Problems solved by technology

[0002] At present, the detection of verticality and aperture in the construction process of manually excavating piles in construction projects is usually carried out by using the method of adding a measuring scale with a pendant hammer. Although this method is simple and effective, due to the various pipelines (such as machine pipes, water pump hoses, air supply pipes, etc.), supports (wall retaining concrete inner formwork and its brackets), so that each inspection requires 2 to 3 people to cooperate with moving obstacles, setting out lines, vertical alignment, and measuring The cycle process of ruler and take-up, the detection efficiency is very low; for the verticality detection of small-diameter manual excavation piles, etc., during the detection process, the construction personnel and quality supervision personnel move the hammer wire pole up and down in the mold (hole) It is easy to encounter obstacles, which increases the difficulty of detection and the safety hazard of personnel operation

Embodiment 1

[0030] Such as figure 1 , a convenient gravity laser verticality and aperture detector, which includes:

[0031] The support rod 1 that can be placed flat has a level bubble installed on its top, which is convenient for adjusting the level of the support rod;

[0032] Rotating arm 2, one end of which is hinged to the middle part of the support rod 1, when the supporting rod 1 is placed horizontally, the motion plane of the rotating arm 2 rotation is a horizontal plane, and the rotating arm 2 is provided with an emitter 3 that emits light in the direction of gravity.

[0033] In this embodiment, the support rod 1 is hinged by two equal-length rods, and can be opened and closed around the hinge shaft in the middle.

[0034] In this embodiment, the axis at the joint between the rotating arm 2 and the support rod 1 is coaxial with the hinge axis at the middle of the rotating arm 2 itself.

[0035] In this embodiment, the emitting head 3 is an emitting head 3 capable of emitting...

Abstract

The invention relates to the field of construction equipment, in particular to a gravity type laser perpendicularity and aperture detector. The detector comprises a supporting rod capable of being placed horizontally and a rotary arm, wherein a level bubble is arranged on the top of the supporting rod, one end of rotary arm is hinged to the middle of the supporting rod, the rotary arm rotates on the horizontal plane when the supporting rod is placed horizontally, and an emission head used for emitting light towards the gravity direction is arranged on the rotary arm. By the adoption of the portable gravity type laser perpendicularity and aperture detector, perpendicularity and aperture during manual hole digging pile body pore-forming can be detected conveniently and efficiently, and potential operation hazards are reduced.
