Description

Technical Field

[0001] This utility model relates to the field of transformer installation, specifically a slide rail device for positioning a main transformer. Background Technology

[0002] The main transformer positioning slide rail is a special translation tool used for the installation of large power transformers. It is usually composed of high-strength steel rails, roller groups, traction system and fixed brackets. Its core function is to move transformers weighing tens to hundreds of tons to the foundation position in a limited space through a low-friction rolling or sliding mechanism. The slide rail system needs to be used in conjunction with a hydraulic propulsion device or a hand-operated hoist to apply force. It can effectively solve the problem of precise positioning of heavy equipment in narrow substations. Compared with traditional hoisting, it is safer and more efficient, and is especially suitable for indoor installation or operation scenarios that cannot be covered by cranes.

[0003] Existing slide rails for main transformer installation are usually composed of multiple sections of guide rail spliced ​​together. However, in actual use, due to the lack of effective auxiliary docking and positioning structures between adjacent guide rails, it is difficult to align them quickly and accurately during installation. The levelness of the guide rail joints is difficult to guarantee. Especially under heavy transformer loads, the guide rail joints that are not fully matched may cause local stress concentration, increase frictional resistance, or even cause jamming. This makes it difficult for the overall straightness and levelness of the slide rail system to meet the required accuracy, increasing the risk of displacement when the transformer is in place.

[0004] In summary, to improve the efficiency and accuracy of main transformer slide rail installation, it is necessary to address the issues of lack of positioning structure and difficulty in ensuring levelness when connecting multiple rail sections. This will enable adjacent rails to align quickly and accurately, ensuring the overall straightness and stability of the slide rail system, thereby reducing the risk of transformer misalignment during installation and improving the safety and reliability of heavy equipment installation. Utility Model Content

[0022] The present invention will be further described below with reference to specific embodiments.

[0023] Refer to the instruction manual appendix Figures 1 to 5A sliding rail device for positioning a main transformer includes a guide rail 1, a moving mechanism for supporting the main transformer, and an adjusting mechanism for adjusting the height. A rod 4 is fixed to one end of the guide rail 1, and a slot 5 is opened at the other end. An assembly groove 6 is opened on the guide rail 1, and a cover plate 7 is fixed to the guide rail 1 at a position corresponding to the assembly groove 6. A spring 8 is installed inside the assembly groove 6, and a push block 9 is fixed to the end of the spring 8. A fixing plate 10 is fixed to the push block 9. A limit rod 11 is fixed inside the assembly groove 6, and the fixing plate 10 and the limit rod 11 are slidably connected through it. A guide rod 12 is installed on the push block 9. A rubber block 13 is slidably connected inside the assembly groove 6, and a through groove 14 is opened on the rubber block 13, which slidably engages with the guide rod 12. A cam 15 is rotatably connected inside the assembly groove 6, and a rotating shaft 16 is fixed to the cam 15. A damping collar 17 is embedded in the cover plate 7, and the rotating shaft 16 is rotatably connected to the damping collar 17.

[0024] It should be noted that after the adjacent guide rail 1 is initially connected to the slot 5 via the insertion rod 4, the rotating shaft 16 drives the cam 15 to rotate. The cam 15 presses the push block 9 to overcome the resistance of the spring 8 and moves along the direction of the limit rod 11. The push block 9 drives the guide rod 12 to move. The guide rod 12 drives the rubber block 13 to slide in the assembly slot 6 through the through groove 14 that slides with it. The rubber block 13 finally tightly presses the insertion rod 4 of the adjacent guide rail 1 that has been inserted into the slot 5, achieving precise positioning and firm locking. The damping collar 17 provides rotational damping to ensure that the position of the cam 15 is stable, thereby ensuring that the guide rail 1 is connected quickly, accurately and reliably.

[0025] Refer to the instruction manual appendix Figure 1 and Figure 4 The moving mechanism includes a sliding component disposed on the outside of the guide rail 1, an adjusting component disposed on the sliding component, and a positioning component disposed on the adjusting component. The sliding component is used to drive the main transformer to move, the adjusting component is used to adjust the spacing between the positioning components, and the positioning component is used to position the main transformer.

[0026] It should be noted that the moving mechanism enables the main transformer to slide smoothly along the guide rail 1 through the sliding component. The adjustable component can flexibly adjust the distance between the positioning components on both sides to adapt to the installation requirements of main transformers of different sizes. The positioning component directly contacts and fixes the position of the main transformer to ensure its stability during the sliding and positioning process.

[0027] Refer to the instruction manual appendix Figure 1 and Figure 4 The sliding assembly includes a slide block 21 slidably connected to the guide rail 1, a plurality of fixed seats 22 fixed on the slide block 21, and a roller 23 rotatably connected to the fixed seats 22. The roller 23 cooperates with the guide rail 1.

[0028] It should be noted that the rolling of the roller 23 on the guide rail 1 positions the slide 21, enabling the slide 21, which carries the main transformer, to move smoothly and providing a basis for the translation of the transformer.

[0029] Refer to the instruction manual appendix Figure 4 The pitch adjustment assembly includes a mounting groove 24 on the slide 21, a bidirectional lead screw 25 rotatably connected inside the mounting groove 24, a knob 26 fixed to the end of the bidirectional lead screw 25, and a movable seat 27 threaded through and connected to the outside of the bidirectional lead screw 25. The knob 26 is used to drive the bidirectional lead screw 25 to rotate.

[0030] It should be noted that by rotating the knob 26 to drive the bidirectional lead screw 25 to rotate, the movable seats 27 symmetrically distributed at both ends of the lead screw move synchronously towards or away from each other, thereby precisely adjusting the spacing of the positioning components installed on the movable seats 27.

[0031] Refer to the instruction manual appendix Figure 4 The positioning component includes a positioning seat 28 fixed on the movable seat 27 and a protective pad 29 disposed on the positioning seat 28. The protective pad 29 is bonded and fixed to the positioning seat 28.

[0032] It should be noted that the positioning seat 28 provides rigid support, while the protective pad 29 on it directly contacts the main transformer body, providing buffer protection while positioning to prevent damage to the equipment surface.

[0033] Refer to the instruction manual appendix Figure 1 and Figure 5 The adjustment mechanism includes a lifting component mounted on the guide rail 1 and a support component mounted on the lifting component. The lifting component is used to drive the support component to rise and fall, and the support component is used to adjust the height of the guide rail 1.

[0034] It should be noted that the adjustment mechanism provides vertical height adjustment power through the lifting component, which drives the support component to rise and fall, ultimately achieving fine adjustment of the installation height of the entire guide rail 1, reducing the height error of the sleepers below, and ensuring that the guide rail 1 is level.

[0035] Refer to the instruction manual appendix Figure 1 and Figure 5 The lifting assembly includes two through holes 31 that are opened through the guide rail 1, a screw 32 that is set inside the through holes 31, and a hexagonal groove 33 opened at the top of the screw 32. The screw 32 is threadedly connected to the through holes 31.

[0036] It should be noted that the screw 32 can be driven to move vertically up and down relative to the guide rail 1 by rotating the screw 32.

[0037] Refer to the instruction manual appendix Figure 5 The support assembly includes a washer 34 disposed at the bottom end of the screw 32, and the washer 34 is rotatably connected to the screw 32.

[0038] It should be noted that the design of the rotatable connection of the shim 34 allows the shim 34 to remain stationary when the screw 32 is raised and lowered, avoiding frictional displacement with the ground and ensuring adjustment stability.

[0039] Working principle: Adjacent guide rails 1 are initially connected by inserting the rod 4 at one end into the slot 5 at the other end. Subsequently, the operator rotates the shaft 16 on the guide rail 1, causing the cam 15 fixed thereto to rotate. The rotating cam 15 presses against the push block 9, causing it to overcome the resistance of the spring 8 and slide along the direction of the fixed limit rod 11. The push block 9 drives the guide rod 12 on it to move. The guide rod 12, through sliding engagement with the through groove 14 on the rubber block 13, drives the rubber block 13 to slide within the assembly groove 6. Finally, the rubber block 13 tightly presses against the rod 4 of the adjacent guide rail 1 that has been inserted into the slot 5, achieving precise positioning and secure locking. The damping collar 17 provides rotational damping for the shaft 16. To prevent the cam 15 from accidentally returning to its original position and to ensure a stable locking state, the main transformer is placed on the slide 21. The slide 21 moves horizontally on the guide rail 1 by rolling the roller 23 on its fixed seat 22. By rotating the knob 26, the bidirectional lead screw 25 is driven to rotate, which can drive the symmetrical moving seats 27 to move towards or away from each other, thereby adjusting the distance between the positioning seat 28 and its protective pad 29 fixed on the moving seat 27 to adapt to transformers of different sizes and provide positioning protection. When it is necessary to adjust the height of the guide rail 1, the hexagonal groove 33 at the top of the screw 32 is rotated with a tool. The screw 32 rotates and rises and falls in the through hole 31, driving the pad 34 connected to its bottom end to rotate and support it on the sleeper, thereby achieving fine adjustment of height and level correction.
