Description

Technical Field

[0001] The utility model relates to the technical field of dove - tail rib processing, and particularly to a turning - over auxiliary tool for long dove - tail ribs. Background Technique

[0002] Dove - tail ribs are components of hydro - generators. The dove - tail ribs of large generators are relatively long. During the storage process in the workshop, they are usually stacked on the ground. Sometimes, in order to transfer workpieces, the workpieces need to be turned over. Currently, for a dove - tail rib with a length exceeding 3 meters, usually two people are required to cooperate in turning it over, which is quite laborious and has a high labor intensity. Summary of the Invention

[0003] The purpose of the utility model is to solve the problems existing in the above - mentioned prior art, and provide a turning - over auxiliary tool for long dove - tail ribs.

[0004] The specific scheme of the utility model is: a turning - over auxiliary tool for long dove - tail ribs, including an operating rod. A handle is provided at the upper end of the operating rod, and a fork - shaped structure is provided at the lower end of the operating rod. The fork - shaped structure includes a first L - shaped bracket and a second L - shaped bracket. The first L - shaped bracket and the second L - shaped bracket form a U - shaped fork structure. One side of the first L - shaped bracket is fixedly connected to the operating rod. A waist - shaped hole is provided on the short side of the second L - shaped bracket, and the operating rod is arranged in the waist - shaped hole. A locking screw is installed on the first L - shaped bracket. The locking screw passes through the waist - shaped hole and is connected with a nut to lock the first L - shaped bracket and the second L - shaped bracket.

[0005] Further, a counterbore is provided on the bottom surface of the first L - shaped bracket, and the nut of the locking screw is installed in the counterbore.

[0006] Further, a gasket is installed between the nut and the locking screw, and the size of the gasket is larger than the width of the waist - shaped hole.

[0007] Further, reinforcing rib plates are provided on the outer sides of the first L - shaped bracket and the second L - shaped bracket.

[0008] The utility model has the following beneficial effects: 1. When using this tool for the auxiliary turning - over of long dove - tail ribs, a single person can complete the operation, which is more labor - saving and greatly reduces the labor intensity; 2. By setting the U - shaped fork structure as a sliding connection between the first L - shaped bracket and the second L - shaped bracket, the width can be adjusted to adapt to workpieces of different widths.

[0014] See Figures 2 - 4 , this embodiment is a turning - over auxiliary tool for long dove - tail ribs, including an operating rod 1. The upper end of the operating rod 1 is provided with a handle, and the lower end of the operating rod 1 is provided with a fork - shaped structure. The fork - shaped structure includes a first L - shaped bracket 2 and a second L - shaped bracket 3. The first L - shaped bracket 2 and the second L - shaped bracket 3 form a U - shaped fork structure. One side of the first L - shaped bracket 2 is fixedly connected to the operating rod 1, and the short side of the second L - shaped bracket 3 is provided with a kidney - shaped hole 7. The operating rod 1 is arranged in the kidney - shaped hole 7. A locking screw 6 is installed on the first L - shaped bracket 2. The locking screw 6 passes through the kidney - shaped hole 7 and is connected with a nut 4 to lock the first L - shaped bracket 2 and the second L - shaped bracket 3.

[0015] Further, a counterbore is provided on the bottom surface of the first L - shaped bracket 2, and the nut of the locking screw 6 is installed in the counterbore.

[0016] Further, a gasket 5 is installed between the nut 4 and the locking screw 6, and the size of the gasket 5 is larger than the width of the kidney - shaped hole 7.

[0017] Further, reinforcing rib plates 8 are provided on the outer sides of both the first L - shaped bracket 2 and the second L - shaped bracket 3.

[0018] See Figure 1 , when this utility model is in use, the operator first adjusts the relative positions of the first L - shaped bracket 2 and the second L - shaped bracket 3 according to the width of the workpiece 9. By sliding the second L - shaped bracket 3 to adjust the width between them to match the width of the workpiece 9, and then locking the first L - shaped bracket 2 and the second L - shaped bracket 3 through the locking screw 6 and the nut 4; then the operator holds the handle part, inserts the U - shaped fork downward on both sides of the workpiece 9 at the mid - point of the workpiece 9, and then drives the operating rod 1 and the U - shaped fork to rotate horizontally with force. The U - shaped fork drives the workpiece 9 to achieve turning - over. When it is turned to a certain angle, the U - shaped fork can be withdrawn, and then the workpiece 9 is turned 90° by its own gravity to achieve turning - over. The force - applying part of the operator is at the upper end of the operating rod 1, while the force of the operating rod 1 on the workpiece 9 is at the lower end, so that the lever principle can be used to achieve the purpose of labor saving, and a single person can perform the turning - over operation of the dove - tail rib, reducing the labor intensity.
