Description

Technical Field

[0001] The utility model belongs to the field of propeller maintenance, and specifically relates to a fixture for propeller maintenance. Background Art

[0002] A propeller is a propeller installed on a ship or an airplane. It is composed of blades that are driven by power. During the propeller processing process, it needs to be inspected and repaired. During the inspection and repair process, the propeller needs to be clamped and fixed.

[0003] The Chinese patent number CN202022447960.6 discloses a bracket with a novel stable structure. The bracket with the novel stable structure includes a base; two connecting rods, both of which are symmetrically fixedly installed at the bottom of the base, and the two connecting rods are distributed in a rectangular array; two first support columns, both of which are provided with a cavity and a first groove, and both of which are provided with a first through hole at the top of the two cavities, and the two connecting rods respectively pass through the two first through holes; and a cross plate, which is fixedly installed on the two first support columns.

[0004] When the utility model is in use, the ability to clamp and fix the propeller is poor, and the position of the propeller cannot be adjusted during maintenance, resulting in frequent movement of workers during the maintenance process, which is very inconvenient.

[0005] In view of this, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0030] The utility model will now be described in further detail with reference to the accompanying drawings.

[0031] See also Figure 1-5 As shown, in this embodiment, a clamp for repairing a propeller is provided, comprising a body 1; a base 2 is installed at the bottom end of the body 1, a level 21 is installed at one side of the base 2, a supporting mechanism 8 is installed around the bottom end of the base 2, a turntable 6 is installed at the upper end of the body 1, a large bearing 7 is installed on the outer side of the turntable 6, the large bearing 7 is installed at the internal position of the body 1, a power mechanism 19 is installed at the bottom end of the turntable 6, the power mechanism 19 is installed at the internal position of the body 1, and a clamping mechanism 20 is installed at the upper side of the turntable 6.

[0032] One aspect of the application of this embodiment is: when in use, the body 1 is placed at a specified position through the base 2, and the base 2, i.e., the body 1, is leveled through the support mechanism 8. After leveling, the propeller is placed on the upper side of the turntable 6, and the propeller is clamped and fixed by the clamping mechanism 20 on the upper side of the turntable 6. After the fixation is completed, the propeller can be inspected and repaired. During the inspection and repair process, when the propeller needs to be moved, the power mechanism 19 is turned on by the switch, and the power mechanism 19 will drive the turntable 6 to rotate along the large bearing 7, so as to adjust the position of the propeller. There is no need for the staff to frequently adjust the position, which is convenient for the inspection and repair of the propeller.

[0033] In this embodiment, the supporting mechanism 8 is composed of a threaded rod 10 and a threaded barrel 11. The bottom end of the threaded rod 10 is rotatably installed inside the threaded barrel 11, and the threaded barrel 11 is installed on the upper side of the base 2. When the supporting mechanism 8 is in use, the threaded rod 10 is rotated. During the rotation process, the threaded rod 10 is moved up and down by the action of the threaded barrel 11 to level the base 2.

[0034] In this embodiment, a handle 9 is installed at the upper end of the threaded rod 10, and a base plate 12 is rotatably installed at the lower end of the threaded rod 10. A friction pad 13 is attached to the lower end of the base plate 12 by adhesive. The handle 9 is provided for easy holding, thereby facilitating the rotation of the threaded rod 10. The base plate 12 is provided for increasing the contact area between the lower end of the threaded rod 10 and the ground, and the friction pad 13 is provided for increasing the friction between the lower end of the base plate 12 and the ground.

[0035] In this embodiment, a fixing bolt 14 is provided on the outside of the threaded barrel 11, and the fixing bolt 14 is rotatably installed on the outside of the threaded barrel 11. The setting of the fixing bolt 14 is used to increase the friction between the threaded barrel 11 and the threaded rod 10 to avoid the phenomenon of thread slippage between the threaded rod 10 and the threaded barrel 11 during use.

[0036] In this embodiment, the clamping mechanism 20 consists of a pneumatic clamp 5 and an annular flexible clamp 3. The annular flexible clamp 3 is installed on the upper side of the turntable 6. The pneumatic clamp 5 is installed on the upper side of the turntable 6 and is located in the middle of the annular flexible clamp 3. An air guide slip ring 15 is rotatably installed at the bottom end of the clamping mechanism 20. The bottom end of the air guide slip ring 15 is installed inside the base 2. When the clamping mechanism 20 is in use, the pneumatic clamp 5 is inserted into the mounting hole in the middle of the propeller, and the middle position of the propeller is clamped and fixed by the pneumatic clamp 5. The setting of the annular flexible clamp 3 can clamp and fix the blades of the propeller.

[0037] In the present embodiment, a plurality of flexible clamping rods 4 are slidably installed at the upper end of the annular flexible clamp 3, and a rubber pad 22 is attached to the upper end of the flexible clamping rod 4 by adhesive. When the flexible clamping rod 4 contacts with the propeller, it can shrink according to the shape of the propeller to form a contour groove, which can increase the stability of the propeller fixation. At the same time, the provision of the rubber pad 22 can isolate the flexible clamping rod 4 from contact with the propeller during use, thereby preventing the flexible clamping rod 4 from causing wear on the outer surface of the propeller.

[0038] In this embodiment, the power mechanism 19 is composed of an electric motor 18, a pinion 17 and an internal gear 16. The internal gear 16 is installed at the bottom end of the turntable 6. The internal gear 16 and the pinion 17 are meshed and connected. The pinion 17 is installed on the upper side of the electric motor 18. The electric motor 18 is installed inside the base 2. When the power mechanism 19 is in use, the electric motor 18 is turned on by a switch, and the electric motor 18 will drive the pinion 17 to rotate. During the rotation, the pinion 17 drives the turntable 6 and the propeller on the upper side of the turntable 6 to rotate through the internal gear 16, so as to facilitate the maintenance of the propeller.
