Compared with the prior art, the high-strength energy-saving carriage flower hurdle for the cabin-grating truck or the semitrailer has the beneficial effects that:
1. In addition, 8 square pipes are placed at most in each time of 45-degree oblique angle cutting processing of the square pipes, the cutting difficulty is high, the cutting efficiency is low, and if more than 10 pipes are placed for simultaneous cutting, the cutting consistency is reduced, the cutting precision is poor, and the rejection rate is increased.

Even if the right angle cutting and the 45 degree bevel cutting are compared under the same condition, the rejection rate of the 45 degree bevel cutting is higher.
2. In the prior art, the upper frame, the lower frame and the vertical frame of the 45-degree bevel butt welding have to be consistent in tubular section size, otherwise, the welding surfaces cannot be symmetrical, the welding processing difficulty is high, and the adaptability is poor. The invention adopts right-angle welding, can randomly combine hollow square pipes or rectangular pipes with different section sizes, has more flexible processing and wide application, and is suitable for carriages with various strength requirements.
3.

5. According to the invention, the liquid discharge holes are formed in the welding surfaces of the side surfaces of the two ends of the vertical frame, the liquid discharge holes are semicircular or arched, the right-angle sides of the liquid discharge holes are combined with the middle positions of the incision welding seams of the upper frame or the lower frame, the liquid can be smoothly discharged into the vertical frame from the upper frame or the lower frame without residues, the size of the liquid discharge holes is limited, and the size is designed according to the welding strength, so that the liquid discharge can be completely ensured under the condition of not affecting the welding strength, and the internal corrosion is prevented.
6. The reinforcing corner fitting wraps the vertical frame port, so that the round liquid discharge hole is formed in one side of the right-angle side of the end face of the reinforcing corner fitting, and the edge opening is formed, so that liquid can be completely discharged from the vertical frame, residual liquid is not generated, or backflow is avoided, the plugging defect existing in the right-angle welding design is overcome, and internal corrosion, particularly corrosion to welding seams of four corners, is prevented.

7. The invention has the advantages that the two ends of the vertical scale are provided with the vertical scale liquid discharge holes, so that liquid in the vertical scale can be smoothly discharged, and in addition, the horizontal scale is welded in a fully-closed manner, and the risk of internal corrosion is avoided, so that the horizontal scale is not provided with the liquid discharge holes.
8. According to the upper frame mounting hole, a hot-melt drilling technology is adopted, and the material of the base metal is remolded and extended to form a reinforcing structure (reinforcing pipe structure) around the hole in the drilling process, so that an additional welded steel pipe is not needed for reinforcing, the production efficiency is improved compared with the prior art, the production materials and the production procedures are saved, the production cost is greatly reduced, and the strength of the hot-melt integrally formed mounting hole is higher than that of the welded steel pipe. The reinforcing pipe structure is used for reinforcing the bearing force of the upper frame mounting hole after being inserted into the tarpaulin rod, the size of the upper frame mounting hole and the size of the reinforcing pipe structure are designed, and the design can achieve the reinforcing effect with the highest performance, so that the service life is greatly prolonged.
9. The hot melt drill of the mounting hole has the same drilling direction, namely the structure of the reinforcing pipe is consistent with the upper and lower surfaces of the upper frame pipe in the forward direction, namely the structure of the reinforcing pipe is consistent with the inserting direction of the tarpaulin rod, so that the tarpaulin rod is not blocked from being inserted due to barbs formed at the ports of the hot melt reinforcing structure during hot melt drilling, and the smooth inserting effect is better.
10. The hot-melt drilling processing of the invention can be processed by a multi-hole special machine, all holes on the symmetrical surface of one pipe can be processed at one time, and the full-automatic processing of feeding and discharging can be realized by matching with an automatic feeding and discharging device. High production efficiency and greatly reduced production cost.
11. The vertical frame liquid discharge holes and the reinforced corner piece liquid discharge holes are arranged at the edges of the corresponding pipe orifices, the edges are provided with the liquid discharge holes which can smoothly discharge liquid, if the small liquid discharge holes are arranged in the middle, the edges can obstruct the liquid flow or generate backflow phenomenon, the liquid can not be completely discharged, the special structure arrangement of a series of liquid discharge holes is designed for the right-angle welding process, and the special structure arrangement has the effect of further improving the usability of the right-angle welding flower hurdle frame.
