Detailed Description
As shown in fig. 1 to 3, a horizontal drilling machine for tunnel secondary lining and primary concrete is composed of a motor 8, a drill rod 9 and a drill bit 10. The lower end of the portal 2 is fixed on a drilling machine supporting platform 11 in the tunnel through a fixing flange 7 and bolts. The longitudinal middle part of the portal frame is provided with a vertical supporting rod 21, and the two can be butted through bolts or welding. A vertical sliding sleeve 5 with a fastening screw 6 is matched with or fixed on the vertical supporting rod in a sliding way. The inner end part of the fastening screw is in threaded connection with the vertical sliding sleeve and then props against the corresponding side surface of the vertical supporting rod; when the fastening screw rod is tightly propped against the corresponding side surface of the vertical supporting rod, the vertical sliding sleeve is fixedly arranged on the vertical supporting rod, otherwise, the position of the vertical sliding sleeve on the vertical supporting rod can be adjusted so as to adjust the height of the transverse push rod and the drill hole.
The front end of the vertical sliding sleeve and the rear end of the horizontal transverse push rod 4 are fixed into a whole by welding. The included angle between the vertical supporting rod and the transverse push rod is 90 degrees. The front end of the transverse push rod is supported on the tunnel wall at the upper end of the drill bit through a wedge block. The transverse sliding sleeve 3 is matched on the transverse push rod in a sliding way. The motor is fixed on the lower end face of the transverse sliding sleeve through a motor fixing plate 13 and bolts 14, and each bolt is in threaded connection with the lower end face of the transverse sliding sleeve. The motor drives the drill bit to rotate through the drill rod. The upper end of the front part of the vertical supporting rod is provided with a steel wire rope ring 1. One end of the steel wire rope is fixed on the steel wire rope ring, and the other end of the steel wire rope is fixed on the nail ring on the opposite tunnel wall so as to stabilize the vertical supporting rod.
