The invention discloses a tunnel anchor rod construction angle control device which comprises an n-shaped connecting plate, a fixing base is arranged at the bottom of one end of the connecting plate, a fixing screw is arranged on the top face of the connecting plate, and the bottom of the fixing screw penetrates through the connecting plate to be fixedly connected with a screw bottom plate. The screw bottom plate and the fixed base are arranged in a cavity formed by the fixed base and the connecting plate in parallel, the other end of the connecting plate is connected with an adjusting base, one side of the adjusting base is connected with a fixed base, and a 360-degree protractor is fixedly arranged on the side face, away from the connecting plate, of the fixed base. The 360-degree protractor is connected with a drill rod clamping groove through a rotating shaft, a pointer is fixedly connected to the end face, close to the 360-degree protractor, of the rotating shaft, the pointer and the drill rod clamping groove synchronously rotate through the rotating shaft, and a fixing mechanism is arranged on the side face, away from the 360-degree protractor, of the drill rod clamping groove. The drill rod inserting angle can be conveniently controlled, the drill rod angle can be conveniently fixed, it is guaranteed that the drill rod construction angle does not deviate, construction is accurate, and operation is convenient.
Description
technical field [0001] The invention belongs to the technical field of tunnel bolt installation, in particular to a tunnel bolt construction angle control device. Background technique [0002] The angle of the anchor rod (locking foot, system anchor) is not easy to control during the construction process. For example, the locking foot anchor, system anchor, and advanced anchor need to control the angle during construction, and the different directions are subjected to force on it. The impact is great, but in actual construction, the workers' control of the angle is entirely based on experience, and cannot meet the requirements of construction drawings and specifications. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a tunnel bolt construction angle control device, which solves the problem that the existing operation method is not applicable and the insertion angle cannot be well controlled. [0004] In order to achieve the above purp...
