Description

Technical Field

[0001] This utility model relates to the field of maintenance tooling technology, specifically to a turbine generator set servo assembly / disassembly bracket. Background Technology

[0002] The turbine servo is an important component of a hydroelectric power generation system, mainly used to control the opening of the turbine's guide vanes, thereby regulating the flow rate of water entering the turbine. Because the servo is long and slender, when it is under maintenance, one end needs to be removed from its fixed position. This results in the other end receiving a large torque, which can cause structural damage. Therefore, additional support is required for disassembly and assembly. However, there are currently no suitable disassembly and assembly tools, and workers need to spend a long time finding suitable components for temporary support, resulting in low maintenance efficiency.

[0003] In view of this, a design or technical improvement is proposed to solve the above problems.

[0004] The above content is only used to help understand the technical solution of this utility model and does not represent an admission that the above content is the closest prior art. Utility Model Content

The two sets of clamping plates are clamped to the upper crossbar of the support frame, and an adjusting nut threaded onto the first threaded rod is provided on the side of the two clamping plates that is relatively far apart from each other.

[0008] Furthermore, the bottom of the support frame is provided with rollers.

[0009] Furthermore, the bottom of the support frame is also equipped with two sets of track rods for it to move along, wherein the track rods are provided with a first limiting groove for the rollers to limit their movement.

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] like Figure 1-5 The turbine generator servo mounting bracket shown includes a support frame 1, on which multiple sets of support plates 11 are mounted. Each support plate 11 has a slot 12 for mounting the servo. First threaded rods 13 are located on both sides of the bottom of each support plate 11. Two sets of parallel clamping plates 14 pass through the first threaded rods 13. The two sets of clamping plates 14 are clamped onto the upper crossbar 15 of the support frame 1. Adjusting nuts 16, threaded onto the first threaded rods 13, are located on the opposite sides of the clamping plates 11. This device uses the slots 12 on the support plates 11 to adjust the servo. The clamping mechanism provides support to the bottom of the relay during assembly and disassembly, facilitating maintenance. Simultaneously, by rotating the adjusting nut 16, the clamping force of the clamping plate 14 can be adjusted, allowing the support plate 11 to slide laterally on the support frame 1. This allows for adjustment of the support points of the relay according to actual conditions. Furthermore, by changing the position of the adjusting nut 16 on the first threaded rod 13, the first threaded rod 13 can be raised or lowered relative to the clamping plate 14, thereby driving the support plate 11 to achieve height adjustment, better adapting to different relay installation heights.

[0024] In one embodiment, the bottom of the support frame 1 is provided with rollers 2, which facilitates the movement of the support frame 1 and makes the entire bracket easy to move.

[0025] In one embodiment, the bottom of the support frame 1 is also provided with two sets of track rods 3 for it to move. The track rods 3 are provided with a first limiting groove 31 for the rollers 2 to limit their movement. The track rods 3 can be fixed to the ground at the bottom of the relay, and the support frame 1 can be placed on the track rods 3, which facilitates maintenance and disassembly. At the same time, the first limiting groove 31 limits the movement of the support frame 1, so that it can be better aligned with the upper relay.

[0026] In one embodiment, a horizontal fixing plate 4 is provided on the bottom side of the support frame 1, a suspension plate 41 is provided on the horizontal fixing plate 4, a rubber wheel 42 is provided on the suspension plate 41, and a second limiting groove 43 is provided on the side of the track rod 3 for the rubber wheel 42 to limit its movement. By engaging the rubber wheel 42 with the second limiting groove 43, the support frame 1 is restricted to the track rod 3 as a whole, so as to avoid the instability of its movement on the track rod 3.

[0027] In one embodiment, the horizontal fixed plate 4 has a movable groove 44 for the suspension plate 41 to move. Limiting blocks 45 are provided on both sides of the suspension plate 41. Limiting grooves 46 are provided on both sides of the movable groove 44 for the limiting blocks 45 to slide in a limited manner. The bearing on the suspension plate 41 is provided with a second threaded rod 47 that is threadedly connected to the support vertical rod 17 on the support frame 1. When it is necessary to disassemble or assemble the relay, the support frame 1 can be controlled to move on the track rod 3 to find a suitable support position. Then, the second threaded rod 47 is rotated to drive the suspension plate 41 to move towards the support vertical rod 17, thereby driving the rubber wheel 42 to press against the inner wall of the second limiting groove 43, so that the support frame 1 can be locked and supported by the workers.

[0028] In one embodiment, a rubber strip 5 is provided on the upper edge of the support plate 11 to avoid structural damage caused by rigid collision between the relay and the support plate 11.

[0029] In one embodiment, a crossbeam 6 is provided between the track rods 3 to enhance the integrity and rigidity between the track rods 3 and improve the structural strength.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
