Description

Technical Field

[0001] The utility model relates to the technical field of coal mine tunnel excavation and support machinery, in particular, to a digging and anchoring device with continuous shield support. In addition, the utility model also relates to a digging and anchoring integrated machine including the digging and anchoring device with continuous shield support. Background Art

[0002] In coal mining, safety is the first priority. There has been rapid progress in coal tunneling technology and equipment, especially the integrated drilling and anchoring machine, which has been continuously improved and updated to ensure safe production and improve efficiency of coal tunneling in mines.

[0003] Rock burst is the sudden destruction, collapse or ejection of coal and rock mass caused by the release of deformation energy under certain high stress conditions in the coal mining process. It is accompanied by loud noises and rock vibrations, often causing support damage, roof collapse, tunnel blockage, and casualties. Rock burst can also cause other mine disasters, including gas and coal dust explosions, fires, and interference with ventilation systems. In severe cases, it can also cause hazards similar to natural earthquakes, causing ground vibrations and building damage.

[0004] Some related technologies of temporary support devices are mostly used for protection of advance drilling, and cannot effectively prevent and suppress coal mine disasters such as rock burst. The patented designs of some related technologies of temporary support devices are installed on the cutting drum frame, which cannot complete the action of supporting and protecting while excavating, and truly achieve excavation and protection at the same time. In the existing support devices that realize excavation and protection at the same time, the shield used for support can usually only be raised and lowered to provide temporary support for the top of the coal lane. However, when the coal lane has a certain slope, the shield used for support is difficult to fully fit with the top of the coal lane, thereby affecting the support effect. For example, the Chinese utility patent with application number 201320509720.1 discloses a shield-type anchoring machine, in which the excavator, anchor bolter and advance drilling machine are installed as one, and a whole machine shield and a matching trolley device are added to achieve synchronous excavation and anchoring. The shield is placed above the whole machine, connected to the chassis through a cylinder, and can be raised and lowered. Such a shield structure is difficult to support different sections. When the coal roadway has a certain slope, the shield used for support is difficult to fit completely with the top of the coal roadway, and thus cannot effectively prevent and suppress coal mine disasters such as impact ground pressure.

[0040] In this embodiment, the vertical lifting member 300 and the oblique lifting member 302 can both adopt oil cylinders, or can adopt cylinders or linear motors capable of pushing the supporting body. The number of lifting mechanisms and angle adjustment mechanisms can be set according to actual conditions. When the lifting mechanism and the angle adjustment mechanism are both in one group, the lifting mechanism and the angle adjustment mechanism are both set at the center position in the width direction of the supporting body. When the lifting mechanism and the angle adjustment mechanism are in two groups, the lifting mechanism and the angle adjustment mechanism are both symmetrically arranged along the width direction of the supporting body. When the lifting mechanism and the angle adjustment mechanism are in multiple groups, the lifting mechanism and the angle adjustment mechanism are evenly spaced along the width direction of the supporting body. The number of vertical lifting members 300 and oblique lifting members 302 is set according to the supporting force required by the supporting body. When the required bearing force is greater, multiple lifting mechanisms and angle adjustment mechanisms can be selected for installation according to actual conditions to enhance the stability of the top shield device 200.

This side shield 400 structure will realize continuous temporary support of the side wall during the excavation operation of the excavator and anchor machine, ensure the safety of the operators, and further improve the stability of the support during coal roadway excavation.

[0042] In specific implementation, after the excavation and anchoring machine completes the excavation operation, the cutting device 600 is lowered to the bottom, and then the top anchor net to be supported is placed on the top shield, and then the angle adjustment mechanism is started. At this time, the support body is adjusted to the required angle and position, and then the lifting mechanism is started until it is lifted to the top plate of the tunnel, and the top anchor net is pressed against the top plate of the tunnel. After installing the top anchor net and anchor rod, first lower the lifting column to a safe working position. At this time, the support body does not interfere with the bottom end of the anchor rod that has been driven. Then adjust the angle adjustment mechanism to make the top shield device 200 reach a reasonable working angle. While the top shield device 200 is supporting, the auxiliary shield 400 will also move to both sides of the coal tunnel until it supports the side coal wall.
