Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The excavator rotary platform provided by the embodiment of the invention is used for installing an upper installation component of the platform, and comprises: a plurality of platform units; each platform unit is used for mounting at least part of the platform upper mounting assembly; the platform units are detachably connected.

When the excavator rotary platform provided by the embodiment of the invention is used, when workers need to hoist the excavator, the platform units are disconnected, so that the platform units are separated. At the moment, at least part of the platform upper part mounting assemblies are mounted on each platform unit, namely the platform upper part mounting assemblies are divided into a plurality of parts by the platform units, and finally the excavator is enabled to form sub-assemblies with the same number as the platform units. In the lifting process, after the working personnel respectively lift and convey the plurality of sub-assemblies to the preset positions, the plurality of platform units are connected together again.

According to the excavator rotary platform, the weight of single lifting can be reduced, the excavator rotary platform is simple to assemble and short in time, the field rescue speed can be increased under the rescue and emergency rescue environment, and the efficiency is improved.

As shown in fig. 1, fig. 2 and fig. 4, on the basis of the above embodiment, further, the plurality of platform units includes a first platform 1 and a second platform 2; the platform upper part mounting assembly comprises an engine split charging 3, a silencer 4, a top cover 5 and a covering piece 6; the second platform 2 is used for installing an engine sub-assembly 3, a silencer 4, a top cover 5 and a covering piece 6; a bracket 7 is arranged on the first platform 1; the second platform 2 is arranged on the bracket 7; the first platform 1 is detachably connected with the second platform 2.

Wherein, the bracket 7 and the first platform 1 can be welded or detachably connected.

The first platform 1 and the second platform 2 can be detachably connected in various ways, for example: bolted, riveted or snap-fit connections, etc.

In this embodiment, during installation, the worker places the second platform 2 on the bracket 7 and then connects the second platform 2 with the first platform 1. Because engine partial shipment 3, muffler 4, roof cover 5 and covering 6 all set up on second platform 2, the weight that second platform 2 need bear is great, and the effect that can play the support to second platform 2 is played in the setting of bracket 7, reduces the moment of flexure that the junction between first platform 1 and the second platform 2 bore.

As shown in fig. 1 and fig. 2, on the basis of the above embodiment, further, the bracket 7 is provided with a first limiting member 8, and the second platform 2 is provided with a second limiting member 9; the first limiting part 8 is sleeved outside the second limiting part 9.

The first limiting member 8 and the second limiting member 9 may be sleeves. The inner diameter of the first limiting member 8 is larger than the outer diameter of the second limiting member 9. In the using process, when the worker installs the second platform 2, the worker inserts the second limiting member 9 into the first limiting member 8. The first limiting part 8 limits the second limiting part 9.

In addition, the first stopper 8 and the second stopper 9 may be rectangular frames. The rectangular frame can also play a limiting role and can limit the relative rotation between the first limiting part 8 and the second limiting part 9.

Specifically, the first limiting member 8 and the bracket 7 may be welded, and the second limiting member 9 and the second platform 2 may be welded.

In this embodiment, in the installation process, the worker places the second platform 2 on the bracket 7, and makes the first limiting member 8 sleeve the outside of the second limiting member 9.
