Description

Technical Field

[0001] This invention relates to the field of engineering machinery technology, and in particular to a kiln body brick-removing machine specifically designed for cement rotary kilns and driven by an electric motor. Background Technology

[0002] Needs for operations inside kilns and in confined spaces: In scenarios such as maintenance and dismantling inside kilns, diesel equipment is unusable due to its high noise and severe exhaust pollution. Electric equipment has the inherent advantages of zero emissions and low noise. Manual brick removal is inefficient and costly: Traditional manual operations are inefficient and face pressure from labor shortages and continuously rising costs. Mechanized and intelligent brick removal equipment is an inevitable way to reduce costs and increase efficiency. The market for retrofitting existing kilns has generated a massive demand for brick removal operations, providing a broad application scenario for specialized equipment. Summary of the Invention

[0003] The purpose of this invention is to provide a special electrically driven brick-removing machine for cement rotary kilns, which overcomes the shortcomings of the prior art by providing a special electrically driven brick-removing machine for cement rotary kilns that optimizes the mechanical properties of brick walls and block walls to achieve precise, efficient, and low-dust demolition.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a special electric-driven brick-removing machine for cement rotary kilns, including a main drive structure, an upper control structure and an electric control structure;

[0005] The main drive structure includes a drive base, a drive chain track assembly located on the outside of the drive base, and a front pusher structure.

[0006] The aforementioned upper control structure includes a frame assembly connected to the drive base, a powertrain assembly, a control cab structure, an operating pedal structure, a hydraulic control structure, an operating arm structure, and an air conditioning system structure.

[0007] The power control structure includes a battery pack structure located in the vehicle frame assembly and a high-voltage control box connected to the battery pack structure.

[0008] The aforementioned operating body structure provides the electrical energy required for movement operation through the electric control structure set in the upper body control structure, and the hydraulic control structure set in the upper operating body structure provides the hydraulic energy required for the operation of the operating arm structure. The operating room structure set in the upper operating body structure is connected to the operating pedal structure, the operating arm structure, the hydraulic control structure, the electric control structure, and the power system assembly.

[0009] The battery pack structure includes a battery pack frame assembly, a battery pack body disposed in the battery pack frame assembly, and a battery pack shock absorption mechanism disposed at the lower part of the battery pack frame assembly.

[0010] The boom structure includes a boom connecting base connected to the frame assembly, a main boom body, a main boom body control cylinder, a stick body, a boom, a hammer cylinder, and a vibrating hammer.

[0011] The control room structure is connected to the battery pack connection structure; a movable battery pack mounting bracket structure located at the rear of the control room structure is connected to the battery pack. The movable mounting bracket structure includes a side-end connecting seat at the rear of the control room structure, a movable flip-rod assembly hinged to the side-end connecting seat, a battery pack fixing bracket at one end of the movable flip-rod assembly, a control linkage rod assembly located on the upper side of the battery pack fixing bracket and connected to the control room structure, and a locking control lever connected to the control linkage rod assembly.

[0012] The beneficial effects of this invention: Unlike general excavators equipped with hydraulic breakers, this 4.5T brick demolition machine integrates a dedicated hydraulic shears / gripper or a high-frequency, low-impact breaker head, optimized for the mechanical properties of brick and block walls, achieving precise, efficient, and low-dust demolition. Increased work efficiency: Its work efficiency is expected to be 10-15 times higher than traditional manual labor, and it can operate continuously, significantly shortening the construction period. Precise operation capability: Thanks to the rapid response of the electro-hydraulic system, it can achieve micro-motion control, providing unparalleled advantages for scenarios requiring partial structural preservation or partial demolition.
