Abstract

The invention provides a ventilation device comprising an air duct assembly; the air duct assembly comprises multiple air ducts which are successively arranged in a sleeved mode; adjacent two air ducts are movable relative to each other; a running gear which comprises a lifting mechanism and a pedestal having wheels, wherein a first end of the lifting mechanism is installed on the pedestal and a second end of the lifting mechanism supports the air duct assembly. Through the installation of the running gear on the air duct assembly, along with the continuous propulsion of the tunnel face, the running gear can move the air duct assembly to the tunnel face continuously; therefore, the problem of increased material consumption and manual work load due to continuous installation of guide rails and pulleys on the top of a tunnel during ventilation using a ventilation device in the prior art is solved.

Description

Technical field [0001] The invention relates to the technical field of tunnel construction equipment, and in particular to a ventilation device. Background technique [0002] In coal mining, mining or tunnel engineering, the face that is constantly advancing is usually called the "handling face". In the construction process of the extra-long tunnel by drilling and blasting, in order to ensure that the tunnel is in the fresh air flow, extractive ventilation is often used. However, the effective suction range of the draw-out ventilation is short and it is easy to produce vortex. At the same time, in order to reduce the damage of the blasting flying stones to the duct, the end of the duct should not be close to the face of the tunnel. [0003] In order to solve this problem, it is usually necessary to install a guide rail device on the top plate near the face of the blast before blasting. The guide rail is equipped with pulleys, which are connected to the flexible and free telescopi...
