In the figure, 1, hanging ring, 2, screw rod, 3, handle, 4, upper cylinder, 5, upper connecting rod, 6, middle cylinder, 7, middle connecting rod, 8, support bar, 9, hard rubber pad, 10, lower connecting rod, 11 and lower cylinder.
Description of the embodiments
The utility model is further described below in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the implementation of the utility model easy to understand.
As can be seen from fig. 1, the utility model relates to a large inner diameter stator shell-entering hoisting tool, which comprises a hoisting ring 1, a screw rod 2, a handle 3, a locking mechanism and a supporting bar 8, wherein the screw rod is a hoisting stress key component, the supporting bar is 3 or more than 3, the locking mechanism comprises an upper cylinder 4, a lower cylinder 11, an upper connecting rod 5 and a lower connecting rod 10, the upper end of the upper connecting rod is hinged with the upper cylinder, the lower end of the upper connecting rod is hinged with the upper part of the supporting bar, the upper end of the lower connecting rod is hinged with the lower part of the supporting bar, the lower end of the lower connecting rod is hinged with the lower cylinder, the screw rod, the supporting bar, the upper connecting rod and the lower connecting rod form an isosceles trapezoid, wherein the upper cylinder is provided with internal threads and is in threaded connection with the screw rod, and the lower cylinder is fixed on the screw rod.
The support bar is also hinged with a middle connecting rod 7, the other end of the middle connecting rod is hinged with a middle cylinder 6, the middle cylinder is fixed on the screw rod, and the middle connecting rod is parallel to the lower connecting rod.
The surface of the supporting bar is provided with a hard rubber pad 9 which is fixed by a screw, so that the friction force during clamping is increased, and the inner surface of the stator is not damaged during tooling expansion.
The working principle of the utility model is as follows:
The locking mechanism is rotated through the handle, the locking mechanism moves downwards and supports the support bar through the connecting rod structure, and the stator is clamped outwards; when the stator is hoisted to a destination, the locking mechanism is reversely rotated through the handle, the locking mechanism moves upwards, the supporting bars are folded through the connecting rod structure, the stator is loosened, and hoisting is completed.
The foregoing has shown and described the basic principles and main features of the present utility model and the advantages of the present utility model. It will be understood by those skilled in the art that the present utility model is not limited to the foregoing embodiments, and that the foregoing embodiments and description are merely illustrative of the principles of this utility model, and various changes and modifications may be made without departing from the spirit and scope of the utility model, and these changes and modifications fall within the scope of the utility model as hereinafter claimed. The scope of the utility model is defined by the appended claims and equivalents thereof.
