Abstract

The invention relates to the technical field of mining mechanical equipment, and particularly relates to a movable temporary supporting device and a rib expanding and mounting integrated constructionmethod. The movable temporary supporting device comprises a first top supporting device, a second top supporting device and a moving frame driving device, wherein the moving frame driving device is correspondingly connected to the first top supporting device and the second top supporting device; the first top supporting device consists of a first top supporting support and a first supporting frame; the first supporting frame comprises a first telescoping support and a first stabilizing mechanism; the first stabilizing mechanism is connected to the first telescoping support in order to preventthe first telescoping support from inclining; the second top supporting device consists of a second top supporting support and a second supporting frame; the second supporting support comprises a second telescoping support and a second stabilizing mechanism; and the second stabilizing mechanism is connected to the second telescoping support in order to prevent the second telescoping support from inclining. According to the device, the first stabilizing mechanism and the second stabilizing mechanism are arranged, so that the device can be kept stable during forward moving, so that the top surface of a lane can be reliably supported.

Description

technical field [0001] The present application relates to the technical field of test equipment, and in particular to a construction method integrating mobile temporary support device and side expansion installation. Background technique [0002] At present, in the existing roadway excavation staggered support device, the lower part of the roof bracket is provided with a supporting column, and the stability of the supporting column is insufficient, and the device is prone to tipping during use. Contents of the invention [0003] The purpose of this application is to provide a mobile temporary support device and an integrated construction method for side expansion installation, which can support the top surface of the roadway and accommodate the excavator. When the excavator is driving forward, the first roof support device and the second The two supporting devices can move forward step by step, and by setting the first stabilizing mechanism and the second stabilizing mecha...
