Description
Technical Field
[0001] This invention relates to the field of construction robot technology, and in particular to a wall surface treatment robot. Background Technology
[0002] The treatment of building walls includes wall sanding, wall plastering, puttying, and wall painting. Traditionally, this work is primarily done manually, leading to problems such as low efficiency, high labor intensity, difficulty in quality control, significant safety risks, substantial material waste, and dust pollution that harms health. Therefore, automation technology using construction robots has emerged and matured, with wall treatment robots increasingly used for automated wall work. However, these robots come in various models, lack mature technology, and have inconsistent efficiency. In complex building scenarios, they still suffer from insufficient automation, low efficiency, instability, and a lack of time and labor savings. Summary of the Invention
[0003] The purpose of this invention is to provide a wall treatment robot to solve the technical problems of existing building wall treatment robots, such as insufficient automation and construction efficiency, inadequate stability, and insufficient time and labor saving.
[0004] The present invention provides a wall treatment robot, which includes a chassis, a lifting device mounted on the chassis, a working platform perpendicular to the lifting device, and a construction device mounted on the working platform; furthermore, in order to improve the stability and strength of the lifting device after it is deployed, as a preferred embodiment, an auxiliary support is inclinedly provided on one side of the lifting device, and the two ends of the auxiliary support are respectively fastened to the chassis and the lifting device.
[0005] Specifically, the chassis includes a support mechanism disposed around the periphery of the chassis, multiple first sensors disposed on the chassis for detecting the chassis balance, and an electronic control device electrically connected to the multiple first sensors for controlling the extension, retraction, and lifting of the support mechanism; preferably, the support mechanism is extended or retracted via an internal drive motor. To further coordinate with the multiple first sensors distributed on the vehicle body for automatic adjustment of the vehicle body balance, the support mechanism can also achieve vertical leveling via an internal drive device.
[0006] Specifically, the lifting device includes a main lifting unit and an auxiliary lifting unit slidably connected to the main lifting unit. The auxiliary lifting unit has a working platform slidably mounted along the height direction. The construction device includes a replaceable multi-axis construction component mounted on the working platform and a reel mounted on the chassis. The reel is connected to the working platform via pipelines for controlling the working platform and conveying materials. Since the construction device is also connected to the working platform, construction materials can be directly conveyed to the construction device for construction operations via the working platform. Furthermore, the vision module can effectively calculate the distance between walls and the condition of the walls through internal laser sensors and vision sensors, and then better control the operation of the entire machine through the electronic control device.
[0007] The wall treatment robot with the above-described structural design can replace traditional manual labor through the construction device. Under the action of multiple second sensors and electronic control devices within the construction device, it automatically detects the flatness of the wall surface and automatically sets the wall construction path, thereby effectively improving the quality and efficiency of wall construction. Preferably, the construction device can be equipped with different construction modules as needed to meet various construction requirements such as wall cleaning, sanding, puttying and smoothing, wall paint spraying, and painting. The specific settings of the different construction modules and units, as well as the multiple second sensors and electronic control devices, are already disclosed in related technologies and will not be elaborated upon here.
[0008] Furthermore, in order to further improve the convenience and stability of the construction equipment during the construction process, the aforementioned lifting device provides stable and reliable support for the construction equipment, and can also conveniently and flexibly adjust the construction height of the construction equipment according to construction needs. At the same time, it can also be used in conjunction with the chassis to easily and flexibly adjust the construction position.
[0009] Furthermore, to further improve the working efficiency and working area of the wall processing robot, the construction device also has the ability to cover the working range of the wall by lifting and lowering, and to ensure the stability and reliability of the module's contact with the wall by moving back and forth. With various modules and rotational degrees of freedom, it can work on various walls, obstacles and angles.
[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0011] While wall treatment robots are increasingly being used for automated wall surface work, the variety of models, immature technology, and inconsistent construction efficiency mean that they still fall short in complex building scenarios, lacking sufficient automation, efficiency, stability, and time and labor savings. Therefore, this invention presents a novel wall treatment robot that can be equipped with different construction modules to perform various wall surface work, such as wall cleaning, sanding, puttying, painting, and plastering. It boasts a high degree of automation. After being transported to the construction site, it can determine the wall's construction status via a vision module, adjust its height via a lifting device, adjust the distance to the wall via a forward / backward movement module, and achieve rotation and pitch of the main arm via a main arm rotation module and a main arm pitch module. Furthermore, it enables rotation and pitch of specific work modules via a sixth arm pitch and rotation module, allowing for work from all angles without blind spots and achieving high construction efficiency.

[0026] A lifting device 3 is fixedly installed on the top of the chassis 1, and the construction device 6 is installed on the top of the lifting device 3. The lifting device 3 enables the vertical lifting of the construction device 6. The lifting device 3 includes a main lifting 301 fixedly installed on the chassis 1. The main lifting 301 is configured as a multi-section parallel transmission lifting arm 303, and the multi-section lifting arm 303 is connected and transmitted through a chain assembly 304. The side of the last section of the lifting arm 303 is configured as a secondary lifting 302 to control the vertical lifting of the work platform 4.
