Zoomlion ZR420 rotary drilling rig won the TOP50 Product of the Year

On March 29th, the 2013 Construction Machinery Product Development (Beijing) Forum and China Construction Machinery Annual Product TOP50 Awards Ceremony was held in Beijing. As the annual event of the construction machinery industry, the TOP50 evaluation aims to sort out and summarize the achievements made by the construction machinery industry in the past year in terms of technology and products, record the footprint of industrial technological progress, and guide the direction of engineering machinery products and technological progress. The target of the selection was locked in products (including foreign and domestic-funded enterprises) in the Chinese construction machinery market. The core criteria for selection were product innovation, market performance and application contribution.
Zoomlion ZR420 rotary drilling rig won the annual product TOP50 (2013) Product Award of China Construction Machinery.
Product Details:
The luffing system adopts an improved double dazzling structure, which improves the support of the mast cylinder and ensures the stability and reliability of the whole machine when entering the rock.
Under difficult drilling conditions, the three-rotation speed reducer configuration effectively enhances the braking effect and cooperates with the rear leg cylinder to effectively suppress the lifting of the front end of the body, further improving the stability of the entire machine, thereby ensuring the verticality of drilling and effectively avoiding the drill pipe. Breakage accident.
The main hoist uses a new type of encoder counting program to measure the depth of the hole more accurately. The new design of the boss and the climbing table, the wire rope is arranged more neatly to extend the service life; additional independent charging function is provided to prevent the stick from slipping. The accident occurred.
The addition of shock absorbers to achieve a full range of flexible drill pipe to prevent impact fatigue caused by power head damage and other malignant accidents, while adjusting the distance between the drill pipe and boring bar, can provide higher stability for the whole machine.
Technological innovation:
The industry has for the first time launched a joint construction process with all-casing, down-the-hole hammers, impact hammers and other equipment to significantly increase equipment development capabilities and save costs for customers. According to the drilling requirements for ultra-deep and large-aperture boreholes, optimization is as follows: The luffing mechanism is optimized, the working radius is flexibly adjusted, and the all terrain meets the requirements of construction stability; the overall matching of the power system, especially the constant power control of the hydraulic system is optimized, and the effects of pulse pressurization are added to the electrical transformation; The drill pipe's strength and hardness are optimized and matched to prolong its service life; in the case of extreme geological conditions, the drilling tool is easy to damage and the service life is short, and a detailed solution is proposed.
