Problems solved by technology
[0004] Because the rotating mechanism will shake during the hoisting installation or disassembly process, and the diameters of the various parts that make up the rotating mechanism such as the lower box 104 and the gear 105 are different, so that the rotating mechanism is easy to get stuck on a certain wing when passing through or withdrawing from each mounting hole. On the edge plate, the operator needs to adjust the position of the rotating mechanism from the bottom of the installation platform, and the operation is cumbersome
In addition, since the installation and disassembly of the rotating mechanism all take place at high altitude, the risk of operation is increased

Embodiment Construction
[0032] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0033] combine figure 2 As shown, the installation platform of the rotary mechanism of the portal crane includes an upper flange plate 1 , a middle flange plate 2 and a lower flange plate 3 .
[0034] The upper flange plate 1 , the middle flange plate 2 and the lower flange plate 3 are arranged in parallel up and down, and the three are connected by a web 4 .
[0035] On the upper flange plate 1, the middle flange plate 2 and the lower flange plate 3, a first mounting hole 5, a second mounting hole 6, and a third mounting hole 7 are opened respectively, as shown in FIG. image 3 , Figure 4 and Figure 5 shown.
[0036] A first guide part 8 is provided below the first installation hole 5, and the first guide part 8 is in the shape of an inverted funnel. When the rotating mechanism withdraws from the first installation hole 5, the first gui...

The invention discloses a mounting platform of a gantry crane rotating mechanism. The mounting platform comprises an upper flange plate, a middle flange plate and a lower flange plate, wherein a first mounting hole, a second mounting hole and a third mounting hole are formed in the upper flange plate, the middle flange plate and the lower flange plate respectively; an inverted-funnel-shaped first guide part is arranged under the first mounting hole, and the upper edge of the first guide part is in contact with the edge of the first mounting hole; a funnel-shaped second guide part is arranged above the second mounting hole and the lower edge of the second guide part is in contact with the edge of the second mounting hole; a columnar third guide part is arranged between the second mounting hole and the third mounting hole; the upper edge of the third mounting hole is in contact with the edge of the second mounting hole; and the lower edge of the third guide part is in contact with the edge of the third mounting hole. With the adoption of all the guide parts, the rotating mechanism can smoothly penetrate through or exit from each mounting hole in a hoisting mounting or detaching process, so that the mounting and detaching efficiency of the rotating mechanism is improved.
Description
technical field [0001] The invention belongs to the field of portal cranes and relates to a mounting platform for a rotary mechanism of the portal crane. Background technique [0002] The swivel mechanism is an important part of the portal crane. Due to the long arm span, heavy weight and large moment of inertia of the rotating part of the portal crane, the frequency of failure of the rotating mechanism is obviously higher than that of other working mechanisms. [0003] The installation form of the rotating mechanism of the portal crane is basically the same, that is, it is installed in the box beam or I-shaped beam of the rotating platform. Such as figure 1 As shown, the installation platform of the rotary mechanism includes an upper flange plate 101, a middle flange plate 102 and a lower flange plate 103, and there are installation plates on the upper flange plate 101, the middle flange plate 102 and the lower flange plate 103. holes, through the above-mentioned install...
