Description

Technical Field

[0001] This utility model relates to the field of thermal power plant equipment technology, specifically to a cold-state pre-adjustment positioning and locking structure for spring supports in thermal power plants. Background Technology

[0002] In the production and operation of thermal power plants, the pipeline system is the key carrier for the transmission of working fluids, and spring supports, as the core components supporting and suspending pipelines, play a crucial role in the stable operation of the pipeline system. Spring supports need to be pre-adjusted in a cold state (i.e., when the pipeline is not in operation and is at room temperature) according to the pipeline's design parameters and operating conditions. This ensures that in a hot state (when the pipeline is running, due to the increased temperature of the working fluid causing pipeline expansion), they can provide appropriate support or suspension force to the pipeline, ensuring that the pipeline's position and stress are within a reasonable range. This prevents deformation and damage to the pipeline due to improper stress, thereby ensuring the safe and stable operation of the overall thermal power plant equipment.

[0003] However, most existing spring supports lack an effective locking structure after cold pre-adjustment. In the actual construction and operation environment of thermal power plants, many factors can easily cause spring supports to shift. For example, during pipeline installation, collisions between pipes are inevitable, and the resulting external forces act on the spring supports, altering their pre-adjusted positions. Additionally, during the transportation of thermal power plant equipment, the vibrations generated by vehicles continuously affect the spring supports, causing them to gradually deviate from their correct pre-adjusted positions. Once the spring supports shift, the previous cold pre-adjustment becomes ineffective. At this point, to ensure the normal operation of the pipeline system, the spring supports need to be readjusted, increasing construction costs and impacting the construction schedule.

[0004] To address this, a cold-state pre-adjustment positioning and locking structure for spring supports in thermal power plants is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a cold-state pre-adjustment positioning and locking structure for spring supports in thermal power plants, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A cold-state pre-adjustment positioning and locking structure for a spring support hanger in a thermal power plant includes a base for fixing and installing the overall device, and a locking and fitting block for locking the pre-adjustment position. The top of the base is fixedly provided with a main spring support hanger component that provides support and buffering functions. The main spring support hanger component is equipped with a stabilizing guide component to prevent component displacement. A pre-adjustment component for realizing cold-state pre-adjustment is provided on the outer side of the main spring support hanger component. The pre-adjustment component has an adjustment hole for easy tool insertion. A moving component for driving the locking and fitting block is connected between the main spring support hanger component and the locking and fitting block. The contact surface of the locking and fitting block is coated with an anti-slip coating to enhance friction. The outer wall of the main spring support hanger component is engraved with scale lines to assist in observing the pre-adjustment amount.

[0008] Furthermore, the main body assembly of the spring support includes a sleeve, the surface of the base is fixedly connected to the sleeve, and the scale lines are set on the surface of the sleeve. The top surface of the sleeve is fixedly connected to a connecting block, the bottom inner wall of the connecting block is fixedly connected to a spring body, the end of the spring body away from the bottom inner wall of the sleeve is fixedly connected to a moving block, the top surface of the moving block is fixedly connected to a load-bearing rod, and the load-bearing rod is movably inserted into the connecting block. The end of the load-bearing rod away from the moving block is fixedly connected to a top block.

[0009] Furthermore, the stabilizing guide assembly includes a guide groove, the inner wall of the sleeve is provided with a guide groove, the surface of the moving block is fixedly connected to a guide block, and the guide block is slidably connected to the guide groove, which can restrict the moving block to move only in the vertical direction and avoid horizontal deviation.

[0010] Furthermore, the pre-adjustment component includes a pre-adjustment screw, the bottom surface of the connecting block is fixedly connected to the pre-adjustment screw, and the end of the pre-adjustment screw away from the connecting block is fixedly connected to the base. A pressing block is movably sleeved on the surface of the load-bearing rod. An opening is formed through the surface of the pressing block, and the pressing block is movably sleeved with the pre-adjustment screw through the opening. The opening is in contact with the moving block. A pre-adjustment nut is threadedly connected to the surface of the pre-adjustment screw.

[0011] Furthermore, the movable component includes a movable screw, the movable screw is rotatably connected to the surface of the locking and fitting block, and the movable screw is threadedly connected to the sleeve. A guide rod is fixedly connected to the surface of the locking and fitting block, and the guide rod is movably inserted into the sleeve. A rotating handle is fixedly connected to the end of the movable screw away from the locking and fitting block.

[0012] Furthermore, the adjustment holes are formed on the surface of the pre-adjusting nut, and the adjustment holes are distributed in a circular array around the center of the pre-adjusting nut. The hole diameter is adapted to the size of commonly used wrenches or adjustment rods, making it convenient to insert tools to rotate the pre-adjusting nut.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. After pre-adjustment, rotating the handle drives the moving screw to rotate. Guided by the guide rod, the locking block moves towards the load-bearing rod and fits tightly. The anti-slip coating on the surface of the locking block increases the friction with the load-bearing rod, effectively locking the load-bearing rod and preventing external factors such as pipeline installation collisions and equipment transportation vibrations from causing the spring support to shift position, ensuring a long-lasting and stable pre-adjustment effect. Because it effectively locks the pre-adjusted spring support, it avoids the need for readjustment due to positional shifts, reducing additional manpower and material resources and lowering construction costs. Simultaneously, it ensures the progress of pipeline system installation and commissioning, thus preventing construction progress from being affected by pre-adjustment failure.

[0015] 2. Using the adjustment hole, the pre-adjustment nut can be easily turned with a wrench or other tools, causing it to rotate on the pre-adjustment screw and move the compression block. This compression of the moving block achieves pre-compression of the spring body, completing the cold pre-adjustment. Simultaneously, the scale lines allow operators to clearly observe the degree of pre-adjustment during the process and accurately control the amount of pre-adjustment. The moving block slides within the guide groove via a guide block, which guides and stabilizes its movement, preventing deviation and ensuring stable operation of the spring support during operation.

[0027] like Figure 1-6As shown, a cold-state pre-adjustment positioning and locking structure for a spring support in a thermal power plant includes a base 1 and a locking and fitting block 6. A spring support main assembly 2 is mounted on the surface of the base 1. A stabilizing guide assembly 3 is mounted on the spring support main assembly 2. A pre-adjustment assembly 4 is mounted on the spring support main assembly 2, and an adjustment hole 5 is provided on the surface of the pre-adjustment assembly 4. Moving components 7 for moving the locking and fitting block 6 are provided on the surfaces of the spring support main assembly 2 and the locking and fitting block 6. An anti-slip coating 8 is applied to the surface of the locking and fitting block 6. Scale lines 9 are provided on the surface of the spring support main assembly 2. Specifically, the base 1 is made of steel plate and has symmetrically distributed mounting holes at its bottom for easy fixing to the ground or equipment foundation using expansion bolts, ensuring the overall structure is installed stably. The locking and fitting block 6 has an arc-shaped structure, the curvature of which matches the outer wall curvature of the spring support main assembly 2, enabling a tight fit between the components and avoiding locking failure caused by uneven local stress.

[0028] like Figure 1 , Figure 4 , Figure 5 As shown, the main component 2 of the spring support includes a sleeve 201. The sleeve 201 is fixedly connected to the surface of the base 1, and a scale line 9 is set on the surface of the sleeve 201. A connecting block 202 is fixedly connected to the top surface of the sleeve 201. A spring body 203 is fixedly connected to the bottom surface of the inner wall of the connecting block 202. A moving block 204 is fixedly connected to the end of the spring body 203 away from the bottom surface of the inner wall of the sleeve 201. A load-bearing rod 205 is fixedly connected to the top surface of the moving block 204, and the load-bearing rod 205 is movably inserted into the connecting block 202. A top block 206 is fixedly connected to the end of the load-bearing rod 205 away from the moving block 204. Specifically, the sleeve 201 is a seamless steel pipe structure to ensure its strength. The spring body 203 is made of high-temperature resistant alloy. Made of high-temperature spring steel, it can adapt to the high-temperature operating environment of thermal power plants. Its elastic coefficient is preset according to the pipeline design load to ensure that it can provide stable support for the pipeline. The moving block 204 is connected to the load-bearing rod 205 on the top and the spring body 203 on the bottom. It can evenly transmit the load transmitted by the pipeline through the load-bearing rod 205 to the spring body 203, avoiding uneven force on the spring body 203. At the same time, during the cold pre-adjustment process, the moving block 204 can move along the inner wall of the sleeve 201 with the squeezing action of the pre-adjustment component 4, driving the load-bearing rod 205 to adjust the height, thereby realizing the adjustment of the pre-compression of the spring body 203, providing a suitable support height for the cold installation of the pipeline. The top block 206, as the component in direct contact with the pipeline, provides a stable support foundation for the pipeline.

[0029] like Figure 4 , Figure 5As shown, the stabilizing guide assembly 3 includes a guide groove 301. The inner wall of the sleeve 201 is provided with the guide groove 301. A guide block 302 is fixedly connected to the surface of the moving block 204, and the guide block 302 is slidably connected to the guide groove 301. Specifically, the guide groove 301 is opened along the height direction of the sleeve 201, and its length is consistent with the effective height of the sleeve 201, ensuring that the moving block 204 can be guided within its maximum stroke. The guide block 302 is fixed to the moving block 204 by welding, and its surface can be inlaid with a polytetrafluoroethylene wear-resistant sheet. The wear-resistant sheet fits against the inner wall of the guide groove 301, which can reduce sliding friction resistance, reduce component wear, and extend service life.

[0030] like Figure 2 , Figure 4 , Figure 5 As shown, the pre-adjustment component 4 includes a pre-adjustment screw 401. The pre-adjustment screw 401 is fixedly connected to the bottom surface of the connecting block 202, and the end of the pre-adjustment screw 401 away from the connecting block 202 is fixedly connected to the base 1. A pressing block 402 is movably sleeved on the surface of the load-bearing rod 205. An opening 403 is provided through the surface of the pressing block 402, and the pressing block 402 is movably sleeved with the pre-adjustment screw 401 through the opening 403. The opening 403 is also in contact with the moving block 204. The pre-adjusting screw 401 is threaded with a pre-adjusting nut 404. Specifically, the pre-adjusting screw 401 is made of high-strength stainless steel and has fine threads machined on its surface, which can achieve fine adjustment of the pre-adjustment amount. The extrusion block 402 is a steel plate structure to ensure sufficient rigidity and avoid deformation during the extrusion process. The inner diameter of the opening 403 is matched with the outer diameter of the pre-adjusting screw 401 to ensure that the extrusion block 402 can move smoothly along the pre-adjusting screw 401 while avoiding radial wobbling.

[0031] like Figure 4 , Figure 6 As shown, the movable component 7 includes a movable screw 701, which is rotatably connected to the surface of the locking and fitting block 6 and threadedly connected to the sleeve 201. A guide rod 702 is fixedly connected to the surface of the locking and fitting block 6 and is movably inserted into the sleeve 201. A rotating handle 703 is fixedly connected to the end of the movable screw 701 away from the locking and fitting block 6. Specifically, the movable screw 701 and the sleeve 201 are connected by a trapezoidal thread, which has a self-locking function to prevent the screw from loosening due to vibration after locking. The guide rod 702 adopts a smooth shaft structure, and its fit clearance with the sleeve 201 is reasonable to ensure the stability of the locking and fitting block 6 when moving. The rotating handle 703 is covered with a rubber anti-slip sleeve to facilitate the operator to apply force.

[0032] like Figure 2As shown, adjustment holes 5 are opened on the surface of the pre-adjustment nut 404, and the adjustment holes 5 are distributed in a circular array around the center of the pre-adjustment nut 404; specifically, there are multiple adjustment holes 5, and the hole diameter is adapted to the insertion of commonly used hex wrenches or adjustment rods; at the same time, the outer wall of the pre-adjustment nut 404 can be provided with anti-slip texture, so that it can be rotated by hand without tools, improving the flexibility of operation.

[0033] In summary: The cold-state pre-adjustment positioning and locking structure of this thermal power plant spring support is used by first installing the device in a suitable position via the base 1. The top block 206 is used to support or suspend equipment such as pipes. During cold pre-adjustment, the pre-adjustment nut 404 is rotated using the adjustment hole 5 and a wrench or similar tool. The pre-adjustment nut 404 rotates and moves on the pre-adjustment screw 401, causing the compression block 402 to move. The compression block 402 compresses the moving block 204, compressing the spring body 203 and achieving pre-adjustment. The degree of pre-adjustment can be observed through the scale line 9 during the process. After pre-adjustment, the rotating handle 703 is rotated, causing the moving screw 701 to rotate. The moving screw 701 engages with the sleeve 201, causing the locking contact block 6 to move towards the load-bearing rod 205 under the guidance of the guide rod 702 until the locking contact block 6 is tightly fitted to the load-bearing rod 205. The anti-slip coating 8 increases friction, locking the load-bearing rod 205. When the spring support is in operation, the spring body 203 provides elastic support, and the moving block 204 slides in the guide groove 301 through the guide block 302 to ensure stable movement.
