[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0023] A semitrailer axle fixing device provided by some embodiments of the utility model will be described below in conjunction with the accompanying drawings.

[0024] Embodiment 1:

[0025] Combination Figure 1-2As shown, the utility model provides a semi-trailer axle fixing device, comprising: a trailer lifting eye 100, a replacement component 200, and a reinforcement component 300; the replacement component 200 comprises a lifting eye pin hole component 201 movably installed at the lower end of the trailer lifting eye 100, a support frame 202 welded and fixed on both sides of the lower end of the trailer lifting eye 100, and insertion holes 203 and mounting holes 204 respectively opened on both sides of the lifting eye pin hole component 201 and corresponding to the two sides of the trailer lifting eye 100; locking bolts 205 are also movably installed in the insertion holes 203 and the mounting holes 204, and the lifting eye pin hole component 201 is a T-shaped structure as a whole.

[0026] Specifically, the semi-trailer axle fixing device refers to the trailer lifting eye 100, which is welded to the upper end of the beam at the bottom of the semi-trailer when in use. It is a component for installing and fixing the semi-trailer axle, which can ensure the structural stability of the semi-trailer axle after installation and the safety during use; the lifting eye pin hole component 201, which is flexibly installed on the semi-trailer axle at the lower end of the trailer lifting eye 100, can be conveniently disassembled through the trailer lifting eye 100 after being worn out during use or after the pin hole inside it is damaged, so as to replace a new lifting eye pin hole component 201, thereby connecting and installing the semi-trailer axle, and after the lifting eye pin hole component 201 is installed, the support frames 202 on both sides of the bottom and the locking bolts 205 installed between the lifting eye pin hole component 201 and the trailer lifting eye 100 can also ensure the installation strength and stability of the lifting eye pin hole component 201.

[0027] Embodiment 2:

[0028] Combination Figure 2-3 As shown, on the basis of Example 1, the reinforcement assembly 300 includes a welded top plate 301 fixedly installed on the top of the trailer lifting eye 100, a fixed frame 302 welded and fixed on the outside of the trailer lifting eye 100, a pressure plate 303 movably installed in the fixed frame 302, and a reinforcement plate 304 welded and fixed on the inside of the trailer lifting eye 100, and reinforcing ribs 305 are welded on both sides of the reinforcement plate 304. A plurality of groups of internal welding holes 306 are arranged in the welded top plate 301, and the internal welding holes 306 are all conical structures.

[0029] Specifically, the welded top plate 301 on the top of the trailer lifting eye 100 and the pressure plates 303 and reinforcement plates 304 that are welded and fixed on both sides after installation can ensure the welding strength when the trailer lifting eye 100 is welded to the bottom beam of the semi-trailer, thereby ensuring the stability of the trailer lifting eye 100 after welding. The pressure plate 303 in the fixing frame 302 is mainly used for welding to the outer end of the fixing frame 302 when the upper part is engaged with the upper end of the beam, thereby strengthening the outer end strength of the trailer lifting eye 100 after installation. The inner end of the trailer lifting eye 100 is welded and fixed. The reinforcing plate 304 and the reinforcing rib 305 at the upper end of the reinforcing plate 304 are mainly used to ensure the strength of the inner end of the trailer lifting eye 100 after installation. The inner welding holes 306 of the conical structure arranged in the welding top plate 301 are mainly used to weld the top plate 301 to the beam after welding, and then weld it to the beam through the inner welding holes 306, so that the inner and outer ends of the welding top plate 301 are welded at the same time, ensuring the welding strength between the top of the trailer lifting eye 100 and the beam, so as to jointly ensure the stability of the trailer lifting eye 100 after installation.

[0030] The working principle and use process of this utility model:

[0031] After the eyelet pin hole 201 at the lower part of the trailer eye 100 is damaged, the semi-trailer axle installed and connected in the eyelet pin hole 201 is first disassembled. After the semi-trailer axle is removed, the locking bolt 205 inside the upper end plug hole 203 and the mounting hole 204 of the eyelet pin hole 201 is removed. After the locking bolt 205 is removed, the eyelet pin hole 201 is moved up and removed. After the new eyelet pin hole 201 is re-fixed and installed, the semi-trailer axle can be installed and connected again. At the same time, the inner welding hole 306 and the welded top plate 301 welded inside and outside the top of the trailer eye 100, the pressure plate 303 welded and engaged on the outside, and the reinforcing plate 304 welded and fixed on the inside can also ensure the welding strength of the trailer eye 100 on the bottom beam of the semi-trailer, thereby ensuring the stability of the semi-trailer axle in the trailer eye 100 after installation.
