Description

Technical Field

[0001] The utility model relates to the technical field of fan disassembly and assembly tools, and particularly relates to a fan disassembly and assembly tool for an excitation regulator power cabinet. Background Art

[0002] There is a thyristor rectifier bridge in the power cabinet of the generator excitation system. In the power cabinet of the excitation system, a fan system is installed below the thyristor rectifier bridge to enhance ventilation and reduce the heat inside the cabinet. During the operation of the rectifier cabinet, in accordance with the operation mode of two main units and two standby units, the air flow inside the rectifier cabinet is increased to cool the thyristor rectifier bridge. When the cooling fan reaches the operating hours or a sudden situation occurs, the cooling fan needs to be replaced.

[0003] Patent No.: CN 218082531 U provides a fan disassembly and assembly tool for an excitation regulator power cabinet, which solves the problem of uneven force during the disassembly and assembly of the fan fixing screws in the prior art, and has the effects of improving the stability of the use of the disassembly and assembly tool and enhancing the ability of the disassembly and assembly tool to disassemble and install the fan screws.

[0004] However, during the use of this solution, when operating the ratchet wrench above the mounting plate to turn the bolt, when people usually turn the bolt with a wrench, in order to ensure that the wrench is stably clamped with the bolt, they often habitually apply a certain downward pressure to the wrench. Therefore, when the staff operates the ratchet wrench, they habitually press down on the ratchet wrench, and then press down on the mounting plate to a certain extent, causing the mounting plate to warp to a certain extent. Since there is a certain gap between the sleeve and the bolt, at this time, the sleeve and the bolt are no longer perpendicular to each other, and a certain skew will occur, resulting in the disassembly of the bolt not being smooth, reducing the use effect of the device. Therefore, a fan disassembly and assembly tool for an excitation regulator power cabinet is proposed. Content of the Utility Model

The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0025] See also Figures 1-4The utility model provides a technical solution: a fan disassembly and assembly tool for an excitation regulator power cabinet, comprising an L-shaped mounting plate 1, the surface of the mounting plate 1 is fixedly connected with an L-shaped abutment frame 2, the inner wall of the mounting plate 1 is rotatably connected with a first gear 9, the surface of the first gear 9 is provided with a sleeve 8 for screwing the bolts on the fan, the inner wall of the mounting plate 1 is slidably connected with a moving plate 3, the surface of the moving plate 3 is rotatably connected with a first pulley 11, the inner wall of the mounting plate 1 is also rotatably connected with a first pulley 11, the surfaces of the two first pulleys 11 are transmission-connected with a belt 12, the surface of the first pulley 11 on the inner wall of the mounting plate 1 is coaxially fixedly connected with a second gear 10, the surface of the second gear 10 is meshed with the surface of the first gear 9, the diameter of the second gear 10 is smaller than the diameter of the first gear 9, thereby increasing the output torque of the first gear 9, improving the tightening degree of the fan screw and facilitating the unscrewing of the fan screw.

[0026] The first pulley 11 on the movable plate 3 is coaxially fixedly connected with a torsion block 15, and a countersunk hole is provided on the torsion block 15, into which the input end of the ratchet wrench can be inserted. When the device is in use, the abutment frame 2 is attached to the surface of the fan, and the sleeve 8 covers the bolt to be twisted, and then the input end of the ratchet wrench is inserted into the torsion block 15, and then the ratchet wrench is rotated, and then the second gear 10 is driven to rotate through the transmission of the belt 12, thereby driving the first gear 9 and the sleeve 8 to rotate, and then the bolt is twisted, and the bolt is removed by twisting it at the bottom of the mounting plate 1. When force is applied to the ratchet wrench, the abutment frame 2 and the surface of the fan are in conflict with each other, and then when the driving force is applied to the mounting plate 1, it is blocked by the abutment frame 2, and the mounting plate 1 will not be skewed, so that the sleeve 8 is always in a state of being vertically sleeved on the bolt, so that the disassembly of the fan is smoother and smoother, thereby improving the use effect of the device, which is worthy of promotion.

[0027] Furthermore, the threaded rotation of the contact frame 2 is connected to the second screw rod 7, and the inner sliding connection of the contact frame 2 is connected to the lifting plate 16. The second screw rod 7 penetrates the surface of the lifting plate 16 and is connected to the internal thread of the lifting plate 16. Both sides of the contact frame 2 are slidably connected to the adjustment plate 18. The bottom of the lifting plate 16 is fixedly connected to two extrusion blocks 17 with a right-angled triangle cross-section. The inclined surface of the extrusion block 17 is slidably connected to the surface of the adjustment plate 18, and then the staff can drive the lifting plate 16 to rise and fall in the contact frame 2 by rotating the second screw rod 7, thereby driving the extrusion block 17 in the contact frame 2. The device is lifted and lowered so that the extrusion block 17 pushes or pulls the adjustment plate 18, thereby adjusting the length of the adjustment plate 18 protruding from the surface of the contact frame 2, so that the overall thickness of the contact frame 2 can be adjusted, so that the vertical surface of the contact frame 2 can be adjusted according to the position of the bolt on the fan. The thickness of the vertical surface of the contact frame 2 is adjusted to ensure that the vertical surface of the contact frame 2 can always be in contact with the fan, counteracting the driving force at the bottom of the mounting plate 1, and ensuring that the sleeve 8 is always in a state of being vertically sleeved on the bolt, thereby improving the scope of application of the device, improving the practicability of the device, and worthy of promotion.

The surface of the slide plate 4 is fixedly connected to a spring 14, and the end of the spring 14 away from the slide plate 4 is fixedly connected to the inner wall of the mounting plate 1, so as to drive the slide plate 4 to reset.

[0030] When it is necessary to remove the higher bolts, the staff can rotate the first screw 5 to drive the movable plate 3 to gradually move away from the mounting plate 1, so that the first pulley 11 on the movable plate 3 stretches the belt 12, and the belt 12 squeezes the second pulley 13, thereby pushing the slide plate 4 to slide in the mounting plate 1 and compressing the spring 14, so that the overall length of the device can be changed, which makes it convenient for the staff to remove the higher bolts, further improves the scope of application of the device, has a higher use effect, and improves the convenience of using the device.

[0031] Working principle: When in use, the abutment frame 2 is attached to the surface of the fan, and the sleeve 8 covers the bolt to be tightened, and then the input end of the ratchet wrench is inserted into the torsion block 15, and then the ratchet wrench is rotated, and then the second gear 10 is driven to rotate through the transmission of the belt 12, thereby driving the first gear 9 and the sleeve 8 to rotate, and then the bolt is tightened.
