[0021] like Figures 1 to 8 As shown, this utility model provides a bottom-opening open wagon chassis 1 with combined lifting lugs. The bottom-opening open wagon chassis 1 with combined lifting lugs includes: a chassis 1, lifting lug bodies 2, and stop bodies 3.

[0022] The underframe 1 is the underframe 1 of a bottom-opening open wagon for railway freight cars. Impact seats 4 are fixed to both ends of the end beams of the underframe 1, and the impact seats 4 are located at the outer ends of the side beams. Each impact seat 4 is equipped with a lifting slot and an anti-detachment slot. The two anti-detachment slots are located above the lifting slot and are symmetrical about the vertical center line of the lifting slot. Each lifting slot is equipped with a lifting lug body 2. The stop body 3 passes through the corresponding lifting lug body 2 and is inserted into the corresponding anti-detachment slot. The lifting lug body 2 includes a base plate 21, a stop 22, and a lifting ring 23. The base plate 21 is a plate as a whole, and includes a limiting stop 24. The limiting stop 24 is a plate adapted to the structure of the lifting groove. The limiting stop 24 is inserted into the lifting groove, and the upper end surface of the limiting stop 24 is in contact with the top surface of the lifting groove.

[0023] The stop 22 is a block structure. The two stops 22 are fixed on the bottom plates 21 on both sides of the limiting stop 24, and the side of the stop 22 is adapted to the outer side of the side beam. The stop 22 is provided with through holes 26. When the limiting stop 24 is inserted into the lifting groove, the through holes 26 of the two stops 22 correspond one-to-one with the two anti-detachment grooves. The stop body 3 passes through the through holes 26 and is inserted into the anti-detachment groove.

[0024] A lifting ring 23 is fixed on the bottom plate 21 on the outer side of each of the two stops 22.

[0025] Preferably, the stop body 3 is a block structure, the lower end face of the stop body 3 is horizontal, and the upper end face of the stop body 3 is inclined from the middle to the other end of the stop body 3.

[0026] Preferably, the through hole 26 of the stop 22 is adapted to the structure of the stop body 3, the bottom surface of the through hole 26 is a plane, and the top surface of the through hole 26 is an inclined surface adapted to the upper end surface of the stop body 3.

[0027] Preferably, protrusions are provided on the outer surfaces of the side beams on both sides of the anti-detachment groove.

[0028] The bottom plates 21 on both sides of the limiting stop 24 are provided with slots 25, and the two slots 25 are provided with two protrusions in a one-to-one correspondence. When the limiting stop 24 is inserted into the lifting groove, the protrusions are set in the slots 25.

[0029] Preferably, the upper surface of the base plate 21 is inclined downward from the side away from the base frame 1 to the limiting stop 24.

[0030] The specific operation process of this utility model is as follows: Insert the limiting stop 24 of the lifting lug body 2 into the lifting slot, and insert the two stop bodies 3 one by one into the through holes 26 of the two stop 22 of the lifting lug body 2, and simultaneously insert the stop bodies 3 into the corresponding lifting slots. Then, snap the four lifting lug bodies 2 one by one onto the four impact seats 4 of the base frame 1.

[0031] Cables are threaded through the lifting rings 23 of each lifting lug body 2 and the cables are attached to the lifting equipment. The lifting equipment then lifts the base frame 1.

[0032] During the lifting process, the limit stop 24 located on the outer side of the lifting slot tends to tilt upward. At this time, as the stop body 3 presses down on the anti-disengagement part, it drives the stop 22 to fit against the impact seat 4. Because the impact seats 4 are symmetrically arranged, the lateral force of the stop 22 relative to the base frame 1 cancels each other out, which can prevent the limit stop 24 from falling out of the lifting slot. At the same time, the limit stop 24 exerts an upward force on the base frame 1 through the lifting slot, causing the base frame 1 to be lifted.

[0033] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0034] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
