Description

Technical Field

[0001] The utility model relates to the technical field of protection of cutting heads of comprehensive excavators, in particular to a telescopic and foldable gun head protection device for anchor excavators. Background Art

[0002] The tunnel boring machine is an important equipment used in underground coal mine excavation. The tunnel boring machine is equipped with a blasting head (cutting head) to cut the coal and rock walls. After completing the cutting task, the tunnel boring machine is directly stopped, and then the blasting head (cutting head) is dropped to the ground, and then the tunnel is supported manually. During the support operation, sometimes due to the slippery ground, the support personnel may easily touch the sharp cutting teeth on the blasting head (cutting head). At the same time, if manual misoperation occurs, causing the blasting head (cutting head) to move, it will also cause harm to the support personnel and lead to safety accidents.

[0003] In excavation operations, a protective cover is generally provided on the gun head (cutting head) to reduce the occurrence of safety accidents. The currently used gun head (cutting head) protective cover of the comprehensive excavator is a fixed integral type, welded with angle steel and steel bars, which has the problems of large overall volume, heavy use, large space occupation due to non-foldability, high damage rate, high processing cost, and requires multiple people to move and operate, which is time-consuming and labor-intensive. If improper coordination is required, safety accidents may easily occur, which is not conducive to on-site use and safety management. At the same time, the safety management requirements of underground coal mine operations require that the cutting head guard must maintain a safe distance from the cutting head, which again increases the size, weight and cost of the guard. Therefore, the utility model proposes a retractable and foldable gun head protective device for anchor miners to address the deficiencies in the prior art. Utility Model Content
