The beneficial effects of the utility model are: Large Rotor is lifted, the work such as transhipment time, by using Large Rotor mounting described in the utility model, first can be hung rotor and be placed on this mounting, be turned motor by mounting Son plays certain spacing fixing and supporting role；Can play and allocate and transport whole motor by allocating and transporting this mounting simultaneously and turn afterwards The purpose of son.Therefore, this utility model can be very easy to the upkeep operation of workmen, alleviates operation intensity, shortens Repair time, improve upkeep operation efficiency and construction safety.

Accompanying drawing explanation

Fig. 1 is three dimensional structure schematic diagram of the present utility model；

Figure is labeled as: chassis 1, rotor laying rack 2, inverted trapezoidal groove 21, rotating shaft laying rack 3, arc-shaped slot 31, end gear Frame 4, bearing 5, lifting position 6, turn to part 61.

Detailed description of the invention

With detailed description of the invention, this utility model is further illustrated below in conjunction with the accompanying drawings.

As shown in fig. 1, Large Rotor mounting described in the utility model, including chassis 1, chassis 1 is arranged Having at least two rotor laying rack 2, each rotor laying rack 2 to have recessed inverted trapezoidal groove 21, multiple rotor laying racks 2 are mutual Parallel interval is arranged, and the inverted trapezoidal groove 21 on multiple rotor laying rack 2 is collectively forming one and can be used for placing rotor The placement region at middle part；It is respectively arranged with a rotating shaft on chassis 1 outside the two ends of multiple rotor laying rack 2 entirety to put Frame 3, each rotating shaft laying rack 3 has recessed arc-shaped slot 31, and this arc-shaped slot 31 can corresponding with the rotating shaft of rotor be joined Close；It is respectively arranged with an end divider 4 on chassis 1 outside two rotating shaft laying racks 3, and two end dividers 4 can End one_to_one corresponding with rotor two ends.

Wherein, in use, after rotor is hung onto on mounting, by the ladder that falls on multiple rotor laying racks 2 Shape groove 21 plays the support to rotor central region and position-limiting action；It is said that in general, the size of inverted trapezoidal groove 21, shape etc. can roots Different setting is taked according to the difference needing the rotor size allocated and transported.Certainly, above-mentioned inverted trapezoidal groove 21 also preferably uses and turns The arc-shaped slot that son more mates replaces.It addition, for the quantity of rotor laying rack 2, can arrange multiple in theory, such as Fig. 1 Shown in, the present invention is provided with two rotor laying racks 2.

Meanwhile, this utility model also chassis 1 outside the two ends of multiple rotor laying rack 2 entirety is respectively arranged with one Individual rotating shaft laying rack 3, specifically can refer to shown in accompanying drawing 1；The reason of rotating shaft laying rack 3 is set, mainly in view of typically existing The middle part of rotor has rotor sections, is then shaft at the two ends of rotor；Further, the portion's of turning often its external diameter is relatively big, and The external diameter of rotating shaft is the least；Therefore, in the above-mentioned premise of limited support that the portion of turning carried out already provided with rotor laying rack 2 Under, then the rotating shaft at two ends, portion of turning played support and limit effect by the rotating shaft laying rack 3 arranged by increase, so can improve Support and limit effect to whole rotor.Furthermore, it is contemplated that be the most often also possible in the rotating shaft at two ends, portion of turning sheathed There is bearing part；Therefore, it is possible to the arc-shaped slot 31 on rotating shaft laying rack 3 is arranged to the size matched with corresponding bearing.

It addition, the effect arranging end divider 4 is mainly used for the end of rotor is played position-limiting action, it is to avoid During turning, transporting, rotor is in axial direction collected together.

It addition, for the ease of chassis supports is risen, and then it is easy to through lifting rope to allocate and transport below chassis, this practicality is new Type is additionally provided with multiple bearing 5 protruding from bottom surface, chassis 1 further in the bottom on chassis 1.The effect propping up bearing 5 is to support Play whole chassis and the rotor of top placement；It is said that in general, bearing may be configured as multiple independent support column piece or Person is as illustrated in the drawing by the section bar of horizontally set.More specifically, a bearing 5 may be configured as four, such as four shown in figure Individual bearing 5 is respectively separated and is distributed in bottom, chassis 1 uniformly.

Occur firmly to contact with corresponding groove with the rotor in arc-shaped slot 31 in order to avoid being placed into above-mentioned inverted trapezoidal groove 21, One layer of rubber peel bed course can be set on the internal face of above-mentioned inverted trapezoidal groove 21 and arc-shaped slot 31, to play a protective role.When So, the effect of rubber peel bed course is to play buffer protection function, and other similar materials can be used in theory to replace.

It addition, general, the mounting entirety in this utility model can be spliced by modes such as welding by metal material Form；The materials such as various channel-section steel, steel pipe, steel plate specifically can be used to be spliced.Such as, chassis 1 can be spliced by channel-section steel, and And the most rectangular frame structure after sliceable.

Additionally, it is contemplated that after using channel-section steel etc. to have the steel splicing of corner angle, when adjusting bottom mounting with lifting rope During fortune, easily cause the abrasion of lifting rope in the place of lifting rope corner；To this end, this utility model is further in both sides, chassis 1 and lean on Being respectively arranged with lifting position 6 on the position at nearly two ends, chassis 1, described lifting position 6 includes the cylinder protruding from side edge, chassis 1 Turn to part 61, and this cylinder turns to the axis of part 61 in being horizontally disposed with.So, lifting rope can turn to part accordingly by stumbling Realize corner on 61, and then use cylinder owing to turning to part 61, therefore can effectively reduce the abrasion to lifting rope.
