Description

Technical Field

[0001] This invention relates to the field of power equipment installation and construction technology, specifically to a transformer track installation system and its construction method suitable for confined spaces. Background Technology

[0002] As a core component of the power system, the accuracy and stability of transformer installation directly affect the safety and stable operation of the power grid. Traditionally, transformer installation often involves using cranes for hoisting. However, this method has significant limitations in confined spaces such as indoors, enclosed factory buildings, or densely populated industrial sites (e.g., thermal power plants). Hoisting operations not only require the movement of large hoisting equipment, but also present challenges in coordinating the use of hoisting equipment when space is limited, the roof is enclosed, or other large equipment (e.g., steam turbines) is being installed on-site. This leads to complex scheduling, high safety risks, and difficulties in coordinating the use of hoisting equipment.

[0003] In the prior art, for example, the patent with authorization announcement number CN119153200A discloses a transformer installation device for photovoltaic power generation, which uses screws and nuts to fix an arc-shaped sleeve to a concrete pole to clamp and fix the transformer. This device relies on external concrete poles and other structures, and the arrangement of the winch also requires a certain amount of space. It is also difficult to solve the problem of accurately positioning and installing the transformer indoors or in a closed, narrow space without suitable fixing points.

[0004] Therefore, there is an urgent need for an installation solution that can adapt to complex space constraints and achieve stable, precise, and safe movement and positioning of transformers without relying on top hoisting. Summary of the Invention

[0005] In order to overcome the shortcomings of the existing technology, the present invention aims to provide a transformer track installation system and its construction method suitable for confined spaces. The system and method, through an adjustable track support structure and a dedicated hand-cranked moving platform, realize the smooth, controllable and precise movement and installation of transformers in confined spaces, which significantly improves construction safety and efficiency.

[0006] Firstly, to achieve the above objectives, the present invention adopts the following technical solution: a transformer rail installation system suitable for confined spaces, used for moving and installing transformers within confined spaces, characterized in that it comprises: a foundation platform, on which two parallel installation rails are provided; multiple height-adjustable support columns, which are arranged below the installation rails; a moving platform for supporting the transformer, the bottom of which is provided with rollers that slide in cooperation with the installation rails for supporting the transformer; and a hand-cranked drive device, which is detachably connected to the installation rails via a clamp, the output end of the hand-cranked drive device being connected to the moving platform.

[0007] This invention constructs an integrated track-driven system specifically for the horizontal movement of heavy equipment. The system uses two parallel installation tracks as the core guide path, with multiple height-adjustable support columns securing and leveling the tracks to form a rigid reference plane aligned with the target position. The moving platform is supported on these tracks by rollers at its bottom, used to fix and support the transformer. The key to achieving this drive is that the hand-cranked drive device is not placed independently or simply pushed, but rather its body is detachably anchored to the stationary installation track via a dedicated clamp, while its output end is connected to the moving platform. When the hand-cranked drive device is operated, because its body is rigidly connected to the track via the clamp, the reaction force generated by the device is completely absorbed by the track system. This efficiently, directly, and smoothly transmits all the output thrust or traction force to the moving platform, driving the platform and transformer to move precisely and controllably along the track to the predetermined position.

[0008] This technical solution has yielded the following significant benefits: First, it completely eliminates the reliance on overhead hoisting space and large hoisting machinery. By constructing a track system on the ground, it perfectly solves the technical challenge of installing heavy transformers in confined spaces such as indoors, already enclosed spaces, or areas with dense equipment. Second, due to the extremely stable drive fulcrum (clamps and tracks) and the direct transmission of driving force through a rigid structure, the entire movement process is smooth, without backlash or swaying, achieving millimeter-level micro-motion control of heavy-duty equipment. Its safety and positioning accuracy far surpass traditional hoisting or simple sliding methods. Finally, the system's tracks, columns, platforms, and drive units can all be standardized and reused. This not only allows for flexible installation and adjustment to adapt to different site conditions but also provides convenient access for subsequent equipment maintenance and replacement, comprehensively reducing construction costs and complexity.

[0009] Preferably, as an improvement, the clamp is a clamp-type clamp or a jig-type clamp, which has a groove adapted to the profile of the mounting rail and is fixed to the mounting rail by bolts. This clamp or jig structure is a connector that is easily designed by those skilled in the art based on commonly used rail profiles (such as I-beam flanges). Its "special design" is mainly reflected in its adaptability to specific rail cross-sections and the connection interface of the hand-cranked drive device. Using this structure, the clamp can provide a rigid anchor point, and the installation position can be flexibly adjusted along the rail as needed.

[0010] Preferably, as an improvement, the hand-cranked drive device is a hand-cranked screw jack or a hand-cranked winch. Both are mature manual linear or traction drive tools. When a hand-cranked screw jack is selected, its housing is fixed by a clamp, the jack rod is connected to the platform, and the jack rod is extended by cranking the rocker arm to push the platform forward. When a hand-cranked winch is selected, its body is fixed by a clamp, the wire rope traction end is connected to the platform, and the platform is pulled forward by winding the wire rope. Together, they provide a controllable, smooth, and labor-saving driving force.

[0011] Preferably, as an improvement, sleepers are provided between the bottom of the supporting column and the foundation platform. This structure enhances the stability and vibration damping of the entire support system.

[0012] Preferably, as an improvement, the cross-section of the mounting track is I-shaped or grooved. This structure uses industrial standard profiles, has high strength, and is easy to connect with clamps and support structures.

[0013] Preferably, as an improvement, the bearing surface of the mobile platform is provided with a connection structure for connecting to the transformer base.

[0014] Secondly, the present invention also provides a transformer rail installation method using the system, comprising the following steps: S1. Preparation: Set up foundation platforms at the starting and target positions of the transformer, and prepare to install the rails, support columns, moving platform, clamps and hand-cranked drive device. S2. Install and level the support columns: Install the support columns according to the design location and adjust their height so that the top surfaces of all support columns are on the same horizontal plane; S3. Lay the installation track: Fix the installation track to the top of the leveled support column; S4. Assemble the drive and support unit: Place the mobile platform on the installation rail; install and fix the clamp at the predetermined position on the installation rail; fix the body of the hand-cranked drive device to the clamp, and connect the output end of the hand-cranked drive device to the mobile platform; S5. Connect the transformer: Fix the transformer to the bearing surface of the mobile platform; S6. Moving Transformer: Operate the hand-cranked drive device to drive the moving platform carrying the transformer to move smoothly along the installation track to the top of the target foundation.

[0015] Preferably, as an improvement, in step S4, the clamp is a clamp-type clamp, which is locked to the wing plate of the mounting track by tightening the bolts on it; the hand-cranked drive device is a hand-cranked screw jack, the base of which is connected to the clamp-type clamp by bolts, and its top rod is connected to the moving platform by a connecting pin.

[0016] Preferably, as an improvement, before step S6, a simulation test step is also included: loading a counterweight similar in weight to the transformer onto the mobile platform, operating the hand-cranked drive device to perform a full-process movement test, and verifying the system stability.

[0017] Preferably, as an improvement, the hand-cranked drive device is a hand-cranked winch. In step S4, the body of the hand-cranked winch is fixed on the installation rail by a clamp, and the wire rope traction end of the winch is connected to the mobile platform. Attached Figure Description

[0020] The following detailed description illustrates the specific implementation method: like Figures 1 to 4 As shown, this embodiment provides a transformer track installation system suitable for confined spaces. The system mainly includes an installation track 2, a support column 5, a moving platform 3, a clamp 6, and a hand-cranked screw jack 7.

[0021] Hand-cranked drive device (in this embodiment, a hand-cranked screw jack): Its core function is to provide controllable, stable, and self-locking linear thrust or traction. In this system, it replaces the vertical lifting and traction function of the crane, achieving precise movement of heavy objects by directly applying force in the horizontal direction. In addition to the screw jack used in this embodiment, a hand-cranked winch (pulled by a wire rope) or other manual, even electrically controlled or hydraulic drive devices that can provide stable linear output can also be selected according to site needs and tonnage requirements, as long as they can meet the installation requirement of "one end fixed, one end output drive".

[0022] Clamp 6 (in this embodiment, it is a clamp type): Its core function is to serve as a movable rigid anchor point, providing a stable support foundation for the hand-cranked drive device. It reliably transmits the reaction force of the drive device to the mounting rail 2 and the entire support system. Its specific form is not limited to a clamp; it can also be a fixture, a welded part with ear plates, or a connecting block specially made according to the rail cross-section, etc. The key is to achieve a firm lock with the rail profile and a convenient connection with the drive device body.

[0023] The specific installation method is as follows: I. Preparatory Work Prepare the following: 1. Designed I-beams as installation rails; 2. Support columns with adjusting screws; 3. Mobile platform with heavy-duty rollers at the bottom; 4. Clamping clamps; 5. Hand-cranked screw jacks with a rated thrust greater than the weight of the transformer; 6. Several sleepers.

[0024] II. Installation and Leveling of Support Columns 5 On the foundation platform 1 at the starting end and the foundation platform 9 at the target end, install supporting columns 5 at the designed spacing. Use a level to precisely adjust the top surface height of each column 5 to ensure that they are on the same horizontal plane. To enhance overall stability and distribute the load, place sleepers 8 under the base plate of each column 5.

[0025] III. Laying and installing the track 2 Two I-beam rails 2 are hoisted to the top of the leveled column 5. After correcting their parallelism and straightness, high-strength bolts are used to fasten the rails 2 to the column 5.

[0026] IV. Assembly of Drive and Load-Bearing Units Place the mobile platform 3 on the mounting rail 2. Determine the initial installation position of the clamp-type fixture 6 on the rail 2 according to the drive stroke plan. Insert the slot of the fixture 6 into the lower flange of the I-beam rail, and then tighten the fastening bolts on its side to secure it firmly to the rail 2. Next, fix the base of the hand-cranked jack 7 to the pre-installed connecting plate on the clamp-type fixture 6 using bolts. Finally, use connecting pins to hinge the end of the jack 7's push rod to the connecting lug at the rear of the mobile platform 3.

[0027] V. Connecting Transformer 4 Use small auxiliary lifting equipment to hoist the transformer 4 onto the bearing surface of the mobile platform 3, and use the connection holes or pressure plates on the platform to fasten the base of the transformer 4 to the platform 3.

[0028] VI. (Optional) Simulation Test Before the formal movement, a counterweight of equal weight can be placed on platform 3 to conduct a full round-trip movement test to check for track deformation, loose connection points, smooth drive, and other issues, ensuring that the system is absolutely reliable.

[0029] VII. Transformer relocation and positioning The operator simultaneously cranks the levers at both ends of jack 7, causing the levers to extend at a uniform speed. Since the jack housing is rigidly fixed to the track 2 by clamps 6, the thrust generated by the levers is fully applied to the moving platform 3, thus propelling the transformer 4 forward smoothly. During movement, cranking can be stopped at any time, and the system will automatically lock in position. The moving distance can be precisely controlled by adjusting the number of cranking rotations. Once the transformer 4 is pushed directly above the target foundation platform 9, its connection to the moving platform 3 is released. The transformer height is then fine-tuned using jacks or other lifting tools, the track system is removed, and the transformer installation is finally complete.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solutions of the present invention, and these should also be considered within the scope of protection of the present invention.
