DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] See also Figures 1 to 5 The utility model provides a technical solution: a new type of counterweight device suitable for dump trucks, including a placing base 1 and a counterweight body 2. The total weight of the placing base 1, the counterweight body 2 and the additional structure is one ton. Since the load capacity of the dump truck is greater than one ton, a one-ton counterweight device is used for convenience of calculation. A bottom placing groove 3 is provided on the top of the placing base 1. The counterweight body 2 is inserted into the bottom placing groove 3. Two hook rope blocks 10 are fixedly installed on the corresponding two sides of the counterweight body 2. A guide rope block 16 is fixedly installed on the corresponding two sides of the counterweight body 2 and above the hook rope block 10. A guide rope groove 17 is provided on one side of the guide rope block 16. The cross section of the counterweight body 2 is an I-shaped structure. A connecting block 4 is fixedly installed on one side of the counterweight body 2. A connecting groove 5 is provided at one end of the counterweight body 2 away from the connecting block 4. The connecting block 4 cooperates with the connecting groove 5 to facilitate the connection of multiple counterweight bodies 2 when they are placed.

[0021] A first inner mounting groove 11 is provided on one side of the bottom of the rope hook block 10, and a rope limiting strip 12 is rotatably connected inside the first inner mounting groove 11. A limiting groove 13 is provided on the other side of the bottom of the rope hook block 10, and the rope limiting strip 12 is inserted into the inside of the limiting groove 13. A rope limiting plate 14 is fixedly installed on one side of the rope hook block 10 and on both sides corresponding to the limiting groove 13. A fixing screw 15 is inserted into the inside of the rope limiting plate 14, and the fixing screw 15 passes through the rope limiting strip 12.

[0022] A number of shock-absorbing springs 6 are fixedly installed on the bottom of the inner wall of the bottom placement groove 3, and two bottom mounting plates 7 are fixedly installed on the top of the shock-absorbing springs 6. Limiting blocks 8 are fixedly installed on the tops of the two bottom mounting plates 7. A bottom limiting slot 9 is opened at the bottom of the counterweight block body 2, and the bottom limiting slot 9 cooperates with the bottom mounting plate 7 and the limiting block 8. When the counterweight block body 2 is lowered, the deformation of the shock-absorbing springs 6 can be used to reduce the impact force on the vehicle.

[0023] Counterweight limit installation grooves 18 are provided on the corresponding sides of the counterweight body 2, and the counterweight limit installation grooves 18 are internally rotatably connected to the counterweight limit strip 19, and the counterweight limit strip 19 is internally rotatably connected to the rotating button 20. The bottom of the rotating button 20 passes through the counterweight limit strip 19 and is fixedly installed with a bottom limit plate 21. Limit rotation grooves 22 are provided on the corresponding sides of the placement base 1, and the bottom limit plate 21 is inserted into the inside of the limit rotation groove 22 and cooperates with it, which increases the stability of the placement base 1 and the counterweight body 2 after installation.

[0024] In summary, the new counterweight device suitable for dump trucks, when in use, first place the placing base 1 on the dump truck that needs to be tested. According to the different loads of the dump truck, multiple placing bases 1 can be placed. Then the counterweight body 2 needs to be lifted to the dump truck by a crane or other large equipment. When lifting, the lifting rope is placed inside the hook rope block 10, and then the rope limit bar 12 is rotated upward until one end is inserted into the limiting groove 13. Then, the fixing screw 15 is used to pass through the rope limit bar 12 and the rope limit plate 14 at the same time to limit it and make the connection of the lifting rope more stable. Then, the counterweight body 2 is suspended above the placing base 1 by the crane, and its position is adjusted by the staff so that the counterweight body 2 can be located directly above the placing base 1. As the crane continues to be lowered, the counterweight body 2 is inserted into the bottom placing groove. 3, and the bottom mounting plate 7 and the limiting plug block 8 enter the bottom limiting slot 9. When lowering, the deformation of the shock-absorbing spring 6 is used to buffer it to avoid damage to the vehicle caused by a fast lowering speed. After the lowering is completed, the counterweight limit bar 19 is rotated downward by 90° until the bottom limit plate 21 can be inserted into the limiting rotary groove 22, which means that it is installed in place. When the bottom limit plate 21 is inserted into the limiting rotary groove 22, the rotating knob 20 is rotated so that the bottom limit plate 21 is laterally located inside the limiting rotary groove 22, thereby completing the connection between the placement base 1 and the counterweight body 2, and the lifting rope can be taken out from the inside of the first inner mounting groove 11. When placing multiple counterweight bodies 2, the placement bases 1 are placed side by side, and the connecting groove 5 on one side of the rear counterweight body 2 is located on the outside of the connecting block 4 on the side of the previous counterweight body 2.
