[0026] To improve or resolve the technical issues of low structural strength of support plates in the prior art, which pose a risk of deformation and damage due to long-term use, the present utility model provides a bottom support structure for a powder tanker truck. The bottom support structure for a powder tanker truck comprises a support frame 1 and two support legs 2 mounted at each end of the support frame 1. The support frame 1 includes a mounting portion 11 fixedly connected to the support legs 2 and adapted to connect to a longitudinal beam 100, and a connecting portion 12 connected to the mounting portion 11. The mounting portion 11 is larger than the connecting portion 12, and a reinforcing guard plate 3 adapted to connect to the longitudinal beam 100 is disposed on the mounting portion 11.

[0027] Figure 1 This is a schematic diagram of an embodiment of the bottom support structure of a powder tank truck according to the present invention. Figure 1 As shown, in one or more embodiments, the bottom support structure of the powder tank truck of the present invention includes a support frame 1 and support legs 2 installed at both ends of the support frame 1.

[0028] Figure 2 This is a schematic diagram of the support frame in the bottom support structure of the powder tank truck of the utility model. Figure 3 This is another schematic diagram of the support frame in the bottom support structure of the powder tank truck of the utility model. Figure 1 、 Figure 2 and Figure 3 As shown, in one or more embodiments, the support frame 1 includes a mounting portion 11 and a connecting portion 12 connected to the mounting portion 11. Two mounting portions 11 are provided, and the two mounting portions 11 are respectively connected to the two supporting legs 2; the connecting portion 12 connects the two mounting portions 11. Specifically, the connecting portion 12 and the mounting portion 11 are both roughly I-beam-shaped, and the size of the mounting portion 11 is larger than the size of the connecting portion 12. Exemplarily, the height and width of the mounting portion 11 are 1.5 times the height and width of the connecting portion 12. Alternatively, the size relationship between the mounting portion 11 and the connecting portion 12 can also be set to other suitable proportions. Further, the mounting portion 11 includes a top horizontal plate 111, a bottom horizontal plate 112 and a vertical plate 113. The top transverse plate 111 and the bottom transverse plate 112 are roughly rectangular plates, and the top transverse plate 111 and the bottom transverse plate 112 are arranged relatively parallel to each other. The vertical plate 113 connects the top transverse plate 111 and the bottom transverse plate 112, and the two ends of the vertical plate 113 are respectively located in the middle of the top transverse plate 111 and the bottom transverse plate 112. Furthermore, a mounting plate 14 is arranged on the side of the mounting portion 11 close to the support leg 2. The mounting plate 14 is roughly rectangular plate, and mounting holes are opened on the mounting plate 14. The mounting holes are arranged in two rows, and each row has multiple mounting holes. Furthermore, the mounting plate 14 is fixedly connected to the mounting portion 11 by welding, and the mounting plate 14 is fixedly connected to the support leg 2 by a bolt structure.

[0029] Continue to participate Figure 1 、 Figure 2 and Figure 3 In one or more embodiments, a transition portion 13 is provided between the connecting portion 12 and the mounting portion 11. The transition portion 13 extends from the mounting portion 11 toward the center of the connecting portion 12. That is, the transition portion 13 is roughly in the shape of a quadrangular pyramid. Specifically, the transition portion 13 includes a top cone plate 131, a bottom cone plate 132 arranged as a mirror image of the top cone plate 131, and a middle plate 133 connecting the top cone plate 131 and the bottom cone plate 132. The top cone plate 131 is roughly in the shape of an isosceles trapezoid and has opposite large and small ends. The large end is connected to the mounting portion 11, and the small end is connected to the connecting portion 12. The dimensions of the connecting portion 12 are smaller than those of the mounting portion 11, so the top cone plate 131 extends obliquely downward from the mounting portion 11 and toward the center of the connecting portion 12. The bottom cone plate 132 and the top cone plate 131 are symmetrically arranged about the transverse centerline of the support frame 1. Furthermore, a plurality of weight-reducing holes 15 are evenly spaced and arranged on the support frame 1. The weight-reducing holes 15 are provided on the mounting portion 11, the transition portion 13 and the connecting portion 12. For example, one weight-reducing hole 15 is provided on the mounting portion 11, one weight-reducing hole 15 is provided on the transition portion 13, and five weight-reducing holes 15 are provided on the connecting portion 12.

[0030] Continue to see Figure 1 、 Figure 2 and Figure 3 In one or more embodiments, a reinforcing guard plate 3 suitable for connecting to the longitudinal beam 100 is arranged on the mounting portion 11. The reinforcing guard plate 3 is fixedly connected to the mounting portion 11 and is connected to the longitudinal beam 100, thereby enhancing the strength and rigidity of the connection between the mounting portion 11 and the longitudinal beam 100, and at the same time enhancing the connection strength between the support frame 1 and the longitudinal beam 100. Specifically, the reinforcing guard plate 3 is fixedly connected to the top transverse plate 111, the bottom transverse plate 112 and the vertical plate 113. The reinforcing guard plate 3 is roughly in the shape of a right-angled trapezoid, and the two reinforcing guard plates 3 are symmetrically arranged along the vertical plate 113. The upper side surface of the reinforcing guard plate 3 is connected to the top transverse plate 111, and extends from the top transverse plate 111 to connect to the longitudinal beam 100. An avoidance groove 33 matching the top transverse plate 111 is provided on the upper side surface, so that the upper side surface of the reinforcing guard plate 3 is flush with the top surface of the top transverse plate 111. Furthermore, the reinforcement guard plate 3 includes a first guard plate 31 close to the support leg 2 and a second guard plate 32 arranged parallel to the first guard plate 31. The two guard plates can further enhance the strength and rigidity of the connection between the mounting portion 11 and the longitudinal beam 100.

[0031] Figure 4 This is a schematic diagram of the support legs in the bottom support structure of the powder tank truck of the utility model. Figure 1 and Figure 4As shown, in one or more embodiments, the support legs 2 are manually cranked and fixedly connected to the support frame 1 via bolts. The support legs 2 are driven by gears, and when the powder tanker requires support, the support frame 1 is raised or lowered by a manually cranked handle. Two support legs 2 are provided, each controlled independently. Furthermore, a hook is provided on the support frame 1 for receiving the crank handle.
