SANY EBZ318H Coal Roadheader Hard-Rock Tunnel Excavating Machine for Sale
Benefits & Features
1.Efficient Rock Breaking
The maximum hardness of rock which can be cut at time of joint development is f11;
We can design, process and manufacture cutting teeth on our own to eliminate the need for import;
Three-stage vibration damping technique: patented cutting teeth arrangement, flexible transmission and differential pressure damping structure are used to systematically solve the problem of impact damage by cutting vibration on the overall machine and critical and important parts.
2.Efficient Dust Removal
Integrated dust removal system innovated in the industry: long-pressure short air ventilation curtain type dust removal system with a total dust removal efficiency of ≥97%.
On-board mining-purpose dust-proof suction system: fundamentally solve the problem of harm to health of staff by construction dust and powder.
3.Centralized Lubrication
The roadheader employs centralized lubrication technique so that lubrication is easy greatly saving oil injection time and reducing work load of underground workers.
- Q:When the rotary drilling rig is working, how does the rotated soil enter into the slag bucket?
- (1) rotary drilling rig is the soil dust into the drilling bucket by drill pipe and the drill bit rotation and gravity, the soil dust filled with drilling bucket, lifting drill unearthed, so by drilling bucket rotation, soil cut, lifting and unearthed, repeatedly into the hole. According to drilling technology, it is divided into casing drilling method and stable liquid wall drilling method without casing.(3) the rotary drilling rig is mainly composed of operating system, power system, running system and drilling system (guiding column, drill pipe, drilling barrel, long and short spiral rod). Its operating system is mainly controlled by computer and hydraulic transmission. The power system is provided by diesel engine to drill and walk power, and adopts caterpillar type walking system (usually modified by excavator walking system).(4) drilling system is composed of drill bit and drill rod. Drill bit is made up of spiral drill and slag bucket. The drill bit is varied, and different drill bits can be changed according to different geological conditions. The chip type pumping rod drive a rotating drill bit drilling pressure and transfer required torque. The drilling rig is equipped with vertical and horizontal leveling system to ensure the verticality of the bore and to show the depth of the drill tube at any time and to keep abreast of the drilling conditions. The drilling rig has wide application range and high efficiency, and different drill bits can be configured according to different stratum during construction:
- Q:What bucket teeth are used in rotary drilling machines?
- Rotary drilling machine selection bucket teeth must select special rotary drilling machine bucket teeth, after all, in the ground tens of meters, can not be like excavators, to spin wear-resistant
- Q:What is a rotary cast in place pile?
- For the good cohesive rock soil layer, dry or clear water drilling technology can be adopted, without mud wall protection. For loose and easy to collapse formations, or groundwater distribution, unstable wall, it is necessary to use static mud wall drilling technology, and put in protective wall slurry or stabilizing liquid into the hole.
- Q:Xr220a rotary drilling machine drilling 2 meters hole can reach 80 meters, its maximum drilling depth is 80 meters, the maximum aperture is 2 meters.
- Attention is conditional, and there is the maximum drilling depth is 79 meters, there are 1 meters gap, if you count the drill bucket distance, barely enough.
- Q:Rexroth leveling sensor rotarydrilling rig
- Solar term door position sensorRole: throttle position sensor is to monitor the throttle angle of opening size, determine idle speed, full load and acceleration and deceleration conditions to implement and throttle opening stateCorresponding fuel injection control. Failure effect: idle speed is high or low, or cause runaway phenomenon.
- Q:Is the rig operator tired?
- MQT-130/2.0 pneumatic anchor drillScope of application:Tunnel: MQT-130/2.0 type pneumatic anchor drilling machine is widely applicable to the rock hardness is less than F10, especially suitable for coal roadway bolting work, can drill and drill hole roof bolt, anchor hole, can also stir and install resin cartridge type bolt and cable, without other devices, you can achieve a bolt nut tighten the installation, to achieve initial anchor pretightening force requirements.
- Q:How heavy is the 250 auger rig?
- Machine signs are marked by weight, and manufacturers vary in weight.
- Q:How much do you charge for a day rig?
- You have to talk about it yourself, because the larger the rig, the higher the purchase price, the fewer people you buy. In addition, the rig is generally equipped with 2-3 manipulator, manipulator of the wages included in the rent, maintenance costs are also included in the rent and other low value consumable things such as drilling teeth, wire rope is not included in the rent, who who is responsible for the rent.
- Q:What kinds of rock entry models are there in the 31 rotary drilling rigs? Request introduction!
- The rock type, strictly speaking, SR250 above can be into the rock, but the real into the current mainstream rock drill rig or 31 SR280R and SR360 three generation, the future of C8 series rotary drilling rig SR285RC8, SR315RC8, SR385RC8 as the main push models will gradually replace SR280R and SR360.
- Q:The difference between the rotary drilling bored pile and long spiral bored concrete pile?
- Rotarydiggingmachine, also known as rotary drilling rig. The utility model is a tool for road traffic and high-rise building construction. The rotary drilling rig is a kind of comprehensive, it can use the short helix bit dry digging, can also be used in wet digging rotary drill mud case. Rotarydiggingmachine with hammer drill hole digging work pieces after hard formation. If the enlarged head drilling tool is used, the reaming operation can be carried out at the bottom of the hole. Rotary digging machine adopts multi-layer telescopic auxiliary drilling drill pipe, less time, low labor intensity, without mud circulation deslagging, cost saving, no pollution, infrastructure construction is especially suitable for the construction of the city.
