Abstract

The invention belongs to the technical field of temporary supports of comprehensive tunneling faces under coal mine shafts and particularly relates to repeated-free-support temporary support equipment. The repeated-free-support temporary support equipment comprises an inner support group and an outer support group, the inner support group is arranged on the inner side of the outer support group and comprises two left and right inner supports, the inner supports have two inner supports on the inner left and right sides connected integrally through a cantilever beam of the inner support group and an intermediate support beam, and the cantilever beam of the inner support group is connected to two ends of the inner supports in a hinged manner; the outer support group comprises two left and right outer supports, the outer supports have two outer supports on the outer left and right sides connected integrally through a cantilever beam of the outer support group and an intermediate support beam, and the cantilever beam of the outer supports are connected to two ends of the outer supports of the outer supports in a hinged manner. By the arrangement, repeated-free support of a top plate and full cross-section active-support top plate can be realized, support process is simplified, a continuous operation mode that tunneling, temporary support and permanent anchor protection are performed synchronously is realized, and potential safety hazard of operation personnel under a suspending roof is avoided.

Description

technical field [0001] The invention belongs to the technical field of temporary support for fully mechanized excavation faces in coal mines, in particular to a temporary support device without repeated support. Background technique [0002] Before the rapid excavation temporary support bracket was developed, the temporary supports commonly used in the underground excavation working faces of most coal mines in China were as follows: one is the temporary support of the hanging ring piercing type front probe beam; the other is the airborne temporary support of the roadheader The third is to use multiple rows of single hydraulic props and high-strength I-beam beam support methods. Although these methods have relieved the pressure of the head-on support of the excavation working face to a certain extent and improved the support condition of the working face, there are still many deficiencies in the actual use process, and there are still great hidden dangers in safety. The safe...
