Description
Technical Field
The utility model relates to a hoist is stood up to annular part belongs to part assembly auxiliary assembly technical field.
Background
At present, the assembly of wind power main shaft assemblies in China is in a vertical assembly mode, each assembly part is vertically assembled after the main shaft is erected according to an assembly structure, and the main shaft is integrally turned over after the main shaft is integrally assembled. But has the following disadvantages: 1. the integral turning-over of the main shaft after assembly has higher requirements on-site traveling. 2. Workers are required to ascend during the assembly process (the conventional wind power main shaft is about 3 meters). 3. The main bearing is damaged by turning over of the wind power main shaft assembly.
In order to solve the problems, the main shaft is horizontally arranged and assembled, and when the main shaft is horizontally arranged, the annular part needs to be quickly lifted and turned over. Therefore, a ring-shaped part turning hanger is needed.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that an annular part stands up hoist is provided to above-mentioned prior art, simple structure, the simple operation can carry out quick handling and stand up to annular part.
The utility model provides a technical scheme that above-mentioned problem adopted does: a lifting appliance for turning over an annular part comprises a hoop, wherein the annular part is fixed in the hoop, a connecting frame is arranged on the hoop, and two ends of the connecting frame are respectively hinged with the hoop, so that the hoop can rotate around a hinged point to drive the annular part to synchronously rotate; and the connecting frame is provided with a hanging ring.
The hoop is characterized in that positioning plates are symmetrically arranged on the outer side of the hoop and are respectively fixed at two ends of the connecting frame, a plurality of positioning holes which are circumferentially and uniformly arranged at intervals are respectively formed in the positioning plates and the hoop, and after the annular part rotates to the position, the indexing bolts penetrate through the corresponding positioning holes to realize the fixed connection of the positioning plates and the hoop.
The number of the positioning holes is 4, so that the annular part can be switched among a horizontal front-side placing state, a horizontal back-side placing state and a vertical placing state.
Compared with the prior art, the utility model has the advantages of: the utility model provides a cyclic annular part stands up hoist, cyclic annular part is fixed in the staple bolt, and the staple bolt can be rotatory round the revolving axle for the staple bolt can switch between horizontal state and vertical state, drives cyclic annular part and can openly place the state at the level, the state is placed to the horizontal reverse side and switches between the vertical state of placing. This application simple structure, the simple operation, and can carry out quick handling and stand up cyclic annular part.
Drawings
Fig. 1 is a schematic view of a turning-over hanger for annular parts according to an embodiment of the present invention;
in the figure, a lifting ring 1, a connecting frame 2, a hoop 3, a rotating shaft 4, a positioning hole 5, an indexing bolt 6 and a positioning plate 7 are shown.
Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in fig. 1, the turning-over lifting appliance for the annular part in the embodiment includes an anchor ear 3, the anchor ear 3 is internally provided with the annular part, and the anchor ear is locked by a bolt, so that the annular part is fixed in the anchor ear 3. The hoop 3 is provided with a connecting frame 2, the connecting frame 2 is of an inverted Y shape, two branch ends of the connecting frame 2 are respectively provided with a positioning plate 7, and the positioning plates 7 are symmetrically arranged on the outer side of the hoop 3. The connecting frame 2 and the positioning plate 7 are connected with the hoop 3 through the rotating shaft 4, so that the hoop 3 can rotate around the rotating shaft 4 to drive the annular part to synchronously rotate, namely the annular part can rotate 360 degrees in the connecting frame 2. The connecting frame 2 is provided with a hanging ring 1, so that the lifting is convenient.
Set up 4 locating holes 5 that the even interval of hoop was arranged on above-mentioned locating plate 7 and the staple bolt 3 respectively for staple bolt 3 can switch between horizontality and vertical state, drives cyclic annular part and can openly place the state, the horizontal reverse side is placed the state and is vertically placed and switch between the state, realizes standing up of cyclic annular part. After the annular part rotates to the position, the indexing bolt 6 penetrates through the corresponding positioning hole 5, so that the positioning plate 7 is fixedly connected with the hoop 3, and the placement state of the annular part is further kept.
When the main shaft is assembled in a side-lying mode, the hoop is horizontally placed and then is embraced to the annular part and is locked through the bolt, and therefore the hoop is enabled to embrace the annular part tightly. The lifting device is hooked on the lifting ring, the connecting frame and the hoop are lifted afterwards, and the hoop rotates around the rotating shaft, so that the hoop is in a vertical state, the annular parts are driven to be in a vertically placed state, and when the lifted annular parts are adjusted to be in a needed posture, the annular parts are inserted into the corresponding positioning holes through the indexing bolts, and the annular parts are turned over.
The lifting device is simple in structure and convenient to operate, and can quickly lift and turn over the annular part.
In addition to the above embodiments, the present invention also includes other embodiments, and all technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
