YT29A air-legged rock drills are heavy-duty push-leg (air-legged) rock drills with low energy consumption, which are more suitable for drilling horizontal or inclined holes in medium-hard and hard (f=8-18) rocks, as well as drilling anchor holes upwards or downwards. It can be used with FT160A (or FT160B, 160C) according to the size of the roadway section and operating conditions, and can also be used with the drill truck or drill frame for dry or wet rock drilling. In addition, our company provides all YT29A rock drill parts as follows: piston, rotating sleeve, spiral rod, brass nut, valve set, ratchet, tower spring, manipulation valve, shank body, cylinder body, main body, brazing sleeve, brazing card, brazing card bolt, oiler, water injection valve body, fastening pin, ratchet pawl, air pipe nut, air pipe elbow, water needle, etc.
1、More output power
2、Rock drilling speed is faster
3、Super strong lubrication system to ensure the long time operation of movement parts
4、The whole machine has optimized design, the impact energy and impact frequency have reached an excellent match, it is your ideal rock drilling tool.
5、Gas and water linkage, quick return of the gas leg, air pressure adjustment and other institutions.
6、Control handle centralized with Back head, the mechanism is novel and convenient to operate, the muffler cover can effectively reduce the noise and change the direction of discharge at will to improve the working conditions in the field.Field operating conditions
Mining, traffic, tunnels, water conservancy construction, quarries and other work
1、Check the integrity and rotation of all parts (including rock drill, bracket, or rock drill cart) before drilling, fill necessary lubricant, and check whether the wind and waterways are smooth and whether the connection joints are firm.
2、Knock on the roof near the working face, i.e. check whether there are live rocks and loose rocks on the roof and second gang near the working face, and make necessary treatment.
3, the working surface of the flat shell hole location, is to be pounded flat in advance before allowing rock drilling, to prevent slippage or shell hole displacement.
4. It is strictly forbidden to drill dry eyes, and we should insist on wet rock drilling, turn on the water first and then the wind when operating, and turn off the wind and then the water when stopping drilling. When opening the hole, run at low speed first, and then drill at full speed after drilling to a certain depth.
5、No gloves are allowed to be worn by the drillers when drilling.
6、When using the air leg to drill the hole, pay attention to the standing posture and position, never rely on the body to pressurize, let alone stand in front of the rock drill under the work brazing rod, to prevent injury from broken brazing.
7、If abnormal sound and abnormal water discharge are found in rock drilling, stop the machine for inspection and find out the reason and eliminate it before continuing to drill.
8、When withdrawing from the rock drill or replacing the brazing rod, the rock drill can run slowly and pay attention to the position of the rock drill braze.
