DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The following is a detailed description of the utility model through specific embodiments. Those who understand this technology can easily understand other advantages and effects of the utility model from the content disclosed in this specification; it should be noted, however, that the following specific embodiments do not technically limit the technical solution, and those skilled in the art can make further technical extensions under the guidance of the following technical solutions. The protection scope of this patent application shall be subject to the claims.

[0031] In this embodiment, it should be noted that since the LFT-D pallet is made of fiber-reinforced thermoplastic composite material, when it bears a large load, it has a large bending deflection and is in a continuous creep state. In some cases, the pallet is often placed on the shelf for more than 3 months, and the traditional LFT-D pallet application is not safe. In order to expand the application of LFT-D pallets in these cases and to withstand a large shelf load, an LFT-D steel-plastic composite pallet is used.

[0032] As Figure 1 , 2 shown, an LFT-D steel-plastic composite pallet includes a pallet body 1 and a connecting rod assembly;

[0033] The pallet body 1 is a plate body, and positioning protrusions 11 are arranged on the top surface of the plate body. In this embodiment, a positioning groove is formed by surrounding between the four positioning protrusions 11; support protrusions 12 are arranged at the bottom of the plate body, and an insertion slot 13 is formed between the support protrusions 12; the insertion slot 13 is used for the insertion of the forklift fork.

[0034] The connecting rod assembly includes multiple vertical fixing rods 2. Support frames 23 are arranged at the upper and lower ends of the fixing rod 2. The support frames 23 can extend at the upper and lower ends of the fixing rod 2 and can be locked by adjusting bolts 22. This structural design can realize the adjustment of different stretching lengths on the connecting rod assembly, can be applied to the fixing of charging piles with different heights, and can achieve axial compression to ensure the stability of the internal fixed charging pile during transportation.

[0035] In this embodiment, the multiple fixing rods 2 are connected and fixed by longitudinal rods 21. This structure can overall improve the strength of the connecting rod assembly.

[0036] A connecting part 24 in the horizontal direction is arranged on the support frame 23, and the connection and fixation of the horizontal pressure rod 25 are realized through the connecting part 24. The horizontal pressure rod 25 is linked with the support frame 23 and the horizontal pressure rod 25 is arranged on the bottom surface of the plate body. Here, the plate body refers to the plate body of the pallet body 1.

[0037] Observed from the bottom of the pallet body 1, at least two horizontal pressure rods 25 are arranged front and back, and two or more horizontal pressure rods 25 are connected into one body by a connecting rod 26.

[0038] Furthermore, 9 groups of positioning grooves formed by surrounding between the positioning protrusions 11 are arranged on the top surface of the pallet body 1. Such positioning grooves are molded together with the pallet body 1, which is convenient for positioning and fixing when the charging pile product is placed. A fixing rubber pad can also be inserted into the positioning groove, and the placement and fixation of bases with various sizes can be realized through the rubber pad.

[0039] The bottom surface of the tray body 1 is provided with 9 groups of supporting protrusions 12 as convex leg structures, which are convenient for forklift insertion and use. The length of the supporting protrusion 12 is 210 mm, the width is 150 mm, and the thickness protruding from the bottom surface of the tray body 1 is 73 mm. For further strengthening, in the length direction and the width direction, the thickness of the rib parts around the supporting protrusion 12 is 2.5 mm to 4.0 mm. In the length and width directions, the width of the rib parts inside the supporting protrusion 12 is 2.5 mm to 4.0 mm, and the depth of the rib parts is 73 mm. Since the root of the supporting protrusion 12 is a stress concentration point, inclined ribs are arranged on the outer periphery for strengthening, and the thickness of the rib parts is 2.0 mm to 4.0 mm. Four strengthening ribs are arranged around the inner edge panel of the supporting protrusion 12, and the width of the rib parts is 4.5 mm to 5 mm.

[0040] The fixed rod 2 is a galvanized square pipe, the material is Q235, and the galvanized square pipe is at least coated with a thickness of 3 mm. The strength of the inside of the tray body 1 can be improved by embedding square pipes. In this embodiment, the number of embedded square pipes used is 4. One is embedded at the center position of the outer convex leg structure, and two are embedded at the center positions of the middle convex leg structures.

[0041] When two tray bodies 1 are stacked and screwed, the upper support frame 23 is locked to the upper tray body 1 through the locking bolt 27. A top positioning pressure cover 3 is arranged below the horizontal pressure rod 25 of the upper support frame 23. Positioning grooves 32 are arranged at the four corners of the bottom surface of the top positioning pressure cover 3, and positioning protrusions 31 are arranged on the top surface of the top positioning pressure cover 3. The positioning protrusions 31 are spaced from the horizontal pressure rod 25 or the supporting protrusion 12.

[0042] When the utility model is in use:

[0043] (1) Support frames 23 are arranged at the upper and lower ends of the fixed rod 2, and the upper support frame 23 is linked with the upper tray body 1, and the adaptation height of the charging pile can be manually adjusted;

[0044] (2) The support frames 23 at the upper and lower ends of the fixed rod 2 can be adjusted and locked to realize reliable fixation when two tray bodies 1 are stacked and screwed;

[0045] (3) A longitudinal rod 21 is arranged in the middle of the fixed rod 2, and a horizontal pressure rod 25 and a connecting rod 26 are arranged at the bottom of the fixed rod 2. Through multiple locking structures, the shaking of the bracket is prevented.

[0046] The utility model provides an LFT-D steel-plastic composite tray device for the turnover of charging piles. The LFT-D material is combined with steel pipes, giving play to the characteristics of the LFT-D material of being light in weight and high in strength. The load-bearing capacity is greatly improved, and the use is safe and reliable. The placement of multiple charging piles is realized through the middle support structure. This scheme has a high cost performance and is suitable for large-scale promotion.
