Description

Technical Field

[0001] The utility model relates to the technical field of dump trucks, in particular to a fastening device for a cargo compartment of a side-overturning dump truck. Background Art

[0002] A dump truck refers to a vehicle that unloads goods by itself through hydraulic or mechanical lifting. Traditional dump trucks are generally composed of components such as a car chassis, a hydraulic lifting mechanism, a cargo compartment and a power take-off device. There are two types: rear-tilting and side-tilting, namely: rear-tilting dump trucks and side-tilting dump trucks. Both rear-tilting dump trucks and side-tilting dump trucks lift the cargo compartment as a whole to unload goods. Side-tilting dump trucks have one side panel of the cargo compartment made into multiple movable doors. When unloading, the hydraulic lifting mechanism lifts, one side of the cargo compartment is jacked up, and the cargo compartment as a whole tilts to one side, and the goods in the cargo compartment are unloaded from the movable door on one side of the cargo compartment.

[0003] In the prior art, one side of the dump truck cargo box is hinged to the seat, and the other side is rotatably connected to the piston rod of the hydraulic lifting mechanism to achieve side-tipping automatic unloading. This semi-active connection method easily causes the cargo box to shake slightly when the truck is bumped during driving. Long-term shaking of the cargo box can easily lead to loosening of the hinge between the cargo box and the seat, ultimately affecting the safety of truck transportation and driving.

The abutting blocks 14 are slidably connected to the inserting rods 10. A first damping rod 15 is provided in the inserting rod 10. The two abutting blocks 14 are respectively movably clamped with the corresponding card seats 3. There are two groups of cross-distributed connecting rods 6 in the mounting groove 4. Sliders 7 are rotatably mounted at both ends of the two connecting rods 6. Slide rods 8 are provided in both the mounting rod 5 and the mounting groove 4. A third spring 9 is sleeved on the slide rod 8. Two built-in grooves 17 are opened on the vehicle seat 1. Four groups of symmetrically distributed circular card slots 19 are opened below the cargo box 2. Fixed seats 18 are provided in both of the two built-in grooves 17. Two groups of clamping blocks 21 are symmetrically distributed in both of the two fixed seats 18. The circular card slots 19 are correspondingly arranged with the clamping blocks 21. The clamping blocks 21 are movably clamped with the circular card slots 19 through insertion holes 20. The bidirectional lead screw 11 is rotatably connected to the mounting rod 5 through a bearing. Both ends of the bidirectional lead screw 11 respectively penetrate through the two inserting rods 10 and are threadedly connected to the two inserting rods 10. Both ends of the first damping rod 15 are respectively fixed to the inserting rod 10 and the abutting block 14. A first spring 16 is sleeved on the first damping rod 15. A first bevel gear 12 is sleeved on the bidirectional lead screw 11. A second bevel gear 13 is provided in the mounting rod 5. The second bevel gear 13 is rotatably connected to the mounting rod 5 through a rotating shaft. The second bevel gear 13 is meshed with the first bevel gear 12.

[0025] Through the arranged inserting rods 10, card seats 3 and two groups of cross-distributed connecting rods 6, etc., the fastening work of the cargo box 2 after being laid flat is realized. And on the basis of fastening the cargo box 2, the first spring 16 and the third spring 9 are cooperated to realize the shock absorption protection of the cargo box 2 in the vertical and horizontal directions, reducing the up-and-down and left-and-right shaking of the cargo box 2 caused by the bump of the truck during transportation, which affects the driving safety of the vehicle; after the cargo box 2 is laid flat, start the motor to drive the rotation of the second bevel gear 13. The second bevel gear 13 drives the first bevel gear 12 to rotate and then drives the rotation of the bidirectional lead screw 11.

During the movement of the inserting rods 10, the abutting blocks 14 are driven to move synchronously until the abutting blocks 14 are inserted into the card seats 3, completing the preliminary fastening work of the cargo box 2. When the vehicle is bumped during driving, the shaking force generated on the cargo box 2 is absorbed and buffered through the first damping rod 15, the first spring 16, the connecting rods 6, the sliders 7 and the third spring 9 on the slide rod 8, reducing the shaking amplitude of the cargo box 2 on the vehicle seat 1.

[0026] As Figure 4 , Figure 5 , Figure 6 and Figure 7 shown, an insertion hole 20 is formed in the circular card slot 19.

Under the action of the driving chain 26 and the driving wheel 25, both groups of clamping blocks 21 rotate 90 degrees synchronously. The clamping block 21 completes the reinforcement of the cargo box 2 through the circular card slot 19. Start the cylinder 27 to drive the fixed seat 18 and the clamping block 21 to move downward. The abutting plate 22 contacts the bottom surface of the circular card slot 19 and compresses the second damping rod 23 and the second spring 24, realizing buffer protection while fastening the cargo box 2 and reducing the shaking of the cargo box 2 caused by bumps.

[0028] The utility model provides a fastening device for the cargo box of a side-tipping dump truck, and the specific working principle is as follows: After the cargo box 2 is laid flat, the motor is started to drive the rotation of the second bevel gear 13. The second bevel gear 13 drives the first bevel gear 12 to rotate, and then drives the rotation of the bidirectional lead screw 11. Under the limiting action of the mounting rod 5, the two groups of inserting rods 10 move outwards synchronously. During the movement of the inserting rods 10, the abutting blocks 14 move synchronously until the abutting blocks 14 are inserted into the clamping seats 3, completing the preliminary fastening work for the cargo box 2. When the vehicle is jolted during driving, the shaking force generated on the cargo box 2 is absorbed and buffered by the first damping rod 15, the first spring 16, the connecting rod 6, the slider 7 and the third spring 9 on the sliding rod 8, reducing the shaking amplitude of the cargo box 2 on the vehicle seat 1. After the cargo box 2 is laid flat, the clamping block 21 is inserted into the circular clamping groove 19 through the insertion hole 20. At this time, the clamping block 21 is movably connected with the circular clamping groove 19. The motor is started to drive the clamping block 21 to rotate 90 degrees. Under the action of the drive chain 26 and the drive wheel 25, the two groups of clamping blocks 21 rotate 90 degrees synchronously. The clamping block 21 completes the reinforcement of the cargo box 2 through the circular clamping groove 19. The air cylinder 27 is started to drive the fixed seat 18 and the clamping block 21 to move downwards. The abutting plate 22 contacts the bottom surface of the circular clamping groove 19 and compresses the second damping rod 23 and the second spring 24, realizing buffer protection while fastening the cargo box 2 and reducing the shaking of the cargo box 2 caused by bumps.
