Description

Technical Field

[0001] The utility model relates to the technical field of transformer cabinets, and more particularly to a transformer cabinet for convenient installation of transformers. Background Art

[0002] Before installation, the transformer cabinet is generally in a disassembled state. The disassembled transformer cabinet is more convenient to enter the substation room. During the assembly of the transformer cabinet, the transformer body is the largest component in the assembly process. During the assembly process, the cabinet body needs to be assembled before the transformer body is placed in the cabinet body. However, due to the large weight of the transformer body and the limited space inside the substation room, it is not convenient for large equipment to enter. Therefore, the common solution for moving the transformer body is to transport the transformer body by a cart.

[0003] After searching, the Chinese patent with announcement number CN210074494U discloses a distribution cabinet that facilitates the installation of transformers. A sliding screw drives the horizontal fixed row and the longitudinal fixed row in the middle. The horizontal fixed row and the longitudinal fixed row form a stable quadrilateral structure on which the transformer can be fixed. In this way, when the screw is rotated, the slider nut drives the transformer from the inside to the outside and moves the transformer to the front of the cabinet, making it easy to install or disassemble.

[0004] The drawback of the above-mentioned power distribution cabinet that facilitates transformer installation in actual use is that the transformer itself is heavy, and the method of rotating the nut to drive the screw to rotate is more time-consuming and labor-intensive, because the nut needs to be rotated a large number of times to complete the screw driving the transformer to the installation position inside the cabinet. At the same time, there is a lack of a buffering protection structure during the installation of the transformer. When the transformer is placed inside the cabinet, the distance between the interior and the inner wall of the cabinet cannot be seen, which makes it easy for collisions to occur and cause damage.

[0013] Beneficial effects of the utility model:

[0014] 1. By installing a guide rail seat with a rolling groove and providing a V-shaped opening at the end of the rolling groove, the entry position of the roller on the guide rail seat is widened, so that the operator does not need to align the roller with the position of the rolling groove little by little to lift and adjust the transformer. The operator only needs to place the roller in the V-shaped opening, and the front end of the transformer will be supported. The operator only needs to push and adjust the position of the transformer to conveniently place the roller at the bottom of the transformer inside the rolling groove, saving manpower and time.

[0015] 2. By setting a locking mechanism, during the installation of the transformer, the inclined portion at the end of the base vehicle first contacts the positioning post. In the process of pushing the transformer into the interior of the cabinet, due to the design of the inclined surface, the positioning post will be driven to descend and retract into the inside of the load-bearing plate, causing the movable plate to descend on the inner wall of the movable cavity. At this time, the first spring is compressed, the pull rod and the toggle block descend, and when the transformer is moved to the installation position, the positioning slot at the bottom of the base vehicle is placed above the positioning post. Since the positioning post is no longer under pressure, the first spring is reset to push the positioning post into the positioning slot at the bottom of the base vehicle to complete the locking, that is, the position of the transformer inside the cabinet is locked to prevent the transformer from moving and falling off inside the cabinet.

[0016] 3. By setting up a buffer mechanism, when the transformer is installed into the cabinet, it first contacts the buffer plate and drives the second spring to be continuously compressed, thereby avoiding a large force collision with the rear wall of the cabinet and playing a buffer protection role.

[0029] Working principle: This utility model designs a transformer cabinet that is convenient for installing transformers. The specific structure is as shown in the attached manual. Figure 1-5When the trolley 5 is lifted up, the roller 6 on the bottom of the transformer 4 is lifted to the height of the guide rail seat 3. The rolling groove 8 provided on the guide rail seat 3 can be used for the stable rolling of the roller 6 on the trolley 5 at the bottom of the transformer 4 and play a limiting role. By providing a V-shaped opening 7 at the end of the rolling groove 8, the entry position of the roller 6 on the guide rail seat 3 is widened, so that the operator does not need to align the roller 6 with the position of the rolling groove 8 to lift and adjust the transformer 4. The operator only needs to place the roller 6 in the V-shaped opening 7, and the front end of the transformer 4 is supported. The operator only needs to push and adjust the position of the transformer 4 to facilitate the roller 6 at the bottom of the transformer 4 to be placed in the rolling groove 7, saving manpower and time. The guide rail seat 3 is convenient for assembly and disassembly. After assembly, it is slidingly stuck in the inside of the load-bearing plate 2 and locked with the fastening bolts 9, so that the stability after assembly is strong and there is no position offset problem. By providing a locking mechanism, during the installation process of the transformer 4, the end inclined portion 22 of the trolley 5 first contacts the positioning column 10, and then pushes the transformer 4. During the movement toward the interior of the cabinet 1, due to the design of the inclined surface, the positioning column 10 will be driven to descend and retract into the interior of the load-bearing plate 2, causing the movable plate 12 to descend on the inner wall of the movable cavity 13. At this time, the first spring 14 is compressed, the pull rod 15 and the toggle block 16 descend, and when the transformer 4 is moved to the installation position, the positioning slot 11 at the bottom of the base vehicle 5 is placed above the positioning column 10. Since the positioning column 10 is no longer under pressure, the first spring 14 is reset and pushes the positioning column 10 into the positioning slot 11 at the bottom of the base vehicle 5 to complete the locking. The position of the transformer 4 inside the cabinet is locked to prevent the transformer 4 from moving and falling off inside the cabinet 1. When the transformer 4 needs to be removed, it is only necessary to pull the toggle block 16 downward to drive the pull rod 15, the movable plate 12 and the positioning column 10 to descend for quick disassembly. By setting up a buffer mechanism, it is convenient to first contact the buffer plate 20 during the process of installing the transformer 4 into the cabinet 1, and drive the second spring 21 to be continuously compressed, thereby avoiding a large force collision with the rear wall of the cabinet 1, thereby achieving a buffering and protective effect.
