[0002] The steam turbine inlet pipe is a core component connecting the boiler and the steam turbine, responsible for safely and efficiently transporting high-temperature, high-pressure steam to the turbine. Its design, materials, and layout directly affect the unit's efficiency, safety, and lifespan. Due to the significant size and weight of the steam turbine inlet pipe, specialized equipment is required for clamping and handling it during processing and installation.

[0003] During handling operations, the handling device mainly relies on its upper protective clamping device to support and limit the main body of the pipeline. Traditional handling devices often use a clamping seat structure, which clamps and supports the pipeline during handling through multiple sets of support clamps. Since a large number of clamps are required for fixing, the operator needs to tighten multiple sets of clamping structures one by one during installation. After transportation is completed, the clamps need to be disassembled and unlocked one by one. The operation is complicated and very inconvenient. Therefore, a pipeline protective clamping device for pipeline handling is proposed. Utility Model Content

[0024] Example

[0025] Please see Figure 1-5This utility model provides a technical solution: a pipe protection clamping device for pipe handling, including a support plate seat 1, a lifting plate seat 2, a lifting cylinder 3, an arc-shaped push block 4, and a fixed clamp seat 5. The support plate seat 1 serves as the installation support structure for the device. To facilitate installation with an external platform structure, as shown in the attached diagram... Figure 1 As shown, mounting brackets 6 are fixedly installed on both sides of the support plate base 1. The upper part of the mounting bracket 6 is provided with bolt mounting holes for bolt installation. The lifting plate base 2 is driven to move and lift on the upper part of the support plate base 1 by the lifting cylinder 3. Specifically, in order to guide and support the lifting plate base 2, lifting guide columns 7 are evenly arranged on the upper part of the support plate base 1. The lifting guide columns 7 are solid metal guide columns. The lower part of the lifting guide columns 7 is fixedly installed with the support plate base 1. The upper part of the lifting plate base 2 is provided with guide insertion holes. The lifting guide columns 7 are movably inserted into the guide insertion holes. This can improve the movement stability of the lifting plate base 2 when it moves up and down. In order to provide rigid impact support and protection for the lower part of the lifting plate base 2, a protective support pad 8 is fixedly fitted on the lower part of the lifting guide column 7.

[0026] The lifting cylinder 3 is a high-thrust electric cylinder, specifically, it can be a servo electric cylinder of the existing technology model LTW-110, as shown in the attached figure. There are two lifting cylinders 3, which are evenly installed at equal intervals on the bottom center of the support plate seat 1. The lifting cylinders 3 are fixed to the lower part of the support plate seat 1 by bolts. The push rod end of the lifting cylinder 3 is fixed to the lower part of the lifting plate seat 2. The lifting plate seat 2 is a liftable type. The lifting plate seat 2 is driven by the lifting cylinders 3. Through the lifting drive and the self-weight pressing clamping working structure, the upward movement and unlocking and downward clamping actions of multiple sets of fixed clamp seats 5 can be synchronously driven. There is no need for manual fastening and disassembly of the fixed clamp seats 5, which can effectively reduce the manpower consumption of the device operation. Moreover, the multiple sets of fixed clamp seats 5 can move synchronously, which can effectively reduce the installation time of the device and greatly improve the efficiency of pipeline handling.

[0027] The fixing clamp 5 is used for clamping and fixing the pipe, as shown in the attached document. Figure 4 As shown, there are four sets of fixed clamps 5, with two fixed clamps 5 in each set. To facilitate the connection and installation of the fixed clamps 5, a clamp mounting groove is provided through the upper part of the lifting plate seat 2. A support column 9 is fixedly installed inside the clamp mounting groove. The fixed clamps 5 are rotated and installed inside the clamp mounting groove by the support column 9. To facilitate the clamping and installation of the pipe, a pipe clamping groove is provided on the upper inner side of the fixed clamp 5. To improve the stability of the pipe clamping, an anti-slip pad 10 is fixedly installed on the inner side of the pipe clamping groove. To further improve the safety of pipe handling, a strap connecting seat 11 for safety strap installation is fixedly installed on the outer side of the fixed clamp 5.

[0028] As attached Figure 5 As shown, in order to achieve the guided clamping drive, a guided inclined surface is provided at the lower part of the fixed clamp 5. The guided inclined surface is located on the lower inner side of the fixed clamp 5, and the arc-shaped push block 4 is installed on the upper part of the support plate 1, as shown in the attached figure. Figure 3 As shown, to facilitate the connection and installation of the arc-top push block 4, push block mounting slots are evenly provided through the middle of the support plate seat 1. The arc-top push block 4 is fixedly installed on the inner side of the push block mounting slot by bolts. The upper part of the arc-top push block 4 is provided with an arc-shaped guide surface. The arc-shaped guide surface and the guide slope are slidably connected. The self-weight pressing clamping working structure is adopted. Multiple sets of fixed clamps 5 are supported and flipped on the upper part of the lifting plate seat 2 by the support shaft column 9. The lower slope guide part of the fixed clamp 5 is in movable contact with the arc-top push block 4. After the pipeline is placed, the fixed clamp 5 can be automatically flipped and clamped by the self-weight pressing of the pipeline and the contact guide of the arc-top push block 4, so as to quickly and firmly clamp and fix the pipeline.

[0029] Working principle or structural principle: The device is installed by mounting the side seat 6 in conjunction with the transport platform. Before pipe installation, the lifting plate seat 2 is driven by two sets of lifting cylinders 3 to be in a lifting support state. During the process, the lower guide slope of the fixed clamp seat 5 gradually separates from the arc-shaped push block 4, so that the fixed clamp seat 5 is in an outward-folding unlocked state. Then, the pipe is slowly supported and placed in the clamping space of the fixed clamp seat 5 by hoisting. Then, the lifting plate seat 2 is slowly moved down by the lifting cylinders 3. During the downward movement, the lower guide slope of the fixed clamp seat 5 contacts the arc-shaped guide surface of the upper part of the arc-shaped push block 4. Through the contact guide, the fixed clamp seats 5 on both sides flip inward. The placed pipe is clamped and fixed. After installation, the fixed clamp 5 can be automatically flipped and clamped by the downward pressure of the pipe's own weight and the contact guide of the arc top push block 4. Due to the downward pressure of its own weight and the pulling limit of the lifting cylinder 3, the pipe can be stably clamped and fixed. When transporting over long distances or on uneven ground, the safety straps need to be connected and installed through the strap connecting seat 11 to ensure transportation safety. Then, the pipe is moved and transported by the platform. After arriving at the location, the lifting cylinder 3 drives the lifting plate seat 2 to move slowly upward, so that the fixed clamp 5 slowly flips outward and enters the unlocked state. Then, the pipe is lifted and moved by the hoisting equipment to complete the moving and transportation work.

[0030] In summary, this protective clamping device adopts a self-weight downward clamping working structure. Multiple sets of fixed clamps 5, arranged in pairs, are supported and rotated on the upper part of the lifting plate seat 2 by the support shaft column 9. The lower inclined guide part of the fixed clamp 5 is in contact with the arc top push block 4. After the pipeline is placed, the fixed clamp 5 can be automatically rotated and clamped by the self-weight downward pressure of the pipeline and the contact guide of the arc top push block 4, which can quickly and securely clamp and fix the pipeline. In addition, the lifting plate seat 2 is raised and lowered by the lifting cylinder 3. The lifting drive, combined with the self-weight downward clamping working structure, can realize the synchronous drive of the upward movement and unlocking of multiple sets of fixed clamps 5 and the downward movement and clamping action. There is no need for manual fastening and disassembly of the fixed clamps 5, which can effectively reduce the manpower consumption of the device operation. Moreover, the multiple sets of fixed clamps 5 can move synchronously, which can effectively reduce the installation time of the device and greatly improve the efficiency of pipeline handling.
