Description

Technical Field

[0001] This utility model relates to the field of flange assembly technology, and in particular to an auxiliary device for assembling a synchronous condenser flange. Background Technology

[0002] In the stable operation of power systems, synchronous condensers, as key equipment for regulating reactive power and maintaining voltage stability, directly affect the reliability of the power network through their assembly quality. The synchronous condenser flange, as the core interface connecting various components, requires high-precision alignment and tightening during assembly to ensure the equipment's sealing and mechanical strength during operation. Synchronous condenser flange assembly auxiliary devices are specifically designed to solve the challenges of synchronous condenser flange assembly. Through functions such as precise positioning, stable clamping, and deviation compensation, they help construction personnel efficiently complete flange assembly operations. Widely used in synchronous condenser installation and maintenance scenarios in power plants, substations, and other similar locations, these devices are important technical equipment for improving the quality and efficiency of synchronous condenser assembly and are of great significance for promoting the intelligent and refined development of power equipment installation.

[0003] Currently, in the assembly of synchronous condenser flanges, existing auxiliary methods are mostly based on simple mechanical frame designs. These mechanical structures typically include a basic support frame, using welded or cast steel to form a load-bearing base, providing a basic support plane for flange assembly. In the positioning stage, locating pins and blocks are manually operated; after manual measurement and marking, these positioning elements are placed between the flange and the connecting components to initially define the flange position. For clamping, manual screw clamps and simple pneumatic clamps are used, applying clamping force to the flange through screw drives or pneumatic pressure to prevent flange displacement during assembly. For deviation adjustment, manual prying and tapping of the flange, or the use of simple tools such as jacks, are mainly relied upon to manually adjust the flange's position and angle in the horizontal and vertical directions. From a technical principle perspective, the rigid support frame provides a stable foundation for flange assembly; the mechanical interference of locating pins and blocks defines the initial position of the flange; the force transmission of the clamps achieves initial flange fixation; and manual external force compensates for flange assembly deviations. The aim is to complete the assembly task of the synchronous condenser flange using a manual-led, simple mechanical-assisted model.

[0004] Existing methods for assembling synchronous condenser flanges, relying on manual operation and simple mechanical structures, have significant deficiencies in controlling flange positioning accuracy. During actual assembly, when manually placing positioning pins and blocks, operational experience leads to uneven force distribution in the simple clamping devices during subsequent clamping and adjustment stages. This can cause slight deformation or displacement of the flange under clamping force, further amplifying positioning deviations and affecting the assembly quality and operational reliability of the synchronous condenser. This has become a core issue hindering the efficient and precise assembly of synchronous condensers. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides an auxiliary device for assembling a camera condenser flange. It aims to improve the existing auxiliary methods in the assembly of camera condenser flanges, which are mostly based on simple mechanical frame designs. Existing devices mainly rely on manual prying and tapping of the flange, or the use of simple tools such as jacks, to manually adjust the position and angle of the flange in the horizontal and vertical directions.

[0007] The expansion assembly includes a cylinder, a rectangular plate fixedly connected to the outer wall of the cylinder, a guide module, a guide slider, an L-shaped support, a rotating shaft, an elongated module, a rotating shaft, a rotating frame, a square seat, and an L-shaped module.

[0008] Furthermore, the lifting assembly includes a second cylinder, a telescopic base column fixedly connected to the outer wall of the second cylinder, a second telescopic column slidably connected to the inner wall of the telescopic base column, a sloped slider fixedly connected to the outer wall of the second telescopic column, a second guide module slidably connected to the outer wall of the sloped slider, a telescopic seat fixedly connected to the outer wall of the second guide module, a first telescopic column slidably connected to the inner wall of the telescopic seat, a lifting platform fixedly connected to the top of the first telescopic column, a pivot support frame fixedly connected to the bottom of the lifting platform, a third pivot rotatably connected to the inner wall of the pivot support frame, and rollers pivotally connected to the outer wall of the third pivot.

[0009] Furthermore, a support column is slidably connected to the inner wall of the base, a guide rail type moving platform is fixedly connected to the top of the support column, and a sliding seat is slidably connected to the top of the guide rail type moving platform.

[0010] Furthermore, the sliding seat is slidably connected to the top of the guide rail type mobile platform, and the guide rail type mobile platform has a sliding groove inside.

[0011] Furthermore, the second cylinder is fixedly connected inside the base, and the second guide module has a sliding groove inside.

[0012] Furthermore, a square seat is fixedly connected to the outer wall of the sliding seat, and the square seat is disposed inside the hollowed-out cylinder.

[0014] Furthermore, an L-shaped module is provided above the base, and four L-shaped modules are provided.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the starting cylinder pushes the rectangular plate to move, the rectangular plate moves the guide module, the guide slider moves the L-shaped support seat, and the L-shaped support seat moves the L-shaped module to expand outward. This solves the problem of relying on manual operation to apply clamping force to the flange, the adjustment process, and the uneven force distribution of the simple clamping device, which easily causes the flange to undergo slight deformation or displacement under the action of clamping force, further amplifying the positioning deviation. It achieves automatic outward expansion to clamp the flange and prevent the flange from shifting during assembly.

[0017] 2. In this utility model, the starting cylinder two pushes the telescopic column two to extend and retract within the telescopic base column. The movement of the telescopic column two drives the inclined slider to move. The guide module two guides the inclined slider. The movement of the inclined slider drives the roller to rotate. The movement of the roller drives the lifting platform to move. The movement of the lifting platform drives the telescopic column one to extend and retract within the telescopic seat. This solves the problem that when manually adjusting deviations, it is impossible to quantitatively compensate for the position and angle deviations of the flange. It achieves automatic leveling, ensuring that the flanges are level during assembly and meeting the accuracy requirements. Attached Figure Description
