Detailed Description

In order to make the technical purpose, technical solutions and advantageous effects of the present invention clearer, the technical solutions of the present invention are further described below with reference to fig. 1 to 5 and specific embodiments.

The embodiment of the trolley of the upper rotating container door machine comprises the following steps:

the upper rotating container door machine trolley comprises a lower frame 1, an upper frame 2 and a lifting mechanism 3 arranged on the upper frame 2, a trolley running mechanism 4 and a rotary track 5 are arranged on the lower frame 1, the trolley can run along the trolley running track through the trolley running mechanism 4, a plurality of rotary wheels 6 rolling on the rotary track 5 are arranged on the lower part of the upper frame 2, a rotary driving mechanism is arranged at the position of at least one rotary wheel 6, the rotary track 5 is fixed in the middle of the lower frame 1, the lower frame 1 is in a polygonal structure, the number of the sides of the polygonal structure is more than or equal to six, an X-shaped cable support 7 is arranged above the hoisting mechanism 3, four end parts of the X-shaped cable support 7 are respectively and vertically fixed with a supporting leg 8, and each landing leg 8 is respectively fixedly connected with the lower frame 1, a sliding seat 9 is connected in the X-shaped cable support 7 in a sliding manner, and the sliding seat 9 is rotatably connected with a cable pulley 11 through a rotating shaft 10.

The cable for hoisting mechanism 3 power supply hangs in X type cable support 7 through cable pulley 11, and when hoisting mechanism 3 rotated along with frame 2, cable pulley 11 can move to the suitable position of X type cable support 7 according to the gyration angle under the drive of slide 9, and owing to the setting of pivot 10, can not cause the cable excessively to twist reverse.
