[0018] Fig. 2 is a side view schematic view of the clamping device. DETAILED DESCRIPTION

[0019] In order to better understand the purpose, structure and function of the utility model, the following will be combined with the accompanying drawings to describe the utility model in detail. Figs. 1-2 The height-adjustable fixing device is further described in detail.

[0020] As Fig. 1 and Fig. 2As shown, the height-adjustable fixing device of the embodiment of the utility model includes upper support assembly 10, side support assembly and lower support assembly. The lower support assembly is segmented structure, and the lower support assembly includes two sections, one section is first lower support part 31, and the other section is second lower support part 33. Second lower support part 33 is hollow tubular structure, and the outer diameter of first lower support part 31 is less than the inner diameter of second lower support part 33, so that first lower support part 31 is arranged in the interior of second lower support part 33, and in use, the length of the whole lower support assembly can be changed by the telescoping of first lower support part 31 in the interior of second lower support part 33. One end of second lower support part 33 connected with first lower support part 31 is provided with clamping device 35, and after the threaded bolt of clamping device 35 is arranged, second lower support part 33 is clamped and fixed, and first lower support part 31 is rotatably connected with one end of upper support assembly 10 and side support assembly, and the other end of side support assembly is rotatably connected with lower support assembly. When the length of lower support assembly is adjusted to the appropriate length, first lower support part 31 and second lower support part 33 are fixed by clamping device 35, so that the relative position of the two remains unchanged. The upper support assembly 10 is provided with a clamping assembly 40, and the clamping assembly 40 is used for clamping the iron core.

[0021] In the utility model, when the transformer iron core 60 needs to be fixed, the transformer iron core 60 is first clamped and fixed by the upper clamping assembly 40 and the lower clamping assembly 50, and then a plurality of lower supporting foot assemblies 70 are fixed on the lower clamping assembly 50. And the lower supporting foot assembly 70 is in perpendicular relationship with the lower clamping assembly 50, and the lower supporting foot assembly 70 is in contact with the ground, and this design can also reduce the shaking degree of the transformer iron core 60 in the transportation process. The upper clamping assembly 40 is also provided with a plurality of lifting holes 41 for lifting and transporting the transformer iron core 60.

[0022] After the transformer iron core 60 is clamped and fixed, the height-adjustable fixing device needs to be fixed on the upper clamping assembly 40. In the fixing process, one upper support assembly 10 is first fixed on one side of the upper clamping assembly 40, and the upper support assembly 10 is in perpendicular relationship with the upper clamping assembly 40. Since the upper support assembly 10 is rotatably connected with the side support assembly, and the side support assembly is also rotatably connected with the lower support assembly.

[0023] It can be understood that the telescoping of the first lower support component 31 within the second lower support component 33 can change the length of the lower support assembly, and since the lower support assembly is rotationally connected with the side support assembly, the longer the lower support assembly, the shorter the distance between the upper support assembly 10 and the lower support assembly, i.e. the lower support assembly is farther away from the ground. Assuming that the first side support component 21 is regarded as the hypotenuse a side of a right triangle, the first lower support component 21 and the second lower support component 33 are regarded as a right angle b side of the right triangle, and the distance between the upper support assembly 10 and the lower support assembly is regarded as the other right angle c side of the right triangle, when the length of the a side is constant, the longer the b side, the shorter the c side, and vice versa. After the upper support assembly 10 is fixedly connected with the upper clamping assembly 40, the first lower support component 31 is inserted into the second lower support component 33, and the distance between the lower support assembly and the ground is shortened by continuously inserting, and in the process of the lower support assembly approaching the ground, the lower support assembly and the side support assembly are rotated, wherein the angle between the first side support component 21 and the first lower support component 31 becomes larger and larger, and the angle between the second side support component 22 and the second angle fixing disc 34 also becomes larger and larger. Since the upper support assembly 10 and the side support assembly are rotationally connected, when the lower support assembly approaches the ground, the upper support assembly 10 and the side support assembly also continuously rotate. When the length of the hypotenuse is constant, the angle between the hypotenuse and the top of the trapezoid and the ground will change when the length of the bottom of the trapezoid changes, and the rotational connection between the upper support assembly 10 and the side support assembly and the rotational connection between the side support assembly and the lower support assembly enable the change of the angle to be realized.

[0024] When the lower support assembly is in close contact with the ground, the length of the lower support assembly can be adjusted by the clamping device 35. The clamping device 35 is provided with two parallel clamping plates 36, which are fixedly connected to the second lower support member 33 perpendicularly. The clamping plates 36 are provided with a plurality of pressing through holes 37 for bolts. The bolts pass through the pressing through holes 37 of one clamping plate 36 and pass out of the pressing through holes 37 of the other clamping plate 36. The axis direction of the bolts is perpendicular to the axis direction of the second lower support member 33. After the bolts are tightened in the pressing through holes 37, the first lower support member 31 can be pressed. In some embodiments, the second lower support member 33 has a gap between the two clamping plates 36, which can better clamp. The position between the first lower support member 31 and the second lower support member 33 is kept unchanged. In order to further fix the height-adjustable fixing device, the first angle fixing disc 32 is arranged on the first lower support member 31 at the end where the first lower support member 31 is rotationally connected to the first side support member 21. The second angle fixing disc 34 is arranged on the second lower support member 33 at the end where the second lower support member 33 is rotationally connected to the second side support member 22. Meanwhile, the end where the side support assembly is rotationally connected to the lower support assembly is provided with a threaded hole. After the length of the lower support assembly is fixed, the angle between the side support assembly and the lower support assembly is determined. At this time, the bolt is screwed into the threaded hole of the first side support member 21 through the arc-shaped slot on the first angle fixing disc 32. The bolt is screwed into the threaded hole of the second side support member 22 through the arc-shaped slot on the second angle fixing disc 34. After the bolt is tightened, the angle between the first side support member 21 and the first lower support member 31 is further fixed, and the angle between the second side support member 22 and the second lower support member 34 is further fixed, thereby improving the stability of the entire height-adjustable fixing device. Thus, the height-adjustable fixing device is fixed to the transformer core 60.

[0025] When the height-adjustable fixing device is fixed to the transformer core 60, the upper support assembly 10, the side support assembly, and the lower support assembly together form a trapezoid, which increases the contact area of the transformer core 60 with the ground and effectively suppresses the lateral inclination of the transformer core 60.

[0026] In an embodiment, one end of the upper support assembly 10 is detachably rotationally connected to the first side support member 21, and the other end of the upper support assembly 10 is detachably rotationally connected to the second side support member 22. This design can conveniently disassemble the upper support assembly 10 and the side support assembly, facilitate storage, or replace part of the assembly.

[0027] It should be explained finally: above described only is preferred embodiment of the utility model, and is not for limiting the protection scope of the utility model. Any modification, equivalent replacement, improvement etc. that is made within the spirit and principle of the utility model, should be contained in the protection scope of the utility model.
