Description

Technical Field

[0001] The utility model relates to the field of circulating water pipeline matching adjustment tools, in particular to a circulating water pipeline matching adjustment tool for a gas turbine power plant. Background Art

[0002] At present, the circulating water pipelines of gas turbine power plants are usually large-diameter pipelines, most of which are buried underground. Due to the heavy weight of large-diameter pipelines, lifting tools are usually used for docking. However, there is a lot of uncertainty in the lifting tools, and they shake a lot during the docking process. It is not easy to fine-tune, and the docking work is relatively cumbersome. As a result, most of the construction time will be wasted when aligning and connecting the pipelines during the docking process, and the construction efficiency is low. Utility Model Content

[0003] The purpose of the utility model is to solve the problems existing in the prior art and provide a circulating water pipe matching adjustment tool for a gas turbine power plant, which can be used to adjust the elevation of the pipe to be matched and the axis of the pipe to be matched, thereby ensuring that the circulating water pipe is quickly matched, meeting welding conditions, saving construction time and improving construction efficiency.

[0004] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:

[0005] A tool for adjusting the connection of circulating water pipes in a gas turbine power plant comprises adjustment frames arranged on the left and right sides of the rear end of a first pipe and a height adjustment device arranged at the bottom of the front end of a second pipe. The adjustment frames are arranged axially along the first pipe and extend toward the rear side of the first pipe. A horizontal pushing device is horizontally arranged on each of the adjustment frames.

[0006] Preferably, the adjustment frame is an L-shaped frame welded to the outer side wall of the rear end of the first pipe.

[0007] Preferably, the height adjustment device is a hydraulic lifting device.

[0008] Preferably, a V-shaped block is provided on the top of the hydraulic lifting device.

[0009] Preferably, the horizontal pushing device is an adjusting screw arranged on the adjusting frame, and the adjusting screw horizontally penetrates the adjusting frame and is threadedly connected to the adjusting frame.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] The utility model adjusts the elevation of the second pipe by arranging a height adjustment device at the joint position of the pipes. Compared with the lifting tool, the height adjustment device is easier to accurately adjust the elevation, saving the time for elevation adjustment. By arranging a horizontal pushing device on the side wall of the hoisted first pipe, the axis of the second pipe is adjusted, making the adjustment more accurate and quick, saving the time for adjusting the installation axis in place. It can ensure the rapid jointing of the circulating water pipes, meet the welding conditions, save construction time and improve construction efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.

[0017] Example: As attached Figure 1-3 As shown, the utility model is a tool for adjusting the connection of circulating water pipes in gas turbine power plants, which can solve the problems of large shaking and difficulty in fine-tuning during the connection process of conventional lifting, and most of the construction time will be wasted when aligning and connecting the pipes during the connection process, resulting in low construction efficiency.

[0018] It includes adjustment frames 2 arranged on the left and right sides of the rear end of the first pipeline 1, and a height adjustment device 4 arranged at the bottom of the front end of the second pipeline 3, wherein the height adjustment device 4 is used to adjust the vertical position of the second pipeline 3, wherein the first pipeline 1 is a hoisted pipeline or a main pipeline, and the second pipeline 3 is a pipeline to be hoisted or a pipeline to be matched.

[0019] The adjustment frame 2 can be directly welded on the outer wall of the first pipe 1, and then cut off after the jointing is completed. The adjustment frame 2 is arranged along the axial direction of the first pipe 1, and the adjustment frame 2 extends to the rear side of the first pipe 1. Each of the adjustment frames 2 is horizontally provided with a horizontal pushing device 5.

[0020] Preferably, in order to facilitate the adjustment of the matching, the adjustment frame 2 is an L-shaped frame welded on the outer side wall of the rear end of the first pipe 1, the vertical part of the L-shaped frame is welded on the outer wall of the first pipe 1, and the horizontal pushing device 5 is arranged on the horizontal part of the L-shaped frame. A certain distance is left between the horizontal part of the L-shaped frame and the outer wall of the second pipe 3, so that the horizontal pushing device 5 can adjust the horizontal position of the second pipe 3 conveniently.

[0021] Preferably, in order to reduce costs, the height adjustment device 4 is a hydraulic lifting device.

[0022] Furthermore, in order to ensure stability during adjustment of the position of the second pipeline, a V-shaped block is provided on the top of the hydraulic lifting device.

[0023] Preferably, in order to reduce costs, the horizontal pushing device 5 is an adjusting screw arranged on the adjusting frame 2, the adjusting screw horizontally penetrates the adjusting frame 2 and is threadedly connected to the adjusting frame 2, a threaded hole adapted to the adjusting screw is provided on the adjusting frame 2, the threaded hole penetrates the adjusting frame 2, and the second pipe 3 can be pushed by turning the adjusting screw.

[0024] The utility model arranges a height adjustment device 4 (hydraulic lifting device) at the counterpart position of the pipeline. When the circulating water pipeline is hoisted, the counterpart position of the second pipeline 3 directly falls to the height adjustment device 4. The height adjustment device 4 is close to the pipeline bottom elevation when placed, and only needs to be fine-tuned to complete the adjustment of the elevation of the second pipeline 3 without up and down shaking, so that the elevation adjustment of the second pipeline 3 is easier to accurately adjust the elevation, saving elevation adjustment time.

[0025] The utility model arranges a horizontal pushing device 5 (adjusting screw) at the middle position of the left and right sides of the outer wall of the rear end of the first pipeline 1 (the hoisted pipeline), and the top plate of the end of the adjusting screw is designed to contact the outer wall of the second pipeline 3. The central axis of the second pipeline 3 is fine-tuned by rotating the adjusting screw, so that the central axis of the second pipeline 3 can be adjusted more accurately and quickly, saving the time for adjusting the installation axis in place.
