[0028] like Figures 1 to 5 As shown, a heat preservation transport vehicle upper cover structure includes an upper cover plate 1, a connecting rod mechanism 4 and a sealing strip 2;

[0029] Two sets of upper covers 1 are symmetrically arranged above the carriage, each set of upper covers 1 includes a hinged first cover 11 and a second cover 12, the first cover 11 is hinged to the long side of the carriage; the connecting rod mechanism 4 is installed between the carriage and the upper covers 1, and the multiple connecting rod mechanisms 4 are used to drive the upper covers 1 to open or close;

[0030] The sealing strip 2 includes a rectangular sealing strip 21 installed above the upper cover plate 1 and a P-shaped sealing strip 22 installed below the upper cover plate 1. The rectangular sealing strip 21 is mainly used to prevent liquids such as rainwater from entering the interior of the vehicle, and the P-shaped sealing strip 22 is mainly used to prevent heat loss inside the vehicle.

[0031] In some embodiments, as Figure 1 As shown, a plurality of hinge seats 5 are installed on the carriage, and the first cover plate 11 is hinged on the hinge seat 5 through a pin or a bolt. Under the drive of the connecting rod mechanism 4, the upper cover plate 1 can be controlled to rotate and open along the carriage hinge.

[0032] In some embodiments, as Figure 2 As shown, the connecting rod mechanism 4 includes a first connecting rod 41, a second connecting rod 42, a hydraulic cylinder 43 and a third connecting rod 44 installed on the front side of the carriage;

[0033] The second connecting rod 42, hydraulic cylinder 43, and third connecting rod 44 are each hinged to the carriage at one end. The other end of the second connecting rod 42 is hinged to the second cover plate 12. The other end of the hydraulic cylinder 43 and the other end of the third connecting rod 44 are hinged to each other. One end of the first connecting rod 41 is hinged to the second connecting rod 42, and the other end is connected to the hinge point between the hydraulic cylinder 43 and the third connecting rod 44. The connecting rod mechanism 4 is driven by the extension and contraction of the hydraulic cylinder 43, which controls the rotation of the planar four-bar mechanism composed of the connecting rods and the upper cover plate 1, thereby realizing the opening and closing function of the upper cover plate 1.

[0034] In some embodiments, as Figure 1 、 Figure 3 As shown, it also includes a fourth connecting rod 45 installed on the rear side of the car body, one end of the fourth connecting rod 45 is hinged to the car body, and the other end is hinged to the second cover plate 12. The first connecting rod 41, the second connecting rod 42 and the third connecting rod 44 are driven by the hydraulic cylinder 43, and the upper cover plate 1 is opened or closed through the cooperation of the fourth connecting rod 45.

[0035] In some embodiments, as Figures 1 to 3 、 Figure 5 As shown, the first cover plate 11 is provided with a plurality of anti-collision and shock absorbing blocks 3, which are installed on the first cover plate 11 and close to one side of the vehicle compartment. When the upper cover plate 1 is opened, as shown in FIG. Figure 3 As shown, the anti-collision and shock-absorbing block 3 on the first cover plate 11 contacts the outer side plate of the vehicle compartment to prevent the upper cover plate 1 from directly hitting the vehicle compartment when opening, thereby preventing deformation.

[0036] In some embodiments, the sealing strip 2 is made of any one of rubber, canvas or silicone, which has low cost and is easy to process.

[0037] In some embodiments, as Figure 4 As shown, the rectangular sealing strip 21 is installed in the gap between the first cover plate 11 and the second cover plate 12 and the gap where the two second cover plates 12 contact each other. When the upper cover plate 1 is opened, rainwater or debris can slide along the sealing strip and the upper cover plate 1 to prevent them from entering the interior of the vehicle. When the upper cover plate 1 is closed, a good sealing effect can also be formed to effectively prevent liquid leakage and provide windproof function.

[0038] like Figure 5 As shown, the P-shaped sealing strip 22 is installed on the first cover plate 11 near the gap between the first cover plate 11 and the vehicle compartment, the gap between the first cover plate 11 and the second cover plate 12, and the gap where the two second cover plates 12 come into contact. The rectangular edge of the P-shaped sealing strip 22 faces the outside of the upper cover plate, and the circular edge faces the inside of the upper cover plate to achieve a sealing and heat-insulating effect. The rectangular edge of the P-shaped sealing strip 22 is fixed to the upper cover plate by a pressure strip to prevent slipping. When the upper cover plate 1 is in the closed state, the P-shaped sealing strip 22 can effectively seal the gap between the vehicle compartment and the upper cover plate 1, thereby effectively preventing heat loss from the interior of the vehicle compartment and achieving a good heat-insulating effect.

[0039] In some embodiments, the first cover plate 11 and the second cover plate 12 are both provided with an insulation layer inside, and the insulation layer is filled with insulation material, which can further improve the insulation performance of the upper cover structure of the insulated transport vehicle.

[0040] The second aspect of the present invention further provides a heat-insulating transport vehicle, on which the heat-insulating transport vehicle upper cover structure is installed.

[0041] When the insulated transport vehicle is transporting over long distances in a low-temperature environment, the hydraulic cylinder 43 in the connecting rod mechanism 4 drives the first connecting rod 41, the second connecting rod 42 and the third connecting rod 44 to rotate, and drives the fourth connecting rod 5 to rotate, so that the two upper cover plates 1 are closed above the carriage. Relying on the multiple rectangular sealing strips 21 and P-shaped sealing strips 22 on the upper cover plates 1, it plays a role in preventing liquids such as rainwater from entering the interior of the carriage and preventing heat loss inside the carriage.

[0042] The upper cover structure of the heat-insulating transport vehicle of the present invention adopts two groups of upper cover plates hinged to the carriage, and the upper cover plates themselves can also be hinged and rotated, so that the upper cover plates can be flexibly opened or closed on the carriage, thereby providing good flexibility and adjustability; the connecting rod mechanism adopted is driven by a hydraulic cylinder, which can smoothly control the opening and closing of the upper cover plates, thereby improving the convenience and efficiency of operation; the sealing strip adopted can effectively prevent wind and liquid from penetrating into the carriage, while preventing heat loss, thereby improving the sealing and heat preservation effect inside the carriage.

[0043] The utility model provides effective structural protection, is easy to operate, has high flexibility, and has good sealing performance.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
