Problems solved by technology

[0002] With the large-scale construction of infrastructure in our country, the construction volume of underground spaces such as subway tunnels is increasing, and the current construction technology is still relatively backward. In the process of tunneling and excavation, blasting was used in the past. The original geological structure is destroyed, the safety hazard after blasting is great, and it is not environmentally friendly, and the impact of construction vibration is relatively wide. Therefore, drilling rigs are used for excavation, but the existing drilling rigs have the following problems:
[0003] 1) The artificial drilling rig has slow drilling speed, high labor intensity and huge labor cost
[0004] 2) Ordinary drilling rigs cannot adjust the operating angle during operation, and cannot meet the needs of all-round drilling, and the drilled holes cannot be cross-drilled to form a free surface
During the drilling process, the high-speed operation of the motor causes the entire drilling rig to vibrate and shift, which may easily cause the drilling head to deviate and make it impossible to position and drill, and cause the drill bit to be damaged.
Moreover, due to the complex environment of the construction site, most of the ground is uneven, which leads to the inability of the drilling rig to keep stable on the ground, which in turn affects the positioning of the drilling position
[0005] 3) The rotary-rolling drilling rig can only target looser rocks, which are as hard as granite and cannot be milled

Abstract

The invention discloses a multi-functional fully automatic drilling rig. The multi-functional fully automatic drilling rig comprises a control system and a folding lifting mechanism, wherein the folding lifting mechanism is provided with a rotary shaft which is provided with a linear feeding device, the linear feeding device is provided with an automatic propulsion mechanism, an installation baseof the automatic propulsion mechanism and a power spring sleeve a lead screw, the power spring is located between a leas screw nut and the installation base, at least one drilling mechanism is installed on the installation base, and a lead screw driving mechanism is used for driving the lead screw nut to drive the drilling mechanisms to move forwards and backwards through the power spring. The automatic propulsion mechanism is used for detecting the amount of compression of the power spring, if the power spring is compressed to a preset stop position, a signal is sent to the control system, the lead screw driving mechanism is controlled to stop acting, and the drilling mechanisms are driven through the elastic force of the power spring to move forwards; and if the power spring rebounds toa preset starting position, a signal is sent to the control system, and the lead screw driving mechanism is controlled to start acting. The structure is simple, the drilling rig is applicable widely,and drilling is more precise.
