Installation steps for concrete core drilling machine

1. Preparation before use

(1) Add 93# unleaded gasoline and high-grade lubricating oil. The amount of oil added can be based on the oil dipstick scale.

(2) Fill the column with lubricating oil and turn it into the handle and output shaft to check whether the feeding and turning are flexible and reliable.

(3) Prepare the water source.

(4) Check if the screws in each part are loose.

2, installation

After the concrete drilling core machine drill bit is in the hole position, the three walking wheels are lifted up, and the base is dropped to the ground. When the hole is drilled and the concrete strength is not high, the rig can be fixed by the weight of the rig. If the hole diameter is large and the rig's own weight cannot stabilize the rig, heavy objects (such as sand bags, etc.) can be placed on the chassis. Iron blocks, concrete blocks, etc.) Fix or hit two expansion bolts and press rods (such as channel steel) to fix the drill. The drill should be fixed firmly and must not be shaken, otherwise the drilling operation cannot be performed normally.

3, opening

After the above operations are completed, the hole can be opened, the drill bit is installed, the gasoline engine is started, and the water inlet pipe is put into the water tank. The water tank should be mentioned above the pump position, and then the gas is sucked into the water pump by hand, and the water pump is put into the water pump. The bucket can be placed on the ground. The throttle is adjusted to Zui, and it is gently rocked into the handle to make the drill bit slowly touch the ground. Open the hole to be smashed: first after the water is drilled, the feeding speed is slow, and the drilling pressure is small. No water work is allowed to avoid burning the drill bit and water seal.

4, normal drilling

When the hole is drilled to 2-3 mm deep, it can be transferred to normal drilling. At this time, the feed pressure is appropriately increased. The normal drilling is required: the feed pressure should be moderate, keep it even, and touch the coarse steel bar. The inlet pressure should be reduced. To do it, listen to the sound of the machine is normal, see if the orifice returns (takes water).

5, the final hole

Once you reach the depth you have taken, you can stop drilling. The requirements for stopping the drill are: first turn off the water after shutting down the device. If it is a deep hole, it can not immediately drill and stop the water. Instead, it must be punched with water for a period of time. The purpose is to rinse the rock powder in the hole to prevent the rock powder. Precipitation leads to buried drilling, which makes it difficult to take the core.
