Description

Technical Field

[0001] This utility model relates to the field of maintenance device technology, specifically a positioning clamp for the maintenance of hydropower equipment. Background Technology

[0002] Clamps used for maintaining hydroelectric power equipment are tools specifically designed to fix, support, or position equipment components during inspection, installation, or maintenance. Their role is crucial. When maintaining heavy components such as turbines, generator rotors, and guide vanes, clamps can firmly fix the components to prevent slippage or falling due to gravity or external forces, thus ensuring personnel safety. When installing turbine blades or bearings, clamps can accurately hold the components in position to ensure that assembly tolerances meet requirements.

[0003] According to a patent published on the China Patent Network, the patent title is "A Positioning Fixture for Maintenance of Hydropower Equipment," patent application number 201721532539.7. This utility model relates to the field of maintenance equipment technology and discloses a positioning fixture for maintenance of hydropower equipment. It includes a base, with a first motor fixedly connected inside the base. A lead screw is fixedly connected to the output end of the first motor. A first bearing is provided on the surface of the lead screw, and a threaded block is threaded onto the surface of the lead screw. A sleeve is fitted onto the surface of the threaded block, and a hydraulic cylinder is fixedly connected to the surface of the sleeve. A hydraulic rod is fixedly connected to one end of the hydraulic cylinder. This positioning fixture for maintenance of hydropower equipment, by setting up a first motor, lead screw, hydraulic cylinder, and rotating device, allows access to workpieces that are difficult to manually repair. The first motor and lead screw extend the workpiece to a certain length, expanding the working range. The rotating device then rotates the fixture, making it easier to repair and inspect workpieces with difficult angles, thus achieving the purpose of ease of use. However, the aforementioned positioning clamps cannot guarantee that there is sufficient support on both sides when the user places the device. Due to the large size of the device, the clamping device in the middle may be subjected to excessive force, causing the object to shift.

[0004] Therefore, the positioning fixture needs to be redesigned and modified to effectively prevent it from shifting or tilting. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a positioning clamp for the maintenance of hydropower equipment, which has the advantage of preventing the clamped device from tilting and solves the problem that the large size of the device leads to unstable clamping and positional displacement.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning clamp for the maintenance of hydropower equipment, comprising a frame;

A transmission sleeve 34 is threadedly connected to the surface of the threaded rod 33. The top of the transmission sleeve 34 extends through to the top of the support frame 31. A support plate 35 is fixedly connected to the top of the transmission sleeve 34. A limit slide rod 36 is fixedly connected to the bottom of the support plate 35. The bottom of the limit slide rod 36 extends through to the inner cavity of the support frame 31. A fan mechanism 4 is fixedly connected to the outside of the support frame 31.

[0032] refer to Figure 3 The fan mechanism 4 includes a transmission frame 41, which is fixedly connected to the outside of the support frame 31. A slide rod assembly 42 is slidably connected to the inner cavity of the transmission frame 41. A spring assembly 43 is fixedly connected to the bottom of the slide rod assembly 42. The bottom of the spring assembly 43 is fixedly connected to the inner wall of the transmission frame 41. A positioning groove 44 is provided on the outside of the slide rod assembly 42. A horizontal plate 45 is fixedly connected to the top of the slide rod assembly 42. A fan assembly 46 is fixedly connected to the top of the horizontal plate 45. A positioning pin 47 is provided through the outside of the transmission frame 41.

[0033] As a technical optimization of this utility model, the fan mechanism 4 enables the drying of the clamped device components, drying the water stains on their surface, preventing water stains from dripping and affecting subsequent processing operations, thus providing convenience for users.

[0034] refer to Figure 3 A reinforcing plate 5 is fixedly connected to the inner side of the transmission frame 41, and the inner side of the reinforcing plate 5 is fixedly connected to the outer side of the support frame 31.

[0035] As a technical optimization of this utility model, the reinforcing plate 5 can reinforce the transmission frame 41, strengthen the connection between the transmission frame 41 and the support frame 31, and enable the two to be connected more stably.

[0036] refer to Figure 2 Limiting blocks 6 are fixedly connected to both sides of the motor 32, and the bottom of the limiting blocks 6 is fixedly connected to the inner wall of the support frame 31.

[0037] As a technical optimization of this utility model, the setting of the limiting block 6 can limit the motor 32, prevent the motor 32 from shifting position, and ensure that the motor 32 can run in the specified position.

[0038] refer to Figure 2 Both sides of the support frame 31 are fixedly connected with right angle plates 7, and the inner side of the right angle plates 7 is fixedly connected to the outer side of the frame 1.

[0039] As a technical optimization of this utility model, the right-angle plate 7 can strengthen the connection of the support frame 31, ensuring a more stable connection between the support frame 31 and the frame 1.

[0040] refer to Figure 2 A reinforcing sleeve 8 is fixedly connected to the surface of the limiting slide bar 36, and the top of the reinforcing sleeve 8 is fixedly connected to the bottom of the support plate 35.

[0041] As a technical optimization of this utility model, the reinforcement sleeve 8 can reinforce the limiting slide bar 36, ensuring a more stable connection between the limiting slide bar 36 and the support plate 35, and preventing the limiting slide bar 36 from falling off.

[0042] The working principle and usage process of this utility model are as follows: First, after the motor 32 starts, the threaded rod 33 rotates, driving the transmission sleeve 34 to move axially along the threaded rod 33. The top of the transmission sleeve 34 is connected to the support plate 35, and the bottom is connected to the support frame 31 through the limit slide rod 36, ensuring that the support plate 35 can only be raised and lowered vertically to avoid rotational deviation. By controlling the forward and reverse rotation of the motor 32, the support plate 35 is raised and lowered, thereby adjusting the height of the clamp assembly 2 to adapt to the parts to be maintained of different sizes. When it is necessary to adjust the fan position, press down on the horizontal plate 45 to overcome the elasticity of the spring assembly 43, so that the slide rod assembly 42 slides down along the inner cavity of the transmission frame 41, driving the fan assembly 46 close to the surface of the part. Insert the positioning pin 47 into the positioning groove 44 on the outside of the slide rod assembly 42 to fix the height of the fan assembly 46 and ensure the drying distance is stable. After the fan assembly 46 starts, it blows away the water stains on the surface of the clamped part to accelerate drying and prevent water stains from dripping and affecting the subsequent processing accuracy.

[0043] In summary, this positioning clamp for hydropower equipment maintenance, by setting up a support mechanism, changes the traditional positioning clamp for hydropower equipment maintenance. This addresses the issue where, during clamping operations, the clamping device is too large to be fully clamped, potentially leading to positional displacement of the disassembled device. The clamp provides auxiliary support, preventing such displacement.
