Detailed Description
The following detailed description of the present invention is provided in conjunction with the accompanying drawings, but it should be understood that the scope of the present invention is not limited by the following detailed description.
Throughout the specification and claims, unless explicitly stated otherwise, the word "comprise", or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated element or component but not the exclusion of any other element or component.
Fig. 1 to 2 show a schematic structural diagram of an adjustable quilt device for tunnel blasting construction according to the preferred embodiment of the present invention, which comprises a mounting seat 9, a rotating shaft 10, a door frame 3 and a quilt 8. Referring to fig. 1 and 2, two installation seats 9 are oppositely distributed left and right, the two installation seats 9 are respectively installed on two side walls in the tunnel 1, the specific installation position is determined according to the field, and the distance between the outside of the door frame and the tunnel face 2 needs to be ensured to be safe during blasting. Each mounting seat 9 is provided with a rotating shaft 10, so that the mounting seat 9 comprises an upper clamping groove and a lower clamping groove which are fixed on the side wall of the tunnel 1, the lower clamping groove can be arranged at the arch foot position of the tunnel 1, and the upper clamping groove is arranged at the arch waist position of the tunnel 1.
