According to the utility model, the steam turbine cylinder installation alignment pull steel wire device is simple in structure and convenient in use; the steel wire can be adjusted within a small range in vertical and horizontal directions to reach an imaginary axial center of the steam turbine; and then stationary components of the steam turbine like a cylinder and a separation plate are located accurately, so the labor intensity of the maintenance personnel is reduced and the work efficiency is improved.
Description
Technical field
The utility model relates to a kind of steam turbine installation centering and draws steel wire device.
Background technology
Existing steam turbine is looked for the more use dummy shaft of middle mode Alignment Method, in alignment process, uses dummy shaft, but has relatively high expectations because of circumferential machining accuracy and the surface smoothness of dummy shaft, and processing is difficulty comparatively; For coordinating the use of dummy shaft, the false bearings of a special processing must be respectively installed at two ends simultaneously; While adjusting dummy shaft position, relatively waste time and energy.Therefore, need one at the overhaul of steam turbine initial stage, locate rapidly and accurately the concrete installation site of the steam turbine such as cylinder and dividing plate stationary parts, reduce the device of the workload of rotor alignment and gap regudation of steam sealing.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of simple in structure, easy to use, can make steel wire on four direction, adjust among a small circle up and down, make steel wire reach the imaginary axial centre point of steam turbine, again by the steam turbine such as cylinder and dividing plate stationary parts precise positioning, thereby reduce maintainer's labour intensity, the steam turbine of increasing work efficiency is installed centering and is drawn steel wire device.
For addressing the above problem, the utility model adopts following technical scheme:
A kind of steam turbine is installed centering and is drawn steel wire device, comprise support, gripper shoe, vertical rod, adjustment nut, draw steel wire rack, riser, adjusting lever, steel wire and hearing prosthesis, described gripper shoe is positioned at support top and is flexibly connected with support, described vertical rod and adjustment nut are positioned at gripper shoe top, the described steel wire rack that draws is positioned at vertical rod and adjustment nut top, described riser is provided with two, is separately fixed at and draws steel wire rack top, described adjusting lever runs through two risers, and described steel wire one end is looped around on adjusting lever, the other end is connected with hearing prosthesis.
As preferably, described gripper shoe and draw steel wire rack to be all flat cuboid setting.
As preferably, described adjusting lever is cylindrical setting.
As preferably, described steel wire is separately furnished with a micrometer.
The beneficial effects of the utility model are: owing to being provided with support, whole device can be fixed on the workbench of steam turbine one end, adjust nut and adjusting lever owing to being provided with, can be by tightening or unscrewing adjusting lever and adjust nut and adjust steel wire in the position vertically and in horizontal direction, steel wire is adjusted to axial centre point position, owing to being provided with steel wire and hearing prosthesis, can judge with micrometer and hearing prosthesis the distance of cylinder or dividing plate and steel wire, by the adjustment of distance, realize the concrete location of cylinder and dividing plate, thereby complete fast the adjustment of the steam turbine such as cylinder or dividing plate stationary parts, reduce the workload of turbine rotor alignment and gap regudation of steam sealing.
Brief description of the drawings
Fig. 1 is the plane that a kind of steam turbine installation of the utility model centering draws steel wire device.
Detailed description of the invention
Consult shown in Fig. 1, a kind of steam turbine is installed centering and is drawn steel wire device, comprise support 1, gripper shoe 2, vertical rod 3, adjust nut 4, draw steel wire rack 5, riser 6, adjusting lever 7, steel wire 8 and hearing prosthesis 9, described gripper shoe 2 is positioned at support 1 top, and be flexibly connected with support 1, described vertical rod 3 and adjustment nut 4 are positioned at gripper shoe 2 tops, the described steel wire rack 5 that draws is positioned at vertical rod 6 and adjustment nut 7 tops, described riser 6 is provided with two, be separately fixed at and draw steel wire rack 5 tops, described adjusting lever 7 runs through two risers 3, described steel wire 8 is looped around on adjusting lever 7, the other end is connected with hearing prosthesis 9.
Described gripper shoe 2 and draw steel wire rack 5 to be all flat cuboid setting, flat cuboid is made more for convenience, and also situation is arbitrarily changed shape more.
Described adjusting lever 7 is cylindrical setting, is convenient to coordinate steel wire 8 to rotate.
Described steel wire 8 is separately furnished with a micrometer (not shown), for the measurement of relevant parameter, also can use other survey tools of the same type.
When work, be fixed on the workbench of steam turbine one end by support 1, steel wire 8 is fixed on and draws on steel wire rack 5, places a same device at the steam turbine other end, and steel wire 8 runs through the axial location of whole cylinder, and with predetermined tight power.First, by tightening or unscrewing adjusting lever 7 and adjust nut 4 and adjust steel wire 8 in the position vertically and in horizontal direction, steel wire 8 is adjusted to axial centre point position, again by judge the distance of cylinder or dividing plate and steel wire 8 with micrometer and hearing prosthesis 9, by the adjustment of distance, realize the concrete location of cylinder and dividing plate, thereby complete fast the adjustment of the steam turbine such as cylinder or dividing plate stationary parts, reduce the workload of turbine rotor alignment and gap regudation of steam sealing.
The beneficial effects of the utility model are: owing to being provided with support, whole device can be fixed on the workbench of steam turbine one end, adjust nut and adjusting lever owing to being provided with, can be by tightening or unscrewing adjusting lever and adjust nut and adjust steel wire in the position vertically and in horizontal direction, steel wire is adjusted to axial centre point position, owing to being provided with steel wire and hearing prosthesis, can judge with micrometer and hearing prosthesis the distance of cylinder or dividing plate and steel wire, by the adjustment of distance, realize the concrete location of cylinder and dividing plate, thereby complete fast the adjustment of the steam turbine such as cylinder or dividing plate stationary parts, reduce the workload of turbine rotor alignment and gap regudation of steam sealing.
The above, be only detailed description of the invention of the present utility model, but protection domain of the present utility model is not limited to this, and any variation of expecting without creative work or replacement all should be encompassed in the new protection domain of this practicality and be as the criterion.
