and a hook 3.1 driven by the body, an anti-sway device 103 is provided between the hook 3.1 and the I-beam 2, and the anti-sway device 103 includes a 4 compression modules 5 between the steel 2, the compression module 5 includes the spring stem 6 fixed on the I-beam 2 and the electric hoist 3, the two spring stems 6 are fixed through the telescopic rod 7 and The compression spring 8 can be compressed, and the compression spring 8 is sheathed outside the circumference of the telescopic rod 7 .

The compression spring 8 is a helical spring that bears the pressure. There will be a certain gap between the coils of the compression spring 8. When it is subjected to an external load, the spring shrinks and deforms to store deformation energy. Through the four compression springs 8 and the telescopic rod 7 , it can constrain the force when changing the vertical center of gravity in four degrees of freedom, and the setting of the compression spring 8 can reduce the rigid impact and prolong the service life of the steel wire or iron chain in the electric hoist 3 .

In the embodiment shown in FIG. 1 , the bottom of the column 1 is fixed to the main body by anchor bolts 9 , and can be fixed on the concrete foundation or along with equipment and other places through the anchor bolts 9 , which is convenient for transportation, assembly and disassembly.

In the embodiment shown in Figure 1, the first rotating arm device 100 includes a pair of first installation frames 10 fixed on the top of the column 1, and the first cycloidal pinwheel reducer is arranged in the two first installation frames 10 11. The driving ends of the two first cycloidal pinwheel reducers 11 are connected to the first rotating shaft 12 by transmission, and the first supporting arm 14 is horizontally fixed on the top shaft of the first rotating shaft 12 . The worker controller transmits a driving command to control the rotation of the first cycloidal pinwheel reducer 11 , and then drives the first rotating arm device 100 to rotate left and right.

Further, the bearing plate 15 is used to support and fix the first support arm 14 and the rotating shaft, so that the axial direction of the first support arm 14 can bear a larger load and ensure stable and reliable rotation.

In the embodiment shown in Figure 1, the second rotating arm device 101 includes a mounting plate 16 fixed at one end of the first support arm 14, and a second mounting frame 17 is fixed on the upper and lower surfaces of the mounting plate 16. The second cycloidal pinwheel reducer 18 is arranged in the installation frame 17, and the driving end of the two second cycloidal pinwheel reducers 18 is connected to the second rotating shaft 19 by transmission. 2 Rotational connection, the worker controller transmits a drive command to control the rotation of the second cycloidal pinwheel reducer 18, and then drives the second rotating arm device 101 to rotate left and right.

It should be noted that the pick-up device of the present utility model is swiveled on 2 places of the I-beam, and the swivel arm can be rotated. It is a lifting equipment for small and medium loads. It has the advantages of simple structure, safety, reliability, high efficiency, energy saving and time saving. It has the characteristics of labor saving and flexibility, and can be operated freely in three-dimensional space. It shows its superiority compared with other conventional lifting equipment in the occasion of segment distance and intensive transportation.

The working principle of the utility model: the operator drives the electric hoist to work through the controller, and the electric hoist uses the hook 3.1 to carry the goods, and then drives the first cycloidal pinwheel reducer 11 and the second cycloidal pinwheel reducer through the controller 18 and the operation of the electric hoist, so that it can work in three-dimensional space. When the cargo is lifted or moved left and right, the center of gravity of the cargo itself is in the vertical direction. Because of the large dynamic inertia, there will be a large swing problem. Through the compression module 5 The four directions above the hook 3.1 are constrained to tend to the vertical direction, and the traction force is respectively applied in the four directions through the telescopic rod 7 and the compression spring 8. At this time, the moving speed of the cargo is relatively slow, and the swing center of the cargo can be tended The vertical direction, and then gradually calm down and reduce the swing range, so that the utility model works stably and reliably, and avoids the potential safety hazard caused by the shaking of the goods.
