registered capital: RMB 10 million
Instrial and commercial registration number: 420621000007995
enterprise type: limited liability company (invested or controlled by natural person)
address: No.45 diamond Avenue, Xiangzhou District, Xiangyang City
note: the company can customize the matching equipment according to the specific requirements of customers
The suitable cross section of the tyre scraper is 1.6 * 1.6m; 1.8 * 1.8m; 2 * 2m section
suitable section of rail loader: 80 type 1.8 * 1.8m; 100 type 2.5 * 2.5m; 120 type 2.4 * 2.5m; 150 type, 2.5 * 2.8m; 160 Type 3.2 * 3.2m section. The selection of this model is mainly based on the mechanical equipment used to transport ore [such as rail transport, bucket car transport, shuttle car transport, etc.]
suitable section of crawler excavator loader: 80 type 2 * 2.2m; 100 type 2.6 * 2.6m; 100 type 2.2 * 2.4; 120 type 2.3 * 2.6m; 120 type 2.8 * 2.8; 150 type, 2.5 * 2.9m; 150 type 3.5 * 3.5m; 180 type, 2.8 * 3.3m; 180 type, 3 * 4m; 180 type, 4 * 4m; 200 type 4 * 4m; 220 type 4.5 * 4.5m; 260 type 5 * 5m; 312 type, 5 * 5m; 330 type 5 * 5m section
suitable section for inclined shaft with large slope: 80 crawler type 2.4 * 2.5m section with maximum working slope of 30 degrees; The maximum working gradient of 100 crawler type 2.6 * 2.6m section is 25 degrees; 120 crawler type 2.4 * 2.4m, maximum working gradient 28 degrees; 150 crawler type 3.5 * 3.5m, maximum working gradient 28 degrees; The maximum working gradient of 4 * 4m section of 180 crawler type is 32 degrees; 120 crawler type 2.8 * 2.8m, maximum working gradient 32 degrees; The maximum working gradient of 312 crawler type 5 * 5m section is 30 degrees
the main equipment commonly used in the construction of large section or full section are as follows:
rail transportation: gantry drilling jumbo, bolt support, vertical claw or rake bucket rail type rock loader (slag loader), 10 ~ 30 cubic shuttle mine car or mining big bucket car, 12 ton or 25t traction motor car, concrete spraying machine or transport pump, steel formwork jumbo combined supporting construction
trackless transportation: 3-arm or 4-arm tire and crawler electric hydraulic rock drilling jumbo, shotcrete anchor support, anchor jumbo, bucket crawler loader, 20 ~ 25 ton mining truck or pit truck [small secondary wheel and small Dongfeng], concrete spraying machine or delivery pump, integral steel formwork jumbo
the advantages of trackless shipping are high proction efficiency, good mobility, overcoming the practical advantages of working with large slope, small turning radius, strong working force, fast speed, not subject to conditions and so on. Although the initial investment is relatively high, the construction cost is low and fast, the engineering quality is good, and the safety and environmental protection are constantly improving. It is a common construction method in underground construction
thirdly, in the first 100 hours of slag raking machine, it plays a crucial role in the future life of slag raking machine. Many mine owners do not pay attention to it. When they realize it later, the machine is old and the internal parts have been "injured", so no matter how you maintain it, it may be irreparable. So the maintenance of the new machine is very critical for the later use
1. Regularly check and replace the hydraulic oil of the slag scraper, and select high-quality hydraulic oil in strict accordance with the use requirements
2. Regularly check the lubricating oil of the ore raking machine, and frequently beat, change and maintain it to ensure the lubricating effect
3. Regularly check the underground and internal lines of slag raking machine, and timely replace the aging lines
4. Check all parts of the machine regularly to see if they are firm Especially whether the road joint is loose (oil leakage)
5. For the crawler slag scraper, it is necessary to regularly check whether the links of each part are loose
the correct and perfect maintenance of the new car will determine the service life of the slag remover. Therefore, when using the slag raking machine, we must fully grasp and skillfully use the maintenance knowledge of the slag raking machine.
