Description

Technical Field

[0001] This utility model relates to the field of substation expansion technology, and in particular to a substation expansion equipment foundation structure that can be quickly assembled. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components include a primary coil, a secondary coil, and an iron core.

[0003] With the continuous development of the social economy, the demand for electricity is growing rapidly. To meet the ever-increasing demand, the expansion of substations has become more frequent and important. As one of the core pieces of equipment in a substation, the installation and support structure of the transformer plays a crucial role in the safe and stable operation of the entire substation.

[0004] In traditional substation expansion projects, the supporting foundation structure for transformer equipment is typically constructed using on-site cast-in-place concrete. However, during actual operation, due to varying equipment layout requirements, cable laying needs, or special circumstances such as site flooding, it is sometimes necessary to raise the transformer to a specific height. Once the foundation structure is built, its height is fixed. Adjusting the height usually requires dismantling the existing foundation and rebuilding, which not only consumes significant manpower, material resources, and financial resources but also greatly disrupts the normal operation of the substation.

[0005] Therefore, a substation expansion equipment foundation structure that can be quickly assembled is needed. Utility Model Content

[0006] The main objective of this invention is to provide a rapidly assembleable equipment foundation structure for substation expansion, which can effectively solve the problems mentioned above.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A rapidly assembleable substation expansion equipment foundation structure includes four support legs. Two of the support legs on the same side are fixedly connected to a connecting rod at their upper ends. The front and rear ends of the two connecting rods, which are close to each other, are fixedly connected to a telescopic mechanism. The rear upper ends of the two connecting rods are fixedly connected to a lifting device. A rectangular plate is fixedly connected to the upper part of the lifting device, and a support plate is fixedly connected to the lower front side of the lifting device.

[0009] Preferably, the telescopic mechanism includes two mounting plates, which are respectively mounted on the ends of the two connecting rods that are close to each other. The middle parts of the ends of the two mounting plates that are close to each other are respectively fixedly connected to a slide rail and a slide rod.

[0010] Preferably, the slide rod located on one side is slidably connected to the inner cavity of the slide rail, and the mounting plate is threadedly connected to the end face of the connecting rod.

[0011] Preferably, the lifting device includes two support rods, which are respectively fixedly connected to the upper rear parts of the two connecting rods. A connecting plate is fixedly connected to the two support rods at their adjacent ends. Guide rods are fixedly connected to the left and right sides of the adjacent ends of the connecting plate and the rectangular plate. Slider blocks are slidably connected to the lower parts of the outer surfaces of the two guide rods. Pulley mechanisms are fixedly connected to the upper front parts of the two support rods and the lower left and right sides of the rectangular plate. Triangular plates are fixedly connected to the middle sides of the left and right rear ends of the support plate.

[0012] Preferably, the support plate is fixedly connected to the front ends of the two sliders.

[0013] Preferably, the pulley mechanism includes an electric telescopic cylinder, which is fixedly connected to the front of the upper end of the support rod. An open plate is fixedly connected to both the output end of the electric telescopic cylinder and the lower end of the rectangular plate. Rollers are rotatably connected to the inner cavities of the two open plates, and a belt is wound around both rollers.

[0014] Preferably, one end of each of the two belts is fixedly connected to two triangular plates, and the other end of each of the two belts is fixedly connected to the lower end of a rectangular plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1.

Detailed Implementation

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Example 1, as Figure 1 and Figure 2 As shown, a substation expansion equipment foundation structure that can be quickly assembled includes four support legs 1. The upper ends of two support legs 1 located on the same side are fixedly connected to a connecting rod 2. The front and rear ends of the two connecting rods 2 that are close to each other are fixedly connected to a telescopic mechanism 3. The rear ends of the upper ends of the two connecting rods 2 are fixedly connected to a lifting device 5. A rectangular plate 6 is fixedly connected to the upper part of the lifting device 5. A support plate 4 is fixedly connected to the lower front side of the lifting device 5.

[0027] Both the support leg 1 and the connecting rod 2 of this device are hollow. This device is used to support the transformer.

[0028] Before implementing this device, firstly:

[0029] Weld the connecting rod 2 to the support leg 1, then thread one side of the telescopic mechanism 3 onto the connecting rod 2 on one side of the telescopic mechanism 3. Then, the worker connects the other side of the telescopic mechanism 3 to the connecting rod 2 with bolts. After the support leg 1, connecting rod 2 and telescopic mechanism 3 are connected, the worker can stretch the length of the telescopic mechanism 3 according to the size of the transformer to increase the distance between the two connecting rods 2. After adjustment, the worker fixes the support leg 1 to the ground with bolts. After the support leg 1 is fixedly installed, the worker then installs the lifting device 5, support plate 4 and rectangular plate 6 onto the support leg 1 with bolts, thus completing the installation of the device.

[0030] In the above description, the transformer is installed at a high position. When the transformer needs to be installed, it is first installed on the support plate 4, and then the lifting device 5 is started to move. When the lifting device 5 moves, it will drive the support plate 4 to move upward, raising the position of the transformer and moving it to the required position. Then the lifting device 5 is stopped, and the support plate 4 stops at the current position, so that the support plate 4 supports the transformer.

[0031] The design of this device during assembly reduces its footprint during transportation, making it more convenient to transport.

[0032] In a further embodiment, to achieve the purpose of adjusting the distance between the two connecting rods 2 after they are connected by the telescopic mechanism 3, please refer to... Figure 3 The telescopic mechanism 3 includes two mounting plates 31, which are respectively mounted on the two connecting rods 2 at their close ends. The middle part of the two mounting plates 31 at their close ends is respectively fixedly connected to a slide rail 33 and a slide rod 32.

[0033] Furthermore, the slide rod 32 located on one side is slidably connected to the inner cavity of the slide rail 33, and the mounting plate 31 is threadedly connected to the end face of the connecting rod 2.

[0034] In the above, through holes are provided at all four corners of the vertical surface of the mounting plate 31.

[0035] In the above, the mounting plate 31 is installed on the connecting rod 2 with bolts. When it is necessary to adjust the distance between the two connecting rods 2, only one side of the connecting rod 2 needs to be pulled. Then the sliding rod 32 will move together with the pulling of the connecting rod 2, so that the sliding rod 32 slides in the inner cavity of the slide rail 33, thereby increasing the distance between the two connecting rods 2. This allows the telescopic mechanism 3 to be adjusted according to the size of the transformer, achieving the purpose of rational space utilization.

[0036] Furthermore, in order to achieve the purpose of moving the support plate 4 upward when the lifting device 5 moves, refer to... Figure 4 , Figure 5 and Figure 6 The lifting device 5 includes two support rods 51, which are fixedly connected to the upper rear of the two connecting rods 2 respectively. The two support rods 51 are fixedly connected to a connecting plate 52 at their close ends. The left and right sides of the connecting plate 52 and the rectangular plate 6 are fixedly connected to guide rods 54. The lower outer surfaces of the two guide rods 54 are slidably connected to sliders 53. The front upper ends of the two support rods 51 and the left and right lower ends of the rectangular plate 6 are fixedly connected to pulley mechanisms 55. The left and right middle sides of the rear end of the support plate 4 are fixedly connected to triangular plates 56.

[0037] Furthermore, the support plate 4 is fixedly connected to the front end of the two sliders 53;

[0038] Furthermore, the pulley mechanism 55 includes an electric telescopic cylinder 551, which is fixedly connected to the front of the upper end of the support rod 51. An open plate 553 is fixedly connected to both the output end of the electric telescopic cylinder 551 and the lower end of the rectangular plate 6. Rollers 552 are rotatably connected to the inner cavities of the two open plates 553, and belts 554 are wound around the two rollers 552 together.

[0039] Furthermore, one end of each of the two belts 554 is fixedly connected to one of the two triangular plates 56, and the other end of each of the two belts 554 is fixedly connected to the lower end of the rectangular plate 6.

[0040] In the above, if the dimensions between the two support rods 51 cannot match the distance between the two connecting rods 2 before connecting the support rods 51 to the connecting rods 2, a base plate can be installed on the upper end of the connecting rods 2, and then the two support rods 51 can be installed on the base plate. If the dimensions between the two support rods 51 match the distance between the two connecting rods 2, the two support rods 51 can be installed on the two connecting rods 2 respectively by bolts.

[0041] In the above process, after the transformer is installed on the support plate 4, the electric telescopic cylinder 551 is activated, causing its output end to retract. This retraction drives the connected opening plate 553 downwards. At this time, the roller 552 connected to the moving opening plate 553 rubs against the belt 554, causing both rollers to rotate. The rear roller 552, through the electric telescopic cylinder 551, generates a reaction force on the belt 554, which in turn pulls the support plate 4 upwards via the triangular plate 56. This causes the support plate 4 to move the transformer upwards, moving it to the desired height. Then, the electric telescopic cylinder 551 is stopped, maintaining the distance the support plate 4 has traveled, thus moving the transformer to the desired position. This eliminates the need for complex installation methods, thereby improving work efficiency.

[0042] As described above, when the support plate 4 moves, it will cause the slider 53 to slide on the outer surface of the guide rod 54, thereby improving the stability of the support plate 4 during movement.

[0043] It should be noted that the specific installation method, circuit connection method and control method of the electric telescopic cylinder 551 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
