[0002] Once an emergency occurs in the generator circuit breaker (GCB) used in large-scale generator sets in service in China, the original spare parts and technical support cannot be obtained in time due to the long distance to the factory. Therefore, the unit will be shut down, and the safety of electricity use cannot be guaranteed. At the same time, it will also need to be shut down for a certain period of time, resulting in downtime losses. Therefore, it is proposed to use a temporary replacement device for generator circuit breaker failure to solve the above technical problems. However, since the external dimensions of the temporary replacement device are smaller than the external dimensions of the original generator circuit breaker, it is necessary to adjust the installation height and installation level of the temporary replacement device to meet the requirements of docking and installation with the busbar terminals at both ends of the generator circuit breaker (the busbar terminal is a fixed terminal used to connect to the generator circuit breaker). For this purpose, an adjustment support device is designed. Utility Model Content

[0021] See also Figure 1-3An adjustable support device for a fault replacement device of a generator circuit breaker includes a steel frame and a support platform 30, the support platform 30 is installed on the steel frame through an adjustment device 20; the steel frame includes at least two brackets 10, the bracket 10 includes a bottom beam 11, a longitudinal beam 12 and a cross beam 13, at least two longitudinal beams 12 are installed on the bottom beam 11, a cross beam 13 is installed on the top of the longitudinal beam 12, the cross beam 13 is connected to the support platform 30 through the adjustment device 20, the support platform 30 is suspended between the two longitudinal beams 12, and the height and horizontal state of the support platform 30 can be adjusted through the adjustment device 20. The height and horizontal state of the support platform 30 can be conveniently adjusted through the adjustment device 20, thereby meeting the installation requirements of the temporary replacement device.

[0022] Preferably, the support platform 30 is a steel structure frame.

[0023] Preferably, the bottom beam 11 and the longitudinal beam 12 are made of I-beams or channel steels, and the cross beam 13 is made of rectangular steel pipes.

[0024] When in use, the temporary replacement device 50 is mounted on the support platform 30 by bolts.

[0025] See also Figure 1-3 Four longitudinal beams 12 are installed on the bottom beam 11, three supporting platforms 30 are respectively located between adjacent longitudinal beams 12, and the cross beam 13 is connected to the supporting platform 30 through the adjusting device 20 on the side close to the supporting platform 30. Thus, the installation of three temporary replacement devices 50 can be satisfied at the same time.

[0026] Two or three brackets 10 are provided. Preferably, two brackets 10 are provided.

[0027] In a preferred embodiment, see Figure 1 , 2 The adjusting device 20 includes a first screw rod 21, the upper end of which is connected to the cross beam 13, and the lower end of which movably passes through the support platform 30. The first screw rod 21 is respectively screwed with first nuts 22 on the upper and lower sides of the support platform 30, and the support platform 30 is suspended below the cross beam 13 through the first screw rod 21. By adjusting the positions of the first nuts 22 on the upper and lower sides of the support platform 30, the height and horizontal state of the support platform 30 can be adjusted. In this solution, the upper end of the first screw rod 21 needs to be connected and fixed to the cross beam 13, for example, by welding.

[0028] Furthermore, in order to facilitate the connection between the first screw rod 21 and the cross beam 13 at the installation site, the upper end of the first screw rod 21 passes through the cross beam 13 , and the first screw rod 21 is also screwed with first nuts 22 on the upper and lower sides of the cross beam 13 .

[0029] Furthermore, since the support platform 30 is suspended and installed by four first screw rods 21, when the temporary replacement device 50 is installed on the support platform 30, it is easy to cause the support platform 30 to shake, causing the first screw rods 21 to deform. Therefore, a limit tube 23 is installed on the bottom beam 11, and the lower end of the first screw rod 21 located at the support platform 30 extends into the limit tube 23. The lower end of the first screw rod 21 is positioned by the limit tube 23. When adjusting, the height and horizontal state of the support platform 30 can be adjusted by adjusting the positions of the first nuts 22 on the upper and lower sides of the support platform 30.

[0030] See also Figure 1 , 2 The two outermost cross beams 13 on the bracket 10 are fixedly connected to the bottom beam 11 at one end away from the support platform 30 through the connecting piece 14. Since the adjustment device 20 is installed at one end of the two outer cross beams 13 and the support platform 30 is suspended, the cross beams 13 have a tendency to tilt inwards. In order to ensure the stability of the two outer cross beams 13 and the longitudinal beams 12, the two outer cross beams 13 are fixedly connected to the bottom beam 11 at one end away from the support platform 30 through the connecting piece 14, thereby enhancing the structural strength of the two outer cross beams 13 and the longitudinal beams 12.

[0031] See also Figure 3 , each of the brackets 10 is connected to form a whole by a connecting beam 40, and the steel frame structure is stable and well-shaped. When the connecting beam 40 is not provided, the bracket 10 is small in size, which is convenient for later disassembly and transportation. During installation, the bracket 10 can be welded to the embedded bottom plate of the ground foundation. Or a hole is opened on the bottom beam 11 to be installed and connected with the original anchor bolts.

[0032] The working process or principle of the utility model is as follows:

[0033] When in use, the two brackets 10 are installed and connected with the original anchor bolts through the openings on the bottom beam 11.

[0034] The support platform 30 is placed on the limiting tube 23 between the two longitudinal beams 12, and the first screw 21 is inserted into the support platform 30 from above the cross beam 13. After the first screw 21 passes through the cross beam 13, at least two first nuts 22 are screwed on the first screw 21, and then the support platform 30 is lifted. At this time, it is necessary to ensure that the nut on the first screw 21 does not interfere with the cross beam 13, and two first nuts 22 are installed on the lower side of the first screw 21 located on the support platform 30, and ensure that the lower end of the first screw 21 can extend into the limiting tube 23.

[0035] Afterwards, two first nuts 22 are screwed onto the first screw rod 21 above the cross beam 13 , and the positions of the first nuts 22 on the upper and lower sides of the cross beam 13 are adjusted, and the first screw rod 21 is fixed to the cross beam 13 .

[0036] See also Figure 1, 3 By adjusting the positions of the first nuts 22 on the upper and lower sides of the four corners of the support platform 30, the height and horizontal state of the support platform 30 can be adjusted.
