Problems solved by technology

[0002] At present, the temporary support methods used in the underground excavation face are mainly "capped point column" support and front probe beam support. These simple temporary supports have low support strength, extremely small support surface, Serious defects such as poor support effect and poor safety cannot effectively guarantee the safety of the excavation face, and cannot meet the needs of fast and safe construction of fully mechanized excavators, resulting in a relatively low average monthly footage and tense excavation continuity

Embodiment Construction

[0030] The technical scheme of the present invention will be described in detail below according to the accompanying drawings. For ease of understanding, the direction in which the inner frame stretches out is defined as the right part.

[0031] Such as Figure 1-8 As shown, the excavation working face self-moving temporary support hydraulic support of the present invention comprises a four-column inner frame, a four-column outer frame and a hydraulic system; wherein: the four-column inner frame consists of two horizontal inner frame top beams 10, two It consists of a horizontal inner frame bottom beam 13 and four inner frame telescopic columns 11, the four inner frame telescopic columns 11 include two outer frame left columns 11a and two outer frame left columns 11b (see 5-6) . The four-column outer frame is composed of two horizontal outer frame top beams 1, two horizontal outer frame bottom beams 2 and four outer frame telescopic columns 4, and the four outer frame telesco...

Abstract

The invention discloses a driving face self-moving temporary support hydraulic support and a support method thereof. The driving face self-moving temporary support hydraulic support comprises a tetrastyle inner support, a tetrastyle outer support and a hydraulic system. The inner support and the outer support are both made of two transverse top beams, two transverse bottom beams and four elastic stand columns, a plurality of longitudinal beams are arranged on the two transverse top beams to form a top support of a supporting top plate, the tetrastyle inner support is embedded with the outer support to form a pull-draw type combined support, the hydraulic system enables the inner support and the outer support to be capable of lifting and mutually pulling and drawing, and forward movement of the hydraulic support along a working face is achieved. The driving face self-moving temporary support hydraulic support is a novel driving face mechanization temporary support device. The support is a tetrastyle support and can automatically move so that supporting intensity and supporting areas of the temporary support are improved, tunneling construction speed and safety can be substantially improved, and technical supports for rapid and safe tunneling are achieved.

Description

technical field [0001] The invention relates to the technical field of temporary support for roadway excavation working faces. Background technique [0002] At present, the temporary support methods used in the underground excavation face are mainly "capped point column" support and front probe beam support. These simple temporary supports have low support strength, extremely small support surface, Serious defects such as poor support effect and poor safety cannot effectively guarantee the safety of the excavation face, and cannot meet the needs of fast and safe construction of fully mechanized excavators, resulting in a relatively low average monthly footage and tense excavation continuity. Therefore, need a kind of new excavation face mechanized temporary support equipment very much. Contents of the invention [0003] The purpose of the present invention is to solve the deficiency of the traditional temporary support method in roadway excavation, and to invent a self-mo...
