Description

Technical Field

[0001] The present invention relates to the technical field of equipment installation, and specifically to a method for installing a transformer in a narrow and low space. Background Art

[0002] In metallurgical construction projects, in order to meet production requirements, a substation is usually set up to install transformers. Due to the compact process layout, there is less available space, and the transformers are all installed inside narrow and low spaces. During construction, it is very difficult to lift the transformer in place with a crane, and it is necessary to use a hydraulic flatbed truck for transfer. There are relatively large potential safety hazards during the transfer process. Moreover, due to the large weight of the transformer and the extremely narrow space, it is very difficult to carry out installation and adjustment operations. Summary of the Invention

[0003] The purpose of the present invention is to overcome the above defects and propose a method for installing a transformer in a narrow and low space that is easy to implement and can save installation steps.

[0004] A method for installing a transformer in a narrow and low space includes

[0005] Step 1: Construction of embedded part installation;

[0006] During the construction stage of the building foundation, the embedded parts required for transformer installation are pre-installed and fixed. Pay attention to checking the spacing and levelness during installation;

[0007] Step 2: Masonry of structural walls;

[0008] Step 2.1: After the construction of the building foundation is completed, carry out the masonry of the building walls. During the masonry process, for the walls facing the door, the first 6 bricks starting from the ground level need to be masonry with solid concrete bricks;

[0009] Step 2.2: Embed a hook at a height of 350 mm from the ground level on the central axis of the slide rail for installing the transformer base. The hook is located on the wall facing the door;

[0010] Step 2.3: The masonry of other parts of the wall is carried out using aerated concrete blocks;

[0011] Step 3: Installation of the base slide rail;

[0012] Step 3.1: After the wall masonry and plastering are completed, carry out the laying work of the slide rail for installing the transformer base;

[0013] Step 3.2: The installation slide rail is directly welded and fixed to the embedded part described in Step 1. Before welding and fixing, adjust the center distance and levelness of the two sides of the slide rail. Among them, the slide rail should extend at least 2.5 meters out of the structural surface, and the overhanging section of the slide rail is supported and fixed firmly with a bracket below the slide rail;

[0014] Step 4: Transformer installation;

[0015] Step 4.1: Hoist the transformer onto the cantilever section of the slide rail;

[0016] Step 4.2: Hook one end of the chain block in a figure-eight shape to the hook at the bottom of the transformer itself, and hook the other end of the chain block to the pulling hook described in Step 2;

[0017] Step 4.3: Manually pull the chain block to make the transformer slide on the slide rail until it slides to the designed position; during the process, pay attention that the center line of the transformer should coincide with the center line of the slide rail, and pay attention to controlling the sliding speed to avoid the overturning of the transformer;

[0018] Step 4.4: After sliding in place, remove the chain block, cut off the cantilever section of the slide rail, and directly use the indoor part of the slide rail as the base of the transformer. Weld the base of the transformer itself to the slide rail to complete the transformer installation work.

[0019] The method for sliding and installing a transformer in a narrow and low space proposed by the present invention enables the installation operation of the transformer to slide into place at one time by laying tracks and adopting the method of sliding operation, achieving the effect that the installation is completed when sliding into place, effectively improving the installation efficiency and reducing the safety risk of repeated handling. At the same time, there is no need for secondary leveling after installation, which saves time and effort, saves the cost of the transformer base frame, and has a certain height from the ground surface, which is beneficial to moisture-proof and heat dissipation. Description of the Drawings

[0020] Figure 1 It is a process schematic diagram of the method for sliding and installing the transformer shown in the present invention. Detailed Embodiments

[0021] The present invention will be further described below through specific embodiments.

[0022] As Figure 1 shown, a method for installing a transformer in a narrow and low space includes

[0023] Step 1: Embedded part installation construction;

[0024] During the construction stage of the building foundation, pre-install and fix the embedded parts required for the transformer installation. Pay attention to checking the spacing and levelness during installation;

[0025] Step 2: Structural wall masonry;

[0026] Step 2.1: After the construction of the building foundation is completed, carry out the masonry of the building wall. During the masonry process, for the wall facing the door, the first 6 bricks from the ground level upwards need to be masonry with solid concrete bricks;

[0027] Step 2.2: Embed the hook 1 at a height of 350 mm above the ground plane along the central axis of the slide rail 2 for the installation of the transformer base. The hook 1 is located on the wall on the side opposite the door.

[0028] Step 2.3: Use aerated concrete blocks for masonry of the walls in other parts.

[0029] Step 3: Installation of the slide rail 2 of the base.

[0030] Step 3.1: After the wall masonry and plastering are completed, carry out the laying work of the slide rail 2 for the installation of the transformer base.

[0031] Step 3.2: The installed slide rail 2 is directly welded and fixed to the embedded part described in Step 1. Before welding and fixing, adjust the center distance and levelness of the two slide rails 2. Among them, the slide rail should extend at least 2.5 meters beyond the structural surface, and the overhanging section of the slide rail is supported and fixed firmly with brackets below the slide rail.

[0032] Step 4: Installation of the transformer.

[0033] Step 4.1: Hoist the transformer 3 onto the overhanging section of the slide rail 2.

[0034] Step 4.2: Hook one end of the chain block 4 in a figure-eight shape to the hook at the bottom of the transformer itself, and hook the other end of the chain block to the hook described in Step 2.

[0035] Step 4.3: Manually pull the chain block to make the transformer slide on the slide rail until it slides to the designed position. During the process, pay attention that the center line of the transformer should coincide with the center line of the slide rail, and pay attention to controlling the sliding speed to avoid the overturning of the transformer.

[0036] Step 4.4: After sliding in place, remove the chain block, cut off the overhanging section of the slide rail, and the slide rail in the indoor part is directly used as the base of the transformer. Weld the base of the transformer itself to the slide rail to complete the installation work of the transformer.

[0037] The method for sliding installation of a transformer in a narrow and low space proposed by the present invention enables the installation operation of the transformer to slide into place at one time by laying tracks and using the sliding operation method, achieving the effect of being installed in place as soon as it slides into place. It effectively improves the installation efficiency and reduces the safety risks of repeated handling. At the same time, there is no need for secondary leveling after installation, which saves time and effort, saves the cost of the transformer base frame, and has a certain height from the ground surface, which is beneficial to moisture-proof and heat dissipation.
