DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figures 1 to 5 As shown, in this embodiment, a quick disassembly and assembly fastening device for a dump truck includes a front 1, a frame 2 is provided at the rear end of the front 1, a compartment 3 is provided at the upper end of the frame 2, the bottom of the rear end of the compartment 3 is rotatably connected to the frame 2 through a rotating assembly, a flip mechanism acting on the compartment 3 is provided on the frame 2, a baffle 4 is provided at the rear end opening position of the compartment 3, the baffle 4 is connected to the compartment 3 through an automatic opening and closing mechanism, and the automatic opening and closing mechanism is composed of two automatic opening and closing assemblies, and the two automatic opening and closing assemblies are symmetrically distributed at the rear end of the compartment 3. On both sides, the automatic opening and closing assembly consists of a No. 1 connecting rod 9, a No. 1 rotating shaft 10, a No. 2 connecting rod 11 and a No. 2 rotating shaft 12. The No. 1 connecting rod 9 is located at the top of the side end of the carriage 3. The No. 1 connecting rod 9 is rotatably connected to the carriage 3 through the No. 1 rotating shaft 10. One end of the No. 1 connecting rod 9 is fixedly connected to the baffle 4. The other end of the No. 1 connecting rod 9 is rotatably connected to the No. 2 connecting rod 11. The other end of the No. 2 connecting rod 11 is rotatably connected to the No. 2 rotating shaft 12. The No. 2 rotating shaft 12 is fixedly connected to the side wall of the frame 2.

[0022] The two sides of the baffle 4 are respectively fixedly connected with side plates 17 , and the distance between the two side plates 17 is equal to the width of the carriage 3 .

[0023] By providing the side panels 17 , it can be ensured that after the baffle 4 is closed, the two side panels 17 can surround the two sides of the carriage 3 .

[0024] A sealing strip 16 is fixedly connected to the bottom of the side wall of the baffle 4 close to the carriage 3 , and a sealing groove 15 matched with the sealing strip 16 is provided at the bottom of the rear end of the carriage 3 .

[0025] With such arrangement, when the baffle 4 is closed, the sealing strip 16 on the baffle 4 will be embedded in the sealing groove 15 on the carriage 3, thereby ensuring that no leakage will occur at the connection position between the baffle 4 and the bottom of the carriage 3.

[0026] A plurality of cushion blocks 8 are fixedly connected to the upper end of the frame 2 .

[0027] The bottom of the carriage 3 can be supported by the provided cushion block 8 to ensure that the carriage 3 can be placed horizontally on the frame 2 .

[0028] Among them, the rotating assembly is composed of a connecting plate 13 and a No. 3 rotating shaft 14. The two No. 3 rotating shafts 14 are symmetrically distributed on both sides of the frame 2. The two No. 3 rotating shafts 14 are fixedly connected to the frame 2. The two No. 3 rotating shafts 14 are rotatably connected with a connecting plate 13, and the upper end of the connecting plate 13 is fixedly connected to the bottom of the carriage 3.

[0029] The connection plate 13 and the third rotating shaft 14 can ensure that the rear end of the carriage 3 is rotationally connected to the frame 2 .

[0030] Among them, the flipping mechanism is composed of a slider 5, a U-shaped plate 6 and a cylinder 7. The cylinder 7 passes through the frame 2 and is fixedly connected to the frame 2. The end of the telescopic rod of the cylinder 7 is rotatably connected to the U-shaped plate 6. The upper end of the U-shaped plate 6 is fixedly connected to the slider 5. The slider 5 is slidably installed in a slide groove opened at the bottom of the carriage 3.

[0031] When in use, the movable end of the carriage 3 is lifted up by extending the length of the telescopic rod of the cylinder 7, thereby realizing the overturning of the carriage 3.

[0032] The utility model provides a quick disassembly and assembly fastening device for a dump truck, and the specific working principle is as follows:

[0033] When in use, the movable end of the carriage 3 is lifted up by extending the length of the telescopic rod of the cylinder 7, thereby realizing the flipping of the carriage 3. When the carriage 3 flips, the first rotating shaft 10 will move synchronously with the carriage 3, so that the angle between the first connecting rod 9 and the second connecting rod 11 increases (refer to Figure 5 ), at this time, the No. 1 connecting rod 9 will tilt upward toward the rear end of the car 3, and the inclination of the No. 1 connecting rod 9 will cause the baffle 4 to tilt up, thereby automatically releasing the connection between the baffle 4 and the car 3. At this time, the materials in the car 3 can fall along the tilted car 3. When it is necessary to lock the baffle 4 at the rear end of the car 3, it is only necessary to shorten the length of the telescopic rod of the cylinder 7 to restore the car 3 to its initial position. Under the action of the No. 1 connecting rod 9 and the No. 2 connecting rod 11, the baffle 4 will seal the rear end of the car 3. At the same time, the baffle 4 will be restricted by the No. 1 connecting rod 9 and the No. 2 connecting rod 11 and cannot move (as long as the car 3 is not flipped, the baffle 4 will not move), thereby automatically completing the fastening measures of the baffle 4.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
