Problems solved by technology

When moving the front probe beam during work, it must be manually removed from the roof, and the lifting ring is removed and installed on the next anchor rod. This kind of support has the following disadvantages: ①The support of the front probe beam to the empty roof area has no initial support force , poor safety and reliability; ②The front probe beam is in point contact with the roof, which cannot effectively protect the roof in the empty roof area; ③The operation process is complicated, and its movement is manual work, and the support operation takes a long time, which reduces the excavation operation time

Abstract

The invention relates to a machine leading support. A support beam is hinge with the top of revolving arm of drill machine; the top part and the support beam are hinged with the lifting connecting rods near the hinge point; another ends of said two lifting connecting rods are hinged; said hinge points are above the revolving arm and the support beam; a lifting hydraulic cylinder is hinged between the hinge point and the revolving arm; the front end of support beam is hinged with a shield beam; the parts of support and shield beam that near the hinge point are hinged with support beam connecting rods; another ends of said two support beam connecting rods are hinged; the hinge points are under the support and shield beam; and the hinge points of said two support beam connecting rods and the support beams are hinged with support beam hydraulic cylinder. The invention can save time, improve efficiency, improve the safety, and simplify the operation.

Description

Technical field: [0001] The invention relates to an airborne advance support device, which is a kind of equipment matched with a comprehensive excavator to provide temporary support for the empty top area for the development of underground roadways in coal mines. Background technique: [0002] At present, during the development of coal mine roadways in my country, a number of front probe beams (steel pipes or square steel) are used to hang on the roof along the direction of the roadway to explore the empty roof area in the empty roof area, so as to support the roof and prevent personal injury caused by roof fall. ACCIDENT. When moving the front probe beam during work, it must be manually removed from the roof, and the lifting ring is removed and installed on the next anchor rod. This kind of support has the following disadvantages: ①The support of the front probe beam to the empty roof area has no initial support force , Poor safety and reliability; ②The front probe beam is ...
