An equipment support pedestal that mounts aperture adapters

Abstract

This utility model discloses a device support base with adaptable mounting hole diameter, belonging to the technical field of support bases. It includes a base body with a mating hole on its upper surface. An aperture adaptation mechanism is installed inside the mating hole, comprising an adjusting sleeve, an adjusting stud, and a hollow frustum. The adjusting sleeve is fixed to the inner wall of the base body, the adjusting stud is threaded through the adjusting sleeve, and the hollow frustum is fixed to the upper surface of the adjusting stud. Through this aperture adaptation mechanism, when the hollow frustum rises and abuts against the wall of the device mounting lug, hollow frustums of different aperture sizes can replace the mating hole with the device mounting lug, thus avoiding the risk of poor compatibility between the mating hole and the device mounting lug, which could lead to insufficient clamping force after bolt insertion and cause positional displacement on the base body during equipment vibration.

Description

Technical Field

[0001] This utility model relates to the field of support base technology, specifically to a device support base with an adapted mounting hole diameter. Background Technology

[0002] In the wind power industry, the stable installation of key equipment such as wind turbine gearboxes and generators is crucial to the safe operation of wind turbine generator sets. As a key component connecting the equipment and the foundation structure, the equipment support base directly affects the stability and reliability of the equipment installation. In existing technologies, traditional equipment support bases typically employ a fixed-diameter mating hole design. When there is a deviation between the size of the equipment mounting lugs and the mating holes on the base, the bolts cannot form an effective clamping force after insertion. During the operation of the wind turbine generator, the equipment continuously vibrates, and this poor compatibility can easily cause the equipment to shift position on the base. This not only affects the normal operating efficiency of the equipment but may also lead to serious consequences such as loosening of connecting parts and equipment damage. At the same time, due to the mismatch in hole diameter, it is difficult to align the axes of the equipment mounting lugs and the mating holes on the base during installation, increasing the difficulty of bolt installation and making it difficult to guarantee installation accuracy. Therefore, a device support base with an adaptable mounting hole diameter is needed to solve the problems existing in the prior art. Utility Model Content

[0003] The purpose of this invention is to provide a device support base with an adapted mounting hole diameter to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a device support base with adaptable mounting hole diameter, comprising a base body, wherein a mating hole is provided on the upper end face of the base body, and a hole diameter adaptation mechanism is provided inside the mating hole. The hole diameter adaptation mechanism includes a height adjustment sleeve, a height adjustment stud, and a hollow frustum. The height adjustment sleeve is fixed to the inner wall of the base body, the height adjustment stud is threaded through the interior of the height adjustment sleeve, and the hollow frustum is fixed to the upper end face of the height adjustment stud. Through the hole diameter adaptation mechanism, when the hollow frustum rises and abuts against the wall of the device mounting lug, hollow frustums with different hole diameters can replace the mating hole and mate with the device mounting lug, thereby avoiding the risk of poor compatibility between the mating hole and the device mounting lug, which would result in the bolt not forming an effective clamping force after insertion, causing the device to shift position on the base body when vibrating.

[0005] Preferably, the inner wall of the height adjustment sleeve is provided with a height adjustment thread groove, and the height adjustment stud is threadedly connected to the height adjustment sleeve.

[0006] Preferably, the upper end face of the hollow truncated cone is provided with a bolt through hole, and the lower end of the height adjustment stud is fixed with an anti-slip hand knob.

[0007] Preferably, an insert is provided at the center of the upper end face of the height adjustment stud, and a locking nut is embedded and fixed in the insert of the height adjustment stud.

[0008] Preferably, the locking nut is positioned directly below the bolt hole, and the screw hole of the locking nut and the bolt hole are arranged along the same axial direction.

[0009] Preferably, the four hollow frustums are respectively arranged in the four docking holes of the base body.

[0010] This utility model provides a device support base with an adapted mounting hole diameter, which has the following advantages compared with the prior art: With the set aperture adaptation mechanism, after the hollow truncated cone rises and presses against the wall of the equipment mounting lug, the hollow truncated cone with different aperture sizes can replace the docking hole and dock with the equipment mounting lug. This avoids the problem that poor compatibility between the docking hole and the equipment mounting lug will result in the bolt not forming an effective clamping force after it is inserted, which may cause the position to shift on the base body when the equipment vibrates.

[0011] By using a hollow truncated cone, as the cone extends into the mounting lug, the conical wall of the hollow truncated cone contacts the wall of the mounting lug, ensuring that the axis of the mating hole is aligned with that of the mounting lug, thus providing a uniform and gapless channel for bolt insertion.

[0014] 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.

[0015] Please see Figure 1-4 This utility model provides a device support base with an adaptable mounting hole diameter, including a base body 1. A mating hole 2 is formed on the upper surface of the base body 1. An aperture adaptation mechanism 3 is disposed inside the mating hole 2. The aperture adaptation mechanism 3 includes an adjusting screw sleeve 4, an adjusting stud 5, and a hollow frustum 6. The adjusting screw sleeve 4 is fixed to the inner wall of the base body 1. The adjusting stud 5 is threaded through the interior of the adjusting screw sleeve 4. The hollow frustum 6 is fixed to the upper surface of the adjusting stud 5. An adjusting threaded groove 11 is formed on the inner wall of the adjusting screw sleeve 4. The adjusting stud 5 is threadedly connected to the adjusting screw sleeve 4. A threaded groove 11 is formed on the upper surface of the hollow frustum 6. The lower end of the height adjustment stud 5 is fixed with an anti-slip knob 7. Before the equipment is connected to the base body 1, the height adjustment stud 5 is rotated clockwise so that it is screwed into the height adjustment groove 11 on the inner wall of the height adjustment sleeve 4. As the height adjustment stud 5 rises, the hollow frustum 6 fixed on its upper end face gradually extends out of the docking hole 2 and is inserted into the generator equipment mounting ear hole. Taking advantage of the gradually changing diameter of the hollow frustum 6, it is continuously rotated until its conical wall tightly abuts against the wall of the equipment mounting ear hole, thus completing the adaptation to different hole diameters and avoiding the problem of insufficient bolt clamping force due to poor hole diameter adaptation, eliminating the hidden danger of equipment vibration and displacement.

[0016] It is worth noting that an insertion port 9 is provided at the center of the upper end face of the height adjustment stud 5. A locking nut 10 is embedded and fixed in the insertion port 9 of the height adjustment stud 5. The locking nut 10 is located directly below the bolt through hole 8. The screw hole of the locking nut 10 and the bolt through hole 8 are arranged in the same axial direction. After the hole diameter of the hollow frustum 6 is matched, the axis of the equipment mounting ear hole and the docking hole 2 are ensured to be precisely aligned by the action of the conical wall of the hollow frustum 6. Then, bolts are used to pass through the equipment mounting ear hole and the bolt through hole 8 on the hollow frustum 6 in sequence, and finally locked with the locking nut 10 in the insertion port 9 of the height adjustment stud 5, so as to realize the firm fixation of the equipment and the base body 1, and at the same time form a gapless bolt through channel to ensure the stability and reliability of the equipment installation.

[0017] It is worth noting that the four hollow truncated cones 6 are respectively set in the four docking holes 2 of the base body 1.

[0018] This solution has the following working process: The base body 1 is used to support key equipment in the wind turbine, such as wind turbine gearboxes and generators, to provide stable support and prevent vibration displacement. During the process of placing the generator equipment on the base body 1, the mounting ears of the generator equipment are connected to the various docking holes 2 of the base body 1 in the hoisting state. Then, the height adjustment stud 5 is turned from the anti-slip knob 7, which drives the height adjustment stud 5 to screw along the thread of the height adjustment sleeve 4, so that the hollow truncated cone 6 extends out of the docking hole 2 and enters the mounting ear hole of the generator equipment. Since the diameter of the hollow truncated cone 6 gradually changes from small to large, after the hollow truncated cone 6 rises and presses against the wall of the mounting ear hole, the hollow truncated cone 6 with different hole diameters can replace the docking hole 2 and dock with the mounting ear hole, thereby avoiding the risk of position displacement on the base body 1 when the equipment vibrates due to poor compatibility between the docking hole 2 and the mounting ear hole. After the equipment mounting lug is positioned on the hollow frustum 6, bolts are sequentially passed through the equipment mounting lug and bolt through-hole 8 and then threaded onto the locking nut 10 to achieve a firm lock between the equipment and the base body 1. During the process of the frustum extending into the mounting lug, the conical wall of the hollow frustum 6 will contact the wall of the equipment mounting lug, ensuring that the axis of the mating hole 2 is aligned with the axis of the mounting lug, providing a uniform and gapless channel for bolt insertion.
