Description
Technical Field
The utility model belongs to the technical field of machining, and particularly relates to a planet carrier hoisting system.
Background
The planetary support workpiece (shown in figure 1) of the wind turbine generator is formed by coaxially connecting two cylindrical parts with different outer diameters, wherein the cylindrical part with the small outer diameter is called as a long shaft, the cylindrical part with the large outer diameter is called as a support main body of the planetary support main body, and the side wall of the planetary support main body is hollowed out; the end face of the bracket body facing away from the long axis is called a body end face, and the end face of the bracket body facing toward the long axis is called a connection end face. After the casting of the workpiece is finished, the planetary carrier product can be obtained by further processing on a machine tool. Because the workpiece is large in size and heavy in weight, the workpiece is mostly hoisted to the position of the machine tool by adopting a travelling crane and then fixed on a fixture of the machine tool, namely feeding is completed (as shown in fig. 3), and finally, subsequent processing is carried out.
The planet carrier workpiece of the wind turbine generator is irregular in shape, the lifting structure and the mass center are not easy to align during lifting, and the alignment and the lifting are needed to be completed firstly during lifting from the aspects of safety and operation quality, so that the problems of long feeding time, long driving occupation time and the like are caused.
Disclosure of Invention
In order to solve the problems in the prior art and reduce the time of matching the mass center before hoisting, the inventor designs the following hoisting system and tries out:
referring to fig. 1a and 1b, the center of mass of the workpiece 1 is near the end of the long axis, and generally, two slings or lifting belts (here, the "lifting belts" are simply referred to as "slings", such as the first sling 5 and the second sling 6 in fig. 4, and the slings are selected to be not easy to damage the appearance of the workpiece because they need to be in direct contact with the workpiece) are used to lift the workpiece at the front and back (along the axis direction of the workpiece) of the center of mass. During lifting loading, referring to fig. 2a, 2b and 3, the long shaft 2 of the workpiece is required to extend into the large positioning hole 4 of the clamp, and then one end face of the workpiece facing the clamp is propped against by the lifting block of the clamp, and then the pressing block is installed and locked. The second hanging strip 6 circumferentially sleeved on the long shaft has larger external dimension and can affect the matching of the heightening blocks, so when the long shaft 5 enters the large positioning hole to be close to half of the large positioning hole 4, the second hanging strip 6 is removed, and the long shaft part is lifted up by the third hanging strip 7 to finish the subsequent operation (as shown in figure 5). The third strap passes through the through hole in the long shaft in the axial direction of the long shaft, which increases the difficulty of the work. In the process, the hanging belt is replaced, so that the operation time is prolonged.
Although the lifting system solves the problem of long time for aligning the lifting structure and the mass center, the lifting system is replaced in the feeding process to elongate the operation time. The reason is analyzed, the first hanging strip does not interfere with the relative position between the workpiece and the clamp in the whole process, only the second hanging strip interferes, and if the connecting position of the second hanging strip on the workpiece extends upwards, the connecting operation space between the tool and the clamp is avoided, and the hanging strip does not need to be replaced. Accordingly, the utility model provides a planet carrier hoisting system.
The planet carrier hoisting system comprises a planet carrier workpiece and a hoisting tool; the planetary support workpiece is formed by connecting a long shaft and a support main body; the long shaft and the bracket main body are both cylindrical, and the axes of the long shaft and the bracket main body are all straight lineslThe method comprises the steps of carrying out a first treatment on the surface of the The outer diameter of the long shaft is smaller than that of the bracket main body;

in the state of complete feeding of the planetary support, the through hole serving as a lifting tool connecting mechanism is higher than the top of the machine tool fixture.
Under this structure, lift by crane through two hoisting points along the axial of work piece, supplementary hoist mechanism does not take place the skew with the work piece in the radial direction, simultaneously because the thickness of steel sheet is far less than the size of hoist and mount area/hoist cable, avoided the installation interference between work piece and the anchor clamps. However, this structure also has drawbacks:
because adjacent assembly counter bores of the workpiece are not axisymmetric, after the auxiliary hoisting mechanism is adopted for direct hoisting, the workpiece can be caused to rotate circumferentially, and even if the length difference of two steel plates is adjusted, the trend of the circumferential rotation of the workpiece is not eliminated, so that the clamping operation of a clamp is not facilitated.
Further optimizing to: the auxiliary hoisting mechanism is an auxiliary hoisting plate;
the auxiliary hanging plate is composed of steel plates; the auxiliary hanging plate is trapezoid; the lower bottom edge of the auxiliary hanging plate is provided with an upward concave, and the left side and the right side of the concave are provided with through holes as workpiece connecting holes (workpiece connecting mechanisms); two through holes which are bilaterally symmetrical are formed in the upper part of the auxiliary hanging plate and serve as hanging holes (hanging tool connecting mechanisms); a through hole for the pressing block connecting column of the clamp to pass through is formed in the central position of the auxiliary hanging plate; a through hole for the block to pass through is formed beside the workpiece connecting hole;

When engineering is realized, in two realization structures of the auxiliary hoisting mechanism, the thickness requirements of two steel plates/auxiliary hoisting plates are as follows: and in a loading completion state, the gap between the connecting end face and the clamp is larger than the thickness of the steel plate.
Because the thickness of the steel plate is limited, the bearing capacity of the standard shackle corresponds to the size of the opening of the standard shackle, the opening of the large bearing shackle is large, and the difference between the thickness of the steel plate and the size of the opening of the shackle is too large, so that the unstable condition and the like can be brought.
