Building robot and high-load-dead-weight-ratio mechanical arm assembly thereof

Abstract

The invention discloses a high-load-dead-weight-ratio mechanical arm assembly. The high-load-dead-weight-ratio mechanical arm assembly comprises a hydraulic arm assembly provided with a plurality of joint assemblies connected in sequence, each joint assembly comprises a main base, a first hydraulic assembly, an auxiliary base and a universal coupling, the main bases and the auxiliary bases are connected through the universal couplings between the main bases and the auxiliary bases, main mounting parts are arranged on the main bases, auxiliary installation parts are arranged on the auxiliary bases, the two ends of the first hydraulic assemblies are correspondingly connected with the main mounting parts and the auxiliary mounting parts, and the two main mounting parts are not symmetrical about the orthographic projection of any shaft of the universal couplings. The invention further discloses the building robot. The positions of the hydraulic assemblies beside the universal couplings are reasonably arranged, so that the mechanical arm assembly can take and place materials at any angle and any position within the working length, the load-weight ratio of a mechanical arm can be remarkably increased, the flexibility and positioning precision of the robot are improved, the high-load-dead-weight-ratio mechanical arm assembly can be suitable for various indoor and outdoor complex ground working environments, and the cost of a robot moving body is reduced.

Description

technical field [0001] The invention relates to the technical field of construction robots, in particular to a construction robot and a high load-to-weight ratio mechanical arm assembly thereof. Background technique [0002] With the continuous advancement of robot technology, the application of robots can be seen everywhere in the fields of processing and manufacturing, life services, aerospace, medicine and medical engineering. With the arrival of the population aging phenomenon, fewer and fewer young labor force enter the construction industry to engage in high physical strength and high risk, which makes the construction industry difficult to recruit and high cost. In recent years, with the gradual rise of construction robots , to solve the existing labor problems in the construction industry. [0003] The existing construction robot structure is through the structural transformation of the industrial robot, and the corresponding work is carried out by changing the stru...

Problems solved by technology

However, the mechanical arms of existing industrial robots are mostly used to work on a stable fixed point. In order to carry a larger load and ensure the rigidity of the mechanical arm structure, the structure of this type of mechanical arm is often relatively simple, usually using an integrated The structural manufacturing method, which processes the entire rigid body and then hinges each rigid body, has the disadvantages of heavy weight, poor flexibility, poor positioning accuracy, high load-to-weight ratio, and high cost of execution terminal changes, which cannot be well applied to mobile construction robot

If it is necessary to increase the load capacity and supporting force of this type of construction robot, it is necessary to increase the weight and attachment area of ​​the robot's mobile body, which also increases the cost of the robot's mobile body, reduces the load-to-weight ratio, and makes it inconvenient to move. Construction work done outdoors with limited or no room for movement indoors
