[0027] The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be understood as limiting the present application.

[0028] like Figures 1 to 3 As shown, this embodiment provides a traction structure of a powder tank truck, including: a traction plate 1 and a traction connecting plate 2, wherein the traction connecting plate 2 is connected to the traction plate 1 and is stacked on the traction plate 1 along the height direction of the powder tank truck.

[0029] In this embodiment, the traction plate 1 and the traction connecting plate 2 are connected by using hexagon socket countersunk bolts g. The hexagon socket countersunk bolts g are used to connect the traction plate 1 and the traction connecting plate 2, so that the hexagon socket countersunk bolts g will not protrude relative to the plate surface, which is beneficial to ensure the flatness of the plate surface; and the hexagon socket countersunk bolts g can withstand greater loads and are less likely to be damaged.

[0030] Combination Figure 1 As shown, the traction structure of the powder tank truck also includes two webs 3, a front sealing plate 4 and a first buckle box 5. The two webs 3 are connected to the two ends of the front sealing plate 4 one by one along the wheelbase direction of the powder tank truck. The two webs 3 and the front sealing plate 4 are connected to the traction connecting plate 2 and are located on the side of the traction connecting plate 2 away from the traction plate 1 along the height direction of the powder tank truck. The two webs 3 and the front sealing plate 4 are used to connect the tank body f of the powder tank truck along the side of the height direction of the powder tank truck away from the traction connecting plate 2, and the two webs 3 and the front sealing plate 4 form a reinforced cavity h between the tank body f and the traction connecting plate 2; the front sealing plate 4 and the web 3 have an overlapping area along the wheelbase direction of the powder tank truck, and part of the front sealing plate 4 and part of the web 3 in the overlapping area are fitted together; the first buckle box 5 is connected to part of the front sealing plate 4 and part of the web 3 in the overlapping area, and is connected to the traction connecting plate 2.

[0031] In this embodiment, firstly, a traction connecting plate 2 is arranged above the traction plate 1, so that the strength of the traction plate 1 is increased, thereby increasing the torsion resistance of the traction structure. Secondly, the two webs 3 and the front sealing plate 4 connect the tank body f and the traction connecting plate 2 to form a reinforced cavity h, which can increase the stability and torsion resistance of the traction structure. Then, the front sealing plate 4 and the web 3 have an overlapping area, and part of the front sealing plate 4 and part of the web 3 in the overlapping area are in contact, increasing the contact area between the front sealing plate 4 and the web 3, and reducing the probability of cracking of the front sealing plate 4 and the web 3. Finally, since the first buckle box 5 is connected to part of the front sealing plate 4 and part of the web 3 in the overlapping area, and is connected to the traction connecting plate 2, the first buckle box 5 has a certain reinforcement effect on the connection between part of the front sealing plate 4 and part of the web 3 in the overlapping area, and can reduce the probability of cracking of the front sealing plate 4 and the web 3; at the same time, the box-like structure formed after the first buckle box 5 is connected to the traction connecting plate 2 can absorb part of the traction force and increase the torsional resistance of the traction structure.

[0032] In summary, the traction structure of the powder tank truck of the utility model can not only reduce the probability of cracking and the like, but also increase the stability and torsion resistance of the traction structure.

[0033] Combination Figure 1 and Figure 3 As shown, the traction plate 1 includes a first connection area 11 and a second connection area 12 along the wheelbase direction of the powder tanker, and the second connection area 12 includes a left connection area 121, a middle area 122 and a right connection area 123 along the wheelbase direction of the powder tanker, and the middle area 122 is located between the left connection area 121 and the right connection area 123, and the left connection area 121, the right connection area 123 and the middle area 122 are all arranged opposite to the first connection area 11 along the wheelbase direction of the powder tanker; wherein, the traction connection plate 2 is located in the first connection area 11 and the middle area 122; the traction structure also includes two lower wing plates 6, and the two lower wing plates 6 are located in the left connection area 121 and the right connection area 123 one by one, and are connected to both the traction connection plate 2 and the traction plate 1.

[0034] In this embodiment, the traction connecting plate 2 is located in the first connecting area 11 and the middle area 122; the two lower wing plates 6 are located in the left connecting area 121 and the right connecting area 123 respectively, and are connected to the traction connecting plate 2 and the traction plate 1, that is, the traction connecting plate 2 and the lower wing plate 6 are welded by plug-in connection, which changes the force path of the traction plate 1 and the traction connecting plate 2 and reduces the probability of cracking of the lower wing plate 6.

[0035] It should be understood that the middle area 122 of the traction plate 1 is the main force-bearing area of ​​traction, and the two lower wing plates 6 are located in the left connection area 121 and the right connection area 123 respectively, and are not located in the middle area 122, so as to avoid cracking of the lower wing plates 6 when subjected to traction.

[0036] In this embodiment, combined with Figure 3 As shown, the orthographic projection of the lower wing plate 6 in the right connection area 123 or the left connection area 121 is a trapezoid, so that the contact area of ​​the welding between the traction connecting plate 2 and the lower wing plate 6 is larger, which is beneficial to increase the stability of the traction structure.

[0037] It should be understood that the lower wing plate 6 is the frame of the powder tanker, and the lower wing plate 6 is connected to both the traction connecting plate 2 and the traction plate 1, thereby enhancing the torsion resistance and stability of the traction structure.

[0038] Combination Figure 1 and Figure 2 As shown, the traction structure also includes a traction pin 7, which passes through the traction connecting plate 2 and the traction plate 1 and is located in the middle position between the two webs 3; the traction structure also includes a second buckle box 8, which is connected to the traction pin 7 and the traction connecting plate 2, and covers the traction pin 7 and the traction connecting plate 2.

[0039] In this embodiment, the second buckle box 8 is a steel plate structure with high strength and durability. The second buckle box 8 is covered on the traction pin 7 and the traction connecting plate 2 along the height direction of the powder tanker. The second buckle box 8 can improve the firmness of the traction pin 7 fixed on the traction plate 1 and the traction connecting plate 2, thereby ensuring the connection strength of the tractor of the powder tanker and the trailer of the powder tanker. The second buckle box 8 is connected to the traction pin 7 by a broken welding method, and the sharp corners of the second buckle box 8 are welded with a fillet welding style to reduce the probability of cracking at the sharp corners of the second buckle box 8.

[0040] It should be understood that the towing pin 7 is a part of the trailer and is used to connect the tractor and the trailer. After the fifth wheel of the tractor is connected to the towing pin 7 of the trailer, the tractor drags the trailer to move.

[0041] Combination Figure 1 and Figure 2 As shown, the traction structure also includes a first crossbeam a and a second crossbeam b spaced apart from each other, the first crossbeam a and the second crossbeam b are both located in the reinforcement cavity h and connected to the traction connecting plate 2, the first crossbeam a is located in the front sealing plate 4 along the wheelbase direction of the powder tank truck, and the second crossbeam b is connected between the two webs 3; the traction structure also includes two longitudinal beams c spaced apart from each other, the two longitudinal beams c are both located in the reinforcement cavity h and connected to the traction connecting plate 2, and the two longitudinal beams c are both connected between the first crossbeam a and the second crossbeam b; wherein the traction pin 7 is located between the first crossbeam a and the second crossbeam b, and between the two longitudinal beams c.

[0042] In this embodiment, the first cross beam a, the second cross beam b and the two longitudinal beams c are in a "well-shaped structure" and are all connected to the traction connecting plate 2, which can increase the torsional resistance of the traction structure; the traction pin 7 is located between the first cross beam a and the second cross beam b, and between the two longitudinal beams c, so that the force on the traction structure is more uniform, and the traction force exerted on the traction pin 7 can be transmitted to the first cross beam a, the second cross beam b and the two longitudinal beams c, and the traction force is dispersed to other components, which is beneficial to ensuring the overall stability of the traction structure.

[0043] Combination Figure 1 As shown, the first cross beam a is a "C-shaped" structure, and the opening of the first cross beam a is located on the side facing the front cover plate 4; wherein the height of the first cross beam a is greater than the heights of the second cross beam b and the two longitudinal beams c.

[0044] In this embodiment, in order to maintain the fit with the front cover 4, the first cross beam a is set to a "C-shaped" structure, and the opening is located on the side facing the front cover 4, which can increase the torsional resistance of the traction structure; at the same time, the height of the first cross beam a is greater than the height of the second cross beam b and the two longitudinal beams c, that is, increasing the height of the first cross beam a. Raising the first cross beam a can also play a role in increasing the torsional resistance of the traction structure.

[0045] Combination Figure 1 and Figure 2 As shown, the traction structure also includes two third buckle boxes 9 spaced apart from each other. The two third buckle boxes 9 are both located in the reinforcement cavity h. The two third buckle boxes 9 are connected to the side of the second beam b away from the first beam a and are connected to the traction connecting plate 2.

[0046] In this embodiment, the third buckle box 9 is a "trapezoidal" structure, one end of the third buckle box 9 is connected to the side of the second beam b away from the first beam a, and the other end is connected to the traction connecting plate 2. The third buckle box 9 performs folding treatment on the sharp corners of contact between the second beam b and the traction connecting plate 2 to avoid cracking at the sharp corners, so as to ensure the stability and torsion resistance of the powder tanker during driving.

[0047] Combination Figure 1 and Figure 2 As shown, the traction structure also includes two third beams d spaced apart from each other. The two third beams d are both located in the reinforcement cavity h and between the first buckle box 5 and the second beam b. The third beam d is connected between the web 3 and the longitudinal beam c, and covers the connection position of the lower wing plate 6 and the traction connecting plate 2.

[0048] It should be understood that the traction structure includes two webs 3 and two longitudinal beams c, and all are symmetrically arranged along the wheelbase direction of the powder tanker. Therefore, a third cross beam d is connected between a web 3 and a longitudinal beam c adjacent to the web 3, and another third cross beam d is connected between another web 3 and a longitudinal beam c adjacent to the web 3.

[0049] In this embodiment, the two third cross beams d are symmetrically arranged along the wheelbase direction of the powder tanker, and are both covered at the connection position of the lower wing plate 6 and the traction connecting plate 2, which can avoid cracking at the connection position of the lower wing plate 6 and the traction connecting plate 2 and increase the stability of the traction structure.

[0050] Combination Figure 1 As shown, the traction structure also includes two fourth beams e, which are spaced apart from each other and located in the reinforcement cavity h. One of the two fourth beams e is connected between the third beam d and the tank body f, and the other is connected between the second beam b and the tank body f.

[0051] In this embodiment, the two fourth cross beams e are both "Z-shaped" structures, the two fourth cross beams e are both located in the reinforcement cavity h, and one end of the two fourth cross beams e is connected to the tank body f of the powder tank truck, so that the two fourth cross beams e and the tank body f form a reinforcement structure, which can increase the torsional resistance of the traction structure.

[0052] Combination Figure 2 As shown, the front sealing plate 4 is an arc structure.

[0053] In this embodiment, the front sealing plate 4 is made of a complete plate surface by bending, and the front sealing plate 4 is set to an arc structure, which not only increases the contact area between the front sealing plate 4 and the tank body f for welding, improves the strength of the traction structure, but also avoids the problem of easy cracking at sharp corners, thereby ensuring the stability of the powder tanker during driving; therefore, after the strength of the traction structure is increased by making the front sealing plate 4 into an arc structure, the thickness of the front sealing plate 4 can be appropriately reduced, thereby reducing the dead weight.

[0054] For example, the front sealing plate 4 can be configured to be semicircular, U-shaped, or the like.

[0055] In this embodiment, the traction plate 1 is a steel plate structure, that is, the traction plate 1 is made of a steel plate, so that the traction plate 1 is more wear-resistant.

[0056] It should be understood that, during the driving process of the powder tank truck, the traction plate 1 will be worn after being connected to the traction seat of the traction vehicle. The traction plate 1 is more wear-resistant and can effectively extend the service life of the traction plate 1.

[0057] In summary, after the traction plate 1 and the traction connecting plate 2 are connected by bolts, the traction connecting plate 2 is welded with the first buckle box 5, the traction pin 7, the second buckle box 8, the third buckle box 9, the first crossbeam a, the second crossbeam b, the third crossbeam d, the fourth crossbeam e and the longitudinal beam c and other accessories in sequence to strengthen the overall traction structure, and then welded with the lower wing plate 6 by plug-in, and then the web 3 and the frame of the powder tank truck are welded and merged, and finally the front cover plate 4 and the web 3 are welded together to form an overall traction structure.

[0058] This embodiment further provides a vehicle, comprising a vehicle head and the above-mentioned traction structure of the powder tank truck, wherein the vehicle head is connected to the traction structure of the powder tank truck.
