[0033] Next, the technical solution of the present invention will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0034] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other. The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0035] Please refer to Figure 1 and Figure 2 , a specific embodiment of the present utility model provides a bogie frame structure to solve the problem of low load-bearing capacity.

[0036] The bogie frame mounting structure includes: a bogie frame main body 1, a wheel set 2, a torsion arm 3, a speed reducer 4, a support assembly 5, and a wheel mounting seat 6.

[0037] Among them, the wheel sets 2 are longitudinally arranged below the bogie frame main body 1, and the wheel sets 2 are installed at intervals; a support assembly 5 is provided at the top of the three-wheel bogie frame 12 for supporting the entire rectifier trolley, and one end of the top of the two-wheel bogie frame 11 is connected to the torsion arm 3, and the other end of the torsion arm 3 is connected to the speed reducer 4.

[0038] The load-bearing capacity of the bogie frame is improved through the design of three wheels, and the load capacity is increased.

[0039] The bogie frame main body 1 includes: a two-wheel bogie frame 11 and a three-wheel bogie frame 12 that are hinged to each other; through the hinge connection between the two-wheel bogie frame 11 and the three-wheel bogie frame 12, the wheel sets 2 can all be at the same height and in contact with the ground.

[0040] The wheel set 2 has a driving wheel set 21, a first driven wheel set 22, and a second driven wheel set 23; the driving wheel set 21 and the first driven wheel set 22 are respectively installed on both sides of the two-wheel bogie frame 11, and the second driven wheel is installed at the end of the three-wheel bogie frame 12, so that the three wheels are spaced apart to share the required load.

[0041] By pivotally connecting the two-wheel bogie frame 11 and the three-wheel bogie frame 12, the three-wheel bogie frame 12 can pivot relative to the two-wheel bogie frame 11 to adjust the position of the three-wheel bogie frame 12. In this way, one of the wheel sets 2 installed on the three-wheel bogie frame 12 can be adjusted to the same height as the other two of the wheel sets 2. That is, the three wheel sets 2 in the mounting structure of the bogie frame can all be in contact with the ground, increasing the load capacity of the bogie frame. The situation where one of the wheel sets 2 is spaced from the ground due to assembly problems and cannot provide load is avoided.

[0042] Exemplarily, due to assembly and tolerance issues, the second driven wheel set 22 may not be in contact with the ground during use. By pivoting the three-wheel frame 12 counterclockwise relative to the two-wheel frame 11, the height of the second driven wheel set 22 is reduced until it contacts the ground, enabling the second driven wheel set 22 to support the frame body 1.

[0043] Please refer to Figure 2 and Figure 3 , the two-wheel frame 11 has a two-wheel frame body 111 and a pivot shaft 112;

[0044] An installation hole is provided in the middle of the two-wheel frame body 111, and an installation hole is also provided on the side of the starting end of the three-wheel frame 12. The pivot shaft 112 passes through both the two-wheel frame 11 and the three-wheel frame 12 at the same time.

[0045] In this embodiment, the two-wheel frame 11 and the three-wheel frame 12 are connected by inserting the pivot shaft 112, and the hinged connection of the frame body 1 is realized through the insertion connection method, with a simple structure and low processing difficulty.

[0046] Please refer to Figure 1 , the two-wheel frame is vertically arranged with the torsion arm, the end of the torsion arm 3 is connected to the speed reducer 4, and the speed reducer 4 is arranged parallel to the two-wheel frame 11.

[0047] The driving wheel shaft 211 is connected to the output shaft of the speed reducer 4.

[0048] Please refer to Figure 4 , the support assembly 5 has a support assembly body 51, a support assembly mounting seat 52, a support assembly end cover 53 and a rotating shaft 54;

[0049] Both the support assembly body 51 and the support assembly mounting seat 52 are provided with installation holes. The rotating shaft 54 is arranged inside the installation hole of the support assembly mounting seat 52 and is hinged to the support assembly body 51. The support assembly end cover 53 closes the installation holes from both ends of the support assembly body 51.

[0050] By separately providing the support assembly 5 for supporting the rectifier trolley, the support assembly 5 can swing slightly to further adjust the height of the second driven wheel set 22.

[0051] Please refer to Figure 2 、 Figure 3 , the driving wheel set 21 includes: a driving wheel shaft 211 and driving wheel wheels 212; the wheel mounting seat 6 includes: a driving wheel mounting seat 61, a first driven wheel mounting seat 62 and a second driven wheel mounting seat 63.

[0052] The driving wheel set 21 and the first driven wheel set 22 are respectively installed on both sides of the two-wheel frame 11. The driving wheel mounting seat 61 and the first driven wheel mounting seat 62 respectively fit with the two ends of the two-wheel frame 11. The driving wheel shaft 211 extends outward, and the second driven wheel set 23 is installed at the end of the three-wheel frame 12.

[0053] Please refer to Figure 3 and Figure 5 , the distance from one end of the two-wheel frame 11 to the pivot 112 is L1, and the distance from one end of the three-wheel frame 12 to the pivot 112 is L2, where L1:L2 = 1:(1.2 - 3);

[0054] In one embodiment, L1:L2 = 1:2; in another embodiment, L1:L2 = 1:2.5. The distance between the two-wheel frame 11 and the three-wheel frame 12 is determined according to the distribution of the load required in actual situations.

[0055] In this way, based on the lever theory, the distance of the two-wheel frame 11 is configured to be slightly longer than that of the three-wheel frame 12, so that the load on the two-wheel frame 11 is smaller and the load on the three-wheel frame 12 is larger, in order to adapt to the usage scenario where the load is more biased towards the three-wheel frame 12.

[0056] In the prior art, the fixing method of the frame and the wheel set is mostly that two connecting rods are distributed on both sides of the wheels. This connection method cannot withstand high-intensity operation and has weak bearing capacity, thus easily causing the connecting rods to break.

[0057] Please refer to Figure 1 and Figure 6 , the three-wheel frame 12 includes: a three-wheel frame main body 121 and a wheel mounting assembly 122. The part where the end of the three-wheel frame 12 extends is the wheel mounting assembly 122;

[0058] The wheel mounting assembly 122 includes: a bending plate 1221, an inner side plate 1222 and an end sealing plate 1223;

[0059] The bending plate 1221 has a structure of being folded in half on both sides, is internally attached to the three-wheel frame main body 121, and the bending direction is the same as the position where the second driven wheel set 23 is located. The side of the inner side plate 1222 is connected to the bending plate 1221. The bottom end of the inner side plate 1222 is connected to the second driven wheel mounting seat 63. The end sealing plate 1223 is installed at the top end of the inner side plate 1222 and extends obliquely downward. The inner side plate 1222 and the bending plate 1221 are both arranged at intervals;

[0060] The inner side plate 1222 is adopted in the wheel mounting assembly 122. On the one hand, the inner side plate 1222 can enhance the bearing capacity of the wheel set 2 and increase the load capacity. On the other hand, it enhances the ability of the second driven wheel set 23 to resist external interference, thereby avoiding the swing of the wheel set 2 during the movement process and enhancing the stability of the wheel set 2;

[0061] In addition, the specific shapes, bending angles, and bending times of the inner side plate 1222 and the bending plate 1221 can all be adjusted. For example, the bending plate 1221 is bent three times.

[0062] Obviously, the above embodiments are merely examples for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or alterations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or alterations derived therefrom still belong to the creation of the present utility model.
