[0036] In order to enable people skilled in the art to better understand the solution of the present application, the technical solution in the embodiment of the present application will be clearly and completely described below in conjunction with the drawings in the embodiment of the present application.

[0037] like Figures 1 to 3 As shown, a generator set frame structure includes a frame base 1 and a universal wheel provided at the bottom of the frame base 1. The generator set frame structure also includes:

[0038] A plurality of fixing parts 2 are provided on the frame base 1, and the fixing parts 2 are used to support the frame base 1 to a certain height so that the universal wheels are off the ground.

[0039] The fixing part 2 includes:

[0040] A guide block 21 is fixed to the bottom of the frame base 1 .

[0041] The support leg 27 is slidably mounted on the outside of the guide block 21 .

[0042] The adjusting screw 23 provided in the supporting leg 27 is rotated, and one end of the adjusting screw 23 is threadedly connected to the threaded hole 22 provided at the bottom of the guide block 21. The adjusting screw 23 is used to adjust the height of the rack base 1 from the ground.

[0043] The adjusting gear 24 provided on the frame base 1 is rotated.

[0044] The spline rod 26 is inserted and connected with the spline groove 25 provided on the adjusting tooth 24. The bottom end of the spline rod 26 is fixed to the top end of the adjusting screw 23. The top of one of the spline rods 26 is provided with a crank.

[0045] The generator set frame structure also includes a transmission chain 3 for linking all the regulating teeth 24 to rotate synchronously in the same direction.

[0046] In the initial state, the support leg 27 is sleeved on the guide block 21, and the support leg 27 is off the ground. At this time, the user can easily push the frame base 1 to the specified position through the universal wheel provided at the bottom thereof, and then hold the crank and shake it clockwise, so that it will drive the spline rod 26 and the adjusting screw 23 to rotate synchronously in the same direction. Due to the coordinated use of the spline rod 26 and the spline groove 25 on the adjusting tooth 24, the adjusting tooth 24 is driven to rotate synchronously in the same direction. Through the power transmission of the transmission chain 3, the remaining adjusting teeth 24 are driven to rotate synchronously in the same direction, and the rotating adjusting screw 23 will The screw 23 is rotated to adjust the support leg 27 downward until the bottom of the support leg 27 contacts the ground. At this time, the crank handle is continuously shaken to cause a vertical relative displacement between the guide block 21 and the support leg 27, that is, the guide block 21 and the rack base 1 are lifted up until the universal wheel is off the ground, and the lifting and lowering adjustment of the rack base 1 is completed, so that the lifting and lowering adjustment process remains stable, and no multiple people are required to cooperate in the operation. Only one person is needed to complete the lifting and lowering operation of the rack base 1, saving labor costs.

[0047] In this embodiment, the guide blocks 21 are located at the corners of the bottom of the rack base 1, and the universal wheels are located in the support area surrounded by all the guide blocks 21. Such a design can effectively avoid the problem of mutual interference between the universal wheels and the support legs 27, so that the two can move independently without affecting the stability of the rack base 1, so that the user can push the rack base 1 to move and change positions, or fix it at a specified position.

[0048] In this embodiment, the fixing portion 2 further includes:

[0049] A receiving groove 28 is provided on the top of the supporting leg 27 , and the bottom of the guide block 21 is slidably sleeved in the receiving groove 28 .

[0050] The protrusion fixed on the inner wall of the receiving groove 28 is slidably connected to the limiting groove 29 provided on the outside of the guide block 21.

[0051] This design is used to improve the connection stability between the support leg 27 and the guide block 21 , and to prevent the support leg 27 and the guide block 21 from being separated and affecting the stability of the rack base 1 .

[0052] In this embodiment, the spline groove 25 is coaxial with the threaded hole 22, and the spline groove 25 is coaxial with the adjusting tooth 24. This design allows all the adjusting screws 23 to be driven synchronously and in the same direction by shaking the crank handle and cooperating with the power transmission effect among the transmission chain 3, the adjusting tooth 24, and the spline rod 26, so that all the supporting legs 27 can synchronously lift the frame base 1 to a certain height smoothly and steadily. The entire operation process can be completed by only one person, saving labor costs.

[0053] In this embodiment, the generator set frame structure further includes a protective frame 5 provided on the top of the frame base 1 , and a frame lifting portion 4 for adjusting the height of the protective frame 5 is provided between the protective frame 5 and the frame base 1 .

[0054] In this embodiment, the frame lifting unit 4 includes:

[0055] The sleeve leg 46 is slidably sleeved on the outer side of the upper leg of the protection frame 5, and the sleeve leg 46 is fixed on the top of the frame base 1.

[0056] An elastic plug 41 is provided on the sleeve leg 46, and the elastic plug 41 includes a spring fixed to the outside of the sleeve leg 46, and a plug rod is provided inside the spring, one end of the plug rod is fixedly connected to one end of the spring, and the other end of the spring is fixed to the outside of the sleeve leg 46, and the plug rod is perpendicular to the sleeve leg 46, and one end of the elastic plug 41 is plugged into a through hole provided on the sleeve leg 46 and the outside of the support leg on the protective frame 5.

[0057] With such a design, the user only needs to remove and plug in the protective frame 5 to release the fixed relationship between the leg sleeve 46 and the protective frame 5, or to fix the leg sleeve 46 and the protective frame 5 together. By adjusting the perforations of different heights on the protective frame 5 to align with the perforations on the leg sleeve 46, and passing the insertion rod horizontally through the corresponding perforations on the protective frame 5 and the leg sleeve 46, the height of the protective frame 5 can be adjusted to facilitate the protection of generator sets at different heights.

[0058] In this embodiment, the frame lifting unit 4 further includes:

[0059] A slider 45 is slidably connected to a slide groove 44 provided on the top of the protective frame 5 .

[0060] A moving block 47 is slidably connected to a guide groove provided on the top of the frame base 1 .

[0061] Two supporting booms 42 are relatively fixed on the protection frame 5 .

[0062] Two oblique support rods 43 are cross-hinged at the bottom end of the support boom 42 , and both ends of the oblique support rod 43 are hinged on the slider 45 and the moving block 47 respectively.

[0063] With such a design, during the height adjustment process of the protective frame 5, the vertical angle between the two cross-arranged diagonal support rods 43 can be reduced, so that the height of the support surfaces of the two becomes larger, and conversely the width of the support surfaces of the two becomes smaller. This allows the height of the protective frame 5 to be adjusted without affecting the overall support strength of the protective frame 5, so that the protective frame 5 can provide external protection for generator sets of different heights.

[0064] Working principle: In the initial state, the support leg 27 is sleeved on the guide block 21, and the support leg 27 is off the ground. At this time, the user can easily push the frame base 1 to the specified position through the universal wheel provided at the bottom thereof, and then hold the crank and shake it clockwise, so that it will drive the spline rod 26 and the adjusting screw 23 to rotate synchronously in the same direction. Due to the coordinated use of the spline rod 26 and the spline groove 25 on the adjusting tooth 24, the adjusting tooth 24 is driven to rotate synchronously in the same direction. Through the power transmission of the transmission chain 3, the remaining adjusting teeth 24 are driven to rotate synchronously in the same direction. The rotating adjusting screw 23 will cause a relative linear displacement between the threaded hole 22 in the vertical direction. The rotating adjusting screw 23 pushes the support leg 27 downward until the bottom of the support leg 27 contacts the ground. At this time, continuing to shake the crank can make the guide block 21 When the vertical relative displacement occurs between the support legs 27, the guide block 21 and the frame base 1 are lifted until the universal wheel is off the ground, and the lifting adjustment of the frame base 1 can be completed, so that the lifting adjustment process remains stable and only one person is required to operate it, saving labor costs. When installing the generator set on the frame base 1, the user can release the fixed relationship between the leg 46 and the protective frame 5 by pulling out the plug rod according to the height of the generator set, and then adjust the perforations of different heights on the protective frame 5 to align with the perforations on the leg 46. After adjusting the height of the protective frame 5, the plug rod is passed horizontally through the corresponding perforations on the protective frame 5 and the leg 46 to achieve a fixed connection between the leg 46 and the protective frame 5, and the height adjustment of the protective frame 5 can be completed, so as to protect generator sets of different heights. The operation is simple and efficient.
