Description

Technical Field

[0001] This utility model relates to the field of wind power installation technology, specifically a portable oil pump motor replacement tool. Background Technology

[0002] A wind turbine is a device that converts wind energy into electrical energy. It mainly consists of wind turbine blades, a hub, a gearbox, a generator, a tower, a yaw system, and a control system. Wind drives the blades to rotate, which in turn drives the generator to produce electricity, which is ultimately fed into the power grid. It is an important representative of clean energy.

[0003] In the prior art, the authorized announcement number CN215037053U discloses a tooling for replacing the oil pump motor of a wind turbine gearbox, including a support beam, a pulley block slidably connected on the support beam, a lifting device hanging on the pulley block, a support rod fixedly connected to the end of the support beam, and one end of the support rod being fixedly connected to a buckle through a connecting rod.

[0004] As wind turbines age, the failure rate of gearbox cooling systems is increasing year by year, with damage to oil pump motors and mechanical pumps becoming more severe, leading to frequent turbine shutdowns. Due to the unique installation location of the oil pump motor and the relatively limited space inside the nacelle, replacing the oil pump motor and mechanical pump is not only time-consuming and labor-intensive but also significantly reduces efficiency, causing considerable inconvenience to the normal operation and maintenance of wind turbines. Therefore, a portable oil pump motor replacement fixture is proposed. Utility Model Content

[0013] Preferably, the nozzle is movably mounted above the drum via a lead screw and slider.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1.

[0016] 2. In this application, the drive shaft can drive the horizontal transmission shaft and the vertical transmission shaft to rotate synchronously. When the horizontal transmission shaft rotates, it drives the screw jack to operate, causing the piston plate to move upward, thereby forcing the grease in the oil tank into the delivery pipe, and spraying it onto the wire rope on the drum through the nozzle at the end of the delivery pipe, thus lubricating the wire rope. When the vertical transmission shaft rotates, it drives the nozzle to move back and forth, thereby evenly distributing the grease on the surface of the wire rope and improving the lubrication effect.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: As Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a portable oil pump motor replacement fixture, including a support arm 1, a boom 3 rotatably mounted on the upper end of the support arm 1, a support arm 2 rotatably mounted between the boom 3 and the support arm 1, a winding mechanism 6 fixedly mounted on the support arm 1, a lubrication mechanism 7 mounted on the positioning frame 601, a steel wire rope 5 wound on the drum 602, and a hook 4 fixedly mounted at the end of the steel wire rope 5.

[0024] Specifically, hook 4 can hook onto the motor, and then the wire rope 5 can be wound up by the winding mechanism 6 to lift the motor, facilitating motor replacement. The support arm 1, in conjunction with the boom 3, can adjust the motor's position. The lubrication mechanism 7 can be used in conjunction with the winding mechanism 6 to facilitate lubrication of the wire rope 5.

[0025] Example 2: Figure 2 and Figure 3As shown, the winding mechanism 6 includes a positioning frame 601 fixedly mounted on the support arm 1. A drum 602 is rotatably mounted inside the positioning frame 601. A large gear 603 is fixedly mounted at one end of the drum 602. A small gear 606 is rotatably mounted below the large gear 603 and meshes with the large gear 603. A protective cover 604 is fixedly mounted on one side of the positioning frame 601. A drive shaft 605 is rotatably mounted on the positioning frame 601. A crank 607 is fixedly mounted at one end of the drive shaft 605, and the small gear 606 is fixedly mounted on the drive shaft 605. A wire rope 5 is wound on the drum 602, and a hook 4 is fixedly mounted at the end of the wire rope 5.

[0026] Specifically, when the operator forcefully turns the crank handle 607, this action is directly transmitted to the connected drive shaft 605, causing the pinion gear 606 on the drive shaft 605 to rotate. The rotation of the pinion gear 606 is not isolated; through gear meshing, it drives the mating large gear 603 to rotate as well. The rotation of the large gear 603 is further transmitted to the drum 602, causing it to rotate as well. This series of mechanical transmission processes ultimately achieves the orderly winding and unwinding function of the wire rope 5. In this way, the operator can easily lift the motor, greatly facilitating motor replacement and making the entire replacement process more efficient and smooth.

[0027] Example 3: Figure 2 and Figure 4 As shown, the lubrication mechanism 7 includes an oil drum 711 fixedly installed on one side of the positioning frame 601 and a clutch 713 fixedly installed on the side wall of the positioning frame 601. A lead screw frame 701 is fixedly installed on the upper end of the positioning frame 601. A reciprocating lead screw 702 is rotatably installed on the lead screw frame 701. A lead screw slider 703 is installed on the reciprocating lead screw 702. A nozzle 704 is fixedly installed on the lead screw slider 703. A vertical drive shaft 706 is installed at one end of the reciprocating lead screw 702. A nozzle 704 is rotatably installed at the lower end of the vertical drive shaft 706. A horizontal drive shaft 707 and a screw jack 709 are fixedly installed at the bottom of the oil tank 711. A piston plate 710 is fixedly installed at the output end of the screw jack 709. A linkage shaft 708 is fixedly installed at the input end of the screw jack 709. A delivery pipe 712 connects the oil tank 711 and the nozzle 704. Helical gears 705 are fixedly installed on the output shafts of the reciprocating screw 702, the vertical drive shaft 706, the horizontal drive shaft 707, the linkage shaft 708, and the clutch 713, and the helical gears 705 mesh together.

[0028] Specifically, the drive shaft 605 can drive the horizontal drive shaft 707 and the vertical drive shaft 706 to rotate synchronously. When the horizontal drive shaft 707 rotates, it drives the linkage shaft 708 to rotate, which in turn drives the screw jack 709 to operate, causing the piston plate 710 to move upward, pressing the grease in the oil tank 711 into the delivery pipe 712, and releasing it to the wire rope 5 on the drum 602 through the nozzle 704 at the end of the delivery pipe 712, thus lubricating the wire rope 5. When the vertical drive shaft 706 rotates, it drives the reciprocating screw 702 to rotate. When the reciprocating screw 702 rotates, it drives the nozzle 704 on the screw slider 703 to move back and forth, thereby evenly releasing the grease onto the surface of the wire rope 5 and improving the lubrication effect.

[0029] Working principle: The user can turn the crank handle 607, which will drive the small gear 606 on the drive shaft 605 to rotate. After the small gear 606 rotates, it will drive the large gear 603 to rotate. After the large gear 603 rotates, it will drive the drum 602 to rotate, thereby realizing the winding and unwinding of the wire rope 5, which makes it convenient to lift the motor. Simultaneously, the clutch 713 can be controlled to be in the engaged state. When the clutch 713 is in the engaged state, the rotating drive shaft 605 can drive the horizontal drive shaft 707 and the vertical drive shaft 706 to rotate synchronously. When the horizontal drive shaft 707 rotates, it will drive the linkage shaft 708 to rotate, which in turn drives the screw jack 709 to run, causing the piston plate 710 to move upward, thereby pressing the grease in the oil tank 711 into the delivery pipe 712, and releasing it to the wire rope 5 on the drum 602 through the nozzle 704 at the end of the delivery pipe 712, thus achieving lubrication of the wire rope 5. When the vertical drive shaft 706 rotates, it will drive the reciprocating screw 702 to rotate. When the reciprocating screw 702 rotates, it will drive the nozzle 704 on the screw slider 703 to move back and forth, thereby evenly releasing the grease onto the surface of the wire rope 5 and improving the lubrication effect.
