Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Figure 1 The front view of the loading tool in the utility model is shown. Figure 2 The top view of the loading tool in the utility model is shown. Figure 3 The side view of the loading tool in the utility model is shown, and the loading tool comprises: a loading tool body 1 and one or more reinforcing ribs 2. In this embodiment, the one or more reinforcing ribs 2 are six reinforcing ribs 2, wherein the six reinforcing ribs 2 are divided into three groups of reinforcing ribs 2, each group of reinforcing ribs 2 is symmetrically distributed on the loading tool body 1, and each of the reinforcing ribs 2 is welded on the loading tool body 1, so that the reinforcing ribs 2 and the loading tool body form a whole, ensuring that the contact area formed between the reinforcing ribs 2 and the loading tool body 1 is large, so that the reinforcing ribs 2 have better firmness and anti-seismic ability. The reinforcing ribs 2 are used to strengthen the strength and rigidity of the loading tool body 1, avoid the risk of distortion and deformation of the loading tool during loading, and increase the service life of the loading tool body 1.

[0027] The loading tool body 1 includes: an upper bearing seat 11 and a lower loading seat 11, wherein the upper bearing seat 11 is fixedly connected to the lower loading seat 11 based on a connecting column 13, wherein the top of the connecting column 13 is connected to the upper bearing seat 11, and the bottom of the connecting column 13 is connected to the lower loading seat 11; and a connecting pin 14 is provided above the upper bearing seat 11, wherein the connecting pin 14 is used to connect the loading tool to the carriage of a tram. A plurality of process holes 121 are provided on the lower loading seat 11, and the plurality of process holes 121 are symmetrically distributed on the lower loading seat 11. The upper bearing seat 11 is used to receive the pressure of the hydraulic cylinder and transmit the pressure of the hydraulic cylinder to the lower loading seat 11, and the lower loading seat 11 is used to load the secondary spring of the bogie. In this embodiment, four process holes 121 are provided on the lower loading seat 11, and the four process holes 121 are symmetrically distributed on the lower loading seat 11, that is, two process holes 121 are distributed on one side of the lower loading seat 11, and two process holes 121 are distributed on the other side of the lower loading seat 11. The process holes 121 reduce the weight of the lower loading seat 11, making manual handling or installation easier, and the process holes 121 provide multiple fulcrums, which are convenient for manual handling of the loading tooling and for using transportation tools to carry the loading tooling.

[0028] Furthermore, any of the reinforcing ribs 2 is triangular, and the reinforcing ribs 2 include: a first reinforcing rib 21 and a second reinforcing rib 22; the length of the bottom side of the first reinforcing rib 21 is A1, the length of the bottom side of the second reinforcing rib 22 is A2, and the constraint relationship between A1 and A2 is A1>A2. Since the lower loading seat 11 is elliptical, the first reinforcing rib 21 is located on the longer directrix of the lower loading seat 11, and the second reinforcing ribs 22 are symmetrically distributed on the lower loading seat 11 with the first reinforcing rib 21 as the axis of symmetry, and the four second reinforcing ribs 22 are distributed in a cross shape. And the bottom side of any of the reinforcing ribs 2 extends from the connecting column 13 to the edge of the lower loading seat 11, which is conducive to the reinforcing rib 2 to evenly transfer the pressure it bears to the lower loading seat 11.

[0029] It should be noted that the four second reinforcing ribs 22 are distributed in a cross shape to achieve mutual support and reinforcement in two directions, thereby improving the stability of the second reinforcing ribs 22 on the connecting column 13 and improving the bearing capacity of the connecting column 13 .

[0030] Furthermore, any of the reinforcing ribs 2 is a triangle, the root of any of the reinforcing ribs 2 is connected to the lower loading seat 11, and the side of any of the reinforcing ribs 2 is connected to the connecting column 13. The triangle is the most stable shape, and the triangle can effectively distribute the load to other places, making the overall structure more stable. Secondly, the interior of the triangle can reduce fluidity, avoid shaking of the internal structure of the loading tool, effectively prevent external forces from eroding the internal structure, and increase the resistance of the loading tool to external forces.

[0031] Furthermore, the lower loading seat 11 is provided with a connection hole 122, and a positioning pin 123 is inserted into the connection hole 122; the connection holes 122 are distributed at the bottom of the lower loading seat 11 according to preset positions. In this embodiment, two positioning pins 123 are provided on the bottom of the lower loading seat 11, and one positioning pin 123 of the two positioning pins 123 is correspondingly arranged below one of the two first reinforcing ribs 21. The positioning pin 123 is used to connect the secondary spring to increase the stability of the lower loading seat 11 and the secondary spring during the loading process. The positioning pin 123 is inserted into the positioning hole specified by the spring adjusting device to avoid the lower loading seat 11 from being offset due to shaking during the loading process, which is beneficial to improving the reliability of the loading tooling.

[0032] Furthermore, a connecting portion 15 is provided at the top of the connecting pin 14, and a snap-in hole 151 is provided on the connecting portion 15. The connecting portion 15 is used to connect the loading device, and the snap-in hole 151 is used to be installed at a specified position of the loading device, so that the positioning portion of the loading device is inserted into the snap-in hole 151 to temporarily fix the position of the connecting pin 14. When the connecting pin 14 is inserted into the corresponding position of the loading device, the positioning portion of the loading device is inserted into the snap-in hole 151, and the positioning portion abuts against the inner wall of the snap-in hole 151, thereby limiting the rotation of the connecting pin 14, avoiding a small deviation of the connecting pin 14 after being vibrated during use, and improving the stability of the connecting pin 14 during use.

[0033] Furthermore, the diameter of the bottom of the connecting portion 15 is D1, the diameter of the top of the connecting portion 15 is D2, and the diameter of the connecting pin 14 is D3, and the constraint relationship between D1, D2 and D3 is: D1<D2≤D3. And the bottom of the connecting portion 15 is connected to the top of the connecting pin 14, then a slot is formed at the bottom of the connecting portion 15, and this slot can be used to clamp the connecting pin 14 at a specified position of the loading device, and the top of the connecting pin 14 is in contact with the loading device. When the loading device applies pressure to the connecting pin 14, the friction between the loading device and the connecting pin 14 can be increased, so as to avoid a small deviation of the connecting pin 14 after being vibrated during use, thereby improving the stability of the connecting pin 14 during use.

[0034] Furthermore, an anti-rust oil coating is provided on the surface of the connecting pin 14. The anti-rust oil coating can prevent the surface of the connecting pin 14 from being oxidized, protect the connecting pin 14 from corrosion factors such as high humidity and acidic environment, and effectively extend the service life of the connecting pin 14. Secondly, the anti-rust oil coating can not only play an anti-corrosion role, but also play a lubricating role, reducing the friction between the connecting pin 14 and the loading device, thereby reducing energy loss and reducing the wear of the connecting pin 14, which is conducive to improving the working efficiency of the loading device and extending the service life of the connecting pin 14.

[0035] Furthermore, the surface of the loading tool body 1 is provided with an anti-rust coating. The anti-rust coating can prevent the surface of the loading tool from contacting with the corrosive medium, thereby slowing down the oxidation process of the loading tool. Secondly, the anti-rust coating can also protect the appearance of the loading tool. The anti-rust coating acts as a protective layer to prevent the loading tool from being worn after being hit, which is conducive to extending the service life of the loading tool.

[0036] Furthermore, the material of the loading tool body 1 is carbon structural steel. In the present embodiment, the material of the loading tool is Q235. Q235 steel has excellent mechanical properties and strong bearing capacity, which is beneficial to the loading tool body 1 under high impact load. The loading tool can absorb more energy and maintain its shape, that is, it can maintain good shape and dimensional stability when impacted during use, reducing the risk of plastic deformation. Secondly, Q235 steel has good wear resistance. In a high-impact environment, the surface of the material is susceptible to wear, while Q235 steel has good hardness and wear resistance, and can resist wear, thereby maintaining the good condition of the loading tool.

[0037] The utility model also proposes a weighing spring-adjusting device, which includes a plurality of the above-mentioned loading fixtures and a weighing spring-adjusting mechanism, wherein the loading fixture is located above the weighing spring-adjusting mechanism. In this embodiment, two loading fixtures are provided on the weighing spring-adjusting device to ensure that the weighing spring-adjusting device is adapted to the position of the second spring of the tram bogie. The two loading fixture bodies 1 are respectively installed on the weighing spring device, which not only satisfies the simultaneous loading of both sides of the bogie, but also realizes single-side loading, meeting the loading requirements of the tram.

[0038] To sum up, the utility model provides multiple reinforcing ribs, and some of the reinforcing ribs are distributed in a cross shape on the loading tooling, which can achieve mutual support and reinforcement in two directions, thereby improving the stability of the reinforcing ribs on the loading tooling and improving the load-bearing capacity of the loading tooling; secondly, by providing multiple process holes on the lower loading seat, the process holes reduce the weight of the lower loading seat, making manual handling or installation easier, and the process holes provide multiple fulcrums, which is convenient for manual handling of the loading tooling and the use of transportation tools to carry the loading tooling.
