Description

Technical Field

[0001] This utility model belongs to the field of generator set casing hoisting technology, specifically referring to a generator set casing hoisting component. Background Technology

[0002] In the production, transportation and installation of generator sets, the existing published patent CN222007037U proposes a generator set housing hoisting assembly, which hoists the generator set housing by fixing a U-shaped hook to the other end of a steel cable and using a locking rod set on the U-shaped hook to pass through a pull ring and be threadedly connected to the U-shaped hook.

[0003] However, in actual use, it relies on manual operation of the locking rod to connect and disconnect with the pull ring, which is not convenient for automatically hooking and disconnecting the pull ring. The operation process is cumbersome, labor-intensive and inefficient. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a generator set casing hoisting assembly, which effectively solves the problems of inconvenient operation and high manpower consumption.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: a generator set housing hoisting assembly, including a housing, pull rings fixed at the top of the housing near the four corners, a support frame provided above the housing, and a hoisting ring fixed at the top center of the support frame;

[0006] A rotating shaft is symmetrically arranged on both sides of the support frame. Hooks are fixed at both ends of the rotating shaft, and the opening of the hooks faces the pull ring. A gear is fixed in the middle of the rotating shaft. A U-shaped connecting frame is provided on one side of the gear and slides vertically. The inner walls of both sides of the U-shaped connecting frame are provided with racks that mesh with the gear.

[0007] The cylinder has its body fixed to the bottom of the support frame, and its movable end is connected to the bottom of the U-shaped connecting frame, which is used to drive the connecting frame to move up and down.

[0008] Preferably, the support frame is provided with protective covers on both sides, the protective covers cover the gear and the U-shaped connecting frame, and the bottom of the protective covers is open.

[0009] Preferably, the connecting frame is provided with guide grooves on both sides that slide vertically relative to the support frame to restrict its horizontal displacement.

[0010] Preferably, the surface of the pull ring is covered with a rubber anti-slip layer, and the mounting base of the pull ring is integrally formed with the housing.

[0011] Preferably, the swing angle of the hook is between 0 and 90°.

[0012] The beneficial effects of the above structure of this utility model are as follows: by setting a cylinder to drive the connecting frame to move up and down, thereby driving the gear, rotating shaft and hook to rotate, the hook can automatically hook and release the pull ring without manual operation, which greatly improves the efficiency of hoisting operation and reduces manpower input, and is especially suitable for large-scale generator set casing hoisting operation.

[0018] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The utility model will be further described in detail below with reference to the accompanying drawings.

[0020] like Figure 1-4As shown, the present invention proposes a generator set housing hoisting assembly, including a housing 1, with pull rings 2 fixed at the top of the housing 1 near the four corners. The surface of the pull rings 2 is covered with a rubber anti-slip layer, and the mounting base of the pull rings 2 is integrally formed with the housing 1. A support frame 3 is provided above the housing 1, and a hoisting ring 4 is fixed at the top center of the support frame 3.

[0021] like Figure 3 As shown, the rotating shaft 5 is symmetrically rotated on both sides of the support frame 3. Hooks 6 are fixed at both ends of the rotating shaft 5. The opening of the hooks 6 faces the pull ring 2. A gear 7 is fixed in the middle of the rotating shaft 5. A U-shaped connecting frame 8 is located on one side of the gear 7 and slides vertically. Both sides of the inner wall of the U-shaped connecting frame 8 are provided with racks 9 that mesh with the gear 7.

[0022] like Figure 2 As shown, the cylinder body of cylinder 10 is fixed at the bottom of support frame 3, and the movable end is connected to the bottom of U-shaped connecting frame 8. It is used to drive the connecting frame 8 to move up and down. When cylinder 10 retracts, U-shaped connecting frame 8 drives gear 7 to rotate, causing hook 6 to rotate inward and hook pull ring 2. When cylinder 10 extends, hook 6 rotates outward and disengages from pull ring 2.

[0023] like Figure 4 As shown, the support frame 3 is provided with protective covers 11 on both sides. The protective covers 11 cover the gear 7 and the U-shaped connecting frame 8. The bottom of the protective covers 11 is open to facilitate the movement of the connecting frame 8. The connecting frame 8 is provided with guide grooves 12 on both sides that slide vertically relative to the support frame 3 to limit its horizontal displacement.

[0024] In order to successfully hook and detach from the pull ring 2, the swing angle of the hook 6 is between 0 and 90°. When the cylinder 10 drives the connecting frame 8 to move upward, the hook 6 starts to rotate from the initial horizontal position. When it rotates to about 90°, it can just hook the pull ring 2 on the housing 1. When the cylinder 10 retracts and drives the hook 6 to rotate in the opposite direction, it rotates from 90° back to 0°, thus separating from the pull ring 2.

[0025] In actual use, place the generator set housing 1 in a suitable position, move the support frame 3 of this hoisting assembly to directly above the housing 1, connect the lifting ring 4 to the hoisting equipment, and adjust the position of the support frame 3 to ensure that the hook 6 can accurately correspond to the pull ring 2 on the housing 1.

[0026] When the cylinder 10 is activated, it retracts and moves the connecting frame 8 upward. The racks 9 on both sides of the connecting frame 8 mesh with the gears 7, causing the gears 7 to rotate. This, in turn, drives the rotating shaft 5 and the hook 6 to rotate synchronously, causing the hook 6 to rotate inward and hook the pull ring 2, thus completing the automatic hooking process. The lifting equipment then pulls the lifting ring 4, which in turn lifts the entire lifting assembly and the housing 1, allowing for normal lifting, transportation, or installation operations.

[0027] Once the housing 1 is transported or installed in place, the cylinder 10 is activated to extend it, the connecting frame 8 moves downward, causing the gear 7 to rotate in the opposite direction, and the shaft 5 and hook 6 rotate in the opposite direction as well. The hook 6 separates from the pull ring 2, and then the hoisting assembly can be removed for the next hoisting operation.

[0028] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
