Problems solved by technology

[0004] However, when the roadway is excavated by blasting, due to the unstable impact force generated by the blasting, it is easy to cause the support device to be overwhelmed by the impact force and topple over, resulting in the support device being unable to be used safely

Abstract

The invention discloses a roadway tunneling temporary anti-impact supporting device capable of absorbing blasting vibration energy. The device comprises an extension sleeve; a two-way hydraulic oil cylinder device is mounted in the extension sleeve; a controller is mounted on the outer side surface of the extension sleeve; an automatic impact adjusted compression device is arranged in the center of the side surface of the extension sleeve; and support base devices are arranged at the upper and lower ends of the extension sleeve. An impact baffle plate is impacted by impact force generated through roadway tunneling blasting for power relief through angle adjustment, so that a cylindrical fixed head is inserted in the inner wall of a roadway to increase the friction force between the deviceand the inner wall of the roadway, and the device is fixedly more stably; meanwhile, a ventilation pressure relief hole is formed in the impact baffle plate for effectively guaranteeing the tilting phenomenon of the device caused by the blasting impact; and oil is injected in the hydraulic oil cylinder through adjustment again to guarantee enough pressure between the support bases and the inner wall of the roadway, so that the roadway tunneling work is performed safely.

Description

technical field [0001] The invention relates to the field of equipment related to tunnel support, in particular to a temporary anti-scour support device for tunneling tunnels that can absorb blasting vibration energy. Background technique [0002] Shaft and roadway engineering refers to the general term for various passages and chambers excavated underground for mining and construction of other projects. Shaft and roadway excavation blasting includes flat (inclined) roadway excavation blasting, shaft excavation blasting and chamber excavation blasting. They are widely used in mines, water conservancy and hydropower, large oil depots and other projects. The biggest characteristic of tunneling and blasting operations is that there is only one free surface, which determines that it is difficult to deepen the depth of blastholes in tunneling and blasting. [0003] In the patent CN201710334917.9, an auxiliary support device for tunneling in coal mines can realize the effect of s...
