Problems solved by technology

These methods have great limitations. First, the excavator cannot work as freely as on land.
Secondly, when the excavator is working, the reaction force of foreign objects on the arm of the excavator will be transmitted to the base of the excavator, resulting in a change in the center of gravity of the excavator.
The change of the center of gravity of the excavator will affect the magnitude and direction of the force applied by the arm of the excavator, which will cause the excavator to not work normally and smoothly

Embodiment 1

[0046] In the embodiment of the present invention, the water pump unit includes four water pumps 11 and a total water tank 10, one end of each water pump 11 communicates with the water tank 6 in a rotating wheel 3, and the other end is connected with the total water tank 10 The number of the water pipes 5 is 4, and one end of each water pipe 5 is connected with the water pump 11, and the other end is respectively connected with the water tank 6 in the corresponding rotating wheel 3. Such as Figure 4 As shown, the cycle center-of-gravity mechanism 1 includes a housing wrapped around the balance control module and the water pump unit, the housing is provided with a pipe hole 9 for accommodating the water pipe 5, and the pipe hole 9 and the water pipe 5 are connected to each other. It is filled with seals, and in the actual implementation process, the seals can be made of a waterproof adhesive layer, which can ensure that the internal equipment of the circulation variable center...

Embodiment 2

[0053] The difference between the embodiment of the present invention and embodiment 1 is: as Figure 5 and 6 As shown, the water pump unit includes 4 telescopic pipes 12, 4 air pumps 13 and 4 water pumps 11, wherein two telescopic pipes 12 are arranged on the outside of the first transmission mechanism 4, and the other two are telescopic The pipeline 12 is arranged on the outside of the second transmission mechanism; each air pump 13 is respectively connected to a telescopic pipeline 12, and the telescopic pipeline 12 is inflated and deflated according to the demand so that the telescopic pipeline goes deep into or lifts off the water surface;

[0054] One end of each water pump 11 communicates with the water tank 6 in a rotating wheel 3 through a water pipe respectively, and the other end is in the external water environment, and is used to extract the water in the corresponding water tank or the water in the external water environment to the corresponding water tank 6 .

Abstract

The invention discloses a circular variable center of gravity rotary wheel mechanism for excavator water surface operations, which includes a first transmission mechanism, a second transmission mechanism, four rotary wheels and a circular variable center of gravity mechanism; the first transmission mechanism and the second The transmission mechanisms are parallel to each other, and the two ends are respectively connected with a rotating wheel; each rotating wheel is equipped with a water tank inside, and the outside of the water tank is a sealed structure, and the sealed structure is filled with gas; the cycle center of gravity mechanism includes a balance control module And the water pump unit, the balance control module is connected with the sensors arranged on the excavator, and is used to detect whether the body of the excavator is tilted, and generate corresponding control signals; The water tanks of the excavator are connected, and based on the control signal sent by the balance control module, the water in the water tank in the corresponding rotating wheel is adjusted to restore the balance of the body of the excavator. The invention can keep the body of the excavator in a stable and steady state all the time.

Description

technical field [0001] The invention belongs to the technical field of excavators, and in particular relates to a cyclic variable-center-of-gravity rotating wheel mechanism for excavator water surface operations. Background technique [0002] When the excavator is working, it especially needs a stable center of gravity to support the stability required for its work. Nowadays, there are more and more demands for surface excavator operations. Traditional excavators cannot move on the water surface due to their own weight and large crawlers. It can be moved forward by digging the shovel left and right, or put it on the boat, and use the boat as the wheel of the excavator to drive the excavator to work around. These methods all have great limitations. Firstly, the excavator cannot work more freely as on land. Secondly, when the excavator is working, the reaction force of the foreign object on the arm of the excavator will be transmitted to the base of the excavator, resulting ...
