Description

Technical Field

[0001] This utility model relates to a hole milling and roughening machine, belonging to the field of engineering construction technology. Background Technology

[0002] Since manual roughening often results in insufficient roughening, leading to potential quality issues, the existing roughening process is usually achieved using a roughening machine.

[0003] Utility model patent number 202420052613.9 discloses a pneumatic chiseling integrated machine, including a tracked chassis assembly with a chassis support platform. A rotating platform is mounted on the chassis support platform via a slewing support. An operating platform is mounted on the chassis support platform on one side of the slewing support. One end of a movable arm is mounted on the rotating platform. A pneumatic chiseling head is mounted at the end of the movable arm. A compressed air supply device for driving the pneumatic chiseling head is mounted on the upper surface of the chassis support platform. The compressed air supply device includes an air tank mounted on the upper surface of the front end of the chassis support platform. An air compressor is integrated on the air tank. The air outlet of the air tank is connected to the pneumatic chiseling head through an air passage.

[0004] Although the above-mentioned patent can realize the functions of road milling and wall milling, the current technology is not comprehensive and has the following drawbacks: roughening holes is a relatively difficult project to construct. It is impossible to quickly locate the holes to be roughened manually. At present, most of the roughening is still done manually by laying platforms and using handheld pneumatic roughening, which is inefficient, not environmentally friendly, and unsafe.

[0005] To solve one of the above problems, there is an urgent need for a hole milling and roughening machine. Utility Model Content

[0006] Based on the shortcomings of the existing technology, the technical problem to be solved by this utility model is: how to expand the working degree of freedom of the milling and chiseling head assembly by adding a robotic arm assembly, breaking through the limitation of single-degree-of-freedom operation of traditional chiseling equipment, and cooperating with the platform lifting and adjustment device to be suitable for hole milling and chiseling operations, and to improve the operational flexibility of the hole milling and chiseling machine. Therefore, a hole milling and chiseling machine is provided.

[0007] The hole milling and roughening machine of this utility model includes a machine body and a tracked chassis assembly. The machine body is rotatably mounted on the tracked chassis assembly via a rotary assembly. The tracked chassis assembly has track wheel assemblies on both sides. A power assembly is integrated on the machine body. The machine body is characterized by further including a milling and roughening head assembly and a construction platform. A platform lifting adjustment device for driving the construction platform to rise and fall is installed on the front side of the machine body. The milling and roughening head assembly is mounted on the construction platform via a robotic arm assembly.

By adding a robotic arm assembly, the working degree of freedom of its milling and chiseling head assembly can be expanded, breaking through the limitation of single-degree-of-freedom operation of traditional chiseling equipment. In coordination with the platform lifting and adjustment device, the operational flexibility of the hole milling and chiseling machine is improved.

[0009] The expanded working freedom of the milling and chiseling head assembly allows it to quickly move to the working position, enabling manual positioning of the holes to be chiseled, reducing manual adjustment time.
