Abstract

The invention provides coal mine area mine hole supporting equipment. The equipment comprises a base with at least one air cylinder arranged on one side and is characterized in that a shielding plateis fixedly installed at the upper end of the air cylinder, supporting devices are symmetrically arranged at the front end of the shielding plate, an anti-collapse device is arranged on one side of each supporting device, the anti-collapse devices are movably installed on the base, and auxiliary protection devices are further installed in the middles of the supporting devices. According to the coalmine area mine hole supporting equipment, the supporting devices cooperate with the anti-collapse devices, so that when the supporting devices are excessively pressed, the anti-collapse devices can give reverse supporting force, and the supporting effect is further guaranteed; and the auxiliary protection devices are arranged, so that constructors are protected to a certain extent when accidentshappen.

Description

technical field [0001] The invention belongs to the technical field of mine protection equipment, and in particular relates to a mine support equipment in a coal mine area. Background technique [0002] Coal mines in my country are mainly mined underground, and a large number of roadways need to be excavated underground. Using roadway support to keep the roadway smooth and the surrounding rock stable is of great significance to the construction and production of coal mines. The support equipment in the prior art mostly uses simple hydraulic support. The corresponding safety protection and locking structure make the support equipment less safe and cannot provide good protection for construction workers. Therefore, the improvement of mine support equipment is worthy of our research. [0003] For example, Chinese patent literature discloses a new type of coal mine underground support device, [Application No.: 201821969981.0], which includes a first protective plate, and a firs...
